A quick post on two sections of IO:
VII. SACRAMENTALS (SC 79)
76. For the blessing of candles on 2 February and of ashes on Ash Wednesday just one of the prayers for these in the Missale Romanum suffices.
77. The blessings in the Rituale Romanum tit. IX, cap. 9, 10, 11, hitherto reserved, may be given by any priest, except for: the blessing of a bell for the use of a blessed church or oratory (cap. 9, no. 11); the blessing of the cornerstone of a church (cap. 9, no. 16); the blessing of a new church or public oratory (cap. 9, no. 17); the blessing of an antemensium (cap. 9, no. 21); the blessing of a new cemetery (cap. 9, no. 22); papal blessings (cap. 10, nos. 1-3); the blessing and erection of the stations of the cross (cap. 11, no. 1), reserved to the bishop.
Not much of earth-shaking liturgical import, but there you have it.
