. Cattle. Cattle; Cattle. THE TEETH 191 to the four central teeth, in th# manner rejnesented in the cut* The spaces between them will novf evident TWELVE MONTHS. The -ast cut oives the curious and diminutive appearance of all the incisors at fifteen months old. It would appear difficult to ob- tain sufficient food to support good condition. It is somewhat so, and it may be in a great measure owing to these changes in the teeth, and the difficulty of grazing, that young beasts are subject to so many disorders from seven or eight months and upwards, and are so often out of condition. At fifteen months old, the corner teeth will not be more than half their natural size ; the centre ones yet more diminished ; and the spaces between them almost equal to tlie width of the teeth. The faces of the teeth will be lengthened ; the triangular mark will di- minish, principally in the central teeth ; while another more or less deeply shaded, Avill begin to appear around the original maik. All this while the second set of teeth, the permanent ones, have been growing in their sockets, and approaching towards their gums. The piocess of absorption commences in the whole milk tooth, and as much in the crown or body of it as at its root. The process of diminution now is confined to the central teeth, and they gradually waste away until they are no larger than crow-quills. About the end of eighteen months, or a little before, the two central milk teeth are pushed out or give way, and the two C(!ntral permanent teeth appear. The cut gives the mouth at eighteen months old, the two per- manent central incisors are coming up, and the other six milk teeth remain. The bone in front of the lower jaw is taken away, in order.
