Manual of pathological anatomy . tubes and thestroma generally are oftenuniformly thickened.

A very important and signifi-cant alteration has been observed in the condition of the smallarteries by Dr. Johnson; he finds their coats considerably thickened(Fig. 162), both the inner of longitudinal and the outer of circularfibres, and he regards this thickening as an instance of true hyper-trophy induced by the increased pressure exerted upon theirparietes by the retardation of the circulation through the inter- * Traube disting-uishes two forms of gi^anular kidney; that in -which the small-celled infiltration is especially abundant round the Malpighian capsules, and that inTvhich it occurs round the intertubular Cortical part of a very granular kidney,containing very numerous microscopic tubes are very much degenerated andbroken up.

There is also often general thickening ofall the coats, rigidity, atheroma, and calcareous degeneration of thearterial wall, with diminution of its calibre, as has been wellfigured by Dr. Lionel Beale. No particular change is observablein the before-mentioned capillaries, or in the veins, except that thelatter often contain firm coagula of blood, which are more or lessclosely adherent to their walls, so as sometimes to constitute actualthrombosis.
