    fluid, and of a deep purple colour. It forms, if any, but scanty, loose, soft, and humid, deliquescent coagula, reddened by the imbibition of pigment-holding plasma. | The corpses of typhous individuals are remarkable for the deep, dingy, bluish gray coloration of the common integument, for the deep purple of the death-spots, for the dark rnsset hue and the rigidity of the muscles, and for the dryness of the areolar tissue. The serous membranes, and especially the peritoneum are of a dull gray, lack-lustre, and occasionally suffused with a tenacious humour. All the textures in contact with blood appear discoloured from imbibed heematin, of a peculiar shade, verging from viclet colour upon brown, In the next place, the multifarious local hypereemiz have to be noticed. They are due to the paralysing influence of the blood upon determinate ranges of the nervous system, either at the periphery or at the centres. Foremost amongst them are local hyperzmiz of the mucous membranes, of the lungs, of the brain, and its membranes, of the spinal cord, of the common integuments. ‘They often display the attributes of so- called hypostasis. Upon mucous membranes they frequently degenerate into hemorrhages, which occur also, although far more rarely, in parenchymata, for example, in the brain. The typhus-crasis manifests a very marked relation to mu- cous membranes, especially to the lymphatic glands and to the spleen. In middle Europe it is the mucons membrane of the intestine and especially of the ileum, rarely the bronchial mu- cous membrane with the lungs and the bronchial glands; in the North, it is rather the last mentioned, namely, the respira- tory tract; in the south, [in pest-typhus] it is the peripheral lymphatic gland system, in which the crasis becomes localized. In the form of a typhous inflammation it determines, in the follicular apparatus of the ileum and in the mesenteric glands a peculiar marrow-like product which, in intense ‘cases, closely resembles medullary carcinoma. The very variable consistency of the typhus-substance points to variations in the typhus-crasis itself; to different degrees of plasticity in the typhous blood plasma. ' Pus-formation, we have to observe, is alien to the genuine ty- phous process whether general or local. Wherever it does occur, itis founded ina degeneration or change in the typhus-crasis, of
