The unused scapula is much more delicate than theused scapula, and, as shown in the photograi)h. has on theoperated side an area in each of the supra- and infraspinatusfossae, which is covered only by a membrane, bone being entirelyabsent. The trabeculae, particularly in ilic humerus, show interestingdifferences (fig. G). In the bones of the used
