CONSTITUTION.
ARTICLE Tf.
Section 1. This association shall be called the Indiana Academy
of Science.
Src. 2. The objects of this Academy shall be scientific research
and the diffusion of knowledge concerning the various departments of
science; to promote intercourse between men engaged in scientific work,
especially in Indiana; to assist by investigation and discussion in devel-
oping and making known the material, educational and other resources
and riches of the State; to arrange and prepare for publication such
reports of investigation and discussions as may further the aims and
objects of the Academy as set forth in these articles.
Whereas, the State has undertaken the publication of such proceed-
ings, the Academy will, upon request of the Governor, or of one of
the several departments of the State, through the Governor, act through
its council as an advisory body in the direction and execution of any
investigation within its province as stated. The necessary expenses
incurred in the prosecution of such investigation are to be borne by
the State; no pecuniary gain is to come to the Academy for its advice
or direction of such investigation.
The regular proceedings of the Academy as published by the State
shall become a public document.
ARTICLE II.

Non-resident members may be elected from those who have been active
members but who have removed from the State. In any case, a three-
fourths vote of the members present shall elect to membership. Appli-
cations for membership in any of the foregoing classes shall be referred
to a committee on application for membership, who shall consider such
application and report to the Academy before the election.
Sec. 3. The members who are actively engaged in scientific work,
who have recognized standing as scientific men, and who have been
members of the Academy at least one year, may be recommended for
nomination for election as fellows by three fellows or members per-
sonally acquainted with their work and character. Of members so
nominated a number not exceeding five in one year May, on recom-
mendation of the Executive Committee, be elected as fellows. At the
meeting at which this is adopted, the members of the Executive Com-
mittee for 1894 and fifteen others shall be elected fellows, and those
now honorary members shall become honorary fellows. Honorary fel-
lows may be elected on account of special prominence in science. on
the written recommendation of two members of the Academy. In
any case a three-fourths vote of the members present shall elect.
ARTICLE III.
Section 1. The officers of this Academy shall be chosen by ballot
at the annual meeting, and shall hold office one year. They shall
consist of a President, Vice-President, Secretary, Assistant Secretary,
Press Secretary, and Treasurer, who shall perform the duties usually
pertaining to their respective offices and in addition, with the ex-Presi-
dents of the Academy, shall constitute an Executive Committee. The
President shall, at each annual meeting, appoint two members to be
a committee which shall prepare the programs and have charge of the
arrangements for all meetings for one year.
Sec. 2. The annual meeting of this Academy shall be held in the
city of Indianapolis within the week following Christmas of each year,
unless otherwise ordered by the Executive Committee. There shall
15
also be a Summer meeting at such time and place as may be decided
upon by the Executive Committee. Other meetings may be called at
the discretion of the Executive Committee. The past Presidents, together
with the officers and Executive Committee, shall constitute the Council
of the Academy, and represent it in the transaction of any necessary
business not specially provided for in this constitution, in the interim
between general meetings.
Sec. 3. This constitution may be altered or amended at any annual
meeting by a three-fourths majority of the attending members of at
least one year’s standing. No question of amendment shall be decided
on the day of its presentation.
BY-LAWS.
1. On motion, any special department of science shall be assigned
to a curator, whose duty it shall be, with the assistance of the other
members interested in the same department, to endeavor to advance
knowledge in that particular department. Hach curator shall report
at such time and place as the Academy shall direct. These reports
shall include a brief summary of the progress of the department during
the year preceding the presentation of the report.

The Delta of t 16 9
Mississippi River
20 ™1.
49
between Lake Pontchartrain and Lake Borgne. This stream is evidently
a former distributary of the main stream. The bays along the edge of
the delta of which Barataria, Timbalier end Terre Bonne are examples,
show how the advancing delta arms extend around areas of gulf and
hem them in. Notice particularly Bay Marchand, at the mouth of Bayou
la Fourche, and the separation of Timbalier and Terre Bonne bays by the
long narrow delta of Bayou Terre Bonne.
This inclosing process is aided by the formation of barrier beaches
from point to point by wave action. True delta area is further indicated
by the straighter course of the river below Baton Rouge. The river is
very meandering through the whole length of the alluvial valley on
account of the gentle slope of the river bed, but below Baton Rouge it
becomes increasingly straight, although in the distance of two hundred
forty miles the fall is but five feet, or one-fourth inch per mile. _As
streams always acquire the meandering habit on gentle slopes, this ap-
parent contradiction of the law of stream flow furnishes an interesting
problem. I piopose this explanation: The river flowing into the gulf
produces a current some distance out from the shore along the sides of
which the sediment is deposited more rapidly than in the swifter central
line of flow. Finally the narrow mud banks appear above the surface
along the course laid out by the current in the still waters of the gulf.
The tendency to meander shown at the head of the delta indicates the
inclination of the stream to conform to law. The stream is forming
meanders. Below New Orleans an abrupt bend appears as an apparent
refutation of the explanation of the straight lower course. This bend
represen:s an accident in the direct forward movement of the delta. Ob-
serve the streams beginning near the eastern curve of this bend and the
tract of land extending east and partially inclosing Lake Borgne and
Mississippi Sound on the south. These streams and this strip of land
indicate a former course of the river. A crevass across the narrow south
bank caused the abandonment of the part below and the abrupt turn of
the river. saan Tee Ie RON rane ah pS INES IMIS opto cecteee: W DH Weelieonte

Commen migrant., April 1 to May 11. Loons may be seen on the
larger ponds any morning after a stormy night in April. Before the
waterworks and railroad reservoirs were made these birds were not seen.
Bollman and Evermann do not give the Loon in their lists of 1886 and
1887.

14. [144] Aix sponsa (Linn.). Wood Duck.*
Rare migrant. March 24 to May. Formerly a common summer resi-
dent (C. H. B. ’86), and the most common duck, often seen near the
campus (B. W. E. °87). Reported breeding in 1887 (G. G. W.), and in recent
years (A. W. Butler, *97).. At present this duck is extremely rare; the
only one reported since 1897 was seen in May, 1902 (T. J. Headlee).

18. [149] Aythya affinis (Eyt.). Lesser Scaup Duck.*
Common migrant. March 9 to May 8. The Little Blue-bill is the
most common duck. As is the case with the Shoveller, the first migrants
are males. The females, however, are present in larger numbers than
the males in the flocks seen later in the season.

Common migrant. February 17 to April 12. October 31 to Novem-
ber: 24. On two occasions, 3—2, ’°02 and 2—17, ’03, Wild Geese were
seen flying south. On both of these dates there was a sudden drop
in the temperature, in the latter case to six degrees below zero. ‘Those
seen 4—12, 1903, were flying through a driving rain. A Canada Goose
remained about the campus of the University for about a week ending
3—27, °02. At nights it flew in all directions over the campus from
pond to pond, and its loud calling provoked a still more yociferous dem-
onstration from the watchdogs below.

Rare migrant. One was taken alive and kept in the laboratory for
a week in May, 1902. lt was fed small fishes, which it swallowed
readily. Its appetite was amazing but was the cause of its death. A
large mass of fish bones became stuck in its cesophagus and put an
end to his gastronomic feats and to his career.

Rare migrant, not observed since 1887. “The earliest record for
Indiana is that given by Prof. Evermann from Bloomington, April 10,
1887” (A. W. Butler). Evermann also says a few were seen in August,
1886. C. H. Bollman called it a rare transient in 1886, but makes the
remark that it might be added to the list of summer residents as he
had taken it July 29, 1885. It has also been taken in this county by
I. N. Corr and S. E. Meek.
29. [201] Butorides virescens Linn. Green Heron.* Figs. 1-5.
Common summer resident. April 10 to September 22. In 1901 C. E.
Edmonson found a colony of ten or twelve nests in a small clump of
cedars near the water-works reservoir. June 3, 1901, a nest was found
in a small cedar, about 50 yards from a pond. It was 25 feet high
in a dense thicket of small trees. The nest was poorly made of sticks and
the eggs were visible from below. There were 5 eggs. On June 11
these were hatched, and on the 19th the young were well covered with
down and were hopping around among the branches (W. L. H.). May
11, 1903, a Green Heron’s nest with 6 eggs was found 13 feet up in
an apple tree in an orchard. Five eggs were in the lower layer, the
sixth on top. There was another nest about 20 feet up in an adjoining
ax
de
tree, which contained four eggs. The eggs in the first nest were hatched
May 29 (C. G. L.).

42.” [256] Helodromas solitarius (Wils. ). Solitary Sandpiper.
Common migrant and perhaps raré summer resident. April 23 to
June 9. October 6. This bird has been reported as early as March
20, but.these dates should probably be referred to some other species,
perhaps Wilson’s Snipe. One observer records it as a summer resident
while another gives a queried affirmation. The date, June 9, is an ex-
tremely late one if the Solitary Sandpiper is to be considered purely
as a migrant. But it probably indicates summer residence, since in the
Alaskan breeding grounds young have been found in the same month
'
78
(June 28, ’03, Charlie Creek, Yukon River. W. H. Osgood). A commor
bird during the migratory season in all muddy places. Seen as early as
September 20 in fall.. Will probably be found in August.

Bob-white is scarcely a common resident at present. In 1886 C. H.
Bolilmann considered it abundant. May 18, 1903, a nest and two eggs
were found in a rather damp spot in a large dense woods and June
14, young ones were seen running about with their mother (C. G. L.).
Coveys have been observed rather late; eight were seen April 15. 1902,

75. [393] Dryobates villosus (Linn.). Hairy Woodpecker.*
Common resident: breeds. A less familiar bird than the next, but
it is occasionally seen in the city. But his contact with civilization
generally gives him a dingy color and a ruffled coat.
76. [894] Dryobates pubescens (Linn.). Southern Downy Woodpecker.*
Fig. 12.
Common resident; breeds. Possibly more common than the last;
apparently so because of its more confiding attitude towards man. Nest
and one egg in a rail April 23, 1903 (C. G. L.). But the nest has been
found with only two eggs in it as late as May 15, 1901.
77. [402] Sphyrapicus varius (Linn.). Yellow-bellied Sapsucker.*
Regularly a very common migrant: occasionally a common winter
resident. Eight were seen January 21, 1903, in a group of cedars and
pines less than an acre in area. It did not winter in 1901-1902. B. W.
Evermann gives it as a rare resident, and W. S. Blatchley says it breeds.
There are no later dates in spring, however, than May 1, 1903 (W. L. M.),
and May 5, 1885 (C. H. B.). It was observed mating April 8, 1903 (W.
88
L. M.), but it would be an unusual occurrence for it to breed this far
south. According to C. H. Bollmann’s schedule for 1885 the males
arrive and depart earlier than the females.

78. [405a] Ceophleus pileatus abieticola Bangs. Northern Pileated Wood-
pecker. Ts ;
Quite rare resident; very probably breeds. Although it is now re-
stricted to the wildest and least visited parts cf the county and is present
there in but small numbers, it must haye been tolerably common as
late as 1885. Seven specimens were taken that year—March 21, Maren
22, a male; March 29, a male and a female (C. H. B.): two specimens
were taken along Bean Blossom Creek in August (3. W. E.), and one
89
Was seen December 24, by W.-S. Blatchley. It has been seen or. taken
several times since: all the dates follow: November 3, 1887, J. Gra-
ham; February 13, 1892, two seen, one of which, a female, was taken,
A. B. Ulrey; one seen in 1898 and one about February 7, 1901, V. H.
Barnett; two seen and one, a male, taken January 20, 1903, by Mr.
Whitaker. The last specimen was winged and brought in alive. It
hammered to pieces the pine box used for a cage and escaped into
the streets.. After several adventures it was. with difficulty recaptured
and placed in a wire cage at the University. He tried to shatter this,
too, but of course was. unsuccessful. His accuracy was shown by his
repeatedly pecking a wire, not more than one-sixteenth of an inch
in diameter, which he hit squarely every time. He lived about three
days in captivity. Two of these roble birds were also seen on May 17,
1954.. In a steady majestic flight they winged their way across some
fields and a highway that lay between two dense forests, their favorite
retreats.
79. [406] Melanerpes erythrocephalus (Linn.). Red-headed Woodpecker.*
Abundant summer resident; not uncommon winter resident. All of
the Redheads sometimes migrate in the fall, and leave us no winter
residents. Such was the case in the years 1892 and 1905. The autumn
of the latter year was noticeable for the very scanty production of
beechnuts and acorns. In 1893 after their winter’s absence they were
first seen April 19 and became abundant April 28 and 29 (E. M. K.).
For three years prior to 1903 the Redhead was a very common winter
resident, in fact, the most common and most equally distributed winter
bird. It became common each year from the middle of February to the
1st of March.
The mating call was heard as early as February 15, 1903. The
nest and five eggs were found May 29, 1903 (C. G. L.).
Redheaded Woodpeckers are very quarrelsome, and are continually
driving other birds from their favorite trees. Their attentions seem
especially directed against their little cousin, the Dowry, although Jun-
cos, Tufted Titmice and Nuthatches are not slighted. They have been
observed to come to the ground to attack a Tufted Titmouse. They
are capable of making as large an animal as the Fox Squirrel beat
a hasty retreat. Sparrow Hawks, too, are put to flight, but the Red-
headed tyrant often finds his master in the English Sparrow.
90
There is nothing in the Redhead to suggest the flycatcher, but he
really is an expert in that line. A flash of color often attracts your
eye to a nearby treetop, and you see that it is the Redhead, who
is diminishing the insect population. In one or two or three swoops,
as gracefully as Myiarchus himself, he obtains his luncheon.
80. [409] Centurus carolinus (Linn.). Red-bellied Woodpecker.*
Common summer resident: less common winter resident. An _ in-
crease in number is noticeable about the middle of March. Common
April 8, 1903.
A yery garrulous bird; a single individual often fills the woods with
a din of his varied cries; stimulation and excitement are not needed to
provoke a demonstration but he seems to do it for the pure love of making
a racket.
81. [412a] Coluptes auratus luteus Bangs. Northern Flicker.* Fig. 13.
Abundant summer resident and yery common winter resident. Be-
comes abundant in March. Mating call heard as early as February
15, 1903, and as late as November 20, 1902. A nest and two eggs were
found in an apple tree April 22, 1903 (C. G. L.).
82. [417] Antrostomus vociferus (Wils.). Whip-poor-will.*
Rather common summer resident, but on account of its peculiar
habits not commonly observed.

87. [452] Myiarchus crinitus (Linn.). Crested Flycatcher. *
Common summer resident. April 18 to September 7. Nestbuilding
May 14, 1901; six eggs May 27. In 1902 a nest and 5 eggs were found
May 21; the eggs were hatched June 2 and the young birds had flown
June 11 (Gertrude. Hitze). Another nest with six young about ready
to leave was found June 12. It was in a hollow apple tree about 6%
feet up (C. G. L..).
Later in the season, in August and September, these birds may be
seen trooping around with a brood of lusty youngsters almost as large

sultry brightness of an open grove or beside the dimly lighted paths

132. [587] Pipilo erythrophthalmus (Linn.). Towhee.* Fig. 21.
Abundant migrant and summer resident; common winter resident.
There is always a noticeable period in spring when Chewinks are very
scarce. This is probably due to the departure of our winter residents
before the arrival of migrants and summer residents. A marked example
of this period of scarcity is found in the record for the spring of 1902.
Up to the fifteenth of February, males and females were common and
present in about equal numbers. From this date until the ninth of March,
no Chewinks were seen. On the latter date, and for nearly a week there-
But on the
twenty-fourth of March both sexes were equally abundant and the season
of song was at its height.
after, although males were present, no females were seen.
Thus in this spring there was a_ period
twenty-three days in length when they were absent; a period of a week
When males only were present; and finally another period of fifteen days
during which the arrival of other birds brought the numbers up to the
usnal suminer abundance. This hiatus is more or less marked in every
year’s record. That the males migrate first to the breeding ground is
also upheld by all other available data.

“B.W.E.
The Chewink begins singing early. The first perfect song was heard
March 1, 1903. On February 20, however, and again on March 1, two of
these birds were found rehearsing in low tones. The first was scratching
among some briars and was going over his spring song very softly. The
notes were exactly the same; the only difference was in the volume and
the tone which seemed to express contentment rather than ecstacy. The
other one, heard on the first of March, was sitting in some cedar brush
with his feathers ruffled up, his bill sunk in his breast, muttering his
seore. This whole effort was accomplished in rather a drowsy manner
and he was so oblivious to his surroundings, that he was not frightened
by the presence of a human being within three feet of him. Immediately
after this, I heard another Chewink give the song perfectly from the top
of a chestnut tree. It was a beautiful chant and seemed unusually
attractive on this rainy March morning. The same habit of rehearsal
has been observed in several other birds, among which are the Song
Sparrow, White-throated Sparrow and brown Thrasher.
Nest and three eggs found April 15, ’03. Birds hatched on June 11,
1901, had flown June 19 (W. L. H.).A very late date is given by B. W.
Evermann. “August 19, 1881, I found a Chewink’s nest containing three
fresh eggs, built at least three feet from the ground in a spice bush. Such
is not common I believe.” (Orn. and O@6I., 1881.)

1903, but, on the same date a nest was found which contained three eggs.
This was afterwards ascertained to be the full set.

The Cardinal is another one of those cheery birds which may be heard
singing at all times of the year. Some winter dates of singing are: 10-19;
11-9, 02 and 1-1; 2-8, 03. On February 13, 1903, I heard a Cardinal sing-
ing from the top of a cedar tree at 6 a. m., and on passing the same place
at 7 a. m. found him still at his music.

very unusual. The only record of its making its summer home at

There are only two large ponds in the region, and as the Swallows
are seen at these places for a long time before they are in any other
part of the country it is easy to record their migration.
One of the peculiarities of their migration is the arrival at the same
time of all or several of the species. On one day we can find no
Swallows at all; on the next, perhaps, all, from the Martin to the
little Bank Swallows, will be present about our ponds. Four of the
species came on the same day in 1885, and three on the same day
in 1902 and 1903. After their arrival they are augmented in numbers
at the same time, or they leave, or arrive again in full strength. ‘Thus
on four days in April, 1903—the 10th, 13th, 19th and 30th—large mixed
flocks were observed, when all or nearly all of the species had been
129
absent the day before. Their departure was similar. On April 11,
17, 27 and May 1, the less vagrant summer resident Progne was the
only Swallow remaining of the motley companies of the day before.
In other years this mode of migration has been just as marked; in
1902, two species arrived together on the fifth of April and three on
the thirteenth: and in 1885, four species, the Bank, Tree, Barn and
Cliff Swallows arrived in one fiock on the 15th of April, and were
seen together again on the next day. Tree and Cliff Swallows became
common on the 22d, the Barn Swallow a day before, and on the 25th
the Bank and Roughwinged Swallows became common.
A more detailed discussion of the migration of the Hirundinide
in 1903, will bring out another point, i. e., the relation of weather con-
ditions to the phases of the migratory movement.
From April 10, the date when three species had arrived, to May 3,
inclusive, when the last flock of migrants was seen, there were just
fifteen cloudy or rainy days, with an average temperature of 47° at 5
a. m., and ten clear days with a temperature of 44.° Swallows, some-
times, with the exception of the Purple Martin, were absent [three spec-
imens of Hirundo seen one day and two of Petrochelidon another] during
the ten days, and were very much in evidence fifteen days. South winds
prevailed during this period and migration was high among all the small
land birds, especially on the 28th and 29th; but on these dates no flocks
of swallows were seen. If a clear or partly clear period was succeeded by
a rainy, cloudy, or misty one, swallows were surely to be found.
As long as the weather remained cloudy, these birds remained, but on
the first fair day they disappeared. ‘lhe only species that arrived on a
clear day was the Tree Swallow; but after its arrival its movements
agreed with those of its cousins. There was only one cloudy day on
which the crowds of swallows were absent and eyen that day brought
an increase in the number of Martins.
A synopsis of the period follows: April 10, cloudy, 3 species; April 11,
cloudy, an increase in number of Purple Martins; April 12, fair, no Swal-
lows (Martin ignored); April 13-16, inclusive, cloudy and rainy, all species
present; April 17-18, clear, no Swallows; 19-25, inclusive, cloudy or rainy,
all species present in considerable numbers; 26-29, fair, few Swallows
seen and their number decreased during this period; April 30, cloudy,
a large flock of four kinds; May 1-2, clear, no Swallows; May 3, rainy, a
9—A. or Screncr, '04.
150
flock of eighty Bank Swallows and twelve Purple Martins. After this
date only the usual summer numbers of the breeding species were seen;
there were no more migrants. The Purple Martin which seemed to be
less affected by weather conditions after arrival than the other species,
was orthodox in its arrival which occurred on a cloudy morning after a
elear night.
There is no other record so complete; and it can not be stated whether
this relation between weather and migration is a fixed one, but in regard
to the migratory movements of Swallows in 1903, it may be said that the
relation was so close that one could predict the numbers to be found on
any day from the condition of the weather.

154. [636] MWniotilta varia (Linn.). Black and White Warbler.*
Common migrant and rare summer resident. Considered a common
summer resident in 1886 by C. H. Bollmann. April 7 to October 4. Song
April 28, 1903.
In spring you will find this striped vision only on the trunks of the
larger forest trees. Although you are searching for him and feel sure of
his presence, the actual discovery is always a surprise. This little flake
of sharply contrasted colors makes its appearance so quickly that we
find it difficult to realize that it is not a piece of bark suddenly possessed
of life, but our own dear little Black and White Creeper that is before
us. In Autumn he is more democratic and is often found in lowly
thickets. Is it not because we are sated with discovery, that the thrill
of last spring is not felt when this leader of the band of wood warblers is
espied? Is it not because we have met the timid glance of the rare Cape
May, or the gaudy Magnolia through the interlacing branches, or that
here the Redstart spins his glowing pin-wheel, that the Black and White
Warbler is not again hailed as a distinguished visitor when we see him
in September clinging to the slender stem of the hazel, inspecting its sur-
face or gracefully reaching out for the slow-descending caterpillar?
Yes, we think the reason lies with the observer and not with the
observed; for we are surely not at our best when we slight our tiny
friend ever so little in the greeting. He remains always the most at-
tractive, the most dear of his woodsy clan.

Rare migrant. ‘Mr. Chauncey Juday reports it from Monroe County,
where a specimen was taken at Harrodsburg, April 26, 1895” (A. W.
Butler). E. M. Kindle reported it May 28, 1892. As nests and eggs of this
species have been taken in other parts of the State at an earlier date
than this, it is possible that the Prothonotary Warbler may be found
here as a rare summer resident.

a nest and six fresh eggs, and one of the Cowbird, near Bloomington,
May 12, 1886. The nest was at the base of a clump of ferns, and was
composed of the leayes of ‘Maiden Hair’ fern. The next day Prof. B. W.
Evermann took a nest from a similar location, containing five of the
owner’s eggs and two of the Cowbird” (A. W. Butler).
Common in the fall of 1903 in the undergrowth along creeks.

157. [641] Helminthophila pinus (Linn.). Blue-winged Warbler.*
Abundant migrant. Rare summer resident (C. H. B.—B. W. E.).
April 19 to September 28. Song April 19, 1903.
Orchards and open woods are the favorite haunts of the Blue-winged
Yellow Warbler.
On a bright day after a rainy morning in April, 1908, warblers of this
species were observed to move from one part of the country to another
about three miles away in from six to eight hours. In the morning
they were plentiful in the orchard and clearings south of the city, while
none were to be observed anywhere north of town. In the afternoon
these conditions were reversed, they were common and singing in the
orchards north of town, while they were entirely absent in the places
where they had been seen in the morning. Their movements even for
the shortest distances were always in the same direction, they flew from
limb to limb, from tree to tree, in the same general trend, toward the
north.

County it was rather common, April 27 to May 1, 1886 (Evermann,
Blatchley)’ [A. W. Butler]. During the last few years the Nashville
Warbler has been a more rare bird than the above quotations indicate.
One or two records in a migration has been as much as could be hoped
for concerning this species. April 24 to May 11. August 26 to October 19.

may observe in spring a hundred of the present species to one of the
Nashville Warbler, and in fall a thousand. The Tennessee Warblers, in
the latter season, literally fill all the trees, whether the neatly-trimmed
maples along the city streets or the magnificent oaks of the forest. The
underbrush is alive with them, they are in the weeds, in briars, and in
the stubble. Swamp and hilltop, cultivated field and forest, alike, are
animated by the hordes of Tennessee Warblers. They are everywhere.

166. [655] Dendroica coronata (Linn.). Myrtle Warbler.*
Common migrant and not rare winter resident. September 24 to
May 13. First in full plumage March 25, 1903. In winter this species
seems to prefer certain restricted localities; most of the individuals that
have been seen here in winter have been found in a dense pine and cedar
grove, but in the winter of 1902-1903, some were seen at two other places—
an open forest near a pond and an old orchard.
Recorded as wintering in 1882-5; 1884-5; 1885-6; 1886-7; 1891-2; 1892-3;
1899-1900; 1900-01; 1902-3.
The record of the appearance of individuals in different stages of
plumage for a year is as follows: those seen at intervals through January,
February and part of March were in the usual winter dress. On the
tenth of March (1903) the first change was noted. A single Yellowrump
144
was found in some bushes along a street in town. The side-spots were
large and brilliant as was also the rump. The back had the sharply
defined black and gray streaking, but the head and breast were as in
winter. March 21, a specimen in winter plumage was seen; March 23,
two individuals, one in full plumage with the exception of the crown-
spdt which was somewhat obscured by dark tips to the feathers, the
other in the usual autumnal and winter garb. March 25, four Myrtle
Warblers were seen, and of these, one had the winter plumage, two had
yellow crown and rump but no side-spots. and one was brilliant in a new
and complete spring suit. March 27, one with winter colors; March 30,
one in complete and one in winter plumage; April 1, two like the last.
April 3, three specimens with all the spots showing but only dimly on the
sides and crown. After April 3 all mentioned are in full plumage unless
otherwise stated. April 5, two, one in winter dress; April 8, four, one
in winter plumage; April 11, four; April 12, twelve; April 14, three, two of
which were clothed as in winter; April 15, four; April 19, six, one looking
just as he did in Janvary, and he was the last one observed in this
plumage, although of twenty-one seen on April 28, two were still in
transition stages of plumage. Thus fifty days elapsed between the first
and last observed changes in plumage, and, half as many days passed
between the appearance of summer dress and the vanishing of winter
garb.
In the fall the first yellowrumps were seen. on October 12 (1902). Of
thirty individuals, one had the sides yellow, while all of the others had
already assumed the sombre shades of winter plumage. October 26,
fourteen of these birds were observed and one was still in nearly perfect
summer condition, the crown and sides being only slightly dusted with
darker. Wee Me

and two eggs May 7, 1902 (G. Hitze). On May 12, 1902, five eggs were
taken from a nest; a new nest was begun on the next day; the lining
was partly made on the 14th and the nest was finished on the 16th.
There was one egg on the 17th and four on the 20th. A nest with four
fresh eggs was found June 4, 1901 (W. L. H.).
The earliest and latest individuals seen are generally found in the

195. [718] Thryothorus ludovicianus (Lath.). Carolina Wren.*
Common resident. Sings at all times in the year. The Carolina Wren
became common here about 1883 (B. W. E.). “It was heard nearly every
day that winter.”
An inhabitant of dense thickets and brush-piles. Not often seen away
from these places except when singing. Ordinarily a very hard bird to
flush. Several times the writer has cornered a Carolina Wren in a
brush-pile, and walked up to the edge of it without the bird leaving.
Once, even, I walked over a brush-heap with a wren in it and the bird
lett only when the heap was torn to pieces. (March 3, ’01). Another
instance of this habit is as follows: On a cold, snowy, windy day, I was
investigating the base of a hollow tree. After rummaging around on the
inside for three or four minutes, I touched a Carolina Wren which then
flew hastily out (February 2, ’02).
196. [719] TVhryomanes bewickii (Aud.). Bewick’s Wren.*
Very common summer resident. March 6 to October 12. Bewick’s
Wren was taken in this county as early as 1876 (Ind. Univ. Mus.). It
was a common summer resident ten years later, and now is very common
and almost entirely replaces the next species (7. a@don) which is a rather
rare bird.
Song March 13, 1903; breeding March 25, 1901. Nest and eight eggs
in an old sack hung over a fence, April 14, 1903 (C. G. L.).
Most frequently found near houses; common in the city; a persistent
songster in March and April.

Song January 18 to November 28, 1902. Mating March 15, 1902; nest-
building April 14, 1901. May 29, 1901, four young with pin-feathers and
one egg were found in a nest about three feet from the ground in a wil-
low stub. The nest was about three inches in depth and was lined with
rabbit fur and other soft materials. The young were not yet able to sit

Song heard April 16, 1902. This bird has a surprisingly loud, sharp
whistle, with a somewhat ventriloquial effect.
On April 6, 1902, a Golden-crowned Kinglet was observed to catch a
moth of apparently half its own size. It took several minutes time and
much trouble to finish the insect and it was dropped once but was recoy-
ered and finally disposed of.

207. [749] Regulus calendwa (Linn.). Ruby-crowned Kinglet.*
Abundant migrant and rare winter resident. March 23 to May 18.
September 21 to October 24. ‘They have been noted, in winter, in Mon-
roe County, by Profs. Evermann and Blatchley.” (A. W. Butler.)
Song April 5, 1901; 10, 19068. Mating April 19 and 24, 1903. April 10,
1903. Heard a Ruby-crowned Kinglet singing a varied and pretty song
which was so loud that it did not seem possible that so small a bird
eould produce it. The Ruby-crown also gave a little chuck, a short
whistle, and another note like that of a Canada Nuthatch, but less com-
plaining. The last note was repeated several times. On April 19, two
Ruby-crowns were seen, one of which with crown erected and singing,
was chasing the other. Was this not mating? On the 24th two other in-
166
dividuals were seen doing the same thing, and another was heard singing.
The song reminds one of nothing more plainly, than of the softer, less
ambitious efforts of a canary. It is varied with little chirps and chuck
and chirr notes.
The bulk left May 2, 1885 (C. H. B.).

