Abstract

The purpose of this paper is to present some contributions to physiological coprology. A sieve analysis system for the fractionation of faeces is proposed and results obtained by this system presented. Ash and crude protein were determined from the fractions. The other part of the paper deals with the extraction of faeces first with boiling 80 % ethanol and subsequently with boiling absolute ethanol. Crude protein and, in some cases, also ash were determined from the extracts. The use of such extractions as a preliminary step towards a more detailed examination of certain substances in faeces is proposed.
