Samples of sand were taken, either from the shore immediately above low water of spring tides, or from the bottom in a few inches of water.
With one exception no samples were dredged. The localities were few: Polesands; the north or estuarine shore of the Warren west of Salthouse Lake; the banks of the Salthouse Lake; a low-water stream on the Warren; near Lympstone; and (the dredged sample) within Exmouth Docks.
page 338 note * It should be noted that the figures given are the average of a large number of observations; but when, as at Exmouth, a great proportion of each species is represented by small individuals, the actual percentages which float will be much greater than given in the table, the relative percentages remaining constant.
