On the cruise in 1878 the reading of the piezometer 
was regularly verified, by comparison with the Standard- 
Thermometer, and the instrument invariably found un- 
changed. 
The pressure-correction was determined in 1878 by

Casella-Buchanan No. 46. 
On the 8th and 9th of May 1878, the millimetre- 
scale, on the minimum-side, was compared with the Stand- 
ard-Thermometer, at the Meteorological Institute in Chri- 
stiania. In the following Table t is the temperature, 
according to the Standard-Thermometer, m the reading 
of the Casella-Buchanan, both beg the means from sev- 
eral readings. By the formula 
m=m + at + Pt?, 
I computed by the method of the least squares the 
values of the coefficients m,, «, and $. The values of m 
computed by the formula with these values are entered in 
the Table under m. comp., and their difference from the 
observed in the Column Z\.
