Now this Jdr^/jJ?re/^/ motion, if noihingelfe were fuperadded 
to the Annual^ would give us two Tides in a moneth, and no 
more ; ( the one upop, the Acce;ktation,' the other on the Re- 
tardation at NeWAlP0Qn apd :lull-moon s and two Ebbs, at 
the two Ci£arters 5 and in the iMtrvals, Rifing and Falling
