An isolation made at the end of the tenth week showed that in 

 the I per cent alcohol line the range of egg production was from 

 1 to 19, with an average of 11.07. This is slightly lower than the 

 results in the fifth week, where the range was from 4 to 22, with 

 an average of 11.25. In the eleventh week the range of life was 

 from 3 to 8 days, with an average of 6.46. In the fifth week the 

 range of life had been from 3 to 7 days, with an average of 5.83 

 days. In the eleventh week in j per cent alcohol the average 

 and maximum production of eggs had fallen below that in the 

 fifth week, but the maximum length of life at this time was the 

 greatest attained by any individual throughout the entire 

 study. A greater length of life under treatment with alcohol 

 was noted by Stockard in one of his guinea-pigs, which lived 

 seven years — an unusual time in that organism. Individuals 

 subjected to I per cent alcohol showed at this time a range in 

 the egg deposit of 1 to 10, with an average of 5; this was the same 

 as the range in the fifth week, but at that time the average was 

 only 3.98. The range of life for this period was from 3 to 7 days, 

 with an average of 5.70 days, as compared with a range of 4 to 7 

 days and an average of 6.09 days at five weeks. In malted 

 milk under normal conditions the range of egg production at the 

 eleventh week was 8 to 29, with an average of 19.70, while the 

 range in life was 3 to 7 days, with an average of 6.48 days. At 

 this isolation, just as in the previous one, there is a decided 

 reduction in the number of eggs produced in both the alcohol 

 lines and very little reduction in the average life-period. 



At the beginning of the fifteenth week two new isolations of 

 100 individuals each were made from the ^ per cent alcohol 

 line; one of these was reared in 1 per cent alcohol; the other in 

 1^ per cent. At the beginning of the seventeenth week isola- 

 tions were made for the determination of the egg production and 

 the length of life from the five lines, malted milk, | per cent, 

 ^ per cent, 1 per cent, 1| per cent alcohol. At this time the line 

 in I per cent alcohol showed a range in egg production of 4 to 22, 

 with an average of 10.80; a range in the length of life of 3 to 7 

 days, with an average of 5.88 days. The line in ^ per cent 

 alcohol showed an egg production ranging from 1 to 10, with an
