    bones articulate with each other in the median line, the upper portion of the roof of the nasal f ossse is thus complete. The superior ends of the nasal bones articu- late with that portion of the lower border of the frontal bone lying between the nasal processes of the superior maxilla. These bones thus uniting form a very resist- ing roof, narrow and very thick above wdiere it articu- lates with the frontal bone, but in descending it spreads out, becomes much thinner and terminates in a very sharp border to which is united the lateral nasal carti- lages. Thus this firm and unyielding portion of the roof securely protects the olfactory region from any external violence. The Cartilaginous Portion.—This portion of the nose consists of four large and distinct cartilages, sit- uated two on either side of the median line, united to- gether by strong fibrous tissue, and of several small floating cartilages, which vary in number and form. Of the four larger cartilages, which, as already stated, are divided into pairs, situated two on either side of the median line, the upper two are known as the lat- eral nasal cartilages ; and the lower pair, together with the floating cartilages, are called the cartilages of the aloe. The Lateral Nasal Cartilages.—These triangu- lar cartilages are situated below the inferior border of the nasal bones, and are united to them by a firm fi- brous union. Besides being joined to the nasal bones, they are united to the anterior margin of the septum and also to the nasal process of the superior maxilla. While their external surface is convex their internal surface is concave, this concavity forming a part of the superior portion of the nasal fossae. Externally these two cartilages are covered by the borders of the pyramidalis nasi, and the compressor nasi muscles ;
