new bulbs round the old

have 



thing to do with the corol, anthers, ftigmas, and ne6la 



which have long fince fallen ofF, and peri(hed. And laftly, when c\ 

 rant or goofeberry trees lofe their common green leaves, and th 



brades, by the depredation of infe^ls ; the new leaf- buds become fmall 

 d weak, but the corol, anthers, ftigmas, and nedaries, continue to 



flourifli, and the fruit becomes impregnated, though 



lefs fweet 



and of lefs fize from the pericarp and included feed wanting their d

ftamens 



ftigmas, and nedaries fall off, becomes fimply a vegetable uterus, 

 for the purpofe of fupplying the growing embryons with nouriOi- 

 ment, and poffefles a fyftem of abforbent veffels, which brings the 

 fap-juice to the foot-ftalk of the fruit, and which there changes into 

 a pulmonary artery, which conftitutes the brades or floral-leaves, and 



he oxygenation of the air, and con- 

 This blood is coUeded again by 



expofes the acquired j 



them into vegetable blood

for the various fecretions of facch

At the fame time, as perhaps all the vefl>els of trees inofculate, th 

 fruit may become fweeter and larger when the gn

Some florifts have ob 



ferved this circumftance, and affirm that in many 



when th
