teat Bladder of Air Light, makes not an Experimentall conclusion, from such remembrances, of either heat, or weight, or lightnesse; but when he shall find that this Air, and all he meets with, this Lead, and many others are such, then he hath Experience, and by Experience he knows, that it is so with all other; if he shall reply and produce common language, that we usually say, that we had once Experience of such or such a passage; and therefore one tryal and sense, with remembrance of it, makes an experience.
