June 8, 1750. obferved in Surry-ftreet in 
the Strand ; by Mr. John Catlin and Mr . 
James Short, F. R. S. Likewife an Obfer- 
vation determining the Longitude of King- 
Eon in Jamaica. 
Read Nov. \ T 7 E expe&ed to have feen the Moon 
V V rife cclipfed before the Setting of 
the Sun j but were prevented by Clouds. About 
half an Hour after 9 o’ Clock, we faw the Moon
