HOW TO USE DISSECTING INSTRUMENTS. 



§ 590. Hyrtl complains (A, 62) that " some people liold the for-

 nerves that whatever instrument is in his hands becomes for the 

 time being like a part of himself, an extension of his fingers, sharper, 

 firmer and more slender, yet almost equally mobile and sensitive.

 upward or downward. This is for the division of more resisting 

 tissues. 



C. LiJce a Violin-bow (Fig. 65).— The scalpel is held between the 

 tip of the pollex on one side and the tips of the other digits upon the
