Abstract
ORBITS OF BINARY STARS.—In addition to elements of O. ∑. 235, which apppear in the recently-published “Handbook of Double Stars,” Dr. Doberck has lately investigated orbits for the binaries 4 Aquarii and μ2 Herculis, stars for which no similar computation had been previously made. He assigns a period of 129.8 years for the former, the passage of the periastre at 1881.80, and for the latter a period of 54.25 years, the periastre at 1877.13. The elements give the following angles and distances:—
