bands ! ” An English pressman assured me that during 
totality “ every other Spaniard crossed himself and said his 
prayers,” and certainly the sense of relief expressed by many 
found voice in loud hurrahs, cheers and clapping of hands 
as sunlight returned. 
Of the effects of Nature I cannot speak. The gathering 
clouds made it impossible to say how much of the dullness 
was due to the partial phase as totality approached, but 
the darkness was not that of ordinary twilight. There was 
a weird unearthly gloom over the entire landscape. During 
totality the light was estimated to be rather more than that 
of full moon. Mr. Benson, who was engaged with the cameras, 
and made all the exposures, had no difficulty in seeing the 
small seconds hand of an ordinary watch. A horse close 
by us neighed loudly when the actual darkness fell, and 
Mr. Taylor, who was not engaged with instruments, assured 
me that its rider had difficulty in restraining it. 
Our photographs of the corona speak for themselves. 
The small one (shown by the Lecturer on the screen) was 
obtained by exposure for minutes with an aperture of 
f.8, and is reproduced for any value it may have as recording 
the distribution of green coronal light. Although exposed 
for nearly the whole of totality, its equivalent exposure was 
really only half a second, the green screen in normal sunlight 
increasing the duration of exposure some 400 times. 
Not the last important of our results is that we have shown 
what can be accomplished by apparently inadequate means. 
It might have been conjectured that it would have been 
impossible to carry out our programme without a driving 
clock. But the photographs we obtained show that it is 
possible to make a mount that shall be not only portable, 
but easily and quickly adjusted, and that a steady and con- 
stant pressure can be given to the tangent screw throughout 
the whole drive by so arranging the proportions of the screw 
that one grip of the hand, in the case of comparatively short 
exposures, covers the whole time. They also suggest that 
hand driving may be absolutely relied upon, at least for 
small instruments ; whereas a clock has been known to fail 
at the critical moment. There is no shift in the image, 
though the instrument was driven for 210 seconds. 
The larger photograph was obtained with the afore-named 
telephoto lens, working at f.88, and had an exposure of 15 
seconds. The camera was attached to the second mount,
