ON COMPARATIVE ANATOMY. 
270 
attention of your readers, more especially veterinary students, to 
the study of minute comparative anatomy; and although their 
thoughts will be chiefly directed to the diseases of the horse, yet 
their skill will be often found useful with other domestic animals, 
as the dog, sheep, &c. &c. It is with regret I have heard 
veterinary students scorn minute dissection, and treat with con¬ 
tempt the anatomy of the dog and other inferior animals. I have also 
heard many argue, that there is no necessity for a minute know¬ 
ledge of the course and distribution of the arteries arid nerves in 
the horse : I contend there is; and when I have perceived the 
slovenly dissections, the ramifications of nerves and blood vessels 
(even where injected) wantonly cut away, I could not help 
experiencing feelings of regret at such conduct. It is neither 
philosophical nor like an anatomist. Your publication appears 
calculated to benefit the public materially; and I take the liberty 
of infonmng you, that I am collecting materials for my large work 
on comparative anatomy, as well as from dissections of my own. 
If any extracts are worth a place in your w^ork, I shall occasionally 
transmit you some. 
I remain, yours faithfully,

ON THE NERVES OF THE UTERUS AND FEMALE 
ORGANS. 
Bj/ C. H. Hawkins, Esq, 
[From the Philosophical Transactions, 1825.] 
^^THE nerves of the human .uterus are supplied from six different 
plexures : the spermatic within the abdomen; the gTeat hypogas¬ 
tric plexus between the common iliac arteries ; and four within the 
pelvis, two of which are situated on each side of the uterus. All 
of these have the peculiar appearance of the sympathetic nerves; 
and they are intimately connected with all the other neiwes of the 
viscera. 
The uterine nerves in the dog, cat, rabbit, and guinea-pig, 
so nearly resemble those of the human subject, as to render a 
minute description of them unnecessaiy. The spennatic plexus 
is formed by branches of the renal plexus and two nearest lumbar 
ganglia of the sympathetic neiTes. It supplies the horns of the 
uterus, the ovaria, and apex of the urinary bladder. 
The common hypogastric plexus, after having supplied the 
• body of the uterus> gives off a large neiTe of considerable length, 
which dips down into the pelvis, and unites with numerous 
branches of the third sacral nerve, and smaller branches from the
