 and part o/l827 a7id 1829 {Old Style). 



The barometer used in the preceding observations was 

 compared with that of M. Lulke. He found that the former 

 constantly indicated a height 0-32 inch less than the latter. 

 The barometer of M. Lutke having been compared with that 

 of the observatory of Copenhagen, its indications maybe re- 

 garded as exact. 



Adding 0"32 to the above mean, we find for the mean baro- 

 metric height ofJloulouk* 29"73. The temperature of the 

 mercury was unfortunately not observed. We may, however, 

 without falling into a great error, regard the above barometric 

 height as reduced to + 14° Reaum. This result confirms are- 

 mark made by M. Erman, jun., on the barometric height of 

 the sea of Okhosk. See Poggendorf's Antialcn 1829, No. 10.
