may not be fo fenfibly perceived on the folic] as the fluid 
parts of this Terraqueous Globe. That I might in the 
beft way I could think of, make fome tryal towards a 
difcovery of the Truth herein, I took this Method. 
Firft, I divided the Nt^B^gw into four Senaries of 
Hours : The firft confuted of three Hours before the 
Southing of the Moon, and three after the fecond of the 
fix hours following, and fo the third and fourth contain- 
ed the two remaining Quarters of the Natural day. I 
next betook my felf to obferve Births and Deaths, in otir 
own kind, as a!fb in other Species of Animals, whether 
they fell out indifferently in any of thefe four Senaries : 
And I found none that were born or died a natural Death 
in the firft and third Senaries, which I tike liberty to call 
firft and fecond Tides, but everyone either in the (econd 
or fourth Senaries, which I call firft and fecond Ebbs. I 
then proceeded to make Obfervations in the Motions of 
Difeafes, which I could the better do, becaufe I had 
fome in my Family vifited with Agues. Here I found 
that the tumult of the Fits generally lafted all the Tiding 
time, and then went off in gentle kindly Sweats in the 
Ebbs. I went on then to take notice of the Sex res 
non nat urates, and alterations of the Weather, and fuch 
Accounts as I could meek with of Earthquakes and fun- 
dry other things : And I have yet met nothing to hinder 
me from laying down this as a Maxim, That Motion, Vi- 
gour, A&ion, Strength, ©c. appear moft and do beft in 
the Tiding Senar ie s ; and that Reft^ Relaxation, Denay, 
Dissolution belong to the Elling Senaries.
