BUTTERFLY. 
These tare insects inhabit the island of Amboyna, 
from whence they are brought to England and pre- 
served in the cabinets of the curious. 
As the history of any particular individual of 
this numerous genus does not contain any thing 
Sufficiently interesting to make it of importance to 
the general reader, we have thought it unnecessary 
to give more than one example, and shall conclude 
with a concise description of the different parts of 
these insects. 
The eyes of butterflies differ in size, and some- 
what in formation. In one species they are large, 
in another small ; in some they describe a larger 
portion of a sphere than in others ; but in all the 
outward coat has a lustre which reflects from its 
surface the various prismatic colours. The cause of 
these different tints is discovered when the eye is 
examined under a proper magnifying glass ; for it 
will then be found to consist of a great number of 
sides, or small lenses, each of which reflects a 
portion of light, and the whole may be compared 
to a brilliant cut diamond. This disposition of the 
parts of the eye enables the insect to see perfectly 
well in every direction, though the whole together 
is fixed immoveably in the head. 
The trunk with which butterflies are furnished, 
is the organ through which they conduct all their 
nourishment to the mouth. It is a flexible tube 
placed exactly between the eyes, and when the 
animal is not in search of food is generally rolled 
up. With this the butterfly explores the bottom
