Prof. Trego announced the decease of the Hon. Louis 

 M'Lane, a member of this Society, who died at Baltimore, on 

 the 7th instant, aged 72. 



Dr. R. E. Rogers made a communication on the mode of se- 

 curing more certain and effectual results from the operation of 

 electrical machines; and laid before the Society a drawing of 

 a machine of his own invention, which he believes will ope- 

 rate much more eflfectuall}^ than the machines in ordinary use; 

 the peculiar feature being the rapid motion given to the rub- 

 bers and the points, instead of the plate or the cylinder, as in 

 common electrical machines. 



The Society then proceeded to the stated business of the 

 meeting, the balloting for candidates for membership. 



Prof. Trego, reporter for the Proceedings of the Society, 

 laid upon the table No. 57, published since the last meeting. 



All other business having been concluded, the ballot box 

 was opened by the presiding officer, and Capt. Andrew A. 

 Humphreys, of the U. S. Topographical Engineers, was de- 

 clared to be duly elected a member of the Society.