ELECTROMAGNETIC INDUCTION IN CoNDUCTORS OF DIFFERENT
MATERIALS AND IN ELECTROLYTES.
ARTHUR L. FOLEY and CHESTER A. EVANS.
This investigation was undertaken for the purpose of determining
whether or not the character of a conductor has any effect upon the
electro-motive force generated in it when it is made to cut magnetic lines
of force.
Is the e. m. f. generated in a copper wire of given length exactly equal
to the e. m. f. generated in a silver wire of the same length when both
cut lines of force at the same rate? And is this e. m. f. equal to that
generated in a nonconducting tube of length 1, filled with an electrolyte,
when the electrolyte is made to cut lines of force at the above rate?
BHlectrolytic conduction and metallic conduction appear to be very dif-
ferent processes, why then should one expect metals and electrolytes
to give identical results from electromagnetic induction?
It is evident that many difficulties and sources of error will be
avoided if-the two conductors to be tested can be placed together and
made to cut the same field in such a manner that the resultant e. m. f.
generated is zero, provided that electromagnetic induction is independent
of the substance of the conductor. Also, the direction of the e. m. f.
must be constant if a sensitive galvanometer is to be used to detect it.
Fig. 1.
Let M (Fig. 1) be a cylindrical magnet mounted to revolve about its
axis, and let w and w' be wires in contact respectively with the middle of
the magnet and the center of the end, and connected, as shown, to a gal-
204
yanometer, G. Suppose the magnet to be revolved at a high speed. Few
lines of force cut w’, as it is parallel with the axis of the magnet. W-
is cut by the lines passing from pole to pole and if the pole strength is
sufficiently great and the magnet is revolved rapidly, the galvanometer
and therefore an induced e. m. f. If w and wt
will indicate a current
are led from the magnet as in Fig 2, it is evident that the resultant e.
m. f. generated is zero, since that generated in w opposes that generated
in w'. But suppose that w is of one metal and w' of another, if the
e. m. f. generated in each is not the same, the galyanometer, if sufficiently

tube containing an electrolyte and the electromagnetic induction in the
electrolyte measured. To increase the sensitiveness of the apparatus
»
there may be a number of w’s and w’’s connected as shown in Fig. 3.

Although considerable work has been done, it has been entirely of a
preliminary character. With a magnet of pole-strength 415, making 4,000:
revolutions per minute, with 100 copper wires (w) and 100 German silver
wires (w’), the junior author of this paper found that no current was
indicated by a galvanometer whose constant was 1.1x10-°. The magnet
was rotated by an electric motor and the galvanometer was placed on a
pier in an adjoining room some thirty feet distant. Work with electro-
lytes is now in progress.
The senior author is arranging to make the apparatus more sensitive
by using an electromagnetic field and a more delicate galvyanometer.
Results will be given in a future paper.

INTERFERENCE FRINGES ABOUT THE PATH OF AN ELECTRIC
DISCHARGE.
ARTHUR L. FoLey and J. H. HASEMAN.
Some ten years ago the senior author of this paper, while photo-
graphing interference fringes under various conditions, noticed that
fringes were produced about the path of an electric discharge. Owing to
the press of other work further investigation of the subject was post-
poned. ) -4 (OTSA) 7 (fF 1139) 4

We have in this case one, and only one, value for 22. If the surface S,
is such that in addition to (III) being satisfied, (1) are also satisfied, then
243
there is one, and only one, surface S, which represents the result of deform-
ing S, so that a conjugate system remains a conjugate system after the
deformation.
There are two cases which may occur under (III). Suppose that
P< (1D) 7 aaa 7
Ey oy 2s ee
Then 7—-+1 and the surface Se is such that its second fundamental
magnitudes D2 and D2” are either equal to the corresponding magnitudes
Di and Di’ of Si or they are the negatives of Di and Dy’.
But from the equations (*)

Where e, f, g are the fundamental magnitudes of the Gauss’ sphere, it
is seen that a change in the sign of D and D” corresponds to a change of
sign in the co-ordinates x, y, z of the surface, and therefore the surface S2
is either identical with Si or it issymmetrical to Si: with respect to a plane
or to the origin of co-ordinates.
Suppose next that

In this case there is a anique value of 22 -1. Si may therefore be de-
formed so that after the deformation is carried out the lines “=—const.,
v=const., form a conjugate system, although they do not form a conju-
gate system at any time during the deformation. Now, by a theorem of
Dini, (**) from relation (III) no surface So exists, the spherical images of
whose asymptotic lines are the same as the spherical images of a conjugate
system of lines on Si. But from the definition of associate surfaces, there
is then no surface to which Si is associated, and thus we have the result
that when (III];) is true for any surface Si referred to a conjugate system,
there exists no surface Sc to which Si is associated.

A FamIty oF WARPED SURFACES.
C. A. WALDO.
Derivation of the general equation of all warped surfaces having two
distinct rectilinear directrices and its application to a few special cases.

Let the surface be defined by the three directrices

The curve f (x’y’) = O lies in the plane z = O, the X and Y axes are
parallel to the rectilinear directrices; the Z axis includes the common per-
p2ndicular to the rectilinear directrices, unless otherwise specified.
In the diagram Fig. 1, let X’ X” be one straight line directrix at the
distance q above the plane z = o, Y’ Y”’ the other at p above z=o0. Their
horizontal projections will be the X and Y axes of reference.
246
Let (x, y, z) be any point P on the warped surface, and EK’ E’ B’”
the rectilinear element containing it.

Then by similarities and projections the following equations exist:
x’ a2 HW’ By noe | ALG) E’2 = p zs eS p x
x aa 1 D464 1B os 1D ALL Po al p—z ’ = p—z
Similarly, yy = AY
q—z
Substituting these values of x’ y’ in f (x’ y’) — o, there results the cor-
responding functional equation,
f [FE eee } 9,
p—z’ q—z
which is the equation in Cartesian co-ordinates X, Y axes general, Z
axis perpendicular to X and Y of the warped surfaces as defined above
and includes every warped surface with two distinct rectilinear directrices.
For its application it requires that a section of the surface should be
known parallel to the right-line directrices and not including either of
them. This general surface is referred directly to the orthogonal pro-
jections of two warped lines in space upon a plane parallel to both,
and to their common perpendicular. The angle at which the lines
intersect is implicitly contained in the equation of the surface. The
form of the equation of the surface does not change, therefore, when
the surface itself is deformed by changing the angle in space of the
right line directrices, provided the form of the equation of the plane
curve directrix remains unchanged.
It is also at once evident that the miethod derives immediately the
Cartesian equation of the warped surface determined by the fact that
an element cuts a curved directrix, a linear directrix and is parallel to a
given plane. This is equivalent to saying that one of our parameters
p. q. remains finite while the other becomes indefinitely great.
For simplicity suppose the three axes always at right angles to each
other unless otherwise specified.

ORDER OF THE RESULTING WARPED SURFACES.
Let fn (x y) represent a homogenous algebraic expression involving x
and y and of the nth degree.
In the fundamental demonstration,
Poet f(a ya) ht (er ya) ——1C) —. Os
If x and y are both present, the corresponding warped surface is of
the 2d order.
If x or y is absent, the resulting surface is a plane.
2: Let £ (&” y”) =e (x y) — fi (« y) — c= 0.
x? and y” both present, 4th order.
x? or y? absent, other terms present, 3d order.
x? and y? both absent, xy present, x and y present or one or both
absent, 2d order.
So nett (xy) tel (ey) foie y)) = fi Gey) —« =.
x? and y? both present, 6th order.
x? or y® absent, other terms present, 5th order.
x? and terms involving x? absent; or, y® and terms involving y? ab-
sent, 4th order,
x? and y® both absent, other terms present, 4th order.
x®, y*, and xy” and terms involving y? absent, other terms present;
or, x, y, and x%y and terms involving x? absent, other terms
present, 3d order.
To deduce the general law of order of the resulting scrolls, construct
Fig. 2. Within the squares are present all the powers and combinations
that can occur in a complete equation in x, y, of the 5th degree. The
numbers at the intersections of the lines show the order of the resulting
scroll provided at least two terms remain in our original f(x’, y’) =o, one
250
of which lies in a square two sides of which converge in the angle in ques-
tion, or one of the two terms lies in a square bounded above and to the
right by one of the lines converging at the angle, the other in a square
bounded above and to the left by the other line making the angle. Thus
below one of the points marked 5 is found the term x*y*. This term joined
with any or all others lying between the lines converging at that particu-
lar 5, will yield a scroll of the 5th order.
So also we will have a scroll of the 5th order if we select x*y? on one
side and x® on the other side of the space bounded by the lines converging
at the same point 5.
At the middle point of the whole of Fig. 2 is a vertex marked 4. The
following groups can be arranged for the equation of the curvilinear
directrix, but in every case the resulting scroll will be of the 4th order.
1. x?y2 and c present, xy present or absent,
2. xy? and c present, and other terms present besides x y,
251
3. x%y and xy? present, other terms present or absent,
4. xy and y? present, other terms present or absent (or xy’ and x”),
5. x? andy? present, other terms of lower degree present or absent.
1 and 2 are built from 4th degree terms and the resulting equation
is only the 4th.
3, has two 3d degree terms present, scroll 4th.
4, one term 3d degree, other 2d, scroll 4th.
5, built from second degree terms, scroll 4th.
Fig. 3, shows at once the order of the resulting scroll when the equa-
tion of the curvilinear directrix is marked by the presence or absence of
certain specified terms.
252
DOUBLE GENERATION.
The law of double generation is simply stated. Two straight lines are
chosen parallel to the plane of the curvilinear directrix, the three giving
rise to a scroll of a certain equation. Suppose two other straight lines can
now be found parallel to the plane of the curvilinear directrix and inter-
secting the first two rectilinear directrices. Suppose the use of the second
pair of lines gives exactly the same equation as the first two, then the sur-
face is one of double generation. For example, x’ y’=c. Substitute wuss
for x’ making p = 1 and rae for y’ making q = — 1. There results
xy =
= = c; now make p=—landq=+1. The same equa-
(1 + z)(1—z)
tion results. In fact these are the two generations of the hyperboloid of
one sheet.
It then becomes at once apparent that all scrolls are doubly generated
whose curvilinear directrix has for its equation a function of the product
term (xy), the plane of the curvilinear directrix being parallel to the recti-
linear directrices. Thus the first of the five 4th scrolls order mentioned
above, viz.: the one having xy? and c, and perhaps x y terms in the
equation of the curvilinear directrix is a scoll of double generation.
It is not at once evident that the property discussed above is €0-
extensive with all the doubly generated warped surfaces in the family
under discussion. Such surfaces may also depend upon other properties
not yet discovered.
GENERAL OBSERVATIONS.
It is evident that the validity of the demonstration does not require
the axis of Z to be the common perpendicular between the two recti-
linear directrices. If the Z axis connects the two directrices in ques-
tion and passes through the middle point of their common perpendicu-
lar, it follows at once that the demonstration proceeds as before by
parallel instead of orthogonal projection.
If we conceive the three axes of reference, under the restrictions just
given, to be oblique to each other, we find the resulting equations are still
in their simplest forms. In the surfaces of the second order the axes
would then be conjugate axes. In surfaces of higher order the axes
of reference would play the part of conjugate axes.
253
It will frequently happen that the equation of a scroll will be sought
whose three directrices are given as above, viz., two rectilinear and one
plane curvilinear directrix, but the latter in some plane not parallel to
the two former lines.
In this case additional means should be given for writing the equa-
tion of the surface under the new conditions. It will then be easy to
find a section parallel to the two right-line directrices and the problem
then is solved by the process discussed in this paper.
A modification of the method here discussed finds the equation of a
scroll given by two rectilinear directrices and a plane section of the
surface, the section being oblique to a piane parallel to the two given
straight lines

An Investigation oF N—-Rays.
R. R. RAMSEY and W. 2. HASEMAN.
This paper is an account of an attempt of the authors to repeat the
experiments of R. Blondlot in which he has discovered that there is an
invisible radiation given off from an Auer (Welsbach) burner, Nernst lamp
and other sources.
Blondlot was investigating the polarization of X-rays (Comptes Rendus,
Feb. 28, 1903) and using a feeble spark gap as a detector. He thought
he had discovered that the X-rays were polarized in certain planes. In
a few days (Comptes Rendus, March 23, 1903) he was convinced that
the effects were due to other rays than X-rays. In May of the same
year (Comptes Rendus, May 11, 1903) an article by Blondlot appeared,
entitled, “Rays from an Auer Burner.” An ordinary Welsbach burner
(Auer burner) was surrounded with an iron chimney in which a window
was cut and closed with an alumitum sheet .1 mm. thick. The radiation
from this window was allowed to fall ou the little spark gap and the
intensity of the light from the spark was seen to increase. By means
of a quartz lens Blondlot was able to detect four different wave lengths.
The intensity of the spark gap is found to have four maximums as it is
moved to and fro along the principal axis of the lens.
A week later (Comptes Rendus, May 25, 1903) Blondlot published
an article in which he gave a list of various sources of N-rays and
several means of detecting them, the chief ways being the little spark
gap; a sheet of silver heated to a very dull redness by a little gas
flame; a small phosphorescent screen which has been feebly excited by
sunlight or other source.
The intensity or brilliancy of these detectors was found to increase
when the radiation fails upon them. In this article Blondlot calls the
new rays N-rays, from the town of Nancy, his home.
In a short time afterward Blondlot published an article in which he
found that a Nernst lamp with an aluminum window is a-good source.
He also found that certain substances store up N-rays when they are
exposed to N-rays and give off the rays afterward. Among those that
store up the rays are quartz, stones and brick. Wood, aluminum, paper,
256
dry or wet, and paraffin do not store up the rays. He found that one
of the essential conditions of a substance that stores up the rays is
dryness. It is found that bricks exposed to sunlight become a source
for hours afterward.
While experimenting along this line Blondlot discovered an unex-
pected effect. While viewing a strip of white paper which was feebly
illuminated, a brick which had been exposed to sunlight was brought
near the eye and the outline of the paper became more distinct. The
intensity diminished when the brick was removed. --

PHYSIOLOGICAL APPARATUS.
FRANK MARION ANDREWS.
INTRODUCTION.
It is frequently the case that much of the apparatus required to carry
on work properly in Plant Physiology is so expensive that for any one
laboratory to possess all that is needed is quite out of the question. This
has led me to plan and have constructed a few very desirable pieces,
concerning which this paper makes mention. I am aware of the fact
that no lack of contrivances have been made to illustrate some of the
principles here set forth. However, for simplicity of construction and
perfect adaptation to the purposes for which they were intended, they will
certainly be found superior in many ways and useful by any one inter-
ested or engaged in physiological work where such apparatus would be
involved. It has therefore occurred to me to describe the various pieces
of apparatus as concisely as possible and present them, together with the
illustrations, in the following brief account:
I. HEATING STAGE FOR THE MICROSCOPE.
This piece of apparatus consists of a rectangular sheet of copper, 60
em. long, 8 cm. wide and 2 mm. thick. Figure 1 shows a view of the
lower side. It will be seen from this view that the copper does not rest
directly on the stage of the microscope but is held away from it a dis-
tance of 1 cm. This is accomplished by a strong frame of wood B,
Tn
Fig. 1.
7 cm. square and 8 mm. in height. Between the wood and the copper,
as an extra preventive against the conduction of heat in long continued
experiments, a layer of asbestos 2 mm. thick is interposed at C. The
20—A. oF SCIENCE, ’04.
306
frame of wcod and asbestos is fastened firmly to ithe copper A by copper
screws, which, however. must not reach through the wood B. In the
center of the wood and asbestos squares is a circular opening D, 12 mm. in
diameter, to allow the light reflected through the stage of the microscope
to pass through the slide. Through the side of the wood frame away from
the pillar of the microscope, as the heating stage lies in the proper posi-
tion on the stage of the microscope for observation, are two holes for
centigrade thermometers, E and E*. The temperature at E may be a
little less than at E*, and if this is the case, then an average of the tem-
peratures shown by the thermometers at E and E' should be reckoned.
It should be ascertained before the experiment that the two thermom-
eters read the same at the same temperature. As they project directly
in front during correct observation, the temperature ef both is easily seen
while experimenting. Since it is not always possible or conyenient to
carry on experiments with the ccpper plate cf the heating stage directed
to the right as would necessariiy be the case with the thermometers on
the side shown in Figure 1, another arrangement was resorted to. On the
side of the wood frame opposite E and E!' are two similar holes for
thermometers, F and F’, which allows observation while the copper plate
of the heating stage is turned to the left or the reverse position to the
one in which E and E’ could be used. It will be seen from the lower
view of the heating stage shown in Figure 1 that the bulbs of the ther-
mometers rest against the copper plate inside the asbestos square C, and
in this way the heat is readily conveyed to them. One thermometer only
might be used, but the use of two is more accurate and therefore advisa-

Notes AND PHOTOGRAPHS OF THE DEVELOPMENT OF A BUZZARD.
By D. W. DENNIS AND W. C. PETRY.
Throughout southwestern Ohio and southeastern Indiana the turkey
buzzard, Cathartes aura, is a common bird, but the nests are seldom
found. Accordingly we were glad to learn in April, 1905, that during
each of the preceding four summers a pair of these birds had nested
only a few miles away. We expected that the nest would be again used,
and on the 22d of April visited the place; we found that two eggs had
been laid and that incubation was in progress. The bird on the nest
hissed when approached, and would not leave the nest until forcibly dis-
turbed; she then ran out and flew away, but soared about overhead until
we went away, when she almost immediately returned to the nest.
This nesting site is about four miles east of New Paris, Ohio; it is
near a small creek and in a very hilly country. It is at least a half mile
from any house or highway, on the edge of a rather open woodland. The
nest itself was in a hollow sycamore log (Fig. 1) nearly five feet in diam-
eter at the butt; the cavity extends back about eight feet, where it has
a diameter of about two feet, and there it terminates abruptly. This
cavity contained a quantity of dirt and rotten wood, but nothing from
which to make a nest had been carried in. A hollow had been scratched
in the debris at the extreme end of the cavity and the eggs laid in it.
They were rather conical in shape, a little larger than a hen’s eggs, and
were white, splotched with brown.
On May 17th both eggs hatched. The young birds were very helpiess;
they could not stand in an upright position for about three weeks. That
part of the head and neck usually bare in buzzards and a line down the
center of the throat and breast were bare. The bill was very large and
its tip was sharply hooked. After the young were hatched the old birds
were never seen about the nest, though they were frequently seen “ooz-
ing” around overhead.
We were unable to learn when the young were fed. On May 27th we
went with a party of students to examine and photograph the birds and
62
nest. After photographing the nesting place (Fig. 1) the camera was
placed in the end of the log and a flash light of the young birds in the
nest was secured (Fig. 2). The birds were then removed from the nest,
photographed at closer range a number of times (Fig. 8), and replaced
in the nest. They offered no resistance whatever and seemed little if at
all frightened.
On June 3d and June 9th other photographs (Figs. 4 and 5) were
taken. The birds had by this time become larger and much more active
than before; on the latter date when they were placed in the end of the
log they at once hurried to the darkest corner. Also on this latter date
they first attempted to defend themselves by vomiting up a portion of
their food. It may be easily guessed that this is a very efficient means of
defense.
On June 18th, when we next visited the nest, we found but one bird
in it. The tenant of the farm afterward told us that several days before
he had noticed that one of the birds was dead and had removed it from
the nest. The remaining one was in no way injured and we were unable
to learn what had killed the other. We removed and photographed the
living one (Fig. 6). At this time, 32 days after hatching, the black pri-
maries and tail feathers were beginning to appear but were not conspicu-
ous enough to show in the photograph.
By July ist the black primaries had become very noticeable, as
shown by Fig. 7. When the bird had been pulled to the end of the log
with a stick, it was usually seized by the tips of the wings and carried
out to the front of the camera, which had previously been set up in a
suitable place. When it had been set down it would always stretch its
wings to their full extent before folding them. Figure 8, taken when the
wings were thus extended, shows well the black feathers in the hack.
wings and tail.
Figs. 9 and 10, taken July 9th, and July 15th, respectively, show the
gradual change from white to black. By the latter date the back had
become almost entirely black, but the breast and belly were still pure
white. The bill had become more slender and more sharply hooked. The
bird would now strike vigorously with its bill at anything that dis-
turbed it.
Fig. 11 was taken July 23d. This was 67 days after hatching; the
wings and back were entirely black and there were many black feathers
65
on the breast and belly. The head was bare with the exception of short
down on the back part. The bill was still of a dark color, though chang-
ing toward reddish.
On July 30th, when we returned, the bird was in the stump at the
butt end of the log; it was easily caught and placed in a position favor-
able for photographing, when suddenly it sprang off the log and flew
away; its flight was difficult and at no time more than 20 feet above the
~ ground; after flying about 100 yards it alighted on a fence; we at once
followed it with tbe camera, hoping to get close enough to get a good pic-
ture, but whenever we approached within about 50 feet it would again
fly. We finally secured a picture (Fig. 12) at about 40 feet distance. At
this time, 74 days after hatching, the bird was almost entirely black, and
fully as large as an adult bird; a little of the white down still remained
on the sides, about the neck and legs and on the under sides of the wings;
from a distance one would have been unable to distinguish it from an
adult.

OBSERVATIONS OF THE TOTAL SoutaR Eciipse oF Auvaust 30TH,
1905.
By Joun A. MILLER, INDIANA UNIVERSITY.
Early in the year 1905 the Observatory of Madrid published detailed
information regarding the eclipse that was to occur on August 350th of
that year. Among other things this “Memoria” contained the results of
a long series of observations of the prevailing meteorological conditions
of many stations well distributed along the path of totality in Spain.
The state of the sky in the immediate vicinity of the sun had been ob-
served daily from 12:30 to 1:30 p. m. (the time at which the eclipse oc-
curred) from the 15th of August till the 15th of September. The results
of these observations, as well as the data gathered by the regularly estab-
lished meteorological stations, touching the mean relative humidity, mean
temperature, the velocity and direction of the prevailing winds, etc., had
been tabulated. From these data it appeared that the probability of clear
weather in the eastern half of the belt was exceptionally large, and
indications for good eclipse weather were perhaps best in the regions near
Ateca, Almazin and Daroca. The eastern half of the belt of totality in
Spain held about 50 eclipse stations, established by astronomers from
every nation of Europe, from the United States, and Mexico. The Lick
Observatory expedition was located near Ateca; the United States Naval
Observatory at Daroca. The observers from IWirkwood Observatory,
Indiana University, Bloomington, Indiana, chose Almazin, Spain a
small town northeast of Madrid in the Province of Soria. The approx-
imate position of this station is longitude—13 m. 56 sec. W. of Greenwich,
latitude—41° 10’.
The party consisted of Professor W. A. Cogshall, of Indiana Univer-
sity; Messrs E. C. Slipher, I. A. Cruli, and C. J. Bulleit, students of the
university: Professor A. F. Kuersteiner, Mrs. Miller, and myself. We
were assisted in the manipulation of our instruments on the day of the
eclipse by Mr. and Mrs. Charles W. Thompson of California, and Senores
Louis Nebot, Francisco Jodra, Victor Jiemenez, and Esteban Milla, of
Almazan.

The obscrvations planned were: (1) Photographs of the corona; (2) a
photographie scarch for intra-mercurial planets; (8) a photograph of the
spectrum of each of the flashes, and a photograph of the spectrum otf the
corona during totality.
For photographing the corona we used four different cameras. The
first was a ‘‘tintype” lens kindly loaned us by Mi. Spratt of Bloomington.
It has an aperture of two and one-half inches and a focal Jength of eight
inches. Three plates were exposed in this camera and on them we hoped

to get long, faint coronal streamers. The second was a portrait lens of
the Petzval pattern, of five inches aperture and focal length twenty-eight
inches. This is an exceedingly good lens and gives superb definition over
a small area and is very rapid. In this camera we exposed five plates,
varying the exposure from two to 84 seconds, hoping to get detail of the
outer corona and in the longer exposures to detect the presence of faint.
streamers. The lens of the third camera is the visual objective of the old
telescope used by the late Professor Kirkwood and others for many col-
lege generations. Its diameter is three and one-half inches and its focal
73
length fifty inches. In this camera we exposed four plates. These three
cameras, together with a spectrescope, were mounted on a wooden polar
axis that was built at the camp.
The objective of the fourth camera has a diameter of nine inches and
a focal length of 60 feet. This lens Was constructed by Mr. O. L. Petit-
didier. The front lens is of the ordinary crown glass, and the back lens
of a boro-silicate flint. Quoting Petitdidier from a letter to the writer:
“rom the point of view of constants they (the pieces of glass) leave
nothing to be desired, as the proportional dispersion is practically the
same in all parts of the spectrum, so that we should have a perfect
achromatic.’ When the samples of the boro-silicate came, however, it
was found that it had a decidedly yellow tinge. It was found also that
its composition was unstable, and that it oxidized very rapidly in the
presence of moisture. After a conference with Mr. Petitdidier, however,
we decided to have our lens made of the boro-silicate flint, and to seal it
in an air-tight box as soon as it was finished, and to open the box only
a few days before the eclipse. Petitdidier had much difficulty in polishing
the lens, owing to the fact that it oxidized so rapidly. He found after
much experimenting, a solution that would remove the oxidation without
affecting the surface. Jt was with some misgiving that we shipped the
lens, but we found on opening it that it had not tarnished in two months,
and the surface on the day of the eclipse was as perfect as the day the
lens was finished. The air was very humid on the days following the
eclipse, and the boro-silicate flint had begun to tarnish slightly when the
lens was packed for shipment home.
This camera was mounted horizontally and fed with a coelostat. A
light-tight tube, the outer and inner walls of which were of white canvas
and building paper respectively, and which were separated four inches,
led from the objective to a dark room in which the plates were exposed.
Neither the plates nor the lens was in contact with the tube. The entire
instrument was covered with an A tent of white canvas. The plate-
holders containing the plates were fastened to a large hexagon, which
the operator could revolve at will upon an axis which was parallel to the
earth’s axis. It was provided with a stop which enabled the operator to
bring the plates for the successive exposures quickly and accurately into
position. All the slides had been drawn from the plate holders before
totality began. The hexagon as well as most of the mechanical parts of
74
the coelostat, were designed and constructed by Professor Cogshall.
Six exposures were made in this camera, of duration one-half second, two
seconds, forty seconds, one minute, fifteen seconds, and one-half second.
The plates used were Seed’s 27, gilt edge, heavily backed.
If there be intra-mercurial planets, and if they, as do all other bodies
of the solar system, move in the plane of the equator of the body around

required by Bode’s Law, the major axis of their apparent paths as seen
from the earth on the day of the eclipse should have subtended an angle
of 23° and the minor axis about 3°. We decided to photograph this region
in duplicate. For this purpose we used six cameras of 136 inches focal
length, four of which had an aperture of 84 inches and were made by
Petitdidier, and two of which had an aperture of 3 inches. These were
built by the Alvan Clark and Sons Corporation. These lenses were cor-
rected for the minimum focus “# 4750, which is well within the region
for which the Seed 27 plates, which we used, are most sensitive. AJ

the cameras were mounted on the same polar axis. They wete mounted
in pairs, each pair covering in duplicate six and one-half degrees, so
that the three pairs covered in duplicate a region along the sun’s equator
twenty degrees long and six degrees wide. By a series of experiments
we had found that a plate exposed in one of these cameras for three
minutes and forty-five seconds, at a time when the sky was as dark as

it was estimated it would be at the time of totality though fogged some-
what by the skylight would show more and fainter stars than if exposed
for a shorter time. We had made exposures varying from one to four
minutes in the vicinity of Regulus when it was near the meridian begin-
ning when Polaris was just visible to the unaided eye. We decided to
expose the plates for the intra-mercurial planet for thrve minutes and
twenty seconds.

The weather on the day of the eclipse was disappointing. For two
hours before totality the entire sky was covered by light, though un-
broken, clouds. At the time of totality, however, the clouds in the im-
mediate vicinity of the sun appeared to break away, and the inner corona
shone through light, drifting clouds. No clear sky was visible, however,
within several degrees of the sun, neither Mercury nor Regulus could be
seen from this station. During the morning a moderate wind prevailed,
the general direction being W. N. W. The first contact was, neglecting
seconds, at 11:41. The weather conditions during the eclipse, as observed

Considering the weather conditions, our plates are very satisfactory.
The shortest exposure, showing the prominences, suffered very little.
The very bright group on the eastern edge of the sun is particularly well
defined, and the negatives made of it with the long-focus camera hold a
wealth of detail. The longer short exposures with the long-focus as well
as the short-focus cameras show considerable coronz detail, while the
longest exposures have that part of the corona uncovered by the clouds
much overexposed, while the clouds made it impossible to register any
extended streamers. All the plates lack the definiteness that would have
77
resulted from good seeing. The longest extension of the corona that we
obtained was about three-fourths the sun’s diameter.
The exposures of one-half second with the 60-foot lens showed the
prominences overexposed, while the exposure of two seconds was too
short to register more than a suggestion of the inner corona. The ex-
posures given in the 50-inch camera, viz., 24 seconds, 29 seconds, 184 sec-
onds, and 25 seconds, were about right, and the results obtained with this

lens are more satisfactory than any others with the short-focus lenses.
The exposures given in the portrait lens, viz., 2, 24, 29, 84, and 16 sec-
onds, were too long. All plates exposed except the fourth in the portrait
lens, which was a lantern slide, were Seed 27, and all were heavily
backed to prevent halation. Of the small cameras the negatives of por-
trait lens, suffered most, because the part of the corona that we hoped
they might contain was covered by the clouds. The negatives made with
the fifty-inch camera are particularly good and hold a wealth of complex
detail. An examination of these negatives shows that the coronal strue:
78 os
ture is more complex than in 1900. In particular that the polar streamers
instead of being radial, are bent and interlaced, and in every case long
coronal streamers are above the prominences.
The plates exposed for the intra-mercurial planets are heavily fogged,
as one would expect from a sky covered with bright clouds, but not so
badly as to obscure faint star-images. I believe that a plate of the sen-
sitiveness of the Seed’s 27, which we used, can be exposed three minutes

without serious fog at a time of a total solar eclipse. Our sky was so
cloudy that it is unreasonable to expect star-images on these plates.
We examined two of them hurriedly (the ones on which Regulus should
have appeared), but found no star-images. The photograph of the corona
on one of the intra-mercurial plates showed longer extension than on any
other plate we exposed—due perhaps to the shifting of the clouds during
the long exposure.
The corona impressed me as being brighter than in 1900. The effect
on the clouds of the light from the eclipsed sun was peculiarly striking,
and from a spectator’s point of view was very beautiful.
79
The indescribable deep blue of the great clouds, bordered with what
any one but an eclipse observer would call a silver lining, was totally
unlike anything I have ever seen, and was strikingly beautiful.
The expedition is under many obligations. The Indiana University,
The Indianapolis News and the Reader Magazine bore the expenses of the
expedition. While the authorities of the university and the managers of
the News gave kindly counsel and aid, Professor Cogshall, conjointly with
the writer, worked incessantly for the success of the undertaking from the
beginning to the end. Messrs. Slipher, Crull and Bulleit. were with us
three weeks before the eclipse occurred and rendered daily and indispens-
able assistance; while the entire staff of observers contributed materially
to the success of our plans. The Spanish government admitted our in-
struments free of duty, the alcalde (mayor) of Almazéin rendered timely
and efficient aid in the selection of the site for our camp, and in the pro-
tection of our instruments. Benj. H. Ridgely, American Consul-General
at Barcelona, manifested in every way a kindly and. intelligent interest
in the work of the expedition.

