Anfwers to ^eries from the Bath Socieff 

 rejpe5ting Rhubarb. 



[By Dr. Hope, of Edinburgh.] 

 Gentlemen, 



i.'T^HE Rheum Palmatum is the Turkey, or 

 A RufTia Rhubarb. The India Rhubarb is 

 the root of another fpecies, or variety. 



, a. I believe your obfervation refpedling the root 

 dying at four years old to be well founded; and 

 therefore it fhould be raifed at that age. 



3. I am of opinion, that the entire root Ihould 



be hung up in the open air for two, three, or more 



O 2 weeks^
