ROARING IN A HORSE. 
attacked, and very frequently it will go through the 
whole. 
Symptom . — The disease commences with an inflammatory 
attack of the conjunctiva, which is quickly followed by 
opacity of the transparent cornea. Very frequently, but not 
in every case, a white speck will appear in the centre of the 
eye, or near to it, which soon becomes elevated. At the same 
time the internal parts of the eye will become diseased, and 
permanent blindness will sometimes be the result, the eye 
appearing to an ordinary observer to be a mass of purulent 
matter. 
Treatment . — The animal should be placed in a cool and 
dark place ; but not too cold. I very seldom bleed, but give 
a dose of physic, and I find one of the best lotions to be 
applied in the early stage of the disease to be Liquor Plumbi 
Diacetat. well diluted with Aqua Rosse, to which a little Spirit. 
Camphorse is added. If the animal has been neglected, and 
there is a nebula on the cornea, then an astringent lotion is 
called for, and sometimes the use of a rod of nitrate of 
silver is required. 
[In our Journal for last year, p. 555, will be found some 
remarks by us on this peculiar form of ophthalmia in cattle. 
We then said we were not sufficiently acquainted with the 
north of England to speak of the form or character of the 
disease there, and consequently we feel obliged to Mr. Cox 
for his communication.] 
ROARING IN A HORSE, WITH THE SUCCESSFUL 
ADOPTION OF A MECHANICAL CONTRIVANCE 
FOR ITS RELIEF.

I was recently consulted by a medical gentleman upon the 
following case. Some short time previously he had purchased 
a very handsome brougham- horse, but immediately upon 
bringing it home he became sensible of a defect in its 
respiration. Upon examination I at once perceived that the 
horse was a “ roarer,” and about as bad a one as l had seen 
for some time. Not only was the noise distressing, but the 
animal, when in harness, was unable to proceed more than a 
few hundred yards without stopping, while any further 
progression would to all appearance have produced as- 
phyxia.
