Some Tables for the Interconversion of Metric and English Units.
By PERsIFOR FRAZER, JR., A. M.
(Read before the American Philosophical Society, April 5, 1878.)
Capt. Kater, in 1821, as a member of the Royal Standard’s Commission,
appointed in 1818, made the determination of the meter to be 39.37079
inches. This was adopted by the Commission and was embodied into
the statute of the British Parliament enacted in 1824, establishing the
platinum standard meter in Paris as in length equal to 39.3708 inches of
brass at the temperature of 62° Fahrenheit, the platinum standard being
at 0° Centigrade, or 32° Fahrenheit, the temperature of melting ice.
Capt. Kater’s value was again sanctioned by Jaw in 1864.*
In 1866, the Royal Ordinance Survey, adopted 1 meter = 39.370432
inches, on the authority of Col. (then Capt.) A. R. Clarke, Superintendent
of the Office of the Survey at Southhampton.
In 1869, the more recent Royal Standard’s Commission, under the Presi-
dency of Astronomer Royal Airey, reported comparative tables, founded on
Kater’s value, which were published in a Parliamentary Blue Book, and
may be found at the end of the second Report of the Royal Standard’s Com-
mission, published in that year.+
The subjoined work was undertaken to supply a want which every physi-
cist and chemist, and, indeed, very many artisans and manufacturers have
felt, for a set of convenient and consistent tables for converting various
values of measure and weight from one into the other of the two systems
between which at present the calculations of the greater part of the civil-
ized world, both in science and trade, are divided.
Every one knows that a multitude of tables for this object are already in

existence, yet it must be apparent to any one who has compared them to-
gether that there are generally discrepancies between them.
For instance, three authorities which should command the confidence
of scientific men give the following values :

Only three authorities are here quoted, but the number might be almost
indefinitely increased. It is true that for most purposes these differences
being less than one thousandth of one per cent., would not seriously affect
the results ; but there are problems continually occurring where some rec-
ognized equivalent is most desirable, and still a greater number where it
is desirable that all the diverse terms employed should have been obtained
from the same original unit and by the same methods.
-It would be far better that all the English speaking world should accept
a wrong determination as the only Jegal one than that each person who
employs such reciprocal values should take a different standard, even if one
of the number could be absolutely right.
In all questions relating to the value of lineal, superficial and cubical
equivalents of the English and Metric units, including those defined by
law as a certain whole number and fraction of cubic inches or feet (e. g.
the bushel, barrel, stone-perch, &c.), the determination of Kater has been
taken, and squared, cubed, multiplied and divided until the expression for
the desired derivative of the meter was obtained in terms of some deriva-
tive of the inch, no decimals having been omitted until the final number
was reached ; when the shorter approximative expression has been sub-
stituted by an application of the well-known rules governing such cases.
The number of decimal places given has been in proportion to the im-
portance of the unit asa base from which to calculate other values. Thus
the number of places in the Grain—Gram equivalents is eleven (as in the
report of Mr. Upton, from which it was taken), whilst the Rood—Are being
less frequently used and especially being of less importance as a base from
which to derive other values, is given in five and six places respectively.
This method of separate calculation from the fundamental Inch-Meter
value has been employed tor each of the above-mentioned kinds of dimen-
sions, and the value of the metric unit in the Inch derivative has been con-
verted into the reciprocal or Inch derivative unit by simply dividing the
whole decimal into one and shortening as before. This is obviously to be
preferred to taking the reciprocal of the legal value of the meter in
inches, as the base of the calculation.

form of expressing the Fahrenheit in the Centigrade degree. Rankine is
responsible for the statement of the relation between English Heat Units
and French Calories, but both have been verified.
In weight the fundamental units (the value of the Gram. in Grains) is
taken from the report of Mr. Upton (Chief Clerk of the Treasury) to Hon.
John Sherman, Secretary, March 26, 1878, and from this value all the others
were calculated.
In fine, all the values here appended have been as carefully as possible
revised by the author, and, in addition, have had the benefit of the very
valuable criticism and corrections of Professor Chase, of Haverford Col-
lege, and of President Barnard, of Columbia College, the latter of whom
has conferred greater security in verifying them by the calculating machine.
In the case of lineal units, four of those most constantly recurring were
selected, and the values of one up to nine times each unit are given in
terms of the other. This method, which is employed in Crookes’ ‘‘ Select
Methods of Chemical Analysis ’’ (London, 1871,) permits any decimal mul-
tiple or fraction of one unit to be obtained with great accuracy in terms of
the other, by a change of the decimal point and a simple addition.
Thus, if it be required to find the number of inches in 348,4 centimeters,
the fraction would first be written decimally, 348.16. The value in inches
of three centimeters is 1.181124.

posed at base.
Our species, with one exception, occur from the regions west of the Rocky
Mountains, while the reverse is the case in Bostrichus. They are distin-
guished in the following manner :

Cylindrical, robust, piceous black, shining. Thorax a little broader than
long, apex with two hook-like processes pubescent at tip, in front roughly
granulate, toward the anterior angles serrate, posteriorly densely granu-
late, smoother near the hind angles which are prominent. Elytra coarsely
substriately punctured, declivity gradually convex, not margined nor cal-
lous. Body beneath sparsely punctulate, scarcely at all pubescent. Length
.88-.68 inch ; 9.5-17 mm.
This species is abundantly distinct from punetipennis by the prominent
hind angles of the thorax, the form of the declivity and the almost entire
absence of pubescence beneath. Crotch appears to have considered it the
female of the next species, and for that reason omitted it from the Check
List. I cannot convince myself that so many differences are sexual only.
Occurs from St. George, Utah to Arizona and Peninsula of California.

In the two specimens before me I detect no sexual differences.
Occurs at Fort Yuma, California.
DINODERUS Steph.
The species of this genus are of cylindrical form, sometimes very slight-
ly depressed. The thorax is covered with asperities in front in the man-
ner usual to the genera of this tribe.
Here again we have a species (brevis) in which the antenne vary from
the normal number of joints, there being in the one species six and in the
others five small joints between the second and the club. The second
joint of the antenne is usually nearly as stout as the first and short, in one
species, however, (punctatus) this joint is much more elongate than usual
as are also the third and fourth, this makes the antenne longer and more
slender; here also the antenne are fimbriate anteriorly.
The length of the three-jointed club as compared with the funicle ex-
hibits an amount of variation which indicates the propriety of suppressing
the name of one or other of the generic names Dinoderus or Rhizopertha.
The former is retained as it has the greater number of species in our fauna.
The surface of the body is sparsely clothed with short erect hairs, in
punctatus alone the pubescence is not erect.
The declivity of the elytra is normally convex, two species have it flat-
tened and limited to a varying extent by a ridge (punctatus, truncatus).
The other variations of structure are more strictly specific.
In accordance with the relative importance of the characters above given,
our species may be arranged in the following manner :
A. Antenne 10-jointed, form elongate cylindrical.
Declivity of elytra convex, not acutely margined.
Margin of thorax coarsely serrate.

Head shining, smooth, granules small, flat............substriatus.

This and the preceding species are closely allied and differ only in
sculpture. In the former the intervals are broken up into closely placed
tubercles, in the latter the punctures of the intervals are more evident and
the intervals are continuous, their summits being submuricate.
Occurs particularly in the Northern States and Canada.

This species differs from the preceding in its rougher sculpture, and
denser punctuation, the declivity in the former species being punctured, in
this granulate.
Occurs in the Southern States ; also, in Michigan.

This insect appears to be cosmopolite, having probably been distributed
in articles of commerce. Numerous specimens were observed in the wheat
at the Centennial Exposition. It probably occurs over our entire country,
as I have specimens from Arizona.

riorly indistinctly granulate, and more shining. -Elytra densely and irregu-
larly coarsely punctate, intervals not elevated, declivity feebly convex,
suture slightly elevated, on each side a more prominent but small denti-
form tubercle, at sides of apex acutely margined. Body beneath moder-
ately densely punctate. Length .18 inch; 4.5 mm.
This species is abundantly distinct in the structure of the antenne.
Occurs from Pennsylvania westward.
D. truncatus, n. sp.

dise anteriorly, roughly granulate, posteriorly, feebly but densely muricate.
Elytra with coarse, deep, closely placed punctures, arranged in moder-
ately regular striz, except near the scutellum, intervals not elevated, de-
clivity abrupt, flat, densely punctate, acutely margined. Body beneath

The marginal ridge of the declivity encloses an exact semi-circle, while
the face of the declivity is nearly vertical to the axis of the body.

tured, disc sub-carinate at middle posteriorly, and on each side of this a
feeble depression. Elytra cylindrical, obtusely declivous posteriorly, sur-
face coarsely and deeply and moderately densely punctured. Body be-
neath piceous, legs paler. Length .12 inch; 3 mm.
This species differs from all the others by its eleven-jointed antenne, the
additional joint occurring among the small ones between the second and
the club. Its form is also shorter, and more robust, resembling in this re-
spect some of the species of Xyleborus. In this species we have the third
instance in our fauna of the variation of the number of antennal joints
within what must be considered generic limits.
Several specimens sent me by Dr. Summers from New Orleans.

Polycaon, the first joint being very small.

With Polycaon I have united Hxopioides, the ten-jointed antenne being
the only differential character. There are species belonging to the latter
genus with the declivity margined, but not exactly as in the normal
series of Polycaon. Acrepis does not differ essentially from Psoa, and
another instance is thus presented of the analogy of the fauna of the west-
ern side of our own continent, with that of the western side of the eastern
continent.
POLYCAON Lap.
This genus contains species of moderate size, the first black and slightly
depressed, the others piceous or brownish and cylindrical.
The antenne exhibit important differences. In Sfouwtii the fourth joint
is rather elongate, and 4-8 slightly compressed, these taken together longer
than the club. In the other species the third and fourth joints are of
nearly equal size, and sub-moniliform, and taken together not longer, rarely
as long as the club.
Exopioides (which is here suppressed) differs only in having one joint
less in the funiculus.
The prosternum separates moderately widely the coxe, and is slightly
dilated behind in Stowtz7, or not dilated in the others.
The elytral declivity presents two forms, that in which the tip is gradu-
ally declivous, or that in which the declivity is more or less flattened, and
limited by an acute edge, thus far an equal number of species occurs in
each.

