We have fent for your infpeftion two fpecimens of fome 

 raifed in Scotland on the eftate of the Duke of Athol, 

 which are produced from the true Siberian kcA. The 

 Duke fent us fome the fame as the fpecimen No. II. lail 

 year, upon wluch we took the opinion of fome gentlemen 

 of the tirft eminence in the profelhon, (the fame with whom 

 we have confulted refpe£ling yours;) they agreed, that jt 

 was nearly if not quite equal to the Ruffian, in fmell, tafte, 

 and effect, but thought, by paying a little more attention 

 to the curing of it, its beauty might be increafed. We re- 

 prefented this to the Duke, and he has now fent us a fpe- 

 cimen (of which No. I. is a part) of what we are to have 

 in future. As yet we have not received any of it for fale- 

 but of No. II. have fold a large quantity, which has been 

 generally approved by the gentlemen who have ufed it. 



We hope this account will prove fatisfa£tory to the 

 Gentlemen of the Society : fhould they wifli any further 

 trials to be made, and can favour us with any larger fpe- 

 cimens, we will get them ufed in every form of pharmacy, 

 and the different menftma. 



We (hall always be ready to give the Gentlemen our 

 fentiments on any fubjedl that may come before them, 

 wliich relates to our line of bufinefs. 



IVe have the honour to remain. Sir, 



Your obedient humble fervants, 



CLARKE, JACAM, and CLARKE.
