Ost the Point Cagua, the Iron Guns of the Fort were ü-CorroJtd, «hatsome were near become Useless; beiag perforated aimost Iike Honey-Cömbs : But the Guns which lay in the Salt^Waltr, wer« not much Rod*-raag’d by Ruß,. as we found upon Taking up of sonae.

Many things receivc Dammage by the Air ; Not only Iron Rusts, bueeven Linnen Rots» and Silks once expos’d t» the Air d» Rot without lofingtheir Colour. If a Lancet be once Expos’d to the Air, ic will Ruß* thoughyou presenly put it up again : but if it be never Expos’d to the Air, xcwill hardly Ruß.

At Deal a cerrain Ale-Seiler will warrant, that the Ale, as he orders.it,shall be carry’d good to the Weß or E aß-Indus. His way to prepare it i&this, ('as he told tne himself,) heTwice Maßet it with Ftesii Malt, andXwice Boils it well: yet all thiskeptit not from Sowricg as I obscrv’d,during my stay there. Wc bought ot it to carry to Jamatca, aatd the»he directed us thus; Tocvery Rundlet of $ Gallons , after it is placcd iatheShip, not to be stirr’d any more, put in Two new-Laid Eggt Whole»and let them lie in it; he seid, that in a Fartnighi or little more, theWhole Egg-ßiells would be Dissolv’d, and the Eggt, become like Wind-Eggs, inclos’d only in aThinSkin: alter this, the Whole White would bePrey’d on, but the Tolk would not be Touch’d or Corrupted. By thismeans we did preserve the Ale to Jamaica, and it was much better that*at Deal.

Concerning the Thames Wattr , It is not only Observable, that in8 MontbsTimc it acquires a Sfkrituous Quollt y, so as to Bum i like Spirit ofWisse ; (and some Eaß-lndia-iships , I am inform’d, have run the hazardof Eiring, by holding a Candle near the Bang hole at the ffrst Opening ofthe Cask ;) but also that the Stmking of it is no Corruption, nor perhapsUnwholesome; for we Drank it all the way so as to hold our Noses, yethad no Sickneß, but we had a Proportion of Brandy each Weck, whichperhaps might Correct it. If you take off the Bang front any Cask thatStinkt, and let the Air come to it, it will in 24 Heurs become Sweet again;and if you take a Broora-stick and stir it about well, ic will become Sweetin 40t 5 Hours, Casting a Black Lee to the Bortom, which Remixes with it,and so occasions a 3^» or 4 tb Fermentation , and Steneb : after which itStmks no more. But though Thames Water upon Steneb do not Vutrtfy, yetOtbtr Waters (as far as bath been hitherto observ’d) do become lrrecaererable upon Stinking , and Dangerous to Drink.

I observ’d at Sea, after we were out of the Narrow , the Sea grewDarkffi, and after Perfect Axatre : yet was it much more Sah, the fartherwe w«nt, as I try’d by a Water-Tosfe which rose about half an Incb, abovethe Sea-tVater in the Downs , and at 2,4 Degrees more 1 Inebes, But after«hat I never observ’d any Difference unto Jamaica, the Sea being proba-bly so Impregnated with Salt, as not to imbibe more.

As to the Colour of the Sea, 1 conceive there is a great Variety in itand its Stearns, as in Grounds at Land; which may occasion the Sickneß insome Places more than in otbers: For the Sea Smdts Differeatly- in the
