CARNEGIE INSTITUTION OF WASHINGTON. 



The collection of human embryos has been greatly increased, largely 

 as the result of a circular, written by Professor Herbert M. Evans, 

 which was widely distributed. Many printed history blanks and 

 directions to physicians regarding embryological material were also 

 sent out, thus enabling us to secure better histories of well-preserved 

 specimens. An extensive correspondence with physicians in the Orient 

 has brought us two specimens from China and a few dozen from the 

 Philippines. We have also secured a very young embryo from an 

 American Indian. A preliminary study of these specimens, as well as 

 those from negroes, show that racial characteristics become apparent 

 much earlier than we had anticipated. 



The collection is well housed and catalogued. By means of the card 

 catalogue, which has been begun, it is quite easy to use it as a reference 

 collection. A list of the specimens arranged according to their age 

 and their accession is given in the following table :
