THE POPULAR SCIENCE MONTHLY. 



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,

 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
