286 Account of a Filaria in a Horse's Eye. 



small forceps. In a second case the conjunctiva was more in- 

 flamed, and the patient refused to submit to an operation. In 

 Blot's case above-mentioned, -the worms were between the con- 

 junctiva and the cornea, around and across which they traversed, 

 producing stinging pains and nervous symptoms. The patient, 

 an African negress, was unable to tell where she came from, or 

 whether her fellow-country people were subject to similar affec- 

 tions. The Cystericus cellulosa has also often been observed in 

 the human eye, of which there is a case in the London Medical 

 Gazette for Aug. 1833, where one was seen in the eye of a little 

 girl six years old, under the conjunctiva resting on the sclerotica, 

 and perfect in all its parts. 



The existence of Filaria in the eyes of horses in the East In- 

 dies, is of frequent occurrence, as may be seen by consuhing an 

 article in the Edinburgh Medical and Surgical Jour7ial for Jan. 

 1826. Bremser states that he saw three worms in the anterior 

 chamber of the eye of a horse at the Veterinary School of Vien- 

 na, in 1813. In the Bulletin des Sciences Medicates for Feb. 

 1826, it is stated that Dequilleme saw several of these animals in 

 the eye of a cow, and the case was published by Gohier, a vet- 

 erinary teacher, in his memoirs. In the report of the proceedings 

 of the Veterinary School at Lyons, in 1822, there is a case in 

 which a knot of worms was seen in the eye of a mule. Some 

 of these were extracted ; no inflammation followed the operation, 

 but a violent nervous agitation of the head and a turning of it to 

 the left side, took place. In the same journal mention is made of 

 a memoir read before the Medical Society of Calcutta, in which 

 the writer states that the iStrojigylus ai^tnatus niitior of Rudolphi, 

 - and the Filaria papillosa are frequently found in the eyes of horses 

 in India, but much more so in the cellular membrane, particularly 

 about the loins. The writer maintains that they make their way 

 into the blood-vessels, and through them into the eye. Treutler 

 says that he has seen the Sti^ongylus armatus in aneurisms.of the 

 mesenteric artery of the horse, and Dr. Kennedy, in the Edin- 

 burgh Phil. Transactions, describes a worm which he calls Asca- 

 ris pellucidus, but which was doubtless the Filaria papillosa, 

 as being common in the eyes of horses in the east. A common 

 effect of these worms in the muscles of the loins is paralysis of
