30 Recent Advances in Electricity. 



virtue of known properties, directly deducible from Newton's 

 three laws of motion, and roughly illustrated by smoke-rings, 

 spinning tops, and gyrostats, will, when properly looped 

 together and interlaced, give us a variety of structures 

 corresponding to the different kinds of matter. One of the 

 latest and most elaborate attempts to devise a structure for the 

 ether has been recently published in the Phil. Trans, by our 

 fellow townsman. Professor Larmor, under the title "A dyna- 

 mical theory of the electric and luminiferous medium." Much 

 yet remains to be done before any such theory can be said to be 

 established, or even to have met with very wide acceptance. 



Professor Redfern, in moving a vote of thanks to the 

 lecturer, expressed regret at Professor Everett's withdrawal from 

 the Queen's College, and hoped that it would not mean his 

 withdrawal from the neighbourhood of Belfast. 



Mr. J. Brown seconded. He remarked that the discovery 

 of the Rontgen rays, though " made in Germany," had very 

 narrowly missed being made in Ireland, Professor George 

 FitzGerald, of Dublin, brother of their ex-president, having 

 twelve years ago expressed the belief that, under certain con- 

 ditions, the effect could be obtained. 



The vote of thanks was passed unanimously. 



Professor Everett having replied, 



The proceedings then terminated.
