Description
The types included in this volume are commonly studied in elementary zoology courses. Only those processes which are normally performed by the student himself are described, skeletal material and specially prepared sections being omitted because they are adequately explained in most text-books. Such material and sections are, however, an important part of the practical work and should not be forgotten.
The series of drawings is designed to aid dissection with the minimum of written instruction. It is not always possible to show the exact position of the instruments for making every cut, but full indications are given.
The scales of the diagrams vary throughout the book, the aim being to maintain some uniformity when dealing with any one creature and at the same time have the diagrams as large as the pages permit. The scales recorded are only approximate because of the variability of the size of the specimens.
At the conclusion of each section of the work the student should make a fully labelled drawing of his own dissection on as large a scale as possible.
