NEXT EASTER.

The following curious article regarding " Easter-day,
0345," is by Professor de Morgan :
" In an article which I have prepared for the next
►umber of the Companion to the Almanac,' I have dis-
•ussed the reasons why Easter day will next year fall,
n apparent defiance of the Act of Parliament, upon
:he very day of the full moon. But as an acci•
rental application which I have received (and I know
,hat the superintendent of the Nautical Almanac has

•eceived (Mother from a different quarter) makes me

.hink that the computers of almanacs will be puzzled,
'lnd that the useless discussion of 1818 (when the dis-
zrepency last occurred) will be revived, unless some one
mill forthwith state the reason of the difficulty, I re-
Nest that you will publish some of the conclusions
,f the paper to which I refer, which will in due
,ime appear in the work cited. And I hope that

bhe diify papers will give additional currency to
the same coneusions ; and I should recommend that

the same thing should be done in the almanacs'. Tbe
rule adopted in this country for finding Easter is that
A* the Roman. Catholic Church, as established at what
s called the Reformation of the Calendar by Pope
Gregory the Thirteenth, in the year 1582 The au-
hority for this rule is contained in the papal brief of
March Ist, 1582, in which reference is made, for all ex-
p!anations, to the then forthcoming work of the Jesuit
Cluvius, to whom both the adjustment and explanation
dr the Calendar had been intrusted. The British Par •

tia,ment, in adopting the rule of Clavius, made two mis,
Sakes in the explanation of that rule. Their explana-
ion is, that Easter Sunday is the Sunday after the full
Goon which comes on or next after the 21st of March,
ind that if the full moon fall 'on a Sunday, Easter Sun-
lay is the next Sunday.
The two mistakes are as follow :
"1. Instead of full moon,' they should have said,
fourteenth day of the moon, the day of new moon
ming reckoned as the first.' That Easter, as well as
the Passover, was always regulated, not by the full
';noon, but by the fourteenth day of the moon, is of the
attriost historical notoriety. And Clavius says that
none but a few who fancy themselves sharpsighted ever
imagined that the fourteenth of the moon and the full
• moon were the same in the Church of God.'
"2. Instead of the moon' of the heavens, they ought
to have said the moon of the calendar,' which is a very
,lifferent thing. The moon of the calendar is not even a
mean, or uniformly moving moon to which astronomers
refer the real moon ; but differs from it intentionally and
.vowedly, by two classes of arbitrary alterations, the
.irst cuss intended for simplicity of calculation, the
second for avoiding the possibility of the Christian Easter
falling on the actual day of the Jewish Passover.
" In the year 1845, the fourteenth day of the calendar
'noon falls on Saturday, the 22d of March, whence Easter
s rightly made to be Sunday, the 23d, according to the
law both of the Roman and English Churches, though
the English statute does not well explain its own method.
With regard to this country, it should be noticed that
this statute enacts that Easter shall be kept by the' ea-
:endar, tables, and rules' annexed to the Act; and these
igree with Clavius.
" Of course any one is at liberty, as many did in.lBlB,
to think that the statute should be altered; and cer-
tainly it would be worth while .to avoid misconception
by repealing the faulty definition, and substituting a
better one, in the Prayer-books of the Established
Church. But if any one should wish to advocate the
repeal of the rules, and the construction of new ones
agreeable to the existing definition, and astronomi-
cally true, he will perhaps pause when he finds that
his own system would sometimes cause it to happen that
St. Paul's. Cathedral must keep. Easter a week after

Westminster Abbey, and would very frequently make a
•.reek's difference between the festivals of the colonies
:Ind the mother country.—l remain, Sir, yours faithfully,

Mr. Bunn left London on Sunday for Italy, to
make engagements for the ensuing season at Drury-lane.
TRAFALGAR •SqUARE.—The Earl of Lincoln and
Mr. Young have introduced a Bill to provide for the care and
preservation of Trafalgar-square, in the city of Westminster.
It enacts, that Trafalgar-square, and all the works now being,
or which may be hereafter erected thereon, shall be vested in
the Queen's Most Excellent Majesty, her successors and heirs;
as part And-parcel of the hereditary possessions and revenues
of her Majesty in right of her Crown, within the ordering
and survey of the Court of Exchequer. The care and man-
agement of the square, and of all the Works therein, are vested
in the Board of Woods and Forests.
Ladies travelling, or temporarily subjected to any
deiiation of equable temperature, will find. in Rowland's
Kalydor a renovating and refreshing auxiliary, dispel-
ling the cloud, of langour from the complexion, and
immediately affording the pleasing sensation attending
restored elasticity of the skin. The distressing and
unsightly varieties of ' cutaneous eruptions are also
promptly eradicated by the Kalyclor. Spots, pimples,
freckles, dizcolourations, and sallowness, yield to its
specific qualities; and are succeeded by a smoothness
and transparency of the skin, gßing rise to sensations I
of the utmost pleasure and surprise. - Being univeraally
preferred, its consequent great demand excites the
cupidity of unprincipled shopkeepers, who give the title
of "Genuine" Kalydor to some compounds of their own
manufacture, of the most deleterious character, con-
taining mineral astringents utterly ruinous to the
complexion, and by their repellant action endangering
health. It is, therefore, imperative on purchasers, to
see that the words " Rowland's Kalydor" are, on the
vrtappet4; All others areltauduleut counterfeits-i
