alized _cild_, &c. became _child_, &c. In
Provencal from the 10th century, and in the northern dialects of France
from the 13th century, this palatalized _c_ (in different districts _ts_
and _tsh_) became a simple _s_. English also adopted the value of _s_ for
_c_ in the 13th century before _e_, _i_ and _y_. In some foreign words like
_cicala_ the _ch-_ (_tsh_) value is given to c. In the transliteration of
foreign languages also it receives different values, having that of _tsh_
in the transliteration of Sanskrit and of _ts_ in various Slavonic
dialects.

As a numeral C denotes 100. This use is borrowed from Latin, in which the
symbol was originally [Illustration] This, like the numeral symbols later
identified with L and M, was thus utilized since it was not required as a
letter, there being no sound in Latin corresponding to the Greek [theta].
Popular etymology identified the symbol with the initial letter of
_centum_, "hundred."

CAB (shortened about 1825 from the Fr. _cabriolet_, derived from
_cabriole_, implying a bounding motion), a form of horsed vehicle for
passengers either with two ("hansom") or four wheels ("four-wheeler" or
"growler"), introduced into London as the _cabriolet de place_, from Paris
in 1820 (see CARRIAGE). Other vehicles plying for hire and driven by
mechanical means are included in the definition of the word "cab" in the
London Cab and Stage Carriage Act 1007. The term "cab" is also applied to
the driver's or stoker's shelter on a locomotive-engine.

Cabs, or hackney carriages, as they are called in English acts of
parliament, are regulated in the United Kingdom by a variety of statutes.
In London the principal acts are the Hackney Carriage Acts of 1831-1853,
the Metropolitan Public Carriages Act 1869, the London Cab Act 1896 and the
London Cab and Stage Carriage Act 1907. In other large British towns cabs
are usually regulated by private acts which incorporate the Town Police
Clauses Act 1847, an act which contains provisions more or less similar to
the London acts. The act of 1869 defined a hackney carriage as any carriage
for the conveyance of passengers which plies for hire within the
metropolitan police district and is not a stage coach, _i.e._ a conveyance
in which the passengers are charged separate and distinct fares for their
seats. Every cab must be licensed by a licence renewable every year by the
home secretary, the licence being issued by the commissioner of police.
