The above abstract is tal^en from a series of records which have extended over the 

 last 35 years without intermission. Results of these observations for 30 years, em- 

 bodying all the elements usually recorded hitherto, have been previously published 

 by the Koyal Society of Tasmania in three separate parts. It has now, however, been 

 determined to commence a new series of observations more in accordance with forms 

 which have recently been adopted for Meteorological purposes.
