of beeswax, or cork. The box should be anointed with 

 spirits of turpentine, to prevent the entrance of destructive 

 living insects. 



III. Butterflies, and all other winged Insects, are to be 

 taken by the aid of a net, or Butterfly-scissors, made ex- 

 pressly for the purpose, and immediately stuck upon 

 pins. Great care is to be taken that no part of the body 

 be injured. 



IV. The most beautiful Butterflies of the different 

 species can be obtained, by collecting, in the months of 

 March and April, or in autumn, their cocoons, (which are 

 found fastened on walls, in crevices, and on fences and 

 branches of trees,) and putting them in a temperate room 

 in open boxes ; the greater part of them will thus be con- 

 verted into butterflies. 



V. Butterflies can also be obtained from the caterpil- 

 lars, by keeping them in open boxes, and feeding them 

 regularly with the leaves of the plants upon which we 

 have found them. We can in this manner observe the 

 whole process of the metamorphosis of the caterpillar 

 into a cocoon, and of the cocoon into a perfect butterfly.
