The following graph from Sea and Shore Fisheries Bulle- tin 11 shows the death rate in fresh natural sea water. No lobsters died in the first seven days. But thereafter the death rate rose somewhat until after twelve days the mor- tality sharply increased. All fifty lobsters in the test were dead in thirty-two days. The water was cooled to 45°-50°F.
