Complete absence of the inferior maxilla is much rarer in man than in animals. Nicolas and Prenant have described a curious case of this anomaly in a sheep. Gurlt has named subjects presenting the total or partial absence of the inferior maxilla, agnathes or hemiagnathes. Simple atrophy of the inferior maxilla has been seen in man as well as in the lower animals, but is much less frequent than atrophy of the superior maxilla. Langenbeck reports the case of a young man who had the inferior maxilla so atrophied that in infancy it was impossible for him to take milk from the breast. He had also almost complete immobility of the jaws. Boullard reports a deformity of the visage, resulting in a deficiency of the condyles of the lower jaw. Maurice made an observation on a vice of conformation of the lower jaw which rendered lactation impossible, probably causing the death of the infant on this account. Tomes gives a description of a lower jaw the development of the left ramus of which had been arrested. Canton mentions arrest of development of the left perpendicular ramus of the lower jaw combined with malformation of the external ear. Exaggerated prominence of the maxillaries is called prognathism; that of the superior maxilla is seen in the North American Indians. Inferior prognathism is observed in man as well as in animals. The bull-dog, for example, displays this, but in this instance the deformity is really superior brachygnathism, the superior maxilla being arrested in development. Congenital absence of the nose is a very rare anomaly. Maisonneuve has seen an example in an individual in which, in place of the nasal appendix, there was a plane surface perforated by two small openings a little less than one mm. in diameter and three mm. apart. Exaggeration in volume of the nose is quite frequent. Ballonius speaks of a nose six times larger than ordinary. Viewing the Roman celebrities, we find that Numa, to whom was given the surname Pompilius, had a nose which measured six inches. Plutarch, Lyourgus, and Solon had a similar enlargement, as had all the kings of Italy except Tarquin the Superb. Early in the last century a man, Thomas Wedders (or Wadhouse), with a nose 7 1/2 inches long, was exhibited throughout Yorkshire. This man expired as he had lived, in a condition of mind best described as the most abject idiocy. The accompanying illustration is taken from a reproduction of an old print and is supposed to be a true likeness of this unfortunate individual. There are curious pathologic formations about the nose which increase its volume so enormously as to interfere with respiration and even with alimentation; but these will be spoken of in another chapter. There have been some celebrities whose noses were undersized. The Duc de Guise, the Dauphin d'Auvergne, and William of Orange, celebrated in the romances of chivalry, had extremely short noses.
