the factors of external environment there are few which play so
important a role in the life of man as his habitation. Housing
conditions are powerful factors in the preservation of human life
and the prevention of disease. It has been statistically proven
that the death and disease rate of populations are greater in
cities than in the country. The density of population according to
area and congestion in localities and overcrowding in houses bear a
direct influence upon death and disease rates. Dr. Farr has shown
that death rates increased from 14 per 1000 when there were only 86
persons per square mile to 26 per 1000 when there were 3399 persons

rate in one-room apartments per 1000 was 21.4, in two rooms 18.8,
in three rooms 17.2, and in four rooms 12.3, showing a gradual
decrease in death rate with the decrease of overcrowding. There is
also an intimate relation between tuberculosis mortality and
morbidity and housing conditions. LIGHT AND ILLUMINATION. Natural
Light.--Sunlight is essential to the growth of animal and vegetable
life; it acts beneficially upon LIGHT AND ILLUMINATION 25 health,
stimulates the metabolism of the body and assists in the
oxygenation of the blood. Sunlight is also a powerful germicide and
disinfectant; it kills low organisms, fungi, and moulds, is capable
of destroying tubercle bacilli within a short time, and is
therefore indispensible in human habitations. Habitations without
direct sunlight are damp, cold, and unhealthy. The amount of
natural light within a house depends on: 1. The location and aspect
of the house. 2. The sources of light. 3. The location and size of
the openings through which it penetrates. 4. Th...
