For JUNE, 1795. Account of the TARANTULA. T HE Tarantula is of the Spider Genus, and has eight legs, with three joints in each, terminating in three crooked Claws; and ei, ht eyes. The breaft and belly are of an fh colour, with blackish rings on the under part; the fangs or nippers are red on the inner fide, the rest being blackith Two of its eyes are larger than the other, red, and placed in the front; four other eyes are placed in a tranfverfe direction towards the mouth; the other two are nearer the back: It has two anteni æ or feelers. It is a native of Italy. Cyprus, Barbary, and the Eaft Indies. It lives in bare fields, where the lands are fallow, but not very hard; and frɔm ite antipathy to damp and fhade, caoufes for its reûR dence dence the rifing part of the ground facing the eaft Is dwelling is about four inches deep, and half an inch wide; at the bottom it is curve, and there the infect fits in wet weather, and cuts its way out if water gains upon it. It weaves a net at the mouth of the hole. These fpiders do not live quite a year, In July they fhed their skin, and proceed to propagation; which, from a mutual dittruft, as they trequently devour one another, is a work undertaken with great circumfpeétion. They lay about teven hundred and thirty eggs, which are hatched in the spring; but the parent does not live to fee her progeny, having expired early in the winter. The Ichneumon fly is their most formidable enemy. The bite of the Tarantula is faid to occafion an inflammation in the part, which in a few hours brings on ficknets, difficulty of breathing, and univerial faintnets. The perfon afterwards is affected with a delirium, and fometimes is feized with a deep melancholy. The fame fymptoms return annually, in fome cafes, for several years; and at last terminate in death. Mufic, it has been pretended, is the only cure. A mufician is brought, who tries a variety of airs, till at last he hits upon one that urges him to dance; the violence of which exercise produces a proportionable agitation of the vital fpirits, attended with a confequent degree of perfpiration, the certain confequence of which is a cure. Such are the cir 'cumstances that have been generally related, and long credited, concerning the bite of this animal. Kircheras, in his Mafurgia, gives a very particular account of the fymptoms and cure, illuftrated by hiftories of cafes. Among thele, he mentions a girl, who being bitten by this infect, could be cured only by the music of a drum. He then proceeds to relate |
