MISCELIvANEOUS TABLKS. lix 



is not an exact multiple of the divisor, the nearest even multiple as given in 

 the table must be used. 



For example, 23979 -^ 28 = 856 ; the 8 is in the 9th column above 239 

 and the 56 is under 68, the nearest figure to 79 in the right-hand part of 



the table. 



The last column, which is separated from the rest of the table by a 

 triple line, is to be used when the quotient exceeds three figures, or 999. 



The bold-face figures in this column give the thousands and tens of 

 thousands figures of the quotient, and the plain figures are the multiples 

 thereof by the divisor. To use the column, find in it the number which, 

 with three ciphers added, comes nearest to (but is less than) the dividend ; 

 the heavy-face figures beneath it will be the first figures of the quotient. 

 Subtract this multiple number from the given dividend, and with the 

 remainder enter the main body of the table to obtain the last three figures 

 of the quotient as already described. 



For example : Divide 833885 by 28. The nearest figure to 833000 in the 

 last column is 812000 and the quotient 29000. 833885 — 812000 -= 21885. 

 Under 218 we have 7, and under 96, the nearest figure to 85 on the right, 

 we find 82. 833885^28 = 29782.

TABLE 100. 

 Table 100. List of meteorological stations. 



This list of meteorological stations has been compiled for this volume 

 from data furnished by the United States Weather Bureau. 



A geographical arrangement has been adopted as being most ser\dceable 

 for the purposes for which the table will most generally be used. 



In making the selection of stations from the vast number available, the 

 object has been to choose such of the higher order stations as will fairly 

 represent the varied climatic conditions of each country. With few excep- 

 tions, the stations are active ; in all cases there are published observations, 

 which may generally be found in the monthly and annual reports of the 

 national meteorological services of the countries in which the stations are 

 situated, or by which they are politically controlled. 



So far as known, the list contains all first order stations, i. e., those at 

 which the principal meteorological elements are either recorded continuously 

 and automatically, or are observed at hourly or bi-hourly intervals ; such 

 stations are designated by an asterisk (*). 



The names of the stations have been given in the native orthography, 

 which is in all cases the form adopted by the national meteorological service 



in its official publications.
