The preliminary remarks summed up the results OF
the former lecture on the same subject, When the
n,jests and nlnisersof religion were also those OF
science; when, in the panly days Of Arabic and
Eovtan learning arose the watchtoWers OF astro-
nomcal science
AS Greece arose and took a place among the most
polshed nations of the world, cosmology became a
fayorite study of her students and men of science,
and was openly, freely and thoroughly discussed,
whereas in Egypt it was only known to the learned.
Those of the Greeians who had studied in Egypt pri
marly brought it into vogue. Up to the fifteenth
century it had little advance. Nv
From the time of Copernicus, in the fifteenth cen
tuly, modern astronomy had its being. In the
eighteenth century the law of grayitation had its
BIRTH and science and fact thenceforth struggled for
ethe presidency. There are two great landmarks in
modern astronomy: the Mechanique Celeste, by La
place, and the discovery Of new planet by an Ita
ian philosopher.
Astronomy had begun to be of service to maritime
pursuits in the fifteenth century, but not until the
present did astronomy reach that point when further
discovery in that department, or for any practical
end, useless. Scientific culture, however, demands
further progress that the undeciphered secrets of
tlre may be learned and the mental faculties strength
ened. -*r :7.

The slightest influence, even drinking glass OF
water, is sufficient to marthe strctness OF an asro
nomical discovery Every motion OF shade, every
waving OF light, IS enough to render an observation

The theory of least squares used to the same end
taking the larger number Of calculations and bringing
them to the most probable result. The science OF
least squares IS toastronomy what logic IS to reason

finding gold in the street In Piatzi's case it was
