Sinking of one eye indicates local atrophic disease. 

 The expression of the face is usually altered in acute disease. 

 Anxiety and distress are easily discerned in our patient. 



Terror is shown by the expression of the face. Young 

 animals brought suddenly into contact for the first time with 

 the sights and sounds of city life are very much alarmed and 

 terrified by unusual experiences. I have seen a young horse 

 frightened to death, one 17th of March, by a brass band. 



Rage is very easily seen in hydrophobia and some other 

 diseases. 



What has been said already on General Semeiology will 

 be sufficient for the plan pursued in this unpretending work, 

 with the exception of a few words on physical diagnosis. 



PHYSICAL DIAGNOSIS. 



By this means we determine the actual and relative posi- 

 tion, material condition and functional action of the different 

 organs contained within the body. 



There are at least six modes of examination of the thoracic 

 and abdominal cavities, but for all practical purposes two 

 are sufficient, percussion and auscultation. 



By percussion we learn much of the physical condition 

 of such organs as the lungs, heart, and abdominal viscera, 

 through the variations of resonance and resistance when the 

 walls of the thorax or abdomen are lightly struck. 



Auscultation is equally important, but somewhat more 

 difficult in its application on account of the complexity of 

 sounds afforded by it ; this is especially true in cattle prac- 

 tice, but is not so difficult in diseases of the horse. It con- 

 sists in direct listening to the sounds produced within the 

 cavities of the body, by placing the ear, with or without an 

 instrument, upon the surfaces thereof. 



General expansion, or local bulging, and general re- 

 traction and local depression, are the signs most frequently 

 noticed in the following diseases. 



Retraction, or local depression of the thoracic walls, 

 may result from : 



Absorption of pleuritic effusion. 

 Tuberculization. 

 Pneumonia. 

 Pleuro-pneumonia. 

 Infiltrated cancer of the lungs.
