NOTES AND QUERIES.

If we now search out what are the chemical elements of the four systems 

 of metalliferous veins of Freiberg, we have the table following. In it the 

 elements are nearly arranged according to their frequency. Those which are 

 found at the head of the list are the most abundant, but there is some uncer- 

 tainty in the classification of those which are in. the middle. Although Oxy- 

 gen, Hydrogen, and Carbon play an important part, they are placed at the end, 

 as not being characteristic.
