As in other Vertebrates,it has the longest course, widest distribution, and most numerousconnections, of any of the cerebral nerves; but is noted, in Mam-mals, by receiving the accessory nerve, ib. 5,11,12, from a greaterextent of the myelon : the recurrent branches of the vagus aremore exclusively distributed to the trachea and larynx, and senda smaller supply of nerves to the oesophagus than in Birds orReptiles. From the remarkable length of the neck of the Giraffe, thecondition of the recurrent nerves attracted my attention in dis-secting that animal: they were readily distinguishable at theupper third of the trachea, but when sought for at their usualorigin, this was less obvious.
