To the Editor:—
In commenting on the Russian stamp of 1956 honoring Benjamin Franklin (J. A. M. A.166:1081 [March 1] 1958), Prof. Nathaniel Kleitman calls attention to the two stamps issued by Russia in 1949 honoring I. P. Pavlov (1849-1936), the great Russian physiologist. Russia has also honored other physiologists—in 1956 with a three-color 40-kopek commemorative for I. M. Sechenov (1829-1905), "Founder of Russian Physiology," and in 1957 with a brown commemorative for William Harvey (1578-1657), on the tercentennial of his death. The latter shows Harvey in the Royal College of Physicians portrait, reversed.
