“…Bacteria have also been separated by a comparison of their charges by Falk and his school (Falk, 1928). The differentiation of Haemophilus pertussis strains has been done by Shibley (1932) using these methods. Of the four types of pneumococci causing lobar pneumonia, both the potential difference (P. D.…”

“…while Reed and Gardiner (1932) have compared complete mobility curves for both Rand S types of Mycobacterium leprae. The differentiation of Haemophilus pertussis strains has been done by Shibley (1932) using these methods. Erythrocytes have also been shown by Abramson (1929) to possess a specific P.D.…”
