SWELLING OF THE LEGS. — (Anasarca.) 



This is a species of dropsy, which shows itself in the legs of 

 horses ; and sometimes the tumefaction extends to the sheath, 

 and along the abdomen, as far as the pectoral muscles. The 

 swelling generally appears towards morning, after a night's rest, 

 and disappears again after a few hours' work. 



Ordinarily, the hind limbs are the most prone to become ana- 

 sarcous ; except in cases of effusion into the whole cellular tis- 

 sues of all the limbs — such as we observe in general dropsy, 

 or when the subject is laboring under an attack of influenza, 

 "pink-eye," &c. 



Cullen enumerates five species of anasarca, viz. : — 



1. Anasarca serosa ; as when the due discharge of the serous 

 or watery matter of the blood is suppressed, &c. 2. Anasarca 

 oppileta, as when the blood vessels are considerably pressed 

 during pregnancy, &c. 3. Anasarca exanthemata ; this happens 

 after ulcers, and various eruptive disorders. 4. Anasarca anos- 

 mia happens when the blood is extremely poor, from considerable 

 losses of it. And, 5. Anasarca debilium ; as when feebleness is 

 induced by long illness. The last three are the kinds we gener- 

 ally have to contend with in veterinary practice. 



Anasarca exanthemata appears simultaneously with farcy, (or 

 disease of the superficial absorbents,) and in various cutaneous 

 eruptive diseases. A swelling sometimes appears in the lower 

 parts of the legs, (which feel hot,) and occasions to the animal 

 a sense of itching, and an acute pain, whenever the part receives 

 pressure ; although at other times there appears little or no pain. 

 At length a serous fluid discharges itself through the cutaneous 

 vessels, or pores of the skin, corroding the skin, and finally ends 

 in the disease termed " grease."
