ART. XXXVIII. —CHEMICAL EXAMINATION OF THE BARK 
OF QUILLAIA SAPONARIA. By MM. Henry, Jr. , and Boutron 
Charlard. 
MM. L. Eveille, member of the Royal Academy of Me- 
dicine, some time ago, sent to us some pieces of bark col- 
lected in Chili, and produced by a tree known by the name 
of Quillaia saponaria, which he desired us to examine. It 
is the result of the experiments upon it which we now present 
to the Academy. 
There is found in the abridgement of the History of Chili 
by Molina, a detailed description of the tree which furnishes 
this bark. It is thus expressed: Quillaja Saponaria, gener. 
nov. Folia alterna, ovato-oblgnga indivisa, denticulata, 
sempervirentia, petiolata. Pedunculi axillares; flores 
masculi et feminei in eadem ramo; calyc. foliolis oblongis 
persistentibus ; stam. capillaria, long, calycis; antheras 
subrotundae; germ, subrottindum; styli subulati, capsula 
subquadrata.
