The Jleteorological fcrm brought into use at the begmmng 

 of \m differs in some respects from the former one. it has i 

 been aclopte-l with the view of assimilating the Hobart iowu ; 

 records more closely with those of stations in Europe, America 

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

 Meteorology. Readin£?s are added from the centigrade ther- 

 mometer, that being the instrument generally used on the 

 contineut of Europe. , ^, , 



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

 daily registers,, not from the maximum and minimum. 



The direction of the wind f registered from cun^ents at a 

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

 square foot. 



The relative quantity of rain tliat fell under the different 

 winds is registered ea'-^ «.orning at 7-30 a.m. 



The 35 years' standard tables are used for obtaining the 

 difference from average.
