[London,] 12 November 1880 

In HASTE 

Dear Friend, 

Herewith a card of introduction to my son-in-law Longuet who is 
to introduce you to Rochefort. 

No doubt you will by now have received the letter my wife even- 
tually sent off; like all female invalids, she always despairs of the doc- 
tors who happen to be attending her. 

With kindest regards, 

Yours very sincerely, 
Karl Marx
