* Recalculated from Abbot & Fowle, /. Opt. Soc. Am., 5, 1921 (272). 
Through the generosity of Drs. V. M. SHpher and C. O. Lampland, the 
present data were obtained during the past summer, using the 40-inch re- 
flector of the Ivowell Observatory, at Flagstaff, Arizona, altitude 73,000 ft. 
Dr. Lampland personally operated the telescope, thus insuring speed and 
efficiency. It is a pleasure to record here my grateful acknowledgment 
for the many courtesies extended me by various members of the Observa- 
tory Staff.
