152 PHILOSOPHICAL TRANSACTIONS. [anNO 1685. 



much larger than in the Coteau and fine Tonsain wine; and had the shape of 

 A, B, D, G, in N' 9. 



I took. Rhenish wine tartar, beaten very small, and put it in fair rain-water, 

 and when the water was settled, I saw in it many such figures as in the wine 

 itself, viz. some which were very clear, and had two sharp ends, as N° 9, fig. L. 

 But the most of them were very irregular, probably because no sweet or oily 

 matter was mixed with them. 



I took the tartar of French wine, and examining it in the same manner as 

 the former, I found some salts, which agreed perfectly with those in the wine ; 

 but the rest of them were more irregular than in the tartar of rhenish wine. 



I took Orleans wine, pure as it came out of the vessel, and put into every 

 drop a piece of crab's eye, as broad as the knife, and when it had stood 3 

 hours I could find no such salt in it as I had seen in the wine that had no crabs* 

 eyes. But there were many salts, whose basis were an oblong square, and the 

 sides rose up pyramidal. Other salts were flat, as N° 10, fig. A; others were 

 six sided, as fig. B ; others had two slanting sides, as fig. C ; some few quadri- 

 laterals had four sided figures within them, as D ; others again had the shortest 

 sides something irregular. Some salts were like fig. E. In these last I could 

 perceive no rising, perhaps because they were very small. 



I likewise took wine, and put white chalk into it, in the same quantity as 

 before, letting it stand about a quarter of an hour before I observed it, and 

 then I found a great number of the salts; but they were not so large as those in 

 the wine mixed with crabs' eyes ; but when this wine and chalk had stood about 

 12 or 14 hours, I saw the salts not only larger, but the pipes likewise in several 

 places rose from a point of chalk, in great quantities, as above in N° 10, fig. F. 

 These pipes also were larger than the others, though they differed sometimes 

 in size among themselves. 



I put into Rinco wine, some pieces of crabs' eyes, and after 12 or 15 minutes, 

 discovered a few salts in it ; but when the wine had rested some hours, I found 

 in it a very great number of figures, as N 10, ABCDEF, the salt figures first 

 discovered, were now grown large, though none of them were like the salts in 

 rinco wine, which had no crabs' eyes in it. 



P.S. Since the writing of this letter, I have opened a bitch, and found in the 

 womb, or rather in both the tubes, a great quantity of the male seed of a dog, 

 concerning which I shall enlarge in my next.
