Heres something a little different.

Air and rain. The beginnings of a chemical climatology (1872)

What I found very interesting were the O2 readings taken when many of our favourite haunts were working in 1864.

There was a report with the title (similar to) "An investigation into the working conditions of British Mines" in 1864. The data is in an appendix (fat book) in the back of the Cornwall Studies Library. It's a fascinating read and I think the data is the same as that to which you refer.

I'm not sure what's up with their chemistry, but their number seem awfully high to me. I would state with virtual certainty that they are out by a degree.

As you say interesting stuff Chris!
You will have noted that there were no Smallcleugh readings.
By this time I guess only tributing was taking place in the flats and the rich find on Great Cross Vein had been extracted.

The work in the incline flats started just after this date.

I carried out readings on Scaleburn and the greater the distance you went in the less Oxygen was present. Which was one of the reasons we abandoned the dig.
However when the mines were working ventilation would be present down the many interconnecting sumps and rises many of which are now blocked

There are Smallcleugh readings hidden away at the bottom of page 29 (or 101 original numbering)

Its the Kinnaird Commission, full title: "Report of the Commissioners appointed to enquire into the condition of all mines in Great Britain to which the provision of the Act 23 & 24 Vict. Cap. 151 do not apply, with reference to the health and safety of persons employed in such mines with appendices" Royal Commission on Mines, London: HMSO, 1864. If I recall correctly, it comprises a summary report, a second volume setting out evidence and findings at length, and two large volumes of appendices that contain the verbatim evidence of witnesses interviewed in the main non-ferrous mining fields of the UK.

The title has the earliest occurrence of the phrase "health and safety" that I have encountered.

Found the Smalllcleugh references as you say hidden, but with no quoted values , just the temperature and the number of men working which is relatively high.
One interesting in feature is trying to figure out where some of the samples were taken.
Eg a large Cavity in Rampgill mine, was this in the boundary flats or where?
You could raise lots of other interesting examples. However, Chris you have raised lots of points for us all to mull over.

Good
