The passage discusses several books and their contributions to various fields. Mr. Beaver's work on electric cables highlights the use of aluminum conductors due to their lower weight and cost compared to copper, and the challenges of soldering zinc wire. The book "Rambles in Vedānta" by B. R. Rajam Aiyar provides insights into Hindu philosophy and religion, offering a unique perspective influenced by both Eastern and Western literature. Prof. E. H. Kettle's "The Pathology of Tumours" is a valuable resource for medical students, featuring detailed diagrams and a chapter on treatment. Dr. May Sybil Burr's part of "A Text-Book of Inorganic Chemistry" focuses on alkaline earth metals and radium, making it a comprehensive reference. Lastly, Prof. A. Boutaric's "La lumière et les radiations invisibles" offers a non-mathematical survey of light and radiation phenomena, including the behavior of light in gravitational fields and the ether.The passage discusses several books and their contributions to various fields.
