The diameters of the shaft are somewhat larger than in the FH. foulkei
given by Leidy,
The caudal vertebra is of large size and peculiar form. The centram is
considerably wider than deep, and considerably longer than wide. The
posterior chevron articulations are small, and each is connected with each
anterior by a strong rounded angulation. Between the latter the space is
wide and slightly concave in transverse section, least so medially. _ A
marked peculiarity is seen in the strong longitudinal ridge which divides
the lateral surface of the vertebra into two nearly equal faces. The
neural arch is elongate, the neural canal small: in section a short vertical
ellipse. The articular face of the zygapophyses makes an angle of about
thirty-five degrees to the perpendicular. The crest of the arch rises a
half inch behind these into the very stout basis of the neural spine, the
. greater part of which, with the posterior zygapophyses, is broken off.
The inclination of the base is about 65° to the vertical diameter of the
bone, The articular faces are both slightly concave, as are the lateral
faces which are separated by the lateral ridge.

There is a slight rugose protuberance in the position of the diapophysis.
The peculiarities of this vertebra indicate most strikingly the generic
distinctness of this great reptile from the Hadrosaurus. It is true it
presents some similarity in form to the terminal caudals of that genus
and if it could be referred to that portion of the series, would indicate
merely another and larger species of Hadrosaurus. It differs inform from
these vertebrae, in its depressed instead of compressed form, and its
lateral angulation. That it belongs to a more anterior position in the
tail is evident from the very large size of the basis of the neural spine,
and general greater development of the neural arch and zygapophyses,
and the trace of diapophyses. Further, it is over four times the size of
the terminal caudals of H. foulkei, while the remaining elements do not
indicate any such extraordinary dimensions. A position a little behind
the middle of the series would relate well to the other proportions.
This is another of those remarkable forms which the reptilian type
developed in past ages. That it was herbivorous, and relied less on its
tail for support than Hadrosaurus, appears probable. Large caprolites
of the character of those of herbivorous animals accompanied the bones.
They resemble somewhat those of the hog ; one has a diameter of 3.5 inches
one way, and 2 inches the other; extremity broad, obtuse. The pro-
prietor of the pit told the writer that he had more than once seen large
‘*hoofs’? ‘‘and wide toe-joints’ taken out during the excavation.
This species is different from the Ornithotarsus immanis, Cope, and
belongs to a different genus. The shaft of the tibia in the latter is filled
with cancellous tissue ; in the present.animal it is entirely hollow.

HADROSAURUS TRIPOS, Cope.
Ata point about ten miles distant from the marl pit in which the
Hypsibema was found, Prof. Kerr discovered a caudal vertebra of a
colossal reptile, whose affinities are evidently near to the Hadrosaurus
foulkei.
This vertebra is one of the distal, as evidenced by the entire absence
of any trace of diapophysis, and its subquadrate longitudinal section, as
well as by the small size of the neural arch and spine. At first sight it
would appear to occupy a position between the thirtieth and thirty-sixth
of the series; the former in H. foulkei has, however, rudiments of a
diapopbysis. Both its articular faces are distinctly biconcave. The large

size of the chevron articular face is as in the thirtieth, and the concavity
of its lateral faces as in the twenty-sixth; in the thirty-sixth the sides
are entirely plane. The round form of the neural canal, as well as lack
of diapophysis, are points of resemblance to the thirty-sixth, but it is
more than twice as long as that vertebra in the H. foulkei. In the thirtieth
the neural canal is somewhat depressed and becomes more so as we
advance towards the proximal part of the series. The small antero-pos-
terior extent of the neural arch is much as in the thirtieth in H. foulkei,
but the basis of the neural spine, which is broken off in this, as well as
the odd species, is much more slight. It isso very thin and weak as to
indicate either comparatively a slight development of the spine, or a
very posterior position in the series. A weak lateral ridge marks the side
of the centrum, which is below the middle line. It holds the same position
in the thirty-sixth in H. foulkei, but is above the middle in the thirtieth
and those anterior.

This specimen was procured from the marl pit of W. J. Thompson,

A second and much smaller vertebra from the pit that furnished the
remains of Hypsibema crassicauda, belonged to a third individual, and
possibly to this species. Its proportions would point to a position near
the end of the tail, and its form is less elongate and compressed than
those in that position in H. foulkei. Its neural arch is not codssified. The
extremities are slightly concave, the general form subquadrate.

The first named vertebra pertained to an immense species, perhaps
double the Hadrosaurus foulkei, in weight and bulk, should the general
proportions of the two have been at all similar. In that case the length
of the femur would be sixty-two and a quarter inches.
It will remain for future discovery to determine whether the species is
the same as the Ornithotarsus immanis.

Obiiuary Notice of
Str Jonn FREDERICK WILLIAM HERscHEL, BaRtT.,
By Mr. Henry W. Frievp, or Lonpon.
Read before the American Philosophical Society, December 1, 187i.
It is the painful duty of our Society to record the loss we have sus-
tained in our membership, and indeed we may well say, the loss to the
world in general, by the decease of the illustrious Sir John F. W. Her-
schel, Bart.
His father, Sir William Herschel, came from Hanover to England, in
1759, as one of the Hanoverian Guards’ Band; and was for some time the
subject of disappointment and privation. He however became instructor
to a regimental band, stationed in the North, and fortunately obtained an
organist’s appointment in Yorkshire, and subsequently at Bath. Here
it was that his taste for astronomy became developed, and from whence
his first papers, ‘Observations of the Periodical Star Mira Ceti ” issued.
They were read before the Royal Society, in London, on the 10th May,
1780. :
In 1781, the results of his studies and speculations led to his great dis-
covery of Uranus (specially interesting from its leading to the discovery
of the remote planet Neptune) which placed him most prominent in Sci-
entific rank, which standing he retained until his death in 1822, being then
in his 84th year.
Mr. Herschel, our lamented member, (unlike his father who raised him-
self from the humble rank of a regimental musician) after being edu-
cated privately by a Mr. Rogers, at an early age entered St. John’s College,
Cambridge, where by his great success and taste for science he graduated
B. A. in 1813. He came outin the Mathematical Tripos, Senior Wrangler;
an honor which was further enhanced by his attainment of the Firs
Smith’s Prize. That his year was what is called, in Cambridge, ‘‘a good
year,”’ is evident from the names of the distinguished men of whom he
took precedence, such as the following :—Peacock, Dean of Ely ; Fallows,
late Astronomer Royal at the Cape; Romilly, late Registrar of the Uni-
versity ; Amos, Mill, and other men of note, whose names adorn the Det
partments of Science, Theology and Literature. It may be worth while
to note the feeling which subsisted among his fellow collegians ; Charles
Babbage, the mathematician (lately deceased) who coveted the honor of
of Senior Wranglership, but knowing the powers of his antagonist, Her-
schel, declined to appear in the Mathematical Tripos, choosing rather to
be at the Head of the Poll.
On the 27 May, 1813, he was elected Fellow of the Royal Society, and
became one of its most active members, receiving in 1821 the Copley
medal.
At his father’s death he pursued that branch of science calied ‘‘ Observ-
ing A stronomy,’’ and about this time he conceived tie desirability of form-
ing a Special Society, and was most active in its foundation, the present
‘‘Royal Astronomical Society.”’

Field.] 21 8 , [Dee. 1,
In 1831, King William, as a tribute to his great scientific services con-
ferred on him the honor of knighthood.
Sir John Herschel’s researches on the positions of Nebule and clusters
of stars, took up many years of his life. Several of the results he pub-
lished in conjunction with Mr. (after Sir James) South, for which a re-
ward of a gold medal was presented to both Astronomers. Were it not
for the sincere love of science, the toil of these proceedings from mid-
night to sunrise would not have taken place; for no one can tell the strain
on the constitution, the severity of which is gleaned from his observations
while discussing the double stars. He remarked :
“Should I be fortunate enough to bring this work to a conclusion, I
shall then joyfully yield up a subject on which I have bestowed a large
portion of my time, and expended much of my health and strength, to
others who will, hereafter, by the aid of those masterpieces of workman-
ship, which modern art places at their disposal, pursue with comparative
ease and convenience an inquiry which has presented to myself difficulties
such as at one period had almost compelled me to abandon it, in despair.’’
Tn 1838, Sir John Herschel was awarded the Royal Medal of the Royal
Society, for his paper ‘‘ On the Investigation of the Orbits of Revolving
Double Stars.”” The Duke of Sussex, President, gave the following
graphic account of his labors :
“Sir John Herschel has devoted himself, as you well know, for many
years at least, as much from filial piety as from inclination, to the exam-
ination of those remote regions of the universe into which his illustrious
father first penetrated, and which he has transmitted to his son as a he-
reditary possession, with which the name of Herschel must be associated
for allages. He has subjected the whole sphere of the heavens within
his observation, to a repeated and systematic scrutiny. He has determ-
ined the position and described the character of the most remarkable of
the Nebulaz. He has observed and registered many thousand distances
and angles of position of double stars, and has shown, from the compari-
son of his own with other observations, that many of them form systems,
whose variations of position are subject to invariable laws. He has suc-
ceeded by a happy combination of graphical construction with numerical
calculations, in determining the relative elements of the orbits which
some of them describe round each other, and in forming tables of their
motions ; and he has thus demonstrated that the laws of gravitation,
which are exhibited as it were, in miniature in our own planetary system,
prevail also in the most distant regions of space ; a memorable conclusion
justly entitled by the generality of its character to be considered as form-
ing an epoch in the history of Astronomy, and presenting one of the
most magnificent examples of the simplicity and universality of those
fundamental laws of nature, by which their great Author has shown that
he is the same to-day and for ever, here and everywhere.
‘That he was not a mere meditative Philosopher, but one of laborious
research and of a practical turn, appears from the imposing catalogue of
his written works, a few of which I may be pardoned for enumerating: 13
1871.] 219 [ Field.
papers on Optics; 28 on Astronomy ; 10, Pure Mathematics, on Geol-
ogy ; on Photography ; on Chemistry ; on Natural Philosophy.
“The Encyclopedia Britannica boasts of excellent articles on Light and
Sound, and Meteorology, now published separately.”’
A Manual of Scientific Enquiry, published by the Admiralty.
The Philosophical Transactions contain many of his valuable re-
searches, especially those read before the Royal Society, 19 Nov., 1863,
which will ever show his energy and perseverance in spite of the infirmi-
ties of his advancing age. In fact, turn where you may, light, emanating
from Sir John, seems to cast its beams on almost every department of
Science.
It may not be out of place to give an extract from his work ‘‘ Outlines
of Astronomy,’ a book which fills the student’s mind with enraptured
interest in the marvels which he reveals in plain and perspicuous lan-
guage ; for example:
“There is no Science which, more than Astronomy, draws more largely
on that intellectual liberality which is ready to adopt whatever is demon-
strated, or concede whatever is rendered highly probable, however new
and uncommon the points of view may be, in which objects the most fa-
miliar may thereby become placed. Almost all the conclusions stand in
open and striking contradiction with those of superficial and vulgar ob-
servation, and with what appears to every one until he has understood
and weighed the proofs to the contrary, the most positive evidence of his
senses. Thus, the earth on which he stands, and which has served for
ages as the unshaken foundation of the firmest structures, either of art
or nature, is divested by the Astronomer, of its attribute of fixity ; and
conceived by him as turning swiftly on its centre, and at the same time
moying onwards through space with great rapidity. The sun and the moon,
which appear, to untaught eyes, round bodies of no very considerable size,
become enlarged on his imagination into vast globes : the one approach-
ing in magnitude to the earth itself; the other immensely surpassing it.
The planets which appear only as stars, somewhat brighter than the rest,
are to him spacious, elaborate and habitable worlds; several of them
much greater and far more curiously furnished than the earth he inhabits,
as there are also others less so; and the stars themselves, properly so-
called, which to ordinary apprehension present only lucid sparks or
brilliant atoms, are to him suns of various and transcendent glory, ef-
fulgent centres of life and light to myriads of unseen worlds. So that,
when after dilating his thoughts to comprehend the grandeur of those
ideas his calculations have called up, and exhausting his imagination and
the powers of his language to devise similes and metaphors illustrative of
the immensity of the scale on which his universe is constructed, he
shrinks back to his native sphere; he finds it, in comparison, a mere
point ; so lost, even in the minute system to which it belongs, as to be
invisible and unsuspected from some of its principal and remote members.”’
Without fatiguing the Society, I think the following paragraph on the
study of Natural Philosophy, will be its own apology for insertion.
Field. ] 220 [Dec, 1,
** Among the most remarkable of the celestial objects, are the revolving
double stars, or stars which to the naked eye or to the inferior telescope
appear single, but if examined with high magnifying powers are found
to consist of two individuals placed almost close together, and which when
carefully watched are (many of them) found to revolve in regular elliptic
orbits about each other ; and, so far as we have as yet been able to ascer-
tain, to obey the same laws which regulate the planetary movements. There
is nothing calculated to give a greater idea of the scale on which the siderial
heavens are constructed than these beautiful systems. When we see such
magnificent bodies united in pairs, undoubtedly by the same bond of
mutual gravitation which holds together our own system, and sweeping
over their enormous orbits in periods comprehending many centuries, we
admit at once that they must be accomplishing ends in creation which
will remain for ever unknown to man; and that we have here attained
a point in Science where the human intellect is compelled to acknowledge
its weakness, and to feel that no conception the wildest imagination can
form, will bear the least comparison with the intrinsic greatness of the
subject.” j
England was not the only spot from which he made his observations.
He found it desirable to carry on his investigations at the Cape of Good
Hope, and for this far off scene of inquiry he embarked with his family
at Portsmouth, 13 Nov., 1833. The course he prescribed to himself seems
to have been to restrict his labors almost, if not entirely, to Stellar As-
tronomy. Still he didnot omit to make many careful observations of the
Nebula of Orion, of the Milky Way and of other heavenly phenomena ;
making accurate drawings, which he subsequently published.
In May, 1837, an extraordinary spot appeared on the sun’s disc, the
marvel of which was much increased when Sir John published his caleu-
lation that the ‘crater of this supposed voleano was sufficiently large to
allow the globe of the earth to pass in leaving all around a margin of
1000 miles.
On his return to England, in 1838, after, as he states, enjoying much
happiness, together with the pleasures of good society, his grateful coun-
try bestowed upon him the dignity of a Baronetcy.
At this time, Photography beginning to attract much public attention,
Sir John turned his thoughts to this beautiful art, directing his inquiries
chiefly to that point so important to Photographers, the chemical action
of solar rays.
Of the value attached to Sir John’s scientific attainments we have
abundant evidence in the instances in which he was called upon to occupy
the place of advisor and councilor. As member of the Board of Visitors
of the ‘‘ Royal Observatory,’’? when he was appointed to receive the annual
report of its working and efficiency, a member of the ‘‘ Standard Commis-
sion”? on the question of the introduction of the ‘‘Metric System of
Weights and Measures ;”’ for many years as one of the leading members
of the Council of the Royal Society.
On the retirement of Davies Gilbert, this venerable Society of savans

nearly succeeded in compromising its title, by almost electing the ple-
beian philosopher to the dignity of President, in preference to the Royal
patron of science and literature, the Duke of Sussex. So keen was the
contest that the subject of our memoir lost it only by 8 votes in a meet-
ting of 240 members. He was President of the Astronomical Society
three times. In 1845, he presided at the British Association for the Ad-
vancement of Science at Cambridge. Many learned European societies,
beside those of his own country, rejoiced to inscribe his name on their
rolls; but to none of them will our American Philosophical Society yield
in its admiration, of this great citizen of the tepublic of Literature and
Science, as evinced by the bestowal upon him of their diploma of member-
ship. In 1842, he was elected Lord Rector of Marischal College, Aber-
deen. :
The last of his public official positions, previously to his retirement into
the quietude of a country life at Collingwood, in Kent, was that of Master
of the Mint, to which he was appointed December 16, 1850, and which he
retained until Professor Graham’s appointment, Apri 283. 18pdec im
this office Sir John was a worthy successor of the great Sir Isaac Newton,
who filled that office in the reign of William III.
In subsequent times, the Mastership acquired a political character and
was conferred generally on members of the Cabinet, which continued
until what is known familiarly amongst Mint employés, the Revolution
of ’51, by which the old system of. charters, indentures and contracts for
the meltings and coinages, being considered antiquated, it was desired
by the higher powers to abolish. Naturally, this move caused much
alarm and dissatisfaction ; the distastefulness of which was, however,
greatly modified by the gentle and considerate manner in which Sir John
exercised the authority entrusted to him.
The labor and anxiety inseparable from a reconstruction of so import-
ant an establishment, much impaired the health of the subject of this
memoir. Still his mental vigor did not succumb to bodily infirmity, as
daily he was at his post about 11 o’clock, rarely leaving till 5 or 6 p. m.,
when he might be seen walking out with his portfolio under his arm, filled
with papers to consider and revise, as an evening amusement.
Among the many alterations made by Sir John, he framed and calcu-
lated tables for standarding the various qualities of gold and silver, which
superseded those said to have been Sir Isaac Newton’s.
He sanctioned the abandonment of ‘ Trial Plates’’ (designated by Sir
John “ Fiducial Pieces ”’) which had been prepared from time to time
and used for centuries, and presumed to be mathematically of the due
proportions of the pure noble metal, but not really so. In lieu of this
practice Sir John directed the Queen’s Assay Master to use his best en-
deavors to obviate the evil, so that no officer of a foreign mint should be
able to question the conventional purity of our British coin as being other
than for gold 916.6, and for silver 925.
In giving effect to the Master's wishes, the Queen’s Assay “Master
worked out the important correction by preparing and introducing chem-
222 [Dee. 1,
Field.]
ically pure gold and silver, in place of the standard trial plates. The
following extract from Sir John’s correspondence may be appropriately
introduced here.
“The almost mathematical coincidence of the result of the Pyx (about
30 millions) with the legal standard, is the best proof which can be ad-
duced of the admirable system of working the assays.”’
As illustrative of the unfailing kindness of this great man towards
friends, as well as towards those, who had had the happiness to serve
under him, the writer may be pardoned for introducing some of his last
utterances contained in a letter, penned only five weeks before his depart-
ure to those realms of Light and Truth, amidst the wonders of which,
while in the flesh, he loved to live.
“T am suffering under an attack of Bronchitis, which has lasted me all
the winter, so excessively severe that I can hardly hold the pen, which
must excuse the brevity of this, and being now in my 80th year, I can
hope for no relief. I shall retain, however, to the last, a pleasing recol-
lection of aid and support I received from you during the period of my
administration of the Mint, and I know you will believe me ever, my
dear sir, yours, most truly, ;

In his domestic circle, he could unbend to the capacity of the young,
in whose amusements he joined with spirit, and considering his advanced
years, with wonderful energy. It may be instanced that, only a few years
back, the great astronomer condescended to enter cordially into the
children’s Christmas gambols, and played in the most animated manner
the part of Sir George with the Dragon; habiting himself in a coat of
mail, extemporized from various culinary articles. His impromptu dia-
logue with his son as ‘‘the Dragon,’’ was said by the elders to be ab-
surdly clever. ‘‘The Herschels do everything well’? was a common way
of speaking of the philosopher and his family ; so here the Dragon was
so life-like, though made only of brown paper with a scarlet cloth tongue,
and the knight looked so doughty, that the tableau nearly sent one of the
children into convulsions.
Sir John F. W. Herschel, Bart., K. H., D.C. L., &c., was born at
Slough, near Windsor, 7 March, 1792. He married, in 1829, Margaret
Brodie, daughter to the Rev. Dr. Alexander Stewart, by whom he had a
family of three sons and nine daughters. One is married to General, the
Hon. Alexander Gordon, uncle of the present Lord Aberdeen, and now
heir presumptive to that title. His youngest son is an officer in the Royal
Bengal Engineers. He is succeeded in the title by his son Mr. William
James Herschel, of the Bengal Civil Service, who was born in 1833 and
married in 1864, Anne Emma Haldane Hardcastle, daughter of the late
Mr. Alfred Hardcastle, of Hatcham, Surrey.
Sir John died at his seat, Collingwood, Hawkhurst, Kent, on Thurs-
day, the 11th May, 1871, at 10 o’clock a. M., being in his 80th year. He
was buried in Westminster Abbey, on Tuesday, the 19th May. His re-

mains were followed by the Presidents and many members of the various
learned societies of England, also by the chief men of science in London.
The well-known Dean Stanley officiated on the mournful occasion, and
on the following Sunday delivered in the Abbey one of his beautiful char-
acteristic sermons, which may be found én etenso, in the July number of
“Good Words,” p. 453 (a work to which he occasionally contributed
some popular papers on the wonders of the Universe). The Dean took
his text from the 14th and 15th verses of the 1st chapter of Genesis.
“ And God said let there be lights in the firmament of the Heaven to
divide the day from the night; and det them be for signs and for seasons
and for days and years; and let them be for lights in the firmament of
the heaven to give light upon the earth; and it was so.”
Glancing at the private sentiments of Sir John, in these days, when there
appears to be an increasing antagonism between science and revelation,
it is refreshing to remember how frequently in his writings, and in con-
versation with some of his friends, strong indications are observable, that
the lofty mind of him who was a master in the science of the starry
heavens could penetrate into higher regions still, and forget the proud
achievements of intellect and science, in the humility of the adoring
Christian; a humility which also manifested itself towards man in count-
less acts of generous sympathy and consideration. Of him truly it may
be said in the language of a poetical tribute to his memory, which has
recently appeared in a periodical of the day (‘‘ Good Words’’).
‘+ Seience and learning led his mind, in reverent awe above ;
To him the voices of the stars proclaim’d their Maker’s love.”
In the above sketch of the scientific, official and personal character of
the departed, it will be sufficiently apparent that with numberless other as-
sociations of the learned and scientific, in the decease of Sir John Herschel,
our Society has to deplore the loss of a member whose name adorned the

In July last, a letter was received at the Smithsonian Institute, from
Mr. Jacob W, Moffit, of Chillicothe, Peoria county, Illinois, enclosing the
photograph of a medal or coin, with the following particulars in relation
to it:
“In August 1870, I took a contract of sinking a tubular well for Mr.
Peter Cline, in this county. I had two men employed to assist in the
labor, who are cognizant of all the facts connected with the finding of the
coin.
“The following are the several strata through which we passed. We
used a common ground auger, three inch bore :
“Soil, 3 feet. Yellow clay, 10 ; blue clay, 44 ; clay, sand, and gravel 4 ;
purple clay, 19 ; brown “‘hard pan,” 10; green clay, 8} ; vegetable mould,
2; yellow clay, 24; yellow hard pan, 2; mixed clay, 205.
“Here we brought up the coin,on the auger, from a depth of one hundred
and twenty-five feet.
“Tt has been examined by gentlemen in Chicago and St. Louis, without
any result in explaining the mystery of its origin or date. It is my desire
that a further investigation be made. I can, if necessary, send affidavits
of myself and other parties as to the truth of these statements.”
[Signed ] Jacos W. Morrit.
It may here be added, that the place is in a great prairie, near the
centre of the State, and near the Illinois river ; about 80 miles east of the
Mississippi river.
Professor Henry having repeatedly referred rare coins to me, took the
same course on this occasion, giving leave to communicate the facts to
this society, if it was thought proper.
An examination of the piece itself was necessary ; and in reply to my
request the owner forwarded the same, with further details, to wit :
“Tn answer to your questions I must say, that very few wells or shafts
in this region have attained a depth of more than 50 or 75 feet, except in
the valleys, where occasiondlly we find a well, through sand and gravel
drift, at the depth of 100 feet.
“The only token of civilization discovered at a similar depth, in this
State, was taken from a shaft in Whiteside county, about 20 years ago.
The workmen at the depth of 120 feet discovered a large copper ring or
ferrule, similar to those used on ship spars at the present time, They also
found something fashioned like a boat-hook.
«There are numerous instances of relics found at lesser depths. A spear-
shaped hatchet, made of iron, was found imbedded in clay at 40 feet ;
and stone pipes and pottery have been unearthed at depth varying from
10 to 50 feet in many localities.
“No rational estimate has ever been made of the rate of annual earthy
deposit. Our prairie land seems to have been built up by a deposit from

waters whose current set in from the N. W., changing its course only
when in contact with some (then) eminence now far below the surface.
The soil is seldom over three feet in thickness, usually underlaid by a yel-
low hard-pan of two to three feet. Wood is quite common at all depths
at which wells have been sunk in blue clay.
“Nothing has been found in any of the Western mounds (as far as I
am informed) bearing any resemblance in form or character to this coin.
‘‘On taking the coin from the auger, I washed the clay from it with
water. It then presented no appearance of corrosion, bearing a dull red
hue, such as is common to old copper. However, after a few minutes,
exposure to the air, it began to blacken, and in a short time was en-
crusted with a dark green, gummy coat, which I allowed to harden, and
then removed by friction.’’ :
Thus far from Mr. Moiiit. I learn from another source, that Chillicothe
is built upon an alluvium of the Illinois river, very sandy, loose, and easily
washed away. The river thereabouts is widened into a lake, about one
mile and a quarter wide, and twelve miles long. The French pioneers
went through that region, about the close of the seventeenth century.
Whether the ground on which Chillicothe stands, has been made by the
river, to the depth of 125 feet, since the entrance of the whites, is a point
on which the residents there, with or without geological instruction, can-
not venture an opinion.
As to the facts as above stated, there isevery reason to rely upon their
accuracy. Ihave to add some remarks on the physical and artistical
traits of the coin itself. :
‘ Properly speaking, it is not a coén or medal, since the marks upon it
have not been produced by striking, but by engraving or etching; and
they are sunken, or intaglio. It is of copper in good condition, in shape
polygonal approaching to circular, about one and an eighth inch in
diameter ; somewhat pitted by corrosions, and with very rude figures and
inscriptions ou both sides. The central image on one side is that of a
man, or a child; on the other are two animals, one of them like a wild
cat, with conspicuous ears. The legends are plain enough, to any one
who can read them; but being somewhere between Arabic and Phono-
graphic, without being either, they are sufficiently puzzling. Happily
we have members whose knowledge of paleography may throw some
light. For myself, I have seen nothing like it.
As to the other artistic characters, the metal proves, by a delicate gauge,
to be very uniform in thiékness ; more so than could be attained by the
beating out of a hammer in savage hands. I therefore feel sure it has
passed through a rolling-mill ; and if the ancient Indians had such a con-
trivance, it must have been pre-historic.
There are other tokens of the machine shop. Any one can see that the
piece has been shaped, not with much symmetry, with shears or chisel ;
and the sharp edge taken down with a file. Coins or medals were not
thus finished in ancient times, but they were in the middle ages, andin

Spanish America down to about 150 years past. (Tapping the edge with
a hammer, was also in use):
If the figures and characters were made with a tool, it must have been
a very rude one, since a ‘‘flat-nosed ” graver would have left a smooth
trough, while here it is rough and granular. This would suggest the
greater likelihood of etching, were it not inconceivable that so advanced
an art should have been practiced long ago on the Western prairies. The
mineral acids, used for such work, were nowhere known until about the
fourteenth century ; and in Illinois, while we might suppose agua ardiente,
we cannot concede aqua fortis, longer ago than one century. On the
whole, it has been worked out with a very crude instrument.
As to the condition of the piece, and the discolorations; it is well known
that copper, exposed to the air, acquires a superficial sub-oxide or dioxide,
which protects it from further destruction. Very many ancient copper
coins have been turned up by the spade or plough, which with a little
cleaning up, look as if just out of the mint. I herewith show a specimen
of Tetricus, a Roman usurper of the purple, in France, about A. D. 270;
entirely free from corrosion. I also show a more interesting piece, which
with many others, was ploughed up in the southern part of England,
about 30 years ago. They were all so encrusted as to be illegible, and
the owner gave me a choice at haphazard. On removing the coat of mail,
and leaving only the mixture of brown and black oxides, it turned out to
be a coin of Carausius, who established himself as a Roman Emperor in
Britain, A. D., 287; as long before William the Conqueror, as William
was before Victoria. This piece is rare and in perfect order, and forms a
part of the Mint collection. ;
Some ancient coins, especially those with a slight alloy of tin or cala-
mine, making them bronze or brass, are beautifully coated and protected
with the green carbonate, the same as that which formed on the Illinois
piece before cleaning. I herewith show one of these patinated pieces, a
coin of Augustus, also from the Mint Cabinet. They may have been in
favorable hiding-places, such as cinerary urns, or columbaria.
All things considered, I cannot regard this Illinois piece as ancient, nor
old, (observing the usual distinction); nor yet recent; because the ‘tooth
of time’’ is plainly visible.
What the piece was made for, is a part of the inquiry. Not for current
money, bevause it would take a long time to make a handful ; more likely
a work of amusement, possibly to exercise the antiquarians. But how
it got into such a deep place, supposing it a bona fide discovery which I
eannot call in question, is a very perplexing point, and I gladly hand over
the explanation to any one willing to undertake it. Certainly it seems,
in connection with the finding of the copper ring, and other articles of
iron and wood, at considerable depths, to form an item in the study of
the formation of the superficial strata in that interesting section of our
country. :
Since the foregoing was written, I am favored with the suggestions (in
writing) of Professor Lesley. He suspects that if anything, it is an
astrological amulet. There are upon it the signs of Pisces and Leo. The

figures, on the obverse and reverse faces correspond in the attitude of the
left arm raised and flourishing a whip, or thunderbolt. He reads the date
1072, and says that no geologist can accept the statement that a piece
of that age could be lying naturally at a depth of 125 feet, under an
Illinois prairie. The piece was placed there as a practical joke, though
not by the present owner; and is a modern fabrication; perhaps of the
sixteenth century; possibly of Hispano-American, or French-American
origin. It may have some connection with the journeys of the early
French priests or their voyageurs.
I would only add, that those views are forcible, but yet they take
imposture for granted, and in so doing, leave us in this dilemma; that a
curious piece was made many years ago, and held for the purpose of trick,
until a deep hole should be made, long afterwards, in which to bury it,
and complete the deception. It is also very hard to believe, that an
intelligent and experienced operator in this line would allow himself to be
sported with by workmen, and take so much pains, far and near, to
ascertain what kind of article he had found.
Mr. Lesley explained :
He considered the integrity, experience and vigilance of the well sinker
no guarantee against the surreptitious insertion of the coin. It is impos-
sible to prevent a practical joke of that sort when the jester is resolved to
have it so. Experience furnishes a thousand proofs of this in our exten-
sive oil regions, where all kinds of rubbish have been brought to the sur-
face from considerable depths ; nails, anthracite coal, California nuggets,
‘‘butter of antimony,’’ Lake Superior Red hematite iron ore, &e.
It looks as if there is a good deal of this sort of thing going on in the
west. The copper-ring and boat-hook ‘taken from a shaft at Whitside;
at a depth of 120 feet,’ ‘‘the iron spear-shaped hatchet embedded in clay
at 40 feet’? mentioned in the paper, are subjects for the same incredulity.
The only possible explanation, excluding an imputation of fraud, in the
latter case, would presuppose the recent filling up of a hole in the river
bed with clay, through which a piece of iron might slowly settle down.
The discovery of a circular stone fire-place, with embers, by Mr.
Latrobe’s party of engineers in a gravel cut for the road bed of the Balti-
more and Ohio R. R., many years ago, at a depth of 50 or 60 feet beneath
the surface, is a circumstance belonging to quite a different category.
In the present case we have an evident imitation of Mediterranean coins.
But the central figures are unmistakably Red Indian in their character.
It is either unique of its kind, or one of a very small class. The proba-
bilities against a borehole striking such an object are simply infinity to
one. The improbabilities of the coin being at or near the surface, and
being worked out from the wall of the hole by the friction of the rods, is
equally great. There is too much method in the arrangement of the
elements of the legend to doubt that the maker had a definite idea to
express. A compound oval symbol occupies the right edge on each face,
and may have a phallic significance. But the two human figures on one
228
face seem rather to be in conflict than in conjunction. The head dress
may represent hair, or may represent the Indian warrior’s feather crest.
Professor Trego remarked that he had seen the once famous grave
mound relic and the man ‘‘ who discovered’’ and possessed it, and believed
it to be fraudulent. He had no faith in such discoveries in the west.

more intelligence. §
As examples of intelligent selection, the modified organisms of the va-
rieties of bees and ants must be regarded as striking cases. Had all in
the hive or hill been modified alike, all soldiers, neuters, etc., the origin of
the structures might have been thought to be compulsory ; but varied
and adapted as the different forms are to the wants.of a community, the
influence of intelligence is too obvious to be denied. The structural re-
sults are obtained in this case by a shorter road than by inheritance.
The selection of food offers an opportunity for the exercise of intelli-
gence, and the adoption of means for obtaining it, still greater ones. It
is here that intelligent selection proves its supremacy as a guide of use,
and consequeiitly of structure, to all the other agencies here proposed.
The preference for vegetable or for animal food determined by the choice
of individual animals among the omnivores, which were, no doubt, ac-
cording to the paleontological record the predecessors of our herbivores,
and perhaps of carnivores also, must have determined their course of life
and thus all their parts, into those totally distinct directions. The choice
of food under ground, on the ground, or in the trees would necessarily
direct the uses of organs in the appropriate directions respectively.
In the selection of means of defence a minor range of choice is pre-
sented. The choice must be limited to the highest capabilities of the ani-
mal, since in defence, these will, as a general thing, be put feith. This
will, however, not be necessarily the case, but will depend in some meas-
ure on the intelligence. of the animal, as we readily observe in the case
of domesticated species,
In the case of the rattlesnake, already cited, the habit of rapid vibra-

