(as cooks usually do eggs), till the mixture is like thick cream. 

 This is to be applied to the burned places, spread on cotton or 

 linen rags, for a few days : then the sores are to be dressed with 

 green ^! :tment. (See Ointments.) 



Bursa Mucosa Enlarged.— (See Spavin and Wind Galls.) 



Calculi. — Stone in the bladder. 



Cancer. — This is a hard tumor, malignant in its character, at 

 first small in size, but rapidly increases, and becomes ulcerated. 

 The horse is not affected with so many varieties of cancerous 

 growth as the ox and the dog, and even man himself. Melanotic 

 cancer is most commonly seen in gray horses or those that turn 

 white with age. A small hard tumor is usually seen under the 

 root of the tail and about the anus. 



When tumors of this kind are seen on gray horses, it may rea- 

 sonably be expected that growths of the same character will be 

 found inside, on the spleen, stomach, and liver. Horses so affected 

 may work well for years, and may not for a month. The tumors 

 increase in size ; when cut into, they discharge a fluid as black as 

 the ink of the cuttle-fish. 



Causes. As this disease is not seen in young gray horses until 

 they have almost turned white, it may be inferred that the cause 

 results from the loss or want of the usual pigment, or coloring 

 matter, which gives color to the hair, thus depriving the animal 

 of some protection from the air or sun. I think, however, that 

 the true cause will be found to be, not in the loss of the coloring 

 matter, but of its transfer from the skin and hair to the blood. 

 Hence the inky color of the contents of the tumors. This opinion, 

 which is my own, is still further corroborated by the fact that if 

 the pus be taken from an abscess and injected into the blood of a 

 healthy animal, carbuncles containing pus will soon manifest 

 themselves. 



Treatment. Incurable ; but when one of these tumors breaks, 

 treat it as an ordinary abscess (which see). 



Canine Rabies.— (See Hydrophobia.) 



Capped Elbow. — This is an enlargement on the point of the 

 elbow, just behind the shoulder, and on the side of the chest; 

 sometimes it is in the form of a simple abscess (which see). But
