410 LTMPHITIS. 



Cattse. — Professor Dick is of opinion that the deposit in 

 these cases consists of the dark pigment of the hair. Instead 

 of this pigment beiug distributed to the hair generally, it is, 

 in consequence of some peculiar change arising within those 

 tissues of the skin wherein the pigment in question is secreted, 

 deposited locally as we discover it. 



Theatment. — Deposits of the character above described 

 cannot be treated, in the majority of cases, with any hope of 

 permanent success. If they exist in localities where their 

 presence may not interfere with the usefulness of the animal, 

 it is better to leave them alone, especially if in close contact 

 with important structures— such as the parotid gland, the base 

 of the tongue, or amid the larger vessels and nerves of the 

 neck. A horse affected with Melanosis may be a useful animal 

 for years after the appearance of the deposit. 



LYMPHITIS. 

 Lymphitis is a disease which, although without place in any 

 of our standard veterinary books, is yet, upon the whole, well 

 known, and is designated by a variety of names. In Scotland, 

 for example, it is called Weed; whUe in various parts of England 

 it is known as JPellticJc, Thick Leg, I'arcy, Water Farcy, Sliot- 

 o'- Grease, and a number of other names which it is unnecessary 

 to detail, and which, if detailed, would be impossible to under- 

 stand Twenty years ago a Mr. J, Henderson, V.S., wrote a 

 paper upon this affection, which the reader will find in the 

 ninth volume of The Veterinarian, and from that time to the 

 present it does not appear that our knowledge of its pathology 

 is very greatly increased. 



Symptoms. — The disease generally begins with a shivering 

 fit, though, in many cases, its progress will be so rapid that its