Cope.]
tion of the tail, appears to me to be the result of choice, and not of com-
pulsion. For the cobra, of India, for the same purpose, expands the an-
terior ribs, forming a hood, which is a very different habit. Here are two
alternatives, from which choice might be made; and violent hissing is a
third, which the species of the colubrine genus Pityophis, haveadopted to
some purpose. As to the benefit of the rattle, it no doubt protects the
animal from all foes other than man; but is rather a disadvantage as re-
gards the latter, being by a beautiful turn of events a protection to the
higher animal.
On the principal of natural selection it might be supposed that the
harmless snakes which imitate the Crotalus for the sake of defence were _
preserved ; but if the above explanation of the origin of the habit in the
latter be true, the second explanation is not valid.
"The power of metachrosis, or of changing the color at will, by the ex-
pansion under nerve influence of special pigment cells, exists in most
Reptilia, Batrachia and fishes. It is then easy to believe that free choice
should, under certain circumstances, so habitually avoid one or another
color as to result finally in a loss of the power to produce it.
Thus, it appears to be a fact, that not only are species of fishes which
dwell in the mud, of darker hues than those that inhabit clear water, but
that individuals of the same species differ in a similar manner in relation
to their habitats, those that live in impure or muddy waters having
darker tints than those of clear streams.
Land animals present equally abundant and remarkable imitations of
the objects or substances on which they live. This is well known in in-
sects and spiders, which look like sticks or leaves, or the flowers on which
they feed. It is seen in reptiles, which in very many cases can voluntarily
assume the hue of leaf, stone or bark, or have constantly the gray color
of their native desert sands.
These cases are largely selective or optional in their origin, for though
metachrosis is also induced by some external stimulus, as an enemy or a
food animal, yet other means of escaping the one and procuring the other,
are generally open.
These facts pave the way for a consideration of the phenomenon of
mimetic analogy which, though well known to naturalists, may be illus-
trated by the following new facts :
On the plains of Kansas, there isa species of Mutilla whose abdomen
and thorax are colored ochraceous or brown-yellow, above. A spider of
the genus Saitéews is equally abundant, and is almost precisely similar in
the color of the upper surfaces, so much so as to deceive any but a most
careful observer. The Mutilia being a well armed insect, and a severe
stinger, there can be no doubt that the Saltiews derives considerable im-
munity from enemies from its resemblance.
On the same plains, the Caudisona confluenta, or prairie rattlesnake
abounds. It is an olive grey, with a series of transverse brown dorsal
spots, and two rows of smaller lateral ones. The head exhibits a num-
1871 ] 261 [Cope.
ber of brown and white bands. The prairie Heterodon, (H. nasicus) pos-
sesses not only the same tints but the same pattern of coloration, and at a
short distance cannot be distinguished from it.
In consequence, as one may justly say, this species is, with the rattle-
snake, the most common serpent of the plains, as it shares, no doubt, in
the protection which the armature of the Caudisona gives its possessor.
This isin accordance with the views of Wallace and Bates.
A curious case occurred to me in four species of fishes, which I took in
a small tributary of the Yadkin River, in Roane County, N. C. Among
several others, there were varieties of the widely distributed species
Chaenobryttus gillti, Hypsilepis analostanus and- Ptychostomus pidiensis,
(each representing a different family), which differ from the typical form
of each in the same manner, viz: in having the back and upper part of
the sides with longitudinal black lines, produced by a line along the mid-
dle of each scale. This peculiarity I have not observed in these species
from any other lecality. Until I had examined them I thought them new
species.
The only other species presenting such marking in the Yadkin River,
is the large perch, the Roccus lineatus. According to the theory of
natural selection a resemblance to this well armed species might be of ad-
vantage to the much weaker species in question ; yet the same species
co-exist in other rivers without presenting the same mimicry.
It is difficult not to urge the importance of the causes already regarded
as efficient in the origination of structure, in the present branch of the
subject also. We are especially disposed to call in use and effort here,
after noticing how much more distinctly change of color is under the con-
trol of the animal, than change of shape. It must, however, be borne in
mind that similar resemblances exist among plants; though, as Prof.
Dyer shows, a large majority of these cases occur in species of different
floral regions. Thus in this case, as in those of structure already cited,
we appeal first to physical laws in the lowest beings, but with the in-
creasing interference of use, effort aud intelligence, as we rise in the
scale. Thus it is that in the Vertebrates generally, the mimetic resem-
blances are found in species of the same region, where only an intelligent
or emotional agency could be illustrated. If among animals as low as
butterflies the influence of intelligence be denied, that of admiration for
the beauty, or fear of the armature, of the predominant species imitated,
would appear to be sufficient to account for the result. Admiration and
fear are possessed by animals of very low organization, and with the in-
stincts of hunger and reproduction, constitute the most intense metaphysi-
cal conditions of which they are capable. But our knowledge of this
branch of the subject is less than it ought to be, for animals possess many
mental attributes for which they get little credit.
It appears to be impossible to account for the highest illustrations of
mimetic analogy in any other way, the supposition of Wallace that such
forms must be spontaneously produced, and then preserved by natural
Cope. ] 26 2 . [Dee. 15;
selection, being no explanation. It has been shown by Bennett that the
chances of such modification arising out of the many possibilities are ex-
ceedingly small.
If the above positions be trae, we have here also the theory of the
development of intelligence and of other metaphysical traits: In accord-
ance with it, each trait appropriates from the material ‘world the means
of perpetuating its exhibitions by constructing its instruments. These
react by furnishing increased means of exercise of these qualities, which
have thus grown to their full expression in man.
CRITIQUE.
1. On the preceding essay.—There will probably be found to be consid-+
erable resemblance and coincidence between the theory of Use and Effort,
and the Lamarckian view of Development. The writer has never read
Lamarck in French, nor seen a statement of his theory in English, except
the very slight notices in the Origin of Species and Chambers’ Encyclo-
peedia, the latter subsequent to the first reading of this paper.
Darwin’s only speculations as to the origin of new structures which are
contained in his ‘‘ Origin of Species”? (Ed., 1860), so far as I can find,
occur in the first and fifth chapters. In the first he says, discussing the
variability of domesticated animals and plants, ‘‘ I think we are driven
to conclude that this greater variability is simply due to our domestic
productions having been raised under conditions of life not so uniform as,
and somewhat different from, those to which the parent species have
been exposed under nature. There is also, I think, some probability in
the view. propounded by Andrew Knight that this variability may be
partly connected with excess of food. * * * But I am strongly in-
clined to suspect that the most frequent cause of variability may be at-
tributed to the male and female reproductive elements having been
affected prior to the act of conception. * * Nothing is more easy than
to tame an animal, and few things more difficult than to get it to breed
freely under confinement, even in the many cases where the male and
female unite,’’ etc. Chapter V. repeats similar propositions but states
that the effect of climate he believes to be small, but rather greater in
plants than animals,
The view as to the impressibility of the reproductive element is taken
up by Mivart, but the subject remains in the chaos of unshaped hy-
potheses.
2. On the Origin of Genera.—The memoir issued by the writer under
the above name was chiefly devoted to the demonstration of the law of
Acceleration and Retardation. A small portion was devoted to geograph-
ical and geological relations. It remains to correct two errors in the
former portion of the book.
(1). It is there stated (p. 5) that the Law of Natural Selection of Dar-
win is as follows: ‘‘ That the will of the animal applied to its body in the
search for means of subsistence and protection from injuries, gradually
produces those features which are evidently adaptive in their nature.
1871.] 26 3 [Cope,
That in addition, a disposition toa general variation, on the part of the
species, has been met by the greater or less adaptation of the results of
such variation to the varying necessities of their respective situations.
That the result of such conflict has been the extinction of those types
that are not adapted to their immediate or changed conditions and the
preservation of those that are.”
It is unnecessary to state that the first sentence of the above does not
express the theory of Darwin in any part or particular, while the two fol-
lowing do.
Further, it is stated (same page), ‘« What we propose is, that of [gen-
eric characters] comparatively very few, in the whole range of animals
and plants, are adaptations to external needs of forces, and that of specific
characters a large proportion is of the ‘same kind. How, then, could
they owe their existence to a process regulated by adaptation?’ Below,
it is again said, ‘that while Natural Selection acts by the ‘preservation
of the fittest,’ Acceleration and Retardation act without any reference to
fitness at all; that instead of being controlled by fitness it is the controller
of fitness.”’
Thus, from the existence of large numbers of non-adaptive characters I
was induced to believe that an antagonism existed between the two laws.
The present essay shews this to have been an error, and that by recon-
ciling them, they become coérdinate factors in producing the result.
Thus ‘Acceleration and Retardation” is the “controller of fitness,’’
because all adaptive structures are produced in accordance with it, and
in no other way. The law of Intelligent Selection also prescribing fitness,
removes it from the domain of physical or material necessity implied by
Darwin’s law of “Survival of the fittest.” Adaptation therefore is
the guide of change, though not the mechanically produced adaptation
implied by natural selection. The disturbance of: the balance of forces
produced under its influence, leaves growth force to create primarily, the
great number of unadaptive characters, which are simply wnjinished adap-
tive ones, and secondarily, others occasioned by excess or loss of force
in different directions. .
The reconciliation of these laws and their complementary relations
were perceived before the essay was completed, see in the recapitulation.

Catalogue of the PytHonomorrHa found in the Cretaceous Strata of
Kansas.

(Read before the American Philosophical Soctety, December 17th, 1871.)
The following brief review is prepared in consequence of the acquisition
by the author of a considerable accession of material from the chalk cf
Western Kansas. Attention is confined to one order of Reptiles at pres-
ent, owing to its predominant importance in the vertebrate fauna of
that time and place, as is indicated by the great profusion of individual
remains and specific forms. Although occurring in America wherever
the Cretaceous formation appears, they are so far, more numerously rep-
resented in Kansas than elsewhere. Though not rare in New Jersey,
crocodiles and tortoises outnumber them; but in Kansas, all other orders
are subordinate to the Pythonomorpha. As is now well known since 1868*
the seas of the American continent were the home of this order, while
they were comparatively rare in those of Europe. In the latter country
we have four species only determined by palaeontologists, viz :

Of these I am not acquainted with any which extends its range into
any two of the areas above named, while some of the districts possess
peculiar genera. It is nevertheless premature to draw any conclusions as
to geographical range, as most of the species are known from but few
specimens as yet.
Two genera have recently been discovered in Europe, which have been
thought to be allied, or belong, to this order. One of these, Acrodon-
toswurus Hulke, rests on the anterior portion of a maxillary bone with
part of premaxillary and teeth. These portions are indecisive as to its
affinities. It is from the English Chalk. The second form is the Danu-
dtosaurus of Bunzel, which its describer refers to the neighborhood of
Mosasaurus. It is quite plain after an inspection of his description and
‘figures, that it has no affinity to that genus or to the order Pythonomor-
pha. Itis from Neue Welt, from the Cretaceous, near Vienna.
The present investigations have added some points of importance to
the history of the structure of the order.
First, as to the pterygoid bones. It appears that these elements are
thin plates, having a free laminar termination, and are entirely toothless.
They articulate with the palatines by a process which fits their posterior
emargination. In Hdestosaurus tortor, they are about half the length of
the palatines. They present no indications of ectopterygoid. The bones
named by authors pterygoids, in imitation of Cuvier, are elongate pala-
tines, and the external process extending to the maxillaries, is that seen
in Varani, serpents, etc., and is at no time distinct from the palatines.
It has also shown that the supposition of Goldfuss and myself, thatthe
palatines of Mosasaurus were in contact on the median line, is an error,
and that they are more or less vertical plates, as in Liodon. The dis-
tinction between these genera, then, rests on the codssification of the
chevron bones in the former, and their permanent independence in the
latter ; perhaps the difference in the form of the teeth may also count for
something.
Second, as to the parieto-squamosal arch, which is distinctly developed
in Holcodus tctericus and Liodon curtirostris in its parietal part and ZH.
_ corypheus in the squamosal part. It was quite strong in the species
named.
Third, as to the pelvis. This part, which has been observed by Marsh

in Edestosaurus dispar, is usually perfect in Liodon dyspelor. The
pubes are the only elements united below, forming a weak support to the
abdomen. The ilia are slender, not united with vertebral processes above,
or without indications of such contact. The ischia are the most slender
and directed backwards.
Fourthly, in the hind limb. The femur of tL. crassartus has been
described by the writer, and Professor Marsh asserts its existence in Lio-
don, Clidastes and Edestosaurus. The present collection exhibits both
femur, tibia and fibula of L. dyspelor, and these elements are now first
described. The first mentioned is not larger, sometimes smaller than the
humerus, and has a prominent trochanter, nearly connected with the
head. The shaft is not curved, and the distal end is expanded. The
tibia is a narrow bone expanded at both ends, the fibula is like that of
Plesiosuurus, but wider, or partly discoid. It has been known to ni vtural-
ists but not Sctovariued. Thus I figured it for Liodon taevis,* and Leidy
figured it for an upper Missouri species.+}

and somewhat contracted, and marked everywhere with finer and coarser
strie. Hypapophyses prolonged on the cervicals, the free one of the
atlas with a prolonged keel-like process.
Quadrate bone with long external angle and rather thick anterior ala
with broad rugose margin. A prominent obtuse ridge is continued from
the external angle to the inferior articular extremity, the distal portion
being more acute. A rugose process projects at the point where the pos-
terior hook approaches the body, and is continued as an elevated narrow
ridge, parallel to the previously mentioned, to the distal articular surface.
A. button-like knob appears on the posterior margin of the hook opposite
the meatal part. A. strong ridge extends on the inner face of the bone
from opposite the end of the hook to the base of the great ala. The
distal articular surface presents two planes ; the narrower at the end of
the posterior pair of ridges above described ; the larger considerably less
distal, like a broad step.
The maziilary bone descends regularly in front, uniting with the pre-
maxillary by a minute suture. Its posterior extremity is slender and acute.
The premaxillary is short conic, not particularly prominent. The
palatine bone has a slight expansion on the inner side ; on the outer the
margin is very narrow.

The bones of this species are all light and slender. The elongation of
the vertebre indicate that if their number was of the usual amount, the
animal was of more than usually slender proportions. The position in
which it was found was a partial coil, the head occupying the inside of a
turn of the dorsal vertebra. As compared with H. dispar and ZH. veloz of

the quadrate bones, as well as the larger number of teeth.
Discovered in Fossil Spring cafion in the grey limestone by Martin Hart-
well and Sergeant Wm. Gardner. But one specimen was found, which
includes the greater part of the cranium, with the vertebre as far as the
lumbar region.
EDESTOSAURUS STENOPS, Cope, sp. nov.
Indicated by a large part of the skeleton of one individual, and frag-
ments of two others. The first includes a large part of the cranium, with
both quadrates, and fifty vertebra, including the axis. The characters
are similar to those of the preceding species, but all the bones are more
massive, though of the same dimensions.
The teeth are strongly compressed, with cutting edge fore and aft, and
with the surfaces distinctly faceted ; there are seventeen on the mandi-
ble. The palatine bones are stouter than in Z#. tortor, but the teeth are
not larger, and are probably as numerous, as they are similarly spaced.
The vertebra exhibit round articular surfaces, those of the dorsal region
being rather stouter than the cervical, though the difference does not ap-
pear to be so marked as in the preceding species. The anterior caudals
possess wide diapophyses. The articular faces are a vertical oval, a little
contracted above, sometimes by a straight outline. They preserve a
peculiarly elongate form.
The quadrates, like those of the last species, have a very prominent ex~
ternalangle. They present various differences which may be regarded
as individual ; for example, the edge of the great ala isnot expanded out-
wards, but only inwards; the distal articular extremity is wider, the
posteriorly decurved hook is more contracted, forming a deeper external
concavity behind the external angle. Characters of more importance are
the lack of the two ridges which bound the posterior face of the distal
end of the bone, that face being thus convex instead of concave, and the
process below the meatus is isolated and not continued into a ridge, ex~
cept internally, when it gives rise to the heavy ridge which extends to the
base of the great ala. The button on the posterior aspect of the hook is
wanting, its place being taken by a recurvature of the smooth articular
face along the margin.

A fine specimen of this species was found by Martin V. Hartwell near
Fossil Spring. Portions of a second were found by Lieut. Jas. H. Whit-
ten on a bluff on Butte Creek.
Both the above species are the most elongate in proportion to their
diameter of the order. They are larger in their dimensions than those
next enumerated.

HOLCODUS, Gibbes, Cope emend.
Vertebree without the zygosphen articulation. Palatine bones flat,
alate, its teeth not unequally exposed at the bases, or not pleurodont.
This genus bears the same relation as regards the palatine bones and
teeth, to the genus Liodon that Olidastes does to Edestosaurus, as above
defined. The structure of the caudal vertebrae I unfortunately cannot
ascertain, and therefore do not know whether they are as in Olidastes or
Liodon. It differs from Mosasaurus as it does from Liodon, i. e. in the
horizontal laminiform palatines.
The name which I use for this genus was originally applied by Dy.
Gibbes* of Charleston to a species represented by teeth from the creta-
ceous of Alabama, but of which no other portions were known. The
teeth of the Kansas species now referred to this genus, are very similar
in character to those described by Gibbes, so much go as to lead me to
believe that when other portions of the H. acutidens of that author are
known, they will be found to display the more important features here
regarded as truly distinctive of the genus. Its place is evidently between
Clidastes and Liodon, the pterygoid bones being those of the former, and
the vertical articulations being identical with that characteristic of Lio-
don. In all of the species, traces of the zygosphen appear, but in the:H.
coryphaeus, Cope, the rudiment amounts to a short process directed for-
wards at the base of each anterior zygapophysis.
The species known as yet are of medium size in the order.
HoLcODUS CORYPHAEUS, Cope, sp. nov.
Characters. Cervical and dorsal vertebre with the articular surfaces
depressed transverse, slightly excavated above for the neural canal.
The diapophyses not continued inferiorly to the rim of the cup, on the
cervical vertebre, and not receiving from it a cap of articular cartilage.
Occipital crest much elevated, quadrate bone small, the meatal pit de-
pressed between bounding ridges above and below. Rudimental zygos-
phen not uniting into a keel above. Teeth slender less curved than

cludes the greater part of the cranium and seventeen vertebra, with ribs,
Isolated portions of other individuals were also found in the same region
of country.
The disproportion between the diameters of the cervical and dorsal
vertebre ig more marked here than the species of Hdestosawrus. The
te, though with larger diameter. The cranium
ra are less elong
ively much smaller, the teeth absolutely smaller, though the quad-
5 are of equal size. The general character of the species is
rate
‘ly armed, and less elegantly built.
The hypapophysis of the atlas has a short small keel below. The
1 spine of the azis is elongate, but less so than in the two Hdesto-
saurt, truncate behind, with a median groove into which the anterior keel
of the neural spine of the third cervical vertebra is applied. The dia-
ting surface, and is
pophysis of this vertebrae has a short vertical articula
ug
continued into a longitudinal keel, which disappears before reaching the
edge of the cup. The same process of the a
ritudinal paral-
lelogrammic articular surface.
The swupraoccipital is very thick and is roof-shaped, the keel rising
nearly perpendicularly from the foramen magnum.
The suspensoria are directed both upwards and backwards, at about an
che squam-
angle of 45° in each direction, and support on their extremitic
a
osal bones. These are prolonged, forming part of their appropriate arch.
Tho occipital condyle is transversely oval. The sphenoid bone embraces
as usual the basi-occipital protuberances ; it is not earinate on the
median line below. It sends out on each side near the anterior extremity
a sub-horizontal laminar process.
The quadrate bone is much like that of H. ictericus, but is relatively
smaller. While the teeth in that species are smaller, the quadrate is
larger, hence the difference in the species is in this point quite striking.
The external angle is prominent but very obtuse, and is the summit of a
yery thick obtuse ridge which extends to near the distal articular surface.
The posterior hook is much prolonged downwards and has no button-like
process or extension of the articular surface on its posterior face. This
face presents a strong rib along the meatus and disappearing above the
pit, throws the latter into a depression. This isinereased by the swelling
of the external angular rib. A prominent knob very rugose at the ex-
tremity rises beneath the end of the hook, and bounds a concavity be-
tween it and the external rib.
The latter closes the concavity by curving round towards the knob above
mentioned. A keel rises exterior to the rib, and below it, and continues
into the external angle of the articular extremity. Another very promi-
nent keel extends from the knob beneath the hook to the base of the great
ala. The articular extremity is transverse, and in one plane.
The maatilary bone, is marked with shallow longitudinal grooves. It
supports eleven teeth and has a rather steep premaxillary suture descend-
ing in front. The nareal expansion in front occurs opposite the fourth
tooth,

The teeth are rather long slender and incurved and recurved. There is
a distinct cutting edge anteriorly and on a greater or less part of the
length of the posterior face. The crowns are four or five faceted
on the outer face ; the inner face is more numerously faceted, and striate-
grooved. The section at the base is sub-circular ; higher, the outer face
atter, the inner more convex. The apex is acute and the cutting
edges strong.
The frontal is narrow, and differs from the other Holeodi here described
in having the olfactory groove closed by contraction behind. Both
palatines are preserved. They support twelve cylindric conic teeth which
have recurved apices and striate enamel. The section is a flat transverse
oval, where the external transverse process is given off. The shaft of the
bone is much expanded inwardly with a thickened margin ; exteriorly the
margin is thin, and is nearly followed by the series of teeth, whose bases
are exposed externally, and are therefore pleurodont. The emargination
> pterygoid is very deep.

This fossil was found by the writer projecting from the side of a bluff
in a branch of the Fossil Spring Cafion near the mouth of Fox Cafion.
The bluff was from 80 to 100 feet in height, and the Holeodus was taken
from a position forty feet below the summit, from the yellow chalk.
Honcopus TECTULUS, Cope, sp. nov.
Established on a number of cervical and dorsal vertebra of smaller size
than those characteristic of the other species of the genus. The centra
have not suffered from distortion under pressure. The articular surfaces
are depressed transverse elliptic in outline, with a slight superior excava-
tion for the neural canal. A well marked constriction surrounds the ball.

the inner basis of the zygapophysis and uniting with its fellow of the
other side forming a production of the roof of the neural canal... The
combined keels become continuous with the anterior acute edge of the
neural spine. Thus the form is quite different from that seen in the last
described species, and constitutes a lower grade of rudiment. The fact
that this zygosphenal roof is separated on each side from the zygapophy-
ses by an acute groove, gives the former a distinctness more apparent
than real.
The fixed hypapophyses are short and broad. The centra are not elon-
gate. Those of the anterior dorsals present an obtuse keel below.

In adition to the two individuals of this species procured by Professor
B. F. Mudge in one of his geological surveys, the writer obtained a con-
siderable part of a third from a low bluff on Fox Cafion, south of Fort
Wallace. This includes seventeen lumbar, dorsal and cervical vertebra
including axis, with ribs, and a large part of the cranium with both quad-
rates, occipital and periotic regions, etc. Its characters may be briefly
pointed out as follows :
Articular surfaces of dorsal and cervical vertebrae transverse oval, ex-
cavated above for neural canal; diapophyses not extending below to the
edge of the cup, hence not receiving an area of articular cartilage con-
tinuous with the rim. Occipital crest low, oblique. Quadrate bone
larger, the meatus depressed between ridges, A. button of articular sur-
face on posterior face of hook. Scarcely any rudiment of zygosphen.
Teeth small, much incurved, faceted and striate ridged.
Some characters additional to those already derived from the first known
examples may be added. The mandible supports only twelve teeth. The
palatine bone is shorter anterior to the external process, and longer behind
it than in H. corypheus. In our specimen, the posterior extremity is
broken off, yet. shows no indication of the emargination for the ptery-
goid bone an inch behind the position of its anterior extremity in H.
corypheus. There are ten teeth on the part preserved, four in front of
transverse process (six in H. coryphwus), and six (probably seven) behind
(six in H. coryphwus). The plate is more expanded than in the last
named species, especially the thickened inner margin, which only ap-

proaches the basis of the last tooth ; (reaches the tooth line at the fifth in
HT. corypheus.)
The occipital crest is low and directed obliquely forwards from the for-
amen magnum. The suspensoria are stout, and directed at an angle of
45° in both the superior ard posterior directions. The basisphenotd is
strongly keeled below. The guadratum is like that of H. corypheus in
its massive external angle and ridge, but differs in the shorter hook and
the non-interruption of the groove between the external angular ridge
and the knob below the meatus. The cervical and dorsal vertebra display
the same disproportion in size, observed in H. corypheus.

The specimen of this species obtained by Professor Mudge on the
Smoky Hill River, is the only one known to the writer. The characters
distinguishing it are the following :
Vertebre without rudimental zygosphen. Quadrate bone with plane
surfaces from the proximal articular surface and the external obtuse angled
ridge to the meatal pit ; the latter therefore not sunk in a depression as
the other species.
The frontal bone is like that of H. ictericus, furnished with an open
olfactory groove on the inferior face ; it is wider over the orbits.
A re-examination of the vertebre of the type specimen, which J de-
seribed as having compressed centra, renders it probable that they have
been so modified by pressure as to render their normal shape a matter of
uncertainty.

pophysis with stout inferior horizontal branch, which is capped by an

Description. There is a great disproportion in the sizes of the cervical
aud posterior dorsal vertebree ; the centra of the latter are rather more
depressed than those of the former. They are similar in proportion to
those of the Holeodi and shorter than those of the Hdestosaurt. The
short axes of the articular faces are sub-vertical. The rudiment of zygos-
phen is seen in the slight anterior prolongation of the roof of the neural
canal. The keel of the hypapophysis of the atlas is short and obtuse.
The greater part of the cranium is preserved. The supra-occipital keel
is vertical and furnished at the summit with a plicate knob for the inser-
tion of a Kigamentum nuchw. The thickness of the walls of the bone is
pheus and the suture is a double squamosal
not equal to that in H. cor
?. ¢. with groove along the middle of the edge. The basisphenoid is but
slightly keeled below, and is distally expanded into a horizontal plate on
each side. The parietals are, as usual, confluent, and send off two light
arches postero-laterally for union with the squamosal bone. Between
their origins are two sub parallel ridges which disappear, the transverse
section of the narrow part of the parietals being rounded. The lateral
ridges within the temporal fossee are obsolete, while the convergent angles
lg thin the temporal fossee are obsolete, while the vergent angles
which bound the parietal table posteriorly are strongly marked: This
table is nearly plane and the foramen partetule is large. The frontal is
narrowed in front, and has an elevated keel along its anterior half. The
olfactory groove is not much contracted behind, but is closed by the apex
of the rugose area in front of the foramen parietale.
The palatine bone is narrow and the external margin is very slight, the
bases of the teeth being exposed in that direction. The inner margin is
8, but not so as to be a vertical plate. The
hinder part of the bone is flat and horizontal, with a long maxillary pro-
cess. The pterygoid notch falls opposite the second tooth from behind,
The whole number of teeth is eleven. :
The jaws are represented by the greater part of all of the tooth-bearing
portions. The maxillary bone is shallowly sulcate on the exterior face.
Its proportions are quite similar to those of the H. coryphaus, but the teeth
it supports are larger and fewer, There are none missing from the ex-
tremities of the specimen, the whole number being ten; in ZH, corphy@us
there are eleven. The crowns are incurved, faceted externally, and
striate-grooved internally ; there are cutting edges on front and rear,
both strongest near the apex ; the anterior continued to the base, the latter
wanting on the basal third on median maxillaries. The anterior nareal
expanse marks the fourth tooth from the premazillary suture. The
premarillary bone is remarkable for its shortness and flatness at the
extremity, this part being depressed and scarcely projecting at the lower
margin in front of the anterior teeth. These as usual number four.
much thickened downwards.

Both guadrate bones are preserved nearly entire. They have the same
general character as those of H. icteriews and H. corypheus, resembling
rather the latter in the great length of the posterior hook, which is with-
out posterior marginal button. The proximal external angle is large and
obtuse, and is continued into a prominent thick ridge. The latter divides
below, the thick extremity turning inwards and ceasing ; an acute ridge
putwards and joining the exterior acute extremity of the dis-
is- broad and thick, and not
‘le forwards on the
continuing
tal articular surface. The submeatal knob
prominent, and its extremity turns at an acute ang
1encement of the gi ala. The articular

expansion on a tuberosity on the

LIoDON GLANDIFERUS, Cope, sp. nov.
This species is represented by portions of two individuals from locali-
ties twenty-five miles apart. These are unfortunately in each case only
a cervical vertebra, but they agree in possessing such peculiarities as dis-
tinguish them widely from anything yet known to the writer.
One is an anterior, the other a posterior cervical. The articular sur-
faces are transversely elliptic, and completely rounded above, that is,
neither truncated nor excavated for the neural canal. Their vertical axes
are oblique, 7. ¢., make less than a right angle with the long axis of the
centrum, and the articular surface of the ball is thus carried forward, on
the upper face, to much nearer the base of the neurapophyses than usual,
in the anterior vertebra nearly touching them. The ball is likewise more
convex than in any other species, having a slight central prominence in
the posterior vertebra. There is no annular groove round the ball. In
both, the articular surface of the hypapophysis is truncate and bounded
by an elevation in front, a peculiarity not observed in any of the species
already described. There is no trace of zygosphen in either. In the an-
terior vertebra the diapophyses are nearly horizontal, the posterior por-
tion slightly thickened and oblique. The anterior portion is thinned out
and very rugose above and below, and does not continue its margin into
the rim of the cup. In the second vertebra, the diapophyses are very
large, vertical and with a horizontal portion rising in a curve to join the
middle of the lateral margin of the cup. Neural spine narrowed upwards
keeled behind.

The first vertebra was found by the writer at the foot of a bluff on the
lower part of the Butte Creek ; the second was procured by Professor B.
F. Mudge from a point one mile south-east of Sheridan near the North
Fork of the Smoky River.
It is this species that I compared with the Mosasaurus depressus, Cope,
in a report on the collection made by Professor Mudge (Amer. Philos.
Soc., 1871, 168 Proceedings). The size is similar, but the form of the
articular surfaces is very different.

that is forty or fifty feet in length. The remains representing it consist
of seven cervical and dorsal vertebree, five of them being continuous and
enclosed in a clay concretion.
These display the elongate character seen in ZL. laevis, etc., but the ar-
ticular surfaces are transversely oval, thus resembling the L. ictericus.
they are less depressed than in L. perlatus and L. dyspelor. The cup
and ball of the penultimate cervical are alittle more transverse than those
of the fourth dorsal, and none of them are excavated above by the neural
canal. The last cervical is strongly keeled on the middle line below, and
with a short obtuse hypopophysis marking the beginning of the posterior
third of the length ; the median line of the first dorsal has an obtuse ridge.
There is no keel on the fourth dorsal, but the lower surface is concave in
the antero-posterior direction. The diapophyses on the last two cervical
aud three first dorsal vertebrae have great vertical extent ; the articular
surface for the rib is not bent at right angles on the first dorsal. Neural
arches and spines are well preserved in most of the specimens. There is
no trace of zygantrum. The neural spines are flat, and have consider-
able antero-posterior extent on cervical as well as dorsal vertebre, and
are truncate above. The first dorsal bears a long strong rib.

There are smooth bands around the balls, and the surfaces of the centra
are striate to these.
The depressed cups of the cervicals and anterior dorsals distinguish
this species from the L. validus, L. proriger and H. mudgei. The same
elements are much larger and more elongate than in ZL. ictericus.
It differs especially from these species of Holcodus and from Liodon
curtirostris in the elongate form of the anterior dorsals ; in the latter, they
are much shorter and in three of them at least, the inferior limb of the
diapophysis is turned forwards to meet the rim of the cup, while this
feature ceases with the last cervical in L. latispinus. The articular sur-
faces have planes at right angles to the axis of the centrum and are not
prolonged above as in ZL. glandiferus. The last hypapophysis is very
short, with the anterior margin transverse and elevated as in the last
named species.
In size, this species is intermediate between such gigantic forms as L.
dyspelor, and the lesser LZ. curtirostris.
The type specimens were found by Professor B. F. Mudge, one mile
south-west of Sheridan near the ‘‘Gypsum Buttes.”

Liodon large species near L. proriger, Cope, Proc. Am. Philos. Soc.,
1871, p. 168.
This saurian, which is similar in size to the last, is represented by a
series of dorsal lumbar and caudal vertebree with some bones of the
limbs,
The vertebree are as much distinguished for their shortness, as those of
L. latispinus are for their elongation. The articular faces are but little
broader than deep, and their axes are slightly oblique. They are very
slightly truncate above by the neural canal., The inferior face is some-
what concave in the longitudinal direction. The zygapophyses are stout
and there are no distinct rudiments of zygospen.
The dorsal vertebre best preserved are those in which the diapophyses
reach the middle of the sides of the centra, and have no horizontal limb.
They are narrow and have not extensive articular extremital surfaces.
The lumbars and anterior caudals have round articular surfaces. One of
the latter with strong diapophyses but posterior, is sub-pentagonal in out-
line of cup. The humerus is a remarkable bone having the outline of
that of Clidastes propython, Cope, but is very much stouter, the antero-
posterior dimensions of the proximal extremity being greatly enlarged.
The long diameters of the two extremities are in fact nearly at right
angles, instead of in the same plane ; and the outline of the proximal is
subtriangular, one of the angles being prolonged into a strong deltoid
erest on the outer face of the bone, which extends half its length. The
inner or posterior distal angle is much produced, while the distal ex-
tremity is a flat slightly curved diamond-shaped surface. The fibula is
as broad as long and three-quarters of a disc. The phalanges are stout,
thick and depressed, thus differing much from those of Liodon iectericus.
A bone which I cannot assign any other position than that of femur
has a peculiar form. Itisastout bone, but more slender than the humerus.
The shaft is contracted and subtrilateral in section. The extremities are
flattened, expanded in directions transverse to each other, the proximal
having, however, a lesser expansion, in the plane of the distal end. The
former has, therefore, the form of an equilateral spherical triangle, the
apex enclosing a lateral fossa, and representing probably the great tro-
chanter. The distal extremity is a transverse and convex oval.
This bone is either ulna, femur, or tibia, judging by form alone. Its
‘er length as compared with the fibula, forbids its reference to the
\ the trochanter-like process of the head is exceedingly unlike any
examples of the second bone I have seen. Its reference to femur is con-
firmed by its presence with the caudal-vertebre of a similar species from
near the Missouri River, Nebraska, and its resemblance to the femur of
The dyspelor.

