 the gage at the railway station.

Precipitation. 



The differences observed in the rainfall totals from previously 

 published data, 1924- 1927, are due to the circumstance that 

 in the "Anales " the published data refer to the returns at 

 the railway station, while the values given here are from 

 the Meteorological Station, Chacras al Oeste. This is not 

 the station whose returns appear in "Anales," volume 18, 

 part 2, but are from the record of the late Dr. Lillo, who 

 observed from January 1884 to September 1930. The last 

 three months are from the Central Argentine Railway 

 Station.
