Rayer speaks of a woman under his care at the Hopital de la Charite affected with chronic peritonitis, who some time before her death exhaled a very decided odor of musk. The smell had been noticed several days, but was thought to be due to a bag of musk put purposely into the bed to overpower other bad smells. The woman, however, gave full assurance that she had no kind of perfume about her and that her clothes had been frequently changed. The odor of musk in this case was very perceptible on the arms and other portions of the body, but did not become more powerful by friction. After continuing for about eight days it grew fainter and nearly vanished before the patient's death. Speranza relates a similar case.
Complexion.—Pare states that persons of red hair and freckled complexion have a noxious exhalation; the odor of prussic acid is said to come from dark individuals, while blondes exhale a secretion resembling musk. Fat persons frequently have an oleaginous smell.
The disorders of the nervous system are said to be associated with peculiar odors. Fevre says the odor of the sweat of lunatics resembles that of yellow deer or mice, and Knight remarks that the absence of this symptom would enable him to tell whether insanity was feigned or not. Burrows declares that in the absence of further evidence he would not hesitate to pronounce a person insane if he could perceive certain associate odors. Sir William Gull and others are credited with asserting that they could detect syphilis by smell. Weir Mitchell has observed that in lesions of nerves the corresponding cutaneous area exhaled the odor of stagnant water. Hammond refers to three cases under his notice in which specific odors were the results of affections of the nervous system. One of these cases was a young woman of hysterical tendencies who exhaled the odor of violets, which pervaded her apartments. This odor was given off the left half of the chest only and could be obtained concentrated by collecting the perspiration on a handkerchief, heating it with four ounces of spirit, and distilling the remaining mixture. The administration of the salicylate of soda modified in degree this violaceous odor. Hammond also speaks of a young lady subject to chorea whose insensible perspiration had an odor of pineapples; a hypochondriac gentleman under his care smelled of violets. In this connection he mentions a young woman who, when suffering from intense sick headache, exhaled an odor resembling that of Limburger cheese.
Barbier met a case of disordered innervation in a captain of infantry, the upper half of whose body was subject to such offensive perspiration that despite all treatment he had to finally resign his commission.
In lethargy and catalepsy the perspiration very often has a cadaverous odor, which has probably occasionally led to a mistaken diagnosis of death. Schaper and de Meara speak of persons having a cadaveric odor during their entire life.
Various ingesta readily give evidence of themselves by their influence upon the breath. It has been remarked that the breath of individuals who have recently performed a prolonged necropsy smells for some hours of the odor of the cadaver. Such things as copaiba, cubebs, sandalwood, alcohol, coffee, etc., have their recognizable fragrance. There is an instance of a young woman taking Fowler's solution who had periodic offensive axillary sweats that ceased when the medicine was discontinued.
Henry of Navarre was a victim of bromidrosis; proximity to him was insufferable to his courtiers and mistresses, who said that his odor was like that of carrion. Tallemant says that when his wife, Marie de Medicis, approached the bridal night with him she perfumed her apartments and her person with the essences of the flowers of her country in order that she might be spared the disgusting odor of her spouse. Some persons are afflicted with an excessive perspiration of the feet which often takes a disgusting odor. The inguinoscrotal and inguinovulvar perspirations have an aromatic odor like that of the genitals of either sex.
During menstruation, hyperidrosis of the axillae diffuses an aromatic odor similar to that of acids or chloroform, and in suppression of menses, according to the Ephemerides, the odor is as of hops.
Odors of Disease.—The various diseases have their own peculiar odors. The "hospital odor," so well known, is essentially variable in character and chiefly due to an aggregation of cutaneous exhalations. The wards containing women and children are perfumed with butyric acid, while those containing men are influenced by the presence of alkalies like ammonia.
Gout, icterus, and even cholera (Drasch and Porker) have their own odors. Older observers, confirmed by Doppner, say that all the plague-patients at Vetlianka diffused an odor of honey. In diabetes there is a marked odor of apples. The sweat in dysentery unmistakably bears the odor of the dejecta. Behier calls the odor of typhoid that of the blood, and Berard says that it attracts flies even before death. Typhus has a mouse-like odor, and the following diseases have at different times been described as having peculiar odors,—measles, the smell of freshly plucked feathers; scarlatina, of bread hot from the oven; eczema and impetigo, the smell of mold; and rupia, a decidedly offensive odor.
