the drug was given his temperature had ranged from 09*^ 
to 101° F. Immediately after the first dose the temperature 
fell to below 99° and remained at a very regular level during 
the entire twenty days. No malarial organisms were found 
in the blood. 
I take pleasure in acknowledging with thanks the advice 
and assistance of Dr. H. M. Langdon and Dr. Saxon in this 
work. 
Leucocyte Counts Made ix the Garden. 
E. A. Schumann, Herbert Fox. 
The desirabilty of knowing the normal blood conditions 
of wild animals prompted Dr. Penrose to suggest to one of us, 
E. A. Schumann, to count the blood of apparently healthy 
animals. The taking of blood preparations from animals 
is beset with great difficulty, to say nothing of possible injury 
to the animal during its struggles. The few^ notes recorded 
below may serve as a guide to hematologists and biologists. 
AVe do not offer these as final, but merely as percentages of 
leucocytes from high counts in the best specimens of blood 
we could obtain from the respective animals. They are 
grouped according to Zoological classification.
