The column of rates for Kt—Hiw shows some considerable 
which cannot be explained by any progressive term and which 
pletely mask the effect of temperature. In the rate of Ivo—Hw 
uregularities 
almost com- 
the effect of 
temperature is very prominent (between 0%.2 and 0%.3 per degree) and the 
casual irregularities are smaller and of a different character, from which it 
follows that the irregularities in the column A¢—Hw are due to Kutter. After 
the return of the expedition all the three chronometers were kept going for 
some time in the Christiania Observatory without being touched; for Hiw 
and Jv a series of comparisons were available also from the the time imme- 
diately preceding the departure in 1893. Kutter arrived from Germany only 
some few days before the departure, but by the courtesy of Professor Neuv- 
MAYER the writer is in possession of a series of comparisons made from the 
beginning of 1893 in the Deutsche Seewarte.
