Bickets. 215 



spine. The humerus has an outward and forward curve at the 

 insertion of the deltoid, and the internal condyle is unusually 

 prominent. The radius and ulna are bent towards the ulnar 

 side, having thus a curve with its convexity forwards and 

 outwards. B. C. i. 3. M. 31. 



6. 33. Distortion of the Upper Limb from Rickets.— Bones 



of the left arm and shoulder girdle — macerated, to show the 

 above. 



This specimen was taken from the same person as the 

 foregoing, and shows changes similar in kind but varying in 

 degree. B. C. i. 3. M. 32. 



6. 34. Distortion of the Radius from Rickets. — Radii from 

 the same case as that from which No. 6. 31 was taken. 



The bones are bent forward about the middle, and there is 

 a great hollow on the anterior surface, at the junction of the 

 upper and middle thirds, caused by an undue prominence of 

 the ridges on either side, and by the bending forward of the 

 bone at this spot. The upper ends of the bone are rotated out- 

 wards, hence the bicipital tubercle looks directly forwards. 

 The lower end of the bone is relatively enlarged, but the bones 

 are otherwise stunted. B. C. i. 3. M. 30. 



6. 35. Distortion of the Ulna from Rickets. — Left ulna (head 



wanting) from the same case as the preceding — macerated, 

 showing the above. 



The bone is stunted in length and thickness ; the upper 

 end is relatively enlarged, and is bent inwards from the rest 

 of the shaft. The articular surfaces are diminished in size and 

 altered in shape, as if movement at the elbow had been limited.
