it disappeared almost instantaneously, five or six minutes after the 

 termination of the earthquake. An engineer of the name of Chatil- 

 lon communicated to M. Hauy the following observation. He had 

 in his room a decanter half full of water, the inside of which, above 

 the water, had been covered with vapour, in consequence of the 

 lowering of the temperature during the night. This vapour had dis- 

 appeared in all the places which the water had touched during its 

 oscillations, and thus M. Chatillon was enabled to ascertain the direc- 

 tion as well as the magnitude of the oscillations which had taken 

 place in the water. He found that the axis of the oscillations had 

 never changed ; and that the direction of the oscillations was parallel 

 to a vertical plane, whose azimuth was 2 east of north, while he found 

 the variation of the needle 10 west. 



The following is an extract from the meteorological register kept 

 by M. Challaye, for the two days preceding and following the earth- 

 quake here described.

12. GEOGRAPHY OF SIBERIA. 



M. Hansteen has determined the longitude of the town of Yenisseisk 

 in Siberia, by astronomical observations, to be 92 10' 59" east of 

 Greenwich. He has connected, by the transposition of two chro- 

 nometers, other places with this town, and thus determined their 

 geographical position, of which we give the following ones : 



Places. Latitude. Longitude. 



Town of Yenisseisk . . 58 27' 19" 92 10' 59" East. 

 Mouth of the Elotchikha . 61 29 51 90 11
