An Observation of the Eclipse of the Moon, Dec. 2], 1740, at the Island of 

 St. Catharine on the Coast of Brasil. By the Hon. Captain Ed. Legge, F.R. S. 

 N°462, p. 18. 



Capt. Legge observed that this eclipse of the moon began very nearly at 7^ 

 5"" ; but the horizon being hazy, he could not observe exactly the beginning : 

 however, it ended exactly to a moment at 9^ 50"". 



This eclipse was observed at the island of St. Catharine, on the coasts of 

 Brasil ; and the Captain places the island in latitude 27° 30'. Mr. Gael Morris 

 calculated the said eclipse ; and the middle of it, apparent time, at Green- 

 wich, was 11^ 44™ 50» 



By the Captain's observation, supposing the beginning exact ... 8 27 30

 Capt. Legge observes, that in attempting to pass Cape Horn, they thought 

 themselves to have been more to the westward than they really were: by which 

 mistake, turning too soon to the north, they fell in with high lands, and met 

 with those misfortunes, which, if they had kept out more at sea, might pro- 

 bably have been avoided. By comparing the longitude at St. Catharine's as 

 above settled, with Senex's maps, the coasts appear to be placed about 6 de- 

 grees too much eastward ; and if the other parts of America about the Cape are 

 laid down as faultily in the charts, this error will probably account for their mis- 

 fortunes.

The mercurial thermometer abroad, was last night, at 10 o'clock, 20° above 

 the freezing point ; which is higher than it was 16 mornings of the 31 in May 

 last, and higher than in any morning in April, one excepted.