The form of the humerus is something like that of Ichthyosaurus.
Both this element and the femur are remarkable for their small
of the elements of' the anterior
They are scarcely half the dimensions
limb of Holcodus ictericus, and are even less than those of L. dyspelor in
proportion to the animal’s size.
It is unnecessary to compare this species with any but the Liodon pro-
riger. Of this species, I unfortunately do not possess any of the limb
rison on vertebree alone. The type spcci-
bones, and must rely for comp:
men lacks the dorsals, hence the caudals alone remain for comparison.
This shows that they are three or four times as large as the same propor-
y So <
tions of the Z. crassartus. In a smaller specimen of L. proriger, the
dorsals are preserved, but so crushed as to be little available for measure-
ments. One point besides the greater size is noticeable, their generally
more elongate form, and the distinct superior emargination for the neural
canal.
The remains above described were obtained by Professer
B. F. Mudge,
near Eagle tail, in Colorado, a few miles west of the line separating that
Territory from the State of Kansas.
A series of twenty-nine caudal vertebrae with and without diapophyses,
from a bluff on Butte Creek belongs perhaps to this species. The proxi-
mal specimens at least, cannot be distinguished from those of -
Mudge’s collection. ‘The distal ones cannot readily be distinguisicd from
the terminal ones of L. proriger.

This isthe most abundant of the large species of the Kansas chalk.
The writer found a muzzle consisting of premaxillary, and portions of
maxillary and dentary bones, ina spur of the lower blufts of Butte Creek,
and numerous fragments of cranium and vertebra on a denuded tract in
the same neighborhood. Both of these belonged to individuals of smaller
size than the type, the opportunity of examining which I owe to Professor
Agassiz. The more complete Butte Creek specimen belongs to a huge
animal; the size is grandly displayed by a complete premaxillary bone
with its projecting snout, and large fragments of the maxillary. These

furnish characters confirmatory of those already given as above. The
vertebre are remarkable examples of flattening under pressure, without
fracture, some of them having a vertical diameter no greater than one’s
hand. The cervicals are less flattened and give the impression that they
were not transversely elliptic. This is consistent with our knowledge of
the perfect specimen, where it is as described, furnished with vertically
ovate articular surfaces. In this the cup is symmetrical and not distorted,
but the ball is a little compressed by pressure,
The most important addition to the knowledge of this species, furnished
by the Butte Creek specimen, is the character of the quadrate bone.
The external longitudinal angular ridge is very prominent and extends
to the distal end. It supports a hook-like prolongation of the proximal
articular surface, almost as large a one as in Clidastes propython and more
narrowed. The ridge is so prominent as to create a wider face or surface,
behind the basis of the great ala than exists between the latter and the
edge of the articular meatus. This basis is quite convex outward and
embraces a relatively smaller space than in other Pythonomorpha. A
section of the bone at the meatus is subtrilateral with a notch behind.
The distal articular surface is prolonged below the origin of the great ala,
and receives the keeled termination of the external ridge.

The two usual ridges pass inward and downwards from the meatal

The above quadrates are flattened from within outwardly by pressure.
A portion of the palatine bone, supporting these teeth, displays the
characters of the type, viz.: the inner face vertical and deeper than the
outer, and forming a strong parapet of bone on the superior or toothless
aspect. The outer face a little expanded laterally : the bases of the teeth
exposed.
It is proper to add, that the locality ascribed to the type specimen
‘“‘near Fort Hays, Kansas,’’? which was given me on inquiry, is probably
erroneous, Fort Wallace being the point intended.

Proced. Amer. Philos, Soc., 1870, 574; 1871, 168, 172.
This large reptile was first described from specimens sent to the Smith-
sonian Institution from New Mexico. Professor Mudge subsequently ob-
tained it in Kansas, and on my late expedition I had the good fortune to
procure a large portion of another, on a sloping bluff on Butte Creek,
fourteen miles south of Fort Wallace. This specimen is one of the most
instructive which has yet bean discovered, including as it does fifty verte-
bre from all parts of the column, a large part of the cranium with teeth
and both quadrate bones; the scapular arch complete, except lack of
coracoid on one side, both humeri, radius and numerous phalanges of

fore limb ; the pelvic arch complete with one hind limb complete to tar-
sus, with phalanges. The premaxillary is wanting, but the adjacent
suture of the maxillary remains.
The fronto-nasal septum is convex in transverse section. The mazil-
lary bone is much attenuated anteriorly, and supports thirteen teeth.
The ramus mandibult is high and slender; the angle is quite produced,
and the median articulation indicates considerable mobility. The pala-
tine bones are narrower than in any of the species previously described.
They are deeply notched for union with the pterygoids, and the superior
posterior process terminates inan acute cone. In front of the articulation,
the bone is a vertical plate slightly concave on the inner side ; the ante-
rior half is subquadrate in section, the outer face subvertical, the inner,
regularly rounded. The inferior surface is marked with a groove which
passes from the inner side to the outer. The portion on the outer side of
this groove, is on the distal third of the bone produced downwards into a
prominent keel or ridge. The anterior extremity is an acute point. Each
bone bears eleven teeth, all of which have the external faces of their roots
exposed. The bones are curved outwardly from the fourth tooth from
behind ; opposite the sixth there is longitudinal concavity on the inner
face.
The occipital region and suspensoria are not present, but both, quadrates
were found perfectly preserved excepting the thin ala. They present
marked characters, being most nearly allied to those of L. proriger and L.
validus. The proximal articular surface exhibits an obliquity in the
transverse direction. It presents a large external angle which instead of
being nearly at right angles to the axis of the main portion of the surface,
is nearly in the same line. The decurved posterior hook is very short.
The distal articular surface has, like that of other Liodons, a small trans-
verse extent, and is divided by a concavity into two tuberosities. The
outer of these receives at its angle the prominent narrow portion of the
external ridge, which extends from the external proximal angle. The
prominence of this ridge is greater than in any other species except Z
proriger ; it is acute throughout its length and has a gentle sigmoid flex-
ure. The basis of the great ala includes a smaller area than usual and is
continuous with a prominent narrow ridge which proceeds from inside the
metal crest. The metal crest takes the place of the “knob” in such
Mesasauri as M. dekayi, it projects strongly backwards and outwards as
an angle of two ridges ; the inferior being acute and curved and termina-
ting above the middle of the distal condyles. The meatal pit is not con-
cealed between ridges, but is external ; its form is peculiar, being a nar-
row oval, three times as long as wide, directed downwards and forwards.
Thus the characters of this element are well marked among those per-
taining to the other species.
The teeth are not much compressed, and have a cutting angle on the an-
terior and posterior margins, which separate nearly equal faces.
The vertebral centra change in form from the anterior to the posterior

regions. The ball of the axis is round, those of the vertebrae early suc-
ceeding are moderately depressed. The balls of the dorsals are transverse
elliptic with a slight concavity for the neural canal ; the plane a little ob-
lique to that of the long axis, The centra are more depressed posteriorly
where the balls of the dorsals present rounded lateral angles. On the lum-
bars preceding the caudals, the base of the neural canal becomes more
elevated, and the articular faces assume a slightly pentagonal outline.
This form continues as far as our specimens of caudals extend. On three
lumbars, the centra present two longitudinal angular ridges below, at
whose posterior ends the chevron articular surfaces appear on the first
caudals, All present an incised marginal groove to the ball. The sur-
face, especially the inferior, is strongly rugose up to this groove, espe-
cially on the dorsals.
The aais is much shorter than in any other species here noted, where
known. The neural spine has a very oblique superior margin and is ex-
panded behind. The diapophyses are narrow, and continued as vertical
plates to the inferior face of the centrum at its anterior margin. The
diapophyses of the other cervicals have the usual horizontal limb, which
is, however, shorter than the vertical. In the anterior dorsals, they are
directed more obliquely upwards and are longer. These, and all other
dorsals, maintain a connection between the rim of the cup, and the
anterior basis of the diapophysis by a smooth area apparently capped
by cartilage in life, as exists in L. cwrtirostris. As we pass posteriorly
these processes descend, and become narrower, until finally they thin out
and lengthen into the ribless diapophysis of the lumbars. Those of the
caudals are long and subcylindric. Their extremities are deeply striate
grooved. The neural spines of all the vertebre are longitudinaly striate
keeled, The zygapophyses are remarkable for their narrow form and
surfaces. The atlas is shorter on the outer, and longer on the inner face
than in L. validus. This is caused by the fact that the posterior articu-
lar face is not transverse, but very oblique, and instead of being vertical
and narrow, is obliquely longitudinal in its long axis. It is separated
from the inner face by a wide rugose groove behind ; its lower edge sends
a keel downwards. There is no process at the thinned infero-anterior
angle.
The scapular arch was small especially the scapula, which is absolutely
smaller than that of the Holcodus tetericus, a very much smaller reptile.
The posterior margin is thickened, the anterior thinner, and less elevated.
The superior is arched upwards and backwards. The general form is less
oblique than in Z. detericus. The coracoid is twice as large, and is flat
and thin. Its inner margin is regularly convex, the posterior concave
and thin, the anterior thickened. The foramen is present.
The humerus is different in form from that observed in LZ. erassartus, L-
ictertous, Clidastes, etc. It is relatively less expanded proximally and
especially distally ; there is but one deltoid crest, which is proximal and
near one extremity of the articular surface, and disappears into the gene-
1871.] 283 (Cope.
ral plane above the middle of the shaft. The general form is flat, partly
due to pressure. The distal extremity is but little convex and displays
the terminal muscular insertions but little produced. Near the inferior
end there is one external expansion for articulation with the ulna.
The radius is lost. The ulna, or a bone which is like that regarded as
such in several species described by me, has the extremities in different
planes which cross each other obliquely. The proximal is triangular and
very wide, too wide for the humeri in their present state. It is also too
long, leaving but little space for a radius, The distal extremity is as ex-
panded, but much narrower, and presents too articular surfaces, a large
and wide, and a narrow, connected by a wide isthmus. The bone was
taken out near a humerus, but not in position.
The pelvic arch, as above remarked, was found perfect, and with all the
elements in place, with a femur with the head in relation to the acetab-
ulum. The articular extremities are somewhat depressed and do not
precisely fit. The déwm is a straight flattened bone, dilated moderately
at the articular extremity. It is coarsely rugose striate at both extremi-
ties. The dschium is a longer bone than the ilium, is more slender, and
more expanded at the articular extremity, where it is also thickened.
The shaft is curved so as to be sub-horizontal in position ; it shows no
trace of union with its mate. The pudis is a broader bone, with the axis
transverse to that of the body, and sigmoidally curved, first slightly for-
ward then gently backwards. The common suture is about as wide as
the proximal extremity. The posterior margin is somewhat thickened ;
the anterior is produced into a process directed forwards, which is the
homologue of that seen in the Testudinata. Itis connected with the
distal end by a thin concave margin.
The femur is rather more slender than the humerus; the distal ex-
tremity is about as much dilated, the head less so. The great trochanter
is a thick convex ridge with a truncate discoidal articular extremity,
which is nearly separated from the head by a groove. Both extremities
are moderately convex. The jidula is similar to that of other species in
its broad, three-quarters discoidal form. Both articular surfaces are
strongly convex and are continued on the inner side on the thinned inner
border. The external margin is thickened and deeply concave, and with-
out tuberosity. The tibia isa more slender element with sub-cylindric
shaft and much expanded extremities, The proximal is oval and is con-
tinued as a narrow ridge on the inner side, for contact with the corre-
sponding ridge of the fibula. The distal extremity is an equilateral
spherical triangle, of which the inner angle is on a different plane from
the remainder,
The phalanges are slender with cylindric shafts and expanded extremi-
ties, which support oval articular surfaces. Those of the two extremities
appear to be similar. The distal ones are extremely small and flat, with.
expanded extremities,
Of doubiful bones may be mentioned two with flat expanded distal ex-
tremity and thick proximal, bearing an oval articular surface, with an

angulate extremity which terminates in a thin edge. ‘The form is like
that of a narrowed radius of ZL. ¢etericus, but it is much too short for the
ulna, As it was found with the scapula, it is probably a portion of the
fore limb, and hence may be a metacarpal. A somewhat similar but
narrower bone may be metatarsal. A piece which is probably the free
hypopophysis of the atlas, is a transversely elliptic piece with an oblique
smooth articular face at one end. The posterior face rugose, the inferior
with a flat truncate process directed downwards and backwards. If cor-
rectly identified, its great peculiarity consists in its thinness anteropos-
teriorly, and the large process.
In comparing this species with the L. proriger, its nearest ally, I have
already observed the difference in the form of the articular surfaces of
the cervical vertebre, which is in that species vertically oval; the present,
transversely so. The comparison is made between posterior cervicals of
both, which in L. dyspelor are less depressed than the others. As it is
possible that the form in the type example of L. proriger may be slightly
affected by pressure, I compare other points. Thus the palatine bones
are more slender anteriorly, and the outer edge descends lowest in a
ridge ; in L. proriger inner is produced downwards as a longitudinal rib.
In this species there are eleven teeth; in that one, nine. The quadrate
bone of L. proriger presents a longer external angle, and more prominent
external ridge, with smaller space enclosed by the bases of the greater
ala. My statement in a published letter to Professor Lesley, that the ends
of the mandibles were acute, thus differing from LZ. proriger, is an error,
due to my having mistaken the palatines for the dentaries on a cursory
examination in the field. The posterior extremity of these bones in ZL.
proriger is unknown.
The only species whose dorsal vertebrae are known to resemble in the
stoutness of their form those of Z. dyspelor, is L. crassartus ; the mani-
fold differences of the latter will be at once discovered on reading the
description already given.

This specimen does not appear to be quite as large as the type, which
came from Fort McRae, New Mexico. The diameters of the vertebral
centra appear to be larger in proportion to the length of the cranium than
in the Mosasaurus dekayt, hence probably the body had a greater diame-
ter. In estimating its length, reference is had to the relations in size of
the caudal vertebra of the type of L. proriger and to the caudal series of
a small Liodon found on the bluffs of Butte Creek. The caudal vertebrae
are quite similar to those of the former ; in the latter, a series of thirty
centra exhibit very little diminution in size. On such a basis the length
would be about seventy-five feet.
Portions of a second individual of this species or of L. proriger, were
found on Fox Cafion. They belonged to a larger animal, one equal to
the New Mexican first described. Professor Mudge has fragments of still
larger specimens.
The principal specimens above described was excavated from a chalk
bluff. Fragments of the jaws were seen lying on the slope, and other
portions entered the shale. On being followed, a part of the cranium was
taken from beneath the roots of a bush, and the vertebra and limb bones
were found further in. The vertebral series extended parallel with the
outcrop of the beds, and finally turned into the hill and was followed so
far as time would permit. It was abandoned at the anterior caudal ver-
tebre, for more favorable circumstances, or amore persevering excavator-

The outcrop of the stratum was light yellow. The concealed part of
the bed was bluish. Yellow chalk left on the specimens in thin layers
became white or nearly so. The yellow and blue strata are definitely re-
lated in most localities, the former being the superior, but in others they
passed into each other on the same horizon.

SOME PHASES OF MODERN PHILOSOPHY.
By Exi K. PRICE.
(Read before the American Philosophie Society, January 5th, 1872.)
“‘T am a brother to dragons, and a companion to owls.’”’ So Job was
constrained to say in the hour of his great afflictions : so others now say
induced only by speculative philosophy.
The tendency of much of the modern natural and physical philosophy
is to degrade our humanity, and to dispense with the belief of a Creator.
Delvers in a special field are not content to exhibit what they find for the
use of those who are farther advanced and prepared to take a broader
survey from a more elevated height; but they theorize and make their
inductions from facts too few and inadequate for the conclusions drawn.
The result cannot be truth, but error. Theories so built are raised to be
quickly thrown down. They are the least fit to survive in the struggles
of science.
All carefully observed and true facts philosophy must receive and
register for her legitimate uses. But if philosophers be not certain of the
truth of facts, and have not all that are requisite for truthful conclusions,
they violate the fundamental canon of philosophizing : they necessarily
land in error, and bring reproach and ridicule upon philosophers and
philosophy. Much labor and expense of printing are wasted, while stu-
dents are misled, science is obstructed, and it is made necessary for the
lovers of truth in the next to correct the errors of this generation.
I. The first subject to which I would now ask your attention is that of
Spontaneous Generation. Dr. Erasmus Darwin had, at the close of the
last century, ascribed to Nature the power of spontaneous generation ;
and thus concludes :
‘“‘ Hence, without parent, by spontaneous birth,
Rise the first specs of animated earth ;
From Nature’s womb the plant or insect swims,
And buds or breathes, with microscopic limbs.”
[The Temple of Nature}.
‘Organic life beneath the shoreless waves
Was born, and nurs’d in Ocean’s pearly caves.” —[ Ibid].
But he had the imagination of the poet; and his imagination some-
times assumed his facts.
There is a present effort to go a step further, and prove that life can
be produced by man from matter, without propagation from other life ;
and if you add to this the theory of evolution, by which all complicated
life is derived from first simple forms, we have two theories, which, taken
together, will account for all life, without a Creator. There are, however,
certain things, like perpetual motion, so contrary to nature, as not to be
credible, The fact of spontaneous generation has not yet been satisfac-

Price;j [Jan. 5,
torily proved; and, it is believed by those best enabled to form a correct
opinion, will never be proved. The life produced by the experimenter
is, no doubt, but a process of developing seeds or spores, or of hatching
eggs, that exist invisibly in the atmosphere, and within the tube used in
the experiment, and from which they had not been perfectly expelled.
And well it is that life is not, and cannot be, spontaneous, for, if noxious,
and no law of reproduction restrained the increase, there could then be
no hope of its effectual extermination ; but, if depending upon parental
production, when you destroy the parents, you destroy the pestiferous
succession. This was the basis of the confidence of Pasteur in his suc-
cessful researches and efforts to find out and destroy the parasite that
destroyed the silk-worms in France.
It is also the hope of mankind to escape contagious diseases, that pro-
ceed from germs that ever re-produce the same disease, be it small-pox,
scarlet fever, or cholera, or other plague, for the spread of which the cor-
rupted air becomes the fitting propagating medium.
If new generation were possible, there would result confusion ; it should
be bound by no rule if not produced in the course of nature ; there could
never then be scientific classification into genera and species, and all order
and harmony would become impossible. It is a necessary ordination of
the Author of nature that generation should come from a living parent-
age, and that parents should ever produce their like. Such we know to
be nature’s procedure. Such process must proceed by law, that the pro-
geny shall be like their parents, and of different sexes, and such law and
such sure observance of law, imply an intelligent Creator, who never
ceases to watch over his creation. Life has been on the earth in countless
forms, and in infinite multitudes, through nearly all the geological forma-
tions from water deposition, and ever since; but none of that life has
been thought to be spontaneous, except in the imagination of the poet, or
of the fanciful theorist. All except the first of each kind, for which we
infer a Creator, came by generation, from parental germs and ova, as we
must believe from observation; or by fission, which but subdivides life
and thereby multiplies it. It is, however, now announced in this age of
great discoveries that man can produce life where no life was.
Dr. Bastian has made numerous experiments and written a book on
‘‘The Modes of Origin of Lowest Organisms,’’ and believes that he has
produced them de novo, ‘‘independently of pre-existing living matter.”’
But his book makes necessary admissions that must go far, if not quite,
to destroy his theory. All the living organisms which he produced had
been before known as existing in the course of nature, and had been
named, They are called Bacteria, Torule, Vibrones, Leptothria. But
why were these, and but these, produced, unless they had a parentage
through germs containing life? Why not something new? Certainly
these were not new creations of life, but something re-produced that had
before their given law; and it is easier for the scientific mind to believe
that the parental germs had not been removed by the experimenter, than
that he had witnessed a new production of life. This view is well con-

firmed by this statement of the author: ‘‘Bacterta, Torule, or other living
things which may have been evolved de novo, when so evolved, multiply
and reproduce just as freely as organisms that have been derived from
parents,”’ p. 8. Now what living thing or creature in all nature ever
has propagated, or can propagate its kind, except it has inherited that
power from a living parent? From the beginning it has been that the
grass, or herb, and fruit tree, ‘‘whose seed is in itself,” has yielded
“fruit after his kind ;’’? and the living creatures have ‘brought forth
abundantly after their kind,’’ and only so have they replenished the earth.
Professor Tyndall’s article ‘‘ Dust and Disease,’’ is commended to the
student who would learn how all pervading in the air of London are the
seeds of life and of disease. (Fragments of Science, 277.)—Stating the
result of experiments, he says, ‘‘The whole of the visible particles float-
ing in the air of London rooms being thus proved to be of organic origin.”’
(p. 279,) ‘The air of our London rooms is loaded with this organic dust. ;
nor is the country air free from its presence.”’ (p. 285.) And hence, no
doubt, the ova were hatched by Dr. Bastian, or the germs made to grow.
Sir William Thomson in his recent address, as President of the British
Association, (Nature, August 8, 1871,) adds his authority to that of the
opponents of spontaneous generation. ‘‘Science brings a vast mass of
inductive evidence against this hypothesis of spontaneous generation, as
you have heard from my predecessor, (Professor Huxley, ) in the presiden-
tial chair. Careful enough scrutiny has, in every case, up to the present
day, discovered life as antecedent to life. Dead matter cannot become
living without coming under the influence of matter previously alive.
This seems to me as sure a teaching of science as the law of gravitation.”
* * ® “T confess to being deeply impressed by the evidence put before
us by Professor Huxley, and I am ready to adopt, as an article of scien-
tific faith, true through all space and all time, that life proceeds from
life, and nothing but life.’?. Yet he, so true and wise in this induction,
did not close that same address without falling into an egregious blunder,
eliciting instant dissent and derisive laughter, followed by the universal
condemnation of the scientific press. He too would dispense with a
Creator, at least, on this planet, for he made the suggestion that the first
life came to our world by a falling Aerolite, though it came fused by heat !
But that was only to transfer creation to another planet. This suggestion
of course committed the learned President to the extremes of the evolu-
tionary theory, was to say that from such life as could be borne hither by
an aerolite all other life on earth has come and been developed upwards
to man. Of this theory let us next speak, but first pausing to declare
our faith that life came only from God, and by Him alone is ever protected
and preserved.
II. The theory of evolution as announced, seems to have been carried
to an extravagant extreme. Its agencies are chiefly two: natural selec-
tion, and sexual selection. The life that is best fitted to endure will live
the longest ; and the weakest will soonest perish ; and that which man
takes best care of and most propagates is most likely to live in perpetuity,
~)

while that which he destroys, because hurtful, is most likely to perish ;
and this is natural selection, and to a limited extent, it is obvious to all.
The sexual selection is that which the male or female makes when mating.
The latter influence can have no place in the vegetable kingdom, for in
it there is no will to exert selection ; and there is very little of it, indeed,
below man in the animal kingdom ; for what female is there in it, unre-
strained by man that finds not her sufficing mate, be she beautiful or
plain? Nature is not checked in her purpose of multiplication, when
free, for want of masculine co-operation, for it superabounds. The seeds
of life are always superabundant. All the fanciful writing upon this
subject, the motives for the mating of birds and quadrupeds, by the
attractions of symmetry and beauty of plumage or color, seem quite unim-
portant : where all mate sexual selection effects nothing. The real check
to increase comes from want of food, severity of climate, disease, and
enemies, which spare not symmetry or beauty, and not from any failure
to be selected.
Nothing is more certain, however, than that as far as man exercises
a dominion, by the culture of plants and breeding of animals, he does
greatly increase some in numbers and quality, and he diminishes others.
Fle practices great partially. The flowers and fruits, and vegetables and
grains that best please and nourish him, he will most cultivate, and
destroy all things that most obstruct their growth. The birds, fowls and
animals that are most useful and please him best, he also breeds and
greatly multiplies, and he destroys their enemies. The cattle on a thous-
and hills are justly for its use, because they are bred and fed by himself
to do his labor and be his food ; and his care and skill make it sure that
they shall be the best fitted for his purposes. And this is also called
natural selection ; although it is the result of man’s skill exerted upon
nature and the laws that govern nature. Its effect is great, but is not
unlimited, and is subject to reversal when man ceases to exert his care
and skill.
There is truly a law of nature in propagation, that each species, and’
each pair of individuals shall produce a progeny like themselves. Man
selects the parental pairs of the qualities he desires, and his hopes are
seldom disappointed. He repeats the process until he arrives at the
highest perfection in view that is attainable ; hence our fleet race horses,
our strong draught horses ; and also our finest breeds of cattle and sheep,
selected with a view to their qualities for milking, clip of wool, or beef,
or mutton. Thus the wild animals are inestimately improved! And so
with these and other purposes, and the large indulgence of a capricious
fancy, have pigeons, poultry and dogs been improved, or greatly changed
in their varieties, until it is made a question whether such variations have
not been carried to the length of making new species. The success of
such proceeding has been made the basis of a theory so extreme, that it
at once threatens to destroy the classifications of science, and the religious
faiths of mankind. ‘
It is, indeed, also true, that the like inheritable qualities exist in the

human species, and if men and women were as eareful in mating, as men
are when breeding their horses, cattle, sheep and pigs, to consider whethe1
those they select are well endowed with bodily and mental perfections,
the physical and moral qualities of families might also be alike improved ;
though the unattractive among mankind would still not be disappointed
in the opportunity of mating, if they have the means of livelihood or
the ability to win it ; the want of which constitutes the most serious check
to matrimony and the increase of population. But mankind are neither
so careful in selecting what shall be the qualities of the father or mother
of their children, as farmers are of the pedigree of their stock ; nor are
men or women so careful of their own training and feeding, and the preser-
vation of their health and beauty by temperance and exercise, so that they
are more derelict in duty to themselves than to their animals, and the
race has not been improved as it should have been. Yet, it may well be
questioned whether the human race is improved in the aggregate by sexual
selection, since generally men and women do marry, and since the women
who fail to marry from the absence of personal attraction, are probably
outnumbered by those whose personal attractions, combined with their
moral weakness, causes them to become the victims of ‘the social evil,”’
of which sterility is one of the retributions. Yet the race, is undergoing
a constant physical and. moral improvement; but it proceeds from
Christian civilization ; a civilization that does believe in an ever-living
watchful Creator, and that would suffer terrible relapse, if that belief were
lost. This is said on the proof of boundless facts.
If we consider the conditions of all life as found in nature, before man
began to reduce it to his dominion, and the methods of his procedure and
its results, just as the evolutionists have described, we shall be able to
value their scientific significance, and to test the truth of the theory
raised upon the narrated facts. Darwin in selecting his illustrations says,
as to dogs and their various breeds, ‘that some small part of the difference
is due to their having descended from distinct species ;’’ “In regard to
sheep and goats I can form no decided opinion.”” The humped Indian
cattle have a different origin from the European cattle, which are supposed
“to have had two or three wild progenitors.’’ With respect to horses he
says, ‘I am doubtfully inclined to believe, in opposition to several authors,
that all the races belong to the same species.’’ As to fowls, ‘it appears
to me almost certain that all are descendants of the wild Indian fowl.”
As to ducks and rabbits, ‘‘the evidence is clear that they are all descended
from the common wild duck and rabbit.’’ ‘‘Great as the differences are
between the breeds of pigeons, I am fully convinced that the common
opinion of naturalists is correct, namely, that all are descended from the
rock pigeons.’’—Darwin on Origin of Species, p. 30 to 35. Now what
is the import of this? First, that by nature, or the Cause of nature, when
or wherever mau has not interfered to modify, the demarcations of species
have been well and persistently defined. Through all the geological ages
and downward to the time present, the operations of nature, when let
alone were and are simple and true, without tendency to variations, or
&

acting under a power that ever corrected them. The wild progenitors
were without variations; in that state new species were not formed by
process of variations ; nor was there transition by gradual change from a
lower to higher species ; nor do geology and history afford the proof of such
change, and the theory depends upon conjecture asserted against the
truth of our observations and just inferences, that nature has always
operated as we see her now do in those vast domains of ocean, mountain
and forest, that lie beyond the interference of man. With the living
ife of the oceans man can do nothing except slightly to diminish the
numbers of whales and fishes, and there the processes of nature go on
without change ; and so has it ever been in the deep recesses of forest and
mountains yet unpenetrated by man, or, if the scientific adventurer has
penetrated, it has been to leave no trace of his power there. It has been
man only that has disturbed the truthful proceedings of nature ; modified
them for his own benefit.
Again, it is to be considered that all that man has done, he must forever
continue to do, otherwise nature will re-assert her dominion, and undo
all that man had done to mar, or pervert, or perfect her works ; and she
will restore them to their pristine simplicity. This we know she is always
doing, from abundant observations; she makes hybrids unfruitful ; her
ban forbids changes that shall endure ; the seedsman and gardener ever
watch their choice crops, fruits, vegetables and esculents, and must do so,
for they know well that nature ever resumes the attempt to ‘‘cry back ;’’
that is, to return to that condition from which the skill of man has forced
her to meet his own wants, or to please his fancy. Who can reasonably
doubt that if man was to cease to be on the earth that his seeds, and es-
culents, fruits, and all domesticated animals would in process of time,
return to their natural conditions? Human care and culture and pro-
visions ceasing, the antecedent causes of nature would again come into
exclusive operation ; and by her own truthful observance of cause and
effect, the ancient condition of vegetable and animal life would be re-
stored as they were on the face of the earth. Without his stores of pro-
vision and provender and shelter, a single severe winter would cut his
before housed and sheltered vegetables and animals, by frost or starva-
tion, down to about the thirty-seventh degree of latitude ; and half the
variations that have grown up under the training hand of man might
perish at a blow. What man has achieved over living nature may, there-
fore, be considered as an artificial work of but temporary endurance. Dar-
win fully admits this when he says, ‘‘ Natural selection is a power inces-
santly ready for action, and is as immeasurably superior to man’s feeble
efforts as the works of nature are superior to art.’? Ib. p. 70. When let
alone she elects to return to her original conditions.
Of the variation produced by selection in breeding and the better care
of animals, Darwin says, ‘‘the key is man’s power of accumulative selec-
tion: Nature gives successive variations ; man adds them up in certain
directions useful to him, In this sense he may be said to have made for
himself useful breeds.’’? Origin of Species, 40. But what does nature do

when man does not seize upon the offered variations to make them in-
heritable, by bringing together two of different sexes with the like varia-
tions to become parents of a common like progeny, and afterwards pre-
serving only those which most strongly shew the desired variation? The
variation from one parent only would quickly fade out into the normal
character. Those having variations, Darwin says, ‘‘would during ths
first and succeeding generations cross with the ordinary form, and then
they would almost inevitably lose their abnormal character.’’ Tb. 58.
Nature, of herself, does not interpose to seize upon and continue the occa-
sionally occuring variation. She does not select a mate of like variation ;
nor does she develop it to a higher perfection by training or better feed-
ing, and make it the special centre of a favored propagation. Natural
selection, unaided by man, must, therefore be of very limited influence,
if any, towards establishing a change, whether to be called a variation or
a species ; while the change that is wrought by man, would, without his
continuing maintenance, revert to its normal condition much more rap-
idly than it was formed. Again variations left only to nature’s care,
must be such as give increase of strength, otherwise they will die out
from weakness as all monsters do, or breed out to the normal condition.
Tb. 90, 108. The varieties of pigeons have been the products of man’s
care for thousands of years ; but not one-half the eggs of the best short-
beaked tumbler-pigeons would be hatched without his aid to break the
shell. Ib. 38, 90. This shews them degenerate ; a pampered and failing
aristocracy ; who, left to themselves, in a state of nature, would quickly
die out.
And what is the result of the selection of nature even when most as-
sisted by man? Has it produced any new species? For more than three
thousand years before Christ, and ever since, there have been pigeon fan-
ciers who have taken infinite pains in their breeding. Ib. 38. Darwin
says, ‘‘the diversity of the breeds is something astonishing.”” ‘‘A score
of pigeons might be chosen, which, if shown to an ornithologist, and he
were told they were wild birds, would certainly be ranked by him as well
defined species.’’ Ib. 34. Yet are they such? Darwin says, ‘‘the hy-
brids or mongrels from all the domestic breeds of pigeons are perfectly
fertile. I can state this from my own observations, purposely made, on
the most distinct breeeds. Now it is difficult, perhaps impossible, to
bring forward one case of the hybrid offspring of two animals clearly dis-
tinct, being themselves perfectly fertile,” p. 37. Now, if there were a
possibility for nature and man together to create new species, it should
have been in the instance of the long and general experiment with pigeons.
It has at most amounted to producing varieties, in shape and exterior
plumage and appearances, while by the truest test of inter-breeding the
nature of the creature is essentially unchanged. It is probable that the
truth is the same as to dogs, horses, European cattle and fowls, except
as disparity in size has rendered the same test of inter-generation to a
large extent, impracticable. Surely, then, that law which the Creator
has so emphatically imposed upon His creation, He has not himself vio-

