The following table shows similar results obtained by 

 Hodge from carefully balanced experiments with selected 

 dogs. The males were brothers and the females sisters from 

 two unrelated litters of pedigree cocker spaniels. Demme's 

 observations upon men are added for comparison. 



INKU KNCK OF ALCOHOL ON PROGKNY 

 Dogs (Hodge) 



Men (Demme) 



Moderate, nonintoxicating doses of chemically pure alco- 

 hol were fed to the dogs with their meals, and Demme's 

 normal families were not total abstainers. In further study 

 of the human problem Bezzola found that out of 8190 idiots 

 in Switzerland the majority occurred in the wine districts, 

 and that the larger per cent of these were born nine months 

 after the great national drinking feasts. Schweighofer dis- 

 covered a similar relation between stillbirths and the drink- 

 ing festivals of Austria. 



To keep the germ plasm of the nation on the up-grade, 

 free from any injury, taint, or tendency to degeneration, is 

 the most worthy subject for lifelong study by every man
