have been ſpeaking of, comes to be more
attentively conſider'd, there will appear
two very conſiderable things to be de

ſome body not improperly calls it) is ſo
contriv'd, that to evacuate the Veſſel
there is requir'd the continual labor of
two ſtrong men for divers hours. And

Glaſs; the whole Engine is ſo made, that
things cannot be convey'd into it, where
