 The greatest heat in shade reached 7] -5^ in 1852, 



and only 52-9" in 1855, giving a range of 18-6'' in greatest 

 heat for March during the past eighteen years. 



The greatest cold was as low as 13" in 1845 

 (descending 1° below zero on the grass), and never 

 below 31-0'" in 1842, giving a range of 18-0° for March 

 during the past eighteen years. The coldest years 

 were 1845, 1850, 1852, 1853, and 1858; and the warmest, 

 1842, 1846, 1848, and 1851. 



Only 0-3 inch of rain fell in March, 1850, and as 

 much as 3-9 inches in 1848, giving arange of 30 inches, 

 or above 3J inches for March during the past seven- 

 teen years. In eight years the fall did not exceed an 

 inch, and in four years it was two inches and upwards. 

 The mean fall of rain for March is r4 inches. 



March is a changeable month, the range of tem- 

 perature being under 30° in 1842, 1846, and 1851, and 

 being 53" in 1858, and 53'6° in 1852. It is subject to 

 gales of wind. E. J. Lowe.
