In the second experiment the ewes were divided 

 into three sections. 



The first section included the strongest ewes from 

 four to five years old, which were better fed than the 

 others. It was served by four ram-lambs, about six 

 months old. 



In the second section were the weakest ewes, 

 under four or above five years old. They were 

 served by " two strong rams," more than three years 

 old. 



The third section consisted of ewes belonging to 

 the shepherds, "which are in general stronger and 

 better fed than those of the master, because their 

 owners are not always particular in preventing them 

 from trespassing on the cultivated lands that are not 

 inclosed." These ewes were served by the same rams 

 as section two.

In the first section were two twin-births four 

 females. In the second and third there were also two 

 three males and one female. 



These experiments were considered almost conclu- 

 sive ; but it will be observed that the results are not 

 more remarkable for the range of variations presented 

 in the relative numbers of each sex than were ob- 

 tained in my experience in different years with ani- 

 mals under the same management. 



The number of animals under observation in these 

 experiments is too small to give the results any value
