VOL. XV.] PHILOSOPHICAL TRANSACTIONS. 149 



In contemplating some large flat particles, as also some sharp ones, which 

 were imperfect, I was confirmed in the make of those bodies, namely, that all 

 the sharp salt particles in wine and vinegar, how small soever they are, had at 

 first flat thin bodies, which by being rolled up at the four corners, make the 

 salts above described. 



Having set some Mosel wine for a few hours uncovered on the table, I then 

 saw swimming in it divers figures of salt, such as I had formerly seen in other 

 wine and vinegar ; but with this difference, that in many of them I could not 

 only perceive a thickness and a hollowness, but also distinguish that each of 

 them consisted of 7, 8, 9, or 10 plates, lying over one another, as here N° 4, 

 fig. A. I saw also several figures, out of the top of which other half figures 

 appeared, as fig. B. There was something like this in the Orleans wine, but 

 not near so much as here. I saw also several salts, which had other particles 

 thrust through them, as fig. C. There were also some flat figures, whose sides 

 were rolled up, as fig. D. And some whose shorter sides were indented, as 

 fig. E. Some appeared like half of A, as fig. F. A few others had their ends 

 blunt, as G. 



I observed in good Hock wine, of a year old, after it had stood 3 hours un- 

 covered, that there were salt particles in it, which were sharp at both ends, 

 having a height, or ridge upon them, like the sharp bottom of a boat turned 

 upside down, though they were otherwise diaphanous, as N° 5, fig. A. Such 

 a kind of figure has appeared in French wine ; but when I let this wine stand 

 for two days and nights, some of the salt figures were larger, having several 

 circumferences, some 2, 3, 4, and others so many that they could not be 

 counted, as they lay close together, some were so beautiful that no sea pro- 

 duction, whether coral or shells, might be compared to them. As in fig. B. 

 Some figures were blunt at both ends, and sometimes one end more than 

 another, as fig. C. In another place I saw swimming in the wine, salts which 

 had not only several circumferences, but steps or wrinkles across, as at D. 

 Some little particles, of different sizes, resembled wine casks, as E. In ob- 

 serving some places, where the thinner part of the wine was evaporated away, 

 I found several figures like branches, seeming to proceed from one salt particle ; 

 in viewing them exactly, I saw that the branches consisted of nothing but 

 very small salts joined together, some whereof were very regular, and the 

 largest were placed at the end of the branches; as at FGHI. 



In Hock wine, 6 years old, I found at first very few salt particles ; but after 

 standing 3 or 4 days, there were many more, though in much less numbers, 

 than in the same wine that was but of a year old. But I am persuaded that 

 the largest of these consisted each of above 100 small ones, compacted together.
