8$ ArdowsM— /'/, ionia/i Cycle of Climatic Fluctuations. 



For the same years 1909-1913 I have prepared more 

 than 150 curves of overlapping temperature means of stations 

 from all parts of the world. This amount of already computed 

 data is very respectable, hut of course I am anxious to obtain 

 more data, and I do not think that the difficulties one encoun- 

 ters in collecting the results of meteorological observations 

 made in some countries or the shocking mistakes that may be 

 found in the tabulations of official publications of some other 

 countries, will prevent me from trying to make my research as 

 thorough as possible. 



If my reasoning is correct, it follows that at the time of the 

 occurrence of the horme-pleionian maximum of 1911:6, or 

 shortly afterwards, we should observe thermo-pleionian crests 

 on the curves of overlapping means of the observed tempera 1 - 

 tures. Or, since it has been found that in no case studied so 

 far, temperature was above the average all over the world, that, 

 on the contrary, anti-pleions always compensate the pleions, 

 more or less, it will be necessary to find at least a predominance 

 of thermo-pleions synchronal with the solar maximum. 



And so it seems to be. 



Of the records studied so far I may say that an abnormal 

 increase of temperature during the latter part of 1911 and 1912 

 is a striking feature of the curves of meteorological stations in 

 Alaska, British Columbia, Vancouver Isl., Oregon, and, to a 

 certain extent, California, then of Mexico, Panama, the West 

 Indies and Bahamas, British and French Guiana, Matto Grosso, 

 Parana, Peru, — the Faroe Isls., Holland, Northern Germany, 

 Switzerland, Italy, Gibraltar, — Algeria, Morocco, the Canary 

 Isls., the Sahara, Egypt, Senegambia, the French Congo, the 

 Transvaal, — Aden, Quetta, India, Ceylon, Mauritius and Sey- 

 chelles Isls., the Strait Settlements, Cochinchina, China, Japan, 

 Eastern Siberia, — Australia, and the Touamotou Isl. in the 

 Pacific. 



The records of a certain number of stations show a retarded 

 pleionian effect. I will cite those of Greenland, Iceland, Caro- 

 lina, Florida, Cuba, — the Caucasus and Russia, — Southern 

 Nigeria, Togo, German South Africa, Madagascar, — Palestine, 

 Mesopotamia, some stations of India, Christmas Isl., the 

 Philippines, and New Caledonia. Even in the Antarctic 

 regions the records of Cape Evans station, under 77° 38' S. lat., 

 show that during the months of May to September, or during 

 the South polar winter, the mean temperature in 1912 was 

 10° F. higher than in 1911. 



In striking contrast with these results most stations of the 

 United States, as well as Wellington and Auckland in New 

 Zealand, and some stations in Russia, show a well pronounced 

 depression of temperature corresponding in time with the
