This is a digital copy of a book that was preserved for generations on library shelves before it was carefully scanned by Google as part of a project
to make the world's books discoverable online.
It has survived long enough for the copyright to expire and the book to enter the public domain. A public domain book is one that was never subject
to copyright or whose legal copyright term has expired. Whether a book is in the public domain may vary country to country. Public domain books
are our gateways to the past, representing a wealth of history, culture and knowledge that's often difficult to discover.

IjOVU Jeah Makie Oadbkntom, member c^ the Senate, and
of the Institute of France, professor in the Musenm of Naturd
History and in the Coll^;e of France, &c. be, was bom at
Mtmtbar, in the liepartiiwat of the Cote (fOr, on the S9tb May
1716. His father, Jean Dauhenton, was'a notary ra that place ;
bis molber''8 name wu Marie Pii^ienot.
He was distinguished fmn tus cliiMhood by the gentleness of
bis Bianoers and by lus ardoor for laboar ; and he obtained from
the JeHiits of DiJiHi, with whom he commenced his studies, all
those IhtJe distioctioDs which are »o flattering to youth, withont
being always the ^^cursors of more durable success. He che*
riflfaed the remembrance of them wkfa pleasure to the aid of hia
life, and always preserved their written testimomals.
AAer he had Ihushed, under the Dominicans of the same dty,
what wasthni called a course of philosophy, lus patentee who
intended bim for the diurcb, and bsd made him assume the ec-
desastical habit after the age of twelve years, sent him to Paris
to study theol<^ ; but, periiaps inspired with a presentiment of
what he was one day to become, the young Dauhenton devoted
himself in secret to the study of medicine. He attended', at
the sdiools c^ the Faculty, the lectures ot Baron, Martineng,
and Col de Yilburs,— and in that same < Jardin des Flantes,* of
■ K<*d to the Kofsl lattttute of Fnocs..

which he was afterwards so great an ornament, those of Win-
slow, Hunnuld, and Antoine de Jusaeu. His father's death,
which happened in 1736, leaving him free to follow his inclina-
tion (^>eiily, he took his degrees at Reims in 1740 and 1741,
and returned to his native place, where he limited his ambition
to the practice of his art ; but his destiny reserved him for a
more brilliant theatre.
The little townrin which heJnts bom, had also given birth to a
man, whose independent fortune, personal and mental accomplisb-
mentg, and Tiolent taste for pleasure, destined him for any cdreer
but that of science, to which, however,he was incessantly drawn by
that irresigbble propensity, the almost unfailing indication of ex-
traordinary talents. Buffon, for it is he of whom we speak, l<Mig
uncertain as to the object to which he should t^piy bia genius,
directed his attention successively to geometry, physics, and agri-
culture. At length, his fnend Dufay, who, duiin^ his ^ori
adnsiiiistration, raised the ' Jardin dies FJantes' from the deplor-
lible state into which it had mnk by the inacUvity of the fint
j^ysimns, who were until then siq>erinteDdaBts of that esta-
hlidimeot, having bestowed upon him the reverNon of its charge,
Butfon''s choice was ultimately, fixed upon natural' history, mid
he «aw opening, before him that vast career whidi he pursued
with so much glory. He at first measured its full extent ; he
perceived at a glance what he had to do, — what it was in bta
pow» to accomplidi, — and where the aid of others would be re-
quiute.
Overloaded from its commencement wilii the undigsated eru-
dition of Aldrovaodus, Gesner, and J^hnstoD, natural histery was
afterwwds mutilated by the nomendaUira. Hayv Eleiny even
Linnseus at that time, preseDted nothing: but bane catalogues,
written in a barbarous language,' and vluQh,1rithaU.tii^«ecn)au

tw«eD nature and him, and bis eloquence seemed to exocise iu
self agwist his own reason, before naploying itself in mislead-
ing tliat of otbers.
' Daubenton, feeble in his bodily constitution, geode in his
aspect, and possessed of a nioderadon which he owed to nature
as much as to his own wisdom, earned the most scrupulous tst'
cum^)ection into all his researches. He believed and affirmed
(Hily what he had seen and touched. Far Irom wishing to per-
suade by any otlier means than strict evidence, he carefully
avnded in his conversation and writings every tiling figurative,
every expresaon that might produce deception. Possessed of
irarnqvaUe patience, he never intennitted his exertions ; he went
over the same.investigation again and again, and by a method,
p«^aps too rare among the cultivators of real science, all the
faculties of his mind seemed to unite in imposing ulence uptm
his ima^natioB.
Bufitm though he hod only taken a laborious assistant who
would level the inequalities of the road, but he found a faithful
guide who pointed oiit to him the false paths and predjnces.
A hundred times did the biting smile which escaped his friend
when he percfflved scHDething doubtful, bring him over from bis
first ideas ; a hundred times did one of those words, which thi^
friend knew so wdl to apply at the proper time, arrest him in
his headlong progress ; and the wisdom of the one thus allying
itself with the energy of the other, gave to the History c^ Qua-
dHiped^ the wily one common to the two authms, that degree
of peifeotion' which renders it, if not the most interesting of
those which enter into the great Natural History <^ BufKu, at
least that which is the most exempt from error, and which will
longest retain a closaied character among naturalists.
It was, therefore, still less by what he did for him, than by
what he prevented him from doiBg, that Daubenton was useful
to Buffon, and that the latter bad reason to congratidate himself
for having f<»ined such a ecMinection.
It was about the year 174S that be took him to Paris. The
office of keeper and demonstrator of the Cabinet of Natural
History was very imperfectly discharged, and the person who
possessed it, a M. Noguez, having long;reuded in the country,
its duties were petformed from time to time l^ some <^ the

people ccMiDected with the girden. Buflbn mired it for Dau-
-bentiw, sDd it was coofared upon him by iHcret in 1745. Hii
salary, wfaid) at first was only 500 ftano, was gradually aug.
mented to 4000. When fae was only asnstant in the Academy
of Sciences, Bufibn, who was treasurer, made htm several prfr-
sHits. On his arrivai in Paris, be also gave bim an apartment
In a word, he neglected nothing to ensure him the comfort ne-
cessary for every man of letters, and for every perstm engaged
in the cultivation of science.
Daubenton, on hie part, devoted himself witbmit intarmiasioD
to the labours cdcutiUed to second the views of las bcneEactor,
and by these very labours he erected the .two princapal monu-
ments of hi« own glory.
One c^ these, although not a printed botdi, is not ^e less a
very beautiful and a very instructive voIume,8ince it is almost that
of nature. I allude to the Natural History Cabinet of the * Jar-
din des Plautes.' Befwe Daubenton's (ime it was a mere drug-
dup, in which the products of the j>ublic courses of chemistry
were collected, to be distributed to the poor who might have
need of them for the cure of ihdr diseases. Is Natural Histwj^
jHoperly so called, it only contiuned some shells collected by
Toumefort, which had afterwards served to amuse the child-
hoi>d of Louis the Fifteenth, and of which several^stUI bore the
marks of his humours.
In a very few years it entirely changed its appearance. Mi-
nerals, fruits, woods, and shells, were ccdiected from all parts,
and laid out in the best order. The means by which the vari-
ous ports of organized bodies m^bt be {M'eserved, were made
an object of discovery and improvement. The inanimate spmls
of quadrupeds and turds resumed the appearances of' life, and
presented to the observer the minutest details of their charac
\en, at the same lime that they astonished the curious by the
variety of their forms and the brilliancy of their colours.
Previous to this, the cabinets of natural productions were
indeed ornamented with some riches ; but those were rejected
whicb might ^xnl th^r symmetry, or take away the appearance
of decoration. A few naturalists collected the objects which
might assist them in their inquiries, or give strtegth to their
oinnions; but, being limited in their fortune, they were obliged

Daubenton, supported by Bufloiii and'pixrflting by the re-
sources which the influence of his friend obtained foi' 'him frcna
ihe government, conceived and executeda more extetteiv^^Q :
lie thought that none of the prodnctions of Nature ought to be
kept back from her temple; he perceived- that such of these
productions &a we look upon as the most importaat, can only be
well known, in so for as ^ey are coinp)it<^ with all the others ;
that there is not even one of theni which) by its numCTOUS riitf-
tions, is not more or less directly connected with the refit of na-
ture. He therefore excluded none, and nude the greatest efforts
to-fc(rf!ect dl. In particular, he made an extehsive collecticm of
Anatomicid prepanttions, which long dbtinguished Ae Parisian
Cabinet, and whidi, although less t^^reeable to the vulgar eye,
are of the greatMt utility to the man who does not t«nflne his
inquiries merely to the surface of created beings, and vho strives
to render tiatural history a philosophic^ science, by making it
also explain the phenomena which it describes. ■-
The study'and arrangement of the&e treasures becameto him
a true passion, the only one perhaps that he had ever been re.
marked to possess. He shut himself up for whcde days in the
(iaHhet, ■ He there Himed over in a thousand wa^rg the objects
which he had brought together, scrupulously exunined all dieir
^rts, tried alt the ai^ruigements' imaginable, unti] he fell trpAa
that which nether offended the eye, nor broke asunder natural
relations^ ...:,.,
This taste for the arrangement (^ tt cabinet revived' with
energy in his UfSt years, when our victories broiight k new mass
of 'riches to iChe Calnnet of Natural History, and circumstances
p^rtrlHted the whole to assume a greater deveJojmrtnt At the

■The second mtmuBient which Uaubentoa l«ft, was, acocitding
to his onginal ^an, to have be«i a complete descnptioa.of the

pUBvented him froiB extending this description beyond the qua-
drupeds.
This is not the place for analyzing tlie descripUve pert of the

astobisfaiiig in the boMnesB of its ptan, — or for unfi^ingalL that
it contains of what is new atid imp<xtant to the naturalist. To
give gome idea of the work, it is only neceesary to state, that it
oottajns tile depcnptitm, internal as well as external, of a hun-
drad and eigjity-two ^>ecies of quadrupeds, of which fifty-eight
bad Derer. been dissected, and of which thirteen' had not .even
been externally described. It contains, inweover, the external
descripCiDn alone of twenty-two species, of which five were pre-
viausly unknown. The number of entirely new species is there-
iare:eighteen; but the new facts relative to those which were
already more or Jess super6<aally known, are innumerable. The
greatest merit o£ the wwk, however, is the order and spirit with
which these descnptioos are given, and which is the same with
K^ard to all tlie ^>edes. The author has been heard to say
repeatedly, that he was the first who had establtshed a true
Goaapanitvra anatomy ; and the assertion was true in this respect,

to any system, he hu bestowed an equal attentian on all tbe
parts, and could never be tempted to nc^ect or dtaguise what
was not conformaUe to the rules which he had esuUisbed.
. However natural this method must appear to penoos who
only judge of it by mere good sense, it is far from being yery
cwy to follow, since it is so rare to be met with in tbe wtx-ka of
other naturalists, and there are so few ammig them who have
been at tbe trouble of placing the beings which they describe,
otherwiae than as they are in th^r systems.
Daubmton^s work may be considered as a rich mine, in which
tbe naturalists and anatomists who engage in the examination of
quadrupeds are obliged to dig, and &odi which several writers
have extracted mwiy precious articlet, wilfaout acknowledgment.
It is sonietimeg only necessary to make a table of Iiis dwerva.

the most striking results ; and it is thus that we ought to under-
stand Camper^B expresoon, that Dauienton did not knoa> ail the

He has been reproadied with not having traced the table of
these results himself. It was with good reason, however, that
he av<»ded an (^)eratioa which might have flattered his seIf.lovr,
but which would have led him into errors. Nature had beoi seen
by him to exhilnt too many exceptions, to allow him to imagine
he could establi^ an order in her evolutions; and his prudence
has been justified, not only by the ill success of those who have
been more adventurous than himself, but even by his own exam-
ple ; the only rule whicii he ventured to trace, namely, that sup*
posed to detnmine tbe number of tbe cervical vertebra, having
been found, toward tbe end of bis career, to be incorrect *.
He has been also Mamed for having oonfined his dissections
within too narrow bounds, having Iknited them to tbe descrip-
tiiRi of the skdeten and viscera, without treatii^ of the muscles,'
vessels, nerves, or external organs of sense ; but it cannot be
jwoved that it was possible for him to have WMded diis re>

curaues, and de§dtute of all those details, which it was phyu>
ea&j and morally impoasibls for Buffon to fumish.
These imperfectiotis were still more obvious in the sup[^
ments, works composed by Bufibn in his old age •, in which that
great writer carried his injustice bo £u-> aa to entrust to a more
painter the part which Dauboiton had ao well executed in the
first volumes.
Several naturalists endeavoured to suf^y the defect, and,
among others, the celebrated Pallas took Daubentcm for his mo-
del in his Miscditmea and Zooloffical Gkaningty as well as
in his History ^ihe GUres; works which ought to be considered
as tbe true suf^emenu of Buflim, and as the best accounts tliat
have appeared of quadrupeds, next to his great work.
Every body knows with what success, in the departments of
Fisbes and Reptiles, tbe illustrious continuator of Bufi<m, De
La Cepede, who was also the friend and colleague of DaubentoOf
and who sUll laments him with us, has employed in his writings
tbe double advantage of a flowery and figurative style,- and a
scrupulous accuracy in tbe det^ls ; and how he has equally rival
led hia two jMcdeceseors in th^ pecular excellendea.
Dsubent<»i, however, so far forgot the little injuries of his
(dd Mend, that he afterwards <x»itributed to several puts of tbe
JSitloire Naturdle, although bis name was no Icxiger atlacbed
to it ; and we have evidence that BuBbn had coosulted the
whole manuscript of bis lectures in tbe College of France, when
he wrote his Hitioire det Mmeraux\. Their intimacy was
even perfectly re-established, and ctmtinued until Buflbn's
death.
During the eighteen years which the fifteen quarto volumes
of the Hist4»re des Quadrupedes took in appearing, Daubenton
was (mly able to ^ve a few memoirs to the Academy of Saences;
but be subsequently indemnified it ; for we find, in the ctdlection
of the Academy, as also in that of the Medical and Agricultu-
ral Societies of tbe National Institute, a coneiderable number,
all of which cmtain, as well as the works which he published se-
parately, interesting facts or new views.

The bare enuneration of dwdi would eioeed the liodts tA a
diacourse like the present ; and we shall ctxitent ounelvea with
biiefiy mmtioning the prindpal discoveries with which he has
enncbed several departments of human knowledge.
In zoology, Daubenton discovered five spedes of bats * and
a Borex -f-, which had escaped the jwtlce of other naturalists, al-
though all pretty common in France. He gave a complete de-
9caipti6n of the species of small deer which produces the musk,
and made some curious remarks on its organization %. He de-
scribed a singular conformation in the organs of the vcnce tn some
foreign birds ||. He was the first who applied the knowledge of
comparative anatomy to the detenninatitm of the spetnes of quad-
rupeds whose remains are met with in a fosul state ; and al-
though he was not always happy in hie conjectures, he never-
theless opoied an impcHtant field of investigation in the history
of the revolutions of the globe; he destroyed for ever those ri-
diculous ideas of giants, which had been renewed by each guc-
cessive discovery f£ the remains of sonie great animal §.
His most remarkable achierement of this kind, was the deter-
mination of a bone, which was kept at the Garde Meuble
SB the 1^-bone of a giant. He discovered, by means of com-
pozative anatomy, tbot it could only be the radius of a ^rafl^,
although he had never seen that animal, and although no figure
of its skeleton existed. He hod the pleasure of veriiying bis
conjecture himself, when, thirty years after, the museum {ho-
cured the skelettM) of that animal which it still possesses.
Befiure his time there were only vague ideas respecting the

to the subgect, and of having done all that his means rendered
poedble.
By these labours he had acquired a sort of popular reputa-
tion, which was very useful to him in a season of danger. In
1798, a period already fortunately remote from us, when, by a
derangnnent of ideas which will long be memorable in history,

irhich formed a part of Daubentoa's chafacter.
It had long been a subject of complaint, that there were no
public lecturea on natural history in France. He obtained, in
VnS, an order that aas of the chairs of practical medicine in
the college of France, should be changed into a natural history
choir, and in 1775 he undertook to fill it. The Intendont aC .
FariS) Berthier, engaged him, in 1783, to give lectures on rural
economy, at the Veterinary School of Alfort, at the same time
that Vicq d^Azyr delivered lectures on comparative anatomy,
and M. de Fourcroy on chemistry.
He also wished to give lectures in the Cabinet of Paris, where
the (Ejects of natural history would have spoken with still mam
perspicuity than the professor, but not being able to oht^n per.
miiKdon under the old regime, he joined along with others em-
ployed in the Garden of Plants, in soliciting the Convention
to reniodel that establishment into a regular school (^ natural
history,
Daubenton was named Professor of Mineralcgy to it, and he
fulfilled the duties of this office until his death, with the same
correctness which he employed in all his functions.
It was truly an affecting thing to see this old man surrounded
by his pupils, who received with a religious attention his words,
which thnr veneration seemed to convert into so many oracles ;
to hear his feeble and tremulous voice become again animated,
and resume strength and energy, when he had to inculcate swne
of those great principles which are the result of the meditations
of genius, or only to unfold some useful truths resulung fnHn
them.
He had no less pleasure in speaking to his pufnis dtan in hear*
ing them speak : it was seen by his amiable cheerfulness, and
the ease with which he answered all their questions, that the oc
cupation was a true pleasure to him. He forgot his years and
his weakness, when he had an opportunity of b^g useful to his
pupils, and of fulfilling his duties.
One of his colleagues having offered, when he was named to
die office of senator, to. relieve him in his teaching; " My
Friend," he replied, " I cannot have a better substitute than

Nothiug^ can better prove his zeal in befaalf of the studenta,
than the paioa which he took to keep up with the prografis of
icience, and not to imitate those prc^easers who, once fixed in a
ntuadiM, never vary th^ lectures. At the age of eaghty, he
was seen d[>taining an explanation of the discoveries of one of
, bis oldest pupib, M. Haiiy, and labouring to apprehend them,
t^at he might be able to impart them agmn to the young peoplo
whom he taught. Such an example is so rarely to be met with
among the teamed, that it must be considflred as one of the finest
MtaXa in Daubenton^s character.
During the ejAemend existence of the Normal School, he de-
livered some lectures there. He was recced with the most
llYely enthusiaam whenever h^ made his appearance, and iq>-
pkudfid, as often as he introduced Uie sentiments by which that
numerous autUtory were animated, and which they rejoiced to
tee ppeseased by Uie venerable old man.
We have now to speak of some of his works, which are less
destiDed to make known discoveries, than to give a. systematic
dCOouBt of some body of doctrine ; such as his articles for the
^wo £ncycl<^>»diaA, and e^Kcially for the Encydopedie Metho-
4ique; in which he composed the dictionaries for quadrupeds,
i;ep^e», and fishes ; bis Tableau Mmeralogique, and hie lee-
mres at the Normal Schcxjl. He has left the entire manuscript
of Uioee of tbe Veterinary School, of the College of France,
and of the Museum. It is to be hoped that they will not be
withheld from the public
These didactic writings are remaricable for great perspicuity,
EDUnd principles, and a scrupulous exclusion of every thing
doubtful. The only astonishing thing in them, is to see that the
man who had reasoned with so mudi force against all clasMfica-
tk» in natural history, should have ended with adopting ai^.
rang^nents which are neither better dian, nor perhaps so good
as, ^ew witb whidt he found fault, as if he bad been destined
to |VOve by tas own example how much bis first prejudices were
eaOtfXfy to the natute of diings and the constitution of man.

It seeBwd naturally to arise from the circumstance that he

every thing that related merely to reasoning. To approach him
was to love him ; and never did any man receive more numerous
teitimonies of affection and respect from others, at all the periods
of hia life, and under all the succes^ve governments.
He has been reproached with having submitted to a homage
unworthy of himself, and odious from the very names of those
who rendered it to him ; but this was a consequence of the sys-
tem which be had adopted, of judging even public men by their
words, and of never suspecting any other motives than they ex-
pressed : — a dangerous method, no doubt, but one which has
perhaps been a little too much abandoned at the present day.
Another dispo^tion of his mind, which also contributed to
those odious imputations of pusillanimity or self-conceit which
have been brought against him, even in printed works, and
which, however, does not the more justify them, was his perfect
obedience to the law, not as being just, but simply as law.
This submission to human laws was absolutely of the same na-
ture as that which he had for the laws of nature; and he no
more permitted hiras^ to murmur against those which deprived
him of his fortune, or of the rational use of his liberty, than
agtunst those which caused his limbs to be deformed by the
gout. Some one has said of him, that he observed the knots on
his fingers with as much coolness as he would have observed
those of a tree; and this was true to the letter. This was
equally true of the omlness with which he would have ^ven up
his offices and emoluments, and gone into exile, had the tyrants
required it of liim.
Beddes, admitting that when the m^iitenance of his tranquil,
lity might have been the motive of some of his actions, will not
the use which he made of that tranquillity justify him ? And
this man, who could ^nest so many secrets from nature, who lud
the foundations of an almost new science, who gave to his coun-
try an entire branch of industry, who erected one of the most
important monuments of science, who formed so many accom-
pUshed pupils, of whom several have already attiuned the high-
est rank among the learned, will such a man require, at the
present 'day, that I should justify him for having managed tfae
means of drang all this good to his country atid to humanity ?

against his accusers ; the last and motit aolemn marks of tbeir
esteem terminated, in the most glwious numner, the most useful
career; perhaps we have to regret that they sborteued its course.
Having been named a member of the Conservative Senate,
Daubenton wished to perform his new duties in the same man-
ner as he had done those of his whole life, and was in conse-
quence obliged to make some change in his r^;;imea. The sea-
son was very severe. The first time that he assisted at the ses-
aons of the body which had elected him, be was struck with
apoplexy, and fell senseless into the arms of his astonished c<^
leagues. The most prompt assistance could ooly restore him to
feeling for a few moments, during whidi he shewed himself
what be had always been — a tranquil observer of nature; he
felt with his fingers, which still retained sensation, the various
parts of luB body, and pointed out to the assistants the progress
of the disease. He died on the 31st December 1799, aged
eighty-four years, without suffering ; so that it may be said c^
him, that be attained hapfnness, if not the most ^endid, at
least the most perfect, and the lea^ mixed, that man could h<^
to attain.
His funeral was such as was merited by (me ofour first magis-.
trates, me of our most illustrious men of science, and one of our
most respectable fellow-citizens. The citizens of all ages and ranks
con^dered it an h(»)our to render the testimony of their vene-
ration to his ashes. His remains were deposited in the Garden
which had been embellished by bis care, which his virtues had
honoured dunng sixty years, and of which his tomb, according
to the expression of a man who does equal honour to science
and the senate, will form an elysium, by adding to the beauties
qS. nature the charms of feeling. Two of his coUeagues have
been the eloquent interpreters of the regrets of all who knew
him. Pardoo me, if these punful feelings still affect me to such
a degree, that I can only be the interpreter of die public grati-
tude ; and if they lead me from the ordinary uine of an acade-
mic eulog^um, pardon him whom he honoured with his friend-
ship, and of whom he was the master and the benefactor.

f ROM the circumsttince of the original proposal of the project
for reaching the Pole,'by a journey over the ice, having bCMI

renew the subject, after a lapse of thirteen years, in the hc^
notwithstanding the recent failure of Captain Parry in tbia sBBOe
adventure, of still justifying the proportion, upon the very plan
originally suggested, and irf proving to the Society, that the
prd}ability of success, if at all diminished, is by no means ovtf-
turned.
Hitherto I have studiously fcrbome to make remarks on rt>e
various expeditions of late years employed it Arctic exploratioAB,
for reaaons not necessary to be named ; but any longer to re-
main silrat, nfter the recent result, ^t^ould indicate, either that

and to the country by iHiidi the expence <tf the Rcratt explMA-
lioa and experiment is borne, to itate tbe reason I have for be-
lieving that the Britisb flag, under moM happy arrang^eiaentts
might yet be planted upon the Pde.
Had the expedition, indeedjof Caption Parry proved flucceas-
fill, I ^lould have Wt It to the puUie to do me the justice (^
having first suggested the fdan of this mode of afrproach tn
the p^e ; but as, in ccmsequence of its failure, no credit is to be
acquired by claiming it, I may, without the selfi^ charge which
mi^t have attached to such a dafan, under cbvumstances dl
complete success, be bold to acknowledge the project, as well as
ready to defmd it.
My object in this oommunicatioo, as just intimated, is to
[ODve, that, whatever probat»lity tiiere at any time was of
nachmg tbe pde, by a journey over the Joe, remans little. If at
aU» diminifdted by the late experiment of Captain Parry ; be>
cause there were two drcumstauces in tbe plan of it, (and it is
somewhat lemarkaUe^ that these are almost tbe oalj matofal
deviaticMiB from the original plan that I have been aUe to dis*.
cover), either of which a{^>eared tu tne obviously blal to the 8U<V
oew of the expedition. And, besides these two grounds vf fail-
ure, both capaUe of being anticipated, by a thorough acquaint-
ance with tbe nature of the Spitzbeq^ ice, there is anothw
that baa hem disdoeed by the peculiar difficulties of the recent
exp^maH, which, equally with the other two, must have «»-
tributed to the iidlure. Respecting the importance of theee
aHiaderadons, however, it will be for tbe Society and the pub*
lie to judge, whether they are indeed essential coonderatimis [
and if so, whether, under a difiWent arrangement, e much
greater prepress, if cot on entire execution c^ the project, mi^it

pedition *, it might seem captioiu in loe to start Directions, or
presumptuous to think of proposing a better plan ; but I would
venture to appeal to the opportunities for observation, and the
extensive experience which twenty-one voyages to the Green-
land whale-fishery have afibrded, for forming adedded pawmal
judgment, in respect to an adventure of the nature of that under
consideration.
But I proceed to state the several craisiderations in the ^an
of the expedition, all capable of a different arrangement, to
vhich I have referred above, as essentially affecting the result <rf
the expedition. These are. The weight of the siedge-boats ;
The season of the year at which the experiment was tried ; and,
lastly, 7%f meridian upon which the party traveSed.
I. In regard to the Weight of the Sledge-Boats.
The mode of travelling, by which it always appeared to me
that the journey to the pole might be attempted with the great-
est hope of success, was by light sledges or sledge-boats, drawn
by dogs or reindeer ; but in the event of the fulure of these
animals on the journey, it did not seem to me impossible (and
much less so since the expedition of Captain Parry) thiri the
return, or indeed the whole journey, might be effected on foot,
with hand-sledges for the provisions and aj^ratus-f-. The
sort of sledge I suggested " might consist of slender frames c^
wood, with the ribs of some quadruped for lightness and
atrength, and coverings of water-proof skins, or other materials
equaUy light |.'" Something of the nature of ibe Esquimaux
umiak, or women's boat,, for instance, which, although 30 feet
or upwards in length, and capable of carrying from ten to twenty
persons, besides their domestics and fishing utensils, is yet so
^ght, that, when the Esquimaux are performing a voyage in it

will, I believe, appear evident from a perusal of the foregoiog pages ; nor can
I, afl«r much consideration, and some experience of the various difficulties
wbioh belong to it, recommend anj material improvement in the plan lately
adopted."— A'VimitiM, p. 1 43.

