According to the Jirfi of thefecaufes 5 we fliould have the 
longefl natural daies in December^ and the Ihprteft in June^vvhich 
U it did operate alone, would give us at thofe^tinjes two 
High- waters. mh 
According to the fecond caufe,if operating fingly, wc fliould 
have the longeft daies at the two Solftices in June and December^ 
and the two fliorteft at the JSquinoxes in M ar eb Q,nd Septem- 
ber > which would at thofe times give occalion of -four ^mual 
High-waters. 
But the true of the Natural Days, arifing from a 
'Complication of thofe two caufej^ fometinies crofling and fome- 
times promoting each other:though we (hould find foi^e increa- 
fes or dccreafes of the Natural daies at all thofe feafqnsanfwe- 
rable'to the refpe^livecaufes (and perhaps of Tides proportio- 
nably thereunto : ) yet the longeft and Ihorteft natural daies 
abfolutely of the whole year (arifing from this complication of 
Caufes ) are about thofe times of Allhallonidde andXandlemai y 
(or not far from them ) about which thofe Annual High-tides 
are found to be : As will appear by the Tables of ^Equation of 
TV^i^ar^i/ daies. And th«rcforcl think, we may with very good 
reafon caft this Period upon that caufe, or rather com-
