blocks and to be installed in a group of which the single type L 

 case forms a center. The exhibition space is in the form of a 

 truncated wedge of which the base is 8 feet long by 3 feet wide 

 and is raised 3 feet above the floor level. 



Type K. Type K cases differ from type I only in size and pro- 

 portions. They are intended for the display of the larger slabs of 

 fossil remains which, on account of their development of fine 

 detail, need to be closer to the eye of the observer than would be 

 possible in a deck as close to the floor level as that of type I. The 

 rectangular exhibition space which measures 4 feet long by 2 feet 

 6 inches wide by 2 feet 6 inches high, is consequently raised to a 

 level of 3 feet from the floor level. For the interior furnishing of 

 these cases narrow, high diaphragms or step-blocks are best adapted

 exhibited and from that of the proportions of the exhibition space. 

 Type L. Unlike the preceding types, this case design, of which 

 only one was installed, was made to accommodate one particular 

 specimen, a large crystal of calcite installed in the Mineralogy 

 Hall. The exhibition space is rectangular, measures 4 feet 6 inches 

 square by 2 feet high, and is raised 2 feet 6 inches above the floor 

 level.
