of the _Usefulness of Experimental Philosophy_, Part 2. Essay 2. pag. 53.
54. 55. Where 'tis also mention'd, that the fame of this Invention and of
the succeeding Tryals being spread, and particularly coming to the
knowledge of a foreign _Ambassadour_, that was Curious, and then resided in
_London_, it was by him tryed with some _Crocus Metallorum_, upon a
Malefactor, that was an inferiour Servant of his; with this success, that
the Fellow, as soon as ever the Injection began to be made, did, either
really or craftily, fall into a swoon; whereby, being unwilling to
prosecute so hazardous an Experiment, they desisted, without seeing any
other effect of it, save that it was told the Ambassadour, that it wrought
once downwards with him: Since which time, it hath been frequently
practised both in _Oxford_ & _London_; as well before the _Royal Society_,
as elsewhere. And particularly that Learned {130} Physitian, Dr. _Timothy
Clerk_, hath made it part of his business, to pursue those Experiments with
much industry, great accurateness, and considerable observations thereon;
which above two years since, were by him produced and read before the
_Royal Society_, who thereupon desired him, as one of their Members, to
compleat, what he had proposed to himself upon that subject, and then to
publish the same: the Effect whereof 'tis hoped, will now shortly appear,
and not prove unwelcome to the Curious.

Some whereof, though they may conceive, that liquors thus injected into
Veines without preparation and digestion, will make odde, commotions in the
Blood, disturb Nature, and cause strange Symptoms in the Body, yet they
have other thoughts on Liquors, that are prepared of such things, as have
passed the Digestion of the Stomach; for example, of Spirit of Urine, of
Harts-horne, of Blood &c. And they hope likewise, that besides the
_Medical_ Uses, that may be made of this _Invention_, it may also serve for
_Anatomical_ purposes, by filling, after this way, the vessels of an Animal
as full, as they can hold, and by exceedingly distending them, discover
_New_ Vessels, &c: But not now to enlarge upon the Uses, the Reader may
securely take this Narrative, as the naked real Matter of Fact, whereby
'tis as clear, as Noon day (both from the Time, and irrefragable Testimony
of very many considerable Persons in that University, who can jointly
attest it; as well as f
