For several years I have been engaged on the spectrum analysis of Meteorites. Many meteoric specimens have come into my possession—through the kindness of friends— especially am I indebted to the Trustees of the Natural History Museum and to Dr. Prior, who presented me with specimens of such of the meteorites of which the quantity in their possession would not be appreciably diminished by the loss of the two or three grms. required for my experiments. The Research is divided naturally into the examination of meteoric stones and meteoric irons. I propose at present to deal with meteoric stones or aerolites. These wonders of the sky consist generally of one or more silicates (mainly olivine and bronzite), interspersed with particles of nickeliferous iron, troilite, &c. Recent developments have led to many original devices and modification of details in the working spectrograph, thus furnishing information which may be of interest to those engaged on this branch of spectroscopic analysis.
