INFLUENCE OF SEASONS ON INSANITY-EATE 



281 



If now, instead of considering insanity in general, we examine the 

 movement of the rate of alcoholic insanity in particular, we shall 

 find that the maximum is likewise attained in June, and that 

 this maximum is followed by a regular decrease until December. 



Table H. — Statistics showing the Influence of Seasons on the 

 Rate of Alcoholic Insanity. 



The rate of increase from January till June fluctuates slightly 

 from month to month, but the result is an increase from 151 

 cases in January to 250 cases in June. The rate of decrease 

 from June to December is absolutely regular. If we examine 

 for the four quarters of the year the variations in the rate of 

 alcoholic insanity we come to the following result : 



Thus we find the quarterly maximum occurs in the second 

 period of the year, during the closing month of which the monthly 

 maximum of the rate is reached.
