It will be proper to observe, that the above experiment was made with the best home melted tallow. If foreign tallow, according to the general run of such, had been used, the produce would have been far from being so beneficially productive. However, a much smaller profit would be convincing, that the trade was not that losing one, which many ignorant and unfortunate adventurers have taught us, from their experience, to imagine.
Another experiment with the same quantity of tallow (4 lib.), but foreign, and above six years old, was tried with Petersburg pearl ash-ley. The operation was completed at three boils, and there was used 14 English pints of the ley; and the produce of the soap turned out to be seven and one half pounds.
