Perhaps not. But I would strenuously advise you not to place too much

reliance on your slight chemical knowledge in medical matters. I do not

know why whey is not separated from curd by rennet, or by an alkali, for

the purpose which you mention; but I strongly suspect that there must be

some good reason why the preparation by means of wine is generally

preferred. I can, however, safely point out to you a method of obtaining

whey without either alkali, rennet, or wine; it is by substituting lemon

juice, a very small quantity of which will separate it from the curds.

Whey, as an article of diet, is very wholesome, being remarkable light

of digestion. But its effect, taken medicinally, is chiefly, I believe,

to excite perspiration, by being drunk warm on going to bed.

From whey a substance may be obtained in crystals by evaporation, called

_sugar of milk_. This substance is sweet to the taste, and in its

composition is so analogous to common sugar, that it is susceptible of

undergoing the vinous fermentation.

CAROLINE.

Why then is not wine, or alcohol, made from whey?

MRS. B.

The quantity of sugar contained in milk is so trifling, that it can

hardly answer that purpose. I have heard of only one instance of its

being used for the production of a spirituous liquor, and this is by the

Tartan Arabs; their abundance of horses, as well as their scarcity of

fruits, has introduced the fermentation of mares’ milk, by which they

produce a liquor called _koumiss_. Whey is likewise susceptible of being

acidified by combining with oxygen from the atmosphere. It then produces

the _lactic acid_, which you may recollect is mentioned amongst the

animal acids, as the acid of milk.

Let us now see what are the properties of curds.

EMILY.

I know that they are made into cheese; but I have heard that for that

purpose they are separated from the whey by rennet, and yet this you

have just told us is not the method of obtaining pure curds?

MRS. B.

Nor are pure curds so well adapted for the formation of cheese. For the

nature and flavour of the cheese depend, in a great measure, upon the

cream or oily matter which is left in the curds; so that if every

particle of cream be removed from the curds, the cheese is scarcely

eatable. Rich cheeses, such as cream and Stilton cheeses, derive their

excellence from the quantity, as well as the quality, of the cream that

enters into their composition.

CAROLINE.

I had no idea that milk was such an interesting compound. In many

respects there appears to me to be a very striking analogy between milk

and the contents of an egg, both in respect to their nature and their

use. They are, each of them, composed of the various substances

necessary for the nourishment of the young animal, and equally destined

for that purpose.

MRS. B.

There is, however, a very essential difference. The young animal is

formed, as well as nourished, by the contents of the egg-shell; whilst

milk serves as nutriment to the suckling, only after it is born.

There are several peculiar animal substances which do not enter into the

general enumeration of animal compounds, and which, however, deserve to

be mentioned.

_Spermaceti_ is of this class; it is a kind of oily substance obtained

from the head of the whale, which, however, must undergo a certain

preparation before it is in a fit state to be made into candles. It is

not much more combustible than tallow, but it is pleasanter to burn, as

it is less fusible and less greasy.

_Ambergris_ is another peculiar substance derived from a species of

whale. It is, however, seldom obtained from the animal itself, but is

generally found floating on the surface of the sea.

_Wax_, you know, is a concrete oil, the peculiar product of the bee,

part of the constituents of which may probably be derived from flowers,

but so prepared by the organs of the bee, and so mixed with its own

substance, as to be decidedly an animal product. Bees’ wax is naturally

of a yellow colour, but it is bleached by long exposure to the

atmosphere, or may be instantaneously whitened by the oxy-muriatic acid.

The combustion of wax is far more perfect than that of tallow, and

consequently produces a greater quantity of light and heat.

_Lac_ is a substance very similar to wax in the manner of its formation;

it is the product of an insect, which collects its ingredients from

flowers, apparently for the purpose of protecting its eggs from injury.

It is formed into cells, fabricated with as much skill as those of the

honey-comb, but differently arranged. The principal use of lac is in the

manufacture of sealing-wax, and in making varnishes and lacquers.

_Musk_, _civet_, and _castor_, are other particular productions, from

different species of quadrupeds. The two first are very powerful

perfumes; the latter has a nauseous smell and taste, and is only used

medicinally.

CAROLINE.

Is it from this substance that castor oil is obtained?

MRS. B.

No. Far from it, for castor oil is a vegetable oil, expressed from the

seeds of a particular plant; and has not the least resemblance to the

medicinal substance obtained from the castor.

_Silk_ is a peculiar secretion of the silk-worm, with which it builds

its nest or cocoon. This insect was originally brought to Europe from

China. Silk, in its chemical nature, is very similar to the hair and

wool of animals; whilst in the insect it is a fluid, which is

coagulated, apparently by uniting with oxygen, as soon as it comes in

contact with the air. The moth of the silk-worm ejects a liquor which

appears to contain a particular acid, called _bombic_, the properties of

which are but very little known.

EMILY.

Before we conclude the subject of the animal economy, shall we not learn

by what steps dead animals return to their elementary state?

MRS. B.

Animal matter, although the most complicated of all natural substances,

returns to its elementary state by one single spontaneous process, the

_putrid fermentation_. By this, the albumen, fibrine, &c. are slowly

reduced to the state of oxygen, hydrogen, nitrogen, and carbon; and thus

the circle of changes through which these principles have passed is

finally completed. They first quitted their elementary form, or their

combination with unorganised matter, to enter into the vegetable system.

Hence they were transmitted to the animal kingdom; and from this they

return, again to their primitive simplicity, soon to re-enter the sphere

of organised existence.

When all the circumstances necessary to produce fermentation do not take

place, animal, like vegetable matter, is liable to a partial or

imperfect decomposition, which converts it into a combustible substance

very like spermaceti. I dare say that Caroline, who is so fond of

analogies, will consider this as a kind of animal bitumen.

CAROLINE.

And why should I not, since the processes which produce these substances

are so similar?

MRS. B.

There is, however, one considerable difference; the state of bitumen

seems permanent, whilst that of animal substances, thus imperfectly

decomposed, is only transient; and unless precautions be taken to

preserve them in that state, a total dissolution infallibly ensues. This

circumstance, of the occasional conversion of animal matter into a kind

of spermaceti, is of late discovery. A manufacture has in consequence

been established near Bristol, in which, by exposing the carcases of

horses and other animals for a length of time under water, the muscular

parts are converted into this spermaceti-like substance. The bones

afterwards undergo a different process to produce hartshorn, or, more

properly, ammonia, and phosphorus; and the skin is prepared for leather.

Thus art contrives to enlarge the sphere of useful purposes, for which

the elements were intended by nature; and the productions of the several

kingdoms are frequently arrested in their course, and variously

modified, by human skill, which compels them to contribute, under new

forms, to the necessities or luxuries of man.

But all that we enjoy, whether produced by the spontaneous operations of

nature, or the ingenious efforts of art, proceed alike from the goodness

of Providence. --To GOD alone man owes the admirable faculties which

enable him to improve and modify the productions of nature, no less than

those productions themselves. In contemplating the works of the

creation, or studying the inventions of art, let us, therefore, never

forget the Divine Source from which they proceed; and thus every

acquisition of knowledge will prove a lesson of piety and virtue.

Terminology

oxy-muriatic acid = chlorine

(proposed as an element in 1815: see Conversation XIX)

“columbium or tantalium” = niobium and tantalum

(the two elements always occur together, and were not recognized

as separate until much later in the 19th century)

phosphat of lime = calcium diphosphate _or_ calcium

(the element calcium was isolated in 1808, but is named only once

in this 1817 edition)

glucium = beryllium (Humphry Davy’s name for the element)
