The work of Dr. Garrod supplies a want that has long been felt on this side of the Atlantic. It gives a succinct but accurate account of the natural history, of the physical and chemical properties of the articles of the Materia Medica, and of the adulterations to which they are frequently subjected; the physiological action and the therapeutic application of Medicines are very concisely given, but the absence of confused and sometimes contradictory details is often an advantage to the Student. The Editor has confined himself to supplying a few of the omissions of Dr. Garrod, and to indicating, where a difference exists, the preparations of the Pharmacopoeia of the United States. His aim has been to make such additions only as are strictly necessary for the American Student, keeping in view constantly the plan and scope of the original work.
