The Century Diction 
S a reference-book for men who cannot afford a great library, but who need 
some work to which they can refer for a definition of a common word or 
for a scientific or technical term, which can be depended upon to be at once full and 
accurate, THE CENTURY DICTIONARY is above every other. 
It is not only a complete word Dictionary, but it is an encyclopedia of common 
things as well. The large number of scientific and technical words defined and the 
care that has been taken to secure absolute correctness is one of the features of the » 
work, THE CENTURY DICTIONARY has obtained its scientific and technical defini- 
tions at first hand, from men who, as specialists, are practically familiar with the 
words and things defined. Prof. Elliott Coues, M.D., Ph.D., has been in charge of 
the department of General Zoology, Biology, and Comparative Anatomy, with Prof. 
Theodore N. Gill, Edward H. Jenkins, Frank H. Knowlton, Arthur B. Seymouh 
Lester F. Ward, Sereno Watson, and J. D. Whitney over various other departments — 
of Natural History. 
The illustrations (about 8000 in number) have been prepared by the art depart- 
ment of The Century Magazine. Their superiority over the ordinary dictionary 
“cuts” is apparent at a glance. The Dictionary (which was begun ten years ago 
though it is only a little more than a year since the first volume made its appear 
so earnest has been the endeavor to bring the work up to date) will be co 
six volumes of about 1200 pages each. Four of the volumes (from A through P) 7 
are now ready. Volume five will be issued in the spring, and volume six 4 few 
months later 
The Didtiaaey i is sold only by subscription. Subscribers may take and pay for 
the four volumes now ready at once, or they may be delivered and paid for at 
venient intervals, as preferred. ether one wishes to purchase or not, it Be 
to send five two-cent stamps to the publishers for the handsomely illu ae 
phlet of specimen pages, containing also a complete description of the work, list 
contributors, etc. It is interesting in itself. A
