last two kinds are called bastard or unusual strangles. It is often fatal^ 

 but such cases are duo to neglect, to colds from exposure while the fever 

 is high, etc. 



Causes. — It often arises spontaneously, from the existence m the sys- 

 tem of some morljific matter developed while growing ; for spontaneous 

 cases are only found among young horses ; when older ones have it, it 

 comes from contagion. 



How to know it.— There are all the indications of fever — quick, weak 

 pulse ; high temperature ; hot mouth ; cold extremities ; staring coat ; 

 loss of appetite, and nervous prostration. In a few 

 hours the throat begins to swell, both on the sides and 

 between the branches of the lower jaw ; this swelling 

 is sometimes immense, and makes the colt hold his 

 neck and head stretched out in one position, stiff, 

 like a child with the mumps. There is usually a 

 distressing cough and inability to swallow ; often 

 there is a desire to eat, but the throat is so sore he 

 cannot swallow. The nose runs a mucous discharge 

 at first, which soon becomes purulent ; the eyes very 

 red, and tears run down over the cheeks. The swel- 

 ling is painful and sore upon pressure, and usually 

 A BAD CASE OF brcaks in about a week, and discharges pus. When 

 these swellings come in the lungs, the breathing will 

 be affected, and the chest will be sore upon pressure or percussion on the 

 ribs, and he will stand all the time. If it comes in the abdomen, colicky 

 pains are felt, and he lies down nearly all the time. Sometimes it comes 

 around the heart. Any of these unusual forms are likely to be fatal. 



What to do- — Avoid depletives of all kinds, and foster the strength of 

 the patient in every possible way. If the bowels are constipated, give a 

 few injections, Init do not risk a purgative ; give recipe No. 40 every two 

 to six hours with a syringe, for it is unsafe as well as painful, to try to 

 drench him with the throat in that condition. Apply hot linseed poultices' 

 to the swellings, and let them get very thin indeed before opening them ; 

 or, even let them burst of themselves to avoid that thickening often seen 

 after being opened. It is no use trying to check it ; it must run its course. 

 Give him a warm, dry place, well ventilated, and nourishing food such as 

 boiled oats, barley, roots, etc. During convalescence give recipe No. 35. 



III. Rabies or Hydrophobia. 



This is a specific blood poison, arising spontaneously in the genus
