OF LOBULAR INFLAMMATION OF THE PLACENTA. 



THE yellowish- white, hard, friable and fragile substances which occur 

 in the human placenta, occupy a place towards the margin, or on the 

 foetal surface around the larger vessels. They have a thickness of half 

 a line and more, but an extent of 2 4 lines. 



Microscopical investigation teaches us, that these substances are 

 composed of the larger molecules, also of globules, scarcely exceeding 

 in size the blood-discs, having a smooth envelope, and made up very 

 small molecules. Plate 10, fig. 80.* 



GENERAL SUMMARY. 



It is manifest from what has been said, that in every inflammation, 

 whether acute or chronic, suppurative or adhesive, and whether occur- 

 ring on the surface of membranous or in the substance of parenchyma- 

 tous organs, either injured or uninjured, globules are formed which, in 

 inflammation of mucous membranes, being united to the fluid peculiar 

 to those membranes, namely mucus, constitute purulent and puriform 

 mucus, and crude or concocted catarrhal sputa ; in inflammation of se- 

 rous membranes, joined to their peculiar product, viz., serum, they con- 

 stitute at one time turbid serum, and at another a puriform fluid, or 

 purulent exudation ; in cutaneous inflammations they constitute the 

 contents of vesicles or pustules ; in suppurative inflammation, united to 

 a pellucid fluid they constitute pus ; in adhesive inflammation, and in 

 that of croup, joined to the plastic lymph, they form the false membrane 

 of croup or a varnish-like exudation ; in parenchymatous inflammation, 

 united with plastic lymph, they constitute the inflammatory tumefac- 

 tion ; joined with a serous fluid, and filling up minute interstices, they 

 appear as purulent infiltration ; and when collected in larger recently 

 formed cavities, they form the contents of abscesses. 



Hence the products of inflammation
