is clipped at the corners by two jaws, working in slots (as in 

 Cox's and other forms), and is thus accurately centered. One of 

 these jaws is fixed and the other attached underneath to the sleeve of 

 the table by a spiral spring and drawn back upon the slide. Provision 

 is made for re-touching slides the circles upon which are not truly 

 central by two brass clips traversing oblique slots cut in the table, 

 and being held in by brass split springs. Several cells can also be 

 placed upon one glass slip. 



A new form of hand-rest, sliding along two grooves cut in the 



Fig. 57, 



sides of the box, can be conven iently adjusted for every class of work. 

 Underneath this rest, and at the opposite end of the box, is a sliding 

 lid, which when drawn back opens a compartment sufficiently large to 

 contain the key, brass clips, small bottles, brushes, rings, cover- 

 glasses, slips, &c.

 [The object is to avoid the formation of two distinct collections, the dissec- 

 tion on the ordinary slide being kept in one place and the insect in 

 another. The author, therefore, uses very fine cardboard in pieces 9 lines 

 by 6. A hole 2| to 3 lines across is punched at one end in the centre and 

 \\ to 2 lines from the edge. The lower side is closed by a cover-glass, 

 and the object mounted in balsam. The dissection can now be placed 

 alongside the insect in the collection. The author also explains his 

 method of preserving larvae by the roasting process, also Aphidse.]
