By that time Mr. Chase had recovered sufficiently from his ossification to speak.
At the age of three, the ossification of the cranial vault has been completed.
The ossification of the sacrum also has reached its culminating point.
The ossification of each fragment appears to have been complete.
This ossification is evidently that shown in Notobatrachus as "coracoid."
Tertiary centers of ossification are in the lateral processes.
On the other hand, the cartilage may undergo calcification or ossification.
As to the processes which take place in the ossification of cartilage there is still much to be made out.
The first vertebra to ossify is the second or third cervical, and the ossification gradually extends to those behind.
On the twelfth day the ossification of the cartilaginous centra commences.
