35 francs. 
The three first plates contain the arteries, veins, and nerves 
of the face and head generally, the region of the parotid gland, 
and the upper part of the throat.- The union of the occipi¬ 
tal, auricular, temporal, parotideal, internal, and submaxillary 
veins to form the jugular is accurately and beautifully deline¬ 
ated. The testes are represented, one enveloped in the tunica 
waginalis, the other displaying thfe contents of the spermatic 
cord. The plate of the nerves and vessels- of the fetlock and 
pastern contains the most satisfactory illustration of the opera¬ 
tion of neurotomy that we have seen. 
The second livraison contains the teeth of the horse—the. 
foot of the ox, viewed anteriorly and laterally—the paunch of 
the sheep—the veins in the face of the sheep—the puncta lacry- 
malia in the horse, the lacrymal sac, and the tendon of the or¬ 
bicular muscle; and the testes of the ram. 'No letter-press is 
yet given, but the plates are beautiful, accurate, and cheap. 
M. Rigot, Anatomical Professor at Alfort, is preparing a se¬ 
ries of lithographical plates, of those parts of the horse which 
are most connected with surgical operations, and of the natural 
size. The first plate will contain the anatomy of the metacar- 
pals and phalanges.
