GROWTH OF SKULL.
MODELS ILLUSTRATING DEvEL-

Preparation an Extensive Col

questions that may be more easily an.

a new collection of skull models. The
work OF making a model collection
which will show the development o.
skulls from the lowest forms to tn
highest has been in progress for the
last Is months. says the New York
Tribune. The reptiles have just been
reached in the ascending scale OF

One might ask why the skull wa

The answer for one thing Is that
