33. If before the Consecration the priest becomes seriously ill, or faints, or dies, the Mass is discontinued. If this happens after the consecration of the Body only and before the consecration of the Blood, or after both have been consecrated, the Mass is to be completed by another priest from the place where the first priest stopped, and in case of necessity even by a priest who is not fasting. If the first priest has not died but has become ill and is still able to receive Communion, and there is no other consecrated host at hand, the priest who is completing the Mass should divide the host, give one part to the sick priest and consume the other part himself. If the priest has died after half-saying the formula for the consecration of the Body, then there is no Consecration and no need for another priest to complete the Mass. If, on the other hand, the priest has died after half- saying the formula for the consecration of the Blood, then another priest is to complete the Mass, repeating the whole formula over the same chalice from the words Simili modo, postquam cenatum est; or he may say the whole formula over another chalice which has been prepared, and consume the first priest's host and the Blood consecrated by himself, and then the chalice which was left half-consecrated.

41. If the Blood freezes in the chalice in winter time, the chalice should be wrapped in cloths that have been warmed. If this is not enough, it should be placed in boiling water near the altar until the Blood melts, but care should be taken that none of the water gets into the chalice.
