THE DISEASES OF CATTLE. 307 



PEMPHIGUS, OR VESICULAR ERUPTION. 



In the United States, at least in this region, pemphigus is of 

 rare occurrence, yet it has made its appearance in Texas and 

 in the Western States. The following symptoms, which usu- 

 ally accompany this eruptive affection, may enable the reader 

 to recognize it. 



Symptoms. — The breathing is generally hurried and sono- 

 rous, accompanied by a slight cough ; the animal shivers, which 

 is occasioned by deranged and irregular nervous action. The 

 integument in the regions of the neck, shoulders, anus, loins, 

 and haunches, is elevated by effusion into the cellular tissue ; 

 the cuticle, or external tunic of the body, is the seat of watery 

 bladders, varying in size from a Beverly bean to a walnut. In 

 other parts of the skin a serous or watery fluid may be ob- 

 served to dribble from the hair. The ears are drooping and 

 moist, and their temperature is much elevated. The base of 

 the horns are hot, and the whole external surface of the body 

 is in the same condition. The visible surfaces, viz., those of 

 the eyes, mouth, and nose, are highly injected with a reddened 

 yellow tinge ; the tongue is swollen or tumefied, and an abun- 

 dance of saliva flows from the mouth ; the pulse will often run 

 up to 80, yet may be imperceptible at the jaw. The spinal 

 column presents a convexity, or is arched upwards. The urine 

 is scanty and dark colored, and the faeces are of a lighter color 

 than usual, showing very conclusively that the function of the 

 liver is impaired. 



As the disease advances, the serous tumors burst, exposing 

 broad excoriated patches. 



Treatment. — Let a portion of the following mixture be ap- 

 plied to the surface of the body, by means of a sponge : — 



Glycerine, 4 ounces. 



Sublimated Sulphur, .1 ounce. 



Lime \Y*t®i^> 8 ounces. 



Linseed Oil,. 2 ounces. 



Two or three applications of a portion of the above, on suc- 

 cessive days, will soon change the morbid habit of the skin, 

 when the residuum may be removed by sponging the surface
