CONTRACTION OF THE PLATYSMA. 301 They exhibited some trepidation, but no great terror.In only four of the cases was the platysma visiblycontracted; and it did not begin to contract until thepatients began to cry. The muscle seemed to contractat the moment of each deep-drawn inspiration; so thatit is very doubtful whether the contraction depended atall on the emotion of fear. In a fifth case, the patient,who was not chloroformed, was much terrified; andhis platysma was more forcibly and persistently con-tracted than in the other cases. But even here thereis room for doubt, for the muscle which appeared tobe unusually developed, was seen by Dr. Ogle to con-tract as the man moved his head from the pillow, afterthe operation was over. As I felt much perplexed why, in any case, a super-ficial muscle on the neck should be especially affectedby fear, I applied to my many obliging correspondentsfor information about the contraction of this muscleunder other circumstances.
