The results of the use of these Outlines in the writer's classes at the University of Michigan have been most satisfactory but corrections or suggestions for their improvement will be gladly received from any one interested. The thanks of the writer are due Prof. Benj. F. Bailey, of the University of Michigan, for encouragement in the preparation of these Outlines and for suggestions for their improvement; also to Mr. Walter M. Rennie and to Mr. G. W.
