The annexed diagram, (fig. 405.) with the letters attached to it, will assist the reader in following this otherwise intricate description. It is taken from a drawing by Morganti in the essay referred to; but it has been reduced in size and simplified, so as better to allow of its introduction here. The same author has examined into the comparative anatomy of the ganglion and the nerves connected with it in many of the other mammalia, as the dog, calf, lamb, mule, and dormouse. The general results of these examinations abundantly verify his description of the ar- rangement in the human subject. Indeed, these animals offer by far the most favourable subjects for exemplifying the truth of the preceding description, being, as Morganti remarks, natural preparations of these parts. Not only is the dense and intimately adherent sheath of fibrous tissue, which is present in man, much looser in the ganglion anil nerves of these animals, but the position of this body with respect to the nerve is considerably altered. The much less marked anterior bend of their portio dura occurs at some little distance from the hiatus Fallopii ; and the ganglion, which is in immediate proximity to this aperture, is thus no longer gcniculate in its position, being removed from the knee o
