An elementary treatise on analytical geometry : embracing plane co-ordinate geometry, and an introduction to geometry of three dimensions
A textbook of analytical geometry by William Woolsey Johnson, published in Philadelphia by J.B. Lippincott in 1869 for American college students studying plane coordinate geometry and solid geometry. The 46 figures are line-engraved conic sections — ellipses, hyperbolas, parabolas — crossed by tangents, chords and axes and labelled with serif capitals, usable as spare geometric line motifs and diagram fragments.
