respiration, mostly extracted from Huxley's "Elementary Lessons in
Physiology," and therefore excellent in its way, though having a
somewhat remote bearing upon the subject as announced in the title of
the article. We trust that before this journal concludes its series of
articles thus commenced, it will tell how to breathe into the breasts
of the corporations which choke us in their human packing boxes,
something resembling the soul which they are universally acknowledged
to be destitute of. When this is done, carbonic acid, ammoniacal
smells, organic exhalations, smoke, and dust, will be invited to shun
the interiors of railway cars, and comparative comfort will descend
upon the peregrinating public.

THE MINERAL RESOURCES OF MISSOURI.

The incalculable wealth, which lies hid in the bosom of Mother Earth,
in our vast possessions of the West, is undoubtedly centered in the
State of Missouri; and the development of this fund of riches must
add to the national prosperity, not only by its immeasurable intrinsic
value, but by its affording occupation to armies of laborers, the
latter being the highest and most important consideration.

In 1852-3, a geological survey of the State was wisely decided upon,
and a liberal provision for its execution made. Two valuable reports,
by Professor Swallow, have been printed, in the year 1855, but the
notes of his subsequent investigations have not been made public.

In the session of 1869-70, further action, in this important public
work, was taken by the State legislature, and arrangements made for a
still more accurate and detailed examination, under the direction of
Professor A. D. Hager, of Vermont.

The distribution of metals all over the State will be seen in the
following figures, taken from the St. Louis _Journal of Commerce_,
which show the number of counties in which the various ores are found:
Iron in 46 counties, lead in 43, coal in 36, copper in 24, marble in
11, zinc in 27, fire clay in 16, barytes in 10, nickel in 6, granite
in 4, tin in 4, plumbago in 2, gypsum in 2, alum in 1, antimony in 4.

There is probably no country in the world so endowed as this. Of iron
alone, according to the State geologist's report for 1855, there is
ore of the best quality, sufficient to furnish 200,000,000 tuns of
iron; and this quantity lies in a small space, in the vicinity of
Pilot Knob and Iron Mountain, and within 100 miles of S
