title: [Unstained chromosomes. A simple method for observation].
abstract: A technique is described by which unstained metaphases may be observed using phase contrast microscopy. The cells are fixed on a cover slip which then is turned over and onto a slide, leaving a thin air layer sandwiched between. Observation in phase contrast shows metaphases comparable to those observed after Giemsa staining.
