90 MEMORIAL SKETCH.

 There his scientific imagination was kindled by the wonders 

 of the spectroscope in the laboratory of Professors Kirchhofif 

 and Bunsen ; and a supper-party in the Castle grounds, 

 given by them in his honour, stamped itself in his memory 

 as one of the happiest evenings of his life. At St. Moritz he

 Thomson, and made known two important discoveries, one 

 of which found immediate acceptance. But the other, re-

 without notice for many years ; and when, in 1875, he 

 stated his views more fully, they were strongly opposed

 gradually found acceptance, however, and were publicly 

 adopted by his chief opponent, but a few weeks after his 

 death, in 1885. 



But the joint work of the two friends on the Rosy 

 Feather-star was destined to bear yet more important
