the fmell is not very unpleafaht, and fomewhat refernbles that of 
myrrh. The aloe hepatica E. P. and barbadenfis L. P. the Hepatic, 
Barbadoes, or common aloes, is chiefly brought from Barbadoes ; the 
beft fort in large gourd fhells, an inferior kind in pots, and a ftill 
worfe in calks ; is darker coloured than the foregoing, and not fo clear 
or bright. It is generally drier and more compact, though fometimes, 
efpecially the calk fort, quite foft and clammy. Its fmell is much 
ftronger and more difagreeable : the 'tafte intenfely bitter and nau- 
feous, with little or nothing of the aromatic flavour of the ibcotonne. 
Another kind of aloes obtained from the aloe guineenfis cabaliina 
vulgari fimilis fed tota maculata*, is alfo kept in the limps, and ce 
aloe cabaliina, or horfe aloes. This is eafily diitinguiilied from both 
the foregoing, by its ilrong rank fmell : in other refpedts it agrees 
pretty much with the hepatic, and is now not unfrequently fold in 
its place. Sometimes it is prepared fo pure and bright as fcarcely to 
be diftinguifhable by the eye, even from the focotorine, but its 
ofTenfive fmell readily betrays it ; and if this alfo mould be diflipated 
by art, its wanting the aromatic flavour of the finer aloes will be a 
fufficient criterion. This aloe is not admitted into the Materia Me- 
dica, and is employed chiefly by farriers. , 
All the kinds of aloes confift of a refm united to a gummy matter, 
and diflfolve in pure fpirit, proof fpirit, and proof fpirit diluted with 
half its weight of water; the impurities only being left. They dif- 
folve alfo by the afliftance of heat in water alone ; but as the liquor 
rows cold, the refmous parts fubfide. 
The hepatic aloes is found to contain more refin and lefs gum 
than the focotorine, and this than the caballine. The refins of all 
the forts, purified by fpirit of wine, have little fmell: that obtained 
from the focotorine has fcarce any perceptible tafte; that of the 
hepatic, a flight bitterifh reliih; and the refm of the caballine, a 
little more of the aloetic flavour. The gummy extracts of all the 
forts are lefs difagreeable than the crude aloes:* the ex;radt of toco- 
torine aloes has very little fmell, and is in tafte not unpleasant: that 
of the hepatic has a fomewhat ftronger fmell, but is rather more 
agreeable in tafte than the extract of the focotorine: the gum or tne 
caballine retains a confiderable fliare of the peculiar rank fmell of
