METEOROLOGY FOR JULY, 1877. 

 Private Observatory, Hobart Town". 



Latitude 42° 52' 13" S. ; Longitude 9h. 49m. 29.2s. E. 

 (Registered for the Royal Society of Tasmania.) 



The Meteorological form brought into use at the beginning 

 of li>76 differs in some respects from the former one. It has 

 been adopted with the view of assimilatiug the Hobart Town 

 record.s more closely with those of stations in Europe, America, 

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

 Meteorology. Readings are added from the centigrade ther- 

 mometer, that being the instrument generally used on the 

 continent of lilurope. 



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 currents at a 

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

 square foot. 



Tlie 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 

 difference from average.

 were not registered, consequently the above means are from 

 27 days only. As it is in the same valley the removal is not 

 expected to influence the results iu any material degree.
