METEOROLOGICAL RESULTS OF LAST CRUISE OF CARNEGIE 
corrections to the recorded air temperatures based on 
such observations could be made. The Hartmann and 
Braun traces, therefore, could not be used for obtaining 
continuous records of lapse rates. 
Evaluation of Thermograms 
The corrections to the Negretti-Zambra and the 
Hartmann and Braun thermographs were found by means and applied tothe reading of the thermographat that hour.

of the noon readings of the Assmann psychrometer. As 
soon as the air temperatures were obtained with the 
Assmann instrument, the pens were removed from the 
traces on the thermograms, and these readings entered 
directly on the sheet. The final corrections were used 
for constructing a curve which was entered directly on 
the thermogram, showing the correction as a function of 
time. From this curve the correction at any hour was read
