only one case in ten did it fail to give relief, and in n^ost cases it 

 was permanent. In galvaiiizina: patients it was from five to ten 

 minutes before they found their breathing relieved. He still used 

 plates of Oiilv four iiiches square ; began with only a few, and some- 

 times extended them to thirty. The conducting wires were ap- 

 plied to pieces of tinfoil placed on the nape of the neck and at the 

 pit of the stomach, or rather lower, and he recoiiimended the 

 points of the wires to be moved a little on the tinfoil. He found 

 that all patients could bear a greater power at first, than after 

 thev had been galvanized several times. Dr. W. assigned no 

 reason for this fact; but it is evidently owing to the galvanic 

 fluid blistering the skin on those parts, and thereby increasing 

 their conducting powers, and at the same time augmenting their 

 sensibility. In some habits it produces inflammation, and ulcers 

 which continue open several weeks. 



BELFAST ACADEMICAL INSTITaTJON. 



Tuesdav, the 22d of October, an election for a Professor of 

 Natural Philosophy came on in this Institution, when a number 

 of gentlemen of high respectability and attainments offered

 tleman most capable of the appointment. After full deliiteration, 

 the electors proceeded to the ballot, when Mr. Knight of Aber- 

 deen was found to have the greater part of the votes ; and we 

 have no doubt, from what we have heard, that he will do honour 

 to himself and to the Institution which has chosen him to the 

 important charge.
