Excerpt from The Biological Bulletin, 1920, Vol. 39 The tabular view of attendance (p. 20) shows a total attend ance of 262 (students 128, and investigators 134) which is twenty greater than the previous largest year This number cannot be exceeded until another laboratory is built. The receipts from students and investigators were in 1919 as compared with in 1916, in 1917, and in 1918. The number of subscribing institutions was 47 in 1919; the largest previous number was 40 in 1916; in 1918 the number was 33.

Excerpt from Biological Bulletin, 1916, Vol. 30 Guyer in his excellent work on the spermatogenesis Of normal and hybrid pigeons says: It is a remarkable fact that no attempt has been made so far to investigate carefully the spermatogenesis or ovogenesis Of hybrid forms. In all the mass of literature discussing or touching upon hybridism, so far as I have been able to ascertain, there has been in no instance an approach to a thorough study of the germ cells. Yet almost every writer states that through the study Of hybrids, we have perhaps the best opportunity for gaining a clew to many of the most vital points in the great problem Of heredity. A number Of investigators have remarked that in certain instances the anthers, ovary, or testes as the case might be, were defective, and have let the matter go at that. It is even more remarkable now, since fifteen years have elapsed and no further attempt has been made to investigate carefully the spermatogenesis or ovogenesis of other hybrid forms. Professor Guyer's work on hybrid pigeons which was published in 1900, the same year in which Mendel's investigations were rediscovered, so far remains as the only outstanding piece Of work on that particular subject. It is all the more remarkable when we consider the fact that such a great deal Of cytological work has been done during the past fifteen years and that by far the largest bulk Of the work on hybridization has been done during the same period.
