probably the result of some morbid state of the 

 blood. It may affect only one side or both. Symp- 

 toms: It is usually ushered in by slight or severe 

 chill, followed by fever, quick and painful breath- 

 ing, interrupted by a short cough, almost continu- 

 ous. The animal is restless and if made to move 

 will evince pain and stiffness, which may be taken 

 for founder. The difference can be easily detected 

 by the pulse, which in pleurisy is small and hard, 

 while in founder it is full and soft. On backing the 

 horse, if it is pleurisy it will lift its fore feet al- 

 though it may give it pain; if founder, it will not 

 lift its fore feet from the ground, and if forced will 

 drag its feet, and arch its back, have its hind feet 

 forward under its belly. The expulsion of the 

 breath is principally done by the muscles of the 

 abdomen, and the ribs kept as fixed as possible. 

 There is a depression or line running along the 

 cartilage of the false ribs. This is well marked, 

 even in the early stages of the disease. The ani- 

 mal will look around at its side or sides, and show 

 signs of colic, but will rarely lie down. If made to 

 move suddenly will grunt. On applying the ear to 

 the sides you will hear a grating sound every time 

 the animal breathes. This is caused by the dry, 

 inflamed surfaces rubbing together. After a few 

 days, friction sound passes away, and we either 

 hear no sound or we may be able to hear the sound 

 of fluid. At this time, if the pulse becomes small 

 and fast and the breathing is more heaving, there 

 is danger of effusion taking place. At this time, if 

 effusion has taken place, on applying the ear to the
