Daily calendars noting temperature and fish births and deaths, 1949-1966, 1976 December 12-1978 January 2

The series contain week-long temperature gauge readout charts, 1955-1969, and daily calendars that note temperature readings (presumably for either the air temperature of the genetics laboratory or the water temperature of one or more tanks), and the number of fish births and deaths, 1949-1966, 1976-1978. The later records in the series, produced after Gordon’s death, were created under the auspices of Gordon’s successor in the Genetics Laboratory, Klaus Kallman.
