A medical gentleman fowed laft year two bufhels 

 of fets from one of the above places, and had not 

 one curled -, but on fowing them again this year he 

 had a few. 



N.B. Although the foregoing letters do no| 

 point out with certainty the real or general caufe 

 of the curled difeafe in potatoes, or difcover any 

 Ipecific remedy which reaches all cafes, yet as they 

 contaiii many interefling obfervations both on the 

 difeafe itfelf, and the belt methods hitherto adopted 

 for preventing it, we think they are not improperly 

 introduced in this work. And, notwithftanding 

 there feems to be a diverfity of opinions in the 

 writers, occafioned by the different appearances of 

 their crops, and the feemingly contrary effects of 

 the means ufed to prevent or cure the difeafe, we 

 conceive, that the following general propo/ttiom may 

 he fairly drawn from the whole :-- — 



17?. That fome kinds of potatoes are in the 

 general much more liable to be affe(!:tcd by the 

 difeale than others; arid that the Old Red, the 

 Golden Dun, and the Long Dun, are the moft free 

 from it.
