If. in accordance with the suggestion of Baron Nordenskjold,^ the 

 quantities of oxygen are neglected, it is found that the proportion 

 between the elements in this, and the Orvinio stone (August 31st, 

 1872), and in the meteorite of Tajima, Japan (February 18th, 1880), 

 are practically identical, thus establishing the interesting fact that 

 meteorites which fell in Japan one hundred and fifty years ago have 

 the same composition as some of those which have fallen recently, 

 both in Japan and on the other side of the globe.
