many respects the most interesting one of the kind yet examined.
Mounds of this class received from Squier and Davis much less
attention than the smaller “ Alter Mounds,” as the latter usually
contain more relics of ancient art. ‘These authors, moreover,
examined none of those belonging to the Mewirk group of
works, although the mounds in that vicinity appear to present

selected for examination was about two and a half miles south
of Newark, on the farm of Mr. Thomas Taylor, and was known
in the neighborhood as the “Taylor Mound.” It was conical in
form, about ten feet in height, and eighty in diameter at the

mounds in that vicinity. It was situated on the summit of a
ridge, in the midst of a stately forest. On the mound itself

fossil shells, apparently Cretaceous species. No rock of precisely :
this kind is known to exist in Ohio. Pieces of a tube of the ~

the pipe. The cavity was about two-thirds of an inch in diam-

tubes have occasionally been found in mounds, but their use is
not oC known.

of several square yards, Near the center of this — =

About a foot below the remains just described, and a little
east of the center of the mound, were two adult human skele-
tons, lying one above the other, and remarkably well preserved.
The interment had evidently been performed with great care.
The heads were toward the east, slightly higher than the feet,

and the arms were carefully composed at the sides. A white
ort similar in every respect to the one already mentioned,
was here voy distinct, and extended horizontally over a space
of five or six yards, in the center of which the remains had
been laid. The earth separated readily through this stratum,
and an examination of the exposed surfaces showed that they

decomposition of the inner layers had produced the peculiar
white substance, as a subsequent microscopic examination werk
indicated.* Directly above these skeletons was a layer of r

for some time, and then tie to go out; when the Seaman
of bone and cinders that remained were scraped together, and
covered with earth. All the bones were in small pieces, and

the lower extremity of a humerus, and some fragments of a
fibula, which showed them to be human, and indicated an adult
rather mee “~ medium size. The two skeletons found beneath
thes ue ere well formed, and of opposite sex. The

thirty years of age, and the male somewhat older. It is not im-

charred bones may have been those of a human Gporites slain
at the funeral ceremonies.’ Near these skeletons was a sma
quantity of reddish brown powder, which proved on examina
tion to be hematite. It was probably used as a paint.’

On continuing our excavations about a Pi joer Ted some-
what more to the eastward, a second pile of charred human
bones was found resting on ala ayer of ashes, charcoal and burned

clay. But one or two fragments of these remains could be
identified as human, and these also indicated a small-sized adult.
The incremation had apparently been performed in the same

older. In this case also the head was toward the east, and the
burial had been carefully performed. Near this skeleton about
a pint of white chaff was found, which appeared to belong to
some of the native grasses. The form was still quite distinct,
although nearly all the organic substance had disappeared, A
few inches deeper, near the surface of the natural earth, several
skeletons of various ages were met with, which had evidently

een buried in a hurried manner. All were nearly or quite
horizontal, but no ot of bark had been spread for their recep-
tion, and no care taken in regard to arrangement of limbs, These
skeletons were in a tolerable state of preservation, some parts
being quite perfect. A tibia and fibula, with most of the cor-
responding bones of a foot, were found quite by themselves, and
well preserved.

Our excavations had now eee the 5S pte surface of the
ridge, on which the mound was erected, and we were about to
discontinue further researches, me the dark ior of the earth

had evidently been thrown in carelessly,—most of them soon
after death, but one or two not until the bones had become de-
tached and weathered. Some of the bones were very well pre-
J ved, and indicated individuals of various ages. T'wo infants,

t a year and eighteen months old respectively, were each

represented by a single os illium, and bones o ral

which had been gnawed by some carnivorous animal. Th
marks of the teeth were sharply defined, and corresponded to

Quite a number of implements of various kinds were found
with the human remains in this grave. Near its eastern end,
where the detached bones had been buried, were nine lance and

crops out a few miles distant. These weapons are of “peculiar

ponded steaely in form with the stone hand-axe figured by
Squier and Davis as the only one then known from the: mounds.®
With these axes were found a small hatchet of hematite, a flint

already alluded to, were a large number of bone implements, all
exceedingly well preserved, Among these were five needles, or

the metatarsal bones of the common deer; and also a pcm:

doubtless due in part to the excessive compactness of the earth
above the remains, but mainly to the fact that the mound stood
on an elevation, where moisture could not accumulate. The
skeletons in the lower part of the mound were not so well pre-

very long duration, as no perceptible deposit of vegetable matter
was formed over the small mound then existing. The same
may be said of the intervals between the regular interments,
and also of the subsequent period preceding the final completion
of the mound. It should, perhaps, be remarked before proceed-

the ancient Egyptians, and the Danes of the stone age, did not,
in eating, use the incisive teeth for cutting, as modern nations
do. This is evident from the fact that the worn incisors are all
truncated in the same plane with the coronal surfaces of the
molars, showing that the upper front teeth impinge directly on
the summits of those below, instead of lapping over them. This

particular case a rate of infant mortality (about thirty-three per

cent) which is much higher than some have supposed ever ex-
isted among rude nations. Another point of special interest in
this mound is the evidence it affords that the regular method of
burial among the mound-builders was sometimes omitted, and
the remains interred in a hurried and careless manner. This

was the case with eleven of the skeletons exhumed in the course
of our explorations, a remarkable fact, which appears to be
without a precedent in the experience of previous investigators.
It should be mentioned in this connection that nearly all of
these remains were those of women and children. Their hur-
ried and careless burial might seem to indicate a want of respect
on the part of their surviving friends, were there not ample evi-
dence to prove that reverence for the dead was a prominent
characteristic of the mound-builders. It is not unlikely that in
this instance some unusual cause, such as poms or war, may

deserve notice, as they far —— in number = variety any

that, if in this instance the rites of. regular burial were denied

ing age of. weapons, which were found with these detached

ould seem to imply that in this case the remains and
sl ‘of a hunter or warrior of disctinction, recovered after
long exposure, had been buried together.”

The last three interments in this mound were performed with
great care, as already stated, and in strict accordance with the
usual custom of the mound-builders. The onl int of par-
ticular interest in regard to them is the connection which ap-

ars to exist between some of the skeletons and the charred

uman bones found above them. Similar deposits of partially
burned bones, supposed to be human, have in one or two in-
stances been observed on the altars of sacrificial mounds, and
occasionally in mounds devoted to sepulture, but their connec-
tion with the human remains buried in the latter, if indeed any

existed, appears to have been overlooked. Our ex xplorations,
which were yey ae and systematically conducted, clearly
demonstrated that in these instances the incremation had taken

place directly oe "thé tomb, and evidently before the regular
interment was completed: taking these facts in connection with
what the researches of other investigators have made known

A similar custom still prevails among some tribes of western Indians,

better, of a compound plate of the’ same metals, the juncture
being soldered, as when plutes are used, the couple suffers but
little i injury from the repeated falls of the ball. In the selection
of these two metals for the couple, a suggestion of Poggendorff
is followed, who showed that they give a strong current when
their juncture is heated. The couple is so arranged that the
ball strikes just on the juncture of the two metals, and there by
means of the heat developed, produces a thermo: electric current.
The juncture of the two metals was generally insulated by silk,

The two farther ends of the couple were fastened. by bos bind-
ing screws ss, which were in metallic connection with a delicate

Below the eenegae is the brass anvil A.

A certain amount of heat is developed at the junction of the
couple by a given fall of the ball; if now the couple were left
in contact with the ball and anvil after the fall, this heat would
be rapidly conducted away; it therefore became e necessary to
contrive, first, an apparatus for raising the ball instantly after
its fall out of contact with the couple, and second, some arrange-
ment for raising the couple at the same instant out of contact
with the anvil. The ea of these ends is accomplished by
the lever L, the shorter arm of which is cut out so that when it

quickly pressed down, and fastened by turning the bent 4

and the latter itself acting at the same instant as a spring,
raises itself by its own elasticity above the anvil. The wires

The upper needle of the galvanometer was provided with a
very fine glass rod, which served as an index, the breadth of the
rod being only half of that of the divisions on the galvanome-
ter circle. The end of the glass rod was blackened to render it
plainly visible. Directly over the needle, a mirror silvered by
Liebig’s process was placed at an angle of 45°; the index was
observed with aid of this mirror and a small telescope magnify-
ing five diameters; in this manner ,;';° could be est d

If these precautions are neglected accidental currents are con-

to remain at rest for two or three hours, so that the currents

The galvanometer was made by Duboseq; after balancing the
magnetism of the needles it was found that the copper wire of
the coil was so magnetic that the needles took up a position 30°—
85° on either side of the zero point. I re-wound the frame
with American wire, when the needle readily returned to the
true zero; upon, however, bringing the two needles very nearly
into the same plane, and carrying forward their astasie, the same
difficulty was again experienced, when another sample of Amer-
ican wire was tried with a result which was but little better.

All of these samples when tested in the apparatus used for
experiments on diamagnetism, were evidently magnetic, the
French sample being strongly so. The difficulty was “evaded by
bending the needles slightly out of the true plane, when they
took up a position nearly east and west, and returned with cer-
tainty to the true zero. In this state of inferior sensitiveness
one simple oscillation consumed 18 seconds. There were suf:
ficient indications to show that owing to the magnetism of the
coil the needle was more sensitive to currents sam seem oe at
10°-15° than when at 0°; it accordingly becam ry to
calibrate the instrument with care. This was rer by one of
the methods described by Melloni and quoted by Tyndall, (Heat

considered as a mode of motion, p. 870).

For degrees under 10° the constant currents employed in the’

calibration were produced by a small thermo-electric pile with
one of its faces turned toward the exterior colder wall of the
room, while the other face was directed toward an interior

These, as it were natural sources of heat gave very constant
currents, and by partially closing one of the caps of the pile,
any desired deviation between 0° and 10° could readily be ob-
taine

It was found that for about 6° the deviation of the needle
was directly pit tape to the strength of the current; for de-
grees beyond this, it was necessary to construct a curve em ye
ing the wher obtained experimentally. The ratio between
the first and final deviation up to 30° was also obtained ; it was
constant for 6°. These latter determinations were important,
as after the first deviation the needle, owing to conduction in
the couple, slowly sinks to 0°, and only then comes to rest. I
was not able to measure with exactitude the time required for
currents produced by falls of the ball from different distances to
subside, the imperfect results obtained showed that it varied be-
tween ik minutes up to 84 minutes, according to the distance
fallen by the ball. 1t having been found then in the calibration
experiments, that the force of the current was proportional to
the deviation up to 6°, and farther, that the first deviation was
proportional to the final deviation for the same number of de-
grees, in the results given below, where the first deviation was
peor eS the observations actually obtained and unreduced will

n, but where the first deviation exceeded 6° the reduced

ate will be found.

As the total amount of heat produced by the fall of a body
is divided between the falling body and that arresting its motion,
it is evident that if the mass of the latter be small compared
with that of the falling body, its temperature will, owing to this
fact, be correspondingly high; and if the siete body be a
thermo-electric element of small mass, a proportionately large
deviation of the galvanometer needle will be produced. Te
however, the couple at the moment of the percussion and after-

wards, be allowed to be in metalli@ contact with the metallic
ball, the temperature of the couple will by conduction be rapidly
reduced to that of the metallic ball, so that the deviation of the
needle will be very small, and the phenomena complicated. T
illustrate this I give, in table 1, the small and irregular devia-
tions which were produced v under these circumstances

that the plate had not been altered, experiments were made:
with it afterward, the ball being lifted.

To find out whether any peculiar influence was exercised by
the mass of the couple within small limits, the above mentioned
plate was now cut down, till its breadth was 3 millimeters. It
was covered with waxed silk and the following results obtained:

A pcan action was observed with unwaxed silk, This
might be accounted for by saying that the mass of silk and wax
becoming compacted is then a better conductor of heat than be-
fore, and that the temperature of the couple is thus lowered by
the short but necessary contact with the ball; but the compara-
tively small effect which is produced even by continued contact
with the ball shown in tables 6 and 8 prove that this supposition
is untenable.

The larger deviation must then be attributed to the sliding of
the particles of silk and wax over themselves, this taking place
to a much greater extent in the first twenty falls than afterward.
After the minimum point has been reached, if the couple is laid
bare and rewound, the same large deviations are obtained, show-
ing that they are not due to an alteration in the couple itself.

Finally, it is remarkable that a much smaller mechanical force
m3 lied directly to the couple in the shape of friction, produces
isproportionately large deviation ; thus drawing the wooden
pie of a lead-pencil once over the naked junction with a force
less than would be ee iy the ball falling 1 inch gave a
deviation of 18-25°

It is hardly necessary to add, that the deviation of the needle
was in all cases in the same direction as though heat had been
applied to the juncture of the thermo-electric couple

It is not enough to call them soft bodied animals; for in consid-
ering their shell as a part of their organization, we have among
them many of the hardest animals known, and we also have an

number of soft bodied animals in the other branches.
Their bilaterality, as cieiing anything definite, is an equally
unsatisfactory character. Prof. Huxley has given an archetype,
or common plan of the Mollusca, as he conceives it, with many

Though Prof. Agassiz speaks of ie regs i - characterizing
the Radiates, and similarly of articulation and vertebration as
characterizing the Articulates and Vertebrates, yet Mollusks are
spoken of as first introducing the character ‘of bilaterality, or
division of parts along a longitudinal axis, that prevails through-
out the Animal Kingdom, with the exception of the Radiates,
This then can be no restricted definition for the Mollusca, since
it pervades the two higher branches; and who will deny the
evidence of bilaterality among the Radiates, the higher Hchino-
derms for instance, as Clypeastroids and Spatangoids, where we
have as good a definition of a longitudinal axis as we obtain in
many Mollusks. Even among the Polyps, as in the Actinaria,
the antero- — axis is eepaeed expressed in the undue prom-
inence of the primary rad.

Prof. Dana se been the first to publicly announce the plan
of Mollusca, when he says, “The structure essentially a soft,
fleshy bag, containing the stomach and viscera, without a radiate
structure, and without articulations,’

As far back as 1855 he presented this thought in his lectures

In the year 1862 Mr. Alpheus Hyatt had independently
worked out a similar result, and has ase in MSS. notes, the

certainly worthy of consideration, as it so clearly indicates what
can believed to be the fundamental ‘idea i in the Branch, that of the

essential structure of the animal, if rightly understood, must be
our guide. The gradual morphological changes of the contents
of the sac, and all other relations, are based on the principle of
Cephalization. In the plate presented (Series J) I have given a
typical figure of the six prominent groups of the Saccata;
namely, Polyzoa, Brachiopoda, Tuni nicata, Lamellibranchiata,
teropoda, and Cephalopoda.

apparently governed by no law, we can yet trace be sity tines
movements toward a normal condition, by comparing Appendi-
cularia, one of the lowest forms of the ieee ae repre-
senting the larval condition of their class. In this form the
intestine has a ventral flexure, and terminates on the ventral
side. In Pyrosoma it makes an abrupt bend toward the anterior
dorsal region, and terminates anteriorly. In Salpa it terminates
dorsally, on a line with the mouth, though still anteriorly.
Botryllus it creeps up, and terminates nearer _ posterior pole
of the sac, though still dorsally. We have in this genus, and
other compound Ascidians, the excurrent oie of several in-
—o coalescing, forming a common cloaca for a community.

e dorsal flexure is oe seen in Giayalliva borealis. In
these rear classes; namely, Polyzoa, Brachiopoda, and Tuni-
cata, the sac is essentially closed at the anterior end, and conse-
quently the mouth opens toward the posterior end, and with
few exceptions all are attached by the anterior en

This makes a natural division, corresponding to the Mollus-
coidea of Milne-Edwards, the Anthoid Mollusks of Dana, and a
portion of the neural division of Hux xley. In the Lamelli-
branchiata — I, L) we have the sac opening anteriorly,

d the mo permanently occupying the anterior region,
though in ha seni forms pointing posteriorly, and in all cases
the tentacular lobes pointing in that direction, and the mouth
bent downward (ventrally), and partially obstructed by the
anterior adductor, or by the undivided mantle. The gradual
ry of the eae poset is clearly seen, rea in

highest class, all this display of structure lies at the anterior
pole. Advancing from the Polyzoa, by the gradual advance of ©
the mouth, the posterior pole becomes less prominent. ve
when the sac opens anteriorly, as in the Lamellibranchiat.

24 E. 8. Morse—Classification of Mollusca

the posterior end of the sac remains open, and the mouth, par- —
tially inclined that way, receives its food from that end; the
food being conducted to the mouth by ciliary motion as in the
three lower classes. The nature of their food is also identical,
being of an infusorial character, and as such it is obvious that
masticating organs, or biting plates, such as we find in the two
higher classes, are not needed.

So long also as the posterior end of the sac remains open, the
anus terminates at that end; when this opening becomes closed, }
as in the higher classes, the anus seeks an outlet through the
anterior opening, and the mouth, that before received its food |
from the posterior end of the sac and by ciliary motion, now
distinctly points the opposite way, and is furnished with the
proper organs to procure food, the nature of which requires
separation and trituration '

in which I place the Tunicate sac, I am sustained by heat rit-
ings of eminent naturalists. With the a le poeever,

hierdeeiiay whether it be by a byssus, confined in cells of their
own making, or buried in the mud, it is the anterior end which
is fixed. In several lower forms, ‘like Tridacna and An nomia,
the point of attachment springs from the doe area, as in the
two lowest classes. In regard to the posterior position of the
mouth in Polyzoa and Brachiopoda, we have similar analogies
among the Articulata ; aioe cre for example, where we have
animals ae attached head downward, and all the ont
arts, as in the pedunculated forms, tending toward the pos-
terior pele: of the body; or in Li mulus, where we have such a
decephalization, as it were, that the mouth occupies nearly a cen-
tral position in the ve entral region.

Again, considering the intestine as a simple tube, opening at
each end, with the weight of structure evenly divided between
the two openings, is it any more incredulous, that the oral open:
ing should be a than that the anal ‘opening should be
anterior, as in the

In Polyzoa, the ee and anal openings occupy a similar posi-
tion in all the forms. In Brachiopods, while the mouth remains
in nearly a constant position, the anus terminates either in a

median line, or by a lateral deflection of intestine to one side.
In Tunicata, while the mouth i se a permanent position at
the front of the sac, the anus terminates at various portions of
the sac, generally in a a nm though there is usually a
lateral Seite of the intestine.

In Lamellibranchiata, nie eee and anus terminate in a me-
dian line, with few exceptions, (e.g. Pecten) though the intes-
tine convolutes in various ways. In Gasteropods we have again
lateral deflection of intestine, and though in many sige the
anus terminates in a median line, yet in the bulk of the Gaster-

opods it terminates at one side or the other. In the Dibranchi«

The Monomyarians combine in their structure both high ="
low characters. In their open mantle, and certain other features,
they rank high. In their fixed position, the attachment gener-

would indicate the presence of both anterior and posterior ad-
ductors, combined in consequence of the excessive shortness of
their antero-posterior diameter. The Monoyarians present sin-
gular features of xoialeery with the Prachicwiodk. Thus they are
generally inequivalve. The viscera are compacted toward the
dorsal region, and, when attached, they are generally by a pro-
cess from the dorsal portion (e. g. Ano mia), the lowest feature of
attachment. In all these instances; particularly with Anomia,
the analogy is very striking; it is analogy only, and nothing

more, for in their whole structure, and in the relative propor-
tion of their diameters, they present just the opposite extreme.
While we have in Brachiopoda the growth laterally, that is,
spreading on the sides and depressed dorsally, and the valves,
dorsal and cahkiad, in the Monomyarians we have the other
extreme; the valves are right and left, and the display is hi
the side, ‘the growth extending ventrally as it were. Sona
are they that in certain forms, Placuna for example, it is Seok
impossible to conceive the presence of soft parts between the
valves. We compare the relative diameters between the Brach-
iopods and Monomyarians, to show how unlike they are in this
respect.

end downward. In Calyptrasn they are in a fixed position,
pecreting a ine valve, upon which they rest. It would be
interesting to know for a certainty which part first becomes
attached in Vermetus and allied forms; their, first point of
attachment must take place at the mouth of the tube or a aper-
ture, which is really anterior and ventral. The Cephalopods
are free.

Thus we have the various regions of attachment, changing
and wel in the diencsion indicated by the arrow A, in

cend in structure toward the anterior end, so we find the princi-
pal organ of locomotion, i.e., the foot, is first developed from
the ventral region, and in like manner tending toward the ante-
rior end, as we ascend in the scale, until, in Cephalopoda, =
ed divisions of the foot surround the head, and poin

aving personally communicated the substance of this paper
to Professor James D. Dana, he has, in a letter to me, indicated
certain gradient ieleaon: among the Lamellibranchs, Gastero-
pods, and Cephalopods, as manifested in the special characteris-
tics of the — or anterior part of the body, so clearly illus-
trating the principle of cephalization that I now take the liberty
of presenting them. In the Lamellibranchs the foot is a simple
muscular organ developed from the ventral surface and protrud-
ing anteriorly. It is simply an organ of locomotion, in the
lower forms not even performing this faneliote The oral open-

We have based the preceding considerations on the common
structure of each class, and for comparison have given an arche-
type, as it were, of each class ‘Cane I). In continuing these
archetypal figures, as illustrating the relative diameters and
mean forms for each class (Series I and IIT), and also the mean,
or average position in nature of the antero-posterior axis (Series
IV), we obtain singular features of polarity,* which I will now

tentacles surround the mouth only; the anus terminating out-
side the lophophore. Witness in the highest order of Cephalo-

s, the Dibranchiates, the sae as in Loligo (Series I, C), long
and cylindrical, and in all cases mouth and anus opening ante-
riorly; the arms surrounding the mouth only. Two rough
diagrams, alike in form, but reversed in one case, would repre-
sent each class as we have it here. In Brachiopoda (Series U,

, L) the same. The relative diameters of the Monomyarians
are unlike those of any other class, as before pointed out.

It is confidently believed that when these relations or polari-
ties, between the ascending and descending, or, as Professor
Dana terms them, the Holozoic and Phytozoic classes, have been
further studied, new and interesting features will be revealed.
Thus, the resemblances between the Tunicates and Lamelli-
branchiates are too obvious to indicate.

Among the Brachiopods and Gasteropods, beside what has
been pointed out, we have unlooked for similarities, as for
instance Discina and Calyptraa, or Terebratula and Hyalea.
Among the Polyzoa and Cephalopoda, though no polarities are
brought to mind, except those given above, yet we cannot help
remarking how strong the resemblance is between the Polyzoa
and Protozoa, through Vorticella: and if Vorticella belongs to

Polyzoa, as Professor Agassiz appears inclined to believe, a few
steps more bring us to the Ammonitic forms of the Rhizopods.
This is speculative (though suggestive), as it is now considered
by many that the Protozoa forms a fifth Sub-Kingdom.

considering transverse sections of the sacs, as shown in
Series III, we obtain a like order of polarity. Thus the highest
orders in Polyzoa and Cephalopoda presents a circular section.
Brachiopoda and Gasteropoda are transversely oval; Tunicates
and Lamellibranchiates are longitudinally oval, or in lower
forms circular; while the Monomyarians have the dorso-ventral
diameter in excess, and the transverse diameter reduced to the
minimum.

In considering the position, or angle of the antero-posterior
axis of each class in nature, we obtain similar results (Series IV).

Polyzoa and Cephalopoda, we place in a horizontal position,

ing a swimming Dibranchiate for comparison: this may be
premature however.

the Monomyarian horizo zontal again. It must be remembered
that the above considerations are pci in their most general
sense, representing only the mean for each group, many of them
erhaps erroneous. They are given rather for the purpose of
indicating a further path of inquiry, which the writer considers
fruitful and intends to follow, than as woe in any way settled.

In ascertaining the mean position of the antero-posterior axis
for the whole branch of Saceata, (that is, the average) we find
that a line at an angle of 45° would represent its position in
nature; the lower end being anterior. In the Radiates a line
through the mouth to the opposite region of the body would
stand ee In Articulates the antero-posterior axis would
be horizontal. Among the Vertebrates, Fishes would be hori-
gotta, = in Articulates ; Se ora have the head slightly ele-
vated; Birds and Mamm mals still more elevated; so that a mean
line, for ests classes might be drawn at an angle of 45°, the
cephalic region being uppermost. Man stands vertical. Thus
in a diagram we would have the following:

it expressed so simply as in the Mollusea; the leading idea as it

Art. IV.—Petroleum in tts Geological Relations; by Prof. E. B.
ANDREWS, Marietta, Ohio

N the number of this Journal for July, 1861, I gave some
facts bearing ea the geological relations of petroleum. My
attention at that time was confined chiefly to those locations
found in the Coal-measures of West Virginia a Southern Ohio.
It is gratifying to know that the views presented in that paper
have since been fully verified. As predicted, by far the larger
part of the oil produced has been found along the axis of a well-
marked anticlinal, extending from the borders of southern Ohio,
forty miles or more, into West Virginia, through Wood, Ritchie

and Wirt counties. A smaller quantity has been found in the
tolinca rocks of Ohio; while scarcely a barrel has been ob-
tained in horizontal rocks, although hundreds of thousands of

generation of oil have existed over a wide area; but the physical
condition of fissures is found to exist in comparatively iat
reas. Fissures serve two purposes, one to give space for the
formation and expansion of the hydro-carbon vapors, and th
other to furnish receptacles for the oil when condensed.
ures must connect with the deeply seated sources of ot oil

ence, while, as a general rule, oil found near the surface is
heavy, the fissures sistant it being more likely to have sur-
face outlets, yet sometimes the ver y deep fissures may have such
outlets, and the contained oil be heavy.

e West Virginia oil field presents many points of great sci-
entific interest. All the seodlicaua oil wells in this part of the
State group themselves along the anticlinal line marked out in
the article referred to, this line being the one of the greatest
fissuring of the roc cks. Toward its northern and southern ex-
tremities this line presents the form of a simple anticlinal with
the rocks so a on either side of the axis at angles varying
from 5° to But in the middle part there is a double frac-

from 30° to 60°. Without having made any instrumental meas-
urements I have estimated the thickness of these strata at about
eight hundred feet. C gives the position of strata lying within
what is popularly called “ the break.” These rocks belong to
the Cae al-measures and have been more or less flexed by
lateral pressure. It is in these middle rocks that the most valu-
' able wells of West Men urs are now being obtained. Wells
bored in the rocks A, A, have been failures as also the wells
bored in B, B. The rocks B, B, appear to have been lifted up
bodily, and in such a way as s not to have been much fissured.
The advantages of the inner strata, marked C, as oil-producing
- rocks, are: first, they are bent and more or less fissured ; secon
they are many hundred feet lower in he series than the strata at
A, A, and are consequently so much nearer the equivalents of
the supposed sources of oil in the Dev Coan rocks of Western
Pennsylvania and Canada; and third, this local disturbance of
the rocks doubtless involves in its many fissures these underly-
ing Devonian strata, and thus has. given every opportunity for
the generation of oil and its upward ascent.

i by geologieally as the oil obtained in the upper Devonian
ocks of Venango Co., Pa. Thus far the oil obtained within

T cannot but regard the term “voleanic” as infelicitous when
applied to this region. Nothing is more sensitive to heat than
petroleum, and direct igneous action adequate to the work of
uplifting and dislocating the strata to this extent would, I think,
have driven off all the oil. The uplifted strata at C (fig. 2) con-

In this way alone could the sinking strata make room

selves. For the most part along the line there was a pretty
sharp anticlinal formed, but in the center of the line there were
two fractures which may, I think, be satisfactorily explained.
A popular illustration of the dislocation would be the case of
ice fractured and heaped up by the lateral pressure of currents.

the same time. The eae action along this line of uplift
must have been very great, as, in some places, not less than a
thousand feet of the jee -measures have been eroded. I can,
however, find no traces of any other agency of erosion than those
now at work, viz., atmospheric and aqueous. From West Vir-
ginia this line of disturbance passes into Ohio, crossing the Ohio
river near Newport, Messrs C03 OS but, farther to the

Little Muskingum river, is exactly in the anticlinal axis of one
of these smaller undulations. ‘This well began to flow in June,
1861, and is, I believe, still flowing. It is 200 feet dee

