THE SPEED THEORY. 
Raptum, discovered by Madam Curie, is a great aid to the 
solution of the Riddle of the Universe. 
One of the greatest generalisations of science (termed the 
conservation of energy) teaches that energy, however it may 
be changed from one form of force into another, is never 
destroyed or originated. 
Another great generalisation (the persistence of matter) 
teaches that no substance comes into existence out of nothing, 
and no substance is ever annihilated. 
Both of these great laws Radium, on its first discovery, 
appeared to contradict, by, apparently, continuously 
throwing off heat, or energy, without getting colder, although 
the dissipated energy was not replaced from external 
sources; and it appeared to continuously emanate matter 
from itself without growing less. 
This extraordinary behaviour naturally excited great 
interest in scientific minds, and set the experimenters at 
work. Among that able and learned band of men Professors 
Rutherford and Soddy devoted their attention to the study 
of Radium and kindred radio-active substances. After most 
painstaking and ingenious researches, they were rewarded 
by being able to devise and publish an explanation showing 
that Radium, like other substances, confirmed the great 
theories of the conservation of energy and the persistence of 
matter. 
*The explanation was that some of the atoms of Radium 
were constantly disintegrating into smaller portions of 
*Dr. W. Hampson’s “ Radium explained.”
