rom that particular unquestionable one of Mr.
_Boyle_ and his worthy Company, who were the first Eye-witnesses of the
Tryals made,) that to _Oxford_, and in it, to Dr. _Christopher Wren_, this
Invention is due; and consequently, that all others, who discourse or write

Glasses_._

An Inquisitive _Parisian_ writes to his Correspondent in _London_, as
follows;

We received lately news from _Rome_, from a very Curious Person of our
