The percentages are given to the nearest whole number. 

 It may be gathered from Tables I., II., and III. that there 

 is a connection between perigee and volcanic and seismic 

 disturbances, 58°/> of the earthquakes (more than half) and 

 30*5f° (nearly one-third) of the eruptions falling at or within 

 a three days period from perigee. Between apogee and 

 seismic frequency there is no relation. Very little influence 

 can be ascribed to lunar phases, and the same might be 

 said of " Crossing the Equator." A very good verification 

 of these contentions is that no disturbances were felt 

 between March 20th -24th, 1903, the equinox itself, but at 

 the previous and following perigee, of March 10th and 

 April 5th both eruptions and earthquakes were recorded. 

 New moon and full moon were likewise beyond the three 

 days' limit. In September 1903, however, perigee, new 

 moon, and moon crossing the equator, all happened to occur 

 close together and at the time of the equinox. At the same
