nographs on the smaller animals, like the 
one now before us, were more frequently 
published in this country, since it would

tional advantage Sweden derived from 
the entomological knowledge of Lin- 
nzeus — the very great services rendered 
to medicine and the arts, by the intro- 
duction of the silk-worm, the cochineal 
insect, and the Spanish fly.
