qualit}^, will, in many cases of depression, not only cure the dis- 

 ease, but remove the cause also. 



Fever. 



There are four stages observed in fever :— 



(1.) Weakness, loss of appetite, and low spirits. 



(2.) A shiver, or chill, uneasiness, flanks move quick, and short, 

 nostrils more or less distended, one leg or ear hot, and the other 

 cold. 



(3.) After a time the coldness is succeeded by great heat and 

 thirst, costiveness, urine scanty and high-colored, mouth hot and 

 dry. 



(4.) When the fever has lasted for a longer or shorter time, 

 the skin becomes more moist, the bowels and kidne3's act more 

 freely; the pulse becomes more full, although not less frequent, 

 and the mouth more moist. 



When fever is accompanied with disease of the lungs, liver, or 

 other organ of the body, or after an accident of any severity, it is 

 then called sympto^natic fever. 



Fever is called idiopathic, when not accompanied by disease or 

 accident. From the days of Galen to the present time, of the 

 many tlieories advanced to explain its proximate cause, none seem 

 to satisfy the philosophical student, and all belong to the unsolved 

 problems in physiology. 



Diseased Secretion. — A good example of what is here meant ma}^ 

 be found in the discharges from the nose of animals affected with 

 cold, influenza, and glanders. The salivary gland may secrete too 

 much fluid, as horses eating second crop clover. We call this 

 salivation. 



Increased Secretion. — In health, serum is only supplied in suffi- 

 cient quantity to keep the surfaces moist, the absorbent vessels 

 ])reventing accumulations. In the cavities of joints this secretion 

 is often too large, causing enlargements, of which a very good ex- 

 ample may be seen in swellings of the hock-joint, called bog 

 spavin, and also in thorough-pin. 



The Pulse. 



The pulse of the horse and the ox is felt on the inner angle of
