DE LUe'a ELECTRIC COLUMN. 



N our last nunibcF (p. 317)^ by a typographical omission 

 we slated that " since that time (viz. '2.Mh Marcli) ihejf- 

 (the hells) have been known once to cea-ie ringing.'^ — The: 

 sentence should have read '* since thai lime they have 720^ 

 been known once to cease ringing.'' 



We have since received notice, that on the 21st oF May 

 the small bells connected with Dc Luc's electric column 

 were still ringing, and it was supposed had continued so 

 without intermission since the ^25lh of March^ 



We are also desired to request that those of our readers 

 who may have constructed cokuims of the kind alluded to, 

 will f&vouF us with such observations upon them as ihey^ 

 may make from time to time.
