Such instruments are not, however, entirely unknown in Europe. In France, in the eighteenth century, it appears that rings, sometimes set with hard knobs, and called "aides," were occasionally used by men to heighten the pleasure of women in intercourse. (Dühren, _Marquis de Sade_, 1901, p. 130.) In Russia, according to Weissenberg, of Elizabethsgrad, it is not uncommon to use elastic rings set with little teeth; these rings are fastened around the base of the glans. (Weissenberg, _Zeitschrift für Ethnologie_, 1893, ht. 2, p. 135.) This instrument must have been brought to Russia from the East, for Burton (in the notes to his _Arabian Nights_) mentions a precisely similar instrument as in use in China. Somewhat similar is the "Chinese hedgehog," a wreath of fine, soft feathers with the quills solidly fastened by silver wire to a ring of the same metal, which is slipped over the glans. In South America the Araucanians of Argentina use a little horsehair brush fastened around the penis; one of these is in the museum at La Plata; it is said the custom may have been borrowed from the Patagonians; these instruments, called _geskels_, are made by the women and the workmanship is very delicate. (Lehmann-Nitsche, _Zeitschrift für Ethnologie_, 1900, ht. 6, p. 491.) It is noteworthy that a somewhat similar tuft of horsehair is also worn in Borneo. (Breitenstein, _21 Jahre in India_, 1899, pt. i, p. 227.) Most of the accounts state that the women attach great importance to the gratification afforded by such instruments. In Borneo a modest woman symbolically indicates to her lover the exact length of the ampallang she would prefer by leaving at a particular spot a cigarette of that length. Miklucho-Macleay considers that these instruments were invented by women. Brooke Low remarks that "no woman once habituated to its use will ever dream of permitting her bedfellow to discontinue the practice of wearing it," and Stevens states that at one time no woman would marry a man who was not furnished with such an apparatus. It may be added that a very similar appliance may be found in European countries (especially Germany) in the use of a condom furnished with irregularities, or a frill, in order to increase the woman's excitement. It is not impossible to find evidence that, in European countries, even in the absence of such instruments, the craving which they gratify still exists in women. Thus, Mauriac tells of a patient with vegetations on the glans who delayed treatment because his mistress liked him so best (art. "Végétations," _Dictionnaire de Médecine et Chirurgie pratique_).
