IN Meteorology, and especially as regards rainfall, continuity and uniformity of procedure are of paramount importance. It is, there fore, satisfactory to consider that this is the thirty-ninth consecutive Annual Report, and that though the volumes have grown enormously in dimensions, and additional details have been given, the general arrangement has been identical throughout. With a staff of observers numbering between 3,000 and 4,000, deaths and removals are inevitable; but we think that it is becoming exceedingly common for the observations commenced by one genera tion to be continued by the second; and in one case the record has been kept up by the same family, in the same spot, for four genera tions, without the loss of the observation for a single day. Such records for 30 or 40 consecutive years, are very important, and are becoming somewhat numerous. The British Rainfall volumes have gained their position by hard work, and by scrupulous attention to accuracy ; we have done all in our power to enable this volume to maintain the reputation of the series in that respect, and we trust that the details of the Angerton storm, and other notes as to Droughts, Whirlwinds, &c., scattered through the volume, will be of general interest. G. J. SYMONS. H. SOWERBY WALLIS. 62, CAMDEN SQUARE, LONDON, N.W. July J4th, 1899. REPORT. Cheeking ; a simple word, but expressive of one of the most arduous and wearisome portions of rainfall work. The checking of the returns utilized in this volume has taken quite ten months, i.e., three persons on an average 90 working days each. Probably many of our readers believe that our work consists chiefly in issuing blank forms, in receiving them filled up, and then in arranging the data contained in them, and sending the MS. to the printer. If it were so, our labour would be greatly reduced, but these volumes would lose their reputation, we should either have to print pages of errata, or do as many others do, print none at all, a complacent process perhaps, but certainly one that we shall never adopt. Nevertheless at times we cannot help wondering where the limit as to checking should be fixed. When British Rainfall was started, we verified the arithmetic of every return sent to us, that we have always done, and shall always do. We also adopted various plans for the detection of mistakes, which also we consider indispensable. At that time, with the exception of Mr. Glaisher's reports, and of those of the Registrar General for Scotland, scarcely any monthly or annual rainfall tables were printed, and therefore it was easy to compare all published tables with our own, and to hunt down discrepancies. This is far from the case in 1899. Some of the returns sent to us are published also in two, three, four, and even five different places, so that there are, perhaps (reckoning duplicates, triplicates, &c.), upwards of 1000 returns published in newspapers, pamphlets, and reports. Every one of these which we can obtain, is compared with the returns sent to us, and every discrepancy involves a letter to the observer asking for an explanation, and for a statement which is correct. Though nineteen times out of twenty, when there is a difference, it is the local publication which is wrong, yet sometimes it turns out that the observer has sent us a wrong figure, which no other process would have enabled us to detect. Aiming as we do at the greatest accuracy reasonably attainable, we suppose that all this checking must go on; but we wish that every one shared our desire for accuracy, and would 9 take equal care to secure it; we should then have some hundreds fewer letters to write. How many persons have adopted the rule which exists here, and which we have mentioned in these pages NEVER COPY A TOTAL ? " Oh ! " says the lazy man, " but it is such a bother to add it up again." Yes, my friend, but you forget that it would prove two things (1) that all the entries were correctly copied, and (2) that the addition was probably correct, and you forget also that if you have made a mistake, you will not only give others trouble, but will yourself be asked to examine it later on, so that you will really have more bother than if you had been careful at first. It is almost incredible how indifferent some few persons are. An observer had taken the rain each morning throughout the year, and sent a copy to us. In two of the months there was an error, either in one of the entries or in the addition. We sent the return back for examination. The observer tore up the record, and said that " he had not time to see what was wrong! " Persons of that tempera ment would be quite happy if they saw their names
