The renal inflammations have not been fully investigated in the domestic
animals, and even in man, the pathology of several of the forms is still
enveloped in some measure of doubt. _In man_ the following conditions
have been noted:
1st. _Acute parenchymatous nephritis_ with enlarged kidney and
degenerated tubules.
2d. _Chronic parenchymatous nephritis_ with enlarged kidney and
degenerated tubules.
3d. _Acute diffuse_ (_desquamative, interstitial_) _nephritis_ with
enlarged kidney and glomeruli, tubules and connective tissue
degenerated.