(which they aometiiDes do to the extent d 100 or 80O miles),
and meet with any interrujrtitxi, six or ^^t persons can take
the boat upon their heads, and carry it over either land or ice
to the next oonvaiient place of emlxtrkatioD * A boat of a de-
scription somewhat resembling this, but snialler, and placed upon
a li^t sledge-fnune, or cradle of wood, would, I apprehend,
answer the purpose ; for whilst the lightness of its structure
would render it easily piatable, the sledge-frame would defend
it from being cut or chafed by the ice ; and, indeed, whenever
any cut or rent might occur, the fissure, after the manner of
the Esquimaux, could be eanly and expeditiously repaired.
The great difficulty always expa^enced in launching whale-
boats over the ice, — a means which must often be resorted to in
the whale-finery, either when boats are upset or an entangled
whale takes refuge within a close boundary of ice, — forcibly im-
pressed me with the conviction that no boat of ordinary w^ht
could possibly be. used in performing a successful journey to
the pole. And, on reading Captain Parry^s narrative of his
late experiment, I was much more struck by the immense dif-
ficulties Aeir hearty exertions maUed them to surmount, not-
withstanding all the disadvantages under which they laboured,
than by the want of greater success. And in farther proof <^
my [»evious personal conviction of the vital importance of the
weight of the boats, I may be permitted to mention the fact,
that, when I £rst heard from a near relative of Captain Parly's,
whilst the expedition was yet abroad, that the sledge-boats w««
each of the weight of near three quarters of a \aa, I expressed
the strongest conviction that this circumstance alone muit be
fttal to success ; and I moreover added, that, from my inti-
mate knowledge of the nature of the ice, and the difiiculties to
be ^countered, I should feel perfectly secure in venturing any
consideration iriiatever in support of the belief that it wat tm-
possii^ to succeed f.

(bWitig, ito d^bt, ib one eaeenti^ respect to the state of th6 i«e),
that Captain Party informs ub that the moet of the jourAey was

tance travelled was no less than 078 miles *, being aufBcient,
could it have been j)etf«mii«d In a direct line, to teadi within
two degrees of the pole, and return !
N6W, the only question in regard to this argumoit is, Whe-
dier, in the unfavourable and unexpected state in whicJi die
ice wte found, and I may add unustial state, with a dedge^boat
of light materials, such as I have briefij deeoibed, they coi^

I speak not here of the ol^eetion of any want of safety in sudt
a ctmveyance, in the event of having to cross large openings td
Water, for that will be considered hereafter. The concludcm I
should draw from reading the narrative is, that, in a sledge
boat of 400 tt>. or 500 Vb. weight, instead of 1540 lb., widi
hand-sledges for ^>pBratu8, &c tha« would seldom have been
occasion to go over the same ground twice. Of this, however,
t can give no proof, neither can any one ; it is merely a matter
of judgment, and that judgment can only be valuable at satia-
&ctory accOTding to the relative experience and capcdiilitieB (rf
the persons whose opinions may happen to come into competi-
tion. At all events, It must be pafectly certain that a ttdue-
tion of 9000 lb. wdght in the two boats, out of 7506i, being
more than on&iburth of the total weight, and dimioilhing by
^penditure of stores to one-half, must have afforded a cbmce
of success very tax heytnld the extent actually accomplished.

But the w«ght of the £oata Was not the only conddem-
tion that essettt^ly affected the final result,— tbe BBason ot
THE YSAE at which the experiment was tried waa pcriiaps Me
most wtfhiiouniMe that could hate been wlrtted. This iiHiy
appear a gratuitous asseftion, especially When put along with
CaptaJn Parry's ojanion before quoted; with which i^nion, how-
ever I am dispcMed to respectful deference, I cannot coincide,
titilesa the arguments which appear to me to be so concluave
agunst it, can be repelled and refuted.
Without stating these ai^iments ft>rmally, I shall briefly
nten^on what the views are which I have always held as to ike
best season for undertaking such an expedition ; and then the
peculiar and formidahle difficulties which Captain Pany en-
Countered, arising out of the season at which his adventure waa
undertaken, will naturally constitute both ai'gument and ground
of proof.
The original pUn which I had the honour of submitting to
die Society in the year 1815, I find, on carefully reviewing it,
as still affiwding, in my opinion, the best chance of success in
way attempt for reaching the pole ; though there are a few mi-
ner circumstances, which an experience of several additional
voyages among th6 pidar ices would now induce ue pbrhqra to
modify. But the great outline <A the plan X would still justify
bs feasible, and as being Well adapted to the peculiarities and
the difficulties of the bold adventure ; and there are few parts
of the ^n whioh I should cmisidn <^ more impcHtauce than
Uiat relating to the season for making the experiment : For Ibe
occurrence 6f detached ice and sofl snow are obstacles which
28 Rev. W. Scoresby's Rmarki on the ProbabUa^
always appeared to me so formidable, as to require, if possible,
to be avoided. To effect this, I suggested, in the original plan,
that " it would be necessary to set out by the close of the moDth
of April or be^nning of May ; or at least s(»ne time before the
severity of the frost should be too greatly relaxed *.'"
A very brief mention of the well-known changes which take
place in the polar ices on the approach of summ^, will suffice
to shew the impiH-tance of this su^estiou. During the conti-
nuance of the frost below 281°Fahr. (the freezing point of sea-wa-
ter), the small interstices among drift ice, and the greater spaces
among fields, are generally filled up by " bay-ice." So that, in'
the midst of a body of drift ice, where no original mass should
exceed 100 yards in diameter, or indeed any smaller maximum,
the whole body, in the spring of the year, is generally cemented
into a continuous field ; and titis, in situations sheltered from
the action of the sea, often partakes so much of the nature of
a field, that there is no difficulty in walking over such ice for
many leagues together, without ever requiring the aid of a boat.
Hence, in the months of April and part of May (probably ,the
whole of May in latitudes to the northward of Spitzbergen), the
entire body of the Spitzbergen and Greenland ices greatly par-
takes of the nature of continuous fields. Sometimes, indeed,
the field ice gets separated to the westward of Spitzbei^eo be-
fore that time ( but this is unfrequent. It is at that Ume,
therefore, when the drift-ice is thus cemented into field-like con-
tinuity, and when the field-ic« is often found in uninterrupted
connection, from the filling up of the interstices with bay-ice,
that the Arctic ices are unquesUonably in a better state for the
progress of travellers, than at any other season at which the
80th degree of latitude could be reached without wintering.
And at this season, when the snow is yet undissolved, and occa-
sunuUfy hard upon the surface, — -when there is no water what-
ever upon the ice, no run to impede or incommode the adven-
* I ought peili^w to apologise to the Societj for thii and aome other re-
Hnacea to my own puUicotions ; but I am under the neces^lj of doing bo,
to avoid the impuUtlon of first deriving information irom Captain Parrj's
esperimeDt, and then utiug that Information as an argument for a new plan,
flu^Mted bj the causes of the recent Mlure. M^ object in these referencei
is to prove that I am not taking up new views; but justifying the original

turns, and do aeedle-like crystals to cUstress them, — then, I
ibould conmder that the experiment would have every reason-
able chance of success.
Beades, when the ice is in this continuous and favourable
state, the adventurous party might avail themselves of the use
of reindeer or dogs to drag their hght sledges across the north-
ern fields or floes, vhich, beades affording them relaxation from
too arduous exertion, would yield a valuable reserve of nour-
ishment (however pmnful au(^ en applicaUon <^ these useful
ammab), either in case of resources failing them, or, what mig^t
easily happen, any of the provisions b^ng lost.
But on the abatement of the frost, the change that takes place
is not less detrimental to the success of a superglacial journey, than
it 13 astonishing in itself. For every whale-fisher knows by hard-
bought experience, that the cementation of the drifuice, which in
April and May presents so formidable an obstruction to the pro-
gress of a ship that it frequently costs him hours and days of
hard labour to advance a few fathoms, is in June or July socom-
j^tely dissolved, that he can often s^I through the very centre
of the same body of ice in any direction, without ever stopping ! *
And he is equally familiar with the &ct, that the tendency of
the ice, which during the frost is to form into compact streams
and continuous bodies, and tenaciously to adhere as if by gene-
ral attraction, is so changed on the cessation of the frost, espe-
aally in July and August, that the adhe^ve tendency is quite re-
versed, and there now seems to be a universal repulsion ; so that
in places where there is space for it to separate, and when there
is no action of a swell to bring it together, no two pieces of ice
can be s^d to be in contact ! What a serious obstacle such a
change in the condition of the ice, as to continuity, must pre-
sent against the polar journey, will be evidentji even to persmis
who have never witnessed the fact, without a word of argument
or illu^ration '.
It has been necessary to enter into these explanations, that
the Society may judge of the defects in the plan of the recent
expedition, whidi it is my object in this part of my communica-
tion to endeavour to point out, that no one may be obliged to

at the borders of the ice, and even ^ere it is so uncommon as
to be quite a phenomraon ;— because in May the surface of the
iee, where bare of snow, though having a granular roughness,

on the ice is unmised with water, and no pools or lakes, uniew
from cvilices adraittisg poods of se«rwater, which are not fre-
quent, occur on the floes. That the disadvantages belonging
to the season, therefore, at which the adventure was under-
taken, are great and formidable, and for the most part might
be avoided, I trust what has been said amounts to proof.
I must not neglect, however, to concede to the plan of the
recent expeditimi an accidental delay of almost twenty-one days,
DOT would I omit acknowledging that this brief space of tune
might have proved of much importance to th«r greater succeas,
by enabling them to reach the field-ice before the commence-
ment of the rains. It was the intention of Captun Parry to
have " set out from Spitsbergen, if possible, about the ban-
ning c^ June, and to occupy the months of June, July, and
August in attempting to reach the Pole, and returning to the
diipS;" but, in oonaequence of the instructions which hod been
given him, he had first to And a place of security foi the ship,

nor was the lemaiDing crew in the Hecht adequate to take

III. In regard io the Meridian upon tehich the Party travelled.
The two objections against the plan of the recent expedi-
tion that I have now urged, and endeavoured to substantiate
• — concerning the weight of the sledge-boats, and the season of
undertaking the enterprize, either of which appears to me to be
of such consequence as necessarily to be fatal to success — are not
objections suggested by the failure of the expedition, though they
receive the strongest support frova the circumstances of the fail-
ure ; hut they are objections, as I have shewn, one of which was,
and the other, had it been known, would have been, anticipated.
There is another objection, however, to the plan of the late ex-
periment already hinted at, which has been developed by the
perusal of the Narrative, and this likewise must have had a
most important influence in diminishing the chance of success ;
and that is, the particular meridian on which the expediHon
made the triai. They set out from the northern, approaching
the north-eastern face of Spitzbergen, by which, indeed, they
gained irom 40 to 60 miles of northing, beyond the ordinary
extent of navigable sea to the westward of Spitzbergen, before
they took the ice ; but this small advantage was far from being
a compensation either for the detention of twenty days, or
for the extraordinary difficulties as to the nature of the ice
which they encountered.
It is but proper, however, to state, that the choice of this
meridian rather than a more westerly one, was probably urged
by the circumstance of the Hecla having got beset in the north-
em ice, and being driven towards that meridian along with the
pack. It would not be just, therefore, to consider that so much
an error in the plan as an unfortunate circumstance, materially
affecting, as the r^ult shewed, the executicm of the project, by
throwing tbem in the way of such a roogfa and untoward con-
geries of pack and floe ice, as no human energies, circumstanced
as in other respects they were, could have a prospect tA sur-
mounting.

Id tbe plan which I had in view, when I before addressed
the Society <Hi the subject, Magdalena Bay, Smeerrabei^, or
some other of the ancbon^ea about Haltluyfs Headland, was
tbe retreat, if any were made use of, which I should have sug-
gested lor ibe ships ; iKcause, there is little fear of ice setting
down upon any of these in the summer ; and they aSord a safe
outlet for retunting even at a late seasan in the autumn. But I
should have proposed, — not to attempt to secure tbe ship before
setting out, as that, as in the case of Captain Parry, would be
liable to occasion great and unnecessary delay,— but to carry
the travelling party direct to the main border of tbe northern
ioe, either on. the meridian of Hakluyt's Headland, or a few de-
grees of longitude to the westward of it, if a higher latitude
oould be there attiuned. I would theo penetrate the loose ice,
provided it could be done without risk oi* hampenng the ship,
to obtain the chance, which the experience of some occasions
that I have seen holds out, of planting the travellers at once
upon the field-ice*. The ship, then, being left in adequate
charge, and with a full complement of men, independent of the
travelling party, might, during the next month or two, pursue
any object in the immediate neighbourhood th^ should be
deemed desirable, having first landed, at as^gned places, abun-
dant resources for the travellers on their return, in tbe event of
any accident happening to the ship. Then, in good time tor tbe
return of tbe expedition, the ship might take its station on the
face of the northern ice, and cruize between certain meridians
previously agreed upon with the travelling party. By that
means there would be a fair probability of receiving tliem upon
their return, without subjecting them to the risk of cros»ng la
their slight canoes the open space of water between Spitzbergen
and the ice. And to avoid inconvenience, in case of the boats,

In'the ten yeaia between 1803 and 1812 incliuire, the Spitzbeigen team
were unumally encumbered with ice, there having occurred but ten " open
•easons," in which access to the usual hi^iest latitudes mlgiit be bad in tbe
mDDth of April ; but during the same ten yvaze, wilh one exception, and not
gpMklDg of two oUiSr ymn in which we nude do attempt, the 8M)-degMe
of latitude was always readied during the mouth of Maj, and waa in
gents'al acces^ble by the middle of May. During tbe next ten years,
from IS13 to 1823 (Omitting 1819, when I did not visit the flBbery),
there occurred nv#n " open seasons," in six of wblch we actually proceeded
to as high a latitude as we wished (generally 711^4 to 79°), and, without doubt,
might haTC proceeded &Tther, as early as the midttte, or, at least, before tbe
end of April ; and during the other three years, out of the ten, we attained
the highest nortlieni latitudes we wished, once on the 1st, and another time
on the 4tJi, sf Hay, — and. In the remaning year, which was the only really

stopped short of the 80th degree uf latitude, there need be no question of that
p«n«llel being accessible ; for, it U a general &et, in re^WCt to tbe conforma-

86 Rev W. Scoresby's Remarks on the ProbabUi^
'* the;nature of the ictf was b^ond all comparison xhn most un-
favourable for their purpose that he ever remembered to have
seen.^ In fact, Captain Parry never reached Utejaat-ice, though
he was evidently near either it or some exten^ve land, as proved
beyond any doubt by the yellow-ice blink that was seen to the
northward of them, when they found it necessary to return. And
it appeara not improbable, from the experience which this trial
gives, that there is land not only to the eastward, but also to the
north-eastward of the Seven Islands*, from the proximity of
which the ice had been raised into such formidalile hummocks,
and broken into such small masses. For, on Bom£ meridians,
and no doubt to the westward of Hakluyt's Headland, we know
that there always is a vast body of field-ice, from the carcum-
stance of that kind of ice being frequently traced, in one conti-
nuous chain, from the 80th to the T'lth degree of latitude, or
indeed as far to the southward as the whalers have penetrated.
And that there is abundance of the sane to the northward of the
80tb parallel, is certain, from the circumstance of the constant
south-westerly set, during the summH-, of the whole body of ice
between Spitzbergen and Greenland, aad the constant succession
of other fields descending from the north or north-east to sup-
ply its placef . And it is ice of this nature, to a great extent at
least, that we should have good reason to calculate on meeting
with, and uptm this, the journey to the pde with rein-deer, or
other traineaux, might, in reasonable probability, be accom-
plished ; notwithstanding the broken, rugged, and unfavouraUe '
nature of the ice met with by Captain Parry, owing to which,
among other causes already stated, hts rein-deer were rendered
useless, and so little success was attained.
That the kind of ice across which Captain Parry travelled,
was something peculiar to the meridian whereiu his progress
' Captain Pnrry saw land to tbe eastward of the Seven lalanda ; and in
fome of the old Dutch charts there is an extenilTe tract mailed out stUl &r-
tfaer lu the northward, and designated hy the name of "^ Purchas' Land," or
" Purchas'o Point," or " Gites's Land."
-|- Tbe proo& of these &cts being given, both in the paper on the " Polar
Ice," (Wemeriati Mcqioira, vol. il. pp. 309, 3IB}, which I had the honour of
submilUng to the Society, and also In the " Account of the Arctic lUgions,"

was made, appears certain from this fact, that, in the whole
course of my experience among the Arctic ices, during which I
probably traversed among not less than twenty thousand leagues
of ice, I never met with any ice, except icebergs about the ribore,
at all resembling the scene represented m Captain Parry's Nar-
rative, in the plate entitled *' Travellii^ among hummocka of
ice." These hummocks, in proportion to the men, appear lobe
from thirty to fifty feet high, or upwards, whereas the ordinary
hummocks of the heaviest field-ice that occur in ridges or groups,
seldom exceed twenty or thirty feet high, and hummocks of forty
feet are not of usual occurrence, though an insulated peak of
that height may be seen oc^Wonally. Besides, the want of field-
ice WHS of itself a decisive proof of an unfavourable situation.
The largest floe that Captun Parry fell in with was only two
and lubalf or three miles square,— the only occasion in which
' they saw any thing answering, in the sUghtest degree, to Uie de-
scription given of the " main ice ," yet no fields were met with •.
Whereas, as I have already shewn, field-ice, to the westward of
Spitsbergen, has often been traced, in acontinuous chain, through'
an extent of ax to ten degrees of latitude. In respect to the
extent of the diflerent masses, I may remark, that whereas the
greater proportion of ihe ice may consiBt of floes of various mag-
nitudes, a very considerable quantity is often found of the na-
ture of fields, that is, of such large dimensions, that an observer
from a ship's mast-head cannot overlook them. And, in regard
to the nature of the surface of these floes and fields, 1 may add,
that, although the greater number, perhaps, may exhibit a hum-
mocky appearance, fields and floes, containing an even surface,
for an extent of miles together, are quite common.
Having, for some years, been in the habit of observing the na^
ture of the Arctic ice in reference to the practicaWlity of a jour-
ney to the Pole, I find, on reviewing my journals, several re-
marks expressly on the subject. Thus, in my manuscript jour-
nal for 1820, I find mention of a field remarkable for its size.
We sailed along its solid continuous edge N. N£. 12 miles ; N.
4 miles; and N. NW. 8 miles; and were yet far from it^ north-
ern extremity. It was calculated to be 150 miles in circumfe-
rence. I was led to this remarkable sheet of ice by the " blink,"^

Htm ^th 6f July, it is stated in my journal, that,- " with a gentle
breeze of wind from (he southward, we traced the edge of a sin^
gle field towards the north, from 9 a. m. till ^ v. h., which
«as estimated to be thirty geographical miles in medial breadth.

ticid, on the same voyage, we coasted & distance of abeut forty
miles. And again, under date of the 16th of July, (latitude
70° 49, longitude 19" 44' W. ), I find it recarded, that " we pas-
sed, in our progress through the floes, some remarkably fine
anoo^ sheets of ice. On Severai of the heaviest floe^ av«-^-
ing, prohaMy, twenty feet in thickness, there were occasioaiil
tracts of above a mile square on which there was not a dn^
hunftoodE. And oi>e field had a ^>ace of about twenty-four
square miles, (four miles by six by estimation), equally regular
and even." This fidd, indeed, was so stnootb, that I designed,
had we remained nax it a suflicient time, to have made trial cf
• sailiatg-dedge, respecUi^ which I had given iny cArpenter ot'
dets ; and I had no doubt of being able to (raver^ h by the
mere force of A moderate breeze of wind.
From these facta and observations, I think it nnist be quite
evident, that the nature of the ice met with, in the rec«it expe-
rmient, must Have been (£fierent from what it is os a more wes-
terly meridiaD ; and that this circumstance of itself prevented a
fair chance of success. I shall not differ, bowev»', in my views,
from Captain Parry, as to whether it may prove to be *' an easy
task" to traverse the ice to the Pole. I know it would ruri be an easy
ta*k, and that it would not be found exempt from its peculiar
haeards ; but I still believe, from all we yet know 6f the polor
ices, and from all the experience yet obtained, that flie prdttt^-
li^ of reaching the Pole, notwithstanding the recent fwlure, re-
mains unshaken, and that it is a project as feo^ble, and wen
much more so, than the discovery of a north-wesl pieAage d^
aed, and some other approved enterprises.
To what has beeil already sud ill support of this ccmdnnon,
I m&y add one general ai^metlt, whidi will go fkt, I conceive
to support th^ whole <^ the grounds of reasoning which I had

