72 Stellar and Planetary Evolution. 



Illustrations of all the most powerful telescopes in the world, 

 past and present, were next shown, among which were 

 Herschel's great 40ft. telescope, the leviathan reflector of 

 Parsonstown (Earl of Rosse's), the Paris Observatory instru- 

 ments, the great Lick telescope on Mount Hamilton, California, 

 and the great Yerkes telescope, now the largest and most 

 powerful refractor telescope in the whole world. An example 

 was also shown of the obse^^7atory which has recently been 

 erected and equipped on the top of Mont Blanc, almost three 

 miles above the level of the sea. 



Mr. Jaffe — I have pleasure in asking this meeting to request 

 the Chairman to convey our thanks to Mr, Kelly for the excellent 

 lecture which he has given. The time and labour necessary to 

 collect such facts as he has put before us must have been enor- 

 mous ; but, as our chairman has remarked, the crowded state 

 of the house, and the close attention of the audience during the 

 entire lecture, will repay Mr. Kelly for the trouble he has taken. 

 He will probably excuse me if I indirectly convey our thanks 

 to another gentleman whose name he has mentioned several 

 times — Mr, Wilson. I am sure we all very much appreciate 

 having seen on the screen a direct copy of a negative taken in 

 a large telescope. There is a great difference in a lantern slide 

 taken from a direct negative and slides made from other negatives 

 which have^been multiplied. Another point which I should like 

 to mention is the desirability of universal time. Here we have 

 what is known as Belfast time, and I believe very few people know 

 what that really means. Our railways are worked according to 

 the so-called Dublin time, and our telegraphic system by Green- 

 wich. The western European time, as it is known, is used in Great 

 Britain but not in Ireland ; the central European time is used 

 by Germany, Austria, Hungary, Sweden, Italy, Bosnia, Servia, 

 and Turkey ; the East European time is used by Bulgaria and 

 Roumania. The other civilised countries, Norway, Portugal, 

 Russia, Switzerland, and Spain are using a fixed time of their 

 own. If the Council of this Society agree that we should 

 petition the Government on this subject, I am sure that the
