Remarks. 



January. — The wettest on record at this place. Those months 

 which approach the nearest to January 1851 in point of wetness 

 during the last nineteen years, are December 1833, January 1834, 

 and July 1846, in each of which the fall of rain slightly exceeded 

 9 inches. At Scathwaite in Borrowdale, the fall was 28*63 inches, 

 and on the " Stye'' it amounted to no less than 38-86 inches, by 

 far the greatest quantity ever measured in the same period in Great 

 Britain. 



The mean temperature is 4°-66 above the average of the preced- 

 ing eighteen years. 



February. — Wet till the 19th; fine and clear during the re- 

 mainder of the month. Mean temperature, 2 o, 09 above the average. 

 During January and February, the thermometer reached the freez- 

 ing point on two nights only. 



March. — Mild, with an unusual absence of easterly winds. 

 Temperature 1°*87 above the average. 



The temperature of the quarter ending March 31, is 2°-87 

 above the average. 



The deaths in the town and suburb of Preston Quarter, are 155, 

 beino- three above the calculated average of the preceding twelve 

 years, allowing for increase in population. 



April. — A very fine, but somewhat cold month. Sun shone out 

 more or less on 29 days. Mean temperature, 0°*57 below the 

 average.
