The Meteorological form brought into use at the beginning 

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

 been Hilopted with the view of assimilating the Hobart Town 

 records more closely with 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 

 coutineut cf Europe. 



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

 '^uy repisteri, not from the maximum and minimum. 



The ditiotion of the wind is registered from currents at a 

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

 s^inare foot. 



.The relative quantity cf rain that fell under the different 

 Winds is registered each n.crning at 7-30 a.m. 



Ihe 35 years' standard tables are used for obtaining the 

 <utference from average.
