The tranfits marked with the fign * are partly vifible at Zon- 
don^ but thofe with the lign * * are entirely to be leen there. 
Note, that the fun's diameter at the afcending node of Mer- 
cury in the month of OEfoher is 32' 34'^ 5 and therefore that the 
greatefl duration of the central tranfit is 5 h. 29 m. but in April 
the lim's diameter becomes 51' 54'^ whence on account of the 
flower motion of the planet, the greateft duration is 8 h. i m. 
But if Mercury fhould fall oblicjuely upon the difk, theie dura- 
tions become fhorter in proportion to the diftance from the fun's 
centre 5 and that the calculus might be the more perfefl, the fol- 
lowing tables are fubjoincd, wherein are exhibited the half du- 
rations of thefe eclipfes for each minute of diftance feen fram the 
lun's centre, which added to, and fubftracled from, the moment of 
conjunction found in the former table, exhibit the beginning and 
end of the whole phaenoraenon.
