Actual Size 5X3 mm.] portional development of gray matter, as well as the size of the tracts, has practically the same connotation as in the lower form already described. Thus, sensory conduction from the leg and tail, head and face is less amply represented than that from the arm and neck. The significance of this rela- tive disproportion is obvious at a glance. The head, forearm and the hand are.
