The candlemakers in Dalkeith routinely entered into one-year contracts with the Society of Fleshers to purchase the tallow from slaughtered cattle. This tallow was provided at a fixed price, and the candlemakers were entitled to examine it and receive a discount for any impurities they found. In 1799, the candlemakers sought, and obtained, a regulation providing for two appointees to search the tallow for impurities before it was transferred to them. The fleshers argued that this regulation should be suspended—or, at minimum, that they should receive a higher price—because the candlemakers were not entitled to receive purified tallow at the established contract price.
