In this case the chiasma is so slender that it seemsimprobable that either laryngeal nerve should exercise as much influence onthe opposite as on the same side with itself. In the Alligator.—As in the preceding, the dissection was made on a de-tached larynx. The chiasma is relatively larger than in either of the other instances; is of the same size as thetrunks which contribute to the formation ofit, and is protected by a very thick sheath ofwhite fibrous tissue; in addition to branchesof nerves distributed to the muscles as in thepython and the birds, two others are givenoff near the median line, which perforate thewalls of the larynx and are distributed to themucous membr
