This monograph is the result of twenty years of study on five thousand subjects. The subjects are grouped as to their complaints, medical history, physical examination, laboratory findings and special examinations. The result is therefore an actual experience as to the response of patients with endocrine disturbances to the foregoing factors. The results are interesting and show that in actual experience the so-called classic symptoms of the endocrinopathies are not so frequently apparent as one is led to believe. This book should be of value to any physician who wishes to know the actual findings in endocrine disturbances. It is interestingly written and is well printed.
