REPORTS OF CASES. 
Treatment .—Gave magnesium sulphate 500.; aqua, litre, 
and left fluid extracts of nux vomica and gentian to be given 
every three hours, and told owner I would call next day. 
January 24. Owner sent me word not to call as cow was all 
right. 
Jan. 28. Was called to see same cow and found her refusing 
both food and water; temperature 105° F., pulse 132, heart 
pounding and thrilling, eyes unnaturally bright, jugulars tense 
with blood but no jugular pulse ; left lung tympanitic on per¬ 
cussion, submaxillary space cedematous, anterior limbs projected 
alternately. 
Revised Diagnosis .—Traumatic pericarditis. Prognosis un¬ 
favorable and advised destruction and use of meat, but the owner 
was skeptical as to correctness of diagnosis and wished to con¬ 
tinue treatment, hence gave fluid extract of digitalis 4., ter in 
die , more expectant than with any hope of ultimate benefit. 
Jan. 29. No apparent change ; treatment continued. 
Jan. 30. Owner decided to destroy the cow, and post-mor¬ 
tem was performed immediately. 
Post-moi r tem .—Gydema of the subcutaneous tissue on both 
sides of the thorax with a yellow gelatinous semi-fluid substance 
in abundance. Reticulum adherent to the tendinous portion 
of the diaphragm and pierced with four pieces of hay wire about 
eight centimeters long, one of which had completely pierced the 
wall of the heart and protruded into the left ventricle. 
On the end of the wire which protruded into the heart was a 
small ante-mortem clot. Pericardium was adherent over nearly 
the whole heart and when pulled apart seemed dovetailed or 
something like a foetal and maternal cotyledon. 
The other organs were normal. 
HYPO-SULPH. SODA POISONING. * 
By Dr. J. G. Parstow, Shenandoah, Iowa. 
On March 19th I was called to Red Oak, Iowa, to investi¬ 
gate a trouble existing in a large barn of feeding horses. On 
my arrival I learned two had already died and was shown four 
or five that were quite sick. The symptoms, as the owner and 
caretaker had noticed, were loss of appetite, whisking of tail, 
followed by light colicky pains and profuse diarrhoea, the colicky 
pains gradually increasing in severity until extreme agony was 
evinced in those two that had died.
