No. 563] EFFECT OF INTOXICATING MALE PARENT 667 



holic male No. 5 an apparently normal guinea-pig was 

 born; mated with No. 43, an alcoholic male, she gave 2 

 young which only lived for two days ; then mated again 

 with a normal male she produced 2 vigorous offspring and 

 finally mated with No. 69, an etherized male, 2 young 

 were born, one of which died at birth. Thus, out of the 8 

 matings, 2 with normal males gave perfectly normal off- 

 spring, while 5 out of the 6 matings with treated males 

 gave disastrous results and only one of these matings 

 resulted in the production of an apparently normal young. 



Number 56, a normal female, mated to a normal male, 

 No. 48, gave 2 normal young ; with alcoholic male No. 45 

 gave 3 premature stillborn fetuses; again to a normal 

 male No. 80 gave 3 normal offspring ; and finally again to 

 alcoholic male No. 45 she gave one very small young. 



Normal female No. 63 gave two normal individuals by 

 a normal mating and then three successive matings with 

 an alcoholic male failed to produce a viable offspring; 

 one mating resulted negatively, one gave three young 

 dying shortly after birth, and in the third case two late 

 fetuses were aborted. She was then mated again to a 

 normal male and produced two vigorous offspring. 



Normal female No. 50 was mated alternately with 

 normal and alcoholic males for 4 matings, with alter- 

 nately good and bad results. 



Animals 19, 30, 54 and 58, all normal females, show 

 records closely similar to the ones just mentioned. (In 

 a former table of successive matings the first mating of 

 No. 19 has been recorded incorrectly ; it should read by a 

 normal male giving two normal offspring as in the pres- 

 ent Table II, instead of by alcoholic male No. 4 with a 

 negative result.) 



Alcoholic female No. 64 gave two normal young by a 

 normal male before her treatment was commenced. 

 Mated to alcoholic male No. 6 she gave two young; one 

 died at birth and one survived ; with alcoholic male No. 5 

 she gave an apparently normal young; finally, by alco-
