CLIMATE. 



Number of Days on which Rain, Hail, or Snow, more or less, 

 fell at York, by Mr. Ford's observations. 



In this way of judging, the most rainy month appears to be 

 October, the least so February. 



The degree of moisture in the air, though easily measured by 

 the wet- bulb or dew-point hygrometer, and really of paramount 

 importance to health and scientific agriculture, has been much 

 neglected by meteorological observers in Yorkshire. My own 

 registers supply the following series of wet-bulb observations at 

 10 A.M. for each month of one year at York. 



The numbers in the third column are an approximate (not an 

 accurate) expression of the relative dryness of the months.
