The chapter discusses the importance of frequency curves, correlation, and sampling in statistical science, highlighting the contributions of Prof. Karl Pearson and his school. The author emphasizes the practical value of simple and reliable formulas for curve-fitting, especially in actuarial statistics. The third edition of the book includes re-written chapters on standard errors, goodness of fit, and the correlation ratio, while retaining the notation for moments. This review praises C. M. Beadnell's dictionary of scientific terms, particularly its focus on biological terms and concise definitions. The dictionary is noted for its accuracy and accessibility, making it a valuable resource for laypeople interested in science. However, the absence of etymologies is noted as a minor drawback. This second edition of the book by Dr. W. F. Bewley and J. Harnett provides a comprehensive and practical guide to mushroom cultivation, covering all aspects from initial processes to diseases, pests, and cooking recipes. The authors are recognized for their expertise, and the book is well-illustrated with line diagrams and photographs. This textbook by Dr. Frederick Prescott and Dudley Ridge covers the organic chemistry required for second-year medical students and general B.Sc. students. It includes sections on carbohydrates, ureides, purines, proteins, fermentation, enzyme action, hydro-aromatic compounds, indole derivatives, and alkaloids. The book also discusses modern theories of valency, though these may need updating in future editions due to rapid changes in scientific understanding.The chapter discusses the importance of frequency curves, correlation, and sampling in statistical science, highlighting the contributions of Prof. Karl Pearson and his school.
