 of the Henley potatoes, at that early feafon, are 

 much better to the tafte than thofe of the other 

 kind, although the cafe is afterwards in fome mea-

[This is one proof of the very great benefits that 

 would accrue to agriculture, by an accurate experi- 

 mental attention to circumftances.] 



It has been alledged that potatoes, which have 

 been long propagated by means of bulbs, lofe in 

 time their generative quality, fo as to become much

 has been adopted without fufficient examination. I 

 attended particularly to this circumftance in my

 from feeds, but rather the reverfe.
