* This draught of a general table may appear somewhat unintelligible, unless the inductive method of enquiry, delivered in the Novum Organum, be previously understood. We do not find that the author has any where prosecuted the enquiry into motion, according to this model. But naked as it is, it has a capital use; and shews the way of working in the tabular method, so as to demonstrate the whole process both of the mind and body, in conducting enquiries : which is the end it is here proposed to answer,

· For farther illustration, take another example of our tabular method of enquiry, in a less general, though copious subject; the affair of light and splendor.

A TABLE OF ENQUIRIES FOR THE PARTICULAR HISTORY OF LIGHT AND

SPLENDOR.

In the first place, draw up a table of all those bodies of every kind, which afford light: as, 1. the stars, fiery meteors, flame, wood, metals, and other ignited bodies. 2. Sugar, in scraping and breaking; glow-worms; salt water struck and scattered abroad; the eyes of certain animals; rotten wood; and large tracts of snow. Perhaps also the air itself may have a feeble light; adapted to the eyes of such creatures as see by night. 3. Iron and tin, when put to dissolve in aqua-fortis, bubble and boil up, without the assistance of fire, and also conceive heat;

Those who require farther instruction, may consult any of the other tables of enquiry, that are prosecuted; as, particularly, that prefixed to the History of Life and Death ; if the following one, for the History of Light and Splendor, be not sufficient. See also the Novum Organum, Part II. and the Preliminary Discourse to the abridgment of Mr. Boyle's Philosophical Works.

but whether they afford any light must be farther examined. 4. The oil of lamps sparkles in severe cold weather; and a certain degree of light has sometimes been observed, in a clear night, about a sweating horse ; and sometimes also, though rarely, about the hair of men's head, in the nature of a feeble lambent flame. A woman's stomacher has also been observed to shine upon rubbing ; but as the colour thereof was green, and alum is an ingredient in that dye, it was probably owing thereto, for it also crackled a little when it shone; but whether alum, in scraping or pounding, affords light, should be farther examined, though the force applied to it for this purpose, must perhaps be greater than that used to sugar, it being a more stubborn body. Some stockings also have been observed to shine, in pulling them off; whether this proceeded from sweat, or from alum used in the dye. Let all such instances be collected, and orderly disposed into this first or presence table, to shew in what subjects the thing we enquire after resides.

In the next place, let a table be formed of such bodies as yield no light at all, and yet have a great resemblance with those that do. Thus boiling water affords no light, nor air, though violently heated. Looking - glasses and dia

monds,* which reflect light so very remarkably, yet yield none that is original and their own, with other instances of the like kind; and among them let a diligent enquiry be made after those we call travelling instances, that is, where light is present and absent, transiently or by turns : thus an ignited coal gives light, yet, if strongly compressed, it presently ceases to be luminous ; but the crystalline matter of the glow-worm, though broken and divided into parts, retains its light for a small time, though it vanishes soon after. And this whole collection of instances, ranged in proper order, will form what we call the absence table, and exhibit all the bodies wherein the subject enquired after does not reside, though they nearly approach to those wherein it does reside.

Let it be next enquired, what light is more and what less intense and vibratory. Thus the flame of wood yields a strong light, the flame of spirit of wine a weaker, and the name of coals thoroughly ignited yields a light that is dusky, and scarce visible. And the proper instances of this kind, collected, will furnish out what we call the degree table.

* Do not diamonds, under certain circumstances, afford a light in the dark ? See Boyle and Stahl.
