APPLIED MECHANICS. 



As the Exhibition must be regarded as chiefly referring to education, 

 research, and other scientific purposes, it must in this division consist principally 

 of models, diagrams, mechanical drawings, and small machines, illustrative of 

 the principles and progress of mechanical science, and of the application of 

 mechanics to the arts. 



Properties of Materials. 

 Structures at rest and in motion. 

 Prime movers. 

 Reservoirs of energy. 

 Regulators. 



The application of the principles of 

 mechanics to machinery as used in 

 the arts. 



Shipping, naval architecture, and 

 marine engineering. 



CHEMISTRY. 



Scientific instruments, apparatus, and materials employed in the investiga- 

 tion and teaching of chemical science, and in the application of its principles to 

 scientific purposes. 



Diagrams and models. 



Illustrations of analytical results. 



Specimens of chemicals, (a), organic, 

 (b) mineral. 



Apparatus and fittings for laboratory 

 and lectures. 



Apparatus for gravimetric and volu- 

 metric operations. 



Apparatus for distillation and filtra- 

 tion. 



Apparatus for operations by the dry 

 or hot method, such as furnace, 

 blowpipe, &c. 



Refrigeratory apparatus. 



Apparatus for spectrum analysis. 



NOTE. Operations of the following nature may be illustrated, viz. :-
