SHAKESPEARE, Richard III.

My conscience is but a kind of hard conscience . . . The fiend

gives the more friendly counsel.

Merchant of Venice.

Thou hast it now - and I fear

Thou play’dst most foully for it.

Macbeth.

Canst thou not minister to a mind diseased,

Pluck from the memory a rooted sorrow,

Rase out the written troubles of the brain,
