Contagious Disease among Cattle in Mecklenburg. 33^ 



ment, and adhering to bones ; ears and horns febrile, with alter- 

 nations of great heat and cold ; respiration accelerated, but deep, 

 with visible motions of nostrils ; cough more frequent, violent, 

 and ringing ; pulse hard, from seventy to seventy-five pulsations 

 per minute ; appetite entirely gone, though some cattle, in this 

 stage of the disease, take their food as usual ; most of them are, 

 however, unquiet, toss up their heads, shiver, and gnash their 

 teeth ; if stroked on the back, they bend down and low mournfully, 

 seldom lie down, and, when they do so, instantly get up again ; 

 void excrements frequently, urine seldom ; in voiding excrements, 

 back much bent, tail turned high up, animal turning its head 

 towards the rump and striving to lick it ; excrements dark- 

 coloured, hard, dry, ustulatious pellets ; urine red and clear ; 

 fever intenser in the evening than in the morning, and, as it 

 increases, animal shakes its head, shivers, gnashes its teeth, and 

 refuses to take food. Cows give but little milk, which is, how- 

 ever, more creamy than usual. 



Ninth and tenth day : fever becomes putrescent, small white 

 pustules break out in the mouth, which, when they burst, leave 

 dark red spots that easily bleed ; similar pustules appear in the 

 nostrils and between the clefts of the hoofs ; hide in some places 

 intumescent; eyes dim, eyelids hanging down; from the eyes 

 flows a pituitous lachrymose humour, which dries up at the edge 

 of the nostrils ; nostrils exude a dingy-white viscous humour ; 

 tongue shrivelled, and often hanging loose out of the mouth, 

 covered with an impure saliva; teeth loose; mucous membrane 

 of mouth sebaceous, and falling off in large pieces ; breath putrid 

 and nauseous ; muzzle hard and cracked, like the bark of a tree ; 

 hair rough and without the least gloss ; parchment-like hide, now 

 covered in some places with nodules, on which appear small 

 pustules contiiining a yellowish humour ; pustules burst, humour 

 dries up, and a mangy eruption ensues, commonly on the back, 

 anus, and udder ; rumination ceases ; animal reduced to a skele- 

 ton ; pulsation 80 to 100 per minute; respiration quick, wailing, 

 and painful ; alternations of heat and cold ; on tlie side of the 

 more diseased lung heat greater and of longer duration ; excre- 

 ments, previously liard, are now soft, loose, and watery. This 

 state is followed by choleraic diarrhcra, with acrid, purulent, 

 brownish, or Ijlackish green faeces, smelling like carrion. If con- 

 stipation now ensues, the animal swells up and soon dies. If, 

 instead of diarrlura, a more natural evacuation of the howels takes 

 place; if the animal warmth i)econu's more normal, rcspiraticui 

 more free, pulse slower and fuller; if the hide scales off, and 

 regularly running sores (abscesses) are formed, recovery may be 

 expected. This is, however, very seldom the case, the above- 

 mentioned symptoms generally increasing after a short illusorv
