NO. 4 TEMPERATURE VARIATIONS IN THE NORTH ATLANTIC 245 



sudden irregularities, so that the crossing of the curve of the widened 

 known and unknown spectroscopic lines of Lockyer occurred. Most 

 terrestrial and solar curves (see for example fig-. 91, curves M and 

 C, and curves of figs. 95 and 96) show also a well marked change 

 of character about this time.

JURE 91. Curves la and Ih: temperature in Bombay according to Arctowski. II: anomalies of 

 ir temperature difference between Colombo and Hyderabad. Ill : temperature anomalies for 

 /ia. IV : yearly mean of the temperature anomalies for Bombay. V : yearly mean the tem- 

 aire anomalies for Leh. VI: anomalies for air pressure differences between the Azores maxi- 



and the Icelandic minimum, VII : temperature anomalies for all Norway. VIII : anomalies of 

 ir pressure differences between 30° north 30° west and Sao Thiago. IX : anomalies of the sur- 

 temperatures at Liepe's stations VI (18° north 21° west). M: anomalies of the daily variation 



agnetic declination in Christiania, the successive twelve-month mean minus the successive 

 '-six month mean. Scale on the left. R, C: consecutive twelve-month mean of the daily num- 

 f prominences according to observations at Rome (R) and Catania (C). All curves except IV 

 V^ indicate consecutive twelve-month means. 



Curve V, figure 91, gives the temperature variations in the high 

 level station Leh in north India in the Himalayas. The reader will 

 see that the temperature variations of this station go very well
