posed of all others, that few men possess the almost universal 

 knowledge required to produce a good manual of its elementary 

 principles. The author of this work being a profound geologist 

 mineralogist, zoologist, and physicist, is one of the best qualified 

 for the task. His book is a great one, and its publication will 

 mark the commencement of a new era in the progress of the 

 science. In conclusion we would strongly recommend it to the 

 Canadian student. With the General Report on the Geology of 

 Canada, soon to be published by Sir W. E. Logan, the Decades o^ 

 the Survey, and Dana's Manual, he can enter the field unimpeded 

 by the crowd of difiiculties to which observers in this province, 

 have heretofore found themselves opposed at the very outset.
