OF BLOODY URINE.

riding, or any violent motion. It may also proceedfrom ulcers of the bladder, from a stone lodged in thekidneys, or from violent purges, or sharp diureticmedicines, especially cantharides.

Bloody urine is always attended with some degreeof danger: but is peculiarly so when mixed with pu-rulent matter, as this shews an ulcer somewhere in theurinary passages. Sometimes this discharge proceedsfrom excess of blood, in which case it is rather to beconsidered as a salutary evacuation than a disease.If the discharge, however, be very great, it maywaste the patient's strength, and occasion an ill habitof body, a dropsy, or a consumption.

The treatment of this disorder must be varied ac-cording to the different causes from which it proceeds.

When it is owing to a stone in the bladder, thecure depends upon an operation, a description ofwhich would be foreign to our purpose.

If it be attended with a plethora, and symptoms ofinflammation, bleeding will be necessary. The bodymust likewise be kept open by emollient clysters, orcooling purgative medicines, as cream of tartar, rhu-barb, manna, or small doses of lenitive electuary.

Where there is reason to suspect an ulcer in thekidneys or bladder, the patient's diet must be cool,and the drink of a soft, healing, balsamic quality, asdecoctions of marsh-mallow-roots with liquorice, solu-tions of gum arabic, &c.
