538 Lord Mayleigh on Argon. [April 5, 



Rucker on the life and work of the illustrious Helmholtz. It will be 

 known to many that during the last few months of his life Helm- 

 holtz lay prostrate in a semi-paralysed condition, forgetful of many 

 things, but still retaining a keen interest in science. Some little 

 while after his death we had a letter from his widow, in which she 

 described how interested he had been in our preliminary announce- 

 ment at Oxford upon this subject, and how he desired the account of 

 it to be read to him over again. He added the remark, " I always 

 thought that there must be something more in the atmosphere."
