In addition to presenting in meticulous detail all necessary information regarding proper care of laboratory animals, this volume contains a general chapter, by Major C. W. Hume. M.C., B. Sc., on law and practice in relation to the rights of these important partners in medical research. The discussion contains historical notes and a presentation of basic principles that should be required reading for every laboratory worker, from director to bottle washer. Carrying the subtitle, "Hand-book of the Universities Federation for Animal Welfare," the book contains contributions from numerous reliable sources. There is some lack of orderliness in the approach of the various chapters as a result, but this is unimportant. All chapters include details on stock accommodation and equipment, feeding, handling and marking, breeding, anesthesia and species diseases and their control. Sixty-three illustrations, including diagrams and photographs of pens, cages and tanks, add to the practical value of the discussion.
