upon tiio oil difi'olvecl into a wonderfully fluid fubflancc. Tlie glafs 

 I then placed, where no duft could reach it, and, upon examining it the 

 ijext da}', I law fueh a inultitude of falts of different magnitudes dif- 

 perled about the oil, as it would almoft exceed belief to relate. Moll" 

 uf thel'e I'alts were pointed at each end, but many of them were i"o 

 niituite. that their figure could not be known or judged of, but by re- 

 ference to the larger oik^s adjoining to them. In fome of my obfer- 

 rations on this oil, I found the falts to appear in it, at the expiration 

 of only half an hour after it had been put into the glafs, and they 

 ijicreafed in number and fize every hour, the fmallcr growing larger, 

 and the oily liquor evaporating ; and I found that this fpecimen of 

 the Hop ])lant, contained twice as many falts as were in the former 

 cue. 



I obfer\ed one thing which feemed flrange to me, namely, that 

 many of thofe oblong falts which I had faid were pointed at both 

 vnds, did not extend in a ftraight lino, but were fomewhat bent or 

 doubled together ; but, whether thefe falts fo bent into a bow-like 

 figure, (.lo, for that reafon, excite the motion or fenfation in our 

 tongues, \\ hich we denominate bitter, I leave to be examined by 

 pthers.
