Dear Evgeny,
I did a quick read but I chose this:
" To remove water from a cup, it is necessary to fill it instead of water by the air. Further, in my
interpretation to remove air from a cup, we should fill the cup instead of air by the ether. Thus,
the cup can not be empty, only one medium can be replaced by another. Ether, according to
Aristotle, "is more subtle substance" than the air."
