43. _At three years off, the lateral milk teeth are shed, and the permanent teeth are coming up._ The coloured engraving, the original of which is also the property of the Jockey Club, for whom it was executed, was made from the mouth of a bay gelding, by Almack, out of a mare by Rubens, Jun., belonging to--Goring, Esq. The state of the mouth therein exhibited is so peculiar to the age, and so decided in its indications, that it can hardly be mistaken. One of the lateral milk teeth from the lower jaw has been recently lost. The gum is sore, and the top of the permanent incisor is seen rising up. By comparing the temporary incisor, which is speedily to fall from the upper jaw, with those representations of the same teeth given in the previous plates, the gum will be observed to have considerably retracted. Preparation is evidently being made for the change which will in a few weeks take place. The milk teeth begin to be shed about the seventh or eighth month after the completion of the third year, those in the lower jaw being the first to quit the mouth; and all that was observed on the subject in the former paragraph, may be applied to the present, only making allowance for the differences of position in the teeth. 44. _When rising four years old the lateral horse teeth are in the mouth, but their edges do not fairly meet._ The coloured engraving of this age will denote the altered aspect of the mouth, consequent upon the development of a few months, when the colt may want only a dozen weeks for the completion of its fourth year. The original sketch for this plate was taken from the mouth of a horse called the General, the property of Sir Samuel Spry. To test it, however, it has been largely applied, and in every case it has been confirmed. If the mention of names is here required, I may repeat those of Blackbird, Marquiss of Conyngham, and a host of others. The plate, therefore, may be regarded as fully established, and the reader, without fear, may depend upon its correctness. As is shown in the engraving, the lateral incisors, at this age, touch, but nevertheless do not meet so as to be of any service in nipping the food. It is of some importance to attend to this peculiarity, inasmuch as were the presence of the indicative teeth alone remarked, an animal wanting some months to be four years old might be purchased for one that was rising five.
