several branches at the posterior part of the nose and palate, before they pass to their 

 respective destinations. The lateral nasal nerve, on entering the nose, divides into 

 two portions ; one sends filaments to the concentrated part of the olfactory nerve, as in 

 the horse, and divides into branches, to be distributed on the Schneiderian membrane, 

 covering the turbinated bones, and the rest of the exterior surface of the nose ; the 

 branches pass between this membrane and the periosteum; the other passes to the 

 Schneiderian membrane covering the septum, on which it is chiefly distributed; a 

 branch passes forward, and, at about one-third of the distance from the extremity of 

 the nose, escapes through the palate bone, and is continued on the middle of the 

 palate, to terminate at the anterior extremity of this part. Three bundles of small 

 branches of the palatine nerves pass to the posterior portion of the palate, the- large 

 part of the nerve then passes through the large foramen, and divides into several 

 branches, which proceed to the middle and anterior portions of the palate, and 

 distribute filaments in their course. In the jaguar, a fine branch and a large one, 

 from the second trunk, supply .the teeth of the upper jaw, filaments of both pass 

 through perforations of the bone to the double teeth, the rest of the large branch 

 then supplies the large pointed tooth, passes round the fang of this, and descends to 

 the fang of the first incisor, and winds round this to supply the other two. In the 

 calf, six or seven branches pass very obliquely forwards, so that they ramify on the 

 capsules of the pulps, and enter the teeth at a distance from their origin ; some of 

 them communicate before their termination. After supplying the teeth, the con- 

 tinuation of the trunk, in various animals, emerges beneath the orbit, at one, two, or 

 three foramina, at different distances from the orbit, carefully defended against injury 

 by the prominence of the inferior margin of the orbit, or when it emerges lower down 

 by a ridge of bone ; and although its exit by several foramina is constant in the 

 baboon, it is in some also accidental, and in the calf not unfrequently occupies a single 

 opening on one side, and two on the other ; its usual distribution is, however, nearly 

 the same ; it gives branches to the levator muscle of the upper lip in the calf, but in 

 the pig the branches pass through the fibres of the long muscle of the snout to the 

 skin; it then divides into numerous branches, which communicate generally with
