had several cases under treatment of late. These, fortunately, have all done 

 well. Recurrent ophthalmia depends upon constitutional disturbance, 

 induced by malhygienic conditions. Heredity is also a potent factor in 

 predisposing to this disease. One should always bear this in mind, as no 

 animal subject to it should be used for stud purposes. It has been noticed 

 that animals bred in low-lying damp districts, are more liable to contract 

 recurrent ophthalmia, than those living in healthy well-drained districts. 



As a rule, this disease attacks one eye only, and the pupil of the 

 disordered visual organ at first is seen to be contracted. It usually comes 

 on very suddenly. There is no difficulty in distinguishing it from simple 

 ophthalmia, to which affection it bears a general resemblance, from the fact 

 that the whole eye being involved in the recurrent form, the inner parts 

 assume a dull yellowish clouded aspect. An attack of recurrent ophthalmia 

 runs through its acute stage in about eight days. The inflammation then 

 abates somewhat, and the animal becomes a little more tolerant of light ; 

 but a relapse, even when the best therapeutic measures have been adopted, 

 will nevertheless sometimes occur, and the eye becomes almost or quite as 

 bad as before. In the general way, about a couple of months elapses 

 between each attack, but in the interval the eye is not restored to its normal 

 condition. Unless cured, the relapses become frequent, and the disorgani- 

 sation of the eye becomes so complete, as to cause total blindness. The 

 first attack of recurrent ophthalmia is generally the most severe, and its 

 symptoms the most intense. The eyelids become very inflamed and red, 

 and the animal cannot bear to open them, or allow his head to be touched. 



Early and judicious treatment is absolutely essential in treating 

 recurrent ophthalmia. A dose of aloes should be given in the first instance, 

 and the animal should be confined in a large, darkened, loose airy box, and 

 fed upon laxative diet. Internally, a drench, containing liquor ammonii 

 acetatis four ounces, bicarbonate of potassium half an ounce, and spirit of 

 nitrous ether one ounce, may be given in several ounces of water three 

 times daily. Locally, a few drops of a lotion of four grains of sulphate of 

 atropine to an ounce of water, should be placed in the corner of the affected 

 eye, three times daily. In the region of the head, behind the ear, a seton 

 should be placed ; or, if this be not done, the same part may be thoroughly 

 blistered with a mixture of ointment of cantharides and of biniodide of 

 mercury. The food should be of a more nutritious kind, after the acute stage 

 is over, and the drenches may then also be discontinued. These measures 

 are generally effectual in curing the complaint. 'Should a relapse occur, the 

 same steps must be repeated. The treatment sometimes carried out in this 

 affection is very strange, and founded Oii no scientific principles. 



AMAUROSIS AND CATARACT. 



IjV amaurosis, we understand an affection of the eye in which the organ 

 assumes a glassy appearance. It is frequently caused by derangement of 

 the optic nerve, which expands to form the retina or nervous layer of the
