    This is a systematic and thorough exposition of quasi-proximities from the point of view of grills. Earlier work for basic symmetric proximities was initiated by \textit{W. J. Thron} [Math. Ann. 206, 35-62 (1973; Zbl 0247.54027)]. The authors show that many of Thron's results remain valid for quasi-proximities. Then the authors use the theory to construct \(D_ 0\)-extensions, including compactifications, of \(D_ 0\)-closure spaces. They conclude by an examination of Riesz's remarks in the context of quasi-proximities.
