THE POPULAR SCIENCE MONTHLY. 



ors, and made Mr. Bessemer possible, has 

 contributed a large part toward making the 

 world what it is. That it is not perfect, 

 and has from time to time to be supple- 

 mented to meet the constantly developing 

 wants of society, does not detract from its 

 real value, or from the fact that whatever 

 is brought in in addition to it is closely con- 

 nected with it, and largely dependent upon 

 it for the power to perfect itself. It was 

 supplemented in the middle ages by some- 

 thing very like the manual training-schools, 

 in the shape of the guilds, and the systems 

 of apprenticeship and journeymen ; and it 

 is the workmen, who have deliberately cast 

 these systems away, and are decrying all 

 distinctions founded on excellence, and not 

 the advocates of the old education, that 

 have made the new training-schools neces- 

 sary. 



Contributions to the Tertiary Geology 

 and Paleontology of the United 

 States. By Angelo Heilprin, Profess- 

 or of Invertebrate Paleontology at the 

 Academy of Natural Sciences of Phila- 

 delphia. Philadelphia : Published by the 

 Author. 1884. Pp. 117. 



Professor Heilprin has, in the present 

 volume, made a valuable addition to the 

 literature on this subject. 



Besides offering a general systematic 

 review and analysis of the formation taken 

 as a whole, a concise statement is given of 

 the geology of the tertiary period in all of 

 those States of the Atlantic and Gulf bor- 

 der where the formation has been deter- 

 mined; each of these States is separately 

 considered. 



The second division of the book treats 

 of the relative ages and classification of the 

 post-eocene tertiary deposits of the Atlan- 

 tic slope ; and contains carefully prepared 

 faunal lists of Maryland, Virginia, and 

 North and South Carolina. 



The other divisions of the volume re- 

 late respectively to the stratigraphical evi- 

 dence afforded by the tertiary fossils of the 

 peninsula of Maryland ; to the occurrence 

 of nummulitic deposits in Florida, and the 

 association of nummulites with a fresh- 

 water fauna ; a comparison of the tertiary 

 mollusca of the Southeastern United States 

 and Western Europe in relation to the de- 

 termination of identical forms , and to the 



age of the Tejon rocks of California, and 

 the occurrence of ammonitic remains in 

 tertiary deposits. A map accompanies the 

 volume. 



The whole work bears the mark of care- 

 ful study and research, and will undoubted- 

 ly greatly assist the labor of future workers 

 in this field. 



Annual Address. By C. Y. Riley, as 

 President of the Entomological Society 

 of Washington for 1884. Pp. 10. 



The society had just closed its first year 

 when this address was delivered (March 18, 

 1885). The address notices some of the 

 more striking entomological events of the 

 year, and brings forward some general 

 observations that are suggestive. With 

 reference to the Entomological Division 

 of the Agricultural Department, of which 

 Dr. Riley is the head, no one more fully 

 than himself appreciates how far it falls 

 short of his own ideal and of the necessi- 

 ties of the country, or " how difficult it is 

 to build up to that ideal under the unfortu- 

 nate political unscientific atmosphere that 

 pervades the department. ... It was to get 

 away from official surroundings, away from 

 the work of the United States entomologist, 

 that the members of the division decided to 

 join in the organization of this society. It 

 was still more to get acquainted with those 

 of kindred tastes outside the department, 

 in Baltimore and elsewhere, as well as in 

 Washington, and to cultivate social inter- 

 course and interchange of views and expe- 

 rience." The various branches of the sci- 

 ence are well represented in the society and 

 in the various collections in Washington. 



The Climatic Treatment of Disease : West- 

 ern North Carolina as a Health Re- 

 soRt. By Henry 0. Marcy. Pp. 24. 



The former subject mentioned in the 

 title is considered in the first fourteen pages 

 of this pamphlet. Concerning the second 

 subject, we have a description of the tri- 

 angular region between the Blue Ridge and 

 the Smoky Mountains of Northern North 

 Carolina, where, within an area of fifty 

 miles, there are twenty peaks over six 

 thousand feet high ; nine tenths of the en- 

 tire district is an unbroken, primeval for- 

 est of the largest growth, chiefly of decidu-
