Note 3 — Chapter I · March 15 to June 22, 1895
Reading edition
On April 18th, when the doctor and I were out looking for a suitable piece of ice for determining the specific gravity of the ice, we observed a remarkable drop of water hanging under a projecting corner of a large block of ice, reared up high by pressure. There it hung, in the shade, quivering in the fresh breeze, although the thermometer registered about -23° of frost. “That must be very salt,” I said, and tasted it—“Phew!” It was salt in very truth—rank salt, like the strongest brine.
