chest yielded a dull sound, while auscultation detected an indefin¬ 
able respiratory murmur, a bronchial rattle, and increased expira¬ 
tion. The pulse was proportionately strong, and the internal 
temperature 40.9°. Cent. On a second visit all the symptoms 
were increased, and as they bore a strong resemblance to those of 
contagious pleuro-pneumonia—then prevalent in the district—he 
had the animal slaughtered. On examination only the lungs 
were found to be diseased, being studded with miliary tubercles, 
and as this condition was very unusual, the parts were forwarded 
to Pflug. 
The lungs were fully distended with air, and firm, but elastic; 
for the most part they were anaemic and generally white, only 
small portions being hypersemic. The pleura was normal, but 
there appeared throughout very many miliary tubercles the size 
of a pin’s head, which formed so many slight prominences on the 
membrane, and caused it to feel granular. The lungs did not 
sink in water, even when incised. The cut surface had a fine 
porous, or pumice-stone appearance ; and no serum, but only a 
small quantity of blood could be squeezed from it on pressure. 
The inter-alveolar and interlobular lung tissue appeared to be 
slightly thickened and porous, and this, together .with the emphy¬ 
sematous condition of the alveoli, gave the lung its strongly 
elastic consistency. On the cut surface were seen numberless 
minute tubercles, very granular, in size about that of a millet- 
seed, or a little larger. In the hyperaemic patches the tubercles 
were very conspicuous. In none of these nodules was there a 
yellow centre or softening, and to the unaided eye they looked 
very little different externally, or in consistency, from the ordin¬ 
ary crude grey tubercle which is developed into the yellow tubercle. 
Thousands of these tubercles were observed throughout the 
lung, in the middle of the respiratory tissue, near the bronchi 
and blood-vessels, aud in the vicinity of the lobular tissue. 
On microscopical examinatiou, in the lung substance were 
found an immense number of tubercles, so small that they es¬ 
caped the naked eye. These were generally round, on the cut 
surface discoid, and when two were confluent, biscuit-shaped, or 
distorted, jagged, or gibbous.
