TABLE VIII 

 BIRTH V/L16HTS AriD RATtS OF GROWTH OF 

 MORAAAL AND y^LCOHOLIC YOUN6 



The average birth weight of the individual in the normal 

 series is 77.16 grams against 70.35 grams for the alcoholic, and 

 the average litter weight is 27.12 grams heavier among the nor- 

 mal animals. The average weight of the individual in a given 

 size Htter is shown in parentheses below the htter number ; this 

 is obtained by dividing the total weight in grams of all such 

 litters by the total number of animals composing them. For 

 example, in the alcoholic series there are 168 animals born in 

 litters of two and their total birth weight was 13,867 grams, 

 which gives an average weight of 82.54 grams per individual. 

 The average weight of the individual is lower in the large htters 

 than in the small ones in both series. 



The second line of the table shows in a similar way the total 

 weight at the end of the first month of all individuals in the sev- 

 eral-size litters and below this the number of individuals con- 

 cerned in each case. The quotient obtained by dividing the 

 total weight by the number of animals is given in parentheses 

 as the average weight of the individual in each litter at one 

 month old. At this age the average weight of normal animals
