^^OF^ 00 SEPTEMBER 7. The young caterpillars are 

 -HETURXEP partial to the leaf they are bred in. Obferv- 

 ing one juft excluded from a leaf which is be- 

 come old, withered, and yellow, with only 

 here and there a green fpeck, 1 cut off the part 

 on which it was feeding (thinking that a 

 younger leaf would be more acceptable) and 

 laid it upon a frefli young plant, in fuch a man- 

 ner that the animal lay at its eafe between the 

 two leaves : neverthelefs, it fall kept feeding on 

 the old leaf, for many hours ; and, when it 

 left it, did not begin upon the top of the ten- 

 der leaf, but went down to the leaf- {talk. But 

 on reflection, this is in confonance with nature : 

 the animal had been nourilhed, while in the 

 nidus, with the juices of the old leaf; and 

 after its enlargement, the fame juices, and 

 thole of a fimilar nature, were moft fuitable 

 to its acquired habit. Inftinct, therefore, 

 led it to feed upon its fofter plant; and to 

 prefer the rigid to the tender part of the 

 young leaf. 



SEPTEMBER 9. The eggs depofited on 

 Saturday the thirty-full of Auguft, are 

 beginning to come forth to-day ; which is only 

 the ninth day from the time of their being de- 

 pofited : the leaves young, healthy, and fuc- 



culent;
