DEPARTMENT OF EMBRYOLOGY.* 



Franklin P. Mall, Director. 



The facilities of the Department were materially increased by the 

 acquisition, in October 1916, of additional floor space in the new 

 Hunterian Laboratory, erected by the Johns Hopkins University 

 adjacent to the present Anatomical Laboratory. The building is of 

 fii'eproof construction, and one floor of it, consisting of over 6,000 

 square feet, was especially designed for the purposes of this Department. 

 In addition to four large rooms, wliich are used respectively as library, 

 room for microscopical technique, machine shop, and modeling room, 

 there are ten smaller rooms for investigators and assistants, a basement 

 room, three dark rooms, and a commodious vault for the preservation 

 of valuable specimens and records. The rooms are well equipped with 

 instalments, glassware, and optical apparatus suitable for embryo- 

 logical investigation. Parts of the larger photographic apparatus were 

 constructed in this country especially for our work. 



After securing these new quarters the space previously occupied by 

 the Department in the Phipps Clinic was relinquished. I take advan- 

 tage of this opportunity to express our obhgations to Professor Adolf 

 Meyer, of the Phipps Psychiatric Chnic, and to Dr. Winford H. Smith, 

 superintendent of the Johns Hopkins Hospital, for their cooperation in 

 providing us with temporary shelter. 



Since my last report the following jjersons have been added to the 

 staff or have undertaken work independently in connection with the 

 Laboratory : 



Last autumn Dr. Adolf H. Schultz, of Zurich, became a member of 

 our staff to continue the work of Dr. Reicher, who returned to Russia 

 at the beginning of the war. Like Dr. Reicher, Dr. Schultz has been 

 trained by Professor Schlaginhaufen, and is therefore well quahfied 

 for the study of the human embryo from an anthropological standpoint. 

 For the past year and a half Professor Kimitomo, professor of anatomy 

 at the Medical School of Nagasaki, who is abroad at the direction of 

 the Government of Japan, has been here investigating the develop- 

 ment of the spinal cord and cauda equina in human embryos. He is 

 now preparing his studies for pubhcation. In May 1917, Dr. Arthur 

 Meyer, professor of anatomy at Leland Stanford Junior University, 

 began work upon normal and pathological embryology in collaboration 

 with me. Professor Meyer is on leave from his university for a year 

 and a half and while with us will rank as Research Associate. On 

 September 1 Miss Jane H. Ross assumed her duties as Research 

 Assistant. Dr. Theodora Wheeler has been studying certain specimens
