The other essay is concerning the porosity of solid bodies, which the author 

 proves, first, a priori, from the origin and formation of divers hard bodies; 

 from the great disparity found in the specific gravities of such bodies as the 

 eye does not perceive to be porous ; from the frame and constitution of solid 

 bodies ; for even they consist of particles which cannot be supposed to touch 

 one another so exactly, as not to leave any pore between them. 2dly, a pos- 

 teriori, from some experiments and observations, arguing the porousness of 

 wood, earthen vessels, stones, metals, and even glass itself.

In this magic, the author gives the several divisions made use of by authors, 

 different according to the divers conceptions they had of its parts. He makes 

 it first, either human or diabolical, with their respective species. Secondly, 

 natural, or transnatural, under which last he comprehends the transmutation 

 of metals ; under natural come all the surprizing efi^ects of art, such as artifi- 

 cial fires, malleable glass, incombustible linen, cures of diseases by magnetism 

 or transplantation, strange efi^ects in chemistry and mathematics, &c. 



After this general account, follows a very particular enumeration of its species, 



* John Dolaeus was a multifarious, and not always a judicious compiler, in the l/th century.

 some other tracts.
