In fig. 2 the first five compartments are represented as filled to show the intermingled use of boxes and bottles. Compartment the first contains two of the larger bottles and box size 1; the second, six larger bottles; the third, six boxes size 3; the fourth, box size 2, three boxes size 3, box size 2; the fifth, two larger bottles, box size 2, and three smaller bottles.

In arranging the cabinet, the twelve compartments to the left of each drawer are usually filled, and the four compartments on the right left empty for future acquisitions, when the drawer becomes full an empty drawer can be inserted, as has been already described.

The optional use of boxes, trays, tubes, and bottles enables the whole collection to be scientifically arranged, so that any species required is at once found.

The larger bottles from the width of the mouth will afford room for much larger things than might be supposed. Thus to take the Crustacea as an example. They will hold such smaller Brachyura as Pinnotheres, Ebalia, &c., the smaller Pagurida, most of the Macrura, the whole of the Mysidea, Cumacea, Isopoda except of the larger species of Ega; Amphipoda except Euryporcia gryllus; and all the lower Crustacea except the larger species of Pennella and the larger Cirripedia; and one of these cabinets will contain more than four thousand bottles of such Crustacea.

It is advisable once or twice in the year to go through the drawers which contain bottles. Each drawer is taken out and slightly tilted, when any bottle that shows deficiency of spirit is at once detected; the bottle is filled up and, if necessary, a new cork used.
