174 THE HOUSE I LIVE IN. 



" Naturalists say there is one species of mag- 

 got-fly that mistakes the odor of some kinds of 

 snuff, for that of putrid substances, and depos- 

 its its eggs in it. In warm weather, therefore, 

 it must be dangerous to take snuff which has 

 been exposed to these insects ; for the eggs 

 sometimes hatch in two hours, and the most 

 tremendous consequences might follow." * 



THE MOUTH, INTERNALLY. The mouth, of 

 itself, is one of the apartments of the human 

 body, and a very curious apartment too. When 

 I spoke of it as one of the doors, I referred prin- 

 cipally to the aperture formed by a cleft of the 

 lips, or the external mouth ; and not to the 

 internal, or more important part. 



In this chamber the entrance chamber of 

 the front door we find the teeth, the tongue, 

 the palate, and several little glands. This en- 

 trance chamber is larger than the hall or space 

 beyond it. Doors also open from it into sev- 

 eral other apartments.
