The Second Example. With falling Declination.

Upon the 16 of the same yeare I desire to know the Suns declination at noone) at Bantam and I find in these Tables upon that day for the length of England Lands end 2 degrees 40 minutes, that it decreaseth every day at that time of the yeare 24 minutes. Seeing then the Sun (as is sayd in the first example) cometh 8 houres sooner to the South at Bantam then at Englands end, I say doth the declination decrease 24 minutes in 24 houres, how much maketh it in 8 houres? it maketh 8 minutes from thence it is knowne, that seeing the Sonne runneth from the Meridian of Bantam to that of Englands End, and the declination falleth 8 minutes, and therefore at Ban∣tam is it 8 minutes more, even as these Tables declare. The declination of the Sonne on that day is at Bantam 2 degrees and 48 minutes.
