The bark is rough and dark-coloured externally, but internally 
consists of numerous regular whitish or yellowish layers, and 
contains a large quantity of sri net lime and other mineral 
ratte It is also rich in sapon regen able soap-principle 
somewhat widely diffused in satin: families of plants. According 
to Le Beuf, quillaia bark is the best material for preparing saponin 
for technical Sane 
Quillaia bark has recently been proposed by Dr. R. Kobert 
tigi Gu .» p. 606, from Centralbl. fiir Klin-Med.) as a substitute 
as found that the two glucosides occurring in 
—- i a are present in omen bark in almost five times the pro- 
portion in which they occur in senega. As quillaia bark contains 
a tolerably constant Sropereioa of the glucosides, and as it also 
contains a considerable amount of sugar, which gives the decoc- 
tion a sweet taste, and is much cheaper than senega, it ofters 
certain od vantages over that drug. The experiments of Dr. Kobert 
are said to have proved that patients bear quillaia better than 
senega, that it rarely produces vomiting or diarrhoea, and is readily 
take children, while its ex petit action is beyond all 
question. The preparation used by Dr, Ko aber ae a decoction 
00 0 
dose was a teaspoonful for children and a tabtospoostt for adults. 
e use of guillaia is contra-indicated in inflammation of the 
intestines or stomach, or in ulcerated states of the mucous 
membranes. (Pharm. Journ. xvi. [3], 289.) 
In Chili, quillaia bark is reduced to powder and used as a 
substitute for soap in washing sloth two ounces of the bark 
being sufficient to wash a dress. It is also said to remove all 
spots or stains, —_ to a a remarkable lustre to wool. Further, 
it is used to wash the hair, for which pu rpose it is powdered 
between stones, then rabtied with the hands in water, making a 
foam like soap. 
Although quillaia bark is not officinal in this country it is 
included in the last revision of the U.S. Pharmacopoeia. It is also 
officinal in the new French Codex under the title of Bois de 
Panama, but the tincture prepared from it is chiefly employed 
as an emulsifying agent for the preparation of mi of variou s 
sens es oils. A powder sold under the name of * emulsine’ 
appea consist essentially of saponin, or the mponistons 
Gehiniple of quillaia bark. (Pharm. ab xvii. [3], 350.) 
The late Dr. Schomburgk wrote " follows after receiving seeds 
at the Botanic Gardens, Adelaide, i 
“Through the kindness of Sir Tosenh Hocker I received some 
seed of this remarkable tree. Zhe bark consists of numerous 
layers, Prisca a much carbonate of lime and other mineral 
matters, which render it so heavy "thst it ae in water, It is in 
common use in Chili instead of soap, and has been introduced 
into England and recommended as a substitute for soap, especially 
for washing she goods, silks and delicate coloured fabrics.” 
Mr. M. A. Lawson, F.L.S., gave the followiug account of plants 
raised on the N ileivis i in 1884 :— 
Quillaja saponaria. A few only of the seeds of this Rosaceous 
plant which were sent from Kew have germinated, The plants,
