SPECIFICATION. 



Height, 40 in. ; width, 46 in. ; thickness, sj in. Two glass doors in mahogany-stained polished wooden 

 frames, on brass hinges, with lock and key, and two flush bolts. Interior fitted with central partition and twelve 

 movable shelves. On the background is the " CHART OF THE ELEMENTS " mounted on mill-board and varnished, 

 and so fixed that, in the event of a subsequent edition being published, the old Chart may in a few minutes be 

 replaced by a new. 



Cabinets, with glass fronts and shelves, in which the Chart is made to form the background, have 

 been introduced to enable the student or experimentalist to extend the system, and to collect Specimens of the 

 Elements. The system of the Cabinet enables every Element to be filed away in its proper section, where it is 

 always at hand for examination or for the determination of its unknown properties. The educational value of the 

 Cabinet will be at once apparent. Since many of the Elements are very rare, and some have never yet been reduced, 

 the filling of the Cabinet with specimens must necessarily be a work of patience on the part of the collector.
