What reading level is The Sanitary Value of Wall Paints book?
To quickly assess the difficulty of the text, read a short excerpt:
Samples of wall paper, which had been applied to plastered walls for a year or more, were obtained, and examination uti- der the microscope showed a most uncleanly surface. Cultures were made of these sam- ples, and bacilli of different types were de- veloped in the culture medium in a short time.
Experimental Evidence: That the above conditions could not have existed, had proper wall paints been used, seemed doubt- less, and suggested a carefully conducted experiment to prove the relative sani...tary values of wall paper and wall paints. A large sheet of fibre board, such as is occa- sionally used to replace plastered walls, was painted on one side with a high- grade wall paint, three-coat work. A simi- lar sheet was papered on one side with a clean, new wall paper. These test panels were placed where unsanitary conditions, such as dampness, foul odors, and a scarcity of air were present. After a short period of exposure, the panels were taken to the bacteriological laboratory and a small sec- tion of the painted surface, about two inches square, as well as a small section of the papered surface of similar size, were removed and used for making cultures.
