 them, mewed any bio/Tom ; but none of the bulbs, not even 

 thofe from the largeft plants, were nearly of fuch a fize 

 as thofe produced frbm very large potatoes: nor did they

 from old potatoes planted on the fame foil at eighteen 

 inches apart. The facts wifhed to be eftablifhed by this 

 experiment being now afcertained, and I being engaged in 

 other intercfting purfuits, it was not thought neceflary to 

 continue it longer. The following corollaries feem to be

§. II. 



From the accounts I had received of potatoes 

 raifed from feed, it did not appear to me clear 

 whether new bulbs were produced from thefe po- 

 tatoes in the fecond or third year of their growth, 

 or whether thefe potatoes during that time con- 

 tinued only to increafe in bulk, without producing 

 other potatoes from them. It was always faid that 

 they did not attain perfection till the third year from 

 the feed; and what was meant by their attaining 

 perfection, I could not gather from any accounts I 

 had feen. And as it was faid they could be ob- 

 tained by this means much earlier in the feafon than 

 others, and were pofiefled of many other fingular 

 qualities, I could not tell what judgment to form of
