SCIENCE.

and enforce the special doctrines of the author. Some of them 

 are directed against philosophical agnosticism, a doctrine for 

 which we have as little rpspect as Dr. Carus has; another shows 

 the folly of the antagonism between laborers and their employers ; 

 while still another, which we cannot regard as very successful, 

 illustrates the author's disapproval of utilitarian ethics. The 

 best of them all are those in which some distinctly moral lesson 

 is drawn, especially "The Chief's Daughter," which tells how a 

 certain tribe of savages were led to abandon the custom of human 

 sacrifices, while at the same time it shows the moral superiority 

 of the spirit of man over the blind forces of nature. We do not 

 agree with all of Dr. Carus's views, but we are always pleased 

 with the moral earnestness and the desire to be useful which 

 characterize all his works. 



— Students of American geology and paleontology are well 

 aware of the importance of the Memoirs of T. A. Conrad on the 

 Tertiary Fossils of the United States. These memoirs are prac- 

 tically out of the market, very few copies exist even in private 

 libraries; while few of the fossils figured in them are figured 

 elsewhere. Mr. Gilbert D. Harris, at the Smithsonian Institu- 

 tion, is projecting a reprint of the Eocene or earlier volume, and it 

 has been thought that the more extensive and later Miocene 

 monograph might appropriately be issued by the Wagner Free 

 Institute of Science, Philadelphia, provided a sufficient number 

 of subscriptions shall be received to measurably cover the ex- 

 pense. It is proposed to reprint the text of the " Medial Ter- 

 tiary '' (about 100 pages) verbatim ; to reproduce the original 

 plates by a process of photo-engraving, and to insert a brief in- 

 troductory chapter and a table showing the present state of the 

 nomenclature of the species contained in the work ; the whole 

 forming a volume in octavo of about 150 pages with 49 plates. 

 It is obvious that all libraries of reference and students of geology 

 and paleontology will find the work indispensable; and it is hoped 

 that the response will be such as to render it practicable to under- 



take the reprint without delay. Professor Wm. H. Dall, Paleon- 

 tologist to the U. S. Geological Survey, has consented to super- 

 vise the reprinting, with the collaboration of Mr. Gilbert D. 

 Harris, and to supply an introduction. If subscriptions can be 

 obtained for 150 copies, at |3.50 each, including postage, the 

 work will be undertaken, although that amount will not repay 

 the expense of the publication. Subscriptions may be addressed 

 to the Wagner Free Institute of Science, Philadelphia, Pa. 



— Charles L. Webster & Co. have published a new work by 

 Henry George, in which he criticises Herbert Spencer's utter- 

 ances on the land question. It is entitled " A Perplexed Philoso- 

 pher," and assails Mr. Spencer for having changed his views 

 without adequate reason. In his work on Social Statics, which 

 he wrote in early manhood, Mr. Spencer maintained essentially 

 the same theory about property in land that Mr. George holds 

 now ; but in his later writings he has repudiated that theory, 

 and now advocates the system of individual property in land as 

 in everything else. Mr. George is able to show that some of his 

 opponent's reasons for his change of view are not conclusive; 

 but he goes much further and charges him with intellectual dis- 

 honesty and with the desire to curry favor with the British aris- 

 tocracy. We don't believe, however, that Mr. George's charges 

 will find acceptance except with the fanatical advocates of his 

 own doctrines; for Mr. Spencer's change of view admits of a 

 much more reasonable explanation. He has been for many years 

 the staunchest upholder of individualism in all its forms and a 

 violent opponent of socialism and of all efforts to extend the in- 

 fluence of the State; and it is obvious that the advocate of such 

 doctrines could not long continue to favor the communal owner- 

 ship of land. Mr. George's criticisms are incisive, and, as we 

 have remarked, some of them are well taken; but we doubt if 

 his book will change any man's views on the question in contro- 

 versy, or help in the least to make his own doctrines more accept- 

 able. 



Uffspepsia 



' Dr. T. H. Andrews, Jefferson

Horsford's Acid Phosphate. 



"A wonderful remedy which gave me 

 most gratifying results in the worst 

 forms of dyspepsia." 



It reaches various forms of 

 Dyspepsia that no othei medi-

 the weakened stomach, and 

 making the process of diges-
