He entered each room, examined its means of ventilation and its contents, noted the number of occupants by day and by night, and carefully estimated the cubical area to each person. Whenever any contagious or infectious disease was discovered, as fever, smallpox, measles, scarlatina, the Inspector made a special report upon the dwelling. This report embodied specific answers to a series of questions, furnished in a blank form, requiring him 1. To trace and record the medical history of the sick person. 2. To ascertain and record facts relating to the family and other persons exposed to the patients and to the causes of the malady. 3. To report the sanitary condition of the domicil. 4. To report the statistics and sanitary condition of the population of that domicil. 5. To report upon the sanitary condition of the locality or neighborhood and its population. 6. To preserve and make returns of these records. 7. To prepare on the spot the necessary outlines or data for the sketching of a map or descriptive chart of the domicil, block, or locality.
Each Inspector was supplied with a notebook and a permanent record-book; in the first he constantly made notes as his examination proceeded, and in the latter these notes were expanded and put on permanent record. These permanent record-books are the property of the Association and embrace for the most part minute details concerning every building and tenement occupied by the laboring classes, as also, grog-shops, stables, vacant lots, slaughter-houses, etc.
Each Inspector was furnished with materials for drawing, and was directed to make accurate drawings of the squares in his district, locating each building, vacant lot, etc., and distinguishing the character and condition of each by an appropriate color. Many of these drafts of districts are beautiful specimens of art, and as sanitary charts enable the observer to locate infectious and contagious diseases, and with the aid of the permanent records, to determine the internal and external domiciliary conditions under which they occur.
I have been thus minute in specifying the details of the plan of inspection, the qualifications of the Inspectors, and the means employed, in order that the character of the work and the value of the results obtained may be properly appreciated.
