presented te us at Drury-Lane and 
Covent-Garden, that we had neariy 
determined to suspend our dramatic 
remarks tili the’ re-commencement cf 
the winter.season. But the various 
and striking powers of Liston, Terry, 
and Cooper, Madame Vesiris, Mrs. 
Chatterly, Miss Paton, and Miss 
Chester, as exhibited in Pigeons nnd 
Crows, the Rivals, the Way to’keep him, 
the Beggar’s Opera, the new operatic 
comedy of Sweethearts and Wives, the 
pleasant little musical piece of the 
Padlock, and the new and lively farce 
of Mrs. Smith, are too worthy obser- 
- vation not to claim our acknowledg- 
ment of the pleasure we have derived 
from their exertion; and our thanks 
in advance, for the gratification we 
anticipate from their further display. 
“Sweethearts and Wives” is the 
production of Mr. Kenny. As an 
operatic comedy, (that is, a dramatic 
vehicle for music,) this picce is enti- 
tled to the favourable reception with 
New Patents and Mechanical Inventions.

which it has been honoured. The 
characters, though not very novel, are 
variable and well sustained; the dia- 
logue is terse and animated; and the 
plot, though, we must say, nut very 
skilfully conducted, is far from being 
bad in itself. The development of the 
whole gyst of the business, before the 
end of even the first act, was highly 
inartificial, and proved so dangerous 
to the piece, that we trembled for its 
existence ; which certainly, but for the 
hearty zeal of Liston in the author’s 
cause, would have been of short dura- 
tion, admitting even that, without his 
exertion, it would have been heard 
through. However, it is due to Mr. 
Kenny to say, that, had that unfortu- 
nately been the case, the public would 
have debarred itself from the enjoy- 
ment of some interesting, scenes, and 
much easy and pleasant dialogue,— 
features with which ‘“ Sweethearts 
and Wives” as much abounds as any 
drama whatever of recent production. 
NEW PATENTS AND MECHANICAL INVENTIONS. 
a 
To Witttam Danieit, of Aborcarne, 
Monmouthshire, for certain Improve- 
ments in the rolling of Lron into Bars, 
used for making or manufacturing 
Tin-Plates. 
HIS invention consists of an im- 
provement in the mode of rolling 
iron to be used for tin plates, and con- 
sists in rolling the iron (to be used for tin 
plates) perpendicularly between a. pair 
of rollers, with grooves of different grada- 
tions, the iron being previously cut with 
a: pair of shears, or any other instrument, 
into pieces of four inches and a half 
square, more or less (but Mr. D. gene- 
rally prefers that size), the first groove 
in the rolls being so cut or formed as to 
admit each cf the pieces of iron (singly) 
to pass through perpendicularly, and the 
successive grooves in the rolls being such 
that the pieces of iron may come out of 
the last groove reduced to a proper 
thickness for tho future stage of the 
manufacture of iron for tin plates. By 
the means of rolling the iron perpendicu- 
larly, in the manner described, the inside 
of the picce of iron is brought to the 
surface, and the imperfection it contains, 
instead of being dispersed and intermixed 
throughont, is foreed to the edge and 
ends, ‘The quality of the iron for tin 
plates is thereby much improved, and 
the number of tin-plate wasters are 
thereby reduced,——Repertory, 
To JouN Gianstone, of Castle-Doug- 
las, Engineer and Millwright ; for an 
Improvement or Improvements in the 
Construction of Steam vessels, and 
Mode of propelling such Vessels by the 
Application of Steam or other Powers. 
This invention consists in axles or 
shafts passing through the sides’ of the 
vessel; {o these axles or shafts motion 
may be communicated in the usual way _ 
by steam or other moving powers ; 
second, that upon each of these axles or 
shafts, on the outside of the vessel, 
there be fixed one or more male or 
female stud-wheels, drums, or cylinders, 
adapted for one or more endless chains; 
Which chains are to pass over wheels or 
cylinders near the other end of the ves- 
sel, and are so constructed as to form a 
considerable curve on the side applying 
in the water, and to be completely kept 
from sliding on the wheels; thirdly, 
across these chains, floats, or paddles of 
wooll, or any other suitable material, 
are fixed at such distances, as will freely 
permit the application of the chains to the 
surface of the wheels or cylinders, and 
in such a manner, as to retain the floats 
or paddles ina position nearly perpen- 
dicular to the position of the chains to 
which they are attached; fourthly, the 
progressive motion is given the vessel by 
the action of the floats or paddles in the 
water, during the revolution of the 
chains
