that heat and moisture cause putrefaction. In England it is found not true; for many times there have been great plagues in dry years. Whereof the cause may be, for that drought in the bodies of islanders habituate to moist airs, doth exasperate the humours, and maketh them more apt to putrify or inflame : besides, it tainteth the waters, commonly, and maketh them less wholesome. And again in Barbary, the plagues break up in the summer months, when the weather is hot and dry.

Experiment solitary touching an error received about epidemical diseases,

384. Many diseases, both epidemical and others, break forth at particular times. And the cause is falsely imputed to the constitution of the air at that time when they break forth or reign; whereas it proceedeth, indeed, from a precedent sequence and series of the seasons of the year: and therefore Hippocrates in his prognostics doth make good observations of the diseases that ensue upon the nature of the precedent four seasons of the year.

Experiment solitary touching the alteration or pre

servation of liquors in wells or deep vaults.

385. Trial hath been made with earthen bottles well stopped, hanged in a well of twenty fathom deep at the least, and some of the bottles have been let down into the water, some others have hanged above, within about a fathom of the water; and the liquors so tried have been beer, not new, but ready

for drinking, and wine, and milk. The proof hath been, that both the beer and the wine, as well within the water as above, hath not been palled or deaded at all; but as good or somewhat better than bottles of the same drinks and staleness kept in a cellar. But those which did hang above water were apparently the best; and that beer did flower a little; whereas that under water did not, though it were fresh. The milk soured and began to putrify. Nevertheless it is true, that there is a village near Blois, where in deep caves they do thicken milk, in such sort that it becometh very pleasant: which was some cause of this trial of hanging milk in the well: but our proof was naught; neither do I know whether that milk in those caves be first boiled. It were good therefore to try it with milk sodden, and with cream; for that milk of itself is such a compound body, of cream, curds, and whey, as it is easily turned and dissolved. It were good also to try the beer when it is in wort, that it may be seen whether the hanging in the well will accelerate the ripening and clarifying of it.

Experiment solitary touching stutting.

386. Divers, we see, do stut. The cause may be, in most the refrigeration of the tongue; whereby it is less apt to move. And therefore we see that naturals do generally stut: and we see that in those that stut, if they drink wine moderately, they stut less, because it heateth: and so we see, that they that stut do stut more in the first offer to speak than

in continuance; because the tongue is by motion somewhat heated. In some also, it may be, though rarely, the dryness of the tongue, which likewise maketh it less apt to move as well as cold: for it is an affect that cometh to some wise and great men ; as it did unto Moses, who was " linguæ præpeditæ ;" and many stutters, we find, are very choleric men: choler inducing a dryness in the tongue.

Experiments in consort touching smells.

387. Smells and other odours are sweeter in the air at some distance, than near the nose; as hath been partly touched heretofore. The cause is double: first, the finer mixture or incorporation of the smell for we see that in sounds likewise, they are sweetest when we cannot hear every part by itself. The other reason is, for that all sweet smells have joined with them some earthly or crude odours; and at some distance the sweet, which is the more spiritual, is perceived, and the earthy reacheth not so far.

388. Sweet smells are most forcible in dry substances when they are broken; and so likewise in oranges or lemons, the nipping of their rind giveth out their smell more: and generally when bodies are moved or stirred, though not broken, they smell more, as a sweet-bag waved. The cause is double: the one, for that there is a greater emission of the spirit when way is made; and this holdeth in the breaking, nipping, or crushing; it holdeth also, in some degree, in the moving: but in this last there is

a concurrence of the second cause, which is the impulsion of the air that bringeth the scent faster upon us.

389. The daintiest smells of flowers are out of those plants whose leaves smell not; as violets, roses, wall-flowers, gilly-flowers, pinks, woodbines, vineflowers, apple-blooms, limetree-blooms, bean-blooms, &c. The cause is, for that where there is heat and and strength enough in the plant to make the leaves odorate, there the smell of the flower is rather evanid and weaker than that of the leaves; as it is in rosemary flowers, lavender flowers, and sweet-briar But where there is less heat, there the spirit of the plant is digested and refined, and severed from the grosser juice, in the efflorescence, and not before.

roses.

390. Most odours smell best broken or crushed, as hath been said: but flowers pressed or beaten do lose the freshness and sweetness of their odour. The cause is, for that when they are crushed, the grosser and more earthy spirit cometh out with the finer, and troubleth it; whereas in stronger odours there are no such degrees of the issue of the smell.

Experiments in consort touching the goodness and choice of water.

391. It is a thing of very good use to discover the goodness of waters. The taste, to those that drink water only, doth somewhat but other experiments are more sure. First, try waters by weight,

VOL. IV.

wherein you may find some difference, though not much; and the lighter you may account the better. 392. Secondly, try them by boiling upon an equal fire; and that which consumeth away fastest, you may account the best.

393. Thirdly, try them in several bottles or open vessels, matches in every thing else, and see which of them last longest without stench or corruption. And that which holdeth unputrified longest, you may likewise account the best.

394. Fourthly, try them by making drinks stronger or smaller, with the same quantity of malt; and you may conclude, that that water which maketh the stronger drink, is the more concocted and nourishing; though perhaps it be not so good for medicinal use. And such water, commonly, is the water of large and navigable rivers; and likewise in large and clean ponds of standing water; for upon both them the sun hath more power than upon fountains or small rivers. And I conceive that chalk-water is next them the best for going furthest in drink: for that also helpeth concoction; so it be out of a deep well, for then it cureth the rawness of the water; but chalky water, towards the top of the earth, is too fretting; as it appeareth in laundry of clothes, which wear out apace if you use such waters.

395. Fifthly, the housewives do find a difference in waters, for the bearing or not bearing of soap: and it is likely that the more fat water will bear soap best; for the hungry water doth kill the unctuous nature of the soap.

396. Sixthly, you may make a judgment of