I have thus discussed the relation evidently existing between
lines of geological disturbance and the production of oil in West
Virginia and southern Ohio. <A similar connection has been

observed by Sir Wm. E. Logan in the oil fields of Canada (Ge-

ology of Canada, p. 379). The oil obtained on the upper Cum-
berland river in southern Kentucky has been found, so far as
can learn, in locations of similar disturbance.
But there is another and very important class of facts to be
noticed in connection with the subject of the geology of oil.
We find in many parts of the country a very marked tendency
in the oil to accumulate in certain geological horizons. The
stratigraphical position of most of the oil in southern Ohio (in
the Coal-measures) is in a vertical range of about two hun
feet of rocks lying. below the horizon of the Pomeroy coal seam
This is true in Meigs, Athens, Morgan, Noble and ashington
counties. There are some exceptions to this rule, but they are
On Big Sandy river in Kentucky, the conglomerate below
the coal is the “oil rock.’’ In Scioto and Pike counties in Ohio
there is a well marked horizon of oil springs in the Waverly
sandstone, within twenty feet of its line of junction with the
underlying black shale. At Mecca, in Trumbull Co., O., there
is a similar and well-defined “oil rock.” But the most notable
fact of this kind is observed in Venango Co., Penn., where, on
Oil creek, Cherry run, and Pit-hole, the oil is chiefly obtained
in the fissures of the “third sand-rock.” This rock’ is reached
at a depth of from eight hundred to a thousand feet below the
of the Coal-measures. Coal is mined in the hills adjacent
to Pit-hole creek. No oil, so far as I could learn when investi-
gating that region, has been obtained in the arenaceous shales

below the third sand-rock, although a few very deep oe

I would, in passing, venture to express my dissent from the
opinion of some egies, that oil which may have been formed
in higher strata descends to lower. In all my investigations of
this matter I have never found any evidences of such a fact,
while, on the other hand, the natural tendency of oil is upward:
the waters lift it up; its cognate gases often force it up; the
original oil vapors rise to condense in higher and cooler cavi-

lower fissures may often be re-volatilized, to ascend an

indefinite period. It is possible even, that in some localities all,
or nearly all, the oil has been bro ought up from its deep birth-
places to very near the surface. In such localities very deep
wells would avail nothing. It is certainly evident that on Oil
Creek, Pit-hole, &c., the oil has come from below. and aceumu-
lated in the fissures of the lower sand-rock. It could not have
been forced down from strata above. Confining the winds in

ags were an easy task compared with forcing down and shutting
up the oil with its furious gases in the cavities of the third sand-

moved under this cover to the northwest. These suppositions
are entirely untenable. The oil is found in independent fissures,
is

and combinations. Such facts forbid the supposition of great
lateral subterranean movements. The same reasoning would
apply to the theory sometimes published, that oil passes down
the long slopes of gradually descending strata to the lowest part
of synclinal basins, and there accumulates. Strong brine in an
open permeable rock ean thus descend, but not oil. If the brine
earried the oil down with it, we should expect to i in the
salt wells of Pomeroy, O., no little oil with the brine. The
brine there is obtained in the conglomerate a thousa te feet
down. When oil is obtained it is from fissures comparatively
near the surface.

speak with entire confidence. The whole region is covered
with drift materials hiding the seit rocks. There are

of bitumen, received from California twelve years ago, interested
me much as containing many very old bones. This specimen
prepared my mind to receive statements subsequently made,
that wild animals were sometimes mired and died in the tarry
oil springs in that State.
the origin of petroleum there are different opinions. All
agree, however, that it must ultimately be traced to vegetable
or animal substances, the primary combinations of hydrogen
and carbon being the product of vital force. It is the opinion
of Dr. J. 5. Newberry and others that petroleum in its present
form is the product of a slow distillation of bituminous strata.
From this theory Mr. T. S. Hunt of the Canada Survey, in the
“Geology of Canada,” p. 526, dissents, and quotes approvingly
the views of Mr. Wall, who investigated the bitumens of Trini-
ad, and who writes that the bitumen “has undergone a special
mineralization, producing a bituminous matter instead of coal
or lignite. This operation is not attributable to heat, nor of the
nature of a distillation, but is due to chemical reactions at the
ordinary temperature and under the normal conditions of cli-
mate.’ It would appear to be Mr. Hunt’s opinion that the bitu-
mens, of which petroleum is the liquid form, are the product of
chemical reactions changing the original organic materials di-
rectly into oil and kindred hydrocarbons. The facts cited in
proof are, that oil is found in the cavities of fossils (Orthocerata,
&c.), and in thin strata composed of certain corals, and in similar
cases, where the oil must have originated in the places where
found and directly from the organic materials. I have observed
many similar facts, particularly in the Devonian limestones of
Ohio. These facts are conclusive so far as they go. There is

42 E. B. Andrews on Petroleum in its Geological Relations.

In favor of the other theory, that petroleum, as now generally
found, is the product of a distillation of bituminous shales, &c.,
as suggested by Dr. Newberry and others, the following argu-
ments may be urged: Ist. Oil may be artificially produced by
distilling such shales and other bituminous materials. In all
essential respects, the analogy between the natural and artificial
oils is complete. 2d. The phenomena of oil and gas exhibited
in our oil fields greatly resemble those observed in the artificial
distillation of oil from bituminous materials, These phenomena
include inflammable gases, naphthas, heavy oils, asphaltums, &c.
3d. It is believed that some petroleum has been actually pro-
duced in the earth by distillation. Dr. Newberry, in an article
on ‘“ Rock Oils of Ohio,’’ thinks he finds local proof of the dis-
tillation of the petroleum in the great bituminous springs of
California, from Tertiary lignites, there being evidences of recent
igneous action in the region. European geologists have attrib-
uted a similar origin to the petroleums of Italy. Of course,
where igneous action is intense, all the bitumen would be en-
tirely driven off. The same would be true where the action is
considerable and long continued, as in the anthracite coal region
of Pennsylvania where the coal has lost its bitumen, but no oil
was formed, or, if formed, it was soon dissipated in gas. 4th.
There is an abundance of oil-making material in the earth.
The subterranean retort is largely charged. 5th. A compara-
tively low temperature is believed to be adequate to set free the
oil vapors. 6th. By this theory there might be produced an
almost indefinite quantity of petroleum, since bituminous strata
are found widely distributed. In this way the existence of pe-
troleum in so many different geographical districts may be
readily explained; whereas, by the opposing theory, we are not
certain that petroleum, as such, has been produced by the direct
bituminization of organic matter, except. in few strata and in
very insignificant quantity. Finally, the agency whigh would
volatilize the liquid bitumen, or petroleum formed by direct
bituminization, and bring it up and distribute it through the
_ oil horizons would certainly be adequate to distill the

ituminous shales, &c., and bring up the oil to the same ele-
vations.

It may, however, be objected, that if this theory of distilla-

The question, then, would be reduced to this, viz: do the bor-
ings in deep wells ever show that the deep bituminous strata
have lost any of their original and normal quantity of bitumen?

highest tides occur in December and January, and the lowest in

at Tahiti was, that the moon exerted less control over tidal movements
than in other latitudes or places in the Pacific Ocean, although simi-

more western gro

I was at the ca of Toubooai six days early in May of the
same year, during which J was making more or less observations
upon the reefs and shores, both on the northern and southern
sides of the island. The tides appeared to flow there with their
usual regularity, and rose to a greater height than at Tahiti.

I have been prompted to communicate these facts because I
have long considered oe tidal phenomena at Tahiti as important
to physical science as they are curious and anomalous; and

greatly enlarge our general cosmical knowledge, and establish a
more correct tidal theory than exists at ay oe notwithstanding
the high utility and value of that we now hav

ile upon this subject of tidal coments in the Pacific
Ocean, I will take occasion to mention that during a long period
of observation upon the coast of Peru with reference to earth-
uake phenomena, I found, not only the highest tides to prevail
at Callao and Paita in December and January, but also a series
of enormous waves or sea-swells to be thrown from time to time
upon the coast, varying from twenty-four to seventy hours in
continuance, accompanied by unusual heights of the tide during
the same period, and, on the contrary also, I remarked that the

earthquake phenomena, I have found them spoken of in the
past century, and that they lave often made ravages upon the

synchronism of periodic intensity of tidal movements,

as they have been observed on the shores of Tahiti and of Peru,
with the periodic intensity of earthquake and volcanic (plutonic)
movements throughout the surface of the entire planet, I have
been compelled to believe solar influence to be the predominating
element in causal action, and that the lunar connection with ter-
restrial phenomena is reactionary rather than direct. That the
periodicity and intensity of manifestation of internal dynamic
energy are connected with the position of the earth in its orbit,
holding inverse and constant numerical relations to the length
and sweep of the radius vector, as a general law, my observa-
tions and researches have established beyond contradiction or
doubt. And I have the strongest reasons to believe that sys-
tematic observations upon the oceanic movements at Tahiti and
other groups in the South Pacific, and upon the coasts of Peru
and Ecuador, will lead to the discovery of most important data
through which our present lunar theory will be greatly devel- :
oped, and probably profoundly modified. y

a nearly pure carbonate. A similar separation of the two bases
is obtained when dilute solutions of neutral carbonate are sub-
stituted for the bicarbonate of soda. These reactions are intel-
ligible when it is considered that hydrous carbonate of magnesia
at ordinary temperatures decomposes the soluble salts of lime
with the separation of carbonate of lime. . This is true not only
for the sulphate and chlorid, but also for the bicarbonate of
lime (§ 6).

77. It was further found that when such a solution contain-

evaporated at temperatures of from 80° to 70°C., the lime
was deposited as crystalline gypsum, mixed with more or less
carbonate, while the more soluble bicarbonate of magnesia was

Hydrated double carbonates of lime and magnesia,

81. The results noticed in the last section gave rise to further
inquiries into the affinity between the carbonates of lime and
magnesia, and to the discovery of some artificial hydrated com-
pounds of the two. The numerous hydrated double carbonates
studied by Deville were all compounds of the alkalies (potash
or — with magnesia or a magnesian oxyd. In his beautiful
memoir on these salts published in 1851 (An. Ch. et Phys, [3],
Xxxiii, 75-106), besides a series of double salts containing alka-
ine bicarbonatés with nine equivalents of water, Deville has

escribed numerous neutral double carbonates having the gen-
eral formula C,MMO,, which are either anhydrous or combined
with three, four, or ten atoms of water, HO; (H=1,C=6, O=8),

hydrated salts. A paste of magnesia alba and bicarbonate of
soda with water was found to be slowly changed at a tempera-
ture of from 60°-70° C. into transparent crystals of the anhy-
drous double carbonate, which crystallizes in the hexagon |
system and as remarked by Deville may be regarded asa soda-
dolomite C,NaMgO,. I have already shown, § 38-40, that
when this is heated to 200° C., with a solution of chlorid of
calcium, the sodium is replaced by calcium, and dolomite is
formed. It was with the anticipation that under conditions
similar to those made use of by Deville, it might be possible
to obtain double carbonates of lime and magnesia, that the fol-
lowing experiments, resulting in the production of hydrated .
carbonates, were undertaken. |

$82. The first step was to procure a solution of the chlorids
of calcium and magnesium in equivalent proportions, and for
this purpose a crystalline dolomite from Galt, in western Canada, .
whose only impurity was a few thousandths of carbonate of iron
was selected. This being dissolved in hot hydrochloric acid .
nearly to saturation, a little chlorine or chlorate of potash was
added, and the digestion continued with an excess of the dolo-
mite till the whole of the iron was precipitated, and a pure con-
centrated solution of the two chlorids in equivalent proportions
was obtained.

§ 83. When the above solution is mixed with a slight excess )
of a solution of pure monocarbonate of soda and the resulting 7
pasty mass heated to from 65° to 80° C., the precipitate is
wholly changed in a few hours into a dense white granular
matter, which, under the microscope, is seen to consist of pearly
translucent globules, either single or aggregated. They areusu- ~
ally about ,,',;th of an inch in diameter, and although most |
frequently spherical, sometimes present the form of disks hav-
ing a radiated structure and ragged edges. Lobed and com-
pound shapes from the coalescence of these disks are also met
with. This substance is so slowly attacked by cold dilute aceti¢
acid that it was at first mistaken by me for true dolomite, an
described as such in a note to the American Philosophical Society
before I had discovered water in its composition. It, however,
gives off an abundance of water when heated in a glass tube,
even after having been dried at 85°C. In the analysis of three
several preparations of this compound, in which the lime and
magnesia were calculated as neutral carbonates, there was always
a deficit of from seven to nine per cent, which was regarded as
altogether water. In a subsequent preparation, however, it was

found that when freed by washing from all trace of chlorids it
yielded a quantity of soda equal to 1:86 per cent of carbonate
of soda, and moreover that there was a deficiency in the amount
of carbonic acid, which was only about nine-tenths of that re-
quired to form neutral carbonates with the bases; so that the
compound isa slightly basic carbonate of lime and magnesia

nearly related to the native hydrodolomite or dolomite-sinter of

twelve days in one case, and twenty-five in another, pa

appeared to consist in the formation of nuclei, from which crys-
tallization proceeded until every particle of the once volumin-

from an excess of carbonate of soda, and held only traces of

of the mixed carbonates, and is transformed into small prisms
aggregated into spherical masses, like the double carbonates of
lime and magnesia. It is tolerably permanent in the air, and
yielded me 29:0 per cent of magnesia; which exactly corres-

chlorids favor the formation of unstable supersaturated solutions.

carbonates of lime and magnesia without any excess of carbonic

just cited. The power of alkaline chlorids and of chlorid of
calcium to prevent the precipitation of carbonate of lime, an

even to dissolve it when precipitated, has already been observed
by Berthollet and by Storer (Dictionary of Solubilities, 110),
but the inquiry does not appear to have been pursued farther.
In like manner the power of salts of potash, soda or magnesia to
prevent the precipitation of magnesia by alkaline carbonates, was
noticed by H. Rose and by Longchamp (Gmelin’s Handbook, iii,
225). These reactions | have made the subject of careful ex-
periments, one object of which was to determine whether hy-
drated or anhydrous double carbonates of lime and magnesia

of calcium are first mingled, is immediately dissolved by a solu-
tion of sulphate of magnesia, and by operating with solutions
of known strength, as indicated above, it is easy to obtain trans-
parent liquids holding in a liter, besides three or four hundredths
of hydrated sulphate of magnesia, 08 gr. and even 1-2 gr. of
carbonate of lime, together with 1:0 gr. of carbonate of magne-
sia, the only other substance present in the water being the chlo-

§95. I have found that monocarbonate of magnesia is still
more soluble than monocarbonate of lime under the conditions
described, and have in this way obtained more than 5:0 gr. of

six per cent of hydrated sulphate of magnesia and a little chlo-
rid of sodium. ‘This solution, strongly alkaline in its reactions, »

sia retains a portion of carbonate of magnesia even after the so-
lution has been long boiled, or evaporated to dryness; this is
manifested by an alkaline reaction and by the power of precipi-
tating the nitrates of silver and copper. That these reactions
are due to dissolved carbonate, and not to a sulphate with excess
of base, is indicated from the fact that the addition of small
quantities of hydrate of soda to a solution of sulphate of mag-
nesia gives rise to a precipitate of hydrate of magnesia which 1s
insoluble in the sulphate, and does not communicate to it an
alkaline reaction,

On the supposed decomposition of gypsum by dolomite,

§96. Haidinger, according to Bischof, has endeavored to ex-
plain the origin of the sulphate of magnesia observed in many
gypsum quarries by supposing a decomposition of the sulphate
of lime by dolomite, and Suckow has also proposed the same
explanation to account for an efflorescence of Epsom salt near
Jena (Chem. Geology, i, 430, iii, 159). Bischof mentions in
connection with the latter instance an observation of Mitscher-
lich, which from the omission of a few words in the English
translation, seems to imply that this chemist had observed the
complete decomposition of bitter-spar by a solution of gypsum.
On reference to the German edition, however, it appears that Mit-
scherlich had observed the decomposition of carbonate of mag-
nesia by gypsum, and thus that his experiments do not confirm
the hypothesis of Haidinger and Suckow, which we have here
to examine. It is therefore by an error that in my recent essay
on Natural Waters, § 19-21, I have attributed the views of
these geologists to Mitscherlich, whose original memoir cited by
Bischof is not accessible to me.

$97. In the paper just cited I have recorded the following
experiments: A solution of gypsum was made to percolate
slowly through a column of several inches of finely powdered
dolomite previously washed with pure water. After ten suc-
cessive filtrations of the liquid, occupying as many days, no per-
ceptible amount of sulphate of magnesia was formed. Solutions
of gypsum, and others of chlorid of calcium, were then digested
for several months at the ordinary temperature with pulverized
dolomite, and also with native crystalline carbonate of magnesia
(from Styria), with similar negative results. Solutions of gyp-
sum impregnated with carbonic acid were also allowed to remain
in contact with pulverized dolomite and magnesite during the
warm season for a period of six months, and even then only
traces of magnesia were taken into solution.

In one experiment out of many, 10-0 gr. of pure crystalline
dolomite from Galt ($82) and 1-0 gr. of pure crystalline gypsum

days, when the filtrate, freed from gypsum by evaporation and
the addition of alcohol, gave no trace of magnesia. The resi-
due was then treated for the same time with water holding car-
bonie acid in solution, and the filtrate having been evaporat
to dryness, gave to water an amount of sulphate corresponding
to a 0 of carbonate of magnesia for the 200 ¢.c., equal to
rssath of the weight of the dolomite. The digestion of a simi-
lar iS of dolomite and gypsum with pure water — r six
days at from 50° to 60° C., with frequent agitation, gave no appre-
— amount of soluble magnesian salt. When lesadiesade dol-
mite was digested at this temperature with a solution of pate
of calcium for twenty-four hours, an amount of chlori mag-
nesium equal to ;4;;ths of the dolomite was formed.
It was evident from these and similar experiments that no re-
nmi puey place between dolomite and solutions of gypsum

ev ° C., except in the presence of carbonic acid, whose
renee ation on pocerae ($79) causes the formation of a small
amount of s e of magnesia. It was then necessary to

search stools for an explanation of the origin of the magne-
sian sulphate found in the conditions observed by Haidinger
and Suckow.

the same time with 250 c.c. of a solution of gypsum satura

Production of dolomite.

§ 102. In $80 I have already discussed the conditions under
which ioe anhydrous double carbonate of lime and magnesia
may be formed, and referred to the sacperimeiie in a previous
paper in which ‘T had succeeded in producing it at temperatures
considerably above 100° C. It was with a hope of obtaining it
at lower temperatures that many of the experiments already
detailed in this paper were undertaken. Thus it was not im
sible that from the supersaturated solutions holding both the

mouocarbonate of lime and that of magnesia, a compound of
the two might be deposited. The experiments alread y described,
however, show that the carbonate of lime separates completely
after a time as a hydrate, without any trace of carbonate of
magnesia. Again it was hoped that the slow union of the two
carbonates at temperatures below 100° C. might give rise to the
anhydrous double salt, instead of which, however, we have seen
that there are formed the hydrated double carbonates already

escribed. Attempts were el made to dehydrate these com-
pounds and thus produce dolomite, but with partial success.

§ 103. The following experiments were made in confirmation
of those described in 1859. In the examination of the products
obtained, acetic acid was made use of as before, but with modifi- .
cations ($78). A dilute acid was prepared by mixing three
measures of the glacial acid with ninety-seven of water. Of
this liquid, containing three-hundredths of acetic acid, there
would be required in round numbers about 44 c.c. for the solu-
tion of one gram of dolomite, upon which the action is compar-
atively slow at the ordinary temperature, although this same
liquid dissolves carbonate of lime with lively effervescence. By
dividing into two or more portions the amount of this dilute
acid required to dissolve a given weight of a preparation of thé
two carbonates, and keeping separate the matters dissolved by
the successive portions, a fractional analysis of the material is
effected, which gives results still more satisfactory than those ob-
tained by the method described in the previous paper.

§ 104. In § 37 it was shown the anhydrous crystalline car-
bonate of magnesia evinces no disposition to combine with car-
bonate of lime, and the following experiments will show that
the crystalline sexhydrated carbonate of magnesia (§ 87) is but
little disposed to combination. A portion of this compound
was intimately mingled with an equivalent of precipitated car-

nate of lime and one-fifth of an equivalent of bicarbonate of
soda, which would at an elevated temperature furnish carbonic
acid that might aid the reaction of the earthy carbonates. This
mixture formed into a paste with water was heated in a closed
tube for two hours from 120° to 180° C., and then to 180°C.
After six hours the matter was removed, washed with water and

magnesia, while the residue was slowly but completely soluble
in hydrochloric acid, and was carbonate of magnesia with only
3°2 p.c. of carbonate of lime. From this it appears that a por-
tion of the double carbonate is formed in this experiment and
remains mingled with resulting magnesite. In another experi-
ment, in which no bicarbonate of soda was added, the portion
soluble in dilute acetic acid contained 90°3 of carbonate of lime
and the residue only 68 p. c., the remainder being carbonate of
magnesia. The result of these experiments, like that of von
Morlot, is thus chiefly a mixture of carbonate of lime with mag-

ia,

In the above asin all the experiments at temperatures over
100° C., here described, I have made use of bronze tubes hold-
ing about 14 c.c., with screw-caps made tight by an interposed
disk of lead, and heated in an oil-bath.

§ 105. It was next to be seen whether the hydrous double

sition of the successive portions was as follows:

These results show that as in the preceding section but little
SO is formed, though the proportion of lime which still
remains in Iv, 1 indicates a certain amount of the double salt.
The presence of nearly ten per cent of magnesian aren (in

with less ons one per cent in II, seems to be due toa partial
decomposition of the magnesian carbonate during its dehydra- .
tion, involving a loss of carbonic acid and the formation of
hydrate of magnesia. A similar result is seen in the second ex-

excess of carbonate of lime, and is is regarded by Dana as of
recent origin, and as derived, in some way, from the alteration
of coral mud. If this origin ‘be established beyond a doubt, it
is to be remarked that the separation of carbonate of magnesia
from sea-water requires peculiar conditions, which evidently are
rarely fulfilled in the case of these coral deposits; and its pro-
duction being conceded, the volcanic agencies so active in these
regions may have ver. well furnished the heat requisite to form
dolomite before the elevation of the island.

ArT. VIII.—Remarks on the new division i the Eocene, or Shell
Bluff Group, proposed by Mr. Conrad ; by Eue. W. HILGar D,
Ph.D., State Geologist of Mississippi.

In a brief paper published in the January number of this
Journal, Mr. Conrad proposes to distinguish, as a separate group
of the American “Mipeane, a series of deposits but feebly repre-
sented at Vicksburg by a five-foot stratum of dark lignitic clay
and sand, coats in its paleontological characters from both
the Vicksburg and Jackson group. Mr. Conrad considers it to
be especially characterized by the occurrence of Ostrea Georgt-
ana, and defines it as underlying the “ Orbitolite limestone of the
Jackson Group.” He also mentions, in the section of the Vicks-
burg Bluff, the Orbitolite limestone, as a representative of the
Jackson group.

The latter supposition is manifestly an oversight on the part
of my honored friend. That the group of fos sils described by
him, and figured in Prof. Wailes’s ‘Report, as J. sil ate do
not occur at Vicksburg, I need not recall to his mind; but he
has overlooked the fact that the Orbitoides Martelli thronahoue
the state of Mississippi, at least, is entirely absent from the
Jackson Group, the Orbitoides limestone being invariably
accompanied by Pecten Poulsoni, Arca yeah decile Ostrea
Vicksburgensis, and other leading Vicksburg fos

Of Ostrea Georgiana I have unfortunately never seen an au-
thentic specimen or description; but from the facts stated by
Mr. Conrad, and his comparing it to P. longirostris Lamk., Iu
hesitatingly seer u a specimens from Vicksburg, labeled

gan. by Prof. Wailes. Upon the authority of the
latter observer, Mr. Conrad mentions the occurrence of O. Geor-

and

times resembling closely G. convera of the Rotten Tigdetone.
It is one of the leading fossils of what I have most unequivo-

cally recognized as the upper member of the Jackson BrOuP ; it
occurs at Jackson itself, on the hill-tops, associated with .
glodon bones, Umbrella planulata, Cyprea fenestralis, Morio Peter-
soni, Conus tortilis, and others, in stratum No. 7 of section 27,
page 131 of my Report. The Jackson feuctta deseribed by Mr.
Conrad are derived hs Nos, 4 and 5 of that section.

In the numerous localities where I have studied the beds of
the Jackson group, I have never found a single Orbitoides asso-
ciated with them. The constant concomitant of the latter fossil,
the Pecten Poulsoni, ~~ is ee from the Jackson strata, being
replaced by P. nuper

But if the Grisiteides canadian is no member of the Jackson,
but on the contrary, a characteristic one of the Vicksburg group,
then it is clear that the strata of the “Shell Bluff group’
Vicksburg lie above, and not below the Jackson strata. For ws
cannot be supposed. that the latter, which occupy so extensive’
an area above Vicksburg (see the map accompanying my Report,)
should suddenly come to an end, and leave no trace of a repre-
sentative between the Shell Bluff pee the Vicksburg groups did
it belong there.

There is only one other locality in the state, as far as known,
where O. Georgiana (i.e. the large air occurring at Vicks-
burg) is found, viz: in Jasper county, Miss., where “it was col-
lected by Prof. W. D. Moore, late of the. University of Miss.
It there occurs again in the same outcrop with Pecten Poulson,
Orbitoides, and a Schizaster, which is also a leading Vicksburg
fossil ; this locality being Tikewise considerably south of the
shell prairies of the Jackson

As there is nothing to justify the assumption of a sudden
termination of the strata of the latter group, which, on the con-
trary, may be seen disappearing under those forming the transi
tion to the Vicksburg strata, with remarkable regularity, along
the course of both Pearl and Chickasawhay rivers, (see p. 135
of my Report), the conclusion is inevitable that the Jaakson group
as older than the Shell Bluff group as defined by Conrad.

hat there may be a considerable difference in the geological
horizons of the Jackson and Vicksburg groups proper, sufficient
“to admit of the existence of a fauna deserving to
into a distinet group, is proved, not only by the paucity of coin-
cident species, (see list, ibid, p. 182), but no less by the consid-
erable thickness of the intervening strata in eastern Mississippi,
on the Chickasawhay river, which near Red Bluff Station
(ibid, p. 185,) amounts to over one hundred feet.

Here, as at Vicksburg, we have, underlying the Orbitoides,
marls and limestones, a stratum of inconsiderable t ickness, but
literally teeming with shells, which are a strange mixture of the
faunas of Jackson and Vieksbur rg, with numerous peculiar
species (see list, ibid, p. 136). Here also, we have a Madrepora,
distinct from, but closely allied to, the eS ae in a

Before the blowpipe the mineral readily fuses on . the edges to

coating of oxyd of zinc. In a closed tube it loses color, but
gives off no water or any sublimate. It is perfectly decomposed

that the end may dip under water. The mixed bases, whose
total weight is known, having been placed in the nacelle in a

the process repeated. The result can be controlled by also
weighing the nacelle after the reduction of the iron, but it is not

K. J. FARQUHAR, Assistant Librarian U. S. P nt Office.

WALKING out between eight and nine o’clock in the evening
of Saturday, May 12, near Sandy Spring, Montgomery county,
Maryland, and looking over the constellations in the east, I was
surprised at the appearance—or apparition I may call it—of a
star in the Northern Crown which I could not believe I had
ever seen there before. Immediately on reaching home I looked
up an atlas of the heavens, and found no such star mark
upon it. I then walked over to the house of my uncle, Mr.
Benjamin Hallowell, who having looked at another ma of his
own, and found no record of such a star, came out with me to
see it, As soon asI had pointed it out to him, he remarked
that he had seen it for several nights, amounting to three weeks,
or as he afterwards said, a month, probably ever since the con-
stellation had come within view of a spot where he was accus-
tomed to take an sadian walk. He is therefore, so far as I
om the first person who ever saw it. He had remarked it as

unfamiliar star, and —— it was a tare ore consid-

of his oelcmed in that respect. There can be no doubt that
during at least part of that night, the stranger star was fully as
bright as Alphacca; I think brighter. Sunday morning it did
not seem to have changed in luster, but Sunday night it was
only of the third magnitude, and since that time it has gradually
faded from sight of the naked eye. On Tuesday night it was

Arr. XIIL—New and Brilliant Variable Star; by B. A. GOULD.
(In a letter to the Editors dated Cambridge, Jo une 9, 1866.)

On Monday evening, May 14, Mr. S. C. Chandler, Jr., of the
U.S. Coast Survey, while engaged i in observing the magnitudes
of fixed stars, by comparison without optical aid, perceived a
brilliant star not a degree from ¢Corone. At 11 P.M. he esti-
mated its light as between that of 8 and y Herculis, rather nearer
to the latter; it was decidedly brighter than 9 Boiss, and at
least two- thirds of a magnitude brighter than ? or 7 Coronex.

The sky had been obscured for several successive nights, but
Mr. Chandler is confident that, three weeks previous (at which
date he had examined the region with care), no star of sufficient
brilliancy to attract attention was visible in this place.

On the ensuing evening, May 15, at 9 p. m., Mr. Chandler and

myself examined the star together, and eae in Any wien its
brilliancy as not essentially different from that of 8 Coronsz or
y Herculis, and as right between the two. It was very

the ae on the 12th of May. For letters from ‘him I am in
debted to Robert Patterson, Esq., of Philadelphia, and to Prof.
Henry of the epieutir we Institution. He states that on that
evening, it was somewhat superior in brilliancy to « Corone;
and on other aines he observed or estimated it as follows: May
14 mag., somewhat brighter than @Coronze; May 17th,
less bright than Coron; May 19th, barely visible to the naked
eye; May 20th, only perceptible through a small spy-glass, 8th
mag.; May 24th, 10th mag. This last estimate must have been
an extreme one, very possibly in hazy sky and without compar-
ison-stars.

