with fine earth; and by the middle of Juy these
were found full of eggs gTubs, of cne-quarer inch

After carefully collecting these eggs &C., they were

PROPERTY OF WASHING BUrrER.--In reference TO
the preparation Of good table butter, Dr. WIkens
.Pogarth remarks that there is rather common be-
baf that the process of washing Injuries its peculiar
fine flavor and renders the butter more pershable
The former part of the proposition DR.. Pogarth ad-
n,its; vet thinking the of fresh water indispen
sable for removing the milk and hardening the but
ter he recommends its application directly IN the
ehurn, avoiding working and kneadlng by hand or
spatula Butter which keeps well is made in Hol-
stein by repeated sailing and heavy pressure, with
cut the of water; but it is too salt to be con-
sidered fue table butter.
Removal OF OILY MATTER FROM Wool
pIC BY HYDRO-CARBON Notwithstanding 10
simonin and Coffin, by passing vaPor of any
Of the light hydrocarbons produced IN the rec
ii6cation of petroleum las naphtha, &c) through
wool, horse hair, feathers &c, placed on suitable
open frames it will take up the oily matterand re-
tain it in solution after condensaton. BY distilling
this solution and either passng~the vapor through
in,sh portions OF WOOL &c, or cOndensing it, the
oily matter is left as a residue, which can be puri
fed and utilized. Treatment with vapor is more
effective than with liquid bFdro-carbon, since 1t
comes into more intimate contact with the substance
10 he purified.
AouFoUs SOLUTIONS or SHFLLAC.-AccOrding to
waIzan an aqueous solution of shellac may be made
hy breaking it up aud covering 1t with a concen-
trated solution of carbonate of ammonia, and boiling
II upon water bath until the amlnoniacal smell has
entirely disappeared. More of the solution is then
added and the boiling continued until the shellac
forms coherent sp0nge-like mass The carbonate
If ammonia is then expelled by further boiling and
the mass will readily dissolve by pouring boiling
water upon it, A kind of soap will be found floating
npon the surface which may readily be removed by
straining The solution spread on paper. &c, dries
rapidly aud leaves thin, lustrous, adherent film OF
siellae.
Removal OF GUM FROM SUK.-FOrmeFlT raw silk
was boiled in bags in solution of soap, whereby its
gloss was frequently injured. Afterwards this pro-
cess was modified by exposing the silk to the action
of st.ano after having been mpregnated with Mar
srilles soap The removal Of the gum from raw silk
has since them been still further simphed and re-
guires neither boiling nor steaming. The silk, sus-
PENDED upon sticks, is moved about for quarter OF
an hour in "a hot bath, containing ID of soap for
every pound of silk, and then treated in the same
way i'm second bath containing only One-ffth pOund
af soap for a pound of silk. Simple this proceed
ing is ii has nevertheless been found successful IN
rendering the silk soft smooth and of higher gloss.
OZoEFRITE CANDIEs.-At the exhibition Of chem
ical and allied products at Dublin, held during the
past Summer the various forms of candles were
prominent articles, and especially those made of
ozokerite. This is fossil first mentioned by Meyer,
who discovered it in Moldavia, in connection with
the mines Of rock salt The material nsed by Messrs
Field d Co.. who exhibited the candles in question,
is obtained by them from the Carpathan Mountains,
aud the candles are said to be of great beauty They
have very high melting point and do not soften nor
bend at an ordinary temperature. They also exceed
any other candles in their Illuminating power. Thus
74 grains of ozokerite gave much light as 1000 of
the best speDaceu 79S to 591 of parafine, and 1850
Of wax candles.
GRENADE. A NEw DYE-sTUFF.--A secondary pro-
duet OF the manufacture Of fuchsine employed for
some time in dyeing wooden goods under the name
Of oesise aniline orsee, &c. has of late contained
impurities in the form Of insolube foreign substances
which has suggested the effort TO render it suf |
6eiently pure to warrant its use with the finer
fabrics. A dye-stuf, named grenade, has been pro-
duced at the factory Of Knosp in Stuttgart which is
said to give pure garnet brown free from the dirty
bluish-red tint of cerse and other substances sub
stituted for archil and which by combination with
picric acid turmerc, &c, can be made to give any
shade Of brown. The brllancy of the color sur
