Nothing is easier than to familiarize one's self with the mammalian brain. Get a sheep's head, a small saw, chisel, scalpel and forceps (all three can best be had from a surgical-instrument maker), and unravel its parts either by the aid of a human dissecting book, such as Holden's `Manual of Anatomy,' or by the specific directions ad hoc given in such books as Foster and Langley's `Practical Physiology' (Macmillan) or Morrell's `Comparative Anatomy, and Guide to Dissection of Mammalia' (Longmans).
