 Upon arriving in Venice, Frederick again caught cold; privately, Mackenzie was growing seriously concerned, having observed a continued tendency for Frederick's throat and larynx to swell.He forbade Frederick from speaking at any length, noting that if the Crown Prince insisted on speaking and contracted further colds, he could give him no more than three months to live.At the beginning of October, Victoria noted that "Fritz's throat is giving no cause for fresh anxiety & he really does take a little more care and speaks a little less."
