The new hall measures 44 feet by 34 feet. A gallery 15 feet from 

 the ground is supported by iron pillars which reach upwards to the 

 roof. The whole middle part of the roof is of glass, and its curved 

 sides over the gallery are beautifully arched and moulded, the corner 

 alcoves being a chief triumph of the architect's skill. 



The front of the gallery is handsomely constructed of pitch-pine, 

 carved and panelled. The general colour of the interior is cream,

relieved with gold, and the interior of the cases is painted a pale 

 greyish blue. The wall-space above the wall-cases and below the 

 gallery is occupied by geological diagrams of sections across the 

 county, from designs by Mr. Henry Coates. These sections show 

 four representative traverses across different parts of the county ; 

 they are drawn to scale, and the colouring is that of the Geological 

 Survey sheets. 



The sketch (Fig. 2) shows the ground-plan of the floor of the 

 Museum. The range of wall-cases AAA extends round the four 

 walls. These cases are 7 feet 6 inches high, with a 9-inch base-board.
