SCIENCE. 



[Vol. XX. No. 493 



in the United States of cabinet government as known abroad. 

 The next article is by Mrs. S. L. Oberlioltzer, and relates how 

 much good "School Savings Banks" have done and are doing. 

 Professor J. B. Clark of Smith College has a paper on "Patten's 

 Dynamic Economics," in which he explains the latest system of 

 political economy, taking up Professor S. N. Patten's recent book 

 as a basis for his remarks. Professor Leon Walras of Lausanne 

 contributes an article on the " Geometrical Theory of the Distri- 

 bution of Prices,'" in which he presents a geometric picture of the 

 causation of the prices of all commodities Besides these there 

 are articles by Mr. B. F. Hughes on "Basis of Interest," by Leo 

 S. Rowe on the " Conference of the Central Bureau for the Pro- 

 motion of the Welfare of the Laboring Classes," by Takekuma 

 Okacla on "Taxation in Japan," and the usual book-reviews and 

 personal notes. 



— W. H. Lowderwilk & Co., Washington, announce that they 

 have assumed the publication of " Hickcox's Monthly Catalogue 

 of Government Publications,"' which they will complete up to 

 date and issue regularly and promptly in the future. Mr. Hick- 

 cox will edit the catalogue as heretofore, but all rights in the work 

 have been purchased by the publishers. Up to this time the work 

 has been prosecuted under many difficulties, and the pecuniary 

 returns have been very inadequate, by reason of which facts it 

 was not kept up with the regularity which its importance de- 

 manded. It is expected to issue early in July the first six num- 



bers of 1892, under one cover, succeeding numbers to follow eiirly 

 in each month thereafter. As rapidly as the matter can be pre- 

 pared the back volumes will be completed and sent to subscribers. 

 It is not expected that the undertaking will prove a remunerative 

 one, but it is hoped that there will be a return sufficient to repay 

 the actual outlay of money. The work is of the utmost value to 

 every person who has occasion to handle or consult the current 

 publications of the government, and these publications are now 

 so varied and comprehensive that persons interested in any 

 branch of science or business must appreciate it. 



— Under the title of " The Cambridge Natural History,'' Mac- 

 millan & Co. have in active preparation an important series of 

 volumes on the Natural History of Vertebrate and Invertebrate 

 Animals, edited, and for the most jjart written, by Cambridge 

 men. W^bile intended in the first instance for th jse who have not 

 had any special scientific training, the volumes will, as far as pos 

 sible, present the most modern results of scientific research. Thus 

 the anatomical structure of each group, its development, palaeon- 

 tology, and geographical distribution, will be considered in con- 

 junction with its external chai-acter. Care will, however, be 

 taken to avoid technical language as far as possible, and to exclude 

 abstruse details which would lead to confusion rather than to in- 

 struction. The series will be under the general editorship of Mr. 

 J. W. Clark, the university registrar, and Mr. S F. Harmer, 

 superintendent of the Museum of Zoology. The following writers
