 (Registered for the Eoyal Society of Tasmania.) 



The lletyorological form brought into use at the beginning i 

 of 1>7G differs in some respects from the former one. It has ! 

 been adopted uith the view of assimilating the Hobart Town j 

 records more closely with those of stations in Europe, America, | 

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

 Meteorology. Readings are added from tne centigrade ther- : 

 inometer, that being the instrument generally used on the 

 continent of Europe. 



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



i- ^^Si^ters, not from the maximum and minimum. 



The direction of the wind is registered from currents at a 

 Height of 1)2 feet above sea level, and its force in lbs. per 

 t'ljijire foot. 



The relative quantity of rain that fell under the different 

 winds is registered each morning at 7 -30 a.m. 



The 35 years' standard tables are used for obtaining the 

 rtiirerence from average.
