Transposed the colours again. 



At 8.35 slie returned to the blue, and at 8.39 went ;

That bees can distinguish scents is certain. On the 5th Oct. 

 I put a few drops of Eau de Cologne in the entrance, and imme- 

 diately a number (about fifteen) of bees came out to see what was 

 the matter. Eose-water also had the same effect ; and, as will 

 be mentioned presently, in this manner I called the bees out 

 several times ; but after a few days they took hardly any notice 

 of the scent. For instance, on the I7th Oct. I tried them with 

 twenty drops of Eau de Cologne, the same quantity of essence of 

 violet, of lavender-water, of essence of musk, of essence of Pat- 

 chouli, and of spirits of wine ; but they took no apparent notice 

 of any of them.
