Popis:	The instrument herewith described is an aid in the rapid preparation and interpretation of stereographic and gnomonic projections for a fundamental sphere of radius either 5 or 2 cm. The use of the instrument in solving distance, angle, rotation, and reflection problems is described in elementary fashion illustrated by simple examples. Application of these to the solution of problems in structural geology and morphological crystallography is brought out.
