a 
MR. CHARLES SEWARD’S (LANCASTER), for 
Improvements in the Construction of 
Lamps. 
HE reservoir of the oil may be made 
of any shape, so that it is very shal- 
low, or at least as shallow as it conveni- 
ently can, in order that the oil may be al- 
ways near the flame, and haveas littleas 
possible to ascend upthe wick: the body 
of the lamp should be madeno larger than 
to contain a sufficient quantity of oil for 
each time of burning, Vhetube that con- 
tains the wick is flat, and reaches to the 
bottom of the lamps and in order to give 
room to the wick, a little on one side of 
the wick-tube is cut away, or doubled up 
at the bottom. The advantages attend- 
ing this construction of the tube are, that 
the oil is warmed and kept from coagula- 
ting, especially that part of it which im- 
mediate(y surrounds the wick, and is in 
contact with the tube; which, in conse- 
quence of its conducting power, soon be- 
comes warm throughout its whole Jength, 
In a tube of this kind, the wick is not lis 
able to slide down, and extinguish the 
light: it is soldered, or otherwise fixed 
into a small round plate of tin, brass, or 
other metal, the edve of which rests upon 
a shoulder on the inside of a brass screw. 
The chimney, or lamp-glass, is not much 
different trom those alreatly in use, in 
some improvements of the érgan lamp ; 
itis placed about a quarter of an inch 
above the top of the wick-tube, leaving a 
space from the bottvm of the chimney, to 
the top of the brass screw, of about half 
an inch for the admission of air: the chim- 
ney is supported by a wire of metal, capa- 
bie of springing an opening so as tu ein- 
brace the lamp-glass. 
After Mr. Seward’s directions for using 
the lamp he enumerates the improve- 
ments which he claims exclusively as his 
ewn. 1. The additional length of the 
wmick-tube, or its reaching to the bottom 
of the lamp. The contrivance at the 
bottom of the ae -tube, for giving room 
to the wick, and preventing it from sliding 
down. 3. The additional width of the 
wick-tube. 4. The shape of the chim- 
ney or lamp-glass.~ 5, The manner of 
placing the chimney, or its application 
to lamps of any construction. 6. The 
manner of supporting the same, The ad- 
vantages of these lamps are enumerated 
by the patentee, who says, they will burn 
the most common oil without the least 
smell or smoke, and give aclear and bright 
light. They may be used inany situation, 
and are equally adapted for the manufac- 
tory and drawing room. ‘They are also 
very simpie, readily managed, and capa- 
ble of assuming the most elegant forms. 
Remarks.—We cannot help obser- 
ving that Mr. Seward has claimed more 
than he can well defend, if put to the 
test. From the figures attached to the 
specification, we are pretty certain that 
the shape of the chimney has no claim to 
novelty ; nor is there suflicient novelty in 
the mode of supporting it, to justify aa 
exclusive claim. We heartily concur with 
him in recommending the chimney to be 
of roughened glass.

MR. SAMUEL CRACKLES (KINGSTON UPON 
HULL), for & Method of manufacturing 
Brushes frou Whalebone. ° 
THe takes bone, which comes from the 
mouth of the whale, and having cutit into 
lengths of nine, twelve, or eighteen inches, 
boils or steeps 1t in water for such a length 
of time, as the nature of it may require, to 
make it soft and flexible. In this state it 
may be cut with a plane, knife, or other 
sharp instrument, into thin shavings, 
slices, or substances, which may be split, 
cut, or torn, by having lances fixed in 
front of the plane, knife, &c. into smalk 
pieces resembling bristles ef all sizes, and
