obtained when alcoholized males were paired with normal 

 females. The proportion of surviving- individuals is, 

 however, less from the treated females than from the

 9 of which died soon after birth and 10 survived. Thus 

 out of 28 full term young only 10, or about 36 per cent., 

 survived, while 64 per cent, of the offspring were lost; 

 in the above cases where the male alone was alcoholic 

 almost 48 per cent, of the full term young survived.
