SGIENGK 



4S3- 



versity of Sydney, has invented an artificial 

 larynx for a man who had lost his voice. 

 The invention is a singular success. The 

 changing of certain reeds contained in the 

 instrument makes the voice soprano, tenor, 

 contralto or bass, at will.

Peofessok Eli Whitney Blake, who 

 until last June filled the position of Hazard 

 professor of physics in Brown University, 

 died on October 1st, at the age of 59 years. 

 The following particulars concerning his 

 life are taken from the Boston Transcript. 

 Professor Blake was born in New Haven, 

 his father being the well-known inventor of 

 the same name. He was graduated at Yale 

 University in 1857, studied chemistry and 

 physics in the universities of Heidelbei'g, 

 Marburg and Berlin, and returning to this 

 country was named professor of chemistry 

 and physics in the University of Vermont 

 and the State Agricultural College. He 

 was then appointed professor of physics and 

 mechanic arts at Cornell University ; later 

 he became acting professor of physics at 

 Columbia College, and from 1870 until last 

 June filled the chair of physics at Brown 

 University. 



The following lines (we do not know at 

 whose instance) have been engraved upon 

 Huxley's tombstone: 



"And if there be no meeting past tlie grave, 

 If all is darkness, silence, yet 'tis rest. 



Be not afraid, ye waiting hearts that Tveep! 



For God "still givetli his beloved sleep.' 

 And if an endless sleep he wills, so best!" 



Dr. Elliot Folger Eogees, instructor

 fessor in the medical faculty of the Univer- 

 sity of Berlin, died recently at the age of

The German correspondent of the N". Y. 

 Evening Post writes that Professor H. Kay- 

 ser, Director of the Physical Institute in 

 Bonn, has demonstrated that helium (as 

 well as argon) exists in a free condition in 

 nature. The waters of AVildbad, in the 

 Black Forest, for instance, contain in the 

 bubbles of gas rising continually to the sur- 

 face (about 96 per cent, nitrogen), both 

 those elements which on bursting escape 

 into the surrounding atmosphere. Even in 

 the natural air in Bonn, Professor Kayser 

 found helium in a free state, but, as the 

 spectroscope showed, in infinitesimal quan- 

 tities. *

 cival Lowell's articles on 'The Planet 

 Mars,' reprinted from the Atlantic Monthly.
