[London,] 14 February 1885 

Dear Kautsky, 

I forgot to remind you day before yesterday that we are, as usual, 
expecting you and your wife to a meal this Sunday (tomorrow the 
15th inst.), i.e. if you have nothing better to do, and you are hereby 
given a standing invitation to take potluck with me on Sundays. 

Your 
F. Engels
