As the operations 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.

There is an excellent report on "Tuberculin Reaction in Monkeys" containing much of practical value, while what Dr. Weidman gives on "Parasites" is not only quite extensive, but presented in great detail.
