 in your former volume, was written, I have

 that plant ; but I only mean at preient to corred 

 one erroneous opinion I had adopted from the refult 

 of thcftngU experiment I had then made with regard 

 to the raifing potatoes from feed. I at that time 

 thought it probable that no new varieties could be 

 thus obtained, and doubted whether a mongrel 

 breed could thus be produced, like that which may- 

 be obtained at pleafure from different varieties of 

 turnips, cabbages, &c. I am now, however, con- 

 vinced, from an experiment that was condudled 

 •with greater care, that there are plants which do 

 produce varieties from feeds, greatly different from 

 the parent (lock; that thele varieties are not of the 

 nature of mongrels, but are altogether din:in6l frorfi 

 any forts that may have been knownj and that the 

 potatoe belongs 'to this clafs of plants.
