Insects. 



The manner in which the various animals 

 reathe differs very greatly. In Quadrupeds, 

 irds, and Reptiles, breathing is performed 

 irough the mouth, by means of the lung; 

 1 Fish, the gills answer the purpose of ex- 

 ■acting air from the water : in Insects, a 

 umber of little spiracles, or little breathing 

 olee, are placed on different parts of the 

 ody; the engraving shows two of these 

 reath-openings in the pupa or butterfly.

 slender tube attached to one of the rings of 

 its body, ne;u the tail : the end of this tube 

 is surrounded with a fringe of hairs, which

 d with a belt of fine hairs, by means of 

 vhich it may be completely closed, as in 

 he left hand figure, to prevent the entrance 

 )f water, or any other fluid that would be in- 

 urious to it. Oil, however, will penetrate 

 ind destroy the insect. The air-opening in 

 ;he larva of the gnat, has a very extraordi- 

 lary appearance : the creature, in this state, 

 jeing an inhabitant of the water, needs 

 lome contrivance to give it the means of ob- 



lew state of things, and will herself, if man does 

 not, eradicate the bullrushes and other products 

 jf watery lands, and substitute them by grasses 

 which flourish on dry soils.— Ed.

 when expanded, has sufficient bouyancy to 

 keep the body floating; and when the insect 

 sinks in the water, these hairs are folded 

 over the opening of the tube, and enclose a 

 small bubble of air, which serves as a supply, 

 until its return to the surface. 



Several parts of the Spider are very curious 

 and none more so than the spinning appa- 

 ratus : annexed is a highly magnified view of 

 this rope making organ. The thread of the 

 spider, it will be seen, small as it appears to 

 be to the naked eye, is composed of numer- 

 ous filaments, of a still finer nature, which 

 unite together at a short distance from the 

 openings through which they are drawn.

The Palpi, or feelers of the spider have a 

 curious pointed hook at the end of each, 

 which closes, for the purpose of taking hold 

 of any thing, something like a clasp-knife.
