The drawing is taken from a model which Prof. Hochstetter has made from his dis-sections by the plate-method. The model represents the rudimentary brain with its processes, butomitting the ectoderm and mesoderm. The eye rises by a thick hollow pedicle from the lateral wall ofthe first cerebral vesicle, G. At its distal end it presents an indentation, L, which represents theinvagination of the lens vesicle into the ocular vesicle. The limits of the lens ves

The drawing is taken from a model which Prof. Hochstetter has made from his dis-sections by the plate-method. The model represents the rudimentary brain with its processes, butomitting the ectoderm and mesoderm. The eye rises by a thick hollow pedicle from the lateral wall ofthe first cerebral vesicle, G. At its distal end it presents an indentation, L, which represents theinvagination of the lens vesicle into the ocular vesicle. The limits of the lens vesicle are indicated by adotted curved line. From the lower margin of the indentation runs the fetal ocular cleft. This, atfirst very narrow, afterward widens somewhat, and extends down upon the pedicle of the optic vesicle.
