besides _-mu-_ is _gu-_, _gw-_, _u-_, _wu-_, _yu-_,
_n-_, &c.

The second prefix. _Ba-_ or _Aba-_, is, in the most archaic Bantu speech
(the languages of Mt. Elgon), _Baba-_ in its definite form (_Ngaba_
sometimes in Zulu-Kaffir). The concord is _-ba-_ in all the less corrupt
Bantu tongues, but this plural prefix degenerates into _Va-_, _Wa-_, _Ma-_,
and _A-_. The concord of the 4th prefix, _Mi-_, is _gi-_, _-i-_, _-ji-_,
and sometimes _-mi-_. The commonest form of the 5th prefix at the present
day is _Li-_ (the older and more correct is _Di-_), and its concord is the
same; this 5th prefix is often dropped (the concord remaining) or becomes
_Ri-_, _I-_, _Ji-_, and _Ni-_. The 7th prefix, _Ki-_, in many non-related
dialects pursues a parallel course through _Ci-_ into _Si-_ (=_Shi_) and
_Si-_ and its concord resembles it. The 8th prefix is still more variable.
In its oldest form this is _Ibi-_ or _Mbibi-_. It is invariably the plural
of the 7th. It becomes in different forms of Bantu speech _Vi-_, _Pi-_,
_Fi-_, _Fy-_, _P[vs]i-_, _[vS]i-_, _I-_, _By-_, _Bzi-_, _Psi-_, _Zwi-_,
_Zi-_ and _Ri-_, with a concord that is similar. The 10th prefix, which was
originally _Ti-_ or _Tin-_, or _Zi-_ or _Zin-_, becomes _Jin-_, _Rin-_,
_Din-_, _Lin-_, [theta]_in-_, [theta]_on-_. &c. The _n_ in this prefix is
really the singular prefix No. 9, which is sometimes retained in the
plural, and sometimes omitted. In the case of the 10th prefix, the concord
or corresponding pronoun persists long after the prefix has fallen out of
use as a definite article. Thus, though it is absent as a plural prefix for
nouns in the _Swahili_ of Zanzibar, it reappears in the concord. For
instance:--_Nombe hizi zangu_--Cows these mine (These cows are mine),
although _Nombe_ has ceased to be _zinombe_ in the plural, the _Zi-_
particle reappears in _hizi_ and _zangu_. In fact, the persistence of this
concord, which exists in almost every known Bantu language in connexion
with the 10th prefix, shows that prefix to have been in universal use at
one time. The 11th prefix _-Lu-_ seems to be descended from an older form,
_Ndu-_. Its commonest type is _Lu-_, but it sometimes loses the _L_ and
becomes _U-_, and in the more archaic dialects is usually pronounced _Du-_
or _Ru-_. It is also _Nu-_ in one or two languages. The 12th prefix
(_Tu-_), always used in a diminutive sense, disappears in many of these
languages. Where met with it is generally _Tu-_ or _To-_, but sometim
