To those men of science who, in this matter and in the work of 

 the general Committee and Sub-Committees, have given much 

 valuable time, and have afforded them the benefit of their great

 . on Education feel their best-thanks are due, and they trust that 

 the immediate success and future results of the Exhibition, which 

 owes so much to them, will reward them for the labours which 

 they have ungrudgingly devoted to it. 



In order to make the Exhibition as useful and interesting as 

 possible, a handbook containing introductory notices to the 

 several sections has been prepared. For writing these notices the 

 Lords of the Committee of Council on Education have * been
