ary 28, 1910. 
The records of autopsies made in the Laboratory are given 
in table form below. Heretofore it has been the practice to 
enumerate the number of animals showing the various path- 
ological conditions, under main headings of the respective 
anatomical tracts. The present report has followed the 
zoological classification and will show how many times the 
various pathological diagnoses were made in each order. 
The whole number in each class and order is also given. The 
method of classifying the pathological diagnoses adopted in 
the past has been used. All diagnoses are listed for pur- 
poses of record. All conditions noted are not among the 
causes of death, but are of etiological importance, or in the 
nature of sequelse.
