No. 3. A third specimen consists of the lower half, or rather more, of the right _femur_. The least circumference is 3″·2. The bone exhibits no special external characters, and is in no degree carinated. The shaft, at about the middle of its length, is somewhat angular in front; and the pit for the origin of the _popliteus_ muscle is deeper and perhaps larger than in most bones of the same size. The texture of the cortical substance is quite eburneous; and it is extremely thick, so that the medullary canal is reduced to a calibre of little more than 0″·25 in its longest diameter. The shaft, however, is straight, and exhibits no other sign whatever of having been affected with _rachitis_. It is, however, a curious circumstance that many of the Gibraltar thigh-bones, most of which are carinate, present the same thickening of the cortical substance (Fig. 57). No. 4. A fourth specimen is constituted of merely a portion of the shaft, about 12 inches long, and without either extremity. Its least diameter is 3″·3, and its antero-posterior and transverse diameters, at the same point as in the other bones, 1 × 1·25, or pretty nearly in the usual proportions. Nevertheless the bone, throughout its whole remaining extent, is less rounded on the inner side of the shaft than is usual. The _trochanter minor_ is of gigantic size; and the shaft of the bone, about and below the middle, exhibits a subtriangular aspect (Fig. 58), though scarcely to be called carinate. The cortical substance is of the normal thickness. III. _Tibiæ._--No. 1 consists of the greater portion of the left tibia, wanting only the lower extremity. The proximal end measures 2·9 × 1·9; and the diameters of the shaft, about the middle, are 1·2 × ·75, giving a latitudinal index of ·620. The shin is remarkably sharp and prominent, and rather curved over to the outer side; and the apparent compression or tendency to platycnemism may in some measure be referred more to the production in front of the anterior part of the bone than to actual narrowing of the posterior side of the triangle, which is nevertheless rather more rounded than in most cases. The axis of the shaft is quite straight; and the bone has not the least rickety appearance. No. 2 is also a portion of the left tibia. Both extremities are wanting, and the bone offers nothing worthy of remark. Its least circumference is 2″·65; and the shaft, at the middle, measures 1″·1 × ·65; so that the latitudinal index is about ·640, showing a slight degree of compression. The entire length of the bone may be estimated as rather more than 13 inches, corresponding to a height of about 5 ft. 4 in. or 5 ft. 5 in., so that the subject may be supposed to have been a female.
