Look at what I found on the Online Galleries website!
The silvered and engraved register plates are flanked by two brass capped tapered columns.
These register plates indicate by the hinged brass pointer, the local barometric pressure and are calibrated for both winter reading from Hard Frost to Much Snow, on the right side and the rest of the year to the left, measured from very dry to stormy.
The stem was a front panel with moulded edge overlaid with the paper Royal Society thermometer scale. The central thermometer is filled with coloured alcohol. The left hand scale reads from Extreme Hot to Extreme Cold and the right hand side is calibrated 0-95.
This paper scale is bordered by wheatear design so typical on engraved dials and instruments of this period.
