METEORIC STONE FROM SIMONDIUM.— At a meeting 

 ■of the Mineralogical Society, London, held on the 16th 

 November, Dr. G. T. Prior communicated some particulars re- 

 specting fragments of a meteoric stone which had been discovered 

 two years previously near Simondium Railway Station, on the 

 Paarl-French Hoek line, Cape Colony. The largest fragment 

 did not exceed one foot in diameter. Smaller pieces of the 

 meteorite had been presented to the British Museum. They 

 belong to the less common class of aerolites which show no chon- 

 dritic structure. The components of the stone were found to be 

 enstatite, olivine, and felspar, together with some troilite, mag- 

 netite, and nickel-iron, the last named of which had been assumed 

 to be native silver by the prospectors who discovered the meteorite. 



THE SUN'S MOTION RELATIVELY TO THE ETHER.— 



Dr. C. V. Burton recently discussed before the Phj'sical Society 

 the possibility of determining the motion of the Solar System., 

 relatively to the Ether, from observations of the eclipses of 

 Jupiter's satellites — a possibility which had been indicated by 

 ■Clerk- Maxwell more than thirty years ago. Assuming, for 

 convenience, that the sun is stationary, the motion of the ether, 

 relatively thereto, may be said to partake of the nature of 

 a wind. Under such circumstances, the light-waves, which 

 bring us tidings of a Jovian lunar eclipse, will, it is considered, 

 travel earthwards more rapidly when Jupiter's system is to wind- 

 ward of the earth than when it is to leeward. The residual dis- 

 crepancies between the observed and calculated times of the 

 eclipses would afford a means of measuring the velocity of this 

 ether " wind," that is, would, after proper allowance and correction 

 for systematic differences, gives values for the components of the 

 sun's velocity with respect to the ether. As material capable 

 of forming a basis of calculation attention is drawn to Prof. 

 Sampson's discussion of the Harvard photometric eclipse ob- 

 servations, including over 330 eclipses of Jupiter's satellite I.
