This is a well-written book, expertly produced, profusely illustrated, and documented by an extensive bibliography. It summarizes what is known about the blood of both vertebrates and invertebrates. There is an attempt to show the evolution of the development of hemopoiesis based on both functional and structural changes. Structural changes are evaluated in terms of light, phase, and electron microscopy wherever possible.
The book will be of value to those interested in comparative hematology, and will be useful as source material to those looking for hematologic values in some of the less familiar animal species.
