NOTE ON STRZELECKI'S DETERMINATIONS OF 

 HEIGHTS IN TASMANIA. 



Messrs. Giblin, Piesse and Hutcliisou, in llieir paper on 

 the Heiglit of Beii Lomond (ante, pp. 5-14), refer, at p. 13,. 

 to Count Strzelecki's determinations of the heights of several 

 summits on Ben Lomond. 



Couut Strzelecki, in 1841, determined many heights in 

 Tasmania. These wer*^ published in the Tas7nama?t Journal, 

 i., 147-9, and afterwards in the work quoted on p. 13. These 

 heights, though determined with great care by the use of Gav 

 Lussac's syphon mountain barometers and WoUaston's boil- 

 ing point apparatus, difiPer considerably from the heights 

 found subsequently in the trigonometrical survey. 



The following note from these Papers and Proctedings f(»r 

 1849 (i., 168) is therefore of some interest: — 



13th June, 1849. "Sir William Denison stated that tli a 

 "instruments used by Count Slrzelecki, and since purchased 

 " by Government, have been found very faulty— a fact which 

 " may account for some obvious errors in tlie elevations re- 

 " corded by that gentleman."
