An closing the working up of the meteorological observations made on 

 the Norwegian Polar Expedition 1893 to 1896, I wish to here record my thanks 

 to Professor Nansen for intrusting me with this work, and for his practical aid 

 in carrying it out; to Capt. Scott-Hansen for his valuable information con- 

 cerning the observations themselves; to Miss Louise Mohn, who made the 

 main part of the computations ; to Mr. A. Graarud, first meteorologist in the 

 Norwegian Meteorological Institute, who made the harmonic-analysis calcula- 

 tions; and to Miss J. Muir, who has revised my English manuscript. The 

 proofs have been read by Miss Mohn, Mr. Graarud and Miss Muir.
