PARALYSIS IN AN OX. 
and the brain being divided. The respiration would have ceased 
unless it had been kept up by an intense act of volition. Sir Benj. 
Brodie had no doubt that contractile power was possessed by the 
lungs, and assisted to some extent the muscles of respiration. A 
French physiologist had remarked, that in wounds of the chest the 
lungs protruded. Sir Benj. had also found this to be the case. 
During inspiration, the protruded lung returned into the cavity of 
the chest, but again protruded in expiration, shewing that the chest 
(lungs'?) had a contractile power independent of the muscles. 
Dr. Budd believed that in the case of hydrophobia related by the 
President, the bladders of air found in the lungs after death were 
collections of air which had extravasated into the cellular mem¬ 
brane. Such extravasations were altogether different from that 
dilatation of the air-cells which constituted emphysema, and was 
not uncommon in cases of croup and hooping-cough. In the cases 
of spasmodic asthma, he contended that the spasm did not exist in 
the bronchial tubes, but in the internal muscles of respiration. 
There was certainly some appearance of muscular fibres in the 
trachea when viewed superficially; but seen through the microscope 
this would be found not to be the case. He had made manv care- 
ful examinations and experiments to determine this question. An 
ox was killed with the blow of a pole-axe : the trachea was imme¬ 
diately removed, and the anterior rings divided. No contraction 
succeeded to the application of the galvanic fluid. 
Mr. Macilwain believed that the idea that asthma was dependent 
upon dilatation was erroneous. He considered that the disease 
was the result of extravasation of air into the cellular tissue, by 
which the capacity of the air-cells became diminished. 
Dr. Jno. Wilson related two cases in which the patients pe¬ 
rished from emphysema of the lungs, both cases after death exhi¬ 
biting precisely the same morbid appearances. In on^ case the 
sound on percussion was preternaturally clear, but not so in the 
other : he could not account for this difference.

The patient was an ox between fourteen and fifteen years old,
