Mean annual rainfall for different countries of the globe. 
My sixteenth paper of “Contributions to Meteorology ” con- 
tained a table showing the annual rain-fall for 713 stations from 
various parts of the globe, and also a chart showing the lines 
of equal rain-fali as well as I could determine them from the 
observations then collected. I however distinctly stated that for 
Certain portions of the globe, and especially for the southern 
hemisphere, the observations were too few to enable us to 
draw the lines of equal rain-fall with confidence; and I re- 
quested that if any person should discover serious defects in 
my chart, he would communicate to me the observations which 
Indicate these defects. In response to this request I have 
received communications from numerous sources, of which the 
following are the most important: The Meteorological Service 
of the Dominion of Canada; the Meteorological Institute of 
Norway; the United States Signal Service; Dr. Alexander 
Woeikoff of St. Petersburgh ; Dr. A. von Danckelman of Leip- 
aig; Dr. Benjamin A. Gould of Cordoba; Professor Orville 
Dewey of Rio de Janeiro; Dr. Mauricio F. Draenert of Bahia: 
and Henry B. Joiner of S. Paulo, Brazil. I have also received 
the published observations of rain-fall from a large number of | a