lated, in carrying on all His living creation from simple to higher forms
through infinite processes of generation. He who has forbidden the con-
founding of nearly allied species, cannot be taken to have carried on the
processes of generation, in violation of the ban against the confusion of
species, and in disregard of all the classifications science has adopted from
the study of creation, only the better to describe and understand that
creation, On the contrary, it is to be taken that generation has no part
in the work of creation ; but has only her assigned duty, under regulative
laws, to propagate creatures of the same species, of two sexes, to repro-
duce a progeny like unto themselves. All that we can see and know of
creation brings us to such conclusion. To create is one thing, and to
propagate in the parental likeness another. The propagator but fulfills an
assigned instinet that is essentially imperative, except as man is self-re-
strained by over-ruling moral considerations. His function is a very
limited one. The inception of new life, its gestation and growth, and the
measure of that growth are the work of that Higher Life or Being, that
is, the Giver of all life, as we must logically infer ; for every effect must
have its adequate Cause.
The great distinctions of classes, orders, genera and species, as the
proofs stand in geology, history, monuments and living nature, have ever
remained unchanged and wnobliterated ; while variations within species,
have been permitted for obviously good uses to man. The mules that he
breeds do him good service, but mules are not permitted to breed mules.
A theory that would permit a varying generation to thwart this grand
order of life, and that would traverse all these classes, orders, genera and
species by violations of the ban we know to forbid hybrids to breed, we
may simply set down as contrary to nature and impossible, and such
theory demands the clearest and most indubitable proofs, none of which
have been adduced.
The theory is wholly illogical and inherently inconsistent with itself.
The whole drift of the theory is to make generation build up all created
life, with one or a few exceptions, without a Creator. But why any ex-
ception? Only that there shall be a starting point in life; that there
shall be an incipient generator in this mighty process. But this earliest
life must have had a Creator, and the capacity to generate life through all
kinds must have come from a Creator ; yet this theory demands none, at
the beginning, or in any stage of progression, but it obviously pro-
ceeds upon the ground that generation will suffice for all life, and that
life needs no Creator. Yet there is an overruling power, without which
generation could not proceed, without whom there would be no ban
against confusion, and without whom the required difference of sex would
not come into being in the requisite proportion. The reasonable inference
to be made is, that as a Creator was required for the first life demanded
by the Darwinian theory, and for all its processes of generation, and the
after preservation of all creatures born, the same Creator would him-
self create all the creatures that share his protection, in all their various
species, and do so as the world was prepared for them, and was of the

temperature and had the food they required. The first creatures had a
delegated power of generation ; but nothing in nature has shown that
they had a mission to carry on creation to higher levels either of physical
structure, or moral excellence, or of intellectual power.
The whole theory is built upon chance variations from the normal
course of nature, occurring at very long intervals of time. It is, there-
fore, presumably, not the method by which the Creator has built wp erea-
tion, from one or a few of simplest forms of life, into all the elaborate
classification in which we now behold it. Thus, Darwin says, ‘Natural
selection acts only by taking advantage of slight successive variations ;
she can never take a sudden leap, but must advance by short and sure,
though slow, steps.’’ Ib. 190. ‘New variations are very slowly formed,
for variation is a slow process, and natural selection can do nothing until
individual differences or variations occur, and until a place in the natural
polity of the country can be better filled by some modification of some
one or more of its inhabitants.’’ Ib. 171. We have seen that the help
that man can give to promote such variations is very limited, and that
what he effects would soon relapse without his continuing maintenance,
and remain but a variety, and result in no new species ; what else but na-
ture, then, when man is not co-operating, is to ‘‘take advantage of the
slight successive variations ?’? And what does she do? If but one parent
has the variation it will very soon run out in the generative process.
This Mr. Darwin readily admits, and candidly stands corrected by the
North British Review, while monster variations seldom live any length
of time. Ib. 93. Thus the aberrations of nature are so few and far be-
tween, and so soon to disappear, as to afford no adequate ground for the
change of any species, much less suffice to produce all the classes, orders,
genera, and species, into which science has arranged all living things,
from one ora few primary simple types. Nature is, indeed, slow to make
enduring changes, but quick to correct her errors. If jostled in her
processes, she does not make the imperfect product the basis of her
further work to enlarge and perfect her systems of life, that all provided
food should have its fitting consumers. Nature is ever truthful and casts
aside all her products that have been marred upon her wheel, and uses
most those which come most perfect from her hand, and thus her pro-
gress is ever steady, or is improvement towards her best standard of each.
created species, under favoring circumstances ; but is degradation where
unfavorable, or man violates the law of his well-being. This is confi-
dently said after such general survey as all who are intelligent may make,
—all who will lift up their eyes and behold the operations of all living
creation, or read the geological records,—not looking too constantly
downward with limited vision as wedded to pre-conceived theory.
Darwin admits the dearth of facts to sustain his theory, and enters into
explanations why they are not found. He says: ‘To sum up, I believe
that species come to be tolerably well-defined objects, and do not at any
ene period present an inextricable chaos of varying and intermediate
links ; first, because new varieties are very slowly formed, for variation is.
A. P, 8,—VOL, XII—2L,
298 [Jan. 5,

a slow process, and natural selection can do nothing until favorable indi-
vidual differences or variations occur.’’ Ib. 171. But if all the classes,
orders and species come from one or two original and simple forms of
life, there should be everywhere and constantly found intermediate tran-
sition links, at different stages of progress towards the new species, and
presenting an inextricable chaos. This result is parried by the argument
that the process is so slow that it is not seen. The more obvious con-
clusion would seem to be that this transitional process, or “inextricable
chaos,’’ are not seen because never happening. And Darwin candidly
states (Ib. 173), ‘Here, as on other occasions, I lie under a heavy disad-
vantage, for, out of the many striking cases which I have collected, I can
give only one or two instances of transitional habits and structures in
closely allied species of the same genus, and diversified habits, either
constant or occasional, in the same species. And it seems to me that
nothing less than a long list of such cases is sufficient to lessen the diffi-
culty in any particular case like the last.’’ The difficulty was to conceive
how an insectiverous quadruped could possibly have been converted into
a flying bat. But it should seem this would occasion small difficulty to a
theorist who could believe that bats and elephants and man himself,
sprang from an ascidian, a radiate, or trilobite, or some other early sim-
ple form of life. He, in such case, becomes too carefully scrupulous for
his own theory; and he further conscientiously says (p. 198), ‘‘ we have
seen in this chapter how cautious we should be in concluding that the
most different habits of life could not graduate into each other; that a
bat for instance, could not have been formed by natural selection from
an animal which could only glide through the air.’? Let us observe his
wise caution, and doing so we must reject his theory. He gives no proofs
that justify his conclusions.
Again, Mr. Darwin is constrained to excuse geology for affording his
theory but little support. Too few fossil specimens have been obtained ;
too many creatures have perished and left no likeness in the rocks, He
says, ‘‘although geological research has undoubtedly revealed the former
existence of many links, bringing numerous forms of life much closer
together, it does not yield the infinitely many fine gradations between
past and present species required on the theory ; and this is the most
obvious of the many objections which may be urged against it.”? Ib, 415.
But he does not adequately answer this seemingly well founded objec-
tion. He excuses himself by the paucity of facts. Then it may be asked
why has the theory been propounded before adequate facts have been
gathered? Philosophy reserves the privilege of reprimanding her vota-
ries who built their theories upon insufficient facts; and truth compels
her to censure unsparingly. They are not permitted to indulge the am-
bition of theorizing before they have collected adequate materials for
their edifice. Darwin has ranged widely and observantly the realms of
nature, and we follow him interestedly ; but he seems at fault in making
his inductions from the facts he has learned ; has built on an inadequate
foundation ; has made small things important, and overlooked the full

import of the great. If his theory were true, the facts for its support
should exist by millions, and by billions. That his researches have not
produced the facts he wanted, makes them tell more strongly against
him. If all living life, and all that has been, came from first simple forms
by slow changes, through all being up to the classes, orders, genera and
“Species that we find in existence, and to have existed through all the geo-
logical eras, then intermediate links should have been endlessly abundant,
and if but a hundredth part of the fossil kinds had been exhumed, they
should necessarily have revealed the wanted evidence ; living nature should
also have abounded in ample testimony, by endless and inextricable con-
fusion. To reach existing results, the process of change being gradual,
the transition creatures should have teemed in myriad forms, other than
is now seen in fossil or in life.
But why, if there was such immensity of transition as to account for
the astounding changes wrought ; why, if such endless variations were
started in nature casually, or by chance, without reason or motive ; how
)
correlative ; but correlation is not indentity. And the question is a deep
one, what their exact relation is ; it is now one of the cardinal questions
in science. Because of the wide variety of its bearings, let us regard
their most general aspect first.
Grant, as a postulate, the ‘‘conservation of force.’ Then there follows :
Ist, as its corollary, that not only is the total of force in the universe:
never diminished, but, conversely, this totality is never, by physical
causation, ¢ncreased. As apparent exhaustion of force is only its trans-
mutation, so apparent increase of it must also be only transmutation of it.
2d. No change, in the nature or direction of any force, can, in accord-
ance with the second law of motion, be either uncaused or self-caused,
that is caused by the force itself. Every such change must have a special,
sufficient cause. When, then, the laws and tendencies of gravitative,
electric, magnetic, chemical and heat and light forces are known, and »
are found to promote, by preference in all instances, the formation of
compounds of stable equilibrium, by the union of carbon, hydrogen,
oxygen, sulphur, and phosphorts, etc., we must expect this to be wni-
formly the result of their direct action, And, therefore, when we find
conspicuously unstable compounds to be formed of those same elements,
although in the presence of the same general forces, we ought to conclude
the formation of such compounds to be the result of another definitely
acting force. When the force w has been proved always to act in the
line A B, and the force y to act in the line C D, we must be sure that a
force acting in the reverse line B A, or D CG, or in any line intermediate
between B A and DC, cannot be either the force a or the force Yy OF
a force resulting from the composition of X and Y, but must be another
force, say z. Assuming the existence of 2, we may then endeavor to ascer- \
tain its relations to the other forces; and we may also inquire whether '
there may or may not be still other forces of whose composition it is the
resultant. So we ought to conclude that there is a special force, or mode,
or line of force, whose action is the assimilation and new construction
of organizable, protoplasmic, or bioplasmic matter, because the action
so named involves a movement of elements in direct opposition to that
produced by the other known forces, as shown especially and invariably
by the action of those forces upon the same matter, when death occurs.
I may introduce here a remark upon the chemical part of the discussion 3
whether, as a matter of induction, all a priort reasoning apart, we are
warranted in saying that organizable matter is and can be never produced.

by chemical or any other general cosmic forces. Since Wéhler’s first for-
mation of urea from carbonate of ammonia, many years ago, this has
been much argued upon. Numbers of organic substances have since
been made by Berthelot and others, by more or less nearly direct syn-
thesis. But mark this. With the single exception, possibly, though
not probably, of neurin (that exception remaining very doubtful yet,
especially as the substance so designated as made by synthesis, is re-
ported to be crystalline or crystallizable), all the compounds so formed
are not organizable, but what I would call post-organie substances, pro-
ducts or educts of retrograde or downward metamorphosis ; excreted or
secreted,—made in animal or vegetable bodies not by their life-force ag
such in tissue formation, but by its ‘“‘composition”’ or balance with other
forces, in the retrogressive metamorphosis, the approach toward waste and
death. It is not germinal but effete formed matter, to use the words of
Beale, Such, for instance, is even quinia, though not yet made by syn-
thesis. Such may be neurin itself, in the form in which we get it after
the death of an animal, since no tissue is more prone to change soon after
death than the nervous. In fact, if with Lehmann, Moleschott and Hux-
ley, chemists should assert that life is only a property of certain sub-
stances, and, as some chemists at least say, that those substances can be
made in the laboratory, then we must hold them to the test ; and deny the
formation of any of those substances themselves, until they wre shown to
manifest all their properties, including life.
Time cannot be allowed in this paper, more than to allude to the present
aspect of the closely connected question as to the evidence of experiment,
in reference to the origination of minute forms of life. After the contro-
versy (which was very active in the day of Crosse’s electrical experiments)
had, by elimination, been narrowed down to a chronic debate between
-asteur and Pouchet, we are now surprised by its assuming larger pro-
portions, with Owen, Clark, Hughes Bennett and Bastian, coming out as
decided heterogenists, or advocates of abiogenesis. Similar observations
and like arguments, however, come up again and again. No better case
has ever been made out for heterogeny than by Charlton Bastian in his
papers in ‘‘Nature,”? 1870. I need not dwell on the known difficulty of
exactness in such experiments, from the first preparation of the appara-
tus down to the last examination of the results under the microscope: a
difficulty, as regards the total exclusion of foreign particles, pronounced
by some experts to be insurmountable.
We need only observe here that Bastian’s protest against Pasteur’s as-
sumption, that the prior weight of improbability is against the heterogenic
theory, is not warranted ; as the burden of proof certainly does rest with
the heterogenists. It being perfectly well known that no experience
exists of the beginning of life of larger forms, however simple, without
parentage, we may say that since nothing larger than of an inch has
1
1000
ever been known to begin life in an entively inorganic medium, the prob-
ability is vast that nothing smaller than ;,5 of an inch diameter ever
does so. While we are not able to say that it is impossible, those who assert
A. P. §.—VOL. XII.—2N,

Hartshorne. ]
it must bring most cogent evidence. And the legitimate alternative, in
regard to all the heating or boiling experiments, is, whether we are to ap-
prehend in them new evidence of the resistance of some low living forms to
the usually destructive influence of heat, or to assume the total effect
of this, and then conclude that a de novo origination of life has
really occurred. There are many facts which sustain the choice of the
former interpretation ; facts, for instance, concerning confervoid vegetation
in boiling springs, and such as those observed by G. Pouchet and others,
proving the marvellous tenacity of rotiferous animalcular life. Jeffries
Wyman’s experiments, moreover, seemed to show, that though four hours
would not, five hours boiling would, probibit the appearance of any vi-
tality in the materials under his examination. Frankland and Calvert
have since strongly confirmed the same conclusion by their careful ex-
periments. No one, however wedded to heterogeny, can say that
we are yet at the end of our knowledge of the limits of vital resistance to
physical agencies, including heat. But note further: that putting aside
(although Professor Huxley does not) as unjustifiable, the supposition
that it was possible for an observer like Bastian to be mistaken as to the
really organic character of the very minute filaments and sporules, ob-
served by him in tartrate of ammonia or other solutions, under restricted
conditions, we must find in them at least something extraordinarily dif-
ferent from the life which we are accustomed to observe ; since a very
important part of the whole process was the entire exclusion of air; so
that if there was life, it was such only as could exist in distilled water,
or in vacuo. And here, just as in the controversy upon the essential dis-
tinctions between animals and plants, since deoxidation and oxidation,
fixation of carbon and its elimination, are directly opposite processes,
though we may not yet find their separating line, still the line must exist
somewhere. And it would be taking for granted a great deal more than
any evolutionist has a right to do as yet, to suppose, not only that Bas-
tian had thus manufactured sporules and filaments living in airless tartrate
of ammonia, but that all he would need would be some greater variety of
conditions and time to evolve from them the whole system of organized
nature. Bastian himself has not yet asserted this.
A word more about the above named opposition between vital and other
cosmic forces. It may be stated thus: According to the nebular theory
mostly accepted now as the basis of cosmogony and evolution, —the form-
ation of the worlds of our solar system has been and is attended con-
stantly by the integration of matter and the dissipation of force. I have,
in this expression, used Hebert Spencer’s words. The spheres in consoli-
dating from diffused nebulous matter give owt force as heat. But, per
contra, organized beings integrate matter, and at the same time accumulate
force. In the language of Professor Barker’s able discourse on the
Correlation of Vital and Physical Forces, ‘‘the food of the plant is mat-
ter whose energy is all expended ; it is fallen weight. The plant-organ-
ism, in a way yet mysterious to us, converts the actual energy of the
315
1872.] [ Hartshorne.
sunlight into potential energy within it. The fallen weight is thus raised
and energy is thus stored up.”’
As Dr. Barker adds, the force which is stored up is undeniably physical ;
but I remark further, that the process by which it is stored is of another
order, and involves a different kind of physical force movement from that
by which it is evolved and expended. ‘
What more can be made out about this mysterious force of life? Not
mtich as yet; but enough, perhaps, to give encouragement to inves-
tigation. Reduced to its simplest element, namely, the cell, or the physi-
ological unit, life is a process of tneretion and excretion. What goes in as
food is made into tissue, and (after functioning) comes out as waste.
The functioning is secondary to it as /ife, though no doubt in itself pri-
mary under the view of purpose. The organic cell converts crystalloid
atoms or molecules into colloid molecules. Now what is the difference ?
not merely in the fact of different degrees of diffusibility, but in the state
of the particles ; the reason why they are colloidal? May we not con-
jecture, that it may be owing to a differentiated movement of the atoms ?
Clausius and others have long since given reason for supposing that the
particles of all gases are in incessant motion among themselves. May not
these atomic movements of the three gases, nitrogen, hydrogen and
oxygen, all of which are associated with carbon in bioplasm, be in some
manner retained in the integration of the organic cell?
Life-motion is probably not wndulatory, like light, heat and electrical
movement, but rotary or cycloidal. For an analogy, I would allude,
somewhat too boldly, to the theory of some astronomers, of the present
constitution of Saturn’s rings ; of multitudinous small masses incessantly
in motion among themselves. And the occasion for brevity in this com-
munication must be the excuse for crowding, before I conclude, yet other
questionable proposals of analogy ; as of the minute microscopic cell, with
its inward, and outward currents through undiscoverable pores, with even
the incretions and excretions of the sun and its photosphere ; whose out-
ward and inward cloud-currents are now being so laboriously studied.
Somewhat less remote, certainly, is the suggestion of analogy (not iden-
tity) of life-actions with effects of some of the other forces of physical
nature. I would regard sexual union which (except in mere dividuation,
such as the life of a tree in its cuttings, or the fissiparous generation of
animals) is, until heterogeny or spontaneous generation be proved, the
only method of the indefinite continuation of life,—I would regard this
Sexual union as the true analogue of chemical union. The importance
of bi-sexual polarity in organic nature has hardly yet been fully appre-
ciated. Carbon and oxygen uniting give out heat, and carbonic acid
which escapes. Organisms of two sexes, say the pollen cells and germ cells
of a plant combine, and evolve life-force, whose products do not escape,
but remain as organizable and organized protoplasmic matter ; develop-
ing new cells in connection with each other. Yet another analogy with
physical force-action may be presented. It is known that phyllotaxis, or
316
Hartshorne. | [Jan. 19,
the leaf and branch arrangement of plants, follows a spiral law, arithmeti-
cally calculable, and showing a striking correspondence with the order
remarked in the successive distances of the planets of our solar system
from the sun, But what this phyllotaxis still more readily recalls to us
is,—the helix of the electro-magnet ; or, rather, of the magneto-electric
apparatus. As the opposite polarities of the magnet are to the current
of the helix of wire, so may be—of course, we do not say is—sexual
bi-polarity to the spiral phyllotaxis. While a spiral tendency or move-
ment cannot be so clearly traced in animals, yet some indices of what we
may call organo-taxis are not wanting. As opposite leaves are held
to represent a double spiral, and whorls two or more, so the bilateral
symmetry of vertebrates, articulates and some mollusks, and the whorled
form of radiates and colenterates, may present or imitate results of a
similar polar force.
Another analogy, with which physicists may have more patience, is of
a reverse kind, with heat. As a spark of fire sets burning an indefinite
amount of combustible matter within its influence, so a spark of life
vitalizes successively an indefinite amount of viable, organizable material
as food. But the difference is, as remarked already, that while the in-
crement of heat-force instigates the continuous reduction of less stable
conditions of matter to those more stable, the increment of life-force
elevates materials from stable into unstable substances, with constantly
transmuted forms.
To conclude: By no such crude analogies as these can any one imagine
that the mystery of life is to be altogether removed. These remarks are
presented mainly to suggest and show that inquiry into life-force and its
attributes may now legitimately follow methods like in nature those used
in studying the other physical forces; and to expand to some extent the
germinal thought, that, while life or life-foree must yet be always differ-
entiated from the other cosmic forces, it is, like them, a motion, or mode
of motion, whose study is a part of physics—organic physics.
I would add that such a view of the correlation of biology with the
other physical sciences no more interferes with a theistic and teleological
view of creation than does the (now familiar) resolution of many once
called vital actions (as digestion, circulation, blood-aération) into chemical
or physical acts, the results of ordinary forces of nature, which are collo-
cated in the animal body under the conditions of vitality. To analyze is
not to create, or even to show how creation was effected ; much less is it
to afford a negation of the fact of creation itself. Yet, to analyze is
always legitimate in science, so long as it is done accurately, step by step ;
and this, whether it point to biogenesis or abiogenesis, to the origin of
types by interrupted appearances or by evolution.
The discussion of Mr. Price’s paper, read at the last
meeting, being in order, Mr. Cope made the following
remarks :
317
1872.] [Cope.
As the essay read before this Society under the above title, adduces no
facts for or against the theory of Evolution not already known, the writer
does not propose to criticise it as a whole. His object is to correct some
statements of supposed fact, which are germane to the argument of the
essay, in which its author has been led astray by the statements of
others, or want of familiarity with the subject.
The erroneous statements are the following :
Ist. That the gradations of variational and specific form seen among
domesticated animals are peculiar to them, not being found among ani-
mals in the wild state ; and are therefore due exclusively to the influence
of human interference.
2d. That fertile hybrids do not exist in the wild state, and that their
existence between domesticated varieties is therefore evidence of their
‘common origin.
3d. That transitions from species to species, as to form and other essen-
tials, occur neither in the present period nor in the succession of geologic
strata.
4th. That the examples of intermediate forms, or supposed transitional
structures, on which the evolutionists rely, are abnormal or monstrous,
or otherwise insufficient for the use made of them.
These are four very natural popular fallacies, and the present seems to
be a suitable opportunity for exposing them.
First. That graded varieties and unstable specific forms do not exist
outside of domestication, and are due to its influence, ete. To find an
unqualified contradiction to this statement, it is only necessary to refer to
the diagnostic tables and keys of the best and most honest zodlogists and
botanists. It is true that these diagnoses are dry reading to the non-pro-
fessional, yet they embrace nearly all that is of value in this part of bio-
logical science, and must be mastered in some department, before the
student is in possession of the means of forming an opinion. The neglect
to do this explains why it is that, after all that has been written and said
about protean species, etc., the subject should be so little understood.
The fact is thus: That in every family or larger group of animals and
plants, there exists one or more genera in which the species present an
ageregation of specific intensity of form; that is, that species become
more and more closely related, and, finally, varieties of single species have
to be admitted for the sake of obtaining a systematic diagnosis, which will
apply to all the individuals. These varieties are frequently as well marked
as the nearly related species, so far as amount of difference is concerned,
the distinction between the two cases being that in the varieties there is
a gradation from one to the other; in the species, none. Nevertheless,
between some of the varieties, transitions may be of rare occurrence, and
in the case of the ‘‘species,’’? an intermediate individual or two may oc-
casionally be found. Thus it is that differences of the varietal and of the
specific kinds are distinguished by degree only, and not in kind, and are
therefore the results of the operation of uniform laws. Yet, according
[Jan. 19,.
Cope. ] 318
to the old theory, the varieties have a common origin, and the species an.
independent one. To cite examples of what is asserted, the monograph
of the Tenebrionide, by Dr. Horn, in the Transactions of this Society,
especially the genus Hleodes, may be mentioned, or the essay on the genus
Piychostomus, in the writer’s ‘Fishes of North Carolina,’’ in the Pro-
ceedings of the Society, may be consulted.
It is true that in but few of these cases have the varieties been seen to
be bred from common parents, a circumstance entirely owing to the diffi-
culties of observation. The reasoning derived from the relations of dif-
ferences appears to be conclusive as to their common origin, unless we
are prepared to adopt the opposite view that the varieties have originated
separately. As these avowedly grade into individual variations, we must
at once be led to believe that individuals have been created independently:
a manifest absurdity.
But variations in the same brood have been found among wild animals
for example, both the red and gray varieties of the little horned owl
(Scops asio) have been taken from the same nest.
As further examples of gradation between species and varieties, found
in nature, I only have to select those genera most numerous in species
and best studied. Among Birds: Corvus, Hipidonax, Buteo, Falco, ete. ;
Reptiles: Hutenia, Anolis, Lycodon, Naja, Caudisona, Hlaps, Oxyr-
rhopus, ete. ; Batrachia: Rana, Hyla, Chorophilus, Borborocoetes, Ambly-
stoma, Spelerpes, ete. ; Fishes: Ptychostomus, Photogenis, Plecostomus,
Amiturus, Perca, and many others.
These protean genera are not the majority of those known to naturalists,
but are quite numerous. That the variability depends on a peculiar con-
dition of the animals themselves, and not on domestication, excepting in
so far as it produces these conditions, is plain not only from the above
facts, but from those observed in domestication. It is well known that
while pigeons, fowls, cattle, dogs, ete., are very variable or ‘‘ protean,”
the pea-fowl (Pavo) has maintained its specific characters with great ac-
curacy, during a period of domestication as long as that of the other
species named. The same may be said of the Guinea (Nwmidia) and the
Turkey (Meleagris). These facts show that domestication is only a
remote cause of variability.
Second. That hybrids do not occur among wild animals, ete. The
affirmative of this question is no more important to the view of evolution.
than the reverse ; nevertheless, if hybridization be regarded by any as
evidence of common origin, as the author of ‘Phases of Modern Philoso-
phy,”’ ete., believes, then some wild species are undoubtedly descended
from the same parents. There are a few fertile hybrids in nature, though
some animals have been stated to be such without sufficient evidence ; for
example, the Oolaptes ayresii (woodpecker) is thought by Professor Baird
to be a permanent hybrid between the Eastern C. ornatus and Californian
C. mecieanus, and as it occupied the region between the two (Upper Mis-
souri) there is every reason to believe that such is the case, especially as
1872.] 319 [Cope.
it mingles and breeds freely with both the others on the borders of their
range.
Third. That transitions from species to species in the present periods
have not been observed ; nor have they been discovered in passing up-
wards through strata of the earth’s crust.
The all-sufficient answer to this statement is to be found in the imper-
fection of our system of classification already pointed out. Thus, if we
first assume with the anti-developmentalist, that varieties have a common
parentage, and species distinct ones, when intermediate forms connecting
so-called species are discovered, we must confess ourselves in error, and
admit that the forms supposed to have had different origin, really had a
common one. Such intermediate forms really establish the connection
between species, but the question is begged at once by asserting unity of
species, and therefore of origin, so soon as the intermediate form is found ;
for, as before observed, it is not degree but constancy of distinction, which
establishes the species of the zodlogical systems. Transitions between
species are constantly discovered in existing animals : when numerous in
individuals, the more diverse forms are regarded as ‘‘aberrant;”? when
few, the extremes become “‘varieties,’’ and it is only necessary to destroy
the annectant forms altogether, to leave two or more species. As the
whole of a variable species generally has a wide geographical range, the
varieties coinciding with sub-areas, the submergence or other change in
the intervening surface would destroy connecting forms, and naturally
produce isolated species. :
Formerly, naturalists sometimes did this in their studies. A zodlogist
known to fame, once pointed out to me some troublesome specimens
which set his attempts at definition of certain species at defiance. ‘‘ These,’
said he, ‘“‘are the kind that I throw out of the window.’’ Naturalists
having abandoned ‘‘throwing’”’ puzzling forms ‘‘out of the window,”’
the result of more honest study is a belief in evolution by four-fifths of
them.
Fourth. That the ‘‘variations’’ or intermediate types pointed to by
evolutionists in favor of their positions, are exceptional, abnormal, or too
few to be available in demonstration of the origin species in general, ete.
The cases of transition, intermediate forms, or diversity in the brood,
observed and cited by naturalists in proof of evolution, are few com-
pared with the numbers of well defined, isolated species, genera, etc.,
though far more numerous than the author of the article criticised is aware
of. Their value in evidence of the nature and origin of the permanent
forms, is, it seems to me, conclusive, and to a certain extent, complete.
By the inductive process of reasoning we arrive at a knowledge of the
unknown from the known, a process which we act upon in our daily
affairs, and one which constitutes the key to knowledge. It rests upon
the invariability of nature’s operations under identical circumstances, and
for its application merely demands that analysis and comparison shall fix
that the nature of that of which something is unknown, is identical with
Cope. ] {Jan. 19, 1872.
that of which something is known. We then with certainty refer that
something which is known, as an attribute of that object of which the
same quality had been previously unknown.
In application to the question of evolution the following preliminary
facts may be assumed :
1. Many species are composed of identical elemental parts which pre-
sent minor differences.
2. Some of these differences have been seen to arise “spontaneously ;”’
that is, characters have made their appearance in offspring of parents
which did not possess them,—or what is the same thing, are known to
exist in individuals whose parentage is identical with others which do
not possess them.
3. The gradation of differences of the same elemental parts is one of
degree only, and not of kind.
4, Induction: Therefore all such differences have originated by a
modification in generation, or have made their appearance without trans-
mission, in descent.
This induction is one of the forms in which the proof for evolution ap-
pears, though a more cogent argument is that already presented in Chap-
ter I, of the paper entitled ‘‘On the Method of Creation,’ etc., Pro-
ceedings A. P. §., 1871.
The fact that in the majority of species, their origin by descent with
modification has not been directly observed, in no wise invalidates the
above argument. Unless they present positive evidence against such
origin, these are absolutely silent witnesses. He who cites them against
evolution commits the error of the native of the Green Isle, who was
present at a murder trial: ‘ Although the prosecuting attorney brought
three witnesses to swear positively that they saw the murder committed,
I could produce thirty who swore that they did not see it done !”’
Finally, it may be asserted that the Theory of Development is the
only theory of creation before the scientific world at the present time.
The author of ‘‘Some Phases,’’ etc., says, in opposition to it, that God
made the species, and that their gradual evolution dispenses with His in-
terferences and authorship. Will our author explain to us how God made
the species independent from the start? No opponent of development
has attempted to do this, and until it is done, there can be no theory or
doctrine in the field other than that of Evolution. The Evolutionists not
only believe with the author criticised, that God made all things, but they
attempt to show in the field of biology, how He did it.
If they are correct in their interpretation of the facts, there can be, and
is, no interference between their views and the purest morality, and the
most faithful religion.

