animal, and continuously apply cold water to the affected 

 feet. 



Conjunctivitis, Simple ophthalmia. — Results from injuries 

 and from entry of foreign matter into the eye. The eye is 

 red and congested, tears flow freely from it and the patient 

 cannot bear exposure to the light. Seek and remove the' 

 cause. Then bathe the eye freely with cold water. Follow- 

 ing this, put into ihe eye a few drops of alum or zinc or 

 boric lotion (see collyria under Recipes). If any opacity of 

 the cornea should result, dress the eye with silver nitrate 

 lotion — 5 grains to an ounce of water. 



Worm in the eye. — The worm is Filaria lachrymalis. It 

 does not, as in the horse, live within the aqueous chamber of 

 the eye but on the surface of the cornea, and lodges at 

 the inner angle under the haw. There may be one worm or 

 several. The affected eye is partially closed and continually 

 waters. Cast the animal and bathe the eye freely with cold 

 water. The worms, if present, can be got at by lifting up the 

 haw. They must be picked up with forceps and removed. 



Paralysis. — This is characterized by total or partial loss 

 of sensibility or motion or both in some part or parts of the 

 body. The most usual form in which the disease is met 

 with in cattle, is the affection of the hind quarters known as 

 paraplegia. Causes are injuries to the spine, overloading (in 

 pack bullocks), sudden changes of temperature and exposure 

 to wet and cold. The animal is unable to move freely, and 

 drags the hind quarters. The gait is unsteady and staggering. 

 Give a purgative to clear out the bowels. Apply a blister of 

 red iodide of mercury to the loins (see Irritants under 

 Recipes) and give daily for about a month half a dram of 

 powdered nux-vomica in food or as drench. 



Milk fever : parturient apoplexy ; dropping after calving. — 

 A disease peculiar to the cow which occurs after calving 

 and within 10 days of it. In rare instances it is seen during 

 or immediately prior to the birth of the calf. The disease is 

 one of the nervous system and induces a partial or total loss 

 of power. It is due to the formation of a certain ferment or 

 toxin (poison) in the udder, which is absorbed and causes 

 this nervous disorder. It chiefly affects deep milkers, and 

 one attack predisposes to a second. The animal has a wild 

 look and the gait is staggering. It lies in a state of torpor 

 and moans. There is no discharge of dung or urine. The 

 mouth opens and saliva flows from it. If any gruel is given, 

 it runs out of the mouth without the cow making any 

 attempt to swallow it. The disease is very fatal. Its