UarkoS^ accordiog to MOUer, with eight other per^xis, start-
ing flroca tbe mouth of tbe river Jana, in the apring of the year
1710, peif(»med a direct distance across the ice to the north-
vard of 300 or 100 miles, (300 miles accocding to C^>tun Krt>-
•ensteni), in light sledges drawn by dogs. Lachoff, a merchant
of Jakutsk, with a un^ ocHnpanioD, went, in the beginning of
April 1770, from the Swsetm Noss, above IQO miles to the
■torthward upon tbe icc^ by the same mode of conveyance; and
eariy in Af ay of tbe year 1775, the same adventnrous person
proceeded to Kettle Island and along shore, a distance, as mea-
sured ufOD, the beat charts, of at le^at 240 geographical milea.
The manner of Sanniskc^s travellii^, when he proceeded, on
tVQ or more occatitHis, 70 (h* 80 leagues to the northward of the
coast of Siberia, I have not been able to ascertain ; but I pre-
■ume it was in sledges acrosa tbe ice. Hedenstrom, however,
who was sent out for research ipto the Icy Sea, by tbe enter-
prizing and bb^vl Bomauaoff, made difier^tf extensive journeys
from the entrance of the Jana to the coasts of New Siberia. In
his fir^ expedition, which was commenced in the month of May
1809, 1 do not £nd in what way he made his progress ; but, in
a subsequent expedition, in which he iq^>ears to have advanced
about three degrees directly north, beades researches upon the
eoast of New Siberia, there can be no' doaht but that hia mode of
{iroeeeding was in sledges, as the adv^ture was accomplished
in the winter season. And Baron Wrangel, who still more re-
cently p^ietrated tbe Fplar Sea frofa Skalatskoi No^, travelled
acroaa the ioe about 80 imles dinetly towards tbe north.
Now, it is worthy of remark, that all diese journeys aCKiae the

After such great success in similar enterprises by foreigners,
it becomes a natural inquiry, why our adventurers, with all tbe
advaDtages and admirable arrangtanents which tbe talent and
■ liberality of the British Government could alTord, ^accomplished
80 little P Why the different travellers alluded to accomplished
a direct distance across the ice, one of 80 miles, another of 100,
and afterwards of S40 miles ; another more than once of 70 or
80 leagues, and another of between SOO and 400 mites, whilst
our expedition completed only, ttpon the ice, a direct route of
7S miles P When most of the above adventurers accomplished
mam/ leagues a-day on ice, travelling without difliculty, why
was it that our expedition, assisted by all that natural ardour so
peculiar to Briti^ seamen, could seldom complete more than
four or five miles a-day, directly across the ice (independ«it of
currents), and smnedmes, after the most laboriouB enertions,
why were they able to advance oa\y two or three nules within the
twenty-four hoursf ? Surely it was not that our adventurers
were less capable, less hardy, less enierprizing than others P To
suppose it, would be to prove myself ignorant of tbe exertions
that were made, unjust to the merits of the travellers, or preju-
diced against an expedition that has &iled of success. But there
' Th« authorities from which these particulars, reipecting jouTneys across
the ice, were derived, are MUller'a " Tayages," Coz'a " Russian Discove-

Captiun Parry, with whom I have the honour of being ac-

especially as there was no possibility of vindicating the plan ori-
ginally submitted to the Werneriaii Society, for approaching
the PtAe, without comparing it with the plan of the regent expe-
dition. And I regret that these remarks have assumed (unin-
tentionally and unavoidably indeed) the appearance of a.criti^
cism on Captain Parry''a attempt ; but it must be obvious to
any one, that the object of this paper could not have been sufB-
oently accomplished without it. And that I ought, with the
views I still hold of the practicability of the pn^ect, to attempt
its vindication, 1 trust the introductory remarks to this paper,
which were written some months ago, will justify ; for it might
naturally be said, that I considered ihe project of reaching the
Pole, by a trans^acial journey, as feasable, and proposed a plan
fot carrying it into effect ; but as Captain Parry has attempted
the project, and, on a plan in many respects umilar, has failed,
it must therefore be inferred that the undertaking is not prac-
ticable. Hence I am driven to the necessity, if I speak at all
in my own vindication, of criticising the defects of the plan of
the late expedition. And that I refer onhf to the plan, 1 con-
ceive it justice to my own feelings, as well as to the persevering
adventurers, explicitly to state ; for I give full praise to the great

TaMesJbr Barometric Measurement. By Mr William Gai^
BXAiTH, A. M. (Communicated by (he Author.)
SIR, Edinburgh, 3d April 18S8.
JM.Y attention has lately been directed to draw up and collect
a commodious set of tables for the barometric measurement of
altitudes, as well as for the ordinary purposes of reducing the
oButd observations with the barometer. I need not inform
you how rudely these are frequently made with the common
barometer. This arises both from a bad state of the instruments
^nployed, and the inadequacy of the correctjons generally
applied to reduce them to a standard point of temperature and
level.
The accompanying tables, from winch the necessary correc-
tions, in all ordinary cases, may be taken out by inspection, are
intoided partly to remedy this inconvenience ; and if you think
than worth attention, perhaps you may give them a place in
your useful and extensively rarculated journal, so that they may
be more generally known. I have carefully computed the first
table from a formula of our distinguished countryman, Mr
Ivory ; and, of course, I have no other merit than the labour
of computation. This I have executed for tu^s varying in
ffiameter from one-tenth of an inch to seven-tenths, to every
hundredth of an inch, thereby including every variety of bore
likely to be used. The second is merely an abridgment of tate
given by Schumacher in his Hulfstafeln. The ap^ication dF
those two will therefore give the absolute h«ght of the mercury
in the barometer reduced to the freezing pcnnt.

A Short Sketch of the GetAogy ofNithidale, chiefly in an Eco-
nomical Povntof Viae, and contrasted with that of the Neigft-
bouring ValUys. By Jahks Stewakt Menteatii, Seq.
Younger of Closeburn, Member of the Werneriaii Natural
History Society. (Concluded from page SSS of last Number).
X HE strata of the limeworke at Closebum, are divided by the
workmen into upper and lower posts ; and, in considering them,
it may not be improper to reCun these names.
The upper post of limestone is 14 feel thick, being contained
between two impure strata of limestuie, called by the workmm
dogger. The lower post is about 18 feet thick. The upper
post, with strata of sandstone and clay, overlies the lower post.
Both these two posts of limestone seem, from appearances, to
extend from the present workings of Closebum across the
southern raid of the Basin of Closebum to Barjarg, on the
west side of the Nith. But the uniformity of their continued
inctination is interrupted by a throw-down of dislocatitxi of the
strata. This is to be observed at the New Kiln, situated at the
south-west of the present fr<»kinga.
In consequence of the great expence of removing the cover
from the upper post of limestone, and likewise from a quantity
of magne^a which it ccmtains, little of this post is used. About
forty years ago, specimens of this, and of the lower post, were
analysed by the late celebrated Dr Black of Edinburgh ; but
from the imperfect method of analyns then known, the presence
of magneua was not detected in the upper post. But when this
upper post was analysed a few years ago by the late ingenious
Dr Murray, it was found to contain in 100 parts, 43 parts <^
carbonate of magnesia, and 54 of carbonate of Ume. When it
is calaned, it makes an excellent cement.
Occasionally in this upper post cavities are observed, and axe
often found filled with the black oxide of manganese.
The lower post is nearly 18 feet below the upper, and sepa-
rated from it by strata of sandstone and clay, having, however,
the same dip as the upper. It is about 18 feet thick, and is
the pure carbonate of lime, ascertained by Br Murray's analysis
to con»st in 100 parts of 91 of carbonate (^ lime, equivalott

to 50 of pure lime. In this lower post, are several small beds
of clay or stmie marl, containing )0 per cent, of carbonate of
lime, withimpresdonBof shells, and alternating widi beds of lime-
stone, which have imbedded in them some very interesting organic
remiuns, several of which have been drawn and dest^bed by
Sowerby in his Mineral Conchology. The fallowing are the
most curious :— Orthocerte, nautili, some sjnrai shells, prtv
dueti, tnlobites, and corals. The knowledge of eu^ peUi-
faetions has become more interesting, nnce H has been aecer-
tuned by Mr Smith, the ingenious author of a Mioendo^ca)
Itbip of England, that ihey may be often a meam of identifying
■tiata. Advantage has be^i taken <^ these clay-beds to mine
the lower post of hmestone. For some yeta^ the operationa ef
this mining have been exlensively carried on, and these exeavft-
tioBS now exceed many hundred square yards. In proceedir^
■Mhlbese exoavations, strong pilars of nearly 6 square yatds in

upon an incliBed frfane, up which, to the tag of the kiln, Ute

has been for aeveral yeare adopted at Closebum Lime Quarry.
The gnaat. advantage of a connnand of water in carrying on

guch a form of Jciln that will <produoe in a g^ven time the great-
est quantity of veil calcined lime, with the smallest possible
quantity of fuel.
The kilns employed at Closeburo Works are built on the side
of a hill, and they are of two forms, die circular and the oval.
The drciilar kiln has cast-iron doors to the fuel chamber utA
ashpit, and a cast-ir^n capor cover, which, turning on a pivot,
raid Testing on a curb-ring fixed on the Xaip of the masoury of
the kiln, can be put tn or off the top of the kiln when requmd.
This iron cover, having a chimney 19 inches in diameter, fitted
up 'with a damper, prevents the escape dS heat at i^ times ; and
wbea the xountiy sale is irc^ulac, kcep^ die fire from gwog out,
by-beng'kept close, as well as the doors below. One of thcM
cinuW irpD-topped-kilns will deliver daily, of well calcined -lime,
fths of its contents.*
Closebum lime-work receiving its fuel from a gwat distanee,
ft6 'miles or more, it is found to be a considerable saving of oar*
riage to-eoke or char the coal at the pit. A measure of tMs
C4^e burns as much as the same measure of -coal, b»t ts used
only in thb kind of kiln.
The- ovfil kiln varies somewhat in its proportioos &om'tbe c^-

cireukr. It has windows to the fuel i^iamber, and ash-pit aiiid

(liuly ; and when it is closed at top and bottom, the Sre will not
go out for five or six days.
The lime-quarry at Barjarg, on the other side of the Nith,
is worked, not by mining, but by removing the cover from the
rock ; and is of course done at more expence. The kilns are
here of the common kind, without iron-covers or iron-doors for
the grates. The lime-quarry at Closebum has been opened
and worked for above fifty years.
It is curious to observe bow much prejudice often opposes
useful improvements. When these limeworks were op«ied in
1773, sageneral was the opinion of the injurious consequences of
Ume laid on land for agricultural purposes, that the proprietor,
in order to introduce its use, obliged his tenants, in their leases,
to lime a certain quantity of land yearly, he furnishing the Ume,
and even paying for the carriage ; and the tenants on their
parts, were bound to pay 5a. addidonal rent for every 80 mea-
sures of lime, the quantity considered sufficient for an acre.
Kotwithstanding, however, this liberal encouragement to the
tenant, the greatest quantity of ground he would be induced to
lipe, was only two acres in the year; and some could hardly
be prevailed on at all to make the experiment. But experience
has surmounted this prejudice, and no inducement is any longer
required. Its effects on the appearance of the country are most
striking. When Uie present proprietor of Closebum came into
possesfaon little more than SO years ago, the country around
* these lime-works, to a considerable distance, was covered with
heath, barren, and unproductive. By judiciously, however, ap-
plying lime as a top-dresang, the heather has gradually disap-
peared, and has been replaced by good herbage. The effects of
this lime-quarry, and that of Barjarg, tnay be seen all over the
Bafln <X Closebum, and io the adjoining Bafdns of Sanquhar,
Glencfurn, and Dumfries ; and even much farther, as into some
parts of Galloway, distant 40 miles from these works, for in
n«tber of the districts of Galloway has lime hitherto been
found.
Not far distant from Closebum lime-works, on the same side
of the Nith, are two small barans of limestone, which appear
unconnected with it. That which is found at the Shielgreen is
interesting, as it presents a vitrified appearance. It is not a
pure limestone, but contains a portion of sand. The other

occurs at the Linbuni ; and though also very impure, differs
from that of the Shielgreen.
The soil of the batdn of Cloaehurn varies very much, par-
uking somewhat of the character of the strata which it covers.
The soil nearest to the greywacke is clayey and tenacious, re-
quiring much drainage, and much lime. Its improvement, after
these operations, is rapid and astonishing. Much of the inte^
rior of the surface of the ba^n is thrown up into small ri^ngs
(H* eminences, and the soil of all these is invariably of a water-
worn, rounded, pebbly gravel. This kind of schI requires no
little expcnce and exertion to render it productive. But the nu-
merous hollows intervening between these gravelly hillocks, are
frequently filled with peat-moss, of which tfac industrious hus-
bandman has availed himself, in many instances, to make into
compost with lime, and strew over Jhose gravelly grounds.
And by these means, and by cultivating the turnip, and feed-
ing them off with sheep, he is enabled to reap heavy crc^ of
grain from these light gravelly tracts of this basin.
There is a narrow tract of soil, thou^ pt^ty extensive, moor-
ish, and filled with white round pebbly stones, which is the
very worst of all tlie soils in the basin of.CIoseburn, and is with
great difficulty rendered productive.
There is a considerable extent of land in this basin covered
pretty de^ly with peat. In reclaming this soil cm the estate
of Closebum, the improvements have been attended with the
most gratifying success. A variety of grasses have been culti-
vated on these peat soils, but non have succeeded so well as the
Holata lonahis, or soft grass, or Yorkshire fog. Its seeds
being produced in immwse quantities, can be procured at a
cheap rate. The peat land in the course of cultivation is gene-
rally found to be too little tenacious, and is apt, if sown with
grtun crops, to injure much the succeeding grass. In these im-
provements on the estate of Ck>sebum, all grain cultivation has
therefore been moat carefully avoided. As soon as the peat-soil
is prepared by pi»per pulverization, by ploughing and harrow-
ing, it is then sown with the Holcus lanattu, whose innumerable
mots and far-spreading leaves, soon cover over and restorea
tenacity to the soil. With this grass the clover grows admi-
rably well.

All the varietieB of soil, bowever, of the doseburn basin uc
improved by lime ; and whenever lai^er doeee of it are laid oa
the s«m1, and a better Byatem of husbandry generally pursued,
very great improvementB may be expected in the g^ieral aspect
of the whole surface of the district.
It may be worth while, as connected with the subject of sinl,
to mention some curious facts respecting the growth, toughnesi,
and durability of different kinds of wood in the basin of Cknc'-
bum, and which may perhaps be looked for in other districts ttf
Scotland similarly circumstanced.
The Scotch fir, Pmus sylveatris, thrives well, but does not
grow fast <m the soil over the sandstone. 1\& wood, however, is
lough and very durable. But when this same tree is planted
on the greywacke, though it grows more rapidly, and arrives
sooner at maturity, yet being softer and fuller of white wood
than that grown upon the sandstone, the builder, to his cost,
finds that it is soon attacked by the worm, and decays*.
The reverse of this ha[^ns with the Larch, I^nui Larur,
when growing on the greywacke. Its wood is sound and good,
and, when cut down, is at heart quite perfect. But on the sand^
Stones and gravels of this basin, it seems to be at maturity at an
earlier age than that growing on the greywacke, and, in many
instances, when cut down on these soils, the larch presents a
tubed, decayed heart. Under twenty years old such instances
of internal decay appear. And the remarkable thing is, that
externally to the eye the larch seems healthy and vigorous.
We may here state that the larch grows naturally only on the
primitive mountains, as the granite, gneiss, and the like rocks of
■ Some remukiible facts respecting the durabilitj that may be given to
timber bj artificial means, Lave been observed at Closeburn. The proprie-
tor of that estate has for thirty years been in the constant practice of soaking
alt fir wid larch timber, after H is wired into ^juik, in a pond or cistern of
vat«r, strongly iiapr^nated with Uioe. In coosequenoe cf this SDaJdng, thiB
MGcharine matter in the wood, od which the votm is believed to live, ia luther

tkat (daas of Uw Alps, in SiriUerUnd. And it ia most curious
to obaerfe, that, on the whole range of the Jura mountuns, te-
{Miatiiig thkt couBtiy from France, and being a limestone for-
natim, rising to an elevation of several thousand feet, not a
n^le sd£«owR larch can be discovered.
AdvsncBBg, however, from this range into Switzerland, it may
b« observed, that, ui those places, as at Chamounie, Mount Ce-
nis, the Simpion, and the lofty Alps, which partly inclose the
baaubful ]ake of Thun, in the canton of Berne, wha^ the
pnmitive formation, consisting of granite, gnems, mica-slate, and
similar rocks, abounds, the larch is indigenous, growing luxuri.
antly, and attaining to a g^at size. Almost at the summit of
the Simpkxi, upwards of 6000 feet of elevation above the sea*
instances are met with of larches of \6 feet in circumference at
■omB distance from the ground.
Connected with the same formation, are the largest larches
found in Scotland, as at Dunkeld. One of the largest of these
trace measures 18 feet in circumference ; and they iu« of no
g^eat age, for it was only in 1738 that they were brou^t from
the Alps, and planted at Dunkeld. From the prc^;ress they
lutve made, and their present thriving appeenuice, it is proba-
ble they will attain a great age.
The durability of the larch tbrou^out Switzerland is prover-
bia) ; and in all situations where exposure to weather must be
encountered, such as roofing of houses and the like, veoourse is
always had to lart^. It is said that the piles on whiicJt Venice
ia built are of larch wood. It would thus a|^iu-, that the
greywacke approaefaii^ very near in qualities to the pnmitive
mountain soil, is the best qualified to grow the larch ; and in
Nltixdal* the larch ought only to he planted on the ^eywacke,
as is evidently proved by experience in the Basui of Closebum.
While enumerating the mineral productions of this basin, we
must not tc^get to mention its mineral flings, although theae
an neither Dumerous nor important. In some places, chidy-
btate waters are ^JM^d, and have been used, to oon«derable
advantage. Near the Castle of Closebum, issuing from a peat-
moss, now improved, is a sulphuretted hydrogen spring, and
another at no greM distance, which have sometimes been rraort-
ed to with good effect in cutaneous complaints.

Si Mr Menteath on the Geology ^XUhadale.
. Baain of Dumfries. — The Basin of DumfrieB, the last of
those that form Nithadale, is separated from that of Closebum,
by a considerable ridge of grey wacke, aearly five miles in breaddi.
Through this ridge the Nith finds itself a passage, and enters
the Basin of Dumfries. This Basin is (^>en on the south, and
is there bounded by the Solway Frith ; but on the east, nortli,
and west, is encircled by the grey wacke, except at the south-east,
near Mousewald Kirk, where it unites itself to Annaiidale.
The greywacke hills, which partly surround the Basin of
Duipfries on the east, north, and west, are of lower eleyadon than
those of Closebum, and of much less pleasing forms. They are
green, and cultivUed to their summits; but produce fewer
streams than the three preceding Basins. Of these, the only mk
of any note falling into the Nith below Lincluden Abbey is the
Cluden. In its loog, pleasing, and winding course, it passes
through the parish of Glencaim, a pretty wooded sequestered
baan. The whole of it, as well as its encircling mountains, are
greywacke, separaUng it from those of New Cumnock, Sanquhar,
and Closebum.^ The Lochar, a detached and independent
stream, in its way to join the Solway at Carlaverock, passes
through an extenuve peaUmoss,* which, by its broken, black,
swampy appearance, casts a gloom on all the beautiful scenery
ot the lower part of the Ba^n of Dumfries.
The interi<M- of the ba«n of Dumfries is filled entirely with
the New red sandstone, for as yet no traces of the white or grey
have been observed. This red sandstone is much softer, and
decays more rapidly by exposure to the weather than that of
Closeburn. At Lochar Bridge, and at Castle Dyke quarries,
when this red sandstone is raised, proofs may be seen of its de-
composing nature f. On the west side of the Nitli in Gallow-
way, to-the south of Griffel, which is aenite, near Arbigland, the
coal formation appears ; but the strata are so much on thdr
edge, and so inagnificant in their thidiness, that they are of no
value. It is very probable that the Solway Firth is a great coal
basin, for coal is worked on the English sid^, as between Work-
* In it oftcD are found the bones and faonu of s ta:^ fipedes of deer.
t At the latter place, the miueralagiat will find imbedded in the red Mud-
stone, curious Bpecimeiu of basalt, and other rocks of that kind, tome of Uwm
exceeding the «ize of a man's head.

. ingitoii and Whitdiaven ; and on the Sooted ode the strata of
the coal formation (coal metals) shew themselTee.
No litnestone has been discovered in the basin of Dumfriei.
A litUe beyond its south-eastern extremity, aa at CamlcngaB,
the limestone appears, but coarse and bad in quality. The
farther, however, we penetrate into Annandale, in its lower dis>
trict, it becomes better and more abunduit.
Of the ores, no traces have hitherto been met with in the
baan of Dumfries.
Here, as in the valiey of Closebum, the greywacke decays
into a sinl which is a cold and stiff clay, r^uiring lime to loosm,
pulverise, and fit it for the growth of herbage. Not much,
however, of this kind of soil occurs in this basin, for the greater
part of it resting on the red sandstone, partakes of those quali-
ties that are usually observed in red sandstone districts. The
ami is generally light and gravelly. It requires much manure
atid good husbandry to make such a soil productive. On the
western slope of the Tinwald greywacke hills, the soil is ridi,
deep, and loamy, and may perhaps be conudered the best tract
of soil in the baan of Dumlries.
It is a great hindrance to the more improved cidtivation of
the basin of Dumfries, that no limestone has been found in it ;
all that is required for agricultural and building purposes being
either imported from Cumberland, or brought from Closeburn
or Baijarg liweworks, or Kellhead, in Annandale.
Thus we have pointed out a few of the most striking minera-
logical appearances, including those of soil, in the four bauns of
Nithsdale, and we have found that each has some peculiarity.
The bann of New Cumnock, abounding in coal and limestone,
though at a conaderable elevation, and with a strong, cold, ad-
hesive clay bcmI, is cultivated almost to the summits of the hills,
and inbatated by an industrious, active peculation, who have
availed themselves of their natural advant^es, and have turned
their attention and capital to collect large dairies, which yield
them ample retiuns in butter and cheese. It cannot be doubted
that these improvements have, in a great measure, resulted from,
and been fostered by, the abundance and cheapness of Hme, in
which this basin abounds. While, on the other hand, the San-

and Baijarg, an ample deposit of excellent Htnestoite, has made
rapid strides in the improvement of its soil, and tmist and wfU
proceed much farther. Many and most striking evidenoes on
the eEtate of ClosebttMi are before the eye, of the astoiri^ing
and cheering alterations which lime, laid on to great quantiitMSf
makes on the face of a heathery and barren tract of country.
Even the bamn of Dumfries, deprived of either coal or &De-
Hone, has, by good communications by land, and by improve-
ments in its river navigation, been enabled to remedy, in some
degree, its want of a limestone depotut ; and will not be outdme
by the natural advantages of the three higher basins of tbe Nith.
It may not here be nnworthy of remark, and may appear not
a little extraordinary, that, in ntuations so similar as the b^ns
of New Cumnock, Sanquhar, and CtoBebum, we find coal and
litne in abundance in one, coal only in another, and lime aloae
in a third. What process could be going on in these diffeitint
basins, so as to a^rd this difference of products, geology has
not yet perhaps advanced sufficiently far to enable us to attempt
any satisfactory explanation.
Having now, as far as we have been able, given an acoaUQt
of a few of the remarkaUe geological ^pearancts of the fbur
basinsd' the Nith, or of Nithsdale, it may not be uninteresting
to take a hasty glanoe of the other two districts into which

dole, in order that we may be able to draw a comparative view
of (he natural advantages of the three great districts of this
county.
Banimofthe Annan. — The first of these, AnitondaJ^, maybe
divided into the Upper and Lower Basins. The Upper is d^>a-

