ading upon thofe bodies diffoluble in them^and the Texture 
of thofe bodies before and after the procefi. 9. By con- 
fidering, by what and how many means, fuch and (uch

He goes on to offer his thoughts about the Pores of bo- 
dies^ and 2i l{ind oiValves in wood, about ipontaneous gene- 
ration arifing from the Putrefaftion of bodies, about the na- 
ture of the Vegetation of mold, mufliromes, mofs. fpunges, 
to the laft of which he Icarce finds any Body like it in tex- 
ture. He adds, from the naturall contrivance , that is 
found in the leaf of a Nettle, how the flinging pain is crea- 
ted, and thence takes occafion to difcourfe of the poyfoning 
of Darts. He fubjoyns a curious defcription of the (hape, 
Mechanifm and ufe of the jling of a Bee , and fhews the ad- 
mirable Providence of Nature in the contrivance and fa- 
brick of Feathers for Flying. He delivers thofe particulars 
about the Figure, parts and ufe of the head^ feet, and wings 
of a Fly, that are not common. He obferves the various 
wayesof the generations of Infedbs, and difcourfes handr 
fomelyof the means, by which they fccmto aft fo prudent- 
ly. He taketh notice of the Mechanical reafon of the Sli- 
der s Fabrick, and maketh pretty Obfervations on the hunt- 
ing Spider^ and other Spiders and their Webs. And what 
he notes of a Flea , Loufe , Mites, and Vinegar- worms^ 
cannot but exceedingly plcafe the curious Reader. 
Having difpatched thefe Matters, the Author offers 
his Thoughts for the explicating of many Ph£nomena of the 
Air 3 from the Inflexion , or from a Mfilti^licate RefraSi- 
on of the rays of Light within the Body of the Atmoffhere ^ 
and not from a KefraBion caufed by any terminating fn- 
ferficies of the Air above , nor from any (iich exaftly de- 
fined Juperficies within the body of the Atmofihere : which 
conclufion he grounds upon this , that a medium , whofe 
parts are unequally denje , and mov'd by various motions 
and tranfpofitions as to one another ^ will produce all thefe
