HEP 
Hephthemimeris, or Hepht hammer es, is alfo a caefura 
after the third foot; that is, on the feventh half-foot. 
It is a rule, that this fyllable, thougli it be fliort in it-- 
felf, mud be made long oh account of the ctefura, or to 
make it a hephthemimeris. As in that verfe of Virgil: 
Et furiis agitatus amor , et oonfcia virtus. 
It may be added, tiiat the casfura is not to be on the 
fifth foot^ as it is in the verfe which Dr. Harris gives us 
for ah example: 
llle latus niveum mollifultus Hyacintho. 
This is not a hephthemimeris' caefura, but a liennea- 
mimeris, i. e. of nine half feet.

HEP SEY, a river of Wales, which runs into the 
Neath in'the-county of Brecknock. Mr. Malken, in 
his Scenery of South Wales, gives the following piCIu- 
refqite defeription of the views in this quarter. “ The 
route from Tragath to the falls of the Hepfey is over a 
wild common, dony and dreary, but that the dells on 
each fide enliven the feene. At the upper end of the 
common, there is a farm-houfe above the Hepfey, 
■whence t lie view down the vale of Neath to Svvanfcaand 
the Mumbles is very grand as well as extenfive. Be¬ 
yond the farm-houfe is the point where the Hepfey and 
Melta join. The bed of the former is at an imriienfe 
depth immediately below, and the two dreams are fepa- 
rated by a rich, turfy, well-wooded promontory, forming . 
a frontifpiece to the view, when you look up the courfe 
of the united rivers. The roaring of the Hepfey cafcades 
is heard at a confiderable didance, as they are ap¬ 
proached from the upper grounds. On arriving at the 
edge of the dingle, the great fall burfts at once Upon 
the view : a broad fheet of water projecting ilfelf over 
an abrupt ledge of rock, to the depth of fifty feet. The 
didance of the fall from the junction of the two dingles 
with their dreams is lefs than a quarter of a mile, fo 
that both thefe objeCts can be embraced at once from 
the higher ground. But the general view of feenes like 
thefe is never the mod intereding. The lefs obtrufive, 
blit mod beautiful, features are lod, while the termi¬ 
nation detracts from the fublimity. By taking the parts 
in detail on the contrary, the attention, undidurbed, is 
alive to every concomitant circumftance, as well as to 
the leading character of the objeCt : nothing is over¬ 
looked, becaufe nothing is too diftant, or too perplexed, 
to be taken in both by the mind and by the eye: every 
turn prefents fomething new; while the perfpeCtive, 
ledened into obfeurity as it lengthens, holds out the 
promife of dill unexhauded variety. The defeeut by 
which to examine the fall more minutely, is down a 
rugged and deep rock, which forms the bolded feature 
in the dingle at the bottom, but affords a very abrupt 
and hazardous paflage. The.afcent on returning, were 
it necedary, would be very difficult; and there is appa¬ 
rently no other way; for the violence with which To 
large a body of water is precipitated, has worn the rock, 
of the bed below the cafcade into a large and deep pool, 
and the breadth of the water all through the dingle, 
efpecially when augmented by heavy rains in the night, 
as’ on the prefent occafion, befides other obdacles not 
yet appearing, prevents its being forded. It excites 
HEP 399 
therefore a drong fenfation of furprife, not unaccompa¬ 
nied with pleafure, in the mind of a dranger, when he 
is told, that his road lies, very unexpectedly, behind 
or under the cafcade; for fuch' is the rapidity of die 
torrent, unprepared by previous obdacles for the per¬ 
pendicular of the precipice, that the interwoven meet 
is thrown out fo far, as to leave a clear p.affkge;' at all 
times, wide enough for a horfe-path, between the falling 
river and the rock. This patli is formed by a rude 
natural'ledge'of limedone, covered with mofs, at about 
one third of the height from the bottom of the precipice. 
Its breadth is about three feet, and con dilute s the only 
pr'oje&ion in what would otherwife be like a fiat wall. 
The done, however, fhelves a little inwards from the 
topntod edge, while the water is forced forwards; fo. 
that the two elements unite in forming as it were a roof 
or canopy over the head of the paitenger, which affords 
him an impenetrable (belter from an oceafionM dorm. 
Mr. Warner, when he, 'vidted this fpot, had occafion to 
feek the protection of the river from a fhowei of rain. 
The eft'eCt of fundiine on the cafcade, when behind U 
on a fine day, is both grand and beautiful. The parti¬ 
cles of water glittering with a filvery brightnefs as they 
fall ; the uncommon brilliancy of every thing without, 
feen through fuch a medium, contraded with the dark 
green, o'f the mofs, everladingly wet with fpray; the 
corroded dinginefs of the rock ; the damp and vaporous 
gloom of the attnofphere within; altogether form a 
fingularly mingled feene of awe and gaiety. The dark, 
hue of the bafon below, deeply excavated by continual 
attrition, enhances the contraft of the thin tranfparent 
fluid in its defeent. After paffmg the cafcade, the 
dranger has to (kirt the further fide of the dingle for a 
few deps, in'front of the majedic rock he defceiufed; 
when he comes upon another cataraCt, and a large cavern 
undqr the oppofite bank clofe by. Three more follow 
in immediate fucceflion, and all four within an eighth 
part of a mile from the fird. The mod confiderable of 
thefe is about twenty-five feet in height;- and the fmall- 
ed about ten. The lad is the larged. Thefe four are 
all feen at once : but, owing to a bend of the river, the 
great cafcade, though fo near, is not feen even from the 
fird of thefe. Were the five vifible at one point of view, 
they would nearly rival the great fall of the Mynach in 
Cardiganfhire, below the Devil’s Bridge; for though 
they would dill be very inferior in point of height, the 
Hepfey is much broader than the Mynach, and in that 
refpeCt would have the advantage in refped to.grandeur. 
The whole of this dingle is profufely overgrown with 
wood of various kinds, among which the venerable and 
claffic oak predominates. From tlie lad of the cafcades 
the fcarcely-difcernible path winds round the front of 
that promontory, which feparates the two dingles and 
their rivers. But there is a path; for the country 
people drive their cattle this way, and under Hepfey 
cafcade, when they have occafion to pafsTrom the 
Melta to the eadern fide of the Hepfey.”
