NO RESERVE Chaulnes (Michel Ferdinand d'Albert) Nouvelle méthode pour diviser les instruments de mathématique et d'astronomie, first edition, 15 engraved plates, plates crudely stitched, contemporary marbled boards, light wear to spine ends, a little rubbed, preserved in custom drop-back box, [Tomash & Williams C75,] folio, [Paris, L. F. Delatours], 1768.⁂ "In this work Chaulnes describes two dividing engines of his invention: one for dividing circles and the other for dividing linear scales. First published in the Description des Arts et Metiers, Volume 13, it appears here separately in a large format... The use of the Chaulnes machine eliminated the need for a highly skilled craftsman when creating precision scales. Chaulnes used microscopes of his own design (also described here) to read the divisions on his scales. He also incorporated a screw drive mechanism to move his engraving tool, and this was the first publication to present to that technique." - Erwin & Tomash.
NO RESERVE Roget (Peter Mark) Description Of A New Instrument For Performing Mechanically The Involution And Evolution Of Numbers, extract from "Philosophical Transactions of the Royal Society of London", vol. 105, pp.9-28, 3 engraved plates (2 folding, 1 trimmed at outer margin), disbound, [Tomash & Williams R104], 4to, [1815].⁂ "It was Roget who invented the concept of the log-log scale that was later universally adopted as one of the standard scales on a slide rule. Its value was not immediately appreciated because the need for this scale only became apparent when various formulae, containing non-integer exponents in thermodynamics were developed. Roget's scale was forgotten, and various unwieldy schemes were proposed for handling the until Roget's scale was rediscovered in 1901." - Tomash & Williams.
