By the attention of its Secretary, we have been favored with a copy 
of the 2nd part of the transactions of the Society of Arts, &c. This 
society is conducted on the most liberal plan, and under its fostering 
care science has advanced in the most encouraging manner. Large 
premiums are annually offered and awarded, according to a list of 
subjects drawn up with great care. All inventions which are elicited 
in this manner, are thrown open for the free use of all, without pa- 
tent, and the halls of the society contain models of all machines and 
contrivances which have ever come under its patronage.
