In Franee, undet the feeond

DUMllNE3S, the prieation of the fAC"lty of fpeech.
The moll general,

rlther the fole cauíe of dnmo·
nefs, is the lI'anl of the fenfe of hearing. Tbe ufe
of
langu.geis originally aequired by imitdling articu·

people are intirelyexcluded: they eannot aequire ani·
eulate founds byIhe ear : unlefs, therefore. artieulation

unhappy people mull for over be dcpri,'ed

laoguage; and as language is the principal fouree of
knowledge, whoever has Ihe misfonune 10 lVaut lhe
fenfe of hearing, mufl remain in a flate Iinle fuperior
to that of the brule creatioll. Deafnefs has in all
ages been confidered as fueh a total obfl ruélion 10
fpeeeh,
01'
writtrn language, that an anel11pt (Oteach
thedeaf tOfpeak or read has bten uniformly regarded
as impraélicable, till Dr Wallis and fome. others have
of late !hewn, thal although
d~.f
people cannollearn
toCpe.k
01'
read by the direélion of the ear, Ihere'are
other fourees ofimitation, by \Vhieh the fame eReél may
be produced. The organs of hearing and of fpeeeh
have linle
01'
no conneélion. Perfoos depril'ed
or
the
former gcnerally polTefs the lamr in fuch perfeélion,
that nOlhing fulthcr is necelTary, in order tO male
them articulate, than tOleach them how tO ufe

Olews Ihat it is praélicable. MI' l'HOM.\S BRA ID'
