title: Dense particles in subcutaneous collagen fibrils.
abstract: Electron microscopy of unstained, fresh air-dried spreads of the subcutaneous connective tissue disclosed dense particles (6-20 nm in diameter) at the dark bands of collagen fibrils with 67 nm periodicity. The particles appear to consist of chlorides from the X-ray microanalysis of collagen fibres.
