The Constitution of Canada. By W. R. Riddell. (H. Milford.

5s. 8d. net.)—In four lectures delivered at Yale, and now reprinted with copious notes, Mr. Justice Riddell, of the Ontario Supreme Court, gives a lucid account of the Constitution of the Dominion, and compares it in a most instructive way with the Constitution of the United States. Tho lecture on " The Constitution in its Actual Working " derives special value from the author's judicial experi- ence. In regard to differences between the Provincial Legislatures and the Ottawa Parliament, he states that " for several years tho practice has been settled for the Dominion not to interfere except where the legislation is plainly ultra tires the Provincial Parliament."
