 §. VIII. 



Hitherto I have only taken notice of the total 

 weight of the crops but as the value of that crop is, 

 in many cafes, affected by fize of the bulbs, it is 

 neceiTary to attend to thofe circumftances that may 

 tend to increafe or diminifh their fize. With a 

 view to that particular I have, in the preceding ex- 

 periments, recorded the number of potatoes pro- 

 duced in every cafe, as well as their weight. 



It is commonly imagined, that if the feeds planted 

 contain many eyes, the bulbs produced will be nu- 

 merous, but fmall; and that larger bulbs in 

 fmaller number are produced in plants that have 

 only one, or few eyes : hence it is concluded, that 

 whole potatoes planted for feed will always pro- 

 duce a greater number of/mall potatoes j and cut- 

 tings will yield larger potatoes, though fewer than 

 thofe. It does not, however, appear, that this hy- 

 pothefis is fupported by the foregoing experiments. 

 In the average table, §. II. we find that the bulbs 

 produced from the 3d and 4th rows, which con- 

 fided of plants with -one eye only in each, were 

 fmaller, as well as lefs numerous, than thofe in the 

 1 ft and 8th rows, which confided of plants that 

 contained many eyes. On the other hand it ap- 

 pears, from the fame experiments, that the bulbs 



produced
