Description
The citation information for this 16-page pamphlet is Charles Bruning Company, Inc., Instruction Manual for Bruning Slide Rule No. 2401 (New York, 1944).

After explaining the parts of a slide rule, the manual divides the process of learning to use a slide rule into twelve steps, each of which are discussed with examples, solutions, and exercises in the remainder of the pamphlet.
