The breadth of the shadow, as marked on an ordinary map for ^le - 
with Variation, will not sensibly differ from that for Greenwich Unvaried Elements. 
30. The results of these calculations are laid down on the first map accompanying 
this paper, Plate XII. The large dots show the two possible positions of Ag.vthocles. 
The strong line shows the central |iath of shadow, and the faint dotted lines show he 
limits of the dark shadow, from Greenwich Unvaried Elements The inteiiupt 
line shows the central path of shadow from Elements ^a'-iation (the tom 
“Variation" signifying an increase of the Mean Argument of Latitude by O -0). 
other lines show the positions of the central path of shadow necessary for satistying 
respectively the four following conditions:-!, that the Northern bonnda.y of the 
shadow will touch the Southern position of Agathocles ; 2- that the Noit le.n 
boundary will touch the Northern position ; 3. that the Southern boundary will