MKk, which irons across thd Annaa at the Maine of 8t Mungo,
uniting the 'Hnwald greywacke range of lulls with those on the
eastern banlT of the Annan, and may be traced skirting the
greywacke mountains from Burnswark to Lan^iolm. This took
seems to Cut off the new red suidstone of Uie Upper and Lower
Basins ; but as it has been bored in seraal jJaces, and the
red sandstone always found under it, we may infer that the red
sandstone extends from the one basin to the other, and is mere-
ly covered by this formation, or probably the amygdaloid inter-
sects the sandstone.
The greywacke moimtains whidi shut in this upper bnun of
the Annan are lofty, aod to the ninth present a Md [ucturesque
oudine. Their ndes slope to the Annan, and afford good pas-
turage to numerous flocks of sheep. In this upper basin, the
wood, from something unfavourable in the soil, is scanty, and
does not appear to grow luxuriantly. About Baehills, the
qjruoe fir is that which grows best. On the west, the Annan is
. jmned by the streams of Evan, Ae, and Einnel ; on the east, by
the Moffat, Whamphry, Dryfe, and the Milk, all proving, by
the number of the streams issuing from these mountains, their
great elevation.
The interifv erf* this upper baain <j( the Annan is filled with
the new red sandstone^ This red sandstone is well fitted, from
Its compact texture, for all icinds of building.
Neither limestone mn* ores of any kind have hitherto been
met with.
A mile froia the town of Moffat, resorted to for its medicinal
waters, there is a sulphuretted hydrogen spring, issuing from a
gi^wadie rock, craitaining iron pyrites, and passing through
a peit4x^, where it is probably still more impregnated with
aulfriiur.
Ab(Hit five miles ftt>m Moffat is Hartfell Spa, which is a
strong dudybeate. It issues irom a rock of alum-slate on the
side of the mountaia of Hartfell.
These ^rings have caused great resort to this district, and
have thus as it were created the intwesting village of Moffat,
and contributed to the improvement of the neighbouring coun-
tiy.
The soil of this upper haain of the Annan, consists in part of a

stiff, teoacious day, which may be probably owing to the num-
ber of streams constantly wearing away the greywackc mouB- _
tune, and carrying their debris into the basin. 'The seal on
some of the more level parts, as on the banks of the Annan, is a
-fine rich alluvial loam, productive of all kinds of grain.
To the south of the Manse of St Mungo, the lower basin of
the Annan commences, and expands itself a considerate way
towards the Solway Firth. On the west it unites itself to the
Jtaaln of Dumfries ; and to the east, to the lower basin of the
£sk. The Milk and the Mein are the prindpal streams that
join the Annan in its course southwards.
The sandstone which prevails is the new red, which appears
nearly to cover oil the other strata, except in some places, as at
Cove Quarry, on the banks of the Kirtle, where the Ught ochry
sandstone bursts up from under it. At Kilhead, the limestone,
being in some places overlaid by an impure limestone, c^ 30 feet
thick, and upwards, Is quarried and burned. Its thickncsH is
about 30 feet, and it is s^d to yield 95 parts out of 1 00, of car-
bonate of lime,
From.sev4H«l appearances of the strata, where sections con be
hod (as in several places of the Kirtle, a beautiful wooded stream,
which flows into the Solway, m(n% to the south than the Annan),
indicating strongly the presence of coal, it is probable that that
valuable mineral may be discovered ; but whether in beds cf suf-
ficient thickness to repay ^e expencc of working, cannot be as-
certained till farther triob be made ; and, indeed, from iate at^
tempts that have been undertaken in this quarter, it seems very
doubtful *,
The s(h1 of this lower basin aS tlie Annan partakes very much
of the characters of that usually occurring in coal districts. It
is a stiff, adhesive clay ; has great tendency, from its retentive-
nesa of moisture, to produce the rush ; but, as this basin abounds
in limestone, die means are at band to obviate some iA the de-
fects of a clay soil.
Baain of the Eak. — The river Esk, in iu course from its
source to the Solway Frith, flows throu|^ two basins, an upper
and a lower. It is difficult to distinguish the lower basin of the
Esk from that of the Annan. They run so much into one an-

otfaer, tbat a, bettef divigton of tlus lower distnct of Dumfneu
shire would be, to consider the two as one large bftsin. The
mouDtainfl which form the odes <£ the hig^wr puts of Eskdale
are high, having e&UHNTe graasy elopes, that yield to large flocks
of sheep an excelleot pasturage. Fnxn its source to LangfairfDi,
i\M Esk, joined by the Meggot and the Kwes, nins in a very
straitened beun, which may be called the U{^r Basin of the
Eek. This basin costtuns neither coal, lime, nor sandstoiie
throughout its whole extent, the prevuling rock being gr^-
wacke. At Glradinning, the grey wacke rock ocmtains grey anH-
monff-g^Ke, or aulplmret of antimony. Some years ago it was
mined to advantage, but the workings are now obandraied. In
tbe saoie neighbourhood, aoKHig the mountains, there are traces
otgi^ma or iead-glatux.
Below Lon^KJm, the basin of the Esk expands ; and, (o the
west, unites itself with the Ixiwer Budn of the Awian, wtadi
may be called the I^iwer Basin of the £sk. This baMn contaios
iDOUDtaio limestone, the coal ftmnation, and the new redsan^
stone. These deports, according to Professor Jameson, are ar-
ranged in tbe usual order, the mountain limesttme being the
lowest ; next the coal ; and, resting upon the coal, in several
places, the new red sandstone. On the Byrebum, below Lang-
bdm, the cool is wwked, tbou^ no seam exceeding 3 feet has
heai discovevd.
From Langholm, in the directicHi of Ecdefechan and Brown-
muir, limesttme is found in all that range ; and beyond, to the
north of this line, the greywacke.
The sml of the lower baton of the Esk is similar, in all Its cha>
racter and qualities, to that of the lower basin of the Annan.
Having thus hastily and ra[»dly sketched the districts of An- '
nandale and Eskdale, and, as briefly as ve could, enumerated
ibeir mineral deposits, it may not be uninteresdng to contrast
them with Nithsdale, whit^ forms the principal sul^ect o( this
^etch.
In the upper basin of the Annan, we have observed that there
is neither coal nor lime ; that its distance from those districts
wbtte these minerals abound, has checked its advancement in
improv^ement. The upper baun of the Esk, without coal, lime>
stone, or sandstone, is still more unfavourably situated than that

c^ toncioiu cU^s that cover so large a tract of these basins,
will be nlutnatelj improved and rendered mucb more produc-
tm, wbm greater quantities of lime are employed in agriculture.
Although tbe uj^r basiDs of the Esk and the Annan are
behind those of the Nitfa in mineral treasures, and in improve-
ments, yet, if the local advantages of wat«-, every where so abun-
dant in these two distriots, were embraced, it may be presumed
that tbe want of limestone might, in some degree, be compen-
sated : For these two basins, shut in on all ^des by lofty grey-
wm^ ibauntains, (dxHind in streams which oSer great fa<^tiea

mmius 6ooks fed in these districts, which are often, in the se<
vsre Btorms oS winter, and in the dry coU springs, driven to
great extremities for food, would be abundantly supported ; and
h is probable that, by these means, the stock might be greatly
increased. Tbe ejKciency and successful application of water in
flooding meadow or low lands, and thereby augmenting their an-
nual produce in either grass or hay, has beeu cleariy d«Qon-
strated by what has been done on the Closebum estate in Niths-
dale *. Its proprietor, sensiUe of tbe infinite value of water for
meadow lands, has, at much cost, engineered a water-course of
■eitai miles in length from the greywacke hills cm tbe east of the
basin of Closebum ; and, in another direction, another course of
equal length, which collects, in their passage, every rivulet that
dMcende from tbe hills. These two canals are made to irrigate
&n tttteflsive trtCt, producing a large increase of food, often up-

as these gttJUnds formerly yielded. These successful applica^

the Ma, and mi^ therefore be Happosed not to differ mich fti
eUmate ; and the am] ig, we bdieve, not infenor.
But when we oompare the two i^stiicts with csdi other, we
find « itriking difitr«nce. Nithadale, as we have seen, hoB abun-
daooe at Hmestone, coal, and tandatone, eitending almost to the
source of the Nith, adoiittiDg of houses beiog built wril soA
cheaply, fuel being had at a trifling espence, and the land cul-
tivated almoBt to the tops of the hills. But in the Valley of the
Dee, in Kiritcudbrightshire, there is neither coal, lime, nor aand-
atotie; and We flttd hi that trut, nearly the whole upper part of
it, almost waste. No village occurs ei:ceed>t^ a few houses, and
these indifFerenlly built ; the land, from want of lime, is uncnl-
tivated, and laid out mostly in extensive sheep farms; and there
. is litde hay except what is naturally produced for rearing of cat-
tle,— «n evil which might probably be, in some degree, reme-
died by the use of irrigation, as already suggested in regard to
the upper districts of DumfKesshire. There are, however, none
of those mineral substances which pve employment, and create
s population to consume the produce of the sraJ, and promote
the industry of the farmer.
Thus are these two districts in Galloway and Dumfriesshire,
in several respects, similar as to situation, soil, climate, and ex-
tent, but widely (Ufi^rent in improvement and population ; and
this difference arises chiefly fi'om the superiority rf the one over
the other In mineral treasures. Nor is it to be thought that
Nithsdale has, from its minerals, yet derived all the advantages
of wMch it is «tpable.

discovery <^ useful mineral substances, we may expect that this
tract will furnish products not yet brought to light, which may
contribute to promote agricultural and manufacturing industry;

X HE superiority of steam over wind as aprime-mover, is suf-
ficiently rect^ised in almost every department of art ; and
wherever the manufacture will defray the additional expence,
almost without exception the first has driv^i out the last. In

at sailing boats, now ten minutes and now an hour in m^ing

There are two ways, however, in which steam may be thus etD>

is the best An engine may be embarked in a lai^ boat, fitted
to rec^ve passengers and goods ; and this method has ezdusiv^
ly been adt^ted, as yet, in this country. Or it may be embuk-
ed in a tug-boat, and employed to tow over large passage ves-
sels, given up entirely to the reception of frights. It is be^
Ueved that this last is very much the better way ; and it may
be observed, as presumptive evidence of this, that it has latdr
been introduced on a great scale, and as a great improvement,
in America. All the reasons, however, for thinking so, have
not yet been brought together nn paper ; nor the subject, con-
sequently, beco considered in the detail which its importance
seems to meriL And an attempt to do this will now dieref(H«
be made.
It may be proper to premise, that the precise system thus
brought under consideration is the following: Two tug-boats
of great power to be kept ; and several, perhaps tm a principal
ferry as many as six, decked passage vessels of different azea,
but all properly equif^ied for the comfortable accommodatitm of
passengers, horsea, carriages, &c. The first to be plied, one at
a time, unless when extrmwdinary circumstances of weather or
pasBi^ require both ; the last to be used, wie or mdiie,
large or small, as the same circumstances may direct. And
the fc^wing are the pindpal reasons which at present occur
in favour of such an esublishntent.
1. Its supericu' ecoBomy to any thing yet devised is very
striking. A large st«un-boat, with a powerful engine, caonot
be constructed much under L. 4000 ; the Dundee boats cost
L. 4600 ; the Buintislaod ones, I believe, above L. 5000 ; and,
if one is kept umstaatly plying, there must be two ; if two,
there must be three, to consUtut« on efEdent establishment any-
where. But the best steam-tugs need not cost above L. SOOO,
tux passage vessels above L. 300 each ; so that two of the first,
and several of the last, would not, all together, much exceed
one of any of the above boats. And that they would be more

that two ooroUaries Sow ttcxa this quality in tha new ^stnn,

which tbey might desire in like manner to encourage.
3. By enabling managers to dimini^ thw incumlMances, ac-
cording to the state of the weather, this system would also vir-
tvalk/ enable them to increase Uwir power, aeeording tA the
same state. In moderate weather, a powerful tug may tow over
i^reral passage vessels ; when it is more bmstefou^ one only ;

eflidency of the Jhicrum is in the direct ratio of their breatlth ;
and, all that it comes ^lort of balandng the oppaalim made to
the boats passing through the water, is just kwt power,—- power
employed in displacing the water, not in moviag tiw boat.
This loss, too, is more considerable thaa may be periiapt tma*
gined. In rowing-boats, even in ordinary drcumstancea, it ia
considered equal lo one-thiid of the whole eiFort ; and is not
probably less in any steam-boat. While in some it must be «
great deal more,— ^is witness the quantJIy of water which they
throw up behind them ; and the absolute tfand still to whidi
they are brought even in very ordinary circumstances of wind
and sea,— their power at the Home time still adequate to its
work, Btill turning the paddles at the UMiol rate.
It must next be observed, however, that steam-boats, which
are intended to embark carriages and psaaengcrs aloagside a
pier, are necesaarily much limited as to the breadth of their ptd'
dies ; they are thus limited for the sake o£ omveBienoe ; and
also, tor a still more a^nt reason. They cany their cargo on
deck, — 4heir ceittre of gravity, when laden, is ooosequently
high, they r<dl deqi, and iheir paddles must be light in propor-
tifHi. Twin-boats also, like those on the Dundee Ferry, ply
th^r paddles at best to great disadvantage, in the dead vottf
betweeo the two boats ; for the aake of strength in their own vat-
structicm, they must have them comparatively narn>v; aodthaur
bulk is «iorinous,and must encounter much oppositicHi in passing
through the water, porticulu^y mlh a head wind. An estmroe

also of importance, as shortening the lever by which the waler
is displaced.
5. It bss just been observed, that steam-paddles ought not to
£p in the water above ^ghteen or twenty inches : — beyond this
pcnnt tbey are found rather to force it down and lave it up,
than press agiunst it horizontally ; besides which, a disadvan-
tageous difference is made to exist between the velocity of the
upper and under edges of each paddle. Steam-boats, however,
plied on the usual principle on a ferry, must every trip plunge
them to a diflferent depth according to thar lading, and in par-
ocular, when they have a heavy cargo on board must sink theoi
greatly toodeepfor their most beneficial employment. They must
thus lose power precisely as they gain incumbrance, lighting the
candle, as it were, at both ends ; and the disadvantage of this
is now so ^stinctly recognized in steain-navigaUcxi, that the
most improved boats, some of the Irish packets for examplej
have a contrivance for raising and lowering their paddles, acoord^
ing to tnrcumMances. The objection to this on a ferry, arises
diiefly &om the trouble of the adjustment, and the little chwice
there is, that in short trips and ordinary drcumstances it would
be suflidently attended to, although not merely the speed of the
boat, but also her wear and tear, will depend upon it. Steam-
tugs, however, which would never embark above a few foot-
passengers, and that coly occasionally, would be exempt from
the inoonveni^ice altogether.
6. It has been ascertained by actual experiment in Amwica,
" lliat, to enaUe a vessel to stem a current with an absolute ve-
locity, equal to half the velocity of the current, it requires Mn»
^mea the motive power, if that power acts on boud the vesset,
that would be necessary, if the pown were applied to a ntfa
hauling her." The details <^ the experiment are not given in

force a vessel up a rapid stream by Bteani-paddles, and by
tracking. But the cases are, to a certain extent, the same. A
steam-tug, by herself, will acquire a momefUvm proportionate to
her qualities, and this momentum, applied to a rope towing ano-
ther vessel, will have the same superior efficacy with that above
stated, to what her power would have, were it embarked on board
at that vessd, — at least, not much less in any case, — in this
poaubly a great deal more ; — and for the following reasons. 1.
A steam-tug, not being thrown out to receive a cargo, having
her paddles, as we have just seen, of the best form, and work-
ing Ihem in the best way, may be expected to be a cleverer ves-
sel than one in which these points are subordinate to other and
contradictory qualities \ — she will thus be well fitted to form the
entrance, as it were, of the whole load to be moved, the sharp
end of the wedge to be employed in cleaving the waters. As
she must have substance also as well as power (bone as well aa
Uood) to fit her for a draught, the weight of her en^e, which,
in ordinary cases, is only necessary incumbrance, will be pon-
tively benefidal to her ; — she will even probably require more
wei^t, which may be judiciously disposed as ballast; and a
counterpoise being thus provided agtunst the top-weight of her
engine, its several parts may be made stronger, and in some re-
spects even disposed more beneficially than in ordinary boats.
Lastly, she will deliver her power in the same straigbt line with
the direction in which the passage-vessel is to be impelled, where-
as the power in tracking acts obliquely. %. The passage-ves-
sel will be absolutely smaller than a steam-boat of the same ca-
pacity, because the room occupied by the machinery wiU be
saved ; she will draw less water, as will presently be shewn,
than would be posnble were she constructed to carry an en^^ne ;
she will be built expressly to tow easily ; will ply in the smooth

ctdated to hare seven-eighths of thdr power disposable for ibe
purposes of draught ; and with this, as above, to draw six tinea

wilt not. The Yarmouth E^ls, which bring stores and provi-
^mis out to the Roads, are open boats, sunk to the gunwale
when "Hteir cargo is on board ; yet no accident ever occurs to
them. The €ani]^he Dn^uers are in like manner square
boxes, with scarce a sharp end to go foremost ; yet tliey too, kiad
gunw^ decp^ bring cargoes out through heavy rollers to ships
four teagues off, and survive all the apparent dangers of their
passage. And men-of-war's flats are currently loaded with
troops tQI scarce a few inches are ^x>ve the water, and with-
out risk. The truth is, that flat-bottomed boats are bo buoy-
ant, that to superSeial observers, who see them move with every
surface vavc, they appear dangeroas craft ; but in the smooth
wafce of a* tBg they would be steady ; in all drcuihstances they
are steady relatively to the water in which they float ; and Uiey
«e tbe ^afesr of all boats : — imd all for the best reasons. Their
bearingg are so low, and if their centre of gravity is low also,
tfie lever which acts on them is so short, that scarcely any impulse
can sink one aide or raise the other. They cover so much
water also relatively to the materials employed in their construc-
tion, that their specific gravity is small, and scarcely any cargo
at any accident can carry them down. And they are by far the
beet boats to take the ground, as every seaman knows.
8. Where open piers are to be approached, on which occasioa-
dly a h^ wind and sea directly beat, this system seems also
peculiarly to. apply. In such circumstances, and within certain
hmits, ssffing-boats may approach the piers, and land one cargo;
but they cannot receive anodier, becauae th^ cannot easily re-
ttim. Steam-boats, on the other hand, cuinot approach at all,
so great is the danger of the piers catching under thdr padcBe-
boxes, and causing f^eat damage. Paftsf^^vesiels alone, which

9- On ferries, where either time is not attended to, or whne,
frDtn the state of the weather, delay is occasionally experienced
in effecting the passage, it must frequently be of importance to
detain the steam-power as short a time as possihle alongside the
> piers, after it does arrive. Large steam-boats, however, as usu*
ally employed, have first to discharge one cargo, and then to
embaric another, before they can poeeibly depart ; and the delay
thus occasioned must be directly proportionate to their oth«-
good qualities^their size and capacity. Where an establish-
ment of passage-vessels, however, is kept, one might be loading,
while another was crossing; and, with a little arrangement and
address, the tug need hardly lose a minute in effecting the ex-
change.
10. Passengers would be greatly safer and more comfortable
in a vessel by themselves, than ihey can posably be when em-
barked with a steam-engine. However constructed, a steam-
boat can never be altc^ther safe or comfortable as a conveyance.
A small neglect of the machinery may at any time cause a great
calamity ; the chances of such n^lect are greatly multiplied
by the presence of passengers on board, and by their occasional
curiosity ; in the event of collision with any external object,
the w«ght of the engine a^^i;ravates the shock ; and if a hole is
made in the boat, she goes down like a stone. On the other
band, the very nature of the engine makes a steam-boat roll; if
she carries a cargo on deck, this effect is increased — her funnel
is all additional top-weight ; and the heat, smeU, smoke, dirt,
and jarring, caused by the engine, ore all evils in their way,
and at least aggravate in no small degree the pains of sea-
sickness. Not any one of these circumstances, however, would
operate in passage- vessels. With the means on board ctf anchor-
ing, passengers would be safe in them, whatever happened;
and wb«% every comer is given up toaccommodation, a thousand
conveniences might be introduced, which are at present un-
thought of.
11. The convenient transport and safety of a great many
bulky articles which there is frequent occauon to convey across
a ferry, would thus, also, be much more consulted than at pre-

sent. At Queenaferry, it is a very proper regulation that hay
and strav shall not be embarked at all in the steam-boat ; and
yet the iDconTenieDce of htnsdng carts of dther into the sailiug-
boats is very great. At Dundee, without perhaps its appearing
as a matter of spedfic regulation, the practice b the same ; and
almost the only use to which sainng4x>atB are still applied oa
that highly improved ferry, is to convey flax-yam, and oUiec
sudi goods, across. Were the steam-power, however, at either
place, embarked in a separate boat, and merdy employed in
towing, such practice might easily be discontinued ; and suling-
boats, with ih&t uncertainty and discomforts, be almost entirely
disused.
in. Upon the tug-system, high-pressure engines might be
again introduced into steam-navigation, and their advantages
secured, without alarm to passengers. These advantages are
greatly undervalued in this country ;^tbey conost chiefly in
original cheapness of construction, diminished expence of work-
ing, superior lightness (nearly as 4 tb 5) ; but, above all, in com-
mand of high power, not for current use, but in reserve agiunst
occasions when it may be required. In low-pressure enpaea
there is no sudi reserve ;-^)eyond a certain limited pcxnt, an
increased fire only fatigues the madiinery, without adding one
jot to the useful efiect : yet in every species of navigation, it i>
important to have it ; in ordinary cases it is furnished by the
morale of the seamen, — and in steam-navigation, it ou^t, if
posable, to be within the fhysiqae of the en^e *. All these
advantages are, however, at present sacriJiced to the apprehen-
coons of the public, — apprehensions in a con^derable degree
overcmne in America, where the subject is more studied, and
the value of modem improvements is consequently more exact-

of ' oiaoagetnent was that one ^Ktuld always be to spare,
tn^t lie a most interesting acqui^don in nutny ways, besides

many occaacHis togs might most essentially serve mercanlile
gitercsts^ in cases of rfiipwreck in particular, from their, grett
power, and comparative lightness oS draught and constructiao,
they might be invaluable in laying out anchors, and in savmg
life ^d prop^ty ; and although such views are not so properly
addressed to public bodies of triistees, incorporated fortmepur-

not be without their value too. A great public acquisition Hwdd

hoid that ferry under a pecuniary obligatitMi), VMild probably

occasions the ferry would itfielf reap the ben^t of this additional
strength : — and if any, or alt, of these considerations would fix
the attention of trustees generally on the superiority, in aorae re-

