The review praises a periodical for its quality and expresses gratitude to its publishers. It criticizes the work for implying that the eastern hemisphere stopped contributing to the science of high frequency alternating currents in the early 20th century, noting that key figures like Clerk Maxwell and J. J. Thomson are referenced but the book's treatment of the subject is flawed. The book includes a comprehensive bibliography with 121 references, mostly American. The review then discusses "An Introduction to Medical Statistics" by Hilda M. Woods and William T. Russell, highlighting its usefulness for understanding vital and medical statistics. The book provides essential information for readers to understand official reports on these topics, covering the nature of data, tabulation, charts, population estimates, and statistical methods. The book is well-formatted and suitable for those needing basic statistical knowledge. The review concludes that the book deserves wide circulation. It also briefly reviews two other books on race and racial mixture, noting their differing perspectives on the importance of the topic for global public policy. The first book advocates for racial segregation, while the second explores intermarriage and miscegenation.The review praises a periodical for its quality and expresses gratitude to its publishers.
