various parts of the same system in the chick, to which little has 

 been added subsequently, in spite of the enormous improvements in 

 technique since those days. 



In 1880 Sedgwick was elected to a Fellowship at Trinity. He was 

 still working in Balfour's little laboratory, among his comrades being 

 the late Prof. Mitsukuri, Walter Heape, and Prof. S. J. Hickson. He 

 was also demonstrating to Balfour's rapidly growing classes. An 

 interesting and beautifully complete research was his account of the 

 elaborate kidney of Chiton, practically unknown before. 



In 1882 the University created an extraordinary Professorship in 

 Animal Morphology for F. M. Balfour, but the post became vacant in 

 the same year owing to his untimely death in the Alps. The young 

 school seemed in danger of extinction, but fortunately the University 

 trusted Sedgwick, for whom Trinity created a College Lecturership, 

 really a special contribution from the College towards the needs of 

 the University. A laboratory was at that time being built for the 

 practical teaching of Zoology, but a change in the medical curriculum 

 necessitated an enlargement, so that in 1884 the roof of a neighbour- 

 ing building was bodily lifted by the Engineering Department of the 

 University, giving a room capable of holding upwards of one hundred 

 students, though the actual classes at that time only numbered about 

 fifty. In the same year the University created a Lecturership in 

 Animal Morphology for Sedgwick, which in 1890 was changed to 

 a Keadership. The Department was thus recognized as autonomous, 

 and it continued in the same position, until it became merged in the 

 Department of Zoology in 1907, when Sedgwick succeeded Professor 

 Newton in the Chair of Zoology and Comparative Anatomy. 



Sedgwick's position in 1882 was a difficult one. He was called 

 upon to succeed one of the most brilliant and charming personalities 

 that the science of zoology has known. He was of the same standing 

 as his demonstrators, and he was little older than his students. He 

 was called upon to teach, and subsequently to act as counsellor to, 

 students in all branches of morphology, while his own attention had 

 been almost exclusively devoted to vertebrate embryology. Miss 

 Alice Johnson worked (largely in conjunction with Dr. Gadow) on 

 the development of the vertebrate skeleton, W. Bateson on Balano- 

 glossus, the late Prof. W. F. E. Weldon on vertebrate embryology 

 and Dinophilus, F. G. Heathcote on Myriopoda, and A. E. Shipley 

 on the Lamprey and Gephyrea. S. F. Harmer began that long series 

 of researches which have so greatly clarified our ideas on the 

 Polyozoa. Caldwell, in conjunction with Threlfall, was then perfecting'
