March 21, 1909
As you probably know from the newspapers there is a post office strike going on here. Complete irregularity. I am not getting the proofs (I have received nothing since the page proofs of signature 13).
In any case I am sending this by registered post and ask you to send a registered reply too.
(1) I am sending a list of misprints in signatures 1–5.
(2) I am sending a correction to p. 630 of the MS.
(3) Please include this in the errata; footnote at the beginning of Section 6 of Chapter Three (i.e., the section on freedom and necessity)—instead of “not only a smile” read “not a smile, but disgust”.
This is an essential correction and if it is not made my idea will be distorted; I do not see anything funny in flirting with religion, but I see a lot that is disgusting.
I have already written about not, under any circumstances, toning down the passages against Bogdanov and Lunacharsky in the second half of the book and hope you have received the letters. Especially—do not throw out “Purishkevich” and the others in the section on the criticism of Kantianism!
I have received a postcard from Mark. How is Mother’s convalescence progressing? Give her many kisses for me. We are all well and send regards.
March 22, 1909—today there is news of the end of the post office strike. Nevertheless I am sending this by registered post and ask you to answer also by registered post—just in case!
 This correction has been lost.—Ed.
 There follows, in the original, a list of the misprints.—Ed.
 The strike of French post and telegraph workers lasted from March 15 to March 23, 1909.
