Blessing of the Ashes at a Tridentine Mass

Yesterday, Pertinacious Papist had a web-log post on the sermon given during the Ash Wednesday at his parish. I wish to quote the English translations that PP mentioned in the post:

Let us pray. -- O almighty and everlasting God, spare those who are penitent, be merciful to those who implore Thee; and vouchsafe to send Thy holy Angel from heaven, to bless + and hal+low these ashes, that they may be a wholesome remedy to all who humbly implore Thy holy Name, and who accuse themselves, conscious of their sins, deploring their crimes before Thy divine mercy, or humbly and earnestly beseeching Thy sovereign goodness: and grant through the invocation of Thy most holy Name that whosoever shall be sprinkled with them for the remission of their sins may receive both health of body and safety of soul. Through Christ our Lord.
R.: Amen.

Let us pray. -- O God, who desirest not the death, but the repentance of sinners, look down most graciously upon the frailty of human nature; and in Thy goodness vouchsafe to bless + these ashes which we purpose to put opon our heads in token of our lowliness and to obtain forgiveness: so that we who know that we are but ashes, and for the demerits of our wickedness are to return to dust, may deserve to obtain of Thy mercy, the pardon of all our sins, and the rewards promised to the penitent. Through Christ our Lord.
R.: Amen.

Let us pray. -- O God, who art moved by humiliation, and appeased by satisfaction: incline the ear of Thy goodness to our prayers and mercifully pour forth upon the heads of Thy servants sprinkled with these ashes the grace of Thy blessing: that Thou mayest both fill them with the spirit of compunction, and effectually grant what they have justly prayed for: and ordain that what Thou hast granted may be permanently established and remain unchanged. Through Christ our Lord.
R.: Amen.

Let us pray. -- O almighty and everlasting God, who didst vouchsafe Thy healing pardon to the Ninivites doing penance in sackcloth and ashes, mercifully grant that we may so imitate them in our outward attitude as to follow them in obtaining forgiveness. Through Christ our Lord .
R.: Amen.

Please take a look at some of the comentary that PP provides with these prayers: "Lent and the judgment of God"
