C. A. Young—The Solar Eclipse. 279 
Art. XXXII. — Observations upon the Solar Eclipse of July 29, 
1878, by the Princeton Eclipse Expedition ; by Professor O. A. 
Youne. 
THE Princeton expedition to the Rocky Mountains to observe 
the recent eclipse, was organized early in the year, and its ex- 
penses were mainly provided for by a liberal appropriation made 
for the purpose by the trustees of the estate of the late John 
C. Green. I have said, mainly, because we are also greatly 
indebted to the kindness of the managers of the Pennsy!vania, 
the Chicago and Alton, and Kansas Pacific Railroads, and to 
the American Express Company, for the free transportation of 
persons and instruments, to the authorities of the State of 
Colorado for the loan of camp equipage, and to the Western 
es. 
also under obligations to Mr. Edison, to Rutgers and Dartmouth 
par : 
myself, consisted of ten persons when we left Princeton on 
July lst. We were joined in Missouri by another, and after 
Astronomical Society was also with us as our guest, and 
odserved from our camp, and on the day of the eclipse we 
were assisted by several volunteers who came out from the 
city for the occasion. 
Triving in Denver on July 5th, we went into camp on the 
7th in rove on the bank of Cherry Creek about two and a 
half miles southeast of the city. Our position was determined 
by a triangulation made by Messrs. cibtay and McNeill, con- 
hecting us with several well determined points in the city.
