RADIOGRAPHIC INTERPRETATION OF THE EPIPHYSES. 587 In Fig. 157, which is a hiteral view of the elbow at fourteen, we find that theprimary centre for the olecranon hasgreatly increased in size and that a second-ary centre has appeared. These usually coalesce during the next six months,giving rise oftentimes to a peculiar elongated body. Here also the shadow ofthe trochlea is superimposed upon the shadow of the capitellum. The shadowof the trochlea is posterior to the shadow of the capitellum, while the shad
