These figures from widely-different sources testify to the fact that the greatest number of cases of hæmoptysis occurs between twenty and thirty years of age, or at least with a variation of only about a year from those extremes. The possibility of hæmoptysis, if we may judge by cases reported, lies anywhere between sixteen days of age and the limit of life. A case of hæmoptysis in a child sixteen days old is alluded to in Nouv. Dict. de Méd. et de Chirurg.29 The oldest on the list of the Vienna Hospital reports is seventy-two. In our Cincinnati Hospital list we have 7 over seventy years. Others have reported cases beyond these figures.
