C. A. Young—The Solar Eclipse. 289 
rings. I looked most carefully for them, expecting to see 
them. Once about the middle of totality I thought I saw 
traces of a ring about where 1474 ought to be, but a second 
look did not confirm the impression. The continuous spec- 
trum seen during totality was somewhat wider than the moon’s 
disk, but I cannot say how much, nor can I tell just when it 
assumed the greater width. Before totality it was quite nar- 
row and the bright crescents projected on both sides beyond it. 
But I remember that in looking for the rings I expected them 
to be seen upon this spectrum and not to project beyond it. 
I did not take my eyes from the instrument during totality, 
my intention being to see these rings if there were any to see, 
and my first feeling when totality was over was one of failure 
because none had been visible.” 
Thermoscopie observations.—Mr. A. D. Anderson reports his 
observation with the thermospectroscope as follows: “ as 
the corona appeared the slit-tube (collimator) was pointed to it, 
the slit opened, the galvanometer balanced, and the lever which 
turns the grating moved so that the spectrum from the orange 
through the ultra-red traversed the face of the pile. When 
the extreme red was reached the lever was moved back to its 
original position. During totality the instrument was pointed 
four times to the corona, and four observations were made. 
The only result obtained was during the third observation when 
a decided deflection of the galvanometer index was noticed, in 
the direction indicating heat, from 54 to 57% on the scale, the 
index returning to its original position as the lever was mov 
past the point. A precisely similar and equal deflection oc- 
produced the observed deflection, it is equally difficult to ex- 
plain why the three other sweeps across the spectrum failed to 
show the same thing. 
elt iis proper that I should here add that the American Acad- 
€my of Sciences at Boston had placed at our disposal a consid- 
erable appropriation for this thermoscopic research ;_ thanks, 
however, to the industry and ingenuity of Professor Brackett 
i? Constructing our apparatus, the generosity of Mr. Edison in 
8lving us a tasimeter, the kindness of our railroad friends in 
the matter of passage and freights, and the liberal scale of the
