ingly in our remedial measures. It has been 

 stated, that, in all cases of nausea, the circulation 

 is depressed, because the lungs contain a greater 

 quantity of blood, or blood not oxijgenated to its 

 usual extent. The existence of both states is 

 most probable. If inflammation be present, can 

 we diminish the excited action of the morbid 

 part by persevering in a long course of nauseat- 

 ing medicines ? This practice has been found use- 

 ful in pneumonia ; but is the analogy between the 

 two affections sufficiently close to allow of the 

 same treatment ? If inflammation be the cause of 

 the disordered symptoms in both instances, there 

 is a manifest difference in the extent and seve- 

 rity of the disease, and also in the general conse- 

 quences. 



DXLVIII. I am disposed to regard the follicles 

 of the mucous membrane, or at least those or- 

 gans appropriated to the secretion of mucus, 

 and which must be supposed to exist throughout 

 the minute bronchial tubes,* as the primary seat 

 of acute or chronic inflammation, producing or 

 concomitant with phthisis. These, by a deter- 

 mination of blood to the lungs, whether from 



* " In most mucous membranes are found minute oval or 

 spheroidal bodies, sligbtly elevated, and presenting an orifice 

 leading to a blind or shut cavity. As they are believed to se- 

 crete a fluid analogous to or identical with raucus, they are 

 named mucous glands. In the state of health these bodies are 

 so minute that it is very difficult to recognize them. 1 have 

 seen them, nevertheless, in the tracheo-bronchial membrane, 

 by the eye and by a lens." Elements of General and Patho-
