![lowing is what we frequently observe: (i) A nar- row nose with weak, flaccid alae. (2) Thickening of the septal base in its anterior part. (3) A great redundancy of the soft parts below and anterior to the cartilage. (4) The floor of the nostril just be- yond the entrance is sometimes observed to rise from to 1/6 of the total distance to the apex of the opening, thus forming an obstructive ridge at a right angle to the meatus. Thus from the inner and outer sides and from the floor the lumen of the nostril may be encroached upon. In the above de- formities prenatal conditions combine with defec- tive nasal breathing during the growing period to produce the picture. (5) The traumatic nose with broken down, piled up cartilage and distorted, irreg- ular anterior floor. 'Fhe better to understand what follows. I shall give you a brief description of the anatomy bear- ing upon this operation. In the desiccated skull the nasal openings resemble an ace of hearts in- verted. With the lower boundary of this opening we are concerned. You will observe that it ])resents a sickle-shaped edge, more or less sharp and more or less raised above the floor of the nasal passage behind. If the floor level behind be carried for- ward we find that this edge in many skulls is from to 2/3 cm. above it. Now if we examine a nos- tril infra vitarn we shall observe that this edge lies about T cm. behind the junction of the upper li]) and nasal opening, and that the direction of this portion of the nostril floor inclines upward to meet at the apex of the ridge the upward inclined plane of the meatel floor behind (Fig. i). This crescentic ridge then forms the highest ]:>ortion of the floor, which might be represented thus](https://iiif.wellcomecollection.org/image/b22480705_0006.jp2/full/800%2C/0/default.jpg)
