In some cases different analyses of the same meteorite require it 
to be placed in more than one group. Such cases indicate that further 
analyses are needed. In Busti for example there seems to be no way 
of determining whether Dancer’s or Maskelyne’s analysis is the more 
nearly correct and both must be used, but further analyses would 
probably furnish ground for eliminating one or the other. It is quite 
possible that a similar confusion would appear in terrestrial rocks if 
analyses of the same rock made at widely different times and by dif- 
ferent analysts were compared. While some such discrepancies occur, 
in most cases plural analyses agree in placing the meteorite in the same 
group. This is true for example, of Homestead, New Concord, Aussun, 
Hessle, and others. In such cases the plurality of analyses happily 
confirms the placing of the meteorite. An opportunity for comparison 
of the grouping of meteorites in the quantitative classification with 
that of Rose, Tschermak, and Brezina is afforded by the Brezina symbol 
of each meteorite given in the tables. Comparison shows that on the 
whole the important groups of the German classification remain intact 
in the quantitative classification. Thus the howardities, eukrites, and 
chladnites occupy on the whole similar and separate places in both 
classifications. Among the subgroups of the chondrites little similarity 
of grouping in the two classifications can be noted, though the gray 
chondrites and spherical chondrites are rather more numerous among 
the less siliceous groups of the quantitative classification. This would 
be expected since the color and structure of the meteorites of these 
groups indicate a larger proportion of olivine than in the white or inter- 
mediate chondrites. Such a scattering of these groups, however, on
