The permanent museum equipment has been increased as 
follows: 
(a) Exhibition blocks. A few blocks of special sizes were 
secured during the year, while many blocks of the standard 
sizes from the supply secured last year were prepared and 
placed in the cases as they were needed. 
(6) Glass jars. (Specimen-jar, 2605, Whitall Tatum Co.) 
Diameter. Height. Number of jars. 
2 inches. 5 inches.

(c) Oak frames, for displaying specimens mounted on 
cardboard, and plates and photographs. Frames of the 
standard sizes amounting to a total of 1,081 were added to 
the museum equipment. This addition nearly completes the 
present requirements of the systematic museum. 
3. Economic Museum. The amount of case-space added 
to that previously occupied by the economic collections 
amounts to about one hundred per cent., and about two 
thirds of the available space for cases on this floor is now 
occupied. 
The standard cases are now grouped in rectangular blocks 
of four or six units. In the main east and west halls the 
blocks are composed of six units, while in the wings they are 
composed of four. 
The specimens contained in the original equipment of 
cases have been spread out into the new cases and a large 
number of others, hitherto necessarily stored in the basement, 
have been interpolated; these are being permanently ar- 
ranged as rapidly as the labels can be struck off by our 
printing outfit. Foods and fibers occupy the west hall; the 
former in cases on the north side, the latter on the south.
