Two vintage antique math books covering differential equations & slide rule still my heart! ;) Lots of % () # + = & the like!

An Elementary Treatise on Differential Equations by Abraham Cohen PhD
Professor of Mathematics Second Edition Completely Revised DC Heath & Co 1933

Versalog Slide Rule Instructions by E.I. Fisenheiser B.S. M.S. C.E.
Professor of Civil Engineering The Frederick Post Company 1951

Both are worn to shabby vintage perfection! Some yellowing, pencil & pen
marks & a bit of mustiness with a teeny hint of pipe smoke from years on a
library/study bookshelf no doubt!

In good vintage condition.
