to expand in the left hemisphere of the cerebrum. We see the quadrigemina on the back of the ascending fibres and their connection by fibres with the cerebellum behind, as they connect with the thalami in front.

 

This is as complete a statement of the structure of the brain as is necessary, and further anatomical details would only embarrass the memory. [Illustration] The engraving above represents not an actual dissection, but the plan of the fibres as understood by the anatomist. The intricacy of the cerebral structure is so great that it would require a vast number of skilful dissections and engravings to make a correct portrait.

 

Fortunately, this is not necessary for the general reader, who requires only to understand the position of the
organs in the head, and the direction of their growth, which is in all cases directly outward from the central region or ventricles, so as to cause a prominence of the cranium--not a "bump," but a general fulness of contour.

 

Bumps belong to the growth of bone--not that of the brain. Let us next consider the genesis of the brain, which will give us a more perfect understanding of its structure, by showing its origin, the correct method of estimating its development.
