Magnetic re-action of Platina, 
In a piece of Russian Platina, the size ofawallnut, Gobel detected the two 
magnetic poles. Its magnetism was so powerful that a middle sized needle 
was attracted by it, and a magnetic needle was, at a certain distance, sfet in by 
it. Many similar pieces of Platina, from the size of a hazel nut to thaVof a 
hen’s egg, in the collection of the Imperial Mining Academy of St. Peters- 
burgh, exhibit similar properties.
