[150] Patent specifications, U.S. patent 4705; TIEMANN & CO., op. cit. [note 144], page 115. Tiemann was awarded an earlier patent for a scarificator in 1834 (unnumbered U.S. patent, 26 August 1834), which seems to have employed a coiled spring similar to that found in the Charrière scarificator. The fifth U.S. patent for a scarificator was issued in 1846 to A. F. Ahrens of Philadelphia (U.S. patent 4717) for a circular scarificator in which all the blades were attached to a movable plate.

Blisters were substances (including mustard and cantharides) that when applied to the skin, occasioned a serous secretion and the raising of the epidermis to form a vesicle. Cautery was the application of a red-hot iron to the skin. A seton was a long strip of linen or cotton thread passed through the skin by a seton needle. Each day a fresh piece of thread was drawn through the sore. Moxa were cones of cotton wool or other substances which were placed upon the skin and burned.
