DISCUSSION in FAVOUR of LIBERTY Of 
CONSCIENCE. By the REV. CHRISTOPUER 
WYVILL. 
T is evident that a favourable impres- 
sion has been made on the publi¢ 
inind, by the jate debates in parliament 
on the claims of the Lrish Catholics. 
To the old and well-known arguments 
for concession, drawn from the po. 
licy of conciliation, and from the increased 
liberality of the times, new force has 
been added by the weighty character, 
the probity, the wisdom and diberality 
of Mr, Ponsonby, and by the genius and 
eloquence and especially by the mode- 
rauion of Mr. Grattan, so signaliy dis- 
pluyed in the House of Commons; and 
not less powerfully, perhaps, were those 
arguments reinforced in the upper house 
of parliament, by the vigorous and con. 
prehensive reasoning of Lord Grenville, 
and by the nuld but dignified conduct ef 
the Bishop of Norwich, whose wisdom 
and truly Christian spirit of candour and 
penengence have done bonour to the mi- 
tre. Yet, from the terms of the petition 
then before the two houses, the advocates 
for concession, if not precluded virtually 
from touching on the right of al! men te

naturally led to be sparing of arguments 
drawn from that right, and to press their 
point chiefly, if not entirely, on princi 
ples of Jess extent, ‘Lhis was natural,
