those found in tlie published volumes. The number of stations used in these years 

 was different in different years. Generally six or eight were available.

Mauritius: Meteorological Observations taken during a number of years, and 

 published annually as a Mauritius blue book. 



Bombay : Magnetic and Meteorological Observations at the Government Obser- 

 vatory, Bombay. Bombay, printed at the Government Central Pi-ess, 1895. 



Batavia: Observations made at the Royal Magnetical and Meteorological Obser- 

 vatory, Batavia, 1900. Here only one station is available and the deviations as will 

 be seen from the table are larger in the mean than in the case of any others that have 

 been included. They received therefore only the weight 1. 



Ceylon : Administrative Reports on Meteorology. No general title in detail. 

 These publications contain monthly and annual means of observations at a number 

 of stations on the island. The deviations used here and elsewhere are the means of 

 generally six or more stations in various parts of the island. 



Australia : The sources for these observations are the annual publications of the 

 Adelaide Observatory hy Sir Charles Todd. The means given are generally those at 

 five or six different stations. 



Madras: Results of the meteorological observations made at the Government Ob- 

 servatory at Madras, — 1861-1890. Madras, 1892. Also other volumes partly with- 

 out title and partly bearing a similar title. 



Manila: Census of the Philippine Islands, 1903, Bulletin 2. The Climate of 

 the Philippines by Rev. Jose Algue, Director of the Philippine Weather Bureau, 

 published by the Census Office, Washington, 1904. 



Apia : The Deutsche Uberseeische Meteorologische Beobachtungen contains meteoro- 

 logical observations at a number of coast and island stations ; but, for the most part, 

 the observations are not pursued continuously through a sufficient period to be well 

 adapted to the present work. The best station for our purpose proved to be Apia 

 where the record is nearly complete since 1890. The unpublished results up to 1904 

 were courteously communicated by the Director of the Deutsche Seewarte at Hamburg. 



In equability and uniformity of temperature this station not only leads every 

 other on the list but every region. If therefore internal consistency had been the sole 

 guide in assigning weights, it would be entitled to greater weight than any other two
