You see + illustration. Now for a de-
scriptton Of it. a large tin fruit can viii do
as well as anything to contain the chemicals.
Take 4 can that Is well timed and sound.
Wherever old = has been used ii the seams
or joints cover with melted pitch while the
can IS warm. Tie inner cell IS of UnSlaze1
red CastLenware. This inner cell appears III
the engraving within the outer one on the
LETT OF the picture. The inner clay cell can
be got from pottery or ordered from a
country merchant. The pot5crs make them
OF all sizes. About one-thrd Of the upper
per5 of The cay cell must be made non
Torous. Coat it bY clipping it to this depth
into bowl Of melted ParafIfns wax. Give
ii two or thee coats, dipping for the next
one after the former gets cold.
SeI tie clay cell inside the tin one. FIJI
the space tetTesn the two with iron filings
and cuttings, OF, il il IS not convenient to
get these, use small nails, tacAs, scraps of
iron and piecas Of iron wire. No metal but
iron viii do, however, and il must not be
galvanized. Next come the chemicals Fill
the clay cell with solution of cGu5tic pot
asn. Pc careful not to let it touch the skin
or you Will be sorry. Keep it in a glass or
glazed crCckery vessel. Get then thick
strip or plate OF zinc. The upper end of it
must taper or thin and sharp, so that when
pas upward through the tight cover of the
cell Tae picture shows the thin end of the
zinc IS it masses up through the cover OF the
inner cell and loops over. This cover must
be OF cork Or wood, and very tight fitting, to
close the cell perfectly. 1t IS in the shape Of
q cork or stopper. Insert tine piece OF zinc
into the potash solution, Is shown in tho il.
IL. tradon, cork tight, and seal around and
over ;hs top CT the cork with wax or hot
pitch The covering must be perfectly air
tight.
Now all is ready. The clay cell is very
p rol-, and the potash solution passes
through its wall AMI nIing'es with the IRON
q lngs n the outer cell. 4. eats up the zine
