86 OF THE SENSES OF 
on approaching the thorax, abdomen, or stigmata of 
the thorax. 2. We then took a fine pencil, that it 
might reach every point of the head, and brought it 
near the antenne, the eyes, and protruded trunk of a 
bee in the act of feeding, but without producing the 
least effect. It was otherwise on carrying it near the 
cavity of the mouth, above the insertion of the pro- 
boscis. At that instant the bee receded, left the 
honey, and, beating its wings, while moving about in 
much agitation, it would have taken flight had not 
the pencil been withdrawn. Having renewed its 
repast, we resumed the application, always carrying 
the impregnated portion near the mouth. The bee, 
now quitting the honey, fixed upon the table, and 
fanned itself during some minutes. The organ of 
smelling, therefore, seems to reside in the mouth 
itself, or in the parts contiguous. 
“ Bees not oceupied in feeding appeared more 
sensible of the odour of the turpentine. They were 
affected by it at a greater distance, and speedily took 
flight, whereas, when so engaged with the trunk 
immersed in honey, several parts of the body might 
be touched by the pencil without their withdrawing. 
We inferred that their attention was either absorbed 
by the smell of the honey, or their organs less exposed 
to the effluvia. This could be ascertained in two 
ways,—either by covering all parts of the body with 
a varnish, and leaving the sensible organ free ; or 
allowing the whole parts to remain untouched,
