A METHOD OF SEPARATIE6 NICOTINE PROM 1HE
SmoxE OF ToBAcco.-In order 10 separate nicotine
nom tobacoo-smoke, NJ. Ferrier proposes to furnish
pipes and cigar-holders with tube containing pecu-
Early prepared cotton. lie hopes by this arrangement
10 obviate the inconvenience and dangers incident 10
the occasional habitusl practice Of tobaccosmokng.
To prepare the cotton il il soaked in solution of tan
min, and then dried in the air. When the smoker
draws the air through the bowl Of his pipe, the
leaves Of HE cigar, current Of gas and vapor If
formed consisting Of air with of nitrogen, Of
caIbonic acid, and vapor Of water, products of the
combustion Of the outer layer of the tobacco and Of
the empyreumatic matter produced from the portions
of tobacco adjoining the btning surface. When these
various products come in contact with the prepared
cotton the latter moisened by the vapor of wate
and the annn retains the nicotine IN chemical comb
nation. The distinguished chemist Cahours has re-
peated Terriers experiment and confirmed Lis results
He lie convinced that by the use Of the cotton pre-
pared by NJ. Ferrier, and removed sufficiently often
che products Of the combustion and dstatioR Of to-
baeco entirely deprived Of nicotine. BarTal,
without dsputing the result of Ferriers experiments,
objects that nicotine IL not capable of uniting with tan
nin and that the latter substance is moi less injurious
than nicotine. The conclusion to be derived from
these Investigations seems 10 be that tObacco-smoke
which has passed over prepared cotton IL not ALSO
lntely deprived Of its virtue. Besides, ii yet remains
20 be ascetained whether smoke thus deprived of is
nicotine would still have the properties required by the
smoker. Says BarTeswin, it woald seem that if to
baceo were employed only for its smoke and no. for
the physiological effects which the smoke produces, it
would be easy to substitute for some inoiensye sub
stance or even 10 abstain entirely from its use unles
indeed the mere mechanical operation Of breathing gas
through the tube Of pipe, or cigar is not all the pleas
Of smoking, the odor Of tobacco aside from its
special influence does have sufficient attraction.
II il not difficult TO conceive that persons may become
Infatuated to the of tobacco thus deprived Of its
peculiar qualities when we remember that cllccory
has become a regular article of consumption, being
used to make q coffee which may be truly considered
rs destitute of all virtue.
DAIRY IWPRovENESTs.-At q late meeting OF a
Farmers Club in England, DR.. VOelcker, Chemist to
the Royal Agricultural Society Of England, commune
Gated the fact that in the ordinary process Of manuc
tm1ng cheese not less than % per cent Of the casen
ana oner originally present in the milk are lost in the
whey Dr. Voelcker expressed the opinion that this
ioss may oe avoided by proper modification Of the
process OF cheese-making. The Doctor promised 10
coinhu al future meeting the details of bis i'm
proved method By the use Of which saving of 20 TO
i' POI N'N :" uo rVuet OF cheese-daiiies may be
effected He claims in fact to be able to make four
eheeses from the quantity Of milk ordinarily employed
to produce three.
