In the fifth edition of "Diagnostik der Kinderkrankheiten" Dr. Feer has once again attempted to present the elements of pediatric diagnosis in the form of a timely practical handbook for medical students and busy practitioners. Following the semeiotic arrangement employed in previous editions the author draws on his extensive pediatric experience to provide a wealth of accurate diagnostic detail in a refreshingly familiar style. Although the spectrum of pediatric diagnosis is, in general, covered admirably, certain important aspects are neglected. Problems peculiar to the diagnosis of virus and parasitic infections in childhood receive little attention; only the bare elements in the diagnosis of deficiency diseases and endocrine disturbances are discussed; and the fields of acute and chronic poisoning, as well as the subject of malignancy in childhood, are incompletely elucidated.
