Re: [BKARTS] Faraday

Ammonia came to be added to illuminating gas to neutralize sulfur,
but the problem was not completely solved.

Some seventy years later the U.S. Bureau of Standards was to publish
methods for detecting acidic and alkaline gases.

Technologic Papers of the Bureau of Standards No. 20:
"Determination of sulfur in illuminating gas," by R.S. McBride &
E.R. Weaver.  1913.

And No. 34, in 1914:
"Determination of ammonia in illuminating gas," by J. D. Edwards.

But by this time electric lighting was in wide use in public buildings
in the U.S. and Europe, so curators, librarians, and building engineers
could focus their attention on cleaning the air inside buildings.
