Legend: Illustrations include: COPERNICAN SYSTEM:  or Hypothesis, that system of the world wherein the sun is supposed at rest in the centre, and the planets, with the earth, to move in ellipses round him. The sun and stars are here supposed at rest, and that diurnal motion which they appear to have from east to west, is imputed to the earth’s motion from weft to east, round its axis. CRANES COMPOSITION OF MOTION:  or Force, in mechanism, is an assemblage of several directions of motion resulting from powers acting in different, though not in opposite lines. CONICK SECTIONS: curves formed from the section of a cone by a plane. The curves that generally pass under the name of conick sections are three, viz. the ellipsis, parabola, and hyperbola ; for though the triangle and circle are formed from the section of a cone, yet they are not usually considered in that capacity. Hard copy of the legend (for CRANE) is not part of this offer. (the letter that looks like f, represents the letter s). Martin2001 Satisfaction Guaranteed Policy!
