Excerpt from Manual of Meteorology: Volume II Comparative Meteorology From the study of Meteorology in History as set out in the introductory volume of this Manual the conclusion was arrived at that the primary need of the science was a sufficient knowledge of the facts about the atmosphere in its length and breadth and thickness to furnish a satisfactory representation of the general circulation and its changes. The present volume is intended to provide the reader with the means of making himself acquainted with the nature and extent of the material which is available for satisfying that need. In the first place the normal general circulation and its seasonal changes are represented by maps, tables and diagrams, with references to the original sources for further details. Next the transitory changes are dealt with, first by considering the results of the purely arithmetical methods of chronology, periodicity and correlation, and secondly by the results of the graphic methods of the weather-map in combination with the autographic records of the meteorological observatory. Incidentally we should like to call attention to remarkable evidence of the effectiveness of the maps in the case of pressure, notwithstanding their small size. It will be found on p.213. The tables and diagrams which are added to supplement the information contained in the maps are only samples of many possible compilations. Their number and extent are necessarily limited by the considerations which control the size of the volume. In so far as those tables and diagrams are successful they will recall the suggestion of the preface to the first volume, of an encyclopaedia or dictionary which would embody information of that character for all parts of the world. If each year a part were brought up to date the whole would constitute a permanent work of reference to which a student could turn for information now accessible only to the few privileged persons who live within easy access of a meteorological library. The advantage of some provision of that kind will be apparent to the reader who notices the discontinuous and unceremonious introduction of certain information in the form of supplementary tables.
