PRESIDENT’S ADDRESS. 9

Ladies and Gentlemen – Another of our Society’s years has come to a close this day, and it devolves upon me to say a few final words before yielding up this presidential chair. In doing so, my chief desire is to repeat my thanks to the members for having placed me in so honourable a position, and for their kindness in sustaining me throughout the various evening meetings of the session.

It is a matter of much congratulation that these meetings have continued to be well attended, and that the Society itself has continued thoroughly to fill that position of scientific usefulness which was hoped for it at its first inauguration, now eighteen years ago. Such a lapse of time gives the opportunity of seeing how much good work has in the aggregate been done. And though, no doubt, in looking back through our volumes it will be found that different years have produced a varying amount of work judged by its importance, yet on the average we have reason to be well satisfied with what the successive numbers show us, seeing that the total represents a very important collection indeed of natural history facts and information. The work of the present year has, I think, fully maintained the good average attained in other sessions.

The Society too, has, as a whole, continued to prosper, and appears to be effectually carrying out the initial programme set forth on the first page of each volume of its “Transactions.”

On looking back to some of our earliest annual reports, I find that our numbers have doubled and trebled themselves since that time; and further that the list now embraces the names of many both at home and afar off, whose reputations are well known to science, and who are powerful additions to our Society’s strength. As compared, too, with those earlier times, the increased plumpness of our yearly volume tells of the greater amount of matter that is now every year contributed.

So, too, if prosperous finance is any test of success, we may look to the larger figures in our balance sheet, and the sufficiently satisfactory state of our “balance at the bank” further to fortify the favourable position which I desire to point out to you.

We have had an accession of twenty-one new members during the year, whilst seventeen have been removed by death, resignation, or other causes. But though the total losses from these causes have been but few, and those from death not above the average, yet these latter include some well-known names – the names of members of valued attainments, and of men whom the Society could ill spare.

Especially do we note with regret the premature loss, in only middle life, of one who had been a member of this Society from its commencement, who was also a life member of the Zoological Society, and whose death would have claimed attention from us as Norwich men, were it for no other reason than that he bore a name the very sound of which is instinct with ideas of Norfolk Natural History; one who was also a member of a family to which this Society, and the neighbouring Museum, owe a long and ever-increasing debt of gratitude.

Although the late Mr. John Gurney’s talents were never, I believe, especially directed to our class of study, yet his tastes for the bright and the beautiful were well known. And though his affliction had of late years debarred him from the complete visual enjoyment of the beauties of nature, yet his devotion to the improvement of the rural charms of his own home, and his public-spirited expenditure upon the scheme for the laying out of Mousehold Heath, and its appropriate development, showed that he had in him that form of mind out of which the true lover of nature’s creatures, as well as nature’s charms, necessarily arises.

But this side of Mr. Gurney’s mind will come home to us as naturalists much more forcibly when we recall the great act of his life, in which he was so heartily and so earnestly engaged when death removed him so suddenly in the midst of his useful and public-spirited career. I, of course, allude to his great Castle-Museum scheme for the removal of our grand Museum collection, with its surroundings, to a new and larger and more appropriate position on the Castle Hill. We all know the generous liberality with which he sought to ensure this grand scheme being carried out. We have all noted the quiet and business-like sagacity with which the various steps necessary for the effective doing of this work were taken under his inspiration. And I am sure we recognise how he was actuated not only by a desire to raise the scientific status of the county and city generally, but also to assist those Norfolk workers in nature’s fields whose accumulated results are now to be seen under this roof.

His large and increasing views for the good of this city, and its general welfare, have been so thoroughly and so publicly appreciated on all sides, that it is not necessary for me to add one word more. His name will remain as that of a public man at once generous and right-minded. And I can only hope on behalf of this Society, and that of other kindred ones, that nothing will occur to prevent the full development and carrying out of that Castle scheme, which, if effected, will, in my opinion, have a large and important influence not only upon the future scientific progress of Norfolk generally, but also upon the intellectual position which our famous old city will hold in the time to come.

Mr. Hampden G. Glasspoole, who has also recently died, had been a member of this Society from its commencement, and had contributed two papers to its proceedings. These were entitled “Biographical Memoirs of some Norwich Botanists,” and “Memoir of Lilly Wigg.” He had also published several papers in Science Gossip. He was for several years a member of the late Norwich Microscopical Society; and of the London Quekett Club.

