sion of the mercury column due to the higher temperature of the air in which the 

 reading was taken could be made. The Richter thermometer was reversed by the 

 same messenger which reversed the water bottle. The Negretti and Zambra ther- 

 mometer was used on a separate sounding line in a Maghnani case, which is reversed 

 by a propeller which turned only when the thermometer was being raised. 



The Richter thermometer had been tested by leaving it in the standard tem- 

 peratures for fifteen minutes. It was found that readings made after the thermometer 

 had remained four minutes at a given depth differed from those obtained after 

 fifteen miniites by less than one-tenth of a degree. It was also found that the cor- 

 rection for the expansion of the mercury column for the temperatures measured was 

 about twenty-five thousandths of a degree. In the work, the thermometer was left 

 at the required depth for four minutes and the correction neglected. Tests with the 

 -Negretti & Zambra thermometer showed it to reach the temperature of the surround- 

 ing water after three minutes. In the above observations it was left at the depth 

 recorded for three minutes. 



The densities were determined with the hydrometer at room temperature and 

 then corrected to read at 60° F. or 15-56° C. by Buchanan's^ diagram.
