    Relics of the pair of plates which fuse to form the vomer in man are to be found in the alee, projecting conspicxiously at the caudal end of the bone. This suggests the probability of the alse of the cat's vomer and of the vomers of other mammals having an origin from paired parts of the developing bone. The dumbbell-shaped bone of Ornithorhynchus is bifid caudally, a condition which seems to follow from the original paired state of this element. It is not, however, my intention at this time to enter into the question of the phylogeny of the vomer. The object of this communication is to record the paired origin of the vomer in a low mammal, in which class generally it must l>e insisted that further study of the development is necessary before the bone can be regarded as azygos in its beginning.
