kidney by the retrograde action of the ureter. The kidney is 

 nevertheless inflamed more frequently, though in a less degree, 

 from other causes; especially from the intemperate ingurgitation 

 of ale, or other fermented or spirituous liquors. This less de- 

 gree of inflammation is the cause of gravel, as that before men- 

 tioned is the effect of it. The mucus secreted to lubricate the 

 internal surface of the uriniferous tubes of the kidney becomes 

 secreted in greater quantity, when these vessels are inflamed; and, 

 as the correspondent absorbent vessels act more energetically at 

 the same time, the absorption of its more fluid parts is more 

 powerfully affected; on both these accounts the mucus becomes 

 both changed in quality and more indurated. And in this man- 

 ner stones are produced on almost every mucous membrane of 

 the body; as in the lungs, bowels, and even in the pericardium, 

 as some writers have affirmed. See Class I. 1.3. 9. 



M. M. Venesection. Ten grains of calomel given in small 

 pills, then infusion of senna with oil. Warm bath. Then opium 

 a grain and a half. See Class I. 1.3. 9. for a further ac- 

 count of the method of cure. 



15. Cystitis. Inflammation of the bladder is attended with 

 tumour and pain of the lower part of the belly; with difficult 

 and painful micturition; and tenesmus. It generally is pro- 

 duced by the existence of a large stone in the bladder, when in a 

 great degree; or is produced by common causes, when in a 

 slighter degree. 



The stone in the bladder is generally formed in the kidney, 

 and passing down the ureter into the bladder becomes there gra- 

 dually increased in size; and this most frequently by the apposi- 

 tion of concentric spheres, as may be seen by sawing some of 

 the harder calculi through the middle, and polishing one surface. 

 These new concretions superinduced on the nucleus, which de- 

 scended from the kidney, as described in Class I. 1. 3. 9. and in 

 the preceding article of this genus, is not owing to the micro- 

 cosmic salt, which is often seen to adhere to the sides of cham- 

 ber-pots, as this is soluble in warm water, but to the mucus of 

 the bladder, as it rolls along the internal surface of it. Now 

 when the bladder is slightly inflamed, this mucus of its internal 

 surface is secreted in greater quantity, and is more indurated 

 by the absorption of its more liquid part at the instant of secre- 

 tion, as explained in Class I. 1. 3. 9. and II. 1. 2. 14. and 

 thus the stimulus and pain of a stone in the bladder contribute 

 to its enlargement by inflaming the interior coat of it. 



M. M. Venesection. Warm bath. Diluents. Anodyne 

 clysters. See Class 1.1.3. 9.
