line, as if they were leagued in the performance of the same 
office. 
They are the portio dura of the seventh pair, distributed over 
the face; the glosso-pharyngeus, which supplies the pharvnx 
and the tongue; the par vagurn, wandering to the pharynx, the 
larynx, the heart, the lungs, and the stomach ; the recurrent, 
ramifying on the muscles of the larynx, and the membrane of 
the glottis; and the spinal-accessory given to the neck and 
shoulder, and reaching even to the loins. 
• The twdtchings and contraction of the eyelids, the strabismus, 
the spasms of the cheek, and lips, and face, and the paralysis 
of the muscles of the lower jaw, sufficiently prove an affection 
of the portio dura. 
The protrusion of the tongue, the enlargement of the sublin¬ 
gual and other glands, the inability to swallow, and the altera¬ 
tion of the voice, implicate the glosso-pharyngeus. 
* The increased circulation, the laborious respiration, the pe¬ 
culiar inflammation of the pleura, and the constant and often 
intense inflammation of the stomach, are attributable to the 
par vagum. 
‘ The involuntary barking, the husky grating inspiration, the 
frequent inflammation of the trachea, the uniform inflammation ' 
of some part of the glottis in the quadruped; and the dreadful 
excitation of the membrane of the glottis, wdth all the horrors of 
hydrophobia in the human being, testify that the recurrent nerve 
has not escaped : while the hurried and uncertain action of the 
fore extremities, and the palsy of the region of the loins, are 
clearly to be traced to the spinal-accessory. 
These nerves anastamose freely with the cerebral nerves, 
therefore cerebral affection soon occurs. There is a state of 
•general and extreme excitation, a very peculiar w^andering and 
delirium, and, in some animals, fits of savage and uncontrolable 
ferocity. 
They likewise unite and blend with the ganglionic nerves, 
and thence proceeds altered secretion—a morbid secretion of the 
gastric juice occasioning the strangely perverted appetite of the 
dbg; and a still more depraved secretion of the saliva, convert¬ 
ing that bland and innocuous fluid into the direst poison. 
Dr. Parry approached the subject, when he asserted that it 
was principally an affection of the organs of respiration*. The 
* Let his uncandid review, and gross mis-statement of some cases pub¬ 
lished by me 15 years ago, be now forgotten. The wound rankled for a 
while, and the more so, as inflicted by the friend and fellow-student of my 
father. He now sleeps in peace. He. was a scientific practitioner, and a 
good man.
