The average age of the 33 who died of lung diseases was 28. It is not doubted by medical witnesses that in this class of cases, as in the case of the tailors, one-third at least of the healthful duration of adult life will be found to have been destroyed by the ignorance of the want of ventilation. Unhappily, this fatal ignorance as to the requisites of the places of work is as frequently manifested in the overcrowded places of repose. I take an illustration from the answers of _Mr. Isaac Gilchrist_, surgeon of Aberdeen, to the question as to the causes of fever:— “In answering this query, the circumstance that calls for most remark in reference to this district is the overcrowded state of dwelling apartments. Six, eight, and even ten occupying one room is anything but uncommon; and these, too, it frequently happens, are lone women, all employed at the manufactories during the day and huddled together during the night. Fever finding its way into any of these apartments, seldom quits it until every member has been attacked. In some instances of families of eight or ten members, not one individual has escaped the disease. I believe also that deficient cleanliness (to a certain extent the result of poverty) and bad ventilation co-operate with the overcrowded state of the apartments in propagating fever.”
