The position and magnitude of 1449 stars listed in "Seoung Kyung" (by Byung Kil Nahm, 1861) are compared with those in modern western star catalogues for their identification. 923 stars out of 1449 stars were identified within the range of accuracy. Δ α ≤ 20 s .0 , Δ δ ≤ 1 ′ .0 a n d Δ m = 0 o r ± 1 . When Δ α a n d Δ δ increased to Δ α ≤ 1 m . 0 , Δ δ ≤ 15 ′ .0 a n d Δ m = 0 or +1, 399 more stars could be included in the list.
An attempt has been made to re-evaluate the photospheric iron abundance by comparing computed, theoretical line profiles with observations. Our resulting abundance is found to be in good agreement with that of Garz and Kock (1969), when the logarithmic abundance of iron is taken to be 7.5.
The interpolation formula Chao-ch'a-shn devised for the Chinese calendar, Shou-shih-li, has been shown as the one of the 3rd order polynomial. Its 3 coefficients have been determined from the table of the Sun in Shou-shih-li. Its applications to the moon and planets are also briefly mentioned.
