The _milk_ was found to be of a yellowish colour, resembling that of
colostrum or beestings, more thick, as well as sweeter and more savoury
than the ordinary milk: a superiority it derives from the concentration
it has undergone. It may be affirmed that milk of this kind, though
prepared nine months before, may supply the place of the greater part
of the cream sold at Paris. What however will appear more extraordinary
is, that this same milk having been put into a pint bottle which
was uncorked a month before, to take out a part of it, and re-corked
afterwards with little care, was also preserved, having undergone
scarcely any change. At first it appeared to have somewhat thickened,
but a slight shaking was sufficient to bring back its ordinary
liquidity. I present it here in the same bottle, that you may convince
yourselves of a fact, which I should have had a difficulty to believe,
if I had heard of it only, without having the evidence before me.
The _whey_ which we afterwards examined, presented some singular
appearances not less astonishing. It had all the transparency of whey
recently prepared. Its colour was deeper, it had a stronger taste,
and it was somewhat thicker. It underwent a change also with less
rapidity, having been exposed to the air at the end of a fortnight; for
a bottle opened six weeks ago, occasionally shaken, and ill corked, did
not begin to lose its transparency till the end of a fortnight. Its
surface at the end of more than a month was covered with a somewhat
thick mouldiness, which when carefully taken off, left the remainder
still possessing the flavour of whey.
The _green peas_ and the _Windsor beans_, boiled with the attention
enjoined by Mr. Appert, furnished two excellent dishes, which the
remoteness of the usual season of such vegetables appeared to render
still more finely flavoured and agreeable.
Whole _cherries_, and _apricots_ cut in quarters preserved a great
part of the flavour they had when gathered. It is true Mr. Appert was
obliged to gather them before they were quite ripe, lest they should
lose too much of their figure in the glass jars in which they were
preserved.
The _currant_ and _raspberry juice_ appeared to us to enjoy almost
all their qualities. We found the aroma of the raspberry perfectly
preserved, as well as the somewhat aromatic acid of the currant. Their
colour only was a little faded.
