Dear Sir, The account that has been lately given of the regular variation of Algol's light, and the notice astronomers have been pleased to take of it, are well known. It is natural therefore to suppose, that the relation of other similar phænomena may also meet with the same favourable reception. Of this kind is the following, which I beg the favour of you to present to the Royal Society. On the 10th of September, 1782, whilst my attention was directed towards that part of the heavens where β Lyræ was situated, I was surprised to find this star much less bright than usual, whereupon I suspected that it might be a variable star: my suspicions were afterwards confirmed by a series of observations, which have been regularly continued since that time, and which will presently follow in their proper place.
