[London,] 21 Jury [1871] 

Dear Oswald, 

I must once again pester you for a passport—one with a visa 
from the French Consulate. (The last one is already in Paris.) *** 
Through your efforts, you have already saved 6 people, and such 
a noble achievement is the best reward for your labours. 

Yours in sincere friendship, 

Karl Marx