Treevevint Factors In BrraANGENTIALS OF PLANE ALGEBRAIC
CURVES.
By U. S. Hanna.
Three years agoI presented a paper to the mathematical section of the
Academy dealing with the proof of a formula used by Mr. Heal in an ar-
ticle published in the Annals of Mathematics, vol. VI, page 64. This
formula was used by Heal in freeing a bitangential of the plane quintic,
which he had developed in a previous paper in the Annals, vol. V, page 33,
from an irrelevant factor, the square of the hessian of the quintic. Since
then I have continued the study of the subject and wish to present an in-
teresting result in the light of Heal’s work.

Any point on the line through the points x and y may be represented
by 4x + y, where 4 and have a fixed ratio for any particular point. If
x be a point on the n-ic and y be a point on the tangent to the n-ic at the
point x, then we have equations (1) and (2) satisfied by the points x and
y respectively, and equation (2), as an equation in y, represents the tan-
gent to the n-ic at x. If, in addition to these conditions, the point
2x + my lie on the n-ic, we must have from (1)

Equation (3) is an (n-2)-ic in 2 and » which gives the positions of the
remaining n-2 intersections of the tangent to the n-ic at x with the n-ic
itself. In order that this tangent be a bitangent the discriminant of equa-
tion (3) must vanish. This discriminant is a function of x and y, and if y

can be expressed in terms of x, then the discriminant becomes a bitan-
gential of the n-ic. It has been shown by Jacobi and Clebsch that this is
always possible.
We shall write equation (3) as
Ap 22-2 + (n — 2) Ay AB3 pp + (n — “ & =a) Ao An-4 2 4 «-.

where we put H — Ao Ao— A? and G= A? A;—3 Ao Ai Ao + 2 A}, and the
y can easily be expressed in terms of x for the functions G and H, but the
result contains the square of the hessian of the quintic as an irrelevant
factor. This factor can be discarded without difficulty by putting
G?+4H3= Aj | (Ao As SAS IAG) =A AA An (a &s— ap |,
and then expressing y in terms of x for each parenthesis separately.
If the n-ic be the sextic, the discriminant of (4) is
*o° (3 — 2732) = O,
where I — Ao Ay —4 A Ai, Az + 3A2 and A? J = Ao HI — G? — 4H*.
There is no difficulty in expressing y in terms of x for the function I,
and therefore, by multiplying and dividing the discriminant by A§, we
can immediately write a bitangential of the sextic by substituting the re-
sults obtained for the quartic and quintic in

But this bitangential of the sextic contains the sixth power of the
hessian of the sextic as an irrelevant factor. In order to free it from this
factor, we put
J = (Ao Az — A?) As — (Ao As — Ai Az) As + (Ai As — A?) Ag,
and then express y in terms of x for the function J. The work involved
in this last step is very long and tedious. These results can be used in
developing a bitangential of the septic, but two additional functions
will have to be developed, the work in which is almost beyond the range
of possibility.

On THE WEATHERING OF THE SUBCARBONIFEROUS LIMESTONES OF
SOUTHERN INDIANA.
By E. R. Cumines.
The subearboniferous (Mississippian) limestones of southern Indiana
comprise three formations known in the ascending order as the Harrods-
burg, Salem (Bedford) and Mitchell limestones, and having a combined
thickness of at least 350 feet. These rocks are in the main very pure car-
bonate of lime. Some shaly layers are to be found in the Harrodsburg
and Mitchell limestones which may contain very little lime; and the
Harrodsburg is rather lower in the per cent. of lime carbonate than the
other two formations. Analyses of the Salem limestone show from 97.9
per cent. to 98.4 per cent. CaCo,, with the baiance consisting of magne-
sium carbonate, and oxides of iron and aluminum, with traces of silica
and other substances. Analyses of Mitchell limestone show from 96.65
per cent. CaCo, to 99.04 per cent., with the balance consisting of mag-
nesium carbonate, iron, aluminum, and silica as in the Salem limestone.
Satisfactory analyses of the Harrodsburg limestone are not at hand. Of
these limestones the Salem is the most constant in composition and is on
the average the highest in per cent. of CaCo,.
In texture the three limestones vary widely. The Harrodsburg is
rather thin bedded, coarse-grained, fossiliferous, in some cases decidedly
crystalline in structure, and contains geodes abundantly, in the lower por-
tion especially, and bands and knots of chert. There are layers and
lenses of shale. The Salem limestone, on the contrary, is, as is well
known, almost without bedding planes. It is a massive, odlitic or gran-
ular-crystalline, close-grained rock frequently cross-laminated and quite
free from geodes and chert. Its fossils are usually minute, foraminifera
and small ostracods predominating. The Mitchell limestone is in the
main thin-bedded, hard, fine-grained, sometimes almost lithographic, with
frequent alternations of shaly layers. It is in general unfossiliferous.
Bands and knots of chert are very common, but geodes are infrequent.
All these limestones are conspicuously jointed. The Mitchell shows
the cleanest and most numerous joint planes; but the best examples of
86
deeply opened joints are to be found in the Salem. The joints run
nearly east and west and north and south. In other words, one set runs
with the dip, and the other with the strike. The dip joints are the most
conspicuous.
The weathering of these limestones does not differ in essential fea-
tures from that of limestones in general, except as it is influenced by
local conditions of temperature, rainfall and drainage, and by the ex-
ceptional purity of the rocks. It is to be expected that a nearly pure
carbonate of lime, in a region of rather copious rainfall and mild climate
would weather almost entirely by solution and other chemical processes,
rather than by mechanical processes. The limestones in question exbibit
the effects of solution on such an extensive scale as to warrant calling
particular attention to them; and it is for this reason that the present
paper has been prepared. To this end attention has been called to the
composition, texture and structure of these rocks, even at the expense
of repeating descriptions already many times recorded in the literature
of Indiana geology. It is only by understanding the intrinsic nature of
a rock that we can correctly appreciate and explain its metamorphism,
whether it be in the zone of weathering or in the deeper zones.
The chief agent of weathering in the present case is meteoric water
charged with CO, and with organic acids (humic acids). The normal
annual rainfall in the region under consideration is 42 inches (somewhat
more in the southern counties), rather evenly distributed throughout the
year. The largest average precipitation has been in the month of July,
while the minimum has been in the fall months—September, October,
November. The mean annual temperature is 52° F. The topography of
the limestone region excepting its eastern and western borders is undu-
lating, and of rather mild relief. Rolling uplands in which the larger
streams are rather deeply intrenched are the characteristic features. The
conditions are therefore such as to admit of a comparatively copicus
entrance of water into the rock and free egress at lower levels into the
main streams. Such conditions favor solution. Solution has also been
favored in the past by the heavily forested condition of the region before
its settlement by the white race.
The water which finds its way to lower levels in the rock than can
be tapped by the local drainage is frequently returned to the surface
along joint planes in the deep valleys on the western border of the region.
A notable instance of this is the French Lick Valley, which must derive
87
its mineral waters, now rendered famous by extensive exploitation, from
the uplands of the Mitchell limestone, some fifteen or twenty miles to
the eastward. These waters, which reach the deeper zones of flow, are
always strongly impregnated with mineral salts. Much of the mineral
water of the French Lick Valley comes from a depth of 400 to 500 feet.
Owing to the depth to which it descends and distance which it travels,
the water has been brought into intimate contact through a consider-
able interval of time with these eminently soluble limestones and its
highly mineralized condition is an evidence of the vast amount of ma-
terial removed from them, most of which, however, has undoubtedly been
derived from a comparatively superficial zone.
The most conspicuous effects of solution are those produced at or
near the surface of the rock, and it is these that the photographs pre-
sented herewith illustrate. In quarry openings where the rock has
been taken down along a joint plane, so as to expose the wall of one
of these avenues of ground-water, the effects of solution are shown in
greatest perfection of detail. The dip joints are often greatly enlarged,
their walls pitted and honeycombed, and traversed by arborescent sys-
tems of small openings through which the carbonated waters have eaten
their way; and the once solid rock is reduced to a crumbling earthy sub-
stance stained and rusted with iron. Where two joints (dip and strike)
intersect, the enlargement is apt to be greatest, giving origin to funnels,
narrowing gradually downward, and showing in a beautiful way the
method of formation of sinkholes, which are only such funnels of solu-
tion grown large.
Where the surface of the limestone has been denuded of soil, for
quarrying purposes, it is found to be corroded to a remarkable extent.
Every dip joint now becomes a ragged furrow, and between joints the
rock rises in hummocky ridges, the hog-backs of quarrymen. Points and
knobs and mushroom-like projections meet the eye at every turn—hbe-
wildering in variety and impossible to describe. The hog-backs frequently
stand as high as a man’s head, and their flanks are scarred and scored by
the all pervasive attack of the dissolving water.
Except where the activities of man or nature have removed it, a
blanket of red soil overlies and hides this marvelous complex of cor-
roded rock. The red soil or clay is the minute remnant of the original
rock, left after the lime carbonate has been carried away in solution by
the water. It is the insoluble residue. So complete has been the removal
88
of the lime that this residual soil requires the addition of lime to render
it fertile. A handful of soil may be treated with acid without giving an
appreciable effervescence, even though the soil be taken from within an
inch of the limestone. Analysis of this clay reveals about 67 per cent. to
80 per cent. silica, 8 per cent. to 14 per cent. aluminum, 6 per cent. or 7
per cent. iron oxide (Fe.O,), and very small percents of lime, magnesia,
soda and potash, etc. The iron is responsible for the intensely red
color of the clay. The process which has produced this soil is the solution -
of the limestone with oxidation of the iron which exists in minute quan-
tities in the original rock as a protoxide. The surface of the limestone
beneath the soil, besides being rough and ragged as explained above, is
usually minutely roughened, though sometimes fairly smooth, especially
in the Mitchell limestone. In some cases, especially in the Salem lime-
stone, the rock in contact with the overlying soil is rotted and discolored
beyond recognition and shows a graded passage from sound unmodified
rock below to soil above. Where layers of shaly rock occur, as in the
Mitchell, they are often so rotted that while they retain much of their
original appearance and stratification, they may be removed with pick
and shovel as easily as any clay. Sometimes a layer of limestone over-
lying a layer of shale is left as an isolated chain of boulders in the gen-
eral mass of residual soil. The deepest accumulation of residual soil
seen by the writer is in the cut on the Illinois Central Railroad in the
northwest edge of Bloomington, where it is 30 feet deep. Usually
it is not more than five or six feet deep. Over the Mitchell and Harrods-
burg limestones the soil contains chert, and, in the latter rock, geodes
in abundance, because of the relative insolubility of these substances.
Where blocks of Salem limestone are exposed at the surface to the
rain they become deeply furrowed by the solvent action of the rain-
water running over their flanks. The faces of old ledges, long exposed to
the weather, are scarred and seamed by this action and extensively
honeycombed, owing to the unequal solubility of the rock. In these holes
and pockets on the rock surface small plants find lodgment and by the
mechanical action of their roots and the chemical action of the pro-
ducts of their decay, greatly aid the process of disintegration.
The effects thus far described are seen to best advantage in the
exposures of the Salem limestone. The Mitchell shows to a pre-eminent
degree the deeper-seated effects of solution in the formation of caverns
and underground streams. Everywhere the surface of the country occu-
89
pied by the Mitchell limestone is dotted over with sinkholes, and the hill-
sides along the larger streams abound in springs and entrances of caves.
Some of the caves, such as Marengo and Wyandotte, have attained wide
fame. The Mitchell is, as indicated above, conspicuously jointed but fine
grained. _ the groundwater is compelled to traverse the joints rather than
the pores of the rock, and it is this, in the writer’s opinion, that has caused
the more extensive development of caves in the Mitchell than in the Salem
limestone, since the two must be about equally soluble. It is the con-
centration of solution along joinis and bedding planes that gives rise to
caves. The Mitchell has both an elaborate system of joints and numerous
relatively impervious layers to serve as cave floors. Neither of these
conditions would avail, however, withcut the third condition, adequate
drainage, which has been supplied by the intrenching of the main streams
as explained above.

ACTION OF CALCIUM CHLORIDE SOLUTION ON GLASS.
By P. N. EVANS.
In the course of some recent experiments on boiler corrosion the
author had occasion to place various dilute solutions in contact with iron
wire in glass bottles and heat them in an autoclave containing water up
to 200 pounds steam pressure, which corresponds to about 200 degrees
Centigrade. The heating was continued for periods ranging from ctbree
to seven hours.
The solutions were all about fifteenth-equivalent-normal in strength,
and included the following substances, separately: sodium nitrate, am-
monium nitrate, calcium nitrate, nitric acid, sodium chloride, calcium
chloride, magnesium chloride. In each case 250 ce. of the solution was
heated in a 500-cubic-centimeter bottle.
In most cases the bottles were appreciably attacked by the solu-
tions, so that the glass stoppers could not be removed and the bottles
were noticeably etched inside, sometimes with the formation of scaly
matter on the bottles and in the enclosed water.
The effect was very much the most pronounced in the case of the
ealcium chloride. The solution was heated for 6 hours in a bottle of clear
glass of good quality, weighing empty about 275 grams. On opening the
autoclave the bottle was found to have been eaten through near the bot-
tom and the rest largely covered with a gelatinous layer which hardened
in a few days to an opaque coating. The piece of iron wire in the solu-
tion throughout the heating had gained very slightly in weight and in
tensile strength. Also, about 90 grams of loose scaly material was found,
and the solution, which had been perfectly neutral, had become strongly
alkaline. Apparently fully half of the glass had been acted upon, so
that this very dilute calcium chloride solution, containing less than 1.5
grams of calcium chloride, had in about 6 hours chemically attacked
over 100 grams of glass.
In seeking an explanation of the results, the various constituents of
a calcium chloride solution may be considered. These include, according
to generally accepted modern theories, water, calcium chloride moiecules,
102
perhaps some hydrated calcium chloride molecules, calcium ions, chlorine
ions, calcium hydroxide molecules, hydrochloric acid molecules, hydrogen
ions, hydroxyl ions.
Of these ingredients water can hardly be the active agent, or equally
marked results would have been obtained in the other cases; of the
other chemical substances present, all but calcium chloride molecules—
anhydrous and hydrated—were present in approximately equal quantities
in other solutions tested without corresponding results. The action, then,
must be considered catalytic, on account of the quantities involved, and
induced by calcium chloride molecules, anhydrous or hydrated, and is
apparently the hydrolysis of the silicates of the glass, with the forma-
tion of more or less hydrated silica and free bases.

DETERMINATION OF EQUIVALENT WEIGHTS OF METALS.
JAMES H. RANSOM.
Some years ago I presented to the State Science Teachers’ Association
a description of an apparatus for determining the equivalent weights of
the metals. The object was to devise an apparatus so simple and inex-
pensive that it might be used in every high school. That apparatus,
which consists only of a flask and stopper, gives fairly accurate results,
and where more complicated apparatus is not available it may well be
used instead of giving up the determination of at least one of these most
important chemical constants.
In colleges, however, where a greater variety of apparatus is avail-
able, it has seemed desirable to use apparatus which necessitates more
care in its adjustment. It is desirable because the student becomes
interested in working with complicated pieces, and on that account recalls
more vividly the thought back of the method. Also I have found that
with the apparatus about to be described the students of average ability
obtain results more nearly in agreement with one another and with the
theory.
The pieces of apparatus needed are two litre flasks, a two-hole rubber
stopper, separating funnel, test-tube, pinch-cock, glass tubing and rubber
connection. The accompanying sketch shows the apparatus when ready
for use.
A weighed quantity (.6 to 1.0 grm.) of pure zine is put into a test-
tube and this put into one of the litre flasks. The flask is filled with
water which has been slightly warmed to expel the dissolved air. The
stopper, carrying the separating funnel with the tube long enough to
reach to the bottom of the test-tube, and also carrying a tube bent to
a right angle and reaching nearly to the bottom of the flask, is ad-
justed in the flask so that the tube of the funnel will enter the test-
tube and reach nearly to the zine. When pressing the stopper into
place the exit tube should be closed with the pinch-cock and the funnel
stop-cock opened so that water will fill the tube of the funnel up to the
stop-cock or above. Now by allowing water to flow from the funnel
104
into the flask the exit tube may also be filled with water. When this
has been accomplished the apparatus is tested for leaks by closing the
stop-cock and opening the pinch-cock. Should there be a leak, water
will siphon out. No water should remain in the bulb of the funnel.
When the apparatus is tight an accurately measured yolume (15 to
20 ce) of concentrated hydrochiorie acid (dilute acid can be used with
magnesium) is put into the separating funnel; the exit tube is put into
the second flask which has previously had its sides dampened with water.
About one half of the acid is now allowed to flow into the tube con-
taining the zinc. A rapid evolution of hydrogen occurs which drives
water over into the second flask. When the action slows down more
acid is run in, care being taken that at the end the surface of the acid
is just at the stop-cock. When all the metal has dissolved (it may take
one-half hour) the surfaces of the liquids in the two flasks are brought
to a level by raising or lowering one of them, and while level the pinch-
cock on the exit tube is closed. The stopper is now withdrawn from
the generating flask and the temperature of the water in it is taken.
Also the reading of the barometer is noted. The volume of ihe water
in the receiving flask is carefully measured and from its volume the
volume of the acid used is deducted. The remainder is the volume of
hydrogen produced during the action. This is corrected to standard
conditions, and from the corrected volume and the weight of zinc used
105
the weight of zinc necessary to produce 11.2 litres of hydrogen is eal-
culated. (11.2 litres of hydrogen weigh one gram).
The accuracy of the method was tested by Mr. Isimerline, a soph-
omore student in chemistry, who made three determinations each of
three metals. The average of the closely agreeing results is as follows:
aluminum, 9.02 (theory 9.08); magnesium, 12.08 (theory 12.18); zine, 32.55
(theory 382.7). In a class of 70 freshmen who had worked in the lab-
oratory only 18 hours, and using horn-pan balances, the average of 37
results picked at random was 31.9.
The apparatus apparently gives good results even in the hands of in-
experienced men.

STUDIES IN CATALYSIS.
By James H. Ransom.
In 1902 there was presented to this Academy by Mr. E. G. Mahin,
working in my laboratory, a paper dealing with the action of heat on
mixtures of manganese dioxide and potassium chlorate. In this paper
it was shown that the nature of the reaction as wel! as the temperature
of decomposition depended on the purity of the oxide, in that the purer
and drier the material the higher the temperature of rapid decomposition
and the smaller the amount of chlorine and chlorine oxides. The study of
this action has been continued by the writer, and some new data accumu-
lated.
Instead of using the purified commercial article, manganese dioxide
was prepared in the laboratory by heating chemically pure manganous
nitrate to a high temperature as leng as decomposition occurred, and
then washing out all soluble material. After this treatment the residue
was dried for some hours at a high temperature in vacuo. It was then
preserved in glass-stoppered bottles in a desiccator. Prepared in this
way the oxide is not hygroscopic.
One to two grams of potassium chlorate, free from chlorides, was
mixed with about the same weight of the manganese dioxide and the
mixture heated in an air-bath, the temperature being controlled with a
gas regulator. With the purified material there was observed little or
no decomposition at 170° (as Mahin found), and only at 245° to 260°
was the action at all perceptible. At 800° to 310° the action completed
itself in a few minutes. It was observed that while little oxygen was
evolved below 245° the residue gave a test for chlorides, though the
tests made before heating gave wholly negative results. Some of the
experiments showed less loss in weight during heating than that corre-
sponding to the chloride found by titration against standard silver nitrate.
Occasionally, however, the loss was even greater than that calculated
so that it was felt that great reliance could not be placed in the difference
in weight, especially as the tubes were often heated continuously for some
days. The evidence of decomposition rests, therefore. on the formation
of chloride.
After these facts were established twenty experiments were per-
formed to find the amount of chloride produced at different tempera-
108
tures; and to determine, if possible, the lowest temperature at which any
chloride would be formed. The temperatures varied in the different
experiments between 90° and 200°, and the time of heating from one
hour to 21 days. Chlorides were found in each of the 20 experiments,
and the amount varied somewhat regularly with the increase of temper-
ature and the time of heating. At 90°-93°, the lowest temperature used,
the amount of chloride formed in 14 days was .22 per cent. of that theo-
retically possible.
In order to show whether the pure chlorate would decompose at all
under these conditions some of it was heated in the same manner as
that described above. The heating was continued for nine days at 106°-
109°. But not a trace of a chloride was produced.
It is interesting to note that decomposition begins 200° below that
at which it is sufficiently rapid to be easily observed. But this is in
line with the modern idea that the velocity of an action is a function
of the temperature. And this observation has its parallel in the fact
that 200° below its ignition point hydrogen combines with oxygen in
quantities sufficient to be determined.
It has been found also that mixtures of manganese dioxide and
potassium perchlorate produce oxygen at a temperature much lower than
that necessary to decompose the perchlorate alone. The amount of
oxygen is quite appreciable at 310°, but does not become rapid at 360°—
a temperature below that at which the perchlorate begins to evolve
oxygen.
In order to compare the action of other catalytic agents at low tem-
peratures mixtures of potassium chlorate and platinum black were
heated at two temperatures: one sample for 6 days at 145°-150°, the
other for 7 days at 95°-100°. Both tubes lost in weight and both gave
evidence of considerable amounts of chloride produced. I hope soon to
get results at higher temperatures. But at these temperatures manganese
dioxide and platinum black are almost identical in their effect on the
decomposition of potassium chlorate.
In the near future the study of the action of other oxides at low tem-
peratures will be undertaken in order to get comparative results.
At the beginning of the investigation on catalysis it was believed
that many of the actions would prove to be of a purely chemical nature.
At the present time there is no evidence that such is the case; but
rather that we are dealing with cases of true contact action.

Errect oF Rapium on ELgctTroLytic Conpuctivity.
By RYLAND RATLIFF.
The material used was one-tenth of a gram of “Curie” radium
chloride of 10,000 strength placed at the disposal of the writer through
the kindness of Dr. Foley and the other Indiana University authorities.
A number of the usual experiments were first performed to test the
quality of the material. These included photographing the fiuorescent
action of the radium upon small diamonds and Wilhemite. In these
and kindred experiments good results were obtained.
Two attempts were made to obtain a photograph of the spectrum by
means of the Rowland concaye and Brashear mounting. In the first
exposure of 90 hours the radium chloride was placed directly in front of
the slit which was made unusually wide (probably too wide). A second
exposure of 162 hours was made by placing the radium slightly to one
side of the slit and the fluorescing Wilhemite directly in front of it. In
this trial the slit was made narrower but was considerably wider than in
ordinary spectrum work. Neither exposure yielded any effect other than
a slight fogging of the plate. The remainder of the work was devoted
to the problem, as above stated, of determining the effect upon elec-
trolytiec conductivity.
The apparatus employed is represented diagrammatically in Fig. 1.
Glass tubes I and II filled with the electrolytic solution are intro-
duced into the two arms of the Wheatstone bridge BD and CD. The
copper disks d, and d, are placed as nearly as possible the same distance
apart as d, and dy. Then when resistances R and R, are made the same
the bridge will of course be balanced approximately. R and R, were
usually made of from 800 to 1,200 ohms each. With the bridge balanced
the radium is placed as near as practicable to I or II and the direction
and amount of deflection in each case is noted.
Theoretically the back E. M. F. should be the same in each tube,
but it was found to be impossible to get it so in practice for any con-
siderable time. Hence the greatest difficulty in the way of definite posi-
tive conclusive results is due to the drift of the needle. A Rowland D’Ar-
sonval galvanometer with a sensitiveness of one megohm was em-
ployed in the major part of the work.
110
The tubes were first filled with an almost saturated solution of Cu
So, On working for two days with this electrolyte trying many different
adjustments it was found that the back or electrolytic E. M. F. was so
variable that no reliable results could be secured. The only thing deter-
mined positively was that lengthening the distance between the disks
in I caused a deflection E, and lengthening that in II produced a defiec-
tion W.
On filling the tubes with pure distilled water the results were some-
what more definite. With the disks 14 cm. apart the following data

II gave deflection (E) to 343. On removal deflection was W.
Since an E deflection indicates a decrease in the resistance of IT
the first results secured seemed fairly definite. To make sure the move-
ments were not due to the Ww. M. I. of the electrolyte, weights were
placed on the keys by which the battery and galvanometer circuits were
both kept closed for a considerable time until the needle had ceased to
drift. Four additional readings were taken, the five sets of readings
being as follows: in all the lists of readings deflections indicating a
decrease of resistance by the presence of the radium are marked +,
those indicating an increase are marked —:

Two drops of H.S O, were added to the water with which ‘the tubes
were now filled. This of course greatly increased the conductivity. It
also made it much more difficult to balance the bridge. In securing the
data given in table II the radium was placed alternately upon the two
tubes, N and §8.

It was observed that with a given adjustment the drift of the needle
was often tolerably constant, and, for a considerable period in the same
direction. Sufficient additional resistance was now introduced at R, to
cause the needle to drift in the opposite direction so that the influence
of the radium would be exerted against the drift.

A solution of AgNO, was next used as the electrolyte. The Ag and
Cu made a battery to such a degree that no consistent results could be
obtained. A considerable amount of Ag was deposited on the Cu elec-
trodes. Evidently a very dilute solution would be more likely to give
results. The most satisfactory solution used was made by diluting 3 ee.
of the Cu SO, solution used at first to 100 ce.

Several of the lists, especially Table VI, show the effect of the drift
of the needle. .
A number of efforts were made to overcome this difficulty, none of
which were entirely successful.
One entire day was spent trying to get data for a curve which would
show the influence of this ever present but very variable factor. In the
first four readings of Table VII the drift was taken every five or six
minutes and the succeeding readings were with the fadium, readings
every minute.

If the average drift was really no greater than that obtained when
special effort was made to determine its amount it was not sufficient to
balance the considerable excess of positive readings.
Summary: Of the total number of readings, 61 per cent. indicated
positive results, 26 per cent. were negative, and 13 per cent. were zero,
i. e., gave no deflection. Of the total amount of the deflections (omitting
the rather questionably large ones in Table I), 82 per cent. were positive
and 18 per -cent. negative. Including those of Table I, 90 per cent. were
positive.

A Srvexte Metuop oF MEAsuRING ELECTROLYTIC RESISTANCE.
By R. R. Ramsey.
In measuring the resistance of electrolytes the back e. m. f. or
polarization of the cell is always a troublesome source of error. The
potential of the terminals of an electrolytic cell is never the same unless
the temperature, concentration, and purity are absolutely the same at
both electrodes. To avoid this error various methods have been used,
such as the alternating current and telephone method.
While working with electrolytic cells it occurred to me that the
ever-present and troublesome e. m. f. might be utilized in a very simple
manner for resistance measurement. This method consists of placing the
Figure 1.
cell in series with a resistance box and mirror galvanometer and taking
readings of the galvanometer deflection with several resistances in the
box. From these readings the cell resistance can be determined by
solving for Re in the two equations,

CONSTITUTION.
ARTICLE I.
Section 1. ‘This association shall be called the Indiana Academy of
Science,
Sec. 2. The objects of this Academy shall be scientific research and
the diffusion of knowledge concerning the various departments of science ,
to promote intercourse between men engaged in scientific work, especially
in Indiana: to assist by investigation and discussion in developing and
making known the material, educational and other resources and riches
of the State; to arrange and prepare for publication such reports of inves-
tigation and discussions as may further the aims and objects of the Acad-
emy as set forth in these articles.
Whereas, The State has undertaken the publication of such proceed-
ings, the Academy will, upon request of the Governor, or of one of the
several departments of the State, through the Governor, act through its
council as an advisory body in the direction and execution of any investi-
gation within its province as stated. The necessary expenses incurred in
the. prosecution of such investigation are to be borne by the State; no
pecuniary gain is to come to the Academy for its advice or direction of
such investigation.
The regular proceedings of the Academy as published by the State shall
become a public document.
ARTICLE II.
Section 1. Members of this Academy shall be honorary fellows, fel-
lows, non-resident members or active members.
Sec. 2. Any person engaged in any department of scientific work, or
in original research in any department of science, shall be eligible to active
membership. Active members may be annual or life members. Annual
members may be elected at any meeting of the Academy; they shall sign
the constitution, pay an admission fee of two dollars, and thereafter an
annual fee of one dollar. Any person who shall at one time contribute
12
fifty dollars to the funds of this Academy may be elected a life member of
the Academy, free of assessment. Non-resident members may be elected
from those who have been active members but who have removed from the
State. In any case, a three-fourths vote of the members present shall elect
to membership. Applications for membership in any of the foregoing
classes shall be referred to a committee on application for membership,
who shall consider such application and report to the Academy before the
election.
Sec. 3. The members who are actively engaged in scientific work,
who have recognized standing as scientific men, and who have been. mem-
bers of the Academy at least one year. may be recommended for nomina-
tion tor election as fellows by three fellows or members personally ac-
quainted with their work and character. Of members so nominated a
number not exceeding five in one year may, on recommendation of the
Pxecutive Committee, be elected as fellows. At the meeting at which this
is adopted, the members of the Executive Committee for 1894 and fifteen
others shall be elected fellows, and those now honorary members shall be-
come honorary fellows. Honorary fellows may be elected on account of
special prominence in science, on the written recommendation of two mem-
bers of the Academy. In any case a three-fourths vote of the members
present shall elect.
ARTICLE III.

