this position he was able to devote most of his spare time to the study of the marine zoology of Otago Harbour. From the point of view of a naturalist these were fruitful years, but there was no outlook for a man of his tastes and ambitions in the primary school branch of the teaching profession. It was the subject of much cogitation between himself and his devoted wife that ultimately led to his decision to throw up his position and devote himself to medicine as a career offering a wider field. It was a very courageous step to take, for it meant at least four years of work without earning, and a sacrifice of much previous effort and progress. But the decision was taken, and in 1895 he entered on his medical studies in the University of Edinburgh. This meant four years of strenuous work, but he was awarded prizes in Botany, Surgery and Physiology, and in 1898 gained his degree of M.B., C.M., with honours, and also won the Aitken Carlyle scholarship. He had all along resolved to specialize in his medical work, and he devoted himself especially to the study of diseases of the eye, ear and throat. In the following year he was house surgeon in the ophthalmic ward of the Royal Infirmary, Edinburgh, and in 1900 studied diseases of the eye at Heidelberg, Vienna and London.

On returning to New Zealand at the close of that year he wisely resolved to select his own city of Christchurch as his field of operations, and commenced practice as an ophthalmic surgeon early in 1901. At this time Dr. Dendy was Professor of Biology in Canterbury College, and having got a year's leave of absence, he got the Board of Governors to offer Dr. Chilton the position of locum tenens. Before the opening of the next session Dr. Dendy had accepted the position of Professor of Biology in King's College, London, and the Board appointed Dr. Chilton to the office thus vacated. He occupied the chair of Biology and Palaeontology till 1910, and from thence till his resignation, in 1928, the chair of Biology.

In 1915 he and Mrs. Chilton lost their only son (and child) Frank, a young man of great promise, who was killed in action on June 4th on the Gallipoli peninsula. He was a second year medical student at Edinburgh University, enlisted on the outbreak of war, obtained a lieutenancy in the Argyle and Sutherland Highlanders and was sent out to Gallipoli attached to the Hampshires. His parents faced their loss with heroic fortitude. In 1921 Dr. Chilton was appointed Rector of Canterbury College, being the first to hold that position in any New Zealand or Australian university college. He resigned it in 1928. In recognition of his 26 years' service as Professor and Rector, Dr. Chilton was awarded the title of Professor Emeritus of Canterbury College at a meeting of the Board of Governors held in April, 1929.

During his professorship the Canterbury mountain biological station at Cass was established, where practical work in the field yielded profit and pleasure alike to teachers and students. All throughout his life he had devoted much attention to the encouragement of education. He was a member for several years of the committee of the West Christchurch District High School, a member of the Canterbury Education Board, and a member of the Board of Governors of Canterbury Agricultural College, Lincoln, and chairman of that body in 1927. Many of those who were long associated

with Dr. Chilton have spoken with appreciation of his work as an educationist. One reference may be quoted here; Dr. Hilgendorf said of him:—“I have never known a man who turned with such understanding and with such effect to the young; his influence in this direction was very great and no student or worker who had even the slightest connection with him but had felt that influence. Many have been guided by his wisdom and many have been inspired by his encouragement to carry on and complete their work.”

Dr. Chilton's scientific researches were chiefly devoted to the Crustacea, and even in this group he wisely resolved to confine his work to the larger forms—specializing particularly in the Amphipoda and Isopoda. A few workers have worked over the whole field of this interesting class of animals, notably the late Dr. G. O. Sars of Christiania (Oslo), Norway. But most have found it the wisest plan to specialize. As already indicated, much of Dr. Chilton's inspiration was due to the teaching and example of the late Professor F. W. Hutton, who was not only an enthusiastic naturalist but a most generous and unselfish worker. The student in such a specialized line of research as the Crustacea is working a lone furrow as far as local co-operation and assistance is concerned. Dr. Chilton's earlier work in this field was largely carried on in collaboration with the writer of this memoir. But after his return to New Zealand he was in touch with workers in other parts of the world and thus broadened his researches and experience until he became a recognised and trustworthy authority in his special groups. His first scientific paper, entitled “Additions to the New Zealand Crustacea,” was read before the Canterbury Philosophical Institute on 13th Oct., 1881, and was followed by one on 3rd Nov., “On some Subterranean Crustacea.” The discovery and description of these well-shrimps from Eyreton fully opened his eyes to the fascinating research on which he had entered. In 1881 he became a member of the Canterbury Philosophical Institute, and these first papers, published in Vol. 14 of the Transactions of the N.Z. Institute, were the forerunners of a series which lasted till 5th Nov., 1924, when his last paper (printed in 1926 in Vol. 56) was read before the same society. Altogether he contributed 51 papers to the Transactions.

His first foreign paper “On a Marine Species of Philougria” was printed in 1884 in the Proceedings of the Linnean Society of New South Wales, Vol. 9, and this was followed by a great list contributed to some twenty different journals and societies. Among the most important of these were papers on “The Subterranean Crustacea of New Zealand,” in the Transactions of the Linnean Society, Vol. 65; “The Amphipoda of the Scottish National Antarctic Expedition,” printed in the Transactions of the Royal Society of Edinburgh, Vol. 48; and on “The Fauna of Chilka Lake,” in Memoirs of the Indian Museum. His contributions to zoological knowledge were published in New Zealand, Australia, Great Britain, India, the Malay States, Holland, Germany, Sweden and the Philippine Islands.

His association with learned societies commenced in 1881 when he joined the Canterbury Philosophical Institute. He was elected President in 1903, 1904 and 1913. He became also a member of the Board of Governors of the New Zealand Institute, first as represen-
