VII. HATCHING WEIGHT OF Fi PROGENY 



Cole and Davis (4) found a reduction in the birth weight of 

 rabbits when the father was alcohohc. Cole and Bachhuber 

 (3, p. 25) report a reduction in birth weight of guinea pigs from 

 a lead poisoned father. This result has been confirmed and 

 extended by Weller (42, p. 292) who reports an average reduc-

tion of about 20 per cent in birth weight of guinea pigs from 

 lead poisoned parents. Stockard has given no figures for mean 

 birth weight in his experiments, but the inference from all of his 

 data, particularly that relating to the proportion of dwarfed 

 young, is that had birth weights been systematically recorded in 

 his experiments, the mean would have been distinctly lower in 

 the offspring of treated parents than in those from normal 

 parents.
