    THE RELATION OF THE ALVEOLAR FORM OF CLEFT PALATE TO THE INCISOR TEETH AND THE INTERMAXILLARY BONES. By Professor W. Turner, M.B., F.R.S. (Commuaicated to the Royal Society of E Unburgli, Dacaraber 15, 1884.) In aQ essay on the iiitermaxillary bone published in 1786, the illustrious Goethe, by the recognition of a suture on the palatal aspect of the upper jaw, extending from the incisive foramen to the interval between the canine and lateral incisor tooth, and of a prolongation of the same suture into the naso-palatine canal, determined the presence of this bone on each side of the human upper jaw. In a subsequent essay, published in 1819, he cited other facts in support of this position, and stated that in hare-lip the incisive or intermaxillary bone is separated from the superior maxilla, and the suture between the two bones remains open. Since that time it has been the current doctrine that the lateral cleft in the alveolar border of the jaw, which so frequently accompanies a hare-lip, marks the separation between the inter- maxillary and superior maxillary elements of the human upper jaw. In an essay published in 1879,^ Dr Paul Albrecht traversed this conclusion of Goethe's. From the examination of the skull of a young horse, with a double hare-lip and alveolar cleft, of the skulls of two calves with lateral alveolar clefts, and of similar malformations in the human upper jaw, he came to the conclusion that the cleft was not between the intermaxilla and superior maxilla, but was intra-incisive in position, and co- existed with the usual suture of articulation between the supe- rior maxilla (exognathion) and the intermaxilla. He considered that the explanation of this condition was to be looked for in the presence during earlier stages of development of two inter- maxillary bones on each side, a mesial (endognathion) and a 1 Die morphologische Bedeutung der seitlichen Kieferspalte and die wahr- scheinliche Existenz von vier Zwischenkiefern bei der Saugethieren, Zoologischer Anzeiger, 1879, p. 207.
