Important experiments on the susceptibility of oxygen at different pressures and temperatures were carried out by P. Curie (C.R.
For air Curie calculated that the susceptibility per unit mass was Io 6 K= 7830/0; or, taking the mass of 1 c.c. of air at o° C. and 760 mm.
The magnetic properties of the metal at different temperatures and in fields up to 1350 units have been studied by P. Curie (loc. cit.), who found that its " specific susceptibility " (K) was independent of the strength of the field, but decreased with rise of temperature up to the melting-point, 273° C. His results appear to show the relation - K X10 6 = I'381 - O'o0155t°.
Curie has shown, for many paramagnetic bodies, that the specific susceptibility K is inversely proportional to the absolute temperature 0.

PIERRE CURIE (1859-1906), French physicist, was born in Paris on the 15th of May 1859, and was educated at the Sorbonne, where he subsequently became professor of physics.
And Mme Curie subjected a large amount of pitchblende to a laborious process of fractionation, with the result that in 1898 they announced the existence in it of two highly radioactive substances, polonium and radium.
Professor Curie, who was elected to the Academy of Sciences in 1905, was run over by a dray and killed instantly in Paris on the 19th of April 1906.
Jacques Curie, born at Paris on the 29th of October 1856, published an elaborate memoir on the specific inductive capacities of crystalline bodies (Ann.

Curie obtained only a fraction of a gramme of the chloride and Giesel 2 to 3 gramme of the bromide from a ton of uranium residues.
Karl von Gebler, who, in an able and exhaustive but somewhat prejudiced work, Galileo Galilei and die romische Curie (Stuttgart, 1876), sought to impeach the authenticity of a document of prime importance in the trial of 1633.

Blondlot and P. Curie afterwards suggested that a single electrometer could be constructed with two pairs of quadrants and a duplicate needle on one stem, so as to make two readings simultaneously and produce a deflection proportional at once to the power being taken up in the inductive circuit.
This research opened a way of approach to the phenomena of radioactivity, and the history of the steps by' hich P. Curie and Madame Curie were finally led to the discovery of radium is one of the most fascinating chapters in the history of science.
We thus see that radium is continually losing matter and energy as electricity; it is also losing energy as heat, for, as was observed by Curie and Laborde, the temperature of a radium salt is always a degree or two above that of the atmosphere, and they estimated that a gramme of pure radium would emit about 100 gramme-calories per hour.
