We may conclude from thefe Anafyfes , that Coral 
is not merely terreflrial and abforbent, but that it 
contains a volatile urinous Salt and bituminous 
Oil mixed with fome Earth, whereupon its Vir- 
tues depend ; and that its Rednefs is owing to the 
bituminous Oil, which it is poffible to Teparate 
from the Earth. Further, it appears that frelh 
Coral is confiderably different from that which has 
been long kept *, and that the Bark, perhaps, has 
more Energy than the other Part, which ought 
to be inquired into by Experiments. 
Diofcorides afcribes to Coral an aflringent Virtue, 
and fays it cools moderately, reftrains Excrefcences, 
deterges Scars of the Eyes, fills hollow Ulcers and 
Chaps, flops Fluxes of Blood and cures Difficulty 
of Urine. Thefe Virtues are not owing to an 
earthy, abforbent and drying Principle only, but 
alfo to its bituminous and balfamick Oil. It is 
prefcribed to Advantage in all Hemorrhages, Loofe- 
neffes and the Fluor albus . The Dofe is from gj. 
to gj. Moreover, it is faid to fortify the Heart, 
and to refifl Poifons and Malignity of the Humours, 
not only when taken inwardly, but like wife being 
hung externally upon the Body. But we are not 
fufficiently affured of this Property. 
Many Preparations of Coral are given in medi- 
cinal Writers, as the Magiflery, Salt, Tindture and 
Syrup, which at this Time are almofl univerfally 
rejedled. It is now chiefly ufed in Powder, being 
ground upon Porphyry to an Alcohol , and then is 
called prepared Coral. And this Preparation is pre- 
ferable to the reft ; for the Coral is fo much al- 
tered in the others, that it differs entirely from its- 
4e!f. Thus, the Magiflery is a Solution of Coral 
in acid Liquors precipitated by Alkalines. The 
'Salt is not a real Salt of Coral, but Cryftals ari- 
sing from an acid Salt united with it byDiffolution
