come the means of destroying life. Even if it 

 is extracted, it is very apt to grow again. 



Painful diseases also occasionally arise in the 

 cavity of the cheek. These are sometimes 

 mistaken for tooth-ache. The extraction of the 

 tooth which appears to cause the pain, unless 

 its roots extend through, quite into the cavity, 

 affords, in such cases, no permanent relief. 



Some kinds of head-ache probably have their 

 seat in the hollows of the frontal or forehead 

 bone, near the root of the nose. A very com- 

 mon disease in sheep, is known to be produced 

 by worms in these hollows. The dull, heavy 

 pain so often felt over the eyes, especially when 

 we have what is commonly called a cold in the 

 head, may be owing to a slight inflammation of 

 the membranes of this cavity. 



People ought to be careful about smelling 

 things which give them much pain. Probably 

 the use of most of our smelling bottles is injuri- 

 ous, in the end, to the delicate lining of all these 

 " rooms " connected with the nose. Snuff cer- 

 tainly is, and so is the smoking of tobacco, 

 cigars and opium so common in some coun- 

 tries.
