ing and intermitting of this for the Flux of the fott 
xner, and the long Stop in this, whilft the great Refer- 
voir is filling, for thePaufe or Intermillion of the for- 
mer. Befides which, we muft remark,, that as the 
Flux in the former Fountains may be changed, and be 
made longer or flatter; fo in this, the Number of 
Intermiflions during one Fit of flowing and intermit- 
ting may not always be the fame, becaufe of the dif- 
ferent Capacities of the two Refervoirs, and a Differ- 
ence or Change occafioned in the Feeding-Stream at O. 
For if, whilft the great Refervoir A B C D is emptying, 
the little Refervoir EFGH fiould empty itfelf nine 
times, for Inftance, and be half full again, the Foun- 
tain derived from its Syphon STV muft have nine 
Intermiflions in one Fit, and ten in another, alternate- 
ly, whilft the Feeding-Stream at O remains the fame. 
But the Feeding-Stream at O being leflened or enlarg- 
ed, without making the Syphon MNP run continu- 
ally, the Number of Intermiflions in each Fit will be 
diminilhed or augmented accordingly. But *tis pecu- 
liar to this laft Sort of Fountains, that in each Fit of 
flowing and intermitting, the firft Flux will be larger 
and longer than the fecond, and the fecond than the 
third j but the firft Intermiflidn will be (hotter 
than the fecond, and the fecond than the third : 
becaufe the Syphon MNP running fafter at firft 
than at laft, the Refervoir EFGH muft be a (hotter 
Time in being filled, and a longer Time in be- 
ing emptied the firft Time than the fecond ; 
the fecond than the third, and fo on. As to the 
whole Time of the firft Flux and Intermiflion,inCom- 
parifon of the whole Time of the fecond Flux and 
Intermiflion, it is a Particular, requiringfo many Things 
to be taken into Confideration, for determining it in 
each