The epistoma is rather deeply emarginate in Stowtii, in the other species

By an arrangement of the above characters our species may be tabu-

slightly wider at base than the thorax, and feebly emarginate, disc with
rows of moderately coarse punctures which become somewhat finer to-
ward the tip. Prosternum coarsely punctured, side pieces nearly smooth.
Metasternum smooth at middle. Abdomen coarsely and sparsely punc-
tured, the first segment smooth at middle. Pygidium sparsely punctate.
Length 5 mm.; .12 inch.

Marquette, Lake Superior. The punctures of the entire
surface are coarser than in any other of our species. It must
be considered the intermediate form between those with the
long and those with the broad thorax.
34. Pedilophorus subcanus. Longer-oval, convex, rounded be-
hind, obliquely narrowed in front of the elytra, black, irregularly mot-
tled with very short gray pubescence like hoar frost, and thinly clothed
with short erect black bristles. Beneath finely, densely punctured, finely
pubescent, legs piceous; tarsi paler, fourth joint with a long lobe.
Length 4.4 mm ; .17 inch.
Escanaba, Lake Superior. In form and pubescence this
species resemembles Byrrhus, but the tarsal lobe requires its
reference to the present genus, with which it also agrees in
having the mandibles not covered by the prosternum in re-
pose.
3). Paromatlus teres. Cylindrical, but not slender, shining black ;
head and prothorax punctulate, elytra finely not densely punctured, each
with faint traces of two oblique striz near the base; sutural stria want-
ing. Pygidium very finely punctulate, under surface finely and sparsely
punctured ; mesosternum emarginate in front, marked with a fine lateral
line; prosternum flattened without strie. Length 2mm ; .08 inch.
Sault St. Marie ; one specimen. This species only differs
from P. seminulum by the cylindrical form, in which it de-
ceptively resembles Teretrius americanus; by having the ely-
tra more finely punctured, and by the entire absence of the
sutural stria.
The following species may be conveniently described on
the present occasion.
36. Hetzrius Blanchardi. Oval-quadrate, brown, shining, of the
same form as H. brunneipennis, sparsely pilose with long slender sub-erect
yellowish hairs. Head opaque, finely punctulate, broadly concave. Pro-
thorax with the sides slightly nicked at the middle, lateral lobes of the
‘dise obsoletely punctulate, divided behind the middle by a transverse
groove, hinder part deeply margined on both sides ; the impressed groove
separating the lateral lobe from the disc is much deeper and broader at
the base. Elytra with three very fine strive, the inner one effaced behind
the middle. Pygidium opaque, very finely and densely punctulate. Pros-
ternum narrow, flat, densely punctulate, lateral edges well defined. Length
2mm; .08 inch,

species, which would otherwise have remained undeter-
mined.
37. ADgialia rufa. Elongate, cylindrical, not very convex, rufous.
Head finely scabrous, with an obsolete transverse impressed line ; epistoma
very finely margined, sub-truncate. Prothorax scarcely wider than long,
sub-quadrate, sides very slightly rounded, fringed with stiff hairs, serrate
towards the base, which is broadly rounded and distinctly margined ; front
angles prominent, hind angles rounded, dise coarsely sparsely punc-
tured with some fine punctures intermixed. - Elytral strive deep, distinctly
punctured, interspaces smooth. Scutellum small, smooth. Front tibiz
with three large teeth, middle and hind tibive gradually but moderately di-
lated, transverse ridges short; spurs of hind tibiee long, hind tarsi two-
thirds as long as the tibie. Length 4.5 mm ; .175 inch.
Marquette, Lake Superior, two specimens; California,
( precise locality unknown, probably from the Sierra Nevada),
one example. The humeri in one Lake Superior specimen
are/prominent and tubereulate, in the other two rounded ;
in the former the spurs of the hind tibiz, though not longer,
are more slender than in the two with simple humeri. These
differences are probably sexual, but cannot be fully investi-
gated without more specimens.
For the easy recognition of our species of this genus |
have enlarged the table given by Dr. Horn (Trans. Am. Ent.
Soc., 1871, 293), as follows:

acters given above; the do are however easily recognized.
68. Pityophthorus hirticeps. Yellow brown, shining, cylindri-
cal, less slender than the two preceding species, sparsely retose with fine,
erect yellow hairs. Prothorax a little longer than wide, roughened con-
centrically for one-third its length ; sides and posterior part strongly, rather
densely punctured, with a narrow smooth median space. Elytra with ap-
proximate rows of punctures, interspaces irregularly transversely rugose ;
apical declivity retuse and crenate, deeply concave near the suture, which
is elevated and also crenate. Length 1.6 mm.; .06 inch.
o'. Head broadly concave and opaque, fringed with long yellow hair.
2. Head slightly convex, strongly punctured.
Marquette, Lake Superior. Related to the two preceding,
agreeing with P. annectens in sexual characters, but with the
erenations of the apical declivity of the elytra stronger than
in P. consimilis, while the form is a little more robust than
in either.
69. Pityophthorus pusio. Cylindrical, shining, piceous, witha few
erect yellow hairs behind the middle of the elytra. Prothorax not longer than
wide, roughened in front almost to the middle, strongly and densely punc-
tured at the sides and behind, with a large, smooth, well-defined dorsal space.
Elytra with small punctures, arranged in tolerably regular rows, apical
declivity broadly concave, slightly retuse each side, with about three very
small teeth; suture elevated, also with three or four slight inequalities.
Front tibize with two very faint small teeth. Length 1.6 mm.; .06 inch.
Marquette, Lake Superior ; one specimen. The head is re-
tracted so that the front cannot be seen. This species is of
the size and form of P. pulicarius, but the elytral sculpture
and the apical declivity are quite different ; it is more nearly
related to the Californian P. puncticollis, but ditters by the
more robust form, and by the sparse crenations of the apical
declivity, which are wanting in that species.
70. Pityophthorus opaculus. Cylindrical, slender, testaceous.
head and disc of prothorax darker ; anterior half rather strongly asperate,
sides and posterior half sub-rugosely punctulate, dorsal line smooth, narrow.
Elytra finely alutaceous, nearly opaque, marked with scarcely perceptible
distant strize of very fine punctures ; apical declivity neither retuse nor con-
cave, suture elevated, limited by a distinct striz. Length 1.3 mm.; .05 inch.
Marquette ; one specimen. This species must be placed
after P. comatus in my table (Rhynch. 352). The head is pune-
tured, and slightly convex, the legs and antenne are yellow.

Marquette, Lake Superior; rare. This species, as is shown
by the examination of well preserved specimens, has the club
transversely annulated,and therefore belongs to Pityophthorus.
There seems to be no sexual differences in the declivity of
the elytra, but the @ has the head fringed with very long
hair. .
73. Xyleborus punctipennis. Slender, cylindrical, piceous,
shining, thinly clothed with long erect yellow hair, granulato-asperate for
more than one-half the length, sides and behind densely and coarsely punc-
tured; smooth median line rather wide, very distinct. Elytra coarsely
punctured, though not in altogether regular rows, suture elevated, and su-
tural stria deep for the whole length; declivity oblique, retuse, concave
part coarsely punctured ; there are two acute discoidal cusps, and several
small indistinct marginal ones, the most anterior of which is near the su-
ture and more prominent. Front tibie moderately dilated, bidentate.
Length 2.5 mm.; .10 inch.
Marquette, Lake Superior; one ¢ specimen. This species
might be easily confounded with Pityophthorus sparsus, but
on comparison the difference in the antennal club is quite
obvious; in the present case it is thicker, and obliquely
truncate at tip, so that the proximal half at least is smooth
and shining, and limited by a curved line. The punctures of
the prothorax and elytra are coarser and more numerous, and
the apical declivity is also punctured.
74. Xylocleptes decipiens. Slender, cylindrical, brown, shining,
sparsely clothed with erect yellow hairs ; antenne and Jegs yellow. Pro-
thorax longer than wide, slightly asperate in front with transverse rugosi-
ties ; sides and behind coarsely but not densely punctured ; median line
and a smooth space each side well defined. Elytra \ coarsely punctured,
punctures not arranged in rows; declivity nearly perpendicular, scarcely
retuse, slightly impressed along the suture, which is feebly elevated. Head
convex, finely punctured ; front tibiz moderately dilated, serrate with four
or five very small] teeth. Length 1.3 mm.; .05 inch.
Detroit ; one specimen. This species greatly resembles in
sculpture Pityophthorus pulicarius, but is more slender, and the

antennal club is very different ; the sutures are long curves,
concentric with the apical margin, and the first joint is gla-
brous, shining and elliptical in form.
To this genus should be referred the Alaskan Bostrichus
concinnus Mannh. Bull. Mose. 1852, 358; Tomicus conc. Lec.,
Tr. Am. Ent. Soc. 1868, 164; Rhynch. 367. Only 22 have
thus far been collected.
75. Tomicus balsameus,. Blackish piceous, or brown, cylindrical,
shining, clothed with long erect yellow hairs. Prothorax longer than
wide, asperate for about one-half the length, then strongly but not very
densely punctured at the sides and behind ; median space smooth, narrow,
badly defined. Elytra with strie composed of large rather distant punc-
tures, interspaces with equally large but very distant punctures ; declivity
concave, sparsely not deeply punctured, margin with several small teeth
and two large ones ; the apical part of the margin is not a continuous ridge.
Front tibiz dilated, with fourdistinct teeth. Length 2.3 mm. ; .09 inch.
oO Head flat, shining, hairy with very long yellow hairs ; the four larger
teeth of the apical declivity less prominent.
2 Head finely punctured ; carinate with an acute elevated line ; four
larger teeth of apical declivity very prominent.
Central New York, where it has seriously injured the
forests of Abies balsamea. For an account of the ravages of
this insect see the Report of the Botanist in the 28th An-
nual Report of the New York State Museum of Natural
History, 1874, p. 32-38. I am indebted to Mr. J. A. Lintner,
of the State Museum, at Albany, for a series of speci-
mens. Some care will be necessary to distinguish this in-
sect from Xyleborus punctipennis, but apart from the differ-
ences of theanntenal club, the prothorax of T. balsameusis less
densely punctured, the strive are more distinctly formed, and
the apical declivity is less punctured, with the teeth (2)
more prominent, and not distinctly separated from the ele-
vation of the margin of the declivity. The front tibiz are
more distinctly toothed. The sutures of the club are straight
and transverse, so that it belongs to the division Orthotomicus
Ferrari, and may be placed in the table (Rhynch. 363), after
latidens, to which it has no resemblance.

