This book of 384 pages is essentially a catalogue of drugs listed in the U. S. Pharmacopeia with a brief statement of origin and general character of the drugs. It is essentially an enlarged model of Useful Drugs (A. M. A.) and, as stated in the preface, does not attempt to present to the medical student a pharmacologic basis underlying clinical usage of the drugs. Such a book as this appears to be entirely uncalled for and would seem to have no place in the teaching of modern pharmacology and therapeutics to medical students.
