It may be remarked with reference to the first table, that 

 the number of magnetic disturbances recorded of a nature 

 generally accompanying auroras, is greater than that of 

 observed auroral phenomena ; it is very probable, however, 

 that on many of these occasions auroras occurred, but by 

 reason of cloud, haze, or moonlight were not observed here. 

 During 1869 and early part of 1870, the Zodiacal light was 

 very frequently seen, and sometimes of considerable bright- 

 ness. Since the great auroral period has set in (April 5), 

 it has onh^ been observed faintly on one or two occasions. 



The mean temperature, humidit}^, and rainfall, for each 

 month of this auroral period, as compared with the means 

 of the same months for the last twelve years, is as follows :
