Who coined the term "relativistic mass"

I asked this question before and never got an answer. I'm hoping that new people are on here who might just know the answer to the question: Who coined the term "relativistic mass" and where, i.e. I need a reference so I can read the source of the terms original usage. Thanks in advance.

ps - I plead with the forum not to turn this into a debate about the concepts usage. Thanks.

http://en.wikipedia.org/wiki/Mass_in_special_relativity#Modern_relativistic_concepts" claims it was Richard C. Tolman:

The velocity dependent mass of Lorentz and Abraham were replaced by the concept of relativistic mass, an expression which was coined by Richard C. Tolman in 1912, who stated: “the expression m_0(1 - v^2/c^2)^{-1/2} is best suited for THE mass of a moving body.”[13]

Reference 13 is R. Tolman, Philosophical Magazine 23, 375 (1912).

Tolman never used the term "relativistic mass" in that paper. Its the term and not the quantity that I'm looking for. I read that paper and the term is not used in it. Thanks.
