Of Earths. 
where it lies m little Veins containing much water. Sup- 
pofed to be the materiaprima ol white Marble. 
A White EARTH lying in a Load degenerated from Tin. 
very gritty, and infenfible ot Acids. 
A White EARTH, with a Ray of Red 5 very foft, with¬ 
out any grit, and in affected with Acids. Nor' hath it the 
common Taft of Boles, but is altogether inlipid. Found 
in the fame place, as the former 5 but in different Veins. 
Suppofedto be the Embrio of white and red Marble. 
A BOLE of a yellowifh fandy colour 5 fomewhat gritty 
and friable. 
SILESIAN BOLE. Of a redifh yellow, exactly like the 
paler Emplaftrutn de Minio. As denfe as any other, crack¬ 
ling a little betwixt the Teeth. Yet without the leaft Par¬ 
ticle ot Grit 5 feels as ftnooth as Caftile-Soap 5 fcrapes with 
a glofs 5 and breaks like Bees-Wax , or the Salve above-faid. 
Tafteth like other Boles. 
The BOHEMICK fealed BOLE. It agrees in all pro¬ 
perties with the former 5 laving that it hath fomewhat more 
of red. 
The HEPATICK BOLE of LEMNOS. Of kin to the 
red Lemnian. And anfwers to that which Wormiws defcribes 
by the Name of Terra [igillata liepatica. It ftirreth not witli 
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,as applied 
to Medical Ufe, to be this, That feme arc not affected with 
Acids ; others are -IThofeT auperes or Fatuee ; coming nearer 
to limple or meer Earths 5 Thefe Saline, 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 
firme Marble-Rock■ Suppofed to be the Embrio of the red 
Marble. 
Red LEMNOS EARTH. As red as Radle; but much 
more clofe and coherent, and fo colours not the Fingers. 
(V) Likde TheophraJhis (a) reckons up three forts of Terra Lemnia 5 fc. 
the Deep Red, the Pale Red, and the Whitilh.
