Electric Column . — Lectures, 3 1 7 



DE LUC'S ELECTRIC COLUMN. 



We have again to notice the ringing of the small bells by 

 means of De Luc's electric column. They were ringing on 

 the evening of the 24th of August, and had been so doing, 

 without being observed to have stopped, for a period of 152 

 days and a half. This long continuance renders it not im- 

 probable that (as was suggested in our Magazine for March) 

 u the weight of the clapper may be so adapted to the power 

 of the apparatus, as to cause small bells to continue ringing 

 for several "years without intermission. " 



If any of our mechanical readers can suggest to us an 

 easy method, by which a pendulum vibrating can give mo- 

 tion to wheel-work, they are requested to communicate such 

 contrivance to us. It is much wished that an instrument 

 may be made, which by the motion of an index hand and 

 dial-plate may show the number of vibrations in a given 

 time, as it would be very interesting to observe what altera- 

 tions may take place in different states of the atmosphere.
