"We bave just given tbe reason why ibe brown-yellow was assigned to 

 tbc palaiolitbic age. As regards tbe metals we bave connected tbem as

 tbe principal element of wbicb is red coi)i)er. Tbe blue is relegated to 

 tbe iron, wbicb fieqnently reflects tbat color. Tbese tints are so natural 

 tbat tbey were always employed by tbe Egyptians many centuries ago.

 and taking into account tbe discussion of tbe commission appointed by 

 tbe International Congress at iStockbolm, as well as tbe learned commu-

 ologists wbo are occupied witb prebistoric studies, tbis collective work, 

 wbicb is sufficiently simple, distinct, and precise for all tbeir needs.
