With creatures difFeririg from thofe of others s fo that nothiftg bf i^hat 
is in(e. g.)our Barth or Terr-aqueous Globe^is to be found in any;af 
the other Planets, but that every one of tbera is ftored with peculiar 
creatures, and even with fuch reafonable ones, as are of another iiitid 
i>^frorn the Men of our Earth. 
^ Asto thz Spac^thn is between thofe hirMundan Bodies (the P]a. 
■nets,) he conceives it to be not any thing Material or Corporeal, 
but a A'feer Jpace Yoid of ail body, which Space he defines to be as 
'^twere thellnivef fal Vefiel containing all Bodies^ declaring herein bis 
diffent from Des- Cartes, in whofe opinion Space or Extenlion can- 
not be without an el^tended fubftancc : whereas he (our Author) 
makes Sp^e indifferent to the being or not being filled with bodies. 
Treating of this^/?#«'£', which he cdk foid, and cfteemsfo in its 
' own nature, he maketh it Imnaenfeand InEnite And difcuffing that 
' fo ranch agitated Queftion, whether there be a Vacpmrn-, he concludes 
it in the Affirmative, afl'crting, that net only all thofe parts of his 
SfAcey Xo which the Effluvia or vExpirations of his World do not 
Teach, are void of all body, but alfo, that fo much of Water, Air, or 
any other thing as is exhaufted out of veffels,no other body fucceeding 
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 Sckttm bad publifli*t before : adding fome others, 
^ together with fome improvements of his Engin^ which was a[fo de- 
fcribed by thrfaid Schottm^^ini. in which two very confiderable things 
were deficient, asis obferv'd by Mr. Boyle, tlie Noble Author of the 
New Experlmms PhyficO' Mechanicd touching the Air, p. 6,7. in thcfirft 
.E^^/z/^ Edition, printed A. 1660. at 0A;/<?r^5/, and enrich't fince, bytbc 
fame, with ^Qontinmtion of Nersf Experiments touching the Spring mi 
^■Weight of the Air^ md their ejfeUs^ Iprinted A. 1669. in the fame piacc? 
• Which two Treatifes being compared with what hath been heretofore 
publifti'tby the aforefaid iS'i'/??^^^;/^, and now by this Author, it will 
eafily appear to fagacious and impartial Readers, to which of thcfe 
tw® Gentleman, Mr. Boyle and Monf. Gericke^ the Curious are 
raoft obliged, there havingbeenat firft but fix experiments madeby 
the latter of them, publiflit by Schmm^m Arte Hydrautico pnemaM^ 
about A. i656^which afterwards were called Antiqua, by the farae,,in 
his Technica Curiofa, printed A. 1662 h in which are alfo recorded the
