Abstract

IN the article to which Dr. Saffman refers1, it was stated that tests in 1958 using horizontal disks showed a decrease of about 40 per cent in the viscosity of air when dust was suspended in it at a concentration of about 0.25 kgm./m.3. Subsequent tests in 1960 using vertical cylinders yielded the same result, within experimental error.
