not much hope of recovery may he expected. Cures, however, 

 liave been made by drawing off the fluid b}^ means of a trocar 

 pierced through between the ribs into the chest. 



(5.) Adhesions. — The surface of the lungs becomes attached to 

 the sides of the chest by fibrous bands of great strength, another 

 common result of pleurisy. Nothing can be done but to keep up 

 tlie liealth and strength by good feeding, etc. 



When animals do not thrive and pick up their spirits and flesh 

 after pleurisy, some of these various conditions may be reasonably 

 exjiected to be present.

 or whisky.

 cut surfaces, after bleeding has stopped, and forms the medium by 

 which the parts adhere, and are joined together. In this instance

Lymphangitis. — This is a disease which attacks large coarse- 

 bred horses that are difficult to keep in good condition, and con- 

 sists in the outpouring of plastic lymph into the femoral veins of 

 one of the fore legs, which, as a consequence, swells to a very
