3. Pedigree showing the Mendelian descent of Eye-colour in mankind.
The Racial Form of Nose and Its Segregative Inheritance.
By Geo. P. Mudge.
The form of a nose doubtless depends upon many factors. But chief among them we may suppose are the length, breadth, and angle of inclination of the nasal bones; the form, length, breadth, and thickness of the nasal septum, and the degree of development of the turbinal bones. The segregation and persistence in families of a definite type of nose-form is a subject well worth further study. The inheritance of this character from the Mendelian standpoint has not yet been adequately studied. But as with eye-colour, so with nose-form, we desire to know not only how alternative characters are inherited among individuals of the same race, but how they are transmitted among the offspring of mixed races.
ENGLISH V. GIPSY.
I am able in the photograph exhibited to show what appears to be an undoubted transmission of a very prominent form of nose from a grandmother to a grandson. The grandmother (on the right of the photograph, who is now over 80 years of age) was the wife of a gipsy and she herself came of gipsy stock. She and her husband eventually settled in a small village in the West of England. They had six children, namely, two sons and four daughters. Of the two sons, one was fair in complexion and had the "wild ways and habits of the gipsy." The other was dark in complexion and married an English countrywoman of the district in which his parents had settled. She was of fair complexion. They are shown, as husband and wife, in the left-hand corner of the central photograph. They have had four children, namely, three girls (shown in the centre of the photograph) and one son (shown standing by the right of his gipsy grandmother in the right corner of the photograph).
