APPENDIX I. 



similar box with a wooden rabbet is used at the Museum 

 of Comparative Zoology at Cambridge ; but it cannot 

 possibly be so tight, and requires hooks on the sides to 

 keep the cover down ; it has the advantages of greater 

 cheapness, as it can be made of soft wood, but is at the 

 same time clumsier. My own drawers are made of 

 cherry sides, and have also a false front attached to 

 them, furnished with mouldings and handles so as to 

 present a not inelegant appearance ; and, exclusive of 

 the cork with which they are lined, cost $2.65 each ; 



FIG. 201. Model of the Deyrolle insect-drawer, side view of front end, with 

 the cover raised. D, bottom of drawer ; C, cover of same, raised a little ; /, 

 front piece, with moulding (m) and handle (A), glued to bottom piece ; sa, eash ; 

 si, slit in cover, into which the zinc strip (z) fits ; si', slit in bottom, into which 

 it is fastened ; g, bevelled groove, to allow the finger to raise the cover ; Hv, 

 hind view of one end of the bottom to show the insertion of the bottom (b) ; Be, 

 reverse of one corner of cover to show the grooves filled beyond their junction. 

 All the figures half size. 



they measure inside 18f inches long, 14 inches wide, 

 and If inches deep, not including the cork lining. 



It is best always to cover the bottom of such drawers 

 with cork or pita wood or similar soft substance, as it 

 is difficult both to insert and to withdraw the pins 

 readily in any ordinary wood, however soft ; and the 

 sides and bottom should afterwards be covered with 

 thin white paper for neatness' sake. 



Drawers like these are rather large for small collec- 

 tions, but any smaller size is wasteful of space for 

 arranging the larger species of wide expanse of wing.
