1. In lamdbda calculus one may obtain  the one place-relation from the 
two place relations as follows:
given LxLy[x>y]
new Lz[z>z] =  Lz[ LxLy[x>y](z)(z)]
2. Frege did not have lambda's, but he knew the standard mathematical 
method to reduce the number of arguments.
Let be given f defined by f(x,y) = x>y.
Then we may define g by g(x) = f(x,0) and h  by h(x)= f(x,x).

There is nothing wrong or problematic with Frege's remarks one finds in 
Carnap's lecture notes.
