THE SDPPRESSION OF CONSUMPTION. 



By Godfrey W. Hambleton, M.D. \%^. 40c. 



"The inestimable importance of the subject, the 

 eminence of the author and the novelty of his work 

 all combine to render the little treatise worthy of 

 special consideration. , . . We heartily com- 

 mend Dr. Hambleton's booklet and wish there were 

 more such works."— Editorial, Boston Daily Adver- 

 tiser. 



" The monograph is interesting in style, scholarly, 

 and well worth of careful consideration. It is de- 

 void of technical expressions, and can be easily read 

 and di^Qste^..^^— Pharmaceutical Era. 



'■It IS full of facts and •vfiB^om.y— Philadelphia 

 Saturday Evening Post. 



"The book contains much of importance to the 

 medical fraternity, as well as the general populace.*" 

 —Burlington Hawkeye. 



"We commend the book to physicians and lay- 

 men.^*' — Berold (German), Milwaukee. 



THE SOCIETY AND THE "FAD." 



By Appleton Morgan, Esq*: 12*. 30 cents. 



" Mr. Morgan founds a sensible and interesting 

 address upon a text furnished by a sentence from a 

 young ladies' magazine ; namely, ' Browning and 

 Ibsen are the only really dramatic authors of their 

 century.'"— iVew York Sun. 



" In the little book before us the treatment of the 

 subject is dispassionate and logical. The compari- 

 son drawn throughout this monograph is between 

 Shakspeare and Browning, the subject-matter being 

 largely based on the Browning and Shakspeariun 

 societies and how they came to exist. A pleasant 

 half-hour or more may be spent over the book, and 

 some useful information derived from it."— E'ng^e- 

 wood Ti77ies. 



"To say nothing of the dissection of Browning, 

 the vivid side-lights thrown upon Shakspeare's life 

 and work make the reading of this volume at once a 

 pleasure and a source of instruction." — C/iicaf/o 

 Evening Journal. 



PROTOPLASM AND LIFE. 



By C. F, Cox. 12*. 75 cents. 



The author of this book was for some years presi- 

 dent of the New York Microscopical Society, and in 

 this volume he sets forth his views on the spontane- 

 ous generation theory and its relation to the general 

 theory of evolution, and on protoplasm and the cell 

 doctrme.

THE CHEROKEES IN PRE-COLUMBIAN TIMES 



By Cteus Thomas. 13°. $1. 



Dr. Thomas in this work will reverse the usual 

 method of dealing with prehistoric subjects ; that is 

 to say, he will commence with the earliest recorded 

 history of the tribe as a basis, and trace the chain 

 back step by step by the light of the mounds, tradi 

 tions, and other evidence, as far as possible. He 

 has already presented to the public some reasons 

 for believing the Cherokees were mound-builders, 

 but additional evidence bearing on the subject has 

 been obtained. A more careful study of the Dela- 

 ware tradition respecting the Tallegwi satisfies him 

 that we have in the Bark Record (Walam Olum) 

 itself proof that they were Cherokees. He thinks 

 the mounds enable us to trace back their line of 

 migration even'beyond their residence in Ohio to 

 the western bank of the Mississippi. The object is 

 therefore threefold: 1. An illustration of the re- 

 verse method of dealing with prehistoric subjects ; 

 2. Incidental proof that some of the Indians were 

 mound-builders ; 3. A study of a single tribe in the 

 light of the mound testimony. This work will be an 

 important contribution to the literature of the Co- 

 lumbian discovery which will doubtless appear 

 during the coming two years.

THE TORNADO. 



By H. A. Hazen. 12°. $1. 

 Professor Hazen is one of the prominent meteor- 

 ologists connected with the United States Signal 

 Office. In this work he reviews our present infor- 

 mation as to tornadoes, severely criticising some of 

 the opinions held in regard to them up to this time. 

 No one has given a more careful study to these de- 

 structive storms than has Professor Hazen, and his 

 book will prove a decided contribution to the 

 world's knowledge. In this book will be found a 

 careful discussion of the important question of 

 Tornado Insurance now attracting so much atten- 

 tion. Hundreds of dollars may be saved by people 

 who are thinking of such insurance by following the 

 principles here made plain.
