Andouard mentions an instance of blue bile in a woman, blue flakes
being found in her vomit. There was no trace of copper to be found in
this case. Andouard says that the older physicians frequently spoke of
this occurrence.

Rhodius speaks of the sweat being sweet after eating honey; the
Ephemerides and Paullini also mention it. Chromidrosis, or colored
sweat, is an interesting anomaly exemplified in numerous reports. Black
sweat has been mentioned by Bartholinus, who remarked that the
secretion resembled ink; in other cases Galeazzi and Zacutus Lusitanus
said the perspiration resembled sooty water. Phosphorescent sweat has
been recorded. Paullini and the Ephemerides mention perspiration which
was of a leek-green color, and Borellus has observed deep green
perspiration. Marcard mentions green perspiration of the feet, possibly
due to stains from colored foot-gear. The Ephemerides and Paullini
speak of violet perspiration, and Bartholinus has described
perspiration which in taste resembled wine.

Sir Benjamin Brodie has communicated the history of a case of a young
girl of fifteen on whose face was a black secretion. On attempting to
remove it by washing, much pain was caused. The quantity removed by
soap and water at one time was sufficient to make four basins of water
as black as if with India ink. It seemed to be physiologically
analogous to melanosis. The cessation of the secretion on the forehead
was followed by the ejection of a similar substance from the bowel,
stomach, and kidney. The secretion was more abundant during the night,
and at one time in its course an erysipelas-eruption made its
appearance. A complete cure ultimately followed.

Purdon describes an Irish married woman of forty, the subject of
rheumatic fever, who occasionally had a blue serous discharge or
perspiration that literally flowed from her legs and body, and
accompanied by a miliary eruption. It was on the posterior portions,
and twelve hours previous was usually preceded by a moldy smell and a
prickly sensation. On the abdomen and the back of the neck there was a
yellowish secretion. In place of catamenia there was a discharge
reddish-green in color. The patient denied having taken any coloring
matter or chemicals to influence the color of her perspiration, and no
remedy relieved her cardiac or rheumatic symptoms.
