To the Editor:
—Your comments on "Physicians' Exemptions for Income Tax" (The Journal, Feb. 22, 1919, p. 576) were very instructive—in my own case, a great deal more so than you could have imagined when you published the editorial.What did it teach me?

On seeing the actual figures, I found that it ran about $5,300 total collections.
