The Rat

"The Rat Second Edition Revised" is a comprehensive and foundational scientific reference work dedicated to the biology, growth, and physiological data of the albino rat. Compiled by Henry H. Donaldson, this classic volume serves as an essential resource for researchers and students of zoology and medicine. The work meticulously catalogs physical measurements, anatomical details, and growth patterns, providing a standardized baseline for laboratory studies.

Covering topics from skeletal development and brain weight to the chemistry of the body and lifespan, "The Rat Second Edition Revised" remains a significant historical text in the field of experimental biology. By consolidating decades of observational data into a single, structured format, Donaldson established a crucial standard for the use of the rat as a model organism in scientific inquiry. This volume is invaluable for those interested in the history of science, comparative anatomy, and the development of modern laboratory practices.
