(} to 1 per cent.), permanganate of potash (0'05 per cent.), 
and salicylic acid (1 per cent.). 
Dry calomel or tannoform blown or dropped on the 
eyeball in small quantities is favoured by some prac- 
titioners. 
In all eye cases which are characterised by marked 
photophobia and sensitiveness, 2 drachms of liq. opii sed. 
may be added to each ounce of the zinc or boric lotions 
mentioned above, and the combination will be found a 
very excellent sedative and astringent eye-wash.. 
If the pain is intense, mv. of a2 to 5 per cent. solution 
of cocaine hydrochlor., dropped into the eye, will pro- 
duce complete insensitiveness in a few minutes, lasting, 
however, not much more than ten minutes. It may 
be repeated as required, or cocaine ointment could be 
smeared on the eyelids at frequent intervals. 
Unless severe ocular irritation is relieved, we often find 
the dog scratching at its eyes or rubbing them at every 
opportunity, with the result that ¢raumatic ulcers or 
wounds are not infrequently produced. To obviate 
such a contingency, shields of various kinds have 
been devised, but unless they are perfect in fit and 
comfortable to wear, they usually cause more harm than 
good, and worry the dog incessantly. Subdued light is 
an advantage where photophobia exists, and if the 
animal can be kept in a darkened room while the eye 
trouble is at its height, no shield or bandage will be 
found necessary. 
Keratitis.—For the treatment of parenchymatous keratitis 
frequent bathing with warm antiseptic solutions will 
materially contribute to the reduction of inflammation, 
and other treatment may be prescribed as for conjunc- 
tivitis, whilst, in addition, a half per cent. solution of 
atropine sulph. is ver'y useful.
