According to Dupont, this hyperidrosis was independent of any other affection, and after having been combated fruitlessly by various remedies, yielded at last to fluid extract of aconitin.
Myrtle relates the case of a man of seventy-seven, who, after some flying pains and fever, began to sweat profusely and continued to do so until he died from exhaustion at the end of three months from the onset of the sweating.

Richardson records another case of the same kind.
Crocker quotes the case of a tailor of sixty-five in whom hyperidrosis had existed for thirty-five years.

It was usually confined to the hands and feet, but when worst affected the whole body.

It was absent as long as he preserved the horizontal posture, but came on directly when he rose; it was always increased in the summer months.

At the height of the attack the man lost appetite and spirit, had a pricking sensation, and sometimes minute red papules appeared all over the hand.
