Show 48 LONG BONES. There are eight long bones among the remains, viz: 1 humerus, right. ") 1 ulna, right. 1 radius, left. . I A 1 femur, left. fA# 1 tibia, left. I 1 fibula, left. \ evidently belonging with the skull marked No. 1. Besides these are, 1 femur, right. > R 1 femur, left. f Dm which should undoubtedly be correlative with skull No. 2. Description and measurements of banes A. a. Humerus.- If we may judge from what is known in general about the proportions of the humau body, the long bones combined under the head A belonged to a person about 5.6 feet high. The greatest length of the humerus, measured from the apex of the bead to the inner and lower border of the trochlea 32cm. 2 ; greatest diameter of head near the anatomical neck 4cro. 8. Muscular insertions very marked. An-tero- posterior diameter of shaft 7cm. 5 below insertioVi of supra spinatus 2Fm. 2. Transverse diameter 2cm. 4; circumfereuce7c, n. 3. The same measurements in the middle of the bone lcm. 7, 2cm. 3, and6cm. 6, respectively, aud lcm. 5 above the olecranon depression lcm. 8,3cn\ 6, and 9cm. 8. Extreme distance between outermost point of external and innermost ot internal condyle Gcm. l. b. Vina.- Distance from olecranon to articular part of the head of the lower extremity ( styloid process broken )= 26cm. 3; muscular insertions everywhere strongly pronounced. Greatest circumference of shaft measured 3cm. 7 below the highest point of coronoid process, 5CB\ 3; anteroposterior and lateral diameters, in the same plane lem. 8 and. lcm. 6, respectively. c. Radius.- Distance from highest point of head to lowermost of styloid process 24cm. 6; diameter of head 2C m. 2; depression of its upper surface rather deep; ridge for attachment of portion of supinator brevis uncommonly pronounced. The shaft does not offer anything extraordinary. Anteroposterior and trausverse diameters of lower extremity 2cm. 3cm and 3.4, respectively. d. Femur.- The length of the femur, measured from the upper surface of the head to the inner condyle, is 45cm. 5, while the greatest distance between the great trochanter and the outer condyle is 43om. 4. Greatest width measured between the depression for the ligamentum teres and the insertion of the gluteus medius 9cm. 9 ; greatest diameter of head 4C". 6; depression for the attachment of the ligamentum teres is less ovoid than usual, and more of a reniform shape, its two diameters being 2cm. O and lcm. 5, respectively. Keck very strong; greatest horizontal diameter 2cm. 6; greatest vertical diameter 30m. 2; anterior surface withont any vascular foramina and concave, while the posterior surface is more convex than usual. Anteroposterior diameter of shaft lcm. 5 below the base of the lesser trochanter 2om, 5; transverse diameter measured in the same plane 3cm. 4. The same measurements taken in the middle of shaft 2cm. 4 aud 2cm. 3, and 3cn\ 4, above the upper and external border of the trochlear surface 3cm. O and 4cm. 2, respectively. The three cir- |
