Dr. MeUonnel'B second Lecture
upen this Theme = Tho Analysis
RAnh.

W. G.. MoCopnel, NJ. d., delivered
his second lecture upon Digestion last
evening at the First Presbyterian
church. A g0pd-sized audience was
present aud the interest manifested
was greater than At previous lectures.
The doctor considered the "proximate
principles, those ingredients that
help to make up q Homogeneous body.
They exist in their own torn in bodies
and can be extracted by chemical pro-
cess without destroying their sub
stance. These principles are divided
in three classes. The ginorganic, the
crytalizing, and the organic.
The first class, or inorganic substan-
ces comprise water, salt, phosphate Of
lime, etc. Water Is most essential to
the human economy. A man will suf-
fer more from the lack of water than
the loss of food. Place some dogs in
pen, give some Of them water and the
others food, those giyen the water will
outlive those given the food four or five
days. Water ia composed of salt and
phosphate and carbonate of lime. Salt
is next in Importance. The deer have
a natural inclination for it. II main
tains the blood and fluids Of tho body
in proper condition ana impsrts pleas
ant flavor to food. Man cannot do
without the use Of it. Sheep which are
fed with salt have sleek and soft hides
and those that are not thus fed possess
q rough skin containing spots and lsss
of wool.
Phosphate Of lime enters in certain
proportions into the composition Of
bones at different ages. In the teeth
it is sS5 parts in a thousand and $50
parts in the bones. In childhood the
bones possess animal matter; in maturi-
ty equal parts Of earthly and lnimal
matter, and in old age eaitby mater.
child becomes bowleSged owing TO a
deficiency Of this matter.
The second class, or crystalizing sab
stances, comprise starch, sugar, oil and
fat. They irst make tEeir appearance
IN organized bodies. Sugar is found in
the economy and Is derived from starch,
which comes from potatoes, beans and
wheat. 1t also is found in the brain.
The ingredients sugar and starch are
az much essential as the others. The
oily and fatty Substances are found ia
nuts, butter and meats. Starch and |
sugar produce fat. Stout persons who
wish 10 become lean must abstain from |
the use Of sugar aud starch and fatty
food. When negroes and animals in
The South eat the contents Of the sugar
cane they become stout.
The third class, or organic sub.
tances, comprise hbrin, albumin, can-
cip, globulin. pepsine, pssereslin,
muscosin, osteir, cartilaiin and muacu-
line. They cannot be orystalljzed, are
changed by heat, and are not found ex-
cspt in the bodies Of living or recently
dead animals. They cause ferrnenta-
ticn and petriacatioD and represent
the blood.
In order to fatten hogs they must be
fed with fatty matter. A pig that is
fed upon beans which were cooked in
greasy dish water will fatten sooner
than pig which has been fed upon
beans which were cooked in clean
water. The reason that we can exist
by using milk is because 1t contains
nearly all the substance mentioned in
proximata principles. The difference
between the cows and woman's milk
is that the former contains oil and but
ter while the latter contains sugar, and
to make the former as good as tho lat
ter water and sugar will have to be
mixed in it.
The proportions of cows' milk are as
follows:
Water S7.2 per cent, case in 4.4S,
butter 3.13, sugar AIT, and other sub
stances such as soda, chloride of potas-
stun and sodium, lime magnesis, iron,
etc., go. Wheat flour is composed
of gluten, sugar, starch and non. nitro
genous substances, proportioned as fol-
lows: Gluten 7.30, starch IL, sugar
$40, gum 8 30, water y. The pro-
portions Of oat meal are: Starch So, bat
ter matter and sugar S.25, gray albu-
men 81, fatty oil 2, gum ESQ, and
husk and waste matter 1896. OF eggs,
the white is composed Of albumen and
salts, and oily matter in the yelk, pro-
portions as follows in the white: Water
SO, albumen 1928. salt 4.72; in the
yellow, water 1878, album men 1915,
yellow oil, 28.7J, and salt 4 ~. Flesh
or ordinary butchers meat is composed
of slbumen, muscular fibre and fatty
or adipose tissue, with the following
proportions: Meat $50 (of which
So. AZ is water and 22.2S solid), and
fatty matter IA 30.
The ordinary amount OF food needed
by a man during "a hours has been de-
termined by experiments OF Hammond,
Dalton and Flint OF New York. The
figures, as obtained from actual obser.
vation, are, meat 16 ouRces, bread 191
ounces, butter or oily matter ounces,
and water 81 ounces.
At the next lecture next Friday even
ing, Mr.. Mcdonnell will consider the di-
gestion and assimilation of food, the in.
fiuence of the use of tobacco and liquor,
how the tissues ara maintained and the
cause of dyspepsia.
