ON THE PATHOLOGICAL MORPHOLOGY OF SOME ANIMAL FLUIDS 235 



The white pellucid fluid of a serous cyst (morsus diaboli) con- 

 tains white, perfectly round, smooth globules, destitute of all co- 

 vering, smaller, or a little larger than the globules of the blood. Plate 

 10, fig. 81. 



The white pellucid serous fluid, with which the skin is rendered tur- 

 gid in oedema, contains white or yellowish globules with stellate points.

OF THE ULCERS AND TUMID MESENTERIC GLANDS OF ABDOMINAL 



TYPHUS. 



(Of Ileo-Typhus Ulcerous Ileitus Gastro-enteric Fever, inclining to 

 Nervous Gastro-enteritis Nervous Inflammatory Fever Versatile 

 Nervous Nervous Fever with Stupor.} 



Abdominal typhus, that multiform disease, designated by so many 

 names by the most celebrated authors, has as many forms. In this 

 place we shall speak of the pathological mutations of the substance 

 and texture of the inferior part of the ileum ; also of mesenteric glands 

 adjacent to this, and of the changes in the spleen. 



In bodies examined on the fifth day of the disease, besides a turgid 

 state of the membranes of the ileum, there is seldom any kind of disease 

 to be seen. 



Those who die on the tenth day, besides a turgid state of this 

 membrane of the ileum, show roughish, somewhat elevated lenticular 

 or oblong patches, the extent of which exceeds one or two inches, called 

 crude infiltrations by the most celebrated anatomists. The mucous 

 membrane covering the lenticular infiltrations, slightly adheres to them, 

 and is easily removed from the part, and thrown into folds ; but the 

 mucous membrane lying over the oblong infiltrations, adheres firmly to 

 them. 



The muscular coat is intimately joined to all the crude infiltrations. 



The infiltrations thrust forward the mucous membrane, whose sur- 

 face is equal and smooth, whilst they are lenticular ; but when it covers 

 the oblong patches, it is uneven and furnished with many small eleva- 

 tions and depressions. The places which the oblong patches occupy, 

 correspond to the seat of the glands of Peyer. 



The texture of the infiltrated patches is firm, tenacious, white, or 

 yellowish- white, and a white, limpid, serous fluid is extricated by pres- 

 sure, which, investigated by the microscope, contains white globules,, 

 composed of a smooth covering filled with the smallest molecules. The
