One of the 23 families in lot Hi from H laid 14 eggs, of which 

 11, or 78.5 per cent, hatched. From the first of her 11 daughters 

 a parthenogenetic line was reared, as in table 36, including 35.8 

 per cent of male-producers. 



Lo from H. Females of the parthenogenetic line Li from H 

 were mated with males of the same line June 9 to 17, 1912. 

 From eight such females were obtained 65 eggs, of which 36, 

 or 55.3 per cent, hatched prior to July 1 (table 37). 



H2 from H. Females of the parthenogenetic line H^ froin H 

 were mated with males of the same line June 8 to 13, 1912. 

 From 23 such females were obtained 164 eggs, of which 92, or 

 56.0 per cent, hatched prior to July 14 (table 38). 



Comparison of L^ from H with H2 from H indicates that a 

 second selection for high and low viability within the high 

 viability series had no effect.
