part of the H-curve for 0» 30"—1* 30" p is missing. 
Readings taken as far as the registering part allowed do 
not show any large deviations, and slight departures from 
the normal are not reliable on account of the above mentioned 
disturbance; henee no conclusion at all shall be drawn from 
the magnetograms. 
Total Eclipse of the Sun of May 18, 1901. 
Course of central line: Mauritius, Sumatra, Borneo, New- 
„Guinea. The preliminary results drawn from the observations 
taken at Karang-Sago and Betavia have been published in 
this journal (Vol LXI, p. 173) !), but now, after the 
appearance of BAUER'S paper containing all the observations 
taken in international coóperation during the eclipse, it is 
necessary to treat these Karang-Sago- and Batavia observations 
anew.

Declination. 
In order to have a normal curve to compare with the curve 
of the eclipse-day, Bauer makes use of the registrated values 
on the 17*", because that day was fairly quiet and also because 
he had received fifteen minute readings. 
But the 17 was not magnetically normal, as may best
