is difcoYcrable in thefe Liquors, and therefore I (hall fay no 
more of them* Only I cannot omit mentioning one fort of 
Animal in them, which I never difcover'd till within thefe 
3 or 4 day«, and by reafon of their minutenefs may 
pofTibly have efcaped yoa alfo, Thefe are very flender long 
Worms, of which my Pepper-water is prodigroiifly full- 
They arc all oi the fame thicknefs, but their lengths are ve- 
ry different, fome being twice, and fome thrice as long as 
others, and at a Medium I judge the Proportion of therr 
length to their breadth at lc;^ft as 50 to i. Even to the 
largdt Magnifiers they look like Shreds of Horfe-hair (to a 
naked Eye) from a quarter to 3 quarcers of 'a^n Inch long. 
Upon a modefl Eftimate their thicknefs is not the looth 
pare of an hairs breadth, and confequently if you imagine 
an hair of your Head fplit into above 7800 equal Fibers, 
each Fiber would be as thick as one of thefe Creatures* 
Their Motion is equable and flow, and generally they wave 
their Bodies tut little in their Progreffion, tho' fometimes 
they make greater Undulations. But what is more remark- 
able, they fwim with the fame Facility both backward and 
forward, fo that ! cannot diftinguifh at which end the Head 
is, and I have feen the fame Worm go forward with one 
end, and back again with the other end foremofl: above to 
times together. And fometimes they will (like Leeches) 
fix one end on the glafi plate (on which I fay the Water) 
and move the loofe part of their Body found about very 
ocidly. Thefe I take leave to" call Capuhry Eels, and 1 have 
^given you as well as I coiiid a reprefentation of their Ap* 
pearai^ce ro a great Ma gnifierj in the feveral Poftnres I have 
f^en them fwim.. 
1 find the D ift of tlie BnttT^m ?idveriihntm or P^f-Ball 
to be the minuteft Powder th.^_t I ever faw : To a naked Eye 
you know (when 'tis crufh ct J it appears hke a Smoke or 
V^ipcur, and . vvi'th a common Microfcope you cannot 
diftinguifli the Particles. But when 'tis viewed with the 
grcat-wft magnifiers, each grain is vifible and exaftly alike,
