The article discusses several academic works published in 1931, highlighting their significance and contributions to their respective fields. It begins by praising Sir James Frazer's appreciation of Baldwin Spencer's work, which is considered a unique and valuable record of cultural anthropology. The article then moves on to a monograph on nucleic acids by P. A. Levene and Lawrence W. Bass, which provides a comprehensive overview of the structure and function of nucleic acids, their components, and the enzymes involved in their decomposition. The authors emphasize the importance of phosphorus compounds in cellular processes and the need for a monograph to consolidate existing knowledge. The text also reviews a textbook on plane trigonometry by B. B. Bagi, which is tailored for Indian colleges and includes a variety of topics and examples. Finally, it discusses two works by Prof. Gino Loria: one on the history and bibliography of geometry, which has been revised and expanded, and another on the history of mathematics in the 16th and 17th centuries, which provides a detailed account of the contributions of key figures in the field. The article underscores the importance of these works in advancing knowledge in their respective disciplines.The article discusses several academic works published in 1931, highlighting their significance and contributions to their respective fields.
