Geo!. Survey, Bulletin 89. Washington, 1898. — In this paper are 

 described a series of superimposed flows, associated with the 

 Neocene andesite tuff, of the western slope of the Sierra Nevada, 

 situated along the course of the Stanislaus River, which are said 

 to stand chemically between typical andesites and typical tra- 

 chytes and for convenience are called "latite" by the author to 

 distinguish them from the ordinary clastic andesites abundant in 

 the same fold. See this Journal, v, 355. n. s. w. 



6. Bibliography and Index of North American Geology, P<de- 

 ontology, Petrology and Mineralogy for 1806 ; by P. B. Weeks; 

 pp. 1-152, U. S. Geol. Survey Bulletin, 149. Washington, 1898. — 

 A valuable feature of these Bibliographies, which are annually 

 prepared by the Survey, is the classified index which enables the 

 student to find at a glance the new matter of any particular kind 

 distributed in the numerous publications of the year. e. s. w. 



7. Report on the Geology of /Southwest Nova Scotia, etc. ; by 

 L. W. Bailey. Geol. Survey of Canada, Ann. Rept., vol. ix, 

 Part M, pp. 1-154, plates i-v, and colored geological map of the 

 region. Ottawa, 189S. — This report embraces the results of sev- 

 eral years investigations by the author in the western counties 

 (Annapolis, Queens, Digby, Yarmouth and Shelburne) of Nova 

 Scotia. 



The formations are the (1) Central granite axis. 



(2) Quartzite and slates like the gold-bearing rocks of Halifax, 

 without fossils but believed to be of Cambrian age. 



(3) Micaceous, hornblendic and staurolitic strata, supposed to 

 be metamorphic equivalents of Cambrian rocks. 



(4) Fossiliferous slates and iron ores, of Oriskany or Eo- 

 Devonian age. 



(5) Red sandstones of Post-Carboniferous age, and believed to 

 be of Triassic age. 



And (6) Trap associated with No. 5. 



The Silurian and Devonian rocks of the Nictaux-Torbrook 

 basin and of Clementsport and the Bear River basin are fully 

 described, and additions, of both fossil localities and species, are 

 made to what has already been reported by Sir William Dawson 

 and others regarding these eastern Paleozoic faunas. Particulars 

 are given regarding the present state of development of the gold 

 districts of Queens aad Yarmouth Counties. h. s. w. 



8. Report on a traverse of the northern part of the Labrador 

 Peninsula from Richmond Gulf to JJngava Bay ; by A. P. Low. 

 Geol. Surv. of Canada, Ann. R^pt , vol. ix, Part L, pp. 1-43,. 

 plates i-iv. Ottawa, 1898. — This reconnaissance survey is valuable 

 in revealing the geographical as w T ell as the geological features of 

 this little known region. The rocks are chiefly ancient crystal- 

 lines, metamorphic schists, eruptives, and stratified dolomites and 

 arkoses, reported as of Cambrian age. • h. s. w.