Mr. Glasspoole was an accomplished botanist. For many of the later years of his residence at Ormesby, he was honorary curator of Botany at the Norwich Museum; and after his removal to London he held, for a short period, the office of botanist to the Alexandra Palace.

He will be remembered by us all as kindly, gentle, and genial; ever ready to help others with his time or his knowledge; and with all his stores of information, modest and unassuming.

He added one species to the British Flora, Carex trinervis, Devgl; and two species to our county list, namely, Ammophila Baltica, Leak, and Sparganium neglectum, Beeby.

As is well known, he was the eldest son of the late Capt. R. Glasspoole of Ormesby, who had himself presented many curios to our Museum, and who published a most interesting account of his experiences whilst a prisoner in the hands of Chinese pirates.

The Ornithology of Scotland has, in the death of Mr. Robert Gray, which took place at Edinburgh in February last, lost one of its ablest exponents. Commencing with “The Birds of Ayrshire and Wigtonshire,” which appeared in 1869, Mr. Gray, two years later, published the more important “Birds of the West of Scotland,” and at the time of his death was engaged on a similar work treating of the birds of the Eastern district of his native country. In this latter work he was, I believe, associated with Mr. William Evans of Edinburgh, who, it is to be hoped, will bring their joint labours to a successful issue.

Mr. Gray commenced public life in the City of Glasgow Bank, and it was whilst acting as Inspector of Agencies for that establishment that he was enabled to collect the information which so enriched his work on the “Birds of the West of Scotland.” Subsequently Mr. Gray entered the Bank of Scotland, and at the time of his death occupied the position of its chief cashier. Since his residence in Edinburgh, he has taken a prominent position in the scientific institutions of that city, and was a Vice-President of the Royal Society of Edinburgh, and Secretary of the Royal Physical Society. He did not become a member of our Society until 1884, but has been long known by several of its members, and highly valued as a correspondent or friend.

The only other member of this Society whose death we have to deplore is Captain Philip Hamond, who has for some time left this city, but who will be well remembered as having resided for awhile at Mousehold House, Thorpe. He showed much interest in the natural history of Norfolk, and also in its antiquities; and he left a valuable collection of books relating to Norfolk.

During the past session we have had many valued papers contributed to our Society; besides some notes – shorter, but not necessarily less interesting, or of less value.

We have also had several specimens exhibited. And, in addition, we have had a considerable number of members who have taken part in the various discussions.

I need scarcely remind you how varied these contributions have been; and how birds, beasts, fishes, insects, and smaller creatures; as well as seeds and plants, great and small; have all received illustrations during the year. Distant parts of the globe, too, have helped to supply us with the material which has been brought before us, notably by our late President, Colonel Feilden.

Many of the papers will be published in the forthcoming “Transactions” of the Society; and to these I need scarcely allude, as they can all be read by us very shortly. But I should scarcely like to omit to mention the beautiful botanical specimens exhibited by Mr. Long, of Wells, at our last meeting. The rarity and interest of some of them, the beauty and finish of the mountings, and the true scientific intelligence displayed in all, can but make us desire that so competent a collector would not only further explore his district, but also enrich this Society by the exhibition of the fruit of his researches.

As to the contributions which will not appear in our “Transactions”: – At the May meeting, Mr. F. Sutton read some interesting notes on Strawberry growing. In October, Mr. Southwell read extracts from the records of the Whaling s.s. “Eclipse” in the Greenland seas. Mr. Southwell’s notes referred more particularly to the natural history occurrences of the voyage; the birds and animals met with. And he exhibited several forms of Whale and Seal food, consisting of Crustacea and various minute organisms; as well as the skulls of two Greenland Seals, two Ringed Seals, and a Polar Bear, sent him by Mr. Robert Gray – all which latter he has presented to the Norwich Museum. He also exhibited a very rare little fish of the genus Scopelus, likewise taken by Mr. Gray.

At the same meeting, our most valued and efficient member, Mr. Geldart, read a paper on the Calanus finmarchicus or Rice Food of Whales, from the West Coast of Spitzbergen, and illustrated by it the natural law of gradation in feeding, showing that whilst some Whales themselves eat this food, others devour the Cod and Herring, which eat these little crustaceans, which again eat the diatoms, found floating in such enormous numbers on the surface of those seas.