EARLY INDIANA PHYSICIANS: When the pioneer came to our territory
he left his old diseases behind, but in the course of time they followed
him, and he had to make the best of it. Until a country is sufficiently
settled to support an educated physician, none comes in. Men were in-
fluenced then by the same motives that influence them today. No well
educated physician today thinks of settling in the backwoods; but as soon
as a settlement 1s made and a village arises, some venturesome spirit is
apt to come in. As a matter of fact the first Indiana physicians were mea
connected with the United States army posts along the Wabash river, little
over 2 century ago; unfortunately they left no records of their observations.
Physicians proper began to come in during the first decade of the past
century, but there are scarcely any medical records prior to the year 1820.
The early physicians led a strenuous life; there were no roads and the
sick were scattered over a large area: it was a horseback and saddlebag
life. Few had time or inclination to write—to the few who did write we
owe all our knowledge of those days. Medical books then were few and
costly; a man with one book in each branch of medicine was indeed a
rarity. Medical journals were equally rare, and the fact that some of
the early Indiana physicians took the London Lancet speaks volumes for
their learning and ambition.
The educated physician soon had apprentices; that is, farmers’ sons,
who learned the rudiments of the profession and then began their own
work; few went to a medical school. Wor a long time there were only two
medical, schools this side of the Alleghanies—at Lexington, Ky., and at
Cincinnati—and to attend these meant a long trip over roads at times
almost impassable. At first there were simple medical laws, but these
were abolished, and after 1848 the field was open to all. Just as bad
money drives out the good. so bad physicians drove out the good, or pre-
vented good ones rrom coming in, and for a long time medical affairs went
backward. But we inust not forget that Indiana retrograded generally
during this time. In 1850 Indiana was the eighth State in point of number
lower than all the
of inhabitants, but ranked twenty-third in illiteracy
slave states but three. The term ‘Hoosier’ was a term of reproach, from
which our physicians did not escape, and sharp criticism was passed on
some of our civil war surgeons.
The early Indiana physicians had few kinds of diseases to contend
with, but these few made up in number of enses for the lack of kind.
Malaria ravaged frightfully and dominated all diseases. The standard
27
treatment for malaria, as for most other diseases, was bleeding, purging
and vomiting, and the use of calomel, whisky and bark, the latter in time
displaced by quinine.
In the course of time the pains and aches of civilization came in. I
have heard old settlers speak of them as ‘“new-fangled diseases,” and
there came also a revulsion against old methods of treatment. In the
absence of restraining medical laws, a host of practitioners soon appeared ;
some of these becume quite skillful, but one is reminded of the story of
the man who eapressed his admiration at the skill of the oculist who had
just operated on him; the oculist admitted that he was skilled, adding,
“But L£ spoiled haif a bushel of eves in learning to perform that operation.”
Gradually the “isms” and “pathies’” of medicine appeared, most of
them a protest against some of the absurdities of the old practitioners.
There are no “isms” nor “pathies” among the sciences on which medicine
rests—anatomy, baclericlogy, chemistry, and so on, are free from then:
but when it comes to therapeutics or treatment, one-half of the doctors
think the other half wrong. However a number of established facts are
gradually accumulating and in the course of time there will be a science
of therapeutics, in which serum therapy will, no doubt, bold a prominent
place, and many of the drugs of today only a minor one.
With the advance of civilization a number of well defined diseases
tend to diminish, but with a massing of humanity a host of ills tend to
increase. There are any number of affections that scarcely rise to the
dignity of a disease. Prescribing becomes largely a prescribing for symp-
toms, and many of the sick do their own prescribing ; some go to a physician
only as a last resort. Many are unwilling to pay the physician for the
time it takes to investigate, and so the physician himself simply prescribes
for the symptoms. Some physicians are so busy doing this that they have
no time for study or to attend the meetings of their medical society, much
less attend and take part in the deliberations of any scientific society. The
bane of the scientific physician is the busy practitioner who flits from one
patient to another, never studying any case in detail nor taking time for
study, or manifesting any interest in the progress of medicine. The number
of men who have contributed to the annual Transactions of the Indiana
State Medical Society is remarkably small; where a few make frequent
contributions, many make none at all.
Mepicar. ScHoonts: For a long time our State had no school for the
education of physicians and the more ambitious students of medicine had
28
to go elsewhere. More than fifty years ago the doctors of Indiana were
discussing the advisability of establishing a medical college; there were
arguinents pro and con. Sole believed that if we could not have a good
school, we had best have none. Since then many medical colleges have
come into existence and continued for variable periods of time. Some
“went under” early, others experienced the hardships of existence as
private institutions. ‘The struggle is still going on. Indiana is behind the
times; she is still without a medical school controlled by the State. Every
civilized country sooner or later is con:pelled to assume control of medical
education.
The art of medicine has made progress in Indiana, but the science
lags behind; so far, our State has made little real addition to the science
of medicine.
Although at the time of the passage of the common school law, only
about fifty years ago, the term Hoosier was one of reproach, the advent of
the schooimaster and State education soon changed that, and today we
take pride in being called Hoosiers—it is becoming a term of honor rather
than of reproach. We have wholly outgrown our former reputation, and
Indiana literary productions are Known the world over.
The old medical schools did their work well; it was a practical work;
but until the State takes charge of medical education and sets a good
standard, little advance in medical science is to be expected.
Art precedes science everywhere. Our own physicians have been so
busy applying the knowledge already extant that they have not had time
to make original observations. and few have published their observations.
But the time will come when our physicians will add to the scientific litera-
ture of medicine—the rise of general education and of literature in our
State foreshadows it.
THE ADVENT OF DISEASES.
The coming in of new diseases can perhaps be best understood in the
light of the analogy of the coming in of new weeds. Weeds and diseases
can be compared in many ways, but after a time analogies fail and each
must be studied separately. Pointing out analogies often leads men to
think, and in this tight they are justifiable.
Harty Boranists AND HAarRLY WEEDS—HARLY PHYSICIANS AND HARLY
DISEASES: Of the prevalence of the early weeds of our State we know
29
but little; there were no competent observers. A farmer might fight weeds
all his life and yet know but little about them, about their characteristics
and properties, or their classification, and he is very apt to confound species.
A farmer usually simply learns to do certain things, only a few inquire
into the reason why or into the nature of the thing itself; we call these
few progressive farmers.
The erratic Rafinesque was perhaps the first botanist who visited our
State, but he left no records of Indiana plants. The first botanist to make
a local list was Dr. A. Clapp, of New Albany, in the early thirties; at that
time inany European weeds had already wandered in. Since then a num-
ber of local lists have been made, some of them by physicians who botan-
ized as a recreation. The first State Catalogue was that of Coulter, Barnes
and Arthur, published in 188!. The complete State Catalogue of Stanley
Coulter did not appear until 1900; since then a number of additional lists
have appeared in the Proceedings of our Academy. New plants are con-
stantly arriving, brought in from other States and countries; of these new
arrivals many are weeds and of these some remain and become common.
Where at first there were but few observers of new arrivals, now there are
many, and new weeds are soon recognized and reported.
If it requires a botanist (even though only an amateur who submits to
the superior knowledge of the expert) to distinguish between weeds, it
must be evident that an educated physician is required to distinguish be-
‘tween diseases and to record the arrival of new ones. A man may fight
disease or diseases all his life without knowing anything about Das Wesen
der Krankheit; indeed, it is painful to admit that the best physicians have
to fight diseases about whose real nature they know but little; like the
farmer and his weeds, they can simply fight them in the way they have
been taught or have learned how. Unfortunately the routinism of some
physicians is on a plane little above that of the farmer’s method; they are
satisfied to live on without making any effort to find out and we do not
look for any advance in learning from them.
The advent of the educated physician has already been referred to, so
I shail proceed to give a few analogies between weeds and diseases. My
remarks, as already mentioned, will be suggestive rather than exact scien-
tific statements, mere outlines without dates. Of the many introduced
diseases I can inention but a few. Animals and plants also have diseases
but I shall refer only to disease in human beings.

ANALOGLIES OF WEEDS AND DISEASES.
THE Days or Few WEEDS AND OF LirrLe DISEASE: The first settlers
cultivated only small patches of ground, often only a “truck patch”; there
were few kinds of weeds and these were natives and easily destroyed.
The Kagweed (Ambrosia artemisizfolia) was probably the chief among
them.
Of the diseases of the native Indians at the time the white man first
came among them, we know nothing, but we do know that their life was
not conducive to the evolution and propagation and dissemination of dis-
eases, and we cau assume that, in all probability, they were practically
free from disease. Men who live in isolation, and in proportion as they
do live in isolation, are almost free from the common pus formers, the
Staphylococci and Streptococci, with an absence of many of the common
ailments of life dependent more or less on them.
‘Thg early settlers wére a hardy set of men and women; they had left
their weak and feeble behind, and they led a happy life, especially in the
northern part of the State where the Indians were not savage or warlike,
owing mainly to the influence of the French pioneers. There were few
weeds and likewise few diseases; they had left both behind. But they
found at least one native disease, namely milk sickness, or in other words.
they found the cause of it, and when this got into the body, through the
use of infected milk or the flesh of cattle with the trembles, a reaction
came on, and this reaction was called Milk Sickness—a disease about
which there has been much discussion.
THe Days oF Dog FENNEL AND JIMSON WEED—OF MALARIA AND Ty-
PHOoID Fever: The Dog fennel came in early, from Europe. Jimson is a
corruption of Jamestown, the early colonial settlement in Virginia. Both
weeds flourish in neglected places, on farms, in villages and in towns;
they disappear with the advance of progress and civilization. On clean
but
farms and in clean villages and towns we see no Dog fennel today
there are still Dog fennel towns in Indiana.
Malaria and Typhoid fever may appropriately be compared and con-
trasted with these two weeds; both were brought in by the white man.
Pr
Malaria came first and was known as “The Fever.” When typhoid fever
came in it was called “Continued Fever,’ to distinguish it from malaria
also known as “Periodical Fever.’ Until the decade 1840-1850, physicians
the world over were not able to clearly differentiate typhoid fever, it was
OL
long coufused with typhus fever; very recently another disease has been
differentiated, known as paratyphoid. Thus finer and finer distinctions are
being made. In this connection I might refer to the analogous case of
the plants Scrophularia nodosa, Scrophularia Marylandica, and Scroph-
ularia leporella. and how the latter, a native Indiana plant, was for a long
time confounded with the other, just as that in turn had been confused
with the European form—a botanist will readily understand this simple
allusion.
Malaria and typhoid fever both flourish under simple and primitive
conditions, that is, under a neglect of sanitation. Malaria flourishes
where the Anopheles mosquito breeds and is transferred from one indi-
vidual to another by its bite. The drainage of wet places and the use of.
quinine are the chief factors that account for the subsidence of malaria
and its present rarity. Typhoid fever differs markedly from malaria!
fever in that one attack protects the individual. The weak are killed off
and those who survive are immune (second attacks of the disease being
rare) and this fact has an important bearing. Typhoid fever is chiefly a
water-borne disease, especially well water. Where wells and closets are
close together or where the subsoil is porous, diffusion takes place. In a
family where typhoid fever occurred there may be no further difficulty
from the use of the well water, but any stranger or visitor using it may
fall a victim. Im cities dependent on wells there may be much typhoid
fever, while on the other hand a city with a good municipal water supply,
especially where the water is properly filtered, may have little of it. Cities
dependent on a river supply without previous filtration may fare very well
so long as the water is clear, but with the muddying of the river after a
rain and with a resort of the citizens to the old wells, there may be a
constant recurrence of the disease. In this connection we must not forget
that many of our rivers are today nothing but open sewers full of infec-
tious germs.
Malaria has disappeared from the cities (the Anopheles mosquito does
not live in cities) but it still flourishes in backward, undrained, communi-
ties—communities that are still in the Dog fennel days. On the other
hand, typhoid fever is all too common in some of our cities and towns—
another indication of the survival of Dog fennel days.
Not so very long ago the chief diagnostic character for distinguishing
between the two diseases was the fever, that is the elevation of tempera-
ture, but every now and then so-called atypical cases occurred which left
32
the diagnosis a matter of doubt. ‘Today the scientific physician takes a
few drops of blood from the finger of the patient, one drop he examines
for the malarial parasite, the other is used for making the serum test for
typhoid fever. In the one disease a few large doses of quinine usually
cures outright; in the case of typhoid fever little medicine is given, little
being required; with good nursing, proper diet, and an abundance of pure
water and pure air, the patient is apt to recover. Although formerly no
exact diagnosis was possible, yet the treatment of cases was simple; qui-
nine, whisky, calomel and opium were standard remedies. Little atten-
tion was given to hygienic measures, the sickroom was often tightly closed,
with the exclusion of fresh air, and as a consequence there was bronchial
irritation, often bronchitis. Typhoid fever is not the fatal disease it was
considered to be in the early days, and the nurse has largely taken the
place of the doctor in the treatment.
In the early days of Indiana, bleeding was in order in the treatment
of malaria, but this practice soon declined. Although the proper remedy
is quinine, yet for a long time it was given in insufficient dosage. Just as
too little water can be put on a fire, and fail to put it out, so too little
quinine can be given to cure a patient—and if you wait too long the fire
(or the disease) may become very destructive. It was customary to “pre-
pare the patient for the quinine.” Some died before the preparation was
completed. The discovery of the Plasmodium malaria, the active cause
of the disease, was a great advance in medicine. But to look for the
parasite is not universal today; some physicians find it easier to prescribe
before they are sure of the diagnosis—Dog fennel days still survive.
THE Days OF COMMON EUROPEAN WEEDS: The white man in his wan-
derings over the world has brought together a miscellaneous collection of
weeds, and these follow him wherever he goes. ‘Today most of our com-
mon Indiana weeds are immigrants from Europe, where they have resisted
destruction for ages. The Amaranths and Chenopodiums when cut down
will sprout anew; pulled up by the roots they take fresh hold while lying
prostrate on the ground; if but a single plant ripen seed, the surrounding
country will soon be restocked.
The white man in his wanderings has likewise collected a miscellan-
eous lot of diseases, and these, like his weeds, follow hIm wherever he
goes. A list of their names may be found in the daily mortality statistics
in the newspapers or in the advertisements of patent medicines.
a "ee
33
Man fights his common diseases by resorting to the use of medicines,
especially patent medicines; he has not yet learned that diseases, like
weeds, may be eradicated, or that prevention is easier than cure. An in-
telligent farming community is apt to make a combined attack on weeds,
and the less seed scattered about the fewer weeds there will be. Perhaps
after a time we will go after diseases as the good farmer goes after his
weeds; indeed, we have already reached the stage where we keep a look-
out for such formidable diseases as the plague, cholera, typhus fever and
several others; we do not allow them to land. But we are so accustomed
to some diseases that have already landed and that have gotten a foothold
among us, that we seem to have forgotten that we could get rid of them
if we only tried.
Among the diseases once common in civilized Europe but now becom-
ing more and more rare, may be mentioned leprosy, cholera, plague, typhus
fever, miliary fever, scurvy, smallpox, malaria, typhoid fever, and others.
Some countries are even beginning to show a reduction in the number of
deaths from tuberculosis, and some cities regard the presence of much
typhoid fever as a municipal disgrace. Man’s control over the spread of
diseases is becoming more and more marked.
THe ANALOGY OF WEEDS AND DISEASES CARRIED FURTHER: A botanist
‘an take his manual and check off plants, especially weeds, that are spread-
ing or migrating, and confidently look forward to the time when they will
appear in his own locality. ‘Those who are on the lookout for new weeds
are rewarded every now and then by finding new arrivals. The date of
many arrivals is known. New weeds are introduced in impure garden
seed, or in the packing of crates or boxes; some travel by rail, others by
water. Some come to stay for but a single season; they may find the en-
vironment unfavorable, early or late frosts may be detrimental; some live
for a few years and then die out; a few, however, may find conditions
favorable and ilourish to such an extent that they may be seen everywhere,
and a man who did not know of their introduction might be led to con-
clude that they always grew in the locality. The list of naturalized weeds
in our State is today quite large.
The date of the first appearance of some of our diseases is likewise
known, but unless a disease has some marked or striking characteristic, it
is apt to be overlooked. Influenza and cholera were readily identified when
they arrived in our State and the date of their arrival is duly recorded,
3—A. OF SCIENCE.
34
but tuberculosis and typhcid fever came in so quietly and unobtrusively
that no notice was at first taken of them, at least we have no records of
their first appearance. People ordinarily do not reason about these things,
but the early Indiana doctors realized that a change was going on and
long ago the Indiana State Medical Society had appointed a committee
to look into the matter. (In this connection I may say that only last week
I reported to the Cass County Medical Society a case of tropical sprue, or
psilosis, brought into the State by a missionary returned from Korea. New
cases are, however, not apt to arise from it.)
Although there is an analogy between weeds and diseases, the former
growing in the earth. the latter on or in the body, yet diseases are not en-
tities that can be handled and examined. But in the childhood of the race
disease was held to be a thing that had gotten into the body, had taken
possession of it, and the early medicine man tried to drive it out by the
use of all sorts of noises and nauseous drugs, even by torture. ‘The Chi-
nese and Korean medicine men of today are quite expert in thrusting long
needles into the body of the sick; it is really wonderful how little dam-
age they do—they have learned how to avoid the vital spots or organs. In
some other countries the sick are filled up with all sorts of nauseous drugs,
and the physicians are quite skilled in knowing what to give so that the
patient may not die from the effect of the supposed remedy.
A specific disease is now regarded in the light of a reaction of the
organism, of the body, toward some foreign cause, the reaction depending
on the kind of cause. ‘The reaction may be so definite that the disease
may be diagnosed from the symptoms alone, without examining into the
nature of the cause, though diagnoses based on a recognition of the cause
are of course more exact than when based on symptoms.
The classification of diseases a hundred years ago, at the time when
our State was first being settled, was by classes, orders, genera and species,
just as in the case of botany and zoology. Many systems of classification
have appeared, each one supposed to be an improvement over preceding
ones, and physicians are just now working upon a new system which they
believe will stand the test of time. Old systems were based on symptoms,
the new is based on the recognition of the cause of the disease. Thus
Osler’s recent treatise takes up first the diseases due to animal parasites—
those due, in order, to protozoa, parasitic infusoria, to flukes, cestodes,
nematodes, and so on—followed by the specific infectious diseases, from
typhoid and typhus fever running down to tuberculosis and leprosy, in-
30
cluding some whose causes have not been definitely identified, analogy ad-
mitting their inclusion. ‘The reactions or intoxications due to the ingestion
of chemical substances, such as alcohol, morphia and lead, follow, with a
mention of sunstroke—and then all at once there is a classification riot.
For want of something better, a number of diseases are described under
the head of “Constitutional Diseases.” Then follow a host of affections
and diseases that for convenience are grouped under their respective
organs, beginning with the diseases of the mouth and running down the
alimentary tract, followed by the affections of the other organic systems—
the respiratory, the nervous, etc. One-third of the book is thus definite,
based on a scientific system, the rest is simply based on convenience of ref-
erence. Although we have here real progress, yet how much still remains
to be done.
Some of you may recall the story of the amateur botanist who com-
plained to Linneus of the poverty of Sweden in material for study, and
how Linneus placed his hand over a tuft of moss and said, ‘Here is study
for a life-time.” ‘To study diseases we need not go to unexplored Africa,
where so many new and strange diseases are being found; our common
every-day ailments and affections and diseases are worthy of the deepest
study, much is still to be learned about them. Not all is known about
common everyday coughs and colds, about rheumatic and neuralgic aches
and pains, about anemia and fever, dyspepsia and nervousness.
The old physicians diagnosed diseases almost wholly from or by their
symptoms, and they were close observers, with sharpened senses like those
of the Indian. The modern physician relies to a great extent on so-called
laboratory methods, and the influence of the college and university labora-
tories is being felt. Rough and ready methods are more and more being
replaced by refined ones. But we must not undervalue the importance of
simple observations, without the use of instruments, nor should we neglect
the training of the sense organs.
Scientific classifications are for scientific minds, but we must not for-
get that “Nature makes transitions and naturalists make divisions.” Hair
splitting in medical classifications, or nosology, is not unknown. As a mat-
ter of fact each group of specialists has its own system and nomenclature,
and when the average all-round physician takes up one of the special
treatises he requires the aid of a medical dictionary.
Popularly we can classify the diseases of our State, including those
we have had in the past and not excluding those still to come, according
36
to the way in which they are transmitted from one individual to another.
It is perhaps needless to say that diseases are carried from one individual
to another, from host to host, much after the fashion of weeds carried
from one field to another. The seed of a weed may gain access to a field
by being blown in by the wind, or it may have been brought in by an ani-
mal, especially by birds; many weeds have been brought in by impure
garden seeds. Cheat or chess among wheat means that the seed was
present; it does not mean the transformation of one species into another,
nor does it mean a spontaneous generation.
The railways are important factors in the distribution of weeds, as
they are of diseases. Before the days of railways new diseases traveled
slowly, cholera and influenza required a long time to encircle the globe in
their early migrations; today diseases may spread rapidly. In a thinly
settled country, weeds and diseases spread slowly, while the massing of
people in cities, especialiy in the absence of sanitation, favors dissemina-
tion.
Diseases due to specific causes can be grouped in various ways, like
weeds; whether native or foreign: whether coming to stay, or to disappear
after a short time; whether spreading rapidly and then dying out, or
spreading slowly but surely and permanently, etc. Looked at in this light
we might regard Milk Sickness as a native disease which is disappearing ;
Cholera as a disease which has come in repeatedly but on account of un-
favorable conditions never gained a permanent foothold; Malaria as
spreading rapidly and iasting for a long time and then aeclining; Tuber-
culosis as coming in and spreading slowly but surely and not yet having
reached its maximum among us. Measles, scarlet fever, smallpox, whoop-
ing cough, ete., need only be referred to.
CLASSIFICATION OF DISEASES ACCORDING TO THEIR MODES OF TRANSMIS-
SION: In a general way we may Classify diseases according to how they
are carried from one individual to another thus:
1. By direct contact—from one host to another.
2. Transmited through insects. (Notably malaria.)
3. Diseases conveyed by or through food.
4. Water-borne diseases.
5. Air and dust-borne diseases and affections (notably tuberculosis
and pneumonia, with a host of other respiratory affections and a variety
of aches and pains and functional disturbances.)
37
Out of the many diseases and affections that come under one or the
other of the above groups, I desire to make mention of only two, namely,
malaria, already referred to, and tuberculosis—one a decreasing, the other
an increasing disease.
Matarta: Malaria was the Grendel of the early Indianians. Today
we can scarcely realize what the disease meant to the early settlers; in
some localities it ravaged frightfully. Thus in the early history of our cap-
ital city we read that the forest was cleared in 1820 and lots laid out and in
the spring of 1821 the immigrants rushed in to the number of six hundred
or more. In the latter part of July malaria appeared, and, I quote from
Drake, “Before the epidemic closed in October, nearly every person had
been more or less indisposed, and seventy-two, or about an eighth of the
population, had died.” In some localities the disease was so severe that
farming lands could not be solid, and for a long time immigration to our
State was retarded; people went through to Illinois, to the prairies.
In an account of the diseases prevailing in Indiana in 1872, by Dr.
Sutton, it was noted that the summer was dry. and in comparing reports
from differevt counties of the State it was found that malaria had been
more prevalent than usual in some of the rolling southern counties and in
places along streams and rocky creeks, while, on the other hand, it was
less common than usual in the northern counties where before it had been
very common (but where drainage had made some of the worst places sa-
lubrious). At that time the view that decaying vegetation and moisture
had a causative influence was universaily believed, yet that theory did not
explain the conditions. ‘loday, in the light of the role the mosquito plays
in the transmission of malaria, we can readily account for the facts.
In the rolling southern counties many of the small streams are fed by
springs which flow a small volume at all times, but in dry seasons not’
sufficiently to create a current in the rocky creeks; hence many pools
formed, and these pools served for breeding places for mosquitoes. Or-
dinarily even a small continuous current of water will prevent the devel-
opment of mosquito eggs, and we must keep in mind the presence of fish
and insects which feed on the mosquito larva, but which die off in times
of low water, on account of its stagnacy. In the wet northern counties
the drought meant a drying out of the breeding places of the mosquitoes,
with a consequent reduction of the number of insects and of cases of ma-
laria. The same reasoning holds for the increase of malaria along the
larger streams; in ordinary stages of water there may be no stagnant pools
38
or isolated bayous, but such form in time of drought, resulting in a de-
struction of the minnows and the deyelopment of countless numbers of
mosquitoes.
MosqulitoEs: Mosquitoes occurred in immense numbers in the early
days, when breeding places were plentiful. They were common along the
canals, and an English traveler on the Wabash canal, in 1851, writes of
them: “After tea, we all began a most murderous attack upon the mos-
quitoes that swarmed on the windows and inside our berths, in expecta-
tion of feasting upon us as soon as we should go to bed. But those on
which we made war, were soon replaced by others; and the more we killed,
the more they seemed to come to be killed, like Mrs. Bond’s ducks; it was
as though they would defy us to exterminate the race. At last, we gave up
the task as hopeless, and resigned ourselves, as well as we could, to pass a
sleepless night.” He adds: “What with turning about on account of the
heat and trying to catch the mosquitoes, who bit us dreadfully, we did not
get much rest; and we rose the next morning unrefreshed.”
Canals were a factor in the mosquito-malaria problem. In some of the
older States it was noticed that malaria followed the canals, that the dis-
ease appeared where it had formerly been unknown; in other places it
markedly increased its prevalence; some towns were almost depopulated.
When Indiana undertook te build canals the malaria question was not over-
looked; there was opposition. ‘The reservoirs were considered especially
obnoxious, and in places. notably in Clay County, the people began to de-
stroy them; State troops had to be called out to protect the embankments ;
the Legislature even appointed a committee to inquire into the matter and
report. This conimission, and medical men generally, tried to minimize
the supposed evil influence; in the light of the then prevalent decaying-
’ vegetation theory they could not see how canals or reservoirs could in-
crease the disease. Today we can readily see that the popular belief rested
on good foundation; the reservoirs and the small ponds made on account
of the embankments at gulleys or ravines, formed breeding places for mos-
quitoes. The larger ponds in the course of time became inhabited by fish
and thereby lost their mosquitoes. but in the smaller ponds with a period-
ical drying out, fish could not live.
It was noticed that canal-boat men suffered less from the disease than
the people along the banks, and this at first sight seems difficult to explain.
But the explanation is simple; it is analogous to the explanation of why
railway conductors and porters seem healthy in spite of their exposure to
39
infective dust from the coaches, especially the smoking cars. On our rail-
ways today, men who are constantly suffering from the evil effects of in-
haling a polluted atmosphere, manifested by colds and coughs, and ca-
tarrhs, by weeping eyes and noses, and are inclined to be sickly and de-
mand frequent vacations, such men are not long retained in these posi-
tions by the railway managers—-the weeding out process goes on all the
time. Similarly a canal-boat man who was readily attacked by malaria
and who lost much time on account of it, was not long retained in the po-
sition; those who retained their positions were the more resistent ones.
Facts are sometimes explainable by different theories. In the following
story, taken from Drake, the substitution of “mosquitoes” for “whisky,”
as the apparent cause, more satisfactorily accounts for the facts or condi-
tions. It should be remembered that the Anopheles mosquitoes are night-
biters, that ordinarily they fly low, and do not frequent rooms or houses in
which tobacco is smoked.
A few miles to the east of Fort Wayne there was a densely wooded
swamp, known as the Maumee or Black Swamp, which extended on into
Ohio. This swamp seems to have been salnbrious; it was free from ma-
laria, and families who settled in it “enjoyed uninterrupted autumnal
health for three or fout years,” until malaria was brought in by other set-
tlers. In 1838 excavations were made in the eastern end of this wet section
- for a canal. “The laborers, four or five hundred in number, were chiefly
irish, who generally lodged in teniporary shanties, while some occupied
bowers formed out of the green limbs of trees. * * * One contractor
kept a liquor store, and sold whisky to all whom he employed, which was
drank freely * * * the mortality (from malaria) among them was
very great. Another lodged his operatives on straw beds, in the upper
room of a large frame house, made them retire early, kept them from the
use of whisky, and nearly all escaped the disease.”
In this connection it may be said that in the malaria prophylaxis of
Italy, screens on houses, and an avoidance of the mosquitoes outside of the
houses, are of the greatest importance. In our own country the use of
screens in windows and doors is a most important factor in the diminu-
tion of many ailments and diseases that formerly prevailed during the time
of mosquitoes and fiies, cholera infantum not the least among them.
The belief in the injuriousness of night air, still so prevalent among
us, is readily traced to the days of the night-biting Anopheles mosquitoes
filled with the germs of malaria. These mosquitoes do not live in cities, or
40)
at most only in the outskirts. and city night air is really better than that
of the day time, because there is less dust in it.
The widespread use of quinine today is also traceable to the days of
much malaria. Then it was given in almost every case of sickness, a sort
of panacea, and this practice is simply kept up, not only by the people but
by many doctors. Today quinine really has a very limited use. The so-
called “False malaria” of our cities has no relationship to malaria proper ;
it is simply a reaction due to bad air. and not to the plasmodium malaria.
In the early days, when there was but little quinine, and that high
priced, many of the native barks and herbs were used, notably the Dog-
wood, Yellow Poplar, Wild Cherry, Thoroughwort and American Centaury.
They were steeped in whisky and formed “bitters;” bitters still survive
and some are widely advertised in the newspapers; as a rule their value is
nil. A number of other things concerning malaria might be mentioned,
but I must desist and will close this account with a few remarks on Adap-
tation and Immunity.
We know that plants and animals are adapted to their surroundings
and that few can bear any marked change of environment; wet soil and
dry soil plants can not exchange places. nor can tropical animals exchange
places with those of the frigid zones. But many of our cultivated plants
and animals have been shifted about so much that they are able to flour-
ish under a variety of surroundings, just as the white man flourishes be- -
cause he has had such a varied experience in the past. Now there is also
an adaptation in the case of diseases. Where a disease has long been in
4 country or locality, there is a mutual adaptation between the disease and
the people, or in other words, between the parasite and the host. If a dis-
ease is so viruient that it kills off all the people, then the disease in turm
is killed off, or dies out, for want of material. If on the other hand, a dis-
ease is not strong enough to attack at least some members of a community,
then it is apt to be mild and to pick out and live only on the weak and
feeble or aged or the very yoimg, the robust adults escaping. But where a
disease gets among a people who have never had it then it may be very
destructive, many may perish and few survive, but the survivors may re-
people the territory with a stock less susceptible, and we can see how, in
the course of ages, with a killing off or weeding out of the susceptible, a
strain may be produced that is able to live in the presence of the disease.
Examined in this light we get some clew to the original home of ma-
laria. ‘The negro of Africa is quite immune against malaria; there is an

