Whitlow, or Whitloe, a painful swelling of the extremities of the fingers, beneath the nails, and usually terminating in a discharge of serous fluid, that is frequently so acrid as to corrode the periosteum, or membrane lining the bones, which thus become carious. It is always attended with inflammation, and sometimes to so violent a degree as to affect the whole arm.

Where whitloes arise from external causes, it will be proper to apply emollient poultices, in order to effect a suppuration. Should such tumors, however, proceed from unknown causes, it will be advisable to apply a few leeches, and afterwards ardent spirits, or other astringents; but, if the bones have already become carious, a total or partial removal of the affected part can alone effect a cure. The following preparation has been extolled, as being very efficacious in common cases of whitloes; though we cannot vouch for its success : - Take equal parts of pel-litory of the wall, previously bruised, and hog's-lard; let them be properly mixed, folded in several papers, and surrounded with wood-embers, of such a degree of heat as to incorporate the ingredients, without burning the covering. The ointment, thus prepared, must be spread on a piece of soft linen, and applied to the whitloe, two or three times every day, till the tumor be healed.