Influence of Fresh Wood-Ashes on the Growth of Wheat, Potatoes, &c.
By Dr. Grorce B. Woon.
(Read before the American Philosophical Society, February 2d, 1872.)
In a communication made to the Society at their meeting of January
6th, 1871, in relation to the efficiency of fresh wood-ashes in the revival
of prematurely failing fruit-trees, I took occasion to suggest that, upom
the same principles, they might prove equally efficacious in preventing
the failure or deficiency of the wheat crop, so common of late in the old
settled parts of our country. The opinion was based on the large pro-
portion of potassa found in the ashes of the wheat plant, when burned in
the growing state; exceeding as it does twenty times that of common
unleached ashes. Wheat, therefore, requires a very large relative pro-
portion of the alkali for its growth, more than can be derived from an
exhausted soil, even when aided by manure, which, though it contains a
considerable quantity of the salts of potassa, cannot yield enough to the
growing wheat to insure a large crop. But this was mere speculation,
and the question could be decided only by experiment. Accordingly, as
stated in my last communication, I selected an acre of ground, and divid-
ing it into three parts, treated one with ashes alone, another with ashes
Wood. [Feb. 2,
and swamp-muck conjointly, and the third with muck alone; the muck
being applied as ordinary manure, and the ashes sprinkled upon the
ploughed ground at the same time with the sowing of the wheat, and
then harrowed in along with it. This was done early in the autumn of
1870. Even during the same season, the eye could readily perceive the
more luxuriant growth of the wheat where supplied with ashes, and a
line of division between this portion of the lot, and that simply manured,
was very obvious. But the point in question could not be decided until
harvest time next year. Unfortunately, circumstances prevented me from
being present at that time, and I had to depend for the result upon the
report of my agent, in whom, however, I have great confidence. He re-
ported that he gathered the wheat from small and perfectly equal por-
tions of the two divisions, of which one had, and the other had not been
ashed ; finding no such difference between the two ashed portions as to
render it worth while to distinguish them. On separating and measuring
the wheat, he found that the quantity from the ground where the ashes
were used was about double that from the part which had been supplied
with muck alone, and, in relation to general productiveness, was in the
proportion of about 27 bushels to the acre, far exceeding the ordinary
crop, which, though under peculiarly favorable circumstances, it may
sometimes equal 20 bushels to the acre, does not often, according to my
experience and observation, exceed 12 or 15 bushels. It should be men-
tioned that the ground on which the experiment was made was of nearly
equal quality throughout, and very poor.
But I have to mention a fact connected with these proceedings, which
goes still further than anything yet said to prove the efficacy of potash in
the wheat culture. The common poke is a plant abounding in the salts
of potassa, and, therefore, selects for its own growth new and rich soils,
which have not yet been exhausted by cultivation. Upon the heaps of
swamp muck, thrown up on the borders of cranberry meadows in the
process of their preparation, the poke springs up very rapidly and cop-
iously, so as in a short time to completely cover the heaps; and the eye
at once recognizes a muck bed by this luxuriant covering. By gather-
ing and burning this copious crop, we obtained a quantity of ashes re-
markably rich in potassa, containing at least 45 parts of the alkali in 1000
of the ashes, and therefore very nearly equaling in this respect the grow-
ing wheat. To test the quality of some ashes thus obtained, we substi-
tuted it for the common wood ashes in a small space of that division of
the ground which was treated with this material. Within this small
space the wheat grew most luxuriantly, with stems higher and stronger,
and heads longer and fuller than those of the plant in other parts of
the lot; and, when the crop was gathered, the produce was found to
be in the proportion of thirty-eight bushels to the acre, exceeding by
more than one-third that obtained under ordinary wood-ashes. As
the proportion of the alkali in the two kinds of ashes used was the
only point in which they materially differed, the necessary inference
is that the difference in the amount of product was owing exclusively to
—
QO
1872.] ae [ Wood.
the much greater proportion of potassa in the poke-ashes, which
exceeded by more than 20 times that of the wood-ashes; and fur-
ther, that all the effects of ashes in promoting the growth of wheat
are ascribable to the alkali contained in them.
These experiments were made on too small a scale, and. with too little
precision in quantity aud measurement, to authorize any very exact
conclusion as to the effect of ashes upon growing wheat; but they are
sufficient, I think, to prove that the effect is very great, and that the far-
mer may have recourse, with great hopes of advantage, to this agent, if
attainable at a suitable price. If the plan be generally adopted, the ashes
would soon fail; but I have no doubt that commercial potash might be
substituted for them, with at least equal effect; one pound of it being
equivalent, I presume, to about a bushel of the best wood-ashes, Should
the supply of commercial potash fail, recourse may be had to the alkali
as now procured from mineral sources, which will probably prove inex-
haustible.
A few remarks on the mode of using the ashes, or their alkaline substi-
tute, for the promotion of the wheat crop, may be acceptable to those
who, without previous experience, may be disposed to try the measure.
When leached ashes have been used as a dressing for wheat, for which
experience has long showed that they are among the best fertilizers, they
have been applied in the same manner as ordinary manure ; being first
spread upon the surface, and then turned under by ploughing. This method
is correct; because the very small proportion of potassa contained in
leached ashes is in the form of the insoluble silicate, which cannot be
dissolved or carried away by the rains, but which is probably slowly con-
verted, as wanted, into the soluble carbonate by the influence of the root-
lets, which then absorb it. The unleached ashes, containing the alkali in
a soluble state, cannot be treated in the same manner ; as their alkali
would be dissolved by the rain, and carried away, in great measure beyond
the reach of the roots. I have, therefore, caused the ashes to be
sprinkled or otherwise spread, as equally as possible, over the surface of
the ploughed ground at the same time that the wheat is sowed, and the
two then to be harrowed in together. The grain is thus brought into
contact with the ashes, and, when the alkali is dissolved out, is ready to
appropriate it to its own development. But as all the unappropriated
alkali is probably dissolved out, and carried away by the winter rains, I
direct that, in the early spring, another coating of ashes should be
sprinkled over the young wheat, so as to yield it a supply of the alkali
during the growing period.
The same plan, essentially, should be followed in the use of commer-
cial potash. Being extremely soluble, it should first be dissolved in water,
and the solution then sprinkled over the ploughed ground at the sowing
of the wheat, and again in the early spring upon the crop as it is begin-
ning to grow. :
As to the precise quantity of ashes or of commercial potash to be

used, in proportion to the extent of ground, I am not prepared to
say ; but I believe that I have employed from 25 to 50 bushels of the
fresh wood-ashes to the acre. I have no doubt, however, that this
quantity might be greatly exceeded, not only safely but with advantage ;
as shown by the effects, before mentioned, of the poke ashes, which
must have been equivalent in alkaline strength to at least 20 times the
quantity of common unleached ashes.
Every farmer, in whose family the ashes are lixiviated for the preparation
of soft soap, has it in his power to make a little experiment, the result of
which may determine his future course. Let him beg from the women a
bucket full of lye, and, after sowing his wheat in the autumn, let him, by
means of a tin watering can with perforated spout, sprinkle the liquid
equally over a small portion of the field, and repeat the process upon the
same plot of ground when the wheat begins to resume its growth in the
spring. If he find the product of the small plot thus treated greatly in
excess of the average of the field, he may gain confidence to proceed on a
larger scale, and thus perhaps, materially advance his income.
Within about a year, my attention has been attracted to the potato
erop, with reference to the use of fresh ashes in its cultivation, and I
have little doubt that the same treatment may be applied to this as to the
wheat, with at least equal advantage. On consulting the chemical au-
thorities, I found that the stems and leaves of the common Irish potato
are even richer than the wheat plant in the salts of potassa ; their ashes
containing 55 parts of potassa in the 1000, while the proportion of wheat
is only 47. Now the potato crop has of late years, in my neighborhood,
been much more uncertain than formerly ; even, I think, independently
of the disease which has from time to time made so much hayoe with
this crop. It is highly probable that the cause, as in the case of
fruit trees, may be a deficiency in the supply of potassa, and it is
not impossible that the disease which is believed to have its origin in
a microscopic fungus, may, like the worm at the root of the peach,
depend upon the deprivation of the alkali, which may be necessary
to the protection of the plant against these low parasites. To deter-
mine this point, as far as a single observation could do so, I hada
quantity of potatoes planted last spring in rows, a certain number of
which were supplied with fresh ashes in the hills, while the remainder
were treated only with manure. In the rows in which ashes were
used, the plant grew much more vigorously than in the others, and
the product in potatoes was, I believe, about double ; though I cannot
recall the precise figure, in this case.
I have under way, this season, an experiment on the application of fresh
ashes to the wheat crop on a much larger scale than the first ; and my in-
tention is to pursue a similar plan with the potato, at the time of plant-
ing in the spring. Should I be spared to see the results of these trials, il
hope to be able to present a statement about them to the Society. Should
the opportunity offer, I intend also to try how facts will support my

supposition, in relation to the use of common potash as a substitute for
ashes.
I cannot close this communication without referring to the original
subject of the revival of prematurely failing peach trees. I have con-
tinued to apply ashes in the same manner as at first, in the autumn or
spring, or both, to the different kinds of fruit trees; and, I believe, with
uniformly favorable results. The peach orchard, which, four years ago,
appeared to be in a dying state, and had for several seasons ceased to bear
fruit, is now in a vigorous state, and last summer yielded a copious crop.
The old apple orchard, which was so wonderfully revived two years since,
continues apparently, except in the case of a few trees dying from old age,
to hold all that it had gained, though we lost the crop last year through
the destruction of the blossoms by a late frost. The pears and quinces
of which the blossoming period differed from that of the apple, so that
they escaped the frost, were full of fruit; and I was particularly struck
with one old quince tree, which, before the use of ashes had borne scanty
crops of a small, imperfect, knotty fruit, but, last year, under the influ-
ence of ashes, was loaded with smooth and well formed quinces.
T have not yet been able to form any positive conclusion in relation to
the protective effect of fresh ashes against the curculio in the plum tree ;
but I am prosecuting some inquiries in this direction, and hope before
long to be able to solve the question either favorably or unfavorably.
I must confess, however, that Iam by no means sanguine of the former
result.
ON THE FAMILIES OF FISHES OF THE CRETACEOUS
FORMATION OF KANSAS.

A considerable accession of material belonging to several species of this
family, furnishes important additions to our knowledge of their structure,
and enables me to determine their affinities with more precision than
heretofore. The results are of value to the student of comparative anat-
omy, and also to the paleontologist, as they appear to have been the
predominant type of marine fishes, during the cretaceous period, in the
North American seas, and to have been abundant in those of Europe.
The characters already assigned to the family are confirmed by the new
Species discovered, and many additional ones added, as follows :

open. A large lateral cavity is enclosed by the prodtic, the pterotic, the
epiotic, etc. There are no exoccipital condyles, and that of the basioc-
cipital isa conic cup. The pterotic and postfrontal are well developed.
The ethmoid is well developed and slightly narrowed at its anterior ex-
tremity. The parasphenoid is narrowed and elongate; the vomer is
continuous with it and is slightly expanded and then contracted at the
anterior extremity : neither it nor the parasphenoid support teeth in any
of the known genera.
The premaxillary bones are short, and for: but a small portion of the
upper jaw. The maxillary is elongate and simple. The hyomandibular
is rather narrow and does not present an elongate peduncle for the oper-
culum. The symplectic is well developed, entering far into the inferior
quadrate. The latter is a broad bone, largely in contact with the meta-
pterygoid, which is itself a thin plate, not probably attaining the pter-
otic. The superior branchihyals are short rods.
The relations of the supraoccipital, parietals, frontals, etc., cannot yet
be satisfactorily made out, owing to the obscurity of the sutures. Never-
theless the following points may be regarded as probably reliable. The
frontals have a rather broad union with the ethmoid, and are separated
by suture throughout their length. They do not extend much posterior
to the orbits and are succeeded by a rather narrow pair of bones which
extend to above the foramen magnum. ‘These are not united by suture,
but present thickened smooth edges to each other, and appear therefore
to have been separated by a fontanelle. Each is separated by serrate
suture, from a broad lateral bone which is perhaps the pterotic, and cer-
tainly includes that element, as it supports the hyomandibular. It is not
easy to determine what relation the median bones bear to the supraoc-
cipital, but the structure looks a good deal like that characterizing the
Siluride, or, considering the large pterotics, like the Mormyridw plus
the fontanelle. The shorter form of the pterotic in the Oharacinide and
the Cutostomida causes considerable difference in their appearance. There
is no indication of fontanelle between the frontals in Portheus.
Portions of the scapule of Portheus molossus and other species, are
preserved. They have very stout articular surfaces, and although not
complete, have enclosed, more or less, a very large fontanelle. The su-
perior surface is the larger, and is followed below by two others, the up-
per subvertical and small, the lower larger and transverse. These are
surfaces supporting two basilar elements of the pectoral fin. There
were perhaps three basilars, but the base of the coracoid displays no
surface for articulation of a third. The suture with the coracoid crosses
immediately below the lower condyloid surfaces, and passes just below
the scapular fontanelle, leaving in the specimens a fractured surface
which probably supported a precoracoid. There are two fractured bases
of the coracoid, which probably unite below, enclosing a foramen. On
the scapulo-coracoid suture just within the space between the two inferior
condyles is a smooth hemispherical pit of considerable size, Just in front
of it is another of crescentic form. :

A partially complete circle of bones convex on one side, concave on the
other, was found with the remains of two species of Portheus and one of
Ichthyodectes. They look like a sclerotic ossification, and as though
moulded on a globe. They are not segmented as in Reptilian sclerotic
ossifications, nor do they seem to have been completed circles,
The femoral bones, or those supporting the ventral fins are preserved
in Ichthyodectes anaides and a Portheus. They are closely united pos-
teriorly, the inner margins gradually approximating to the union, which
is accomplished by the application of the subcylindrie posterior part of
the bones. In Portheus they are united by a coarse suture. There are
no posterior processes, but the anterior are long and slender. Each is
divided, the inner portion being rod-like ; the exterior plate-like. The
outer is probably the shorter ; exteriorly it rises into an obtuse ridge on
the lower side, and the plate then expands backwards as well as outwards
nearly enclosing a large sinus with the base of support of the fin. The
fin-supporting surface is sub-round, with two exterior and one interior
articular surfaces, and a projection in the middle, which has one or two
articular faces of smaller size. The base of the anterior projections is
‘ather broader in Jchthyodectes than in Portheus.
Three kinds of spine-like rays or supports of the fins have been found
in connection with remains of species of this family, and the proper
reference to their positions and species is as yet in some degree uncertain.
First. The elegantly segmented compound rays originally referred to
Piychodus by Agassiz, and described by me under the species Sawro-
cephalus thaumas, appear to be referable to the genus Portheus, and to be
Supports of the caudal fin.* Secondly. Spines composed of unsegmented
rays closely united edge to edge, and arranged like the fulcra at the base
of the external rays of the caudal fin of recent fishes. That is, the first
very short ; those succeeding, increasing very regularly in length to the
last, which forms the apex of the spine. The obliquely truncated
extremities of these rods form a continuous sharp edge, which is coated
with enamel, and may be straight, or interrupted with low knobs. The
former kind belongs probably to Portheus and the latter to Ichthyodectes,
It is nearly related in character to the spines of Hdestes, the enamel coated
knobs of Jchthyodectes rising into veritable teeth in the carboniferous
genus. These spines are unsymmetrical, and belong either to the pectoral
or ventral fins. To which they should be referred, it is not now easy to
decide. The living allies of the Sawrodontide do not possess ventral
Spines, nor do they exist in Physostomous fishes. In the Siluroids, the
Pectoral fins are supported by strong spines, which remotely resemble
the present ones in their compound character,
Third. There are numerous flat, more or less curved, spines or rays, of
Small diameter compared with the length. One surface is covered with a
thin, gene rally striate-grooved layer of enamel, and one edge is trenchant.
One side of this edge is more or less obtusely rugose, or thickened.

These rays thin out to the extremity, which in some cases at least is not
contracted. These rays are composed of appressed halves, are unsym-
metrical with basal hook, and belong no doubt to paired fins. If those
already described are pectoral, these are ventral, and vice versa. A series
of them found together had much the form of either of these fins, while
their number would identify them with the ventral. In the rays
found together, the first only had a trenchant outer margin, while
several had a rabbet along one side of the posterior margin. T have
already described such a spine as pertaining to the pectoral fin of Iehthyo-
dectes prognathus.
The vertebra in all the species certainly assignable to this group, are
where known, deeply two-grooved on each side, besides the pits for the
insertion of neurapophyses and pleurapophyses, except in the cervical
region where the lateral grooves are wanting. There are no diapophyses.
The caudal vertebra are rather numerous but not so much so as in Amia,
nor are they so much recurved as in that genus.
Until the structure of the posterior cranial roof and of the scapular arch
are fully made out, it is premature to state precisely the affinities of this
family. So far as known they are Isospondyli with some characters of
the Salmonidw, and some of other significance. The large foramen
behind the prodtic bone is more Clupeoid in character. The femoral bones
are more like those of the Plectospondyli, dividing in a measure characters
of the Cyprinide with those of the Mormyride. The yertebre are
Clupeoid, while the mode of implantation of teeth is peculiar.

There are some other forms to be referred to this family, whose char-
acters are not yet fully determined. Thus Hypsodon Agass., from the
European chalk is related to the two genera first named above, but as
left by its author in the Poissons Fossiles, includes apparently two generic
forms. The first figured and described, has the mandibular teeth of
equal length. In the second they are unequal, as in Portheus, to which
genus this specimen ought, perhaps, to be referred. Both are Physos-
tomous fishes, and not related to the Sphyranidw, where authors have
generally placed them. Retaining the name Hypsodon for the genus with
equal mandibular teeth, its relations to Lehthyodectes remain to be deter-
mined by further study of the H. levesiensis.
A species of Jehthyodectes, from the chalk of Sussex, England, is figured
but not described, by Dixon, in the Geology of Sussex.

much resembles a Sawrocephalus, having equal teeth ; while the former
probably includes several species, and possibly genera. The teeth first
referred to it resemble those of P. striata, while others resemble those of
Portheus. An examination of the figures of the mandibles of the last in
Dixon’s work, show that the large and small teeth occupy different areas,
separated by grooves ina manner quite distinct from anything seen in
Portheus ; but, should it prove identical, it can scarcely be regarded as
typical of Protosphyrena, which name, moreover, has never been accom-
panied by the necessary description.
Dr. Leidy applied the name of Xiphactinus to a genus indicated by a
spine, in some degree like those regarded above as ventrals of Sauro-
dontide. It is quite distinct from those assigned to Portheus and Ichthy-
odectes, and may belong to Saurocephalus, as already suggested, or to
another genus.
PORTHEUS. Cope.
(Proceed. Amer. Philos. Soc., 1884, po 178.)
Teeth subcylindric, without serrate cutting edges, occupying the pre-
maxillary, maxillary and dentary bones. Sizes irregular, the premaxil-
lary, medium maxillary and anterior dentary teeth much enlarged. No
foramina on inner face of jaws. Teeth on the premaxillary reduced in
number. Opercular and preopercular bones very thin. Cranial bones
not sculptured.
The fishes of this genus were rapacious, and, so far as known, of large
‘Size. They constitute the most formidable type of Physostomous fishes
known. Three species are known to the writer, one from teeth only,
from the Miocene of North Carolina, but not certainly known to be an
intrusive cretaceous fossil; and two from Kansas. The latter are rep-
resented by more or less numerous fragments of eleven individuals,
three of which possess large portions of the cranium, one almost entirely
‘complete. Two of the remainder embrace jaws, and one a large part of
the vertebral column, with segmented rays. In one, these rays were
found with the cutting compound ray above described ; while the simple
flat ventral rays occur with several specimens. In none have any traces
of symmetrical spinous rays been found, nor strong interneurals capable
of supporting such. In none of the more perfect specimens with crania
have the segmented always been found, but the fossil of P. thaumas,
where they occur, is represented by a vertebral column and its append-
ages, which do not differ appreciably from those of P. molossus.
In the cranium of this genus, there is a well-marked supraorbital rim.
Each opisthotic forms a prominent angle, directed posteriorly on each
‘Side of the exoccipital. The parasphenoid is a stout and narrow bone,
deeply emarginate behind, for the passage of the muscular canal. It has
a transverse expansion in front of the base of the prootic, which rests on
4 backward continuation of the same. This expansion is pierced behind

by two round foramina. The shaft is abruptly contracted in front of the
expansion, and is trigonal in se tion. The prefontal extends down-
wards and forwards, and carries inferior and anterior articular faces ;
the latter vertically transverse. The postero-inferior portion of the
ethmoid bears on its posterior extremity a concave articular face, which
opposes that of the prefrontal. The floor of the brain-case in front is
supported by a vertical style, which is bifurcate above, and rests on the
parasphenoid.
Of the teeth, in general, it may be added that their pulp cavity is rather
large at the base, but rapidly diminishes in the crown. The mode of
succession is by direct displacement from below. The young crown rises
into the pulp cavity, and destroys the vitality of the crown, while the
root is absorbed. Numerous empty alveoli are to be found in all the
jaws of this genus, in which examination will often detect the apex. of
the crown of the young tooth.

Tts condyle is characteristic, being double, and with a foramen between
it and the produced extremity of posterior margin of the pone. It is
slightly separated distally from the third, but the remainder are in close
contact. The radii of the superior lobe of the caudal fin extend at least
as far down as near the end of the third haemal spine from below. The
structure of these parts in the P. molossus, are as in P. thawmas, so far as
preserved.
As some of the spines are not referable to their precise species in this
genus, they may be described here. A large compound spine found in
the blue limestone shale in Fossil Spring Cafion, is composed at the base
of about twenty-six narrow double rods. A few appear between the
others beyond the base making thirty-one altogether. They are very
oblique to the general base, but curve so as to pecome nearly straight,
and enlarge distally. They terminate ina thickened portion which bears
an acute edge, which truncates them obliquely, forming the cutting edge
of the spine. This portion is enamelled ; the edge is slightly convex at
the base, and slightly concave at a point probably beyond the middle.

The third form of spine is represented in most of the species, but
one series of rays with spine may not be referable to any of them. The
latter is flat and curved, the convex edge trenchant beyond the middle.
The posterior edge is obtuse but narrow, and exhibits a slight groove on
one side medially ; proximally there is a shallow rabbet whose floor is
transversely rugose. Several layers of the tissue of the spine beyond the
basal portion are delicately longitudinally striate. The distal half is
broken away ; length of fragment, one foot ; width, 1.5 inches ; thickness
at middle, 5 lines.

Represented by four individuals, one from Fox Cafion, near Fort Wal-
lace, with complete cranium, and many vertebre and radii ; a second from
another part of the same ravine with large part of cranium, and a third
and fourth from lower Butte Creek bluffs, both with fragments of cranium
and other portions. In the first specimen the jaws are perfect and denti-
tion complete.
The premavillary is vertically oval, convex externally, nearly flat within,
and more than half underlaid by an anterior lamina of the maxillary,
The anterior or median margin is regularly convex and exhibits no sur-
face or suture for union with the bone of the opposite side. Its posterior -
margin extends obliquely backwards to beneath the superior articular
condyle of the maxillary and has a ragged margin, though the suture is
squamosal. Its superior margin is deeply inflected in front of the con-
dyle and then convex and thickened. The anterior margin is thick and
rugose with tubercular exostoses. There are but two teeth, which are
very large, and directed obliquely forward; the first is two-thirds the
diameter of the second.
The mavillary is a large laminiform bone, with the upper margin con-
siderably thickened proximally but much thinned distally. It is abruptly
contracted at the distal two-thirds its length, apparently for the attach-
ment of a supernumerary bone. The.extremity is curved sabre-shape
upwards, and has an acute toothless edge. The teeth are, four small, five
large, and eighteen small. These teeth, except the largest, have cylindric
‘bases ; the crowns (and bases of the latter) are slightly compressed or

oval; they are straight and regular, and lean backwards. The middle one
of the five is largest, being six times as long as the small ones, but little
more than half as long as the large premaxillary or mandibular. The sur-
face of the maxillary is rugose with small tubercles on its lower half, and
has shallow grooves for nutritious vessels running downwards and for-
wards.
The mandibular rami are short and deep, and have but little mutual
attachment at the symphysis. They are not incurved at that point,
and were bound by ligament only. There is no coronoid bone and the
articular is distinct. It is short, of a rather irregular wedge shape, and
supports half the cotylus, above which it sends a short acuminate process.
The angular has a prominent angle, like half an ellipse somewhat con-
tracted at the base ; below it has a rough prominent muscular insertion.
The bone extends in a long sword-shaped process, on the inside of the
ramus to beyond its middle ; externally, it is soon covered by the thin
truncate edge of the dentary. This element is very large. From the an-
gular it rises steeply to a coronoid process, which has a slight outwardly
twisted eminence, and then follows a gently concave line to the symphysis.
The teeth are as follows: two large, a transverse groove ; three large,
four very small, nine medium, and two very small; total twenty. These
teeth have straight cylindric-conic crowns, with enamel without strie or
facets. The larger are a little compressed.

The lower jaw was deep, and gave the countenance that bull dog expres-

PORTHEUS THAUMAS. Cope.
(Saurocephalus thaumas, Cope. Proceed. Amer. Philos. Soc., 1870, No-
vember. Hayden’s Survey, Wyoming, etc., 1871, p. 418.)
This large species rests on a specimen without cranium, originally
procured by Professor B. F. Mudge. The parts preserved are not distin-
guishable from the corresponding ones in two individuals obtained by
myself in Western Kansas, which include the greater portions of the jaws

and suspensorial apparatus. These indicate larger animals than those of
P. molossus, and probably indicate the most powerful of the Physosto-
mous fishes, equaling in this respect many of the saurians which were
their contemporaries.
The distinguishing features of the species have been already pointed
out.
The premaxillary is an obliquely oval bone or subpentagonal; the
suture with the maxillary is not toothed, and the anterior or free edge is
smooth, not tubercular as in two specimens of P. molossus. There are
but two teeth, of which the anterior is immense, and the second little
more than half its diameter. The mavillary is stout, and supports in
front four very small teeth, then three very large, of which the median
is largest. The teeth recommence very small and closely placed in the
same line; but as the extremity of the maxillary is lost, the number
cannot be stated.
The dentary is similar in form to that of P. molossus, but has rather
more numerous teeth. Counting from the front there are two large, one
rather small, two larg
smallest from third to ninth, inclusive. None of the crowns are pre-
re, and eighteen small and medium following, the
served, but the alveoli are round or nearly so. The large tooth of the
premaxillary if proportioned as in P. molossus must have projected M.
-0755, or three inches above the alveolus ; the fourth mandibular was but
little smaller.

The various portions of cranial bones preserved are much like those of
P. molossus, but stouter. The hyomandibular is nearly perfect : it is
thin, but has a convex rib extending to its acuminate extremity at the
posterior-inferior angle of the metapterygoid and the superior extremity
of the symplectic. The preoperculum is attached bya thickened grooved
margin, and is not overlapped by the hyomandibular. It extends in a
curved form round towards the angle of the inferior quadrate. Three
elongate bones, closely appressed, I suspect to be part of this bone, with
interoperculum and superior ceratohyal. The last is rather narrow,
and with smooth distal articular surfaces, without suture. The superior
branchihyals are a little like phalanges of Mosasaurus in form, being
sub-similar and expanded at the ends, and quite alternated. The para-
sphenoid is similar to that of P. molossus. The position of the hyo-
mandibular is vertical to the axis of the basioccipital; the superior part
directed forwards.

in Ischyrhiza. They are otherwise as in this genus. Length, M. 04;

A peculiarity of dentition is observable in the two specimens first de-
scribed, and in less degree in P. molossus. A considerable number of
alveole support no functional teeth (though included in the enumera-
tion), but are occupied at some point by successional teeth. In some
cases the mouth of the alveolus appears to be narrowed by ossification,
even where the tip of the young tooth is in sight ; in one case so far de-
veloped as to close up to the projecting apex. In other cases the orifice
is entirely stopped by the ossification, which presents the appearance of
a scar, with radiating lines of pores.
The type specimen was discovered in a denuded area among the lower
bluffs of Butte Creek. The flat cranial and jaw-bone occupied the sum-
mit of a cone of twenty or more feet in height, a relic of the ancient blue
limestone spared from the surrounding denudation. The flat bones had
shed off the water, which, running off on all sides, had formed the cone.
The second specimen came from the Fossil Spring Cation, near the
remains of Liodon curtirostris.

ICHTHYODECTES. Cope.
(Proceed. Amer. Philos. Soc., 1870, Nov. Hayden’s Geol. Survey, Wy-
oming, ete., 1871, p. 421.)
Teeth equal subcylindric, in a single row, sunk in deep alveoli. Pre-
maxillaries short. No foramina at the bases of the teeth on the inner
alveolar walls. Vertebree deeply grooved laterally.
The species of this genus are, so far as known, smaller than those of
the last ; and as their remains are more perishable than those, they form
a less striking object among the fossils of Kansas. They are neverthe-
less, very abundant, especially in species, five of which are now described.
In originally describing this genus, the vertebrae were regarded as not
grooved, in consequence of such vertebre having been discovered along
with the bones and teeth of J. ctenodon. Further examination has satisfied
me that this union is erroneous, and that the bones, if found together,
were accidentally so.
Spines similar to those of the Porthei, but presenting certain differ-
ences, may be referred to this genus. The compound segmented spines
cannot be ascribed to it, but the compound fulcrum-like spines are similar,
though composed of fewer and stouter rods. Each of these, as it termi-
nates at the cutting edge, give rise to a projection, giving it an obtusely
and remotely serrate character. It is rugose with enamel deposit, and
constitutes as effective a weapon of defense as that of Portheus. One,
which is nearly perfect, contains fifteen pairs of rods, which expand at
the base, as do the rays of a pectoral fin. Total length, M. .235; width,
at base, .04; thickness beyond base, .006.
The femoral bones have already been described. The maxillary is not
contracted at the end for a supernumary bone, as in Portheus.
The form of the inferior quadrate is like that of Portheus ; in I. anaides,
the groove for the preoperculum extends low down, and the symplectic
has a wider exposure on the outer face than in Portheus.
In a series of vertebree similar to those of this genus, those included im
the basis of the caudal fin are not more than three in number.

ICHTHYODECTES ANAIDES. Cope. sp. noy.
Indicated by two individuals, one with both dentary bones and teeth,
with vertebrae, the other with many portions of cranium, fin rays, verte-
bre, and other elements more or less separated. The latter were all taken
from the upper face of a spur of a limestone bluff, elevated about five
feet from the ground level, where they were denuded and exposed as on a
table, prepared for the use of the geologist.
It is the largest species of the genus, and the anterior premaxillary
teeth are larger than the posterior. The premavillaries are oblique ovoids,
very convex on the external face, thinning laterally and above. The
superior margin presents a thickening, bearing an articular surface, while
behind it is an open gutter-like inflexion. The large teeth are quite
cylindrical. Both these bones are preserved. But part of the right maa-
illary remains. It is thickened above in front of the condyle and is regu-
larly convex at that point. The teeth are small, there being 10.5 in an
inch. The margin is not concave.
The mandibular rami are preserved almost entire. They are short and
deep, and haye a short angular process, which is relatively shorter than in
Portheus. The margin rises steeply to the dentary, which presents a
narrowed rectangle behind. The alveolar margin has two convexities
with a depression between ; the symphyseal angle is not prominent. The
lower posterior angle of the dentary is quite prominent for muscular in-
sertion. The crowns of the teeth are cylindric, slightly curved inwards.
The dentary bones of the second specimen coincide with these in all
respects.
Thirty-three vertebra are preserved, all deeply two-grooved on the sides.
The ribs are articulated by a sigmoid surface to a broad short element of
a sigmoid form which is inserted in the lateral groove of the inferior face,
or articulated by gomphosis.

The spines already noticed are quite flat, without serrate edge, but with
some rugosities near the edge on one side only. There are no grooves on
the upper side, but the dense bone is delicately striate ; distally grooved.

In this species the premaxillary is more rhomboid in outline than in
the others, and is less convex externally. Of its more numerous teeth,
the first is not larger than the last, differing thus from all others of the
genus, and it is in line with the nearly straight anterior margin of the
bone. It is more compressed than in the other species, whence I origi-
nally placed it in Saurocephalus. To this genus it doesnot belong, as the
absence of marginal alveolar foramina shows. The surface of the bone
is peculiar ; in a minute sculpture of impressed lines, or lines of puncte.
There is a very small articular surface on the superior extremity.

SAUROCEPHALUS. Harlan.
Leidy has pointed out the mode of implantation of the teeth in the
typical species of this genus. The mode of succession of the teeth has
not yet been indicated, but is well displayed in a specimen of the jaw of
S. arapahovius, Cope. It is known, from Harlan’s description, that a
large foramen issues on the inner wall of the jaw, opposite each root.
The fractured ends of the specimen exhibit the course of the canal which
issues at this foramen. It turns abruptly downwards between the inner
wall of the jaw and the fang of the functional tooth, and not far from
the foramen. Its course is interrupted by the crown of the successional
tooth. This is situated obliquely as regards the long axis of the jaw.
It is thus plain that, the successional appearance of teeth is different
in this genus from what I have described in the two genera preceding.
In them the foramen is wanting, and the young crown rises within
the pulp cavity of the functional teeth, as in the Crocodilia. In
this genus, on the other hand, it is developed outside of the pulp
cavity and fang of the old tooth, and takes its place as in many
Lacertilia and in the Pythonomorpha, by exciting the absorption of the
latter. The obconic form of these fangs in Saurocephalus is appropriate
to such a succession, and their great length seems to preclude the nutri-
tion of the young tooth from their bases. The use of the foramina on
the inner face of the jaw is thus made apparent, viz., the nutrition of the
successional teeth from without. I cannot trace the canal below the
crown of the young tooth to the base of the pulp cavity of the old tooth ;
and there are canals in the jaw, below the latter, one of which probably
carried the dental artery.
Species of this genus are less abundant in the part of Kansas examined
by me than those of the preceding genera. Two only have been observed
up to the present time, as follows :

Established on a portion of a maxillary bone, with a part of a suture,
perhaps for attachment to a supernumerary maxillary. The size of the
species is nearly that of S. lanciformis, and the crowns of the teeth are
rather short, as in that species, and less elongate than in S. phlebotomus.
The teeth are very closely set, and the alveoli are separated by very nar-
row septa. The crowns are expanded, so that the edges overlap in some
cases. The form of these is much compressed, width about equal to
height, the edges convex and acute. The enamel is smooth and without
facets. The roots are without the facets, shown by Leidy to exist in
8. lanciformis, and appear to be longer than in that species, exceeding
the length of the crown nearly four times. None are, however, perfectly
exposed for complete measurement. As usual, there is a large foramen
opposite each fang, below the inner alveolar margin, and between the
latter and the series of foramina the surface is slightly convex and mi-
nutely rugose.

PACHYRHIZODONTID &.
This family of Physostomous fishes differs from the last in the nature
of its dentition. Instead of elongate conic fangs sunk in deep alveoli, it
has shorter and stouter fangs occupying alveoli, of which the inner side
and part of the anterior posterior walls are incomplete. The teeth are,
in fact, more or less pleurodont, but the extremity of the root is received
into the conic fundus of the alveolus.
The premaxillary bones are well developed, but the maxillaries are
more so, and enter largely into the composition of the border of the
mouth, There is a well-developed angle of the mandible, but no coro-
noid bone is preserved in the specimens. The coronoid region is, how-
ever, broken in all our specimens. The other characters of the family
are not determinable from our imperfect materials.

PACHYRHIZODUS.
Dixon’s Geology of Sussex, 1850, p. 374.
This genus was established by Prof. Agassiz, on a jaw fragment from
Sussex, England, with avery brief description. The Kansas remains
resemble this fragment in their corresponding parts, and I refer them to
the same genus for the present.
The genus as seen in our fossils, is defined as follows :
Muzzle flat; premaxillary bones rather long, with two large teeth to-
gether, near the anterior end, behind the usual external series. Maxil-
lary and mandibles with a single series of simply cylindric curved teeth.
Mandibular rami closely articulated by ligament.
The teeth in this genus bear a superficial resemblance to those of a
mosasauroid genus. Their mode of succession appears to be as follows :
The crown of the young tooth was developed in a capsule at the base
of the crown, or on the inner side of the apex of the thick root. The ab-
sorption which followed excavated both the former and the latter, but
the crown was evidently first shed. Finally, the old root disappeared,
and when the new one occupied the alveolus, it left a free separation all
round, Finally, on the accomplishment of the full growth of the root,
it became anchylosed to the sides of the alveolus. The pleurodont posi-
tion of the tooth facilitated the shedding of the root very materially.
The genus Conosaurus, Gibbes, from South Carolina, is, perhaps allied.
to this one. Its dentition is fully described by Leidy, who changes the
name to Conosaurops, mainly on account of the inappropriateness of the
Greek Luvpos toa fish. This word was, however, employed by the an-
cients to designate a fish, and the only use made of the word out of com-
position, by modern zodlogists, is for species of that class, so that it does
not seem improper to use it here.*
Three, perhaps four, species left their remains in the strata examined
by the expedition.
PACHYRHIZODUS CANINUS. Cope. sp. nov.
Established on portions of, perhaps, two individuals, which embrace
one nearly complete maxillary bone, two premaxillaries of opposite
sides, two nearly perfect rami of the mandible, with numerous other por-
tions in a fragmentary condition.
These indicate a cranium of about a foot in length, by six and a half
in width, oval in outline, with moderately obtuse muzzle. The man-
dibular teeth are directed somewhat outwards ; the premaxillary is hori-
zontal in front, and the maxillary narrow. From these facts I derive
that the head was probably depressed, as in the modern Sauri, and very
different from the prevalent compressed form of the Porthed and allies.
*The case appears to me to be different with the name Jschyrosaurus, which I proposed to
replace with Jschyrotherium (Leidy). The latter was given to a genus of saurians, under the
supposition that it belonged to the mammalia, and the termination, theriwm, devoted to this
group of animals by meaning and custom, cannot be applied toa sauriam by any stretch of
metonymy or charity,
1871.] 345 [Cope.
The premavillary is several times longer than wide; posteriorly it
is a subvertical plate ; anteriorly it terminates in a narrow obtuse por-
tion. Just behind this portion it is enlarged on the inner side, forming a
knob, whose upper surface supports the articulation with the ethmoid.
It bears the two large teeth below, on a common elevation of the jaw.
The outer margin of the bone supports ten sub-equal teeth, which are one-
third smaller than the posterior pair. The outer alveolar ridge is a little
more elevated than the inner, though a little less so than on other bones
which support teeth. The external face of the bone is nearly smooth,
and the inner unites with the maxillary by striate squamosal suture.
The maxillary preserved is nearly perfect, and may belong to another
animal; its depth coincides with that of the premaxillary. It is quite
elongate, about nine times as long as deep, perhaps a little more. It sup-
ports forty-two closely packed teeth, not all in functional service at once.
The distal end is contracted and grooved and ridged on the inner face, as
though for union with a supernumerary bone. The external face is lon-
gitudinally striate on the posterior half, the striz running out to the mar-
gins, forming sharp rugosities on the alveolar border. The superior
(palatine) articular surface is more than one-fourth the total length from
the anterior extremity ; it is narrow and somewhat lens-shaped. Both
behind and in front of it, strong striae run from the outer to the inner
side of the superior margin, sub-longitudinally. Posterior to the superior
articular surface on the outer face is a swelling like a muscular impres-
sion, from which grooves and keel extend posteriorly. The bone is con-
“cave on the outer face in front, to accommodate the os premaxillare.
The mandibular rami are abruptly incurved at the symphysis, which is
not serrate, is sub-round, with an emargination entering from the inner
inferior side. The dentary bone is much narrowed behind. The angular
bone extends anteriorly on the inner face to the end of the posterior, two-
fifths of the dental line. The ramus is not very deep at the coronoid
region. The articular cotylus is composed more largely of the angular
than the articular. Its long diameter extends inwards and backwards,
and is strongly convex ; in the transverse direction, slightly concave.
Below and in front of it the lower margin of the jaw is acute. The angle
is oval and rather small, it is prominent on the middle line on the inner
‘Side, the edges are thin, the upper curved outwards, concealing part of
the cotylus. There are twenty-nine teeth on the dentary, whose sizes
diminish towards its extremities. Their roots are very large and longitu-
dinally striate and porous. Opposite the interval between the first two
teeth, there is a tooth exterior to the general row, and another on its in-
ner side. They are not enlarged.
No teeth are preserved except on the maxillary. These are not very
» elongate cones, with round section, and well curved inwards. Dense ex-
ternal layer entirely smooth.