adaptation. The disease producing agent, the plasmodium, is there, and
has been found in the blood of the people without apparently doing much
harm, but when a white man gets into the country he may succumb very
quickly. There may be even a marked difference in white men in their sus-
ceptibility to malaria, or other diseases, doubtless depending on the ex-
posure of the ancestors in former times. The susceptibility of our native
Indians is one of the chief arguments against the indigenous origin of
malaria.
Malaria in Indiana has about run its course, as it has in older civilized
countries; its mortality today is slight—our dog fennel days of malaria
are about over.
TUBERCULOSIS: If malaria was the Grendel of early Indiana, tuber-
culsis occupies that position in our State today. While there has been a
steady decrease in mortality from malaria, there has been a steady in-
erease in mortality from tuberculosis, and we have not yet reached the
maximum. Tuberculosis is an air-borne disease, or, more strictly speaking.
a dust-borne disease, and conditions in our State were never so bad as
today. Although the mortality statistics of tuberculosis are a fair index of
bad air conditions, they do not tell the whole truth; the deaths from a
number of other affections must be included, notably those from pneu-
monia.
Tuberculosis is the slow protest of nature against bad air conditions,
pheumonia is the sudden outcry. The approach of tuberculosis is heralded
by many and repeated warnings—clinicians speak of a pre-tubercular stage,
a stage of coughs and colds, of pains and aches. Pneumonia strikes sud-
denly, without warning. The stranger within the gates of the city has no
time to flee; and to remain in the crowded city is too often synonymous
with death. In the country where air conditions are good, pneumonia is
neither frequent nor very fatal, and under good air conditions tuberculosis
does not thrive at all; indeed, the city victim on going out into good air is
apt to recover, if he goes in time. The ancient Greeks knew the value of
good air, the ponderous volumes of the physicians of a hundred years ago
testify to its value, a value which we are now but rediscovering—we do
not yet fully appreciate it.
We as a matter of course look upon tuberculosis as the great enemy
of the human race—but after all it may be a friend in disguise! Few may
be able to look at it in that light, but some arguments may be made in sup-
port of such a statement.
43
The old herbalists believed that the Creator made no plant in vain;
they believed that every plant had its uses, if we could only find it out.
Looked at in this light the lowly plants that produce disease may have
some use; the cholera bacillus teaches our cities to clean up, and in pro-
portion as they clean up they escape the ravages of the disease. The ty-
phoid bacillus teaches us to look after the purity of our water supply, and
cities and individuals who heed the lesson escape the disease. Perhaps
the tubercle bacillus may teach us to clean up our cities and our homes
and meeting places; it may teach us the use of pure air. But if tubercu-
losis is a friend of the race, it needs watching as fire needs watching; like
it, it may be an exceedingiy bad master.
We must look at the-pre-tubercular stage in the light of a warning
to get out of the dusty and smoky city; the aches and pains and the coughs
and colds may subside very promptly in good air. If the individual re-
mains in the city the disease sets in in earnest, to attack the lungs, and
then it generates hope, and the victim wants to be up and about. And
he should héed the additional warning before it is too late; he should not
lie about the house or the dusty city; he should go out into “God’s green
country” and into the sunshine and pure air.
When a man has an acute alimentary tract affection, not to say dis-
ease, nature takes away his appetite and makes him gloomy; he lies about
and refuses food, thus imitating the lower animals; if he persists in eat-
ing she sends a violent pain and he will probably desist. Nature wants no
food and no work to do with an impaired alimentary tract; she wants
rest, just as a broken bone wants rest to repair the damage. Men who heed
the warnings of nature, the little aches and pains that tell them to do
this and avoid that, are apt to live longest; the chronic invalid who takes
care of himself may live on to old age, while the so-called strong or robust
man who never has an ache or a pain, no warnings from nature, may go to
pieces all at once and prematurely.
The aches and pains of the pre-tubercular stage of consumption should
be heeded, and the hope generated by the disease itself should be acted
upon; nature is showing the way. The elimination of the imprudent, and
of those not adapted to their surroundings. has been going on for countless
ages. Diseases have killed off our weak, and the process still continues.
Our Indians scarcely came within the range of disease elimination; their
life was not conducive to the propagation of diseases, certainly not of tu-
berculosis. When the white man brought in tuberculosis the Indian was
44
scarcely attacked so long as he lived under old time conditions, an active
out-door life; but when he tried to live under white man’s conditions, in a
fixed home, he promptly began to fail and is still failing—just as the negro
fails when he crowds into the cities, and as the Italian fails who comes to
our cities from the pure air of his mountain home. We may say the Ital-
ian is degenerate, that he has no stamina, but that does not explain his
susceptibility, no more than to say the Chinaman is degenerate because he
can live under filth conditions that the white man can not bear. The Jews
coming from the old European cities, where their ancestors have for a long
time lived in the ghettos and under extremely unsanitary conditions, are
quite resistent to attacks of tuberculosis; they are simply the survival of
the fittest ; the Jew whose ancestry goes back to the open country, to a pure
air life, can not hold up alongside the other, for his ancestors have not un-
dergone the elimination process.
Tuberculosis is a protest against bad air conditions. We ought to be
the healthiest and strongest people on the face of the earth; land is abun-
dant and fertile, we have no years of famine, men are not tied down as in
the old world; the poor food of Europe and the long hours of toil are un-
known among us; at least there is no valid reason why long hours should
be required. In spite of these conditions tuberculosis is on the increase
among us, whereas in some European cities there is a decrease. Why
should this be so?
if we write out statements of conditions, one line for clean European
cities and another line for American city conditions, and make an equation
by canceling conditions that equal each other, we have left the polluted
air condition or factor; it offsets all our advantages.
Many individuals can thrive in the air of our cities today. others fail;
thousands fail every year. Many contract the disease in the city and go to
the country to die; many die from city diseases, other than tuberculosis
and pneumonia, traceable to bad air conditions.
Shall we let bad air conditions go on, or even get worse, as they seem
to be doing, and shall we let countless thousands die in the unceasing pro-
cess of adaptation to environment, or shall we attempt to modify the ab-
normal! environinent and allow these thousands to live? We are told that
tuberculosis is a curable disease, and that it is a preventable disease. It
is an introduced disease which we have allowed to flourish unhindered. It
is a disease that flourishes only under certain surroundings. We can make

these surroundings unfavorable for the disease; but it takes a combined
effort, the individual is powerless.
Malaria is disappearing because the conditions favorable for its exist-
ence are disappearing; the opposite is true of tuberculosis. Moreover,
quinine both prevents and cures malaria, and pure air prevents and cures
tuberculosis. Whisky and calomel were popular prescriptions for ma-
laria, neither cured; whisky and cod liver oil are popular prescriptions
for tuberculosis today, yet neither cure, neither singly nor combined.
The administration of whisky, or of alcohol in any form, may be fol-
lowed by a sense of well-being in tuberculosis, and in dust infection gen-
erally, and that is the reason why alcoholic preparations are so popular
and so widely advertised as cures. But the sense of well-being is a false
sense of security; to benumb the body and reduce the pain, the pain by
which nature warns us, is poor treatment. As a matter of fact, alcohol is
still one of the great eliminators of the human race; if we are wise we will
avoid using it.
Over fifty years ago one of the pioneer physicians of Eastern Indiana
wrote of the changes he had observed in his community and in the State;
he said: ‘“Phthisis, pneumonia and bronchitis are believed to be on the
increase. Whether this is due, in any degree, to improved modes of living,
such as tight houses, the general use of stoves, a less constant exercise in
the open air, etc., it would be interesting to know.” Today we know. Fifty
years ago conditions in Indiana were quite primitive compared with con-
ditions seen in our cities today, and yet the gradual increase of dust dis-
eases was being noticed. (Tuberculosis in Indiana, page 45.)
(The chart of the evolution of different kinds of dust will explain it-
self.) (Dust chart, page 47.)
Tuberculosis, known also as phthisis and consumption, is among us;
it came in with other diseases; it came in like some of the weeds of the
fields. How soon will we make any attempt to get rid of it?
Our State Board of Health has been and is an important agent in dif-
fusing a knowledge of diseases and of disease prevention among our people,
and the recent establishment of laboratories for identifying diseases and
for testing the purity of foods and drinks is of the greatest importance.
Physicians have been the prime movers in the establishment of these
evidences of Civilization, but it has been a long fight.
I am glad to see several papers on the program of our Academy this
year that bear on the subject of sanitation; there have been some in the

past, and I hope to see.more in the future; perhaps they could be grouped
under a separate head, that of Sanitary Science.
Our Academy has a committee on “Legislation for the Restriction of
Weeds.” The popular conception of a weed is, a plant growing in the gar-
den or field or meadow, of a plant out of place and more or less resisting
destruction at the hands of man. That some plants grow on and in the
human body, and in animals as well, is not so well known. The thought
has suggested itself: Perhaps the scope of this committee could be en-
larged by taking account of the minute weeds of the body. I would like
to see the title of this committee read “Legislation for the Restriction of
Weeds and Diseases.”*
STATH HOSPITAL FOR TUBERCULOSIS.
In conclusion I desire to make a few remarks concerning the establish-
ment of a State institution for the treatment of tuberculosis.
Modern medicine concerns itself more and more with disease preven-
tion, in the individual and in the community. To give relief from disease
and affliction has always been the aim and the practice of the physician,
but so long as the active causes of diseases and the modes of their trans-
mission were unknown, little could be done in disease prevention. The
good Samaritan still has a place, but the physician who today is only a
Samaritan in binding up wounds and who makes no effort to prevent the
infliction of wounds, or who treats diseases and makes no effort to prevent
the propagation of diseases—such a physician does not fully represent
modern medicine.
Modern medicine knows much about disease prevention, if the knowl-
edge were only applied. Intelligence counts for much. The intelligent of
a community often avoid much sickness, whereas the ignorant suffer; some
of the latter are kept in a state of poverty on account of their lack of
knowledge of diseases and disease prevention. As people become better
educated in sanitary science and in hygiene, they will require more of their
physicians. The high school graduate who has studied the human body in
health and in disease is not apt to be a purchaser of quack medicines, or to
consult an ignorant physician. much less one who has to herald his ae-
“On the day following this suggestion, the chairman of the above committee made a
motion to enlarge this committee by adding two men who #re physicians and changing the
title as suggested; the motion was carried without a dissenting voice.
49
complishments in advertisements in the newspapers. Much is to be ex-
pected from the teaching of sanitary science in our schools.
Since it was discovered that tuberculosis is a curable disease, a num-
ber of countries and States have established institutions where such sick
ean be treated. Germany leads in this work. Some of the institutions are
tent colonies in the forests. Out-of-door life, plain food and drink, pure
air, little or no medicine, that is all that is required. The nostrums ad-
vertised in the newspapers are of no value. Nature simply needs a chance
to correct the difficulty. When the disease has once fully taken hold, little
is to be expected from any form of treatment, and only too often the real
nature of the disease is not recognized until it is too late. It is possible
to recognize the early stages of tuberculosis, and that is the time for be-
ginning treatment; beginning in the pre-tubercular stage is still better.
With fiames bursting from every window, we do not look for the firemen
to save the building, but we rather expect it of. them when they arrive at
the stage of much smoke and a tiny flame.
There are at least 25,000 individuals afflicted with tuberculosis in our
State today, and 5,000 die annually in Indiana from this disease; in addi-
tion many die from pneumonia and other respiratory diseases, and of af-
fections dependent on a polluted atmosphere. Shall we imitate Germany
and a number of our sister States and attempt to save these lives, or shall
we let disease elimination go on unhindered? Sooner or later the process
of elimination will reach our own families, it may reach us individually.
But, you may say, it will require an immense institution to take care
of so many sick. So it would if all were to be admitted, but we can at
once exclude those who are mortally ill and who can not recover, and if we
also exclude those who are able to pay for treatment at a private institu-
tion, the number would be considerably reduced. We need scarcely con-
sider the argument that if the State allows its citizens to get sick from
preventable disease, it should also take care of those sick.
As a matter of fact many institutions, even State institutions, can not
take care of more than a hundred, or at most a few hundred of the acutely
sick. What then, you say, is the use of attempting to save the few and let
the many perish? That is one way of looking at it. But if we look ata
State Hospital as being a school for missionaries in the cause of pure air
and right living, we get a different conception of the problem. It is not a
question of saving a few out of the many lives now going to waste and

leaving behind a trial of desolution, but it is a question of trying to bring
about a change, in arresting the increase of the disease in our State. Every
man and every woman who returns from such an institution would be a
missionary in the cause of pure air and right living—and we need such
missionaries more than do the heathen.

A Strate Natura, Park.

FRED J. BREEZE.
Primeval Indiana has passed away. The great forest-covered plains
are now bare, and divided into cultivated fields. The wild animals, like
the bison, bear and deer, have gone with the forests; while numerous
species of birds and other small animals have also disappeared. Our
streams have lost their purity and wild beauty; some have been fouled
with sewage, while others have been dredged and straightened into arti-
ficial drainage channels. Thousands of marshes and hundreds of lakes
have been drained, and cultivation of the soil has destroyed thousands of
the smaller forms of plant life.
Not all of these changes are desirable, neither are they all necessary,
yet the destruction of natural features will continue; and it seems that
the time is not far away when Indiana will be nothing but a vast expanse
of farms and cities, and man, having humanized everything, will be sur-
rounded by a surfeit of artificial features, the only fauna and flora being
the domestic animals and plants.
Some intelligent work ought to be done to stop the useless destruction
of the wild forms of nature. Many natural conditions still existing ought
to be preserved, and others now gone but still redeemable ought to be re-
stored before it is too late. Every farm has some little corner of ground
which is not tillable and this should be given over to nature. Here, trees,
shrubs and flowers may grow in freedom, and birds and small ground ani
mals find safe retreat. Every county should have a small reserve or na-
tural park. Such an area could well serve as a small forest reservation,
as well as a place where a rich plant and animal life could safely exist.
But to maintain an area in which natural or primitive conditions
could exist on a sufficiently large scale we need a natural park under the
control of the State. It shouid be several square miles in area, and should
be in the northern part of the State, so that it might include a lake within
its limits. Its size and shape should make it possible not only to have a
lake, but a stream basin drained by the lake. Into this park should be
placed the wild animals that formerly lived in this State. Here animals
52
and plants could live under perfectly natural conditions. The park could
serve for many scientific purposes. In it the Department of Fisheries and
Game could carry on experiments in fish and game culture. After a few
years it would be the best possible place for a Biological Station. It would
also be just the place for the field meetings of the Academy of Science. It
is not necessary at this time to go into details concerning its character.
management, and purposes, but only to suggest a few of these things.
Such a reserve would be a little part of the “Indiana of Nature” pre-
served for the pleasure and profit of the people for all time to come. If
the members of the Academy become convineed of its value and will co-
operate to educate public opinion toward this end, a State Natural Park
ean be secured within the next decade.

Tue Drarnace AREA oF THE East Fork or Waite RIVER.
CHARLES W. SHANNON.
“very river appears to consist of a main trunk, fed from a variety
of branches, each running in a valley proportioned to its size, and all of
them together forming a system of valleys, communicating with one an-
other, and having such a nice adjustment to their declivities that none of
them join the principal valley either at too high or too low a level, a cir-
cumstance which would be infinitely improbable if each of these valleys
were not the work of the streams flowing through them.’’*
Streams are among the most important agencies which give form and
expression to the surface of the land. ‘The study of streams, therefore,
involves to a great extent the consideration of the nature and origin of
many topographic forms—hills and mountains, plains and valleys—and
the changes they pass through.
Every person is familiar with the manner in which the rainwater
that falls is gathered into rills, rivulets and brooks, which unite to form
larger rivers. Every one is aware, also, that streams are turbid after
heavy rain. Yet comparatively few people have thought of the work and
change upon the surface of the land which is done by even the smallest of
the rills and all along the course of the river; nor have they thought that
the smallest rill down the hill slope or along the roadside is adding to the
work of the large streains, or adding to the extent of the drainage area of
the stream.
The drainage area of a stream is the land area which is drained by
the main stream and all its tributaries—and the tributaries of the tribu-
taries.
The drainage area of the East Fork of White River is composed of the
western central and southern part of Indiana, including the greater part
of twenty-five of the ninety-two counties of the State, and a total of about
7,000 square miles, or a little less than one-fifth of the total area of In-
diana. This area is mapped out in full on the accompanying map, with
the exception of a few counties lying to the north of the area shown.
*Tllustrations of the Huttionian Theory of the Earth; by John Playfair.

The geological conditions of the country greatly influence the course
and action of streams. The heavy curved line across the map represents
the southern limit of the ice sheet. Thus this drainage area is partly in
the glaciated and partly in the unglaciated portion of the State. It is in
the unglaciated region that we have the most picturesque scenery. The
entire area, subjected to the processes of weathering and stream erosion
for millions of years, was maturely dissected into a complex network of
valleys, ridges and isolated hills. Over this surface the ice-sheet passed
several times, extending as far as the boundary shown. Its effect was to
smooth off the hills, fill up the valleys and to leave the surface covered
over with a great mass of loose, foreign material from the northern re-
gions. Since glacial times the streams have to some extent removed the
loose material from some of the old valleys and are forming a system of
new drainage in the surface of the drift. Geologically speaking, this glacial
accumulation is of very recent origin and the streams seem to have made
only a small beginning in the work they will be able to perform.
An accurate topographic map of the drainage area would show the
contrast in the physical features of the glaciated and unglaciated portions
better than any other description or illustration that could be given to a
person who had not been over the area to investigate the contrast. In the
glaciated area the contour lines would run in large regular curves and
far apart, showing the smoothness and regularity of the surface. South
of the drift limit the lines would be very close together, with a very wind-
ing course and sharp curves, showing a region of deep, narrow valleys, ir-
regular divides and abrupt cliffs.
In attempting to work out the geographic history of an area whose
drainage has been arrested by the invasion of an ice-sheet, we find that
the story of the life resolves itself into four fundamental parts. First:
What are the topographic characteristics of the area during the pre-
glacial history. Second: What changes took place during the glacial
history. Third: What has happened since the disappearance of the ice-
sheet; its post-glacial history. Fourth: What was the effect produced
by the above events on the unglaciated parts of the area.
It is doubtful if the entire glacial area in Indiana was covered by
the ice-sheet at any one time. At its extreme limit the ice deposited but
little drift; and as a rule there is not a well-defined ridge of drift along
the glacial boundary, though some drift is to be seen—as in Chestnut
Ridge, in Jackson County, and a similar ridge in southern Morgan County.
=
59
From the east border of the river, a few miles below Columbus, northeast-
ward to Whitewater valley, in southern Fayette County, there is a well-
defined ridging of drift standing twenty to forty feet above the border
tracts. Upon crossing Whitewater, the border leads southeastward and is
not so well defined as west of the river, though there is usually a ridge
about twenty feet high.
From the north line of Jackson County, following the boundary around
to the west and south, it is in many places hard to trace as a well-defined
line. The ice-sheet must have been very thin, since the topography shows
little, if any, modification. In many places, however, heavy beds of gravel
and till lie against the hill slopes to the north and east. Many large
granite bowlders are also piled up along the hillsides and scattered along
the streams. In this area in the counties of Hendricks, Rush, Johnson,
Shelby, Henry, Decatur and Randolph. there is a form of moraine known
as “bowlder belts,’ long, narrow, curving strips of country, thickly cov-
ered with large bowlders. Low, winding ridges of sand and gravel parallei
to the ice movement mark the course of a sub-glacial drainage through
Madison, Hancock, Shelby and Bartholomew counties. The longest glacial
drainage channel in the State extends from Grant County to White River,
in Bartholomew, but it is not now occupied by any one continuous stream.
Most of the streams in the glacial area are known as sand and gravel
streams and afford great quantities of sand of economic importance and
an abundance of gravel suitable for road material and ballast. In several
of the counties are overwash aprons in which the sand and gravel are
spread out over broad areas.
The thickness of the drift over the State varies greatly, the greatest
thickness in the State being about 500 feet. While in this area the drift
would be from 50 to 100 feet, there is on the higher points but a thin coat-
ing, but the filled valleys make a higher average. It is the glaciated part
of the area that is of importance from an agricultural standpoint. The
glacial drift is a very productive and permanent soil, and can not be sur-
passed in the production of the cereals, while the bluffs, knobs and hills
of the driftless area are proving to be favorable for the growing of fruits.
The rocks of the State are all sedimentary, and in the area here dis-
cussed were laid down upon the bed of a shallow sea receding to the south-
west. Thus the strata dip gently to the southwest, at the rate of about 20
to 40 feet to the mile.
In the State there are six different geological periods represented—the
56
Pleistocene (no rock outcrop), the Coal Measures, the lower Carboniferous
or Mississippian, the Devonian, the Silurian, and the Ordivician or lower
Silurian. All of these are found in the territory of this drainage area;
and of the twenty-five or more formations as subdivisions of the above-
named periods there are at least eighteen of these found as surface out-
crops in this area. These formations may be listed as follows: Merom
Sandstone-——A massive coarse-grained sandstone lying unconformably on
the coal measures. It furnishes glass-sand and some building stone.
Mansfield Sandstone, the basal member of the coal measures, is a medium
to coarse-grained stone. It is quarried for building purposes and for whet-
stones and grindstones. Coal.—tThis area is just in the edge of the Indiana
coal field. The coal is, therefore, very thin-bedded and is mined only by
r
drifting. Shales—The shales of the coal measures are in many places
from 25 to 40 feet in thickness, and are of value in the manufacture of
cement, paving brick and sewer tile. Associated with these shales in
Martin, Greene, Lawrence and Orange counties are considerable deposits

This consists of a series of thin bedded limestones separated from each
other by shales and sandstones. J/itchell Limestone consists of massive
compact layers of dark blue and gray limestone with interbedded impure
fossiliferous limestone, shales and chert. Salem Oolitic Limestone—The
massive fine-grained stone so well known as a building and ornamental
stone. Harrodsburg Limestone—A very fossiliferous limestone, and also
contains great numbers of geodes and chert in the lower members. Knob-

than 500 feet. This formation has its western outcrop in the eastern half
of Monroe and Lawrence and extends to the east as the surface stone for
many miles. To the present time but little use has been made of this
group, but it is growing to be of economic importance. New Albany Shale.

The Sellersburg and Silver Creek limestones. The former is a white to
gray limestone, rather thin bedded but persistent, stretching from the Falls
of the Ohio, north through Clark, Scott, Jefferson, Jennings and Decatur
counties. The Silver Creek lies beneath the Sellersburg. It ranges in
thickness from 15 to 16 feet in the Silver Creek region to 5 or 6 feet in the
vicinity of Lexington, in Scott County, and disappears altogether as a per-
57
sistent formation in the northern part of the same county. Niagara

istic bed of bluish-green shale several feet thick at the base of the forma-

no rock outcrop.
Triassic to Tertiary, Inclusive—‘The only deposits of these ages
known (with the possible exception of the Merom Sandstone) are some
gravels found on certain high ridges in Martin and Perry counties, and
possibly elsewhere. ‘These are outside the drift area, and above any known
stream deposits of gravel. Taken in connection with the uniformity of
elevation reached by the highest hills, in the Mansfield sandstone area,
the Knobstone area and the Silurian area in the southern part of the
State, it has been suggested by Mr. Frank Leverett of the United States
Geological Survey, that at least southern Indiana was reduced to base
level in Tertiary times. In that case the present and pre-glacial topog-
raphy of Indiana would date from some time in the Tertiary. This Ter-
tiary erosion might also account for the absence of cretaceous deposits, if
any such were ever laid down in the State. Until more study shall have
been given these gravels and their interpretation, the matter of this para-
graph must be considered more as a suggestion than as a demonstrated
fact.”* (See Report State Geologist 1872, p. 188; 1897, p. 22.
The highest point in the State is in the southern part of Randolph
County, which at the highest level is about 1.285 feet above sea level. It
is on this height of land that both the East and West forks of White River
have their source. The C., C., C. & St. L. R. R. (Peoria Div.) passes along
this divide between the head waters of these streams. The West Fork
increases in volume and velocity more rapidly than the Hast Fork, which
reaches its destination by a very winding course. Its length is greatly in-
creased and its slope decreased by its numerous meanders, but it is still a
moderately swift stream. After reaching the unglaciated area the direc-
tion of the stream is greatly influenced by the joint planes in the geological
formations. The main streams of these forks grow farther apart until
they reach Shelby and Marion counties, where they approach each other,

then again turn from one another until, in the western part of Lawrence
and Martin counties, they come nearer and at the southwestern corner of
Daviess County. are united in one stream at an elevation of about 425 feet.
Both forks are fed by numerous tributaries, which produce an intricate
drainage system. In many places the heads of these tributaries approach
each other very closely and have in some cases resorted to piracy. It is ob-
vious from the varying character of the valleys and the terraces which bor-
der them, that both forks suffered many disturbances during the glacial
period. As has been stated, we know that valleys have been excavated by the
streams flowing through them, and it is also true that the terraces beauti-
fying their sides are in most cases due to the same agencies—that is, ter-
races owe their origin to the processes of corrosion, or of deposition, or to
both. Many of the terraces are due principally to the re-excavation of pre-
glacial valleys. In much of the unglaciated area there are marks of sey-
eral well-defined drainage levels. The region ranges in elevation from 150
to 3800 feet; the streams cut down rapidly from the upland, then run off
with a slight gradient through deep valleys with rather flat and compara-
tively wide bottoms and very steep sides, with stepped and sloping terraces
with gracefully bending curves which add much to the attractiveness of the
valieys. The upper terraces are formed by the streams cutting down through
the formations of the original table-lands. The lower terraces are com-
posed of mixed materials of the higher levels. The best examples of these
terraces are in the Salt Creek and Clear Creek valleys, and in the prin-
cipal valley of the main East Fork and its adjacent side valleys. Some
of these terraces are shown in the illustrations.
This entire drainage area affords much for interesting study and ex-
ploration, but, as stated above, it is in the unglaciated portion that is
found the most picturesque scenery. ‘The diversified physical features pro-
duced by the processes of erosion and the weathering of the various geo-
logical formations give a region of rugged and beautiful scenery. Some
of the characteristic and marked scenic points are described below.
“Weed Patch Hill,’ in Brown County, is a high ridge in the Knob-
stone, forming the divide between two of the main branches of Salt Creek.
At its highest point it is a little more than 1,000 feet in elevation. One of
the illustrations gives a view looking northwest from this elevation and
gives an idea of the Knob topography. “Guinea Hills” is a ridge rising to
a considerable elevation, extending in a northeast and southwest direction
through the southwest part of Scott and the northwest part of Clark coun-
59
ties. These hills form the divide between the tributaries of the Muscata-
tuck, one of the chief branches of the Hast Fork, and the headwaters of
Silver Creek, which flows south into the Ohio. It is interesting here to
note that water falling on the high bluffs of the Ohio near Hanover,
and to the north within one ‘mile of the river, does not there flow into the
Ohio, but finds its way into the Muscatatuck and the Hast Fork, and after
covering a distance of more than 300 miles flows into the Ohio at the south-
western corner of Indiana. The “Haystacks” are conical shaped hills
which, seen from a distance, have the appearance of haystacks; these are
plentiful in the central part of Lawrence County. “Rock Houses” are
large openings between and under large rock masses due to undercutting
and the breaking off and tilting of the rocks. ‘‘Honeycombs” are rock sur-
faces in which the softer parts have been weathered out, giving a porous,
honeycombed appearance. These are found in the region of the Oolitic
Limestone and the Mansfield Sandstone. One of the most interesting spots
to visit is the “Pinnacle,” near the town of Shoals, the county seat of Mar-
tin County. Here a high ridge of Mansfield Sandstone, one hundred ninety-
six feet above the level of the stream, terminates abruptly within a few
yards of White River. Large masses of rock that have broken off, lie
around the foot of the ridge in every position. From this point one ob-
tains a good view of the character of the topography of this region. To
the northwest of this ridge the formations have been cut through by dis-
integrating forces, and there has been left standing at some distance from
the head of the tavine a tall mass of sandstone, which has received the
name of “Jug Rock,’ from the fancied resemblance to an old-fashioned jug.
On the upper side it is forty-five feet high and on the down-hill side, seventy
feet high; it is capped with a flat projected layer of harder sandstone. At
the south of the deep-wooded ravine is the “Glen,” an under-cut sandstone
eliff with an intermittent cascade. Across a valley to the north is “House
Rock,” a large sandstone cave, the entrance to which is about thirty-five
feet high, and the main room, with an opening in the top, is very much
higher. It is formed principally by the tilting of large rock masses. The
sandstone in front of the cave is weathered into an elaborate fretwork.
Other points of interest as one goes down along the river are the “Acoustic
Rock,” “Buzzard’s Roost,’ “Hanging Rock,” “Kitchen-middings,” ‘Shell-
bank,” and the ‘“Hindostan Falls.”
In Washington, Lawrence, Orange and Monroe counties the subter-
ranean drainage has an important place. The ground water working along
60
the point planes and on the more soluble parts of the limestones has pro-
duced a great variety of sink-holes, caves and “lost rivers.” The sink-
holes are basin shaped depressions many feet deep, and often hundreds of
feet in diameter, with an opening at the bottom which leads into some un-
derground channel; in some cases the openings have become filled and the
water is held in the basin. In many places a stream runs into these holes,
then by underground passages for a great distance, and again comes to the
surface in the form of springs. Valleys, sometimes two to four miles in
length, are drained through underground channels. This gives rise to a
confusing system of hills and valleys, though a well-defined drainage may
be worked out which in itself is usually made up of sink-holes. There are
many pure water springs in this region and also many springs of mineral
waters. The best known of these are the French Lick and West Baden
Springs, Trinity and Indian Springs. Lost River, a main branch of the
East Fork, through Orange and Martin counties, has many “lost” tribu-
taries in Orange County. The numerous caves and the mineral springs
are described in the State Geologist’s Reports for the years 1896 and
1901-02.
The greater or less degree of uniformity in the volume of the river in
the course of a year is one of its chief physical features and depends very
much on the manner in which the water supply is obtained. The streams
of this area depend for their increase wholly upon the rains, which, oc-
curring frequently and at no fixed periods, and discharging only compara-
tively small amounts of water at a time, except in periods of the heavy
rainfall of several days’ duration, preserve a moderate degree of uni-
formity in the volume of the streams. This uniformity is aided by the
fact that under normal conditions only about one-third of the rainfall finds
its way directly over the surface to the streams, the remaining two-thirds
sinking into the ground and finding its way to springs, reservoirs, or gradu-
ally oozing through at a lower level until the soil becomes drained of its
surplus moisture, a process which continues for weeks and helps to keep
up the volume of the stream. But, on the other hand, man has done a great
deal to destroy the uniformity of the volume. By the removal of the
forests, the cultivation of the soil, and the use of ditches for drainage, a
greater part of the water is at once thrown into the stream and greater
fluctuations occur. Owing to the streams being hemmed in by lofty, ab-
rupt cliffs, which resist the free passage of the swollen streams, and the
velocity being checked by winding courses, greater floods occur from the
same amount of rainfall than formerly.

