3 48 Of Earths. Part III. 
where it lies m little Veins containing much water. Sup- 
pofed to be the materia prima of white Marble. 
A White EARTH lying in a Load degenerated from T'm. 
very gritty, and infenfible of Acids, 
A White EARTH, with a Ray of Red $ very foft, with- 
out any grit, and inaffeclied with Acids. Nor hath it the 
common Taft of Boles, but is altogether infipid. Found 
in the fame place, as the former 3 but in different Veins. 
Suppofed to be the Embrio of white and red Marble. 
A BOLE of a yellowifh fandy colour 3 fomewhat gritty 
and friable. 
SILESIAN BOLE. Of a redilh yellow, exadly like the 
paler Emplaftrum de Mink. As denfe as any other, crack- 
ling a little betwixt the Teeth. Yet without the leaft Par- 
ticle of Grit 3 feels as fmooth as Caftile-Soay 5 fcrapes with 
a glofs 3 and breaks Hke Bees-Wax, or the Salve above-faid. 
Tafteth like other Boles. 
The BOHEMICK fealed BOLE. It agrees in all pro- 
perties with the former 3 faving that it hath fomewhat more 
of red. 
The HEP ATICK BOLE of LEMNOS. Of kin to the 
red Lemnian. And anfwers to that which Wormius defcribes 
by the Name of Terra figillata hepatica. It mrreth not with 
Acids. 
ANOTHER of the fame more PALE. Somewhat 
harder than the Armenian Bole. It makes a fmall ebullition 
with Oil of Vitriol, and with Spirit of Nitre a very ftrong 
one. 
I take the principal Difference between Earths,2s applied 
to Medical Ufe, to be this, That fome are not affected with 
Acids 3 others are :Tho(c,Pauperes or Fatux 3 coming nearer 
to fimple or meer Earths 3 Thefe Salhie, or impregnated 
with a Mineral Alkali, and therefore of greater energy. 
A fmooth and pale redifh CLAY, lying in a little vein, 
running Eaft and Weft, through a great Pillar of Sand, in a 
feme Marble-Rock. Suppofed to be the Embrio of the red 
Marble. 
Red LEMNOS EARTH. As red as Radle h but much 
more clofe and coherent, and fo colours not the Fingers. 
(a) Lib. de Theophraftus (a) reckons up three forts of Terra Lemma 3 fc. 
U ^ the Deep Red, the Pale Red, and the Whitifh.
