SERIO-COMIC VEKSE. 631 



" tell me, when along the line 



From my full heart the message flows, 

 What currents are induced in thine ? 

 One click from thee will end my woes." 



Through many an Ohm the Weber flew, 



And clicked this answer back to me, 

 " I am thy Farad, staunch * and true, 



Charged to a Volt with love for thee." 



LECTURES TO WOMEN ON PHYSICAL SCIENCE. 



PLACE. A small alcove with dark curtains. 



The Class consists of one member. 

 SUBJECT. Thomson's Mirror Galvanometer. 



THE lamp-light falls on blackened walls, 



And streams through narrow perforations, 

 The long beam trails o'er pasteboard scales, 



With slow-decaying oscillations. 

 Flow, current, flow, set the quick light-spot flying, 

 Flow current, answer light-spot, flashing, quivering, dying, 



look ! how queer ! how thin and clear, 

 And thinner, clearer, sharper growing 

 The gliding fire ! with central wire, 



The fine degrees distinctly showing. 

 Swing, magnet, swing, advancing and receding, 

 Swing magnet ! Answer dearest, What's your final reading ? 



love ! you fail to read the scale 

 Correct to tenths of a division. 

 To mirror heaven those eyes were given, 



And not for methods of precision. 

 Break contact, break, set the free light-spot flying ; 

 Break contact, rest thee, magnet, swinging, creeping, dying.
