Outlines of Physiology, Human and Comparative. By John Marshall, F.R.S.

2 vols. (Longmans.)—So far as we can judge, this work is executed with much completeness, and presents "a concise but compre- hensive summary of modern Physiological Science." The parts which we have examined are very clear and fall, while the accompanying woodcuts make the descriptions generally intelligible. A. work of so much labour demands, it is true, a fuller and more careful criticism than it is possible for it to receive at the hands of a mere literary judge, whose only task is to eater for the taste of miscellaneous readers. But even miscellaneous readers want books on which they can rely for solid information, and the critic may sometimes act as a finger-post, even when he cannot aspire to the dignity of being a handbook.
