Beschreibung:
A micro-pipette for the ultra-mechanical analysis of soils is described. The sources of error in the usual centrifugal methods are discussed and the new method is shown to be simple, accurate and capable of being adopted as a routine method even in the most moderately equipped laboratories. The treatment of the soil with alkaline permanganate to destroy humus does not affect the inorganic soil colloids.
