A bruise or contusion may be known by the eye; for first it will be red or black, then livid, yellow, green, and at last black again; unless it be flight, for then it recovers its natural colour without any application. When you have reason to suspect a bruise, and it is not discoverable by the eye, you may feel about the place, and if you feel an un-usual softness, or a fluctuation of extravasated blood, you may be sure that is the part affected: as also, when there is a pain and stiffness. If the inward parts are bruised, you may know which it is by one or other of the functions being hurt.

When the bruise is flight, as that of a child's fore-head by a fall, it may be relieved with spirit of wine, or camphorated spirit of wine, or hungary water; or by dipping a bit of thick brown paper in very cold water, and laying it on the swelling. If the bruise is large, you may apply lime-water mixt with camphorated spirit of wine; or a spunge dipt in fresh urine, in which Venice soap has been dissolved, or opodeldoc made warm. If the bruised part tends to a gangrene, a surgeon must be sent for immediately to scarify the part, and set the stagnating fluids at liberty: after which it must be fomented with the common fomentation of the London dispensatory, rubbing the tumor with hot cloths before it is fomented. Or you may take three ounces of powder of briony root, and as much Venice treacle, and bring it to the consistence of poultice with sea-water, salt water, or common water.

When the bruise is considerable, internal remedies should never be neglected; such as the decoction of betony, males speedwel, rosemary, or sage, drank plentifully. When the bruise is internal, you may give a pint a day of the following decoction; "Take the leaves of ground ivy and plantane, half an ounce of each; of spring water three pints; boil it to a quart, and sweeten it with an ounce of fine sugar." Or give thirty or forty drops of the traumatic balsam, or Friar's balsam, several times a day. Or you may advise a dram of sperma ceti, in a draught of the above decoction. The patient must eat no flesh, nor drink strong liquors, but live wholly upon broths and spoon-meat.

When the fluids in the bruise are dispersed or evacuated, the fore may be cured as an ulcer; which fee.
