CHAP. 6. (5.)—THE MEANING OF THE TERMS COMMOSIS, PISSO-
CEROS, AND PROPOLlS.
The persons who understand this subject, call the substance
which forms the first foundation of their combs, commosis,1
and the third propolis;3
which last is placed
between the other layers and the wax, and is remarkable for
its utility in medicine.4
The commosis forms the first crust
or layer, and has a bitter taste; and upon it is laid the pissoceros, a kind of thin wax, which acts as a sort of varnish.
The propolis is produced from the sweet gum of the vine or
the poplar, and is of a denser consistency, the juices of flowers
being added to it. Still, however, it cannot be properly termed
wax, but rather the foundation of the honey-combs; by means
of it all inlets are stopped up, which might, otherwise, serve
for the admission of cold or other injurious influences; it has
also a strong odour, so much so, indeed, that many people use
it instead of galbanum.
