SIR NORMAN LOCKYER AND OTHERS ON THE 
It thus appears that more stars were seen just before the commencement of 
totality than during the actual period of totality ; that is, they were logged as 
disappearing just before the total phase commenced. A similar observation was 
made l^y Admiral Don Ulloa in the eclipse of 1778.The body seen between 
Venus and Mars was certainly not a star, although its behaviour was similar to that 
of 6 Aquilse. Sir Norman Lockyer has suggested that it may have been a collision 
of meteor swarms in the sun’s neiofhbouihood. 
The chart summarisizig the observations of stars is reproduced on a small scale 
in fig. 4 (p. 171). 
Hand Spectroscopes. 
Three small integrating spectroscopes were provided for eye observations. Two 
of these were direct-vision pocket spectroscopes, while the third was an ordinary 
prism of 30“ attached to the end of a tube about 10 inches long, which was provided 
with a slit at the other end. 
Lieutenant Colbeck was in charge of these observations, and the preparatory 
work consisted of observations of the spectra of various salts when burned in a 
spirit lamp flame, in addition to joining in the general drills. 
Sir Norman Lockyer has examined the records, and suo-g-ests that Lieutenant 
Colbeck’s observation at 25 seconds before totality possibly indicates a faint 
continuous spectrum, witli the hydrogen C and F bright. Further, that the lines 
seen during totality were probably : 
Yellowish-green, seen by three observers—Corona line. 
Blue ,, ,, ,, -—Hydrogen line (F). 
Red, seen by

After totality the Fraunhofer lines reappeared in the following order 
Line in the orange (D). 
Lines in the green (? 6, e). 
Lines in the violet and blue (? F, G). 
Prisms for observation of Ping Spectra.

These observations were chiefly intended to sujDplement the photographic work 
of the prismatic cameras, by providing a record of the phenomena in the green and
