TUBERCULOUS DISEASE. 
his reach. Having no hope of recovery^ Mr. Leding- 
ham concurred in my suggestion to have the animal 
slaughtered. This was done by bleeding, in order that a 
careful }iost-mortem examination might be made, a short de¬ 
scription of which will conclude the relation of this case. 
The whole of the digestive organs appeared to be unimpaired 
in structure or function, and likewise those of respiration 
with the exception of the upper end of the trachea, on which 
a gritty tumour had been pressing, thus probably causing the 
occasional cough. On removing the horns a large quantity 
of yellowish fluid escaped; and by laying open the cranial 
cavity and spinal canal from end to end, a very interesting 
scene was presented, which well repaid our investigation. 
The centre of the misehief was the second cervical vertebrae, 
more than two thirds of which had lost all the characteristics 
of healthy bone, and become a gritty, tuberculous mass, 
occupying much more space than is required by the dentata 
in a normal state, to the detriment of adjacent tissues, and 
chiefly the spinal cord. The latter was so eompletely com¬ 
pressed within the mass, that after it was liberated it retained 
its acquired shape as perfectly as if a ligature had still been 
tightly fastened round it. The efiects were, enormous effusion 
of blood under the theca, and over the wdiole brain surface, 
so as to form a complete coating. This extended downwards 
to the mid-eervical region. Along the whole cord posteriorly 
to this, effusion of yellowish fluid was very abundant, escaping 
freely wflien the membranes were aceidentally injured during 
opening up. There was also infiltration of the same fluid 
into the museular tissue in various parts of the body. 
Case 2.—On the 24th of May, 1867, a year-old calf, be¬ 
longing to Charles Wilson, Esq., Hiltown, was observed, 
whilst at grass, to extend her head in a peculiar manner, and 
to have a difficulty in gathering and swallowing her food. I 
was called immediatelv, and had the animal housed for in- 
speetioii. Ko foreign body was lodged in the mouth or fauces. 
Manipulation of the trachea evinced tenderness, but auscul¬ 
tation indicated no thoracic disease. Considerable depression 
was manifest, but nothing pointing to a fatal result. 1 treated 
the case as one of inflammation of the mucous membrane of 
the larynx and traehea by blistering in that region, and 
ordering laxatives and linseed gruel. 
On the 29th I found my patient standing obstinately in a 
corner, and much averse to having her head moved. There 
was some efiusion at the brisket, resulting from the blister, 
and the cough had ceased. The appetite was entire lost, and 
greatly increased depression of the vital powers was apparent.
