Question:
Table V in Vol 35 records the width of Biddulphia sinensis cells (µm) grown in Erdschreiber-enriched seawater at 24°C, measured on successive dates in late August. Values are recorded on 24 August and on 25 August. Estimate the cell width at the midpoint between those two daily measurements by averaging the two recorded values.

Answer concisely. Cite the row/cell/section you used. State your final numerical answer clearly.
