OBSERVATIONS TO ASSIST THE DIAGNOSIS OF TRAUMATIC PERICAR¬ 
DITIS OF BOVINES. 
BY M. BONNIGAL. 
1st case.—A cow, four years old, was sick for three weeks; was 
treated successively for indigestion, enteritis and then general an¬ 
aemia. In her history it was stated that she had first been tym¬ 
panitic, had lost her appetite, then lost her milk, and was becom¬ 
ing very weak. She had two large swellings, one at the dewlap 
and the other at the base of the tongue. When seen, the general 
symptoms excluded abdominal troubles. The swelling and condi¬ 
tion of the circulation indicated trouble in that apparatus. The 
swellings were neither warm nor painful; the venous pulse was 
well marked at the dilated jugulars. Percussion revealed nothing 
in the thorax, but auscultation showed absence of normal sounds 
and singular actions of the heart. When the animal was exercis¬ 
ed for a minute only, dyspnoea was threatening and the frequency 
of the beatings of the heart increased. It was a pericarditis, which 
was believed to be traumatic, in taking into consideration the symp¬ 
toms of the animal when first taken sick. A needle was said to be 
the cause of it. The animal was destroyed, and at the post mor¬ 
tem a fistulous tract, running from the rumen to the right auricle 
was found, with a large needle in it. The pericardium was strong¬ 
ly indurated on its two coats. Its cavity and the size of the heart 
were double their normal conditions. The sac was filled with 
yellow, thick, purulent fluid. 
2nd case.—This case has about the same history ; considera¬ 
ble swelling on the dewlap; the jugulars dilated; venous pulse 
well marked ; no dyspnoea after exercise. Percussion, negative; 
auscultation revealed the beatings of the heart to be very weak, 
rapid and irregular. Same diagnosis is made and at the post 
mortem a knitting needle was found floating in the cavity of the
