We take the following extract from the late pas
emf office renort. It was written by doctor q
r. Jackson, of Boston: =,
A short time since, I was called upon by Mr.
Daniel W. Messer, who has taken out paen
for method of separating the bulls from co.,
ton Seeds to make a chemical analysis OF those
deprived of their hulls by his process ana ma
chinery. I was pleased TO undertake THIS IN
vestgation, and have extended my researches
much beyond what was required OF me- LOT .he
purpose of being able to contribute something
toward the agriculture of the southern otates;
I am aware of the fact, that cotton-seed OH
is now in New Orleans, but am informed that the
yield Of the unprepared and wooly seeds is very
small in comparison with what have been aoie
to obtain from those which have been hulled.
know also that professor Shepherd has given
an analysis of the ashes of unprepared cotton
seed but have not been able to find a copy
of his report, SO as to compare his results with
mine. ~.= e@.
The analysis hereafter given were made on
huled seeds. dried at212 degrees F.
Ny first analysis was made for the purpose
of determining the proportion of fixed oil con-
tanned in the seed; the next was chemical ex-
animation of the properties and composition OF
the coil -cake' or what remains of the seed at
ter the extraction of the oil; the third gives the
true elementary constitution of the oil cake; and
the fourth, the nature and proportions of the
inorganic principles, or mineral salts, contain
ed in the ashes of the incinerated oil cake, and.
also, that of the seed before the oil was sepa-
rated 1t will be understood by chemists, that
a vast deal of labor has been required to work
out all these results.
SEPARATION OF THE O1L.-In order to sepa-
rate the fixed oil, pure ether was employed, and
it was found that hundred grains of the dried
pulverised seeds yielded in one experiment,
80. 7, and in another 40 per cent of pure, fat
ty OIL By pressure, / was able, with a small
screw press, to obtain only 80 per cent. of oil,
but | have no doubt more powerful one would
have given larger yield. The specific gravi
y of the oil, which obtained from the ETHEREAL
solution, was 0. 923, water being unity. This

serving perfectly well for the fabrication Of ma

Is for making soap. 1t will also serve as sub
titute for olive-oiI in many cases, and perhaps
nay be eaten as salad oil, for it has no dis
lgreeable odor nor taste.
CHEMICAL EXAMINATION OF THE OH CAkE.--I
Iinseed oil cake is well known, both in Europe
md IN this country, as valuable food for cattle,
md as an excellent fertiliser worth from $40
o S45 per ton, for the latter purpose. On ex-
mining my cotton seed oil cake, found it pos
essed a sweet and agreeable flavor, and was
nuch more pure and clean than linseed oir-cake.
his cake, examined fer sugar, was found to
ontain !. grains. and for gum, 35 grains
we're obtained. Iodine gave noproof of the ex-
stence OF any starch in cotton seed, nor in the
III cake. Alcohol dissolves out the SUGAR
Which Is like that obtained from raisins, and is
,rape-sugar. Boiling water dssolves the gum
nd becomes very muciaginous. The gum is
receptacle from the water, by means of pure
lcohol.
Tie foregoing analysis of cotton Justify

Inch draws SO largely on the soil for phos-
hates. 1t will also be seen that, since the cot
'n-seed OIL cake contains nearly per cent of
ltrogen, and nearly 6 per cent. of hydrogen,
ne elements of ammonia are present in suffi
lent quantities to form about 10 per cent of {
