Fox taking charge of this the following year (Fig. 1). As the opera- 

 tions of this department became more extensive, it was realized that the 

 labor of no one man could properly compass it; therefore, in 1910, Dr. 

 Fred D. Weidman, who at the time was assistant in the department of 

 pathology at the University of Pennsylvania, received the appointment 

 of assistant pathologist, and the following year a second floor was put 

 upon the building to accommodate the museum specimens and for 

 additional work-room. 



From about this time on, the principal part of the report of the 

 society was given over to that of the pathological laboratory, a most 

 gratifying indication of the value of the work performed there. As 

 evidence of this we find that the thirty-ninth annual report of the 

 board of directors of the society (1911) prints forty-seven small octavo 

 pages, and of these Dr. Fox's report of the laboratory occupies from 

 pages 15 to 40 inclusive. 



Far-reaching in its importance, this report contains most valuable 

 data, which can not fail to be of use, not only to keepers of gardens and 

 menageries, but to the human pathologist and the breeder of domestic 

 animals. The report goes to show that no fewer than 325 animals were 

 examined, of which number 93 were mammals. There is an excellent 

 report on " Tuberculin Eeaction in Monkeys " containing much of prac- 

 tical value, while what Dr. Weidman gives on " Parasites " is not only 

 quite extensive, but presented in great detail. A valuable special report