Sreps IN THE DEVELOPMENT OF A SMOKELESS OITY.
W. F. M. Goss.
1. Whe Presence of Smoke in those cities of our country which are
within easy reach of its soft coal mines is becoming more serious every
year. People are beginning to understand that this smoke which, in earlier
days, was welcomed as evidence of a city’s growth, and of its industrial
prosperity, is, in fact, a source of heavy expense to all of its citizens. The
annual smoke bill of such a city as Indianapolis is, in fact, enormous!
This arises, not from the loss of fuel or heat in the form of smoke, for
that is so small as to be almost negligible, but in the damage which is
wrought by its presence, upon the architectural embellishment of the city.
upon the fixtures and furnishings of its homes, and upon the apparel of its
citizens. Loss also occurs through the extensive use of artificial light
which the presence of smoke euforces, and because of its effect upon the
welfare of those from whom it shuts out the sunlight and takes away the
purity of the atmosphere.
Thus far urban communities have sought to protect themselves through
prohibitive legislation, with the result that while flagrant abuses have
sometimes been abated, the atmosphere of the city as a whole has not ma-
terially improved. It is doubtful if such legislation, unsupported by cor-
rective measures which are broadly co-operative, can ever be made an ef-
fective instrument in the abolition of smoke. The problem is one of many
complications and its solution can only be reached through action based
upon a full understanding of difficulties to be overcome.
2. The Sources of Smoke in cities may be separated into five different
eroups, each of which will require different treatment. They are as fol-
lows: .
1. Large furnace fires such as are employed in metallurgical
processes.
2. Large boiler plants, by which is meant all plants in excess of
500 horse-power.
3. Small boiler plants and small industrial fires.
4. Domestic fires.
5. Locomotive fires.
~l
bo
Accepting this classification as a convenient one for the purpose in
hand, we may inquire as to the process by which the smoke now being
delivered by each of the several groups is to be eliminated.
3. Large Fires Such as Are Employed in Metallurgical Processes.
Except in a few cities, of which Pittsburg is the best type, the proportion
of the total smoke delivered from such fires is small. In the city of Indi-
anapolis, for example, it is exceedingly small. Moreover, the managements
of industries using such iires are, in m:uny cases, finding increased efficiency
in operation by the installation of gas producers which receive the coal and
deliver highly heated gas for use in the furnaces. The gas producer makes
smokeless the process of converting coal into heat. As its use under a wide
range. of conditions will result in economy in operation, no injury would
be done by the prohibition of smoke from all fires which might properly
be served by producer gas, provided a reasonable period is allowed be-
tween the passage of the prohibitive ordinance and its going into effect.
Fires of this group which can not be thus treated in such cities as In-
dianapolis will be so few that their effect will be negligible.
4. Large Boiler Picnts. The suppression of smoke from fires of this
class by the adoption of a suitable automatic stoker, will effect an economy
in operation, hence owners will not seriously object if they are required,
after suitable notice, to so equip their plants. An ordinance requiring all
boiler plants of more than 500 horse-power to be thus equipped within three
years of the date of its passage would not be unreasonable.
5. Nmall Boiler Plants and Small Industrial Fires. Referring first
to boiler plants, it should be noted that the fires of this group are or-
dinarily prolific sources of smoke. Boilers of 100 horse-power or less are
all over the modern city. Generally speaking, no economy can result from
the application of automatic stokers to these small boiler plants and hence
owners can not be influenced to add to their fixed charges in the expecta-
tion of securing a money return. The requirement that such furnaces em-
ploy anthracite coal, coke, or other smokeless fuel, would in all cases work
serious hardship and in many cases it would be prohibitive. The wisest
and most effective course to follow with reference to such fires Is to pro-
vide a satisfactory substitute, then abolish them. So far as such plants are
now employed in the production of power, they can be rendered unneces-
sary through the cheaper and more effective distribution of electrical
power. So far as steam from such boilers may at present be used for heat-
ing they can be rendered of no effect through the supply of heat from a
73
central station. There are, however, in every large city Many minor in-
dustrial establishments, such as dye works, bleacheries and laundries, re-
quiring steam at high pressure, and for these a general system of supply
from a central plant must be provided. That this may be the more readily
accomplished, sach industries should be encouraged to group themselves
within a prescribed area to better accommodate themselves to some reason-
able plan of steam distribution. 'o properly supplant the fires of numer-
ous small boilers now in service, it will be required, therefore, that stations
be established throughout the business portion of the city, capable of de-
livering electric current for power and lights, steam or hot water for
heating, and a limited amount of high pressure steam for industrial uses;
these central plants to be of sufficient size to justify the use of stokers
which will make them smokeless. When by municipal co-operation these
shall have been provided, under conditions which will safeguard the inter-
ests of all consumers with reference to costs, then it will be in order to
prohibit, after a series of years, the use of soft coal under all boilers of the
city, except in connection with automatic stokers.
Small industrial fires other than those under boilers should be sus-
tained by gas drawn from sources hereinafter referred to.
6. Domestic Fires. While individual domestic fires are not the
source of heavy volumes of smoke, their number in any city is large, and
their effect in the aggregate as a source of smoke is as pronounced as that
of any other single group of fires. So long as soft coal can be had more
cheaply than anthracite coal, just so long will there be a desire on the
part of the consumers to employ it in domestic service. Domestic fires
being small, it is impracticable to apply to them effectively the principles
of smokeless firing. A necessary step. therefore, in the development of a
smokeless city is a complete prohibition of the use of soft coal for domestic
purposes. As a preliminary step, two things are essential. Wirst, a sup-
ply of low-priced gas for use in cooking; and second, the distribution from
a central station of large capacity of steam or hot water for domestic heat-
ing.
There are no real problems in the supply of gas for cooking except
such as may grow out of existing franchises. At prices now prevailing.
this form of fuel is much used in cooking and generally is less expensive
for that purpose than solid fuels. Add to this the fact that the cost of
gas to the producer is reduced as the quantity sold is increased, and an
abundant supply at a cost sufficiently Jow to permit all people in a city to
74
use it for cooking, becomes not only possible, but attractive as a means of
economy.
The establishment of ceutralized heating plants of sufficient size to
justify the maintenance of smokeless iires therein, and in such number as
to serve an entire city, constitutes a problem presenting no serious en-
gineering difficulties. Such a system would need to be developed under
sufficient municipal control to insure satisfactory service to all portions
of the city and to guarantee to the consumers of heat a cost not greater
than is required to insure a fair return upon the investment made. Enough
has already been accomplished in heating from central stations to insure
the practicability of such a scheme. While the loss of heat in transmis-
sion is necessarily large, this loss is more than neutralized by the use of
low grade coal in the central station, in the place of high grade fuel now
employed in domestic heating, so that, basing an estimate on the heat de-
livered, the cost should not be greater than under present conditions of
domestic heating. Attention should be called to the fact, however, that
such 2 system would be easily practicable even at some advance in cost,
for freedom from smoke and the convenience of a supply of heat from out-
side sources are matters for which people will be willing to pay.
7. Locomotive Fires. These, in railroad centers such as Indianapolis,
are prolific sources of smoke. Moreover, if soft coal is permitted to be
used in fire-boxes the delivery of snioke from locomotive stacks can not be
prevented. As a consequence. prohibitive legislation in various American
cities has thus far had but little effect in reducing the amount of smoke
delivered from locomotive fires. It is not the fault of the railway man-
agement; it is due to the difficulties which are inherent in the case. There
are, in fact, but two ways out of the difficulty, and the acceptance of either
solution wiil involve railway companies in heavy expenditures and will
entitle them to concessions or direct aid from municipalities. The first and
simplest is to be found in the requirement of all steam locomotives oper-
ating within the smoke limits of a city.to be supplied with smokeless fuel,
that is, with anthracite coal or with coke; the second solution is to be
found in the prohibition of the use of steam locomotives and in the sub-
stitution of electric locomotives within the smoke limits of the city.
The development of either of these plans will involve the establishment
of locomotive terminals upon every road outside of the smoke limits of the
city. by the use of such terminals the road locomotive of an approach-
ing train can be stopped before reaching the city, its place being taken
75
either by a steam locomotive using coke or anthracite coal for its fuel, or
by an electric locomotive which will serve to carry the train on to the city,
and afterward out of the station and across the city to another terminal
where it will stop, its place at the head of the train being taken by another
road locomotive having its usual supply of soft coal. Such a plan has
been put into effect in New York City, and has been settled upon for Wasb-
ington, D. C., where the commissioners of the District of Columbia, on No-
vember 17th, took final action on an order to prohibit the use of any ex-
cept electric locomotives in drawing trains into the new Union Station.
Wxcepting in very large cities, however, the cost of electric transmission
will be prohibitive. It will be far cheaper for railway companies, and
quite as satisfactory to the urban communities, to admit steam locomotives,
provided they are supplied with a fuel which prevents smoke.
It is evident that procedure under this outline with reference to loco-
motive fires must necessarily involve plans extending through a series of
years. An equitable scheme of co-operation between the railroads and
the city must be devised, plans must be made and adopted, and time must
be given for financing and executing them.
In the working out of the general plan described by this brief outline
for the elimination of smoke, many difficulties are to be met and antag-
onistic interests to be harmonized, but there is nothing which, from an en-
gineering point of view, is impracticable, or which can not, as a business
matter, be reduced to a satisfactory procedure. A city, to be made smoke-
less by the measures suggested, would first seek to fix limits defining the
area to be controlled. Within this area would be developed a series of
power and heating plants which would be spaced upon a system of squares
in the business portions, at intervals of a mile or a mile and a half, and in
the residence portion at intervals of two miles. From these several stations
would go out currents of electricity for all power and light needed by the
city. From certain of them steam at high pressure for industrial purposes
would be distributed over the limited areas and from all of them would go
out steam or hot water for heating. By a suitable grouping of equipment
within these stations, those in the residence portions would be made to
serve as heating plants alone and hence would be out of service during a
considerable portion of the year. Eecause of their size and the perfection
of equipment, all would be operated by smokeless fires. All small fires,
which at the present time serve for heating and power in individual build-
ings, would cease to exist, and large fires under boilers of great industries
76
and in furnaces of metallurgical establishments, would be made smokeless
by means which would enhance their economy in operation. Railroad
trains passing through the controlled area would be drawn by smokeless
locomotives, and above and around the city a clear atmosphere would con-
tribute to the cleanliness of ali things and to the comfort and peace of
mind of all its people.

EXPERIMENTAL STUDIES IN REINFORCED CONCRETE.
We Ke EArr:
It was the comfortable assurance of that urbane Roman poet, Horace,
that he had built himself a monument more lasting than brass in the intel-
lectual life of mankind. At the time that he was writing these lines the
Roman engineers were constructing those concrete aqueducts and domes
that have served mankind on the physical side during the time that Horace
had been a source of perpetual delight to the students of classical writ-
ings. Which product will endure the longer is an open question. One
thing is certain, while many persons of exquisite taste may prefer Horace
to our modern writers, all well-informed persons conclude that the en-
gineer of today has surpassed the Roman engineer in the quality and use
of concrete.
The number of recent failures of reinforced concrete buildings, at-
tended with the loss of life of workmen, does not constitute an argument
against the advance of the practice of this new art, but calls attention to
the need of correct theory in design and expert supervision in construction.
Steel for buildings is made under highly technical methods, and a searching
inspection by trained men, whereas concrete for buildings may be formed
by ignorant and unskilled workmen, and may be supervised by foremen
who are mostly inexperienced in the art of proportioning and mixing the
ingredients. Defective material, either of cement, sand or stone, dishonest
skimping of cement and poor inspection, incorrect proportioning, and a too
early removal of the wooden forms from the floors molded in cold weather,
or heavily laden with stored cement and other materials, are sufficient
causes to explain these failures. An increasing number of these may be ex-
pected as time goes on and untrained men who have learned their busi-
ness in other lines of construction, take up the work of building reinforced
concrete structures. The resulting loss of life will no doubt call attention
to the necessity of regulating by proper building laws this new construe-
tion, which has spread so rapidly over the country from sea to sea. In
1902, when the first published results of experimentations appeared in this
country from the Laboratory for Testing Materials of Purdue University,
78 :
one had to go far to observe instances of reinforced concrete. Last sum-
mer in Seattle the writer saw no other type of building in process of con-
struction. At Atlantic City in 1902, when the experiments referred to were
placed before the American Society for Testing Materials, there was no
instance of the use of reinforced concrete in sight. Last summer, at the
meeting of the Society, one viewed the stately and beautiful Marlborough-
Blenheim hotel entirely constructed of reinforced concrete; the replace-
ment of the steel pier by reinforced concrete piles and girders; and the
construction of a new recreation pier of this type of construction. The
growth has been truly marvelous. Not only has the extent of its use in
bridges and buildings increased, but the variety of its application is extra-
ordinary. In a list of constructions in which it is successfully and eco-
nomically used may be included: Retaining walls, dams, tanks, conduits,
chimneys, arches, culverts, foundations, floors for buildings, railroad gird-
ers, highway bridges, pipes, railway ties, piles, stairs and roofs.
At the present time the underlying mechanical principles and the con-
stants of design are fairly well determined, and we wait upon the archi-
tects to express the truth of these principles in a beautiful structure.
While this type of construction associates itself with the broad and simple
wall spaces and low buildings of the Spanish Mission style, with surface
ornaments of tiling and Mosaic, it also lends itself to important modern
civic buildings. The stateliness of beauty of the Marlborough-Blenheim
Hotel at Atlantic City has been mentioned. The Ingalls Building, Cincin-
nati, and the new Terniinul Station at Atlanta, Ga., are other examples.
Without stopping to discuss the properties of waterproofness, fire-
proofness, durability, etc., or the multitude of topics of interest and im-
portance that crowd one’s mind in connection with reinforced concrete, at-
tention will be simply called to the mechanical principles underlying the
construction.
Concrete, like stone, is weak in tension, but strong in compression at a
ratio of 1 to 10. Consequently when under flexure, as in a beam, the con-
crete is not used economically ; for it breaks on the lower side in tension
before the compressional strength is utilized. A beam may be, however,
strengthened, or reinforced, by the insertion of a steel rod in the lower
side of the beam. These rods are usually bent up near the ends of the
beam so as to also reinforce the beam against the diagonal tensional
stresses that occur at the ends, due to the combination of shear and direct
stress.
fee
Before the rod can come into operation during a flexure of the beam,
there must be the necessary adhesion between the concrete and the rod to
transfer the stress to the rod, and bring the latter into action. This ad-
hesion yaries from 300 pounds to 500 pounds per square inch of the sur-
face of the rod, and under favorable conditions is sufficient to develop the
strength of the steel in the concrete. The adhesion seems to be more of a
mechanical action than chemical, and is due to the entrance of the fine
cement into the microscopic pits on the surface of the smooth rods. Many
designers use artificially deformed bars, such as corrugated bars and
twisted steel bars, to increase this adhesion.
In this way a beam is reinforced so that both the concrete in compres-
sion and the steei in tension may be worked to their full value. Any one
who has seen a plain concrete beam broken in a testing machine, and then
has witnessed a test of a reinforced concrete beam, will be first of all
struck by the apparently greatly increased flexibility of the reinforced con-
crete beam, which deflects ten times as much as the plain beam before
showing any visible cracks, and when the load is removed the elasticity of
the steel draws the beam back nearly to its original shape. It is probable,
however, that this process of bending the reinforced concrete beam early
develops very minute ilaws in the conerete which are invisible to the
naked eye, so that it is not safe to count upon a tensile strength of the
concrete in computing the total resisting strength of the beam. Designers
compute the resisting moment of the beam as based upon the compressional
stresses in the concrete and the tensional stress in the steel alone.
The original tests at Purdue University were arranged to determine:
1. The increased strength added by a given amount of steel inserted in
a plain concrete beam.
2. The law connecting the strength of the beam with the amount of
steel.
3. The law connecting the strength of the beam with the position of
the rods in the beam.
4. The value of gravel in reinforced concrete.
To determine these relations a series of concrete beams was made of
first-class materials with rich mortar. In other words, the beams were
earefully made with a combination of one part cement to two parts of
sand and four parts of broken stone. The concrete was probably superior
to that made in the ordinary process of construction. This was proper be-
cause the theoretical laws were being verified, and for that purpose it was
80
necessary to have uniform materials of good quality. The elements of the
strength of the materials entering into the beams were determined first
of all; namely, the conipressive and tensional strength of the concrete, to-
gether with the modulus of-elasticity of the concrete, both in tension and
compression; the adhesion between the cement and the steel; the elastic
limit of the steel; a mechanical analysis made of the materials. Since
the beams were long in span compared to their height, and, therefore, the
shearing stresses were not important. rods of smooth steel were used.
Having determined all the elements entering into the strength of the
beam, and then the tested strength of the beam itself, it next became neces-
sary to formulate a mechanical analysis of the combination of steel and
concrete in flexure, and, with the experience of the tests of the beams in
hand, to derive equations for design and calculation. The truth of these
equations and the validity of the process of the analysis could then be
checked by reference to the tested strength of the beams. These equations
were derived and have been used very largely by engineers throughout the
country in designing reinforced concrete structures.
Engineers as a rule have found it necessary to review their knowl-
edge of mechanics in dealing with reinforced concrete, not that there is
any new principle involved. but the number of factors in the equations of
flexure is greater, and an account must be taken of the relative moduli
of elasticity of the two materials, steel and concrete. Furthermore, the
lack of perfect elasticity of the concrete leads to an assumption of some
other than a rectilinear relation between stress and strain.
Again the neutral axis of the cross section must be determined. Its
location is not simply fixed by the center of gravity of the cross section,
but is controlled by the amount of steel present, the relative moduli of
elasticity of the steel and concrete, and by the position of the steel. The
writer’s equations have followed the usual assumptions of flexure, with the
following special assuinptions :
1. That the modulus of elasticity of concrete in tension and com-
pression is the same.
2. That there is a parabolic relation between stress and strain in the
concrete.
5. That in the earlier stages of the loading of the beam the concrete
earries stress in tension, but later, at higher loads, this tensile strength
may be disregarded.
The equations are somewhat cumbersome, but have been reduced to
81
diagrammatic form in the Transactions of The American Railway Engineer-
ing and Maintenance of Way Association, Vol. VY, 1894, pages 626 and 627.
Empirical equations of simple form are presented in The Engineering Re-
view of Purdue University, Vol. I, 1905.
In calculating the strength of the reinforced concrete beam sufficiently
approximate results can be obtained by omitting consideration of the tensile
stresses in the concrete, and supposing a rectilinear relation between stress
and strain. The moment of flexure is then most simply expressed as the
total force in the steel multiplied by the distance to the centroid of the
compressive stresses. This latter distance is expressed with sufficient ac-
curacy as a fraction of the depth of the beam, this fraction having been
determined by experimental measurement on the tested beams.
Care in all cases must be taken to compute the maximum compressive
stress arising in the concrete under the conditions of the problem, and also
the amount of diagonal tension at the ends of the beams must be computed
and provided for by stirrups, or by bending up some of the rods at the ends.
To conclude this brief consideration of reinforced concrete, a conserva-
tive estimate would include the following principles:
1. Concrete is durable and fireproof when made of the proper aggre-
gate.
2. The strength of combination of steel and concrete may be calcu-
lated with a sufficiently close degree of accuracy.
38. Shapely and beautiful structures may be built of this material.
It is particularly adapted for mill buildings because of the absence of vibra-
tions which are induced in the ordinary type of mill buildings by the
rapidly revolving sjachinery.
4. The cost of a properly designed reinforced concrete building, where
wooden forms are used to advantage, need not exceed more than 5 or 10
per cent. of the cost of mill buildings of the ordinary type with brick walls
and wooden beams of the so-called slow-burning construction, provided that
the concrete may be laid as at present by unskilled labor.

THe Newer HyGIENE.
WILFRED H. MANWARING.
Instruction in the nature of infectious diseases, especially in the means
of transmitting these diseases from one person to another, is required by
law in all our public schools. This law is of great value; for it is only
through the intelligent co-operation of a well-informed public that hy-
gienic and sanitary measures designed to control and stamp out infectious
diseases can be successful. A wide diffusion of this knowledge will go far
to make tuberculosis a thing of the past, and diphtheria and smallpox un-
known.
In obedience to the legal requirement, there are taught, in our public
schools, certain elementary facts regarding the nature of pathogenic bac-
teria, and certain facts regarding the ways in which these bacteria are trans-
mitted from one person to another. These facts in themselves are of in-
estimable value, but they are insufficient.
The presence of bacteria within or upon the human body, the trans-
mission of disease-germs from the sick to the well, is but one of the factors
tending to cause disease. To acquire a disease it is usually necessary, not
only to acquire the germs of that disease, but there must be a lowering of
bodily resistance as well.
Every fourth person in this room is carrying daily in his throat or
mouth virulent pneumococci. Yet he does not acquire pneumonia. And
why? Because there is an efficient defense against this disease in the
healthy human body. Some day this defense will be lowered and pneu-
monia develop. Most soldiers in the Philippines carry in their intestinal
canals virulent germs of dysentery; and with no ill effects, till intoxication
or dietary excesses lower the intestinal resistance. We daily inhale germs
of tuberculosis. Some day, when our resistance is low, we will acquire the
disease.
A knowledge of the body’s fighting power against bacteria, a knowledge
of the ways in which that power can be increased or decreased by heredi-
tary influences and by modes of life, is therefore of hygienic importance.
It should form part of the curriculum of every public school.
83
The body tights disease in many ways. It will be sufficient for hy-
gienic purposes to teach but three of these ways: (i) the method of anti-
toxines; (ii) the method of antiseptics and (iii) the method of phagocyto-
sis.
There ar many diseases in which the symptoms are caused, not by the
bacteria themselves. but by the poisons the bacteria manufacture. Thus,
in tetanus, or lockjaw, the bacteria grow, perhaps unnoticed, at the bottom
of the Fourth-of-July wound on the hand or foot; but the chemical poisons
they manufacture, carried by the blood to the brain and spinal cord, cause
the spasms and convulsions that characterize the disease. In diphtheria
the bacteria rarely enter the body, but grow in grayish-white masses on
the moist surfaces of the mouth and throat. The chemical poisons they
manutacture, absorbed by the tissues, cause the paralysis and heart failure
that characterize the disease.
The body has the power of forming substances that neutralize these
poisons. To these neutralizing substances the name antitoxine has been
given.
This fact is of hygienic importance for two reasons: First, because it
is sometimes possible to assist the body in its efforts to form antitoxines,
by introducing into it antitoxines artificially prepared ; and, second, because
the body’s power to form these substances is modified by mode of life.
A horse that has been repeatedly injected with the poisons manufac-
tured by the germs of diphtheria, grown on artificial culture media, de-
velops enormous amounts of diphtheria antitoxine. A few drops of the
serum of this horse renders harmless large quantities of diphtheria poison.
Through the use of diphtheria antitoxine in practical medicine, the mortal-
ity from diphtheria has been reduced from the 24 per cent. to 40 per cent.
it was, twenty years ago, to the less than 1 per cent. it now is, in well-
treated cases. Overwork, insufficient clothing, improper food, alcoholic ex-
cesses, lack of sleep, and other factors, so lower the antitoxine-forming
power of the body as to greatly increase the dangers from infection.
The second way of hygienic significance in which the body fights dis-
ease, is by the formation of chemical substances that, although they have no
influence on the chemical poisons manufactured by bacteria, have an even
more important property, that of killing the bacteria themselves.
The presence of antiseptic, or bacteria-killing substances in the blood
and tissue juices is easily shown. One has but to mix bacteria with serum
84
:
and test trom time to time, by simply cultural methods,* whether or not the
bacteria are alive. Thus, in one experiment, there were mixed with human
serum typhoid fever germs in such numbers, that every drop of the serum
contained 50,000 bacteria. wo minutes later but 20,000 of these were
alive; at the end of ten minutes, but S00; and in twenty-five minutes, they
were all dead.
Not only can serum kill bacteria, but most of the secretions of the
healthy human body are bacteria-killing as well. Gastric juice, Vaginal
secretion and nasal secretion, kill bacteria in enormous numbers. The hy-
gienic significance of this is evident from the fact that these bacteria-killing
substances. also, are moditied by modes of life. Dietary excesses may so
lower the bacteria-kiiling properties of gastric juice, and unsanitary condi-
tions so lessen that of the tissue juices that susceptibility to infectious dis-
eases is greatly increased.
The third way of hygienic in:portance in which the body fights disease,
is by phagocytosis. In the body there are millions of white blood cor-
puscles, each having the power of independent motion and as one of its
functions the faculty of eating and destroying disease germs.
It is found that the bacteria-eating power of white corpuscles is largely
dependent upon certain chemical substancesy present in the blood and
tissue juices. Without these chemical substances the eating of certain
pathogenic bacteria does not take place. With them, it is very active. It is
further found that these chemical substances are influenced by modes of
life. That they may be increased or decreased under different hygienic
conditions. Phagocytosis. therefore, has also a place in popular hygienic
knowledge.
One of the unfortunate results of the spread of knowledge of patho-
genic micro-organisms is the formation of an unreasoning popular fear of
disease germs. It is thought that a wide understanding of facts regarding
bodily resistance will tend to replace this unfortunate germ-fear by a
rational faith in the body’s marvelous powers. That it may turn the tide
of hygienic endeavor, from an exclusive fight against bacteria to a com-
bined fight wgdainst bacteria and for bodily resistance.

ConcERNING DIFFERENTIAL INVARIANTS.
Davin A. RovTHrRocK.
During the last forty years wonderful progress has been made in many
fields of higher mathematics. One distinct line of investigation has had to
do with a microscopic examination of the fundamental axioms of the ele-
mentary mathematics, of conditions of convergence, of the sufficient condi-
tions in the calculus of variations, and so on. Another essential advance
has been made by unifying many separate and apparently distinct fields of
mathematics under one common law. Among many adyances in this latter
line of work, none are more important than the work of Sophus Lie, a Nor-
wegian, who lived from 1842 to 1899.
Lie received his doctorate from the University of Christiania in 1865,
earing no more for mathematical work than for literary or philological
work. In fact, he had thought of becoming an engineer; but receiving an
appointment to a docentship in the university, he turned his attention to
the study of advanced mathematics. The real mathematical genius of
Lie was aroused by a course of lectures on substitutions by Professor Sy-
low. Lie’s creative period seems to have extended from 1868 to about 1874,
during which time he came into possession of the essential features of his
epoch-making Theory of Continuous Groups. The remainder of his life
was devoted to the elaboration of his early conceptions, and to the appli-
cations of his theories. A general development of the higher number sys-
tems, a classification of ordinary and partial differential equations, with
methods of their solutions, invariants and covariants, many problems of
physies and astronomy, are all treated from the standpoint of the con-
tinuous group. Below is sketched a brief outline of the continuous group
theory of Lie, as applied to differential invariants, and the calculation of an
important differential invariant is indicated.
1. Point Transformation. Let x, y be the Cartesian coérdinates of any
point in the plane, and let x1, yi be any point other than x, y. Then

86
is said to be a point transformation, carrying point x, y into point x, yi.
Here it is assumed that inversely
X= Da yA) Ye ay)
carries the point from x1, yi back to x, y. A point transformation may be
looked upon either as a transference of axes from one system to another,
not necessarlly the same kind of system, or it may be considered as an
actual transference of one point into another position in the plane, the
axes of reference remaining unchanged.
2. Group of Transformations. A point transformation containing one
or more parameters
9] =O (6S 5 Ey, D515, asa)
Nil 85 (OA VLE Al OG Op. on eal)
such that for ac, bo, Co,....Ko, the point x, y transforms into itself, is said
to constitute a group of transformations when a succession of two such
operations may be replaced by one of the same species. That is, if

are the transformations of an r-parameter group, the parameters a, b, c,
... kK being 7 in number and independent. A similar definition may be
given to a group in one, three, four, or n variables*.
3. The Infinitesimal Transformations. An infinitesimal transformation
is defined analytically by
Ox — & (xy) ot, Oy = 7) sy.) Ot:
Such a transformation attaches to any point x, y an infinitesimal motion
whose projections on the x —, and y — axes are respectively, cot and 7t,
and whose distance is )/ £272 dt. Lie shows such infinitesimal trans-
formations to belong to a single-parameter group.
x= OK ya) ny— LCi a)
This may be easily seen by letting a. be the value of a which leaves x, y
fixed; then

give to the point x, y an infinitesimal motion. Expanding in powers of da,
we have*

Omitting infinitesimals of higher order we have thie relations

as the infinitesimal transformations of a one-parameter group.
In the notation of Lie the symbol
ur=san(2jtren (XZ),
denoting the variation which a function / (x, y) undergoes when x, y
receive the increments 0 x, 0 y, is employed as the symbol of an infini-
tesimal transformation. Writing p, q instead of the partial derivative of
* (x, y) with respect to x and y, respectively, we have
U f= (x,y) P+ 7 (x, y) 4G.
The infinitesinal transformations of an r-parameter group would be given
by the symbol
Ux f = Sx (X,Y) p + 7 (3, y) g, K=—1, 2, 8,
4. The Group Criterion. One of Lie’s fundamental theorems furnishes
a test whether or not any given set of infinitesimal transformations, Ux f,
k=—1, 2, ... r, actually forms a group. This test is the application of
Jacobi's bracket expression
U; (Uj f)—Uj (Ui f), (i, j = 1, 2, .... 7, in all combinations).
*In this article the symbol (¢ +} will be used to denote the partial derivative of f with
regard to x, instead of the round d usually employed.
88
If the Jacobi bracket-expression, constructed for all combinations of
i, j, is equivalent to a linear function of the symbols Ux f with constant
coefficients, then are the symbols
Ux = &x (x, OAs ~~ m (X, Y) q, es L Pee r,
the infinitesimal transformations of an r-parameter group.*
5. The Extended Group. An infinitesimal transformation

may be extended in two ways. In the first place, the Taistion of the coor-

dinates of n points is simply the sum of the variations of the codérdi-
nates of the separate points; hence, U f extended in this manner becomes

Each of the members of an r-parameter group Ux/, k=1, 2, ... r, may
be extended, giving the infinitesimal transformations of the coordinates of
n points as indicated by equation (A); or each may be extended as in
(B) to include the variations of x, y ,y’, y’”, y’’”, -.. y™. A group of
transformations extended in style of (A) or (B) is called an extended group.

operated upon by an infinitesimal transformation.

ConsuGATE Functions AND CANONICAL TRANSFORMATIONS.

and that 0,, , each satisfy Laplace’s equation
by equating each to a third variable ¢ : ¢, (x, y) =, $2, (x, y) =¢. Hach
equation then represents a surface for any point of which Laplace’s equation
is true. By developing ¢ = ¢, (x, y) into a power series in the vicinity of
any point xo, yo, and using the Laplace equation, we have the theorem:
the projection of the section of a tangent plane to the surface ¢ = 9, (x, y)
upon the x, y-plane is a curve having a double point at Xo, yo with real,
orthogonal tangents, and hence the surface is hyperbolic at every point.
¢ =k gives lines of level on ¢ = 9, (x, y), while (=k, in¢=4@, (x,y)
gives cylinders which intersect ¢ = ¢, (x, y) in curves of quickest descent.