Prothorax darker, opaque, finely asperate in front, indistinctly punctulate,
thinly sprinkled with very small ochreos scales. Elytra shining, punc-

77. Micracis asperulus. Slender, cylindrical, black, entirely
opaque. Head not concave, scarcely punctured. Prothorax more strongly
asperate in front than in the preceding, scarcely punctured behind, sprin-
kled with small yellowish scale-like hairs. Elytra obsoletely striate,
densely rugosely punctured, interspaces with rows of very short stout
bristles as in M. opacicollis. Eyes very narrowly separated beneath. An-
tenne ferruginous, club with broadly curved sutures. Legs ferruginous.

the preceding, but quite different in sculpture.
78. Scolytus unispinosus Lec. Rhynch. 372.
Marquette, Lake Superior; one specimen. This differs
from the two specimens from Oregon upon which the species
was established, by the punctures of the elytra being not so
small, and by the spine of the first ventral segment being
much less developed, becoming in fact a small tubercle ; the
elytra are fringed with brown. I consider none of these as
specific characters.
79. Scolytus rugulosus Ratzcburg, Ins. i, 230; pl. x. f. 10.
This isa suitable opportunity to notice the introduction
of this European species into the United States. I have re-
ceived specimens from Elmira, N. Y., where it attacks peach
trees. According to Ratzeburg it is rare in Germany, but is
found upon plum and apple trees.
80. Choragus Harrisii. Elongate-oval, sub-cylindrical, blackish-
brown, shining, finely pubescent. Prothorax finely less densely punc-
tured, not opaque ; elytra with deep coarsely punctured strive, interspaces
not wider than the strie, scarcely punctulate. Length 1.2 mm.; .05 inch.
Detroit ; August ; one specimen. Differs from our other
two species by being more distinctly (though very finely)
pubescent and by neither the prothorax nor elytra being
opaque.

4. Description of the Larva of MICROMALTHUS DEBILIS Lec.
By H. G. HuBBARD.
Color transparent white, mandibles and anal appendage castaneous.
Form cylindrical, very slightly flattened beneath, hardly narrowed lat-
erally in front and behind. Body glabrous, except a few hardly visible
hairs upon the sides, without legs. Length 0.10-.12 inch.; width about
0.03 inches.
Head not quite as broad as the segments of the abdomen, convex, trans-
verse, enlarged posteriorly; sides rounded, convex ; anterior border nearly
straight, posterior border emarginate ; above and below a few long bristles.
No ocelli.
Antenne short, inserted in depressions on the anterior angles of the
head, of four joints increasing in length, the first very short, transverse,
the second smaller, about as long as broad, the third longer than the pre-
ceding, with a short oval lobe below, before the tip, the fourth twice as
long as the third, slender, blade-shaped, tipped with a minute spine.
Labrum trausverse, somewhat enlarged anteriorly, borders nearly
straight, anterior angles rounded, with long stout spines above and below.
Mandibles as long as the antenne, stout, curved, three-toothed with a large
hatchet-shaped basal lobe, obliquely ridged upon the under surface.
Maxille, very large and prominent, longer than the mandibles ; with
palpi of three joints, the first and second short, cylindrical, the third as
long as the first and second united, more slender, flat, and divided nearly
to the base into two superimposed lobes bearing papille ; maxillary lobe

divided anteriorly by a deep notch into two portions, the apical, smaller
and narrower than the basal, blade-shaped, tipped with a long slender spine,
and bearing four long and stout teeth projecting at right angles to the lobe,
like the blades of a half-opened penknife ; the basal portion with two rows
of teeth on the border, and a slender tooth and bristle at the apex.
Labium consisting firstly, of an elongated, triangular mentum, with the
apex thickened in aconical protuberance, bearing a pair of bristles near the
middle, and another pair upon the thickened tip ; secondly, of a transverse
palpiger, bearing small fleshy palpi of two subequal joints, and its anterior
border prolonged between them in a conical projection; thirdly, of an
elongated, convex, corneous ligula, enlarged anteriorly, with straight
borders and a pair of bristles near the tip. Behind and above the mentum
and plainly seen through the transparent tissues, is a broadly triangular,
horny piece, the base of which extends between the hinges of the mandi-
bles, and the apex reaches as far as the middle of the ligula; upon the
upper surface oblique grooves on each side correspond with the ridges
upon the basal lobes of the mandibles, into which they lock when the man-
dibles are closed.*
Thoracic segments slightly thicker than the abdomen, the first longer,
the two following subequal in length.
Abdomen cylindrical or slightly depressed, of nine segments, the first ,
eight subequal, transverse, each with a few long bristles, the ninth conical,
scatteringly covered with long bristles, terminating abruptly in two minute
toothed appendages, one proceeding from the dorsal surface, and arching
downwards, the other from the ventral surface, curving upwards, and re-
sembling two hands with partly extended fingers, having the palms
turned towards each other. The upper and longer appendage appears to
be tubular for one-third of its length from the base, the remainder is con-
cave beneath, and terminates in two terminal and six lateral teeth, directed
downwards, their bases forming longitudinal ridges on the concave under
surface. The lower appendage is shorter, more strongly curved, and in the
opposite direction, concave above, expanded into a palm at the end, with
eight teeth as in the preceding; the concave upper surface is distinctly
denticulate.
The larva lives in damp situations, in the soft, crumbling wood of old
oak logs, which have become entirely disintegrated and colored dark red,
probably by a microscopic fungus. A number of larve, pupx, and imagos
were found together in a small portion of such a log on August 17th, 1874,
at Detroit, Michigan.
As Dr. LeConte has placed this insect in the family Lymexylide, it will
be interesting to compare its larva with that of Hylecwtus lugubris Say,
specimens of which are before me. The larve of Hylecwtus were taken
from cylindrical burrows in the solid wood of the American linden, It
* This piece and the mandibles, the forms and relative positions of which are
shown in fig. 9 of the plate, though very conspicuous in dissections under the
microscope. are omitted in fig. 5 in order to avoid obscuring overlying parts.
Hubbard. } 668 [April 18,
has a cylindrical body of twelve segments; a globular head, with two
large ocelli, which are, however, covered by the epidermis ; the first tho-
racic segment is enlarged, and partly covers the head, like a hood ; the
three thoracic segments bear well-developed legs ; and the abdomen termi-
nates in a long tapering style, toothed and concave on the upper surface,
and turning upwards at the end ; the stigmata are large and in their normal
positions, one pair beneath, on the thorax, and eight pairs on the sides of
the abdominal segments.
The antenne are four-jointed, exceedingly minute and stout, and, as in
Micromalthus, have the third joint lobed beneath, an apical spine, and oc-
cupy similar positions on the anterior angles of the head; the maxill also
have the lobe divided into an upper and lower portion, although the sepa-
ration is not very distinct, and appears under the lens as a corneous line,
the spines upon the lobe are slender and not markedly different upon the
two portions. The labrum and labium are stout and thick, but do not pre-
sent important structural differences from the same parts in Micromalthus.
The mandibles are simple or slightly notched, the basal lobes not promi-
nent, but finely ridged, and closing upon a triangular corneous piece which
lies above the mentum. All the parts of the mouth in Hylecwtus are
smaller, stouter, and simpler in their structural details than the correspond-
ing organs in Micromalthus, differences which perhaps have some relation
to the harder material in which the former lives. Notwithstanding the
striking difference in their external forms, the important structural analo-
gies between the antenne and mouth parts, seem to indicate a relationship
between these two larval forms.

teriorly and laterally, enclosing the latter somewhat as in a whalebone
whale. The fissure of the mouth is short, only reaching the vertical line
from the anterior nostril. Eyes small, without free border, much nearer
the snout than the gill opening, one-twelfth the length of the head, which
latter enters the length without caudal fin, 8.5 times. The depth at the
base of the dorsal thong is equal to the length of the head. Anal radii 171.
Scales very large, in only nine longitudinal rows at the base of the dorsal
thong. Color olivaceous, with a pale dorsal band which reaches the dorsal
thong, and a pale narrow band on each side near the dorsal band. Length
M. .165; length to origin of anal .020; length to base of dorsal thong .096.
This species resembles remotely the S. schottii of Steindachner, but differs
from it and from all the other species in the much enlarged mandible and
the large scales.

This genus is Curimatus with a clupeiform branchial apparatus. In
both the species the rakers on the anterior four arches are bristle-like,
while those on the fifth resemble somewhat the pharyngeal teeth of Catos-
tomide, although flexible.
This genus has never been distinguished from Curimatus until the
present time. It is not unlikely that the second species included by Spix in
Anodus (An. latior) is a Curimatus, but the A. elongaius must be regarded
as the type of the genus. Cuvigr established Curimatus on the C. cypri-
notdes (Salmo edentulus Bl. fide Gthr.) but included in it erroneously the
Anodus elongatus, in which he is followed by Gunther.
Since the above was written I learn that Professor Gill has described this
genus under the name of Hlopomorphus, in a recent number of a popular
journal.
Char. Specif. General form slender, head elongate, and with acuminate
muzzle, with the mandible projecting, beyond the premaxillary border.
Length of head entering total without caudal fin, three and two-thirds
times ; depth of body at dorsal fin, less than one-sixth of the same. Eye
large, one sixth of length of head entering one and one-fourth times into
leneth of muzzle and interorbital space, which are thus equal. Opercular
bone as long as deep; interoperculum large; extremity of maxillary ex-
tending a little beyond vertical line from anterior rim of orbit.

