JF A.M.A. Journal of Diseases of Children JO A.M.A. Journal of Diseases of Children YR 1959 FD June 1 VO 97 IS 6 SP 895 OP 895 DO 10.1001/archpedi.1959.02070010897026 UL http://dx.doi.org/10.1001/archpedi.1959.02070010897026 AB This is a prodigious undertaking for a practicing internist. However, he has successfully woven in a vast clinical experience with current knowledge to present a well-organized, concise, yet informative, discussion of difficult diagnoses. An important aid is Part II, entitled "A Classification and Analysis of Useful Diagnostic Procedures." The value of the text is enhanced further by an extensive bibliography and an index of signs, symptoms, and laboratory manifestations. The chapter on Cutaneous Medicine is well illustrated with an atlas of 99 pictures. An increasingly important subject is well presented in the chapter entitled "Iatrogenic Illness."This book will serve as a valuable addition to the library of both internists and general practitioners.
