* Tait finds for fresh water the value .0072 (i — o.o34/>) and for sea water .00666 (i — 0.034/) where/ is the pres- 

 sure in tons per square inch. The range of variation of / was from i to 3 tons. 



t Rontgen and Schneider by piezometric experiments obtained 5.0 X 10-" for rock salt and 5.6 X lo-" for sylvine 

 (Wied. Ann., vol. 31).
