HENLEY upon Tuames, a town of England, in the 
county of Oxford, is situated on the left bank of the 
river Thames, which is crossed by a fine bridge of five 
.arches, with a handsome ballustrade instead of a para- 
t. The keystones in the centre arch contain two 
Feeds of the Thames and Isis, which were sculptured 
by the Honourable Mrs Damer. The town consists 
of two principal streets, at right angles to each other, 
and some smaller ones. The street which extends 
from the bridge to the cross is not very long, but is 
spacious, and contains some good houses. The street 
which extends from the cross along the Oxford Road 
has a serpentine direction. ‘It is longer than the other, 
and contains many excellent houses. At the junction 
-of these streets is a simple stone ‘obelisk, pointing out 
the direction of the roads, and the distances from Lon- 
don. The church, which is a very ugly building, is 
situated near the bridge, on the west side of the street. 
It has a'‘tower with semi-octagonal buttresses at each 
angle, and embattled at the top. It is built of -flints 
and stones. The tower is said to have been built at 
the expence of Cardinal Wolsey. ‘The other esta- 
-blishments in Henley are a Royal Grammar School, 
founded by King James V. for educating 25 boys in 
the classics; a blue coat school, founded by Dame 
Elizabeth Perians, for educating and clothing 20 poor 
boys; a green coat school, and an alms house. Hen- 
ley carries.on a considerable trade with London b 
means of the Thames, in malt, flour, and beechwood. 
oe 80,000 quarters of flour are annually made

HERALD. In the histories of the heroic ages, we 
find important functions ascribed to those officers whom 
the Greeks call xagvxec, and the Romans feciales. Their 
character is represented as sacred and inviolable ; and, 
in Homer, their common epithet is “ the divine”? Their 
ny 
‘ duties were not less numerous than important. They 
eens enter without difficulty into cities that were be- 
sieged, and mingle without danger among contending 
armies, They summoned the ‘chiefs rng. council ; 
they commanded silence, that the discourses of the — 
kings might be heard ; and presented to each of them 
the sceptre before he commenced his harangue. The 
herald was charged with the most delicate missions, 
and accompanied his prince on the most difficult occa 
sions. Agamemnon sent only Talthybius and Euryba- 
tes to’ bring Briseis from the tent of Achilles ; and when 
Priam went to: the body of his son, he took no one 
with him but his d. The herald was distingui 
ed by a long rod or sceptre, which he carried in his 
hand ; and from this circumstance it was, that the Ro- 
mans gave him the name of caduceator. Eckhel has 
pabhviael a beautiful medal of Crotona, from which we 
may judge of the dress of a xagvg, at a time much later 
than the age of Homer. He is arrayed in a long tunic 
like that of a priest, and holds in his hands a patera 
and a caduceus. The patera denotes a libation or offer- 
ing to the gods, a function with which the heralds were 
frequently a According to Eckhel, this herald 
isin the act of demanding peace, and the coin was 
most probably struck at the tirhe when the people of 
Crotona, humbled ‘by a severe defeat, were obliged to 
send envoys to beg of the Locrians. The atti« 
tude of stretching out the right hand seems to have 
been considered as consecrated to the use of heralds; 
and it is on this account, that, on the imperial medals, 
the emperor is commonly represented in the same po- 
sition when’ he announces peace and security to his 
eople. ; ; R: ; 
The cuse of heralds was very long preserved among 
the Greeks. There were heralds whose office it was to 
proclaim the laws-observed at the olympic games, the 
names of the combatants and the victors, and, in ge~ 
neral,-every thing which was commanded-by the judges 
of the games. The best account of the xngvg of the | 
Greeks, and the Frcrauis of the Romans, is to be found 
in the works of Grevius and Pitiscus; or, if ancient 
authors be preferred, in Homer throughout ; pag i, 
32; Cicero De Legibus, ii. 9; and Dionysius - 
carnass. lib. 2. iv Lit 
In the middle ages also, the heralds perform a part 
of considerable importance. The origin of their name
