![§ 59. In HARDENING, énduratio,’ the fluid poured into the tissue of the diseased part under inflammation is more or less coagulated, mingled with the normal elementary parts of the organ, and consolidated into a firm mass. The substances effused are fibrous matter, and sometimes also albumen; in proportion as both are coagulated in a greater or less degree, and retain the animal fluid enclosed in them, or have been deprived of it by previous absorption, is the degree of harden- ing very different, till at length the effused and coagulated substance becomes organized, that is, assumes the character of cellular tissue, forms meshes, plates, fibres, &c., acquires small blood-vessels, and has now become a permanent part of the tissue. ‘The more often inflammatory irritation recurs in an already hardened part, the greater becomes the degree of induration, which, in itself, also naturally varies, both accord- ing to the difference of the usual consistence of the organ attacked, as well as to the difference of the character of the inflammation; thus, especially, if inflammation occur in torpid or debilitated parts, it assumes this termination. ‘Thickening and hardening of a part is also not unfrequently produced by long continued pressure. Should they be membranes which have become thickened and hardened, they remain mostly thick, and become opake, although they had been previ- ously transparent; has a part, in its healthy state, a loose and soft texture, it can be rendered by the hardening as firm and tough as the liver, a vice which, when occurring in the lungs, has been named hepatisatio.” If with hardening already set up in the cellular tissue, we find, accompanying inflammation, an increased flow of blood, and increased redness, this con- dition is called the RED HARDENING, éxduratio rubra: but on the contrary, if the inflammation have entirely subsided, and the quantity of blood and redness in the diseased parts are diminished, owing to the compression and adhesion of the vessels, then such is called WHITE HARDENING, induratio alba.‘ The latter not unfrequently becomes so exceedingly hard, that the indurated parts assume a true sinewy appear- ance, nay, even actually run into bone.
