| LECTURE XV.—Passive Processes. Fatty Degeneration. | 356 |
| Passive processes in their two chief tendencies to degeneration; Necrobiosis (softening and disintegration) and induration.—Fatty degeneration. Histological history of fat in the animal body; fat as a component of the tissues, as a transitory infiltration, and as a necrobiotic matter.—Adipose tissue. Polysarcia. Fatty tumours. Interstitial formation of fat. Fatty |
