Skin. Some fmooth as filk, others rough like 

 fhagreen ; fome whole and uniform, others cracked 

 in a variety of diredbions. 



Leaf. Some broad and obtufe, others narrow, 

 fharp and fpur- (haped ; fome fmooth, others rough; 

 fome comparatively gloffy and fhining, others un- 

 even and much wrinkled, &c. 



It would beendlefs to trace out all the other di- 

 \-erfities. In fhort, the variety was greater than I 

 could have conceived to be pofilble ; and there was 

 not perhaps two plants precifely of the fame fort. 



It is probable there will be found to be as great 

 a diverfity in the tafte and other qualities, as in thofe 

 particulars already remarked ; but this I could not 

 fo readily afcertain, 



From the above enumerations, it appears to me 

 inconteflibly evident, that the varieties can be in no 

 fort afcribed to the influence of different varieties 

 producing a compound between them, as in the 

 mongrel breeds. There were many red, bright 

 red, kinds of potatoes, though there was not one of 

 that colour grew in the neighbourhood j and no 

 mixture of white and dark purple could ever pro- 

 duce a bright red, or a dark bottle-green; not to 



mention
