Joseph Long was an instrument maker who began in business at 20 Little Tower Street, London, in 1820. Four years later he introduced a new saccharometer designed for brewers. This example is of that sort. It is made of brass, and marked "Long's Improved / Saccharometer" and “Sold by / T. King / Clare St. Bristol.” The wooden sliding rule is marked “J. LONG . . . LONDON.” The back of the thermometer is brass, graduated from 40 to 220, and marked “BUSS / 33 HATTON GARDEN / LONDON.” Thomas O’Dempsey Buss (fl. 1847-1883) was a successor to Bate.
