Now the concept of personality, as woven around a system of chemical reflexes, handed on from generation to generation, is bound to change all that, and to create a structure of positive eugenics. It has been said that what radium is to chemistry, the internal secretions are to physiology.

The phenomena of radioactivity were discovered accidentally in 1896 by the French chemist Becquerel. Many investigators immediately began working along this promising line, and two years later Madam Curie, in association with others, discovered the new element radium.

When we come to deal with a new problem we have really no right to show ourselves more exacting; yet there are found persons who refuse to admit the hypothesis of the atomic disaggregation of radium because they cannot have set before them a detailed plan of that complex whole known to us as an atom.

In the case of central tumours the shell of bone is removed over an area sufficient to allow of the enucleation of the tumour, or the affected portion of bone is resected. Should there be evidence of malignancy, such as increased rate of growth, a tube of radium should be inserted, and in advanced cases with destruction of tissue, amputation may be called for.

It has a well-marked and characteristic spectrum, and there is no reason to suppose that it is not an element in the ordinarily accepted sense of the term."*7* In 1903 Messrs. Curie and Laborde*8* made the remarkable announcement that a crystal of radium is persistently warmer than its surrounding medium; in other words, that it is perpetually giving out heat without apparently becoming cooler.

Perhaps they would not have gone then had not the band begun to play to announce new arrivals; but before they left the great Throne-Room King Evardo added to Ozma's birthday presents a diadem of diamonds set in radium. The next comer proved to be King Renard of Foxville; or King Dox, as he preferred to be called.

When you discovered radium, we realized that this would eventually lead to the discovery of the higher power, but we feared that this might not be for hundreds of years. "That communication was possible through the medium of radium and electricity, we were totally ignorant of.

"Just what is it," said the Great Scientist, "that you want to know?" "Professor," we answered, "what our journal wants is a plain and simple explanation, so clear that even our readers can understand it, of the new scientific discoveries in radium. We understand that you possess, more than any other man, the gift of clear and lucid thought " The Professor nodded.

There are no more continents to discover; but by the time overshoes are out of date and the poll has developed into an income tax, the other half will be paralleling the canals of Mars with radium railways. Fortune, Chance, and Adventure are given as synonymous in the dictionaries. To the knowing each has a different meaning. Fortune is a prize to be won. Adventure is the road to it.

Sir W. Ramsay and Professor Soddy attained a like result by endeavouring to estimate the mass of the emanation by the quantity of helium produced. He also remarks on "the experimental difficulty of accurately determining the number of alpha particles expelled from radium per second."
