VIII. A Delineation of the \ Tranjit of Ve- 
nus expeSled in the Tear 1769, by Mr . 
James Fergufon. 
To the Right Honourable the Earl of Macclesfield, 
Prefident of the Royal Socie'y. 
My Lord, 
Read Feb. 10, y Beg leave to prefent to the Royal So- 
1 ? 6 3 * y c j et y a delineation of the tranfit of 
Venus in the year 1769 [Tab. I.] which will be a much 
better tranfit for difcovering the Sun’s parallax than 
that in 176 1 was. 
Although I have only mentioned Wardhuys in Nor- 
wegian Lapland, and the Solomon ifies in the great 
South Sea, as proper places for obferving that tranfit ; 
yet I am feniible, that any other place near the north 
cape will be juft as well for the northern obfervers; 
and Tuberon’s Ifie, or St. Bernard’s, or the Fly 
lilands, in the great South Sea, will anfwer as well 
for the Southern. 
Although it cannot beexpedfed, that any delineation 
can be fo exact as calculation, yet I hope this projec- . 
tion will be found to come very near the truth j and 
am, with the higheft refpedt, 
My Lord 
your Lordfhip s 
and the Royal Society’s 
moft obliged humble fervant 
James Fergufon.
