290 AMERICAN FARMER'S HORSE BOOK 



given us by Professor Brugnone, of Turin. It commenced 

 with loss of appetite, staring coat, a wild and wandering 

 look, and a staggering from the very commencement. The 

 horse would continually lie down and get up again, as if tor- 

 mented by colic; and he gazed alternately at both flanks. 

 In moments of comparative ease, there were universal twitch- 

 ings of the skin and spasms of the limbs. The temperature 

 of the ears and feet was variable. If there happened to be 

 about the animal any old wound or scar from setoning or 

 firing, it opened afresh and discharged a quantity of thick 

 and black blood. Very shortly afterward the flanks, which 

 were quiet before, began to heave, the nostrils were dilated, 

 the head extended for breath. The horse had, by this time, 

 become so weak that, if he lay or fell down, he could rise no 

 more ; or if he was up, he would stand trembling, stagger- 

 ing, and threatening to fall every moment. The mouth was 

 dry, the tongue white, and the breath fetid ; a discharge of 

 yellow or bloody fetid matter proceeded from the nose, and 

 fetid blood from the anus. The duration of the disease did 

 not usually exceed twelve or twenty-four hours; or, if the 

 animal lingered on, swellings of the head and throat, and 

 sheath and scrotum, followed, and he died exhausted or in 

 convulsions. 



" Black spots of extravasation were found in the cellular 

 membrane, in the tissue of all the membranes, and on the 

 stomach. The mesenteric and lymphatic glands were en- 

 gorged, black, and gangrenous. The membrane of the nose 

 and pharynx was highly injected, the lungs were filled with 

 black and frothy blood, or with black and livid spots. The 

 brain and its meninges were unaltered." 



■ ' DIFFICULTY OF BREATHING. 



Many horses give evidence of. considerable difficulty in 

 breathing, and to such an extent, in many cases, that the an- 

 imal is incapacitated for any thing but the slowest kind of 

 work. Such a condition may result from a partial change 

 in the organization of the substance of the lungs, or from
