During the course of an embryological investigation, the need arose for an accurate graphic representation that would aid in the interpretation of certain complex structural arrangements. Since many of the structures under consideration were behind others in the same plane of section, it was not possible to show clearly their true location by the usual graphic reconstruction method. If the standard graphic method could be modified to give a three-dimensional illusion, structures might then be shown in their relative spatial positions. Techniques have been published that show the three-dimensional aspect in graphic reconstruction by means of stereoscopic illustrations (Lebedkin, '26 ; Sauer, '37). Lebedkin ('26) reviewed the techniques involved in several types of graphic reconstructions and contributed a modification of the standard technique in an attempt to produce a three-dimensional illusion. Since these methods are not as simple as might be desired, the system presented below was devised in the attempt to produce an accurate three-dimensional illustration simply and directly. It is based upon a simple geometric construction. The basic principles incorporated in the theory of perspective gave the author the solution to the present problem.
