The anterior foot becomes a hand when the inner finger or thumb is opposable. The great toe of the posterior foot is also sometimes opposable, but the foot does not on this account become a hand, but only a prehensile foot (Apes); for the hand is characterised by the special arrangement of the carpal bones and muscles. According to the manner in which the foot rests on the ground in movement, animals are distinguished as plantigrades, digitigrades and unguligrades. In the last case the number of digits and metacarpals (and metatarsals) is reduced, and the limb is much elongated by the transformation of the metacarpal (metatarsal) bone into a long tubular Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Claus, Carl, 1835-1899; Sedgwick, Adam, 1854-1913; Sinclair, F.
