All these stations, be it observed, are in Western Siberia or European 

 Kussia ; and it now becomes of interest to ascertain over -what area this 

 kind of oscillation obtains. To do this, I have tabulated the barometric 

 data for Tillis on the South-west, and Nertscliinsk and Pekin on the East. 

 No one of these stations exhibits characters resembling those of the stations 

 in Western Siberia ; and the curve of Pekin, which is fragmentary, seems 

 rather to exhibit the Indo-Malayan type of variation than that of the 

 Ural stations. Hence, it would seem there is a reciprocal oscillation of 

 atmospheric pressure between Western Siberia and the Indo-Malayan region
