notwithstanding Data.
When did astronomy have its begin
nings ON the carth2 There have been
many learned attempts to answer this
question. They all have led To the con-
clusion that long before the historic
period there was a large common stock
Of knowledge; SO large, in fact, that one
distinguished writer finds it simplest to
ascribe the origin of astronomy to the
teaching Of an extinct race: "Ce peuple
ancicn qui nous n tout appris-eXcepte
son nom ct son existence, his commeu-
tator adds.
Astronomy is older than the first re-
cords of any nation. In order that the
records might exist, it was first necessary

only case which | have been able to col

by a celestial phenomenon. The actions
Of the most ignorant savages during a to-

animals, throw much light on tho ques-

ages are appalled, by the disappearance
of the sun itself. while animals seem to
be concerned with the advent of dark
ness simply.

without compass or chart, bound for an
island three days sail distant. His
course would need to he 50 accurately

should find himself within four or five
miles of his haven; if he passed the low

can he little doubt but that he used the
sun by day and the stars by night TO
hold his course direct.
There must have been centuries during
which such knowledge was passed from
man to man by word Of mouth, woven
into tales and learned as a part Of the
lore of the sailor, the hunter or the tiller
Of the soil. No one can say low early
this knowledge of the sky Was PUT into
the formal shape of maps, globes or cata-
logues. EudoXus is said to have con-
structed q celestial globe b. G. 500.
Globes would naturally precede maps,
and maps mere lists or catalogues.
The prototype of all sidereal catalogues
is the Almagest Of Ptolemy "a. d. 1901,
which includes not only the observations
Of Ptolemy, but those of the great Hip
parchus CB. C. 120. 1t contains the
description of l,022 stars, their positions,
and their brightness. Here we meet for
the first time the name magnitude Of q
star. Ptolemy divides all the stars into
magnitudes-degrees Of brightness.
Sirius, Capella, are of the first magni'
tude; the faintest stars visible to the eye
are Of the sixth. But Ptolemy has gone
further, and divides each magnitude into
three parts. The moderns divide each
class into ten parts, that is, decimally,-
