| S/W 43875 C4C26.11.26. Hs.{Lord Ernest Hives - Chair} from C. WATER BOILING INDICATOR. Hs{Lord Ernest Hives - Chair}/Rn{Mr Robinson}1/LG20.11.26. We have examined the model of the proposed lamp. We suggest that the glass should be bigger - about the size of the rim of the sample, and of course it must be plain glass of a deep red. We also suggest it should match one of the other instruments - say the thermometer frame. We presume there will be no projecting bezel. Is the part which costs 25/- ? If so, it appears to be extremely expensive. C. | ||
