other country. The wool, therefore, which is there pro- 

 duced, will not only be fine upon the whole, but of a 

 more uniform texture and Ilrength throughout than other 

 wool *. 



The 



* What is here Lid, does not cxacflly coincide with the opinion of 

 Mr. Le Blanc, as exprefled in Appendix, No. I. It is eafy, however, to 

 account for this feeming difcrepancy, in a way that, it is hoped, will prove 

 fatisfacftory to the reader. 



The facfls here flated have been afcertained in the mofl undeniaLiIe man- 

 ner, by repeated experiments, which are particularly detailed in the per- 

 formance quoted above, but which it is judged unnccelTary here to re- 

 peat. 



But Mr. Le Blanc having never, in all probability, heard of thefe ex- 

 periments, and having obferved the flriking effedls produced on his flock, 

 by the introdudlion of another breed of fheep among them, though no 

 ' change on the climate had taken place, ver^' naturally inferred that the 

 climate was not to be regarded in any attempt to improve the quality of 

 the wool. 



The writer of this article has alfo, from his own experience, found, 

 that the climate has no efFecfl whatever in altering the /ii'/waw«; finenefs 

 of the wool of fheep ; and that this can only be effected by an alteration 

 in the parent ftock. But his experiments are, at the fame time, clear and 

 decifive In proving that any confidera'ole alteration in the climate, with 

 refpedl to heat and cold, has a great and irrefiflablc temporary cffcdl: in al- 

 tering the fincnefs of the wool, as is flated above ; and thefe experiments, 

 when thev Ihall be repeated by Mr. Le Blanc or others, he is confident, 

 will not fail to operate convidion. 



That his meaning here may be clearly underflood, he begs leave to ob- 

 ferve, that by a permanent change is here meant, fuch an alteration, as that 

 when this new progeny Ihall be ^\?iCcA in the fame circumjlances vfiththz 

 parent ftock, it will always produce wool of a quahty different from that 

 parent flock ; and by a temporary change, muft be underftood an alteration 

 produced on the quality of the wool of the fame animal in particular «»- 

 cumjiances only, and which is of fuch a nature, that when the animal is 

 placed again in the fame circumftances as before, the wool produced then 

 will be of the fame quality as formerly. For example ; when Englifh 

 fheep are carried to the Weft Indies, their clofe pile of wool is changed into a 

 _thin fort of coarfe hair; but if the fame fheep, or their progeny, (if they 

 Jiave pot been adulterated by foreign intermixtiire), be brought back to 



Enc^land^
