 ship permanently 011 

 a strip of thick plate 

 glass, which has been 

 prepared previously 

 by being cut to the 

 proper size, and 

 ground on the edges. 

 The accompany- 

 ing cut (Fig. 28) was 

 drawn from a speci- 

 men as exhibited, 

 omitting the label. 

 The advantages of 

 this arrangement are 

 as follows : It shows 

 the specimen per- 

 fectly on both sides ; 

 the wings do not 

 warp and shrivel 

 up ; it is possible to 

 repair breaks in the 

 wing membrane, and 

 the most delicate 

 specimen is well 

 protected. The strip 

 of glass stands on 

 edge in a deep 

 groove which has 

 been cut to fit it 

 tightly in the top of 

 a flat, narrow ped- 

 estal having the us- 

 ual moulded edge.
