PROF. I SAO IJIMA, who died of apoplexy in Tokyo on March 14, was born in 1861, and received his training as a zoologist in Tokyo from Prof. C. O. Whitman; and his first papers, on the leech Nephelis, were contributed to the Quarterly Journal of Microscopical Science and Zoologischer Anaeiger (1882). Continuing the study of various worms, he was attracted to the laboratory of Leuckart; but after his return to Japan, about 1890, he began a long series of researches on the beautiful Hexactinellid sponges of the neighbouring seas. In a series of papers published in the Journal of the College of Science of Tokyo University, Ijima threw light on the structure and development of many of these siliceous sponges. On the death of Mitsukuri, Ijima became senior professor of zoology at Tokyo University. Though administrative duties checked the flow of papers, he had prepared the manuscript of a large monograph on the Hexactinellidae, which, it is to be hoped, will soon see the light. Ijima was a good shot, a keen fisherman, an all-round naturalist, and a charming companion. He leaves many friends and a succession of distinguished pupils.
