with creatures differing from thofe of others: fo that nothing of wliat 
is in(e. g.)^^^ Earth or Terr-aqueous Globe, is to be foundin any.of 
the other Planets, bi^t that every one of them is ftored with peculiar 
creatures, and even with fuch reafonabk ones, as are of another kind 
from the Men of our Earth. 
As to the Space thu is between thofe his Mundan Bodies (the Pla- 
nets^) he conceives it to be not any thing Material or Corporeal, 
but a Meer Jpace void of all body, which Space he defines to be as 
*cwcre thellniverfal Vefifel containing all Bodies; declaring herein his 
dlffent from D^j'C^r^^/, in whofe opinion Space or Extenfion can- 
not be without an extended fubftancc : whereas he (our Author) 
makes Space indifferent to the being or not being filled with bodies. 
Treaeing of this Space, which he calls Void, and efteeras fo in ics 
own nature, he maketh it Imraenfe and Infinite : And difcufling that 
fo much agitated Qucflion, whether there be a Vacuum^ he concludes 
it in the Affirmative, afferting, that not only all thofe parts of his 
Space, to which the Effluvia or nExpirations of his World do not 
reach, arevoidof all body, but alfo, that fo much of Water, Air, or 
any other thing as is exhaufted out of veffels,no other bodyfuccceding 
in its room, fo much there is of Vacuity there. To prove which lat- 
ter, he repeateth in this volume many of thofe Experiments of his, 
which the LearnM Schotm had publilli*t before ; adding fome others, 
together with fome improvements of his Engin ^ which was alfo de- 
fcribed by the faid Schontu^znd in which two very confiderablc things 
were deficient, as is obferv*d by Mr. ^oyle, the Noble Author of the 
New Experiments Phyfico- Mechanical touching the Jir, p.6,7. in the firft 
;E??^/f/^ Edition, printed A. 1660. at 6>.v/£?r^, and enrich't fince, by the 
fame, with 2i Continuation of New Experiments touching the Spring and 
J'Vetght of the Air^ and their efe^s, Sprinted A. 1669. in the fame place : 
Which two Treatifes being compared with what hath been heretofore 
publifh't by the aforefaid i^f/^^^m, andnow by this Author, it will 
cafily appear to fagacious and impartial Readers, to which of thcfe 
tW0 Gentlemen, Mr. Bo^Ie and Monf. De GeriekSy the Curious are 
nioft obliged, there having been at firft but fix experiments made by 
the latter of them, publiflu by Schsttm, in Arte Hydramicjo pneumatica^ 
about A. i656-,which afterwards were called Antiqua by the fame,an 
his Technica Cnriofa, printed A. 1662 S in which arc alfo recorded the 
other Experiments, cali'd Experimenta MagdehurgicaNova, two years 
after Mr, Boyles lately mentioned firfi; Book > the Cor^tinuation of which 
hath been abroad years before this of de Gericks himfclf, now 
under confideration.