My own humble contribution to the proceedings of our last meeting, in the shape of a paper on the habits of some of our town birds, entitled “My Christmas Garden Party,” has been recently published in extenso, and therefore need not be further alluded to here.

There has been only one Excursion made during the year, but this appears to have been full of interest and enjoyment. I have received a lively and detailed account of the day’s proceedings from Mr. Bussey, but I regret that time only permits me to note the principal features of the occasion.

The visit was made to the Salhouse and Wroxham Broads, and the neighbouring district, including the Broomhills, St. Benedict’s Abbey, and portions of the river Bure. It is unnecessary to say how ample is the material in this district for the study of both the animal and vegetable kingdom; and as the day was fine, the opportunities afforded were fully availed of. As usual, this occasion for field study fully repaid those who took part in it, for their devotion of the day to this pleasant combination of research and recreation.

The field over which “Natural History” extends is a very wide one, and properly includes the study of all organised beings, living and dead. At one end the ground is, to a very considerable extent, occupied by the Geological Society, which exists in Norwich; yet even in this department we have had, as I have said, some very valuable contributions during the year. But at the other end, which embraces the study of minute or microscopic life, not only have we had no contributions during the past session, but I find, on looking over the past numbers of our “Transactions,” that the papers dealing with this part of the world’s life have been both few and far between. There have been, as we know, some great and valuable exceptions, such as the papers read by Mr. Kitton, the address by Mr. Plowright, a portion of the address read by the President, Mr. Sutton, two years ago, and, perhaps, one or two others. Still the small part which microscopical records and observations play in our annals is both noticeable and regrettable – the more so, because in consequence of the decease of the old Norwich Microscopical Society, I believe that no public or systematic work in this direction is now being carried on in this city. And yet, partly in consequence of the larger forms of life having now been so largely studied, but still more in consequence of the new views as to the universality and far-reaching importance of microscopic living beings – there is probably no phase of natural history which is now more engaging general attention, or which is being more eagerly studied and investigated elsewhere.

Mr. Sutton, in his presidential address of 1884–85, gave a most learned and interesting description of some of the microscopical researches which had been carried on up to that time, and further gave us a most lucid account of the influence which micro-organisms had been shown to exert in the process of nitrification in soils, an influence which had formerly been considered to be due to purely chemical action.10

I trust I may be forgiven if I recall your attention for a few moments to this subject of Germ life, more particularly as it branches out and develops in a more vital direction; in other words as it affects human and animal life.

This portion of the subject has, during the past two or three years, deepened and strengthened in interest; our knowledge of it has largely increased; and the recognition of its vital importance has called forth, both in Europe and America, a host of eager and capable workers. It is scarcely too much to say that its wide and far-reaching issues are probably the most important to mankind of any that have been studied in recent times. Foremost amongst the workers in this department may be recalled to you the well-known names of Koch and Pasteur, abroad; and of Lister, Watson-Cheyne, and Crookshank, in this country. But the names of other eminent investigators will almost necessarily occur to your minds.

It has long been known what potent factors were microscopic Germs in producing changes in the constitution of decaying matter; and how they were, in all probability, the useful scavengers of nature, definitely resolving into their constituent elements failing and dying organic tissues. But it has become more and more a matter of knowledge, that by their parasitic habits and their power of invading and living upon and within other living tissues, they are also the sources of many so-called diseases of both vegetables and animals.

With regard to vegetable parasitic growth I will not now detain you. The blights, and the mildews, and the ergots, as well as minuter forms, such as algæ and micrococci, are well known; and no doubt much more is still to be learned from their further investigation; whilst by analogy it seems highly probable that the circulating fluids of higher members of the vegetable kingdom may be found to be invaded by parasitic beings in the same way as their animal compeers.

But it is to Germ life in animal bodies that I wish now specially to allude. I have said that our knowledge in this direction has, even in the last two or three years, made enormous strides, and it is now almost a matter of certainty that all contagious or infectious disorders, as well as many others, are but the expression of the fact that minute living bodies have made a resting-place for themselves in or upon other living tissues; and that the development of the phenomena of these morbid states is but an indication of their presence and reproductive activity – either as cause, or as an accompaniment of these disease manifestations. And this applies not only to the human species, but to lower classes of animals, between whom and man many of these diseases are interchangeable.

