Man oi Xetters^, we chanced among other things, to 
talk of this Liquor. And tho' it were fcarce to be 
hop d, that it could ftill retain any of its motive Ver- 
tue, yet. lo gratify his Curiofity, and that of fome in- 
genious men there prelent, I caufed the Vial to be 
brought, and having unftopt it, I pourd out the Li-, 
quor into a conveniently fhaped VefTel; in which after 
we had fuffered it to reft a while, they were delight- 
fully furprized to fee it move (tho* not in my opinion 
quite fo briskly as before, yet^ very manifeftly and va- 
rioufly. This incouraged me to think it poffible, that 
it might retain fome motion, tho' but languid, 7 or 
8 weeks afcer; and therefore on the 2 of I lookd 
upon it again and having caufed it to be pour d into 
a China Cup, it manifefted at firft a brisk and various 
motion. But this afcer a while did fo flacken, that I 
began to have fome fufpicion, that the motion it was 
put into by Effufion, and the firft contad: of the Jiry 
might have given it the greateft part of its agitation. 
But this being but fufpicion, I put the Veffel into di- 
vers poftures in a Window, the better to difcover the 
true caufe of this ?bcsnomenon : but whilft I was bufy 
about this , which ingrofTed my attention; a mifchance 
overturned the Cup, and, by throwing down the Li- 
quor, put an end to my fpeculation. Yet this mif- 
chance hindred me but from obferving, how long the 
odd agitation of our Liquor would have continued, 
but not from fiading that it lafte4 a great while. For 
I fliewed it the Forreign M^///^r about or after the be- 
ginning of J^;?^, that i§, about five months, or more, 
after the Liquor -was firft obferved to move.
