MR ROBERT COCKBURN MOBSMAN ON 



(the black auchty-twa), with forty-seven entries, closely followed by 1838 with forty-six 

 days, and 1814 with forty-five days. On the other hand, snow fell on only three days 

 in 1856, the number being below ten in eleven years. Grouping the results by winters, 

 a slightly different arrangement obtains, the snowiest being the winter of 1836-37 with 

 forty-nine days, while the winter of 1850-51 had but two snowfalls. With the exception 

 of a little sleet on September 23, 1893, no snow fell in the months of June, July, 

 August and September.

The snowiest month was thus March, 1812, with sixteen days on which snow 



fell. 



The earliest date of first snow was October 1 (see Table XXXIX.) in the year 



1817, and the latest January 31, in the winters of 1850-51 and 1857-58. The latest 



date of last snowfall was May 30, 1808, and the earliest January 17, 1853. The mean 



date of first snowfall is November 22, and the mean date of latest fall, April 10. 



Hail. 



Table XL. shows the number of times hail fell during the 127 years 1770-1896, 

 for each month and the year. The mean annual number of days with hail is ten, the 

 maximum being thirty-two days in 1824, and the minimum one day in 1848. The 

 greatest number of days in each month is shown in the following Table : —