Such knowledge necessarily invests the life history of these minute Germs with intense interest, seeing that it is probably one step, and that a long one, towards the discovery of the means of prevention, if not also of cure, of many of our most fatal and dreaded diseases.

Examples of such diseases are: – Scarlet Fever, Diphtheria, Small Pox, Cholera, Yellow Fever, Tuberculous Disease, Ague, Hydrophobia, Cattle Plague, Anthrax; and many others might be enumerated whose dependence upon parasitic Germs is almost conclusively proved. But these are sufficient to show the deep interest of this branch of study.

Not only are these Germs found in the solids of the body in some of these diseases, but in others their presence is easily and constantly recognisable in the blood or other fluids, and even within the corpuscles which the blood so largely contains. And not only so, but the forms which these micro-organisms present are so constant and so definite in the different disorders, that it is now almost possible in some instances to diagnose what diseased condition we have to deal with by an examination of the fluid or tissue in which they are contained.

It is, perhaps, but right here to say that some of our most cautious observers consider that it is as yet hardly proven that the differing Germs found in the various diseases are their actual and efficient cause; but their definiteness in the various disorders, and the constancy of their presence, leave little doubt that this will hereafter be conclusively shown to be the case.

Some of these Germs seem to have a short life and rapid development, and then we have acute disease. Others seem to have a more prolonged or continuing career, and then we have chronic disease. Whilst others seem to have an intermitting development, and then we have paroxysmal disease.

Many curious facts have been observed in reference to the forms, or multiplication, or life-history of some of these parasitic beings. Thus, for example, in one class (Filaria sanguinis) it was noticed that the minute embryos of this little blood-worm could only be discovered in the evening or during the night, and not during the day; and the reason of this has appeared to be that it is necessary that they should come within reach of the Mosquito Gnat, which is a night-feeding animal, in whose bodies one stage of their development appears to take place.

One of the latest discoveries in this department of natural history is that of the blood germs, which co-exist with the various forms of ague and malarious disease, and upon which they would appear to depend. Dr. Osler, of Pennsylvania (now Regius Professor of Medicine, at Oxford), has recently described and figured these little bodies in an elaborate paper full of interest.

Such facts as these, when regarded merely from the point of view of a member of the Medical Profession have their deep and special significance. But I am here to-night as a member of the Naturalists’ Society, and by all of us, in that capacity, they are first to be regarded, not as illustrations of disease, but of the life history of some of nature’s creations – creations which are no doubt as important, as definite, and which play as large a part in the general scheme of life, as do many of the larger forms of animated beings.

Some of these little bodies, especially those of the bacillary and bacterial class, are extremely minute, and are best examined with powers ranging from one-tenth to one-twenty-fifth of an inch; and it is impossible to ignore the fact that their study requires not only good instruments, but much patience and skilled attention. Nevertheless, such study fairly comes within the scope of this Society’s work, and will most certainly repay any of its members who may be induced adequately to undertake it.

Nor let it be said that minuteness is any reason for lack of interest on the part of the naturalist. For many of these micro-organisms have already been shown to be as varied, and to have as definite a structure, and as special a life history, as any of the larger types of beings; whilst, of course, we all recognise that apparent size is as nothing, that it is a mere accident, a question of the construction of our enquiring eyes, a condition that is at once altered and rectified by a magnifying glass.

If it be true that the invasion and presence of various small organisms in the blood or tissues is the cause of the various specific diseases to which I have alluded, then the application of such knowledge as naturalists can obtain, as to the food and other conditions necessary to their existence; their mode of ingress to the body; their development and multiplication, becomes clear and obvious. It opens up to our minds possibilities both of prevention, and of either mitigation or cure. For it is evident that if we can starve these Germs of their necessary nutriment, or make their new habitation unsuitable for their healthy and vigorous development, their career as invaders will necessarily either be cut short, or be rendered feeble and impotent; and therefore the disease-changes which they can produce less violent and less lethal.

Something of this kind appears naturally to have taken place in those persons in whom some of the zymotic diseases (of which Measles, Scarlet Fever, Whooping Cough, etc., may be taken as familiar types) have once run their course; in those, that is, who are popularly said to have already had these diseases. And although the exact abiding change which is produced has not been ascertained, yet it is well known, and quite understood, to be one which renders the fluids or tissues partially or wholly unsuitable for their future healthy growth.