At an early day the star was also noted by Mr. Hallowell of
Alexandria, who has very recently communicated his observa-
tions to a Philadelphia daily paper, but I have not yet been able
to see them. Indirectly I have been informed that Mr. Hallo-
well has seen the star on athe occasions during the winter,

1850, in which the subject was thoroughly discussed, and I might

At that time I had discovered six new localities of emery in
Asia Minor, and the Grecian Archipelago. Those localities were
far removed from each other, and furnished so many different
places for the study of emery and its associate minerals in addi-
tion to the old locality of Naxos; and consequently many.points
of general interest were brought out, besides others connected
with the line of study. Those who may feel interested in the
subject will find the investigation and results there arrived at in
this Journal, vols. x and xi, 1850 and 1851; they embrace the
geology, mineralogy, ¢ chemical ¢ composition, manner of mining,
commercial Se aga associate minerals, &c.

The study of the associate minerals I considered of great
importance, as they pial be guides in future explorations in
ilies parts. of the world; and even prior to completing the re-
searches on the subject I wrote to Professor Silliman and
him to examine the American corundum localities for these
minerals, one of them in particular, which he immediately did.
With the corundum from the locality in Chester county, Penn.,
and Buncombe county, N. C., he “soon found the mineral indi-
cated,” and communicated the same to this J ournal, Nov. 1849,
pp. 879 and 383.

Nothing further came to my notice in relation to emery until

Accompanying the letter he sent me a paper giving mea sum-

I have since visited the locality, having done so in the month
of March last. The geological character and position of the
rocks was not as well made out by me as might have been done
in a more favorable season; but as my observations accord, as
far as they go, with those of Dr. Jackson and Prof. Shepard, I
prefer inserting their observations, rather than my own, in de-
scribing the geology of the emery ‘localit ity.

“The mine is situated nearly in the center of the Green Moun-
tain chain as it traverses the western border of the state, at a

7 pene not far from half way between the Connecticut and Hud-
rocks,

It is included in the metamorphic series of
consisting of vast breadths of gneiss and mica-slate, with
considerable interpolations of talcose slate and serpentine. The
general direction of the stratification is N. 20° E. and S. 20° W.,
the relation to the horizon varying from vertical, to a dip of from
75° to 80°, sometimes east, sometimes west.

86 J. L. Smith on the Emery mine of Chester, Mass.

“The immediate vicinity of the mine presents a succession of
lengthened rocky swells with rather precipitous sides, having
summits between 750 and 1000 feet above the level of the prin-
es streams by which the hills are traversed. The longer axis
of the elevations generally coincides with the directions of the
strata.

estimated at 750 feet.

“The emery vein, whose average width may be taken at four
feet, is situated near the junction of the great gneiss formation
constituting the western flank of the mountains with the mica-

orming the eastern slope. T'o speak more exactly, how-
ever, it lies just within the gneiss, having throughout a layer of
is rock of from four to ten feet in thickness for its eastern wall.
Nor does the mica slate advance quite up to this outside layer of
the gneiss; but in place thereof, an extensive intrusion of tal-
cose slate occurs, having an average thickness of twenty feet on
the south mountain, and widening out at the north mountain to
a breadth of nearly 200 feet as it reaches the terminus of the
vein, in the bed of the Westfield river.

“The gneiss, more especially in the vicinity of the vein, is a
very peculiar rock. It abounds in thick seams of a coarse-
grained, very black and shining hornblende; and where this is
not found, it is much veined and penetrated by epidote. The
stratification is much contorted also; and when the surface of
the formation happens to be weathered or water-worn, its basset-
ing es strikingly resemble in color some of the serpentine
marbles. It is also noticeable that in it quartz is everywhere

like the gneiss again, are strikingly free from quartz or uncom-
bined silica in any of its forms. Indeed this generally abundant
substance is altogether wanting, not only in the emery-vein but
in the talcose formations constituting its eastern bounda:
t makes its appearance, however, in abundance in the mica

slate as soon as the taleose rocks are passed—showing itself not

only as the usual ni a tae of the slate, but in more or less
continuous seams, a few inches thick up to above six inches,
and sometimes a foot, j in width. Where the seams are thin and
discontinuous, the included masses thin out at each end beens
a the sharp edges being curved in opposit® diree-
tions, so as to form frequent white patches upon the surface of
the rocks in the shape of the letter 8.”

Mineralogical Character and Composition of the Chester Emery.

It resembles more nearly that from Gumuchdagh — Eph-
esus,) than any other that I know of. It is of a fine grain, and
dark blue bordering on black, not unlike certain variate of

magnetic iron ore; with it there are frequently found pieces of
corundum of some size. The interior of the mass is free from
micaceous specks, such as are found in the emery of Niles Its
powder examined under the microscope shows the distinct exist-
ence of more than one mineral, which are often so inseparably
connected that the smallest fragments contain them together.
The two predominating are corundum and magnetic oxyd of iron.

Several s were submitted to chemical examination
from sees most largely impregnated with Scone ince of

iron to those that appeared to contain least. They all consisted
essentially of alumina and oxyd of iron; aoe I invari found
a little titanic acid and silica, and most ¢ monly a mag ute

quantity of magnesia. No. 1 was an ceberion é specimen; No. 2,
the better quality of rock; No. 3, the emery rock mea et and

All the chemical and physical examinations made go to show
that the emery of Chester is, like all other emeries, a mixture of
corundum and nts - iron; a@ fact that will be reverted to
again a little farther

Prof. Jackson amaizied two specimens, after digesting them
with nitro-muriatic acid, and has given as the composition,

and a goes on to state, ‘from which it would appear that

proto of iron is an essential chemical ingredient in emery,

and not an accidental admixture.” Dr. J. Lawrence Smith’s ex-
po lead to the same result, but he considers the oxyd of
n to be an irregular mixture with the alumina and not a reg-
ula chemical constituent. In either case, I think emery ought
to rank as a separate species, and not as a granular variety of
po ea from which it differs so in physical characters.”

Iw ould here remark that Dr. Jackson's conclusion would be
correct in the first state of the case, were the iron an essential
chemical Fionn: but in the latter, it would be erroneous, and
introduce inextricable confusion into the science of mineralogy
by 89K 4 mere mechanical mixture as a specific distinction.

Prof. C. U. Shepard writing on the same point says, ‘ His con-
clusions (Dr. Jackson’s) would obviously be acquiesced in were
it not for the strong resemblance in striz and cleavage between
the emery and common corundum, making it impossible for us
to separate the substances erystallographically from one another.

othing like a hare crystal of emery has yet been found at
the mine; but it is quite remarkable that the mineral is here
generally’ coarsely massive, or in large separate individuals often
of the size of kernels of Indian corn, whose cleavages are per-

and which present on their planes the delicate strize so char-
tie Cer of corundum from the Carnatic.’”’ Yet Prof. Shepard

“Those emeries which contain the least water, everything
else alike, are the hardest, as instanced by that from Kulah, not-
withstanding the quantity of iron it contains. The silica exist-
ing in emery is most often in combination with alumina, or the
oxyd of iron, or both; for this reason we must not always re-
gard the quantity of alumina as an indication of the quantity of
corundum in eme

In concluding this part of the subject I would state that while
T do not consider my opinions infallible in this matter, still all

my experience and research, gathered from suc varied sources,
point to the conclusion that emery is a mixture of —_ min-
erals, principally corundum and magnetic oxyd of iron,
former being the effective agent in the mechanical “thane to
which it is applied; the o oxyd of iron is not to be considered as
an unimportant ingredient, it serving by its presence to eee:

found with the emery, seem distinct and separate to be at

Diaspore.— ery excellent and beautiful specimens of be

Corundophalite proved to be a chlorite——About the time I pub-
lished my memoirs on emery in 1850 and 1851, Prof. Shepard
made the announcement of a new mineral (this Journal, 1851,
xii, 211), stating that it “occurs with corundum near Ashevi lle,
in Buncombe Co., N. C., in imperfect bene groups, and also
spreading out in laminze between layer corundum; color
leek-green, etc.” An analysis of it showin silica 34°76, protox.

per cent, a portion © which he attributes to alkalies ; neither lime

nor magnesia were detected. He operated on 140 milligrams ;
this mineral was considered a new one, and Prof. Shepard called
it corundophilite. Supposing that I had observed the same
‘mineral in certain specimens of emery and emerylite from Ches-
ter, Mass., I enclosed a fragment of the specimen to oe S. to
ascertain if this was the mineral he called co ; he re-
turned the specimen, announcing that it was. I then analyzed
the same and found it to be, both chemically and pt bemer Fs
chlorite, identical no doubt with the chlorite I found associated
with the emery of Asia Minor; both the Asia Minor and 1 Chester
varieties occur in compact mass, composed of an agglomeration
of small crystalline plates—identical with the chlorites of Mont
des Sept Lacs and of St. Christophe, and the ripidolites of Rauris
and St. Gothard. In the following analysis I do not pretend to
furnish that of the pure mineral, as from the thinness of the lay-

Art. XVI.— Evidence of Two distinct femme Formations in
the Burlington Limestone; by W. H. Nixes and CHARL LES
‘W ACHSMUTH."

Dr. CHARLES A. WuirTE was the first to record any natura)
division of the Burlington limestone. In the Journal of the Bos-
ton Society of Natural History, vol. vii, No. 2, Dr. White has
given a “Section of rocks exposed at Burlington.” He there
describes eight beds, which he numbers from the lowest upward.
He refers the first six beds of his section to the Chemung group,
and beds “No.7” and “No. 8” to the Burlington limestone.
In vol. ix of the Proceedings Bost. Soc. Nat. Hist., and in
of the Journal of the same society, Dr. White describes certain
species of fossils from the Burlington ro¢ks; and although he
gives the beds or divisions in which the s ecies occur, yet no-
where does he claim that the Burlington limestone comprises
more than one geological formation.

r own observations have led us to regard these two divis-

classification of these strata.

The strata of the Lower Burlington limestone present many
differences in color, structure, and composition; but by intimate
acquaintance they can generally be distinguished from those of
the Upper Burlington limestone by their lithological characters
alone. In the upper part of this formation the limestone strata
become interstratified with beds of chert, and the uppermost
stratum of chert, which attains any considerable extent and
thickness, forms the division between the Lower and the Upper
Burlington limestones. This stratum of chert, in the vicinity
of Burlington, is from two to three feet in thickness. The

appears from the fossils, that it was during the latter formation
that crinoids culminated in extravagance of size and features.
Three grades of crinoidal development are thus exhibited: by
the species of the Lower ie those of the Upper Bur-

that there was something connected with the presence of siliceous
matter in depositing waters, during the formation of the uppe

‘beds of the Lower Burlington Limestone, which was unfavor-
able to the growth and life of the inhabise Crinoids; for, with
the introduction of the chert deposits, the Crinoids | appear to
have declined, and finally all of the species became extinct be-
fore the completion of the dividing stratum of chert above men-
tioned. A parallel instance is to be noticed in the fact that
there is a stratum of chert between the Upper Burlington and

I shall assume then that we have an axis revolving once per
second with a uniform motion. It is immaterial, of course,
whether this uniform motion is obtained through the spring-

forming a fork ; at the other end it has a little projection (2).
The arm // is delicately pivoted at (x), and at the other extremity
passing freely between the pins of the fork (y) carries the steel
pind. Atthe middle it is expanded into a ring, gg, through
which the arbor B passes without touching: ff is made of soft
iron, and the annular expansion at the middle thus serves for
the armature of the electro-magnet whose action is to produce
the desired result at the touch of the observer's key.

A light spring between e and f solicits f to the left, and thus
whenever the electro-magnet is not acting keeps the pin d in
the position represented in fig. 2, engaged with the arm b. In
this state of things the type-wheel ¢¢ will be carried round con-
tinuously by A. Of course the arms e and f must be as light as
consistent with sufficient stiffness, and their weight must bal-
ance in all parts of the revolution, and neither tend to accelerate
or retard the motion of the type-wheel.

Close behind the arms e and / is placed a stationary dise of
metal, H H, having one hundred equidistant holes pierced in it
in a circle, so situated that whenever the arm / is drawn to the
right by the magnet (thus disengaging the type-wheel from the
train) the pin d will immediately enter one of these holes, stop
the type-wheel, and hold it in place until the magnet ceases to act.

his magnet is peculiar in having for its core, instead of a
solid rod, an iron tube, through which the axis B passes. Thus
the pole of the magnet is always in the same position with ref-
erence to the armature gg, notwithstanding its revolution. As
only one pole of the magnet acts upon the armature it is neces-
sary to make the coils more powerful than ordinary.
| or bringing the hammer down upon the paper and movin

the paper along after each impression any one of many different
plans might be used. Probably the best, leaving expense out
of the account, would be to have the hammer raised by an inde-
pendent train of wheelwork, which should be unlocked by an
electro-magnet at the instant of observation, thus releasing the
ammer, and allowing the wheelwork after the blow to move far
enough to raise the hammer again, and carry the paper forward,
nother more simple plan is to work the hammer directly by
& powerful electro-magnet, to which the magnet Z should act as
a relay—that is, whenever the pin d touches the disc H it should
establish a current which should bring down the hammer upon
the paper; the hammer in rising after the blow carries the paper
along one space.

rovision is also made for carrying the paper along several
Spaces at the will of the observer, so as to leave an interval be-
tween the record of different stars.

Although there are only fifty numbers on the type-wheel_

either come in line wit which gives the whole seconds, or
half a space above it, hoe 25°18 or 258; the first would be
read twenty-five and eighteen hundredths, the second twenty-
five and nineteen hundredths.
_ It is not intended to secure precise coincidence of error be-
tween the clock and chronograph—merely coincidence of rate.
This is obtained by controlling the pendulum of the spring-gov-
ernor from the clock. The type-wheels can be set so as to indi-
cate the nearest whole second; and then the exact difference be-
tween the clock error and the chron ograph error can easily be
found by making the clock record itself Seeanieleally at the be-
ginning of a minute.
The operation of the instrument is then as follows. When the
observer oe his key, the magnet Z acts upon the armature,
and withdraws the pin d from its engagement with 4, causing it
to plunge Pao one of the hundred holes in the dise H. The con-
tact of d with H in its turn, by a magnet not shown in the cut,
brings sai the hammer upon the paper 0 0 and forces it against

‘THE object of the following note is to point out briefly the

The accompanying general section will serve to illustrate the e
topographical and geological features of the region under consid-
eration. The line of section extends from the Cumberland
mountain, or table-land, in “Putnam county, Tennessee, through

several years after petroleum was gathered at this point for me-

it is now impossible to tell. I give it simply as a good exam-
ple of an oil reservoir actually tapped in the Mountain limestone.

2d. In the Siliceous group. ‘There are several examples in this
formation of reservoirs reached by boring. At in the section
the geological (not geographical) place of the “ Porter well” in
Allen county, Kentucky, is represented. This well is located
on Bay’s Fork of Big Barren, on a line between Scottsville and |
Bowling Green, and “about seven miles from the former place {
and eighteen from the latter. This reservoir was ta , some
time in January of this year, at the moderate depth of 55 feet.
It yielded for a number of days, by pumping, about 400 barrels
of oil and strong brine per day, half of which was oil. At the )
time of my visit, Feb. 18th, it had produced altogether about
1000 barrels of petroleum, but was not then doing well.

In the southern part of Overton county, Tennessee, on Spring
creek, is another example. Here a reservoir was struck which
yielded heavy oil, but how much I am not informed.

3d. In the Black Slate. On Boyd’s creek, near Glasgow, Ken-
tucky, is a group of half a dozen wells or more. Their position
is shown by the heavy vertical lines atc. One or two of these
met with oil in the Black Slate.

M. C. Lea on the detection of Iodine. 109

Art. XX.—On the detection of Iodine ; by M. Carry LEA.

WHERE iodine exists in the form of hydriodie acid, or the
iodid of a base, two methods are commonly employed to put it
into a condition to be detected by the starch test. One of these
is by the action of nitric acid, the other by chlorine or bromine
water. The latter is the more delicate, but has the disadvantage
that if the chlorine or bromine be added in excess, the reaction
is missed.

It occurred to me while engaged in testing for iodine, that the
facility with which that body is eliminated from its hydrogen |
and metallic combinations by chromic acid would make the latter
substance a valuable means of bringing about the starch reac-
tion, and a few experiments completely confirmed this view.

If, for example, we take an extremely dilute solution of iodid
of potassium, such that the addition of nitric acid and starch pro-
duces no perceptible effect, the further addition of a single drop
of very dilute solution of bichromate of potash will instantly
bring about the characteristic reaction.

When chlorhydric acid is substituted for nitric, the effect of
the bichromate is (as was to be expected) still more marked.
The test has then the full delicacy at least of the chlorine test,
with this great advantage, that an excess of the reagent does
not prevent the reaction.

As to the delicacy of this test, the following observations
were made.

With solutions of iodid of potassium up to one hundred thou-
sandth (1: 100,000) the precipitate was abundant, becoming less

lue and more tawny as the dilution increased. Beyond this
point the distinctness rapidly fell off. The indications were ob-
Servable at one-four-hundred-thousandth. With a solution of
one-eight-hundred-thousandth it was doubtful whether any effect
was evident though still it was thought that a darkening was
produced.

The experiment can be made in two ways, according to the
result desired.

If it is wished to observe the effect of the chromic acid in in-
creasing the delicacy of the indication, add the acid and starch
to the very dilute solution of iodid, and then when the extreme
dilution is such that no reaction appears, a drop of solution of
bichromate instantly produces it. _

But in employing the reagent in the search for iodine, add
the starch to the liquid to be tested, stir it up, add a drop of
dilute solution of bichromate, enough to communicate a ale
pe color, and finally add a few drops of chlorhydric acid,

or in case of great cane atin to a half-millionth,
merely a tawny shade n to the s

It seems scarcely necessary to say that if a very great — .
acid is used, and too much bichromate, the starch may be
to reduce the Sdhacinaate: Even this, however, cannot decciva
for a bluish-green solution is thereby produced, whereas the in-
dications of iodid are in the order of their strength : blue pre-
Cipitate, tawny precipitate, tawny solution. Unless in the case
of very exceptional dilution above spoken of, a well marked
blue precipitate is always obtaine

The examination of the delieuey of the reaction yee very
dilute solutions was made at a temperature of 65° F. or there-
_ abouts. sp fact requires to be taken into account, as “anos

e experiments of Fresenius to be found in the Jabres-

bericht for 1857, the delicacy of the starch test increases as the
temperature falls, so that at 0° C. a fainter trace can be ren-
dered evident than at 12° C, and so on: the difference is as-

sert

to be material. Fresenius’s experiments were made with
sulphuric acid ne! hyponitric pat and the delicacy of the reac-
tion obtaine him at corresponding temperatures seems to

fall a little short of the above.

rd, otherwise whatever is condensed or projected upon it will flow
downward and the product be contaminated, at least, with lead. Into
this tube a smaller one of platinum is luted, which is bent into the shape
of a quarter of a circle so that the farther end points downward ; this
end is soldered with gold into the bottom of an inverted platinum eruci-
ble. An old one, ipo and cracked, suc as is generally to be

immersed in “water sank ed in a ear not very much ey Dea it in
diameter, offers a large surface for the absorption of the acid gas, while
a retrocession of the liquid from absorption or change of temperature is
impossible.

The cover to the retort may be cast in one piece with a shoulder, or be
made of two discs of lead of the size of the inner and outer diameters of
the bore, and held together by a ring of lead cast into them and serving
asahandle. For a lute I spread a thin layer of gypsum on the surfaces

the name Gilberisocrinus, is whether it may not have to give way to the
older name Ol/ucrinus Cumberland, 1826. If de Koninck, Pictet and
others are right in the opinion that Ol/acrinus was founded upon one of
the same types as Gilbertsocrinus Phillips, 1836, then Cumberland’s
name must take precedence, and our American species described under
the names Zrematocrinus and Goniasteroidocrinus will have to take the

sink other wells, hoping to obtain a stronger brine. After digging
fifteen feet, one of the negroes employed struck a hard substance with
his pick-axe, and was desired by the owner to go on and throw out some .
of the supposed rock. On washing off the excavated mass, it proved to.
be pure, hard rock-salt.

The area found, at which, by probing to the depth of from 15 to 18
ft., rock-salt was struck, indicatés that the deposit underlies several square
acres, perhaps four to six. The materials passed through, to reach it,
are chiefly bluish clay, sand and gravel, with some lumps of micaceous
sandstone. At the above depth, within that area, under every place at
which they have bored or dug down, they reac ched the solid’ rock-salt.
Through this solid scraban they bored twenty-six feet, and still found the
salt deposit.

In getting it out for sale, it was found necessary to blast in the usual
manner for obtaining building rock; and, even after purchasing moderate-
sized Jumps, the consumer has considerable difficulty in reducing them
to asize fit for use. This compactness seems also to protect the salt from
deliquescence, and even to enable it for a long period to resist solution

when immersed in water. He was assured that large Jumps, packed in
barrels, had been sunk in creeks and ponds for concealment, and taken

up weeks esis scarcely at all diminished 3 in bulk.

The accumulation of 15 to 18 feet of clay, sand, and gravel on the
deposit ee evidently been the result of comparatively recent washings
from the adjoining hills; and the deposit has, no doubt, been worked by
the aborigines, as, at more than one place, on reaching the rock-salt,
Indian relics were ‘found. He saw, at Mr. Henshaw’s, a basket, obtained
from the surface of the rotates 15 feet below the surface of the soil,
made of split cane; and was informed that they also found pieces of

the facts, and, after having obtained and closely inspected numerots
specimens of the r ock-salt, gravel, — s of sandstone, and one very fine
erystal, over two inches cube and nearly transparent, a all of which are
now in the Indiana State University, he felt assured that the whole phe-
nomena must be referred to aqueous action.

In all probability, the semicircular deposit of sand and gravel, thrown
to the height of 160 feet waa web inet to the contour of the
sea coast, resulted from the combined action of the winds and the waves
of the ocean. In a similar manner, gaciets ridges of nearly the same
height have formed on the south shore of Lake Michigan, conforming to
its coast outline; the latest and most northerly being close to the water's
edge, . having formed since the settlement of the country by the

Whether or not the explanations here offered of the interesting phe-

important; and the evidences remain there to be examined at any time
by those interested. The locality can be reached by railroad travel of

for this class of subjects. While many of the figures have appeared

Tn_addition to the descriptions of the species there is also given a great
amount of information concerning their embryological development and
growth and anatomical characters, which renders the work far more val-

their true position, but we cannot see that their bilaterality is destroyed
thereby, or that this conflicts with their Acalephian character, since bi-

1. Padnaten: —The zero of the emg magnet, or the
position of the magnetic axis on its scale, was determined by
inversions each month, and its readings on rite circle referred to
a distant mark of known azimuth. On four days about the
middle of ich month the declination readings were recorded
every half hour, between the morning minimum and the after-
noon maximum, generally between the hours of 6 A. M. and 2
P.M. Hach monthly declination result is therefore the mean
from observations made on four days.

To obtain es mean declination of the day or that value
which would result from 24 hourly observations, a small cor-

greatest declination of the day gives the west declination too
large, as does also the — of the half hourly readings between
those extremes, the amount of excess being the same. We

Arr. XXIT.—On the Age of the Coal Formation of China; by
Dr. J. S. Newperry: addressed to RaPHAEL PUMPELLY, Esq.

THE fossil plants you were kind enough to submit to me for

152 J. S. Newberry on the Coal Formation of China.

This conclusion is based on the entire absence of Carbonifer-
ous plants from the collection; and the presence of well marked
Cycads—species of Podozamites and Pterozamites—closely allied
to, if not identical with, some heretofore found in Europe and
America.

I give below such descriptions of the several species contained
in the collection as could be framed from the somewhat meager
material submitted to me. Future observations made upon a
larger number of more perfect specimens will be necessary be-
fore questions of specific identity or difference can be definitively
settled, but it is scarcely probable that any facts or specimens
hereafter to be obtained will require a modification of the view,

plants new to science, but the Pecopteris, Sph Pi m-
ates, Plerozamites, &e., have a very familiar look; and in their
resemblance to well known fo resh evidence of the

monotony of the vegetation of the globe previous to the intro- 4
duction of the angiospermous forests of the Cretaceous period. 3
Whether the strata which have furnished these plants should
be considered Triassic or Jurassic remains to be determined by
future observations, as the fossils yet obtained can hardly be
considered sufficient for the solution of that question.

from those of a European Jurassic species (P. lancolotus Lind.).
Still, the evidence of identity is much stronger in regard to the
former species than the latter.

From Piyunsz we have a fine Pecopterts with the falcate
pinnules so characteristic of the Mesozoic species, and, indeed,
very accurately copying the form of P. Whitbiensis, a Euro
Jurassic species; but unfortunately the strata which contain this
fossil have been much metamorphosed, the coal converted to
anthracite, and the nervation of the fern has been entirely
obliterated, while the outline remains distinct.

Probably it will be found as difficult—or rather as impossible
—in China, as it has proved in this country, to identify all the
subdivisions of the Mesozoic strata discernible in Europe. Yet
we shall doubtless gather there new proofs of the constancy of
the order of sequence in geological history, and new evidence of
the stability of the foundations on which geology as a science
rests.

I have under my eye, as I write this letter, four collections of
fossil plants, which, though from very widely separated locali-
ties, are curiously linked together. They are,—

ist. Fossil plants,—Cycads and Conifers,—collected by my-
self from the “Gypsum Formation” (Triassic) at Abiguiu, New
Mexico. Of this collection the most conspicuous and interest-
ing plant is Otozamites Macombii N. :

2d. A collection of fossil plants—Cycads and ferns—received
through Prof. J. D. Whitney from Sonora, Mexico, where they
occur with coal strata and Triassic mol ‘

In this collection Otozamites Macombit is associated with Stran-
geriies magnifolia Rogers, Pecopteris faleatus Emm., and other
plants occurring abundantly in North Carolina. |

d. A collection of fossil plants—Cycads and ferns—from N.
Carolina and Virginia, including, besides the last two mentioned,
and many which are new, several species apparently identical

bieria, Laccopteris, &c. ; “a among other Cycads, Podozamites Em-

4th. The collection made by yourself in China—Cycads and
ferns—in which one of the most distinctly marked plants is
P. Emmonsii.

In regard to the American localities cited above, there is per-
haps no good reason for our withholding assent to the conclu-
Sion that the rocks furnishing the fossil plants, are Triassic, but

154 E. L. DeForest on a method of correcting monthly means.

when we remember how much difference of opinion there has
been, and indeed still is, _— pet subject, even in the light of
large deletions of fossils, n hardly with propriety offer
even a conjecture as to the sete age of the Chinese coal strata.

0 recapitulate. One species of Podozamites contained in the
collection is apparently identical with an American Triassic spe-
eies; the other more resembles a European Jurassic plant. The
Pterozamites resembles both Triassic and Jurassic species, but is
identical with neither. The Pecopteris has certainly a remark-
able likeness to P. Whitbiensis, which occurs both in the Liassic
and Oolitic floras; and it is not yet certain ap it is not also
found in the Carolina and Richmond coal basins.

The Sphenopieris and Hymenophyllites are altogether new, and
suggest no affinites of value in this connection—while the "Tax
ttes, Hquisetites, &c., are too obscure to afford us any help.

ArT. XXITI—A Second Method of correcting Monthly Means for
the unequal length of the Months ; by Erastus L. DEForEst.

In the May number of this Journal I gave a system of neh
equations for finding the mean temperature, rain-fall, &c.,
any mean month in terms of the means for the three nearest ost
endar months. This was done on the supposition that the curve
of daily temperatures for any three consecutive months may be
represented by a portion of a parabola whose equation is

y=a+be+cr?,
A similar system of Sec ong may be found by assuming that

tion of the substance as the sulphur or chlorine, in a manner sim-
ilar in other respects to that described for simple hydrocarbons.’

In pursuing this research some difficulty was experienced, as
was anticipated, in finding a substance which would absorb and
retain the whole of the chlorine, under conditions that would at
the same time insure that every trace of the carbonic acid and
water should pass through unabsorbed.

The search for this substance was confined to the oxyds of the
heavy metals, as these alone, from their strong affinity for chlo-
rine, and weak affinity for carbonic acid, seemed to give encour-
agement of success.