Nores on “Sautt Lime.”
FRANK B. WADE.
“Ye are the salt of the earth: but if the salt have lost his savour,
wherewith shall it be salted? it is thenceforth good for nothing but to be
‘ast out and trodden under foot of men.’—Matthew, vy, 13.
This passage from “the Sermon on the Mount” has doubtless puzzled
many a chemist, for salt without savour is as much an anomaly as a smile
(vithout a face.
Last summer, while spending my vacation at the seashore, I came
across an old-fashioned ‘salt works,’ where common salt is prepared by
evaporation of sea water, partly by means of trickling it over masses of
brush and further by solar evaporation in shallow vats.
It was while investigating the process that I came upon what seems
to me to be a plausible explanation of the scriptural passage, and at the
same time I secured a quantity of the material called by the salt makers
“salt lime,’ which is the subject of this paper.
It seems that the first solid product to separate from the sea water
upon concentration by evaporation is a very slightly soluble, white, crystal-
line substance, which gathers in the first four or five shallow vats. These
mre provided, so that the tasteless, gritty substance may not come down
along with the salt and constitute an undesirable impurity in it. This
tasteless substance is “salt lime.”
As to the connection between this substance and the salt which had
lost its savour, I think it very probable that the ancient salt makers omit-
ted to provide separate vats for the first, very slightly soluble product, and
that as a result it got mixed up with their salt. Then, possibly, owing to
exposure to moisture, the real salt may have become dissolved away from
this less soluble part in certain instances, and the residue, being tasteless,
would naturally be supposed to have “lost its savour,” by the unscientific
mind of that time.
Having secured eight or ten pounds of salt lime, I made an examina-
tion of the substance to determine its nature.
In physical appearance it is grayish white in color, crystalline in struc-
96
ture and it forms a layer about one-quarter inch thick as scraped from
the evaporators. I was told by the owner of the salt works that not over
thirty or forty bushels were obtained from the evaporation of an amount
of sea water that would yield 5,000 bushels of salt; so it will be seen that
the substance represents a high degree of concentration as the average per
cent. of common salt in sea water is only 2.61 per cent.* and the amount
of “salt lime’ obtained is only about 1 per cent. of that of the common
salt.
This high degree of concentration has led me to investigate the sub-
stance to see if it possesses any radio-activity, as, owing to the wide dis-
tribution of radio-active material more or less of it must find its way into
the ocean, and, judging from the position of radium in the periodic sys-
tem, the salts of radium ought to be found as sulphates among the less
soluble constituents of the ocean water.
Experiments are now under way with a view to still further concen-
trate the material and to find whether it contains any trace of radio-active
material.
Upon consulting the literature to which I have had access, I find that
mention is made in nearly all cases of the separation of gypsum (CaSQ,,
2H.0) prior to the separation of Common salt in the evaporation of both
sea water and natural brines from wells.
I have conducted a qualitative analysis of the salt lime in the regular
way and find that it does Consist mainly of gypsum. It has the water of
crystallization and gives the reactions of Ca and SO, It gives, moreover,
evidence of the presence of a small amount of carbonate of calcium. I have
seen no mention of this last fact in the literature to which I have had ac-
cess. In order to determine the proportion of carbonate in the mixture
I pulverized about 20¢. in an agate mortar until it had all passed through
a 100-mesh sieve; then taking a “fair sample,” as in assaying, I weighed out
5.6625 grams into a Schrotter apparatus and determined the weight of CO,
lost, in the usual manner.
The weight of CO. lost was .0156g, indicating a weight of .4854¢ of
CaCO, (calculated) or .62 per cent. CaCO,. A second determination gave
-71 per cent.
1 have tested carefully for Ba and Sr, using the ordinary form of
chemical spectroscepe as well as the regular analytical tests, and have

solid is salt.
97
found no trace of either. I have also tested for PO, and fluorine with nega-
tive results.
Pugin heating a sample of the salt Jime ina dry test tube, there was
a slight charring, possibly due to a slight amount of material from the
wooden vats or perhaps from sea algae. There was also a slight smell of
NH, on boiling a large mass of the finely-powdered substance with excess
of NaOH in an attempt to remove CaSO, to secure concentration of the
less soluble constituents. ‘This was probably also due to small amounts of
remains of sea algae..
From my study of the substance I would conclude that it consists
mainly of gypsum. but that it contains an appreciable amount of CaCO,
(.65 per cent.) and that it is remarkably free from other constituents, due
probably to the sharp distinctions in solubility between the less soluble and
the more soluble constituents of sea water. I hope to concentrate further
a considerable aniount of the substance and examine it for traces of radio-
active material or other constituents.

THe EFrect oF SuGAR ON SOURNESS.
P, N. EVANS.
It is common experience that some foods and beverages taste less sour
when sugar is added, and it seems worth while to seek an explanation of
the fact.
In books of popular science the statement is sometimes made that
the sugar “neutralizes” the acid—in some such way, presumably, as a base
might. This explanation is untenable from the chemist’s standpoint, in-
asmuch as sugar enters into no such reaction with acids.
Better informed writers sometimes ayer that since sugar can not neu-
tralize acids its value in such cases is only imaginary and not real. Since,
nowever, in matters of taste, if the imagination is satisfied the problem is
pracucally solved, it becomes of interest to know how the imagination is
satisfied in this instance.
Sourness is now known to be a property of the hydrogen ion; for all
acids, and acids only, are sour, and all have this constituent, and this only,
in common, when dissolved in water. A diminution in intensity of sour-
ness must therefore be due either to a reduction in the number of hydrogen
ions in a given volume of the solution, or to a lessened sensitiveness to
sourness on the part of the nerves of taste.
An investigation was made by the writer as to whether the introduction
of sugar diminished the degree of ionization of hydrochloric acid in a given
solution, using the freezing point method, and it was found that there was
no effect, the degree of ionization of the acid being the same in the pres-
ence and in the absence of sugar.
The value of sugar, then, must depend on its physiological effect on
the nerves of taste, not on any chemical action by which the concentration
of hydrogen ions is reduced.
Some years ago Professor T. W. Richards of Harvard University (Am.
Chem. Jour. 1898, 121), called attention to the delicacy of the sense of taste
in detecting sourness and in comparing it in different intensities. With the
assistance of Miss Carrie Richardson (now Mrs. C. E. Roth) the writer
99
made a series of over four hundred experiments in detecting acid in the
presence and in the absence of sugar.
The experiments were conducted as follows: Solutions of hydrochloric
acid of known strength were prepared, and equivalent solutions of sodium
hydroxide were added gradually, the solution being tasted after each ad-
dition until sourness disappeared. In other experiments the acid was
added to the alkali until sourness was noticeable. Both methods proved
about equally delicate. As long as the solution was strongly acid or alka-
line, ouly a drop or two was introduced into the mouth, but when the
neutral point was almost reached a cubic centimeter of liquid was used
and held in the mouth for a few seconds. The graduations of the burettes
were hidden during every titration, that the judgment might not be prej-
udiced.
Experiments were made with solutions of acid varying from 0.715
normal to 0.0143 normal, or solutions containing 0.715 to 0.0148 milligrams
of hydrogen ions per cubic centimeter. Sugar was added in quantities
ranging from 0.04 to 0.8 grams per cubic centimeter.
With the experience gained in about twenty titrations considerable
accuracy of taste had heen acquired, so that consistent results were then
obtained differing only about 1 part in 70 in a 15 cubic centimeter titration
with the stronger solutions and in the absence of sugar, from those ob-
tained with chemical indicators, the error being in almost all cases in the
same direction, as might be expected—sourness disappeared with the ad-
dition of less aikuli than the acidity as determined by phenolphthalein, or
sourness appeared only on adding slightly more acid than required by the
indicator. With the more dilute solutions, however, the absolute results
were more exact. This is accounted for by the presence at the end point
of less salt (due to the neutralized acid and alkali) in the more dilute solu-
tions, the presence of salt reducing the delicacy of the sense of taste for
sourness. With the most dilute solutions it was found possible to recog-
nize with certainty the presence of 0.U07 milligrams of hydrogen ions in
the mouth, in 1 cubic centimeter of liquid, although 4 milligrams of salt
were also present. In the most concentrated solution 0.01 milligrams of
hydrogen ions was recognizable in the presence of 34 milligrams of salt.
The presence of sugar had the same effect as that of salt—the more
sugar present in the solution the larger was the quantity of acid necessary
for detection by taste; even the largest quantities of sugar used (0.8 grams
per cubic centimeter) increased the necessary quantity of acid less than 1.5
100
times compared with that needed in the absence of sugar; 4.034 grams of
salt was about as effective as 0.8 graims of sugar. In other words, if the
mind is intent on noticing sourness, even large quantities of sugar do not
seriously interfere. In the usual eating of sweet and sour food, however,
the mind is, as it were, engrossed with the sensation of sweetness and ren-
dered correspondingly less sensitive to other tastes.
In al! probability any other powerful taste would be as effective in hid-
ing sourness as sweetness is, but no other taste in concentrated form is so
generally agreeable as sweetness. The sourness of lemonade would cer-
tainly be as thoroughly masked by highly salting it as by the addition of
sugar: the result would not, however, be as agreeable to the majority of
lemonade drinkers, probably.
In conclusion, brief reference might be made to a few experiments on
the effect of sugar on bitterness, as sweetness and bitterness are commonly
considered to be mutually exclusive terms—a thing can not be both sweet
and bitter, though it can be at once sweet and sour. The experiments were
made by the writer with mixtures of solutions of sugar and of quinine, but
it was found impossible to obtain any numerical results, for, no matter
what the proportion within very wide limits, the sensation of sweetness
preceded that of bitterness, the mixture tasting sweet at the first moment
and then bitter, the latter sensation being very lasting.
The use of sugar, then, to render sourness less intense, is based on a
physiological, not on any chemical effect; the nerves of taste are less sen-
sitive to one kind of taste in the presence of another, though the mind by
concentration can largely overcome this obscuring effect.

A Srvpite Metuop or Measurine Hyprotysis.
GrorGE A. ABBOTT.
Several methods of measuring the degree of hydrolysis of dissolved
salts have been proposed from time to time; e. g., the measurement of the
rate at which the solution saponifies an ester, such as ethyl acetate; the
rate of hydration of milk sugar; and the measurement of the partial pres-
sure of ammonia gas over solutions of its hydrolysed salts; but none of
these methods is precise, and even under the most favorable conditions,
they are far from satisfactory. The first is based upon the bold assump-
tion that the rate of saponification is proportional to the concentration of the
hydroxyl ions, and that it is nunaffeced by the presence of other molecular
aggregates; the second method involves a similar assumption; while the
last is of little if any practical value, owing to experimental difficulties.
The method about to be described was developed in the course of an
extended research on the dissociation relations of Ortho and Pyro Phos-
phorie Acids and their salts, which will be published in detail elsewhere.
It is simple and convenient, and should be capable of a fairly wide appli-
eation to the ammonium salts of other weak acids; therefore it has seemed
sufficiently interesting to justify a brief description at this time.
When an aqueous solution of ammonia is shaken up with chloroform,
the ammonia distributes itself between the two non-miscible solvents, and
the distribution ratio is constant at a given temperature. Fortunately this
ratio is of a magnitude which makes it possible to. determine the concen-
tration of the ammonia in the aqueous solution by simply titrating a meas-
ured volume of the chloroform with which the solution is in equilibrium.
It is obvious that we may take advantage of this fact to determine the con-
centration of the free ammonia in a solution of its hydrolysed salt, and thus
determine the degree of hydrolysis. It is free from assumptions and is as
direct as a chemical analysis itself.
But, simple in principle as the method appears, its successful applica-
tion requires attention to certain experimental details. The chief difficulty
arises from the fact that the ammoniacal solutions form emulsions with the
chloroform layer which remain turbid even after standing several hours in
102
the thermostat. Drops of the aqueous solution of variable size thus remain
suspended in the chloroform layer, making it impossible to obtain concord-
ant results when different samples are titrated. Fortunately this diffi-
culty may be easily overcome by merely rotating the solutions in glass-
stoppered bottles in the thermostat. For this purpose the bottles are fast-
ented to the axle of the rotary stirrer of the thermostat after the familiar
method of making solubility measurements, and allowed to rotate several]
hours (one to three), when the two phases invariably separate perfectly
clear, with a sharply defined bounding surface. In order to establish the
equilibrium between the solution of the hydrolysed salt and the chloroform,
the latter is vigorously shaken with the aqueous solution in a stoppered sep-
aratory funnel. The phases are allowed to separate, after which the water
layer is removed as completely as practicable, and another portion of the
solution is added. This process is repeated until three portions have been
shaken up with the chloroform; a fourth portion is then rotated with the
chloroform, at a constant temperature, as described above. It is important
to remove the sample of chloroform for titration without contamination by
any of the aqueous solution. This may be easily done by means of a
syphon. The short limb of the glass tube is sealed in the flame, and a
small thin bulb blown on the end. It may then be passed, closed, through
the aqueous layer, and opened by breaking against the bottom of the bottle.
The chloroform is syphoned into a clean, dry, vessel, measured, and titrated
with 0.02 Norinal hydrochloric, or nitric, acid, using methyl orange as in-
dicator. Enough pure water should be added to make a layer of convenient
depth to view the color of the indicator; since the latter does not enter the
chloroform, and the stoppered vessel should be vigorously shaken at in-
tervals during the titration.
The distribution coefficient of ammonia between chloroform and water
was measured, at 18°, at concentrations 0.1, 0.05, and 0.02 Normal, and the
mean of eight measurements gave 27.36. This is the ratio of the concen-
tration of the undissociated ammonia in the aqueous solution to the con-
centration of the ammonia in the chloroform.
The method was applied to the measurement of the degree of hy-
drolysis of Na.NH,PO,, at 18°, and concentrations 0.1, 0.05, and 0.02 molal,
with the following results:
103
Conc. Mols. per Litre. Per Cent. Hydrolysis.
0.1 95.39
0.05 95.44
0.02 95.65
That is, in a solution of Na,NH,PO,, at the above concentration, only
5 per cent. of the ammonia is chemically combined. When the hydrolysis
is large the method is accurate, and even v7hen it is small the results are
zood, as shown by the following values for the salt NaNH,HPO,:
Conc. Mols. per Litre. Per Cent. Hydrolysis.

These values are corrected for the ionization of the ammonia at the

Tue [onIzATION OF THE SuccEessIvVE HypROGENS OF ORTHO-
PHOSPHORIC ACID.
GEORGE A. ABBOTT.
The dissociation relations of polybasic acids are at present imperfectly
understood. Owing to the natural complexity of the compounds and the
experimental difficulties due to hyrolysis, hydration, and possibly asso-
ciation in solution. few investigators have attempted to determine the dis-
sociation constants of the different hydrogens of these acids; but the re-
cent development of physico-chemical methods of investigating the nature
of dissolved substances has made the solution of such problems appear en-
tirely practicable. Therefore an extended investigation was undertaken,
at the suggestion of Prof. A. A. Noyes, in the hope that an exhaustive study
of the dissociation relations of the phosphoric acids might contribute to-
ward a better understanding of their chemical behavior in inorganic re-
actions. ‘lhis investigation was conducted in the Research Laboratory of
Physical Chemistry of the Mass. Inst. of Technology.
In this paper I shail attempt to present briefly only a few results, in
the hope that they may prove sufficiently interesting to justify their presen-
tation. The method of measuring hydrolysis described in the previous pa-
per gives us at once a reliable means of determining the dissociation
constants of weak acids. ‘Vhen both acid and base are weak (slightly dis-
sociated), the following relation holds:
h2 Moers Kw
(d—h) Ky Ky
in which h# denotes the degree of hydrolysis of the salt, and Kw, Ka and
Ks are the dissociation constants of water, the acid and the base, respect-
ively. They are defined by the following expressions of the Mass Action
Law:
Kw = Cy & Con
Gy == (Chie CA
Cua
Ky = Cp x Con

Cou
105
The dissociation constants of the successive hydrogens of Orthophos-
phorie Acid will be designated K,. K. and K;. They are defined by the
Mass Action equations:
K, =H x 8H, PO,
H, Po,
Ke SH CaP OF
H, PO;
Ke POS
HPO;
They will be considered in inverse order.
Ks may be determined by substituting the value of h, obtained by the
partition method, in the hydrolysis equation.

K, = 6.48 x 10-'8 (mols. per litre).
Ks was also determined by an utterly independent method based upon
the measurement of the increase of electrical conductivity produced on
adding to solutions of Na.HPO,, varying amounts of ammonia. Time will
not permit a description of the method and calculations which are some-
what complicated, but the values obtained at different concentrations
agreed remarkably well with the above value.
In like manner Ix, may be calculated from the hydrolysis of NaNHy,
HPO, The value obtained by substitution in the above equation is K, =
3.9 x 10—", but this calculation fails to take into account the influence of
the unionized substances in the solution. :
The correction involves merely the application of the Mass Action Law,
and the principle that, in ab mixture of salts with a common ion each salt
has the same degree of ionization as if it were present alone at a concen-
tration equal to the sum of the concentration of the two salts. However,
the algebra involved is not particularly entertaining, and it will perhaps be
sufficient to give the mean corrected: value of K.—2.09 x 10—. It is then
seen that the correction is large. The value of K,, when corrected for the
influence of unionized substances becomes K.=5.55 x 10—".
The hydrolysis of the salt NH,H,PO, is too small to be measured by the
106
partition method, for the ionization of the first hydrogen of Orthophos-
phoric Acid is fairly large. It does not accurately obey the Mass Action
Law: hence K, has no defi-ite meaning. However, the degree of disso-
ciation was determined from the values of the electrical conductivity of the
acid and its salts, and other known data, and the following values were ob-
tained, at 18°C:
Cone. Mols. per Litre. Degree of Ionization.
0.1 0.286
0.05 .364
0.01 .602
0.002 .839
0.0002 .965
Ostwald’s Dilution Law requires that

wherein C represents the concentration and 7 the degree of ionization.
Substituting the values of * we obtain, for the values of K, at the different
concentrations :

and it is seen that the deviation from the law is marked.
A comparison of the ionization constants of phosphoric acid with those
of some other acids is interesting.

CoEFFICIENT OF EXPANSION OF Brick.
C. V. SEASTONE.
Inasmuch as brick is used extensively as a building material in differ-
ent ways and in different types of construction, and also beacuse it is used
to a large extent as a paving material, a knowledge of its physical proper-
ties is of value. With a view to increasing this knowledge a series of ex-
periments were made at Purdue University to determine the coefficient of
expansion of different grades of brick. It is the purpose of this paper to
give the results of these experiments.*
The method used to determine the coefficient was to subject a bar of
steel whose coefficient of expansion was known, and the specimen of brick,
to identical changes of temperature. The difference of expansion was
measured by the principal of the optical lever. This difference reduced to
unit length and unit temperature gave a correction to apply to the coef-
ficient of the metal bar.
The apparatus used for these experiments was designed by Professor
W. D. Pence, former Professor of Civil Engineering at Purdue University,
and used by him to determine the coefficient of expansion of concrete. It
consists of, first, the specimen to be tested; second, the bar of steel of
known coeflicient; third, a heating apparatus, consisting of a double-walled
steam jacket through which the mirror of the optical lever could be seen;
fourth, a rod in the opposite side of the room, whose image, reflected in the
mirror, was read by means of an engineer’s level. The thermometer is
hung inside the heater and is read through the glass door by the aid of an
incandescent lamp suspended alongside of it. The lamp is turned on only
for an instant in order not to affect the reading of the thermometer. Both
the level and the steam jacket were mounted upon a concrete foundation.
The arrangement of the apparatus and the method of conducting the ex-
periment will be easily understood from the figure.
*The experiments were conducted, under the writer’s direction, by W. J. Burton and
C. W. Wilson (1902-1903), and by G. W. Case and G. C. Curtiss (1904-1905), as thesis work in
the School of Civil Engineering, Purdue University.
109
Three qualities of brick were used. First, a good quality of No. 1
paving brick; second, a medium quality of No. 2 paving brick; third, a
soft quality of ordinary building brick. The brick were approximately
2”x4"x8” in dimension and were cemented together in order to obtain the
specimen of desired length.
Following is the mean yalue obtained for each of the above qualities of
brick:
No. 1 brick (hard) Coefficient of Expansion per degree F — .00000401.
No. 2 brick (medium), Coefficient of Expansion per degree F =
-00000401.
No. 3 brick (soft), Coefficient of Expansion per degree F — .00000393.
It will be noted that the hardness of the brick has little to do with the
amount of expansion, the three qualities giving essentially the same values.

CONTRIBUTIONS TO THE KNOWLEDGE OF VEHICLE Woops.
W. K. Harr.
It is admitted by both the forester and the manufacturer of vehicley
that the supplies of hickory and like woods used in vehicle construction are
becoming scarce. The quality is poorer and the price is higher each suc-
ceeding year. Indeed, the condition with respect to the supply of vehicle
woods may be said to have become acute, and the various trade organiza-
tions have become aroused to such an extent that meetings have been held
to discuss means of increasing the sources of supply and economizing on the
construction.
Three ways in general are open:
First, an endeavor may be made to determine the availability of new
species as substitutes for such woods as hickory and white oak.
Second, planting operations might be made.a success.
Third, a more economical use may be made of the timber supplies now
entering the mills for manufacture into wagon parts.
The present paper discusses lines of effort in the substitution of new
and untried species, and in improving rules of grading in the mills so that
excellent material, fully available for service, may not be thrown out, as is
the case now, by incorrect rules of grading.
The Forest Service, United States: Department of Agriculture, and the
Purdue University Laboratory have for some years co-operated in the es-
tablishmnent of a timber testing station in the Laboratory for Testing Ma-
terials of Purdue University, at which studies have been made to determine
the essential mechanical properties of various species of wood, and what
effect various factors have upon these properties. Other studies to deter-
mine the correctness of the rules of grading for vehicle parts, and to ex-
amine into the merits of different designs of such parts as wagon axles,
and to investigate the properties of possible substitutes, have a direct ap-
plication to an important industry of the State. This Laboratory at Pur-
due University is one cf a series of laboratories operated by the Forest
111
Service at such institutions as the Yale lorest School, and the Universities
of California, Oregon and Washingten. ‘The writer of this paper has been
in charge of this work since is inception in the year 1903.
SUBSTITUTION OF NEW SPECIES.
The practice of substituting cheaper and weaker species for others
which have become scarce and high priced has been increasing for some
time. For instance, longleaf pine harvester poles have come into use in
place of oak poles, and those parts of vehicles not bearing a great strain
are now made of weaker woods. ‘She successful introduction of species
which are quite proper for the service is generally retarded by prejudice.
Consumers have demanded certain species regardless of their actual fitness,
and irrespective of the fact that ether and cheaper woods might answer the
purpose equally well. Tor instance. both poplar and red gum, which are
now held in such high estimation, have both had to fight their way for a
place on the market for such parts as wagon box boards.
It may be stated at the outset that there is probably none of our east-
ern species that can replace hickory for strength and general shock-resist-
ing properties and permanence of shape after it is bent. The lines of en-
deayor must be to use hickory in only such parts of the wagon where great
shock-resisting properties are required, and to correct the rules of grading
so that minor defects which do not affect the strength of the wagon are not
allowed to operate to throw a suitable piece of hickory out of use. A re-
cent study of the properties of the eucalypts in California by the Forest
Service seems to point to the value of some of these species for use in
wagon construction. The blue gum (Eucalyptus globulus) is the most com-
mon species in California, and has competed with black locust for insulator
pins, and has given satisfactory service in chisel and hammer handles, and
has been used locally for wagon tongues, axles. shafts, spokes, hubs and
felloes in California. The wood is hard, strong and tough, and grows very
fast. In bending the modulus of rupture is 23,000 pounds per square inch
for seasoned lumber, about equivalent to second-growth hickory. This
eucalypts seems to be the most promising species upon which to draw for
products requiring great strength. toughness and hardness.
GRADING RULES.
An instance of the method of attack to determine the correctness of
the grading is in the case of hickory wagon spokes, which are now graded
Jed
into six divisions: A, B, C, D, @ and Culls. Five hundred spokes were
procured from the Bannister Wheel Company of Muncie, Ind., and were
tested under a direct load as shown in the diagram, and the maximum load,
together with the amount of bending sidewise before fracture was noted.
This combination of maximum Joad and amount of side bending gives a
factor which represents toughness and shock-resisting capacity. The re-
sults, from the spoke tests show more than 50 per cent. error in the present
grading system, which is largely due to the traditional prejudice and con-
sequent discrimination against red hickory. No red spokes are now al-
lowed in the A and B grades, yet these tests show that a large proportion
of the red spokes now included in the lower grades should be, because of
their strength and toughness, included in the highest grades. It appears,
also, that weight for weight. the red spokes and the mixed red and white
spokes, are fuliy as strong as the entirely white spokes. These tests will
be supplemented by tests on various hickory buggy shafts containing typical
defecis. Such tests have an interest not only to the genral public, in that
a drain on a limited class of material is somewhat decreased, but they have
an interest also to the grower of tiniber, because they increase the market
value of a cousiderable portion of the product of the forests.
Tests have also been made on a number of wagon axles. Various
species of woods, not only from the western forests, but from eastern
forests. have been made up into axles at a mill and have been submitted
to the laboratory for test. At the present time the series is complete upon
hickory and maple axles of three different designs, and the method of at-
tacking the problem and of determining the qualities of the axles by actual
test will be of interest from a scientific standpoint. (Referring to the
photograph of an axle under test, the method of loading and measuring
and the behavior of the axle is shown in detail, and the various quantities
entering into an estimation of the value of the axle are explained.)
Another example is in a series of tests to determine the proper grad-
ing of pine harvester poles. . .2 2 nce actin pete: Ae OOS cexeeres aOeee Bloomington

LUCIEN MARCUS UNDERWOOD.
A BIOGRAPHIOAL SKETCH.
Lucien M. Underwood was born October 26, 1853, in New Woodstock,
New York, and died at his home in Redding, Connecticut, November 16,
1907. At the age of fifteen he entered Cazenovia Seminary, where he pre-
pared for college. In the fall of 1873 he entered Syracuse University.
graduating from this institution in 1877. His career as a seminary and as
a college student was marked by unusual scholarship. In the college cur-
riculum his favorite studies were history. mathematics and geology. Dur-
ing this period he began the collection of an herbarium, and, self instructed,
undertook the study of the ferns. He also gave much attention to ento-
mology.
At the time of his graduation he decided to enter the profession of
teaching and for several years his work was in small institutions where
he was compelled to instruct in a wide range of subjects. In 1878 he took
his master’s degree at Syracuse University, having completed a year’s
graduate work in addition to performing the arduous duties incident to
the principalship of a school where he was obliged to conduct fourteen
classes a day. In 1878 and 1879 he taught natural science in Cazenovia
Seminary. In July of 1878 he published his first botanical paper, a list of
ferns occurring about Syracuse, N. Y. From this time on his inclination
to specialize in botany grew. but it was not until 1880, when he became
professor of geology and botany at the Illinois Wesleyan University at
Bloomington, that he had opportunity to do much botanical work.
In 1881, while at Bloomington, he published his manuscripts on ferns
under the title “Our Native I‘erns and How to Study Them.” This publica-
tion met with great success, the sixth edition appearing in 1900. In 1883
he was called to Syracuse University as instructor in geology, zoology and
botany and three years later was made professor—remaining in this posi-
tion until 1880 when he secured a year’s leave of absence to study the
collections of hepatics in Harvard University. While in Cambridge, Mass.,
he accepted a professorship of botany at DePauw University. This posi-
tion was the first which enabled him to devote his time to botany alone.
For four years, until 1895, he enjoyed at DePauw University a period of
20
work under congenial surroundings. publishing numerous papers on the
lower groups of plants. In 1895 he left DePauw to accept the professor-
ship of biology in the Alabama Polytechnic Institute at Auburn. After one
year at Auburn he became professor of botany in Columbia University in
July, 1896, and continued in this position the remainder of his life.
Dr. Underwood was a member of the original committee on nomencla-
ture at the Rochester meeting of the American Association in 1892 and was
selected as the delegate to carry the report of the American botanists on
this question to the International Botanical Congress in Genoa. He was
one of the vice-presidents of the Genoa Congress. He was vice-president
of the Botanical Section of the American Association at the New York
meeting in 1894.
At Columbia University his career was one of great honor. He was
one of the ten botanists elected at the Madison meeting of the American
Association for the Advancement of Science to form the Botanical Society
of America, and served as president of this organization, 1899 to 1900.
From 1898 to the end of 1902 he was editor of the publications of the Tor-
rey Gotanical Club. He was associate editor of the North American Flora.
He was a member of the Board of Scientific Directors of the New York
Botanical Garden, serving as chairman since 1901. Syracuse University
in 1906 conferred upon him the degree of Doctor of Laws in recognition
of his long and distinguished scientific service. Dr. Underwood’s published
botanical papers and texts number i198 titles. In addition he was the
author of other papers on zoology, geology, geneology and miscellaneous
subjects. (See article on the published works of L. M. Underwood by
John Hendiey Barnhart, Bulletin Torrey Botanical Club, page 17, January,
1908.)
Dr. Underwood was a man of cheerful, genial disposition, sympathetic
and helpful. He was especially kind to students and to young men in his
profession and all who came in contact with him were impressed with
his generosity and sincerity. He had rare power in making and keeping
friends and none who has had the good fortune to enjoy his acquaintance
will forget the charm of his delightful personality.
In 1881 Dr. Underwood was married to Miss Marie A. Spurr. By this
union there was one daughter Miss Helen Willoughby Underwood. Dr.
Underwood is survived by both wife and daughter.
During his residence in Indiana Dr. Underwood took a lively inter-
est in the Indiana Academy of Science, contributing many valuable papers
26
representing a large amount of research work preparatory to a biological
survey of the State. His work for the Academy was not confined to the
contribution of scientific papers, but included faithful service on comumit-
tees and aid in promoting the business interests of the organization.
Furthermore his concern for the Academy was maintained throughout his
life and after remova! from the State Dr. Underwood was ever solicitous
for the welfare of the Indiana Academy of Science. In the untimely death
of Dr. Underwood the members of the Academy have lost a valued co-
worker in science and a true and warm hearted friend whose memory will
always be held in most tender regard.

Tue History anp ConTrROL oF SEx.

