[By A. F. M. D. F. R. S.] 



Gentlemen, 



THE attention, which you have defervedly be- 

 flowed on the iubjecl of rhubarb, induces 

 me to believe that a few additional obfervations, 

 which have occurred to me fince my laft,* may not 

 be unacceptable, particularly to thofe who wifh to 

 improve the culture and management of the plant 

 in this country. 



Mr. J. R. Foster, in his hiftory of cc Voyages 

 <f to the North," very lately publilhed, informs 

 us, from the mofl authentick accounts, that at 

 Suchur, a province fubject to the Great Khan of 

 Tartary, where the true plant flourimes in the 

 greater!: abundance, and from whence the merchants 

 carry it all over the world, the country is rocky 

 and mountainous, the foil red with a ftratum of 

 ftone under it, fometimes boggy, being every where 

 interfered with numerous rivulets.