dude them from the knowledge of, and sympadiy with, humUe
wants. On the other band, it is true that in the esaential qua-
lities of public sfMiit and pCTmanence of intereM, the puUic
naanagement has the advantage ; but this only proves that a
giei£uin between both systems would be better than either :-—
and this medium, it is not the least praise of that plan which
bas now been conadered in so many other favourable pcnnts of
view, tliat it furnishes it with angular security and ease. If
trustees were to find th«r own passage-vessels, they might let
them, with their privileges, bi whatever individuals would pro-
vide the power with whidi to ply them : and if they secured
the perfonnance of the conditions which they chose to annex to
liieir leases, by pecuniary penalties graduating from entire for-
future down to a smart fine for every single intracdon of them,
they need no more scruple at allowing th«r lessee to make oth^
use of his tugs at the same ume, than a coach proprietor thinks
{^preventing the innkeeper who horses his coach, &om keeping
irtiat furtha establishment he pleases, and using it as he Likes.
On xhe contrary, if the system were well understood, it wouM be-
come the greatest recommendation of a. lessee, that he had aqntal
and enterprize sufficient thus to fit several strings to his bow ; and
it may be confidently added, that it is thus (reducing the expence
of employing steam, dwtvii^ a greater efiTect from a snaaUer powtf
(^ it, and permitting establishments of it to serve a variety of
purposes), — and thus only, that high rents can ever be got
fratn ferries, — rents, in some degree, corresponding to the bur-
7% Capt. McKonochie on the mott ^ictive ate ^
deD which they impose on the coniinumty, and to the Bomfices
which have been already made in some places, and, in othen
are yet to make, to place them on an effideot footing. Nntber
need any body of trustees, be^nning such a system, apprdiead
that they would thus deliver themselves, or thrir ferry, into the
hands of an individual. If even a half of what has been ami-
buted to this tug plan really belong to it, (and it is not bdieved
to be over-stated in a »ngle particular), it requires only to be
seen, to be exten^vely acted on. When the present race of
steam-boats shall be worn out, they will be universally replaced
upon this principle ; steatn-tugs, for every purpose at least of
domestic navigation, and for much also which may be called
foreign, will be on the water what horses are ashore ; and tba&
will be the same competition for their supply.
In opposition to so many advantages, I can conceive no ob-
jection to the system whatever, except eome supposed difficulty
in managing two boats together in cert^n drcumstances of tide,
current, weather, &c. To this I would answer, Ist, The thing
has been already done, on the American livra^ at least as rapid
and stormy as any of ours. Sdly, Where there are thus great
advantages to be attained, and only one small physical difficulty
to be overcome, with common talent and energy, if there is a
will there will be found many ways. One at present occurs to
myself as very feasible. Let the two boats be connected by an
inflesible rod, say of iron, broad, flat, and of sufficient strength,
pivoted on the tafi-rail of the tug, and extending out^e 6 or 8
feet to the passage vessel, and 10 or 12 feet inside, till it can be
easily commanded by a wheel like a ship's lilier. Immediately
outfflde the tug let it be jointed so as to play up and down, but
have no lateral motion except what may be given it by the
wheel; and next the passage vessel, let it be fitted with jaws
to embrace her stem and be loosely confined to it by a chain.
With the Iresh way which a powerful tug would give a passage
vessel, and which would insure her towing in a right line with
this rod, the whole apparatus would, I apprehend, just convert
her into a very delicate and powerful rudder in nearly all cir-
cumstances; while it would also communicate to her any glow or

backward movement of the eogioe with certainty and ease.* At
all events, it might be tried or somethiog b^ter proposed.
And I nuy add, that the subject would be a very interesting
coe to experiment on ; and it might well become scnne public
trust to gire the system a trial, even thou^ not altogether con>
vinced of its paramount advMitages. The expence would be
trifling, and the risk none ; for the stesm-power emp1(^ed in the
experiment might be hired ; and a good passage-vessel, were it
even only to be used in fine weather, would be a dearable ac-
quisiticm on any ferry. On the other hand, if the views here
contemplated are in any degree correct, they will apply to many
other branches of steam-navigation, bendes the mere munte-
nance of ferries ;^-the several establishments of these are at the
same time rapidly wearing out, and it would be desirable to as-
certain meanwhile how best to replace them, without, if pos-
uUe, again incurring the enormous expence which already in
many places presses heavy on local and individual resources.
And ihoe is a third application of the subject, which, to some
minds, may be more interesting still. It is not probable that a
steam-engine can ever be onbarked to advantage in a man-of.
war; the nxMn it would occupy, and the casualties to which it
would be there exposed, seem to lorbid this. But in every future
war, steam-towing mutt enter largely into naval tactics ; and a
new interest is thus thrown over the arts of peace, when im-
[wovements in them may be made to conduce to the maturing
of prindplea and practice on which the defence of ail they give
us may yet in tiome degree depend. " Ixirsqu^un nouveau

thod, — but it la a^ to answer very well notwithstanding.
As general principlea, the nearer the two boats are kept together, the
sraootbo', the lighter, and the more manageable will be the draught. And
inOeubk rods, besides their conrsnience for backing and keepii^ Ube boats
apart, will transmit the impulse undiminished j whereas ropes act like iprlnga,
and a considerable portion of the power is expended in merely stretching
them. Hawsers, however, may be well employed as preventers, to take away

But we have no intention to enter into a review of Dr Flaning's
work ; we wish merely to submit a few remarks, as they present-
ed themselves, cm examining that portion of it which is devoted
to the elucidation of Molluscous Animals.
And first it seems to us, that Dr Fleming would have done
well to have quoted more frequently than be has d<H>^ the
" Histcnre Naturelie'' of Lamarck. That work is in general use
amongst the naturalists of i^ie country ; and it is necessary that
the student should be acquainted with its language or sytto-
nymes, whether he may choose to adc^t them or not. This con-
sideration should have prevailed with Dr Fleming, in opposition
to any private o[niiion be may have formed of the merits of -that
production : and it is surdy worth quoting; for the systematio
part is both ably and ingenioudy executed, though we are free
to admit, that the changes in the nomenclature ars not to be vin-
dicated, and the physiological speculations are puerile and ab-
Hifd, and have none of that originality appareuUy claimed.

in colour, and in the number of their whorls, were taken from
beneath one stone. None of them had any smell while alive ;
but, on immersing them, one by one, in hot water, two emitted

a very Mrong alHacemia Boiell, in one it was faint, and in the
other it was not perceptible. It would appear, therefore, that
the animal has the power of retaining of emitting its peculiar
odour at pleasure ; and that, in death, its emisnon may be pre-
vented by accidental (nrcumstances. I could not satisfactorily
ascertain its source; but it appeared to arise from a yellowish
fluid pressed out from above the head. I cannot so unhesitating-
ly assent with Dr Fleming, in conndering the H. caperata of
Montagu as synonymous with the H. striata of Draparnaud.
The latter is the most ctwnmon of all shells in the vicinity of
Berwick, and the white rib within the outer lip is a ccmstant
character. Now, Montagu takes no notice of this in his descrip-
Uon ; and we all know how minute his descriptions are ; while
Dr Turton expressly states, that the H. caperata is to be dis-
tinguished from H. virgata, " in wanting the thread-like rib
round the inside of the lip." Moreover, the figure of Montagu
b not at all like to the H. striata.
Though the ccMistruction of the genera of the remaining land
and aquatic Pubmmi/era might alTord occauon for remark, we
shall now pass on to the naked Branchtfera. tn Tritonia, we
observe, that the T. conmata which is a native of the Frith
of Forth, was not known to the Doctor ; and the two species
which follow do not appear to have been yet described.

same species. Id the former the superior tentacuU are sud to
be annulated, a structure which we did not observe in specimens
erf the latter which we found on the neighbouring coast ; in the
D. papulosa, the lateral papillae or branchial filaments are stated
to be subclavate, in the vermigera they are linear, or conical ;
and the latter wants the bare triangular space on the anterior

Dr Grant to inhabit the Frith of Forth, though not described

The Valvata cristata is mentioned as a native of England

In the Hoiogtomata we could have wished that Dr Fleming

serve to prevail in the establishm^t of genera ; and of which
other illustrations might readily be adduced *. Captain Laskey,
its discoverer, and Mr Montagu, made it a Helix ; Dr Leach con-

80 Dr Geo. Jt^aatao'e Remarks on the datt MoUuko
Mr Lowe removed it to Turbo, and fur dmng so the latter was
rebuked by Mr Gray, who maintained, that, with LiniueuB, it
could be nothing but a Trocbta, and in this opinion Mr Lowe
afterwards coincided, though on grounds which are uniateltigible
to ua. In face of the censures of Mr Gray, however, here we
have it agwn a legal Turbo, — and if the student asks a reastm
for these changes, there is none to ^ve, unless the whim of eadi
naturalist is to be considered as reasonable. If we conrnder the
genus Margarita as unnecessary, and in our humble judgment
it is so, then we submit the species in question is a Trochua, and
we rest our ojnnion, not so much on the general contour of the
shell, as on the structure of the animal. No true Turbo, so far
as we are aware, has the sides furnished with tentacular filaments;
but these organs are general in the Trochi. Now, the animal of
T. margarita has four of these filaments on each ode, and the
jnar^n of the cloak between the tentacula is beautifully cre-
nutate ; and further, the eyes are on pedicels, a character in
which il likewse agrees with Trochus, and differs from Turbo.
The spedes which Dr Fleming has admitted into the genus
PhatianeBa have a very doubtful claim to thdr place ; and none
at all, if we agree with Mr Sowerby in restricting it to such as
have a calcareous operculum. The CmgvUa ptUla, ini^ts view,
is a true Pfiasianella ; and there is, moreover, sufficient in the
structure of the animal to induce us to remove it from the
CingttUa, for these, if we are entitled to form a ccMiclusion &om
the recent spedes common on our shores, have no additional
tentaeula, and a very thin homy operculum. The PhaaianeUeB
of Dr Fleming might perhaps constitute a new genus
The follovring species appears to be nondescript.

the as8«-U(m cS Dr Turton of its having no operculum, hut uo-
fortunately at the period it occurred to us, we were more intent
on collecting species than observing th«r habits and structure,
and can at present add nothing more to its imperfect histcny.
It was my intention to have reviewed in a uniilar mantter the
remaiiung orders and families, but as our remarks consist, we
find, in mere differences of opinion, we shall not extend a paper
which has already exceeded the limits at first pn^>osed. So far
as we are aware the enumeration of the spedes seems most com-
plete, nor do we observe an omistaon except that of Pltmaxii
moUu and a nondescript latithina, which, it is said, have been
added to our Fauna by Dr Leach. We may be allowed also
to express a regret that Dr Fleming should have followed Tur-
ton in affixing the name of the learned Dr Goodall to a genus
of bivalve shells, which future observations may prove have no
clum to a place in the system. Mr Sowerby has already pro-
nounced one of the species to be the young of an Attarte, and it
seems insinuated that the other species has no better claims to be
conudered distinct.

Crvation wad>tbe Deibge,^ Ir.vill be.ue^l to el^*, iheu, how
the explanattbns of the learned prelate have rendered allrational
disputation between science and orthodoxy henceforth impos-
able; it will also eerve to convince religious men that they need
not now, from scruples of conscience, refuse to give their assent
to the sound t1ie<»ies of science ; and^ lastly, it is of importance
in giving a more extenuve diffusion to accurate ideas respecting
the book c^ Geoene, and theprincipal geological focte related
in it, that the useless discussions which frequently arise in the
world may hn avoided ; — «uch, for example, as, disputes vrith
regard to the age of the w(»-ld — the universal deluge — whether
the foBul sh^s were produced by the Mosaic deluge, &c.
By distingui^ing, in the language of MoseS, the expressionfi
m common use, which it was necessary for him to en^ioy, in
order to he understood, and by making altowance for the difler-
ence of times and of nations, and for the genius of the Hebrew
hu^age, and' by adhering, at the same time, to the nurative
c^ the historian, M. de Frayssinous has consecrated, by his suf-
frage, interpretations which have been elidted by a consdentious
judgment. Henceforth the cosntogony of Moses, assuming in
some degree a different character, presents only an assemblage
of facts, which enter, without effort, under the dominioa of the
natural laws, imposed from the beginning by the Creator of the
umverse, and which, therefore, harmoniae with the enhghtened
opinions that may be fiinned regarding the origin of the globe.
For this important observation must not be overlooked : Moses
lays down his cosmt^^ony in few words, and in very general
terms ; and the meaning of the word day being once fixed, we
have only to consider the order and succession of creations there
recorded. M. de Frayssinous shews the agreement thus subsist-
ing between scientific facts and the Mosaic record, viewed in its
true light, and in this respect he renders ao eminent service to
reli^on, to science, and geology.
When, in fact, we call to mind the lamentable disputes which
have taken place, in these latter ages, on the subject of the
Book of Gene«s; when, on the one hand, geolc^, formerly
so theoretical, appeared to encourage the attacks of infidel plii-
losophers, and, on the other, religious men, possessed sometimes
of more zeal than science, denounced, with so much heat, opi-

nions which, al' the present day, give nooffence tq theHg^t^ t^'
the church, — wcare constrained to hold fbrth to pfabltc appro-
bation the spiiit vilh which the Bishop of Hennopolia has con-
sidered this book, and toexlend the' knowledge of the <giioioij8
which he adopts.tHi the fundamental poJnts which it contaifls, —
as thereby furnishing the friends of religion, science, and geo-
logy, who might Btill find themselves exposed to attacks similar
to those to which we have been alluding, with victorious arme
for repelling them.
If, however, there is at the presoit day one truth more than
another to which general assent is given,' it is this — that the pro-
gress of all kinds of rcnl knowledge has entirely banished from
us that spurious philosophical ^irit, of which so mudi If still
said, as if it oould be renewed. What geologist is there, in our
days, who, while be admireB the eitalted genius of Voltiure, is
not moved with pity at his scientific arguments against the
bo<^ of Genesis? And do we now see a single dissertati<wi of
a similar nature, by any writer, enjoying the smallest degree of
reputation in the scientiBc world ? Were a work of this de^
scription to appear at the present day, would not the silence
and dissatisfaction of the learned consign it to neglect, more
prompdy, and with more effect, than the Index of the Sorbonne
could ever have done ? In vain do some interested, or' too cre-
dulous, individuals attempt lo revive the terror of such philbso
ph^rs; there is nothing to justify their alarniB: and did not
every thing aiauod us testify, that science is always the surest
guide for man, geology (whlcb* after having in its infancy fur-
nished weapons against the sacred writings, may now be ren-
dered subservient to the support of the Mosaic cosmogony)
would furnish & iuemorable example. In truth, setting aude
the condderations and Bentiments which command belief, it is
upon M. Cuvier^s reseatvbes that the most important fact in the
MoBfuc record, namely, the order of the creation t^ living
beings,' resti ; it is the investigations, of MM. CliampoUion and
Letronnc, which M- .de.Erayssinous adduces in support of his
historical relations \. and, lastly, it is the discoveries of Dr Youn^
and M. Fresnel that afford the learned prelate the means of
explfuning the passage of Genesis, which refers to the creaticHi
of li^t. 'We are therefore authorized to repd with indignation

the perfidious and calumnioiis ii^nuationB which a dix^ered
mind would endeavour to propagate against men of science in
general, and geolc^sts in particular. All that the learned now
request, is, that they may be allowed to enjoy in peace the fruit
of their labours, and that the cause of religion may not be in-
considerately blended with the results of their inquiries.
We must observe, that, with respect to ourselves, we only
consider the Book of Geneva here as an historical monument of
the highest antiquity ; in other wurds, umply in a scientific
point of view : any other mode would be out of place in the
bulletin *. Bufibn, De Luc, Bucklaod, Webster, &c. have given
great interest to this examination ; and it is time that the con-
■ venlional ridicule which some learned men attach to the study
of this valuable monument should be done away with, when so
much labour is every day applied to the scniUny of the cosmo-
gonies of the Chinese, Hindoos, and Egyptians ; when history
does not even disdain to interrogate the dumb monuments of
the remotest dates, or the most extravagant allegories of the na.
tions of antiquity. Without seeking to support an opinion or
particular mode of thinking, one may take cognizance of a fact,
and intolerance would be as blameable on the one nde as on the
" other.
The Bishop of Hermopolts, resting on St Augustine^s opinion
with regard to the meaning of the word d/i^, expresses himself
in the following manner, on this fundamental question. " The
chronology of Moses dates less from the moment of the creation
of matter than Irom that of tbe creation of man, which only took
place on the sxth day. The sacred writer computes the num-
ber of years of the first man and his descendants, and the chro-
nology of the Holy Books, therefore, is made up by the com.
putation of the years of the succesave patriarchs ; so that it de-
fends less to the ori^n of the globe itself, than to the <»igin of
the human species. Henceforward we can say to geol<^sta,
dig as much as you please into the bowels of the earth, if
your observations do not require that the days of creation
should have been longer than our ordinary days, we shall coo.
tinue to follow the common opinion respecting the extent of
these days ; but if, on tbe contrary, you discover that the ter-

restrial giobe, with its plants and animals, must be much older
than the human race, the Book of Genesis will have nothing to
say against such a discoveiy ; fw in each of the ax days you
are permitted to see so many indeterminate periods of time, and
then your discoTeiies will be the explanatory commencement of
a passage the meaning of which is not perfectly determined.^
Now, observatiiHi shews, that a long period of time elapsed,
lat, between the conaolidatiOD of the primitive strata of the globe
and the appearance of life at its surface ; 2d, between the crea-
tion of the different species of plants, and the various races of
animals ; Sdly, between the latter and the creation of man. The
proofs of these facts are undeniable, as these strata are the pro-
duct of a succession of slow effects, and the remains of plants and
animals which some of th«ii cont^n, suppose a prodigious suc-
cession of distinct generations. The idea, therefore, of days like
ours is repelled by facts ; and we do not even yet possess any
means of estimating the duration of the epochs in question. It
is a calculation of the same nature, as that of the distance of the
fixed stars from the earth, and nothing is more ridiculous in the
eyes of one who is occupied in such investigations, than to hear
people speaking of the age of the world, the antiquity *^ the
world. Sic.
As it is equally certun that the human species is the last in
tJie order of creation, ^nce its remains do not occur among those
of the other living beings which abound in the solid strata,
even the most superficial, of the globe, it may be said that all
the phenomena, whatever they may be, to which the forma-
tions of these strata may be referred, belong to the scientific his-
tory of the epochs, antecedent to the existence of man. From
this may be seen the emptiness of the expression which wc every
day hear repeated, that the revoltdiona to which the globe bean
te»^mony are a proof g/* the universcd deluge. It is evident,
from what has been already siud, that it is at the surface of the
earth only, that we can look for, with some English geologists,
the -traces of this great cataclysm ; and that the ^ells, the bones
cX animals, and the impressions of plants, which are found in
the solid strata of the globe, have no connection with the deluge,
dnce the object for which it was produced was the destruction of
the human race, and as all these strata, as welt as the pheno-
86 M. FT&yesmoas^s Defittce ^ Ckrittianjii/.
Uena which have changed their order or inclination, are anterior
to the existence of man.
God, as M. de Frajssinous has observed, could certainly, by
an act of his will, have created at once the whole consolidated
earth, and all the beings which embellish -it ; but as tiothing pre-
vents us from thinking that the will of the Creatoi' might have
rec^ved its accompli shm«it by a copcatenatioD or succesucm of
effects, inore or less rapid, or slow, with refereiKe tothe duration
of human life, and as orthodoxy makes no oppoaitioD to die six
days' work being considered as six indeterminate periods ofHme;
and, moreover, as Mosies has not entered into a detail of tbe first
causes by which Grod determined this succeEsiinl of effects, and
as the only circumstances which he relates agree with observa-
tion, or with the inference which'^tbe laws of nature authcHise,
we can without difficulty admit this succession or concatenation
of effects, dependentupon first and pre-existing causfes, which has
successively, and in the way of consequence, brought about the
formation of the earth, and the modificatjcms whid Its surface
has undergone.
Following, according to the Bishop of Hermopolis, the series
of the six days' wmk, we shall briefly make known the rest of
this conference.
On the fi[rst day, God created the fteavens and the earth. At
^rst ^ earik icas covered wkh water, presenting the appear-
ance o^ a dark abyss ,- but God said, let there be light, and
there was Ught. With regard to the creation of light before the
sun shone in the firmanient, M. de Fraysainous demonstrates
that the objections which have been madeon this subject are of
no validity ; admitting, always with the learned prelate, that
Moses meant less to say viable and produced light, than the
creation of the subst^ce which may develope light. He fdiinds
his opinion on the reseiuYhes of Dr Young, and those vf M.
Fresnel, which have made the theory of vibrations firevtul over
that oi nnission, which Newton supported. Acconkng to the first
o( these theories, the creation of the fluid whkh was to become lu-
minous, was independent of the creation of the sun, that star
being even considered, nnce the time of Hwschel, as an opaque
body, and therefore light may have been in. fact produced frnn
the beginning.

By the cimtUoo of the heavrai we can only, however, under-
Btand space, aad the bodies vhich compoae the universe, all which
might then have been, as is now, comprehended in that tn-
tletenninate acceptation. But this creation does not absolutely
suppose the existence of stars in the state in which we now see
them. The eun might form part (^ the creation of the heaven,
without having yet that luminous lustre by which it is now dis-
tinguished ; nor do scientific theories oppose the admission of
such a hypothesis. Thus there is nothing to prevent us from sup-
posing that the manifestation of the stars took place only on the
fourth day, or at the fourth epoch. The author has not even
tbought it necessary to mention this observation.
He gives an account of the opinions of geologists or natural
f^iloaophers, respecting the original fluidity of the globe, to
shew that, in fact, the earth was covered with- water. This
ojnnion is at the present day one of the most incontestible facts.
At the same time, observations leave no doubt with regard to
the igneous nature of the fluidity of the globe at the beginning ;
but scarcely had the coaling of its surface permitted the gases
of the immense atmosphere which surrounded it to condense,
when in fact the surface of the earth was entirely covered with
water. Thus the account of the first day's work must be con-
sidered by every mind, not led away with prejudice, and not
seeking in it for that strictness of expresaon with which the
very general terms in which it is delivered are incompatible, as
being in perfect accordance with the &cts and theories ad-
mitted by science.
On the second day, the waters which enveloped our planet,
were divided m ntcb a manrter, that a portion rose inio the up-
per r^iont. On the third day, the dry land began to appear;
flania sprung Jrom ii* botom, verdure and Jlowera etnAeUiah-
ed U. On the fourth, the sun, the moon, and the stars slume tn
AeprrMmmi. On the fifth, fishes swam in the teaieTS, birds
fiOB in Af mr, r^tiies crept in the dust, and quadrupeds tealked
on the Mr/ace of the earth. Lastly, on the sixth, Tium appeared.
The Bishop passes rapidly over all the facts contiuned in this
port of the Mosaic record, with the exception of the work
df the nxth day ; be has not judged it expedioit or neces.
sary, it would appear, to explain each of. these facts in detail,

but confines himgelf to some general reflecdtxis, with the viev of
ahewing that this succeauve furmation of beinge is not opposed by
any authenticated observation. In fact, the second period desig-
nates the time when an equihbrium must have been established be-
tween the waters of the sea and those which are contained in the
atmosphere ; the third, that when the successive diminution of the
waters uncovered the first surfaces of the earth, which hence-
forth were enabled to invest themselves with that primitive ve-
getation, the remains of which are found in the oldest secon-
dary rocks ; but here it is necessary to clear up a difiiculty which
has frequCTitly been adduced as a very embarrassing argument,
and to which recent observalJons enable us to give a satisfactory
explanation. How could plants have grown and propagated at
a time when the sun did not yet shine in the firmament P The
proper heat acquired by the terrestrial globe from its original
incandescence, was sufficient to develope and support this v^e-
tadon, and may explain the apparent difficulty in question.
The central heat of Buffiin, which has thrown so much discredit
on the theory of Uiat illustrious naturalist, is now among the
number of the most accredited facts, and is supported by all the
observations in geology and physics. The phenomena of volca-
noes, earthquakes, and hot springs, can only be accounted for
by this hypothesis ; all the circumstances of which are moreover
in accordance, as M. Fourier has shewn, with the mathematical
theories respecting the coohog id bodies submitted to the in-
fluence of a high temperature. We were the first who, in these
latter times, endeavoured to revive the memory of Buffon with
regard to the fundamental ideas of his theory of the earth,
and to explain all the changes which the animal and vegetaUe
kingdoms have undergone at the surface of the globe, principally
on the ground of the reduction of temperature. Our theory tm
this subject was even extended by a learned Englishman, Dr
CrichttRi, who proved the independence which the ori^oal cli-
mate of the terrestrial globe must have maintuned with respect

of light which leaves no doubt regarding this subject ; so that,
proceeding from this important datum, we not only can conceive
how the primitive vegetation of the earth's surface could have
existed independently of the solar beat, but the same observations

covers the equatorial sones, — and that thus the differences with

£very thing proves that, in this original climate, the periodical
seasooB of our present climates, depending upon the obliquity ot
the ecliptic, and the preponderance acquired by the sdar heat,
had no existence. The proper heat of the earth^s surface ha-
vbg a great elevation, the influence of the sun^s heat, admit-
ting its atmosphere Co have been already in a state of combus-
tion, would have been scarcely, if at all perceptible. What we
have said renders all explanation unnecessary respecting the

tions therdn enumerated is in perfect accordance with the
order in which the fosul remuns of the various races of animals
occur. Animal life was first developed in the bosom of the seas,
then in the air, reptiles followed, quadrupeds next, and lastly
man. This succession, besides being proved by direct facts, is
confonnable with the various jdiases through which the earth*s
surface must have passed, to be successively 'adapted for rec^v-
ing the different races of living beings. We long ago proved,
lit. That the analogy of station and destination, in other words,
of the conditions of existence, and of the office to be be fulfilled,
is the iteneral law which has presided over the distribution of life
upon the globe. S,d, That the changes which life has undergone
on its surface have be^ graduated, but that life itself has not been
renewed ; that the races have not been modified, but that, in pro-
portion as the conditions of existence changed, or as new ones
were f<Hmed, new species occujued the place of those which were
no longer able to exist, and which had no longer an object to ful-
fil ; and that they went on, up to the period when, with respect to
each part of the surface in succession, an equihhrium was esta-
blished between the influenong causes. The animals of these

.yond doubt, that, with regard to animals and plants, it is neces-
sary to admit particular centres or batans of production, just as
we admit in phyucal geography, basins and hydrographic masses
recurring over various parts of a great surface, or in oppodte
continents, and bein^ affected among thems^ves by a variable
number of diflerencee and analogies. At the same time, the
ba^Ds and centres of productions present ^milar, equivalent, or
different productions, according to the places ; and the animal
creation, like the v^;etable, has been subjected to certain ctntdi-
tjons dependent upmi the form and natiu% of the soil, and the state
of the air and waters, so that certain genera, and even certun spe-
cies, are reproduced at great distances, and even upon oppoate
continents, without the possilnlity of supposing that they have
-arrived there by diffusion, or by proceeding from a simple cm-
Ure, or from several distinct centres of production. But these

die last place, with, ref^^nce to its chronolo^cal relalions. On
this subject, we have to observe, that MM. Cbampo]ltoa have
shewn that the chronok^ of the Seveoty, adopted by the fa-
dwEB of th« chun^i is fiufficient to accouot for all the facta re-
corded in history. As to the means wbich God employed Id
producing the deluge, tbi^ although treated by the Bishop at
great fength, is a sul^ect of little importance in itself; the figu-
ratiTe language of the. sacred historian affords no precise infor-
matitxi on this point, except that he speaks of extraordinary
raiiu^ which be must mean by the cataract^ of heaven. God
oonld undoubtedly have diqx>sed of the elements at his will ; but
without having reooulrse to incomprehenuble means, and viewing
the deluge as it ought to be viewed, that is to say, as confined to
the part of the earth then inhabited, some less general phenome-
ncHi will suffice to account for it. '
The coly ptant of importance to be eBtablished is, that the
ddi^wBSDot universal. Respectable authorities are not awant-
ing in support of diis opinitm ; we might, among others, ad^
dace the teBtimtmy of Malnllon, who maintained this opinion at
a meeting of the Ccogregation of the /ndeo! at Rome, where it
waa admitted by the nine cardinals who assisted. The object
of the deluge was the destruction of the human race ; it was
therefore unnecessary to bring a general cataclysm over the parts
<rf the earth that were not yet inhabited. Moses calls it univer-
sal merely with reference to the then lutown earth ; but he did
not cert^nly comprehend under it America and New Holland.
Tbis interpretatirai, while it is more amnstent with reason, and
more accordant itith geological observatitms, which formally re-
pel the idea of cataclysms and perturbations of all kinds, cannot
be conadered as contradictory to the ^rit of the sacred text.