The difficulty, however, in finding such a substance was chiefly
due to the circumstance that most of the chlorids of these metals
are either too volatile, or begin to suffer decomposition at too
low a temperature; it being requisite that the absorbing sub-
stance, and the newly formed chlorid of the same, should bear
to be heated sufficiently to prevent both condensation of water
and absorption of carbonic acid, and at the same time avoid a
temperature high enough to occasion any appreciable decompo-
sition of the chlorid.

viment 1,—A mixture of oxyd of lead and asbestos was
placed in the anterior end of the combustion tube, between
c and d, fig. 2, as previously described. As chlorid of lead was
supposed to bear a pretty high temperature, without volatiliza-
tion or decomposition, the use of the air-bath was omitted in this
experiment, and the oxyd gently heated with a small flame from
ée combustion furnace. The combustion had not proceeded
far when it became apparent, from deposition of minute drops of
liquid on the sides of the vacant part of the tube,—from 6 toc,
fig. 2,—that the combustion of the chloloform was incomplete,
although no doubt could exist as to the presence of an excess of
oxygen. This deposit of liquid, which, as already stated, was
supposed to be a chlorid of carbon, was found to be difficultly
volatile, suffering partial decomposition, and leaving on the tube
a brown deposit, which was not entirely removed by ignition in
a stream of oxygen. The high temperature employed to burn
off this deposit occasioned excessive heating of the posterior end
of the mixture of lead oxyd and asbestos; and this may have
n the cause, to some extent, of the excess in the determina-
tions of carbon and hydrogen, although subsequent analyses indi-
cate that the sample of chloroform under examination contained
a larger percentage of these elements—particularly of the latter

he mixture of asbestos and oxyd and chlorid of lead was remo-
ved from the tube, and treated in the usual manner with a solu-
tion of bicarbonate of soda to obtain a soluble chlorid. This
operation was found extremely tedious. Even after treatment
for more than two weeks, with occasional fresh portions of the
bicarbonate and frequent agitation, the decomposition of the
lead chlorid was still found to be incomplete, and the operation
was abandoned. As this is given in the text books as a good
process for the separation of chlorine from chlorid of lead,* I am
led to presume that in this case the excess of heat employed
gave rise to the formation of an oxychlorid, which is, doubtless,
more slowly acted upon by the bicarbonate. This single exper-
iment does not, therefore, prove that oxyd of lead may not be
employed in this process with good results, when used for easily
combustible substanees, and excessive heat is avoided. But it
will, unquestionably, be found preferable to use a substance
which will give directly a soluble chlori

the impression gained by the preceding experiment,—that chlo-

IV, Experiments with Oxyd of Copper, as absorbent of Chlorine in the
analysis of substances rich in Hydrogen.

In these experiments, for the reason previously stated, the oxyd
of copper could only be placed in the anterior end of the com-
bustion tube, where it might be maintained at a tolerably low
temperature. After two or three experiments,—which were but
partially successful,—it became apparent that the range of tem-
perature within which oxyd of copper could be made serviceable
to absorb the chlorine was probably rather limited.

t was observed, for example, that at 150° to 160° even brown
oxyd of copper, which had been but gently ignited, would fail
to absorb nearly all the chlorine, and consequently the determin-
ation of the carbon, and sometimes that of the hydrogen, would
be in excess. In one experiment, in which the oxyd of copper
was kept at about 153° C., its appearance had suffered no change,
and it was found to contain only 8:29 per cent of chlorine, or
only about one quarter of the theoretical quantity. When a
sufficiently high temperature is employed, on the contrary, the
posterior end of the column of oxyd of copper and asbestos has
the appearance of being entirely changed into yellow chlorid of
copper, the rest of the column remaining, for the most part, of
its original dark color.

In another experiment, with the oxyd of copper kept at a
temperature of about 160°, only about fourteen per cent of chlo-
rine was obtaine

In both of these experiments the carbon determination was
considerably in excess, and in one of them the hydrogen also.
The oxyd of copper employed had been strongly ignited.

Before proceeding further with these somewhat random exper-
iments, it was deemed advisable to determine the temperature at
which chlorid of copper begins to give off chlorine, in order to
know how far it would be safe to raise the temperature of the
air-bath in conducting an analysis. By making use of the air-
bath to regulate the temperature of the chlorid of ones this
determination was easily made. During the heating of the chlo-
rid, a current of air from the air-gasometer was admitted through
the tube in which it was contained.

bservations.—At 243° not a perceptible trace of chlorine was
givenoff. After the lapse of fifteen minutes, at 250°, the nitrate
of silver into which the gas was conducted, was observed to be >

slightly milky; this may, therefore, be taken as about the tem-
perature at which chlorid of copper begins to suffer decomposi-
tion. At 267°, a solution of nitrate of silver was instantly pre-
cipitated.

Thinking that perhaps the small quantity of chlorine evolved
under these circumstances might be taken up again and retained
if oxyd of copper were present, and possibly, also, that in that
case a higher temperature might be safely employed,—to make
the conditions of the experiment conform in this particular to
those which exist in an analysis, all but one inch of the chlorid
of copper was removed from the tube, and in its place was
put a mixture of asbestos and oxyd of copper, occupying a space
of four inches in length, forward of the chlorid. The experi-
ment was then repeated. Prolonged heating in a current of air,
and afterwards in oxygen, during which the thermometer rose
to 350°, produced no reaction with nitrate of silver. From this

the combustion there was no appearance of chlorid of copper,
except in the first half-inch at the back end of the column of
the mixture of oxyd of copper and asbestos; showing that the
temperature employed was favorable for rapid and complete ab-
sorption of the chlorine.

Analysis 3—Under the impression that an oxyd of copper

paused from 150° to 158°. ~ e space occupied by the asbestos
mixture was four siahies in length, and contained three grams
of the oxyd. Although the results of the analysis indicate that
the temperature of the air-bath was too low, they also show, by
comparison with the results obtained in = ogee with strongly
ignited oxyd at about the same temperature of the air-bath (see
p. 163), that the brown oxyd is decidedly scorers in respect to
the temperature required. This was also shown by the appear-

close of the combustion, from extending the heat backward too
soon, under a wrong impression that the substance was all burnt.
Were it not for this circumstance, it is believed that this would
have been a good analysis, although the temperature of the air-
bath was kept so low. That a higher temperature of the bath
is desirable, however, is shown by the fact that the chlorid of
copper appeared diffused over a space of 24 inches. The length
of the column of mixed asbestos and oxyd of copper was only
four inches in this experiment, containing but one gram of the

Art. XX V.— The Vowel Elements in Speech ; by SAMUEL PoRTER,
of Hartford, Conn.

THE division of the alphabetic elements into vowels and con-
sonants is one which grammarians have ever been compelled to
recognize, however hard they may have found it to mark the
distinction by satisfactory definitions. The nature of the vowels
is such, somehow, that every word must contain at least one of
them. The same is true, for the most part, of syllables as well
as words. The consonants J, n, r, m, do indeed occasionally
take the place of a vowel in a dependent, unaccented syllable,

times properly, and sometimes by a slightly incorrect pronunci-
tion. Br nd no syllable under a full accent, is
without a vowel. rare exceptions which may occur, as in

Vienna, the author of a most thorough and able treatise on
phonology, remarks that ‘the formation of the vowels still pre-
sents to us considerable theoretical difficulties, which it will take
a long time perhaps to solve ina satisfactory manner.”’ Prof.
Max Miiller, in the second series of his Lectures, treats the phys-
iology of the vowels with a good deal of particularity, but
makes no attempt to present a complete and exhaustive scheme.
In short, a true system of the vowels has thus far remained &

When all is iote so far, there remains the task of making

criminating ears and loose habits or incorrect modes of pronun-

All the vowels are articulated primarily between the

no other or further criterion; for, in their case, the more or less

palate
The scheme does not contemplate a precise admeasurement of
vce and close as between vowels of different groups; it requires
h comparison; it deviates from other systems in this, es-
agkliy, that it assigns to different places, and thus ranges under

ploy. In all our modern tongues we have many more than the
three original vowels of the Sanskrit and the Gothic,—though
we can hardly doubt that these three admitted severally consid-
erable latitude of variation. In English, we recognize as
distinct many more than we have separate characters for; while
over and above these, we may notice slight variations, as due to
the influence of associated consonants, or in connection with
varying accentuation or emphasis; and, in the pronunciation of
different persons, and even of the same person at different times,
we observe appreciable shades of difference in what will be
usually regarded as the same vowel.

n all the vowels alike, the sound proceeds from the larynz,
being struck out upon the chords of the glottis, which, when
drawn near each other to the proper interval and duly con-
tracted, are set into vibration by air forced through from the
lungs; the sound is then modified into this or that vowel by
reverberation through a passage of this or that description. In

for instance, the so-called short sig in full, a fet into the
corresponding long in fool, pool, rule, food ; nor will any process
of curtailment convert the latter into the former. This is but
an example of what is true universally of the vowels in the
English, and to a greater or less degree in all languages. The
tendency to variation of quality when a vowel is lengthened or
shortened, is natural and universal.

etymology: the differing relations of the long and of the short,
which they must and do recognize, are quite unaccountable on
their view of the case. If we lay open the physiological ground
of a difference here in quality, we do so much to place etymo-
logical science upon the right basis.

. There are questions concerning xis feng * the vowels to
tone or pitch. Have the vowels each what may be called in any
sense their natural pitch? “This, if so, can help little to a knowl-
edge of their proper vowel character, which remains the same
under every variety of pitch. Is the peculiar character of each
vowel to be explained as a certain combination of harmonie
notes? This, if so, will not help much, in our physiological i a
quiries, till we have a better understanding of the mechanic
conditions upon which such combinations depend in other cases.

rof. Max Miiller, in reporting the discoveries of Helmholtz on
this point, tells us the vowel quality is to be explained as exactly
analogous to the timbre by which instruments, as the violin,
flute, ‘harp, &e., are distinguished one ares another. (Lect. on
the Sci. of Lan ng., 2nd ser., pp. 127-8: Am.ed.) But we have
voices differing in timbre,—the reedy — the flute-like bbe aac

upon their merits or bearing. They ru non a different line of
inquiry from that which I ‘have here in hand, and neither su-
persede it nor interfere with it

tered on every pitch with equal purity of tone, and there would
seem to be one certain key for each, on which the purest tone is
heard,—the purest musically we mean, that is, the most free
from discordant intermixture. The same cause above mentioned
may have an agency in this case also; but I think that here
the effect may be due primarily to the form and dimensions of
the vowel-tube.

Physiological Analysis of the Vowel Elements.

I. THe a VoweEts.—For these, the place of articulation is
between the root of the tongue and the extremity of the soft-
palate, that is, at the throat. That no part of the tongue but
the root is essentially concerned in the articulation, may be
easily ascertained: for the tongue can be variously rolled and
a without materially marring the vowel sound. The

tongue may lie loose upon the floor of the ribet except that
the whole will sepsis so participate in the movement of the
root portion as to be somewhat raised in the close vowel.
There are no labiale i in this group.

Degree1.— Vowel a'. This, the quite es vowel of the group,
is proper in such words as ‘staff, graft, ask, last, chant.
(Princ. of peri + 990, 6.) Itis the slodah i a in sa Pretielt as in la,

a strong tendency to pass into d° (cat),—the natu-
ral position ret the tongue and also that of the soft-palate being
nearly the same for both, —but the two sounds are to be clearly
discriminated.

2.— Vowel a?. The proper Italian a, and the ordinary

a in Pieuch, as établir, malade. In English, the Italian a, as we

call it, in father, arm, &e., is variously heard, but this form is to
regarded as the more elegant i in most cases

Degree 3.— Vowel a*. The open or broad a in French, as éme,*
bas, erdee, ee when under the circumflex.

—Vowel a*. The open French a may by some be
at ate in this form, that is, with the utmost depression of
the root of the tongue. So, also, the broad Low German a, an
the Scotch broad a, in man, &c., ‘though more commonly as 4‘.

In English, the @ may sometimes be ee saps; thus

II. Toe & Vowers.—The poktarigk fee “of the tongue is.
somewhat raised and is adjusted on each side to the lower por-
tion of the soft-palate to form the vowel-tube, which thus extends
upward and forward a little way from the throat, and directs the
vowel current obliquely upward. In this condition of the back-
tongue, the tip and fore part will be naturally retracted, and
more or less so as the vowel is more or less close.

belong to the @ group, but, to which degree, wig opportunities
have not been such as to enable me to determin

It is to be remarked that the open-depressed degree suits in all
cases with long quantity, and thus, in every group except. the
first (a), is liable to appear as a substitute for the close degree,
weet is naturally long in all but the first group, while the

mply open degree (No. 3) is, with the same exception, the one
fea of all fitted for ee quantity

Ill. THe o VowrELs.—The palato- -lingual passage is extended
one step further, to a higher point along the velum palati; and,
in direction, is inclined still more highly upward; the velum
palati itself is higher and more arched. As the back- jonas is
thus raised, the fore-part will vet rise also, Like a
the preceding group, the tongue will naturally be erased

more or less according to the degree of closeness.

The close and open or middle o correspond to the long and
short o in most of the languages of Europe; thus we have 0
close and long in our note, open and short in not. There is,
however, in the Italian and some other tongues, especially the
Danish and wedish, a distinction of so-called open and close
not identical with this ; and to confound that with this would

e a serious mistake. ‘The Italian close o (o chiuso, stretto) is
described by Dietz, A. J. Ellis, and others, as nearer to the w
(rude, full). The Italian open 0, Ss gio largo,) probably lies a
little on the other side of our o and nearer to the d. The dis-
tinction, which holds alike in the long a the short vowels—
croce, bocea (close), modo, dotto (open), —is at this day a nicety
of pronunciation not generally recognized or regarded except in
the purest style of the language as spoken by native Italians.

Degree 1.— Vowel 0%. Note, old, over, &c., that is, the “long 0”;
French, tréne, dter, repos, clos, dé épéat, pivot, au, eau, Ke. ; ‘Ger-
man, Ofen, lobt, Mond, &e.

The English "long o” is almost always diphthongal, or com-
pound, taking a vanish in another vowel, which is commonly of
the w group (full, food); as plainly appears in hoe, bow, no, bowl,
owe, low, &c. Followed by r, as in board, store, gore, oar, roar,
the vanish is a labial vowel of the d é group (but, err, Fr. eu).

labial modification: one of the affectations of some public speak-
ers. It might possibly be identified as an Irish or Scottish peeu-
liarity, or both. ,

egree 2.— Vowel o?', Heard in syllables which take a sort of
secondary accent, as opinion, cotemporary, agony, mulatto, mel-
low, propose, proceed. And in a considerable number of words,
such as stone, coat, toad, loaf, &c., the best taste will, perhaps,
prefer this to the extreme close 0, not neglecting, however, some-
thing of the vanish ; also in torn, lorn, board, door, &e.

Ve have here the shorter o in French, as obéir, noble, &c.
The German short o may, as I think, fall sometimes here an
sometimes in the third or open degree.

owelo?. An extremely improper pronunciation of a class
of words just alluded to, coat, stone, toad, throat, whole, loaf,
&c., quite common in America, and more especially in the rustic
dialect of New England. The fault is commonly described as
consisting simply in the omission of the vanish (Prine. of Pron.,
$20), but the non-labial character and the more open degree
are in fact equally essential. Board, door, oar, torn, are
also frequently and faultily so pronounced.

egree 3.— Vowel o?. Not, dot, hop, &c., which with those un-
der a? (nor, off, sod, &c.,) are the “short o” in English. The
distinction between o* and @%, though slight and usually not
regarded by orthoépists, is actually existent in practice, but
depends mostly, we believe, on the influence of consonants
associated.

Here, I think, belongs the shortest German 0, Gott, Ross,
flott; as also the French, sotte, culotte, folle, &c.

egree 4.— Vowel o*. Differs not greatly, but I think apprecia-
bly, from the d*. Here belongs, if I mistake not, the French
encore, corps, alors, aurore. We hear it in one of the several
mispronunciations of beard, ear, torn, forth, &c.

IV. Tae w Voweis.—The palato-lingual passage reaches
another step forward on the tongue, and to a higher point upon
the soft-palate; the vocal current is nearly vertical in direction,
and the soft-palate is arched upward extremely: the group
stands as the terminus of an ascending series from the throat. :

n this group, the tongue, in passing from open to close, is
perceived to be distinctly elevated as well as retracted.

Degree 1.— Vowel ut. The closer and usually longer oo, as
food, &c.; the o in do, &c.; oe in shoe, &c.; ou in you, &.; the
main and final part of the compound in wnion, view, few, eres
&c. Whether the u in rude, ruin, &c., should take a slight
initial sound of another vowel, is made a matter of question.
I think it strikes, or should do so, a more open vowel of the
group, and then falls upon this; as it does also in dew, new, 4
tube, lure, suit, &e. : .

182 S. Porter on the Vowel Elements in Speech.

This is the long wv vowel of most European languages. In
French, it is the long ow; the letter u, as alone, having early
gone over from this to a vowel group further forward.

The labial contraction is closer in this vowel than in the close
o. ‘lhe vowel bas a peculiar mellow smoothness, and imparts
the same character to the 0, when added thereto as a vanish. It
is possible to utter the palato-lingual part of this vowel without
the labial modification, but not smoothly and with perfectly pure
vowel quality.

Degree 2.— Vowel u?', Full, push, bosom, should, good, foot, &c.
In the proper pronunciation of these words, the lips are con-
tracted to nearly or quite the same degree as for the close o
simple. It is the final element in the diphthong our, now,
round, and the usual vanish of woe, low, roll, &c., the long 0.
In French, we have it in coup, bout, bourse, &c., that is, the
shorter ou. Itis the short or middle u of the German and of
most of the languages of Europe.

_ Vowel u?. This non-labial is frequently used in America,
improperly, in place of each of the two preceding, as in foot,
soot, root, roof, soon, book, shoot, full, put. If I mistake not, it is
the proper form of the shortest u in German, as in durch, &e.

egree 3.— Vowel u*. The unaccented fulfill, willful, &c.; also,
to, do, &e., when uneniphatic and somewhat slurred; also for-
merly common and still to be heard in New England in some,
if not all, of the class of words just specified, foot, soon, &c.
Young misses who mince their words will pronounce two, as
well as too, in this way. But slight change in the action of the
organs is needed to convert this utterance into either a short?
or a French wu.

Degree 4.— Vowel u*. Heard, as I incline to think, in the
Scotch gude or guid, sune, suld, blude or bluid, dure, &c. (for
goad, soon, should, blood, door, &c.), with perhaps a vanish in an-

new, tube, lute, &c. (Prine. of Pron., § 30.

‘ E 6 Vowets.—The palato-lingual tube reaches yet
further forward, but hardly beyond the extreme fore-part of the
soft palate. ‘he edges of the tongue join the borders of the
palate about «s far as to the hinder teeth, and the tip of the
tongue is naturally further forward than in the more close of the
degrees in the preceding group.

In this and in all the remaining groups, the degrees of close
and open are made by the greater and less elevation or depres
sion of the tongue, and not at all by its retraction.

diphthongs, viz., ow or ow (our, now), and long? (zce, kite), ac-

I give this as the precise arrangement which brings out the
sinnd most distinctly and most naturally. But, im all the ante-
rior groups, as before remarked, owing to the extensile structure
of the tongue, the articulation may have a determinate and
nearly invariable place upon the palate, and yet reach to a vari-
able point on the tongue. Thus, in this case, the tongue may
be thrust forward, with the tip and fore part depressed behind
the lower teeth; the terminus of the vowel-tube falling further

, of course.” The variation is the same as may occur in
the so-called ii consonants, ¢,n, d, which are properly made
with the tip of the tongue, but can be uttered by using a part
of the tongue considerably further back.

The peculiar shape of the palatal arch, as it converges forward
and gives to the passage a rounded form, would seem to bear an
essential part in producing the vowels ‘of this group. If they
can be imperfectly imitated at a place further back on the palate,

Experiments of this sort, fairly made, seem to me to furnish
complete demonstration of the leading principles on which I
insist. Further proof will appear in the sequel.

Tf, on the other hand, we try to arrange all the vowels in a
single series on any principle whatever, we find ourselves ut-
terly baffled. If we distinguish them as simply more and less
open or close, we find confusion instead of order. Nor should
these terms open and close be applied otherwise than as I have
done. It is true they might not unaptly be used to describe the
difference as the vowel station moves back toward the throat or
forward from it,—even as they might describe the corolla of a
flower unfolded down toward the base or only near the tip,—
but the terms are wanted to indicate the width of the expansion,
and must therefore not be used for the depth. Neither is the
confusion escaped by setting the labials in a class by themselves,
arranged according to the extent of the labial opening: the
labials cannot be all so discriminated, if we include all in actual
use, while for the non-labials the difficulty still holds. Nor will
any other subdivision answer, which falls short of the group-
ings, or substantially such, as in the scheme here presented.

Art. XXVI.—On Photo-micrography with the highest powers, as
practised in the Army Medical Museum; by J. J. Woopwarp,
M.D., Asst. Surgeon and Brevet Major U.S. Army, in charge
of the Record and Pension Division Surgeon General’s Office,
and of the Medical Section Army Medical Museum.

PHotocRrapPHy had but just begun to attract attention when
the attempt was made by Donné to reproduce microscopic objects
by the Daguerrean process; and although the results of these ex-
periments were far from satisfactory, they promised enough to lead
to further efforts in this direction, renewed with each step in the
gradual improvement of the photographic art. These exertions
were crowned by acontinual progress, which did not however
keep pace with the development of other branches of photogra-
phy, though it must be admitted that in the hands of the more
modern experimenters, and especially of Prof. Gerlach of Erlan-
gen, Jos. Albert of Munich and Dr. R. L. Maddox of Southamp-
ton, the success has been such as to guarantee a wide field of

usefulness for this method of representation.

In America, the chief experimenters have been Prof.
Rood of Columbia College and Mr. Lewis M. Rutherfurd of

York. Besides these, mention must be made of the paper of Dr.
John Dean of Boston on the Spinal Cord, which is illustrated by
photomicrographs reproduced by photolithography. The work
of D n however was done with magnifying powers not ex-
ceeding ten or twelve diameters, while both Professor Rood and
Mr. Rutherfurd have experimented with very high powers.
Prof. Rood published a very interesting account of his process
in this Journal in 1861.’ Omitting details, it appears from this
paper that in his operations, he used direct sunlight for illumina-
tion, and employed ordinary achromatic objectives with or without
eye-pieces. The difference between the visual and chemical foci
he endeavored to overcome by an alteration of the fine adjustment
after the plan suggested by Shadbolt.? Prof. Rood thus obtain-

achromatic objectives. In May, 1865, Mr. Lewis M. Rutherfurd,
New York, published a paper on Astronomical Photography,’
which contained the following suggestive passages. “T

vergence. On applying this test I found that an objective of flint
and crown in which the visual was united with the photographic
focus, (in other words, where the instrument sala be focalized
on a plate of ground glass by the eye, as in ordinary cameras,
and in the heliographs constructed by Dalmayer for the Kew
observatory and for the Russian government,) is a mere com-

romise to convenience in which both visual and actinic qual-
ities are sacrificed. ”

crown lens should be combined with a flint which will pro-
duce a combined focal length about one-tenth shorter than would
be required to satisfy the conditions of achromatism for the eye,
and in this condition the objective is entirely worthless for vis-
ion.” With a telescopic objective constructed on this principle,
Mr. Rutherfurd obtained telescopic photographs of such satisfac-
tory quality that he concludes his paper as follows:

“The success of this telescopic objective has encouraged me
to hope that an almost equal improvement may be made for
photography in the microscope, which instrument is more favor-
ably situated for definition than the telescope, since it is inde-
pendent of atmospheric conditions, Its achromatic status is
easily examined by the spectroscope, using as a star the solar
image reflected from a minute globule of mercury. Mr. Wales
is now constructing for me a one-tenth objective, which, upon
his new plan, is to be provided with a tube so arranged as to ad-
mit the removal of the rear combination, and in place of the one
ordinarily used, one is to be substituted at will which shall
bring to one focus the actinic rays.”

This objective was satisfactorily constructed by Mr. Wales (of
Fort Lee, N. J.) and Mr. Rutherfurd made with it a number of
experiments, full of promise, though his other pursuits prevented
him from following out the new plan to its ultimate results,

Such was the condition of photo-micrography in America

done in this direction. This is also the opinion of Dr. lox,
whose judgment is of the greater value as he is one of the most
successful laborers in this direction in Europe, ;

192 J, J. Woodward on Photo-micrography.

The principles involved in obtaining successful photographs
with the microscope are the following:

1. 'To use objectives so corrected as to bring the actinic ray
to a focus.

2. To illuminate by direct sunlight passed through a solution
of ammonio-sulphate of copper, which excludes practically all
but the actinic extremity of the spectrum.

3. Where it is desired to increase the power of any objective,
to use a properly constructed achromatic concave instead of an
eye-piece.

4. To focus on plate glass with a focusing glass, instead of
ground glass.

5. With high powers to use a heliostat to preserve steady
illumination.

. Where an object exhibits interference phenomena when
illuminated with parallel rays, as is the case with certain diatoms
and many of the soft tissues, to produce a proper diffusion of
the rays by interposition of one or more plates of ground glass
in the illuminating pencil.

Strict adherence to these principles is indispensable to success.

rts about the stage and objective of the microscope, and thus
prevents the leakage of light into the room.

The plate holder is movable backward and forward on the
walnut frame on which the microscope stands, its maximum dis-
tance from the stage of the microscope being nearly nine feet.

To permit ready focusing at distances greater than the length
of the arm, a wooden rod #ths of an inch in diameter and capa-
ble of easy rotation runs the whole length of the right side of the
frame. ‘The milled head of the fine adjustment of the microscope
is grooved, and a small grooved wheel in the end of the rod
permits the two to be connected with a band. The operator
standing at any part of the frame can therefore manipulate the
fine adjustment by simply turning the wooden rod in his fingers.

The arrangements of light, position of object, coarse adjust-
ment, &c., are made by the operator, who stands by the micro-
scope, which has a suitable eye-piece adjusted, and observes the
object in the usual way; afterwards, removing the eye-piece
and going to the plate holder, the final focusing is made by
means of the wooden rod, the image being viewed with a focus-
ing glass on a piece of plate glass held in the same frame which
is to receive the sensitive plate.

he cell containing the ammonio-sulphate of copper hangs
outside the shutter over the hole by which light is admitted.
It not only excludes the unnecessary illuminating rays, but pre-
vents danger to the objective from the concentrated solar heat
and permits the eye of the operator to view the objects about
to be copied without fatigue or injury. Latterly a plate of alum
has also been used to exclude solar heat especially during any
temporary removal of the ammonio-sulphate cell. The chemical
processes employed are well known to all photographers. With
the above apparatus, it has been found that the best defined
pictures are obtained when the distance employed with any ob-
jective does not exceed three or four fee é

It was intended to obtain with this the same power as with the

At the date of publication of Circular No. 6, Surgeon Gene-
ral’s Office, both Dr. Curtis and myself believed these markings
to be hexagonal, as was stated and figured on page 148 of that
work. The greater power now obtained has corrected this opin-
ion, but it is worthy of note that in the present pictures the
markings appear hexagonal in both the small ones, if viewed
with the eye at the visual distance, while on close inspection or
with a lens they are seen to be circular. In the pictures with
19,050 diameters the circular shape of the markings is very plain,

t if viewed from a considerable distance or with a concave
lens, they appear hexagonal. I also send you herewith a photo-

THE mineral spring, the water of which is the subject of this
notice, is situated in the town of Barton, Tioga Co., New York,
about seven miles northeast of the village of Waverly, near
what is called Talmadge Hill. It is one of two sulphur springs
that have been observed in that county. The other, resembling
it in character, is about twenty miles north, near the village of
Spencer; both have been noticed in the State geological reports,
and have been in repute for many years among the inhabitants of
that region on account of certain remedial properties which their

weeks, gave a slightly larger amount, which resulted from oxyda-

of Silver; by M. Carey Lea, Philadelphia.’

Muc# difference = ra teak has long existed in respect to the
explanation of certain phenomena of photographic action. In
the vast majority of eases the action of light is a reducing one.
Salts of iron, of uranium, and of other metals are reduced from
a higher to a lower stage of oxydation, and the same is the case
with the combinations of certain metallic acids, such as bichro-
mates and ee These phenomena present n o difficulty.

in the presence of free nitrate, is carefully washed, the free ni-

it does not do, but leaves behind yellow iodid of silver perfectly

found the same to be the case when tan zn is subsite
for free nitrate of silver, though the actibd’ is areniy slower:

in the former case a sub-iodid is formed.

There is a question, however, far more difficult than these, to
answer, and it is this: Does reduction of some sort invaria ly
accompany the action of light upon iodid of silver? Is, or is
not that action, in its essence a chemical action

Before proceeding to investigate that question, another pre-
sents itself, demanding solution. It had been long held as an
indisputable fact, which none had attempted to controvert, that
perfectly pure iodid of silver was insensitive to light, and that
sensitiveness only a peared when free nitrate of silver, tannic

The second . oct ee . generally admitted; th

briefly state thie. pect of the saenedl series of investigations
undertaken to arrive at a clearer view of the principles involved.

When pure iodid of silver, isolated, is exposed to light for a

If the action of light in producing an invisible image upon
pure iodid of silver isolated be a chemical] one, it is not possible
that it should be destroyed except by chemical means.

