The Tarentula Cubensis, the hairy spider, causes a perfect picture of carbuncle even to the sloughing. It may be used effectually when there are great prostration and diarrhoea with intermitting fever of evening exacerbation. In relieving the atrocious pains accompanying this condition, it acts almost like magic. It should therefore be compared with LACHESIS, ANTHRACINUM, and SILICEA.
