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

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.

 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.
