about three pounds, is to be put into an alembic of tinned 
copper, and thirty ounces of alcohol is distilled off by means 
of a salt water bath. The residue in the alembic is to be 
quickly poured into a porcelain capsule, and reduced to a thick 
extract by the same bath, in which state the veratria, on 
solidifying, becomes a brown powder. 
This veratria, which Professor Soubeiran distinguishes by 
the name of medicinal, has a resinous aspect, like that so well 
described by this able chemist, and an excessively burning 
taste, like that of a corrosive substance; so much so, 
that my assistant, having placed a portion upon his tongue, 
produced an excoriation on it, and likewise on his under lip, 
at least on that portion w 7 hich was touched by the veratria 
mixed with the saliva. 
Four pounds of cevadilla furnished six pennyweights of 
medicinal veratria.

ART. XVI. — NOTE UPON THE BARK OF CEDRELA 
FEBRIFUGA. By A. Richard. 
There is found in the forests of Amboina, Java, and Timor, 
a tree of majestic proportions, which sometimes attains the 
enormous height of two hundred feet. The natives of Java 
give it the name of Suren, and Rumphius (Herb. Jimboin.) 
has mentioned it under the name of Surenus. Dr. Blume, 
who for a long time resided in Java, of which he has pub- 
lished a Flora, has described it under the name of Cedrela 
febrifuga, because its bark eminently possessed febrifuge 
properties. Lately, Dr. Forsten has published at Leyden a 
Latin dissertation upon this bark, in which he has examined 
it under a botanical, pharmaceutic, and medicinal point of 
view. We have derived from this dissertation, which is well 
written, some of the details which we shall now present.
