Report of the Laboratory for the Year Ending 
February 28th, 1913. 
The following report is submitted by me as your Act- 
ing Pathologist during the leave of absence granted Dr. 
Herbert Fox. It follows the plan of past years. A list 
of pathological diagnoses is first given, representing the 
routine autopsy findings, both gross and microscopical, 
arranged by systems under the heads of classes and 
orders. The diagnoses, not always the causes of death, 
are listed in full as a matter of scientific record. The 
second section reviews groups of cases and also records 
miscellaneous activities in which the laboratory may 
have been or is engaged. The year has been an active 
one in spite of the suspension of research work during 
the summer months when the laboratory building was 
being altered.
