was considerably greater on January 13 and 22 and February 1 
than on other days in January. 
Turning now to an adjacent geographical region, namely New 
Zealand, which is some 1200 miles away, the results of 50 stations 
for the period 1900-52 are given in Figure 7. Again there are peaks 
in the rainfall which happen in each case to be one day later than 
those in New South Wales. 
Turning to the northern hemisphere, Figure 8 shows bulk rain- 
fall records, again for the month of January, for four widely 
separated regions in the northern hemisphere, namely Great 
Britain, The United States, Japan, and the Netherlands. These, 
too, show characteristics almost identical with those in the south- 
ern hemisphere. _ 
It appears therefore that there must be some worldwide influ- 
ence on rainfall which leads to more rain than usual occurring all 
over the world on particular calendar dates. 
If, in fact, these variations in rainfall are a worldwide phenom- 
enon, they cannot have their origin in moving weather systems as 
normally conceived of. They must be due to an effect which can 
act simultaneously over the whole globe, namely an extraterres- 
trial influence. In addition, it must be an influence which is tied 
to particular calendar dates. The only extraterrestrial phenomena 
known to the author which satisfy these requirements are meteor 
showers, the majority of which recur each year on the same dates. 
The meteor particles exist in vast elliptical orbits around the sun,
