To quickly assess the difficulty of the text, read a short excerpt:
(=212° P.,) 3.5060 grams, which carefully burned, left 1.6960 grm. of oxyd of lead combined with the larger quantities of sulphuric acid, phosphoric acid and chlorine. The organic matter, represented by the loss in burning equaled 1.81 gram, or 1.51 per cent. In order to gain some idea of the nature of this organic matter I precipitated again two thousand grams of fresh juice, collected the precipitate upon a filter, and washed it once with cold dis- tilled water ; suspended it afterwards in co...ld distilled water, and treated it with washed hydrosulphuric acid gas, till an excess of gas was still perceptible after twenty-four hours rest. The solution obtained by the filtration and separation from the sul- phuret of lead was colorless, and settled by boiling a small quantity of coagulated albuminous matter, it contained all the sulphuric acid, phosphoric and oxalic acid of the juice, besides a small quantity of another organic acid, which I according to the properties of its compound Avith lime believe to be tartaric acid.