A piece of glass supporting a film of pure iodid of silver iso-
lated from all other substances was exposed for many hours to
a strong sunlight. It was then placed in a dark closet for
thirty- me hours, at the end of which time it was placed under a
negative and e exposed to light for two seconds. On pouring a
ccanrette over it, a clear “bright picture instantly appeared.

image. This very remarkable fact, a description of which I
nape ate early in June last, and which has been since verified

y other observers,* might seem to be inimical to the physical
theory. A careful study proved the contrary. Pure iodid o
silver, still moist, in considerable quantity, freshly precipitated
and washed, was placed in a porcelain basin and exposed to sun-
light. It instantly showed the slight darkening above referred
to, but even after the action of the light and direct sunlight was
continued for several hours, no reduced silver could be detected.

In addition to the foregoing, which are direct arguments, is
to be placed the following indirect.

Chemists are very familiar with the fact that in cases of slow
precipitation, the precipitate tends to follow the path which the
sed to stir the solution, has travelled over. The anal-
ogy which this and the development of a latent image present
cannot be missed, and they are brought closer still by the pres-
sure images just described. In all cases a molecular alteration
takes place, and the molecules thus altered seem to have their
attraction for exterior objects increased, and for each other and
tbe surrounding homologous particles diminished.

This has been beautifully illustrated by some experiments
lately published. A steel burnisher being drawn firmly over @
plate of glass, yet so as not to scratch it or abrade the surface,
the glass on examination by polarized light showed its structure
altered by a line of color where the burnisher passed. This
molecular effect slowly diminishes, and in a few days the parti-
eles return to their wonted state.

The foregoing experiment beautifully illustrates the changes
of molecular condition whic ies are capable of undergoing.
I have just remarked, that by drawing a blunt glass rod over the
inside of a glass vessel, the parts so treated attract to themselves

of a latent photographic image, and the experiment just cited,
reveals by polarized light a change of structure in those paths
over which the body has been drawn. In the course of hours
or days, this molecular change gradually passes away, and the
_ body recovers its original condition, just as ave shown that
when as in the case of pure iodid of silver, isolated, no reduction
takes place, the effect of light gradually passes off, leaving the
iodid free to receive a new impression.

It seems almost superfluous to say that what is here stated of
_ the development of pressure images is not given by way of ex-
planation, but as illustration and confirmation of the general
view expressed.

Before concluding, a few words seem required as to what ex-
= is to be given to the ordinary process of Negative

graphy.
In the foregoing I have reasoned on the action of light upon

pure iodid of silver isolated. In the camera, light is made to

act upon lodid of silver in a very different condition. It is in
contact with nitrate of silver and with organic matter, and here

I think it is evident from what has been already said, that in
this case several images are formed, superposed as it were, on eac
other,—First, a physical image upon the iodid of silver. Sec-
ondly, if the exposure be sufficient, an image formed of sub-iodid
of silver produced by the action of light upon the iodid and ni-
trate. Thirdly, there may be an image formed by the action of
light upon the silver or its iodid in connection with the organic
matter of the film (collodion or albumen). And, fourthly, if
bromid or chlorid be present in the film, these may undergo
reduction.

The separate nature of these images, or some of them, which

merated, was completely removed. Nothing remained but the
third, and it is not improbable that in some of the “dry pro-
cesses” this third source is the principal basis of the picture,
though evidently only a subsidiary one, in the ordinary “ wet
process.”
Another form of this experiment consists in developing the
picture Jefore immersing it in the solution of acid nitrate, and
then in leaving it but a short time in that solution, so that only
the visible picture shall be removed, and the film of iodid and
bromid be left. a
Here all basis for development depending upon reduction is
removed, and the production of the picture must depend wholly
upon the first and third of the foregoing causes to the exclusion:
of the second and fourth.

Without having extended my observations to the reo
type, I may remark that this process must be ranked along with
those in which there is a reducing substance present, and there-
fore reduction may take place. The metallic back of the da-
guerreotype plate stands in the same relation to the iodid that
tannin and other so-called sensitizers do. It seems probable
therefore that in the case of the daguerreotype, there may be

alls, imposes no more difficulty than the dissimilarity of the
nature of the glass from that of the precipitate which is attached
to those parts of the glass which have been pressed by the rod
in stirring.

In fact it may be truly said that whenever one body is pressed
against another, the particles of the body pressed against tend
to have their attraction for each other diminished, and their at-
traction for external bodies, whether homogeneous or heteroge-
neous, increased.

I have endeavored in this brief review of a subject replete
with difficulties, to show that the action of light upon pure iodid
of silver isolated cannot be a chemical reduction:

1st. Because that effect, even when carried many hundred
thousand times further than in the ordinary ott Ba pro
cesses, perfectly disappears in a few hours, spontaneously, under
circumstances which render it impossible to suppose that jodine

have been restored to replace that which (had reduction
taken place) must have been disengaged.

. Because, even where the action of light is prolonged many
hundred thousand fold the ordinary time, no reduced silver nor
sub-iodid can be detected as present.

3d. I have shown that another metal, mercury, is capable of

sil

developing these images as well as silver.

and the Rocky Mountains, could a mountain chain have been roduced,
because the accumulated materials were insufficient. The Rocky Moun

tains owe their greater height to a series of later deposits than ri:
3 which cap the Appalachians; the White Mountains are covered with a
3 later formation than that which covers the Green Mountains; the Alps
are newer than the Jura; and, generally, if it is the original deposition
of the materials that has pro uced mountains, then the greater the accu-

the long-continued accumulation of sediments; sediments not simply
marking this altitude, but vastly more, for there is doubtless as much oj
the mass below the level of the sea as above it. This view we find a
plicable to the Appalachians, and it must be a necessary condition of
mountain elevation.” ——Hall’s Pal. N.Y., Vol. LII, Introduction.
“We must look to some eae _— than heat for the production of
the phenomena [of metamorphism]; and it seems that the prime cause
must have existed within tha material itself, and that the entire change
is due to motion, or fermentation, and pressure, aided by a moderate in-

a level where the surrounding temperature was higher.—

The hypothesis then is that the thickening of the deposits

went on through the Paleozoic ages (and which was due mainly,
as Mr. Hall holds, to material distributed e the northeastern
Oceanic current, now she co abrador current) ultimated in a
subsidence of 40, 000 feet, and in flexures, plications, fractures, —

Hall. And it must be admitted, further, that in other regions
of the globe subsidence has, in most cases, attended similar
accumulations. We do not question this postulate of Mr. Hall’s.
The Carboniferous formation of Nova Scotia is a case o
kind where the evidence is clear; for although 16,000 feet thick,
it bears throughout proofs of its origin near the ocean’s level,
in dirt beds, coal seams, estuary deposits, and the like. The

mately, of gradually progressing subsidence.

sediments? Could there be the foot-per-foot movement under
any degree of thinness? Surely the 800 miles of the mathema-
ticians, or the densely viscid or the solid interior of some theorists,
would give it no chance. And would a thickness of twenty

ticularly near the outcrops of the Onondaga shales, or at the ter
mination of their surface drainage, are frequently found to be
filled with an abundance of water of a peculiar saline character.
ese waters sometimes contain only mere traces of chlorids,
while in those from other similar localities in their vicinity a
considerable amount of chlorid of sodium may be observed.

Among the questions to which these facts give rise, the fol-
lowing appeared to me of great interest:

First: Xs there any relation between the chemical composition
of the spring waters peculiar to the locality, and the brines?

Second: What chemical changes may result from their union,
should their composition materially differ.

Third: Do the waters of the springs and the brines derive their
characteristic qualities from soilor rocks of one and the same
kind, though in different conditions; or do they both owe their
peculiar chemical composition to entirely different sources; and
if so, where are these sources located ?

In entering upon considerations of the above questions I se-

the brine-bearing district, two in its immediate vicinity and a
sample of average brine of the Syracuse district.

The samples were as follows:

of pseudomorphs of chlorid of sodium had been found; the well
terminated in a hard clayish shale.

Two prominent hills, of which the most conspicuous is known
as “Prospect Hill,” intervene between that locality and the quite
abrupt descent of the high grounds around the east and south-
west side of the former lake bed—our present brine-furnishing

of crumbled green shale, and lastly twenty-five feet of a har

grams or 51°9849 grains.

b. Water taken from a well sunk from the top of Prospect
Hill, to a depth of seventy-five feet, i. e., the level of Salina street
at the corner of Lock street. Prospect Hill lies about midway
between the well which furnished the water for Analysis a, and
the northwestern termination of the high embankment (80 or
40 feet) around the eastern and southeastern shores of Ononda-
ga Lake and its adjoining low lands. Prospect Hill consists
mainly of gravel and is covered with numerous boulders, and
underlaid with the red clay of the Onondaga Salt Group. The
gravel is here and there interspersed with layers of cemented
gravel (hard pan) and of a red loamy soil. These layers are of
varying extent and apparently without any order of succession.
The water subjected to analysis was taken from the first quanti-
ties drawn from the well soon after its completion (April, 1868).
Quantitative tests for carbonic acid and iron, being under exist-
ing circumstances of no value, were omitted.

Although, unquestionably, much significance must be conceded
to the fact that the same group of elements form the most prom-
inent features of the analytical results, there nevertheless exis-
ted some doubts whether a mere succession of extractions of the

plain satisfactorily the peculiar nature of the various liquids ;

I. How does carbonate of magnesia act yin sulphate of lime in
the presence of free carbonic acid ?—To test the degree of this ac-
tion, I adopted the ipl course. T mixed in a suitable
vessel ten grams of well washed carbonate of magnesia, twenty-
five grams of sulphate of jeer (gypsum,) and five hundred
cubic centimeters of distilled water : which mixture I afterwards
treated for a short time each day during four weeks, with well
washed carbonic acid gas, soas to secure a constant supply of
bicarbonate of magnesia to the solution of gypsum. The solu-
tion thence resulting, after being separated by filtration from
the white residue, was equal to four hundred and fifty cubic
centimeters. I place ced it in a flat glass dish, and left it to grad-
ual Phd aecpae at the ordinary temperature.
few days rest the bottom of the vessel began to be
covered with a small amount of sediment. No further note-
worthy change took place, until the whole liquid gradually
formed into a solid crystalline mass, consisting in the main of a
net-work of needles. The solution, being tested before its so-
lidification, was of a slightly alkaline reaction; the crystals re-

Art. XXXIII.—On Gay-Lussite from Nevada Territory ; by
B. SILLIMAN. |

In September, 1864, I “ipnas the body of saline water known as
Little Salt Lake, situated near Ragtown, about a mile and a half
south of the main emigrant dea to Humboldt. It fills the bot-
tom of a deep funnel-shaped depression in the Desert plain. The
form and other peculiarities of this depression suggest a volcanic
origin. It is distinctly crater-shaped, with the outline a double
ellipse, made apparently ia the “aoe of two craters; the
larger is to the north, an sa diameter of about a mile and a
half. The whole length paid and hs is somewhat greater than °
that from east to west in the larger division. The water- surface
is about 200 feet below the lip of the crater, mebie is elevated
somewhat above the general level of the plain. The slope of
the converging sides is steep, varying from 25° to 45°; the ap-
proach to the water is therefore difficult, except at one or two
points where an oblique footpath has been worn. There is a
narrow margin or beach, varying from a few yards to a hundred
feet or so, covered with shoal water, and the shore then plunges’
off to v eep water. There is a small island in the northern
or large division of this lake, also surrounded by shoal water.
The section of the slope shows a series of beds of volcanic ma-
terials, lapilli and ashes, mixed with boulders or masses of black

t, and concretions from thermal springs. The shores on
the west side are also skirted with calcareous matter, and there
is a steady flow of water from numerous small springs of fresh
water into the lake. One of these springs is a copious fountain
of excellent drinking water. The water of the lake is very
saline. Its taste is salt, bitter, and decidedly alkaline. Its
effect on the skin in bathing i is that of a solution oe an alkaline
carbonate, and its odor is strongly marine. The $ are en-
epee with saline matters resulting from the scaporstion of

near the shore were not dense enough to deposit these crystals;
and that if we could reach the island we might find them there,
where, from the absence of fresh water springs, the saline solu-
tion of the lake would be more dense. This conjecture was
fully verified. Mr. Semple, my secretary, succeeded in reaching
the island in a very insecure boat, where he found the shores
completely incrusted with beautiful clusters of these crystals,
whose acute edges cut the naked feet. We secured an abundant
supply of this rare and interesting mineral which, I believe, had
not before been recognized in the United States. No other crys-
tallized mineral was discovered.

e Gay-Lussite obviously has its origin from the reaction of
the salts of soda and lime with which the waters are abundantly
charged, and being very slightly soluble is readily deposited in
these situations where the density of the water is maintained or
increased by solar evaporation.’ Hence it does not occur along
the shores where the marginal springs of fresh water dilute the
solution. The flow of these springs does not in summer fully
replace the solar evaporation, as is evident from the water-line
retiring slightly from its winter level.

_ This interesting lake has no outlet. It has plainly been a
point of volcanic activity in modern geologic times, its eruptions
being confined to mud, ashes, pumice and lapilli. It is one of a
considerable number of similar phenomena with whic reat
Basin is dotted, and of which Mono lake, on the western margin
of the Desert, is the most remarkable. The bottom of the an-

THE crystals of Gay-Lussite here described were obtained by
Prof. B. Silliman in 1864, at Little Salt Lake, near Ragtown,
Churchill Co., Nevada. The crystals differ strikingly from
thosé measured and described by Phillips (Phil. Mag. April,
1827) in the proportional development of the planes as is shown
by comparison with the figures given by Phillips, and by Des-
cloizeaux (Ann. Ch. Phys., 8d series, vol. vii, p. 489).

* Gay-Lussite has been made artificially by J. Fritzsche, by mixing eight parts
by measure of a saturated solution of carbonate of soda with one of a solution of _

224 H. J. Clark on Anthophysa Miillert.

A considerable portion of the second volume of the great
work of Messrs. Claparéde and Lachman, ‘“ Etudes sur Jes Infu-
soires,” &c., is occupied by a discussion of the animality of cer-
tain doubtful forms of Monad-like infusoria. The tests which
these authors offer as determinatives of the zodlogical relations

decided it to be a genuine animal, The figures of Cohn (Mikro-
skopische Algen und Pilze. Nov. Acta Acad. Cs, Leop, 185+.
Taf. xv, fig. 1-8) are not much better than those of Dujardin.

Habitat and general appearance.—I have been so fortunate as
to determine the animality of Anthophysa by both of the tests
above mentioned; and there rests not the least doubt in my
mind that this infusorian is as truly a member of the zodlogical
kingdom as any of the well known Protozoa. I would state,
for the information of those who are not acquainted with the
habits of this animalcule, that it is quite common among the
fresh water weeds. It may be most advantageously studied
when it is attached to Myriophyllum or Ceratophyllum ; a small
piece of the tip of the filiform leaf, of either, which seems to be
covered by an irregular, floccose deposit, usually affording abun-
dant specimens.

Under a low magnifying power this floccose matter appears
to consist of clusters of very jagged, irregularly branching and
contorted, semitransparent, intertwined stems and projecting,
tapering and flexible twigs. ach of the tips of the latter sus-
tains a single, more or less globose mass of spindle-shaped bod-
ies, which radiate from a common center of attachment; and
are kept in a constant agitation by the spasmodic jerks of a
long, stout, usually rigid, areuate filament, with which the free
end of each one is endowed. The whole bristling mass revolves
alternately from right te left and from left to right; whirling
upon its slender pivot with such a degree of freedom that one
might almost suspect that it merely rested upon it, and had no
truer adhesion to it than the juggler’s top to the end of the

ends and the twig begins. All of the members of a group ra-
diate from a common point of attachment, to which they adhere
by their tapering filamentous ends. The free end is truncate,
but one corner of it,—as if in continuation of the line along
which the opposite flattened sides meet,—projects in the form
of a rather blunt triangular beak. At the inner edge of the

ase of this beak lies the mouth, to which the former—as fre-
quent observation has proved—acts as a lip or prehensile organ
when food is taken into the body. The prevailing tint is a more
or less uniform light gamboge, without the least trace of an eye-
Spot of any color.

always toward the pedicel of the colony. One is forcibly re-
minded by this of the systematic relation of some of the flowers
of Labiate, with their stamens projecting far beyond the upper
lip of the corolla. The globose heads of the Menthe are partic-
ularly good examples for illustrating this similitude.

cule possesses are preéminently prehensile in character; and
their apparent appropriation for the office of propulsion, when a
colony breaks loose from its attachment, I can scarcely doubt is
an accidental one, inasmuch as the arcuate cilium continues its

usual mode of action.

then the cilia return to their usual positions, while the intro-
cepted edible passes toward the center of the body, and is there
immediately enclosed in a digestive vacuole. For a while the
food dances about in this vacuole with a very lively motion, but
finally it subsides into quietude. ses

The contractile vesicle.—There is a two-fold difficulty in discov-
ering the presence of this organ. In the first place it is compar-

very rarely possible to see it contract twice in succession be-
tween any two of the abrupt, lateral deviations of the body,

about half way between the two ends of the body, and nearly
midway betwixt the two extremes of its greater dia

youngest, terminal portions of the branches which, under the
name of twigs, have been dieneibid in this paper as the imme-
diate supporters of the colonies of monads, are evidently tubu-
lar. They appear to be as flexible as a spider’ s thread, and are
usually quite irregular in outline, and in the calibre of the canal
which permeates them. The wall of these tubular twigs is quite
thick, and is alike rough on the exterior and interior faces. The
substance within the tubes appears homogeneous, but whether
it is solid or fluid could not be determined. The oldest part of

idly separate from each other by the broadening of the body,
and leave between them the smaller cilium. The latter at this
time appears much thicker than usual, and seems to be composed
of two closely approximated, parallel threads. By this time the
contractile vesicle has also divided into two, which lie closely
side by side.
At this moment the time noted in one series of observations
30 P.M. By 2.35 p.m. the larger flagella had separated
still farther, and the smaller cilium had split into two very con-
spicuous filaments; as yet, however, attached to a common point
of the body. From this time forth to the completion of the
process of fissigemmation all of the cilia kept up a slow vibra-
tion, in which they undulated from base to tip with a sort of
snake-like motion. By 2.45 p.m. the body had become quite ap-

of constriction. Still the process went on very rapidly, and by
2.55 P.M. the new bodies were widely separated, but still attached
to each other by a mere thread. At 3 P.M. the body which was
attached to the pedicel was left alone, and its companion swam
away to seek a new attachment, and build up its stem.

To the last moment the hyaline envelope remained about the
Segments, and in fact so long afterwards that time and circum-
Stances did not allow me to ascertain its final disposition. EI
would remark, however, that when the ovate bodies of the half
grown monads are contracted temporarily into a globular shape,
they appear identical—excepting that they lack the hyaline en-
Velope—with these recently fissated forms. In all probability,
therefore, the latter lose their envelope and assume the shape of
rmer.

that it grows out from the posterior end of the body. The best
proof of this is that I have frequently found a monad—espe-
cially in the condition of the one which I described above as
breaking loose from its companion—nearly sessile upon a clean
spot, and attached by a very short, faint, film-like thread. From
this size upward I had no difficulty in finding abundant examples
as gradually increasing in diameter as they did in length; thus
furnishing a pretty strong evidence that the stem grows under
the influence of its own innate powers, and is not therefore a de-
posit emanating from the body of the monad, except, perbaps,
as it may be nourished py a fluid circulating within its
hollow core.

show how much more they might do so. IfI am not mistaken,

it will follow from the facts to which I shall allude, that our

1. The advantages of horticulture to botany.—Let us first men-

4 tion the services that horticulture renders, or may render, to

botany. Without being myself a horticulturist, I affirm or rec-

| @ ognize them willingly, the advancement of science rendering it
a necessary to have recourse to all its collateral branches.

studying the curious phenomena of fertilization, the movements
and direction of the stem, leaves, and parts of the flowers. Hor-
ticulture has done much to advance the progress of physiological
botany, but it still has much todo. The most remarkable ex-

race These have a great scientific importance, and
it is undoubtedly the horticulturists who are the teachers of

It app me, however, gardens can be made still more
useful in carrying out physiological researches. For instance,
there is much yet to be learne e mode of action of heat,

light, and electricity upon vegetation. I pointed out many of
these deficiencies in 1855, in my “Géographie Botanique Rai-
Ten years later Mr. Julius Sachs, in his recently pub-
lished and valuable work on physiological botany,’ remarks
much the same deficiencies, notwithstanding that some progress
has been made in these matters. The evil consists in this, that
when it is desired to observe the action of temperature, either
fixed or varied, mean or extreme, or the effect of light, it is ex-
ceedingly difficult, and sometimes impossible, when observations
are made in the usual manner, to eliminate the effects of the
ne variations of heat and light. In the laboratory it is

wished to ascertain the influence of the gases diffused in the at-
mosphere around plants, or that of the plants themselves upon
the atmosphere.

Place plants under a receiver, and they are no longer in a natu-
ral condition; leave them in the open air, and the winds and
currents, produced at each moment of the day by the temperature,
disperse the gaseous bodies in the atmosphere. Every one is
aware of the numerous discussions concerning the more or less
pernicious influence of the gases given off from certain manu-
factories. e ruin now of a manufacturer, now of a horticul-
turist, may result from the declaration of an expert; hence it is
incumbent on scientific men not to pronounce on these delicate
questions without substantial proof.

to the wish of the observer?” My question passed unnotice
in a voluminous work where, in truth, it was but an accessory.
I renew it now in the presence of an assembly admirably quali-
fied to solve it. I should like, were it possible, to have a green-
house placed in some large horticultural establishment or botanic
garden, under the direction of some ingenious and accurate
physiologist, and adapted to experiments on vegetable physiol-
ogy; and this is, within a little, my idea of such a construc-
tion ;—

The building should be sheltered from all external variations
of temperature; to effect which I imagine it shou e ina
great measure below the level of the ground. I would have it
built of thick brickwork, in the form of a vault. The upper
convexity, which would rise above the ground, should have two

The vaulted building should have an underground communica-

ge cl a series of successive doors,
The temperature should be regulated by metallic conductors,
heated or cooled at a distance. Engineers have already devised

ratus when necessary.

Obviously, with a hothouse thus constructed, the growth of
plants could be followed from their germination to the ripening
of their seeds, under the influence of a temperature and an
amount of light perfectly definite in intensity. It could then be
_ ascertained how heat acts during the successive phases from

coloring matter of flowers when it has been dissolved in water
or alcohol.“ Those rays called chemical, such as violet, and the
invisible rays beyond violet, according to recent experiments,
confirmatory of those of ancient authors—those of Sebastian
Poggioli, in 1817, and of C. M. Guillemin—have but one single
well-ascertained effect, that of favoring the bending of the stem
toward the quarter from which they come more decidedly than
do other rays; yet that is an effect perhaps more negative than
positive, if the flexure proceeds, as many still believe, from what
is going on on the side least exposed to the light.”*
effect upon vegetation of the non-visible calorific rays at
the other extremity of the spectrum have been but little studied.
According to the experiments we have on this subject, they
would appear to have but little power over any of the functions ;
but it would be worth while to investigate further the calorific
regions of the spectrum by employing Dr. Tyndall’s process,
that is, by means of iodine dissolved in bisulphid of carbon,
which permits no trace of visible light to pass.
How interesting it would be to make all these laboratory ex-

prolonged as long as desirable, and, probably, unlooked-for re-
sults would occur as to the form or color of the organs, particu-
larly of the leaves. :
Permit me to recall on this subject an experiment made in
1853 by Professor von Martius.” It will interest horticulturists
now that plants with colored foliage become more and more
fashionable. Prof. von Martius placed some plants of Amaranthus
tricolor for two months under glasses of various colors. Under

It is horticulture that has given us the longest series of illus- _

do justice especially to the English horticulturists. No doubt

to that of tea; and we can assert that that part of America in-
cluded between San Francisco and the Oregon territory will,
one day, supply wines as varied and as excellent as those Kuro-
pean ones produced between Portugal and the Rhine.

It is a singular fact, that the two principal beverages of the
civilized world, wine and tea, which produce similar stimulating
effects, but which to a certain extent are the substitutes one for
the other in different countries, present also in the mode of cul-
tivating them the most marked resemblances and differences.
The vine and the tea-plant succeed best on stony, barren hill-
sides, of which they sometimes increase the value a hundred-
fold. According to the exposure, the soil, the cultivation and
manner of preparing the produce, wine and tea are obtained of
unquestionable excellence; while the neighboring crops, but a
short distance off, may be more or less ordinary in quality. The
two shrubs require a temperate climate, but the vine needs heat

nd no rain during summer, while the tea-plant requires rain
and but little summer heat; the result of which is, that these
two species are almost geographically incompatible. Vine-grow-
ing countries will never produce tea, and vice versd.
ut you will say, these examples belong rather to agriculture,
‘and concern neither botany nor gardens. I maintain the con-

to the French colonies in America. A multitude of such in-
stances might be named. In the present day science has pro-
gressed, practical men avail themselves of it, governments and
nations have abandoned those mistaken ideas in accordance with
which it was supposed that a cultivation advantageous to one
country othe

was injurious to others. Hence we may hope to see,

252 J.D. Dana on the origin of the Earth’s Features.

Art. XL.—Appendix to Article XXX, On the Origin of some of
the Harth’s Features; by JAMES D. Dana.

On page 210 I have made but a bare allusion to the question
of the heat required in metamorphism. . Vose dispenses
with heat altogether, except what may be incidental to compres-
sion. And Professor Hall regards it as of secondary importance,
or not absolutely necessary (see our citation on page 207), and
attributes the little extraneous heat that may be present and
operative—probably, he says ‘‘ not much above that of boiling
water” (Pal., vol. iti, p. 77)—to the sinking of the thickening
deposits to a level ‘‘where the surrounding temperature was
higher ;” higher, that is, on the principle, first suggested by Her-
schel, of the rising of the isothermal planes within the earth’s
crust in concordance with increase of thickness through super-
ficial deposits; the isothermal plane of 100°, for example, being
within a certain distance of the surface of the crust in a given re-
gion, and rising as the surface rises by new accumulations above.

The correctness of Herschel’s principle cannot be doubted.
But the question of its actual agency in ordinary metamorphism
must be decided by an appeal to facts; and on this point I would
here present a few facts for consideration.

The numbers and boldness of the flexures in the rocks of most
metamorphic regions have always seemed to me to bear against
the view that the heat causing the change had ascended by the
very quiet method recognized in this theory. For the heat, thus
slowly creeping upward, a few inches, feet, or yards in a cen-
tury, should produce the change with little disturbance in the
mass, and leave the beds nearly or quite horizontal: a condition
very unlike that actually found in nature. The region of the
thickened accumulations is also necessarily, as I have said, one
of strengthened crust, under the petite ley poibeses and dis-

mung, making a dislocation of at least 16,000, and probably of

20,000, feet. And yet the Trenton limestone and Hudson River

shales are not metamorphic. Some local cases of alteration

occur there, including patches of roofing slate; but the greater
art of the shales are no harder than the ordinary shales of the
ennsylvania Coal formation.’

At a depth of 16,000 feet the temperature of the earth’s crust,
allowing an increase of 1° F. for 60 feet of descent, would be
about 330° F.; or with 1° F. for 50 feet, about 880° F.—either
of which temperatures is far above the boiling point of water;
and with the thinner crust of Paleozoic time the temperature at
this depth should have been still higher. But, notwithstanding
this heat, and also the compression from so great an overlying
mass, the limestones and shales are not crystalline. The change
of parts of the shale to roofing slate is no evidence in favor of
the efficiency of the alleged cause; for such a cause should act
uniformly over great areas.

In Southern Virginia, between Walker’s Mountain and the
Peak Hills, the Trenton rocks, as Lesley observes, are brought
mh by means of a fault, to a level with the Lower Carboniferous.
The amount of the fault by the lowest estimate is 15,000 feet.
Notwithstanding the depth at which the Trenton beds had been
ying previous to the faulting, the limestones are not granular
marbles, but ordinary stratified limestone.

Again, in the great Nova Scotia section, at the Joggins, 15,000
feet of rock are exposed to view out of the 16,000 feet or more
of the whole Carboniferous formation ; and the lower strata of
these 15,000 feet consist of shales and sandstones, and fossilif-
erous limestone, without metamorphism. .

at is the natural inference from these data? . Can we as-

* In a recent conversation with Mr. Lesley, he confirmed these statements, and
said that the upturned rocks are so situated that the srerelenate thickness of the
Series is easily ascertained. The facts are briefly alluded to in my Manual of Ge-
ology, on page 707.

at page 229, Prof. Ramsay gives the following statement respecting the
lowest of i Silurian beds.

we know, first appear in the Tremadoe slates in Britain. Of the Trilo-
bites, Agnostus princeps seems to be the fo species common to Lingula
flags and Tremadoc slate, and of a tolerably aig list of bivalve _
shells ET Davisii and L. lepis are re only forms that ascend from
the lower horizon. It was not till after the ea of Wales had been
mapped that the existence of the Tremadoc slate as a recognizable sub-
formation was suspected, for where almost all the rocks are slaty, an
where there is no visible break in aiipareis minor chological distine-
tions are eet of small value. AJ] known evidence e, however, tends
to prove that in Wales the Tremadoc slate is a ea rt formation, and
though searched for, none of its peculiar fossils have yet been found in
Wales, except in certain spots in Merionethshire and Caernarvonshire.

