No More Learning

“This was the first time,” says
the Spanish historian, “that in barbarous times the Republic of
Letters was invited to contemplate a great school of learning, - men
occupied through many years in rectifying the old planetary observa-
tions, in disputing about the most           details of this science, in
constructing new instruments, and observing, by means of them, the
courses of the stars, their declensions, their ascensions, eclipses, longi-
tudes, and latitudes.
