The next way is by affeding its Motion, fo that it 
difcharges great quantities out of the Blood ; by thefe 
means the quantity of the Blood being leffer, it gives 
fewer Spirits, when it is broke down ; and is not fo ca- 
pable to be fo Comminuted, becaule of the parts of 
Blood not preffing (b much one upon the other in the

Spirits, and fits them to be (eparated ,• or any confide-

The Second Condition for hindering fo great a Prepa-
