the air seven drams, the balance in the water weigheth only four drams and eighteen grains; and abateth of the weight in the air two drams and forty-two grains; the depth observe as above.

In stone and stone, the same weight of seven drams equally in the air, the balance in the water weigheth only two drams and twenty-two grains; and abateth of the weight in the air four drams and thirty-eight grains; the depth as above.

In brass and brass, the same weight of seven drams in each balance, equal in the air, the balance in the water weigheth only four drams and twenty-two grains; and abateth in the water two drams and thirty-eight grains; the depth observed.

The two balances being weighed in air and water, the balance in the air over-weigheth the other in the water one dram and twenty-eight grains; the depth in the water as aforesaid.

It is a profitable experiment which sheweth the weights of several bodies in comparison with water. It is of use in lading of ships, and other bottoms, and may help to shew what burden in the several kinds they will bear. Certain sudden thoughts of the Lord Bacon's, set

down by him under the title of EXPERIMENTS FOR PROFIT.

MUCK of leaves : muck of river, earth, and chalk : muck of earth closed, both for salt-petre and muck: setting of wheat and peas: mending of crops by steeping of seeds : making peas, cherries, and strawberries come early: strengthening of earth for often returns of radishes, parsnips, turnips, etc. making great roots of onions, radishes, and other esculent roots : sowing of seeds of trefoil: setting of woad : setting of tobacco, and taking away the rawns : grafting upon boughs of old trees : making of a hasty coppice : planting of osiers in wet grounds : making of candles to last long : building of chimnies, furnaces, and ovens, to give heat with less wood: fixing of logwood: other means to make yellow and green fixed : conserving of oranges, lemons, citrons, pomegranates, etc. all summer: recovering of pearl, coral, turcoise colour, by a conservatory of snow : sowing of fennel : brewing with hay, haws, trefoil, broom, hips, brambleberries, woodbines, wild thyme, instead of hops, thistles: multiplying and dressing artichokes. Certain experiments of the Lord Bacon's, about the

commixture of liquors only, not solids, without keat or agitation, but only by simple composition and settling.

SPIRIT of wine mingled with common water, although it be much lighter than oil, yet so as if the first fall be broken, by means of a sop, or otherwise, it stayeth above; and if it be once mingled, it severeth not again, as oil doth. Tried with water coloured with saffron.

Spirit of wine mingled with common water hath a kind of clouding, and motion shewing no ready commixture. Tried with saffron.

A dram of gold dissolved in aqua regis, with a dram of copper in aqua fortis, commixed, gave a green colour, but no visible motion in the parts. Note, that the dissolution of the gold was, twelve parts water to one part body : and of the copper was, six parts water to one part body.

Oil of almonds commixed with spirit of wine severeth, and the spirit of wine remaineth on the top, and the oil in the bottom.

Gold dissolved, commixed with spirit of wine, a dram of each, doth commix, and no other apparent alteration.

Quicksilver dissolved with gold dissolved, a dram of each, doth turn to a mouldy liquor, black, and like smiths water.

Note, the dissolution of the gold was tweīve parts water, ut supra, and one part metal : that of water was two parts, and one part metal.

Spirit of wine and quicksilver commixed, a dram of each, at the first shewed a white milky substance at the top, but soon after mingled.

Oil of vitriol commixed with oil of cloves, a dram of each, turneth into a red dark colour; and a substance thick almost like pitch, and upon the first motion ga. thereth an extreme heat, not to be endured by touch,

Dissolution of gold, and oil of vitriol commixed, a dram of each, gathereth a great heat at the first, and darkeneth the gold, and maketh a thick yellow.

Spirit of wine and oil of vitriol, a dram of each, hardly mingle; the oil of vitriol going to the bottom, and the spirit of wine lying above in a milky sub, stance. It gathereth also a great heat, and a sweetness in the taste.

Oil of vitriol and dissolution of quicksilver, a dram of each, maketh an extreme strife, and casteth up a very gross fume, and after casteth down a white kind of curds, or sands; and on the top a slimish sub, stance, and gathereth a great heat.

Oil of sulphur and oil of cloves commixed, a dram of each, turn into a thick and red-coloured substance ; but no such heat as appeared in the com: mixture with the oil of vitriol.

Oil of petroleum and spirit of wine, a dram of each, intermingle otherwise than by agitation, as wine and water do; and the petroleum remaineth on

the top.

Oil of vitriol and petroleum, a dram of each, turn into a mouldy substance, and gathereth some warmth; there residing a black cloud in the bottom, and a monstrous thick oil on the top.

Spirit of wine and red-wine vinegar, one ounce of each, at the first fall, one of them remaineth above, but by agitation they mingle.

Oil of vitriol and oil of almonds, one ounce of each, mingle not ; but the oil of almonds remaineth above.

Spirit of wine and vinegar, an ounce of each, commixed, do mingle, without any apparent separation, which might be in respect of the colour.

Dissolution of iron, and oil of vitriol, a dram of each, do first put a inilky substance into the bottom, and after incorporate into a mouldy substance.

Spirit of wine commixed with milk, a third part spirit of wine, and two parts milk, coagulateth little, but mingleth; and the spirit swims not above.

Milk and oil of almonds mingled, in equal portions, do hardly incorporate, but the oil cometh above, the milk being poured in last; and the milk appeareth in some drops or bubbles.

Milk one ounce, oil of vitriol a scruple, doth coagulate; the milk at the bottom, where the vitriol goeth.

Dissolution of gum tragacanth, and oil of sweet almonds, do not commingle, the oil remaining on the top till they be stirred, and make the mucilage somewhat more liquid.

Dissolution of gum tragacanth one ounce and a half, with half an ounce of spirit of wine, being commixed by agitation, make the mucilage more thick.

The white of an egg with spirit of wine, doth bake the egg into clots, as if it began to poch.

One ounce of blood, one ounce of milk, do easily incorporate.

Spirit of wine doth curdle the blood.

One ounce of whey unclarified, one ounce of oil of vitriol, make no apparent alteration.

One ounce of blood, one ounce of oil of almonds, incorporate not, but the oil swims above.

Three quarters of an ounce of wax being dissolved upon the fire, and one ounce of oil of almonds put together and stirred, do not so incorporate, but that when it is cold the wax gathereth and swims upon the top of the oil.

One ounce of oil of almonds cast into an ounce of sugar seething, sever presently, the sugar shooting towards the bottom. A catalogue of bodies attractive and not attractive,

together with experimental observations about attraction.

THESE following bodies draw: amber, jet, diamond, sapphire, carbuncle, iris, the gem opale, amethyst, bristollina, crystal, clear glass, glass of antimony, divers flowers from mines, sulphur, mastic, hard sealing-wax, the harder rosin, arsenic.

These following bodies do not draw: smaragd, achates, corneolus, pearl, jaspis, chalcedonius, alabaster, porphyry, coral, marble, touchstone, hæmatites, or bloodstone; smyris, ivory, bones, ebon-tree, cedar, cypress, pitch, softer rosin, camphire, galbanum, ammoniac, storax, benzoin, loadstone, asphaltum.*

These bodies, gold, silver, brass, iron, draw not, though never so finely polished.

In winter, if the air be sharp and clear, sal gemmeum, roch allum, and lapis specularis, will draw.

These following bodies are apt to be drawn, if the mass of them be small : chaff, woods, leaves, stones, all metals leaved, and in the mine; earth, water, oil,

• The drawing of iron excepted.
