Geology. Bailey, Prof. L. W., M.A., Ph. D., F.R.S.C " Pre- 

 liminary Report on Geological investigations in south-western Nova 

 Scotia" Being Report Q. of Vol. VI., Annual Report, Geological 

 Survey of Canada, 1892-93, published 1895, 21 pp. 

 Pending the publication of Dr. Bailey's final report addressed to the 

 Director of the Geological Survey of Canada, the preliminary report here 

 referred to has been published and forms part of the 6th Annual Report of 

 the Geological Survey. The delineation of the granite areas in South- 

 Western Nova Scotia, the South and Blue Mountains, Tusket Wedge, the 

 Barrington area, the Shelbourne and Port Mouton areas are given and 

 the reader is referred to Sir Archibald Geikie's descriptions of South- 

 Eastern Ireland as applying, almost word for word, to the granites of 

 South-Westem Nova Scotia. The Cambrian Succession, as seen 

 in Queen's Co., is carefully described and the possible existence J pre- 

 Cambrian rocks pointed out. As to the Devonian System our 

 knowledge was still incomplete. On pp. 14 and 15, a brief summary of 

 the palceontological results obtained by Dr. Ami after examining the col- 

 lections in the Peter Redpath Museum and in the possesion of the 

 C.eological Survey is given. Most of the collections from Nictau point 

 to Eo-Devonian time. The Triassic and Post-Tertiary s)stem 

 are next crscussed, and the economic minerals receive considerable 

 attention.

 can Geologist" Vol. XV., No. 3, pp. 146-153, March, 1895. 

 In this paper the author reviews Mr. L. Cayeux's paper describing 

 certain so called Pre-Cambrian Radiolaria. No less than 45 different 

 kinds of rhizopods have been described and are figured on one plate. 



Mr. Cayeux's microscopic slides were examined both by Dr. G. J. 

 Hinde, of London, England, and by Dr. Rust, of Hanover, Germany. 

 These two gentlemen, whilst not agreeing with his (Cayeux's) conclu- 

 sions, admitted that the forms were organic."