CORRELATIONS OF COSMIGAL AND MOLECULAR FORCE.
By Purny Earie Crass,
Professor of Physics in Haverford College.
(Read before the American Philosophical Society, February 16th, 1872.)
If it be granted
1. That all forms of terrestrial organic energy are transformed modifica-
tions of solar radiation ;
2. That centrifugal and centripetal energies tend continually to equilib-
rium ;
3. That the kinetic energy of a perfectly elastic medium under constant
pressure, bears a definable ratio to its kinetic energy under constant
volume ;
Then the kinetic energy of dissociated water should be, approvimately, to
the kinetic energy of terrestrial revolution, as the mass of the earth, is to
the mass of the sun.
And the energy of hydrocarbons should be, upproximately, to the energy
of dissociated water, as elastic energy under constant volume, ts to elastic
energy under constant pressure.
For the measures, of the energy of gaseous combustion, and of the
energy of orbital revolution, are, respectively, the mean height of oscilla-
tion excited by the igneous energy of the combustible compound, and
the mean distance from the sun at which the earth is sustained in its
orbital revolution. It is evident, from the well known laws of elasticity,
that if a perfectly elastic body were lifted, in vacuo, to any given height,
and then let fall, it would rebound to the height from which it fell, and
this oscillation would be perpetual, unless disturbed by extraneous forces,
in the same way, and for a similar reason, that the earth continues its
elliptical oscillation about the sun. Inasmuch as the total radiating force
is considered in each instance, [the time consumed in storing up and in
liberating the accumulated solar energy being left entirely out of ques-
tion, | the element of velocity is not involved in the preliminary deter-
mination. It may, however, be subsequently ascertained, if desired, by
the formula,
avo gh.
It is evident that the dissociated oxygen and hydrogen tend to expand,
in consequence of any liberated interior energy, under constant exterior
pressure, while the hydrocarbons are restrained by the cohesive forces
which tend to maintain a constant volume.
For the purpose of testing the accordance, both of the postulates and
of the conclusions, with the facts of observation and experiment, it might
be deemed sufficient to confine attention exclusively to the lightest and
most elastic gas, and to the lightest and most volatile liquid. But I
believe the same principles, with simple modifications, are applicable to
all forms of matter, and I have already extended the investigation, with
some encouraging results, to inorganic elements and compounds. I sub-
join, from Muspratt’s Chemistry, all the elements and products involved

THE HERSCHELL-STEPHENSON POSTULATE.
By Purny Harte CHAsE.
(Read before the American Philosophical Society, March 1st, 1872.)
Of the three postulates which I submitted to the Society at its last
meeting, I presume the first will generally be considered the most ques-
tionable. The hypothesis of Herschel and Stephenson, that the coal con-
sumed under our boilers merely imparts, to the steam, solar energies .
which have been imprisoned for ages by the molecular attraction of the
carbon particles, has been commonly accepted as a beautiful poetical
fancy, having, perhaps, some indefinite foundation in truth. Few per-
sons, however, can have indulged the expectation that so vague asurmise
would ever yield any satisfactory numerical results, and it will not be
strange if even the close coincidences to which it has led me, may be
regarded by many as merely accidental.
The following comparisons show the character of the agreement
between estimates of solar distance, mass, and parallax, based upon
various chemical and astronomical observations :

The reaction of the elastic atmospheric particles, in their continual re-
bounds from the earth’s surface, under tidal, thermal, chemical, and
molecular influences, should contribute, in connection with the motion of
revolution, to a rotary motion in the earth itself. The following coin-
cidences, at the boundary lines of the interior (Telluric) and exterior
(Jovian) planetary systems, seem to render it probable that a reference to
centres of oscillation may ultimately account for the masses, order of ar-
rangement, and times of rotation, of the several planets and satellites, as
well as for their period of revolution.

FURTHER APPROXIMATIONS TO THE SUN’S DISTANCE.
By Puiny EarLe CHASE.
(Read before the American Philosophical Society, April 5th, 1872.)
If it be true, as is commonly and very plausibly supposed, that molecu-
lar and cosmical laws have many significant analogies which are yet un-
discovered, it may be well to seek for such analogies wherever we may
reasonably hope to find them.
The height of oscillation which I have assumed as the measure of the
igneous energy of combustibles, is less, and the resulting estimate of
solar mass and distance is greater, if the. combustible is dense, composite,
or of small specific heat, than if it is rare, simple, or of great specific
heat. It seems likely that even hydrogen, the most volatile of all known
substances, may have undergone some condensation and loss of specific
heat, and that, therefore, my first estimates by flame analysis * were all
slightly in excess. This opinion is the more probable, from the fact that
the mean of the most recent astronomical estimates of solar distance, is
nearly one per cent. less than the mean of the flame estimates.
In searching for some clue to the coéfficient of condensation in hydrogen,
if we accept the hypothesis that the luminiferous ether is a perfectly
elastic material medium, we may, perhaps, be able to detect some im-
portant relations between the velocity of luminous or thermal undulations,
and the velocity of oscillations which are directly traceable to gravitating
action. In the primary radiation and subsequent double concentration
of exploding hydrogen, there is not only a joint attraction of the gaseous
particles for each other and of the whole for the earth, but there is also
a generation of luminous vibrations, with a velocity such as would be
2
produced by a gravitating force g = . . Equivalent velocities may be
generated by masses of different magnitudes, provided the motion is
orbital with radii varying as the masses, or the fall is virtually continued
to the centre from heights equivalent to twice those proportionate radii.
With these preliminary considerations I invite attention to the following:
coincidences :
1. At the centre of oscillation of the extreme excursion of exploding

Is it possible that there can be anything deceptive in these figures,—
that any bias of unsuspected prejudice may have blinded me, or that I
have been misled by mere fortuitous resemblances? The question
whether there is not some conception of force which will unify centrifugal
and centripetal, luminous, thermal, and gravitating action, is continually
recurring ; the accordance of Faraday’s ‘‘lines of force’’ with lines of
perfect fluidity, and the fundamental equation of oscillation, favor an
affirmative answer; the increasing popularity of the theory that matter
is nothing but force, prepares the way for every conceivable approxima-
tion and identification of molar and molecular laws.
If the undulations of light have any influence upon the gravity of
bodies, the velocity of light being nearly uniform, its influence should
tend to communicate a velocity as nearly like its own as gravity and.
' inertia will allow, a tendency which is presumably most manifest in the

GENERAL RELATION OF AURORAS TO RAINFALL.

In order to ascertain if the parallelism, which I have pointed out be-
tween the daily rainfall and the frequency of auroras, can be traced in the
annual curves, [ have constructed the following table of normals, from
data furnished by Lovering’s Catalogue of Auroras, and Loomis’s Meteor-

INFLUENCE OF METEORIC SHOWERS ON AURORAS.
3y Pror. Puiny EARLE CHASE.
(Read before the American Philosophical Society, May 16th, 1872.)
Professor Lovering’s discussion of the periodicity of the Aurora Borealis
(Trans. A. A. 8. V0. X., Part I.), not only exhibits maxima and minima
of frequency at periods corresponding to general minima and maxima of
rainfall (see above), but it also furnishes evidence of a tendency, in other
great atmospheric disturbances, to increase auroral displays.
In preparing the following table, I first took the second means of
Lovering’s Table LIT. (containing 10816 auroras, arranged according to
their frequency on each day of the year). After grouping the results in
five-day periods, I calculated the ratio of each ordinate to a mean ordinate
of 100. Against each ordinate which corresponds to a supposed meteoric
period, I set the initial K. (Kirkwood’s ‘‘ Meteoric Astronomy’’), or W.
(Wolf, cited by Lovering, p. 221).

The table, as well as the accompanying curve, exhibits the following
peculiarities :
1. The principal maxima occur near the equinoxes, and are apparently
due to the favorable position of the earth for the development of circulat-
ing electric currents.
2. There is an evident grouping of meteoric displays in the vicinity of
the maxima and minima.
3. The grouping is more strongly marked upon the ascending, than om
the descending sides of the inflections.

4. The principal secondary maxima (in February, October, November

5. Nearly all of the apparent exceptions to this general accordance are
occasioned by the rapid decline of the general curve, which is so great as
to veil the subordinate maxima, when five-day means are taken.
Of all the meteoric ordinates suggested by Kirkwood, including those
which he regards as doubtful, three correspond with auroral minima,
eight with increasing auroral displays, two with maxima, and only two:
with ordinates of diminishing auroral frequency. The two exceptional

ordinates become normal if we examine the daily curve of second means,
which shows subordinate maxima on April 19th and April 24th.
Of the meteoric ordinates suggested by Wolf. four correspond with
minima, nine with ascents, seven with maxima. and six with descents in
the auroral curve. Of the six apparently abnormal ordinates, only two,
those of March 31st and Nov. 19th, are on descending inflections of the
auroral daily curve of second means.
There seems, therefore, good reason to look for an increase of auroral
displays, soon after every meteoric shower.
PLANETARY ILLUSTRATIONS OF EXPLOSIVE OSCILLATION.
By Puiny EARLE CHASE.
(Read before the American Philosophical Society, May 16th, 1872.)
The secondary centre of gyration in an exploded gas, on its return
towards the centre of gaseous mass, being, as I have shown, at “i
(h representing the extreme excursion consequent on the explosion), we
may reasonably expect, by referring the planetary masses to similar
} primary and secondary centres, to obtain evidence relative to the proba-
bility of the hypothesis of molar and molecular correlations. Whether the
nebular hypothesis be true or false, the planets are oscillating under the
combined action of centrifugal and centripetal forces. In their continual
virtual fall towards the Sun, they are subject to such disturbances as arise
from their mutual interaction, and should, therefore, tend to arrange
themselves somewhat like the particles of an exploded gas. I submit the
following exemplifications of such a tendency, the calculations being
generally based upon the hypothesis that the planets are either in con-
junction, or nebulously diffused along the entire line of their orbits.

SOLAR AND PLANETARY ROTATION.
3¥ Puiny EARLE CHase.
(Read before the American Philosophical Society, May 16th, 1872.)
The similarity in the length of day, between the principal and sub-
ordinate planets, both in the intra and the extra-asteroidal belt, is so
obvious, that many attempts, of which Kirkwood’s is the most satisfactory,
have been made to formulate it.
Ihave long thought that there is some simple explanation for the
rotation, as well as for the revolution of the heavenly bodies. My recent
investigations of explosive gyration, have yielded some interesting results,
which, from their relation to the most important bodies of our system,
encourage me to hope for further and more minute developments of a
like kind.

Harth, nearly :: the equatorial value of g at the Sun : the equatorial
value of g at the Earth.

between the centres of two adjacent atoms, will be a mean proportional

The closeness of ae harmony, pointed out by Kirkwood, between the
Woltfian and Mercurial cycles, is very interesting. In some respects the
position of Mercury is more nearly pivotal than that of either of the
other planets. Its centre of explosive oscillation, relatively to the Sun,
is near the limit of the Sun’s possible atmosphere. (4.887

greater than the radius of the centre of oscillation (.3333) of the Earth’s
disturbing action upon the Sun. That centre of oscillation is, in its turn,
near the centre of the counterpoising moments of inertia of the Sun and

the Sun-spot disturbance-perihelion,
In order to form an estimate of the extent, to which circumstances
favoring the generation or disturbance of ethereal waves affect the amount
of spotted surface, I would suggest a preliminary examination of ob-
servations with especial reference to the following planetary configura-
tions :

planets in heliocentric opposition : ¢. y., near the opposition of Mercury
and Venus, especially if Mercury is about 60° from perihelion ; of Venus

eee Saturn is near aphelion ; of Saturn and Uranus.

centre of oscillation of the longer radius vector : ¢. g., near the conjune-
tion of the Earth and Mars; of Mars and Mercury, if Mars is near peri-

3. When one of two planets in heliocentric conjunction is near a centre.
of explosive oscillation (3): @. g., near the conjunction of Mercury and

(Read before the American Philosophical Society, July 19, 1872.))
In any explosive or other analogous action along a given diameter,
cardinal points occur at } radius and § radius (—the distance from

radial terminus to a centre of*explosive oscillation), at 4 and 3 (=dis-
tance to a centre of linear oscillation), at } (distance to linear centre
of gravity), and at 4 and % (distance to a centre of reverse or direct ex-
plosive oscillation). The various possible combinations of these numbers
favor phyllotactic and other systematic arrangements to such a degree,
that the very wealth of planetary illustration becomes burdensome and
perplexing, and the attempt to trace the development of our cosmical
system to simple laws seems almost hopeless.
If the primitive disturbance is accompanied (as it must almost neces-
sarily be), by rotation, the ratio 1 : 9 assumes special importance, inas-
much as it represents the proportionate distance of the centre of rotation
from the rotating centre of explosive oscillation. Assuming 7—Sun’s
radius, as our fundamental unit, we are at present unable to determine
whether there is any permanent limit at 9r, that point being within the
sphere of solar atmospheric retardation ; but I have shown in my com~-
munication of March 1, 1872, that there are important divisions,

The lengths and breadths given are a little below the truth, owing to
the loss of the exceedingly thin margin.
Turning to the endo-skeleton, the vertebra deserve mention. There are
more or less complete examples of five of these : in two, both centrum
and neural arch ; in two, neural arch ; and in one, centrum, are preserved.
These have been recognized chiefly by their neural arches, which are sep-
arate. They are in form something like an X, the extremities of the
limbs carrying the zygapophysal surfaces. The only point of contact
with the centrum is a wide process which stands beneath the anterior
zygapophysis, and spreads out foot-like obliquely forwards and outwards,
to beyond the line of its anterior margin. Its surface extends nowhere
posterior to the surface of zygapophysis above it, but a little further
inwards. Its outer margin rises ridge-like to the under side of the neural
arch, and each one forming a semi-circle forms the boundary of the neu-
ral canal, and turning outwards forms the inner boundary of the posterior
or down-looking zygapophyses. The space between these apophyses is
roofed over, so as to produce a shallow zygantrum, which, however, only
seems to roof over the deep emargination of the neural arch of the verte-
bra immediately following. The anterior zygapophyses are often broken
away, so that the neurapophysial supports look like the missing pair,
when the difficulty ensues that both pairs look downwards. The top of
the neural arch is in two cases broad and flat ; in two others there is an
obtuse keel.
The centra apart from theix arches are puzzling bodies, especially since

: inthe present case they are somewhat flattened by pressure. They differ
materially in size, one of them being twice the size of the others. The 4
smaller ones are of the ball and socket type and have a deep longitudinal
groove on each side. The thicker portion of the centrum forms the in-
ferior boundary of this pit-groove, while a thinner portion, possibly a dia-
pophysis limits it above. It is, however, thin, and had no great length.
There is no sign of chevron bones and articulations, so that these verte-
bree may have been cervical. Their bodies are, however, shorter and oy
wider than in those vertebre of any known tortoise. A groove on the
upper surface represents the neural canal ; while a flat portion on each side
i in front, supports the neurapophyses. The large centrum exhibits the
i superior groove, and antero-lateral platform for support of the neural
arch. One end is eupped obliquely, while the other is nearly plane, with

the same obliquity and a slightly raised margin. Its outlixe is sub-tri-
| angular. The lower side of this centrum possesses a short keel posteriorly.
The sides exhibit no pit, but have a thin edge, which is concaye behind
the middle, and then turn outwards. I can see no articulation for a rib.

imally some distance beyond the head. The superior plane of this expan-
sion is continuous with that of the rib, and is flat ; the head of the rib
therefore turns downwards and inwards from it, to join the vertebra.
Now the extent of the inner part of the lamina is such that, were the
head articulated to any of the centra discovered, the former would inter-
fere or overlap. They may, therefore, have been articulated to diapophy-
ses. The expansions are serrato-digitate on the margins, and exhibit |

The weight of the washed ore when dry is one and a half (13) tons to
the cubic yard. The weight of the lump ore is about 1; tons to the cubic
yard. One car-load of 44,919 cubic inches measurement, thoroughly dried
wash ore, weighed 3,042 Ibs. One cubic yard = 46,656 inches. The lump
ore of one car weighed 2,570 Ibs.
Very little flux is required by the Furnace, and this is obtained from
bold outcrops of blue limestone on the State Road two-thirds of a mile
north of the ferry. There is so much lime in the wash. ore and in the clay
of the ball ore, and so heavy a charge of manganese in the ore deposit
that the fluxing of the stock scarcely adds to the expense of its smelting.
The cinder is excellent and the waste of iron is evidently small.
Avound the inside lining of the tunnel head for about four feet down
from the lip of the filling-hole, there forms a coating of concentric layers
of a very solid and heavy substance, consisting chiefly of metallic zine, in
alloy with metallic lead and a small quantity of metallic iron.*
The upper and more solid blue and white limestones of Bompas Cove,
exposed along the banks of the creek, opposite the old furnace site, con-
tain a good deal of disseminated galena. This is decomposed into car-
bonate of lead, filling crevices which have been followed down by shafting
operations during the late war. The two ores of lead were taken in cars,
on a tram road a few hundred yards long, down the creek to a lead mill
erected by General Jackson, and there smelted for the use of the Confed-
erate army. The works are now abandoned, and the shafts filled with
trash or water.
Brown hematite iron ore deposits have also resulted from the decompo-
sition of the limestone beds over the lead-bearing strata.
Greasy Cove is a district of limestone similar to, but much more exten-
sive than Bompas Cove, and carries the same brown hematite iron ore de-
posits of probably equal size. The hills overlooking the flat land of this
cove on the northwest and within half a mile of the river, are red with ore.

These details are not only interesting in themselves, but necessary for
familiarizing the observer with the scene of a geological action, common
enough in our Appalachian region, but rarely exhibiting itself in so bold
and telling a way as at Embreeville.
A fault—an upthrow and overshove—a collapsed synclinal at the edge
of the thrown-down mass—all this is presented to the eye of the struc-
tural geologist, as he stands on the steps of the little Church of Embree-
ville and looks across the river eastward. Hundreds of feet of limestone
outcrop, in part natural cliffs, in part quarry work, demonstrate the
problem of Cambrian overlying Silurian—the Quebee Group overriding
Trenton Limestone—by drawing it in a grandly visible diagram, a mile
long, by 800 feet high.
The solid plates of limestone are bent round in the synclinal without
fracture (other than at the great cleavage planes) as though they had
been as plastic as wax. A slight anticlinal roll immediately precedes the
sudden upturn to a vertical followed by a declining angle in the reversed
sense. ‘I'he exact place of the fault is obscured by a general crush and
sheet-covering of the finely broken shale and very thin bedded shaly
sandstone layers which make the rest of the mountain mass.
Up through these sandy shales, dividing them into an upper and lower
system, rise the bold outcrops of two conglomerate beds, each about 20
feet thick. One of them, forming the crest of the mountain east of the
river, descends in a dyke to the water, sinks under the valley, and reap-
pears to face the slopes at the bend at the mouth of Bompas Creek. The
other forms a dyke along the foot of the mountain from the Furnace
southwest to Bompass Cove. These two coarse sandrocks or finely brec-
ciated conglomerates are shown in the diagram at the foot of the map on
page 445, above.
It will be noticed that another set of sandrocks, not at all conglome-
rate, but semi-crystalline in texture, and (with alternations of softer
kinds, and shale bands) at least 100 feet thick, come in above and (being
nearly horizontal) cause that hog-back topography seen in the horseshoe
bend of the river. It willbe noticed also that above these last sandrocks,
lies a third or uppermost system of sandy shales. These constitute (with
some still higher intercalated massive sandrocks) the bulk of the inwall-
ing river hills (600-800 feet high) all the way up (about 8 miles) to the en-
trance into Grassy Cove; that is, to the next parallel fault throwing
down the Silurians.
It will be evident to those familiar with this characteristic structure of
East Tennessee and Southwest Virginia, that the Nolichnckee River ex-
poses a nearly transverse cross-section of a long prism of earth-crust com-
posed of sandy shales, sandrocks and conglomerates, at least 600 feet
thick, elevated between enclosing sunken countries of Lower Silurian
Limestone.
There is no sign of squeeze and distortion along the southern (G reasy
Cove) fissure, for the uplifted upper shales abut there horizontally against

the down-thrown limestone prism to the south of it. Whereas in the
Embreeville (or northern) fault, the lower part of the shale prism has
been lifted and thrust violently against the limestone prism to the north,
so as not only to override it, but to curl up the ends of its beds into a col-
lapsed synclinal. The force has therefore come from the south, and acts
northward, or north-northwestward. This is not only in accordance with
the law of anticlinal structure, made out in Pennsylvania by the survey
under Prof. H. D. Rogers, 35 years ago, but with nine-tenths of the fault
exhibitions in Virginia aifd Tennessee.*
What the rock system is, a prism of which has thus been upheaved be-
tween the two Lower Silurian districts of Jonesborough to the North,
and Greasy Cove to the South, is still a subject for discussion. Mr. Saf-
ford, State Geologist of Tennessee, gives it the name of Chilhowee, with-
out identifying it closely with any of the great Formations of the
Northern States. It probably underlies immediately the Lower Silurian
Limestones.
One thing is remarkable: its apparent total lack of iron ore and
limestone. There is no appearance of metamorphism throughout the
6,000 feet of rock trenched by the Nolichuckee.
The cross-fault of Bompas Cove, on the west side of which the L. Silu-
rian Limestones are dropped to water level in an almost undisturbed
(horizontal) condition, is, perhaps, the most interesting feature of the dy-
namic scene I am trying to portray; but it must remain for some geologist
to study who has more time at his command than I had, in my hurried
visit to Embreeville. Y,
These cross-faults are incidentally mentioned by Mr. Safford, on page
200 of his Report of the Geology of Tennessee for 1869, when he says:
«484, At the ends of these mountains, the sandstones which form them
are suddenly and curiously cut off, and wholly disappear. The moun-
tains and their rocks, of course, lie generally immediately on the south-
east side of a fault. The sandstones, broken in wide blades, appear to
have been thrust up endwise to the northwest, through the overlying
formations. ‘The displacement is, in some cases, very great. In the case
of Chilhowee Mountain (see section page 190), the sandstones, or, rather,
Ocoee conglomerates, have been brought up and abutted against Carbon-
iferous Limestone.”
The expressions used in the above description are calculated to obscure
the picture to the eye of the reader. The sandstones are prominent
objects in the landscape ; but they are integral and very subordinate
items in the mass of the upthrown (and often but slightly tilled) prism of
earth-crust. To a depth unknown to the observer, the earth-crust in all
this region of Virginia and Tennessee has been cracked along straight,
parallel lines of great length (some of them a hundred miles), but of no

great width, seldom over five miles, In Mr, Safford’s Section (page 190),
across Eastern Tennessee, from the carboniferous table-land, southeast-
ward to the Metamorphic Azoic Mountains of the North Carolina line,
52 miles, there are eight of these faults noted, making the average width
of each prism (supposing no fault has been omitted) 6} miles.
The upthrow or override of the side face of each prism against the
prism to the northwest of it, varies from fifteen thousand (15,000) feet (as
in the Chilhowee Mountain Fault above cited, and in the Montgomery
and Wythe County Faults of Virginia) down to five thousand, as in the
case of the Embreeville Fault, and others of alike kind, in the same
range, where the bottom measures of the Chilhowee, or top measures of
the Ocoee, Formations abut against the Trenton Limestones.
The tilt of a prism, five miles wide to an elevation of only one mile on
its northwest border, gives an average dip of 1 in 5, or 10°. But the tilt
has been produced by a thrust from the southeast, violent enough not
only to produce the tilt, and thrust the prism forward and upward, but to
rub up the broken edges of the layers of the down-tilted next prism, and
to rub down the broken edges of its own layers ; and, moreover, to bend
the whole body of the prism along its northwestern limit. Consequently
we have there dips of 45°, whereas the dips everywhere else (with trifling
exceptions) are scarcely more than 5°.
It may be said, therefore, if astonishment be expressed at the vastness
of these upthrows, considering the weight of the prism, that, in fact,
there has not been so much ipward movement after all.
On the other hand, in the sections J have made across sets of these
faults, in other parts of the region, and where the uptilt is of lower Si-
lurian Limestone against Coal Measures, repeated again and again, the
proportion of horizontal to vertical is as 5 miles to 3 miles, and a dip of
30° pervades the entire body of the prism, and of each prism, from side
to side.
This is a very astonishing state of things. And it characterizes a re-
gion of country fifty miles wide by five hundred miles long, roughly
stated. 2
What supports these long untilted prisms of earth-crust ?
We cannot imagine an underground Pre-silurian topography arranged
with such regularity, as to allow the settlement of the sections of Pale-
ozoic series, in straight lines, hundreds of miles long, and always on one
side, the southeastern.
It seems to me evidently necessary to assume a (in some sense) plastic
underground, on which these wonderfully regular prismatic rods of Pale-
ozoic rock have been able to roll one-third over and adjust themselves.
The alternative must be, that the vacancies (of triangular section)
have been filled with the debris of the lower crushed edges and bottoms
of the prisms,—a most unsatisfactory suggestion—especially unsatisfac-
tory, because the regular over-roll of all the prisms in one direction
.

proves that the laterally acting energy (whatever may have been its origin)
was acting ona great plate of Paleozoic rockmass, at least (counting in
the coal measures) fowr miles thick ; solid, although flexible, itself ; but
free, when broken, to slide on its foundations, as the broken up flakes of
ice slides over the water which supports them.
That there was no absolutely fluid (lava?) underground beneath them
is evident from the total absence of volcanic rocks at the present eroded
surface, along these faults, even when the uppermost Sudsilurian rocks
appear in one wall. (The numerous warm springs connected with the
Virginia faults are explicable on chemical principles, no doubt.) But be-
neath the uppermost Subsilurians are vast formations, all more or less
metamorphosed, and many converted into granites and other crystalline
forms. Here we have the plastic mass we need, over the surface of which
(of course, an eroded surface, but, probably, eroded to a plane containing
no Alpine or even Subalpine inequalities) the Paleozoic deposits, consoli-
dated by time into a consistent, but never yet dried, sheet, seven miles
thick in Pennsylvania, five miles thick in Virginia, three miles thick in
Tennessee, moved with a certain freedom, under a lateral pressure, from
the southeast, at the close of the Coal Era.
I have formerly taken occasion to ascribe the difference of effect ex-
hibited by this pressure in Pennsylvania and in Tennessee to the differ-
ence in the thickness of the Paleozoic mass. In Pennsylvania it was
folded ; in Tennessee dislocated. But the difficulty which pressed on
Mr. Rogers to explain the sustentation of the vaults of our Northern an-
ticlinals, is encountered equally by the Southern geologist who will explain
the stable equilibrium of his tilted prisms.
To return from this digression to the cross fissures, which cut off the ends
of the Chilhowee and other mountains (and an example of them is given
in my map of Bompas Cove), it must be understood that they do not obey
one law, as do the principal and parallel dislocations of the country.
They sometimes run square across from one of these to or towards
another ; seldom cutting a prism entirely off; usually cracking its north
western edge fora certain distance into its body. It is a subordinate and
secondary system of faults. But by means of it most of the Appalachian
ridges or mountains, of Middle Silurian and Upper Divonian age, are
swallowed up and ended at the surface ; just as are the mountains of
Chilhowee sandstones, in such cases as that described by Mr. Safford above.
The section accompanying my map will, perhaps, be compared by some
reader of this paper with Mr. Safford’s section on page 202, and they will
be seen to be very different. It is only needful to explain that my section
was made with instruments on the ground under favorable circumstances,
and carefully drawn to the same horizontal and vertical seale ; whereas
the section on page 202 is like Mr. Safford’s other sections, drawn to a ver-
tical scale at least twenty times greater than the horizontal, and, as he
says, ‘‘it is not intended to be accurate in detail.’’
In fact nothing can be more erroneous than the impression on the mind

facts, but bars the way to a right understanding of the structure not
only of this locality at Embreeville Gap, but of similar localities along
the Unaka Mountain range.* There are no such synclinals as are there
represented. There is nothing which in the remotest sense resembles the

Every student of American geology must acknowledge his great in-
debtedness to the assiduous and judicious State Geologist of Tennessee,
who has done so much to elucidate one of the most interesting regions
of the United States. Among the many valuable columns of thicknesses
which he has published, the following (in § 489) justifies the statement I

Embreeyville. It represents the Chilhowee Group, in Doe River Gap,
Carter County.

It is impossible not to see the significance of the immense develop- |
ment of sandrocks and pebble rocks, in the Ocoee and Chilhowee systems,
underlying the Lower Silurian Dolomites, and hugging the flank of the
backbone of the Continent, for a thousand miles through Virginia, North |
Carolina, Tennessee and Georgia, as in New Jersey and New York. It
is a shore deposit on an immense scale, in a shallow sea, with a steeply
inclined margin, and an Alpine range inland. No glaciers ; for the con-
glomerates consist of rolled shingle stones; but torrents, innumerable
and vehement. No large rivers ; for no delta deposits of any size are
apparent. A rapid degradation of the mountains was followed or stopped i
by a partial submergence, which deepened the sea, made the sand deposits |
finer, and permitted the deposit of the Lower Silurian limestones.
The reason therefore why the massive Quebec Group (Potsdam, Chil-
howee and Ocoee) formation does not come up to daylight in the faults |
which break the middle and northwestern parts of the floor of the region
under discussion, is because it thins away rapidly seaward, that is, west-
ward, towards the Coal Area. And in this it only sets an example after-
wards followed by the sandstone and conglomerate members of the great '
Paleozoic system : Nos. IV, [X, X, and XII the Millstone Grit.

DESCRIPTIONS OF SOME NEW VERTEBRATA FROM THE
BRIDGER GROUP OF THE EOCENE,
By E. D. Cops.
(Read before the American Philosophical Society, August 15, 1872.)
MESONYX OBTUSIDENS, Cope.
Represented by a large part of the skeleton of an individual of about
the size of the wolf (Canis lupus). The lumbar vertebra display the
short acuminate, and anteriorly directed diapophyses, characteristic of
carnivora, while the astragalus resembles that of the same group. The
claws are flat and not curved. The molar teeth exhibit two principal
lobes and a thin rudimental at one extremity. The middle lobe isa com-
pressed cone, the posterior, a cutting edge, but medially placed, and less
acute than in Hyenodon, and the sectorial teeth of other carnivora, form-
ing a less specialized cutting apparatus. The canines are well developed.
A premolar is stout conic, with rudimental tubercle at base.

TRIACODON ACULEATUS. Cope.
Established on two teeth of the molar and premolar series. The molar
is subtriangular at the base of the crown, one side being convex ; the op-
posite angle nearly right, and the two remaining sides flat. The crown
is divided into three elevated trihedral cones, one at each angle. Their
adjacent angles are acute, and the angle of union is fissured, like the same
point in the sectorial tooth of a carnivora. The smaller lobes are of equal |
elevation, but the crown of one is expanded so as to be slightly spade-
shaped. The enamel is smooth.

The premolar is smaller, with shorter cusps, and one of the laterals re-

This species is near the 7. fallax of Marsh, but the tooth he describes
is narrower in proportion to its length, and has the anterior lobe little
over half as high.

Hyorsopus pyemaus. Cope.
represented by a portion of the right mandibular ramus with the
penultimate and ante-penultimate molars in perfect preservation. These
teeth present four cusps, of which the inner are crescentoid in section,
the outer conic. They are all elevated, and the outer anterior is in both
teeth compressed and bifid ; it receives an oblique ridge from the inner
posterior. Enamel smooth.

