Plotting the figure carefully from these notes, and then drawing the 
nearest possible coincident circle, we obtain results similar to those ob- _ 
tained by the survey of the Observatory circle at Newark. This is shown 
in PI. VI. In this figure the solid biack line of short chords running along 
the middle of the wall marks the actual line of survey, while the dotted 
line is the nearest approximate circle, the center of which is at the in- 
tersection of the two designated diameters.!. These diameters are act- 
tually surveyed lines, and relate to the line of chords. The middle of that 
running from d to d is at the intersection; but the middle of that run- 
ning from a to ¢ is about 2 feet from the intersection toward ce. 
The somewhat unexpected results to which allusion has been made: 
in reference to this and the Observatory circle are, first, that the figure 
is so nearly a true circle; and, second, that the radius is almost an ex- 
act multiple of the surveyors chain. Itis true that Messrs. Squier and 
Davis assert that this and some other inclosures are perfect circles, 
but their many errors in regard to dimensions, and our belief in the
