in various strata of the sea. Under ordinary conditions, such readings are obtained using some pretty complicated instruments whose findings are dubious to say the least, whether they’re thermometric sounding lines, whose glass often shatters under the water’s pressure, or those devices based on the varying resistance of metals to electric currents. The results so obtained can’t be adequately double-checked. By contrast,
