Rayer saw a Piedmontese of twenty-eight, with an athletic build, who had but little beard or hair on the trunk, but whose scalp was covered with a most extraordinary crop. It was extremely fine and silky, was artificially frizzled, dark brown in color, and formed a mass nearly five feet in circumference.
Certain pathologic conditions may give rise to accidental growths of hair. Boyer was accustomed to quote in his lectures the case of a man who, having an inflamed tumor in the thigh, perceived this part becoming covered in a short time with numerous long hairs. Rayer speaks of several instances of this kind. In one the part affected by a blister in a child of two became covered with hair. Another instance was that of a student of medicine, who after bathing in the sea for a length of time, and exposing himself to the hot sun, became affected with coppery patches, from which there sprang a growth of hair. Bricheteau, quoted by the same authority, speaks of a woman of twenty-four, having white skin and hair of deep black, who after a long illness occasioned by an affection analogous to marasmus became covered, especially on the back, breast, and abdomen, with a multitude of small elevations similar to those which appear on exposure to cold. These little elevations became brownish at the end of a few days, and short, fair, silky hair was observed on the summit of each, which grew so rapidly that the whole surface of the body with the exception of the hands and face became velvety. The hair thus evolved was afterward thrown out spontaneously and was not afterward reproduced.
Anomalies of the Color of the Hair.--New-born infants sometimes have tufts of hair on their heads which are perfectly white in color. Schenck speaks of a young man whose beard from its first appearance grew white. Young men from eighteen to twenty occasionally become gray; and according to Rayer, paroxysms of rage, unexpected and unwelcome news, diseases of the scalp such as favus, wounds of the head, habitual headache, over-indulgence of the sexual appetite, mercurial courses too frequently repeated, too great anxiety, etc., have been known to blanch the hair prematurely.
The well-accepted fact of the sudden changing of the color of the hair from violent emotions or other causes has always excited great interest, and many ingenious explanations have been devised to account for it. There is a record in the time of Charles V of a young man who was committed to prison in 1546 for seducing his girl companion, and while there was in great fear and grief, expecting a death-sentence from the Emperor the next day. When brought before his judge, his face was wan and pale and his hair and beard gray, the change having taken place in the night. His beard was filthy with drivel, and the Emperor, moved by his pitiful condition, pardoned him. There was a clergyman of Nottingham whose daughter at the age of thirteen experienced a change from jet-blackness of the hair to white in a single night, but this was confined to a spot on the back of the head 1 1/2inches in length. Her hair soon became striped, and in seven years was totally white. The same article speaks of a girl in Bedfordshire, Maria Seeley, aged eight, whose face was swarthy, and whose hair was long and dark on one side and light and short on the other. One side of her body was also brown, while the other side was light and fair. She was seen by the faculty in London, but no cause could be established.
Voigtel mentions the occurrence of canities almost suddenly.
Bichat had a personal acquaintance whose hair became almost entirely gray in consequence of some distressing news that reached him. Cassan records a similar case. According to Rayer, a woman by the name of Perat, summoned before the Chamber of Peers to give evidence in the trial of the assassin Louvel, was so much affected that her hair became entirely white in a single night Byron makes mention of this peculiar anomaly in the opening stanzas of the "Prisoner of Chillon:"--"My hair is gray, but not with years, Nor grew it white In a single night.
As men's have grown from sudden fears."
The commentators say that Byron had reference to Ludovico Sforza and others. The fact of the change is asserted of Marie Antoinette, the wife of Louis XVI, though in not quite so short a period, grief and not fear being the cause. Ziemssen cites Landois' case of a compositor of thirty-four who was admitted to a hospital July 9th with symptoms of delirium tremens; until improvement began to set in (July 13th) he was continually tormented by terrifying pictures of the imagination. In the night preceding the day last mentioned the hair of the head and beard of the patient, formerly blond, became gray. Accurate examination by Landois showed the pigment contents of the hair to be unchanged, and led him to believe that the white color was solely due to the excessive development of air-bubbles in the hair shaft. Popular belief brings the premature and especially the sudden whitening into connection with depressing mental emotions.
