250 Literary and Philosophical Intelligence. [Oct. 1 ? 
burghead, one extremity of the Isle of 
Mainland, the largest of -the Shetland 
Islands, in 59° 52' North latitude, 
and 1° 28' West longitude. It is about 
twenty miles SW. from Hangcliff 
Head, on the Isle of Noss. The light 
will be visible to all ships sailing in the 
southern parts of the Shetland Islands, 
between Fouia island and Nosshead. 
The flame will be fixed, but accom¬ 
panied with reflector lamps ; the eleva¬ 
tion 300 feet above the mean level of 
the sea. At the distance of six or seven 
leagues, it will appear like a star of 
the first magnitude. 
IRELAND. 
The works for the construction of the 
Port of Dunleary, consist of two jetties, 
the eastern is already3000 feet in length, 
by 200 in breadth ; the western, com¬ 
mencing near the old port of Dunleary, 
is about 500 feet in length. Behind the 
eastern jetty, ships may at present find 
shelter against the rough easterly winds, 
if the tide or other causes hinder the 
approach to Dublin. The depth at the 
extremity of this jetty is 28 feet at 
low water, and 38 at high tides. The 
materials of the jetty consist of rocks 
and huge blocks of stone in two lines 
from SW. to NE. Dunfeary lies in 
the bay, about four miles and a half 
from Dublin.—It appears from a pub¬ 
lic notice, that beacon towers are erect¬ 
ing on Brownstown and Great Newtown 
Capes, in the county of Waterford, to 
point out the situation of the bay of 
Tramore. The intention is to warn 
mariners to keep at a certain distance, 
as a strong dangerous current frequently 
sets into the bay. 
FRANCE. 
The French clergy consists of three 
cardinals, with appointments valued at 
90,000 francs; 9 archbishops and 41 
bishops, 912,198 ; Royal Chapter of St. 
Denis, 200,000; 109 vicars general and 
416 canons, 867,500 ; 2885 parish priests, 
2,940,000; 26,152 inferior officiating 
ministers 15,500,000; about 4000 vicars 
with 3500 linages , i. e. where mass is 
said twice a day, 1,840,000 ; 1216 Dioce¬ 
san Bourses (a sort of fellowship) and 
2218 demi-bourses, 940,400; 183 pas¬ 
tors of Calvinists, and 174 do. of Luthe¬ 
rans, 485,000. Of these 18 bourses 
and 36 half bourses. 
A public notice is given in the French 
Maritime Journal, in case of ships 
being wrecked on the coasts of Barbary, 
or Fez and Morocco, that no resis¬ 
tance be made to the Arabs, which 
would be useless and very dangerous, 
but that an account of their situation 
be expedited to the French agent at Mo- 
gadore, accompanied with a promise of 
twenty piasters payable by the agent to 
whom the letter is addressed. The ship¬ 
wrecked persons are counselled not to 
separate, as it would be almost impos¬ 
sible to reassemble them if dispersed in 
the desarts. 
A prize being offered for the dis¬ 
covery of an horizontal direction in 
aerostation, M. Mingreli, of Bologna, 
M. Pietripoli, of Venice, and M. Lem- 
berger, of Nuremberg, have each as¬ 
sumed the merit of resolving this pro¬ 
blem. It does not appear, that any 
one of these has come forward, to 
establish by practical experiment, the 
validity of his claim, but a pamphlet has 
been lately reprinted at Paris (first 
printed at Vienne) on this subject, ad¬ 
dressed to all the learned societies of 
Europe. The following passage ap¬ 
pears in the work : 44 Professor Ro¬ 
bertson proposes to construct an aerosta¬ 
tic machine, 150 feet in diameter, to be 
capable of raising 72,954 kilograms, 
equivalent to 149,037 pounds weight 
(French). To be capable of conveying 
all necessaries for the support and safety 
of 60 individuals, scientific characters, 
to be selected by the academicians and 
the aerial navigation, to last for some 
months, exploring different heights and 
climates, &c. in all seasons. If from 
accident or wear, the machine elevated 
above the ocean, should fail in its func¬ 
tions, to be furnished with a ship that 
will insure the return of the aeronauts.” 
ITALY. 
Some further interesting discoveries 
of lost works have been made by M. 
Maio, among which are several parts 
of the mutilated and lost books of Poly¬ 
bius, of Diodorus, of Dion Cassius, 
some fragments of Aristotle, of Epho- 
rus, of Timeus, of Hyperides, of De¬ 
metrius of Phalaris, &c. some parts of 
the unknown writings of Eunapius, of 
Menander of Byzantium, of Priscus, 
and of Peter the Protector. Among 
the unedited works of Polybius are pro¬ 
logues of the lost books, and the entire 
conclusion of the 39th, in which the 
author takes a review of his history, 
and devotes his 40th book to chrono¬ 
logy. The fragments of Diodorus and 
of Dion are numerous and most pre¬ 
cious. Among them is a rapid reci¬ 
tal of many of the wars of Rome; a 
narrative of the civil, Punic, Social or 
Italic, and Macedonian wars ; those of 
Epirus, Syria, Gaul, Spain, Portugal,
