This volume is well written and adequately illustrates work on the physiology of the hormones of certain invertebrate animals. The author has condensed his study of these hormones into four primary divisions. One section is devoted to a consideration of cellular hormones: those elaborated by a cell and effective within the same unicellular organism. In another section are considered hormones of aglandular tissue, wherein the heart-stimulating regulators and neural hormones are discussed. A third section is devoted to the glandular hormones, such as sex hormones, hormones regulating metamorphosis and those controlling changes of color of the integument. A concluding section of the volume covers the literature relative to the effect of mammalian hormones on certain representative animals of the invertebrate phyla. The effects of the administration of hormones of the thyroid, pituitary and adrenal glands are discussed. An extensive bibliography is appended. This volume represents a distinct contribution to knowledge
