deserves further study. This eastward movement:may constitute a 
clue that will afford still further justification of the views here 
outlined. It may involve also a serious modification of existing ideas 
in regard to the influence of the rotation of the earth upon the 
deflection of air currents, about which there are some questions as yet 
unanswered. The general drift of the evidence is as above stated. 
It is only since modern facilities have come into existence that the 
adequate study of this subject has become possible. The present pur- 
pose will have been accomplished if it shall have been shown that there 
is a possibility of explaining the variations in the distribution of atmos- 
pheric pressure, and in the behaviour of storms in different years, 
points with reference to which, as far as is known to the writer, no 
explanation has even been attempted heretofore, at least not in any 
systematic way. 
ADDENDUM: Immediately after sending the above abstract my attention was 
called to the following item in Nature for June 5th, which had just come to hand. It is 
a remarkable confirmation of the position taken in my argument : 
‘«Mr. S. H. C. Hutchinson, Meteorological Reporter for Western India, has written 
an excellent ‘ Brief Sketch of the Meteorology of the Bombay Presidency in 1888-89.’ 
The meteorology of the year was characterized, Mr. Hutchinson says, by strongly marked 
deviations from the weather conditions of an average year. Of these, the most noteworthy 
were, a general rise of abnormal barometric pressure for a considerable period, a general 
deficiency of rainfall in September, and the scanty rainfall throughout the year. Mr, 
Hutchinson points out that all these variations are of much practical importance, and, 
from a scientific point of view, of considerable interest, inasmuch as they confirm the laws 
or principles deducted from the meteorological data of many past years. These laws or 
principles are, that the rainfall is deficient when barometric pressure is above the 
normal height, and excessive when the barometric pressure is lower than usual ; 
that at or about the epochs of minimum solar spotted area, high abnormal barometric 
pressure movements make their appearance, and that at or about the epochs of maximum 
solar spotted area, abnormally low pressure movements take place in India and over 
greater part of the tropics ; that cyclones are formed in the trough of a relatively minimum 
barometric pressure ; and lastly, that the number of atmospheric disturbances (in India) is 
great at the epoch of minimum sunspots.” —Walure, Fune 5, 1890, page 134.
