Albucasis recommends us to fasten to the end of the animal a piece of lead from one to two drs. in weight, and thereby to extract it gradually. He says that in some cases the animal is as long as fifteen palms, nay, that he had seen one twenty palms long. Rhases says that the dracunculus takes place in hot and squalid bodies, and is formed by the use of potherbs and fruits. He recommends gradually increased doses of aloes, and when the animal protrudes it is to be wrapped round a leaden reed one dr. in weight, so that it may be dragged out gradually. He cautions us not to leave any part of it in the body. He also approves of incision as described by our author. In his ‘Continens’ he collects the opinions of Galen, Paulus, and others. He says that it forms most commonly in the bodies of persons who bathe frequently, and drink much wine. He says that he had seen it extracted by making free incisions. See an interesting account of the guinea-worm in No. 66 of the ‘Edinburgh Medical and Surgical Journal,’ by Mr. Scott, surgeon, Madras. Bertapalia, Guy of Cauliac, and all the early modern writers on medicine, repeat the ancient accounts of the vena civilis vel medine. They direct us to extract it by attaching a small piece of lead to its extremity. Ambrose Paré adopted Galen’s notion, that it is corrupted animal matter; but Andry held that it is a real animal. It appears, however, from some statements which we have seen in the periodicals of the day, that some of our English surgeons in the East Indies still advocate the doctrine of Galen; but we are inclined to think that the other opinion is the more correct one.
