 well as the card braces represented in the illustration and 

 permit one better to see whether the wing is lying perfectly

 the wings into the desired position, and " to set " the 

 antennae and legs in a natural attitude; to secure these in 

 the proper place they are supported by insect pins stuck

 they will dry readily but not be exposed to dust. At the 

 expiration of that time they are ready for the cabinet. 



When one is away from home conveniences, a very

 paper (rather thin writing-paper is best) into 

 '^ triangles/' as along the dotted lines in this 

 sketch; into this the butterfly is placed, its 

 wings folded back to back and antennae tucked carefully 

 away. The place, date, and circumstances of capture (or

 For this purpose moistening-pans are needed. A glass or
