flow at Grenelle when the water of the Passy well by — false con- 
siderably above the level of the earth shall again reéstablish the pressure. 
It appears impossible to foresee what may be the final result of this 0 
ration. Mr. Kind’s method of boring perfectly met what was fstendd 
and the well had reached at the end of two years and three months 528

water sheet is pierced 23 metres lower down than at the well of 
Grenelle—the latter being 547 metres absolute depth, and 511 m. below 
sea level; the well at Passy the orifice of which is 16™-5 higher has an 
actual depth o of 588 m. or 533 m. beneath sea sree _ The temperature 
of the water is the same in both wells =28° C. o 4 Fh. 
It is easy to see that the third question—what ie is it 
new experiment of the same kind ?—leaves an ample field for Facade