“Next come the Llandeilo and Bala beds, the prodigious development
of life in which had no Leg ag in the older ne formations; and it is
important to remember that the fossils of these strata are to a great ex-
tent different generically, an a7 entirely apoaitioall from those
known in the more ancient formation

“ With respect, then, to Lingula, Poetic ce, and Llandeilo and Bala
beds, taking into consideration the remarkable breaks in succession not
only of species but of genera, together with various physical points of
great significance, I have no doubt that actual unconformity exists in this
part of the series, and het there is a necessary connexion between these
facts. Indeed, this unconformity, if not seen, is, as already stated, nae
inferred, for while in Merionethshire the Lingula flags are from 5,000 to
6,000 feet thick, only 11 miles north, near Llanberris, their thickness is
only 2,000 feet, this reduction having been produced proba ably by wncon-
formable overlap. Close to —— Straits, if present at all, the Lingula
beds are still thinner, and in Anglesey they are absent altogether, so that
the Llandeilo and Bala beds lie. directly and, I believe, unconformably on
Cambrian strata. To show that this is not a mere local accident, let me
recall the circumstance that in Ireland and in Sutherlandshire the Lin-
gula flags are also absent, and Llandeilo beds lie unconformably on Cam-
brian grits and conglomera

exhibited to the Academy of Sciences at Paris a yellowish diamond, of
the size and quality that otdieiarily sells for 12,000 dollars, which on
being heated changes its color to rose-red; this color it retains for two
or three days and then wredlially resumes the original yellow. On account
of this peculiarity the actual value of the diamond was stated to be three
times the amount above mentioned.—Les Mondes, p. 85, May 10, 1866.

side of this, there are red spots where alteration has com menced ; an
beyond, the mineral is changed to a brick-red uniform material, mostly
opaque, with some translucent spots of unaltered elzolite. This red ma-
terial afforded 5:90 p. c. of water, and dissolved only partially in dilute
nitric acid, it yielding an abundant red precipitate. On separating the

5. Origin of the Diamon . B. pe Cuancourrors has presented
‘ie view that the diamond has hace formed from hydrocarburetted ema-
nations, as sulphur is formed from hydrosulphuretted emanations, and
that its origin is thus connected with the previous existence of petroleum-
bearing or bituminous schists. In the oxydation of sulphuretted hydro-
gen in solfataras, all the hydrogen is oxydized, but only part of the sul-
phur passes to the state of sulphurous acid in this humid process of com-
bustion. So, in an analogous manner, the diamond was probably formed ;

a
in which all the e hydrogen was oxydized, but only a part of the carbon
was transformed into carbonic acid. This view accords with the occur-
rence of the diamond in arenaceous rocks or itacolumites, which are
mostly metamorphic rocks of paleozoic age, and which may have once
been bituminous either by original formation or by emanations from

that of the metamorphism to which the ae Oi rocks have
SENET ti been subjected, and which may have been essential to the

. Wittram Henry Harvey, whose lamented death was announced

in the last number of this Journal (p. 129), was born at Summerville,
near Limerick, Ireland, on the 5th of February, 181 1. His father, Joseph
M. Harvey, was a highly res merchant in that city, and a member

of the Society of Friends. William Henry was, we believe, the young-
est of several children. He received a good education at Ballitore School,
~—an institution of the Friends, and on leaving it was engaged for a time
in his father’s counting-room, devoting, however, all his spare time to
Natural History, his favorite pursuit even from boyhood. He made con-
siderable attainments in Entomology and Conchology, and in Botany he
early turned his attention to Mosses and oe To the study of the

Dr. Harvey was one of the few botanists of our aye who excelled both
in phenogamie and cryptogamic botany. In Algology, his favorite
branch, probably he has wie? no superior ; in systematic botany generally
he had now an —— position. He was a keen observer and a capital
describer. He in cosa accurately, worked readily and easily with
microscope, pencil aa pen, wrote perspicuously, and where the subject
permitted, with captivat inet grace ; affording, in his lighter productions
mere glimpses of the w and poetical imagination, delicate humor,
refined feeling, and sincere hacia which were charmingly revealed ie
intimate intercourse and correspondence, and which won the admiration
and the love of all who knew him well. Handsome in person, gentle
and fascinating in manners, genial and warm-hearted but of very retiring
ma a simple in his tastes and unaffectedly devout, it is not surpris-
ing that he attracted friends wherever he went, so ie his death will be
sensibly felt on every continent and in the islands of the sea. A. G.

spect, that at the age of seven he was examined in Hebrew by @
Fellow of Trinity College, Dublin, and that “the child passed
a better examination in that language than many candidates for
the fellowship.” For obvious reasons we hope there is some par-
donable though very natural exaggeration in the statement. It
is certain however that the attention of the Persian Ambassador,

n on a visit to Dublin, was attracted by a letter of greeting
written in Persian by young Hamilton at the age of fourteen.
Whether or not any allowance is to be made for the shadow of
the future overlapping the memory of the past, it is quite certain
that the vast intellectual capacities of the boy were evinced and
cultivated at a very early age, and what is of far greater conse-
quence, this early mental activity did not prostrate or forestal
the successful exertions of maturer life. It is quite possible that
the literary turn thus given to his earlier pursuits may have hap-
pily laid the foundation of that peculiar combination of meta-
myer and poetry, which distinguished some of his mathemat-
ical performances from those of most other men. For his early

‘processes in the Mécanique Céleste. Meanwhile, and notwith-

standing this very unusual advancement in mathematical knowl-
edge, the main culture of his mind had been classical ; and that,
not alone from natural predilection, but on account of the re-
quirements of the collegiate course on which it was his intention
to embark and to compete.

It is almost needless to say that young Hamilton, with a mind
thus disciplined and furnished, entered upon his course at Trin-
ity College, Dublin, if not without able competitors, at all events
without an equal, whether in literature or mathematics. As
might be expected, he carried before him; and when we
speak of success in his literary efforts, it must be understood

this encouragement to the young philosopher was the speedy :

certainly more expressive, amenable to the principle of no waste

In 1828 Hamilton became a Fellow of the Royal Astronom-
“ical Society, and thus at the time of his decease was among the
oldest, as his name was certainly among the most honored, of
our members. In 1833 he made known, in one of several sup-
plements to the “Theory of Systems of Rays,” his great discov-
ery of Conical Refraction. In this memoir, starting again from
the principle of least action, and, as before, conducting the inves-
tigation by means of a single Principal Function, he establishes

the entire theory of double refraction; and, applying it to the

case of biaxial crystals, by a new and simpler method’ than that
originally pursued by Fresnel, he obtains the equation to the
form of the wave assumed by the vibrating ether within the
erystal. On examining the form of the wave surface, Hamilton,
with remarkable sagacity, observed that if the theory and the
results were true, a single ray of light incident at a certain angle
on a biaxial crystal, must of necessity pass into it, not as one ray,
nor even as two rays, but as a conical sheet of light, and then
finally emerge as a luminous cylindrical surface. And, again,
his profound and complicated analysis indicated that there was
also a direction within the crystal, such, that if an internal ray
of light passed along it, it would emerge from the crystal, not as
one ray, but as a luminous conical shell. Such results as these
were not only apparently contrary to all analogy one expecta-

experiment was at length successfully performed by Dr. Hum-
phrey Lloyd, of Dublin, whose patient ingenuity, and faith in

i e Professorship of Astronomy. He retained this distin-
guished office for eight years, and on his resignation he received
the thanks of that eminent-Academy “for his high and impar-
tial bearing in the chair.”

In 1834 and 1885 he communicated to the Royal Society two
papers on “ A General Method in Dynamics.” Here, again, he

and on the poetic power which almost invariably is, at the least,
latent within them, we cannot refrain from quoting the following
sonnet, written by a great Astronomer, on the occasion of a visit

S. Porter on the Vowel Elements in Speech. 303

Arr. XLU.—The Vowel Elements in Speech ; by SAMUEL Porter,
of Hartford, Conn.

[Concluded from page 189.]

THERE are certain modes of action of the organs in vowel utter-
ance, which are to be noticed as the ground of some important
properties and relations. It is observable that the open vowels

fectly natural on mechanical and physiological principles. ‘The
vowel in téte, &c., is unquestionably such as to be accounted fo

ble of the same abrupt, explosive quality ; and, when prolonged,
usually tend to become more close, or, when at the closest, to
move forward into a contiguous or otherwise related vowel of
another group. These effects, again, we ascribe to the peculiar
ode of action of the tongue, as, after coming into line for the
group, it has to be raised to the proper degree of closeness: it
is like raising the arm a little way after extending it. This mo-
tion cannot well be suddenly and firmly arrested so as to pro-
duce an abrupt or explosive utterance. It is also more natural .
to continue this motion than to hold it arrested so as to prolong
the vowel unchanged. Obviously, also, the effect of continuing

the impulse, after reaching the closest degree, would be to raise,
or bend up, the tongue at a point further forward, and so to carry
the vowel into another group. The middle may, however,
sometimes take the course of the open degree, and move a step
backward in becoming more close when prolonged.

The tendency of the open-depressed vowels, when prolonged,
is, for like reasons, in the opposite direction: they incline to
greater openness, so far as possible, or else to a backward move-
ment. Thus, self, ten, &c. drawled into the open-depressed de-
gree, incline to the @ if still further prolonged.

t is to be remarked, that the turn taken by vowels under
change of quantity will be much influenced by the character of
consonants succeeding.

their bearing upon vowel change in etymology, and as explain-

or derivation; as Wort-Worter, Hand- kurtz—kiirtzen ;
and as Bett, Ende, from old badi, andi; ina of it in Tingiah
are bed, end, men, sell (Goth. salyan), and other cases not a few ;
—and in the Old N orse, for instance, a takes umlaut from u in
the néxt syllable. The umlaut is believed to have come up
through an intervening stage of diphthongation,—badi, for ex-
ample, becoming first bazdi and then bedi or bed: but whether
so or not, reference to it here is pertinen nt.

I maintain that such change is to be explained almost wholly
by palato-lingual action. Of course it is so in the case of e or @
from az. As for au, labial position would not determine its re-
duction to o or d rather than toa labial d. In the # from wi or wu,
there is seenly an admixture of a consonantal y, such as fae

from the rapid utterance of the extremes in close succession
than from an attempt to effect their simultaneous utterance.
The developed product does not necessarily take the quality of
either of the two extremes.

Change from a diphthong to one of its components, by dropping
the other, is also not uncommon. Thus from A.-S. ea, we have
shall, sharp, hard, calf, &c., as well as deaf, head, red, ee ; from

a eo, seven, heaven, devil, &e.; and we have benefit, parish,
venison, comparison, &e., from the old or the later French bien-

, Veneison, comparaison.

ian, the 7 prefixed to e and wu to o, form a marked feature: as
fiero, sieda, buono, &e. Examples of the new element suffixe

digraphs having been once actual diphthongs. All such changes
must accord with the laws of diphthongal combination, as before
stated; to which may be added, that it is in converting a short
vowel into a long one, and in giving greater quantity or weight
to one already long, that the tendency to diphthongation is usu-
ally manifested.

The changes of this sort in the Italian as evolved from the

the scheme here set forth. The Italian exhibits a remarkable
regularity in its development, having been little disturbed by
outside influences,—and is thus, so far as it goes, peculiarly

for the establishment of principles of phonetic change. There
are recognized in Italian an 7 vowel, and a “close” and an “open”

or nearer to the é, and the open (aperto) either precisely or nearly
like the d So there is a wu, and a “close” and an “open” 0,—
the close nearer to the u, and the open probably nearer the 4,

except the condensation of the diphthong,—just as ought to be
expected in connection with the actual changes as above stated.
Similar laws and tendencies have had partial sway in the other
branches of the Latinic family.

Every language under the sun will show examples, in abund-
ance, of changes, more or less regular, by direct transition from

The point we have in hand,—that of direct transition from
one vowel-group to another,—will be best illustrated by taking
into view, etymologically, the ancestral and allied tongues along with
the English, and adverting also to existing dialectic variations,—
with this proviso, however, that the precise process of change
cannot always be determined as direct rather than indirect and
circuitous.

transition is easy to Fr. 7, or z in azure, to sh, or Fr. ch, and to s,

presented a partial obstruction, of a yielding nature, over which
the vocal current breaks, or by which it rubs, producing a murs
mur, burr, or trill, only, instead of a reverberation and ringing
out of the sound.

Turning again now to the w, we find here a contrast of ten-
sion and non-tension of the lips as a further distinction between
this consonant and the vowel u!/, is may be made visible
and palpable in the word woo, which presents the two elements
quite open as labials to external observation.

In explaining the theory of the diphthong, there was occasion
to notice the development of w between two vowels whose suc-
cession involves transition from a close to an open position of the
lips,—as in the Fr. out and the Eng. ae f ' y in hke
manner in the transition from a forward to a backward (or what
some would call a close and an open) palato-lingual articulation,
—as in million, billzard. Now, such transition requires a relax-
ation of the tension which characterizes vowel-articulation ; and
either a hiatus or a consonant must intervene. The simple re-
laxation of the articulating organs, with continuance of the tone,
gives us win one case and y in the other. From this we may
conclude, first, negatively, that these consonants are not more
close than the vowels from which they are developed by transi-
tion to a more open position; second, positively, that this relax-
ation, or non-tension, is what essentially distinguishes these con-
sonants from the vowel

most remarkable forms. I regret that words alone cannot, at

this time, render their peculiarities as evident as I hope the illus-

trations will, in my forthcoming paper, in the Memoirs of the
oston Society of Natural History.

I must ask the reader in the first place to go back with me
almost to the Ultima Thule of animal simplicity, and revise the
organization of the hitherto too lowly estimated Monas, in order
to lay the foundation for the group which embraces in its limits
80 gigantic a family as the Spongie Ciliate. o not think any
one will be prepared to fully appreciate such a remarkable defi-
niteness and system in the arrangement of the organization of

onas as I have discovered among the various forms which con-
stitute that genus. ;

itherto a Jfonas has been looked upon as a mere shapeless
molecule, with a vibrating cilium of some sort or other, attached
to its surface at an indefinite point. As I understand the rela-
tion of parts, now, the motory cilium or flagellum is perhaps the
most remarkable feature of the whole animal, not only in a
physiological aspect, but also in its topographical relationship.

t me illustrate this by a description of the body and append-
ages of Monas termo Ehr. :

The body of that species has the form of a wide, compressed
heart, with two distinct summits. The broad flattened sides lie
Opposite to each other, and parallel with the plane which passes
through the two summits, and which forms the prolongation of
the greater transverse diameter of the body. Between these sum-
mits is. an aperture which constitutes the mouth. One of the

the body. This remarkable feature is scarcely to be recognized
during the free state of the animal; but when the latter is moored

transverse diameter coincident with the line of vision. The
then seems, at first sight, to have a symmetrical aspect, such as
is not observable from any other point of view; and such it
might be made to appear if I should belittle the importance of
one single organ, by simply mentioning its existence, and omit-
ting to lay down its exact topographical relationship. I refer to
the contractile vesicle. During the systole of this organ it is so
inconspicuous that it would easily escape even the most careful
observation; but during the transition to the expanded state,
and at the full diastole, its prominence, from the point of view
just mentioned, is so great as to rival the flagelium in attraction.
It may then be seen as a comparatively large, rounded, trans-
parent, vesicular body, which stands out in strong profile, just
in front of the middle, and close to the-surface of the left side of

e body. At full diastole it even forces the overlying region

fo
side, viz: to show that they are not adult. I think moreover
that I am fully warranted in assuming that a Monas which
sesses such an organization as I have described, and is attac

to a stem, is an adult; and more especially so since, among many
hundreds which I have observed from time to time, I have never
seen any trace of a transition to a higher form. That such
simple organizations can exist without rising toa more compli-
cated state, during a whole lifetime, I am furthermore sustained
in believing by the discovery of some new generic forms, which,
although scarcely, if at all, more highly organized than Monas,
have in addition such characters as would seem to stand in the
way of a transition to a more elevated grade of existence. For
instance, the presence of a calyx about the body of an infusorian,
into which it can retreat, is an indication of a fixity of condi-
tion which corresponds to the adult state. Thus I found one of
the new genera which I just alluded to. :
Bicoseeca, as it is called, may be described in general terms as
a stemless Monas which is attached to the bottom of a calyx, by
a highly muscular, retractile cord. All the organs have the same
remarkable definiteness of relationship and peculiarity of form
that Monas possesses; and in addition there is the muscular cord
which, with oft-repeated jerks retracts the body to the very bot-
tom of the calycine envelope. ere are two singularly diverse
species of this genus; one marine and the other lacustrine. -
The most interesting infusorian of this group of new forms is
the one which I have called Codosiga. This links the Sponges to
the flagellate Infusoria. Its greatest peculiarity consists in the
Sapien of a highly flexible, extensible and retractile, nem-
ranous collar, or hollow cylinder, which projects from the an-
terior end of the body. The cylinder is slightly flaring, and, if
we include the asymmetrical body, the whole might be compared
toa very deep, one-sided bell, with its narrower end half filled
up. The single, sigmoid-arcuate, rigid flugellum arises from the
depths of the bell, exactly at the middle of the truncate front,
as it were forming a prolongation of the longitudinal axis of the
y- There is no lip, and the flagellum, which rises close to
the mouth, has a strong resemblance to that of Monas, both in
proportion, form, and habits; and performs the office of a pre-
hensile organ when the body is fixed, or acts as a propeller dur-
ing natation. ‘The contractile vesicles are two, or even three, in
number, and lie in the posterior third of the body. The only
Species of this genus which I know of is gregarious in habit,
but usually not more than four or five bodies are to be found at-
tached, like Anthophysa, by their narrower, posterior ends, to
the branchlets of a single forking stem. The peculiarity in re-
gard to the direction of the curvature of the flagella in a back-
ward direction, toward the stem, is as highly marked in Codosiga
as in Anthophysa (described by me in the September number
of this Journal) and there is also the same fixed relationship of
the longitudinal and the’ greater and less transverse d
of the several individuals of the colony.

324 H. J, Clark on the animality of Sponges.

There is still another new genus which I would like to men-
tion here because it forms a collateral link with Codosiga in the
affiliation of the Sponges with the Monadina. This genus I
have called Salpingeca. It is, as it were, a single individual of
Codosiga which does not possess a stem, but is seated in a calyx,
from which it protrudes, or into which it retracts, at will. There
are three well marked species, of which one is marine.

I come now to the principal object of this communication.
The sponge which formed the main basis of these investigations
is the well known marine species Leucosolenia (Grantia) botry-
oides Bowerbank. It is preéminently a branching form, and, on
account of the slenderness and transparency of its tapering,
hollow ramules, is‘a most desirable object for study. A branch-
let—and in fact the whole colony—may be stated to be essen-
tially a double tube. The outer tube consists of a glairy, gelat-
inifurm stratum in which the spicules are im in a certain
order, and is pierced by numerous ostioles, which are continued
through the interior tube to its hollow center. The inner layer,
or tube, is entirely made up of the individual members of the
colony, the bodies of which are packed together closely, side by
side like pavement stones, with their posterior ends slightly im-
bedded in the glairy substance of the outer tube, and their an-
terior ends projecting freely into the general cavity. To de-
scribe the shape and organization of one of these individuals
would be to repeat, almost word for word, what I have already
said of the monad of Codosiga ; in short Leucosolenia bears some
such sort of relationship to Codosiga that Salpingeca does; the
latter being as it were a stemless Codosiga seated in a calyx,
whilst Leucosolenia is comparable to a stratum of the monads
of Codosiga imbe in a spiculiferous envelope. It is clear
therefore that the organic difference between Leucosolenia and
Jodosiga is scarcely enough to locate them in two different faml-
lies; in fact I am inclined to consider them only as generically
distinct, and hardly, if at all, more widely separated in this re-
spect than are Salpingaca and Codosiga. :

Index to the Species.

Tue description of the species of Carex of our country in
this Journal was especially designed to aid those who had just
entered upon the study of our plants. It was begun in 1824,
only seven years after the great impulse, produced by the lec-
tures of Professor Amos Eaton, to the study of botany and some
other branches of natural history. There were few works on
botany accessible to students; and, even when I had in 1815
ascertained the principles of the Artificial System of Linneus
and studied the genera in a general botany, no work describing
the species was accessible. ‘Che Gramina of Dr. Muhlenberg
was published in 1817, and his Catalogue of our plants a little
earlier, These, with Persoon’s Synopsis, the Reedgrass of Chris-
tian Schkuhr, and a Botanical Dictionary, were the works of
which Eaton made such valuable and extensive application. The
standard authors on Carices then were Schkuhr and Muhlenberg;
and they were implicitly followed, even in the few mistakes they
made, and for the correction of which no method occurred for
many years. As knowledge of the species increased, the diffi-
culties became perplexing, especially in relation to Carex erinita
and C. paleacea, C. oligocarpa and C. digitalis, C. folliculata and
var. xanthophysa, C. plantaginea and C. anceps. W hile American

otanists have solved many of the difficulties, far more has been
effected in the study of our North American Carices by Francis
Boott, M.D., of the Linnzan Society, England, who enjoyed the
greatest facilities and showed the most persevering activity.

n the Index, the quoted authorities are necessarily few. The
name of the species, or the jirst name (when more are given), is
considered the designation due to the species; the synonyms are
in talics, The references, besides Schkuhr and Muhlenberg
already mentioned, are chiefly the following:

Monograph of N. Am. Cyperacea, by John Torrey, M.D., pub-
lished in 1838, and his Botany of the State of New York, 1843.
The reference is Mon. 1836, or Tor. 1836 or 1843, or both. _

Flora Boreali-Americana, Michaux, 1803. Though earlier
deem. it was of little use to us, till the result of Dr. Torrey’s
‘xamination of the Herbarium of Michaux in Paris, was pu
lished in vol. xxvii, 1835. ge :

arices Am. Septen. Exsiccate; edidit H. P. Sartwell, M.D.,
1848. ParsIet II. This collection of Carices, not figures, 158
in number, nearly all correct, and fine specimens, is very inter-
esting. The reference is Sart. or Exsic. 1848. ey

Prof. Tuckerman’s Enumeratio Methodica, 1843, scientific, dis-
criminating and curious, has some important references. :

Trans. Lin. Soc., 1843; 3. Six new N. Am. species of

Carex, in Boston Journal of Nat. Hist., 1845; 4. De Carietbus,
in Hooker’s Journal of Botany, 1846; 5. Caricis species Nove
vel minus Cognitae, Lin. Soc., 1851; 6. Illustrations of the
Genus Carex, Part I. 1858; Part II, 1860; and Part-II], 1862.
These are severally quoted as Boott 1840, Boott 1851, &c. Boott’s
Illustrations of Carex is a magnificent work containing fall de-
scriptions and splendid figures of 291 species on 126 pages and
411 plates, forming three large folio volumes. It is proper to
add that Part IV was nearly complete for the press, when this
admirable man and botanist was removed by death, on Christ-
mas morning, 1864: born in Boston, 1792, and died in London.
With noble generosity too he distributed the “Illustrations”
among his numerous botanical friends.
_ Figures of 119 species (numbered 117) are given in several
volumes, ending vol. xlix, 1845. There are in vol. ix, 12 fig-
ures; vol. x, 11 figures; xi, 26 figs.; xii, 2; xiv, 5; xxv, 3;
xxvi, 2; xxviii, 6; xxix, 18; xxx, 9; xliii, 4; xlviii, 8; and
xlix, 12 figures. Many of these are finely characteristic; but
want of space prevents more particular reference.

The following notices are important: :

1, A Catalogue of one hundred and twenty-eight species 12
vol. xi, pp. 819-825, 1826, as then understood. Due attention
was not paid to priority of names.

2. Species of Carex in the Herbarium of Dr. Muhlenberg, as
named by him, in possession of the Am. Phil. Soc., Philadel-
phia, compared with the species then current, vol. xxv, PPp-
142-6, 1834.

8. Carices collected in’ Arctic America by the English Explor-

5 m

(or more) of Carex, many more will probably be added in the
coming twenty years.

Art. XLV.—On the Oil-producing Uplift of West Virginia; by
Prof. KE. W. Evans,

THE most productive oil region of West Virginia, so far as
developments have yet gone, is ; confined to a line of uplift, ex-
tending from Burning Springs on the Little rye: in a di-
pele from twelve to fourteen degrees east of n rth, to the
Ohio river,—a distance of 35 miles. Thus iinited. the line is

pn soe which will therefore serve as a convenient point

In its central portion, which for convenience I shall wei sts
as the middle segment, the upheaval is most marked, an
hibits some pipes features. This part is about ten mails in
length, arid is also nearly bisected by the railroad. A cross-
section of it, as ands out from the railroad cuttings, the records
of borings, and the frequent exposures of rock along the streams
of the neighborhood, is shown in fig. 1, It is a decapitated

ope.

To the westward from A, and to the eastward from B, there
is a somewhat sudden transition from the steep slopes to a com-
paratively slight inclination of the strata, which continues far
enough to either side to give an additional outcropping of about
200 feet, estimated perpendicularly to the strata.

It is not claimed that these figures are accurate; but if they
are approximately correct, the rocks on the summit of the anti-
elinal have been brought up out of place not less than 1100 feet,
probably as much as 1200 at the highest axial point. This es-
timate has reference to the place of maximum upheaval, a little
north of the railroad.

main uplift. One of these, represented at E, is quite prominent
and persistent, and in fact constitutes the crown or proper axial

The most distinctive features of this segment of-the uplift are
seen in the abrupt change of direction at Band F. The Appa-
lachian folds farther east, where there was more heating and
crystallization, exhibit curves rather than angles, even when
most prominent. But here we find sharp angular points, with
some arching to either side, but upon the whole partaking rather
of the character of fractures, and affording numerous crevices
in the soft and brittle rock. Hence the popular name of “the
break,” by which this uplift is known, is not altogether inappli-
eable. There is, however, no actual disruption of the strata,
and no fault, either at the western angle B, or at the easte:
angle F. The abruptness of these angles has led some into the

supposition that the nearly horizontal strata of the inner belt
are not continuous and identical with the inclined strata to

either side, but abut against their sides or faces, in the manner
exhibited in fig. 2. That such is not the case is conclusively
shown by the following facts.

First, a comparison of the rocks in the western slope, from B
to A, fig. 1, by their lithological characters, with the rocks in
the eastern slope, from F to G, shows that they are identical one
by one in their order;-they are also found identical with the
rocks in the intermediate hills, as at D, so far as these extend
upward, say a maximum height of about 300 feet. The strata
thus traced over include sandstones, shales and veins of coal;
also a layer of flinty limestone, which may be mentioned as one
of the best guides. At the railroad this appears on the west
side projecting upward through the bed of Laurel Fork, and on
the east side in an exposure of sloping rocks in the hill a little
south of Petroleum station. At various places it not only ap-
pears in the opposite slopes, but has also been traced through
the hills between, as on Comb run, about two miles south of the
railroad. Indeed there are numerous exposures in situations
corresponding to B and F, fig. 1, where the continuous connec-
tion of the same strata, as they change from an approximately
horizontal position to a steep pitch, is plainly traced by the eye.

Again, it is a fact that the rocks bored through in positions a
little to the left of B, fig. 1, correspond, in lithological charac-
ters, with those found to the right of it, but differ from the latter
in being struck further down, and in continuing longer in pro- :
portion to a greatly increased inclination. Borings made at

descend into rocks of steep pitch. All this is in direct con-
tradiction to the hypothesis presented in fig. 2, where the slop-
ing rocks are.represented as not only distinct from, but also as
projecting over the horizontal ones.

The inner belt between the slopes, from B to F, is not inap-
propriately called the “oil belt,” as it is only in the horizontal
or slightly inclined rocks between these limits that oil has been

und in paying quantities. In the upturned edges of the east
and west slopes, as well as over a considerable extent of terri-
tory outside, a large number of wells have been bored for oil,
but with little or no success.

Even within the inner belt, the producing wells are thus far
nearly all confined to three narrow strips. It will be seen that
the cross section, fig. 1, exhibits three principal angles, marking
three distinct axial lines; the western angle at B, w i

axis plane, approximately bisecting the angle at B, it would of
course incline to the eastward from B in its descent, as repre-
sented in fig. 1. Accordingly the most frequent strikes, and
generally the best wells, are not on the side next to the slope,
ut on the eastern half of the strip, toward C, where this main
line of crevices, in its eastern ramifications, would cross the above-
mentioned sandstone, after it has become horizontal.

