PRINCIPLES OF STOCK-BREEDING. 



matozoa come in contact with the ovum to produce 

 impregnation. 1 



At a meeting of the Agricultural Society of Se- 

 verac, on the 3d of July, 1826, M. Charles Girou de 

 Buzareingues proposed "to divide a flock of sheep 

 into two equal parts, so that a greater number of 

 males or females, at the choice of the proprietor, 

 should be produced from each of them. Two of the 

 members of the society offered their flocks to become 

 the subjects of his experiments," a the results of which 

 are given in the following table. 



The principle of division was to place young rams 

 with strong, well-fed ewes, for ewe-lambs, and a ma- 

 tured, vigorous ram with weaker ewes, for ram-lambs. 



The first experiment gave the following results :

 penter's " Human Physiology," p. 967.

 ture Fran9aise," vols. xxxvii., xxxviii., and a summary from which we 

 quote will be found in the Quarterly Journal of Agriculture, vol. i., 

 May, 1828, p. 63.
