BREWSTER, DAVID. - PRODUCING DOUBLE REFRACTION IN CRYSTALS.

On the communication of the structure of double refracting crystals to glass, muriate of soda, fluor spar, and other substances, by mechanical compression and dilatation. Read Febraury 29, 1816.

(London, W. Bulmer and Co., 1816). 4to. No wrappers as extracted from "Philosophical Transactions" 1816 - Part I. Pp. 156-178 a. 2 engraved plates.

First appearance of an importent paper in optical theory in which Brewster describes his discovery that double refraction phenomena can be induced by mechanical means on different kinds of crystals by compression and deflection.

Together with Brewsters paper comes a paper by Everard Home "Some account of the feet of those animals whose progressive motion can be carried on in opposition to gravity." Pp. 149-155 and 2 engraved plates.
