Analyse D’Une Population de Cellules Spheriques

The first part of this paper is devoted to the analysis and verification of methods derived from that of WICKSELL which allows deduction of the cell volume histogram from the histogram of cell section diameters. The second part emphasiezs the difficulties involved in the interpretation of the cell volume histogram: if it is multimodal can one conclude that it is composed of sub-histograms defined by some biological reality ? And if it is unimodal does this mean that it represents a single population or a superimposition of gaussian populations. In the last case, how does one determine the statistical law attributed to a subpopulation ?
