theft oft', according to the Courfe of Circulation, to 
wrap up the Bafts of this Medicine, in Sulphurs, and 
fuch like Subftances, as follow it into its laft Divifion, 
without giving it any Afperities to make it a# as

and with Sulphur. 
This way of thinking on thefe Occafions, feems to

of thofe Subftances, which by a natural Preparation 
are fitted for Operation in the minuteft part of an 
Animal Body, fuch as thofe of the Aromatick Kind, 
all which more or left, according to their greater, or
