Before presenting our observations in a limited number of cases it may be of interest to call attention to similar uses of mercury by other authorities.

Sicard,1 in 1913, reported the use of mercuric cyanid in doses of from 0.1 to 0.2 mg. combined with 1.5 cg. of novocain in 2 c.c. of normal salt solution raised to a temperature of 100 C. and injected intraspinally.
