inflammation, especially of the face and hands, attended with itching,
redness, burning and swelling, with watery blisters.

Treatment: Give saline laxatives, and apply weak lead and laudanum,

violent vomiting and sometimes purging, with great prostration.

follow with an active emetic; then give chloroform in teaspoonful doses,
in flour and water or glycerine, every few minutes while the spasms
last, and afterwards brandy and stimulants, and warmth of the
extremities if necessary. Recoveries have followed the free and prompt