While the preceding species has rather clupeiform character, the present
one looks like a Hemiodus, and particularly the H. microlepis, with which
it was found associated in the collection. It differs much from the H. me-
lunopogon in the even lips, and the extensive adipose membrane which
closes the eye to an even greater degree than is found in the H. mécrolepis,
reducing it to a vertical fissure. Radial formula D. I. 10; C.3+ 19+ 3;
A. I. 11; V. 12; P. 19, reaching half way to ventrals; ventrals reaching

ter of the eye as seen through its adipose covering is a little less than
one-fifth the length of the head; and is one-half the interorbital width
measured over the strong convexity of the frontal bone. The maxillary
bone makes an angle with the premaxillary, and extends as far as the line
of the anterior border of the orbit ; the greater part of its length passes be-
neath the edge of the preorbital bone. The opercalar apparatus is elon-
gate, but the operculum is deeper than long. Total length M. .205 ; length
of head .047; length to origin of dorsal fin (axial) .082; do. of ventral

54. CURIMATUS ALTAMAZONICUS, Sp. nov.
This is a robust species with small scales. The form is elongate-oval,
and the head wide. The pectoral region is not flattened nor covered with
roughened scales, while the ventral line from the ventral fins to the vent is
keeled, but not serrate. The dorsal fin is elevated, its anterior rays being
four-fifths as long as the head.
Radii; D. I. 10; A. 1.12; V.9; P.13. The pectorals do not reach the
ventrals, nor the latter the vent. The ventrals originate below the fifth
dorsal spine. First dorsal ray much nearer the end of the muzzle than the
base of the caudal fin. Scales 25-94-22. Depth at first dorsal ray entering
length minus caudal fin 2.7 times. Length of head in the same three and
two-fifth times. The eye enters the length of the head four and four-fifth
times, and twice in the moderately convex interorbital width. Lips equal,
the inferior closing within the superior. Maxillary bone short, not extend-
ing behind the line of the nares. Color silvery without spots on the body
or fins. Total length M. .200; length of head .049 ; do. to origin of dorsal
fin (axial) .070; do. to origin of ventrals .O80 ; to origin of anal fin . 124.
This species appears to be nearest the C. latéor Spix. judging from de-
scriptions. In that fish the anal rays are said to be 14-15, and the dorsals 12.

the postventral region also flattened, and without distinct median keel.
Radial formula D. I. 10; C.2+4+19+ 2; A. I. 8; V.9; P. 16. The pec-
torals nearly reach the ventrals, which originate below the middle of the
dorsal fin, and reach to the vent. The anal fin has a short basis which is
equal to its distance from the vent ; folded backwards it reaches the base
of the caudal fin. The elevation of the dorsal fin exceeds the length of the
head. The depth at the front of the dorsal fin is one-third the length of the
caudal; the length of the head is one-fourth the same.

Sitzungsberichte Akad. Wiss. Wien, 1876, July (separata p. 25), Pl. VI.
This species, well described and figured by my friend Dr. Steindachner,
is too distinct from the species of Curimatus-to remain in that genus, in my
opinion. It presents between the ventral and anal fins not only a keel,
as in many species of the genus named, but the keel is surmounted by a
series of acute recurved spiniform scales, quite unlike the normally formed
ones which bound it in the keeled species of Curimatus. I therefore pro-
pose for it the generic name above written. The spinous processes are
stronger in my specimens than in the figure given by Dr. Steindachner.

Depth of body at dorsal fin entering the length less the caudal fin 3; times;
Length of head entering the same 3.7 times. Diameter of eye entering
head 4.5 times, or one and a half times in the muzzle and two and a half
times in the interorbital width. From these figures it is evident that this
isa moderately elongate species, with rather elongate and wide head. The
frontal region is convex, and the upper lip does not project beyond the
lower as in P. harttii Steind. The pectoral fins reach the ventrals, but
the latter fall far short of the anus. The belly between the latter and the
base of the ventral is keeled, but not serrate. The dorsal fin is situated a
little in advance of the ventrals, and is quite elevated, equaling the length
of the head. Caudal fin rather short and robust. Total length M. .200;
length of head .046 ; do. to base of dorsal (axial) .072 ; do. to ventral (axial)
.083 ; to base of anal .134; depth of caudal peduncle .020.
Color silvery, above shaded with blackish ; the scales at the base of the
anal fin inserted in a blackish skin. Dorsal fin with six or seven cross-
rows of blackish dots, which only mark the rays. Caudal fin with four
eross-bands of rather obscure character, which follow the posterior contour
of the fin, except the posterior, which cross the apices.

Two specimens from near Pebas resemble the species above named in all
points excepting in the more elongate body, so that I suspect them to repre-
sent a local race. There are 1.24 anal radii, and the longitudinal rows of
scales are 5—1+43-4. The total length without caudal fin is M. .034;
depth .013 ; length of head .0105. The caudal spot is very large, covering
the basal half of the fin, while the humeral spot is obsolete.

less the caudal fin 4.7 times, and the length of the head the same 4.2 times.
The diameter of the orbit enters the length of the head 3.5 times, and the
interorbital width 1.33 times. The maxillary bone is toothless, and rather
wide, and extends little beyond the line of the anterior border of the orbit.
The origin of the dorsal fin is behind the line of that of the ventrals, and is
nearer the origin of the caudal fin than the end of the muzzle by the length
of the latter.
There is a broad silvery lateral stripe, on which is a strong black hume-
ral spot. There is no distinct basal caudal spot. Total length .095.

94. SERRASALIMO IMMACULATUS sp. Nov.
This species belongs to the restricted genus Serrusuvlinv. There are six pre-
maxillary teeth, of which the third is much smaller than the others. Each
tooth has a denticle at its posterior base, which in the case of the external
tooth is longer horizontally than the principal cusp, and is not apiculate.
There are seven in the lower jaw, of sub-equal size, each with a posterior
basal denticle, except the anterior, which has two basal denticles.
The form is discoid, the depth entering the length less the caudal fin 1.8
times, and the length of the head entering the same three times. The
dorsal and ventral outlines are equally convex, but the steeper slopes are
opposite the anterior above, and the posterior below. Scales small 34-100-

apices. Diameter of eye entering length of head (ineluding chin) five
times ; and nearly twice in the interorbital space measured over its con-
vexity. The origin of the dorsal fin is above the ventral, and equi-distant
between the base of the superior marginal ray of the caudal fin and the pos-
terior border of the orbit. The superior caudal rays are not so long as the
inferior. Second sub-orbital bone as high as long. Muzzle a little longer
than diameter of orbit. The color is silvery without distinct spots ; in cer-
tain lights numerous small lead-colored spots may be detected on the dorsal
region, extending half way down to the lateral line. Caudal and anal fin
broadly black bordered; no yellow band. Total length M. .190; of head
059; to line of dorsal fin .090 ; to line of anal .116 ; to basis of marginal
caudal rays .161.
This species is near the 8. wsopus Cope, but is readily distinguished by

conspicuous cutting edge, as in Myletes. Two conical teeth behind the man -
dibular series. The belly is armed with spiniferous ? interheemal bones.
This form is related to Myletes precisely as Stethaprion is to Tetragonop-
terus. But one species is known to me.
Char. Specif. Form orbicular, the dorsal region very convex ; the ab-
dominal outline still more so. The depth is eleven-twelfths of the length less
the caudal fin, and the length of the head enters the latter three and two-
tenth times. The depth of the head from the superior border of the post-
temporal bone equals the length. The eye is large, entering the length of
the head three and one-sixth times, and the convex interorbital space one
and one-half times. The chin projects a little beyond the premaxillary
border, and the end of the toothless maxillary bone is immediately below
the proximal extremity and below the nostrils.
Radii; D. I. 17; A. 39; V. 7; P. 14. The ventral fins are very small,
and their base is contracted, so that the spines are arranged nearly in a
circle, the inner and outer being of equal length. The pectorals are small,
marking only the third of the distance to the line of the ventrals. The base
of the anal makes an angle of only 25° with the vertical ; its anterior rays are
little prolonged. The base of the dorsal is oblique downwards and back-
wards, and the first ray marks a point at .4, the distance between the bases
of the pectoral and ventral fins. The length of the base of the adipose dorsal
is two thirds that of the rayed dorsal. Ventral spines 25, the anterior re-
curved and simple, the posterior more or less bifurcate. The head of the
predorsal spine is anvil-shaped. The suborbital bones are narrow ; the an-
terior is the widest, and is triangular with the long apex superior.
Scales between the lateral line and the ventral fins, 39-40, those of the
lateral line (in front) larger than the others. Total length, M. .075; of
head, .020 ; to line of ventral fin, .033 ; of anal, .046 ; of caudal fin, 060.
First dorsal ray equidistant between base of caudal marginal ray and end

four teeth. The mandibular series is uninterrupted, and consists of seven
teeth on each side, the posterior four being much smaller than the others.
The two posterior mandibulars are incontact with the median pair of the
anterior series, and are separated by a narrow interspace from each other.
The general form is broadly rhombic. The depth is one-half the length
with the caudal fin, and the length of the head enters the same three and
one-half times. Radii; D. I. 15; A. 23; V.8; P. 16. The inferior paired
fins are very short; the others are well developed. The adipose fin is
furnished in its superior part with jointed rays, the inferior portion is
scaly. The base of the anal fin is covered with minute scales. The
origin of the first dorsal ray is a little behind that of the ventral fin,
and the anal begins under the last third of the former. Ventral spines
46, all simple and recurved. Scales 26—65+6—21 ; the lateral line con-
siderably decurved behind the head. The head is wide and depressed
above the orbits. The latter enter the length of the head 4.5 times;
the inter-orbital space 2.5 times, and the muzzle once, axially measured.
The frontal region is moderately convex in cross section. The mandibu-
lar teeth close within the premaxillaries, and the upper jaw projects be-
yond the mandible. The lips are equal, however, in consequence of the
thickness of the lower, which fills the space. Its superior surface is pap-
pillose, and at the points where it comes in contact with the maxillaries
it is continued as a free beard on each side, reaching to below the centre of
the nares when extended. The maxillary is folded under the preorbital,
but its posterior border cannot reach the line of the anterior border of the
orbit.
Total length. M. .130; of head, .040 ; to line of dorsal fin, .055 ; to line of
anal, .079; to base of caudal fin, .1038. Color silvery, plumbeous above ;
the sides marked with rather large round plumbeous spots. A silver band
on each side of the ventral spines. Anal fin, caudal, except superior and in-
ferior border, and terminal halves of paired fins, black. Dorsal dusky.
In alarger specimen, probably from Nauta (230 mm.), the scales are finely
ctenoid, those at the bases of the median fins coarsely so. The head is fur-
nished with minute rugosities, and there are no labial beards nor color
spots.

