    acidity reached its highest point, but did not on any occasion cause the formation of uric acid crystals. The mode of examination was the following. Two test solutions were made, the one with carbonate of soda, the other with dilute sulphuric acid. Each measure of either test was made equivalent to -j^th of a grain of dry and pure carbonate of soda. A bottle containing 1000 grains at least of urine was filled and weighed. The urine was heated in a cup to 120°, and then the test solution was dropped in from a gra- duated tube; so that the urine, when acid, was made, by alkali, just neutral to the most delicate test-paper; and when alkaline, it was made just neutral by acid. The number of measures required gave the degree of acidity or alkalescence of the urine. In the second part of this paper, it. will be seen from experiments made four months previously to these, that the same kind of variations took place then ; and in the same case two years before, and again even three years previous to these experiments, the same fact was noted. Thus, October 13, 1846, breakfast on bread and meat at 9 a.m. Urine passed at 1 p.m., clear. Specific gravity . . 1022-8. Alkaline. Urine passed at 3 p.m., clear. Specific gravity . . 1019-9. Acid. And October 28, 1845, breakfast at 9h 15m. h m Urine passed at 10 a.m. Acid. Urine passed at 12 30 p.m. Alkaline. Urine passed at 3 Acid. (1.) October 14, 1848. Breakfast on bread, meat and coffee, at 8h 45m a.m. Dinner at 5h 50m p.m. Fish, meat, potatoes and water. h m Spec. gr. Acidity per 1000 grs. of urine. Appearances. Water passed at 7 15 A.M. thrown away. Water passed at 8 45 = 102 IT + 11-75 measures. Clear. Water passed at 9 55 = 1023-5 + 8-79 Clear. Water passed at 11 15 = 1022-7 — 11-73 Clear. Water passed at 12 = 1024-4 — 29-28 Thick from phosphates. Water passed at 12 50 p.m. = 1024-0 -10-74 Clear. Water passed at 2 15 = 1021-5 + 6-85 Clear. Water passed at 3 50 = 1024-1 + 15-62 Clear. Water passed at 5 50 = 1024-4 +21-47 Clear. Water passed at 7 55 = 1029-6 + 15-54 Thick from urates. Water passed at 10 45 = 1029-8 - 5-82 Clear. Water passed at 6 30 a.m. = 1023-3 + 9-77 Clear. Water passed at 7 40 = 1025-3 + 13-65 Clear. (2.) Breakfast at at 5h 45“ p.m. 8h 45m. a.m., the same as the day previous. Dinner the same, Water passed at 8 45 = 1025-6 + 15-60 measures. Clear.
