holic male No. 43 she produced two fetuses which died 

 in utero and killed her. 



Female No. 59, alcoholic, has a similar record and was 

 also finally killed by 3 fetuses dying in utero and poison- 

 ing her. 



Alcoholic females 55, 60, 62 and 66 all show very poor 

 records in the production of viable offspring. 



During the course of the experiments four females have 

 been killed by the death of fetuses in utero. In three of 

 the cases this occurred after the females had been treated 

 with alcohol for a number of months and were becoming 

 more and more affected by the treatment. No. 61 died 

 after she had been given alcohol for four months with 

 three fetuses in utero which had apparently been dead 

 for several days. No. 64 had been treated with alcohol 

 for over one year and finally, while in a late stage of 

 pregnancy by alcoholic male No. 43, she became stupid 

 and refused to eat. On examination the fetuses showed 

 no signs of life and were quite hard ; they were removed 

 by operation and had been dead several days. The 

 mother had become so intoxicated by this condition that 

 she was unable to recover after the removal of the 

 fetuses. 



Female No. 59 had been treated with alcohol for thir- 

 teen months when, after being mated with a normal male, 

 she was operated upon in order to remove three dead 

 fetuses. % She failed to recover. 



The fourth case of young dying in utero was that of a 

 normal female, No. 30, that had been mated with an 

 alcoholic male. The almost full term fetuses died and 

 produced the same symptoms in the mother as those in 

 the cases above; she was also operated upon and failed 

 to recover. 



It is a perfectly easy operation to remove the ovaries 

 or uterus from a normal guinea-pig. I have not tried to 

 remove living fetuses. There is little doubt, however, 

 that it is the accumulated toxins owing to the presence of
