J. & H. J. Green Solar Radiation Thermometer

<< >>
This is a non-standard, possibly experimental, glass thermometer with a spherical bulb. Its scale extends from about 60 to 135 degrees Fahrenheit, and is marked “J. & H. J. Green, N.Y.” and “Signal Service, U.S. Army No. 11.” It is enclosed in a glass tube that, according to Green trade literature, was “very perfectly exhausted of air and moisture.” It dates from the period 1879-1885 when James and Henry J. Green worked in partnership.
