Evidently this is a question of as raucli practical im- 

 portance as it is of profound scientific interest, and it is 

 a question wliieli both men of science and Ijreeders are 

 alike agreed should, if possible, be settled without further 

 delay. 



By way of making nn attempt in this direction I am 

 anxious to organise an extensive series of experiments^ and 

 my chief object in writing this paper is to enlist the interest 

 and co-operation of breeders and otliers in a |)Osition to 

 render assistance. 



I pro]jo.se to repeat as exactly as possible Lord ^Morton's 

 experiment, using, however, a zebra in place of the now 

 extinct quag'ga. I hiive already obtained a number of 

 mares, but as, according to Eomanes, telegouy may only 

 occur in a very small percentag'e of cases, I shall be glad to 

 hear fr(jm any i_iue who is willing to place a suitable mare 

 at my disposal. But in addition to crossing the horse and 

 zebra, it is most desirable that experiments be made with 

 cattle, sheep, pigs, dogs, &c., of various breeds. 3Iay I 

 venture to appeal to those sufBcientl}' interested in the 

 Cjuestion who happen to be in a position tliat admits of 

 their taking part m the work to communicate with me, so 

 that the necessary arrangements for further experiment 

 may be made. In the next number cif this Journal I shall 

 give a list of the experiments which I think might be 

 started during the present season.

In the paper on Telegouy published in the April 

 number of Tin: VrterinaHan. after quoting in full the now 

 famous letter of Lord Morton, I especially referred to the 

 views of Darwin, Herbert Spencer, Agassiz, Eomanes, 

 and ^Veismann. Since this paper appeared I have had the 

 opportunity of reading the recently published work on
