This month was wet, and also cold for the period of the 

 season. The mean temperature advanced only a fraction of a 

 degree from that of the preceding month ; the nights were, on 

 the whole, colder, and of these, the coldest was as late in the 

 month as the 29th, the thermometer being then at 27^°, Fahr. 

 and the radiator at nearly 1 5 0 , Fahr. Fruit trees, such as Pears, 

 Plums and Cherries, were only in blossom at the time, being a 

 fortnight later than usual. Many of the finest blossoms were 

 in consequence destroyed. 



On the 27th the clouds exhibited huge masses of strange ap- 

 pearance in regard to their form and colour, some being remar- 

 kably dark, and others like snow.
