MAGICAL TRANsuUTAT1ONS.-Iu few
shavings Of logwood III common water, and
when the liquor is sufficiently red. pour it
into a bottle Then take three drinking
glasses, and rinse one Of them with strong
vinegar; throw into the second a small
quantity Of pounded alum, which will not
be observed if the glass has been washed,
and leave the third without any preparation.
IF the red liquor in the bottle be poured into
the first glass, it will appear Of a straw coli
or if into the second, it will pass gradually
! from blush gray to black, when stirred with
key or any piece of iron, which has been
| previously dipped in strong vinegar. In the
third glass, the red liquor will assume vio-
let tint.
BEAUTIFUL ORNAMENT FOR ROCM.-
Dissolve in seven different tumblers. contain
| ing warm water, balf ounces of sui pilates Of
! iron, copper, zinc, soda, alumine. magnesla,
and potass. Pour them all, when completes
/ ly dissolved, into a large evaporatng dish
| of Wedgwood's ware, and stir the whole with
glass rod place the dish in q warm place,
where it cannot be affected with dust, or
where it may not be agitated. When due
evaporation has taken place, the whole will
! begin to shoot out into crystals. These will
| be interspersed in small groups and single
! crystals amongst each other. Their color
aud peculiar form of capitalization, will dis
! tiuguish each crystal separately, and the
whole together remaining in the respective
! places where they were deposited. will dis
| play very curious and pleasing appearar &C,
Preserve it carefully from dust.
! SYMPATHETIC INK.-The most curious of
all kinds of sympathetic ink, is that from
cobalt. 1t is very Singular phenomenon,
that the character of figures traced out with
| this ink, may be made to disappear at pleas
ure; this property is peculiar to INK obtained
| from cobalt for all The other kinds are at
| first invisible, until some substance has been
! applied to make them appear !; but when
once they Lave appeared they remain. 10
prepare this lax, take zaffre, and dissolve it
| in nitro muriatic acid, I'LL the acid extracts
| from it the metallic part Of the cobalt which
! communicates to the zaffre it's blue color ::
! then dilute the solution, which is very acrid,
with common water. If you write with
| this liquor on paper the characters will be
! invisible but when exposed to a sufficient
! degree of heat, they will become green
! When the paper has cooled they will disap-
! pear. Observe, if the paper be too much
| heated. they will not disappear at all. By
! this kind Of ink the following amusing trick
may be performed: Write on several leaves
/ of paper, with common ink, certain Dum-
! Der of questions, and between each question
write the answer with the above kind of ink
| The same question must be written on sew
eral pieces of paper, bat with different an
swers, that the artifce may be..better conceal~
| ed. Then provide d box to which you may
! give the name of Sybil's cave, Containing in
| the lid plate Of iron made very hot, in or
der that the inside Of it may be heated to a
! certain degree. Having selected some Of
! the questions, take the bits of paper contain
/ ing them, and tell the company you are 60
| ing to send them to the Sy bill, or oracle, to
! obtain an answer introduce them into the
| heated box, and when they have remained
! 10 it some minutes take them out, and show
| the answers which have BEEN written
| Take care, soon to lay aside the bits of pa
| per; for if they remain long in the hands Of
those to whom the trick is exhibited, they
would see the answers gradually disappear,
| as the paper became cold
