Opuscula varii argumenti
Various short works on reason
E80 is one of an unusual group of Eneström numbers. It refers to a collection of articles which were published together (in this case E86-E91), but were written on different topics. Usually referred to as Opuscula Varii Argumenti, Volume 1, this work is part of a three-volume series, the other two parts being E121 (Volume 2) and E156 (Volume 3).
