o30 THE NATURE AND TREATMENT OF 



PARASITES AROUND AND WITHIN THE GLOBE Oh 

 THE EYE. 



A species of parasite, commonly known as worms, are oc^ » 

 sionally the habitants of the tissues entering into the composi 

 tion of the coverings of the eye, and once in a while they 

 make their appearance within the globe. The only local 

 remedy, of any value is, infusion of lobelia, prepared as 

 follows : — 



Lobelia Seeds 1 ounce. 



Boiling Water, 1 quart. 



Let the mixture stand until cool, then pour off the clear 

 liquor, and occasionally bathe the eye with a portion of the 

 same ; in the mean time let the patient have a dose or two 

 of sulphur and sassafras, equal parts. Dose, one ounce, to be 

 incorporated with the food. 



According to BaiUet, these worms belong to the genus fila- 

 riae (the same are often found in the air passages of sheep). 

 Naturalists consider them as gregarious, being found in num- 

 bers of nine — eight females and one male. The filariae are 

 thus described by Mr. Gamgee. 



" M. Serres has often found them under the eyelids of the 

 ox. I had an opportunity to study their characteristics, in six 

 females found by M. Lafosse, under the eyelid of a cow, in 

 1855. From that time, though some details of their organi- 

 zation were still wanting, I considered them as belonging to 

 the genus filariae, and I designated them, in my course of lec- 

 tures, the Jilarice boviss There can be no doubt as to the 

 j>lace which these worms are to occupy in our classification. 



"The slender, filiform, and elongated body; the defined 

 mouth, without papillae; the almost terminal anus ; the double 

 ovaries, united in one common oviduct, which is situated 

 at a little distance from the extreme end of the anterior ex- 

 tremity ; and the embryons, which are notched in the interior 

 of the tubes of the oviduct, all show that these nemato'ides 

 belong to the genus filariae. The name o^ jilarice. bovis may 

 not be a proper one, as there are other filariae found in these 

 animals, and, therefore, an inconvenience might arise from its
