MR. YOUATT’S VETERINARY LECTURES, 
DELIVERED AT THE UNIVERSITY OF LONDON*. 
Respiration. 
Gentlemen, 
In the partial course of lectures which I had the honour to 
deliver in this University early in the present year, two of the 
systems into which it appeared that our subject might be conve- 
divided were considered—the sensorial and the circu - 
sensorial, the primum mobile of the machines—I spoke 
of the brain —that organ to which all sensation is referred, 
and from which, or from its prolongation in the spinal canal, the 
power of voluntary motion is derived—the fountain of animal 
life,—the medium by which we are rendered conscious of sur¬ 
rounding objects,—susceptible of pleasure and of pain,— and on 
which, through every gradation of being, and those more nume¬ 
rous and extending far lower than many are willing to allow, de¬ 
pend intellectual power and moral feeling. 
I considered that important nerve, the sympathetic or gangli¬ 
onic , whether first brought into view at the base of the atlas, or 
contemplated in those innumerable radiations of nervous influ¬ 
ence concealed in the abdominal cavity, and denominated the se¬ 
milunar ganglion ; one of the fountains of organic life,—ramifying 
over every viscus, surrounding every vessel, and by the influence 
of which the heart beats, and the lungs heave, and the stomach 
digests :—unconnected with sensation but by anastamosis w'ith the 
cerebral nerves, and totally'independent of the will. 
* While there was any doubt concerning the continued delivery of these 
lectures at the University, the publication of them in this periodical was 
suspended ; but a permanent appointment having taken place, there will 
no longer be any interruption in the series.
