Dr. Faught's book offers a practical guide to the use of the sphygmomanometer and the clinical determination of blood pressure. It includes also a general discussion of the interpretation to be placed on blood pressure determinations. The author has combed the literature thoroughly, as is evidenced by numerous references to the most recent periodical literature. So much has recently been written concerning blood pressure that many of the observations of yesterday no longer apply. For this reason Dr. Faught suggests that "the purely scientific investigator should not be too critical of the conclusions drawn" as "the chief effort has been to reduce a very large and complicated subject to a practical working basis."
