In this affection the colored sweating appears symmetrically in various parts of the body, the parts commonly affected being the cheeks, forehead, side of the nose, whole face, chest, abdomen, backs of the hands, finger-tips, and the flexors, flexures at the axillae, groins, and popliteal spaces.

Although the color is generally black, nearly every color has been recorded.

Colcott Fox reported a genuine case, and Crocker speaks of a case at Shadwell in a woman of forty-seven of naturally dark complexion.

The bowels were habitually sluggish, going three or four days at least without action, and latterly the woman had suffered from articular pains.

The discolored sweat came out gradually, beginning at the sides of the face, then spreading to the cheeks and forehead.
