They are glad to enter in the guise of galley-slaves with irons on their ankles; since, when they have got in, they will find no difficulty in loosing their own bonds and binding others' (_ibid._ p.

134).

'They command two arts: the one of escaping from the bonds and obligations of any vow or promise they shall have made, by means of equivocation, tacit reservation, and mental restriction; the other of insinuating, like the hedgehog, into the narrowest recesses, being well aware that when they unfold their piercing bristles, they will obtain the full possession of the dwelling and exclude its master' _( ibid_.p.

144).
