The chapter discusses two publications: "The Anatomy of the Rat" by Eunice Chace Greene and "The Hawfinch" by Guy Mountfort. 1. **The Anatomy of the Rat**: - Originally published in 1935, this book is an atlas and textbook that provides a comprehensive account of the rat's anatomy. - It was the only complete reference to H. H. Donaldson's "The Rat" (1924), which contained detailed quantitative data on the weights and dimensions of various body parts from birth to maturity. - The book has been reprinted and is now priced at $25, with minor blemishes from the first edition persisting. - The only significant weakness is the lack of detailed information on the brain, which has become increasingly important in experimental neurology. 2. **The Hawfinch**: - This monograph provides a detailed study of the hawfinch, a less familiar bird species in Britain due to its wary habits and local distribution. - The author, Guy Mountfort, has a particular interest in the hawfinch and has conducted extensive observations over many years. - The hawfinch is noted for its large bill, powerful jaw muscles, and ability to crack cherry stones and olive kernels with crushing loads up to 150 lb. - It is also a strong flier, capable of almost vertical take-offs and bursts of speed approaching 40 mph. - The book covers various aspects of the hawfinch's life, including its aggressive behavior, courtship rituals, nesting habits, song, diet, and distribution. - An appendix by John Boulton provides information on the flight of the hawfinch. - A bibliography of 690 titles could not be included due to publication costs.The chapter discusses two publications: "The Anatomy of the Rat" by Eunice Chace Greene and "The Hawfinch" by Guy Mountfort. 1. **The Anatomy of the Rat**: - Originally published in 1935, this book is an atlas and textbook that provides a comprehensive account of the rat's anatomy. - It was the only complete reference to H.
