The passage discusses the production and consumption of cane and beet-sugar, highlighting the potential for significant expansion in Cuba and India by increasing yields to match those of Java. It also mentions the prediction of recent expansion in India and the likely disappearance of beet-sugar if protectionist policies were removed. The second part reviews a book on European geography by Margaret Reid Shackleton, praising its fresh and sympathetic approach while noting that it is not suitable as a school or university textbook but is recommended for those seeking a broader understanding of European geography. The third part reviews a textbook on differential calculus by Theodore Chaundy, noting its comprehensive and rigorous treatment of the subject, though it is criticized for being self-contained and potentially too complex for some students. The book covers various topics and includes many interesting examples and new terms. The fourth part reviews a book on matrices by J. H. M. Wedderburn, tracing the historical development of matrix theory and its resurgence in the 1920s due to its importance in quantum mechanics. The book is based on lectures and covers a wide range of topics in pure mathematics. The fifth part briefly mentions a book on generalized hypergeometric series by Dr. W. N. Bailey, noting its focus on a function of three parameters discussed by Gauss.The passage discusses the production and consumption of cane and beet-sugar, highlighting the potential for significant expansion in Cuba and India by increasing yields to match those of Java.
