FOOTNOTES:

[1] There have been found at Caerwent, in Monmouthshire, clear traces
of wooden pipes (internal diameter about 2 in.) which must have
carried drinking-water, and almost certainly a pressure supply from
the surrounding hills. Some patches of lead also have been found
obviously nailed on to the pipes at points where they had burst (see
_Archaeologia_, 1908).

[2] This distance will not agree with the length given on some of the
_cippi_ (Lanciani, _Bull. Com._, 1899, 38).

[3] The course of the Aqua Claudia was considerably shortened by the
cutting of a tunnel 3 m. long under the Monte Affliano in the time of
Domitian (T. Ashby, in _Papers of the British School at Rome_, iii,
133).

[4] About 3 m. south-east of this point the presence of large
quantities of deposit and a sudden fall in the level of the channels
seems to indicate the existence of settling tanks, of which no actual
traces can be seen.

Priscilla had settled in Corinth, where Paul stayed with them (Acts
xviii. 2,3). They became Christians and fellow-workers with Paul, to
whom they seem to have shown their devotion in some special way (Rom.
xvi. 3, 4). (2) A native of
