��rally devotes his attention chiefly to the ef- fects of our tariff on our foreign commerce and our carrying-trade, the aspects of the subject with which his experience has made him most familiar. The author maintains that what prosperity we have in this coun- try is obtained from our natural resources and in spite of the protective tariff rather than because of it ; that the country is not so prosperous but that we have among us con- stantly a vast army of workers without work ; and that the tariff closes to our prod- ucts the foreign market, in which we might make large sales. The restrictive system has almost destroyed American shipping, and ship-owners are now looking for contri- butions from their fellow - citizens in the form of subsidies to enable them to carry on this unprofitable industry. The mill- owners get such contributions, and the ship- owners ask, Why should not we ? The farm- ers, who number about half our working population, and are more than four times as many as the manufacturing workers, suffer severely from a system which protects their products about twenty per cent and taxes them on their purchases nearly seventy per cent. The author's positions are fortified by numerous pertinent facts and figures.
Eating fou Strength. By M. L. IIoLBnooK, M. D. New York : M. L. Holbrook & Co. Pp. 23C. Price, §1,25.
This book is a popular general guide on the subject of diet, not limited to the case of the athlete, as might be inferred from its title. Its language is simple, and, though scientific reasons are given for its directions, the volume contains nothing that the general reader can not understand. The first hun- dred pages arc devoted mainly to telling the nature and value of the various classes of food-substances which we use, much of the information being arranged in the form of instructive tables. A plea for simplicity in living follows, enforced by the experience of persons who have lived for years wholly or mainly on fruit and vegetables. In the next chapter, the composition and value of each of the chief foods of the vegetable kingdom is set forth, the section on grapes including an account of the grape-cure. Some sug- gestions follow concerning diet for different ages, circumstances, and a number of speci-
��fied diseases. The volume contains also sev- eral hundred recipes for wholesome foods and drinks, comprising soups, bread, eggs, vegetables, puddings, cake, and even pics, which the author says are wholesome or not as they are well or badly made ; also the preparation of tea, coffee, etc., with cautions as to their use, and a variety of beverages from fruit-juices, milk, etc.
The Peter Pvedpath Museum of McGill University has issued a pamphlet on speci- mens of Eozoon Ccmaden.se and their Geo- logical and other Relations, by Sir J. William Dawson, F. R. S. (Dawson, Montreal, 50 cents), the purpose of which is stated in these opening lines. "Whatever may be the ultimate decision of palasontologists as to the nature of Eozoon, it is important that the original specimens on which its descrip- tion was based, and those later acquisitions which have thrown further lij;ht on its struct- ure and have been published in that connec- tion, should be preserved and catalogued. The collections made by Sir W. E. Logan arc now for the most part in the Museum of the Geological Survey at Ottawa, Those accumulated by the author of these notes, as well as duplicates preserved by Sir \V. E, Logan, are in the Peter Eedpath Museum. It is to these latter collections that the pres- ent paper relates, and the object is to render them as useful as possible for scientific pur- poses in the future." The pamphlet is not a catalogue, though it contains a synopsis of the specimens to which it relates, but has the form of a monograph, the divisions of which are, geological relations, state of pres- ervation, new facts and special points, notes on peculiar specimens, replies to Mobius, Ilahn, etc., paleozoic fossils mineralized with silicates, phosphates, and graphite of the Laurentian, and a summary of argu- ments in support of the animal nature of eozoon. A bibliography of the subject oc- cupies six pages, and sixteen cuts illustrate the text.
Parts II and III of Vol. II of The Jour- nal of the ColUrjc of Science, Imperial Uni- versity, Tokio, Japan, have been received. Part II comprises three papers : " On the so-called Crystalline Schists of Chichibu," by Prof. Bundjiro Koto, Ph. D. ; " On the Plants of Sulphur Island," by Prof. Samuro
