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 occupied 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, 

 excepting that in which the sense of smell was sup- 

 posed to reside. 



" The latter method appearing the more practicable 

 and decisive, we seized several bees, and, compelling 

 them to unfold the trunk, filled the mouth nearly 

 with flour paste. When this was dry enough, so that 

 they could not rub it off, they were released, and 

 none seemed to suffer any inconvenience from it. 

 They breathed and moved with the same facility as 

 their companions. Honey, however, did not attract 

 them, as they neither approached it, nor were they 

 affected by odours which, in other cases, are offensive 

 to them. Pencils were dipped in the oil of turpentine 

 and cloves, in ether, in fixed and volatile alkalis, and
