The Meteorological form brought in p use at "^^ beginning 

 of 1876 differs in some respects from he fo^I^^r one^ It has 

 been adopted with the view of assimilating the Hobart Tmvn 

 records more closely with those of stations in ^f 0P«' ^^^J.f^^^^i 

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

 feorology Readings are added from the centigrade ther^ 

 mometer, that being the instrument generally used on the 

 contineut of Europe. , .-, i.„„ 



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 is registered from cui;rents at a 

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

 square foot. ^, ,.„ , 



The relative quantity cf rain that fell under the different 

 wmds is registered each morning at 7-30 a.m. ,^.. ,, 



The 35 years' standard tables are used for obtaining . the 

 difference from average.
