OTHER DISEASES CF THE EYE. 161 



When this terminatior. threatens, the globe of the eye will usually 

 turn to a bottle-green color, then ulceration will appear about the 

 centre of it, and the eye will become of three or four times its 

 natural size, or it will gradually diminish and sink into the orbit. 



The fluid discharged from it will be so acrid that it will excoriate 

 the parts over which it runs, and the hds will become swollen and 

 ulcerated. 



The most humane method to be adopted with regard to the an'- 

 mal, is to remove the eye. If the owner does not think proper to 

 adopt this, let him try to make the beast as comfortable as he can. 

 The part should be kept clean, and whi^n there appears to be any 

 additional inflammation, or swelling, or pain, the eye should be well 

 fomented with a decoction of poppy-heads. 



Homoeopathic treatment. — The cure is easily efi'ected, when the 

 case is taken in time ; commence with a few doses of aconitum, 

 which is to be employed at first from hour to hour ; then at longer 

 intervals. Resort afterwards to arnica. If it be too late, conium 

 must be given, which is also indicated when aconitum and arnica 

 have removed the inflammatory symptoms, but there is an exudation 

 between the laminae of the cornea. Cannabis, belladonna, or euphra- 

 sia, in two ounces of distilled water, form an excellent topical appli- 

 cation ; but they should also be used internally. If the ophthalmia 

 has been occasioned by a foreign body in the eye, it calls for a dif- 

 ferent treatment. Extract the foreign body with a bit of moistened 

 linen ; conium then removes the symptoms, and if there have been 

 any injury, arnica should be prescribed, both externally and inter- 

 nally. Ophthalmia caused by cold soon yields to aconitum, hryonia^ 

 dulcamara, and euphrasia. 



When the disease proceeds from an internal cause and is peri- 

 odical, it is hereditary, or depends on the deposition on the eye of 

 a morbific principle difficult to be determined. The chief means 

 to be employed are sulphur, euphrasia, pulsatilla, cannabis, conium, 

 and causticum. Belladona might also be tiied. Calcarei carbonica 

 is useful in the case of turbid vision with a bluish tint of the cornea 

 — the lids not being aff'ected. 



OTHER DISEASES OF THE EYE. 



There is a singular disease of the eye, not properly ophthalmia, 

 sometimes epizootic among cattle, that sadly frightens the owner 

 when it first appeal's. Young cattle pasturing on wet and woody 

 ground are suddenly seized with swellings of the tongue and throat, 

 and eruptions about the membrane of the mouth, and the eyes be- 

 come intensely inflamed, and superficial ulcers appear on the cornea. 

 This is only one of nature's methods, singular indeed, of getting rid 

 of something that off'ended the constitution ; and tl:e way is to let 

 iier nearly alone. The skillful practitioner foments with warm water,
