AVAIL myfelf of the permiffion you gave me, when I 
had the honour to meet you yefterday in the Drawing-room, 
by fending you the following fhort account, which was tranf- 
mitted to me. by Mr. CanzLex,. one of the Elector’s Libra- 
rians, dated Drefden.the roth of Ogtober. Patircu, a far- 
mer of Prolitz,‘a village in the neighbourhood of that Refi- 
dence, faw the greateft obfcuration of Algol on the 12th of 
September, at eight o’clock, P. M. On ‘the 2d and sth of 
Oétober he obferved the fame phanomenon again. On the sth 
the greateft diminution of that ftar’s light happened fome mi- 
nutes before feven, when he judged it nearly of the fize of a 
{tar of the fourth magnitude: it continued increafing in bright- 
nef{s till a quarter paft ten in the evening, at which time it had 
entirely recovered its ufual brillancy and fize. From his own 
ebfervations he eftimates the period of that remarkable phano- 
menon at 2 days 20 hours 53 minutes. 
I have the honour to be, &c.
