"For instance, suppose the same Water be pour'd out into different Vessels, that which is in this Vessel may possibly be something warmer than that which is in another, tho' 'tis the same Water still, and so every degree of Heat and Cold in this Water in the Several Vessels, will represent the Specifick difference which there is in Animals: And as that Water is all one and the same, so is that Animal Spirit One, tho' in some respect there is a sort of Multiplicity. And so under this Notion he look'd upon the whole Species of living Creatures, to be all One."
