I found 0°01 inch or more of rainfall in my guage on 190 days during 1874. 
I say rainfall, but in many cases there was no rain, properly speaking, the deposit 
being caused by condensation of fog or dew. Snow is simply frozen rain, but I 
allude to fog and dew in order to show the necessity of examining the bottle of the 
rain-guage every morning without fail, even in the dryest weather. A deposit of 
0°01 inch from dew will be frequently found when least suspected, and this should 
be always recorded. In fact, unless observers examine their guages every day, 
they should not make a return of wet and dry days (so called), because their 
figures will in the end lead to wrong conclusions. 
The following figures will enable the reader to compare the rainfall of the 
past year with the dryest year and the wettest year since rainfall observations 
were commenced in this county :—
