ABSTRACT OF PROCEEDINGS. lvii. 
function of the internal energy of the atom. We are also 
familiarizing ourselves with the idea that it is quite possible 
that the elements are mutually convertible. We have 
become familiar with the notion that the so-called Radium 
emanation passes over into Helium, and in recent papers 
by Ramsay and Cameron these authors consider that the 
effect of the action of emanation upon water and copper 
sulphate is to produce the gases Neon and perhaps Argon, 
whilst in the case of the action on copper sulphate the 
copper would appear to be degraded into lithium and sodium. 
In the case of the formation of Neon the authors consider 
it to be indisputably proved. In the other cases they are 
less certain. These modifications must not be regarded as 
upsetting or supplanting the atomic theory, but merely 
as rendering necessary some modification of our present 
conceptions of the atom: notably its invariability and 
indivisibility.
