_ On reviewing the above statement, it 
would appear that, of the first hundred 
and two papers in the Spectater, fifty- 
nine were communicated by Addison, 
thirty-six by Steele, and seven by occa- 
‘sional correspondents : viz.— 
Nos. 1 to 6. ; 
. Three by Addison. Three by Steele. 
Nos. 1, 3, 5. Nos. 2, 4, 6. 
Nos. 7 to 31. 
Sixteen by Addison. Seven by Steele.

duced the original possessor of this copy, 
like many others, to discontinue taking it 
in. ‘“* Now every single half sheet pays a 
halfpenny to the Queen,” says Swift ina 
letter dated Aug. 7, 1712. “ The Observa- 
tor is fallen; the Medleys are jumbled to- 
gether with the Flying Post ; the Examiner 
is deadly sick; the Spectator keeps up and 
doubles its price.’ Addison has made this 
tax the subject of an excellent paper (No. 
445), in which he humorously alludes to 
the prevailing mortality among his brother 
authors, and very aptly terms it, according 
to the suggestion of “a facetious friend,” 
the full of the leaf. Yn this paper he states 
that, if the sale of the work is not injured by 
the addition of the halfpenny stamp, the coun- 
try will ‘‘ receive five or six pounds a-day 
by the labours” of the Spectator. From 
this statement it appears that, at the very. 
lowest calculation, upwards of two thou- 
sand four hundred copies of the Spectator 
were put into daily circulation at the time 
when this tax was originally imposed. But 
the number was afterwards considerably re- 
duced, no doubt in consequence of the in- 
ereased price. “ I once heard it observed,” 
- says Dr. Johnson, (Life of Addison) ‘ that 
the sale may be calculated by the product 
of the tax, related in the last number to 
produce more than twenty pounds a week, 
and therefore stated at one-and-twenty 
pounds, or three pounds ten shillings a day : 
this, ata halfpenny a paper, will give sixteen 
hundred and eighty for the daily number.” 
ence, then, it appears that in little more 
than four months after the imposition of the 
tax, the number of subscribers was reduced 
at least seven or eight hundred.

N.B. The above List has been made out 
from Tonson’s edition of 1744; but the 
signatures often vary in the different edi- 
tions. ‘In Bisset’s edition, for instance, 
No. 53 has Steele’s editorial mark (R) 
atlixed to it; and Nos. 60 and 95 are with- 
out any signature. 
Thus far the contributions of Addi- 
son and Stecle were furnished with great 
irregularity ; but, on a comparison it will 
be seen that Addison’s papers greatly 
exceed in number those of Steele, and 
consequently give him a title to at least 
an equal share in the profits. It will 
be my object, in some future communi- 
cation, to prove (what, I believe, has 
never been before attempted) that the 
remaining four hundred and fifty-three 
papers, almost without a single devja- 
tion, were supplied in equal numbers by 
Steele and Addison, with the assistance 
of their respective friends. W.

CERTAIN IMPORTANT PROPERTIES of

ASES are atoms in motion. 
The motions are local and cir-. 
cular, for as atoms are the objects of con- 
sideration, and as space is full of similar 
atoms, so atoms propelled or projected 
among a plenitude of ators would be 
deflected into. circular orbits, whiclr 
orbits would be as the momenta of the 
atoms affected. 
But bodies moving in one direction, 
exhibit no force in a contrary or lateral 
direction.
