closed waters at the bottom of old pits. We have altogether kept 

 out of view the experiments of Spasky and Kupfier on the artesian 

 wells of Vienna, as there is certainly some mistake, or rather, as 

 Professor Bischof remarks, some militating cause, and he conjectures 

 " that the depths of these springs are not equal to the lowest point of 

 the course of the spring, but that the springs rise from a still greater 

 depth."

32. Notice of remarkable Agitations of the Sea at the Sandxoich 

 Islands, on the 7th November, 1837; by T- Chas- Byde Rooke, F- 

 R. C. S. — On the evening and night of the 7th November, a most re- 

 markable commotion of the sea was witnessed at HanoJulu, in many 

 respects similar to that witnessed at these islands in May, 1819. One 

 inch and a half of rain had fallen during the previous twenty four 

 hours ; the wind was fresh from the N. E., squally at intervals. The 

 atmosphere was clear and cool. Therm. 74. 5 ; the barometer had 

 gradually fallen during the four previous days, but this evening had 

 again risen to 30.06, at six o'clock, when the alarm was given that 

 the sea was retiring. The first recession was the greatest, something 

 more than eight feet; but being unprepared to make observations at 

 the moment, the exact fall was not measured. The reefs surrounding 

 the harbor were left dry, and the fish aground were mostly dead.
