(1696) Marigold leaves brought to me from my cellar , which vinegar has been preserved in a bottle for more than twenty - five years and is uncommonly strong .With the said Vinegar I also mixed some of the said percolated liquid , otherwise called rennet , and when I again had allowed it to stand for some time , I could detect no salt particles in the vinegar , but when this liquid mixture had stood for eighteen hours , I did see a few crystallized salt particles .Hereupon I took ordinary French wine and also Vinegar , and I put each of them separately , in order that the liquid might evaporate somewhat from them and the salt particles might crystallize , and I discovered both in the wine and in the Vinegar a large number of salt particles very closely resembling the salt particles previously found by me in the wine as well as in the vinegar .
