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 tule, 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 judiciots 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 on no scientific principles. 
AMAUROSIS AND CATARACT. 
By 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
