These figures suggest: that the normal rate of in¢rease is about 12 per cent. No 
good reason is known for the small percentage of increase in 1914. 
The dead pups were counted at the same time as the live ones. In 1916 the pro- 
portion of dead pups to the total number born was somewhat larger than in previous 
years. No evidence of Uncinaria was seen. Mange, which was observed on a large 
number of pups in 1915, appeared to a lesser extent in 1916.
