In addition to bringing the book into conformity with the Ninth Revision of the U. S. Pharmacopoeia, there has been a thorough revision throughout. The sections on alkalies, pituitary, salvarsan, bichloride poisoning, emetine, oxygen, and ergot have been rewritten, and new articles have been introduced on benzine and gasoline, benzol, kaolin, fullers' earth, glucose, papaverine, ethylhydrocupreine, phenylcinchoninic acid, magnesium sulphate, oil of chenopodium, and the Dakin-Car-rel antiseptic treatment for wounds.

Because of its universal use in medical literature the term cubic centimeter (c.c.) has been retained, though the U. S. and British Pharmacopoeias have substituted the term milliliter (mil.). A milliliter differs from a cubic centimeter by such a small fraction that it is quite negligible.