Semarlti on fAe NiOure (;f Sound m Water. By MM. Colla-

wliidi difiWrs in a r^narkable degree from its darstiMi in air.
The sound of a bell struck under water, sod heard at Bome dis-
tance, has no resemblance to that of a bell struck in the air.
Instead of a prolonged sound, there is only heard under water
a short and sharp noise, , which I can compare to nothing bet-
ter than to that of two blades of knives struck against each
other. On retiring indefinitely from llie bell, the sound always
preserves this character, only diminishing in intennty. The
perception of a sound so sharp and short coming from a <Uetaace
of several leagues, causes a fe^Dg similar to that which <Hie
experiences on sedng distant ol^ects through a telescope with
the clearness which that instrument ^ves to them. In makii^
the espetiment at intermediate chstances, the sound always ap-
peared to me the same in nature, insomuch that I found it im-
possible to distinguish whether it came Frora a strong and distant
stroke, or a weak and near one. It is only at a distance of about
200 metres, that the rin^Dg of the bell b^ns to be distinguish-
aUe after each stroke. In the air we observe a pbenomoion al-
most entirely the reverse. The strokes applied to a bell are
more distinctly heard at hand, whereas at a distance there is
only heard a continued and almost uniform tingling. The re-
nstance which the water opposes to the vibrations of the beltj
does not afford a sufficient explanation of this fact, for the saint
sound heard out of the water was much more prolonged ; the
sound of a bell was very well recognized, which would have been
impossible, in listening at a distance to the same noise transmitted
in.water. This phenomenon is explained by the nature ot the vi-
brations of sound in water. It is known, in fact, that, in the vibra-
tory motion of a fluid, the duration of agitation of a particle is
equal to the radius of the spherical porUon of the fluid which is
originally shaken at the commencement of the motion, divided by
the velodty of transmission of the sound. The first of these
two qualities is necessarily smaller in water than in air ; the
second, on the contrary, is greater ; whence it follows that the
duratioa of sound ought to be much less when it is transmitted
through water, than when propagated in the air.
The second remark relates to the 7ion4ratumission of the found
Jrom leater into air, wheu the vibrations which are propagated
in the water arrive at its surface under a very small angle. Thus,
Rentarks on the Nature ^ Sound in iVater. 93
as I have stud, at a diataoce of less than SOO metres, the sound
(tf the bdl struck under water is easily heard in the air ; but,
•t s greater distance, ita intensity diminishes very rapidly, until
at length, at the distance of 400 or 500 metres, it is imposuble
to distinguish the slightest sound, even very near the surface of
the water. However, on immer«ng the head a few centimetres,
or by putung down a tube filled with air, as I did, the sound
of each blow is heard strongly and distinctly, and in ^his man-
ner it is heard at a distance from ten to twenty times greater.
It is evident, that, at a distance of 500 metres, the vibrations ar-
rived at the surface under a sensible angle^ which was further in-
creased by the curvature of tbe earth. The vibrations which
take place in water, do not therefore communicate with the air,
when their direction meets the surface at a small angle, — a pheno-
menon analc^us to that presented by the surface of separation
of two mediums of different densities.
The agitation produced by the waves does not alter the du^
ration of sound nor its velocnty, when a tube is used for hearing.
The last of iJie three experiments mentioned above was made in
stormy weather. The wind, which at first was weak, increased
to such a degree, that several anchors were necessary to hold the
vesseL Notwithstanding the noise of the waves, I could still
distinguish pretty well the sound of each stroke, and the dura-
tion of its transmission was not altered.
The last observation which I have to make, relates to the
i^uence of screens on the intensi^ t^ sound. Having chosen
two stations, at no great distance from each other, and so situat>
ed that the straight line which joined them grazed the extremity
of a thick wall which rose above the level of the water, I had
the bell struck r^ularly, and with strokes of equal intensity.
Hearing them with the tube alternately on nther side of the
line which grazed the extremity of this wall, it appeared to me
that there was a very marked difference of inten^ty, according
as this extremity was or was not interposed between the bell
and the tube. The transmission of sound in water, tberefc^re,
differs in this respect from what takes place in air, and ap-
proaches to the mode of the propagation of light. This influence
of a etseeen inseuEdbly diminishing the intensity of sound, deserves
to be remarked, and affords a new point of approximatimi be-

Obaervations on the Fluids contained in Crystallized Minerals.
By William Nicol, Esq. Lecturer on Natural Philosophy.
Communicated by the Author.
To PK^easot Jamesqij.
Dear Sib,
Xjeing under the necessity of going into the country, I can-
not at present continue the investigation I was engaged In, con-
cerning the fluids contained in the cavities of crystallized mine-
rals. I shall therefore now give you the result of the observa-
tions I have already made.
About two years ago, when polishing a fragment of a 6rysial
of sulphat of barytes, having a cavity containing a fluid and a
small moveable globule of air, u partial rent took place from the
surface into the cavity. The consequence was, that the globule of
mr immediately began to expand, and continued to do so until the
whole of the fluid was expelled from the cavity. The fluid did not'
form a continuous line along the rent, but appeared in the form
of three or four distinct globules, one of which was considerably
larger than all the rest After inspecting these globules for some
time, and seeing no change in their appearance, the fragment
was laid aside. On examining it next day, each globule was
found to be a solid crystal, having the primitive form of sul-
phate of barytes, namely, a right prism with a rhombic base.
The waste by evaporation, if any had taken place, must have
been very little, for the crystals seemed to be nearly as large as
the globules from which they resulted.
Some time ago, I found in my cabinet a crystal of sulphat of
barytes, containing several cavities, in each of which there was
a fluid, and a moveable globule of air. With several of these I
have succeeded in getting the fluids to the surface through par-
tial rents, in consequence of the expansive foi ce of the air. The'
fluid always oozed out in the form of distinct globules, of differ-
ent magnitudes, one of which was generally larger than all the
rest. The globules, however, from diflerent cavities, assumed
different appearances. Those from one cavity, for instance,

irsxe neuljr h^nupberical, md seemed of coosiderable deiiaty.-
tboee fnMn other csvitiea spread out to a ooa^dentbte extent, io-
dicadug less tenacity, and a greater attractioo, between the par-i
tides of the fluid and the surface on vhit^ thej spread. The
globules, too^ form dilFerent cavities, ory^lized with very dif-
ferent decrees of rapidity. Several minutes elapaed before the
dense hemispberical globules of one cavity b^;ui to crystallize.
The crystallization then went on slowly, and was not com-
pleted until after the lapse of twenty-four hours ; whereas most
of the thin flattened globules from other cavities, crystallized al-
most the instant after they reached the surface. The dense he-
mispherical globules seemed to lose very little by evaporation ;
but the thin flattened globules seaoed to suetun a very consU
derable loss by that process.
In the instance first menUoned, each globule of the fluid
formed only one crystal ; but in all the others, each globule gave
forth a eonaderable number of crystals. These were always
arranged in a curve, immediately within the circumference of
the globule. Sometimes the crystals were aggregated together,
sometimes they were more or less detached, and sometimes a
detached crystal or two formed within the curve. The whole
of the crystals had the same form, that of a right prism with
a rhombic base.
£ince, therefore, the cavities, in sulphat of barytes, evidently
contain the matter of that substance in a fluid state, it seems
fair to infer, that the cavities in other crystallized minerals may
contain their own matter in a nmilar state. This I have late-
ly ascertained to be the case with fluor-spar. About two months
ago, I succeeded in forming a partial rent in a crystal of that
mineral, containing a cavity with a fluid and moveable globule
of ajr. The instant the rent took place, the air beg^i to ex-
pand, and continued to do so, until the whole of the fluid was
expelled from the cavity. The fluid appeared on the line of the
rent, in the form of twelve distinct globules. These were tena-
dous, and of a hemispherical form. One of them was much
larger than alt the rest put together. For several hours after
the fluid came out, there was no appearance of crystallization ;
but, next morning, a number of cubical crystals, aggregated in a
curve within the margin of the Urgest globule, were distinctly

viable. The crystals were completely immersed in the fluid,
together witJi a few minute globules of air, which had come out
of the cavity. The crystals daily increased in bulk, with a
corresponding diminution of the fluid ; but a fortnight elapsed
before the crystallization of the fluid was complete. Even then
a slight degree of moisture could be observed on the surface
of the crystals, and aJ«o on the space included within them, and
this moisture still remains. Some of the globules, which are ex-
tremely small, still remain in a fluid state. When the crystals
attained such a size as to come near the surface of the fluid, the
edges of the upper surface of some of them gradually rose above
it, and these have now the form of an inverted four-sided pyra-
mid, a form which is oft^t assumed by muriate of soda, when
slowly crystallizing.
The elasticity of the globule of air in the cavities of all the
crystals I have yet examined, is evidently great, for whenever
a rent was formed, the globule, however small before, always ex-
panded to such a degree, as to expel the whole of the fluid. In
the cavity of fluor-spar above mentioned, the globule of air ex-
panded to more than the size of the cavity, for a part of it even
escaped along with the last portions of the fluid. Indeed I
have repeatedly found the elasticity of the mr to be so great,
that when a direct opening was suddenly formed into some ca-
vities of sulphat of Irarytes, the whole of the fluid was blown out
in an instant, not a trace of it being left behind.
I have observed a very curious property of the globule of air
in the fluid cavities of various minerals, These globules, when-
ever they are moveable, always occupy the upper part of the ca-
vity in which they occur ; but if the end of a heated wire be
made to touch the surface of a crystal next the under side or
end of a cavity, the globule of air immediately descends to it,
and that, too, with a rapidly accelerating motion. On removing
the wire, the globule immediately ascends to its former posi-
tion, but with a uniform motion. Perhaps you can aflxird an
explanation of this phenomenon. I am, &c.

On covering the Rot^s <>f Houtes vnth Plata ^Iron. By
M. E. Caktek, In a ktter to the Editor.
Sir, ExeUr, AprU 8. 1SS8.
My attention has been recently directed to some observationa
in the last December number of the JBdinburgh New Philoet^bi-
cal Journal, upon my scheme for coveiing the roofs of build-
ings with plates of cast-iron. Your principal ot^ection is found-
ed on an apparent imperfection at the junction of four of the
plates, which does certtunly, at first sight, appear as an obstacle
to the success of the scheq)e, and is what in truth occa^oned me
to he^tate, before I determined to adventure any thing upt»i
the matter ; but, satis6ed upon more mature r^ection, that
wliatever water might be driven into that comer, must ulumate-
ly be conducted to, and fall into, the lower plate, and from ihat
plate to another in the like position, until finally led to the eaves
or gutters, I determined to try the experiment, and had a set of
plates cast and put upon a roof, the result of whit^ was com-
pletely satisfactory ; the experiment roof having, besides with
odiers (since erected) withstood the violent hurricanes of last
Wbruary, without the displai^ment of a single plate, or the ad-
mts^on of a drop of water.

think you will be satisfied of the impossibility of forcing any wa-
ter over the corner of the lower plate.
In point of taste, nothing can be worse than the roofs of our
modem dwellings, which, with what are termed hips and val-
leys, ju«s«)t a series of irregular pyramidal forms, intersecting
each other in a most incongruous variety, indescribitbly disa-
greeable to the eye. The valleys also cau«Dg, in many cases,
the nuisance of smoky chimneys, and sometimes an inundauon
of the dwelling, upon the breaking up of snow.
In the application of this prefect to the covering of dwelling-
houses, the upper parts of which are usually divided into rooms -
of moderate dimensions, it will be found that no trussing is re-
quired, and consequently there is a considerable saving in timber
and labour, the partitions being sufficient support for the raft-
ers whereon this covering is laid. I am. Sec.

AT has often been remarked by travellers, that, in eastern
countries, deformed individuals are seldom or never met with.
This circumstance is attributed to a variety of causes, as par-
turition being less difficult between the Tropics, the temperate
halnts of the people, &c. ; but, if those who assign these reasons
for abortions b^ng of unfrequent occurrence in the East, were
to inquire a little more carefully, they would find that imper-
fectly formed beings occur a^ often in eastern countries as in our
own. Why, then, it will be asked, are they not met with ? The
answer to this is short. They are destroyed immediately after
birth by tbdr unnatural mothers, and commonly by placing a
small opium piU in the mouth of the infant. Some of these
unhappy beings, however, are occaaonally preserved ; and, as it
fell to my lot, during my peregrinations in the East, to meet
with several singular instances of Lusus Naturse, I now pro-
pose shortly to describe some of the most remarkable.
I. During a march from Jaulnah to Arcot, I halted one day
at the town of Hachootee, in the Ballaghat ceded districts. 1

wu Bitting at the door of my tent, whidt was jntched in a man-
goe tope or grove, and was enjoying the cool erening breese,
(after the nice diyiog temperature of 105° and 110° during the
day), when I saw a. singular being of about three feet in hei^t
approaching tne. He came up to where I sat, and, with a low sa^
laam, asked mj pardon, and solicited charity. On a cursory
glance, he seemed to have hia arms tied behind his back, but,
upon desiring him to turn round, I found that he had been de-
prived of these members by the hand of Nature.
This singular httle man was arrayed in a pur of loose white
long drawers, with a sash ; his body was naked to the waist ;
over the left shoulder he wore the zunar (the sacred cord of the
Hindoos), and on his head was an ample turban. His age
seemed to be about thirty ; his head was of the usual size of an
adult, and fully developed, and well formed in every req)ect.
The scapula or shoulder-blade of the rig^t arm was in its pro-
per place, but the arm itself was wantii^. The left arm was
entire, including the os humerus, fore^arm and hand i but, what
was most extraordinary, the whole tum was enrdoped in the
skin of the trunk, no part of it b^g viuble, escept the third
{^alanges of the fingers, which protruded dose to the left pap.
This arm (the left) was doubled back, so that the elbow touch-
ed the vertebree. No dcatrix was perceptible on any part of
the external cuticle, and the motions of the incarcerated arm at
Uie will of the abortion were most wonderful. The thorax was
very considerably distmled, and the abdomen was scarcely ob-
servable, as the short ribs rested on the pelvis. The left 1^
was four inches shorter than the right ; and, to sum up the p^
culiarities of this dngular being, theses were the rudiments ottt
rixth toe on both his feet. Deprived of the use of his arms, be
was obliged to feed like a brute, by thrusting his head into the
vessel which contiuned his food ; and, unlike some individuals
of a nearly similar malformation, he derived no asastance {ram
his feet in performing any function, except in bdng able to run
with tolerable speed, but in a most ludicrous and surprinng
manner. — Plate I. Fig. 1.
II. In the Basar at Arcot, there was a boy who, at a little
dt8tatKe> might easily have been mistaken for a dc^ ; in faetj he
100 Lieut. Alexander oti Lutue Naturte
was comnuMily called by the Musselmans cholera »ug la, or the
dog-like boy. He walked on his hands and feet with his head
thrust forward, and waa unable, without considerable pain, to
erect his body to an upright posture. The cause of bis extraor-
dinary gait was, that the pelvis being much distorted, the femo-
ral bones were so placed in conjunction with it, as to cause bis
legs to be at right angles to his body. His kne&goinu brang
stiff, and his legs being much shorter than usual, his body is
quite horizontal, and he walks about with seeming ease to him-
self. He is iJx)ut fifteen years of age. — Plate I. Fig. 2.
III. There was also at Arcot a little mat-maker, the forma-
tion of whose hands and feet was very peculiar. They were
like the forceps of a crab, the skin covering three and two of
his fingers and toes, and causing them to resemble claws. He
plied his vocatitm with hands and feet, and produced as neat
work as bis brother mat>makere. Plate I. Fig. 3.
IV. I have frequently seen in India four legged chickens,
double-headed pups, Sec. but these mtHisters sinL into insignifi-
cance when cmnpared with the one I am going to describe,
which is a quadruped, the pxiduce of a sow, and littered at Kur-
nou) not long ago. The mother brought forth a fitter of pigs,
all of which were naturally formed, with the exception of tbe
monster in question, which came into the world alive, but sur-
vived only a i^rt time after its birth ; and is now preserved in
^rits, and in the possessioa oi Capttun Wallace of the Staff of
the Madras Army. It exhibits the following extraordinary
appearances in its confOTmaUon.
It is half a sow and half an elephant. In addition to the or-

j^s from the bottom of the forehead ; tbe monster has likewise
got the pendulous ears peculiar to the elephant; and the n<»-
trils are seated at the extremity of the ele^antine proboscis.
Thift noo-descript is a Cyiilops, for, upon raising the prehensile
trunk, a single and well formed eye- is observed,, the aze of
which is considerable in proportion to the bulk of the monstn* ;

J. N the ordinary and arduous operations of collieries, there daily
occur many difficulties ; such as, an escessive extra quantity of
water which requires to be drawn to the surface ; bad roofs,
which must be constantly guarded and secured, for the safety of
the adventurers and miners ; and crushes of the coal pillars, and
of the whole superincumbent strata, which frequently resist every
attempt to stop their progress.
Bemdes these, there are others, such as the constant Sow of
carbonic acid gas common to every colliery, by which many lives
are lost, and the production of carburetted hydrogen, peculiar to
collieries in particular districts. In Scotland, the carburetted
hydrogen is most abundant in the Ayrshire and Glasgow Col-
lieries ; in England, in the districts of the rivers Tyne and Wear,
in the counties of Northumberland and Durham. The first of
these gates is named by the miners in Scotland, Choke-damp,
Black damp, and Styff; the latter is generally named Fire, or
Fire-damp.

The fiFBt species of gas is comparatively eanly guarded agaiDBt
and aT(»ded ; the latts is subtile, — the very pestilence and bane
of the miners, — springs into action as instantly as the lightning
of heavcsi, producing the most feaiful destruction, and the most
appalling catastrophes, sweeping before it men, horses, and ma-
terials, like chaff before the wind, in one mingled mass of horri-
ble ruin.
These disasters, though Tiolent and dreadful, are happily of
short duration ; and the bold, unyielding, and persevering spirit
of the miner, in a short time repairs the wreck ; the labours are
resumed as if no such disaster had taken place, and that with a
degree of cbeerfulneBs which has greatly surprised every one.
There is, however, an accident of a different kind from these
before mentioned, which, though in general very dow in its pro-
gress, is most difficult to overcofne, because, though slow in
progress, it goes on unremittingly, gains strength hour after
hour, and day after day, and, in many instances, puts the skill
and persevering exertions of the miner to defiance ;^this is,
comtn<»i burning fire in the coal mines, the ignition c^ the coal.
This fire arises from three causes : Is*, From the flame of a
blower in the coal, from which the carburetted hydrogen issues
with such violence, and in such quantity, that the noise is fully
louder than the noise of steam issuing from the valve of a steam-
engine boiler, when fully opened, and steam in abundance with-
in the boiler ; or, by tbe blast of an explosion, which is a maga-
zine of blue and white flame, of intense heat, which sets fire to
the small coal-dust of the roads in the mines ; for this fiery blast
never sets on fire the soUd coal, though the blower does so in
some instances ; 9dly, From spontaneous ignition, which is the
most common, arising from the decomposition of pyrites amongst
the coal rubbish ; for, however abundant the pyrites be among the
solid strata, and though in contact with water, no decomposition
takes place, but, in the loose rubbish, the contact of air will soon
produce fire, particularly if aided by the contact of water or
moisture ; Sd^, From accident and inadvertency by the contact
of common fire with the solid coal, or with the coal rubbish.
For the extinguishing of these fires several methods are in
practice. In some instances, the fire, if not of great extent, or
only very recent, can be put out by throwing water upon the
burning mass ; but if pyrites abound, tbe apphcation of waler

necMMty to run tfaia liak ; and, when the 6ie ia extinguished,
to take meiBsures for preventing a recurrence of the acddent
If the 6re can be approschedt th« e&ctual plan is to shovel
it out, and send the burning materials up the pit to the surface.
In this service die miners are sometimes dreadfully scorched ;
but what is more dangerous are the deleterious vapourB arising
from the fire, which are very much mixed with the fumes of sul-
phur: these oflten so much overcome them, that they drop
down, and they are then dragged, like dead men, to the fresh
ur, where gener^ly they soon recover ; but the effects are such,
that they t^^^ suffer in their health for years after. If, how-
ever, the miners lie, for any considerable time, in such air, very
few of tbem can be, 1^ any means, reanimated.
The next plan b to choice the fire, as it is termed, by shutting
up, with clay-puddle, every pit and mine connected with the
burning mass. This, in many instances, succeeds ; but we have
seep instances where such means were ineffectual, and Uie fire
continued to increase, by drawing a supply of air to support com-
bustiop through cracks and crevices, which are sometimes c^n
fnw) the surface, and are unseen.
When the fire exists near the dip part of a cfdliery, where the
draoMge is performed by machinery, the fire is easily extinguished
by stoi^Mng the maiduimy, and allowing the water to grow up.
If the lire is toward the rise or out-crop, this circumstance sus-
pends all the colliery operations, until the water is again drawn
off by the machinery. On the other band, if the rubbish is full
pf pyrites, the spimtiuieous ignition is greatly increased by the
water hastening the decompoution of the pyrites. Hence there
is, at best, but a chince <^ evils.
If poaU on fire have a level free drainage, it is, in most cases,
impovaUe to dam up the water ; and the only resort is, to extin-
'gvisb the fire by amotheringj and preventing the access of air.
In the collieries in StafKirdshire, particularly in rhe coal named
the Ten Yards Coal, actually thirty feet thick, and which I
have frequently examined, spontaneous ignition is very frequent.
The miners term it, in that district, the Breeding Fire, because,
without any vinble contact of actual fire, the coal rubbish be-
umesred hot.