Dr. Steindachner in the Sitzungsberichte of the Vienna Academy for

the scales on the cheek. He finds my figure above cited to disagree with
my last description, in possession of three rows of cheek scales while I have
stated that only two exist. An examination of numerous specimens addi-
tional to those already in my possession, shows that they only exhibit two
rows of cheek scales as I have described. Dr. Steindachner has evidently
misunderstood my figure, for there are but two rows of cheek scales repre-
sented on it as described. The third row belongs to the inferior limb of the
peroperculum. The figure only is defective in the dark shading of the in-

rows. Form rather elongate; head not robust, its length entering the
total less the caudal fin 3.4 times. The depth at the ventral fin enters the
same 2.75 times. The preorbital bone is as wide antero-posteriorly as the
orbit, and exceed the interorbital space by 1 mm. The orbit is thus behind
the middle of the head, into whose length it enters 3.6 times. Its superior
rim is in the frontal plane. The fourth and longest dorsal spine is as long
as the cranium from the superior extremity of the branchial fissure to the
anterior border of the orbit. The profile descends from the supra-occipital
crest in a nearly straight line, with a slight concavity at the front of the
orbit.

Radii; D. XIII 19; A III 153. Scales 6—30-3—17-8 ; six rows on cheek.
The ventral fins commence under the third dorsal spine. The longest
(fourth) dorsal spine is equal to the diameter of the bony orbit, which
nearly equals the flat interorbital space. The preorbital bone is as long
antero-posteriorly as one-third the diameter of the orbit, which is one-third
the length of the head, exceeding a little the length of the muzzle. The
extremity of the maxillary bone extends a little beyond the line of the an-
terior border of the orbit.
The form is a moderately wide oval, with the profile from the base of the
dorsal fin a perfectly straight line to the end of the muzzle. The depth at
the ventral fins enters the length less the caudal 2.1 times, and the length
of the head enters the same 2.6times. Total length M. .095 ; of head, .027 ;

The single specimen in my possession is in rather bad condition. It is

The ventrals are cross-banded with deep brown; and anterior to them,
five similar bands, separated by silvery interspaces, cross the inferior sur-
face, the anterior three of which rise to the superior border of the inferior
ramus of the preoperculum. A brown horizontal line extends posteriorly
from the mouth.

The preceding families have all been known heretofore as occurring
in the fresh waters of South America, so that an analysis of the contents
of this catalogue must relate chiefly to the genera and species. In so
doing I first point out two genera which are characteristically marine, which
have been shown by Giinther and Steindachner to inhabit the Brazilian
Amazon. I have proven that their distribution extends even to the Pe-
ruvian Amazon, 2500 miles from the sea. They are :
I. Belone L. Tetrodon L., represented by one species each.
I next enumerate four species which are confined to the Alpine waters
of the Amazon, having been brought by Prof. Orton from the elevations of
from 10,000 to 11,400 feet. These are :
II. Arges sabalo, C. V.
Trichomycterus dispar Tsch.
Trichomycterus gracilis C. V.
Tetragonopterus tpanquianus Cope.
These represent the two families of Silurida and Characinida, which
are distributed everywhere in the neotropical realm. Of the Charaeci-
nide, Tetragonopterus is universally distributed. Of the Siluride, Arges
is Alpine, but whether found in the waters of the Pacific Slope as well
as the Atlantic, I am not informed. The other genus, Zrichomycterus,
is Alpine and West Coast, occurring from Equador to Southern Chili.
The two species enumerated above are the only ones from Atlantic
waters yet known. This is one of the few cases where a West Coast form
crosses the great watershed. It is well known that many genera are
common to the waters of both coasts, and even, according to Giinther, the
species Mucrodon trahira.

vian portion of its course. This list is obviously only provisional, as explo-
ration of the Amazonian basin has not progressed sufficiently to enable us
to assert the restricted distribution of any type. Thus the genus Otocin-
clus Cope, first obtained from the Peruvian Amazon, has been ascertained
by Steindachner to occur near Rio Janeiro. Zathorax and Triportheus first
determined from western species, occur on the Lower Amazon.+-The genera
remaining are :
Ill. Siluride ; Brochis Cope; Chenothorax Cope; Physopyxis Cope ;
Agamyzxis Cope ; Pariolius Cope.
Characinide ; Aphyocharawe Gthr.; Iguanodectes Cope; Stethaprion Cope.
Finally, the species which have not yet been found below the Peruvian
boundaries are as follows. I include species previously described by myself
from Pebas, in the essay on The Fishes of the Ambyiacu River,* also
those described by Gill from Orton’s first collection, and by Ginther from
those of Bartlett,

Char. Gen. A broad band of teeth on the premaxillary and dentary
bones, anda patch on the vomer. Dorsal spinous fin with four rays.
Ventral fins abdominal. Second dorsal opposite to anal. Dermal fold not
crossing superior portion of premaxillary region, hence the jaws are only
partially protractile.
This genus is an interesting form, probably of Mugilide, related to Pro-
tistius Cope, and Myaus Giinther. The wide bands of teeth, consisting
of numerous series, are not found in the last named genus, but belong to
the first. Here, however, the spinous dorsal fin is rudimental, and there are
no teeth on the vomer.
The pectoral fin has the elevated position usual in the Percesoces, but
the ventral fin is more posterior than in Mvgil, having the position usual
in Physostomous fishes. The spinous dorsal fin is very small, and the cau-
dal fin is forked, A lateral line of pores extends along the lower part of
the side.
The characters of this genus render it probable that Protistius* should
be referred to the Percesoces. These forms add to the number of existing
relationships between the cold blooded vertebrate faunse of Australia and
the West Coast of South America.

The muzzle is prominent and parabolic in outline, projecting very little

Besides the generic characters mentioned, this species differs from the
Protistius semotilus of the same region, in the larger number of soft rays, the
smaller eye, narrower interorbital space, etc. The lateral line is better de-
fined in this species, but is not continued beyond the anal fin; a few iso-

The color of the Gastropterus urcheus is silvery, darker shaded on the
upper surfaces, and without spots on the body or fins.

Radiation and Rotation.
By PLiny EARLE CHassz, LL.D.,
PROFESSOR OF PHILOSOPHY IN HAVERFORD COLLEGE.
(Read before the American Philosophical Society, June 21, 1878.)
Among the most interesting of the unsolved astronomical problems, are
the questions as to the origin of solar radiation and of cosmical rotation.
These two problems, as I have already shown, are intimately connected,
at the centre of our system, by the ultimate equality which exists between
the velocity of light, the limiting centrifugal velocity of solar rotation, and
the velocity of complete solar dissociation.
It has been commonly assumed that physical forces tend to ultimate equi-
librium and consequent complete stagnation. The imperfections of any
plan which looks to such a final result, have led some writers to suppose
that there may be some compensating provisions, hitherto undiscovered, for
a renewal of activity. In the search for such provisions, the equality of
action and reaction and the possibility that the compensation is continually
furnished, by Him who is ever ‘‘upholding all things by the word of His
power,’’ seem to have been wholly overlooked.
If we assume the existeace of a luminiferous ether, whether as a reality, or
as a convenient representative of co-ordinated central forces, its undulations,
when obstructed by inert centres, would necessarily lead tosuch phenomena
as those of gravitation, light, heat, electricity, magnetism, etc. Confining
ourselves for the present to the action of gravitation, it is well known that
the limiting velocity of possible gravitating action and consequent cen-
trifugal reaction, at any given point, isy2 gr, the velocity varying as ;

ing nucleus, should vary as But according to Graham’s law, » «

real elasticity, within any nucleus which is either wholly or almost wholly
gaseous, OC —_-
Since such is the supposed character of the solar nucleus, it seems not
unlikely that the centrifugal radiations of any heavenly body being at all
times equivalent to the centripetal radiations which it intercepts, solar and
stellar light and heat are only the reactionary consequences, of such per-
petual internal oscillations as the ether has first transmitted to the luminous
orbs and then resumed. The fact that the reaction, which is shown in the
centrifugal force of solar rotation, and the action which is shown in para-
bolic orbital velocities, find a common limit in the velocity of light, may
perhaps be regarded as a crucial test of this hypothesis, which is pares
strengthened by the following considerations.
In the huge comet-like nebulosity which is indicated by the solar-stellar
paraboloid, the interesting relation which has been pointed out by Stockwell, *
between the perihelia of Jupiter and Uranus, and the many indications of
normal ‘‘subsidence,’’ which I have shown in previous papers, suggest the
probability of an early ellipsoidal nucleus, witb subordinate nucleoli ; the
major axis of the. nucleus being bounded by 2 VY; (60.939) and 2 6, (41.-
358), and the Sun being in the focus. The vis vivu of condensation. would

ondary system (¢', + $, +-2=1. jek 4
If we apply Gummere’s criterion (7 = 11.656854), we find that three
prominent centres of ‘‘ subsidence ’’ were determined by this early ellipsoid-
al nucleus. For 2 UW, + = 5.228, 2/, being 5.203; 2 6, > n=

(WY, — 4,) + m= 1.022, the centre of the secondary system being, as
above stated, 1.017. The Earth is still in the centre of a ‘‘subsidence”’
ellipsoid, of which the sun is in one focus, while the outer asteroidal region
(3.2028) and 2/, (5.2028) are at opposite apsidal extremities of the major
axis. Moreover, 3.2035 is the extremity of an atmospherical radius which
would move with the velocity of light, provided the sun’s surface were
moving with orbital velocity, or the velocity of incipient dissociation (V gr).
It seems probable that in consequence of subsidence, Jupiter, which, as
we have already seen, was the centre of nucleal volume, may have been also
the centre of nucleal mass, at the time of its complete orbital separation and
that it was, therefore, the primitive Sun of the extra-asteroidal planets,
before it became our Sun's ‘‘companion-star.’’ For with the present mass of

the system, and with a mean radius vector = WV, + 2/, (34.4845), the
orbital period of Neptune would be 73966 days. Two successive subsi- .
dences (34.4845 = n*) would bring the solar nucleal surface to about 3 of
%., or 54.53 solar radii. The angular acceleration of rotation, due to sub-
sequent nucleal contraction, would « Therefore, when the Sun had

