The Pedestrian's Record

THE PEDESTRIAN'S RECORD. 213 acts powerfully in bringing the ulna and the humerus into a straight line. When the arm is extended it has the power,with the assistanceof the teresmajor and latissimus dorsi, of drawing it backwards. These muscles are actively engaged during pugilistic encounters. Numerous muscles are insertedupon the thumb and phalanges, taking their origin from thesuperimposed bones, description of which wouldbe oflittle interest to the general reader, especially as the platesufficiently indicate he disposition of the muscular arrangement of the wrist and fingers. THE INSIDE OF THE ARM. The deltoid, biceps, and triceps have been already considered. The carpaland palmar muscles are numerous and important, and thosesuperficially situated are well delineated on plate 4, such as the flexorcarpi ulnaris andthe adductor of the little finger ; and as anelaborate description of them would beof little service to any excepting anatomists, we shall leave the plates to the examinationof our readers. ANTERIOR MUSCULAR FORMATION OF THE THIGH AND LEG. The sartoriusarises from the ip, and is inserted on the inner and upper side of the tibia. It occupies the front part of the thigh,and descends downwards from the hip in an oblique direction to its insertion, where it sends off an expansion of tendinous structure which gives strength to the capsule of the knee-joint. Rectus femoris is situated in the front part of the thigh, taking a straight line downwards from the pelvisto thepatella, or knee-cap. It arises by two tendons which unite. This muscle increases in size about its middle, and then again diminishes to its insertion on thetibia. Vastus externus and internus are placed on each sideof the femur, the one on the outside, and one on the inside, as
