This work results from the confluence of two programs of investigation and, naturally, from a common interest in ecological problems. The Institute of Forrestry and Plant Biology had utilized, besides other methods, the analysis of principle components of correlation matrices for the study of vegetation and have at their disposal adequate programs for the treatment of a great volume of data. For its part, the Institute of Fishery Investigations is interested in very similar problems of classification, standardization and calculation, and has collected a large quantity of data on the cell density of different species in the plankton and environmental factors. Among these, a series relating to the sea near the Antillies appeared very adequate for trying a test, for the great quantity of samples which it includes and the extensive range of localities, dates and depths from which said samples come.
