MIR. Abbott with the aid Of Men3auaa.
detected the hea of the corona probably
for the first time. Observations with th.
bolometer showed that the corona gave
positive indication of heat as c"ola.a..
with the noon. This heat, though certain
was, however, too Slight to be su5-div"el
by the dispersion OF the prism, with ts
means at hand.
NO attempt to clearly examine .H'
plates taken for intra-meFcUrial pIa1'
has yet been possible. II is, o"a-
yer. doubtful if II very faint objects
will be found in consideration of tae eu#-
siderable sky Illumination during totlI'E.
However, Pleione and many fainter
stars in the Pleiades were plainly seen
on one Of the plates.
con the whole the expedition may .aHH
be considered as very satisfactory IN
