The Descent of Man

Professor Canestrini, after discussing the foregoing
and various analogous cases, arrives at
the same conclusion as that just given. He adduces
another instance, in the case of the malar
bone (40. 'Annuario della Soc. dei Naturalisti,'
Modena, 1867, p. 83. Prof. Canestrini gives extracts
on this subject from various authorities.
Laurillard remarks, that as he has found a complete
similarity in the form, proportions, and
connection of the two malar bones in several
human subjects and in certain apes, he cannot
consider this disposition of the parts as simply
accidental. Another paper on this same anomaly
has been published by Dr. Saviotti in the
'Gazzetta delle Cliniche,' Turin, 1871, where he
says that traces of the division may be detected
in about two per cent. of adult skulls; he also
remarks that it more frequently occurs in prognathous
skulls, not of the Aryan race, than in

Torino, 1872. Also, E. Morselli, 'Sopra una