= 24.88 days.*
If this were the only coincidence of its kind we might, perhaps, have
some good grounds for looking upon it as merely curious and accidental,
But the bond of connection, which we have already found between rota-
tion and revolution, in the limiting formative undulations which are prop-
agated with the velocity of light, may prepare us for accepting evidences
of a similar bond in the phenomena of nebular subsidence.
There are three other known systems of cosmical rotation, which may
help us to judge as to the rightfulness of such an acceptance, viz.: that of
the extra-asteroidal planets, with an estimated average period of about 10
hours ; that of the intra-asteroidal planets, with an estimated period of
about 24 hours, and that of the moon, with a synodic period of 29.5306
days. If these periods are dependent upon the same subsidence which
led to the early belt formations, we may reasonably look for evidence of
that dependence of a character similar to that which we have found in the
case of the sun.
We have seen that the first subsidences from 2 UV and 2 2/, account for
the orbital ruptures of Jupiter and the Earth ; secondary subsidences from
points within the orbital belts, account for these three rotation periods.
For 2/, = 2 = 101.73 solar radiiand Jupiter’s orbital revolution (4332.585
dy.) = 101. 73? = 10h.05 ; ©, + m = 19.66 solar radii and Earth’s orbital
revolution (366.256 dy.) -- 19.66? = 24h.205; ),+ m= 5.442 Earth’s
radii and Earth’s rotation K 5.4427 = 29.619 dy. In these accordances we
have additional evidence of the equality of action and reaction.
The normal character of rotation is still further traceable, even after the
formation of the subordinate planets if the two principal planetary belts.
If we seek the point of incipient condensation, which would lead to such
rotation periods as have been generally assigned by astronomers to the
different planets, we readily find that Gummere’s criterion, Newton’s third
a eg
law, and the law of equal areas, lead to the formula 7 (.)'= in
“These relations may have an important bearing on Croll’s hypothesis of
the origin of solar radiation. In the stellar-solar paraboloid, of which traces still
exist between Sun and «@ Centauri, there must have been frequent collisions.
Some of Croll’s critics have shown strange misapprehensions as to the possible
velocity of collision. The limit of possible relative velocity, from the simple
gravitation of two equal meeting masses, is 2 ;/ 2gr. This would be equivalent,
taking the values of g andr at Sun’s apparent surface, to .017747, or more than
750 miles per second. If projection were added to gravitation, or if the two
masses had small solid nuclei of great density, while the greater part of their
volume was gaseous, or if there were a large number of equal masses, the limit
of possible velocity might be largely increased.

Letter of Dr. Alexander Wilcocks on Shadows Without Penumbra, read
February 1, 1878.
EVAN HALL, NEAR DONALDSONVILLE, LOUISIANA, )
26th January, 1878.
To the Secretaries oft the American Philosophical Society.
I have within the last few days witnessed a phenomenon which I[ had
diligently looked for in vain for more than forty years, viz.: The Produc-
tion of a Shadow by the light of a Planet.
The body which occasioned the shadow was the planet Venus, and the
circumstances under which it was seen were exceptionally favorable.
The Sun having been below the horizon an hour and a half; the Moon
not haying risen ; the atmosphere being very clear, and the planet shining
brightly in the south-west, I was passing along a white wall which faced
in that direction, and saw distinctly my shadow moving upon the wall.
There are some particulars in which a shadow produced by a planet
should differ from the shadows caused by the other celestial luminaries.
To our unassisted vision the planets practically occupy mere points in the
heavens (their apparent diameters being only an optical illusion).
The Sun and Moon having each of them a diameter which occupies
about half a degree of space in the celestial hemisphere, the shadows
thrown by these luminaries can never be sharp and well defined. Every
such shadow must have a penumbra.
Now in the shadows produced by Venus there is no penumbra. The
shadow of a hand distant twelve feet from the wall I found perfectly sharp
and well defined ; and more striking still, the shadows of the twigs of a
Pecan tree distant fifty yards were also sharp. These last shadows were
faint from the effect of the diffused light from the sky, which illumined
the wall.
When in sunlight two objects are made to approach each other, there
appears between their shadows a dark process which connects the two
before the bodies actually come together.
In the shadows produced by Venus nothing of the kind takes place.
In sunlight a man’s finger held twelve feet from a screen has a shadow
consisting entirely of penumbra. The umbra has vanished.
The shadows produced by Venus are exclusively umbra.
The above observations and reflections may have been made by others ; if
s0,they have not fallen under my notice.
P. §.—A few daws after the above remarks were penned, when the new
moon was beginning to throw visible shadows, I had an opportunity to
compare the strength of these with those produced by Venus.
The shadows caused by the primary planet were sharper and stronger
than those thrown by our satellite.
Very Respectfully yours,
ALEXANDER WILCOCKS.

I. A new Monochlordinitrophenol and an Aniline derivative of a-Mono-
chlordinitrophenol. II. Beryllium Borate.
By Epear F. Smrra.
(Read before the American Philosophical Society, June 21, 1878.)
When fuming nitric acid is allowed to act upon pure monochlorsalicylic
acid, there is produced not only the corresponding monochlornitrosalicylic
acid (in small quantities), but the nitration usually extends so far as to
cause the carboxyl group to disappear, and two nitro-groups enter, leav-
ing us a monochlordinitrophenol. The formation of this latter compound
was first effected in this manner by Rogers (Inaugural Dissertation, Got-
tingen, 1875). The phenol showed a constant fusing point of 79°-80°C.,
was rather insoluble in cold water, more readily soluble in warm, and crys-
tallized from its aqueous solutions in long yellow needles.
The salts of this acid are very beautiful, but it will suffice for our pur-
pose to mention only the potassium derivative, which separates from its
solutions in long, beautiful silky-red needles, without any water of crys-
tallization.
The above phenol and its potassium salt I also produced, but, after work-
ing with the latter for some time, I suspected the presence of another com-
pound, and by repeated re-crystallization from aqueous solutions I finally
obtained not only the red potassium salt, but a similar compound which sepa-
rated in large bundles consisting of orange-colored needles. These, after
being completely separated from the red salt, were subjected to an analy-
sis to ascertain their constitution.
Analysis of the red colored salt.
.1691 grms. salt, dried at 130° C., were placed in a platinum crucible, a
few drops of conc. sulphuric acid added, and a gentle heat applied. The
K,SO, that remained = .0264 grms., which corresponded to 15,60%
potassium. The salt is anhydrous. The calculated percentage of K in
C,H,Cl (NO,),OK is 15.28%. There was, therefore, no doubt as to the
constitution of this salt.
MONOCHLORDINITROPHENOL.
Fusing point 80° C.
The free acid crystallized from aqueous solutions in long yellow needles,
which fused at 80°C and solidified again at 69°C. It is also identical with
the phenol of Rogers (see above) and the a-Chlordinitrophenol of Faust
and Saame (Annalen der Chemie u. Pharmacie, 1870. 7 Supplement-
band. 2 Heft 8. 174).

Analysis of the yellow colored salt.
Water Determination.—.1617 grms. air dried salt lost upon heating at
140° for four hours .0168 grms. H,O = 10.39%. 14 mols H,O require
9.53%.
Potassium Determination.—.1449 grms. substance gave, upon evapora-
tion with sulphuric acid, .0480 grms. K,SO, = 14.86% potassium. From
this we see that this salt is also a derivative of a monochlordinitrophenol.
The formula is C, H, Cl(NO,), OK + 13 H,0.
This salt is much more soluble than the red compound. The color of
the latter is so intense as to entirely obscure the yellow, which conse-
quently is overlooked unless great care is exercised in re-crystallizing the
red compound,
MoNOCHLORDINITROPHENOL.
Fusing point 79°-80°C,
Upon mixing a cold solution of the yellow salt with dilute nitric acid the
corresponding phenol separated in yellowish colored masses, which upon
being washed and re-crystallized several times from aqueous solutions,
separated in rather long lemon-yellow colored needles. The fusing point
of this compound remained constant at 79°-80°C. The point of solidifica-
tion was 25°C., considerably lower than that of the acid corresponding to
the red needles. In cold water the acid is rather insoluble, readily dis-
solved on heating. ;
Another difference noticed between the free acid from the red silky
needles, and that just above described is. in the silver salts. The former
yields a soluble salt crystallizing in long bright red colored needles, the
latter one separates out in bronze colored needles which possess a marked
metallic lustre.
This new Chlordinitrophenol is usually formed in very small quantities,
therefore I have not beenable to subject it to as thorough an investigation as
I desired. The material with which I worked was, however, perfectly
pure, and as I have obtained the compound at various times, and the
analytical results being the same on all occasions, I do not hesitate to
announce the above acid as another of the many possible compounds hav-
ing this composition. In regard to the position of the (NO,) groups I can-
not as yet give any definite information.
a- MONOCHLORDINITROPHENOL-ANILINE.
A small quantity of a-Chlordinitrophenol was mixed with sufficient
aniline to dissolve the former in the cold. As soon as the two compounds
were brought in contact the solution assumed a beautiful red color, which
imparts to the skin a rather difficultly removable yellow stain. The solu-
tion was gently warmed on a water bath for ten minutes, and the liquid
then poured from the flask containing it into a rather large watch glass and
allowed to cool. Upon cooling there separated hard nodular crystals,
which were pressed well between paper and dried by exposure to the air,
Smith.] 708 [June 21, 1878.
then dissolved in warm water, from which, on cooling, long curled light-
yellow needles separated. The fusing point of this compound after
repeated re-crystallizations remained constant at 187°C. When solutions
of the compound in water are boiled hard aniline separates out. An analy-
sis of the substance indicated it to be a union of one mol. chlordinitro-
phenol with a like amount of aniline—C, H, Cl (NO,), CH. C, H; NH,.
Analysis. —.1221 grms dried substance burned with lead chromate gave
.0188 grms. Carbon = 46.19% C. The hydrogen determination was lost.
The theoretical percentage of carbon demanded by the above compound is
46.22 %C.

