The Meteorological form brought into use at the beginning 

 of 1876 differs in some respects from the former one. It has 

 been adopted with the view of assimilating the Hobart Town 

 records more closely -vvith those of stations in Europe, America, 

 etc., in order to co-operate in a system of International 

 Meteorology. Readings are added from the centigrade ther- 

 mometer, that being the instrument generally used on the 

 contment of Europe. 



The mean is in all cases taken from the sums of the two 



i7 "^^f^sters, not from the maximum and minimum. 



The direction of the wind is registered from currents at a 

 height of 92 feet above sea level, and its force in lbs. per 

 Square foot. 



The relative quantity of rain that fell under the different 

 wina? 13 registered each morning at 7-30 a.m, 



The 35 years' standard tables are used for obtaining the 

 difference from average.
