 (16) the phalangeal articulations; (17) the pisiform; (18) the unciform pro- 

 cess of the unciform bone. 



Incisions. (i) From the acromion to the end of the middle finger ; (2) from 

 the sterno-clavicular articulation to the acromion ; (3) from condyle to condyle ; 

 (4 through the metacarpo-phalangeal crease. 



NOTE. In making these incisions care must be taken not to cut too deeply, 

 in order to avoid doing violence to the cutaneous vessels and nerves. Now 

 remove the skin very carefully and expose the following cutaneous nerves and 

 veins :
