incomplete bar

OK, I seem to have figured out about writing simultaneous voices one of which is double-stops. But another question--is it possible to write an incomplete measure (and I don't mean just a pickup)? I am quoting a bar plus part of a second bar of an existing piece. I do not want to quote the whole second bar, nor do I want to "falsify" the note values of the original material by making half-notes or whole notes out of them when they weren't originally. Or in other words, I want the last bar to have no end, no bar line, just left hanging in the middle. Is this at all possible?

Thanks