Fires in the mines there have been for long an every-day oo-
currence ; and Bometimes such la the intennty of the fire in 90
thidc a coal, that near the surface it bums with a white heat,
melts the argillaceous achistus into gtass, and converts the pure
ar^laceous earth, or fireclay, into a substance amilar to the
hardest porcelain. But what is mc»« remarkable, the common
argillaceous ironstone frequently assumes the appearance of re*
gular basaltic columns, of about an eighth pari of an inch in
diameter. This a^regate mass is ao hard, that it is found
equal to any material for making turnpike roads, and is so ap^ied.
At ffilston and Dudley, in Staffordshire, these fires at pre-
sent exist. At the latter place, I Tinted a garden of connder-
able extent, where I saw, from the influence of the subterraneous
fires, the snow melting as it fell upon it ; and not only very early
crops of T^tables are raised there, but no less than three crops
of them in the year. Of this garden there is an account in
the Caledonian Horticultural Society's Transactions, sent by me
to my friend Mr Neill, our secretary ; and it is worthy of my
particular remark, that although the fire is near the surface of
the eardi, all the beneficial effects of moderately increased tem-
perature are found, and no detriment results to the growth of
vegetables. From this drcumstance Intimate oonclusiona may
be drawn, as to the existence of central fire in the earth. This
^eory I have long supported, md I thiitk it «an be substantiated
by sound and philosophic arguments.
In the early periods of working this coal, the spontaneous ig-
nition very much vexed the miners. They had no proper system
then of working so thick a eoal, on which Bc«>unt they sunk a
great number of pits within a few yards of e&cfa other ; they then
wrought the coal from the top of the bed to the pavement, like
the frustum of a cone, very wide at bottom ; they made no ex-
tended worka, as they were so liable to take fire, but, abandoning
one pit, instantly commenced another ; and over the top of each
deserted pit, they built a cone of brick- work, like a bee^ve, to
prevent the (ur having access to the coal. Many of these pits are
to be seen near Dudley, in a circumscribed area, very close to
eadi other, not unlike the ant-hills found in forests.
In the progress of mining, the working of this celebrated coal
has been much improved, and extenuve workings are car-

When a jHt is sunk to the cools, minea, termed Headwaytf
are run from both ddes of the pit, in a level course diiecticKi as
a main road a, a, for brining the coais frcnn the miners to the
bottom of the pit, and at regular distances, according to the
system pursued by the mining en^neer who directs the colliery
operations ; openings are made in the coal, next to the pave-
ment, or rock, on which the coal-bed rests, which openings are
about eight feet wide, and seven feet hi^ : these are termed
boU-hciie», and are marked b ; from these bolt-holes the wtvking
of the coal is extended, and by these the excavations, marked c,
are made of from two to three hundred feet in width and
breadth, and there is left around each excavation a strong bar-
rier of coal, as represented in the figure, to insulate the excava^
tion.
As much small-coal rubbish, mixed with pyrites, is left within
the excavated area, if the free access of air were permitted
thereto, spontaneous ignition would soon take place ; but this is
commonly e&ctually prevented by placing a stop^nng, as it is
termed, in die bolt-hole. At first this was done by atones
and common rubbish, but iJiis was in many instances found to
be ineffectual, and the most secure method is proved to be, by
building two walls across the bolt-hole, composed of loose stones,
at some distance from eadi other, and filling up the space be-
twixt them with mine dust, that is, with the dust of calcined
iwostaae, produced at iron works. Tins, aided by the mois-
ture of the mines, becomes a sohd mass, quite impervious to
air, and is not injured by the crushing of the strata, as is the
case with stone walls, whit^ are crushed mto a loose powder,
through which air will pa^. By this ample method, sponta-
neous ignition is now generally prevented in the Dudley district
In the north of England collieries, namely, those on the
rivers Tyne and Vfear districts, wh«e the coal occasiooally
takes fire, the danger is exceedingly increased by the presence
of hydrogen goa, which sometimes accumulates, then fires and
explo4es at the burning mass ; accumulates again, and goes off
at r^;ular intervds, loud as the thunder of heaven, when the
bright blaze of conflagration is succeeded by a darkness so

interne, Hut, in fignrabye language, it may be fdt. This sioguUr
feeling is quite familiar to those who traverse miwR. In this
oaae then is no alternative but to choke the fire, by MeaHng up,
M it vrm, the shafts or pits. Thw b no ea^ matter, for the
shaft, in nuiny otses, dare not be entered by any living ravature,
witliout almost instant deslJi, and to cover the mouth of the {Mt
would be quite ineffectual ; the jdan, thereftn^, is to lower a
stroog wooden sesffi^ by c&bles or cbain^ to a cooadenble
depth down the shaft, and then to throw many leoB (^ pjtriic
day down upon it at randen, which in the fall mokes a stdid
puddle ; but if there is water in the shaft, a precaution is necei^
sary, otherwise the water accumulated above the scaffold would
in all [KobabiUty break the chains or cables. To obviate this, a
long pipe requires to be put through the seaffi>ld, recurved like
a shepherd's cnxAi at the top, in ord» to allow the w^er to
descend, without the admission of air.
In other cases, where the fire is in the coal-dust fit the roads,
wu) flamiDg, and no hydnogen gas is apprehended to exist near
the Are, small extinguisfaiag engines, fitted for ijie mines, are
used, and frequently with good effect ; but whw the Agiiies
camot be applied, the flame has been in some instances extin*
guished by the power of sudden cancussiiin, produced by the
filing of cannon as close to the flames as possible. This ^ect
is wdl known, and this method has been again and again pn^o-
aed fcr extinguiahing fires m buildings.
Such is a very brief account of the j^ans pursued for extio^iafa-
ing fires in coal-minesy^i-^subjectof deepintenestto the pix^Hie-
tors ef mines, and, in particular to the mining engineer, who is
id£n cidled, in such cases, upon duty, has to nA his ]t&,flnd the
lives of his assistants, and to use every means which science and
pcBotice can suggest, to extinguish the ^re. This sutgect is not
only very iatererting to the inhatntaots of Great %itmn, but to -
the world at large ; for, in such trying ^nations, men meet on
ooDunmi ground, and, with kindred feelings, are ready to afford
every aid in th^ power, as in the storm and the shipwreck,
when natitmal distinction ceases bo «ust.

colliery, the property of James Wemyss, Esquire, M. P. in the

tively eafdly overcome and extinguished.
Kilkeiran Colliery is situated on a hill ; and the drainage is
effected by a day level, which lays dry several beds of coal. It
is said this colliery was set on fire by some herd boys, who were
amunng themselves with a fire they had kindled at the moutb
of the pit. This fire is reported to have existed for more than a
cratury ; far it a)^)ears, in some of the oldest maps of Ayrshire,
publi^ed in the banning of the last century, that this c^Kit is
named the Burning HiS, which iiatne it fctcuns to the present
day.
Every attempt to extinguish this fire has proved ineffectual,
w both water and choking by bed air has failed.
' The fire was for aome time confined to one bed of coal, the
working of which had to be abandtmed ; but, in order to have
tlie jvoduce of oo^ from tlus colliery, the workings were pur-
sued in a ooel under the one which was burning, and I was in-
fimoed by my frigid, the late William Dixon, £squii«, of the
Calder Iron-workfi, one of the most experienced and suocessfut
nifl«'a of his day, that he surveyed the co^ which was working
under the burning otaes, where he found the miners in a heated
atmosfAere like an oven ; Utat the drops of water which fell from
the roof were seizing hot, and die candles were melted by the
heat in the mine. In aome phcee, at the surface, the argidace-
ous sdiistus had been m^ted into a glass or slag. This diews
with what resolute and fearless determination mankind at times
pursue their labours, and with what danger they oftea earn
Uieir bread. This burning district of the colliery has been loi^
^Mndooed, and the mining operations are now carrying on in
the valley of the Biver Girvan to the south, clear of the burh-
ing. From the heat which existed in this hill, and its diffuting
itself equally at the surface, it was observed during the winter,
that the snow which fell melted immediately over a consideraUe

extent of the surface, and that the herbage in winter was of a
lively green. This induced the proprietor to convert part of this
ground into a nursery, for the rearing of forest trees ; and it
succeeded admirably, as the trees grew vigorously, and very
quickly ; but when they were removed from this genial clime,
produced by the subterraneous fire, to exposed atuatloDs, the
severity of the climate killed the plautB, from the suddentiess of
the change of temperature.
This circumstance also shews how the internal heat of the
globe may diffuse itself in high latitudes, near the surface, and
produce in some d^ree the favourable effects of the climate of
the equatorial regions, in pUce of injuring vegetation, as we
would very naturally imagine.
The Johnstone Colliery took ffre by spontaneous ignition
above twenty years ago. It consisu of five distinct beds of cool
lying close to each other, forming as it were one bed of coal,
constituting a thickness of above forty feel ; and in one place,
these five seams are overlapped, and constitute a thickness of
about ei^ty feet, which is an anomaly in the British coal for-
mation. It is also remarkable, that it is in a district abound-
ing with h^ compact greenstone ; and the engio^-pit, where the .
drainage of the colliery is effected, commences in a bed of green-
stone at the sur&ce, which is no less than 108 feet in thickness.
When this coal-mine took fire, it instantly burst into flame,
and there being an open lur-course betwixt two {uts, it gained
strength, and burned with uncommon fury. Figure 7th, Plate
III. represents the situadon of this mine with the two pits.
The fire commenced at the pmnt a, betwixt the two pits ; the
atmospheric air descended the pit £, and passing through the
burning mass, carried with it an immense volume of smoke,
which ascended the shaft c, and issued at its mouth, forming a
ct^umn of pitchy blackness, which rose to a great height
into the atmosphere, the air bdng calm. This had a terrific ap-
pearance : it continued in this state for some time, until this
dense vapour was heated to the igniting point, when it suddenly
bunt into flame with a very loud explouon. This biifj^t aa-
pinng flame, as thick as the volume of the jnt, was at least se-
venty feet in height, and produced a very fearful but sublime
object. It instantly burnt down the machinery for drawing the

coals at d. This flame could have been immediately suppressed,
by covering over the [uts b and c with baulks of wood and wet
clay ; but there were horses at the bottom of the shaft b, bo that
if they had shut the pts, the horses would have been instantly
suffocated ; on which account, the minds of all concerned were
turned to the saving of the poor horses. The men, therefore,
went resolutely down with the descending air at the jat b, slung
the horses in succesnon, and sent every one of them separately
to the surface, and then they themselves ascended. The two
jnts were then covered over -, but as all hope <^ extinguishing
the fire, either by water or by contaminated air, was hopeless,
exertions were made to confine the fire to its <nreuni scribed
place, and stone-walls w^« built in all the openings betwixt the
pillars and around the fire ; which walls were made air-tight by a
Uitck coating of lime-plaster. This has had the desired effect,
and the burning has been confined within these bounds. This
fire still continues, and an opening is kept at one of the pits, to
allow the sufibcating v^wur to escape, otherwise it would con>
taminate the fresh air where the miners are working. When I
viated this colliery a few years ago, I found (he heal still very
strong, as it issued from the opening left in the pit ; and when
examining the mines, I found the plaster upon the walls had
very little warmth. I have no doubt this fire will continue (o
bum within these bounds for a long p«iod of years.
I examined tbe wastings of another pit in diis colliery some
years after, where the process of decompoution had commenced.
There I found the heat so great, that the nmrns were all d
them working naked above the girdle, as the beat was to them
exceedingly oppresnve.
Dysart Colliery has been frequently on fire in the main coal,
which is fully eighteen feet thick. One part of this coal coa-
t^s pyrites, existing rather in a comlnned state with the coal,
and not very visible to the eye. Many years ago it burnt with
violence, and extended progressively to the outcrop near the
surface, where the common blue schistus has been converted into
a brick-red colour by the heat. This burning created much
trouble and expence, attd it was extinguished by insulating the
burning coal from the main body of the coal-field, till the fire
. exhausted itself. It has now heea extinct for a considenble

number of years ; yet, at the present time, when the co«l~rid>-
Uah ii allowed to lie in heaps of considerable thickness below
ground, the incipient ignition is detected, and the TubUsh has
either to be drawn up the shaft, or spread very thin along the
pavement of the mines. Great caution is diul; necessary there,
to prevent spontaneous ignition, which is soon discovered by a
peculiar smell (well known to the miners), difTusing itself through
the wralcings.
The Alloa Colliery took fire about twenty^four years ago, in
the nine iWet coal at Collyland. This was an accidental &e, oc-
casioned by a. candle igniting dry rotten prop-wood, which was
in an old part of the mines, and of the nature of touchwood.
It took place while I was traversing the wastes with my ofr-
ustant. We made a very narrow escape from sufibcation, as
the ignition took place rapidly, and the etadke ascended the pit
very soon after we came to the surface. Every effiirt was made
to extinguish the fire, by closing up the pits and preventing the
access of the air, but all attempts were iueffectua], and the burn-
ing continued for upwards of ei^teen months.
As it was necessary to cairy on the colliery, the miners were
ODployed in a coal immediately above that whidi was burning ;
but it frequendy happened, that, while they were working, and
while their candles shewed no sign of bad or vitiated air, they
dro[^)ed down lifeless, and had to be carried to the Acsh tax
ere they revived. This was an anomaly as to the test of pure
air familiar to the miners, and ^ws ^t this vitiated air mising
(vxa. the burning, when mixed with the common air of the mine,
will support the flame of a candle, but not anim^ life. This
circumstance indicates what extreme caution is necessu-y when
men enter mines where a fire exists, as their utuation, in this
case, is extremdy dangerous, and therefore no person ought to
.enter such a mine alone, or even with a ^ngle assistant. A
number should always go tt^ther, and keep at a short ^stance
from each other, in order that immediate asastance may be ^ven
to the front men in case they drop down. In this colliery, I
passed through a quantity of this deleterious air, not knowing
tlut it was there. I had only one assistant, and we very nar-
rowly escaped. Upon our coming to the surface, I found no
bad tSfeO* ; my assistant, however, sulbvd much, but recov»-

The wastes or excavations of this coal were coonocted with
the wastes in an adjtnning estate. The subtile effluvium passed
into this estate, and, at about a mile distant, ascended a pit, and
Icilled the birds which were near its mouth.
After eighteen months, the fire became tenously alamuog,
and we then had no alternative but «ther to allow the buroing
to go <Hi, or to drawn the colliery, and render it us^se until
some after-period. This last was resolved on ; the pumfnng
mgjne Was stopt, and as the growth of min&-wat^ was compa-
ratively slow, we brought a brook along the surface, and allow-
ed the water to pour down the engine pit, where it felt in a cas-
cade of about SOO feet in depth. By this plan the fire was ex-
tinguished, but the colliery remains drowned and useless to the
present day.
The Hallheath C<^iery took fire in a acAid bed of coal, which
was level-free, hut had not been wrought. The crop of the
coal was on a bank near one of the great pumping en^^nes, and
the red-hot ashes from the furnaces of the en^e-boilers wer«
inadvertently laid ag^nst this bank ; these set on fire the coal,
and the fire extended by slow degrees in a amjde state of incatt-
descence, and continued in this state for years. Its progress was
only arrested by a slip of the strata, which acted as a barrier
against the farther jHogresa of the burning. This shews how
easily, in some cases, even a bed of solid coal may be set on fin;.
The Bridge of Orr Colliery was set on fire by spontaneous ig-
nition, duiing the severe winter of the year 181S. It is a con-
tinuation of tije thick co^ of Dysart before mentioned. During
this severe winter, many rivers in Scotland iroise to their bed^-

ner ; and when a sudden rain and tliaw succeeded the froat, the
accumulated waters dowed on the top of the ice, and a cwside-
raUe quantity ran down the colliery pits. This water caused
a decomposition of the pyrites, the consequence of whicb was,
that fire and flame were very soon generated. I was called up-
on this occaaon ; taid as the burning was con&ied Ut a oarrov

space, the workmeti, at great riak of life, sfaorelled together the
bumiDg coals, and sent them up the pits ; and when thej were
unable to do any more from the extreme heat, and suffocatii^
vapours, the remaning hurning mass was smothered by cover-
ing it over with very wet puddle ; after whidti the colliery ope-
rations were resumed.
The Wemyss Colliery was set on fire, a few years ago, by a
quantity of small coal being accidentally Itud over a brick-flue of
an underground high-pressure en^ae. This fire rapidly extend-
ed, and has occasioned much trouble and expence. It has burn-
ed for at least three years ; and as the burning mass was iosu-
lated, I think it very questionable if the fire is altogether ex-
tinct.
I was sent for upon this occasion, and was able to get very
close to the burning mass. I found the men, who were attend-
ing and giving their assistance below ground, very much affect-
ed by the deleterious vapour ; their faces were pale, and thar
eyes had a glazed or varnished-like appearance, — a drcumstance
I have frequently noticed in similar cases. Upon my returning
to the bottom of the engine pit, I found the sulphurous vapours
very much affecting my head ; so much so, that I requested the
men to tie me to the rope, in case I should have fallen during
my ascent. The effects of this vapour produced a most violent
headache, which continued three days. During this burning,
many narrow escapes were made ; and two unfortunate young
women, who were carrying breakfast to their relations in the
mines, fell victims to this most insidious vapour.
Having thus given a summary view and account of the chirf
fires which have taken place in the Scotch Collieries, I have now
to state the particularB of the three recent fires, which have taken
place in Clackmannanshire, and in the collieries of Mid-LothisD.
The fire which has taken place in the South Sauchic Colliery
is in the old workings of the nine feet coal ; which are of very
great extent, and very ancient.
About three months ago, this coal was discovered to be on
fire ; and the susjudon arose from smoke issuing irom the sur-
face of the earth. This coal is not liable to spontaneous igni-
tion, as it is very free trom sulphur ; and many conjectures were

it was observed by stxne of the miners, that the snow, dunog
last winter, soon melted at this place, they never once suspected
diat fire was the cause.
In the tool of this nine feet coal is a very valuable argillaceous
ironstone, wrou^t by the Devon Iron Company, for thrir fur-
naces. Vat the wmHcing of this ironstone, they sunk a [»t of

as is commonly the case with sucli heaps, without the least dan-
g^ bnog apfvehended fnun it ; but it is certain that this was
the cause of the present very alarming fire, which is now of con-
siderable extent, and, if not extinguished, may extend over a
foSf of excavated coal ; and not only so, but by making t^e
rocks red-hot, may extend to the upper beds of coal, and occa-
sion. an excessive loss to the district There is also a risk of it
burning the coal-pillars in the middle of the pit d, and rendering
the machinery erected upon it useless for dnuning the five fert
coal-seam, which is situated thirty-nine fathoms iinder the said
nine-feet coal.
This very hazardous situation of matters required instant and
very detnded action for extinguishing the fire -, and, after all cir-
cumstances were w^j^ied, it was found that water could not be
tilled, nor could it be effifcted by drowning, as the water would
neva rewb this pert of the colli«y, ^en aldiough the engjaes
for dnumng the water were stopped. It was therefore resolved
to run a mine all around llie burning mass, to insulate it from
^ other parts of the colliery, and to allow the fire to exhaust
ilielf within these limits. Tbis operation b now in progress,

as they proceeded, they came lo the bcMly of Kerr, whitdi,
frmi feeling, they found to be hfeless. Sommerville instantly
concluded that they bad deviated from the direct path by winch
alone escape could be made, as they had not found Kerr in that
pn^iresB inward ; they resolved, therefore, to retrace tb^ steps,
but they had scarcely determined to do so, when SommerviUe's
remainii^ cooipanion Brown, said to him, " Vm gone !" and
instantly fell down. Sommervilie, for some while, crept on his
knees and bands, but the muscular energy of the arms soon fail-
ed ; he then crept on his knees and elbows, but made very little
progress, from the extreme feebleness and relaxadtm of the. sya.
tem. He, however, resolved, as a (M-indpleof self-preservejion,
to keep in motion, as be was yet sensible that if he lay down
he would Id all likelihood perish. In this way he ctmtinued for
ftbout an hour and a half, and made only a very few yards pro-
gKBB. While in this most trying situation, such was bis intense
•Qxiety for the appearance of men foi his relief, that he fre-
quently imagined he saw the lights of candles, like twinkling
stars ; but his senses were such, that he reasoned with himself
th^ this was all delusion. At last relief came to him, and he
was carried out quite exhausted, by two of his componioflB.
The four others who had come down, boldly and determioBtely
went (Xiward, and found Brown apparently lifeless. With great
difficulty tbey carried him towards the pit, and. immediately
upon their copiing to good and fresh air. Brown shewed signs
of reanimaiion ; and upMi being drawn up to the pit top, he,
in a shwt tiuke, so far recovered as to be al^e to walk home, sup-
ported by two ci his compamons.
As there were medical gentlemen in attendance, the ordinary
methods for resuscitation were tried with Kerr and Davidson,
but without effect, and they found that Kerr bad been smed
with a locked jaw. The others who escaped were attacked with
vomiting, which is a common consequence in such caaes, and the
cmly other bad efiect tbey felt was violent headach,— 'whicb also
is a common cuisequence.

deeompoBitioii of the pyrites. About three months ago the
burniDg became strong, and the mamiger of the colliery, Mr
Deww, having ascertained wher? the mass of burning materials
Was, with much prompdtude and decision perforated the ma-
sonry of an adjtBning pit, where he knew there was s Band>bed
with much wat«r, and having made wooden pipes, conveyed this
water down the shaft to the pit>botlom : from that point he
carried the pipes with the water horizontally through the wind-
ings and turnings of the mine, and poured the water upon the
verge of the burning materials. This very dangerous service
he accomplished in xhe most expeditious manner, and it does
credit to his sprit and zeal. He saw, however, that although
the water was poured upon the burning mass, night and day, it
was impos^ble to throw it upon the great body of the fire. At
this crisis I was sent for, and 1 was able, by keeping close to
the fallen roof, to approach within a few yards of the fire, which I
found burning like a furaace, and the superincumbent rock strata
red hot. The hot air immediately above our heads floated tall
of smoke, and was insnlFerahly hot, so that it was dangerous to
nuae up our heads, and we felt that the roof above us was ooa-
aderably heated.
Ait^ crmsidering all the circumstances (^ the case, we re$oi~
ved to cut a mine, if posnble, around the burning area ; but af-
Ux CMiadarable exertion, we found tbb impracticable ; and we
saw in the course of this trial, that the roof had fallen to a con-
nderable height, and that die fire had communicated itself to an
upper bed i^ coal. The case then became critical and alarm-
ing ; every circumstance of the mines was considered, in order to
devise the best plan for extinguishing the fire.
The coal was level free, and the colliery had a drainage
through other adjoining collieries ; from this circumstance the
discharge of the water could not be stopped by ordinary means.
The eight feet coal, in which the burning was, is situated
^ven fathoms above the splint coal ; and the water of the eight
feet coal descended the pits to the splint coal, and there dis-
diarged itself. To this lower coal, five pts communicated.
We therefOTO resolved upon the following process to extinguish
tfie fire. At each of the five jrits, and at nine feet below the
pavement of the eight feet coal, grooves were cut in the rock,
lis Mr BaU m iheWirfAat takeplttee in Cotterm.

