264 ON THE PATHOLOGICAL MORPHOLOGY OF SOME ANIMAL FLUIDS. 



limpid fluid, compose the pathological fluid called pus, however then, at 

 least, it can be distinguished by re- agents, while this pathological pro- 

 duct, freed from all proper mucus, may be submitted to examination, 

 which then, at least, can be done, provided that access to the patholo- 

 gical substratum is easily attained, as in the mucous membrane of the 

 tongue, of the lips, palate, cheeks, nostrils, vagina, neck of the womb, 

 nymphae, anterior part of the urethra, inferior part of the rectum, con- 

 junctivse of the palpebrse and of the globe ; but the product of inflamma- 

 tion formed from a breach of continuity of the mucous membrane in 

 remoter parts, is almost always intimately mixed with the product of an 

 inflamed and irritated adjacent mucous membrane, and in no manner is 

 it discharged separate ; thence the result of the examination of these 

 mixed products is doubtful. Here we number the product of inflamma- 

 tion from breach of continuity of the mucous membrane of the pharynx, 

 oesophagus, and whole alimentary canal, even to the inferior portion of 

 the rectum, moreover that of all the air passages, ureters, urinary blad- 

 der, urethra, even to the scaphoid fossa, fallopian tubes, and cavity of the 

 uterus, Eustachian tubes, and its propagations, sinuses, and different 

 ducts, except a great part of the mucous membrane may have been des- 

 troyed ; for then, from the great quantity of pus prevailing, there is not 

 found sufficient mucus. Hence, pus nearly pure is thrown out, as is wont 

 to occur in phthisical patients affected with large vomicse of the lungs. 



Not only the substratum, but also (B), the different intensity of the 

 process of inflammation produces various media, with which globules 

 of inflammation appear mixed ; thus an irritated serous membrane gene- 

 rates a few globules united with a large quantity of aqueous fluid, and 

 forms turbid serous fluid. 



But a more intense inflammation of a serous membrane equally occa- 

 sions a few globules, which united to plastic lymph, form intestinal 

 adhesions. The same occurs in a mucous membrane ; a slight irrita- 

 tion or inflammation produces globules united to mucus, but a more 

 intense inflammation generates globules united to plastic lymph, and 

 causes the exudation of croup, a degree of inflammation, which, when 

 it occurs in the parenchyma of organs, produces indurations, hepatiza- 

 tions, and inflammatory tumours. 



In suppurating wounds the same pathological product is distinguished 

 by the name of granulations, and in simple recent wounds, by that of 

 varnish or plastic lymph, by which the lips of wounds are quickly united, 

 when they heal by what surgeons term " the first intention." 



2nd. Pus of normal inflammation differs according to the different du- 

 ration of the pathological process ; for the globules, the inflammation 

 commencing, in a relation to the medium with which they are mixed,
