ROYAL POLYTECHNIC

INSTITUTION.

Dr. John Ryan, the chemical lecturer to the above insti-
tution, is now delivering a course of most interesting che-
mical lectures. On Monday last the Doctor delivered a lec-
ture on the principles of chemical analysis, and, although at
first eight, the subject seems to present insurmountable diffi-
culties to its adoption fur a popular auditory, yet, in the
hands of the talented lecturer, the illustrations became so
simplified as to bring it home to the understanding of the
youthful part of the audience. As Dr. Ryan invariably
endeavours to draw his facts from the great volume of
Nature, and makes his experiments bear upon the connexion
between science and the general concerns of life, however
complex tho subject, however scanty the materials, the
whole becomes in a short time invested with a powerful in-
terest. It is this circumstance, we have long been convinced,
that has raised Dr. Ryan so rapidly in public estimation.
We may mention as an illustration of the Professor's happy
manner of conveying important instruction at the chemical
lecture- table, the following fact mentioned by him on Monday
last:—Speaking of the peculiar laws influencing the dif-
fusion of the gases, the Doctor stated that our atmosphere
invariably contained three gases in a state of mere me-
chanical mixture, and although varying in specific gravity,
these bodies at all altitudes and at all seasons were found
mixed in the same precise proportions. One of these gases
is carbonic acid, given off during many natural processes, and
always forming the one two-thousandth part of our atmosphere.
This gas is so heavy, that 100 cubic inches weigh forty-
seven grains, while the same bulk of air weighs thirty-one
grains; therefore, if gases did not diffuse themselves equally,
we should have the heaviest body forming the lowest struc-
ture of the-atmosphere, and as carbonic acid is destructive to
life, existence in its present form would be impossible ; for at
the most moderate calculation we should have at least ten or
twelve feet of that air on the surface of the earth. To pro-
vide against this we have the laws of diffusion.

THE CAMBRIDGE AND OXFORD ROWING MATCH.-
shortly after eleven o'clock, the
This race came off this morning
boats starting from Mortlake, and rowing down the river to Putney-
bridge, when, after a very severe struggle, the Cambridge crew were
declared the winners, having beaten their opponents about three
boats' length.

DEPARTURE OF TROOPS FOR INDIA.—This day, about
one o'clock, a detachment of troops, en route for Woolwich, preparatory
to embarkation'for India. marched down the Kent-road, headed by their
band. The road was crowded by persons who seemed to take great
interest in the brave fellows, and we think it not improbable that
' many "a tall fellow" was stimulated by their example to enter her
Majesty's service, for a recruiting party, which was at hand,ihad a
long train of followers with gay ribbons in their hats.
VACANCIES IN THE CUSTOMS' DEPARTMENT.—Within
the last few days upwards of twenty lockers, twenty weighers, and
several tide waiters, have• been called upon to retire from the service,
previous to being superannuated on pensions. Many of these men
have been ir. the revenue service for thirty years. The vacant
situations are at the disposal of the Lords of the Treasury.
MAlZE.—Arnongt the uses to which maize may be
put, is that of feeding poultry. The poultry of Toulouse is remark-
able for its delicacy of flavour, and its texture of flesh and fat; it is
fattened on maize. A person accustomed to fowls so fad can easily
distinguish them in the market from any that may have bean fat-
tened on other kinds of corn. So also maize is esteemed in the south
of France the best food for fattening pigs, insomuch that in pai-t..
'Where maze is dearer than barley, still maize is purchased to finish
the fattening of a pig.

CITY, QUARTER TO THREE.
The Cotton market at Liverpool yesterday was rather
quieter, but prices were steady. Sales about 5,000 bags,
500 of which were American and taken by exporters. Shares
were dull and prices lower.
Thanks to the perseverance of the Committee of Spanish
American bondholders, the foreign creditors of Mexico have
had full justice done to them at the hands of the Messrs.
Lizardi and Co., the former financial agents of the Govern-
ment of the Republic. There have bet rt remitted, as all our
readers, especially those more immediately interested know,
stuns equal to about 65,0001. for the dividends on Mexican
Stock, but which for a long time past have been hermetically
sealed up by the Lizardi's and Co. A Chancery process has
compelled those parties to come to terms, and bills at various
dates extending over a period of 18 months have been ac-
cepted by the firm just mentioned in favour of Messrs.
Schnieder and Co., who are now the financial agents of the
Mexican Government. We cannot help observing that the
Committee of Spanish American Bondholders, of which Mr.
S. R. Robinson is the most active chairman (and if our re-
collection serves us, for a period of not far short of twenty
years), have a claim upon the bondholders of all the South
American States for something more than empty pra'se, for
their zealous advocacy of the rights of the foreign creditors
of the States of South America, all of whom have had to be
driven into a course of honest policy. At the next general
meeting of South American Bondholders, we trust to see
some right• minded creditor of the Republics propose
that the exertions of the Committee, crowned with success
as they have been in the cases of Mexico and of Chili espe-
cially, should be not only virtually acknowledged, but that
something more substantial should be awarded.
The English Stocks are at present very quiet, and there is
scarcely any fluctuation in prices. Consols have been 961%
to 96% for money and time. The premium on Exchequer-
bills has been up to 295. and is now 265.
The Foreign Investments have been dull, and there is no
speculation except in Mexican Stock, which has been rather
lower, viz ,32 to 313 for the Actives. Portuguese Con-
verted Three per Cents. have been 58%; and the Four per
Cents., 57. Dutch Two-and-a-Half per Cents. have been
marked 59%; and the Four per Cents., 92 to 92% ex-div.
Aust.' ian Bonds are IL3.
For Railway Shares the demand is slack, but there is
every hope now of an extensive winding up of the different
schemes, and the prosecution alone of those most imperatively
needed, for this would give stability to prices generally.
