By Wiuu1am J. S. Locxysr, .A., Ph.D., ERAS. 
The first portion of this paper dealt with the short-period barometric see-saw 
which has been found by the author and Sir Norman Lockyer to exist between 
two antipodal regions on the earth’s surface. This investigation, which has been 
published by the Royal Society,' has already been referred to in detail. 
- essence of the second portion may be briefly summarised in the following 
words :— 
_ The variation of the barometric pressure over India from year to year is the 
inverse of that over Cordoba, in South America—that is, when the pressure over
