V* ^drt of a Letter from Mr Anthony van Leu wen- 
hoek, F. <^ S. giy'mg his Ohferydt'ms on the late 
\ Storm. 
Delft, Jan. 8. 1704. N. S. 
I Affirmed in ray Letter of the ^d otNommberUk pa&^ 
that Water may befodafhd and beaten againft the 
Banks and Dikes by a ftrong Wind, and divided into 
fuch fmall Particles, as to be carried far up into the Land* 
Upon the 8th of DecerAer^ijo^. N.S. We had a dread- 
ful Storm from the South Weft, infomuch, that the Water 
mingled with fraall partsof Chalk and Stone^ was fodallit 
againft the Glafi windows, that many of them were dark- 
ned therewith^ and the lower Windows of my Houfe, 
which are made of very fine GlaiS, and always Icept well 
fcowex'dj and were not open'd till 8 a Clock that Morn- 
ing, notwithftanding that they look to the North Eaft, 
and confequenily ftood from the Wind 3 and moreover, 
were guarded from the Rain by a kind of Shelf or Pent- 
houfe over them 5 were yet fo covered with the Particles 
of the Water which the Whirl-wind caft agdnft them, 
that in- lefi than hdf ao hour they were. deprived of nioft 
of their tranlparency,, and, forafoiiich as thefe Particles- 
Water were not'qmt^^ exhakd. I concluded that it 
• moft be Sea water, -which the (aid Storm had not-CBly 
d^Oit ag;;-' ' Windows, but Ipread alfo over ilie 
whole Gc> , . _
