488 AJlronomy. — Galvanifm. — l^ew Species df Inoculation* 



ASTRONOMY. 



In our laft we prcfentctl our readers with tables containing 

 the geocentric motion of the two new planets, Ceres Fercii- 

 nandea and Pallas, for the month of April ; we now fubjoin 

 tables of .their motion calculated for the month of May 1803. 



GALVANISM. 



ProfeflTor Aldini, when on his way to France, made the 

 following experiment at Calais :— He extended a wire from 

 the top "of the Weft Jetty to Fort Rouge, dirtant about 160 

 feet, and which are feparated by an arm of the f^a. The 

 extremity of this wire towards the jetty was inmierfed in the 

 water, the other extremity was fixed to a niaft, and a portion 

 of the wire was free. A fecond wire was difpofed in fuch a 

 manner, that us lower extremity was immerfed in the water 

 at the bottom of the mall, while its upper extremity could be 

 made to communicate with the wire fixed to the maft. Be- 

 tween the extremity of the wire attached to the iWaft and that 

 of the fetond wire immerfed in the fea the profefTor placed 

 an animal, as a prepared frog for example, which being then 

 brought into contaft with the two wires, immediately expe- 

 rienced the ui'ual contractions. The (ea water, therefore, 

 fcrved as a conduilor between the other extremities of the 

 wires. 



A NEW SPECIES OF INOCULATION. 



Accounts have been received from one of the travellers in 

 Africa (Hornemann, we believe), ftating, that in a diftri6l 

 which he has vifiied he found a kind ot inoculation praftiled, 

 which anfwers the fime end rcfpeding fyphilis that the vac- 

 cine pock does refpecling the fmall-po.x — exempting the pa- 

 tient from the poffibility of iofedion.
