![(a) PLETHORA, It is characterised by excess of blood, by a preponderance of the blood-globules over the fibrin, by a deep red, tenacious blood. It involves the direct manifestations of venosity in the inverse . ratio of the amount of blood which the organism is capable of arterializing. It occurs under two opposite and contrasting relations. First, in conjunction with florid nutrition of the textures, fullness of muscle, and especially ample areolar tissue and fat formation. Secondly, as a very marked phenomenon in union with general emaciation,—wasting of the solids [so- called nervous tabes]. Under the latter circumstances, it is observable both in very delicate children, during the first months of their life, and in insane adults [in hypochondriasis, melancholia, &c.]. In the dead body, the general overloading of the vascular system, and occasionally surpassing hyperemia of various organs, especially of the lungs or of the brain, or of the liver and entire portal system are manifest. According to the degree of intensity of the crasis, all the soft parts are more or less deeply coloured. In the emaciated, the common integuments exhibit vast patches of a purple, or of a bluish leaden hue. Plethora predisposes to congestion, to hemorrhage, to blen- norhoid, albuminous, and serous exsudations of greater or less moment in proportion to their amount and to the importance of the organs concerned. In corpulent, square-built [apoplec- tic] individuals hyperemize of the lungs are frequent. In these the plethora often of itself, but more commonly through acute serous effusion into the bronchia and ling-cells, proves speedily fatal. Moreover, the plethora occasions dilatation of the heart, with subsequent, progressive augmentation of its substance [hypertrophy]. (0) THE TYPHUS CRASIS. It compasses the entire nature of typhous disease, and is at the root of all its phenomena, whether of substantive change or of functional disturbance. The typhus crasis is marked by the destruction—the dimi- nution—of the fibrin, and the comparative preponderance of the blood-globules. The typhous blood is in various degrees](https://iiif.wellcomecollection.org/image/b33099078_0005_0407.jp2/full/800%2C/0/default.jpg)
