INFLAMMATIONS. 53 



the bronchise, which the learned Mr. de Haen says he had so 

 often observed, when there was no ulceration of the lungs ; and 

 this explanation is at least more probable than Mr. de Haen's 

 supposition of a pus formed in the circulating blood. 



CCCL. To conclude this subject, it would appear that the 

 effusion into the bronchiae, which we have mentioned, often 

 concurs with the effusion of red blood in occasioning the suffo- 

 cation which fatally terminates pneumonic inflammation ; that 

 the effusion of serum alone may have this effect ; and that the 

 serum poured out in a certain quantity, rather than any debility 

 in the powers of expectoration, is the cause of that ceasing of 

 expectoration which very constantly precedes the fatal event. 

 For, in many cases, the expectoration has ceased, when no other 

 symptoms of debility have appeared, and when, upon dissection, 

 the bronchiae have been found full of liquid matter. Nay, it is 

 even probable, that, in some cases, such an effusion may take 

 place, without any symptoms of violent inflammation ; and, in 

 other cases, the effusion taking place may seem to remove the 

 symptoms of inflammation which had appeared before, and thus 

 account for those unexpected fatal terminations which have 

 sometimes happened. Possibly this effusion may account also 

 for many of the phenomena of the Peripneumonia Notha. 



CCCLI. Pneumonic inflammation seldom terminates by re- 

 solution, without being attended with some evident evacuation. 

 An haemorrhagy from the nose happening upon some of the 

 first days of the disease, has sometimes put an end to it ; and 

 it is said, that an evacuation from the haemorrhoidal veins, a 

 bilious evacuation by stool, and an evacuation of urine with a 

 copious sediment, have severally had the same effect : but such 

 occurrences have been rare and unusual. 



The evacuation most frequently attending, and seeming to 

 have the greatest effect in promoting resolution, is an expector- 

 ation of a thick white or yellowish matter, a little streaked with 

 blood, copious, and brought up without either much or violent 

 coughing. 



Very frequently the resolution of this disease is attended with, 

 and perhaps produced by, a sweat, which is warm, fluid, copi- 

 ous over the whole body, and attended with an abatement of
