''IIow Is modern ice-croam madeP"
was the question propounded to
prominent chemist by the Herald re-
porter.
"Oh, wouldn't be too hard on the
girls by telling you, replied the man
Of science, "because they would do
prive themselves Of their favorite luxury
should they know what they eat"
"But it would be a blessing for the
small-salaricd boys" suggested the
scribe. Two dishes Of ice-cream for
the girl and lemonade with q stick in
It, and cigar on four evenings of cali
Ing time each week would be Sl.60 or
over $40 during the season. That
amount would purchase beaver over
coat with sealskin cuffs and collar.
Think OF itp'
The Professor was not proof against
such an example Of domestic arith-
mctic, and he relented. ''I noticed. "
he said, that DIR. BARLEY. Of Brook
lyn, publishes n statement in which he
says that he finds very subtle poison
ptomaine-in ice-creap during this
season Of tho year. The formation of
this deadly alkaloid, he thinks, is prob
ably the result of decomposition in some
gclatinous matter of animal origin,
which enters into the cream as we get
il now. | rather think that very little
cream, II any, enters into the manufact-
urc of modern ice-croam. Milk. eggs,
corn starch and thickening OF gcla-
tine are the principal ingredients, so
far rs | know That gives a very ap-
petizing ice-cream, should think, and
Il is no wonder that they can sell the
stuff at a dollar the gallon"
"l understood that cotton seed oil Is
used by some of the manufacturer" re-
marked the reporter
"Worso than that" was the reply.
"They use lard-oil, which is nothing
else than the 'oleo oil Of the butterine
trade. Contrary to the butter-making,
though, the oil is not chilled by being
run Into tanks of cracked ice, but
is warmed In steam jacket-kettles TO
nearly the boiling point-two hundred
degrees Fahrenheit Tho milk which
is purchased from the creameries, Is
what may he calledI skinned on both
sides and partially in the middle-is
also heated to about one hundred and
seventy-fve degrees Fahrenheit thus
nearly equalizing the specific gravity of
the two principal ingredients. To every
five gallons of milk, costing twenty
cents, is added eight ounces OF oloe oil.
After this is thoroughly mixed there is
an addition Of sixteen ounces of potash
starch, which is cheaper than corn
starch, and one-half ounce Of gelatine.
This whole deleCtable matter is then
boiled in copper vacuum pans. Tho
ingredients unite chemically much
better in vacuum than under atmos-
pheric pressure, as would be the case in
open vessels. Again the boiling point
is lowered, and thus Is prevented what
has proved such an annoyance in but
ter-making-the suct flavor Whatever
should remain of that nasty flavor in
so-called ice-cream is killed by tho
favoring extracts, mostly vanilla.
Then the mess Is congcaled In ordinary
freezers, and your msdern ice-cream Is
ready for market. The average van
lila extract is made from the sprouts
of the spruce pine, and better kind
is made from the tonka bean"
ptomaine Is not only in cured meat but
also in icc-cream which our deaT girls
consume with such avidity?" This by
the reporter
"PtOmaine is found in all articles oi
food which are In certain stages of de.
composition" said the Professor. with
a laugh, "but then II Is not an animal
