SIR NORMAN LOCKYER AND OTHERS ON THE 
A 5" X 4" camera, with Zeiss lens, operated by J. Collins, Chief Stoker, was also 
utilised for photographs of the corona. This was fixed in a convenient position, and 
liad no arrangement for following the sun during exposure. Three exposures of 
15 seconds each were made during totality, and one photograph shows very clearly 
the form of the corona and the relative lengths ot the four streamers. On this 
negative the diameter of the sun is 0‘05 inch, and the longest streamer, in the south¬ 
west cjuadrant, extends 0‘25 inch from the moon’s limb. Photographically, therefore, 
this streamer was five lunar diameters in length. Another exposure of 10 seconds, 
5 seconds after totality, shows the crescent strongly solarised, and a faint representa¬ 
tion of the corona on the opposite side. 
A 5" X 4" folding Kodak, operated by J. Kearney, Leading Stoker 1st class, was set 
in a position to include the corona and a portion of the wall of the fort in the field of 
view. Three exposures were made for periods of 20 seconds each. The first began 
just after totality had commenced, and gives a good representation of the corona— 
the two longest streamers extending only one lunar diameter. The second photo- 
gra})h shows clearly the lower corona, notwithstanding the fact that part of the sun 
had begun to appear. During the third exposure the camera was slightly shaken, so 
that the image is duplicated. 
Two cameras fitted with instantaneous shutters were set up with the view of 
photographing the shadow passing over the landscape in case its boundary should be 
sufficiently well defined. One was a 7^ X 5, and the other a half-plate, and they 
were operated respectively by E. Gyngell, A.B., and H. Childs, Chief Stoker. It 
turned out that the shadow on its approach appeared very gradually, so that the 
plates exposed simply resulted in under-exposed photographs of the general landscape 
with no features of Interest. 
The images of the sun seen inside the various observatories which were covered 
with matting were so striking throughout the preparations that it was decided to 
attem})t to photograph them during the partial phases of the eclipse. 
A quarter-plate camera for this purpose was accordingly placed in charge of 
E. Cross, Leading Stoker 2nd class. A liamboo screen was erected, with its plane 
roughly perpendicular to a line directed to the sun, and behind this a white cloth 
was s})read to receive the images. Three successful exposures were made with this 
Instrument. 
Shadow Phenomena. 
The party which was organised for the observation of the shadow phenomena other 
than the “ sliadow Ijands ” was in charge of Lieutenant Blackett, who reports as 
follows :— 
“ The observers state that the approaching shadow could not be seen, though 
carefully watched for. During totality the boat with mast and large flag could
