PROCEEDINGS OP THE CALIFORNIA 



Table 1. — Giving the number of shocks in each month of the year, for thirteen 



years. 



Table 2. — Number of shocks occurring between the dates of the equinoxes and 



solstices, for thirteen years. 



I regret that my records of the occurrence of earthquakes upon the east 

 coast of the United States is not more complete than it is, and also that it does 

 not extend through an equivalent period of time as our own, from 1850 to date ; 

 but I have no authentic records of their occurrence on the other side later than 

 1854 ; my business at that time, and the subsequent period that has elapsed, 

 bein<? such that I was not able to maintain their continuation. In order to 

 prove the statement made on a preceding page correct as to our relative im- 

 munity on this coast over equal extent of territory, I here subjoin the totals 

 on both coasts during that period of time. This statement will also include 

 those shocks which were matters of record belonging to the West India Islands, 

 and which properly belong to the eastern-coast series. 



The figures relating to this matter, stands thus : 



In California during 1850, five shocks ; 1851, six shocks ; 1852, two shocks ; 

 1853, thirteen shocks ; 1854, eleven shocks. Total, thirty-seven shocks.
