Fig. 6. Vertical Section through Head of Foetal Pig, 4 mm long

Magnified about 1,000 times.

Til a vesicle is formed which is known as the lens vesicle, as shown at A, Fig. 6. Then this vesicle hecomes separated from the surface and passes into the secondary optic vesicle (see A, Fig. 7), and eventually forms the lens, which will be described later.

As the lens vesicle passes into the secondary optic vesicle, some of the mesoblastic cells pass upward from below, behind it (see B, Fig. 6), and it is these mesoblastic cells which will eventually multiply and form the vitreous body. It will be remembered that the mesoblast is the middle layer of the three primary layers, first formed in the foetus.
