Thus, if the above arguments be conclusive (but, from 

 my time being necessarily devoted to business, I have not

 I shall be glad to have it inserted : and shall soon follow

In the early part of the present summer I undertook Ji Quantity of fe- 

 series of experiments, to ascertain the quantity of fecula <="'-' ''*^^^ P*' 

 contained in the seveml varieties of the potato cultivated in ^ ^ ' 

 this neighbourhood, which I take the liberty of laying he- 

 fore the society, for their information, and as a subject well 

 worthy of a farther investigation. 



But as the following experiments were tnade with the Exreriment 

 fre«*i roots, and at a time of the year when most of them ^^^^ ^"|^ 

 were in a growing state, the several results pan be viewed
