Fonteyne, A., concludes that (1) respirations become more and 
more frequent in proportion to the injections; (2) the volume of 
air expired per minute likewise increases progressively with the in- 
jections, being twice as great as normal with doses of 16 gm. ; (3) 
the volume of air expired with each respiration increases likewise 
with each injection of benzoate of soda. He discusses the action of 
sodium benzoate on respiration, gives some general conclusions, and 
a number of historical and pharmacological references. — Arch, in- 
ternal. de pharm. et de therap. Par., 1906, v. 16, pp. 396-403, 449 ff.
