HEREDITY AND SELECTION IN SOCIOLOGr 



If we turn our attention now to the influence of seasons on 

 the rate of general paralysis, we find that the maximum is 

 attained in May, whereas June occupies the second place, 

 slightly inferior to May, which has a total greatly larger than 

 that of any other month. The fluctuations from month to 

 month are more frequent in the rate of general paralysis ; but 

 it is remarkable that the minimum is obtained in the rate of 

 general paralysis, as in that of alcoholic insanity and of insanity 

 in general, in February.

 Rate or General Pabalysis. 



If we examine the quarterly variations of the rate of general 

 paralysis, we find that, as in the case of alcoholic insanity, the 

 quarterly maximum is reached in the second annual period 

 (April to June).
