Soft cover. Condition: Very Good. London Royal Society 1825 A Very Good+ extract in modern red wrappers with white title label front cover from Phil. Trans. Vol. 115, 1825, pp. 87-130 with foxing, stain lower corner of engraved plates affecting small portion of images. Sm. 4to. Includes 3 engraved plates. Very Good+ Of greater importance was Whewell's work in mineralogy. In a paper read before the Royal Society in 1824, Whewell, according to Herbert Deas, "Laid the foundations of mathematical crystallography." His system for calculating the angles of planes of crystals assumed that crystals are aggregates of small rhomboids that can be thought to shrink below the level of possible measurement, thus suggesting that crystals are latticelike.

(London, G. and W. Nicol, 1825). 4to. No wrappers as extracted from "Philosophical Transactions" 1825 - Part I. Pp. 87-130 and 2 engraved plates with many figs. Upper right corner dampstained, mostly on the first page and here only slightly touching a few letters. First appearance of this importent paper in which Whewell gave crystallography a mathematical foundation."In a paper read before the Royal Society in 1824, Whewell, according to Herbert Deas, "laid the foundations of mathematical crystallography." His system for calculating the angles of planes of crystals assumed that crystals are aggregates of small rhomboids that can be thought to shrink below the level of possible measurement, thus suggesting that crystals are latticelike. In 1825 Whewell visited Mohs in Germany. In 1828, the year in which Whewell became professor of mineralogy, he published a revision of Mohs?s system of mineralogical classification."(DSB).
