Abstract
DURING my voyage hither from London in the Maranoa, viâ the Canal, and calling at Malta, Aden, and Colombo, I was surprised at the low values for ozone as registered by Moffat's tests, which I pinned to the “uprights” in Stevenson's thermometer screen. I tried periods of exposure varying from half an hour to twenty-four hours, and the highest value noted was but 5.6 for eight hours (scale 0 to 10). The test papers, however, were always tinted, more or less, sometimes to 3.0 in half an hour, whereas tests exposed at the same time and examined when eight hours had elapsed, only gave 4.6. At Ben Nevis and Fort William, and in the moorlands of Staffordshire I have recorded far higher ozone values than at sea under the same force of wind and like periods of exposure. From my long experience of these tests I cannot consider them satisfactory; but in the absence of a more reliable method I would strongly suggest that they would give results more intercomparable if uniformly exposed for an agreed hourly period, especially at the various land stations.
