1822.) 
Lieut. MARSHALL is preparing for 
the press, a Naval Biography, to consist 
of genealogical, biographical and his- 
torical memoirs of all the flag officers, 
captains, and commanders of his Ma- 
jesty’s fleet, living at the commence- 
ment of the year 1822. 
The Number of the Journal of New 
Voyages and Travels now printing, 
consists of an over-land journey of a 
shipwrecked Englishman in the mari- 
time provinces of China, through dis- 
tricts hitherto unexplored by any Eu- 
ropean. The following Number will 
contain very interesting Travels into 
the interior of Africa, by the crew of 
the Sophia, by which it appears that 
Adams the sailor uever was at Tim- 
buctoo, and that Capt. Riley has made 
many.extravagant mis-stalements. 
Maid Marian, a Tale, in one vol. is 
in the press. 
A third edition of Headlong Hall is 
in the press. 
A very extraordinary discovery was 
a few years since made in Guatimala 
(Mexican Isthmus) of the ruins of an 
extensive city, which had for ages been 
covered with herbage and underwood. 
It has. since been accurately surveyed 
by a learned Spaniard, and drawings 
made of its curiosities. The originals 
of them have arrived in London, and 
will soon be presented to the world. 
Memoirs and select Remains of an 
only Son, are expected to be published 
some time during the ensuing spring or 
in the early part of the summer, by the 
Rey. THOMAS DURANT. 
Shortly will be published, illustrated 
with numerous portraits of historical 
characters, Monarchy Revived, being 
the personal history of Charles the 
Second, from his earliest youth to his 
restoration, comprising many curious 
particulars of his escape after the battle 
of Worcester and his residence on the 
continent. 
Shortly will be published, a legal 
and Constitutional Argument, support- 
ed by authorities, against the alleged 
judicial right of restraining the publi- 
cation of reports of judicial proceedings, 
as assumed by the Lord Chief Justice 
Abbott, at the trials of Thistlewood 
and others for high treason, and en- 
forced against the proprietor of the 
Observer, by a fine of 5001. By J. P. 
THOMAS, esq. 
The Works of John Home, Esq. with 
an account of his Life and Writings, by 
HlenRyY MACKENZIE, Esq. with por- 
traits and maps, will soon appear.

We are informed that when Sir 
WALTER Scorr has exhausted his 
inventive powers in novel writing, he 
purposes to direct his genius to the 
Drama, and exhaust his plans in that 
line: thus during his literary career, 
figuring successively as poet, novelist 
and dramatist. 
Accounts from Tripoli state, that the 
expedition under Mr. Beechy, into 
Lebada, was preparing for its depar- 
tnre: and, at the time they are prose- 
enting their researches among the ruins 
of antiquity, Captain Smyth is to sur- 
vey the North African coast. 
Sir Humphrey Davy has published 
the following general obseryations on 
the papyri found in Herculaneum. 
The Roman MSS. found in the Mu- 
seum, are in general compose of pa- 
pytus of a much thicker texture than 
the Greek ones, and the Roman charac- 
ters are usually larger, and the rolls 
much more voluminous; the charac- 
ters of the Greek MSS. likewise, with 
a few exceptions, are more perfect than 
those of the Latin ones. From the 
mixture of Greek characters in several 
fragments of Latin MSS. and from the 
form of the letters and the state of de- 
composition in which they are found, 
it is extremely probable that they were 
of a very ancient date when buried. I 
luoked ‘in- vain amongst the MSS. and 
on the animal charcoal surrounding 
them, for vestiges of letters in oxide of 
iron; and it would seem from these 
circumstances, as well as from the 
omission of any mention of such a sub- 
stance by Pliny, that the Romans, up 
to his period, never used the ink of 
galls and iron for writing: and it is 
very probable, that the adoption of this 
ink, and the use of parchment, took 
place at the same time. The earliest 
MSS. probably in existence on parch- 
ment, are those codices rescripti dis- 
covered by Monsignore Mai, in the 
libraries of Milan and Rome. I have 
tried several substances for restoring 
colour to the letters in ancient MSS. 
The triple prussiate of potash, used in 
the manner recommended by the late 
Sir Charles Blagden, with the alterna- 
tion of acid, I have found successful ; 
but by making‘a weak solution of it 
with a small quantity of muriatic acid, 
and by applying them to the letters in 
their state of mixture with a camel’s 
hair pencil, the results are still better. 
It is remarkable, that no fragments of 
Greek, and very few only of Latin 
poetry, have been found in the whole 
collection
