pors,and fill all vacuities, being carry ed aloft: this ill tested grcssnefs,when it comesto touch the coldness of the head or cap, and meets with the Glass, gathers like dewabout the skirts of it * and so running down the arches of the cap, it turns to water,and a pipe being opened that pertains to it', it runs forth largely , and the receiverHands to receive it as it drops: so will sweet water come from salt, and the salt tar-ryeth at the bottom of the vessel, and three pound of sale water, will give twopounds of fresh water ; but if the cap of the limbeck be of Lead, it will afford morewater, yet not so good.For Galen faith, That water that runs through pipes of Lead,ifit be drank, will cause an excoriation of the intestines. But I found a way

, How to get a greater quantity os fresh water, when we distilsalt water.

Make a cap of earth, like to a Pyramis, ail full of holes, that through the holes, Uri-nals of Earth or Glass may be brought in. Let their mouths stick forth, well lutedthat the vapor may not exhale; the cap after the fashion of the limbeck, must haveits pipe at rhe bottom running round, and let it drop forth at the nose of it. Septhis upon a brass Cauldron, that will hold much water; fill it with fait water, afterthat the Urinal;; and putting on their caps, when fire is put under, both the Urinalswill drop, and the cap rhat contain; others, by its pipe will drop out water alls:for the vapors rising from toe Cauldron of hoc water, will make the Urinals drop, andthe cap will drop wkhal. But if at Sea the commodity of such a vessel cannot be had.We may

Distil salt water otherwise ,

though but little. Dioscor ides (hews the old way of distillation; we may that waydistil sea water in ships, which Pliny shews also. Fleeces of wool extended aboutthe ship, are m ide wet by the vapors rising from the Sea, and sweet water is pressedout of them. But let us fee, whiter

Salt water may be made sr est another way.

Aristotle faith it, and Solomon before him, That all Rivers came from the Sea, and re-turn to the Sea; for by the secret passages under ground, the waters that are sentforth , leave their earthly and dry parts mixed wiin the earth, and they come forthpure and sweet. He faith, The cause why the fait water comes not forth, is, becauseit i; ponderous, and fettles, and therefore cnel/ hot-waters of salt-waters, can runforth , for they have a lightness that overfways the weight of the fait; for what ishot, is lightest: Adde, that waters running through the earth are much strained, andtherefore the heavior and thicker they are, the more,do they continually fink down,and are les: behind ; and the lighter they are, the more pure da they come forth andare levered. For as Salt is heavy , so sweet water is light; and so it cc me;, thatthey are sweet waters that run forth. This is the very, cause why salt-water, whenit moves and is changed, is made the sweeter, for motion makes it lighter and purer.Let u; fee now if we can imitate Nature: Fill then great vessels with earth , and setthem so one above another, that one may drean into another; and thus salt-waterdreaningthrsugh many vessels, may leave the salt behinde. I tried it through tenvessels, and it remain’d still salt: My friend said, that he made it sweet through t wen-ty vessels. Yet thus I thought to warn you of, that '11 earth is not fit for this use.Solinu t faith, That sea-water strain’d through clay will grow sweet ; and it is provedthat the fait is taken away, if you strain it often through thin sand of a River. Earththat lies in covered places, and under roots, is naught, for that is commonly salt ;asalso where Cattle are fl al led, which ColumeU* laith is naught for Trees, for that ittn.kes salt-water, what is strain’d from ir. Black earth is naught, for it makes thewaters sharp, but clay grounds make sweet waters. Paxamtu, Anaxagoras said.That the fait ness of the sea came from the Rivers, running through iatt places, andcommunicating that quality to the lea. Some approve River gravel for this use, audtheir reason is , because always sweet waters are found by the shores , and they faythis happens, because they are strain’d through the sand, and so grow fresh coiningfrom the salt-sea r for the sweet water that is found neer the sea, is not of the sea,but such water as comes from the tops of hills, through the secret channels of the
