PLATE VI.

[The figures in this Plate were drawn upon the stone from photographs
of plaster oasts of heads in which the brain is exposed in situ. Bars of hone
are left along the lines of the sutures, and, in some cases, also along the fore
part or the whole length of the temporal ridge.]

Figure 6.—Ilead of a female child four years old.

Figure 7.—Head of a male child four years old. (The model from which this
drawing was taken is not very satisfactory, as the brain bulged
somewhat after removal of the cranial wall.)

Figure 8.—Head of a male child rive years old.

Figure 9.—Head of a female child eleven years old.

Figure 10.—Head of a male child twelve and a-half years old.

Figure 11.—Head of a youth fifteen years old.
