A. In tlic Treated Individuals. 



Before entering upon any discussion of the efifect of the alcohol 

 treatment on the progeny it seems desirable to examine with some 

 care into the effects, both structural and physiological, upon the 

 treated individuals themselves. In this examination attention will 

 be confined to characters which are capable of quantitative definition 

 and measurement. The main results are summarized in Table I.

The plan of this table is as follows : In the last column of the 

 table a plus sign denotes that, with reference to the particular charac- 

 ter discussed, the alcoholists have been favorably affected ; a minus 

 sign that they have been unfavorably affected as compared with 

 untreated controls. A zero indicates that no effect of the treatment, 

 one way or the other, has been detected. 



From these summarized data it is possible to gain a tolerably clear 

 comprehension of the objective happenings in these experiments so 

 far. The treated animals themselves are not conspicuously worse 

 or better than their untreated control sisters or brothers. The sur- 

 vivors, i. €., those not killed by accident, are after roughly a year 

 and a half of daily treatment, becoming a bit too fat for their best 

 physiological economy, but except for that point, and the reduced 

 activity which goes with it, they are very much like normal fowls.
