 tember 7th, 191 o. All these curves have a striking resemblance to each 

 other in shape, and also to the corrected curves of June 25th, 1910 (see 

 Fig. 25), while the curves based upon the unaltered temperature-readings 

 of the Nansen-thermometer of June 25th, 1910, differ strikingly in their 

 shapes (see Figs. 7 and 8) from all other curves.
