Now in order to make out what the higher
multitudes are, it will be necessary for me
to prove to you a proposition which I was the
first to enounce and to prove. The proposition
is this.

Take any gath whatever, whether
it be enumerable or innumerable, and call
its units the Ms. Now I am going to describe a sam
which I call the exponential of the Ms.
Every member of this sam called the exponential of the Ms is
itself a a sam composed exclusively of Ms
and this exponential sam comprises
among its members every sam that is composed
exclusively of Ms.

For example suppose the Ms
are only four, say M1, M2 , M3, M4.
