NEPHRITIS — IXFLAM^IATIOX OF THE KIDNEYS. 727 



around the body have been found to be attended with benefit, 

 in combination with the medicines mentioned. No veiy 

 active diuretic should be given, but the bowels kept in a 

 soluble state through the use of enemata and sulphate of soda, 

 or magnesia given in quantity in the drinking-water. After a 

 few days, when the more pronounced pyrexial symptoms have 

 abated, moderate doses of the solution of the perchloride of 

 iron, or iron in combination with quinine, will be found of 

 much advantage, some of the simple salines being still con- 

 tinued in the drinking-water. 



2. Inflammatory Action unattended witli Dropsy or Albuminous 

 Urine ; Interstitial and Parenchymatous Nephritis with Renal 

 Abscess.— Besides those inflammatory and non-inflammatory 

 changes more properly located in the tubular structures, we 

 occasionally meet with an active form of inflammation in which 

 the diseased processes and tissue-changes, although to a great 

 extent aftecting all the elemental parts, yet seem to expend 

 their chief activities on structures other than these. In the 

 former morbid actions it has been noticed that dropsy and 

 albuminuria are marked features, with extensive implication of 

 other organs and structures essential to life ; in the latter, 

 albuminuria and dropsical swellings, instead of the rule, are the 

 exception. Such cases seem to arise less from impure blood, 

 the result of systemic disturbance and consequent tissue-change 

 and removal, than from injury or irritation of a more truly 

 local character, induced by external agents or influences, as 

 violence, over-exertion, and probably also the action of irritating 

 materials, which find an entrance into the animal body either 

 by the alimentary canal or otherwise. 



This form of nephritic disturbance is probably more pro- 

 nounced and attractive in the development of symptoms than 

 either of the preceding already noticed, and is that which, 

 above others, has been styled nephritis, as exhibiting in a 

 more characteristic form the usually recognised inflammatory 

 features of parenchymatous organs. The extent of structure 

 involved is variable, and upon this largely depends the ultimate 

 physical appearance of the organ. 



Should the morbid action be trifling in severity, or restricted 

 as to territory invaded, the efliision consequent on the morbid 

 process may be expected to be readily removed, while, where
