In the plate the curves for D, H and Z are plotted together 
with the normal ones. 
In the H-curve a slight wave occurs between 1» 30” p 
and 4^p; with a crest at 2^0" and a trough at about 3^ p. 
Perhaps this wave may be associated with the eclipse and 
accordingly the effect may be assumed to be 
an increase of H before | the maximum phase. 
a decrease ,, H after | 
The range amounts to about 4 y. 
The Z-curve shows a remarkable decrease of + 7 7 WALA 
1» p and 4^ p, which perhaps too may be regarded as an 
eclipse-effeet. 
Annular Eclipse of the Sun of April 6, 1894. 
Course of central line: Bengal, East-China, Beringstreet. 
Minimum distance from Zi-Ka-Wei + 13°, maximum phase

The magnetograms show that the eclipse-day was not 
very quiet, as was to be expected in a year of high solar 
activity.
