  The horizontal axis now represents a continuous flow of primal impressions, the vertical axes represent a selection of retentions (and in the case of F) protentions which accompany the primal impressions D, E and F. (A ‘selection’ because in reality, according to Husserl, a continuous stretch of consciousness consists of a dense continuum of primal impressions, each of which is accompanied by its ‘comet’s tail’ of retentions and protentions.) As can be seen, individual primal impressions are retained in later specious presents – as previously, increased ‘pastness’ is indicated by a greater number of asterisks. What goes for momentary primal impressions also goes for intervals: D-E is retained at F in the form of the retentional continuum E*-D**.