This is a small species of the genus, being about equal to the Hyopso-
dus paulus L. The penultimate molar in the allied species, Lophio-
therium ballardii, Marsh, measures 3.2 lines in length.
ANOSTIRA TRIONYCHOIDES. Cope.
This species is about the size of our existing Chrysemys picta. It dif-
fers from the A. ornata, Leidy, in various respects. Thus the sculpture
of the costal bones is pit-like, as in some species of 7réonya, instead of
striate-ridged. There is no keel on the pygal bone behind. The first
marginal bone is longer, and does not exhibit the prominent shoulder
seen in A. ornata. he marginal bones are not unlike those of that
species, having central small tubercles, and radiating ridges. The species
is not uncommon in the Bridger beds on Cottonwood Creek, Wyoming.
ANOSTIRA GEDEMIA, Cope.
This species is nearly twice the size of the last. It is distinguished by
its peculiar ornamentation, This consists of bosses or swollen portions
of an oval shape, which stand transversely to the long axis of the body,
from a quarter to a half an inch apart. They sometimes form short
ridges, surface otherwise smooth. Locality same as the last spogies.
ANOSTIRA MOLOPINA. Cope.
This species is intermediate in size between the two last described.
It is distinguished from both by its ornamentation. This consists of a
delicate and rather scattered impressed punctation, on the costal bones.
Across this extend oblique ribs extending in a diagonal direction out-
ward near the extremities of the costals. The width of one of the cos-
tals is M. .023. The costals in this species display no suture for the mar-
ginals, and the extremity of the rib projects a very little.
TRIONYX CONCENTRICUS. Cope.
This species is not uncommon in the Bridger sandstone. It is well
characterized by its sculpture, which is coarsely and distinctly pitted.
Across the costal bones run parallel ribs, which enclose between them
from three to one row of pits.

TRIONYX THOMASII. Cope.
This tortoise is again distinguished from all those known by its sculp-
ture, this being very delicate and obscure when compared with the thick-
ness of the carapace. It consists of small tubercles of more or less elon-
gate form, which may or may not inosculate ; eight may be counted in

World, Baldwin’s Gazetteer, and other important works.
Found with the Z. concentrica, on Cottonwood Creek, Wyoming.
AXESTUS BYSsINUS. Cope
tenus et species nove Trionychidarum.
This genus is represented by a species which is allied to Zrionyz, but
which differs in some important respects. The sternal bones are pro-
vided with an enamel stratum exterior to the usual dense layer of the
bone, which is not sculptured. The post-abdominal bone has no sutural
connections, but sends out tooth-like processes at its angles. The caudal
vertebre are procolian, furnished with stout diapophyses and not very
elongate ; ball depressed, undivided. The cervical vertebree are elongate
and relatively very large. The claws are very large, and one at least flat
and straight; the phalanges have broad trochlear surfaces, which indi-
cate a moderate amount only of vertical movement. Both humerus and
femur are curved and with extensive trochanters. The procoracoid and
scapula are of equal lengths and the coracoid is much dilated distally.
Char. specif. The portions of plastron preserved are thin for the size
of the animal, and all the bones are especially dense and smooth. The
(2) post-abdominal has the free margins acute and serrulate. There is an
(2) external gently convex edge with a long process extending backwards;
and one long narrow one inwards. The enamel is white and is marked
with decussating lines of osseous deposit, as in woven linen. This is not
the result of wearing. The cervical vertebra is without spine ; it is com-
pressed in the middle and is without any pneumatic foramen.

BAENA HEBRAICA. Cope.
Established on a large and nearly complete fossilized tortoise, which
lacks the posterior lobe of the plastron, and a corresponding part of the
carapace. The component elements are codssified.
The costal seuta are very wide, excepting the first pair, whose posterior
margin is sigmoidally flexed. The anterior vertebral is concave behind,
and has convex lateral margins. The marginal scuta in front are very
narrow, but the fourth on each side is suddenly widened in front to meet
the suture between the first and second costal scuta. The sutures are all
perfectly regular. There are only four inframarginal scuta, of which the
t, forming, with the third, an angle project-
second from front is the large
ing inwards.
The carapace and plastron are smooth, excepting in the lines of the
sutures of the costal bones. In this position-there is, in each case, a series
of short pit-like grooves parallel to each other, and transverse to the axis
of the bone, forming figures like some Hebrew letters, the Greek //, etc.
The borders of the carapace are obtuse, and the general form is almost
round. The diameter is almost eighteen inches.
This species may only be compared with the B. wndata, Leidy, with
which it agrees in having the humeral scuta crowded to the front of the
plastron, and haying a common centre with the gulars, which they little
exceed in size. It differs in having four instead of five inframarginals,
regular sutures, a differently formed first costal, wider lateral marginals,
| and in the smooth carapace with the peculiar sculpture mentioned.
TESTUDO HADRIANA. Cope. Spec. nov.
Indicated by two individuals, one nearly perfect, the other chiefly rep-
resented by a complete plastron.
This proves the existence of a very massive species of the terrestrial
genus Testudo. The plastron presents a short wide lip in front, which is
turned outwards, forming a strong angle with the plane of the upturned
front of the lobe. This lobe is bordered by a thickening of the upper
surface, which cuts off the basin from the lip, as a high ridge. The pos-
terior lobe is deeply bifureate, each post-abdominal projecting as a trian-
gle. There is a notch at the outer angle of the femoral scute. The
\ hyposternal bone is ereatly thickened within the margin above, and an
elevated ridge bounds the basin of the plastron behind, as before. The
middle of the plastron is thin.
The carapace is without marked keel or serrations. It is remarkable
for its expanded and truncate anterior outline, which is nearly straight
between two lateral obtuse angles.
Length carapace, M. .750 = 29 inches; width, .630.
The marginal scuta are narrow, and there is a large nuchal plate.
Same locality as the last.
PALAOTHECA POLYCYPHA. Cope.
This genus and species of tortoises are indicated by vertebral, costal

and marginal bones of very small individuals. These bones are, how-
ever, not only thoroughly ossified, but are very stout, indicating tlie adult
age of the animal. The deeply impressed scutal sutures and heavy pro-
portions, as well as the elevated carina of the carapace, indicate affinity
with Cistudo, or perhaps, Testudo. As another generic character, it may be
noted that the vertebral bones are subquadrate, and support the neural
canal without intervening lamina.
The carina of the carapace is abruptly interrupted occasionally ; some-
times with, sometimes without, a pair of pits, one on each ade. The
marginal bones are well recurved, and the scutal sutures are deeply im-
pressed on them.

PALMOTHECA TERRESTRIS. Cope.
Represented by three individuals, one of which may be regarded as the
type. They are all thinner than the P: polycypha, and larger, being
about equal to the Aromochelys odoratus of our ponds.
In the type specimen the carina of the vertebral bones is interrupted
by a deep sutural groove, which is less pit-like than in P. polyeypha.
The bone itself is broader than long, being, perhaps, from the hinder
part of the carapace. The clavicular (episternal) bone is preserved. It
is characterized by the considerable and abrupt projection of that part
enclosed by the gular scutum, which resembles what is sometimes seen
in Testudo. The edge of this part is entire and aeute. The posterior
part of the projection forms a step-like prominence behind, on the supe-
rior or inner face. The bone is almost as wide as long, and the mesos-
ternal causes a very slight median truncation, but overlapped much on
the inner side. The gular dermal suture does not reach it.

In a second specimen, a strong groove is seen to bound the lip of the
front lobe of the plastron as in the species of Motomorpha. In it the
marginal is seen to be stout, a little recurved, and sharp-edged, A ver-
tebral differs from those described in being longer than wide.
In a third individual the gular lip is not so prominent as in the type,
and the mesosternal bone truncates the clavicular extensively giving it
thus a more elongate form. The gular scuta expands to its front margin.
The marginal bone is stout and sharp edged, and is not so deeply im-
pressed by the dermal suture, ax in P. polycypha.

NAOCEPHALUS PORRECTUS. Cope.
Gen. et. sp. nov: Lacertiliarum.
Established on an incomplete cranium, with vertebrae found associated.
No teeth are preserved, nor any part of the mandible. The remaining
portions of the cranium are, however, highly characteristic.
The occipital descends posteriorly, and bears a pair of lateral ridges,
which converge rapidly posteriorly. This bone is united with the pari-
etal by suture, which is transverse ; its outline is rectangular, so as
almost to reach the frontals, which are prolonged backwards on each
side the parietal, leaving but a narrow exposure of the posterior processes “
the parietal. These extend backward, and are broken off in the spec
men, but they probably formed parts of arches. The parietal is single,
and there is no parietal fontanelle. The bone is triangular in outline
with the apex anterior, dividing the frontals. These are contracted at
the orbits, and have a projecting superciliary head ; anteriorly they are
thickened. The postfrontals are of remarkable form. They are mas-
sive, and compressed from before backwards; they rise considerably
above the level of the front, and bear on their summits a cotyloid cavity,
which is transverse to the axis of the cranium ; the use of this projection
is obscure. There isan exoccipital foramen, and a large one in the poste-
rior part of the frontal opposite the postfrontal elevation.
The sphenoid is a compressed keel-shaped bone, rounded below, and
with broad alee along much of its length. The occipital condyle is sub-
cordate depressed in outline, with a vertical obtuse angle in the middle
and the sides somewhat plane.
A dorsal vertebra preserved has a single vertical capitular process, and
a short hypapophysis. The neural canal is large, and the neurapophyses
are attached by sutures. The cup is nearly round, very slightly trans-
verse, and in vertical plane.
The cranium is smooth above, except the anterior part of the frontals,
which are finely rugose.
This genus is more or less allied to the Thecoglossa, but better material
will be requisite to decide the question of affinities fully.

Coal beds are opened up and down Tom’s Creek and its branches.
One coal bed, from 5 to 6 feet thick, runs through the bases of all the

use in the guiches back of Guest’s Station (an old log fort, now a store
and, although half a mile from the mouth of Tom’s Creek, overflowed
whenever Guest River is in high freshet), and by Mr. Jessee, and for
several miles still higher up Tom’s Creek. It is mined up Little Tom’s

Coal Basins of the Susquehanna West Branch and the Conemaugh. I
saw no other beds here; but there must be others both below it and
above it; for the beforementioned two-foot bed ought to be above it, as
the above section (2) shows.
I made a measured section of one of these hills, called Robert’s Butt
(over 700 feet high, and capped with a fragment of the great conglom-
erate sandrock which once covered all the country), as a specimen of the
barriers which separate all these streams from one another, in the coal
field, and to show how impracticable any railroad line must be which
does not follow closely the great water-courses.
The following section up the side of Robert’s Butt, half a mile north
of Guest’s Station, was made with an aneroid barometer. It shows the

The bed is here, really, but 2} to 3 feet thick. It is covered with a
plate of sandstone which is several feet thick ; and, although the pres-
sure produced by the Great Downthrow, which runs along at a distance
of about half a mile due south of the locality of the mine, has folded the
coal bed with the sandrock back upon itself, yet the sandstone of the
rock, thus caught in between the walls of the fold of the coal, is perfectly
solid and does not show the slightest trace of disturbance. This is a
striking, but well-known phenomenon. The coal itself is bent round,
and shows sharp tongues, in the fold.

Here, also, the bed, which when doubled measures 5 or 6 feet thick,
is really but a three-foot bed. There is nothing, in fact, to identify it
with the ‘‘Six-foot’’ coal of Wise County. But it may very well be the

It is opened again at (¢) some hundred yards higher up the creek, and

The top and bottom benches good, the middle bench bony. Over it are
three or four feet of slates, and then comes a one-foot bed of bony coal.
The report goes that the miners found these two coal beds close together,
down. below ; making thus one very fair fowr-foot coal bed. A diagram

All this is not very encouraging for the coal trade. But the same bed

the coal lies flat in the water; and several pits, sunk through it, are
deeper than the height of aman. The bed must be nearly, or quite, six
feet, and yields good coal (as indeed it does at the other openings); but
what its constitution may be I do not know. It is probably subdivided
into benches of different qualities ; and, no doubt, has some of the slate
of the above last section running through it. Its position on the anticli-
nal will make mining difficult.

Measures there come up to the Downthrow in a flat and undisturbed con-
dition ; and the dying down of the crown of the anticlinal in the Six-foot
bed so rapidly that the bed lies flat in the creek only a few hundred
yards above where it plunges at angles of 40°, 50° and 60° proves the
same thing.
throughout the body of Stony Ridge makes the whole disturbance of con-|
siderable magnitude ; and I have no doubt that when it is well examined
to the eastward, it will be found to run in that direction some miles ; not,
perhaps, as an anticlinal but as a downthrow ; and it may very well be
the Abb’s Valley Downthrow, of which more hereafter.

LAUREL RUN COALS,
Leaving the curious topography of the Big Creek, Middle Creek, and
Mouth of Indian Downthrow to be described hereafter, in connection
with Paint Lick Mountain and its Iron Ore, and going east up Indian
sreek Valley, I can only report coal mines on Laurel Run, a side branch
coming into Indian from the northwest. Mr. Christian has here opened
several beds, one of which is reported to be much over six feet thick.
The coal is wagoned to the county-town of Tazewell, Jeffersonville, fifteen
or seventeen (15 or 17) miles distant. The following sketch will show
how the coal comes out to market—two miles to James Smith’s, on the
3aptist Valley Road (beautifully engineered, at low grades), formerly a
turnpike, and still the highway between East K entucky and Middle Vir-
ginia; two miles to the Clinch Valley Road ; thirteen miles by either of
these two roads to Jeffersonville :

What the character of the Christian Coal is I do not know by personal in--
spection ; but it must come from the same beds, and be essentially similar
to the Scott Coals, and also to the Abb’s Valley Coal next to be described.
Just east of the Christian Mines runs a limestone valley, along the
south side of the Downthrow, in which the waters sink into caverns. Tt
is called ‘Sinking Waters.”? Any one familiar with Abb’s Valley (15
miles further east) will see at once, that the formation is the same ; but
I will show that Stony Ridge separates the two valleys and that the
coal areas which I have been following all the way from Wise County are
cut off, or whittled down to a fine point, opposite Jeffersonville. The next
cross-section, No. 8, will show how this is done, and also how the Abb’s
Valley coal beds are brought down to the present surface by quite a dif-
ferent Downthrow from the one we have been tracing thus far, all the
way from Guest’s River in Wise County ; a Downthrow bchind and to
the north of this one ; as the map in colors will also help to show.
The Clinch Valley Downthrow, going east from Indian Creek, catches
in its jaws a less and less number of beds and width of coal ground, until
at last, on crossing the great road from Jeffersonville north to Tug Fork
of Sandy, it holds but the lowest coal bed, standing at a high angle and
very little of it left.
This is seen on the Section No. 8, marked Captain Frank Peery’s Coal.
How far east along this crack this coal can be traced. I do not know ;
but nothing of value can be expected from it ; which is a great pity ; for
at this point easy access to the back country ends.

To get over into the Abb’s Valley Coal Fields, two mountains must be
crossed, or, rather steep stony hills, consisting of all the formations from
the coal down to the limestone ; especially Sandrocks X. (Catskill) and
IV (Shwangunk) here much diminished in thickness ; which accounts for
the comparative lowness of these mountains when compared with the
high mountains formed by the increased outcrops of these formations in
the Northern States.
The deep rapid rocky bed of Mud Fork of Bluestone lies between the
two mountains and descends eastward. Where the turnpike crosses it
it is 400 feet below the notch in the crest of the first mountain, X (s ¥

Lesley. ] 504 [April 21,
Abb’s Valley is produced by a great upthrow of the Lower Silurian
limestone against the Coal Measures. The turnpike enters it almost at
its head, or western end. From the notch in TV through which the road
passes, to the Dry-water course in the centre of the valley is a descent
(by barometer) of only 110 feet. Westward the valley rapidly fills up,
and that is the course to take in locating a railroad from the mines out to
Jeffersonville. A feasible route may be obtained, I think, by keeping up
Abb’s Valley to and over its divide, and down Cavyitt’s Run to the Clinch,
two miles west of Jeffersonville.
The cause of the heading up of Abb’s Valley and Mud Fork Valley so
suddenly westward, and against what seems to be the main body of the
Tug Fork of Sandy Coal Measures, is a most interesting and important
affair, which should be investigated. I can only conjecture it. I take it
to be likely that the Abb’s Valley Upthrow of limestone starts across the
Measures southwestwardly, becoming less and less of an upthrow, and
thus swallowing down from the surface first, the Lower Silurian lime-
stones of Abb’s Valley, and then the shales and sandstones of the two
stony ridges IV and X; and that it finally merges in the Clinch River
Upthrow. At all events, such a geology would result in a topography of
this sort : The limestone and shale valleys would head up suddenly against
a ridge composed of Coal Measures Conglomerate or Sandrocks,
My advice is, that no coal-freight railroad line be sought for in the
direction taken by the Jefferson and Tug Sandy Turnpike. But, on the
contrary, that a line be sought further west, more down the Clinch, viz. :
up Cavitt’s Creek. Let the coal beds there be carefully explored, and a
line be found across the divides beyond the west line of Abb’s Valley.
ABB’S VALLEY COAL.
Wifty feet below the summit of the hill, shown in the ‘‘Local Map’’
on the next page, and nearly 150 feet above the coal bed at its base, is
a layer of very coarse, gray, friable sandstone, weathering yellow, with-
out pebbles. Over it a tree has turned up a coal crop.
The coal bed below is, perhaps, the only workable bed of this district.
For, after descending, at a slope of one or two (2°) degrees, south 20°
east, through the base of the hill, and getting under water level, it seems
to turn up suddenly and quite vertically, and to outcrop along the bottom
of a little valley. It has been mined a little close to the turnpike (0)
and Mr. Smith reports it to be ‘‘as wide as a room.”’
Ten miles east of this, and in a similar position, a coal bed is mined,
which I judge to be the same one, and it is called ten (10) feet thick.
In the openings at the foot of the hill (at a) it has been merely thrown
out from the water of the little Hy Peegits
dug coal all through this re-
gion, gives its thickness as (5)
five feet of coal in 5? of space.
A dirt bed, four inches thick,
separates the lower bench of
very fine coal from the upper and main body of the bed.

This coal bed is dug into by the farmers, at several places on the hill-
sides of Laurel Fork, from half a mile to several miles north of Smith’s
coal, It is called six feet thick. Cochrane says he has dug it on Laurel
where it was good seven feet.

The level of the coal opening is (by barometer) 115 (one hundred and
fifteen) feet above Smith’s house ; which house is 125 feet below the
summit of turnpike crossing, Stony Ridge (No. IV). [See p. 504.] The
coal and the turnpike summit are, therefore, nearly on a level.
From these coal outcroppings just back of Abb’s Valley the coal field

of West Virginia and Eastern Kentucky extends, without a break, to the
Ohio River. And the south edge of this coal field is the north ridge of
Abb’s Valley. The coal beds can be opened anywhere in the hills, just
north of Abb’s Valley ; and several low windgaps, similar to that at Mr.
Smith’s, give the people of the valley access to the coal field. But, as I
have said before, the railway line which passes through Tazewell must
approach the coal field from the west—not from the south ; around the
head of Abb’s Valley, from Cavitt’s Creek. This will also subserve the
interests of any railway projected from the Ohio River up Tug Fork of
Sandy to Jeffersonville.
(N. B.—I do not feel entire confidence in my geology of the sandstone
ridges at Smith’s,—the ridges which form the north boundary of Abb’s
Valley. They need much more careful study than I could give them.)
THE IRON ORES OF IL AND V.
The valleys of Tazewell and Russell, in Virginia, being geological, as
well as geographical, prolongations of the interior limestone valleys of
Pennsylvania, such as the Nittany, Morrison’s Cove, and Kishicoquilis,
contain necessarily the same kinds of ore, inthe same formations, and inthe
same conditions. I mean that the unbroken ground is at present covered
with patches of brown hematite ‘ blossom,’ just as the ground used to
-be where our charcoal furnaces stand ; and that the color of the road and
field soil is the same as that of our best iron ore banks; the limestone
rocks project in the same style, have the same internal composition, and
exhibit the same corroded and-dissolved surfaces ; and potholes, caverns,
and sitks abound along certain lines of outcrop. All these things are
now known to bear an intimate relationship with both the original setting
free of the mineral iron from the limerocks, and its subsequent deposit
and consolidation. And it seems to be becoming clear to our geologists,
that while there are regularly stratified beds and belts of the ore at two
or three distinct horizons in the Lower Silurian Limestone Formation,
which may be traced for many miles along the strike of the rocks, there
are also vast accumulations of this brown hematite ore along anticlinal
axes, especially wherever these are fractured ; or degenerate into pure up-
throw faults. It stands to reason that such a line of fracture, with a high
wall on one side of it, should, in the course of thousands of ages, have
collected vast quantities of the peroxidized iron which was being, through
all these ages, set free in the slow dissolution of the limestones and the
reduction of the whole mass of upheaved country to its present level. To
say nothing of the facility afforded by such fissures to the decomposing
and recomposing agency of drainage waters.
It is along the great upthrow fissures, then, that we are first to seek the
iron ore deposits of this section of Virginia. And such a spot was
pointed out to me near the mouth of Lick Run, on the hills bordering the
north bank of the Clinch River, in Russell County, at section line No. 4
upon the map. Large masses of ‘blossom ” lie scattered about the
fields.
Similar shows of ore occur in other places. The hills southeast of Jef-
1871. 507 (Lesley.
fersonyi lle, just outside the town, show the existence of ore beneath the
surface. Great quantities are reported two miles east of the town; and
still more abundant exhibitions in the cove of Wolf Creek, behind Buck-
horn Ridge, north of the forks of Wolf Creek, and opposite Rocky Gap.
Immense shows are reported in Wolf Creek Valley, inside of (or south
of) Rocky Gap.
I have myself no doubt of the correctness of these reports, so far as
surface exhibitions are concerned. And it is an old and good iron mas-
ter’s maxim, that where there is plenty of blossom there will be plenty of
good ore. The fact is geologically exact. For the blocks of ore on the
surface of limestone land (like the masses of white quartz on the surface
of a mica slate country) are the undissoluble parts of the original country
left behind by the slow and imperceptible mouldering away and
removal of the softer material.
A downthrow fissure, also, traverses Wolf Creek, at the foot of Clinch
Mountain, as shown in the following continuation of section 8, and this
fissure brings the No. IV sandrock of the mountain (which surrounds
Burke’s Garden) at a dip of 380°, down against the limestone of the val-
ley. How far this fissure extends eastward I do not know ; but certainly
beyond Rocky Gap.

Lesley. ] 512 [April 21,
Captain Smith and his son-in-law Mr. Robinson many years ago sank
a line of shafts across the (tertiary or postertiary) plain on which Salt-
ville stands, and all of them through gypsum all the way down. Others
were sunk by Smith & Robinson, Campbell, Taylor & Bowen, Meik and
others at other places in the Holston Valley for a length of twenty (20)
miles, more orless, and up Cove Creek four or five miles still further east.
No attempts were made to get the plaster further on towards Sharon Alum
Springs; but there is nothing to intimate its non-existence except the
absence of outcrops through the soil, These outcrops naturally exist-
ing, or accidentally exposed in farming, or by the railroad cuttings south
and west of the village, have alone (as it seems) determined the search
after gypsum in the valley. And as the Saltville people alone have any
proper machinery for sending it to market, a stop has been put to all
exploration elsewhere.
Moreoyor, seeing that Capt. Smith struck a copious brine in two of his
wells, the opinion early prevailed that the salt and the gypsum were
geologically connected. This opinion induced a number of persons to
sink in the gypsum outcrops not for gypsum but for salt water. As salt water
_ was obtained in no single instance other than Capt. Smith’s two wells, all
hope of obtaining brine and making salt elsewhere than at Saltville has
been long since abandoned ; and consequently all exploration of the gyp-
sum rocks, which had no commercial value to the salt-well borers.
It is therefore probable that the limestone wall (the south wall) of the
Holston River Downthrow (Upthrow of limestone) will in course of time
be discovered to be converted into gypsum at other points besides those
specified above ; and that the gross quantity of gypsum existing beneath
the surface along this part of the Holston River far exceeds any estimate
which [ can make from the gypsum banks already opened. And for the
same reason it is probable that the limestone walls of the other Upthrows
of the region will be found turned into gypsum, at least in certain places,
and in very considerable abundance.
The appearance of brine in such quantity and of such strength must
be considered as a local phenomenon explainable without reference to the
gypsum. Such an explanation may be found in the very curious lake-
deposit of the little triangular plain of Saltville; a deposit evidently
made in a deep little lake or pond basin filled with red mud saturated
. In this mud the salt-water
ksalt deposit now rises the
with salt-water, gypsum drainings, &c., &
has deposited rocksalt, and from this
copious discharge of brine which furnishes all the supply needful for the
extensive salt works. The salt lies in solid form, mixed and inter-strati-
fied with compact red marl or clay, 200 feet below the water-level of the
Holston ; and the borings..have gone down (at the Salt Works) 176 feet
further without reaching the bottom! On the top of the deposits of salt
and mud is a stratum of blue slate more than 100 feet thick. Over the
blue slate lie 60 or 80 feet of gypseous clays. The limestone country being
cavernous to great depths, and especially along the face of the Down-
throw, it is not surprising to notice that the level of water stands the
same for ali the wells and shafts sunk at Saltville and rises and falls in sym-
1871.7 513 (Lesley.
pathy with the Holston River. This accounts for the inexhaustible supply of
liquid. The heaviest pumping has no perceptible effect in lowering the level.
In 1853 the salt yield was 300,000 bushels; 50 Ibs. to the bushel, and 6 bush-
els to the barrel ; at 50 cents a bushel. Five furnaces were then running
24,000 gallons of brine pumped daily ; 10,000 cords of wood burned yearly.
During the Civil War, four wells were pumped night and day for six
months, and yielded 1,000,000 bushels of salt during that half year.
There were then sixty-nine different ‘‘ blocks of kettles”? going. These
kettles, broken and rusty, lie scattered about the valley for six miles,
half buried in piles of burnt and broken down walls which represent the
various works then in full operation. Some of the salt water was carried
in railway tanks nine miles to Glade Spring Station on the Virginia and
Tennessee Railroad, and boiled there.
At present there are three ‘‘blocks,’’ of 80 kettles each, (5 bushel to a
kettle) per 24 hours, making 360,000 bushels per year, of 800 days.
Preston’s gypsum banks yielded 2000 tons in 1854; the cost at the
mines, in lump, being $3, and in flour $5; eighty miles distant $20.
What the yield has been since and what it is now, I do not know. Ope-
rations are vigorously carried on at four or five shafts. Plaster is now
sold at the mines for $2.50 the ton; at Sharon Alum Springs, 35 miles to
the eastward, at $10, in wagons; and is carried forty miles further east
for use upon the soil. Its virtues are well known and highly prized. It
doubles the grass crop and grain, and greatly improves corn. One bushel
of 100 pounds is sown to the acre.
A railway from Saltville east would find a market for all the plaster it
carried. Plaster would go east to the Wolf Creek Fork Junction, and re-
turn by the other line to be used on the pasture lands of Tazewell and
Russell and Wise Counties. But its greatest commercial outlet would be
towards Staunton and Winchester.
Although the gypsum rocks have not the regularity of a coal bed, and
some difficulties, of a kind peculiar to this district will be encountered
when mining operations are extended to cope with the demands of com-
merce along a great trunk railroad, yet I see no practical limit to the
eapacity of the gypsum belt for exploration. Shafts five and six hun-
dred feet deep have permitted the miners to feel the gypsum masses for
fifty yards in width. Such a mass, limited by such a shaft, weighs six or
seven hundred thousand tons, provided the gypsum be solid the entire
depth of the shaft, &c., &c. This is not the case ; neither, on the other
hand, is the width of the column of gypsum limited to fifty yards, or to
any other figure. Nothing can be more irregular than the masses of gyp-
sum underground—unless it be the course to be taken to get it out to the
surface. In spite of all mining difficulties the value and scarcity of
the mineral in all other parts of the country must make its mining in this
district always extremely profitable, and its railway carriage over long dis-
ances inevitable. It must always be in demand; can always pay a high
freight charge, and cannot meet with competition from the Nova Scotia
plaster until it arrives within a hundred miles or so of tidewater. Westward
and southward it may go five hundred miles without meeting competition.

Prof. Edwin J. Houston called the attention of the Society
to a remarkable instance of the acoustic sensitiveness of
matter. “While visiting a number of water-falls on Adam’s
Brook, Pike Co., Pennsylvania, I noticed one in which a
scanty supply of water was dripping, in thin delicate streams,
from the moss covered walls of a precipice. The day was
unusually calm, and the veins were remarkably free from
ventral segments for a considerable distance from the fila-
ments of moss from which they issued. Struck with this
circumstance the idea occurred to me to test the sensitive-
ness of the stream to sound pulses. J made the attempt, and
after several trials found a note, a shrill falsetto, to which
they would respond.
The experiment was one of extreme beauty. At one point
516 [Sept. 20,
Chase. ]
of the falls, there were no less than one hundred of these
streams, and on sounding the required note the groupings
of the drops and the positions of the ventral segments in-
stantly altered in quite a marvellous manner. This case of
acoustic sensitiveness is one of the most extensive I have
ever noticed.
A. second fall was found that would respond to certain
notes, though it was not equal to the first in sensitiveness.
Though not able, from a sudden flooding of the streams,
to discover the exact conditions for success, I believe the
explanation of the phenomenon to be the same as that now
generally given for sensitive smoke and water jets, viz: that
the sound pulses produce a vibration of the orifice of the jet,
by which the constitution of its issuing stream is altered.
The orifice in the case is replaced by the thin moss filaments,
which are surrounded by the stream instead of surrounding
it. rom their shape and position their filaments, acting as
reeds, readily accept the motion of the sound waves and so
alter the constitution of the vein.”
Prof. Chase communicated observations on Daily Auroral
and Meteoric Means, and on some new correlations of stellar
and Planetary distances.

