Efter Formelen beregnedes en Tabel for de til hver

Resultatet opstilledes til praktisk Brug i grafisk Form.

Under Rejsen i 1878 sammenlignedes Casella-Buchan- 
ans Thermometre, oftere med Normalthermometret og 
fandtes altid uforandrede.

Mean of Å = MF = + 0.25 mm. = + 09.030. 
According to the formula, a table was computed 
for the values of m, corresponding to every degree from 
— 2 to + 5, and the result set down, for practical pur- 
poses, In a diagrammatical form. 
On the cruise in 1878, the Casella-Buchanan ther- 
mometers were frequently compared with the Standard- 
Thermometer, and always found unchanged.
