time, are thus at length fiVd into a friable kind of Hone, by the 

 petrifying fteam that comes from the earth ; or elfe they are exfu- 

 dations out of the ftones themfelves, whence are formed thofeex- 

 crefcenciis like warts in Animals i neither of which feem unagree- 

 able to their defcription in Tab./}. Fig. 8* 



48. But befide the Stalagmites, there are other concretions made 

 of much the fame materials, viz^. of a cold fort of water i thick- 

 ned with terrene and petrifying particles ; which yet becaufe of 

 their different mode of generation, have obtained a different, 

 and more fuitable name : And fuch are theflone s made of nothing 

 but fuch water, as it drops from the roofs and caverns of the 

 Rocks, and therefore called Stalactites , or Lapdes fiillatitii ; 

 which, if the drops defcend by the fides of the Rocks, and com- 

 ply with the ufual raggednefs of them, are then indeed of vari- 

 ous and therudeft forms, and by the work-men called Craume 7 * 

 But if the drops defcend from the top of a vault, or any more 

 prominent part of a Rock, in a direct line and free from the 

 fides, they are commonly then of a pyramidal form, as in Tab.'}. 

 Fig. 9. which is the reprefentation o^ftone of about nine inches 

 long, of a yellowiih colour, as it hung from the Rock in Hed- 

 dington Quarry, where without doubt it was produced much af- 

 ter the fame manner, as 1 fides at the ends of fpouts in Winter, by 

 a gradual defcent and congelation of the drops. 



49. Hither alfo muft be referred all forts of Spars, by the 

 Miners called Cawke, and the Latins, Fluores ; which (fay they) 

 yet retain fo much of a fluid, that with the heat of fire, like Ice 

 in the Sun, they melt and flow : an effecf, which though I could 

 not find it had upon ours without the help of Salts ; yet not 

 doubting at all, but that once they had been fluids, I could not 

 but accordingly give them place here. 



5 o. Whereof, there is fcarce any Rock whatever, whether 

 metalline or vulgar, which hasnotfome kind or other of them, 

 fliot in its feams or other hollows, which according to their diffe- 

 rent fubjects or matrixes, are fomtimes of different colours, and 

 frequently of di vets figures. 



51. As for colours , I have not obferved above two forts in 

 Oxford-Jhire, a light yellow, and a Pearl-colour'd white, where -
