5776. The third lumbar vertebra, vertically and longitudinally bisected. 



Here the walls of the cancelli of the centrum decussate at right angles, intersecting minute 

 quadrangular spaces. 



Prepared in 1851. 



5777. The sacrum, vertically and longitudinally bisected. 



It shows the vacant spaces between the centrums, which have retained a remnant of the 

 intervertebral substance. 



Prepared in 1851. 



5778. The sacrum, transversely bisected through the middle of the second vertebra. 



Prepared in 1 8 5 1 . 



5779. The body of the sternum, longitudinally and transversely bisected. 



It is remarkable for the extremely thin, scarcely recognizable, layer of the external compact 

 tissue, which encloses the uniformly fine cancellous texture. 



Prepared in 1 8 5 1 . 



5780. The first rib, longitudinally bisected. 



It shows the superior thickness of the compact texture forming its concave margin. 



Prepared in 18 51. 



5781. A sixth rib, longitudinally and horizontally bisected. 



t 



The difference of thickness of the compact wall at the concave and convex margins is 

 only perceptible towards the middle of the rib, and is much less marked than in the 

 first rib. 



Prepared in 1851. 



5782. A sixth rib, longitudinally and vertically bisected. Prepared in 1851. 



5783. The clavicle, longitudinally bisected. 



The compact wall is thickest at the concave side of each of its curves. 



Prepared in 1851. 



5784. The scapula of the left side, transversely bisected through the middle of the 

 glenoid cavity. 



It shows the character of the diploe at that part, its absence in the thin compact body of 

 the scapula, and its reappearance in a minute quantity in the thickened basal border. 



Hunterian. 



5785. The upper moiety of a similarly bisected scapula, in which the texture of the 

 coracoid and acromion is exposed in longitudinal section. Hunterian.
