North, fometimes to the South, ten, twelve, fourteen 

 times a day, with the rapidity of a torrent. Thefe 

 multiplied, and, very frequently, unequal move- 

 ments, cannot poffibly be referred to the tides of the 

 Ocean, which are fcarcely perceptible in the Me- 

 diterranean. A Jefuit quoted by Spon *, endea- 

 vours to reconcile thefe to the phafesof the Moon; 

 but fuppofing the table of them, which he pro- 

 duces, to be accurate, their regularity and irregu- 

 larity will always remain a difficulty of no eafy fo- 

 iution. He refutes Seneca, the Tragic Poet, vvho 

 afcribes to the Euripus but feven fluxes, in the 

 day time only : 



Dùm lafla Titan mergat Oceano juga. 

 Till Titan's tired fteeds in th' Ocean plunge. 



He adds farther, I know not after whom, that in 

 the Sea of Perfia the flux never takes place but in 

 the night-time ; and that under the Arcftic Pole, 

 on the contrary, it is perceptible twice in the day- 

 time, without being ever obferved in the night. It 

 is not fo, fays he, with the Euripus. 



I (hall obfcrve, by the way, that his remark 

 with refpect to the Pole, fuppofing it true, evinces 

 that it's two diurnal fluxes are the effecfls of the
