Notice of some Recent 



[Feb. 



that Marianini was not successful in any other cases, although 

 we are not informed how many patients were subjected to 

 the same method of cure. Let it be borne in mind, how- 

 ever, that if by the application of the electric influence, 

 even five out of a thousand of our fellow creatures can be 

 restored to health, from helplessness and misery, the physi- 

 cian is not justified in withholding the. assistance of such a 

 powerful agent. 



M. Matteuci # in examining the pneumogastric nerves, 

 could observe no current in them. He concludes that some 

 foreign agency was interposed when any developement was 

 exhibited, and that although, in all probability, the secre- 

 tions depend upon the presence of opposite electrical states 

 in the hearing organs, no means have yet been devised for 

 appreciating their existence. 



III. MAGNETISM. 



Declination of the Magnetic Needle. — The mean oscillation 

 or difference between the easterly position of the magnet 

 in the morning, and its western direction in the afternoon, 

 at Frieberg, is exhibited in the following table, according 

 to H. W. Dove. (Poggen. Ann. xxxi.) 



The mean oscillation for March, June, September, and 

 December, is 9' 51''-8. The regular increase from the cold 

 to the warm months is very distinct. 



The removal of the extreme of the magnetic meridian 

 and its position, is as follows : 



March . . 

 May . . . 

 June . . . 

 August . 

 September 

 November 

 December
