I wonder if anyone can help with this question, which has come up at work here. I'm sure it's something I used to know, but I cannot remember and I can't find anything on the web. It apparently used mercury (de rigour for all classic science apparatus of course).

There was a Bailey who worked on Induction Motors in the 1880s, Tesla refers to his designs in his patents.

This article describes a Bailey bottle and is used for the same thing:

I bet that's it orionjim ! This is about waste mercury in some old industrial premises stores. They quite probably used to do gas analyses, so this fits in very well.

Captain Swoop, I too searched through a lot of VICTOR Bailey material, and there is some electrical apparatus that looks to be commonly named after him. I couldn't find any real detail though.

I'm 99% sure though, it will be the CAMERON Bailey's apparatus, as the gas-sampling fits in with what they used to get up to on the premises.

Thanks everyone
