Mix eautiously by tlic aid of heat, perfectly pure Sulph. acid, aud Calvert's Carbolic acid No.2,in the proportion of 49 parts by wt.of the former to dii of the latter. Put into flask with narrow neck, into which is inserted a thermometer, and cover by means of a paper diaphragm to prevent escape of fumes; place on a sand-bath and Jieat r/raduaUi/ until the temperature reaches 290° P. Keep at this point 10 or 15 minutes, then let gradually cool. Sp. gT. 1'288; very sol. in water, alcohol and ether. See Sulpho-carbolates under the bases. AciDirji Tannicum. B. Tannin or Tannic Acid. B. Ex- l^ose powdered galls to a damp atmosijhere for 2 or 3 days. Add sufficient ether to form a soft paste. Leave in a well-closed vessel for 24 hours. Then quickly enveloping in a linen cloth, press strongly to separate the liquid. Powder the cake, mix with ether to whicli l-16th of its bulk of water has been added, to form a soft paste, and express as before. Mix the liquids, and with the aid of a little heat let them evaporate to a soft extract. Place it on earthen plates, and dry in hot-air chamber at a tem- perature not exceeding 212° P.

When the tartrate of lime has subsided pour off the liquid, and wash the tar- trate with distilled water until it is rendered tasteless. Ponr sulphuric acid f=xiij, first diluted with 3 pints of the water, on the tartrate of lime, mix thoroughly, boil for half an hour with repeated stirring, and (illcr thVoiigh calico. Evaporate the filtrate 'at a gentle heat until' it acquires the s])eeiiic gravity of 1-21, allow it to cool, and then scpiirate and reject the crystals of sulphate of lime which have formed. Again evaporate the clear licpior till a lilin forms on its surface, and allow it to cool and crys- talli/e. Jjastly, purify the crystals by solution, filtralmn (if ne(;essury), and recrystalli/.ation. 7^> gr. dissolved in
