The Scales
of the Slide Rule 2/83 N
All scales are marked
with reference to the basic scales C and D. At the right.hand
end of the slide rule they bear the mathematical formula based on the numbering
of the basic scales. The cursor, entirely surrounding the slide rule, enables
each stage of the calculation to be connected with the next, throughout all the
scales on the front and back of the slide rule.
