FLU 
tion of the bodies themfelves : which is rendered farther 
probable from confidering that the natural ftate of bodies 
in this refpedt i| changed by certain mixtures; thus, 
when two metals are compounded, the mixture is com¬ 
monly more tufible than either of them feparately. 
Newton’s idea ot the eaufe of fluidity is different : be 
makc-s it to be the great principle of attraction. The 
various imeftine motion and agitation among the par¬ 
ticles of Raid bodies, he thinks is naturally accounted 
for, by firppofing it a primary law of nature, that as all 
the particles of matter attract each other when within 
•a certain diftance; fo at ail greater distances, they avoid 
and tiy from one another. For then, though their com¬ 
mon gravity, together with the preffure of other bodies 
upon them, may keep them together in a mafs, yet their 
continual endeavour to avoid one another fingly, and the 
adventitious impulfes of heat and light, or other external 
cattles, may make the particles -of fluids continually 
move round about one another, and fo produce this 
quality. As, therefore, the eaufe of cohefion of the 
parts of folid bodies appears to be their mutual attraction; 
5 b, on this principle, the chief eaufe of fluidity feems to 
Tie a contrary motion, impreffed on the particles of fl uids ; 
by which they avoid and fly from one another, as foon as 
they come at, and as long as they keep at, fuch a diftance 
from each other. It is obferved alfo in all fluids, that 
the direction of their preffure againft the veflels which 
contain them, is in lines perpendicular to the Tides of fuch 
veflels ; which property, being the neceflary refult of the 
ipherical figure of the particles of any fluid, lliews that 
tire parts of all fluids are fo, or of a figure very nearly 
approaching to it. 
FLU'IDNESS, yi That quality in bodies oppofite to 
liability.—What if we ftiould fay that Jluidnefs and liability 
depend fo much upon the texture of the parts, that, by 
the change of that texture, the fame parts may be made 
to conftitute either a fluid ora dry body, and that perma¬ 
nently too ? Boyle.

FLU'OR SPAR, a mineral of many different colours,

colourlefs, more or lefs tranfparent, and ferving as the 
matrix for the ores it envelopes. Its figure, when regu¬

FLUSIFING, or Vi.issengen, or Flessingue, a fea- 
port town of the Batavian or Dutch State of Zealand, in 
the ifle of Walcheren, on the north fide of an arm of the 
Scheldt, and defends the paffage not of that river only, 
but all the iflands of Zealand, of which it is one of the 
mod important keys ; it was on this account that Charles 
V. when he abdicated his crown, particularly enjoined 
his fon, Philip, to take care and preferve it fafe : and 
that prince, when he left the port, in 1559, to take pof- 
feflion of the kingdom of Spain, commanded a cattle to 
be built to defend the town, which was however never 
executed, on account of the troubles that happened foon 
after. The port lies between two moles that break the 
waves of the fea, which enters the town by means of two 
canals, forming two bafons, fo that loaded veflels may 
fail into the town, to the great convenience of the mer¬ 
chants. It was but a fmall place before the fifteenth cen¬ 
tury, when Adolphus de-Bourgogne birrounded it with 
walls ; fince which it has become a celebrated port, and 
is now, next to Middleburg, the richeft town in the pro¬ 
vince of Zealand. The emperor, Charles V. erected it 
into a marquifate in 1551, which the prince of Orange pur- 
chafed, together with the marquifate of Ter-Vere, for 
146,000 florins. The ftadthoufe, built according to the 
model of that at Amfterdam, is a fuperb edifice, and well 
deferves the attention of travellers. The inhabitants of 
Sluys pillaged this town in 1485. The ftates-general 
feized it on the 27th of April, 1573, by means of (even 
boats filled with foldiers, fent by the prince of Orange 
from
