. ANALYSES OF STONE METEORITES — FARRINGTON. 213 
Combining this sum with that previously obtained from 125 analyses 
of stone meteorites, stone meteorites being here regarded as all those 
which have an appreciable quantity of silicates, the sum total gives 
according to Clarke’s method* the average composition of meteorites 
as a whole. The method is, of course, empirical, but seems to be the 
only one available in our present state of knowledge. This sum is the 

following:

The present writer has previously suggested,f that the average 
composition of meteorites may represent the composition of the earth 
as a whole. If so the proportions of the elements in the earth as 
a whole would be as follows: 
PROPORTION OF ELEMENTS IN THE EARTH AS A WHOLE 
AS DEDUCED FROM METEORITES
