soap to the natives, when there are
no convenicnces OF materials for
manufacturing ordinary soap. Ex-
amples ofthese are the Soapworts
(Sapind,,s :, so called from furnish
ing, either in the pulp of the fruit
or in the root or bark, vegetable
principle called saponine. Thus
the Hindus nse the pulp OF the
fruit OF .Sap'ndus detcryens for wash
ing linen. The capsula OF another
species, when bruised, forms suds
if agitated in the water; and the no
tives of india use this rs soap for
washing the hair, silk, etc. The
aril which surrounds the seed of a
So1th American species is used as
soap. The fresh bark of the root
OF Nounina polIactia. called ''ya'hoi'
pounded and moulded into balls, Is
used by the Pcruvians in place OF
soap The Canadian Naturalist,
from which onr account is taken,
also states that the bruised leaves
ri the European Solonaria o6icina'is
forms lather which much resem-

useful in removing grease spots.
The bark of Quita,a sopOnaria, OF
Central America, answers the same
purpose, and is used as detergent

imported largely into France, Bel

The account Of the session o
the French Academy of Sciences TO
the third of April is printed in tn
in the journal 0lic,el, the first tim
since the investment. of Paris, q
reports Nature. Prot. Simon New
comb, our eminent astronomer a
Washington, was present at the sit
ting, and read communication o.
the perturbati,ns in the motion G
the moon, owing to the attraction
of the planets The American as
tronomer proposes to solve thi
great question by a new method
The problem is to be solsed by on
hundred and fifty different equa
tons! NJ. Newcomb admits tns
it is quite impossible to solve
without some startling simplic'
tons The present communic'
ton is to show the Institute the we
through which the author hopes
realize these simplificatlons. 1t
not the final work, which, if it
successful, will prove that NJ. Ney
comb has made a great analytic
discovery. But in such q matt
experience pasSe science.
A new principle OF boiler Co
struction has been introduced
Mr.. Alfred Since, contrived for Il
purpose Of heating lighthouses, ct
Tbs popularity consists in the u
of only one pipe for the flow and +
turn of water, instead of two, as
usually the case. Mr.. Since fin
that the difference in specific gra,
ty between the hot and cold wat
is quite sufficient to keep the tv
currents perfectly distinct, and
maintain for any length Of time
free circulation at q uniform tel
perature. The principle is.
course. precisely the same as tn
of the polar and equatorial oce
currents. ~o
