instruments have now become obsolete; nor are the others always used in combination, but more frequently singly. These statements were collected by Vergari from the observations of the most intelligent physicians and surgeons in Apulia, and other districts of the former kingdom of Naples. De Renzi, a distinguished physician of Naples, sent, in the year 1841, to the 'Raccoglitore Medico,' published in Fano, the following account of a Tarantism witnessed by Doctor Samuele Costa. Giuseppe Mastria, a peasant from a small village in the southern district of the province Terra d'Otranto, twenty years of age, of robust bodily constitution, while mowing grass, in June, 1840, felt a sudden pain on his right arm, near the insertion of the Deltoid muscle, and saw that he was bitten by a speckled spider, the Aranea Tarantula. The wound having become livid, enlarged and spread the pain over the arm and the back of the neck. He was seized with anxiety and with pressure on the Praecordia, inclination to vomit, faintness, cold skin, and weak pulse. After some time, the warmth of the body increased, and the pulse became stronger. The patient experienced great thirst, heavy breathing, restlessness, and the impossibility of standing on his legs. When, however, the Tarantella was played to him, he suddenly became convulsive, jumped out of the bed, and danced briskly for nearly two hours. Tired and profusely perspiring, he consequently slept quietly and uninterruptedly. After several repetitions of the music in the course of three days, he entirely recovered.[64] Dr. Martinus Kaehler, a Swedish physician, who visited Apulia in the year 1756, for the express purpose of investigating the Tarantism thoroughly, came to the conclusion that it is not caused by the Tarantula, but that it is a peculiar hypochondria with hysteria, to which the inhabitants of the island of Taranto are especially subject on account of their mode of living, and from their food consisting principally of green vegetables, oysters, and periwinkles. Be this as it may, the complaint is, according to medical opinion, curable by means of music and dancing. Thomas Shaw, who visited the Barbary States about the year 1730, mentions the _Boola-kaz_, a venomous spider in the desert of Sahara, the bite of which is cured thus: "The patient lies sometimes buried all over, excepting his head, in the hot sands, or else in a pit dug and heated for the purpose, in order, no doubt, to obtain the like copious perspiration that is excited by dancing in those who are bitten by the Tarantula."[65]
