the groups ; I found several striking examples in 

 looking through the Codex Anonymus of the 

 Vatican, in which we found Spaniards holding 

 the sword in the left hand. This singularity of

 was something mysterious in this extraordinary 

 arrangement, which Mr. Zoega attributes only 

 to mere caprice, or the negligence of the artist.

 two sorts of copper, of which one was hard or 

 cutting, and the other malleable ; the hard cop-

 instruments of agriculture ; the malleable copper 

 was employed for vases, caldrons, and other
