DEPARTMENT OF EMBRYOLOGY.* 



Franklin P. Mall, Director. 



The second year of the work on embryological research has been 

 continued along the Hnes laid down in the report on embrj^ology as 

 given in the Year Book for 1913. Only towards the summer of 1914 

 was the staff increased by the appointment of two additional research 

 associates as well as several members of the technical staff. The emi- 

 nent embryologist, Professor Franz Keibel, director of the Anatomical 

 Institute at Strassburg, was appointed Research Associate on April 1. 

 The plan was that he would cooperate with us in continuing the work 

 as expressed in the Manual of Human Embryology, and arrangements 

 had been made for a conference with him at Heidelberg on August 2. 

 The European war, however, prevented this meeting, and, of course, no 

 report can be expected from him at this time; nevertheless, our plans 

 have been worked out with such detail through correspondence that 

 for the present we can go on working independently. 



During the year we were fortunate in securing the services of Dr. 

 George L. Streeter, professor of anatomy at the University of Michigan, 

 who is well known in connection with his studies on the development 

 of the nervous system. Professor Streeter will continue this work 

 under favorable conditions with us at Baltimore. He received the 

 appointment of Research Associate on July 1. 



A year ago many inquiries were made among leading anthropolo- 

 gists for a suitable investigator, preferably an anthropologist, to make 

 a biometric study and measurements of our human embryos and 

 foetuses. On the recommendation of Professor Schlaginhaufen, of 

 Zurich, one of his students, Dr. Michael Reicher, also a pupil of Pro- 

 fessor Martin, was appointed our collaborator on February 1. Dr. 

 Reicher undertook his task with great enthusiasm, and during a period 

 of six months made standard anthropological measurements of the 

 body and head of most of our foetuses and of many of the embryos. 

 He has also measured a large number of specimens in other collections. 

 The first part of Dr. Reicher's work is partially completed, but as he 

 was beginning to arrange it for publication, the war in Europe made it 

 necessary for him to return to Russia. He has left all of his data with 

 us and, as soon as he is released from military duty, will return to 

 complete the task he has undertaken. 



On April 1 C. H. Miller was appointed technical assistant, and on 

 June 1 O. 0. Heard, a skilled pattern-maker, was selected as modeler.
