Abstract
The significance of the geometry of the optical system in extinction measurements for a liquid dispersion is emphasized. In particular, the mechanism by which light is lost by scattering in a transparency-meter in the sea is discussed. The strongly selective absorption of yellow substance is demonstrated. A new transparency-meter sufficiently accurate for measurements in clear ocean water is described. A long optical path in the meter is attained by multiple reflection between three concave mirrors of equal curvature. The depth is recorded by means of a new device.
