small room it may be pleasing, offers poor exhibition space at the angle of the 

 case, and for reasons of construction and general use is injudicious. Figure 57 

 shows such a wall case covering the angle between two walls in the Crane 

 Museum at Pittsfield. 



The flat or table case is the indispensable adjunct of museum installation. 

 It comprises the various designs of cases intended for floor use where smaller or 

 flat objects are exhibited, and it meets the wide range of needs in libraries, art 

 museums and schools, where groups, figure pieces and tall and upright objects 

 are less frequently seen. 



There are two sorts of table case, the desk, single or double, and the inverted 

 V (or A) case on legs. Desk cases of great beauty have been prepared in num-

bers, in the New York Museum, and it would be difficult to suggest anything 

 more propitious for its objects than these (Fig. 58). They are made usually with 

 three sashes, giving them a length of some eighteen feet, and have two sloping 

 sides — one inch in seven — the double desk. They are fitted with green plush 

 on the bearings of the lids, as a dust prevention. Some of these cases are a 

 trifle broad, and the objects at the back of the case are indifferently seen. The 

 best dimensions, using the lettering in Fig. 5!>, are as follows : a-b, 5 ft.; b-c, 

 8 in.; d-e, 12 ft.; d-f, '1^2. ft.; f-g, 3 ft. 2 in.; g-h, 4 ft. 4 in.; g-a, 2 ft. 5 in. 

 Details of construction are given in Fig. t)0, for which I am indebted to Mr. A. R. 

 Strader.
