The student should make himself tlkoroughly familiarwith the general plan and structure of the skeleton,and with the names, positions, and shapes of its variousbones, since the general direction, and the names ofthe bones, determine the direction and the names of alarge number of the blood-vessels, nerves, muscles, &c., towhich they are adjacent.
