CARE AND UTILIZATION OF THE COLLECTION.

with their effort, believing it was possible to produce a better work. Before this 

 could be done, however, it was deemed necessary to organize our forces more 

 thoroughly, and to bring this about a plan for the study of human embryology 

 was drawn up by one of the editors 1 , which embraced the following features: (1) 

 Much larger collections must be made; (2) much better histories of the various 

 specimens must be obtained; (3) the necessary material must be placed at the 

 disposal of the most competent investigators. 



This plan received the full indorsement of leading embryologists, including 

 Keibel and Waldeyer, and was presented to the officers of the Carnegie Institution 

 of Washington, who responded generously with an initial grant of $20,000 to carry 

 on the work for one year as an experiment. At the end of that time a department 

 of embryology of that Institution was established. The Department of Publica- 

 tions of the Carnegie Institution has been of the greatest value to us in our work, 

 for it publishes adequately certain studies which, on account of their expense, 

 could not appear in the journals. These publications, known as the "Contribu- 

 tions to Embryology," are brought out in series at irregular intervals. The first, 

 "On the fate of the human embryo in tubal pregnancy," fills an entire volume. 

 The individual papers appearing therein since then will be found in the appended 

 bibliography.
