REVIEWS — THE VALIDITY OP CONSCIOUSNESS. 379 



and the Hamilton shales : the latter with their petroleum springs 

 and asphalt deposits. (6 and 7.) The Eastern basin, comprising 

 various formations of the Lower and Upper Silurian series, inclu- 

 ding the Sillery group of conglomerates and graptolitic schists, 

 unknown in "Western Canada. In its geological position this hand 

 is intermediate between the Hudson Elver group and the Medina 

 sandstone. The eastern basin includes also the Devonian and 

 Lower carboniferous beds of Gaspe ; and offers in its lines of 

 disturbance and very generally metamorphosed condition, a remark- 

 able contrast to the Western District. The metamorphic rocks of 

 this division are discussed in detail in chapter 7, one of the most in- 

 teresting in the volume. Chapters 8, 9 and 10, treat respectively of 

 the post-tertiary and alluvial deposits, the mineral springs, and the 

 great basin of the North. It may be remembered, with regard to 

 the latter, that the results of the survey have shewn the absence of 

 Lower Silurian strata apparently along the entire district : and hence 

 the inference of Sir William Logan, that the southern boundary of 

 the Laurentian range, from Labrador to the Arctic Ocean, formed 

 the limiting shore-line of a Lower Silurian sea. 



It was our intention to have presented to the readers of the 

 Journal, a condensed translation of this most useful little work ; 

 bat finding that an English edition, from the pen of Professor Hunt, 

 is shortly to appear, we have confined ourselves, in the present no- 

 tice of the publication, to a simple announcement of its contents. 



The volume concludes with a classified list of the economic mine- 

 rals of Canada, and of their respective special localities : forming a 

 complete index to our mineral wealth. The Geological Commission 

 would confer no common benefit upon the public, by re-issuing at 

 once this latter part of the work, both in Erench and English, and 



causing its general circulation throughout the Province.

We do not intend at present to enter into a formal and complete 

 review of Sir William Hamilton's Philosophy, to which the title of 



• The substance of tin- following review was originally produced in the form of a commu- 

 nication read before the Canadian Institute, 9th February, 1856, under the title of " Brief 

 Notes on certain statements of sir William limn ill on regarding the validity of our primary 

 Beliefs." The date of tbat communication will account for its being written without refe- 

 rence to the death of the distinguished philosopher, some of whose opinions are brought 

 under review.
