Computation had shown that the shadow would reach the Dutch 
eclipse-camp about 15 seconds later. 
In the beginning of May the English astronomer NEWALL, who 
was stationed at Sawah Loentoh, sent notice that he had been informed 
by the Nautical Almanac Office at London that the duration of totality. 
at Karang Sago would be 6m 22s instead of Gm 32s. It was decided, 
to be on the safe side, to shut all cameras on the 380" second after 
the beginning of totality. 
The programme was for the greater part promptly executed on the 
18th of May. The sky was however rather heavily clouded, and the 
various observations and exposures have all experienced more or less 
the disturbing influence of the clouds. Unfortunately, moreover, the 
nervousness of one of the assistants has made the results of the 
small spectrograph entirely useless. 
Owing to the clouds it was not possible to observe the sun’s cresc- 
ent of 45°; the last warning sign was given by the look-out. 
Totality commenced 0419™55s (local time) and ended 0'26™16s; 
the duration therefore was 6™21s. The computation according to the 
Nautical Almanac gave Ok 19m58s for the beginning and Oh 26m 308 
for the end of totality, and therefore 6™ 32s for the duration. 
Shadowbands have not been observed; besides Venus and Mercury 
only Aldebaran and a few stars in Perseus were visible. As a con- 
sequence of the rather heavy clouds it was not nearly so dark during 
the eclipse as had been expected, so that the lamps which were 
kept ready have not been used. 
Immediately after the eclipse it was known that the spectroscope 
and the small spectrograph had given no results. On developing 
the plates it also appeared that the exposure with the large spectro- 
graph was an entire failure. 
Before mentioning the results of the astronomical and physical observa- 
tions — the magnetical and meteorological observations are being 
discussed at Batavia — we shall finish the history of the expedition. 
On the 2274 of May Mr. Kerxuorr arrived at the camp with 
the plate exposed by him at the northern limit of totality: unfor- 
tunately this plate too brought a disappointment. Apparently the 
instrument had been adjusted correctly, but by a misunderstanding, 
and in consequence of the fact that the northern limit was actually 
further North than had been! expected according to the computa- 
tion, the moment of observation was not well chosen: the observer 
failed to get the phenomenon of the flash and photographed the
