While the results show somewhat diminished fertility, it is 

 evident that longer test periods are needed in which to determine 

 the limits of its duration after mating ceases. This work is to 

 be continued with other pens of hens. The preceding table 

 shows the results from each day's eggs. 



FERTILITY OF EGGS OF DIFFERENT SHAPES. 



To ascertain whether the shapes of eggs have any influence 

 on their chick yielding capacities when incubated, 25 very long 

 eggs, 25 short, ball shaped ones and 25 normal shaped ones 

 were selected and incubated in the same machine with the follow- 

 ing results : 



When undertaking this test it was the intention to carry each 

 lot of chicks until their sex could be determined in order to learn 

 whether the shape of the egg bears any relationship to the sex of 

 the chick it may yield. With that aim all of the chicks were 

 banded and recorded. A barn cat had other plans regarding 

 them however, in the carrying out of which one night, the ques- 

 tion of sex was not considered. Other tests bearing upon this 

 subject will be made.
