Commencing with the fore parts of the skeleton, we will first notice the 486 THE HORSES POSITION IN THE ANIMAL WORLD joint Avliich is called the wrist or ccupus, the knee of the horse as it iswrongly named. In this two rows of small bones are arranged, as canhe seen in the figure, between the arm-bone above and the shank-bonesbelow, the latter consisting of one large bone and two small splint-bonesattached to it. In man the corresponding arrangement conduces to a veryimportant end—a series of movements in the hand and arm which are.

The hand of man constantly performs the movements of flexion andextension, as they are called (these being binge-like motions with extensivelateral movement), and in addition almost perfect rotation, at least to theextent of two-thirds of the circle. On the other hand, the horses wristor knee is only capable of flexion and extension. Nearly the same degree and exactly the same variety of movement are SPECIAL FEATURES IX STRUCTURE 487 possible in the elbow-joint of iiiun, wliile in the horse, owing to tlie rudi-mentary form of the second bone of the arm {the ulna),
