468 michelson's recent researches on light. 



We may thank Professor Micbelson not only for what he has estab- 

 lished, but also for what he has unsettled. In his various researches, 

 which I have hastily sketched, but which require diagrams or models 

 to be clearly understood, he has disphiyed liigh intelligence, great ex- 

 perimental skill and ingenuity, and untlagging perseverance. With a 

 full api^reciation of his work, the Eumford Committee recommended, 

 and the Academy voted, that the Kumford Premium be awarded to him.
