gems, jade, Broken Bangle

Sinkankas: A greatly enlarged and completely rewritten edition, expanded in all parts, and with the addition of many more analyses, property determinations, and new species, etc. First mention of the Leske collection of minerals, numbering some 7,331 specimens, which Kirwan notes “hitherto its treasures have been unveiled only to my eyes.” Many of his specific gravity and fusibility determinations were performed on specimens from this collection (the details of which, and its catalog, are described under Karsten, D. L. G., which see). Some notes on the acquisition of this collection by Irish “patriots” are given by Kirwan and are highly interesting. The arrangement of matter follows closely that adopted in the first edition, with most of the gemstones being described in the first volume, p. 241–337. A good précis of this edition by Franz von Kobell, Geschichte der Mineralogie, 1864, 152–4. There is a 3rd ed., London, 1810; GS 11–135.
