The observations of the temperature of the "surface" are not very trust- 

 worthy. They may give the temperature of the snow, in which the thermo-

 towards the sky (or sun). 



From the middle of April, 1894, to the end of June of the same year, 

 the ice-temperatures were observed at 8 a. m. and at 8 p. m. The mean is 

 taken in the tables. Subsequently generally at 8 a. m. The following Tables 

 give the observed temperatures, corrected for the errors of the thermometers.
