New invention for separating gold...

Item # 678932

March 15, 1856

SCIENTIFIC AMERICAN, New York, March 15, 1856  The front page features a nice print of a: "Machine For Washing & Separating Gold" with a related article headed: "Addison's Improved Gold Separator". Perhaps not surprising that just a few years after the California gold rush that relating inventions would come to fruition.
The balance of the issue is filled with various scientific inventions & improvements of the day.
Sixteen pages, good condition.
