We have to acknowledge the fourth volume of A Manual

of Medicine, edited by W. H. Alkhin, M.D. (Macmillan and Co., 7s. 6d. net). This volume is devoted to "Diseases of the Respiratory and of the Circulative Systems [i.e., the Heart and the Blood Vessels]," and consists of contributions from six writers (including the editor). The subject is, of course, too technical for these columns ; but we may mention that the first ailment discussed is "a cold in the head," and that according to this, the latest available authority, medicine has not discovered either the cause or the remedy.
