phonetic principle,
like
the
magnetic
fluid,
acting
on
the
vowels,
produces
the
law of
vowel assimilation
;
and on
the
consonants,
is the
origin
of
aspirating
and
eclipsing.
Thus the
Welsh term
tref,
a
habitation,
(in
Irish
"
treib"
a
tribe,
a class
of
people)
is tlirev
"th" when
"a"
precedes
;
marw
(dead),
Irish
"
marB,"
becomes,
when
compounded
with
"di"
(want, defect)
di-varu,
immortal
("m"
into
"
v.")
So
in
Irish
"
marB,"
dead
;
"
di-marB,"
immortal
;
"
m"
is
aspirated by
the
influence of
"i,"
in
"di:"
and
"f
"
in
"
diBfeirge,"
wrath,
eclipsed.
The harmonic action
of
the vowel
sounds leads
to
aspiration
and
eclipsis.
This
view,
just
now
presented,
has
occurred
to the
writer
for the first time while
penning
this
page.
He
suggests
it
but
does
not
hold
it
as
an
opinion.
No
doubt,
like
colors,
or some notes in distinct
octaves,
the two laws
have
at least
a
remote and an
indirect
relationship.
Re-
garding
the
law
of
vowel
assimilation,
however,
his
opinions
are settled. He has devoted
attention to
it
from
time to
time,
since he was
eighteen years
old. He has
read all
the
views
of
all
those
who
have
written
on
the
subject.
Some writers
they
are
few have
declared
the
division
of the
vowels
into broad
and
slender,
is the
in
vention of
bards
or
rhymers.
This
was
the
opinion
of
Dr.
John
O'Brien,
Bishop
of
Cloyne
;
of Colonel
Vallancey,
of
Halliday,
of P.
MacEllegott
but
these writers
never
gave
the
subject
the
slightest
thought,
at least
they,
in
their
writings, give
no
reason
for their
strange
opinions.
The science
of
comparative
philology
had not
been
known when
they
lived.
Some
of them
were
very
inac-
curate
in
thought,
and
very illogical
in
reasoning.
Few
scholars
now-a-days
care
to notice Colonel
Vallancey,
and
poor
Halliday
died
when
only
a
young
man. Had
he
lived he would doubtless have
become
a
distinguished
Keltic
scholar.
