That the rays of light, by which we are made fenfible of
objects, make their way to the organs of fight in right-lined di-
rections, is evident from a molt iimple experiment: for, if the
bore of a tube or pipe be as much curved as is equal to the di-
ameter of the bore, nothing can be feen through it; or if one
objeCt handing before another of equal magnitude on the fame
line, be viewed by a perfon ftanding on that line, the laft will
be hid, provided they both ftand upright. I fimply mean, if
the fhafts of two columns of equal diameters were placed up-
right, and a fpeClator were ftanding upright on a line palling
through the centers of each fhaft, the laft one could not be feen;
but if vifion, or the faculty of feeing, were performed by rays
of light in curved directions, perhaps this would alter the cafe,
but not for the better, as I am certain that the conftruCtion of
our eye, and the way in which we, at prefent, difcover objeCts,
are the perfect productions of Infinite W-ifdom.
From what has been faid and referred to in the figure, I
prefume that the reader is not altogether ignorant of thefe two
