[30.]
Specific gravity of the urine rose from 1005 (before taking) to 1010, 1015, 1020, and at last 1025; the urine was previously reddish-yellow, now constantly became lighter-colored; and soon after stopping the drug it resumed its dark color as before, 4.

GENERAL SYMPTOMS. [40.]

Before taking the drug, the blood was dark-red, thickish, containing only a few colorless corpuscles, many elementary corpuscles; coagulated in eight minutes; the separation was very rapid, so that after an hour the clot did not seem much larger than after fifteen hours; clot very firm; after taking saltpetre, the blood was of the color and consistence of cherry-juice; numerous colorless corpuscles; coagulated in three minutes and thirty-three seconds; the separation of serum was somewhat slow, the clot not firm, 3.
Before the proving, the blood was dark-red and thick, with rather numerous colorless corpuscles; coagulated in nine minutes; the clot firm and elastic; after taking the drug, the blood looked like cherry-juice, contained numerous and very large colorless corpuscles; coagulated in four minutes and fifty-nine seconds, 4.
Before taking, the blood was dark-red, contained numerous colorless corpuscles, coagulated in seven minutes and four seconds; clot firm and elastic; after taking, the blood looked like cherry-juice, contained fewer and very much larger colorless corpuscles; coagulated in six minutes and twenty-three seconds; the clot very soft and friable, 5.
Before taking the drug, blood dark-colored, containing rather numerous colorless corpuscles, mostly larger than the colored ones; coagulating in thirteen minutes and five seconds; clot firm; after taking the drug, blood lighter-colored, containing very numerous large colored corpuscles; coagulating in seven minutes and fifteen seconds; clot soft and very friable, 6.
Before the proving, the blood was bright-red coagulated in twelve minutes and thirty-six seconds; clot firm, elastic; afterwards, the blood looked like cherry-juice; the red corpuscles paler than normal; numerous colorless corpuscles; coagulated in six minutes and fifty seconds; clot soft, very friable, 7.
The color and consistence of the blood was changed, so that it became similar to cherry-juice; the number and size of the colorless corpuscles increased; the color of the red corpuscles became paler; the blood coagulated more rapidly; there was an increase of the water of the blood, and a corresponding diminution of the solids; decrease of the fatty elements; increase of the inorganic salts of the serum (incinerated residue); diminished firmness and cohesion of the coagulum, diminution of its solid constituents, and increase of the inorganic salts, 8.
The result of one examination each time, before and after taking the drug, showed an increase of the water in the defibrinated blood, and also of the serum; a diminution of the solid constituents of the defibrinated blood, as of the sternum; a general diminution of the blood-corpuscles; diminution of albumen, and slight increase of the fibrin; increase of the soluble salts; less coagulum, and more serum, .
