Note 280 — DIVING-BELL.
William Johnston translation
“The divers of Astracan stepped from the warm bath into the water, in which they could not continue above seven minutes, and were brought back from the water, cold and benumbed, to the warm bath, from which they were obliged to return to the water again. This change from heat to cold they repeat five times a day, until at length the blood flows from their nose and ears, and they are carried back quite senseless.”—Gmelin’s Reise durch Russland, ii. p. 199.
