    description of the anatomy, first of the portio dura, and then of the fifth pair ; and, in accordance with the plan he espouses, omits to take any notice of their distinct roots. “With the view,” he continues, “of contributing some materials to serve as data in an argument of this nature, I shall describe the distribution of the portio dura, and of the second and third divisions of the fifth in the ass, together with the phenomena ensuing on the division of several of their branches, and of that of the frontal nerve. “ The portio dura in the ass passes obliquely outwards and downwards after its exit from the cranium, being covered by the parotid gland, to which it adheres, and reaches the root of the condyloid process of the lower jaw.” And so lie proceeds, describing all its ramifications in the same minute manner. Arriving next at the fifth pair, he enters on its description in this manner :— “ A frontal nerve, from the first division of the fifth, emerges upon the forehead. “ The second division of the fifth, after leaving the skull, crosses the spheno-maxillary fissure, in which it gives off four small branches, distributed to the posterior alveoli, the palate, and membrane of the nose.” The same minute description is continued till he comes to the third division ; and although it is here that the ganglionic and non-ganglionic roots join, he still makes no reference to these parts.
