Extract

In the Rose-Tschermak-Brezina classification of meteorites the intermediate class of stony-irons, in which iron and stony matter occur in approximately equal amounts and to which Maskelyne gave the name siderolites, is divided into (1) siderolites proper, including the groups of the pallasites and the siderophyres, and (2) lithosiderites, comprising the groups of tile mesosiderites, glahamites, and ]odranites. Mesosiderites are defined as consisting of iron and crystalline olivine and bronzite, and grahamites of the same constituents with the addition of plagioclasefelspar.

page 158 note 4 In the calculation of the bulk-analysis, analysis (1) of the attracted, with the loss evenly distributed over the constituents, was used.
