rinse with a little alcohol. — Forms white crystals, fusible, insoluble in 

 water, readily soluble in alcohol; yields with acetic acid a readily 

 soluble salt, with hydrochloric, nitric and sulphuric acids salts 

 which dissolve sparingly in water and in acids. 



Juiliperill. Resinous substance of the fruits of Juniperus 

 communis and other species of Juniperus. Effect a distillation 

 with water, after the fruits have been macerated with cold water; 

 strain the remaining mass hot, let cool, collect the sediment, treat 

 it first with cold, then with boiling alcohol, and distil off the 

 alcohol from the united tinctures. The remaining liquid throws 

 down successively wax, resin, at last Juniperin as a yellow jiowder, 

 which conglomerates like a resin. This has to be washed and 

 gi'ound up with water, whereby it dissolves in 60 }iarts of water 

 and passes, when this solution is shaken with ether, into the 

 latter, remaining after the evaporation of the solvent as a light- 

 yellow, brittle, tasteless mass, which burns with the odour of 

 jimiper, dissolves in ammonia with gold-yellow, in concentrated 

 sulphuric acid with light-yellow colour. 



Raeilipherid, In the root of Alpinia Galanga. Exhaust 

 with ether, evaporate the liquid and recrystallise in alcohol. — 

 Light-yellowish lamella? of mother-of-pearl lustre, without smell 

 or taste, fusible by heat and decomposing afterwards; scarcely 

 dissolving in water, in 25 parts cold ether, in 50 parts cold 

 alcohol, better in both when hot, also a little in acids, readily 

 in caustic alkalies without change. It is decomposed by concen 

 trated sulphuiic acid under various changes of colour. Consists 

 of 65-32 C, 4-40 H, and 30-28 0. 



KaWallill=:METHYSTICIN. 



KillOtauiliC Acid. In kino, an induration of the sap exu- 

 dated from incisions of the stem of Pterocarpus Mai-supium. It 

 is regarded by some as different from, by others as identical with, 

 gallotannic acid. 



[Kinotannic Acid has been found by J. Wiesner to exist in 

 combination with a kind of gum in the Eucalyjitus kino, a 

 spontaneous exudation of the stem of Eucalypts. Pyrocatechin 

 was invariably found to be present in small quantities, and in a few 

 instances also Catechin.] 



Rokiim-Biitter=:BRiNDONiA Tallow. 



lioussill = C26 H22 O 5 . The active ingredient (vermifuge) of 

 the kousso-flowers (from Hagenia Abyssinica). Digest with alcohol, 

 containing lime; press, let siibside, filter, draw olf the alcohol, allow 

 the residue to rest warm and uncovei'ed for some time, in order to 

 remove the last traces of alcohol, filter, oversatiirate slightly with 

 acetic acid, collect the deposit, wash with cold water, and dry with 

 a very gentle heat. — White, often a little yellowish powder of
