, their conjunction and
distillation made them exhibite these _Phaenomena_: _vid._ That, whereas
Spirit of Wine has no great, nor good scent, and moderately dephlegm'd Oyl
of Vitriol is wont to be inodorous; the Spirit, that first came over from
their mixture, had a scent not only very differing from Spirit of Wine, but
from all things else, that the Author ever smelt; the Odor being very
fragrant & pleasant, and so subtle, that in spight of the care taken in
luting the Glasses exactly together, it would perfume the neighbouring
parts of the _Laboratory_, and afterwards smell strongly at some distance
from the Viol, wherein it was put, though stopt with a close Cork covered
with two or three several Bladders. But, after this volatile and
odoriferous Spirit was come over, and had been follow'd by an Acid Spirit,
it was at last succeeded by a strongly stinking Liquor, &c.

But _Manum de Tabula_: the Book it self will certainly give a satisfaction
far beyond what here can be said of it. {198}

_Some New observations about the Planet _Mars_, communicated since the
Printing of the former sheets._

There was very lately produced a Paper, containing some observations, made
by Mr. _Hook_, about the Planet _Mars_; in the _Face_ whereof he affirmed
to have discovered, in the late months of _February_ and _March_, that
there are several _Maculae_ or _Spotted parts_, changing their place, and
not returning to the same Position, till the next ensuing night near about
the same time. Whence it may be collected, that _Mars_ (as well as
_Jupiter_, and the _Earth_, &c.) does move about his own _Axis_, of which a
fuller account will be given hereafter, God permitting. This short and
hasty intimation of it, is intended onely to invite others, that have
opportunity, timely to make Observations, (either to confirm, or rectify)
before _Mars_ gets out of sight.
