To quickly assess the difficulty of the text, read a short excerpt:
This gives a yellow precipitate in sections containing tannins. Ammonium Vanadate. — This is used as a test for solanin. The sections are treated with a solution prepared by dissolving I part of ammonium vanadate in 1000 parts of a mixture of 98 parts of concentrated sulphuric acid and 36 parts of water. If solanin is present, a yellow color appears, which merges into orange, then different shades of red, and finally into violet, and then all color disappears. ANILINE OIL-^BERLIN BLUE 287 Anili...ne Oil. — Excellent for dehydrating sections, since it will dissolve about 4 per cent, of water and may be kept dehy- drated by a small piece of solid KOH which is insoluble in it. The sections may be transferred from the aniline immediately into Canada balsam. Aniline Sulphate. — Make a saturated aqueous solution. As a test for lignified membranes mount the sections in the solu- tion and add a drop of sulphuric acid, and a yellow color is given to the lignified membranes. Or pour sulphuric acid slowly into aniline oil until a pre- cipitate is produced throughout and then add water until the precipitate is dissolved.
