546 KANSAS CITY REVIEW OF SCIENCE. 
barges—by the transmission of electricity along an ordinary wire, generated by a 
machine one-third of a mile distant from the implement. Science can determine 
the quality of steam necessary to produce an electric current of a certain inten- 
sity, to yield a certain quantity of light; to determine the volume of a cable 
necessary to transmit instantly to the other side of the world a fixed number of 
words, and even when a break occurs in a cable, the point of interruption can 
be calculated to within a few yards. All this energy, all this power, is clearly a 
form of force. 
No precise ideas exist respecting ozone, it is only of late that the attempt 
has been made to distinguish it from oxygen; the truth is, the physical properties. 
of ozone are, up to the present, hardly known and cannot be distinguished from: 
those of oxygen. Messrs. Hautefeuille and Chapus have just prepared by low 
temperature and strong pressure, a mixture very rich in ozone, and peculiarly 
characterised by a blue or azure color. The same gentlemen are at present. 
occupied examining the vole of that coloring gas in the atmosphere and its influ- 
ence in diverse radiations. 
There is nothing positively known by Science respecting the cause of whoop- 
ing-cough, its evolutions, or its remedy. Doctors at best can only prescribe 
palliatives. It is an affection grave, entailing a mortality of five to ten per cent. 
It was generally considered that the inhalation of the vapors in the atmosphere: 
around gas works was an infallible remedy, but M. Roger has gone into the 
matter with the gas companies, who conclude, the children who do not return 
have been cured. The inhalation neither lessens the period of evolution of the 
disease, nor amends its nervous, febrile stages. 
PROCEEDINGS OF SOCIEiiEsS: 
FINAL PAPERS READ AT THE NATIONAL ACADEMY OF SCIENCE 
MEETING. 
The fall meeting of the National Academy of Sciences closed with five of the 
most brilliant papers on the list, and the Academy was declared adjourned by 
Prof. Marsh without a farewell address or other literary entertainment. Includ- 
ing the biographical notes by Prof. Cope, the Canids and Mimoravids of the 
Miocene formation of the West, and the memorandum of Prof. James Hall on 
the Relation of the Oneonta and Montrose sandstones to the sandstones of the 
Catskill Mountains, some twenty-seven papers have been read, many of them of 
permanent value, and some of them (such as Prof. Langley on the thermal bal- 
ance, and that of Prof. Wolcott Gibbs on the application of electrolysis to the 
quantitative determination of metals in (solutions) constituting landmarks of prog—
