I am sending you a terribly important insertion to the pamphlet. Please see that it goes in without mistakes. If the pamphlet can be put out by Tuesday or Wednesday, send 10–20 copies to Shklovsky by express post.
 This refers to the beginning of Chapter II of the pamphlet Socialism and War headed “Classes and Parties in Russia”.—Ed.
