To the Editor:  —I was rather surprised that The Journal should publish such an unfair criticism of a book as it did of "The Place of Version in Obstetrics" by Dr. Irving W. Potter (The Journal, July 1, 1922, p. 64).First, the critic's bias was so great and his erudition so incomplete that he lost sight of the real aims of the book, namely, a more extended use of version and an improved technic. He assumes, with the assurance and omniscience of a deity, that Potter is left handed and that that is why he uses the left hand in delivery; while, as a matter of fact, he is right handed in all his work, but has found that the left hand is the best hand with which to make all deliveries when version is employed.The illustrations (Figs. 36, 38 and 39) "show awkwardness" only to the inexperienced
