n return in 15 minutes and take another reading.This method is open to great objections : first it is quite easy to make a false reading,and secondly in open-air work the leaves are not steady enough to allow of onereading being accurate. The method I adopted was to charge the two instruments,then take a reading of the dissipation instrument, half a minute later a reading ofthe ionization instrument, then at the minute take another reading of the dissipationinstrument, at the next half minute a second reading of the ionization instrument,and so on for 5 minutes, when of course I had five readings on each instrument.Ten minutes later I started reading again, and at minute intervals read each of theinstruments five times, then from a table found the value corresponding to each ofthe readings, took the mean of the first five, then that of the second five, and usedthese means as single values separated by an interval of 15 minutes.
