The Principles of Insect Physiology
註釋Insects provide an ideal medium in which to study all the problems of physiology. But if this medium is to be used to the best advantage, the principles and peculiarities of the insect's organization must be first appreciated. It is the purpose of this book to set forth these principles so far as they are understood at the present day. There exist already many excellent text-books of general entomology; notably those of Imms, Weber, and and Snodgrass, to mention only the more recent. But authors have necessarily been preoccupied chiefly with describing the diversity of form among insects; discussions on function being correspondingly condensed.
