The recent expansion of the field of photomicrography has been a great help to today's biologist. With the photomicrograph the student of biology can more easily grasp biological details. However, some fields of biology have been slighted in this regard. Embryology is one of these fields. In this dissertation I wish to illustrate that efficient, modern embryological study warrants the extensive use of photomicrographs.

In the modern trend of education there is a definite favoritism shown toward visual aids. The purpose of this work and research is to show the feasability of using visual aids in the study of embryology. Before going on it is necessary to show that the contemporary method has certain deficiencies. Let us analyze this method. By doing this we can see many inconveniences and we can propose newer ways of covering the material throughout the course.

The main aspect to be considered in this work is that of the laboratory section. Embryology demands a great deal of study in the laboratory. Practically speaking, hours of work go into the viewing of slides, the drawing of plates, and the observation of lab material. Although there is no quick, easy way of grasping this portion of the course, efforts can be made to ease the work for the student. If this could be accomplished the student would have time to cover more material, have more time to study his other courses, or possibly both.
