The favourable manner in which the first editions of these little 

 works have been received, and the rapidity with which large impres- 

 sions have been exhausted, together with the increasing demand for 

 simple and concise treatises on many other branches of science and art, 

 has induced the .Proprietors to extend the series, so as to embrace the 

 most popular branches of Natural Philosophy. Further numbers are 

 now in progress, and will shortly be published.
