green leaves ſerve as lungs to the ſhoots and foſter the new buds in their bofoms, whecher theſe buds be leaf-buds or fruit-buds; but in the early ſpring the fruit-buds expand their corols, which are their lungs, and ſeem no longer to require green-leaves; hence the vine bears fruit at one Joint without leaves, and puts out a leaf-bud at another Joint without fruit. And I ſuppoſe the green leaves which riſe out of the earth in the ſpring from the Colchicum are for the purpoſe of producing the new bulb, and its pla- Centa, and not for the giving maturity to the ſeed. When currant or gooſberry trees loſe their leaves by the depre- dation of inſe&s the fruit continues to be formed, though leſs ſweet and leſs in ſize.

7. From theſe faets it appears that the lower-bud af- ter tie corol falls ofl,(which is its lungs,) and the ſamens and nedtary along wich it, becomes imply an uterus for

the purpoſe of ſupplving the growing embryon with nou-

riſhment, together wich a ſyſtem of abſorbent veſſels viich bring the Juices of the earth to the footſtalk of the fruit, and which there changes into an artery for the PUur- poſe of diſtributing the ſap for the ſecretion of the ſac- charine or farinaceous or aceſcent materials for the uſe of the embryon. At the ſame time as all the veſſels of the different budsof trees inoſculate or communicate with each other, the fruit becomes ſweeter and larger when the green Jeaves continue on the tree, but the mature Aowers them- lelves,(the ſucceding fruit not conſidered) perhaps ſuffer lietle injury from the green leaves being taken oft, as ſome foriſts have obſerved.
