Mr. Sliaw on the Facial Nei-ves. 233 



cated in the monkey than in the dog, its intricacy being ap- 

 parently in proportion to the number of the muscles of expres- 

 sion. From the lion, the dog, and cat, we descend to the horse, 

 ass, and cow ; in these animals, there is a marked difference in 

 the distribution of the nerve, from that of either the monkey or 

 the dog, for, excepting a few branches, which pass to the muscles 

 of the external ear, and to the eyelid, the whole of the respira- 

 tory nerve is confined to the muscles of the nostrils and side of 

 the mouth, while in the carnivorous tribes it is spread in great 

 profusion overthe cheeks and side of the neck. 



There are, however, some varieties in the classes of grami- 

 nivorous animals. In the gazelle, sheep, and deer, the distri- 

 bution of the nerve is still more simple than in the horse ; 

 while in the camel it is more profuse, and is, in this respect, 

 intermediate between that of the carnivorous and the gra- 

 minivorous animals. The expression of the enraged camel 

 is sufficiently ferocious, and the manner in which he shews 

 his tusks, when dying, is very similar to that of a carnivorous 

 creature*. 



We are told by those who have seen an elephant in a rage, 

 that he is most sublime and terrific; but the anatomy of the

 from that of the greater number of quadrupeds. 



We had an excellent opportunity of examining it last spring, in the 

 courier caraci, or maherry, which was brought from the interior of Africa, 

 by Captain Lyon, as a present to his Majesty. In the dissection of this' 

 animal wc noticed many interesting facts, which have been overlooked 

 by co„.parativc anatomists, and |)articularly the difference of the distri- 

 bution of the nerves of the neck and stomach, from that of the same 

 nerve in the horse and ass, and from that in the greater number of rumi- 

 nating animals. 



We found that the nerves of the neck, in their number and distribution 

 resembled those of a large bir.1, as the swan, &c.. much more than those 

 of a horse or bullock, and particularly in the spinal accessory, or superior 

 rubpiraloryof the trunk, being either deficient altogether, as in birtis or 

 quite different to what it is in the greater number of quadrupeds. This 

 anatomical fact is a strong proof of Mr. Hell being correct in the opinion 

 Hhich he has formc.d of the use of this nerve. While in Paris lust Sep-
