Flux and Re flux of the Sea, and heard of another, nolefs re-

Upon the IVefi fide or the Lono^ IJland, the Tides, which came 
from the South^wefl, run along the Coaft, Northward fo that 
during the ordinary courfe of ihe Tides, the Flood runs Ea^ in 
the Frith, where Berneray lyes, and the Ebb Wefi. And thus the 
Sea ebbs and flows orderly, feme 4, days before the full Moen^ 
and change^ and as long afrer (the ordinary Spring-tides rifing 
fome 14. or i j, foot upright, and all the reftproportionably, as
