    the arm and hand occupy a considerable space, as might be expected from their importance as organs of intelligence. Area [5] (figs. 26 and 27) is the centre for the forward extension of the arm and hand; area [4], for the adduction and retraction; area [6], for the supination and flexion ; while the various letters (a, &, c, d) placed in the ascending parietal convolution indicate the position of centres for the movements of the wrist and fingers. With these latter, retraction of the angle of the mouth is apt to be associated, owing to the proximity of the facial and oral centres (7, 8, 9, 10, 11, fig. 26): a proximity which serves to explain, among other things, the retraction of the angle of the mouth so commonly seen associated with power- ful action of the hand. Hence also the fact that brachial monoplegia occurs less often than brachio-facial paralysis. a 9 70 Fig. 33. It is obviously highly important, in any given case of bra- chial monoplegia of cortical origin, to determine, if possible, which of the movements of the upper extremity are particularly affected. This has not been done with any great degree of accuracy in many of the recorded cases. M. Maurice Eaynaud' reports a case of paralysis limited to
