![their number, origin, course, connexion, &c., of which we shall here notice the most important. The total want of nerves never seems to occur in monsters, however imperfect they may be, as the organs which are formed always possess some nerves.^ Frequently, however, is there a want of single or several NERVES, as, not merely in monsters of which certain parts are deficient, the nerves which are naturally appropriated to or are connected with them are totally or partially missed,^ but even in those which are present and are imperfectly formed, as iii deficiency of the mass of muscles of the limbs, the nerves are deficient.* Most frequently are the anterior nerves of the BRAIN deficient, and principally indeed in those monsters with imperfect formation of the nose, the eyes, and the face; ^ we also see, especially in such monsters, the olfactory nerves deficient;*^ this, however, occurs also, in rare instances, in other- wise well-formed persons.^ The optic nerves stand also in a similar relation to the eyes, so that when these are entirely deficient, both optic nerves are also absent; ^ but if the eye on one side only be wanting, the nerve on that side is alone defi- cient,^ and also in cyclopic malformations, according as the consolidation of both eye-balls varies, so does that of the optic nerves into one.^ Vices of the third, fourth, and sixth PAIRS OF NERVES, as wcll also as the first branch of the fifth pair, are also usually connected with the total want or the deformity of the eyes.^^ In one cyclopic monster with nearly total absence of the face, the facial nerve did not exist.^- In very imperfect organs of hearing, the auditory nerve has been missed.^^ Where the tongue has been defi- cient, there has been noticed not merely deficiency of the lingual branch of the fifth pair of nerves, but also of the MUSCULAR lingual nerve.^* The opposite vice or excess OF number of the nerves, occurs, when we notice, as is proper, the uncommon and too early division of a nerve into its branches, not, however, but with excess of the parts with which it is connected,*^ and this is then generally to a certain extent dependent on their form; thus, for instance, with a supernu- merary vertebra we have a spinal nerve too many; a sixth finger, which is perfectly organized, has also an uncommon digital nerve, &c.; in double monsters, of which the head, belly, or limbs, are simultaneously consolidated of two, we find in their parts, according as they diiier in the greater or less degree of their consolidation, the nerves either completely double or divided, or double and anastomosing at certain ]><>ints, or lastly, double at their origin, but jiassing singly I'rom their junction.'
