The nostrils are bulged inwards, and more or less obstructed; but, in the later stages at all events, there is no discharge, neither can any breach of the mucous surface be detected.

I would point out, however, that the symmetry of the growths is difficult to account for on this hypothesis. Maclaud observed a similar affection in a chimpanzee.
Strachan records and illustrates an instance of goundou in a West Indian negro child. (Fig. 223.) In this case the swellings were congenital, and had only increased in proportion to the child's growth. They were hard, smooth, bony masses, somewhat of the shape and size of an elongated pigeon's egg, and sprang from the nasal process of the superior