On the eastern margin of the inner belt, the main if not the
only developments are on Gales’ fork of Myers’ creek, about
three and a half miles north of the railroad, where there are
some good wells, confined to a similar narrow strip, just west of
F; but the production is not so large, in proportion to the num-
ber of wells sunk, as on the western margin.

_ On the inner axis, at E, and a short distance to either side of
it, there have been numerous strikes on Oil Spring run, from

erevices still covered by a mass of horizontal rock, where oil is
now found.

The surface rocks of the country adjacent to this uplift, on
either side, are well known to be those of the Upper Coal-meas-
ures. The lowest rocks brought to the surface by the upheaval
are undoubtedly those of the Lower Coal-measures. ‘This is in-
dicated by the occasional appearance of Lepidodendra. In the
hills between the slopes there are three or four veins of coal,
and their equivalents are found in the inner strata of the slopes;
but where the upheaval has been greatest, I think only two
seams have been detected in wells sunk in the valleys ;—those

carboniferous (or Vespertine); or, as from data furnished by
Rogers we may infer that the latter is but slightly developed
in this region, and may be represented by the thin conglome-
rates just mentioned, it is probable that the sandstone belongs
to the Chemung group, overlying the black shales, and consti-
tuting the geological horizon of most of the oil obtained in
Pennsylvania.

Art. XLVI.—Remarks on the Drift of the Western and Southern
Sales, and its relation to the Glacier and Iceberg Theories ; by
Eve. W. Hitcarp, Pb.D., State Geologist of Mississippi.

IN a recent paper on the Quaternary formations of Mississippi
(this Journal, May, 1866), I have expressed my views concerning
the remarkable formation designated as the “Orange Sand,” in
my Report on the Geology of Mississippi.

The admirable exposition of the whole subject of the Post- ’
tertiary formations in Dana's Manual of Geology, to which I have
since been enabled to refer, as well as the portion of Dana’s Ad-
dress before the American Association in 1855, relating to that
period, Suggest to me with greater clearness the points to be set-
tled in establishing the presumed correspondence of the Orange
Sand of the Southwest to the recognized drift of the Northwest.
On this subject I now propose to offer a few additional remarks,

T have not perhaps, in the paper referred to, been sufficiently
explicit, in comparing the Orange Sand to the northern drift in
general, without specially mentioning as its supposed congener,
the drift of the Northwest, particularly that of Illinois, Wiscon-
sin, Iowa and Missouri. That the drift of New England, as de-
scribed by Hitchcock and Dana, can be satisfactorily accounted
for on the glacier theory alone, few who have delved among the
ancient and modern moraines of Switzerland will question,

ut the Western drift deposits, even so far north as Towa, as

Hall's observations show, and still more in Iilinois and Missouri,

differ seriously in their structure both from the New England

moraines, and from the lines of blocks apparently left by the
glacier melted zz situ. In the West the “erratic” blocks, both

an appearance rarely extends connectedly beyond a few yards,
nor is it likely it ever should, however stupendous the scale o
the glacier. Nor will any one, acquainted with moraines and
their material, be likely to mistake an aqueous deposit for a
moraine, or vice versd.

In Desmoines county, Iowa, according to Hall, the drift con-
sists of “partially stratified deposits of clay, sand and gravel,
with boulders of primary and secondary rocks irregularly dis-
tributed through the mass, though usually most abundant in the
lower portion.” These boulders in the description of Lee county
are spoken of as “worn and rounded masses” of various rocks,
occurring in distant localities. We have the same in Henry
county; in Van Buren, this deposit furnished ‘a mass of sill-
ceous wood,” which ‘presented none of the water-worn charac-
ters of a boulder; but the angles were as sharp and well defined
as if it had never been removed from the spot where it was at
. first buried.” In Washington county, again, we find mentioned
“a heavy deposit of drift material presenting the usual charac-
teristics of this formation, and consisting of irregularly stratified
beds of sand, gravel and clay, with an average thickness of from
forty to sixty feet.” : i

The above, taken verbatim from Hall’s Towa Report, might
serve as a very fair description of a good portion of the Or-
ange Sand of Mississippi, the only difference being the greater
size of the boulders in the more northern locality; a merely
quantitative variation.

In Missouri the phenomena are the same. The drift there,

The latter remark is interesting, as it shows precisely what I
found to be the case in the eastern: pebble belt of Mississippl.
The pebbles there are almost exclusively derived from the sili-
ceous group of the Carboniferous, which occurs only in patches
farther northward, but underlies the pebble strata themselves

stratigraphical position.
This, also, is precisely the predicament of the Orange Sand
deposits, :

Hilgard on Drift in the Western and Southern States. $45

As for the drift of Illinois, I am unable to refer to the Reports
of that State; but my own early recollections of it such as it
exists in St. Clair county, place it in precisely the same category
with the drift of lowaand Missouri. Only I remember distinetly
the occurrence in it, of angular boulders of syenite, greenstone
and quartzite.

delta south of it. And even as far south as Vicksburg, the ac-
tion of waier alone is inadequate to account for the transportation
of the boulders found in these beds.

Dana's remark (Manual, p. 554) that “ while the glaciers were
disappearing, many a stream or lake would have existed to strat-
ify the drift, and cause denudation in elevated places,” points no
doubt to the true explanation of these phenomena: but it does
not go far enough to satisfy existing facts. Agassiz has obser-
ved that “the melting snows of the declining glacier epoch” may
have been instrumental in the formation of the river terraces ;
but Tuomey was, I believe, the first to point out, that the South. .
‘ern drift may have been formed in consequence of the sudden
melting of the northern glaciers (Second Report on the Geology
of Alabama, ed. Mallet, p. 146); such as would have resulted
from a first, rapid depression of so huge a mass of ice below the
snow line.

The assumption of a pretty rapid depression seems necessary
to account for the immense volumes of water required to produce

with ice-cold water by the enormous influx rom the glacier re-

a state of violent flow. ;
That the action must at first have been extremely violent, is
Proved by the deep erosion of the un:erlying formations, ant
the transportation and subsequent redeposition in mass, of their
Materials, more or less altered; which 1s exhibited on so exten-

Sive a scale in Mississippi. But for the fact that wherever the

316 Hilgard on Drift in the Western and Southern States,

more ancient strata were readily susceptible of denudation,
they have entered largely, at times almost exclusively, into the
composition of the Orange Sand strata, we might suppose that
the surface of the former (which appears to be at least equally
as hilly as the present one) had been denuded by atmospheric
agencies during the glacial period of elevation.

When, after the subsidence of the first rush, the velocity of
the water had so far diminished as to render it capable of form-
"ing stratified deposits, these would naturally possess the mixed
character resulting from a twofold mode of transportation—by
water, and by floating ice—the former, no doubt, in many cases,
succeeding the latter, and, by the grinding action of the smaller
gravel and sand, transforming the angular blocks first dropped
into the rounded boulders characterizing the drift of Iowa and
Missouri, and faintly represented by their scattered congeners
in the Orange Sand delta.

t would thus seem that the grandly simple means of a single
elevation and re-depression in the northern latitudes, to which
; enomena of the ancient glaciers and sea-beaches point us,
will equally satisfy the conditions required for the formation of
the Western and Southern Drift. Down to the. later stages of
the northern re-depression, the predominant slope would every-
where be southward, so as to collect in the Mississippi valley the
glacier waters, not only of the whole extent of northern terri-
tory now tributary to it, but probably also those of the present
arctic slope of British America, and a portion of that now trib-
utary to the St. Lawrence. Hence the comparative absence of
stratified drift from the Northern Atlantic slope of the United
States; and its presence, on the contrary, on the sea border of
the Southern States, as stated by Tuomey, 7. c.
_ As to the Champlain epoch, it would seem to be represented
in its later part only, by that which in the Western and Gulf
States has formed the “second bottoms.” In the Mississippi Val-

nels greatly exceeded that which corresponds to the era of the
second bottoms, south, or to the bottom prairie of Missouri.

he only sea-beach terrace now existing on the Gulf coast, and
with which the second bottoms show a manifest confluence of
level and material, is from 18 to 24 feet above tide-water. But
the evidences of sea-beach or tidal action extend far back into
the interior (Miss. Rept. p. 29), so that in fact, the second bottom
of the Pascagoula exhibits that structure, and not the usual one
resulting from flowing water, throughout its course. The same
structure, moreover, extends to some elevation into the border-
ing uplands, where these sands overlie the Post-pliocene beds an
Orange Sand.

The present beach terrace of the gulf coast cannot, therefore,
be considered as the true measure of the amount either of de-
pression during, or re-elevation subsequent to, the Champlain
epoch. Whether the great absolute elevation of some of the
Orange Sand ridges of Mississippi and Alabama (probably ex-
ceeding in some cases, 700 feet) necessitates the assumption of
even a greater depression than the present beach-marks would
indicate, the known facts are hardly adequate to determine.

those mentioned by Assistant A. Schott on page 84, part ii, of
Major Emory’s Report on the Mexican Boundary Survey, and
which are laid down as occurring 90 miles northwest from Santa
Rosa; but whether he refers to the Santa Rosa of Cohahuila,
lat. 28°, long. 101° 30’, is not certain. They certainly do not
seem to belong to the locality on the Sancha estate, from whence

from Santa Rosa, Cohahuila.
Description of the specimen.

It is a flattened cleavage mass rather above a quarter of am
inch in thickness, by two inches in length and one and a half
broad. It weighs 120 grams, or rather more than a quarter
of a pound. Its color is dark iron-black without any appear-
ance of iron-rust. About three-fourths inch square of one of its
sides exhibits the original surface of the mass, showing three
well marked though shallow polyhedral depressions, but, like
the Madoc, the Texas, and many other irons, without any well
defined crust. For the rest, the two broad surfaces are nearly

cleavage in the mass. e
are also plane, and have resulted from octahedral cleavages.

eighth of an inch in thickness, a fragment weighing six grams

of the mass. The brilliant capillary points, when more nearly
examined, seemed identical in size and character with the rhab-
dite crystals of Reichenbach, so beautifully figured in Prof.
Rose’s admirable memoir on meteorites,’ as occurring in the
Braunau meteoric iron. The lens also shows upon the cleavage
planes of the iron, those peculiar striae which Prof. Rese has
pointed out as occurring in the Braunau iron; in particalar,
such as are parallel to the edges and certain diagonals of the
cube, and which Prestel has shown to be present also in cleavage
crystals of artificial iron. So far therefore as one sample can
show, the structural identity of this iron with the interesting
Braunau mass is very clear.

which they have fallen?

$1. Two years ago I communicated to this Journal the re-
sults of a preliminary investigation of the distribution of the
dark lines in the spectra of some of the elements, especially the
spectra of the alkaline earths and iron.’ At that time no exact
and comprehensive determinations of the wave-lengths corres-
ponding to these lines had been made; our investigation was
therefore necessarily based upon Kirchhoff’s arbitrary millime-

Having now some direct determinations of wave-lengths, we
resume our investigation. It will be seen that the results of our
preliminary investigation are fully confirmed in their essential
features, and that the number of elements to which they apply
is greatly enlarged.

number of the lines laid down in Kirchhoff’s map of the spec-
trum, thereby enabling us by a simple geometrical interpolation
to find the wave-length of any of Kirchhoff’s lines with great
accuracy, the number of lines determined by Ditscheiner being
sufficiently extensive to warrant the use of a large scale in this
interpolation. The scale we used was 1 mm. of Kirchhoff’s scale
and one ten-millionth millimeter wave-length, severally equal to
two millimeters. On this scale the length of the spectrum from

to G, or from 600 mm. to 2800 mm. Kirchhoff, taken as ab-
Scissx, becomes 4400 mm., or nearly 15 feet. In some instances
we used a five times longer scale, making the spectrum 75 feet.

There is still another series of determinations by Angstrém,*
but the original memoir is not accessible to us, and the extract
in this Journal does not admit of direct comparison with Kireh-
hoff’s scale.

Investigation.

$16. It can hardly be assumed that the determinations of
Pliicker are as accurate as those of Ditscheiner; the latter are,
as will be shown, not always reliable in the last figure. Hence
the agreement between observation and our calculation 1s in
most cases astonishingly close; thus for hydrogen, where d=
169 there is only one single deviation, and this amounts to only
three units; the chlorine spectrum shows as good as no devia-
tion at all, only one unit for d=47 on a range of 700. It is similar
for bromine, oxygen, nitrogen, and mercury. Only iodine devi-
ates for one single line (9) more than is proper, especially as d
is only 8; but then this being the only instance, it may be due
to a greater error in the observation of 6.

It may perhaps be objected, that only few lines are taken for
each element. But we have taken ail lines for which determin-
ations could be found, and though they may be few in number,
they are ranging through the greater part of the spectrum. —

uming that the other metalloids will correspond in this as
they do in all other respects, we may express the above by the
following law: the wave-lengths of the dark lines in the spectra of
the several metalloids differ from one another by simple multiple of @
certain number, d, peculiar for each element, and the spectra of the .
binary compounds given do not show so simple multiples, but
the differences are yet expressible in multiples of a certain num-
ber for each compound.
_ The above law is substantially the same as the laws deduced
in the preliminary investigation. ,
17. In all the foregoing tables we have made use of Pliickers
observations, which are only known to us in their final result,
The following values of W will be taken from Ditscheiner, and
as his memoir js at hand, we may first ascertain the degree of
accuracy of his observations.

For Kirchhoff’s line 1834:0 he finds W=5040-0 from 18 de-
terminations, gonging from 5039°3 to 5041-4, showing a range
of 2°1 (page 326, 1. ¢.}

For ate 6 he finds W=5165'8 from 13 determinations,
ranging gr et 1 to 51668 or a range of nearly two of our

units (page 8

By having more accurate data, the intervals become more sim-
plified, especially in regard to the consolidating of groups of
lines, as has been shown in the preceding paragraph.

In the synopsis of the calcium spectrum given on page 35 of
our first article (this Jour., vol. xxxvili) the deviations amount
to fully

a=0"" 0000030,

while in our present article the greatest deviation is only (§ 18)
a’=0™"-0000001

or a: a’=30: 1, only one-thirtieth of the previous one.

This comparison might be considerably enlarged—but the
preceding is enough to show that far from disappearing by
closer approximation and more accurate data, the laws there. ,
enunciated are becoming even more prominent and unmistak-
able in proportion as the data of observation have become more
rigorous and reliable. It may therefore be hoped that contin-
ued investigation will tend to the better establishment of the
laws referred to.

And it is in view of this greater confidence we are permitted
to bestow on the regular distribution of the dark lines that we
will venture upon the dangerous ground of a theoretical expla-
nation of these wonderful facts and mysterious laws. e im-
portance of spectral a in a practical point of view is es-

little detail on this difficult and obscure, but most important.
int.

_ $26. Origin of the dark lines—The mere aspect of the dark
lines in any spectroscope conveys almost a moral conviction to
the mind that they are allied in their origin to the dark lines of
interference produced by thin plates and the like; for example,
Talbot's interference phenomena produced by the interposition
of a little’ piece of glass or mica between the eye and the ocular
of a telescope directed to a spectrum, or Baden Powell’s lines
produced by a glass plate immersed in a prismatic trough fill
with cassia-oil, ete. :

This idea is already old, and I know of no definite refutation
thereof. The lines produced by the vapors of iodine, bromine,
hypochlorous acid and others, are closely allied to the regular
spectral lines and the above lines of interference. Bottger

the yellow and the violet @ very large number of equidistant dark
hin

e have furthermore proved that though not ail lines are
present, corresponding to each successive equal interval, still all
the known lines occupy positions in exact avcordance with the
equal intervals, that is, the dark lines are as if from the whole
number of exactly equidistant lines some had been blotted out or at
least obscured by other causes.

From all this, both the experimental and our theoretical evi-
dence, we conclude, that the dark lines are produced by interference.
We will now see whether we can account for some other pecu-
liarities of their distribution by means of this hypothesis.

Erman, in his investigation of the absorption lines of iodine,
bromine, etc., has shown that such lines produce y a plate of
mica are the closer together, the thicker the plates, and that they
are farther apart in the violet than in the re

ture, becoming more numerous with higher temperature—the
dark lines would be as changing as the arrangement of the atoms.

ut we know the spectral lines to be permanent and immutable,
aS we suppose the atoms themselves to be.” We therefore must

tra of the elements are the result of the interference of at most three

systems of interferences determined by the three dimensions of the
oms,

We shall now compare some of the points involved herein to
the results of observation laid down in the preceding paragraphs.
7. Is the difference constant throughout the entire spectrum ?

or are the lines farther apart in the blue end of the spectrum,
Where the wave-length is smaller? The values of D obtained
for the iron groups are: D in the yellow 13°16, in the green

more extended research is required. But we may safely affirm
that in case any such variation is actually proved it will be found
to be very small. :

groups of lines. Thus iron group I numbers 18 lines ranging
through nearly 100 mm. of Kirchhoff’s scale. ° be-
fore, not all lines are actually observed—but that may be due
to the coéxistence of the several systems caused by the several
dimensions of the atoms, whereby also a variation in the inten-
sity of the lines would be produced.

$29. Influence of the dimension of the atoms.—The greater d,
the closer must be the dark lines. If this theoretical result be
applied to the elements, considering their dimension as d, it
would follow, if we adopt the hypothesis of one element, there-
by measuring volume by the weight of the atom, that the lines |
must be generally the closer the greater the atomic weight of the ele-

ments,

In the following table A is the atomic weight taken from
Will’s Jahresbericht for 1863 as copied in the Smithsonian Re-
port for 1864; d is the interval as found in the preceding para-

8:

We notice first the great intervals of the metalloids as com-
ared to those of the metals; also in general a greater interval
or smaller atomic weight. This is the more conclusive for simi-

elements, as exemplified in the chlorine group. :

€ can not expect a more close agreement, for the dimensions

and not the volume, proportional to the atomic weight, decide
the distribution of the dark lines.

ut the dimensions can only be found by for a. moment _ac-
cepting our hypothesis of the construction of the elements. We
hope that the preceding will induce the reader to approach this
question, ;

We cannot here go into any detail as to the relation of these —

formule to the numerical relations discovered by Carey Lea,
Dumas and others; we hope soon to be enabled to publish our
labors on the constitution of the elements. Neither can we here
discuss these formule in the sense of the mechanics of atoms
deducing the physical and chemical properties of the elements
from these formule; these interesting relations also we must
delay till some future, but I hope not a very distant, time. Nor
is this the place to discuss the few slight device noticed.
‘Our aim here i is to make use of these our old formule in spectral
analysis.

First, seca we notice that the alkaline-earth metals are quad-
ratic, so that their 3 shots are the result of two systems only of
lines. Further, having a common base (2), they must show one
set of differences, either absolutely or nearly equal—which, until

_ we havean analytical investigation hereof, or fuller experimental
results, we cannot decide. But this is precisely what has been
found in §22, where the intervals were found respectively to be

We might now discuss the occurrence of the dimension-figures
of the atoms in the corresponding spectra as intervals ; suc for

ces are pretty numerous, but a fuller stock of still more reliable
measurements will be required for the metallic spectra

distance d of lines, according to the given tables.

The other dimension of this group is 8, and is fairly repre-

sented in the intervals. Thus we have in the spectrum of todine,
neglecting the two extremes which are not necessarily complete,
the intervals (see § 7)

$31. Conclusion.—In the preceding we have found, by means
of the most accurate determinations of Ditscheiner and Pliicker,
that for the thirteen elements considered (viz., hydrogen, oxy-
gen, nitrogen, chlorine, bromine, iodine, mercury, sodium, mag-
esium, calcium, stro ntium, barium, iron, and besides four com-
botndsy - the dark lines of the elements are equidistant throughout
the spectrum, but of varying intensity, many not being observed (or
observable) at all; the oe between the observable lines are ex-
Pressible as simple multiples of the ssid distance indicated by all.

III. How does carbonate of lime act upon a solution of chiorid of
magnesium ?—I boiled for sixteen hours two grams of finely pul-

eblorid of caleium; while freed magnesia enters into com-
bination with the main bulk of its chlorid, forming a soluble

oxychlorid. The duration of treatment and the temperature
influence, to some extent, the degree of change, which in itself

an examination proved that only 0°0246 grams of oxyd of cal-
cium, equal to 0:0470 chlorid of calcium were left in the solu-
tion; while the missing lime had been replaced by magnesia: or,
in other words, the chlorid of calcium, originally in solution,
had been replaced by chlorid of magnesium. The excess of
carbonate of magnesia employed for the operation, as left upon
the filter, contained 06480 grams carbonate of lime (=0°7193

under proper circumstances, quite rapid and complete. There

tities in which they happen to mix. As carbonic acid gas in-
creases the solubility of a number of compounds here under con-
Sideration, its presence either as gas, or in the form of a bicart

In the following final arrangement of my quantitative analyt-
ical results (see page 216), I favor No. I. in each case as the form
best illustrative of the teachings of my investigations; for I am
inclined to believe that the least objectionable basis for arranging
analytical results, is to state them as they are obtained from an
analysis of the solid residue left after a careful evaporation to
dryness at common temperatures. In taking this view I am
fully aware of the various changes of affinities which the altera-
tions in temperature and concentration, in many instances, exert.
Nos. II. and III, in each corresponding case, represent the same
analysis in forms based upon views differing from those adopted
in this paper. ‘

stances where the gypsum and carbonate of magnesia exceed
the chlorid of sodium, or under the influence of a certain higher
degree of temperature, the product will be sulphate of soda,
chlorid of magnesium, carbonate of lime, and sulphate of mag-
nesia. The essential difference between the brine and the spring wa-
ters consists, as has been noticed, in the fact that the former contains
_ chlorid of culeium instead of carbonate of lime contained in the lat-
ter. The presence of chlorid of calcium in the brines practically
excludes all sulphates, except sulphate of lime. A sufficient
amount of carbonate of magnesia, added to the Onondaga brine,
displaced quite readily the chlorid of calcium, by forming chlorid
of magnesium and carbonate of lime; and would have displaced,
finally, at the expense of the gypsum produced (if exceeding the
chlorid of calcium in amount), sulphate of soda and chlorid of
magnesium, provided an excess of free carbonic acid were secured
during the whole action. Free carbonic acid never fails to

present in the cases presented. The changes which must occur
when the brine and spring waters become mixed are, in view of
the preceding statements, quite obvious. The sulphate of mag-
nesia and sulphate of soda of the waters act upon the chlorid of
calcium of the brine, producing sulphate of lime, and the chlo-
rids of magnesium and sodium; while the carbonate of lime
contained in the spring waters enter simply into the mixture.
The observation, that in several instances carbonate of lime has
been found covering the crystals of gypsum separated in the
wooden vats during the concentration of the brine by solar heat,
may find its proper explanation in the temporary existence of

rectly underlie our area of red shale—if bearing salt water, etc.,

mation, it must be admitted, cannot be overrated when engage
in tracing the origin of our brines. All that is at present known
of the Onondaga brines and their sources may be summed up in
the following statements: .

. The depressions in the Onondaga Shales are filled, in some
localities, to an extent of nearly three to four hundred feet in
depth with a diluvial deposit (detritus), varying from the coarsest
gravel to the finest drift sand.* :

2. The layers of coarse gravel and fine sand alternate without
any distinct order or extent. : :

3. The gravel has frequently been formed into a conglomerate
of great hardness, commonly called hard-pan—an impermeable
layer which intersects, more or less efficiently, the various strata
of the loose material. Hey

or loamy sand, covers, frequently, to a considerable extent, and
to a depth of from 30 to 40 feet, the lower diluvial deposits.

5. The Onondaga red shale has been struck everywere, when
the boring was continued beneath the brine-bearing drift masses;
near the eastern embankment at from 90 to 180 feet ;—toward
the middle of the valley, between Salina and Geddes, at about
882 feet.

brine proper makes its appearance at about 300 feet
below the level of the surface.

. The brine rises by means of boring and tubing to the level
of the lake surface or within from 10 to 15 feet of it; the de-
gree of its rise depends apparently on the specific gravity of the
brine e most concentrated brine remains lowest.

8. The yield of a well, independently of the concentration of
the brine, depends on the size of the gravel or sand around the
lower termination of the tubing.

9. The brine does not increase or decrease in strength during
the winter season, when no pumping takes place; its temper-
ature is from 52° to 58° F.

10. The deep wells bear tlie heavy drafts of brine during the
summer season without suffering in strength, while the shallow
wells decline.*

11. The lowest depth does not, in all cases, guarantee the most
concentrated brine.

12. The red shale apparently bears irregularities of stratifica-
tion independent of the peculiar form of a basin.

of the lowlands—at Green Point—contains veins of gypsum 1n-
terspersed with specular iron ore.

occurrence of the peroxyd of iron asa pseudomorph of
chlorid of iron in this local outcrop of the red shale is deserving
of some attention. The peculiar manner in which the gypsum
and that ore present themselves, sometimes in veins along side
of each other, sometimes the latter surrounded and enclosed by
the former, (besides the resemblance between some of the adjoin-
ing gypsum to the hardened masses of gypsum separated from
its boiling solution in salt water,) are facts which seem to point to
the existefice of some peculiar local disturbance due to subterra-
nean heat. The presence of serpentine at James street height,
and the elevation of the localities where casts of chlorid of so-
dium have thus far been found, may also bear some relation to

When a burette contains a portion of liquid, it isa matter of —
great nicety to determine the division or fraction of a division to
which the surface of the liquid corresponds. To save the labor
of holding the paper with the lower half blackened behind the ©

parallel slits in it so as to form a band, — ‘being slipped over
the burette, the card maintains its own positi The use

the accuracy desirable. Bunsen, on the contrary, uses a cathe-

assumed to mark the surface of the liquid, will be found to

that even the sli ightest movement of the eye produces a change
in the position of the line which gives a difference in results

Ving a portion of the liquid, he cannot be certain that hise eye akan
occupied the same relative: position in both cases, unless he takes
due precautions. Every observer does not possess a cathetom-
eter, and the following arrangement which is of extreme —
city, will be found to answer every purpose

378 M. C. Lea on some new Manipulations.

A slip of wood is provided 5 inch thick, 14 inches wide, and
- 2feetlong. A piece of card about 4 inches square has two par-
allel slits made in it at one end, one slit half an inch from the
top, the other the same distance from the bottom. These slits
are of such a length as just to permit the piece of wood to be
passed through them, presenting the appearance represented in
the margin.
To make a reading, the half black card previously spoken of is
slipped over the burette, and the line of separation between the
white and black is brought one millimeter below the black line
which marks the surface of the liquid. The instrument repre-
sented in the margin, is then placed beside the burette, 5,
the lower end resting on the table, and the card is raised

or lowered until the edge B exactly corresponds with vi
the line of separation in the black and white card. The
stick is then drawn toward the observer, the end B ns

still resting on the table, and the observer places his eye
so as to keep the line B in range with the line of sep-
aration, and makes the reading.

Another precaution which I regard as essential, and
which I have nowhere seen mentioned, is the follow-
ing: The observer should place himself where he has
a strong side light. The half black half white card must
not be placed parallel to the eyes of the observer, but
must be turned toward the light, so as to make an an-°
gle of 45° with the line of vision. In this way a strong light
is reflected from the card and thrown through the burette in a
manner greatly conducive to clearness of vision, and the black
line which marks the surface acquires a peculiar sharpness. —

I cannot better illustrate the necessity of these precautions,
(especially the use of the little instrament above described, and
which may be termed the eye adjuster) than by the comparison
of the following results obtained without them and with them.

Comparing the first and second columns, that is, the first set

then passed over the open end of the stem of the funnel: this
piece ma sian: be several feet i in length, or it may be shorter,

tube is closed with the finger and the funnel is quickly inverted
in the vessel containing the mixture to be filtered. The other
end of the tube hangs down into a convenient vessel placed on
the floor. If it is desirable that water
shall not be added to the mixture, the
funnel is inverted empty, and the air is
drawn out by a pipette inserted into
the open end of the india rubber tube.

It is evident that this arrangement is
a combination of filter and siphon, and
the pressure of the column of water in
the longer leg of the siphon expedites
the operation very much and leaves the
solid portions much drier than ordinary.
As the liquid begins to be exhausted,
the solid portions are to be gathered
round the funnel with aspatula. When
the filtrate ceases to run, the funnel is
left full:—in order that this may not
return upon the solid matter, the funnel is lifted out of the ves-
sel and the broad end quickly turned uppermost, when the con-
tents of the funnel flow down the tube.

When a precipitate is to be well washed this mode is evidently
not applicable, although a tolerable washing is perfectly practi-
cable. But when liquid and solid matters are to be quickly sep-
arated on a large scale, it is very useful. When masses of small
crystals strongly retaining the mother water, are to be freed
from it, this may be done more quickly and more thoroughly
than by ordinary filtration. Many other cases will readily sug-
gest themselves. For example, when potash has been boiled
with lime to render it caustic in large vessels, it is usually drawn
off with a siphon into bottles and left twelve to twenty-four
hours to settle, and then must be carefully decanted. It is far
less trouble to filter it in the above manner in the act of re-
moving it by asiphon. And so with many of the rough opera-
tions which occasionally present themselves in the laboratory,
and which are upon a scale rather exceeding the capacities of
ordinary filtering funnels.

