weiglis but a scruple, will, when gorged, weigh more than 
two drachms. 
When leeches are to be applied, the best way is to take 
them from the water in which they are contained, about 
an hour before, for they thus become more voracious, and 
fasten more readily. When saturated with blood, they 
generally fall off of themselves ; but if it be thought neces- 
sary to take them from the wound, care should be used to 
pul! them very gently, or even to sprinkle them with salt, 
if they continue to adhere; for if they be plucked rudely 
away, it most frequently happens that they leave their teeth 
'n the wound, which makes a very troublesome inflamma- 
tion, and is often attended with danger. Iftheybesiow 
in fixing to the part, they are often enticed by rubbing it 
with milk or blood, or water mixed with sugar. As saft is 
poison to most insects, many people throw it upon the leech 
when it has dropped from the wound, which causes it to 
disgorge the blood it has swallowed, and it is then kept for 
repeated application. They seldom, however, stick after 
this operation ; and, as the price is but small, fresh leeches 
should always be applied whenever such an application is 
thought necessary.

Great West Indian Locust — The House Cricket — The

We come now to a second order of insects, that are pro- 
duced from the egg, like the former, but not in a perfect 
state ; for when first excluded they are without wings. 
To this order we may, in the first place, refer the Libel- 
La, or Dragon fly. 
Of all the flies which adorn or diversify the face of na- 
ture, these are the most various and the most beautiful ; 
they are of all colours; green, blue, crimson, scarlet, 
"white, Sic. 
They are distinguished from all other flies by the length 
°f their bodies, the largeness of their eves and the beautiful 
transparency of their wings, which are four in number.
