The readings on the micrometer head are now reduced to a 
standard position of the level and the temperature readings are 
corrected. This gives the following.

Nothing new was in the method used for the determination of resistance. 
It is hence only necessary to give the final results, as the means of 
the various measurements reduced to the same time. 
To calculate the temperature we have used the following preliminary 
formula, obtained in the measurements described in Comm. N°. 77