The meeting was then adjourned.
DAILY AURORAL AND METEORIC MEANS.
By Purny Earur Case.
(Read before the American Philosophical Society, Sept. 20, 1872.)
The apparent influence of meteoric falls upon auroras, which is indi-
cated by the five-day means, (ante p. 402), renders more minute observa-
tions desirable, in order to ascertain to what extent a similar influence
may be traceable in the daily means.
The only available observations that have fallen under my notice,
from which any satisfactory approximation can be made to the daily
meteoric curve, are embodied in Baumhauer’s table of the recurrences of
meteoric stones and fire-balls, quoted by Lovering, (‘‘on the Periodicity
Sa
1872.] 517 [Chase.
of the Aurora Borealis,’’ p. 220). Lovering observes that the days sig-
nalized by the frequency of these phenomena are also days which, accord-
ing to Quetelet, are distinguished by extraordinary numbers of shooting
stars. Ihave grouped the second means of Baumhauer’s numbers in
five-day periods, and calculated the ratio of each ordinate to a mean or-
dinate of 100, in order to justify the following comparison with the auroral
ordinates, which were similarly computed from Lovering’s table. 1

CYCLICAL RAINFALL AT SAN FRANCISCO.
By Purny Ear_e CuAse, PrRoressor oF Puysics In HavERFORD
COLLEGE.
(Read before the American Philosophical Society, July 19th and October
18th, 1872.)
Although I know of no good reason for admitting that the question,
whether the moon exerts an influence upon the weather, is still an open
one, there is, undoubtedly, considerable uncertainty as to the value of any
predictions that may be based upon such influence, liable, as it is, to local,
accidental and variable disturbances, partly of a known and partly of an
unknown character. On this account, I think it desirable to collect and
discuss all accessible records of observations extending over a period of
ten or more years, especially in the neighborhood of sea-coasts and large
bodies of water, in order to find how the lunar weather-curves are modified.
by the forms of continental relief, the average hygrometric condition of
the air, the changes of wind, and other obvious or more obscure sources
of perturbation. I am willing to devote all the time I can spare from

gladly welcome the co-operation of all who may feel an interest in studies
that promise new and satisfactory results as a reward for diligent labor.
The success of the Signal Service Bureau* has demonstrated the im-
portance of careful attention to the most minute indications of possible
law, and the influence of the physical geography of our continent upon
‘the weather has been so well ascertained that we may reisonably hope
for similar success from a like careful study of astronomical influences.
The well-known tendency to weekly metecrological cycles has never been
attributed to any more obvieus or probable cause than lunar modifications
“of solar actien, and such evidences of cyclical uniformity as have already
rewarded my limited researches, encourage me to hope that much of the
apparent discordance and supposed accidental irregularity, by which
meteorologists ave still perplexed, will be finally shown, by broad generali-

* Captain Toynbee’s recent discussion, for the British Meteorological Committee, ‘‘ of the me-
teorology of the part of the Atlantic lying north of 30° N., for the eleven days ending 8th Feb-
ruary, 1870,’’ gives very flattering evidence of the estimation in which this success

zations, to be as completely subject to ascertainable laws as are the mo-
tions of the heavenly bodies.
About a year ago, I showed, by my discussions of the Lisbon rainfall
(ante pp. 178-190), that it is possible, uuder favorable circumstances, to
obtain satisfactory evidence of lunar influence upon the weather, even
from a comparison of the rainfall in different cycles of less than six
years’ average duration. My subsequent discussion of the monthly
means of Tennent’s San Francisco observations (Journal of the Franklin
Institute, lxiii. 204-6), led me to hazard certain predictions relative to the
tidal rains on the opposite shores of continents, and the influence of
opposite winds, or of upper and lower tidal currents. Mr. Tennent has
gcnerously furnished me a copy of his'daily observations on the rainfall,
which so fully corroborate the first and third of those predictions, that I
hope to obtain from him an equally complete record of the direction of
the wind, in order to have the requisite data for similarly testing the
other two. Governor Rawson W. Rawson, C. B., has also kindly con-
sented to provide me with a transcript of observations at Barbados, a sta-
tion within the belt of the trade winds, and, therefore, favorably situated
for such comparisons with the San Francisco observations as may serve

haps, supply additional data of a novel character.
The accompanying tables and curves are constructed on the same plan
as those in my previous meteorological papers. The scale and the degree
of smoothing by successive means are uniform ; the comparative influ-
ence of the sun, moon and Jupiter can, therefore, be readily seen ata
glance. The vertical lines (0 to 7) in each set of diagrams indicate the
mean hour at which the moon or planet is on the meridian, as follows :

The tidal influence, therefore, co-operates with the maximum direct
solar influence, in the atmosphere as a whole, and especially in the
upper currents, at 0 and 4; in the lower atmosphere and with the surface
winds, at 2 and 6. The positions of Newton’s theoretical high tides
(Principia, B.1., Prop. 66, Cor. 20) are at Land 5 ; the low tides at 3 and 7.
My theoretical low barometer is synchronous with Newton’s high tide ;

The moon’s influence is most marked in the heavy rains (a) ; least, in
the frequency of rainfall (y). The principal maximum both in frequency
and amount, is near the time of full moon, when the local atmospheric

ON THE DENTITION OF METALOPHODON.
By Epwarp D. Cope.
' (Read before the American Philosophical Society, September 20, 1872.)
This discovery of a second species allied to Bathmodon, Cope, repre-
sented by more complete remains of dentition than that on which that
genus was originally established (B. radians), renders it possible to en-
large our knowledge of its characters.
It may be premised that the new species may belong to the group
Loxolophodon, and, as its characters differ from those of the large species
Hobasileus cornutus, furcatus and pressicornis, 1 must retain the last
named genus with characters ascribed in my last paper to the former,
and withdraw the species from the former, to which I at that time re-
ferred them. It appears that this name, used first for a section of
?
Bathmodon, was, perhaps, based on mandibular teeth alone, which in
Metalophodon, differ remarkably from the maxillaries. The cranium of the
new species to be described was so decayed as to be irrecoverable, but
the teeth obtained were in place, and in close proximity, so that there
can be no reasonable doubt that they belong to the same animal.
The species differ considerably from the B. radians. 'The most promi-
nent are: first, the failure of the lateral or straight limbs of the
ry

crescent of the tooth-crown to meet at the apex, in the molars proper 5
second, the presence of two lobed premolars only, the three lobed found
n Bathmodon not being represented in any series. The first character
appears to me to be of generic importance, hence the name applied to it
at the head of this article. It may yet prove to be Loxolophodon, as no
generic character distinguishes the inferior molars of the two. It remains
however, to determine whether that name applies to Bathmodon, ora
genus different from it, as the present. In the meantime the new species
may be called Metalophodon armatus. It is as large as the Indian
Rhinoceros, or perhaps larger.
The incisors are well developed, those of the premaxillary subequal in
size. The crown has a convex cutting edge and flat inner face. The
outer face is convex. In some the inner face is more concave, and is
bounded by a cingulum next the root.
The premolars present a single external crescent of acuminate ontline,
and a smaller, more transverse one, within. A cingulum bounds the
crown fore and aft, but is wanting at both base and apex of the trian-
gular base. Inthe more posterior the crescent is more open, and the
crown less transverse.
Tho molars present an increase in transverse extent of the external
crescent, and the interior one is wanting. In the posterior two the
anterior ridge curves round at the apex, but issseparated by a consider-
able interruption from the posterior. The latter is shortened, and
terminates externally in a conic tubercle, which approaches the outer
extremity of the anterior ridge. In the last molar the posterior ridge
is shorter, nearly straight, and terminating in a cone at each extremity.
The canine is damaged, but was of large size, amounting in one or
the other of the jaws to a tusk. The probably superior is compressed,
with acute edges. The inner face gently convex, the outer more strongly
so, with an acute ridge on its anterior convexity, inclosing an open
groove, with the interior cutting edge. This surface of the dentine when
exposed has a transversely wrinkled character, but no trace of engine-
turning in the fractures.
In the mandible, premolar and molar teeth are recognizable; the
character of the incisors remaining uncertain. As usual in ungulates,
they possess a relatively smaller transverse diameter than do the cor-
responding teeth of the maxillary. They change very materially in
form from the front to the terminus of the series, and in connection
with the superior molars, are very instructive as to the genetic connec-
tion of different types of dentition.
The pecularity of the premolars consists in the fact that besides the
single external crescent exhibited by those of the upper jaw, they have
a rudimental second one in the position it should oceupy in correspond-
ing teeth of Palwosyops. The inner border of the crown is convex, and
extends from apex to apex of the crescents. There are no cingula to
these teeth. The rudimental crescent diminishes anteriorly, its angle

becoming first obtuse, and then disappearing. Posteriorly the reverse
process takes place, and proportions increase. But in the last molars
they do not assume the proportions seen in Palwotherium and allied
forms. They increase in the elevation of corresponding ridges of the
crescents, and decrease in the others, so that the resultant form is
nearly like that of Dinothertwm or perhaps Lophiodon. The outer ridge
of one crescent appears as a cingulum, which sinks to the base of the
crown from the apex. This is rudimentalin the genera just mentioned.
The corresponding bounding ridge of the other crescent is reduced to a
rudiment extending diagonally across the valley between the remaining
crests, as is seen in not a few genera of the Eocene.
We have thus an explanation of the heretofore obscure question as to
the origin of the crescent-bearing tooth of the Artiodactyles. From the
two crested type of Tapirus, the two-angled form developes itself by the
growth of the cingulum and diagonal crest just described. This is seen
completed in Palwosyops. The elevation of the ridges and deepening of
the intervening valleys, would result in the ordinary Ruminant type.
The same process increasing transverse crests only, derives the Mastodont
from the Tapiroid form, and the deepening of the valleys of this, again
results in Hlephas.
In comparison with Bathmodon semicinctus, Cope, the crowns of the
premolars are of similar size, but considerably less elevated.
The measurements cannot be given with exactitude, but are approxi-
mately as follows: Superior incisor crown, width. 75 inch; elevation .60
inch. Canine 1.25 inches from apex, inner face .75 inch. Premolar
length. 76, width 1.1 inch. Molar length crown 1.1 inch, width 1.25 inch.
Inferior premolar, length of crown 1 inch, width .75 inch. Posterior mo-
lar, length 1.30 inch, width .9 inch. The crests of the last mentioned are
quite elevated, one more than the other; the lower with a strong cingu-
Jum at the base, which rises to what is homologous with the base of a tri-
angle, or outwards; none on the inner aspect of the base of the crown.
The cingula of the superior molars are only anterior and posterior.
This large ungulate was found in a stratum below those of the Green
River Group of Hayden, or in the lower beds of that series, near Black
Buttes, Wyoming. Obtained by the Geological Survey under direction of
Dr. F. V. Hayden.
In a line of banks or low blufts, immediately below that in which the
Metalophodon was found, dermal scutes of a small crocodilian are abun-
dant. The discovery of the greater part of a cranium of one of these
enables me to point out the existence of a species of Alligator of still
smaller size than the smallest of the Caimans at present inhabiting
South America, This species, which I call ALLIGATOR HETERODON,
possess several peculiarities. The anterior and posterior teeth differ
exceedingly in shape ; the former are flattened, sharp-edged, and slightly
incurved ; the edges not serrate. Those of the premaxillary bone are
subequal in size, while one behind the middle of the maxillary is larger
1872. J 545 [Cope.
than the rest. The posterior teeth have short, very obtuse erowns
with elliptic fore and aft outline. They resemble some forms seen
in Pycnodont fishes, and are closely striate to a line on the apex.
The upper surface of the cranium is pitted, the frontal and parietal bones,
with large, deep, and closely plaeed concavities. The former is per-
fectly plane, and the latter is wide. The squamosal arch is also wide,
and the crotaphite foramina are large and open. The dermalscuta are
very large for the size of the animal, and were net united by suture.
They are keelless, and deeply pitted, with smooth margins.
The vertebral centra found with other specimens are round. The
codéssified neural arches indicate the adult age of the animal.

LUNAR-=CYCLICAL RAINFALL IN THE NORTHERN TEM-
PERATE ZONE,
By Pirny Earue Case,
(Read before the American Philosophical Society, Nov. 1, 1872.)
My discussions of lunar-monthly vainfall, (ante, x., 489, 538 ; xii, 208";
xii., 179, 523,) embracing observations in Europe, Asiaand America, near
eastern and western shores of oceans, in regions of monsoons and return
" trade-winds, near equatorial and polar currents, seem to be sufficiently
varied in their character to justify a first approximation to the normal
curve for the Northern Temperate Zone. The stations are so well dis-
tributed that the influence of local “establishments”? must be, to a great
extent, eliminated, and it seems reasonable to presume that the residuals.
represent, with some degree of accuracy, the precipitation which is occa-
sioned by the lunar modifications of the average atmospheric currents.
I.have given equal weight to the normals for each station, but as the
Toronto observations cover only nine years, and those at Chiswick are of
the same general character as those at Surrey, I give two complete aggre-
gates: A., embracing stations 2 to 6 inclusive, and B., 2 to 8 inclusive ;
and one partial aggregate, C., for all the stations.

the half-month of lunar opposition ; a pretty regular increase of rain
from the first°octant, when the moon is on the meridian at the time of
greatest solar heat, until nearly the fifth octant, when her dircct merid-
ional influence is exerted at the time of morning low barome‘er ; average
fain when that influence is felt at sunset, or at the morning barometric
maximum 3; a principal maximum, near the morning barometric minimum,
and a principal minimum near sunrise, when the nocturnal precipitation
is over; other minima soon after sunset, after the maximum heat of the
day, and after midnight. These features all seem so natural and so sim-
ply explicable, that I am unable to regard them as other than typical.
I regret that Mr. Hennessey’s observations at Mussoorie were commu-
nicated only for the days of quarterly change. They appear to indicate
a curve still more strikingly similar to that of the solar-hourly rainfall,
and the indication is corroborated by their influence on the general aggre-
gates, as shown in Aggregate C.
It would be possible, even with the data now at my command, to form
interesting approximations to the normal lunar curves for each calendar
month, but I prefer to wait for observations from a much larger number
ot stations, before undertaking any more minute calculations than I have
embodied in the accompanying table. Even these normals may be em-
ployed in connection with barometric and thermometric normals in the
study of weather changes ; provided such allowances are made as are
obviously required, for the blending of currents over or near the great
Lakes, the Gulf, and the ocean. Such limited use of them as I-have
already made, has strengthened my conviction that the day is not far
distant when the normal lunar influence will be ranked among the im-
portant elements for calculating the disturbances, and the tendencies
towards equilibrium, which determine all meteorological fluctuations,
and render satisfactory forecasts practicable.

coveries followed, in which Mr. Lyman, Mr. Gabb, Dr. Le
Conte, and other members took part.

Mr. Chase offered for publication in the Proceedings a
first approximation to a curve of Normal Temperature in
the Northern regions of the Continent.
Mr. A. H. Smith described his observations of the Sub-
alpine botany of the North Shore of Lake Superior, in the
Summer of 1871, and of ifs absence in the Lake Nibbegong
region, further north, which he had explored in the Summer
of 1872; this change of flora he was led to ascribe to the
fact that the waters of Lake Superior were much colder
than those of Lake Nibbegong. His collection of mosses
he had placed in the hands of Mr. James for examination.
He described the ascent of the Nibbegong River and the
thousand islands in the lake itself, which has scarcely been
visited by any observers who could report scientific facts.
Mr. Gabb instanced an analogous change of flora from the
coast to the interior of the northern part of Lower Cali-
fornia.
Dr. Le Conte said that he woudl assign a hygro-metric
cause for this difference, and added that a similar difference
was known to exist between the faune of the coast and the
interior as far across as to the banks of the lower Rio
Grande; and that the line of distinction was sharp and
sudden, being drawn along the summit of the coast range
of mountains, a barrier not more than 3000 feet high at the
place to which he referred. It was evident that the wet
winds of the west flank of this barrier and the dry air of
its easteru, which made the change in flora and fauna.
Professor Haldeman introduced the topic of the Rhyme-
law of the Sonnet in European literature. Tle had made
extensive collections of Sonnets and studied their construe-
tion for the purpose of discovering a normal rhyme arrange-
ment. So far from that, he had already tabulated 600 (six
hundred) arrangements of the sonnet with a prospect of
adding to his tables more.
Pending nominations, Nos. 708 to 707 were read.
And the meeting was adjourned.

A Recorp oF FouRTEEN Orn WELLS AT Brapy’s BEND, ARMSTRONG
County, PENNSYLVANIA.
By. J. P., meumy.
(Read before the American Philosophical Society, Phila., Nov, 1st, 1872.)
Having recently requested Mr. Persifor Frazer, Assistant Professor of
Chemistry in the University of Pennsylvania, to examine for new esti-
mates of quantity the coal areas which have escaped erosion, in the
country on the two sides of and closely adjoining the Allegheny River,
at the remarkable ox-bow bend in its course, 70 miles above Pittsburgh
and 60 miles below Oil City ; he brought back with him a MSS. report of
ot the wells bored by the company on the river banks and along the beds
ot the ravines descending to it from the west. We owe this report to the
kindness of Stephen Halbrook, Esq., Superintendent of the Brady’s Bend
Tron Works.
It is needless to recapitulate the history of the oil discoveries, and the
gradual extension of the oil producing districts from Titusville and the
line of Oil Creek eastward to the Tidioute district, southeastward to the
Clarion, westward to French Creek, and southward via Oil City, Franklin,
Parker’s Landing, and Brady’s Bend, to the neighborhood of Butler,
where the last discovery excitement is now raging. ‘It is only necessary
to refer to my report on the geological grounds for believing the middle
Allegheny River districts to be productive oil country, published in the
Proceedings of this Society, in 1865.* In that paper I have sufficiently
described the locale of the wells now to be described. These records may
also be compared with similar records communicated to the Society and
published in its Proceedings of April, 1865.
The ‘‘ Engineers’ Datum’’ of the following table is an assumed level,
one hundred feet lower than a mark made on the Brady’s Bend Iron Com-
pany’s warehouse, on the river bank, showing the extreme height réached
by the great and disastrous freshet of March 17, 1865.

1872] 563 [Lesley.
From the above table, it appears that all the oil-producing wells men-
tioned in it get their supply from one stratum lying in an undisturbed
and horizontal position, varying in their actual depths below a fixed
datum level from 1,118 to 1,066 feet, a difference of only 40 feet. This
difference is due to three causes, viz. :—1. The different depths in the
sil-besring stratum penetrated by the bottom boring of the wells ;
2. The slight inequalities in the upper surface of the stratum ; 3. And
s, both from the northwest and
chiefly, to a general slight dip of the ro
from the southeast, in towards the centre line or axis of the trough or
basin which here crosses the Allegheny River in its northeast-south west
eourse ; and also to a still slighter and almost insensible decline of the
axis of the basin itself southwestward.
The table also confirms what was prover years ago, long before the fact
was acknowledged by oil men, namely, that it makes no difference whethe
a well is started in the valley bottom or on the hill tops, provided it goes
down to the uniform and nearly horizontal oil-bearing sandrock. For
some of these wells have their mouths at elevations more than 300 feet
greater than others. Some on the river bank, and others high up at the
heads of side ravines. The great No. 8 well was commeneed at an eleva-
tion (379—96-—) 283 feet higher than those on the river bank whieh yield
only from one to three barrels a day.
The following table shows the thickness of the third sandroek where it
was passed entirely through :
No. 2.—No sandrock found and no oil.
-Sandrock, 26 feet ; hard fine white sand.
No. 5.—Sandrock, 27 feet ; fine pebbles.
No. 6.—Sandroek, 16 feet ; with slate partings.
No. 7.—Sandrock, 27 feet ; pebbles pretty coarse.
No. 8.—Sandroek, very coarse and open.
No, 9.—Sandroek, pebble very fine and close, very little gas.
No. 10.—Sandrock, 10 feet; pebbles pretty fine, except in one thin
streak.
No. 11.—To sandrock, no oil, but great gas blow, doubtless from a
fissure.
No. 12.—Sandrock, 17 feet, all pebbles ; steady flow of oil.
No. 13.—Sandrock, 18 feet ; coarse open pebbles; and a fair amount of
yas.
No. 14.—Sandrock, 18 feet ; large coarse pebbles ; fair amount of gas.
Other noteworthy facts are as follows :
No. 1 well, on the river bank, one half mile above the rolling mill,
begun March, 1865, finished 1 866.
No. 2 well, at the mouth of Cove Run, May, 1866—June, 1870.
No. 8 well, on the river above the mill, commenced August, 1868—
pumping in September, 1872, 1 barrel a day.
No. 4 well, on the river above the mill, May, 1869—March, 1870. Cost
£10,405. Record of: strata given below.

No. 5 well, on the river above the mill, June, 1869—April, 1870. At
981 feet struck so powerful a gas vein, that the bore-hole was deluged
with water and abandoned for four months. In June, 1871, athree quart
nitro-glycerine torpedo was exploded without increasing the production
of oil. Th pebble rock was almost as fine as sea-sand.
No. 6 well, on Queenstown Run; August, 1870-—April 5, 1871; drilled
with the water cased out; all the previous wells were drilled in water ;
casing commenced at 357 feet ; not much gas.
No. 7 well, on Queenstown Run; August 7, 1870—March 1, 1871; water
eased out at 512 feet ; seme gas at 1,050; commenced pumping about 9
barrels a day, and has produced up to September 7, 1872, 4,183 barrels.
No. 8 well, on Queenstown Run; June 26, 1871—September 22, 1871 -
water cased out; first show of cil September 22, and began to fill up very
slowly. At 12.35 A. M., September 23, struck a vein of gas and oil
which spouted over the top of the derrick, and was fired by the nightlamp
hung in the derrick, burning the rigging down. The spouts occured
every two minutes. At 9 A. m. the fire was extinguished and the oil
began to fill the tank at the rate of 35 barrels an hour, but gradually
calmed down to about 60 barrels a day during the first month, and October
22 ceased to flow. Tubeing and sucker rods were then put in, and she
began te flow again at the rate of 150 barrels a day.
This well has been cleaned out many times to keep her in good rwnning
order. Immediately after any one such cleaning she produces from 70
to 90 barrels a day, and gradually falls off to about 20 to 25, when it is
anderstood that she again needs cleaning. In fifty weeks she has pro-
duced 9,505 barrels. ‘There is not much gas except when flowing.
No. 9 well, on. the river opposite Catfish; June 24, 1871—October 24,
1871; water cased out; cost $5,750.
No. 10 well, on Lower Campbell Traet; July 10, 1871—May 22, 1872;
water cased out. After passing through third sand at 1,300 feet, put in
a 4 quart torpedo, which seemed to have very little effect. Sand pumped
for two days afterwards and found that she filled up with less than a bar.
rel of oil per day, and therefore concluded it was useless to tube her.
Not much gas at any time.
No. 11 well, on river haif mile below the mill; August 24, 1871—June
24, 1872 ; water cased out at 437 feet, Struek very heavy vein of gas at
858 feet.
The gas from this well, by calculation, would supply fuel to run the
rolling mill and machine shop boilers, being therefore equal to'100 tons
of coal per week.
The pressure of gas would sometimes lift the tools 20 or 30 feet in the
hole, tools weighing 1,700 pounds and repe 3800 pounds. ‘The flow of gas
is enormous and continuous.
No. 12 well, on Queenstown Run; December 9, 1871—April 12, 1872;
water cased out at 394 feet, Struek heavy vein of gas February 2, at

725 feet, which caused a flow of water until March 1, when casing was
put in and the water stopped off.
Struck oil at the top of third sand April 4, at 1, 183 feet, the rock being
nearly all good pebble rock ; after passing through it (1,200 feet) drilled
12 feet into slate for a pocket ; tubed well April 12 ; commenced pumping
12 barrels a day, and the well is now doing 13 barrels. Much gas all the
time. Cost $6,557.
No. 18 well, on Queenstown Run; January 2, 1872—May 8, 1872;
water cased out at 290 feet. Best show of oil at 1,390. Cost $6,671.
No. 14 well, on Queenstown Run; June 11, 1872—September 2, 1872 ;
water cased out at 227 feet. Little oil in third sand ; will push it deeper.
It only remains to give vertical sections of the Measures passed through,
premising, that the Great Conglomerate No. XII, the base rock of the
Coal Measures forms the low cliffs at water level in the river valley ; all
the hills being built up of the nearly horizontal Lower Coal Measures or
Allegheny River System, and the underground of Sub-Carboniferous and
Devonian.
The following records of wells No. 4 and No. 5 of the foregoing descrip-
tion were made from labels on sample bottles, marked daily by the well
drillers, and are not supposed to be perfectly reliable, but are neverthe-
less for the most part accurate notations of the character of the Sub-car-
boniferous and Upper Devonian Measures penetrated in reaching the
oil-bearing strata.

It is a pity that the above records are so defective. The intervals
between the numbers given are in many cases large and not noted, and
must not be taken as the thicknesses of the rocks named.
There is, however, a positive value in allsuch records, however defective, ~
as may be noted by the recurrence of the red rocks in the above lists.
These may define the position of the great red formation of the Paleozoic
series No. IX of the Pennsylvania State Survey, the representative of the
Old. Red Sandstone of English geologists, and the Catskill Formation of
the New York geologists.
In Well No. 4 it is noted once only as being struck at 1,126 feet.
In Well No. 5 it appears at 750, 805, 826, 930, 972 and 1,026 feet.
The thickness of the Conglomerate No. XII is accurately determined
in Well 4 at 190 feet, and in Well 5 at 170 feet.
The thickness of the Conglomerate No. XI1 in the salt well 45 miles
further down the river, as determined (not with entire accuracy) from
the Record, published on p. 65, vol. X., of the Proceedings A. P.&.,
April 1865, is 4944-3843 == 160 feet; or, if the top of XII be placed at
the ‘‘White Sand’’ 4404 and all the ‘‘Gray Sandrocks”’ be included
down to 666//11, == 220 feet.
At Sligo Furnace on the Clarion (p. 68, vol. X.), the Conglomerate No.
XII, seems to be only 117 feet thick, soft red slate of XI under it only
3 feet thick, and the red and blue slates of [X lie 786—183 = 603 feet
below its base, or 720 feet below its top.
The resemblance of this to the record of Weil No. 5, given above, is
very observable. Thus, in Well No. 5, the red rocks of IX are first
struck at 750—45 — 715 feet beneath the top of the Conglomerate.
In the Sligo Well (15 or 20 miles to the northeast of it), the top of the
red rocks is 786—66 = 720 feet beneath the top of the Conglomerate.
In the Well No. 5, the redrocks are noticed at intervals from 750 to
1026 = 276 feet.
In the Sligo Well, the red rocks occupy an interval of only 118 feet.
It must be taken into consideration, however, that the lowest red rocks
of the well No. 5 may represent not No. IX, but the Red Beds of VIII,
described in my report to Professor H. D, Rodgers, in 1841, and pub-
lished in his Final Report of the Geology of Pennsylvania, under the
1872.] 569 [Lesley.
head of the Geology of the Wellsborough Valley or Tioga River District
in Tioga County. To trace the thinning away of these calciferous and
ferriferous red beds of VIII (Lower Divonian) on their way towards Ohio,
underground, is one of the desiderata of American geology.
Other well-boring records are published on pages 227 ff, vol. X, Proc.
A. P. §., but most of them are confined to the Coal Measures. Those on
p- 288 ff, however, penetrate the Deyvonians to considerable depths and
show the red rocks in positions analogous to those described above.
In one well, at the head-waters of the Clarion, the mouth of the well
being 3870 feet below a coal bed, and also below the bottom of XII, the
red rocks of IX (?) occur from 216 to 415 —an interval of 200 feet,
which is abont the normal thickness of IX in this zone of its decresence
westward, The Manchester (Tioga river) red beds (?) were struck at in-
tervals from 925 to 956 = 41 feet, 7. ¢., with an interval of 510 between
their top and the bottom of IX.
In the Glade Well near Pithole (page 241, vol. X), in the Oil Creek
country, the red slates were first struck at 196 and got through at 318,
the interval being 122 feet. Some red shale was then struck near the
well bottom (abandoned, no oil) at 612, 7. ¢., 294 feet below the bottom
of the upper red shales.
These also probably represent UX and the Manchester red beds, with a
diminished interval due to westing.
These red rocks correspond to the Marshall group of Michigan, of
Winchell (Proc. A. P.8., vol. XI., p. 74), the Gritstone redrocks above
and the Chocolate shales below (the latter just over the Hamilton) in
Ohio (Idem, p. 75), and to the Brown shales of the Keokuk group of
Indiana. They are very noticeable to the traveller on the railways cross-
ing Northern Ohio.
Norr.—l have received the following letter of explanation respecting
the wells at Brady’s Bend :
Sr. Lours, Mo., November 13, 1872.
Dear Sir:—The detailed surveys were begun and mostly made under
my direction, and the wells Nos. 6, 7, 8 and 9 were located by me. This
would be of no interest to you or the public were it not that the location
of these wells was the result of a long, carefully pursued, and at least
apparently successful investigation into the laws of the distribution of
the oil in the ‘‘sandrocks.’’
You had already shown that these rocks existed there and at what
depth, and had also shown that the general stratography of the district
rendered it reasonably certain that oil would be found there, and this had
been confirmed by the results of boring in the case of two of the five wells
sunk,
I tried to find the law of distribution in its application to narrower
limits, so as to decrease to the utmost the risks, and inerease to the
utmost the chances in sinking wells.
Of the five sunk before I went there, two were productive ; of the four
sunk since I left, one is productive; of the four I located, namely, Nos.

the four, was located under restriction to the Lower Campbell tract.
No. 8, the most productive, was the last one I located without restriction.
Nos. 6 and 7 were both down before any other well was started in the
Whiskey Run or Queenstown Run field. The same principles which
guided the locating these wells, led me to advise the Brady’s Bend Iron
Company against trying the Upper Campbell tract, and the results of
boring there by other parties have confirmed their correctness, and there
have been so many confirmations that my confidence in the principles
amounts to conviction.
In opening the Whiskey Run or Queenstown Run field, I simply fol-
lowed the general line of strike from the Armstrong Run field; but in
locating individual wells I sought lines and areas of deposition of coarse
pebbles in the ‘“‘sandrocks”’ out of broken condition of the ‘‘sandrocks.’’
[ had not so far completed the research into the laws which govern the
‘direction and position of these lines and areas that I felt free to com-
municate them when I left the oil country, but hope to push ‘the inves-
tigations further hereafter. Meanwhile it may be of some -interest that
the above results have followed an effort.pursued by scientific methods
to find and apply such laws.
Yours, very respectfully,
JAMES E. MILLS,
Vice President Big Muddy Iron Company.

The death of Gen. George Gordon Meade, on the 6th in-
stant, at Philadelphia, aged 56, was announced by Mr. Trego.
On motion, Gen. A. A. Humphreys was appointed to pre-
pare an obituary notice of the deceased.
Mr. Gabb described the results he arrived at in making up
a summary from tables of undoubted Miocene fossils, col-
lected. by him during three years of exploration in Santo
Domingo. These tables double the fauna hitherto de-
scribed. Instead of the normal percentage of extinct to
recent species according to Lyell’s formulas, it appears that
the San Domingo Miocene holds 217 extinct and 97 living
forms; these living forms existing on both sides of the
present barrier of Central America, on top of which barrier
lie Miocene rocks. Mr. Gabb stated that he had just. fin-
ished the study of the Miocene Fossil Mollusea, collected
during his recent geological examinations in Santo Domingo.
He found 217 extinct species, and 97 which he recognized’
as living; 15 of these latter are peculiar to the “Panama
Province,” having disappeared from the Caribbean waters
since the Miocene period. One or two are found in the
Eastern seas only, and others are now living on the opposite
side of the Atlantic, or on the Atlantic coasts of North and
South America; while still others are closely allied to-spe-
‘ies or belong to genera only living at present in the seas of
Australia and Southern Asia.
The most interesting feature connected with these fossils,
however, is that notwithstanding the proportion of liv-
ing to extinet forms is about one-third, yet, from the “ facies”
of the collection, from the presence of antique types among
the genera, and from the vertebrate remains, such as Car-
charodon, Megalodon and other well-known Miocene species,
there seems little doubt but that the formation was correctly
referred to that age by previous writers, such as J.. Carrick
Moore, Etheridge, and Duncan.
Lyell established the rule many years ago, that the typi-
572
cal Miocene contains but 17 per cent. and the Pliocene from
35 to 50 per cent. of living species. But that rule, while i:
applies perfectly well to the local deposits on which it was
based, is too empirical to be followed elsewhere, except in a
very general manner and where the other data are in accord.
An essential objection to the numerical rule exists in the
different values that students place on specific characters.
No two writers agree on this subject. Besides, as regions
become more thoroughly worked up, discoveries of additional
fossils, or the finding of living species, previously known
conly as fossils, vary the proportions constantly. The general
deductions, therefore, drawn by an experienced palseontolo-
gist from large collections, are safer guides than any table
of percentages

My Dear Pror. LEsLey:
The steamer did not sail on Saturday and I
have availed myself of the delay to run up here. It was very fortunate,
since I have had the opportunity of seeing Dr. G. A. Maack, and of
learning from him some of his geological results on the late Selfridge
Expedition on the Isthmus. Please have the following. note added to
my paper, with the permission of the Society :
The results of the explorations of Dr. Maack last year, on the Isthmus
of Darien, put at rest the question of the late geological origin of the
Isthmus. He found three late Tertiary strips extending entirely across,
proving three channels at least in the Miocene, and some of the deposits
indicate a much later era of elevation. One of these, 10 miles inland
from Panama, evidently Post Pliocene, is at least 150 feet above the tide.
In a very cursory examination of his fossils I detected the following
species, also found in Santo Domingo :
Melongena melongena.
Murex recurvirostris.
Malea ringens.
Terebra robusta.
Conus pyriformis.
Natica sulcata.
Jerithium plebium.
Turritella.
Cypreea exanthemata (v. cervinella).
Venus paphia,
Jardium Haytense.
Pecten papyraceus.
Dr. Maack in his report calls the older beds of Panama, Pliocene. They

seem to me nearer in age to the rocks which, in Santo Domingo, I called
Miocene, but whatever be their real age, the one fact is well established :
The Isthmus was elevated at a period not remote from the age of the
great volcanic outflow of the Sierra Nevada.
Yours, sincerely,
W. M. GABB.

December, 1872.
The Librarian stated that a large number of books and.
brochures needed binding; that the book-cases had again
become overcrowded by accessions; that certain classes of
books were seldom or never referred to; that the catalogue
in MS. of the Theological books and pamphlets was nearly
finished; and suggested that the book-cases might be re-
lieved and a benefit be conferred on learning by depositing
the Chemieal, Mineralogical, and Geological books, tempo-
rarily, in the new building of the University of Pennsy|-
vania.
On motion of Mr. Ruschenberger, it was
Resolved, That the Committee on the Library be requested to consider
the expediency of depositing in the library of the University of Pennsyl-
vania certain books now in the library of the Society, which are not much
called for ; and in ease they shall deem the same expedient, then to report
a plan for carrying the same into effect, which will insure tie use of the
books to the members of the Society, and also provide for the safe keep-
ing of the books so deposited, and their return to the Society when ealled
for.
And the Society was adjourned.
Stated Meeting, December 20th, 1872.
Present, 18 members.
Vice President, Prof. J. Crusson, in the Chair.
A letter from the Librarian of the Pennsylvania Ilistori-
eal Society, dated Philadelphia, Dec. 13, was read , requesting
the completion of their set of Transactions and Probedines
A. P.S., which on motion was granted, and the Librarian
authorized to act accordingly.
Letters of similar import from the Cornell University and
State Normal School at Fredonia, were on motion referred
to the Publication Committee with power to act.
A letter of envoy was received from Mr. Thomas Bland,
New York, 42 Pine Street, Dec. 16th, on the part of ay.
Rawson, of Barbadoes, presenting to thé Society’s Library
a copy of his report on the population of the island.
The death of a member, Mr. Thomas Sully, at Philadel-
phia, on the 6th ult., aged 89 years, was announced by the
Secretary.
The death of a member, Dr. René La Roche, at Philadel-
phia, on the 9th inst., aged 77 years, was announced by Mr.
Fraley, and on motion, Dr. Carson was appointed to prepare
an obituary notice of the deceased.
The death of a member, Dr. Samuel L. Hollingsworth, at
Philadelphia, on the 14th inst., aged 57 years, Was an- _
nounced by Mr. Fraley.
Mr. Cope desired to place on record an abstract, which he
communicated orally, of a paper on the Zoological Divisions
of the Earth, as proposed by Slater, Huxley and others,
giving his preference to that of Slater, and citing the num-
bers of species, ete., already described.
Dr. Wilcox exhibited a Japanese Magie Mirror, the prop-
erty of E. C. Bittinger, U.S. N., and carrying on its back
side the inseription “ Elevation—In the dust.” He read two
letters written by Prof. John Tyndall to Mr. Alex. Johnson,
in answer to a request for an explanation of the physical
phenomena of these mirrors, used in the Buddhist cultus.
Prof. Marsh gave a short account of the more remarkable
resul's of his explorations in the Rocky Mountains since
ce
O77
1870, viz.: His discovery of the first American fossil ptero-
dactyles, cheiroptera, marsupials, birds with biconcave ver-
tebree, monkeys (eocene) of low type, and dinoceria, a new
order of horned proboscidians with canine teeth.
Prof. Cope dissented from the propriety of at present
erecting the proboscidians so discovered into a separate order,
merely on the ground of their possessing horns and canines,
and gave his reasons.
Prof. Marsh also gave an interesting account of Mr.
Clarence King’s detection and exposure of the “ Arizona
Diamond Fraud,” and his own observations of the locality,
which is actually in Colorado, and not in Arizona. Had the
fraud not been exposed by the prompt energy of Mr. King
before the setting in of the deep snows, great suffering and
loss of life and a vast plunder of property would have ensued.
The Report of the Committee of Finance was read by its
Chairman, and the appropriations for the ensuing year
recommended therein, were on motion ordered :
