CATERPILLAR. 
There are many different sorts of Cater- 
pillars: some of them are rough., hard, and 
stiff; others are soft, smooth, and tender; 
some horned, either in the head or tail ; others 
without horns; all having many feet. The 
Caterpillar has its original from the seed of 
a butterfly, which it leaves on the leaf of a 
nettle. The butterfly is tile insect in perfec- 
tion. The Caterpillar, grub, or worm, are 
certain mimics or disguises of it for a time, 
in which one and the same animal is cir- 
cumvested by nature, for various uses, viz., 
with the disguise of a Caterpillar, that it 
may eat this or that food ; but of a grub or 
worm, that its joints may be finished or 
hardened.
