Nineteenth-century cuppers tended to blame the baths for the low status of cupping among surgeons. Dionis had described the baths in Germany as great vaulted halls with benches on two sides, one side for men and the other for women. Members of both sexes, nude except for a piece of linen around the waist, sat in the steamy room and were cupped, if they so desired, by the bath attendants. The customers' vanity was satisfied by making the scarifications (which left scars) in the form of hearts, love-knots, and monograms.[99] Mapleson's complaint against the baths in 1813 was typical of the reaction of the nineteenth-century professional cupper: The custom which appears to have become prevalent of resorting to these Bagnios, or Haumaums, to be bathed and cupped, appears to have superseded the practice of this operation by the regular surgeons. Falling into the hands of mere hirelings, who practiced without knowledge, and without any other principle than one merely mercenary, the operation appears to have fallen into contempt, to have been neglected by Physicians, because patients had recourse to it without previous advice, and disparaged by regular Surgeons, because, being performed by others, it diminished the profits of their profession.[100] [Illustration: FIGURE 10.--Cupping in the bath, 16th century.

In that period a number of professional cuppers practiced in the cities of Europe and America. Both Guy's and Westminster Hospitals in London employed a professional cupper to aid physicians and surgeons. Of these hospital cuppers, at least four, Thomas Mapleson, Samuel Bayfield, George Frederick Knox, and Monson Hills published treatises on the art of cupping, from which we gain the clearest account of cupping procedure.[101] Knox, who succeeded Mapleson as Cupper at Westminster Hospital, was petitioned by 59 medical and surgical students to write his practical and portable text.[102] _Instruments of the Professional Cupper_ Cupping instruments in the eighteenth and nineteenth centuries were generally simple dome-shaped glass cups provided with thick rims so that the cups would be less painful when applied and removed. Cups were sold in various sizes, ranging from about 45 mm to 75 mm high. Some were made with a smaller diameter and a larger belly for cupping on parts of the body with a limited surface area. For the same reason, cups with an oval rim were recommended. (Figure 11.)
