trical observations. ‘The maximum pressure was 80°584 
inches in July, and the minimum 29° inches in September, 
giving a barometrical range upon the year of 1°584 inches. 
The highest monthly mean was 29°878 inches in July, and 
the lowest 29'575 in March ; the difference being ‘303 inches. 
The mean pressure of the year was 29°748. The maximum 
temperature occurred in January, when the thermometer stood 
at 105°; and the minimum in June, when it fell to 29°°4, 
giving a range in the course of the year of 75°°6. The highest 
mean temperature for any month was 59°°7 in January ; the 
lowest mean 48°°5 for July; the difference between them 
being 16°°2. The mean temperature for the whole year was 
51°, that for 1848 being 52°°3, and for 1847, 53°°2. 
The quantity of rain which fell monthly during 1849 is 
next given, as denoted by the Self-registering Rain-gauge at 
the Observatory ; the total being 33°51 inches for the year,— 
a larger fall than has been ever yet previously known, and, as 
Capt. Kay remarks, “ entirely contradicting the assumption, 
which the observations of previous years had warranted, of the 
alternation of wet and dry seasons.” The wettest months 
were May, July, and November ; the quantities in each being 
4-53, 5°99, and 8°94 inches respectively. 
Table 81 is an abstract of Meteorological observations 
registered at Launceston during 1849. The maximum pres- 
sure in the course of the year was in July 30°628 inches; 
the minimum in April 29°158, giving a barometrical range 
of 1°475 inches. The mean pressure for the year, deduced 
from these extremes, will be found to be 29°8905. ‘The 
maximum temperature occurred in February, when the ther- 
mometer stood at 85°; and the minimum in June, when it 
fell to 20°°5, giving a range in the course of the year of 64°°5. 
The mean temperature for the whole year, deduced from 
this monthly series of thermometrical observations, will be
