fined wholly to the former purpose, and in it 777 pages are 

 devoted to the Geology and 235 to the Paleonto]ogy of 1886. 

 It is a work that geologists, whatever their special department, 

 will find very useful if not indispensable. 



6. The Geological Record for 1879. An account of works 

 on Geology, Mineralogy, and Palaeontology published during the 

 year with supplements for 1874-78. Edited by W. Whttaker 

 and W. H. Dalton. 418 pp. 8vo, London, 1887, (Taylor and 

 Francis.) — This comprehensive volume, like its predecessors in 

 scope, will be thoroughly welcome although it is somewhat late 

 in appearing. For the future it is announced that the editorship 

 has passed into the hands of Mr. Topley and the work is to be 

 brought up to date by publishing the titles only of papers from 

 1880-87. The portion from 1880-1884 is finished and in great part 

 printed, making two volumes. That for 1885-87 is in hand 

 though not yet in type. Subscribers will be quite ready to re- 

 spond to the suggestion of the editor-in-chief, that the delay 

 should be pardoned in view of the fact that the board of workers 

 labor without pecuniary return. 



7. A Manual of the Geology of India. Part IV: Minercdogy 

 (mainly non-economic), by F. R. Mallet. 179 pp. 8vo, with 4 

 plates. Calcutta and London, (Triibner & Co.) 1887. — The 

 economic side of the mineralogy of India has already been dis- 

 cussed in Part III of this work by Mr. V. Ball. The scientific 

 treatment of the same subject has now been taken up by Mr. 

 F. R. Mallet, and this important contribution to mineralogical 

 literature is the result. It is a subject about which our knowledge 

 has been in the past vague and scanty, and although much re- 

 mains to be done in the way of investigating the mineral treasures 

 of India, this complete and accurate presentation of what is now 

 known about them is of great value. 



8. Brief notes on recently described minerals. — Arseniopleite. 

 — Occurs in reddish brown cleavable masses forming small veins 

 or nodules with rhodonite and hausmannite in a crystalline lime- 

 stone from the Sjo mine, Gryhyttan, Sweden. It is shown 

 optically (Bertrand) to be uniaxial and negative, probably rhom- 

 bohedral. Analysis gave:

44-98 tr. 28-25 3-68 4-48 8-11 3-10 5-67 tr. = 98-27 



This is corrected to give Mn 2 3 7 -80, Mn0 2 21-25, H 2 4-54, final 

 sum 97-94. It is closely related to the large group of manganese 

 arseniates from Sweden. — I. J. Igelstrom in Bidl. Soc. Min., vol. 

 xi, 39, 1888. 



Barkevikite, Calciothorite, Melanocerite, Nordenskiold- 

 ltste, Rosenbuschite. — In a preliminary paper giving an outline 

 of results obtained in a study of the augite- and elaeolite-syenite 

 veins of southern Norway, Brogger has briefly described several 

 new species and given new facts about many others, as lavenite, 

 gibbsite, homilite, natrolite, leucophanite, meliphanite, etc.
