NOW In folar eclipfes the moft regular method of 
treating them would be to confidcr the vifible way of 
the moon from, the fun, as a line of continued curva- 
ture, which it really is ; and as it differs not greatly 
from a ftreight line, an arch of a circle may fafely be 
ufed for it. But’ to form a computation in the fpherc 
upon this principle would require a procefs fomewhat 
intricate j but all the particulars ufually inquired into 
in folar eclipfes may readily be affigned graphically with 
fcale and.compals after'this manner. •- 
Firft, find the time nearly of the conjunction of the
