INTERNAL ANATOMY OF INSECTS. 135- 
be deduced from the circumstance of the bees imbibing 
the juices of fruzts of various kinds as they are well known 
to do*, It seems therefore evident that the honey col- 
lected by bees undergoes some modification in their ho- 
ney-stomach before it is regurgitated into the cells, and 
therefore may be regarded in some degree as a peculiat 
secretion. 
Huber says that he has ascertained by a great num- 
ber of observations that electricity is singularly favour- 
able to the secretion of the substance of which honey is 
formed by flowers; the bees never collect it in greater 
abundance, nor is the formation of wax ever more active, 
than when the wind is in the south, the air humid and 
warm, and a storm gathering®. 
viii. Wax generally transpires through the pores of 
the skin of those insects that produce it, either partially 
or generally, and it is secreted from honey or other sac- 
charine substances taken into the stomach. In the hive-- 
bee, as has been before stated, it is produced partially‘, 
but in many other insects it is a general transudation of 
the body. This is particularly the case with a large 
number of the Homopterous Hemiptera; and those flo- 
coons that look like cotton, and cover the body of seve- 
ral Chermes and Aphides, if closely examined will be 
found of the nature of waz: this I have particularly no- 
ticed with respect to Chermes Fagz, in which the cotton- 
like flocoons are often so long as to cause the insect to 
look like a feather, and a leaf covered by them exhibits a: 
very singular appearance, as if clothed with the fine down 
of a swan’. Probably the white powder or threads that
