Of what is to be done, if the Sacrament, in either kind, hath been Consumed before all the People have Communicated
If proper care be exercised by the priest, both as to the quantity of bread and wine to be consecrated, and also in his administration of the sacrament, the contingency here referred to will not occur. When it does occur, the priest must consecrate both bread and wine, and communicate himself with both kinds (of that which he has just consecrated) ere he proceeds to continue the administration to the people.
If the hosts fail, and not the Precious Blood, he must needs use another chalice into which he will pour a little wine and a few drops of water. If the precious Blood fail, and not the hosts, he will drain the chalice (i. e. he himself drinking whatever may remain therein), and then pour into it such a quantity of wine as may be needed and a little water. Thus, be the case as it may, having before him unconsecrated bread and wine, and having mentally made an oblation of each, the priest will proceed to consecrate them, using the prayer beginning with the words "All glory be to thee, Almighty God," and ending with the words, "partakers of his most blessed Body and Blood." In efforts to avoid the necessity of a second consecration, hosts may be broken into small pieces, but never should there be any impairing of the contents of the chalice by pouring in unconsecrated wine.
