The next part of the Count’s invention 
is the elastic cable,for stopping the ship or 
other vessel at sea, in order to calculate 
the alteration that such current can oc- 
casion on the course of the ship, as these 
elastic cables can be used in a sinall 
seale, with a boat, as well as with the 
ship. Hence may be calculated the course 
of the ship. 
The Count deduces from the course of 
the ship the lee-way, which is accounted 
fer in thisinvention for the longitude by 
the means of a little glass-tube, such as 
that fora barometer. This glass-tube is 
fixed across the ship, to a little opening 
or valve on each side, very little under 
the level of the water: the centre of that 
rises perpendicular along the frame of the 
hydroscope, where a scale expresses the 
deyree of the lee-way of the ship by the 
water rising in that perpendicular glass- 
tube; in the proportion of the lee-way.

veyance of water, &c. Mr. Bell has ob- 
tained a patent for tubes of porcelain 
pottery, and other compositions which 
are vitrifiable, and not liable to corrosion 
or decay. These tubes are formed in 
such a manner as that their ends shal! fic 
one within the other, and they are then 
made water or even air-tight by means 
of cements. It is recommended by the 
patentee, that the pipes should be en- 
closed in cast-iron pipes, or cases, to de- 
feud them from breaking -hy external ac- 
cidents, and from bursting by the internal 
pressure of the water. Mr. B. notices 
compound metals as being less corrosive 
than the real metals of which they are 
formed, and therefore adapted to the same 
use as his porcelain tubes: also tubes of 
thin wood, boiled or charred, for all 
which he clans the originality. 
Ohservation.—We suspect he claims 
more than, if put to the test, hecan jus- 
tify: we have seen potiery tubes made 
use of to condact water from the roofs of 
houses, we thik, betore this patent was 
sought for; and thm wooden tubes, 
though, by charring, less liable to cor- 
ruption, would be very inadequate to re- 
sist the pressure of water coming from 
any height; we doubt if the different ex~ 
pansibility of the iron and porcelain 
would not occasionally be fatal to the 
latter.

Six Serious Glees, or, Hymns, for Three Voices, 
with an Accompaniment fer the Organ or 
Piano-Forte. Composed and dedicated to 
Alexander Anderson, Esq, by Mr. Fobn Ross, 
of Aberdeen. 103, 6d. 
HE words of these compositions are 
from the works of Dr. Watts, and 
are, properly speaking, hymns; we are 
therefore at a loss to conceive why Mr. 
Ross has given them thé appellation of 
glees. Ilymns they really are; and the 
appropriate character of the music proves 
that Mr. hj. considered them in that 
light while he was composing it. The 
melodial part of the compositions is, ge- 
nerally speaking, highly pleasing, and the 
combination every where correct and full; 
while the accompaniment is arranged 
with judgment, and greatly calculated to 
accommodate those who are unused to 
performance from more than two staves. 
Air Fantasque, for the Piano- Forte. Composed 
by Fulian Busby, Mus. Bac. Oxon. 25. 
This air is written to the title; but 
though fantastical, it is by no means ex- 
travagant. Oddity without inconsisteney,

and surprize without discordancy, or in- 
connection, have obviously been the aim 
of the young composer, and he has suc- 
ceeded. Much natural beauty of idea is 
blended with the peculiar character of 
the composition; and the effect. of the 
whole evinces abundant of talent, as weil 
as hich cultivation of ear. 
The favourite Ballad of ** Auld Robin Gray,” 
harmonized for Four Voicesy with an Accome- 
paniment for the Piano-Forte.. By Dr. Fobn 
Clarke, of Cambridge. 
Dr. Clarke’s harmonization of this old 
and justly popular air is conducted with 
that science and knowledge of choral ef- 
fect already so well evinced in many of 
his former productions. The two grand 
objects in view in an arranvement of this 
kind are, to give the greatest possible 
fulness to the harmony, and to make the 
internal parts sing well. These requisites 
the doctor has accomplished, and thereby 
given to “ Auld Robin Gray” not only a 
novel but a more attractive shape than it 
possessed before, :
