DENSITY AND TEMPERATURE COASTAL WATERS 143 



SESSIONAL PAPER No. 38a 



The tein,perature readings were made, in the first and part of the sixth set, 

 with a Negretti and Zambra deep-sea thermometer, standardized against the other 

 thermometers used, and in the remaining series, with a Richter deep-sea ther- 

 mometer, standardized at the Physikalische Technische Eeichanstalt, Charlottenburg. 

 The samples of water were obtained in a Pettersen-Nansen deep-sea water bottle. 

 As the density readings were taken at room temperature, the correction, for 15° 

 C. has been applied in each case. 



Some curves to illustrate are shown in fig. 2.
