Excerpt from Laboratory Directions for an Elementary Course in General Zoology These laboratory directions represent the outline of the lab oratory course in general zoology as developed in the University of Illinois. The original plan of the course was formulated by Professors Henry B. Ward and Charles Zeleny. Individual out lines throughout the course represent the work and suggestions of numerous persons who have, at various times, been connected with the instructional staff in general zoology. 'the form found in the present volume is the result of many revisions and altera tions of the several mimeographed and printed editions which have been used with classes through a period of a considerable number of years. In recent revisions the cooperation of Profes sor V. E. Shelford has been especially valuable. An attempt has been made to secure a fair distribution of emphasis through a number of the more important aspects of the subject.