BERYLLIUM BORATE.
Some time ago I was working with beryllium and added to a solution of
its chloride an excess of a rather concentrated borax solution. An imme-
diate precipitation was the result. The precipitate was thrown upon a fil-
ter and washed with hot water, until a drop of the washings evaporated
upon platinum foil left no residue.
The precipitate was dried and tested for boracic acid, but this was not
found present. Another portion of the same precipitate subjected to an
analysis proved it to be nothing more than beryllium hydrate, consequently
if the borate had been at first produced, the subsequent boiling with hot
water had decomposed it.
Another portion of the beryllium chloride was treated in a similar man-
ner. The precipitate was brought on the filter to allow the liquid to drain
oft, and then rinsed with cold water into a small flask, water added, and
allowed to stand for some time—being occasionally shaken. The precipi-
tate was then brought on to a filter and dried by exposure to the air.
Boracic acid was found present when the tests were made.
Analysis gave me the following percentages of beryllium oxide: 6.98
BeO and 6.89 %BeO.
The boracic acid was not estimated.

Mr. Britton called attentien tothe forms in which Carbon
existed in iron and steel.
He referred to the two well-known, the combined and graphitic, and
also to a third form or semi-graphitic. The latter he had found in poorly
puddled metal, and also in Siemens-Martin steel, and more recently in Bes-
semer steel rails that had not given satisfaction, and in some pig iron pro-
duced when the furnace was working abnormally. The semi-graphitic
form could be separated and collected by treating the metal containing it
with dilute sulphuric or hydrochloric acid without the application of much
heat until all the iron became dissolved, and then filtering the solution ; it
would be on the filter, but in appearance not so black as the graphitic ;
would have a reddish tinge, that, upon ignition would leave the ash of the
paper white. By boiling from ten to thirty minutes all of it appears to dis-
solve. Mr. Britton illustrated the behavior of this third form of carbon by
producing several glass tubes, in some of which it was not dissolved in the
acids mentioned, and in others scarcely any of it was observable after being
boiled for twenty minutes. The existence of more than two forms of carbon

in iron and steel was observed by him several years ago, but he believed
that it was not generally credited. It was a source of error in determining
carbon by the colorimetric method. He proposed to make further investi-
gation by analyses, and to communicate his results.
The Committee on the Michaux Legacy reported that they
had purchased and presented to the Fairmount Park Com-
mission, for Horticultural Library, the North American

“A detailed section of the rocks included between the lower
productive coal measures and the dark shales of the De-
vonian, in the vicinity of Renova, Clinton Co., Pa., by H.
M. Chance, of the Geological Survey of Pennsylvania.”
The Secretary read portions of a letter from Mr. W. D.
H. Mason, Williamstown, Pa., describing the circumstances
of his recent discovery of reptilian footprints on a slab of
slate rock from the shaft of the Ellengowan Colliery, over-
lying the mammoth anthracite coal bed, in the Mahanoy
Valley, Schuylkill Co., Pa., the original being in the posses-
sion of Mr. Lorenz of the Reading R. R., to be deposited
in the museum of the Academy of Natural Sciences.
Letler of Mr. Wm. D. H. Mason, C. E., of Williamstown, Dauphin County,
Pennsylvania, on the Batrachian Foot-trucks from the Ellengowan Shaft
in Schuylkill County, Dated April 5, 1878.
As an additional link added to knowledge in the mystery attending the
process of creation going on during the coal formation, in which geologists
have heretofore been almost unanimous in doubting the existence of higher
animal life, the finding of the singularly clear fossil Batrachian foot-marks
imprinted on the gray slaty sandstone overlying the mammoth seam of
CLT
coal, which have for some time past been exhibited in the office of W.
Lorenz, Esq., Chief Engineer of the Philadelphia and Reading Railroad
Company, were placed in his care for critical examination by those inter-
ested in such discoveries, previeus to being presented by Mr. Lorenz, on
my behalf, to the Academy of Natural Sciences at Philadelphia.
These foot-marks might easily be mistaken by people in general for those
made by a small bird, on account of the three toes on the front and one at
the back part of the foot with the joints and curved nails or claws, which
are distinctly shown by their deeper indentations on the stone. The
cushion-like ball of the foot aids the deception ; but the regular alternation
of frontand hind, right and left feet, each on their own line, as made by
four-footed animals of the kind, dispels the idea of a biped.
These foot-prints were found on the 15th of June, 1876, at Ellangowan
colliery, owned and operated by the Philadelphia and Reading Coal and
Tron Company, situated in E. Mahanoy Township, Schuylkill Co., Pa.,
about midway between Mahanoy City and Shenandoah, in a small valley
diverging from the Mahanoy valley proper. In tiis valley a split of the
mammoth seam occurs which can best be explained by the mining en-
gineers of the C. & I. Co., who have access to the maps and mines with
all their secrets, splittings and ramifications, together with all the pecu-
liarities, depth and thickness of rock and coal seams at that point.
Inquiry, at the time, of the bosses of the colliery, elicited the bare in-
formation that the rocks amongst which the specimen was found, had been
taken from the shaft while it was being sunk and overlaid the mammoth ;
but they could give nothing definite as to depth below the surface, or posi-
tion. My own impression is, that it was taken from the upper and most
shelly or shale-like portion of this stratum of slate ; this opinion being based
upon the fact that the most noticeable peculiarities exist mainly in its upper
portion. Of these peculiarities, the frequent occurrence of nodules of
hematitic iron and occasional ripple marks are the most, prominent. In
fact, it was by the observation of these characteristics that I was led to
search among the rocks lying around, that the footmarks were found, and,
if not destroyed by the burning of the breaker last fall, the other portions
of the same rock still remain there. The piece bearing the marks was
much larger than it now is and was trimmed down, for convenience in car-
riage, though the foot-marks were all preserved and all I cared for.
It had been lying under the eaves of a shed, subjected to the dripping of
water therefrom for several years, and close to the path leading around the
shed, and by which path the mules were driven when used at the breaker.
Only a portion of one foot was first visible, but by carefully removing thin
films or scales of slate, the others were brought out. So cautiously did I
work, that the impressions on the upper scales were destroyed, because too
thin, and the danger of injuring those on the body of the stone. The fear
of injury was so strong, that I only felt sure of my prize when it was
safely deposited in my room at the hotel. Habitual search for fossils when
about a rock bank of a coal mine, or where slates and shales present any in-
718
dication of fossil remains, led me to search around on the occasion of this
find which solves so knotty a problem.
The frequent occurrence of nodules of iron in different rocks, shales, or
argillaceous deposits, I have never seen ascribed by any writer I have had
access to, to any cause other than the accidental collection of ferruginous
matter by molecular attraction; but in the center of such nodules, some
definite shape is often found ; sometimes a leaf, an insect or only a grain of
sand ; or, the interior cavity may be filled with ocherous or argillaceous
matter.
In the old red sandstone, fossilized fish and plants most frequently show
a casing or thin cover of a strongly ferruginous nature, which decreases in
strength with increased distance from the center of the cast in the same
ratio as one color is blended into another by the artist.
In the slates and fine sandstones where nodules appear, they either have
a cavity of loose, ocherous matter—a pyritous speck ora mass of small,
strongly sulphurous pyrites in crystals—sometimes only a grain of sand;
and in the coarser sandstones between the coal seams, the plants exposed
on their surface present a dark brown appearance, which shows a red
streak when the film is thick enough to bear scratching.
Balls found in the slates and fine sandstones vary in shape as they do in
size, from a perfect sphere, to irregular oblongs of every imaginable form.
Now, taking the abundance of fossil fish and other organic remains found
in some portions of the old red sandstone, may we not reasonably suppose
that the gray, slaty sandstone, overlying the mammoth coal seam, lying
low down in our anthracite coal measure, has, in like manner been a re-
ceptacle for the remains of animal life ; although these remains present to
the eye more of the appearance and form of potatoes than animal. remains ?
Is it not possible that by partial decomposition and chemical action upon
their tissues and bones, they were converted into a pulpy or gelatinous sub-
stance which, by the action of the water in which they were floated or by
the joint attrition of water and fine mud into which their bodies were
borne, these jelly-like remains were rolled out of all semblance to their
original organic shape, and then, by the strange chemistry of the period,
became each a nucleus to which were attracted the minute particles of iron
converting their remains into the substances and shapes they now bear?
These thoughts suggested themselves at various times before the finding
of the tracks in the same bed by the singularly animal-like shape of some
of the nodules previously met with. ‘‘ Accidental’ shapes they may have
been, as I could find no trace of tooth, claw, or bone of any kind, yet this
does not discourage me from holding to the firm belief, amounting almost
to conviction, that such discoveries will be made, and by the calling of
attention to this point by men of acknowledged scientific character, others
may be led to examine more closely these singularly sown nodules and
yet more conclusively than these few tracks, establish beyond dispute the
existence of animal life in abundance during the period of the formation of
coal.

