DISEASES AND RKMEDIKS. 489 



Symptoms. — The following account of this disease ia given by 

 Dr. Brocklesby. For ten days or a fortnight the cattle were 

 troubled with a dry cough, which is indeed not an uncommon 

 symptom among cattle at the close of a severe winter, and there- 

 fore Dr. Brocklesby did not consider it belonging to the present 

 disease ; their eyes looked heavy, and, when the principal disorder 

 appeared, they refused fodder, but had an insatiable thirst for a 

 time. The milk cows decreased in their milk, which remained 

 to a certain quantity, sometimes, for two days, before it changed 

 color, but at length often dried up. On ceasing to chew the cud, 

 a shivering seized them all over, and a high fever immediately 

 came on ; the milk, if any remained at that time, curdled over 

 the fire, but did not in the first of the disorder. At first the 

 belly was costive, but for the most part a looseness succeeded 

 within forty-eight hours after the shivering fit. The stools were 

 first green and watery, and of a stinking smoll; their consist- 

 ence, however, altered afterwards to a viscid, slimy matter; the 

 purging continued till about the seventh day, and about that time 

 the excrements became thicker in such as recovered ; and these 

 soon chewed their cud again, and tasted the fodder, which they 

 had before absolutely refused througii the whole disease. All 

 that had not the looseness before the third day died. The urine 

 was very high colored, and in smaller quantities. The degree of 

 fever was observed very high; upon the third day, the pulse 

 beat nearly a hundred times in a minute, whereas the ingenious 

 Dr. Hales found a sound ox's artery not to exceed thirty-eight 

 pulses in the same time. At different intervals, after the attack, 

 they all labored under a prodigious difficulty, and panting for 

 breath; some suffered these after the first day, others not before 

 the third. But this disorder suffered remissions, and seemed 

 augmented towards evening and at night. Several beasts dis- 

 charged, towards the fourth or fifth day, when ill, a very great 

 quantity of frothy liquor from the mouth and eyes; others ran 

 actually purulent matter from the nostrils. As the disorder 

 advanced, the eyes sunk niore in their orbits, and some were 

 observed to be quite blind. Towards the conclusion, the fore 

 parts of the body, and particularly the glands about the head 

 were prodigiously swelled; and several beasts had a univer.*til 

 emphysema, or crackling of air beneath their skin; those th.it 

 were not blooded equally with such as were. Frequently ono
