With regard to the third question, we beg to say that the ciborium or particles ought to be placed on the altar-stone, and that not only during the consecration, but to the communion. The chalice and host must be placed on it, according to the rubric; of the missal, and we see no reason why the same thing is not to be done with the small particles which are to be consecrated. St. Alphonsus Liguori is clearly of this opinion: "Non igitur licet ante communionem ponere particulas consecratas extra aram". La Croix, treating of the same subject, says: "Post communionem sacerdotis possunt parvae hostiae ab eo consecratae poni extra aram in corporali"; and he gives the following reason: "Quia omnes sunt unica victima et per modem unius offeruntur". Indeed La Croix, for the same reason, states that it would be unlawful to have a second altar-stone, in case the one would not be large enough to hold the small particles together with the chalice and host: "Si unum portatile non possit cum hostia et calice capere omnes particulas consecrandas, illicitum esset has collocare et consecrare in alio portatili vicino". The best, and indeed the only remedy we can suggest, especially where there are many communicants, is to procure a large altar-stone. We have heard of some bishops declining to consecrate any stone that was under fourteen inches in length, and twelve inches in width, at least. It is unnecessary to observe that there is great danger, and irreverence too, in placing a large number of particles on a very small space or corner of an altar-stone, where an accident, and that of the most serious nature, is likely to take place at any moment. Perhaps it may not be amiss to remark, also, that those theologians who hold the opinion that the rubrics are merely _directivae_, except always such rubrics as are closely connected with the Most Blessed Sacrament, and maintain that those are _praeceptivae_. We conclude, therefore, that the ciborium or particles ought to be placed on the altar-stone, and if the altar-stone be too small for the chalice and host, it ought not to be used. II. 1º. At High Mass, ought the celebrant to elevate the Host before the choir has terminated the singing of the Sanctus and following words? _Answer_: The _Caeremoniale Episcop._ lib. ii. no. 70, gives the answer: "Chorus prosequitur cantum usque ad _Benedictus qui venit_ exclusive: quo _finito et non prius_ elevatur sacramentum. Tunc silet chorus et cum aliis adorat. Organum vero, si habetur, cum omni tunc melodia et gravitate pulsandum est". The celebrant ought to proceed slowly with the canon, so as to give time to the choir to terminate their part before he comes to the elevation. The choir ought to be cautioned not to protract the singing of the Sanctus too much. 2º. At High Mass, when the celebrant has sung "Et ne nos inducas in tentationem", in the Pater Noster, is he bound to wait until the choir has finished singing "Sed libera nos a malo", before he says Amen?
