October 14th, 1899 letter from Nikola Tesla to George Scherff #3

Colorado Springs, Oct. 14, 1899

Dear Mr. Scherff,

Please forward some writings of Prof. Dewar dealing with resistance of metals at low temperatures. You will find them somewhere as I have read them and put them away. He always sends me his papers. I want to look up something.

Sincerely,
N. Tesla
