As Andreas Blass and others surmised, this is indeed an abstract. It was for a 10-minute talk at the Annual Meeting in January, 1975. Here is the entire "paper":

On Manifolds with nonnegative Ricci curvature II

Let $M$ be an $n$-dimensional Riemannian manifold with nonnegative Ricci curvature. Then the exponential mapping $\exp_p$ for any $p\in M$ , restricted to the domain bounded by the cut locus, is everywhere volume decreasing.From this fact one deduces the following THEOREM. Let $M$ be a Riemannian, $n$-dimensional, complete manifold with nonnegative Ricci curvature. Then, if $r$ denotes the injectivity radius and $D$ the geodesic diameter of $M$ , the volume $V$ of $M$ satisfies $V \ge c_n > r^{n-1}D$, where $c_n$ is a positive constant depending on $n$ . In particular, if $M$ is not compact (i. e. if $D=\infty$), the volume of $M$ , under the same assumptions, is infinite. (Received November 6, 1974.)

A couple of notes. I reproduced the capitalization and (non)hyphenation of the title as it appeared in the Notices. I also tried to preserve some oddities in punctuation in the text, but otherwise "TeX-ified" it; the original is literally typed, with a handwritten $\in$ symbol.