Tn the i pha of crystals from the mother water, muslin
. will general ly give a clear filtrate. In other cases it is necessary

to place a piece of filtering paper inside the muslin. The paper
must of course be of size sufficient to be secured by the twine at
the neck of the funnel. But the force with which the column 0
water acts upon the muslin over the mouth of the funnel, draws
it to a concave shape, and sometimes breaks the paper. 1°
avoid this, the paper may be folded so as to fit the inside of the
funnel, turning the edges oyer and securing them as before de-

scribed. ‘T'o do this requires a little dexterity; the diameter of
the paper must be six or seven times that of the mouth of the
funnel, it must be folded across in two rectangular directions in
the ordinary way, then opened and reversed and from opposite
points in the edges folded some distance past the middle. The
funnel is then passed into it and the edges are passed round
the neck of the funnel, the muslin is next placed over the pa-
per and the whole is secured round the neck with cord.

be derived from it, and to be transformed for the object in view.
I found it necessary to exercise this economy from the very out-
set, and further on, at each and every step of all the processes
and operations involved in the development and transformation
of the power. One of these steps was the production of the
galvanic current within a full circuit, from the free electricities
of the poles of the open battery. A given quantity of electri-
city, in a galvanic current, will always, generally viewed, produce
the same amount of electric process. But the free electricities
requiring time for motion i combination (to use some kind of
expression for the details of the electric process), remain during
this time, subject to the influences of induction and the molecu-
lar qualities of the conductors. There may, consequently, occur
something like a diffusion of the electricities, before the electric
process is completed, and. it is most probable that the direction
of the electric process therefore, will not remain one and the
same for the whole quantity of electricities, but that one part of
the electric process will be executed in directions varying from
the main direction, thus diminishing the actual effect of the pro-
cess; and that the amount of this part, respectively the amount
actually disposable, will depend upon and vary with certain cir-
cumstances. Now, as the electro-magnetic effect of the galvanic
current is plainly and invariably governed by the direction of
the electric process, it becomes evident that the amount of elec-
tro-magnetism to be derived from a given quantity of electrici-
ties, and available for any practical purpose, depends entirely
on that part of the electric process which, at last, is going on in
the main direction, and which is only a certain percentage of the
whole electric process.

These considerations compelled me to be watchful, and this
the more as I met with but one remark (by Buff, if I remember
rightly) directly pertaining to this question. He found the elec-
tro-motive force of the battery increasing with the decrease of
the measured intensities of the current. This circumstance, 1
true, would justify my views of the matter, and naturally ihe

affect the economical applications of the galvanic current. ‘The _

lution of sulphate of zine) and strong nitric acid, or a properly
acidulated solution of bichromate of potash instead.

My method of experimenting was as follows. After prevent-
ing the conducting wires from affecting the tangent compass,
and determining the intensity of the current within the shortest
circuit possible, increasing length of platinum wire was, without
opening the circuit, introduced into it. The reasons for not
opening the cireuit after each observation, were: 1, the time re-
_ quired for every observation after the circuit had been opened ;

2, within the electro-magnetic machine, a similarly gradual
change of resistance is effected, by means of the brake; 8, the
rheochord is just designed, partly, to relieve of that tedious
practice of opening the circuit every time a new resistance is in-
troduced, and no objections have been raised, so far, against its
proper use.

T'o ealculate the constants of the battery I followed the com-
mon rule, combining the highest intensity within the shortest
cireuit, with each and every lower intensity. Let I, and [,,

I think nobody can overlook the general increase of the inter-
nal resistance of every cell, except No. 6, with the increase 0
the external resistance, or with the decrease of the observed in-
tensity. The sum of the mean resistances of all the six cells is

given in tables 1, 111, Iv, and v. Since, according to the form-
ula HE=RI,, both the electro-motive force and the internal re-
sistance maintain the same relation, I calculated for these, and
all the following tables, only the internal resistance. Table 111

shows an increase from 2°98 to 5°52, not quite as much as table
I; though the direct intensity is about the rene while the ex-
ternal resistance has been increased very much. ‘Tables 11 and

Iv plainly demonstrate, as a general rule, that the increase of the
internal resistance becomes less remarkable when the direct in-
tensity of the battery is low. This rule, however, has its pei
tions, and table v exhibits a very remarkable case. The direc
intensity of this battery is less than in table u, still nes one
of the internal resistance is much greater than in this t

These results vexed me the more, since I eudentonk the ex-
periments mainly for practical purposes. e experiments de-
layed my proposed investigation, and I could not anticipate any
direct profit. I therefore : concluded to give up, for the pres-
ent, determining the constants of the battery, as they were not

As table v shows, the resistance of the copper wire “ caleu-
lated in this manner, increases with the decrease of the observed
intensities, just the same as the internal resistance did. - d no
limit being fixed, there could not be placed any reliability in’
any one of these calculated resistances, nor could I, with such a
method, determine at all any resistance, under circumstances
similar to those I proposed to try within the electro-magnetic
machine. I now was compelled to investigate the matter at
once,

As mentioned above, the reason for the increase of the inter-
nal resistance may be the relations existing between the intensity
of the current, the heat developed by it within the circuit, and
the influence of te temperature upon the resistance of conductors.
Jadeed, the heating of the platinum wire makes our unit of re-
sistance greater than the resistance of a unit of length of the
wire at common temperature. And the liquids in the cup being

3386 H. Haug on the Electro-motive Force

heated, thereby offer Jess resistance. The internal resistance
being diminished, and measured with an increased unit, will, of
course, appear smaller than at low intensities. But knowing this,
every body ought to foresee the general increase of the constants
of the galvanic current with the decrease of its intensity, instead
of neglecting this fact entirely, or underrating its importance,
and treating any variation of results simply as errors of observ-
ation.

whole, it is however just to remark, that it is indeed open to ob-
jection on a general ground, since all the experiments, the ratio of
increase of the resistance of conductors with increase of temper-
ature, as commonly understood, is based upon, must have been
influenced, and their results augmented, by any other reason of
such increase of resistance, if there be any other reason at all.

_But this interpretation of the fact in question is liable to more
direct and more conclusive objections, and I could not feel sat-
isfied with it at all. In the first place, there were the expert
ments of table v, which seemed directly to contradict any such
explanation. The ratio of increase of the internal resistance, the
copper wire included, from 8°86 to 15-71 is oe 223718

coincident with Fraunhofer’s F.* At rather more than one-fourth

liant line was seen. Botti these lines were narrow and sharply

Besides this constitution, which it possesses in common with
the sun and the stars, there must exist the source of the gaseous

8 Pegasi, and the absorption spectrum of the remarkable object
described in this paper. The purely speculative idea presents
itself from these observations, that hydrogen probably plays an
important part in the differences of physical constitution which
apparently separate the stars into groups, and possibly also in
the changes by which these differences may be brought about.*

ation of the food, and the mechanical work to the oxydation of
the muscles.

This doctrine, first promulgated, the speaker believed, by
Liebig, occupies a prominent position in that philosopher's justly
celebrated ‘Chemico-Physiological Essays.’

In his work entitled ‘ Die organische Chemie in ihrer Anwen-
dung auf Physiologie und Pathologie, Braunschweig, 1842,’ Lie-
big says, ‘ All experience teaches that there is only one source
of mechanical power in the organism, and this source is the
transformation of the living parts of the body into lifeless com-
pounds.... This transformation occurs in consequence of the
combination of oxygen with the substance of the living parts of

e body.” And again, in his ‘Letters on Chemistry, 1851,’
p. 866, referring to these living parts of the body, he says, ‘“ All
these organized tissues, all the parts which in any way manifest
force in the body are derived from the albumen of the blood;
all the albumen of the blood is derived from the plastic or san-
—- constituents of the food, whether ‘animal or vegetable.

t is clear, therefore, that the plastic constituents of food, the
ultimate source of which is the vegetable kingdom, are the con-
ditions essential to all production or manifestation of force, to
all these effects which the animal organism produces by means
of its organs of sense, thought, and motion.” And again, at
page 374, he says, “The sulphurized and nitrogenous constitu-
ents of food determine the continuance of the manifestations of
force; the non-nitrogenous serve to produce heat. The former
are the builders of organs and organized structures, and the pro-
ducers of force; the latter support the respiratory process, they
are materials for respiration.”’ ;

This doctrine has since been treated as an almost self-evident
truth in most physiological text-books; it has been quite recently
supported by Ranke ;’ and, in his lecture ‘On the Food of Man
in relation to his Useful Work, 1865,’ Playfair says, page 37,
“ From the considerations which have preceded, we consider
Liebig amply justified in viewing the non-nitrogenous portions
of food as mere heat-givers. .. . While we have. been led to
the conclusion that the transformation of the tissues is the source
of dynamical power in the animal.” At page 30 he also says,
“T agree with Draper and others in ssi fo the contrac-
tion of a muscle due to a disintegration of its particles, and its
relaxation to their restoration... . All these facts prove that
transformation of the muscle through the agency of oxygen 38

view of the present relations of chemistry to animal life, pub-
lished in March last,* Odling says, page 98, “ Seeing, then, that

muscular exertion is really dependent upon muscular oxydation,
we have to consider we should be the products, and what the

value of this oxydati ... And again, page 108, “The
slow oxydation of so muc mh carbon and hydrogen i in the human
body, therefore, will —<— produce its due amount of heat, or

force liberated by the stl of the st a and hydrogen of
fat is expressed solely in the form of heat, the ‘combustion of -

not the material by the chemical ge re which mi an igcohy work
is produced.” He showed that the 15 lbs. of dry muscles of a
man weighing 150 Ibs. would, if their mechanical work were
due to their chemical change, be completely oxydized in eighty
days, the heart itself in eight days, and the ventricles of the
eart in two and a half days. After endeavoring to prove by
physiological arguments that not one per cent of the oxygen ab-
sorbed in the lungs could possibly come into contact with the
substance of the muscles, Mayer says, ‘The fire-place in which
this combustion goes on is the interior of the blood Vessels, the
blood however—a slowly-burning liquid—is the oil in the r Pe
of life. . . . Just as a plant-leaf transforms a given mechanical
effect, light, into another force, chemical difference, so does the

motion two aie are necessary—the conveyance of combusti-
ble, substances to the muscle by the blood, and the access of
oxygen by respiration. He concluded that the chief combusti-
ble substance so used was fat. A century before —— iso-
lated oxygen, ‘Mayow-m was aware of its existence in the air, in
nitre, and jn nitric acid; he knew that ieabation: is supported
by the oxygen of the air, and that this gas is absorbed in in the

lungs by the blood, and is absolutely necessary for muscular
activity.

For two decades this doctrine sank into oblivion; and it is
only within the last two years that it has been again advanced,
chiefly by Haidenhain,* Traube, and, to a limited extent, by
Donders.’

Experimental evidence was, however, still wanting to give

missing link in the following words: “The question now arises
what quantity of heat is generated when muscle is burnt to the
products in which its constituent elements leave the human
body through the lungs and kidneys? At present, unfortu-
nately, there are not the experimental data required to give an
accurate answer to this important question, for neither the heat
of combustion of muscle nor of the nitrogenous residue (urea)
e is known.” Owing to the want of these data, the
numerical results of the experiments of Fick and Wislicenus
are rendered less conclusive against the hypothesis of muscle
combustion than they otherwise would have heeti while similar
determinations, which have been made by Edward Smith,
Haughton, Playfair, and others, are even liable to a total misin-
terpretation from the same cause.
_ The speaker stated that he had supplied this want by the ca-
lorimetrical determination of the actual energy evolved by the
combustion of muscle and of urea in oxygen. Availing him-
self of these data he then proceeded to the consideration of the
problem to be solved, the present condition of which might be
thus summed up:—It is agreed on all hands that muscular

power is derived exclusively from the mutual chemical action
of the food and atmospheric oxygen; but opinions differ a
whether that food must first be converted into the actual orga
ized substance of the muscle, before its oxydation can give ri
to mechanical force, or whether it is not also possible that mus-
cular work may be derived from the oxydation of the
which has only arrived at the condition of blood and not of or-
ganized muscular tissue.

The importance of this problem can scarcely be overrated ; it
is a corner-stone of the phymclogiea) edifice, and the key to the

phenomena of the nutrition of animals. For ae isi tee so-
lation the following data require o be determined :
e amount of force or actual pieces generated by the
ae of a given amount of muscle in the body.
The amount of enagtilig force exerted by the muscles
of the body during a given
3d. The quantity of eda iad in the body during the
same time.

If the total amount of force involved in muscular action, as
measured by the mechanical work performed, be greater than
that ioe ye could possibly be generated by the quantity of muscle
oxydized during the same time, it necessarily follows that the
power of the muscles is not derived ae from the oxyda-
tion of their own substance.

As regards the first datum to be determined, it is necessary to
agree upon some unit for the measurement of mechanical ag
The unit most commonly adopted is that represented by the
lifting of a kilogram wei sht to the height of one meter. The
researches of Joule and Mayer have connected this standard

body to this height represents 64,000 meterkilograms of work;
that is, the labor necessary to raise a kilogram weight to the
height of 2 meter 64,000 times. ;

In order to estimate the amount of actual energy generated
by the oxydation of a given amount of muscle in the body, it is
necessary to determine, first, the amount of actual energy gene-
rated by the combustion of that amount of muscle in oxygen,
and then to deduct from the number thus obtained the amount
of energy still remaining in the products of the oxydation of
this quantity of muscle which leave the body. Of these pro-

quantity (2 liters) of water. The determinations were made
with this instrument in the following manner:—19%5 grams of
chlorate of potash, to which about one-eighth of peroxyd of
manganese was added, was intimately mixed with a known
weight (generally about 2 grams) of the substanee whose poten-
tial energy was to be determined, and the mixture being then
placed in the copper tube above mentioned, a small piece of cot-
ton thread, previously steeped in chlorate of potash and dried,
was inserted in the mixture. e temperature of the water 1n
the calorimeter was now ascertained by a delicate thermometer ;
and the end of the cotton thread being ignited, the tube with its
contents was placed in the copper bell and lowered to the bottom
of the water. As soon as the combustion reached the mixture
a stream of gases issued from numerous small openings at the
lower edge of the bel! and rose to the surface of the water—a
height of about 10 inches.

At the termination of the deflagration, the water was allowed
ree access to the interior of the bel, by opening a stop
connected with the bell by a small tube rising above the surface

quickly established. The temperature of the water was again
carefully observed, and the difference between this and the pre-
vious observation determines the calorific power or potential en-
ergy, expressed as heat, of the substance consumed.

form an amount o < equivalent, in round numbers, to the
lifting of a weight of 15 lbs. to the height of one inch. In per-
forming this work the gases are cooled, and consequently less
heat is communicated to the water of the calorimeter. Never-
theless, the loss of heat due to this cause is but small. Under the
actual conditions of the experiments detailed below, its amount
would only have inereased the temperature of the water in the
ealorimeter by 0°07 C. Even this slight error is entirely elim-
inated by the final eorrectiori which we have now to consider.

402 E. Frankland on the Source of Muscular Power.

It is evident that the above determination of the actual energy
developed by the combustion of muscle in oxygen represents
more than the amount of actual energy produced by the oxyda-
tion of muscle within the body, because, when muscle burns in
oxygen its carbon is converted into carbonic acid, and its hydro-
gen into water; the nitrogen being, to a great extent, evolved
in the elementary state; whereas, when muscle is most com-
pletely consumed in the body, the products are carbonic acid,
water and urea; the whole of the nitrogen passes out of the
body as urea—a substance which still retains a considerable
amount of potential energy. Dry muscle and pure albumen
yield, under these circumstances, almost exactly one-third of
their weight of urea, and this fact, together with the above de-

of urea, enables us to deduce with certainty the amount of ac-
tual energy developed by muscle and albumen respectively when
consumed in the human body. It is as follows:—

We have thus ascertained the first of our three data, viz., the
amount of force or actual energy generated by the oxydation of
a given amount of muscle in the body; and we now proceed to
ascertain the second, viz., the amount of mechanical force ex-
erted by the muscles of the body during a given time. For this
purpose we have only to avail ourselves of the details of Fick

viz., the height of the summit of the Faulhorn above the level
of the lake of Brienz multiplied by the weight of the body;
the former reckoned in meters, the latter in kilograms. The

weight of the body with the equipments (hat, clothes, stick)

E.. Frankland on the Source of Muscular Power. 408

amounted to 66 kilograms in Fick’s case, and 76 in Wislicenus’s,
The height above the Faulhorn above the level of the lake of
Brienz is according to trigonometric measurements, exact
1966 meters, Therefore Fick Solana eta 129, 096 and Wislice-
nus 148, 656 meterkilograms of muscular ork,”

But in addition to this measurable axiardal work there is an-
other item of force “which can be expressed in units of wor
and though its value cannot be quite accurately calculated, <0
a tolerable approximation can be made. It consists of the foree
consumed in respiration and the heart’s action. The wor
formed by the heart has been estimated, in a healthy full-grown
man, at about 0°64 meterkilogram™ for each systole. During
the ascent, Fick’s pulse was about 120 per minute. That gives
for the 55 hours of the ascent an amount of work which may
be estimated at 25,844 meterkilograms, entirely employed in the
maintenance of the circulation. No attempt has ae age ame
to estimate the labor of respiration One of u n,
however, in the second edition of his i Medical Physics” a 206),

that Donders’s well-known investigations concerning the condi-
tions of pressure in the cavity of the thorax gi give sufficient data
for such an estimate. He has there shown that the amount of

which gives, according to this estimation, an amount of ee ge

for Wisliootue s amount of w ork, as far as it is sable to cal-
culate it, a total of 184,287 Tatar sloarravin

“Besides these estimated (and certainly not agar
items, there are several others which cannot be even approxi-
mately calculated, but the sum of which, if it Paar bs obtained,
would probably exceed even our present large total. We will
try to give at least some sort of an account of them. It must
first be remembered that in the steepest mountain path there are
occasional level portions, or even descents. In ade i such |
places the muscles of the leg are exerted as they are in ascend-
ing, but the whole work performed is eenifovined back into
heat. The same force-producing process, however, must
going on in the muscles as if work were being performed which |

did not undergo this. transformation. In order to make this
point yet clearer we may take into consideration that the whole
work of the ascent, only existed temporarily as work. On the
following day the result was reversed; our bodies approached

circumstance that during the period of abstinence, the secretion

the only other mode of exit for this element is through the
feces. Now the proportion secreted through the feeces has been
estimated by Ranke at about one-twelfth of that in the urine;
but inasmuch as all experiments on the subject tend to show
that this alvine nitrogen is, as voided, a constituent of un-oxyd-
ized compounds, that is, of compounds that have not yielded up ©
their force, it has no claim upon our attention.

There is still another circumstance which requires to be taken
into consideration before we proceed to apply our three data to
the solution of the problem before us. It is this:—Is it possible
that at the termination of the ascent of the Faulhorn there might

sential work in ascending, have been estimated by Weber to
weigh in both legs 5’8 kilograms, and if we assume that before
the ascent these muscles contained ‘06 per cent of creatin, while

ter the ascent the percentage had increased to ‘14 per cent,
then the amount of creatin thus exceptionally retained would
amount to 4°64 grams, which would be derived from 84 grams
of muscl

e. :

The speaker had been unable to determine the calorific effect
of creatin, and consequently the actual energy developed by the
transformation of muscle into creatin; for, although he was
kindly furnished with an ample supply of this material by Dr.
Dittmar, yet all attempts to burn it in the calorimeter were fruit-
less. n when mixed in very small proportions with chlorate
of potash and other combustibles of known value, the mixture
invariably exploded violently on ignition. Although actual de-
termination thus fails us, there can be no doubt that the trans-
‘or of muscle into creatin and other non-nitrogenous pro-
ducts must be attended by the liberation of far less actual energy
than its transformation into urea, carbonic acid, and water. To
be convinced of this, it is only necessary to compare (under
equal nitrogen value) the formule of muscle, creatin, and urea,

sesses no thermal value, and that each atom of oxygen destroys
approximately the thermal effect of two atoms of hydrogen.

Thus it is evident that the amount of creatin exceptionally
retained in the system could not greatly affect the result of the |
experiment as regards the possible amount of actual energy de-
rivable from the metamorphosed tissues during the ascent;
firstly, on account of the small quantity of creatin so retained,
and, secondly, because creatin still contains about one-third of
the potential energy of the muscle from which it is derived.

muscles of the legs contained at the end of the ascent eleven
times as much creatin as was present in them before the ascent,
In the above tabular statement of results provision has been
made for this allowance by adding together, on the one hand,
the amounts of nitrogen secreted during the ascent and six
hours after it, and, on the-other, the weights of dry muscle cor-
responding to these two amounts of nitrogen.

Having thus far cleared the ground, let us now compare the
amount of measured and ealculated work performed by each of
the experimenters during the ascent of the Faulhorn, with the
actual energy capable of being developed by the maximum
amount of muscle that could have been consumed in their bod-
ies, this amount being represented by the total quantity of nitro-
gen excreted in each case during the ascent and for six hours
afterwards.

It is thus evident that the muscular power expended by these

power capable of being derived from this source even under
very favorable assumptions is, in both cases, less than one-half
of the work actually performed. But the deficiency becomes
much greater if we take into consideration the fact, that the ac-

energy developed within it, the remainder taking the form of
heat. Taking then this highest estimate of the proportion of
mechanical work capable of being got out of actual energy, it
becomes necessary to multiply by two the above numbers repre-
senting the ascertainable work performed, in order to express
the actual energy involved in the production of that work. We
then get the following comparison of the actual energy capable
of being developed by the amount of muscle consumed, with
the actual energy necessary for the performance of the work
executed in the ascent of the Faulhorn,

It has been already stated as a proposition upon which all are
agreed, that food, and food alone, is the ultimate source from
which muscular power is derived; but the above determinations
and considerations, the speaker believed, prove conclusively, first-
ly, that the non-nitrogenous constituents of the food, such as
starch, fat, &c., are the chief sources of the actual energy, which
becomes partially transformed into muscular work ; and secondly,
that the food does not require to become organized tissue before
its metamorphosis can be rendered available for muscular power ;
its digestion and assimilation into the circulating fluid—the blood
—beirg all that is necessary for this purpose. It is, however, by
no means the non-nitrogenous portions of food alone that are ca-
pable of being so employed, the nitrogenous also, inasmuch as
they are combustible, and consequently capable of furnishing ac-
tual energy, might be expected to be available for the same pur-
pose, and such an expectation is confirmed by the experiments
of Savory upon rats,” in which it is proved that these animals
can live for weeks in good health» upon food consisting almost
exclusively of muscular fibre. Even supposing these rats to have

These results a are in many instances fully borne out by expe-
rience. The food of the agricultural laborers in Lancashire
contains a large proportion of fat. Besides the very fat bacon
which constitutes their animal food proper, they consume large
quantities of i -called apple dumplings, the chief portion of which
consists of paste in which dripping and suet are Jarge ingredi-
ents, in fact cians dumplings frequently contain no fruit at all.

insects. The latter remarks, ‘‘ Many insects use during a period
in which very little muscular work is performed food containing
chiefly albuminous matter; on the contrary, at a time when the
muscular work is very considerable, they live exclusively, or

most exclusively, on food free from nitrogen.’ e also men-.

tions bees and butterflies as instances of insects performing enor-

mous muscular work, and subsisting upon a diet containing but
the merest traces of nitrogen

We thus arrive at the following conclusions:

1. The muscle is a oe for the conversion nit potential en-
ergy into mechanical for

The mechanical oie of the muscles is derived chiefly, if
not entirely, from the oxydation of matters contained in the

ood, and not from the oxydation of the muscles themselves.

In man the chief materials used for the production of mus-
cular power are non- nitrogenous; but nitrogenous matters can
also be employed for the same purpose, and hence the greatly
increased evolution of nitrogen under the influence of a flesh
diet, even with no greater muscular exertion

4, Like every other part of the body, the muscles are con-
stantly being renewed ; but this renewal is not perceptibly more
ee during great muscular activity than during comparative

uiescence.

5. After the supply of es albuminized matters in the

man to provide for the ssary renewal of the tissues,
the best materials for the prolate. both of internal and exter-
nal work, are non-nitrogenous matters, such as oil, fat, sugar,
starch, gum, &c.
a ®. The non-nitrogenous matters of food, which find thew way
ee the blood, yield up all their potential energy as actual en-
ergy; the nitrogenous matters, on the other hand, leave the body
a wih a portion (one-seventh) of their potential energy unex-

5. Laurite, a new mineral_—Wéuter has discovered among the fine-
grained platinum ore from Borneo, a new mineral, a sulphid of ruthe-
nium and osmium, to which he has given the name laurie. It occurs
in small grains of” a dark iron-black color, and high luster. Most of the
grains are true crystals, and Sartorius von Waltershausen has recognized
the mineral to have the form of the regular octahedron, in some instances
showing cubic, tetrahexahedral, and other planes. It has a distinct octa-
hedral cleavage, is brittle and yields a dark gray powder on pulveriza-
tion. Hardness, above that of quartz. Specific gravity, above 6 (6-99,
Sartorius), When heated it decrepitates, and B.B. is infusible, giving
first sulphurous and finally osmic aci ate Not acted upon by aqua
regia or by fusion with bisulphate of potash. Fused with hydrate of
potash in a silver crucible the mineral dissolves, yielding a green mass
on cooling. Analysis gave, ruthenium 65°18, osmium 3:03, sulphur

31°79. The osmium was determined by loss, and Wahler observes that
the ruthenium was not entirely free from this substance, so that the per-
centage of ruthenium is given somewhat too high, while that of the

composition of the mineral may be represented by the formula

vered ti succeeded in lar the topmost pinnacle,” which he repre-
sents as a “bare, rugged crag only large enough to stand upon.” y
found “a crater saints 3000 ft. below the top, from which a sulphurous
smoke ascended.”

The present year, we have more detailed accounts of two other ascents.
The first of these was made on the 26th of July, when “a party from
Portland reached the summit after six hours travelling from the snow

in

mond Tak a distance of 400 miles.” pbecr leap to the 1 maps, the act tual
distance between these peaks is but 260 miles. )

n the 20th of last August, another ascent was made by six gentlemen,
one of whom, Prof. Alphonso Wood, has a a detailed account of
the trip before the California Academy of Natural Sciences at their meet-

except where melted by hot gases and steam. “On the west side of the
crater is still an open abyss whence issue constantly volumes of strongly
sulphurous smoke. That there is heat there, is evident from the immense
depression in the snow about the place,—depressed not less than a thou-
sand feet below the snows which fill to the brim the other portions of the
ancient crater.” He measured the various altitudes by observing the boil-
ing point of water, and gives the following figures: “Summit of the Cas-
cade Range and foot of Mt. Hood proper, 4,400 ft.; the limits of forest
trees 9,000 ft.; highest limits of vegetation 11 000 ft.; summit of the
SpA 17,600 fi.” The observed temperature of the boiling point he
states at 180° F. on the summit, and a m that deduces the last figures

to see how Prof. Wood deduces his figures from the observations he gives.
A boiling point of 180° F. represents a barometric pressure of 15°26
inches, which in that region, in the month of August, would probably
represent an altitude of 18,350 feet or more. On Mt. Shasta, which is
300 miles farther south, the forest vegetatiow barely extends up 9,000 ft.,
the alleged height on Mt. Hood, where the alpine species are probably
identical-or similar.

It is noticeable how these accounts differ in other important particu-
lars. One finds the summit a mere “pinnacle” only large enough to
stand upon—another speaks of it as half a mile long. All agree that there
is a crater, but one party finds it 3,000 ft. below the summit; we in
from the description of another that it is at the summit, or at least that a
part of its rim forms the summit; one party descended into it a short
distance, but finds a precipice fifty or sixty feet high; another speaks of
a precipice of a mile vertical. The last observers find the crater nearly
filled with snow, while but a few months ago the papers contained ac-
counts of the mountain in active eruption. From all these we see we
are still in doubt as to the actual height and condition of the peak; but
since these ascents demonstrate that the summit is easily accessible, we
hope soon to have more satisfactory observations. W. H. B.

7. Alleged discovery of an ancient human skull in California.—Ac-
counts have recently been going the rounds of the press of the discovery

and investigated the matter as far as ossible, but owing to
the presence of water and the stoppage of work in the shaft, the exam-

ik materials on the western slope of the Sierra Nevada
began in the Pliocene age, and that it continued into the Post-pliocene,
and possibly to comparatively modern times. The alleged position of
the skull is a lower one than any in which the remains of the mastodon
es been found, and therefore the question of its authenticity be-
comes a very Important one; and when the more complete examinatio
has been made, we will lay the results before the readers of the Journal.

One of the larger bones is somewhat broken ; otherwise they appear to

At Batavia I have recently found another outcrop of the Marcellus

out much easier and better than at Avon. This outcrop will, I think,
furnish some fossils not heretofore found in this limestone.
