_Treatment._ When due to poison taken by the stomach this must be stopped, and the stomach and bowels evacuated by an emetic (ipecacuan) and laxative (sodium sulphate). Appropriate treatment must be made in case of burns or skin eruptions. When surgical cases are due to infection rather than simple shock or sympathetic irritation, antiseptic injections of the bladder are indicated. In all cases alike a warm bath is an important adjunct. When irritation is due to cantharides, it may be calmed by camphor, 2 grains every three or four hours. Other anodynes may be given as required. Rest is essential and, as appetite is recovered, a moderate amount of amylaceous puddings. A warm building or comfortable clothing is desirable. NEPHRITIS. 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. 4th. _Chronic diffuse_ (_desquamation, interstitial_) _nephritis._ 5th. _Suppurative nephritis and pyelo-nephritis_, infection may be from injury. 6th. _Perinephritis_: infection of connective tissue with adjacent disease. _In domestic animals_ the following distinctions have been made: 1st. _Acute nephritis._ 2d. _Chronic nephritis._ 3d. _Purulent nephritis and pyelo-nephritis._ 4th. _Perinephritis._ ACUTE NEPHRITIS. ACUTE BRIGHT’S DISEASE.
