Literary and Philosophical Intelligence, 
[Dec. 1, 
which has been suppressed on the Con¬ 
tinent, will be published^in a few days, 
with Memoirs of the Author’s Life. 
Miss JoA^■XA Baillie has nearly 
ready lor publication the third volume of 
her Series of Plays on the Passions, 
Memoirs of the Life of Prince Potem- 
bin. Field lilarshal in the Service of 
Russia during the Reign of the Empress 
Catharine, are in the press. 
New editions will shortly be published 
of Madame de Genlis’s Historical Ro¬ 
mance “ Madame de Maintenon, pour

The Rev. Mr. Dibuin has completed 
the second volume of his Typographical 
Antiquities of Great Britain, which is 
expected to be published in' January 
1812. It contains 78 wood-cuts, some 
of them of a very spirited and uncom¬ 
mon nature; also four copper-plate en<- 
gravings of types ; and of three portraits, 
viz. John Moore, Bishop of Ely, A.I>. 
1707 ; Tnomas Martin, of Palgrane, Suf¬ 
folk; and Dr. Askew , M. D. of which 
latter no print was ever published. The 
present is taken from the original paint¬ 
ing in Emanuel College, Cambridge. 
The volume contains 640 pages, rather 
closely and elegantly printed hv Bulmer 
and Co. and hot-pressed. The copies 
on LARGE PAPER are all bespoke.

gress in a new novel, to be entitled Tem¬ 
per, or Domestic Scenes. 
A third volume of Bishop Horsley’s 
Sermons is in the press.

Memoirs of the Kings of Spain of 
the House of Bourbon, from the Acces¬ 
sion of Pliilip the Fifth to the Deatli of 
Charles the Third, 1700—1788 ; with an 
Jntrodu.ction relative to tlie' Goverr.ment 
and State of S^iabn; drawn from origi¬ 
nal documents and secret papers, many 
of wliich have never beibre been pub-

Mr, 'f. Sheldrake has, we are in¬ 
formed, mane an important discovery in 
tnecbanics, which it is hoped will prove 
liighly beneficial, by improving the effect 
of every machine into which it can be 
introduced. By tiie new application of 
a principle wliich was well known to the 
ancient mechanics, (though so complete¬ 
ly lost to the moderns that some have 
been willing to deny its existence,) he 
is enabled to produce either simple or 
compound machinery, which has either 
more power, more velocity, or both 
united, as the subject may require, which 
is comprised m less space, and is set in 
motion with less moving power, whether 
of animals, wind, water, or steam, than 
the machinery in common use. The 
simplicity of the parts, and numerous 
comhinations of which they are suscep¬ 
tible, render it probable that these prin¬ 
ciples may be applied to many ot the 
engines that are now' used for numerous 
purposes, the inventor has applied it to 
the following; 
1st. A capstan for naval and other pur¬ 
poses, which is allowed by many officers is 
the navy, and captains in the merchants ser¬ 
vice, who have seen it, to have none of the 
inconveniences ot the capstans that are now 
in use; to have greater pow’ers, and, there¬ 
fore, to periorm its work with fewer hands 
and in less time than any other capstan. 
2dly. A windlass, which possesses all the 
powers of the best windlasses m present use, 
with powers peculiar to itself, wnich render 
it equal to the capstan in effect, without oc¬ 
cupying more room than the common wind- 
hss. 
odly. A simple bat powerful movement, 
applicable to work the chain or commoA 
pump on ship-board, and in other situations, 
so as to deliver more water in less time, and 
with less moving power, than can be cone in 
the usual way. 
4thly. A portable crane, of similar dimen* 
sions, but much greater power, than that 
which is in general use. Of the superiority 
of this invention In compound machinery, 
the following example -may be produced A 
gentleman has a chaff-cutter, with which 
one horse works tw'O cutters ; the horse turns 
a cog-wheel of 121 teeth j ibis gives motion 
to a 'Smaller one of 20 teeth ; the axis of 
this wheel turns a larger, over which a beard 
passes into the iort above, and gives motion 
to the axis-which turns the flies that ksep 
the cutters in motion. I he opinions both 
of scientific and practical men differ as to 
the diminution ot power occasioned by fric¬ 
tion in machines ; but, without entering into 
that question, it may be sufficient to observe, 
that there is in this machine the friction of 
three axes upon their centres, and of 141 
teeth upon each other. 
*—In the design substituted by Mr. S. 
there are but two wheels hesines the 
flies, consequently there are but two 
axes ; the two ulieels contain but 2^ 
teeth; of’ course, whatever may be the