The tunnel driven through Big Lick Mountain, at the Summit Branch
Colliery at this place (Williamstown), furnished me at one time with a
specimen of more interest, if possible, than the saurian foot-marks from the
Mahanoy Valley, being no less than a sandstone cast of the head of the
thigh bone of some animal that had evidently been of large size, the cast
having been over four inches in diameter, and nearly ten pounds in weight.
It was presented to me by Mr. Daniel James, the foreman of the gangs of
men driving the tunnel from the south side. He could not find a trace of
the other portion, as it had been thrown out by a blast, although he
searched carefully. In appearance the cast had a striking similarity to the
head of the femur in a human skeleton and was almost perfect, owing to
its great hardness and the hard character of the surrounding rock, some
of which clung to it most tenaciously and could not safely be removed by
hammer and chisel. Unfortunately it went astray by getting into the
hands of some unprincipled individual during transmission to the Society
of Natural Sciences at Reading, to which my design was to present it, and
only the memory remains.
This most interesting cast was from a ‘‘slip,’* in excessively hard rock
lying north of what is here known as the ‘‘ Whites’’ vein or seam of coal,
hundreds of feet beneath the mammoth, but overlying the Lykens Valley
seam. As I preserved no record or drawing of this find, it is only by a
draft upon memory to give an indistinct idea of it in a rude drawing as
this eee Xx
The cast was a fine-grained, very compact sandstone, wholly different
in texture and color from the surrounding rock of the ‘‘slip,’’ which was
over a hundred feet beneath the surface of the mountain and several hun-
dred yards from the southern opening of the tunnel, so that, without an
opening to the surface, which there was not, it could not reasonably be
suspected to have been the remains of an animal dropped in from the sur-
face. This was in the summer of 1872, but the impression it then created
was very strong and its appearance still remains vivid in memory.
Respectfully, &c.,
WM. D. H. MASON.
WILLIAMSTOWN, Daupuin Co., April 4, 1878.
Prof. Prime exhibited photograph pictures of limestone
(Siluro-cambrian) outcrops along the west bank of the Le-
high River above Allentown, which evidently verify Prof.
Rogers’ hypothesis of the cause of the general south-east
dips which prevail through the Great Valley. In these pic-
- tures a number of local sharp overthrown anticlinal rolls or
saddles are beautifully exhibited.
Prof. Frazer remarked that he had just completed his
Susquehanna river section in Lancaster County, through
720
the same limestone formation, and was surprised to find evi-
dence in its construction, of very broad and regular anticlinals
with opposite dips; the whole limestone series measuring
more than 3000 feet; a measurement corresponding very
well with that of the limestones in York Co.
Pref. Prime said that he could not obtain more than 2000
feet of limestones in the Lehigh region.
Prof. Houston described some improvements which he and

of the Argentine Republic at the Centennial Exhibition of
1876.
The death of Prof. Joseph Henry, Secretary of the Smith-
sonian Institution, at Washington, May 13th, 1878, aged 81
years, was announced with appropriate remarks by Mr.
Fraley.
Mr. Roberts added his reminiscences of Mr. Henry at the
meeting of the British Association at Liverpool, in 1887,
and described a characteristic scene between him and Dr.
Dio. Lardner, and the cordial reception of Mr. Henry, by
the distinguished members of the Association then present;
the commencement of many warm and lasting and honor-
able friendships.
On motion Mr. Fairman Rogers was appointed to prepare
an obituary notice of the deceased.
The death of Mr. Robert Frazer, at Philadelphia, May
4th, 1878, aged years, was announced by the Secretary.
On motion Mr. Persifor Frazer, Jr., was appointed to read
an obituary notice of the deceased.
A letter to the Secretary respecting an extract from a pa-
per on Gas Analysis, by Prof. Sadtler, published in the Pro-
ceedings under date of April 6th, 1878, was received from
Prof. Henry Morton, dated Hoboken, N. J.
May 15, 1878.
To the Secretary American Philosophical Society.
Dear Srr :—In a printed copy of a paper ‘‘ On the calculation of Results
in Gas-Analyses,’’ read betore the American Philosophical Society, April
5, 1878, by Professor Samuel P. Sadtler, which I have just received, I find
the following statement :
‘‘In a private letter to Professor Morton, dated December 81st last, in
answer to one received from him a day or two before, calling my attention
to the error, [ acknowledged the error of the formula used by me in my
printed paper, and mentioned that I was proposing to rectify the result as
first published by the aid of other tests.’’
723
Professor Sadtler is here no doubt quoting from memory, and does not
intend to state what is not true, but as the statement is not only incorrect,
but by reason of its inaccuracy casts a reflection upon me, I feel bound to
call for a correction. Professor Sadtler’s letter of December 31st is now
before me, and the only passage having any reference to the matter reads
as follows :
*“About the formule, I am sorry that my first mistake still stands on
record uncorrected. I had copied the formule I first used from Foucou’s
article on analyses of ‘Pennsylvania Natural Gases’ in Comptes Rendus,
and in my second lot of analyses made for the Survey, I corrected it, and
corrected the first lot at the same time.’’ This includes every word which
this letter contains on the matter referred to, and while it may be that Pro-
fessor Sadtler at the time of writing knew all about the matter, there was
certainly nothing whatever to imply that such was the case in what he
here states. On the contrary, when it is known that Foucou’s article, in the
Comptes Rendus referred to, contains no formule whatever, and that no
correction of analyses was possible for the simple reason that the correction
of the error showed any analysis to be impossible except by discovering a
new method, it will appear that I had good cause to believe that Professor
Sadtler was entirely in the dark upon the subject.
As to the assertion that he said in this letter ‘‘that (he) I was proposing
to rectify the results as first published by the aid of other tests,’’ it is
simply a lapse of memory on his part, as nothing of the sort exists in the
letter.
In a memoir by Fouqué (not Foucou), immediately following that of
Foucou in the Comptes Rendus, we do find formule in some sort resembling
those used by Professor Sadtler, but mot containing his error. Fouqué’s
formule are in fact perfectly correct, and so are his results, his only fault
lay in failing to perceive, that hydrogen might be regarded as a lower
member of the marsh-gas series,* and thus find a place in his general
equation.
Yours respectfully,
HENRY MORTON.
Prof. Sadtler, to whom the letter had been shown previous
to the meeting, read a written reply to Prof. Morton’s state-
ments.
In the letter from Professor Morton just read before the Society, he
quotes from my paper read here on April 5th, the paragraph relating to the
correspondence which passed between us about December 31st last, and
supposes that I was quoting from memory. This is certainly true. I had
not copied the letter, as it was regarded by me so entirely one of friendly
correspondence, that I deemed such a step unnecessary. My reco‘lec.ioa of
* As was first pointed cut by Mr. Wm. E. Geyerand myself in our paper in the
Gas-Light Journal, February 16th.
724
my words must therefore have been an incorrect one when I supposed that
with my acknowledgment of the error I mentioned the test proposed by me
in September last here before the Society. I certainly have been under the
impression that I alluded to them in writing to him at that time. In this
point then, I have done Professor Morton an injustice. I must still rely on
my recollection of what I wrote in that letter, but I do not think I alluded
to Foucou’s article at all in writing to him. I think, if Professor Morton
would look at my letter again, he will see that I alluded to Fouqué’s
article. It would have been absurd for me to have appealed to
Foucou’s article as that was a geological one, and dealt only with the
matter of the occurrence of these natural gases. The article of Fouqué,
which follows it in the Comptes Rendus, on the other hand speaks of the .
analysis of these gases, and gives equations for such analysis. So what Pro-
fessor Morton says in italics, viz.: that the article of Foucou referred to
‘‘contained no formule whatever,’’ is true, but has no bearing upon the
question at issue. I have alluded in every paper which I have published
on this matter, including those in Professor Morton’s hands at the time of
his first writing, to Fouqué’s formulas and his article, found in Comptes
Rendus, Vol. 87, p. 1048, and not to Foucou’s article, found just before it
on page 1041. In my last paper, read here on April 5th, I quote Fouqué’s
lauguage on the subject just as it appears in the original French, and 1
think the words are capable of but one interpretation, viz.: that which I
gave them. That Fouqué was in error, and that I fell originally into the
same error, does not make me guilty of a willful prevarication in this matter
of quoting Fouqué. ’
Professor Morton says that ‘‘ Fouqué’s formule are in fact perfectly cor-
rect, and so are his results, his only fault lay in failing to perceive that
hydrogen might be regarded as a lower member of the marsh-gas series,
and thus find a place in his general equation.”’
Professor Morton, in calling attention to my “errors, seems to me to be
willing to let Fouqué off much too easily. His fault is greater than that
here indicated. Fouqué literally translated says, ‘‘a mixture of these car-
bides with free hydrogen prevents this condition from being realized. It is
therefore easy to recognize if a mixture of gaseous hydrocarbons consist ex-
clusively of carbides of the formula Cn H2n + 2,”? He therefore not only
‘‘ fails to perceive that hydrogen might be regarded as a lower member of
the marsh-gas series,’’ to use Professor Morton’s words, but says distinctly
that its presence interferes with the realization of an equation character-
istic of the marsh-gas hydrocarbons as a series.
I have no desire to shield myself behind Fouqué’s faults, but I wish to
be given credit for a faithful interpretation of his language, and for a wil-
lingness to acknowledge my errors wlren they are pointed out.
The Secretary exhibited by permission of Mr. Lorenz,
Chief Engineer of the Reading R. R., the stone slab from
the Ellengowan Colliery shaft, bearing the Batrachian foot-
725
prints mentioned at the last meeting, and referred again to
the letter of Mr. Mason, its discoverer. Mr. Lesley stated
that he understood Mr. Lorenz to wish to propose for it
the name Anthracopes Masoni, provisionally, until the dis-
covery of other foot-prints or remains of the animal, should
give occasion for a better determination of genus or species.
Mr. Frazer exhibited what is perhaps the first perfectly
successful electrotype of a piece of a phonograph ribbon,
made by Mr. Edison.
Mr. Frazer described ripple-marks on a slab of limestone
from the Siluro-Cambrian region of Lancaster county, and
Prof. Prim added that such ripple-marks entirely cover the
exposed surfaces in the Euhlersville Quarry, in Northampton
County ; these beds being also of Calciferus sandstone age.
Mr. Frazer then drew attention to the great significance
and geological importance of his recent discovery of an im-
mense anticlinal, crossing Lancaster county, and probably
traversing York county into Maryland. He called it the
“Martic” anticlinal, and showed how it exposed fundamental
gneiss and granitoid beds in the new railroad cuttings along
the left bank of the Susquehanna river ; how it sheds off to
the north and to the south at least 16,000 feet of primal
(Cambrian?) slates ; and how its eastern prolongation, would
cross Lancaster country into Chester county, where the
uplift seems to be represented by the fundamental gneiss
series of the Welsh Mountain.
The minutes of the last meeting of the Board of Officers
and Council were read.
Pending nominations Nos. 857 to 863, and new nomina-
tions Nos. 864 to 869 were read.
Prof. Cope called up his motion of April 5th, which after
discussion, was, on motion of Mr. Lesley, indefinitely post-
poned.
And the meeting was adjourned.
