all-but-infinite

For, if the trap-door was absolutely air-tight, I cannot think that the supply of oxygen in the cellar, large as it was, would have been sufficient to last the girl twenty years, to say nothing of what her mother used up before death: for I imagine that the woman must have continued to live some time in her dungeon, sufficiently long, at least, to teach her child to procure its food of dates and wine; so that the door must have been only just sufficiently hermetic to bar the poison, yet admit some oxygen; or else, the place may have been absolutely air-tight at the time of the cloud, and some crack, which I have not seen, opened to admit oxygen after the poison was dispersed: in any case the all-but-infinite rarity of the chance!
