THE SENSE OF TASTE AND GUSTATORY ORGANS. 631 
last and finest experiment, I placed before them a concentrated 
solution of sugar-candy. They smelt and tasted it, and yet, 
although they had been kept several hours without food, they 
would not feed upon it. I cut off their antenne, when they 
took it in small quantity, but soon left it, although they took 
pure honey with avidity.’ 
Will’s experiments with Wasps are exceedingly interesting. 
He placed coarsely-powdered white sugar on a paper in the 
open air, and after allowing them to feed on it for some 
hours, he replaced it by powdered alum. ‘This the Wasps 
attempted to take, but scarcely had they tasted it than they 
started back in the drollest manner and cleaned their tongues 
repeatedly with their fore-feet to rid themselves of the disgust- 
ing substance. 
‘Their first sad experience did not, however, prevent their 
making a second trial, with similar results, after which 
most of them flew away. One pair of obtuse individuals, 
however, persisted in trials of the alum; but when they had 
taken a certain amount they rolled themselves upon the table, 
evidently in the greatest discomfort,’ although they also flew 
away sooner than he expected. 
Other Wasps came, but by three o'clock in the afternoon— 
long before these insects are accustomed to give up work— 
no more came to taste the alum.

This paper is one of the most interesting contributious to the better 
understanding of the senses in insects with which I am acquainted, and 
should be studied by every young naturalist. It is a model of research 
and experiment,
