to these observations from April 1933 to September 1934 to 

 reduce to the height of 25 m. Height of station from March 

 17, 1938, to date, 25.22 m. 



CATAMARCA 



Pressure. 



Height, 511 m. to March 31, 1929; 528 m. from April i, 1929, 

 to October 24, 1935; 516.77 m. from October 25, 1935, to 

 date. A correction of +1.5 mm. was added to the observed 

 pressures from January 1931 to October 1935, and +0.4 

 from November 1935 to December 1940 to reduce the ob- 

 served monthly mean pressures to the old height of 510 m. 

 given in Smithsonian Misc. Coll., vols. 79 and 90. 



CORDOBA 



Pressure. 



The latest determination of the height of the barometer at Cordoba 

 is 425.1 m. The barometer has remained in the same place 

 since the beginning of observations, and previously pub- 

 lished heights should be 425.1 m. instead of those given. 



GOYA 



Pressure. 



Height, 36.95 m. from June 13, 1930, to September 4, 1931 ; 

 36.40 m. from September 5, 1931, to October 25, 1935; 

 37.16 m. from October 26, 1935, to date. 

 Editor's Note. 



A change in the height of the barometer to 37 m. is recorded 

 about January 1928, but such a change is not reflected in 

 the monthly means of pressure. 



HARDING GREEN (BAHIA BLANCA) (PUERTO BELGRANO) 



Pressure. 



Observations of pressure taken at Bahia Blanca January 1931 to 

 December 1931, Lat. 38° 43' S., Long. 62° 16' W., Hb = 29 m. 

 The station at Puerto Belgrano, Lat. 38° 55' S., Long. 

 62° 4' W., Hb=io.5 m., was then substituted for Bahia 

 Blanca for the years 1932- 1936. After rather a long break 

 the station was moved to Harding Green, Lat. 38° 43' S., 

 Long. 62° 9' W., height above sea level, 73.77 m. September 

 1940, the station was moved to the aerodrome located in the
