EXTRACTS FROM FOREIGN JOURNALS.

then in season, and he fell a victim to what his master de¬ 
scribed as a severe cold, and continued to cough and expec¬ 
torate for about one month, when the cough ceased. At 
this time the dog was in poor condition, with an appetite 
either lacking or perverted into a morbid craving for putrid 
material. He also suffered from continual thirst, and showed 
signs of exhaustion after the least exertion. 
The symptoms present were a slow and painful walk; a 
pulse accelerated and occasionally thrilling, and a hurried 
respiration. Pain was manifested by a complaining whine 
when the animal was raised from the ground. Percussion 
betrayed dullness on both sides of the chest up to the angles 
of the ribs, and above this the sound was tympanitic. Hyper¬ 
resonance was especially marked at the posterior upper third 
on the left side. On auscultation the friction sound was still 
present in the upper part of the chest, but there only. In the 
lower part, the vesicular murmur was absent, except when 
the patient was placed on his back. The same result could 
be brought about anteriorly and posteriorly by elevating 
either the fore or hind quarters. The heart sounds were re¬ 
placed by one of a booming character on both sides at the 
upper part of the chest. Hydrothorax was diagnosed, and 
thoracenthesis performed, a considerable amount of fluid es¬ 
caping, and two minutes afterward the dog died. 
At the post-mortem a pint of fluid was found in the chest; 
the lungs were adherent to the thoracic walls ; a few yellow 
spots were found on the pulmonary pleura; the left lung 
was converted into an inflated cavity, the walls of which were 
composed of shrunken lung tissue, adherent to the chest 
wall at the upper posterior part. The cavity contained a 
quantity of caseous material, which on straining showed 
numerous tuberculous bacilli. The heart was hypertrophied, 
the pericardium thickened, and the liver was full of blood, 
the other organs being normal .—Journal of Comp . Path. &
