42 LIST OF SPECIFICS AND REMEDIES. 



more difficult ; the breath is very hot ; the eyes 

 and nose ar lead colored ; the skin is cold, and 

 clammy sweat breaks out upon it here and there ; 

 the mouth is cold ; the tongue is coated ; the teeth 

 are ground every now and then, and twitches are 

 occasionally seen. The eyes become more and 

 more heavy, glassy and dim ; the strength be- 

 comes less and less ; the horse leans against the 

 stall or manger, or wanders around ; he staggers 

 and falls ; tries to rise, but can not : groans, strug- 

 gles and dies. 



As an improvement takes place, the horse ap- 

 pears more natural, warmth returns to his ex- 

 tremities, his breathing is more free, pulse softer, 

 fuller and less frequent, cough easier, and he lies 

 down quietly, and without uneasiness. These 

 good symptoms rarely or never deceive. 



Placing the ear against the ribs, upon various 

 parts of the chest, we may learn with some prac- 

 tice to distinguish the progress of inflammation. 

 In the healthy lung, the air passes in with a 

 slight rustling murmur, quite characteristic, and 

 which, once heard, will always be recognized. As 

 the lungs become inflamed, "crepitation" takes 

 place, and we hear a sound, slightly crackling, 

 like that made by salt thrown into the fire, or by 

 rubbing the hair between the fingers close to the 

 ear. As, by degrees, the lungs become more in- 

 tensely inflamed, it is more and more impervious 

 to the* air, until it becomes " hepatized " or solid, 

 and makes no sound, and no resonance when pre- 

 cussed or struck upon These changes are inter- 

 esting, and afford to the practiced ear clear indica- 

 tions of the state and progress of the disease. 



PROGNOSIS. Horses may get well in all stages 

 of Pleuro-Pneumonia, except in very extensive 

 hepatization, when, if recovery occurs at all, it
