Into this limpid juice, thus extracted from the moss, in combination with lime, a solution of sul¬ phate of iron was poured, and immediately a black inky precipitate ensued. It did not occur to me to try this experiment with powdered chalk or carbo¬ nate of lime: But it appeared that the quicklime had extracted from the wet moss a considerable por¬ tion of tanin, which occasioned the inky precipitate when it came in contact with sulphate of iron. Perhaps this may in part account for the action of lime in destroying the astringency of moss.”
