# Further Observations upon Algol. By the Same **Author(s):** Palitch **Year:** 1784 **Journal:** Philosophical Transactions of the Royal Society of London **Volume:** 74 **Pages:** 2 pages **Identifier:** jstor-106572 **JSTOR URL:** --- III. Further Observations upon Algol. By the same. Read January 15, 1784. Oct. 20th, Palitch saw Algol nearly at its greatest obscuration, at 3 o'clock in the morning. Oct. 22d, near 12 P. M. he observed it again in the same state. Oct. 25th, at about 9 P. M. it appeared to him like a star of the third magnitude. He was prevented by clouds from making long observations; but as all those he has had opportunities to make, indicate a period somewhat longer than that of 2 days 20 h. 51' he is inclined to think that half the difference between that period and his own, viz. 2 d. 20 h. 52' will come very near the truth.
