It will be remarked, that when Mr. H. first visited the spring, he was 

 there three weeks without experiencing any material alleviation of his 

 disorder ; the cause of which seems to be, that he was then too weak 

 to go much abroad, so as to unite exercise with the use of the water., 

 and that his stay there was too short. But that sort of change had 

 already commenced, which many subsequent instances showed to be 

 immediate precursors of a solution of the existing morbid state. It 

 appears, from the history of the case, that collections of sabulous 

 matter take place in the patient's kidneys during any considerable inter- 

 ruption of the chalybeate, especially if, at the same time, he applies 

 himself closely to his professional avocations. It is equally established, 

 that the chalybeate acts upon the sabulous matter ; for this is, at length, 

 evacuated along with the urine which it blackens, and the dark colour, 

 as well as the discharge of sand, continues more or less, according as 

 the previous disuse of the water has been longer or shorter. If, 

 after this, the mineral water be persevered in, it prevents the forma- 

 tion of any new concretions, for the discharge of the dark sediment 

 ceases, the urine returns to its natural colour, and there is no new ne- 

 phritic symptom. 



Such is the course invariably experienced by the patient at the 

 spring, where air and exercise, and a vacant mind go hand in hand, with 

 the drinking of the chalybeate : but in the city where, in spight of the 

 physician's remonstrances, profitable business occasionally forces him 

 to longer sittings, greater application, and stronger exertions than are 

 compatible with the delicacy of his health, he still has an attack at dis- 

 tant intervals, though comparatively so slight, that it scarcely deters him 

 from the indulgence of books and study. A speech of two or three 

 hours in court, or any vehement affection o£ mind, will bring on a 

 paroxysm as readily as would a thorough wetting, or a fortnight's con- 

 finement.
