This paper is an historical and descriptive work of the present knowledge of the Cambrian 

 group of rocks of the North American continent. Chapter I gins a statement of the prin- 

 ciples upon which the delineation of the group is made, with a lew brief remarks upon the 

 nomenclature of the formation and a list of the hooks and articles consulted in the prepa-a- 

 tion of the work. The second chapter contains a historical review of the geological and pale- 

 ontological work that has been done in all provinces in which the Cambrian group occurs. 

 Chapter m embraces a record of the names that have been employed to designate the various 

 formations. Chapter iv gives a summary of the present knowledge of the formations in each 

 of the four great geological provinces. A map showing the geographical distribution accom- 

 panies this chapter; also, one on which the sedimentation is illustrated by vertical columns 

 of strata. Chapter v deals with problems for investigation, and Chapter VI is devoted to the 

 study of criteria and principles used by authors in the correlation of the various parts com- 

 posing the Cambrian group.

This is a preliminary description of t lie discovery of a vertebrate fauna in the lower Silurian 

 (Ordovician) strata. It includes a description of the locality and the stratigraphy of the

Defines government as the business agency of the nation, and the science and art of govern- 

 ment as those of conducting this business agency; hence lays stress on the importance of 

 some system of instruction on these subjects as branches of education. Instruction in public 

 administration and all governmental operations should form a prominent department of polit- 

 ical economy teaching.

Troposes a general plan for such an institution so as to make it truly representative in char- 

 acter, the leading chair to be that of political science, with special prominence attached to in- 

 struction in the science and art of government as outlined in the foregoing paper, all officers of 

 the civil service to be ultimately selected from graduates of the national university.
