Malher & Cie

First French edition of this important study. Translation from English with notes by MM. Verhulst and A. Quetelet. The second volume is from 1833. The significant publication delay between the first and second volumes allowed for some remarkable additions: Supplement to the treatise on light by Quetelet, p. 336-602 of volume 2, in which the latter exposes recent research in optics. The illustration comprises 15 folding plates. The treatise on light had only appeared in the form of articles in the Philosophical transactions, and this is its first edition in volume form to which Herschel contributed with his corrections.
Full olive green sheep bindings, slightly later ca 1840. Sm

First edition of the French translation established by E. Pelouze.
Half aubergine sheep binding, spine lightly browned without consequence with four raised bands decorated with gilt fillets and fleurons, date at foot, marbled paper boards, marbled endpapers and pastedowns, original wrappers preserved.
