Abstract
THE following note contains a short description of the principle of a new type of microphotometer, the details of which will be published elsewhere. The main feature of this new device is that it gives a practically instantaneous record of the blackening curve, that is, the distribution of transparency of a photographic plate or a similar object along a straight line, which appears on a fluorescent screen and therefore permits a quick visual survey of the blackening distribution in a whole plate. The new instrument is comparatively small, easily transportable from one place to another, and it contains no delicate or expensive mechanical parts. It can, if necessary, be put together in any laboratory workshop from parts of existing apparatus.
