So in frosts, the inside of glass windows gathereth a dew; if not more without.
Qu. Whether the sweating of marble and stones be in frost or towards rain.
Oil in time of frost gathereth to a substance as of tallow, and it is said to sparkle some time so as it giveth a light in the dark.
The countries which lie covered with snow have a hastier maturation of all grain than in other countries, all being within three months or thereabouts.
Qu. It is said that compositions of honey, as mead1 do ripen and are most pleasant in the great colds.
The frosts with us are casual and not tied to any months, so as they are not merely caused by the recess of the sun, but mixed with some inferior causes. In the inlands of the northern countries as in Russia the weather for the three or four months of November, December, January, February, is constant, vt. clear and perpetual frost without snows or rains.
There is nothing in our region, which, by approach of a matter hot, will not take heat by transition or excitation.
There is nothing hot here with us but is in a kind of consumption if it carry heat in itself; for all fired things are ready to consume, chafed things are ready to fire, and the heat of men's bodies needeth aliment to restore.
The transition of heat is without any imparting of substance, and yet remaineth after the body heated is withdrawn; for it is not like smells, for they leave some airs or parts; not like light, for that abideth not when the first body is removed; not unlike to the motion of the loadstone, which is lent without adhesion of substance, for if the iron be filed where it was rubbed, yet it will draw or turn.2

And below this again he has written first in a clear and careful hand the word new, and afterwards in a hurried and careless hand the word Vetus.

THE following fragment was first published by Dr. Rawley in 1688, among the Opuscula Philosophica; and as he does not mention it among the works composed by Bacon during the last five years of his life, we may conclude that it was written before the Sylva Sylvarum. It may have been the commencement of the "Tables de Sono" which, as we learn from the Commentarius Solutus, he was preparing in the summer of 1608. If so, it must have been meant for the second in the series,― viz. Sylva, sive Carta Mater; whence its second title, "Sylva Soni et auditûs; " and had it been proceeded with, the several tables-tabula essentia et præsentiæ, tabula absentiæ in proximo, tabula graduum, &c.-would have followed in order. As far as it goes however, it must be classed among the rough collections, not yet reduced to order for the use of the understanding, and appears to aim at precisely the same object as the investigation concerning Sound which occupies the greater part of the second and third centuries of the Sylva Sylvarum (101-290.); being itself in fact one of the Sylva of which the great Sylva was made up. By that investigation therefore it must be considered as superseded.
I do not know that any inference of importance can be drawn from a comparison of the two; but to make the comparison easier, I have referred in the footnotes to the corre
