I'm looking for the paper

It is supposedly hosted at the Digital Repository of Scientific Institutes (RCIN) [here](http://rcin.org.pl/dlibra/docmetadata?id=24030), but I cannot access it, although I have registered in the site.


Can someone locate another online copy, or send one to me?



Locate the paper "Extensions of general algebras" by Eilenberg
I have finally been able to look at the paper via a university library.
