Repair of Injuries. 15 



but over the first phalanx and metacarpal bone the subcutaneous 

 tissue had been exposed, and has become covered with granu- 

 lations. These are seen to be small irregular swellings, containing 

 numerous blood-vessels, Avhich have been freely injected. The 

 section shows that the vascularity is much greater in the outer 

 than in the inner parts. G. C. 3075.

1. 50. Scar after Healing* by Granulation. — Portion of skin 

 which has formed the face of a stump, which had healed up by 

 granulation, — in spirit. 



The surface shows great puckering round the central scar 

 and considerable condensation of the tissues in the deeper 

 aspect, illustrating the large amount of fibrous tissue formed in 

 healing by granulation as well as the contraction which ac- 

 companies the process. W. C. Q. 52. 



1. 51. Contraction from Healing by Granulation.— Plaster 



cast of neck and face of a man (Broggan), showing the 

 contraction which attended the healing of an extensive burn, 

 by granulation. 



The patient had been burned in childhood. The chin is 

 brought down upon the sternum, and the lower lip has been 

 pulled away from the mouth. Owing to the loss of support 

 usually given by the lower lip to the lower incisor teeth, these 

 have been pushed forward by the pressure of the tongue from 

 within. G. C. 3166. 



From a Cast presented by John Mackintosh, F.R.C.S.E., 1834.
