5. Ilandbuch der Mineralog ie ; von Dr. Carl Hintze. Erster 

 Band, vierzehnte Lieferung, Pp. 2081-2240, Leipzig, 1911 (Veit 

 & Comp.) — This is the twenty-sixth part of Hintze's Handbuch, 

 and although more than twenty years have passed since Part I 

 was issued, the author's work is no less careful, accurate and 

 thorough than at the beginning. The species halite, or rock salt, 

 occupies nearly 230 pages, or practically the whole of the present 

 issue. 



6. Catalogue of th e Minerals of Tasmania. Pp.221. Hobait, 

 1910. — A second edition of the Catalogue of Tasmanian minerals, 

 by W. F. Petterd (see vol. iii, 352, 1897), will be welcomed 

 because of the remarkable variety of species which the island 

 has afforded. Three hundred and fifty-six species are discussed 

 in this pamphlet of more than 200 pages, and among these we 

 note the following names which have not appeared in the Jour- 

 nal: Hatchelorite (p. 22) is a hydrated silicate of aluminium 

 occurrinjr in green foliated or slaty masses, as nodules in schist, 

 at the Mt. Lyell mine. Hardness = 4 ; specific gravity = 3'3. 

 An analysis by G. F. Beardsley gave: Si0 2 49-4, A1„0 3 45-1, 

 H„0 5 - 6 = lOl'l. — The name was given by J. W. Gregory in 

 1905 after W. T. Batchelor ; it had been called pyrophyllite. 

 Stichtite (p. 167) is a hydrated carbonate of magnesium, chro- 

 mium, iron, named after Mr. Robert Sticht. It forms foliated to 

 compact masses of a lilac color occurring in serpentine at Dundas 

 near the Adelaide mine. It had passed earlier under the name 

 of kiimmererite. In addition to much interesting information 

 in regard to many different species, is to be noted a full account 

 of the remarkable crocoite of Tasmania, with mention of several 

 new crystal forms. 



7. The Minerals of Guanajuato, Mexico. — Dr. E. Wittich 

 has given a list of the large number of species occurring in the 

 mining district of Guanajuato. Among the points of interest 

 brought out may be noticed the existence of bismuth in the Sierra
