When a specimen reaches the laboratory acknowledgment is promptly made, 

 accompanied by a history blank and return envelope. Invariably the physician 

 will fill out and return the blank, and this also is acknowledged immediately. Any 

 request made by the physician is noted and, in the course of time, whatever infor- 

 mation we may be able to give is sent to him. In every case a summary of the 

 description of the specimen is furnished him. 



In tendering our thanks to the many friends who have helped in the up- 

 building of the collection, we wish first to state that it owes its existence primarily 

 to the encouragement given by the great Swiss anatomist, Wilhelm His, whose 

 lively interest in it continued until his death in 1904. From 1889 until 1914 the 

 late Professor Minot also aided us in every way possible, not only in studying our 

 best specimens, but also in donating many valuable pathological embryos. His 

 great collection of vertebrate embryos in the Harvard Medical School was likewise 

 made at the suggestion of Professor His. It will be readily seen by the appended 

 list of contributors that large numbers of specimens have been donated by certain 

 individuals during the past 30 years. The names of Ballard, Boldt, Brodel, Cullen, 

 Hammack, Hunner, Lamb, Terry, Titlow, Trout, West, and Williams appear 

 repeatedly every year. 



One specimen, a negro embryo (No. 460), 21 mm. long, is worthy of special 

 mention at this time. It was obtained from a hysterectomy performed by Pro- 

 fessor Thomas S. Cullen, was brought to the laboratory immediately by Dr. 

 Elizabeth Hurdon, and received alive by Professor Sabin, who injected its blood- 

 vessels, microscopically, with India ink and preserved it perfectly in a corrosive 

 acetic solution. During the two years following, numerous surface drawings were 

 made of this specimen by Professor Evans under the direction of Professor Brodel ; 

 Dr. Essick and Professor Evans cut the embryo into a perfect series; and finally
