  Our construction of the Wiener measure on $\textbf{C}=\textbf{C}[0, \infty)$
consists in first defining a set function $\varphi$\ on the class of all
compact sets based on certain $n$-dimensional normal distributions, $n = 1,\
2,\ldots$\ using the structural relation at (\ref{E1.2}) below. This structural
relation, discovered by the first author, is recorded in his book (2013) on
page 130. We then define a measure $\mu$ on the Borel $\sigma$-field of subsets
of $\textbf{C}$ which is the Wiener measure. This is done via a similar
construction of the Wiener measure on $\textbf{C}_a=\textbf{C}[0, a)$ where $a
> 0$ is an arbitrary real number.
  The traditional way is to first construct the Brownian Motion process (BMP)
and then, by proving it is a measurable mapping into $(\textbf{C},\
\mathscr{C}_\infty)$, call the measure induced by the BMP on $\textbf{C}$\ the
Wiener measure. In the present paper, we define the Wiener measure directly.
