    j figure, the number ioo. A very simple arithmetical opera- tion gives the proportion— forearm x ioo humerus the quotient obtained furnishes the index. The index is less than ioo if the forearm is shorter than the bone of the arm. The index is more than ioo if, on the contrary, the forearm is longer. In man, the radius is shorter than the humerus ; indeed, in adult individuals of the white race the average index is 74. In the bear, the length of the radius approaches closely to that of the humerus ; the index is about go. In the skeleton of a bear in the anatomical museum of the École des Beaux-Arts, the humerus is 33 centimetres in length, and the radius 30 centimetres. In the cat, the radius is very little shorter than the humerus. In the dog they are equal. The antibrachial index of the latter is, accordingly, 100. In the horse, the radius is longer than the humerus ; the index is therefore above 100. Thus, in the skeleton of the horse which we have in the museum of the École des Beaux Arts, the index is 113—length of humerus, 29 centimetres; length of radius, 33 centimetres. In other skeletons which we have measured we found : in one, 108—humerus, 34 centimetres ; radius, 37 centimetres ; in another, 116— humerus, 25 centimetres ; radius, 29 centimetres. The metacarpal bone undergoes, relatively to the humerus, a proportional elongation, analogous to that of the forearm. In man, the length of the metacarpus is contained about 5-J- times in that of the humerus ; in the bear, it is contained 4 times ; in the dog, times ; in the horse, ij times only. It is well known that the proportions vary according to race, and that what we have here given are but the general indications. The Articulations of the Anterior Limbs The knowledge of human arthrology which we presume the reader to have previously acquired makes it unnecessary for us to enter into numerous details regarding the configura-
