306 Transactions. — Zoology. 



smooth surface, greatest height 6 in. 6 lines ; antero-posterior diameter, 



6 in. 10| lines; transverse diameter, 5 in. 6 lines; breadth at zygomatic 

 arches, 5 in. 4 lines ; breadth of upper jaw over third molar tooth, 2 in. 



7 lines ; length of base of skull from symphysis to anterior margin of occipital 

 foramen, 3 in. 7| lines ; length from symphysis to anterior margin of occipital 

 crest, 6 in. 9 lines ; length from symphysis to occipito-parietal suture, 8 in. 



Lower jaw. — Depth at symphysis, 1 in. 3 lines; depth at coronoid process, 

 2 in. 6 lines ; breadth between angles of jaw, 3 in. 4|^ lines ; breadth between 

 condyles, 3 in. ; breadth of space over the last molar tooth, 2 in. \^ lines. 



Length of skeleton articulated. — Head, greatest height, 6 in. 6 lines; 

 body, including the entire spine, 2 ft. 5 in. 6 lines. Total length of skeleton, 



5 ft. 7 in. 9 lines. 



In the living body allowance must be made for the curvatures of the 

 spine, the elongation of the sacrum beyond the hip joint, and the position 

 of the foot, so that the height would probably be about five feet from the 

 crown of the head to the sole of the foot. 



Pelvis. — Greatest depth, 7 in. ; greatest external breadth, 9 in. 6 lines ; 

 depth of symphysis, 1 in. 6 lines ; brim, antero-posterior diameter, 5 in., 

 transverse diameter, 5 in. 



Thoracic locomotive organs. — Humerus, 11 in. 3 lines; radius, 8 in. 



6 lines ; carpus, 1 in. 3 lines ; metacarpus of third finger, 2 in. 6 lines ; 

 phalanges of third finger, 3 in. 3 lines. Total, 2 ft. 2 in. 9 lines. 



Pelvic locomotive organs. — Femur, 1 ft. 4 in. ; tibia, 1 ft. Oin. 9 lines ; 

 height of foot, 3 in. Total, 2 ft. 7 in. 2 lines. Length of foot, 8 in. 3 lines. 



Weights. — Skull, 1 lb. 8 oz. ; lower jaw, 3 oz. Total weight of head, 

 lib. 11 oz. 



Body, including cervical, dorsal and lumbar vertebrae, together with the 

 ribs and sternum, 1 lb. 8 oz. ; pelvis, including sacrum and coccyx, 12 oz. ; 

 scapulae, 3 oz. ; clavicles, 410 grs. ; thoracic locomotive organs (arms), 12 oz. ; 

 pelvic locomotive organs (legs), 2 lbs. Total weight, 6 lbs. 14 oz. 410 grs. 



The usual weight of an adult human skeleton varies from 10 lbs. to 

 12 lbs. 8 oz., but, as I have already alluded to the greatly altered condition of 

 the bones in the case of this skeleton, little importance can be attached to 

 the weight as compared with others in which the bones still retain the 

 original osseous tissue.
