the amplitude of the annual and other terms in the temperature curve at each 

 kilometre up to 15. The figures are based on some 400 ascents made from 10 stations, 

 chiefly on the Continent. 



Dr. ARTHUR WAGNEU has also given values based on 380 ascents between July, 

 1902, and June, 1907 (' Die Temperaturverhiiltnisse in der freien Atmosphare,' 

 III. Band, Heft 2/3, Leipzig, 1909), and in the ' Meteorologische Zeitschrift' for 

 January, 1911, the translation of a paper in Russian by M. M. RYKATCHEW, jun., 

 appears. In it the results of 143 ascents in Russia, mostly at Pawlowsk, are brought 

 together. 



The four values thus obtained are shown side by side in Table IV., and I do not 

 think that anyone can fail to notice the close agreement. With regard to the mean 

 annual temperatures, except at Pawlowsk, the values hardly differ by 1 C. at any

height, and the lower temperature at Pawlowsk is due to its higher latitude, and 

 this, in accordance with a general rule, is reversed above. 



The amplitude is least in England and greatest in Russia, but an exact comparison 

 cannot be made because in columns W. and R. half the range between the two 

 extreme months is given and not the amplitude of the curve. 



The phase angles are not available for columns W. and R., but it is obvious from
