JONEERS OF SCIENCE IN AMERICA. 
Sketches of their Lives and Scientific Work. Edited and re- 
vised by WILLIAM Jay Youmans, M.D. With Portraits, 
8vo. Cloth, $4.00. 
Impelled solely by an enthusiastic love of Nature, and neither asking 
nor receiving outside aid, these early workers opened the way and initiated 
the movement through which American science has reached its present com- 
manding position. This book gives some account of these men, their early 
struggles, their scientific labors, and, whenever possible, something of their 
personal characteristics. This information. often very difficult to obtain, has 
been collected from a great variety of sources, with the utmost care to secure 
accuracy. It is presented in a series of sketches, some fifty in all, each with 
a single exception accompanied with a well-authenticated portrait. 
“ Fills a place that needed filling, and is likely to be widely read.”"—N. ¥. Sux. 
“It is certainly a useful and co ient vol , and readable too, if we judge cor- 
rectly of the degree of accuracy of the whole by critical examination of those cases 
ia which our own knowledge enables us to form an opinion. . . . Jn general, it seems 
to us that the handy volume is specially to be commended for setting in just historical 
perspective many of the earlier scientists who are neither very generally nor very well 
known.”’—New York Evening Post. 
“ A wonderfully interesting volume. Many a young man will find it fascinating. 
The compilation of the book is a work well done, well worth the doing.” Philadelphia 
Press. 
‘One of the most valuable books which we have received.” —Boston Advertiser. 
“A book of no little educational value. . . . An extremely valuable work of refer- 
ence.’’— Boston Beacon. 
‘A valuable handbook for those whose work runs on these same lines, and is likely 
to prove of lasting interest to those for whom ‘les documents humaia’ are second only 
to history in importance—nay, are a vital part of history.”—Boston Transcript. 
“A di phical history of sci in America, noteworthy for its completeness and 
scope. .. . All of the sketches are excellently prepared and unusually interesting.”’— 
Chicago Record. 
“One of the most valuable contributions to American literature recently made. . . . 
The pleasing style in which these sketches are wntten, the plans taken to secure ac- 
curacy, and the information conveyed, combine to give them great value and interest. 
No better or more inspiring reading could be placed in the hands of an intelligent and 
aspiring young man.” —New Vork Christian Work. 
_ ‘‘ A book whose interest and value are not for to-day or to-morrow, but for indefinite 
time.” —Rochester Herald. 
“It is difficult to imagine a reader of ordinary intelligence who would not be enter- 
tained by the book. . . . Conciseness, exactness, urhanity of tone, and interestingness 
are the four qualities which chiefly impress the reader of these sketches.” —Bxffalo 
Express. 
“Full of interesting and valuable matter.” —The Churchman.
