sHn 5 after this, the whole I^Wr-^ would be prey 'don, but the To!k 
would not be touch/d or corrupred. By this means we did prefer ve 
the Ale to ^dmdica, and k was much better, than at D^4/, I was 
told fince by fome others that the Experiment is iifoal vvithtlicm^ to 
keep Ale in England a quarter oFa year : And if Eggs be thus pat 
into March-heefy they preferve ic from growing ever harfli. They 
muft be put in, after the Liquor has done working. 
Concerning the Thames-tvater^ it is not only obfcrvable, that in 
eight months time it acquires a Spirituous qualityj fo as to burn like 
Spirit of Wine ; and fome Baft-Indid lliips, 1 am infarn^eJ, have 
run the hazard of firing by holding a Candle near the Bung hole at 
thefirft opening of the Cask 5 ) buralfo that the (linking of it is no 
Gorrnption, nor perhaps unwholefome % for we drank it all the way^ 
fo as to hold our Nofes^ yet had no fieknefs^ but we had proportion 
q( Brandy each week3 which perhaps might corredir. If you take 
off the Bung from any Cask that ftinks, and let the Air come to it, 
it will in 24 hours become fweet again. And if you take a Broom- 
ftick^ and ftir it about well, it will become fweet in 4 or 5 hours caft- 
ing a black Lee to the bottom^ which remixes with ir, andfooccafi- 
ons a third or fourth fermentation, and ftench § after which it ftinks 
no more. But, though Thames-neater upon ftench do not putrifie^ 
yet other Waters (as far as hath been hitherto obferved) do become 
irrecoverable upon ftinking, and dangerous to drink. 
I obferv'd at Sea^ that though Glafder fay , the water, as it grovvs 
S^/^^r^ becomes Cr^-if;^^^, yet that is falfe. For, after we were out of 
the Narrow, the Sea grew darkifh ^ and after perfed A^re^ yet 
was is much more Salt, the farther we went: as I tried by a Water- 
foifeoi Glafs, with Quick- Giver at the one end, itrofe about half 
an inch above the Sea- water in the Downs 5 and at 24 degrees more, 
2 inches. But after that, I never obferved any difference nnio^amai^ 
cAy the Sea being probably fo impregnated with Salt, as not to imbibe 
more 5 which croffes another obfervation, that the nearer the 7>^?^ 
"fiques and the Line^^t Salter the Sea. 
As to the Colour of the Sea, I conceive there is as great variety m- 
it and its fteams, as in Gro^inds at Land 5 which may occafion the 
£cknefs in fome places more than in others : For the Sea fmclls diffe- 
rently in the Narrow and Main. And as to colour, it is of a Sea-green 
(and more fickly) in the Downs, than at Torhaj , and on Flymouth 
coaft more^ than paft ih^ Lmds-end 5 and in tbe Say of Bifcaj, than
