THE articles contained in this volume originated with a suggestiotl 

 made by the Rev. Robert Murray, Editor of the " Presbyterian 

 Witness." It was expected at first, that the series would be confined 

 to subjects in Provincial Geology. As we" proceeded our scope 

 expanded and developed, from Local to General. It became world- 

 wide and led to the consideration of subjects of general and deepest 

 interest. Our series commenced in the " P. W."of December 25, 1885, 

 continued weekly in 1886, and ended in February 19, 1887. They are 

 therefore 61 in number. The author has been solicited to publish 

 them in a volume. 



We are urider great obligations to Mr. Murray for the interest he 

 has taken in our articles, and the assistance given in the correction 

 of the Press. Notes have been added and a Synoptical Table.
