Excerpt from Results of Meteorological Observations Made at the Radcliffe Observatory, Oxford, in the Five Years 1921-1925, Vol. 54<br><br>IN its main features this volume is arranged on the same lines as for merly. It is formed Of five annual parts, the first four of which were printed soon after the completion of the years to which they refer, and a limited number were distributed for the convenience Of meteorologists who might wish to make immediate use of the data contained in them.<br><br>Certain changes in the routine of Observation have been introduced during this quinquennial period, the most important of which are the redue tion of the number of eye-readings from three to one per diem, and the dismantling and return to the Meteorological Office of the photographic barog'raph and thermographs, which had been in continuous use here since 1881, when they were Obtained on loan from the Meteorological Committee. These two changes took effect from the beginning of the year 1925, and they were introduced because it was considered that the full system of observations, that had been made here for a number of years, had served their purpose in providing us with an accurate knowledge. Of the climate of Oxford, and that adequate record of the weather in the future could be Obtained from a simpler system of eye-observations and from recording instruments more economical in time and money, than are the photographic recorders. The tables containing the results for 1925 are therefore necessarily different in form from those of the other four years, and a separate explanation of the tables is given for this year.<br><br>About the Publisher<br><br>Forgotten Books publishes hundreds of thousands of rare and classic books.
