CHEAP BOOKS PUBLISHED BY GRIGG & ELLIOT. 



SMILEY'S ARITHMETIC, or the New Federal Calculator, in dollars 

 and cents. This work contains, among other important improvements, 

 Questions on the Rules and Theory of Arithmetic, which are considered by 

 teachers generally, very conducive to the improvement of the pupil. 



Although a prejudice exists among some teachers in favour of the old works on 

 arithmetic, yet the very liberal patronage which this work has received, must be 

 considered as decisive evidence of the great estimation in which it is held by most 

 of the instructors of youth. Upwards of 250,000 copies have been printed' and 

 sold. The s*ums being altogether in dollars and cents, gives it a decided preference 

 over any other arithmetic in use. The most distinguished teachers of pur city 

 pronounce it superior to any other like work ; therefore the publisher sincerely 

 hopes this useful improvement will overcome the prejudice that many teachers 

 have to introducing new works, particularly those preceptors who wish to discharge 

 their duty faithfully to parent and child. 



The editors of the New York Telegraph, speaking of Smiley's Arithmetic, 

 observe, " We do not hesitate to pronounce it an improvement upon every work 

 of that kind previously before the public, and as such recommend its adoption in 

 all our schools and academies.' '

The eminent Professor Bigelow, of Harvard University, in noticing this work, 

 observes, " I am satisfied that it contains the fundamental principles and truths of 

 that science, expressed in a clear, intelligible, and interesting manner. The high 

 character of the author, as a lecturer, and a man of science, will, I doubt not,
