FOUND IN THE EYES OF HORSES IN INDIA. 109 



Dr Berry, howevei*, who has frequently succeeded in extract- 

 ing them, informs me that he has not only often met with 

 them considerably longer than I have described, but also that 

 upon his placing them in a tumbler of tepid water, he has seen 

 them swim about for several minutes, and even for a quarter 

 of an hour ; and that when viewed in this situation, the shape 

 evidently appears to taper off towards the tail. Had I thought 

 of placing those which I have met with, as Dr Berry did, in 

 tepid water, it seems not improbable, that I might both have 

 found some of them alive, and also of greater length, than 

 when viewed under exposure to the open air. 



Upon this occasion, it is both proper and satisfactory to re- 

 fer to the testimony of that eminent naturalist, the late Dr 

 James Anderson of Madras. Having had occasion, several 

 years ago, to mention this worm, and the disease which it oc- 

 casioned in the horse's eye, to one of his scientific correspon- 

 dents, it is believed to Dr Rush of Philadelphia, his letter was 

 at the time given to the public, in one of the Madras newspa- 

 pers. Though Dr Anderson's correspondence was afterwards 

 collected from the newspapers, and reprinted, it might now be 

 difficult to find a copy of it. But I recollect to have heard af- 

 terwards, that the letter now alluded to, had been communica- 

 ted by Dr Anderson's correspondent to the American Philo- 

 sophical Society. I remain, &c.
