VII. Account of a non-descript Worm (the Ascaris pellucidus) found in the Eyes of Horses in India. In Letters from Alexander Kennedy, M. D. F. R. S. Edin. to Professor Russel and Dr Hope. With a Description of the Animal

Extract

When I lately mentioned to you in conversation, the disease in the eyes of horses in India, occasioned by the presence of a worm within the ball of the eye, I thought that you might probably have heard of it before; but as you had not, and are desirous of further information upon the subject, I now take this method of mentioning the circumstances to you, so far as I know them.

The animal occasioning this disease, is termed by the natives about Madras, the “Worm” in the Horse's Eye, by using the corresponding words in their respective languages. I have been told that in Bengal it is called the “Sānp” or the Snake in the Horse's Eye. As it seems more to resemble a fish or an aquatic insect, it might perhaps with more propriety be regarded as an eel.
