brought in _Specimens_ for the Improvement of _Astronomy_, _Geography_, _Navigation_, _Optics_; all the Parts of _Agriculture_, the _Garden_ and the _Forest_; _Anatomy_ of _Plants_, and _Animals_; _Mines_ and _Ores_; _Measures_ and _Æquations_ of _Time_ by accurate _Pendulums_, and other Motions, _Hydro_- and _Hygrostatics_, divers _Engines_, Powers and _Automata_, with innumerable more _luciferous_ particulars, subservient to human life, of which Dr. _Glanvil_ has given an ample and ingenious _Accompt_ in his learned Essay: And _since_ in the _Posthumous_ Works of Dr. _Hooke_, lately publish’d by the most obliging Mr. _Waller_, already mention’d. This is (_Reader_) what they have done; and they are but _part_ of the _Materials_ which the _Society_ have hitherto _amassed_, and prepared for this great and _Illustrious Work_; not to pass over an infinity of _solitary_, and loose _Experiments_ subsidiary to it, gathered at no small Pains and Cost: For so have they hitherto born the _Burden and Heat of the day alone_; _Sapping_ and _Mining_ to lay the _Foundation_ deep, and raise a _Superstructure_ to be one day perfected, by the joint _Endeavours_ of those who shall in a _kinder_ Age have little else to do, but the _putting_ and _cementing_ of the _Parts_ together, which to _collect_ and fit, have cost them so much Solicitude and Care. _Solomon_ indeed built the glorious _Temple_; but ’twas _David_ provided the _Materials_: Did Men in those days insolently ask, _What he had done_, in all the time of that tedious preparation? I beseech you what _Obligation_ has the _R. Society_ to render an _Accompt_ of their Proceedings to _any_ who are not of the _Body_, and that carry on the _Work_ at their own _expence_ amidst so many Contradictions? It is an _Evil Spirit_, and an _Evil Age_, which having sadly _debauch’d_ the _Minds_ of Men; seeks with Industry to blast and undermine all _Attempts_ and Endeavours that signifie to the Illustration of _Truth_, the discovery of _Impostors_, and shake their sandy Foundations.