The student of sex and closely related problems of heredity may ra-
tionally ask himself any or all of the following questions: What is the
significance of sex? or, in other words, why are organisms male and female?
Is the sex of the organism determined during the early development of the
individual? or is it predetermined in the germ cells? If the former, what
conditions of the environment are favorable to the development of males
and what to females? If the latter, what is it in the gametes or sex-cells
that predetermines maleness or feinaleness?
As in the establishment of the doctrine of sexuality itself, these ques-
tions can be answered by experiment only and by the microscopic investiga-
tion of the germ cells and the manner of their development. As an intro-
duction to what [ shall have to say in this paper concerning sex control, I
desire to point out briefly those lines of study which seem to me to have
been most effective in establishing the doctrine of sexuality in plants; for
it will be seen that the lines of investigation which established the theory
of sex are similar to those that are yielding the most fruitful results in
the study of the more difficult hereditary problems of the present day.
When in the history of civilized or semi-civilized man, the idea arose
that plants possess sex, no one can tell or perhaps imagine. Before the
days of written history the old Arabs of the desert knew that certain palm
trees produced fruit, while others did not, and, in order that the fruit
might develop abundantly. it was necessary to bring the flowers of the
sterile trees and hang them upon the branches of those which bore the
fruit. It is evident that they also practiced the caprification of the fig,
using the same methods employed at the present time in the fig-growing
localities along the Mediterranean, for we read in Herodotus who, in speak-
ing of the Babylonians, states that, ‘““The natives tie the fruit of the male
palms, as they are called by the Greeks, to the branches of the date-bearing
palm, to let the gall-fly enter the dates and ripen them, and to prevent the
fruit falling off. The male palins. like the wild fig trees, have usually the
f
29
gall-fly in their fruit.’ Wlerodotus was in error in regard to the presence
of the gall fly in the palm, and it is said that Theophrastus was the first
to point out the inaccuracy in the statement. This brilliant and gifted
pupil of Aristotle was probably the foremost of all ancient botanists, for,
it is said, he knew six hundred plants. The ideas of Theophrastus upon
this subject seemed to be more definite than those of his great teacher. He
regards the palm and terebinths as being some male and some female, for
“it is certain,” he says, “that among plants of the same species some produce
flowers and some do not; male palms, for instance, bear flowers, the female
only fruit.” Let it be borne in mind here that neither Theophrastus nor
the botanists of the 16th and 17th centuries considered the rudiment of
the fruit to be a part of the flower. Theophrastus probably added very
little to the knowledge of sexuality in plants which had been handed down
to him either in the form of tradition or through the scanty writings
upon natural history. 'That he seemed to have made no observations upon
the subject, but te have relied in a large measure upon heresay, is ap-
parent from the following: ‘‘What men say that the fruit of the female
date-palm does not perfect itself unless the blossom of the male with its
dust is shaken over it, is indeed wonderful. but it resembles the caprification
of the fig, and it might almost be concluded that the female plant is not
by itself sufficient for the perfecting of the foetus.” In the time of Pliny,
this idea of sexual difference in plants had been pretty well confirmed in
the minds of educated men. Jn his ‘Historia Mundi,” in describing the re-
lation between the male and female date-palm, Pliny calls the pollen-dust
the material of fertilization, and says that naturalists tell us that all trees
and even herbs have the two sexes.
Now while the ancients had seme notion of sex in plants, their ideas
were based chiefly upon certain apparent analogies with animals. It must
be borne in mind that whilst the ancients attributed to the pollen the power
of fertilization, they had no notion that this fertilization was anything
further than some unexplained subtile influence of the flower dust upon
the fruit. However, we should wonder only at how much they knew in
the days of Herodotus and Theophrastus as compared with the progress
of knowledge made along this line during the following two thousand
years: for the time from Aristotle to the discovery of the cell by Robert
Hooke, the publication of the great: works on anatomy by Malpighi and
Grew, and the experiments of Camerarius in the latter part of the 17th
century, was a lapse of long and dreary centuries in the history of science.
30
This was not because there were no men willing to devote their time to
natural history, but chiefly because of the attitude of mind which de-
manded that problems arising be not solved by observation and experi-
ment, but by the process of deductions from the authorities. The ques-
tion was not, what do the observed facts teach? but, how are they to be
interpreted from what Aristotle says?
The improvement of the microscope and the extensive studies on the
minute anatomy of piants did not bring the results that might have been
reasonably expected. In spite of his excellent work on the anatomy of
plants, Grew seemed to have been unable to gain any true insight into the
structure and function of pollen. He did not even consider the stamens as
the so-called male members of the Hower, speaking of them only as the
attire, but he records a conversation with an otherwise unknown botanist,
Sir Thomas Millingten, who was probably the first person to claim for the
stamens the character of male organs. I quote from the “Anatomy of
Plants” (chap. V, secs. 3 and 4, page 171): “In discourse hereof with our
learned Savilian professor, Sir Thomas Millington, he told me he conceived
that the attire doth serve as the male for the generation of the seed. I
immediately replied that i was of the same opinion and gave him some rea-
sons for it and answered some objections which might oppose them.” But
how badly Grew must bave been confused in the matter may be seen from
his description of the florets in the head of certain Composite. He re-
garded the style and stigma of the floral attire as a portion of the male
organ, Speaking of the small globulets (pollen grains) in the thecae (an-
thers) of the seedlike attire as a vegetable sperm which falls upon the seed
case and so “touches it with a prolific virtue.” Grew could conceive of sex
in plants only in the form of certain apparent analogies with animals. He
reasoned that the same plant may be both male and female, because snails
and some cther animals are so constituted, but to complete the similarity
between the plant and the animal would require that the plant should not
only resemble the animal, but should actually be one. Down to the year
1691, about all that was known concerning the sexuality in plants was com-
prised in the facts related by Theophrastus for the date-palm and the tere-
binth, and in the conjectures of Millington, Grew and others, while Mal-
pighi’s views in opposition to these authors were considered equally well
founded.
The doctrine of sexuality in plants could only be raised to the rank
of scientific fact by experiment. It was necessary to show that no seed
D1
capable of germination could be formed without the aid of pollen, and all
historic records concur in proving that Rudolph Jacob Camerarius was the
first to attempt to solve the problem in this way. Dioecious plants were
cultivated apart from each other, but no perfect seeds were formed. He
removed the stamens from the fiowers of the castor oil plant and the
stigmas from maize, with the result that no seeds were set in the castor
oil plant, and in the place of grains of corn only empty husks were to be
seen. The results of Camerarius were published in 1691-94. At this time
the authority of the ancients was So great that Camerarius thought it neces-
sary to insist that the views of Aristotle and Theophrastus were not op-
posed to the sexual theory. Among the few experiments carried out in the
next fifty years were those of the Governor of Pennsylvania, James Logan.
an Irishman by birth. Logan experimented with some plants of maize.
Upon a cob from which he removed some of the stigmas, or silks, he found
as many grains as there were stigmas remaining. One cob which was
wrapped in muslin before the silks appeared, produced no kernels. In 1751,
Gleditsch, director of the botanic garden in Berlin, had been told that a
date palm eighty years old, which had been brought from Africa, never
bore fruit. As there was no staminate tree of the species in Berlin, Gled-
itsch ordered pollen sent from Leipzig. The journey required nine days,
and although Gleditsch thought the pollen spoiled, the male inflorescence
was hung upon the Berlin tree, with the result that seeds were set which
germinated in the following spring.
The century following the discovery of Camerarius was characterized
by two lines of investigation which, wore than any other activity of bot-
anists, led to the complete establishment of the sexual theory. I refer to
the refutation of tbe old theory of evolution together with the birth of the
doctrine of epigenesis, and the discovery of hybridization; the first of these
being the outcome of microscopic studies, and the latter that of experimen-
tation. It may be said in this connection that the history of biological
science teaches that the greatest and the most substantial progress has
been made where the studies of the morphologist and of the experimenter
have gone on side by side, the one serving as a control upon the other.
According to the old theory of evolution, or the inclusion theory, that the
germ in every seed, for example, contained all the parts of the organism,
and that this germ enclosed a similar one in miniature, and so on, like a
box within a box. This view of the inclusion of germ within germ was
very prevalent in the 18th century, and Kaspar Friedrich Wolf (1759) has
32
been given the credit of refuting it. Wolf, in his doctor’s thesis on the
“Theory of Generation,” maintained that the embryo and organs of a plant
develop not by the unfolding of parts already present in miniature, but
that they grew out of undifferentiated rudiments, the theory of epigenesis.
However, Wolf’s argaments were far from convincing, as he held that the
act of fertilization was merely another form of nutrition.
About the same time experiments in hybridization were being carried
on by several investigators, and the results obtained supplied much more
convincing proof against the old theory of evolution. Among the fore-
most men in this held were Gottlieb Koelreuter and Christian Konrad
Sprengel. While Wkolreuter brought together many important observations
on the sexuality of plants, yet his greatest service consisted in the produc-
tion of hybrids. In this connection it may be of interest to note that his
first hybrids were produced between two species of tobacco plants. Nico-
tiana panicum and N. rustica. What he accomplished did not require be-
ing changed, but when combined with later observations has been used in
the discovery of general principles of hybridization. His work seems to
belong to our time. Koelreuter showed that only closely allied plants, and
not always these, were capable of producing hybrids, and that the mingling
of parentai characters in the hybrid was the best refutation of the theory
of evolution. It was no easy matter to place the proper estimate upon the
value of the contributions of this gifted observer. The collectors of the
Linnaean school, as well as the true systematists at the close of the 18th
century. who wielded a powerful influence upon botanical thought, had lit-
tle understanding for such labors as Ioelreuter’s, and incorreet ideas of
hybrids prevailed in spite of botanical literature. Hybrids were also incon-
venient for the believers in the constancy of species.
Koelreuter’s studies were not confined to hybridization alone, for he di-
rects attention to the natural way of the transfer of pollen from stamen
to stigma, being tiie first to recognize the agency of insects. He studied
pollen grains, showing that fertilization followed pollenation in the ab-
sence of light. and rejected the idea that the pollen grain passed bodily
into the ovary. With the microscope, however, he was less skillful than
as an experimenter, for he supposed the pollen grain to be solid tissue, and
the fertilizing substance to be oil which adheres to the outside of the grain
and tinds its way to the ovule. The pollen tube had not been discovered,
although the time was one hundred years after the discovery of the cell
by Robert Hooke.
33
As Camerarius first proved the sexuality of plants, and Koelreuter
showed that different species can unite sexually to produce hybrids, so
Sprengel demonstrated that a certain kind of hybridization was very com-
mon in the vegetable kingdom, namely the crossing of flowers of different
individuals of the same species. To him belongs the credit for having first
shown the part played by insects in cross pollenation, and pointing out the
correlation between such properties of the flower as color, odor, nectar,
special forms and markings, and so forth, and the visiting insects.
Karl Friederick Gaertner, son of Joseph Gaertner, took up the work so
ably begun by Koelreuter, and greatly extended the knowledge of hybridi-
zation, having kept accurate account of nine thousand experiments. His
work was published in 1849. Sachs states that ‘These observations once
more confirmed the existence of the sexuality in plants, and in such a
manner that it could never again be disputed. When facts were observed
in 1860, which led to the presumption that under certain circumstances in
certain individuals of some species of plants, the female organs might pro-
duce embryos capable of development without the help of the male, there
was no thought of using these cases of supposed parthenogenesis to dis-
prove the existence of sexuality as the general rule; men were concerned
only to verify first of all the occurrence of the phenomena, and then to
see how they were to be reasonably understood side by side with the ex-
isting ideas ot sexuality.” Gaertner’s experiments were conducted at
Claw, in Wurtemberg, the place in which Koelreuter carried on his studies ;
Camerarius worked in Tiibingen.
While the experimenters in hybridization were at work, the student
with the microscope was no less busy. In 1823, Amici discovered the pollen
tube in the stigma, and the fact was confirmed by others. In 18380, the
same observer traced the pollen tube into the ovule. Schleiden and
Schacht now caine forward with their erroneous theory of the formation
of the embyro in the seed. ‘They maintained that the embyro develops
from the end of the pollen tube after the latter enters the ovule. It is
clear that this doctrine would do away with the essential point in the
sexuality of plants, for the ovule would be regarded merely as an incu-
bator for the embyro. Amici, in 1846, brought forth decisive proof for the
view he had maintained. namely, that the embryo arises not from the end
of the pollen tube, but from a portion of the ovule which already existed
before fertilization, and that this part is fertilized by a fluid contained in
[8—18192]
o4
the pollen tube. ‘The correctness of this view was confirmed the following
year by von Moil and Hotineister, the latter of whom described the points
in detail which decided the question, and illustrated them with beautiful
figures.
Following the publication of Amici, a vehement controversy arose be-
tween the adherents of the views of Schleiden and those of Amici. i iS) < a n

The value of any fuel depends upon the quantity of heat generated and
the temperature which can be obtained. The influence of moisture and
ash upon the heating power of peat is well shown in the following table*:

It will be noticed that the difference between two samples of peat
having a different content of moisture is greater than that due merely to
the displacement of combustible matter. ‘The loss represents the amount of
heat consumed in vaporizing the moisture. This demonstrates the neces-
sity of preparing peat for use as fuel so as to contain the least possible
amount of moisture.
A comparison of the heating power of peat and various other fuels is
given in the following tables? :

It gives results always in favor of the contractor and on very short

Method No. ®% depends upon the general proposition that the position
of half mass point is approximately the position of the center of mass
and graphically looks like figure below.
Haul equals the mean length of the two sides of the given tropezoid
and the pay haul equals the aera of the tropezoid. This method gives re-
sults always in favor of the contractor and on very short hauls is rarely
in error to exceed say 4.0 per cent., and on long hauls rarely in error to
exceed say 6.0 per cent.

the product of the two being also the area of the mass diagram.
If the points are connected by a curved line it will give practically
the true result. but if the points of the diagram are connected by straight
lines as is recommended by most engineers, and aS was done here, it gives
values always against the contractor; on short haul being in error as
high as 6 per cent., and on long haul about 1.0 per cent.

Fauna OF THE FLORENA SHALE OF THE GRAND Summit SEc-
TION OF Kansas, AND REMARKS ON THE DEVELOP-
MENT OF DerRBYA MuuLtistrIATA MEEK AND HaybDEN.
EF. C. GREENE.
The Grand Summit section of Cowley county, Kansas, has been fa-
mous as one of the Classic collecting grounds of Kansas and many large
collections have been made there. It could probably be classed as Permo-
Carboniferous, very near the base of the Permian. The region was first
studied by Broadhead in 1882 and the account published in 1888 or 1884.
He says, “We now come to speak of the ‘Permian’ or limestones of the
‘Flint Hills, reaching, in Elk, Greenwood and the eastern half of Butler
and Cowley counties. from 1185 to 1700 feet above the sea, including about
500 feet thickness.’’*
Only the top part of broadhead’s section concerns us. Numbering from
top down, it is as follows :7
. 1. 134 feet, including beds of impure drab limestone, shaly and
crumbling, with occasional shale beds. with red shales 30 feet from bot-
tom.
2. d feet of bluish-drab or drab limestone containing many good char-
acteristic fossils, including Eumicrotis hawni, Myalina perattenuata, Avi-
culopecten occidentalis, etc. (This bed is persistent wherever its associated
strata are found.)
3. 10 feet of shales, the lower red.
4. 10 feet of rough limestone.
5. 27 feet of shales with thin shaly limestone beds.
6. 4 feet of flag-like limestone; a good building stone.
7. § feet of shelly buff magnesian limestone.
Ss. 4 feet of shaly Fusulina limestone.
9. 4 feet of cherty limestone; abound in Fusulina cylindrica, the
fossils often appearing in relief: the chert of deep blue. sg

10. 18 feet limestone and shales abounding in Fusulina cylindrica.
11. 2 feet drab magnesian limestone.
12. 28 feet shaly sandstone.
He considered all above number twelve of this section as Permian
which would make the base of the Permian about the horizon of the Em-
poria limestone of the recent geologists.
“Mr. George I. Adams has also described in a somewhat general way
the section along the line of railway through Moline, Grenola, Cambridge,
and Winfield.” |!
In 1896 Prof. Prosser hastily examined this section. He determined
number 27 of this section to be the lower part of the Strong limestone.
The Strong or Wreford is now supposed to be the base of the Permian.
In the field season of 1904 Prof. Beede made a detailed section at
Grand Summit as follows :§

Since the u-curves are plane and have constant radi of curvature they
are circles.
Finally, the plane of each v-curve is normal to every u-circle, and
therefore passes through its center. The intersection of any two v-planes
determines the line of centers of the u-circles. Thus all the required sur-
faces are surfaces of revolution. Taking the line of centers of u-circles as
z-axis and the plane of any u-circle as xy-plane, the equation of our sur-
faces are

LINES ON THE PSEUDOSPHERE AND THE SYNTRACTRIX OF ReEv-
OLUTION.
EK. L. HANcock.
INTRODUCTION.
Consider two surfaces of revolution S and Si generated by the revolu-
tion of the curves C and C; about the Z axis. Ci is formed by taking on
the tangents to C distances equal to the constant-k’ times the length of the
tangents. The length in each case is measured from the z-intercept toward
the point of tangency. Let C = O be given by z=f(u), then Ci = Owill
be given by,
a = (L — 1)umif’(Lu1) + f(Lm)
where L = 1/k’ and the equations of transformation from § to Si are,
Gg oy
vV— Vil
When the length of the tangent to the curve C is constant, as in the
tractrix, the curve Ci is the syntractrix (see Note), and the surfaces S and Si
are therefore the pseudosphere and the syntractrix of revolution.
What follows is the study of lines on these surfaces. The geodesic
lines on the pseudosphere have been studied by means of lines in the plane,
This surface being one of constant negative curvature (—l) may, accord-
ing to Beltrami (see Note 2), be represented geodesically by a system of
straight lines in the plane.
Much of the work outlined here for geodesics’on the pseudosphere may be
found in Darboux, Theorie des Surfaces, Vol. III, and is given here only in
the way of review and for completeness.
The claim made for the originality in this part of the work is in (1)
the classification of the geodesic lines and the study of certain systems of
geodesic lines and their corresponding lines in the plane; (2) the transforma-
tions of the system of circles into straight lines by making use of the sphere,

as indicated; (3) the study of the asymptotic lines and the loxodromic lines
on the pseudosphere and their representations in the plane.
In the second part of the work the lines on the syntractrix of revolu-
tion are studied. This work so far as I know has never been done before
In it I have worked out the equations of the geodesic, asymptotic and loxo-
dromic lines. These have been studied in particular by classifying the
surfaces Si according as d = 2C, where © is the length of the tangent to
the tractrix and d the constant distance taken on that tangent. When
d = 2C it happens that the geodesic lines on §: are all real and that the

of straight lines as the loxodromic lines of the pseudosphere. The draw-
ings are given for the sake of clearness.
CHAPTER I.
GEODESIC LINES ON THE PSEUDOSPHERE.
Taking the equation of the tractrix in the form,
x = C cosh.'c y — (C2 — y?)!/? we get for the given surface,
K == COB eo ee, en eee Oe oe (2)
¥ = UW sinty
z == C. cosh.—c/u — (C? — u?)!/?
and the fundamental quantities of the Gaussian (see Note 1) notation are,
BE = C?2/u?, F = 0, G= v2, D = (C?)/(u(C? — u2(7/?), D’ = 0,7
p= —a (C2 — ae)? Ke
Using the method of calculus of variations as developed by Weier-
struss (see Note 2) to obtain the equations of the geodesic lines, we have
to minimize the integral,

=. ft 272 2) | 7 2\1/2 ate

Legendre’s condition for a minimum is Fy — (d/dv )Fv’ = 0 where
(Fv) = (6F)/(év) and Fv’ = (6F)/(d6v’).
Here Fy — 0, so that we get as the equations of the geodesics
Fy’ = (a2v’)/((C7a2/02) + n?v’2)1/2? =a (3)
Where « is the constant of integration.
Note i.—Bianchi, Differential-Geometrie, pp. 61 and 87.
Note 2.—Kneser, Variationsrechnung.
Osgood, Annals of Mathematics, Vol. 2, p. 105.
143
In considering these curves two cases may arise, (1) when « —0,
(2) « +0. Case (1) when x =—0, either u=—Oorv=0. But u+0
hence v’ = 0.and so v — constant. That is the meridians are geodesics.
Case (2) when x + 0, (3) becomes
Ves (Conn): (teen (4/2 Be) BE Eu (4)
This may, however, be put in a more convenient form, since in the present
case the geodesic lines vy = constant all meet in a point and the curves
u constant form a system of geodesic circles — the orthogonal trajec-
tories of the meridians. Under such conditions E may be equated to unity
(see Note 1). The new uz is then given by the relation us = { (E)2/? du.
Hence u = e”?/c, Replacing in (4) u by its value just found the equation
of the geodesic lines becomes
v= (C/a )(l — a 2e—4/c)1/24 B (see Note 2)...... (5)
This equation may be used to determine the allowable values of «
and 6. The constant 6 being additive has no effect except to turn the sur-
face about the z axis. Thus a geodesic line given by one value of 8 may
be made to coincide with one given by another value of { by revolution
about the z axis, x remaining constant. $ may vary from —o to4+ om.
From (5) it is seen that the lines are real or imaginary according as

By (9) the x axis goes into the parabola x? = y and all the lines y = con-
stant go into the parabolas x? —y + constant. The whole upper part of
the plane is represented inside the parabola x?—y. The points on the
lines x = constant are moved along the lines. The origin is the fixed point
of transformation.
Circles concentric at the origin correspond to lines y — constant while
every system of concentric circles on the x axis goes over into a system of
parallel lines. A system of circles given by (8) passing through a point
corresponds to a system of lines through a point. A system of circles with
the y axis as radical axis
x?+ y?— 26x + k?=0
and their orthogonal trajectories,
x? + y?—2hy = + d? (See Note 2)
corresponds to a sheaf of lines and a sheaf of conics.
The geodesics v = constant correspond to the lines x = constant i. e.
to the diameters of the parabola x?—=y. The entire real part of the sur-
face S is represented in the xy—plane by the strip y = C y= C/e
and in the xy—plane by the strip included by the curves x? = y — C?
and x? = y — C’/e*. Thecircles of (8) tangent to the line y — C/e go over
into a system of straight lines enveloping the parabola x? — y — C?/e?.
Since the representation given by (8) is conformal it is interesting to
note that the lines y = constant may be considered as the envelop of a
system of circles of constant radii and centers on the x axis given by the
equation,
(x — B)?+ y? = C?/k?
corresponding on the surface to the geodesics,

DISCUSSION OF THE TRANSFORMATION,
The entire upper part of the xy—plane is represented inside the circle
g24+¢2__¢=0
The circles x? + y? — 23x + 3% — C?/x *=0 become the straight lines
(ae 3200 2 4+ C2) Gh ba te pa = CO?
The straight lines y = k go into a sheaf of conics,
(k? + 1)¢? — (2k* + 1) + §* +4 k?=0 _ through the point
(0, 1). And since —(k? + 1) is always negative the conics are all ellip-
ses. The real part of the pseudosphere is therefore represented in the area
included between the ellipses corresponding to the lines y — C and y= C/e.
N All the ellipses are tangent to the cir-
cle at the point (0, 1) and have their foci
on the ¢—axis. The circles concentric at
the origin become the lines ¢ — constant,
chords parallel to the g—axis. The system
of circles with centers on o—x and pass-
ing through the point a,b goes over into
the system of straight lines through the
point
§ = (a)/(a? + b? + 1)
C == (a* => 'b?)/(a® bt)
Fa. Mikes such systems properly related and
Fig. 2. having the point (a,b) on the same line
y — b go over into the two projectively related sheaves of lines whose cor-
responding rays intersect on the conic corresponding to y—b. In par-
ticular, in case the points (a,b) are on the x—axis the conic becomes the
circle o—b aud the corresponding rays are at right angles. Circles with
the centers on the x—axis and of equal radii go over into the straight lines
enveloping an ellipse. The line x — 0 goes into —0 the points being
moved along the line. _ The origin is the fixed point of transformation.

ASYMPTOTIC LINES ON S.
The asymptotic lines on the surface are defined by the equation
D du? + .2D’du.dv + D’dv? = 0 (See Note l) ... .. (12)
This becomes for the surface 8,
C) 42(07 = 67/04/24) ceive p) = (13)
and by (8) becomes in the x—y plane
ee ih) eve at Co a) ere. (14)
LoOxopDROMIC LINES ON §S.
The differential equation of the loxodromic lines of a surface are
given *by
((E)2/2/(G)2/2). - (du/dv) = tan «
Where « is the constant angle which the curves make with the curves
vy = constant. ForS (15) becomes,
(Cdu/u?) = + tan « . dy.
Hence tan«.uv+ku+O=0
This by the relation u — e”/© becomes,
Caner 62/ Give =k ei Ce Oe te ee (17)
which by (8) gives,
y === tances =k Dee oa ee (18)
This is a system of straight lines parallel to the line
Ve SS] ie Ek
and so a system of lines making a constant angle with the lines x = con-
stant. And this is as it should be since the geodesic lines v = constant go
over into the lines x — constant by the same transformation.
By selecting lines from different systems of loxodromic lines we may
envelop any geodesic except the meridians. This may be seen by changing
(17) to the form,
xsinx +ycosa + k,cosx — 0
Where if k, and cosx change so that k, cosx = constant we get a sys-
tem of lines enveloping a circle with the centers at the origin. This cor-
responds to the loxodromic lines on the surface enveloping a geodesic.

E, = (u? — Cd)?/(u?(d? — u?)) + 1, F, = 0, G, = u? and
D, — (u*(d? — 2Cd) + Cd) /(u(d? — uw?) ?)
D’ = 0), D4, =a —Ca))/ (a? = n)*/2
K, = ((u? — od)(u2(d? — 2Cd)+ Cd))/((d? — u?)(u2(d? — 2ed) + C2d?)
(Above equation is number 23 and is the equation of the Gaussian cur-
vature. )
When C — d, (23) becomes —1 or the curvature of the pseudosphere.
When C = d/2,K, becomes (2u? — d?)/(d? — u?)
Since for the surface d= u the denominator is always positive and the
numerator is positive or negative according as
Qu? — d*= 0
That is, according as u >(d/(2)'/*) and Bae (d)/((2) 4/7) or —(d/((2)1/?)
Ean (C2) 2) eee One — re d/((2)1/?) , =0. This means that for
the particular surface S, defined by d = 2C the Gaussian curvature is zero
for the circles u = et given by taking the distance d on the tangent
whose inclination to the z—axis is ~/4 or (37)/4. Tangents to the tractrix
whose inclination to the z axis is something between 7/4 and (37)/4 give
the curves u = coustant along which the surface have a negative curvature.

When C d/2 we have from (23) K, positive, negative or zero according
as (u2—cd) =0. But C C, and
for the trivial case u — 0 no matter what the value of d.
The geodesic lines on the surfaces S, may be studied if the surfaces
are divided into classes according as d = 2U.
In the case d — 2C the general integral (26) takes the form,
vy = { ((d?r)/(2u)) ((du)/((a? — u*)(r? — u?))
which when u = 1/t may be written as
v = — (—a*r)/2 f (t2dt)/((a°t? — Yet? — 1)
Here R(t) = dr? t* — (d? 4+ r2)t? 4+ 1. It is evident that this is exactly
the same as the R(t) of the general case if we replace d? by a and r? by b.
Taking note of this we may write the geodesic lines in terms of t
Gh se bar
v = (—1/2r) (1/6 (r*—d?)u + (o’/o}(u+v) 4 (0’/c)(a—v)) + 4
where u = p—+((r2—d2)/(2dt—2) + pv) and v xe Deano 2_ 2) /(12). In this
case the geodesics are real for all values of r.
153
In particular when d = 2C and r = d (29) becomes
v = + (d/2ua) + (1/4) log (d—u)/(d+u) + 4
For the purpose of illustration let d = 1 then (85) becomes
vy = = (d/2u) = (1/4) log (1—u)/(1+u) — d
And since J is an added constant we may without loss of generality let
6+ 0.
This particular geodesic line has been drawn in figure 3. It is to be
noted that the line winds around the surface as it approaches smaller
values, and then again winds around approaching the circleu = i. The
lines r = d = 1 are all similar to this one and may be obtained by giving
different values too .
When d=2C , k = (d? — 2Cd) is positive and ab is positive and since
k, = Cd? is always positive and we have K always real so that the geo-
desic lines on the surface S, defined by d > 2C are all real.
When d < 2C , k = (d? — 2Cd) is negative and ab is positive or nega-
tive according as re | k,/k | or - | C7d*)/(a? — 2Cd | So that on the
surface S, defined by d<2C, K will be real or ams according as

AsymprTotTic LINES ON §,.
From the general equation of the asymptotic lines on a surface we get
for the asymptotic lines on 8 ,,
(u2(d? — 2Cd) + Cd3)1/2/(u((Cd — u?)(d? — u?)!/?)) du = 4+ dv
(The above equation is number 37).
The substitution of u*(d? + 2Cd) — Cd* =1/t? reduces (37) to the form,
(—kdt)/((1—k ,t?)((at? — 1)(bt? — 1))1/? — 4+ av.
Where k = d? — 2Cd, k, — Cd’, a— Cdk + k,, b= a+ k,.
In the particular case when d= 2C (37) becomes

tion u2(d?— 2Cd) + C7d? = (C24 °t2), (t?— 1) reduces to the form,
((2C0 — d)(t2dt)) /((t? — 1)((a2 — 2Cd)t? — (d — C)?”)1/? = + tana- dv.
(The above equation is number 43.) This may be put in the form,

(The above is equation 44.)

Where pv = (1/12)\5k?—1) 3
Then k?t? — k? + (kk? — 11)/(pu — pv) + ((k2/4)(k?—1)”)/(pu— pv)?

We have then the loxodromic lines on the surface S, given in terms of f
by the equations,
u?(d?— 2Cd) + C?d? = (C2dt?)/(t? — 1)
Vv = 6(t) + 0”
where ¢(t) is given in (46) andu — p— ‘( (2/(k?— 1) (t—1)) + pv) v= p—!
((bk2 — 1)/(12)) a cS
Since k, — (d—c)? is always positive it is to be noted that ¢(t) is
always real.
In particular when d — 2C the equation, the general equation for the
loxodromic lines reduces to,
((d?/2)/(u2(d? — u2)!/?) du = + tanec: dv Ps (50)
and therefore ¢
(Stole Sih A) = SE ti nliceo 47 SS OS cuss (47a)
and these by the substitution ((d?—u?)?/? Qu) = y, V = x are given in the
x-y plane by the straight lines,
ye == SE Nee 25 ol” .... (48)
But this is the system of lines into which the loxodromic lines of the
pseudosphere may be transformed. Hence the loxodromic lines on S and
S, (when d — 2C) may be represented by the same set of straight lines in
the plane.
Suppose d = 2C — 1 and 0” —Oandthetanx —1. Then 47, becomes
( —(d? — u?)!/?)/(2u) = +4 v.
This gives a line on the surface from the point u,,v,) — (1, 0) making an
angle of 45° with the lines v = constant. The line winds about the surface
as shown in figure IV.

S
The surfaces S, might have been classified according as d—C. The
advantages of such a classification are not apparent in the analytical work
and can only be seen from the geometry of the surface or the generating
curve. In the work as presented the pseudosphere comes in as a special
case of the surfaces S, when d<2C, while if the classification had been
made as above indicated the pseudosphere d — C would be the dividing
surface in the classification. On the whole I think the classification
adopted is to be preferred. See figures V & VI for the different types of
generating curves d>C, d=C andd ee Mize Sh cco ee a oligo oh cae elie ae dale eae oe iG eee otc te oe 85
