other to the vertex of the magnet. On completing the ch-cuit of the 

 calorimotor thus connected with the magnet, the weight fell off; I 

 found, however, that although the power of the magnet was enfee- 

 bled, it was not destroyed, as in despite of the torrent from the calo- 

 rimotor, it held, as nearly as I could judge, about half as much as 

 before. 



I have ascertained that when the poles of the galvanic magnet, 

 while excited, are brought into contact with mercury, communicating 

 with one pole of the calorimotor, above mentioned, the vertex of the 

 magnet being in contact with the other pole, a gyratory or whirling 

 motion may be observed in the mercury.
