other. From the larger nerves innumerable fibrillse cross in 

 every direction to supply the surrounding muscular fasciculi. 

 Language can convey no adequate idea of the number and 

 plexiform arrangement of these proboscidean nerves ; and, 

 although in this dissection many hundred are brought into 

 view, I have no doubt as many more could be displayed, if 

 suflBcient time could be afforded to the tedious process of ex- 

 posing them. The plexiform arrangement of the seventh and 

 fifth nerves on the human face, though anatomically and phy- 

 siologically analogous to these, yet bears no comparison as to 

 size, number, or complexity. From the intimate union between 

 the seventh, which is the nerve of motion, and the fifth, the 

 nerve of sensation, the greater number of the branches derived 

 from these plexuses must be compound filaments, and, there- 

 fore, supply the parts to which they are distributed with the 

 two endowments, motion and sensation. In this dissection, 

 however, 1 have in several situations unravelled the nerves in 

 the plexus to their respective sources, and traced fine filaments 

 from the fifth or sentient nerve, inwards to the lining mem- 

 brane ; and have also pursued some very large branches of the 

 same nerve, undivided, down to within two or three inches of 

 the proboscis, where they separate into fine hair-like branches, 

 about twenty of which are exposed in one situation, all de- 

 scending in parallel lines to the very border of the opening, 

 where they branch oflF into minute filaments, and terminate in 

 the subcutaneous tissue. 



" 1 shall not delay you with any minute account of the 

 blood-vessels of this organ, and shall only observe, that they are 

 very large and very numerous. Some of the principal trunks 

 accompany the nerves, but many others run in channels 

 through the muscular substance, and distribute their branches 

 to it in every direction. 



" 1 shall next place before you a dissection of the cartilages 

 of the true nose, which are connected above to the nasal bones, 

 and below to the proboscis. These cartilages present a long, 

 curved tube, which is convex forwards, and divided into two
