"To awaken genius and sharpen competition, premiums of re- 
ward for merit, in number and value unprecedented by any other 
similar institution, have been awarded. Within the last three 
years they have numbered 2,635. To reach the varied occupa- 
tions of industry and art, and to give effect to the premiums, the col- 
lection of exhibited articles is required to be very extensive."

" School of Applied Chemistry.''^ We are in receipt of a cir- 
cular issued from the Analytical Laboratory, Yale College, New- 
Haven, for 1848, in which it is stated that " A regular course of 
lectures will be delivered in the winter of each year, commencing 
in January, and continuing about two months, there being four

indicated for study during leisure hours. 
In connection with the lectures will be a short course of Ele- 
mentary Chemistry, for such as wish to study somewhat more of 
chemistry than is given in the course, and to qualify themselves 
for making ordinary testings and qualitative examinations of soils, 
manures, &c. ; this course will occupy two hours of five days in
