The Century Dictionary. 
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 re _ to be at once full and 
accurate, THE CENTURY DICTIONARY is above every o 
tis not only a complete word Dictionary, but it is an aevel 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 a 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. Seymour, 
Lester F. wots Sereno Watson, and J. D. Whitney over various other departments 
of Natural History. 
The astrations (about 8000 in number) have been prepared by the art depart- 
ment of The Century Magazine. Their superiority over the ordinary dictionary 
“cuts” is elan 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 appearance 
so earnest has been the endeavor to bring the work up to date) will be completed in 
six volumes of about 1200 pages each. 
The Dictionary is sold only hy Subscription. 
Subscribers may take and pay for 
the four volumes now ready at once, or they 
y be delivered and paid for at con- 
venient intervals, as preferred. Whether one his to purchase or not, it will pay 
to send five two-cent stamps to hol publishers for the handsomely illustrated pam- 
phlet of specimen pages, containing also a complete description of the work, list of 
contributors, etc. It is SEES in itself. Address,
