Karl Marx
The Poverty of Philosophy
For the second edition I have only to remark that the name wrongly written Hopkins in the French text (on page 45) has been replaced by the correct name Hodgskin and that in the same place the date of the work of William Thompson has been corrected to 1824. It is to be hoped that this will appease the bibiliographical conscience of Professor Anton Menger.
