w. WTJNDT'S LOGIK, n. 451 federal legislature nor the legislatures of the federated states can be allowed unlimited powers if the federation is to be a reality. The two or three pages on the early history of Contract are not only too vague and slight in themselves, mixing up fact and hypothesis, as the farmer's daughter jumped over tables and chairs, " with apparent ease," but they might well mislead students by letting them suppose that an exceedingly difficult subject is an easy or an exhausted one. Now, if we cannot trust Mr. Miller in the Constitution of the United States or the history of Roman Con- tracts, which we have seen, how shall we trust him in things in general which we have not seen '? The book is, to its credit, well indexed. And there is a classfied bibliographical appendix of which the general idea is meritorious. But in execution it is too little for completeness and too much for a select list. Oddly enough, Mr. Justice Stephen figures among the historical school. He ought to go with Hobbes and the utilitarians, of whom he is the legitimate and uncompromising successor : in dealing with the Criminal Law he nas been his- torical perforce, not of freewill. Small matters these may be in themselves : but we profess a science and art which are nothing if not critical. Philosophy is well, but exactness in one's own business is first. If I may add one word of counsel to those who seek to gather treasure abroad for the philosophical study of law, I would say : ' Go not after Hegel, nor any other philosopher who explains law because he must explain everything ; but seek after the philo- sophical jurists who know law first, Savigny, Bluntschli, Holt- zendorff, Ihering, Holmes : and you shall find your reward '.

Pp. xiii., 620. This work is the supplementary volume on the subject of j general Logic to one which appeared four years ago (reviewed in MlND XIX.). As the names Erk*nntni*d>-hr'> and M^tttodenlehrt imply, the earlier volume dealt rather with the formal and
- abstract aspect of Reasoning, whilst the latter is devoted to a
- somewhat detailed examination of the principles, methods, and
results of the special sciences. It is an astonishing product of ability and industry. No important branch of science, whether physical or mental, is passed over without a careful examination, extending from its earliest history to its very latest developments ; and the knowledge thus displayed is at least within any power i which the writer of the present notice has to judge as accurate as it is extensive. The only English works which will give the
