I 5 DISEASES OF THE DOMESTIC ANIMALS 



ful application of pure phenol on the tip of a toothpick (about 

 which have been wrapped a few strands of absorbent cotton) to 

 the cocainized eye will usually limit its extension. Immediately 

 following this the eye should be flooded with normal salt solution 

 Si to Oi). Paracentesis of the cornea, to liberate pus from it or the 

 anterior chamber, is generally not to be undertaken. 



Opacities of the cornea differ in degree from slight cloudiness 

 (nebulae and maculae) to opaque spots (leucomata). When recent 

 and slight, recovery is more likely to occur. After a year the 

 opacity will be permanent. Daily massage with the yellow oxide 

 of mercury ointment and the instillation of a five per cent, solution 

 of dionin thrice daily are useful in recent cases. Blowing calomel 

 into the eye, once in three days, may be tried if the mercury oint- 

 ment is unsuccessful. If the opacity obscures the pupil iridectomy 

 is indicated. 



In partial staphyloma, bandaging with slight pressure on the 

 eyeball and cutting off the protrusion may succeed in preventing 

 its extension. 



Iridectomy may be indicated. In total anterior staphyloma, 

 enucleation of the eye is in order. 



Laminitis in Horses and Cattle. 



In the horse acute laminitis is commonly caused by concussion, 

 over-exertion, acute indigestion, and bad shoeing, — as by paring 

 away too much of the hoof, or too high calks. It is usually bilateral 

 but is seen in one foot when the animal has had to stand on it owing 

 to lameness of the opposing limb. To obviate this, the shoe of the 

 sound leg should be removed and the patient kept on soft ground, or 

 in slings. 



Symptoms. — When in both fore feet, there is great lameness 

 and difficulty in movement. The fore feet are outstretched and 

 are hot and painful on tapping the soles. In many cases the animal 

 may refuse to stand. If the hind feet are attacked the animal
