In different parts of the world, the water drank is accused of occasioning intestinal worms, as the tænia in Switzerland, and the tænia and the teretes in the West Indies; where, likewise, I have heard the mucilaginous vegetables eaten assigned as a cause of the frequent appearance of worms. In Russia, there is a worm, the lumbricus militensis, common near swampy grounds. In Russia and in Siberia, in the same situations, the tænia infernalis prevails. But, after what has been here stated, we cannot bring the water, drank on board the Minerva, or at Bombay, to account for the Guinea-worm which prevailed: in fact, the water came from different and distant quarters, Bombay, Ceylon, and Madras. Besides, the officers of the 38th, and the artillery, drank the same water, and escaped. No case of Guinea-worm had been known among either the Lascars or European sailors in the Minerva, when the 86th and 88th embarked in her. I have good reason to think that the spreading of the Guinea-worm may be stopped, whenever it does appear. The means which we adopted appeared to succeed. Extreme attention to cleanliness is indispensably necessary. In India, the native doctors are much more successful in getting out the worms, than Europeans. After long feeling with their fingers, for the body of the worm, they make an incision as nearly as they can judge over its middle, and, pulling the worm by a duplicature of it, draw out both ends of the worm at one time. I have often endeavoured to imitate this practice. My sense of touch was not so delicate, and did not guide me so correctly, as it did the Hindoo doctors; but I always found that when, on cutting down to it, I got on the middle of the worm, and, by the forceps, pulled this out, I could with ease extract a large portion, and, not unfrequently, the whole worm.