iy with boards, and Dve> this was laid a weil wrought olay pud^
die ^ht feet thiek ; and in order that the aeciunulatcd water of
tile raises might be dmwa off at pleasure, oastonm pipes with
■nive* t^ tsf) opening upwards, were inserted through the scaf-
ftdding aud puddle, in two of the pits toward the dip, and a
Npe from eadi of the valves was secured near Ut^ mouth of each
pit. These pipes had a collar cast ufx>n them, so as the pipe
mig^t ivst upon the faoe of the scaflolding.
Tha seeAoa of the colliery is represented figure 5, Plate III ;
and the tbober scaffolding with the oky puddle, pipe and valw,
are reprssmted figure 6, Plate III.
While the bunung was gnng on progresavely, the Srai\ air
descended the pit a, figure 8, paEsed through the bunung mass
at c, and the vapour and smiJce osoended the pit 6, in a mode,
rate volume and slowly. In this pit b, there was a stair fiw the
nen descendnig to the mines, and as this was the pit to the
nw, or crop, the air, as a natural consee[ueoGe, always aaceqded by
that [Ht. But as the communication below thei aght feat coal
at the pt b had to be stt^iped, it was altt^flteF impossible to
Bocomplifl) this while the stair reeiained ib it, teoA no man durst
venture down one fathom without losing his life. It therdbre !)»•
came necessary U> reverse the currant of air, so that the fresh
ur might descend the ^t b, and ascend by the dip pit a,
eiontrary to its natural course. IV) eifect this, a laiige ifi^n
grate, capal^e of hi^ng nearly a too of burning coats, was sus-
pended by a chain in die shafi a ; the fut b wfta then covered
over at the t<^, until the shaiY a became heated by the fire in
the grate ; then the scafiUding was quickly removed from the
Biouth of the pit b, and the reverse circulation inMaatly took
place. The miners then with perfect safety removed the st^r— ■
cut olf the communioation to the sp^nt ooal at the pavement of
the ^ght feet coal, — and this being accomplished, the grate
with the fire, was removed ftnm the pit a, and the (»rcu)atiati
retunied to its ordinary course. Me^time, the watei- being

pheric ait, at aome distance from tbe pit mouth : so hot were
the st««m and ait that they lioged the baira <m the back of tbe

Ihe iJonlute t«(D|Kniture' I could Qot ascertain. This baj^i^ned
upDB the 8th day of March 18SS. I requested Mr Devar, the nia-
nager, to try the temperature frequently ; and, upon tbe ISth <ff

wtwds, aqd, on the Slst May, the ■ last day on which I have a
r&piM of the tempetature, the themiometcr stood at 84°.
As this sufcjject is vety interesbng, tite r^pster of the tem-
perature as taken by Mr Devar is annexed.
We therefore condude, that the fire is about extinguished,
and that our labours wii) be sucoessfuL We now expect that
the temperature will progreadvely lower by slow degrees, be*
cause there is a vast mass of heated rock, onniderably above -
the immediate contact of either water or steam.
It has been a matter of phymcal investigation to show by what
chemical action spontaneous ignition is generated in those coals'
where pyrites abound. Air and mmsture aeetn to be indisprasa-'
bly necessary ; and it it also requi«te that the coal rubbish be of
considerable thickness,— for, if it is only a foot or two in thick- '
ness, the decompo^tion.will lake place with a very small degree
of heat, but fire will nM be the consequence. In this case, it
appears that the heat is disupated the instant it is formed ;
whereas, when the he^ is of several feet in thickness, there is
a certain degree d {wessure, and the heat, as it is formed, accu-
mulatee. Tins accumulation ef caloric hastens the more ra|Hd ■
decomposition, when beat is also move nq»dly generated, and
that to the point when actual ignition ctxnmences. The beat .
and fire which are generated in wet hay, se^n to depend on at-
milar circumstances ; for, without accumulation and pressure,
actud fire w91 not take place. As to the chemical action, seve.
nd prindfdes may be acbng, namely, the decomposition of at-
mospheric air, when the iron of the pyrites seizes the oxygen of
the air, and sets the iatent caloric free ; the oiygen and hydro- ,
gen of the water may highly contribute to encrease the tempe-
rature ; and we know that it is a conHnon occurrence for the
cotd rubbish, which is mixed with pyrites, at the mouth of pits,
to take fire from the sune causes ; hut depth and pressure are
(dways necessary to produce the result.
What I have thus narrated, and explained by dif^frams,
(diews the risk to whidi mines of coal and miners are exposed ;
in particidar the latter, who are brought into the most tryii^
situations, surrounded with darimess and the pestilence,— when
the mind has full time to CQnten^tlate the danger, and the
approach of death ; and when the thought of home, of a wife,
and of children, touch the heart with the most painful^ and
Mr BakI on the Firu Oat take place in CoOieriet, IM
most intraae soliatucle: a situation altogether differeot fnm '
tbat of our brethren who are Burrounded with death, in the Any
of battle, <Mr in the overwbdmiiig stonn of the uplifted ocean.
In these last cases, the hurry of action, and the neceiSBiy con-
tinued ezertitx), give but little time for the mind reflectbg on
^iproaching fate, or on the ties of friendship, or of home, and
Us endearments.
Such casualties in coal-mines as I have described, shew the
necesfflty of great watchfulness to prevent the generating of fire;
or, if generated, of {wevcmting its becoming irresistibly power-
ful ; and also, how necessary it is to act in all cases with prudent
dedsion, having, at the same time, in view a due care for the
Jives of the workmen, who, in evety instance, when required, go
with cheerful alacrity into danger with those who conduct the
necessary op^vtions.
To the laborious and hardy miner we owe mudi ; not only,
as r^^arding many of the comforts of life, but also as regud-
ing ihfai direct influence in increasing our national prosperity
as the greatest manufacturing country in the world.

hand being quickly withdrawn.
The festhen generally be^ to move slowly ; in a few se-
conds th^ uniformly turn the pmnts of their filaments toward
the source of Ught, and tbdr ades beang parallel to the direction
of the rays ; imd whenever they assume this relative position
tbey rest. If the flame is placed opposite to the lips of the fea-
thera at once, they move little, <»- not at at). If the rays <^
Kght are made to fall upon dieir planes, at angles of 40", 90°, or
150°, they will traverse only to the extent of these degrees, and*
then remain stationary.
The gdd-leaf, fat the first hour ot two after it is fenned into
a disc, and put under the cover, ^ews extraordinaiy sennUlity
to the influence of light. It indicates the efltets of the light of
a candle at the distance of fimn 15 to SO feet from the flame.
If not kept in the dark, and in vacuo, it soon loses this suscep-
tibility ; and, in six or raght hours, will not move at a greater
distance frtmi the flame than two feet.
The gM leaf always turns the edge of its disc to the light, in
whatever pontion the cuidlc may be placed.
The niver leaf is equally senntive to the impulses of light,
and never loses this property to the same extent as the gdd. If
thonniglily dry, and placed in vacuo, it indicates the influence
at light, wh«t 90 and ft6 feet lUstant fixHn Uie flame of a candle.
-Sevml of the leaves tried, whether kept m vacuo or not (if
preserved from the U^t), when exposed to the attnuitive and
repulsive properties of the rays issuing from the flame of a can-
dle, always moved toward the light, at a distmce of nght and
ten feet. The «lver leaf has a movemoit pecuhar to itself. It
first turns the front of its disc, and then its edge ; and this move-
ment is often so constant that it will osdilate for hours io an arc
of 90*. When it has lost part of its susceptibility to the im-
pressions <d light, it is so attracted as to move till its disc con~
fiiMtti the source of the light In this state, it Ujks its vibratoiy
motion, and takes a minute or two to traverse 46°.
The gidd'beaters' leaf moves at the distance <€ m feet from
the flame. It turns its edge to the point from wbidi the ti^t
flnanates, and then rests.

disc ia about five iiu^es diameter, move, by the influence of the
light of a candle, at the distance of three and four feet.
As the light passed through the glass of the cover, whkti
would intercept any degree of heat, whilst it admitted the hgbt,
and as the movements beg^n generally in a few seconds, th«e is
no reason to believe that any incremmt of heat can have any
^lare in producing the motions.
All these bodies, however, nwve to the influeuce of he^ when
it proceeds from a given point, at various distances. Yet the ef-
fect of heat ia evidently Tery ioferbr, in point of power, to the
influence of light.
A jnece of coal, for example, two inches square, ijpiited to red
heat, when presented to the velvet disc with the filings, only »-
cites it to move towards it, though held close to the cover ; but
if it is exposed to the clear rays of the sun, during summer, as
EooQ as it has absorbed a certiua quantity of the rays, it is stroog-
ly replied, and will continue, when first made, to r^olve fbr
hours without intenoisnon, performing each revolution in about
5". They all turn their edges to the point from which the heat
proceeds.
Effects of the Lunar 3eam.-^Ai the candle used in trying the
effects of light on these bodies was of a moderate uze, and as
there appeared to be little di&r^ice between ita illuminating
powex, at 15 or 40 feet from the flame, wod the light afforded
by the moon, when nearly full, it did not appeat to the author
unreasonable to expect, or surpiinng to find, that the discs were
afiected by the influaKe of the lunar rays, m nearly a similar
manner. They were mode the subjects of expmment both in
the open air, under the cover, and in a room with the windows
shut. When tried in en apartment, Uie window was darkened,
and they were made to rest (by moving the stand a little), in
sudi a position that the raya of the moon, when admitted, fell
upon the discs nearly at right angles to their planes. They all
turned their edges toward the luminary, and their planes nearly
parallel to the incidental beams ; and they frequently miuntained

These facts agree with some priiunplee generally received, as
estaUishiag mwiy' crancideaces betweoi the [:Jieito[neiia of light
.and electridty.
Some farther obs^vadaiiB were made on the effects of the
rays of light on hodies of different forms. While bodies
hAving planes, turned their edges towards the source of the
. light, and their flat udes parallel to the lipe of iocideiice, bodies
of a concave shape vacillated continually in an arc of from 5° to
45", according to the inteputy of the beam of light. Bodies of
a cylindrical form, crossed the line of incidence at an angle of
about 25°. Transparent lenses (as of amber) keep their , axes
parallel with the incidental rays. And spherical opacjue bodies,
when mcely suspended or balanced, have the tendency to re-
volve continually when the b^ms of the sun fall clearly upop
.them.
Some aj^Iicaticma were made of the phenomeiia described, af
farther elucidating facts already known, as the attraction of the
kiaves and petals of plants to the light,-~-the formation of crys-
tals, — the knowledge that birds and quadrupeds seem tp possess
of the fwvtiiHil points, as probably arising from the sensilulity of
tbw hairs and feathers to the impressions of light, ele^icity,
and magnetism, and through them to the na'vous system and
sensorium. As farther explanatory of the ptdarity d the neecUe,
if any current of magnetism is allowed to exist, and of the diur-
nal variation of the punting and dip, as dependent on the mo-
tions of the sun: And from the principle that Ught attracts bodies
ot the parts of bodies that have been in the shade, and repels
.that wluch has been for some time exposed to its inguence, pro-
dudng by this means a ccHiUnual revolution in bodies of a sphe-
roid form ; it b thought probable that this may be one cause
of the diurnal rotation of the earth and the planets.
It has not been observed that any of these bodies indicate
the electrical changes of the atmosphere ; because the chai^;efl
in respect to them must be genial, or affecting each part ot
tbm equ«Uy> l^e ulver-leaf, indeed, has someUmes a curious
vibratory mo(j<Mi ; but these vibrotioos are evidently regulated
by any beam of light &lling on (he disc. Two of the discs
suspended aa two pivots, and opposed tQ each other, would no
doubt act as an electroscope. ...

On the Hiaiory and ConatilutUm of Benefit or Friendhf Socie-
ties. By Mr William Fbaske. (Concluded frwn ftHuier
Number, p. 3)3.)
OiNCE the publication of the former number of this Journal,
Mr Courtenay lias brought into Parliament the bill which we
then alluded to, for consolidating atid amending the lawB rela-
tive to Friendly Societies. The benefits offered to these sodetics
in Eftgtand, by this statute, are (except the power of settling dis-
putes by arbitration, wbich is to be repealed) nearly the same as
those which they formerly enjoyed ; namely, that thdr money
may be p^d into the Bank of England, to account of the oHicers of
the National Debt Office, at a cert^n high rate of interest, — that
both principal and interest shall always be at the command of
the office-bearers of the sodebes,— that they may sue and be sued,
and their property invested, in the name of thdr office-bearers,
in the same way as is done by incorporated bodies,— and that
no bond or other security given to or on account of any socie-
ty, ^all be chargeaWe with stamp^]uty. It is further pro-
posed, that all former acts regarding these institutions shall be
repealed, — that before any new society, or any old one re-
quiring alterations in its rules, shall be hereafter entitled to the
. benefits of this act, its reguladons and tables must have been
submitted to, and approved of by, the officers of the National
Debt Office, and the Quarter Sessions of the Justices of the
Peace of the county wherein the society is situate, or intended
to be established, — that persons, assessed to a certiun extent for
the rehef of the poor, must be nominated trustees, in whom all the
society's property shall be vested, who shall not be removeable,
nor obliged to find security for thrar intromissions, without
thdr own consent, and who shall have the sole appointment
<^ the treasurer, — that societies shall periodically tran^nit to
the National Debt Office, through the clerks of the Peace,
returns of their accounts and afiairs,— that no alterations on the
rules or tables of any society shall be lawful without the consent
of the trustees and approval of the Justices,^ — that the Quartn*
Sesdras shall have liberty to make such alterations as they may

■ 810 Mr W. Fraser on ihe History and ConHihitum of
think pn^MT, — aoA that the Justices in Petty Seseioiis shall
alone be c(Hnpet«it to dedde every question that may arise b^
tvreen societies and thrir members, without the powei; of any
appeal whatever.
These extram-dinary enactments have be«i thought neces-
sary, not atiy to secure conl^butions adequate to the pnHnised
benefits, bat also to putan end to the penuraom system of- Aia-
nagement which at present obtains among Friendly Societies
in Ei^land. The meetings there are ccMnnitHiIy held in public
houses, the publicans are in general the treasurers, peculation
to a great extent is siud to Jirerail, and the menbers are laid
under the necessity of spnu^g a large sum anntudly at the
monthly and anniversary meetings. -
This is very different from the manner in which Friendly So-
^eties in Scotland are condocted. The most rigid economy,
and, in general, fidelity exist m tbdr mant^ment; the ser-
vices of all the office-bearers, with the exception of the clerk,
have be«i hitherto mtirely gratnttous ; and their meetings are
held in schotJ-rooms, or other ^milar places, quite unconnected
with public-housefi. It may be therefore saf<£4y said, that not
mismanagement, but miscdculation, has been the cause of fu\-
ure with Friendly Societies in Scotland ; and it is gratifying to
be also able to state, that active measures are now every where
taking to rectify this important defect, and place societies upon
the most secure baas. Owing to these circumstances, itisb&-
Heved, the |»t)posed tnll was not intended to apply to Scotland.
' So long, however, as the above pernicious mode of 'manage<-
ment prevails among sodeties in Ikiglabd, it is naturally cott-
eluded, that any rules or tables, ^wever accurately framed at
first, will be ultimately rendered of no' avail ; and it has tlm«-
t&K been conceived that an end should be put 16 Uiis system by
the Legislature it^f. But sbcieties, On the other 'tetiH}, c<»i-
sidersuch interference as an infringement of the rights of ih-
fividuah to manage tb^r own affiiirs, and- a^ totally subver-
sive of the independence oftb^ institutien?. ■ The clauses re-

i; — and. the cODBequences have been, that very gsHeral
dissati&factitm and abmnbave bees excited throagbout Eoglaod ;
petitioDs against the bill have been poured into Parliament from
every, quartfti:,. and ithas been ultimately found neceoaary, not
-only «ooaderaifly to oiodify it, but even to delay any fartlier
fMuce«ding8 durivg the present aeasoo.
It cannot be deitted, that the objects proposed tt> be atttaned
by this statute arc highly laudable, and that some measurfV
should be taken to remedy the evils ooinj^aHied of i but it is to
be reg^tlad,. ttwt the mirans which have at present been resolved
oo, are perhaps imoog the most objtetiondsle which could
have been devised. No body of' men, aseodated for harmless
and useful purpoeea, however in^iuficant these pnrpoMB
Diigbt be, would Bubmit to be imperativdy dictated to, and to be
pWed Hlkl»r die entire oontroul of the inferior magistracy, with
r^ard U> the msBogement of their own funds and concerns. It

^inr^anes. Doubts and .anxiety would be thereby created
in th^r mintb, the subject would be investigated, they would
soon become .convinced of their errors, and new societies would
be inmiediMely instituted upon improved principles, and under
proper management. Soci^fy m^mb^^ would soon perceive it
to be their interest to join these new institutions in preference to
the old ones, notwithstanding every influence that publicans and
132 Mr W. Praser oti the History and Corutitvtion of
others, intereated in their schemes, might possess ; and the sup-
jdj of entrants being thus cut off from them, they would very
speedily alt cease to exist.
The success of such simple but effectual measures has been
already completely exemplified in Scotland. As soon as the
Highland Society of Scotland published thar Report on Fiiend-
ly Societies in 1824, copies were sent to the head magistrates of
burghs, to the convener of each county, for the use of the clerk
of the Feac«, and to all the persons who had sent in Returns,
with a request to the ma^strates and conveners, that the «»-
tents might be made known to any sodeties in the vicinity.
By these means, a spirit of inquiry was soon excited, sodeties
became convinced of the erroneous prindples on which they had
been instituted, new sodeties immediately began to be founded
upon more secure bases, these are now rapidly increa^ng, ani^
although their contributions are higher, they are universally pre-
ferred to the old institutions, whose schemes it has generally
been found impracticable to improve. Let these or similar
memis be resorted to in England, and the same effects will un-
doubtedly follow.
We formerly gave a brief detail of the investigations in-
to the rate of mortality among mankind, and endeavoured to
shew, from various sources, that the Northampton tables xk
unfit for the practical purposes of health and life assurance.
Thb has been since completely put beyond doubt, by Mr John
Finhuson, actuary to the Nati(»ial Debt Office, who has shewn,
to the satisfaction of Government, that the country has for
some time been losing about L. 6000 a-week, or upwards of
L. S00,000 annually, by the state annuitants, in consequence (^
the value of their lives having been calculated by these tables.
A ImI! has therefore been brought into Parliament this sea.
non, and passed, few repealing the statute by which such an-
nuities were granted, -and which annuities must still, for a long
time, remain a heavy burden on the country. It is now evident,
as was formerly i-emarked, that the premiums calculated by
the Northampton tables^ mid demanded by life assurance com-
panies, for sums payable at death, must have been very mudi
in excess, since those for annuities were so far deficient ; and
hence the propriety of the lower rate of mortality adt^ted by
Benefit or Fneniiy Societks. \S&
the Highluid Society of Scotland in cidculaUng tables for
Friendly Societies. Having already given some of these tables,
we shall now proceed to illustrate more fully the principles up-
on which they were framed, and the mode of u»ng them, for
the purpose of investigating the state of societies' affairs.
As b^re fVequently observed, it is esseuti&l to the permuieiice of every
sodety, tliat there should be calculated ai the commencement, the amount of
coDttibution which will be required to defray the contemplated benefits, so
that all the members, the last as well as the first, shall be innired of al-
lowances corretponding to their payments, and to their ages at entry. At
first u^t such a calculation may appear very difficult, if not altogether im-
ptBcticable, owing to a Friendly Society being a body conrasting uf all ages,
varying In numbers from time to time, and the demands for uckness and death
also varying in propoitioD to the number and ages of the members. But, to
simplify the procests instead of viewing a society some time after its com-
meDcement, let one be supposed to bave just commenced, and to be compowd
vi infividuala cjtber of the same or of various ages, who are to contribute cer-
tain sums annually on the one hand, and to receive certain sllowances on the
other, till a hl^n* age, or till all are dead. Were the pcc^reaa of suet a so-
ciety to be traced, and a distinct account kept of the contributions and allow-
ances of the original members till all bad died ; and wen^ It found, that all
they had paid in during life, with accruing interest, was ei^uivalent to the
whole they bad drawn out, also with interest, it might be inferred, that, so &r
as these persons were concerned, their contributions and Bllovaticee bad been
properly adapted to each other. Were the progreJjs of a second, a third, and
afburtb body of members to be noted, and the same results obtained, it might
then be safely concluded, that that sodety was established upon se^-ure prin-
ciples. There would lliuH be ascertained, lit, the total amount of contribu-
tiona; 2il, the rate or number of weeks' uckness which bad occurred at each
age, and lor which allowances had been paid; 3d, the number of deaths, the
ages at which they had occurred, and the disbursements on their account ; 4|A,
the interest which bod been received for the capital: B<A, the interest which
bad been lost on the allowancest and, iatUg, the total amount of the expendt-
Again, were a number of societies to be conducted in the same way, and
their whole results found to lead, although not exactly, to the some general
cmclusions, an average of the whole could he taken, and such an averse
might with safety be adopted as a standard for the guidance of societies in
future. It may be observed, that it would not be even necessary for all
these socleUes to have had the same rale& of contributions and benefits. The
only things requisite to be ascertained, would be the number of weeks' akk-
nesa, and the number of deaths that had happened at eaoh age or class of
ages; for these being known, any given contribution could be accurately cal-
culated tor any spedfted allowance.
Now, although Friendly Societies, so ftr as is known, have never kept any
such records of their transactions as are here alluded to, yet the results of the

Such fa the view of the value of the annual sick allowances, or rather of a
onntingent tmnulty, acc<»-ding to the rate of sidraess in each decade, as reported
to tbe Highland Society of Scotland, given by Mr Finlaison In his Beport to
the Select Committee of the House of Commons on Friendly Sodeties in
IS2B ; and be has aim given tbtIoub rules and tables Jbr ascertaining the re-
quldte contributions from members entering at any age to defray these at.
lowances, nmilar to those given previously in the appen^z tn the Highland
Society's Beport But as space will not admit of entering here into that pro-
cess of calculation, and as, at any rate. It would not perhaps be easily under-
stood by the class of readers fbr wbjch these observationB are intended, the
method adopted In the body of the Report of tbe Committee of the Highland
Bodety, which was considered simpler than that in the appendix shall alone
he adverted to.
The late of sldtnesa bedng iinind In the way already mentioned, and the
rate of mortality fVom an average of the Northampton, Swedish, and Carlisle
tables, it was calculated what L.i of annual contributions (or fifty years from

memben entering m societ; at 31 yew-gof age, would amount to with int«re*t,
when tba aurvivon anlred at the age of 70. Ud aba at thb deUh ttf the last
memlteri aadllkewiaewtwt L.l of weekly ilckallowauce paid to each of theae
tneatben during dckneM, wo.uld amount to with interest at ?0 ; also, what an
allowance itf L. 1 for each death would amount to with Interest, at the death
of the tact member. Frem comparing these, it was finind, 1st, that if each
inenUjer wne to paj an annual contribution of L.l, trom coDunencing his
Slat till concluding hU ^(Ml year of age, should he live so long, and then to
cease contributing, muA umual contribution would afford a weekly allowance
during mckneas&om 91 to 70, of L.1: ft: 7; Sd, that a like contribution would
■fibrd to each surriTing raembei, during li&, after bis 70th year, a life annui-
ty ar peraMUtent ^uu^ allowance of I,S8 : : 2} Sterling ; and, 3d, that a
lUce annual contributioa would a£Fard a sum p«yable at the death of each
member of 1.39 : 19 : 2.
In order to Illustrate these calculations, and to exhibit, in the simplest
fonn, a. view of the course of aflairs in a Friendly Society, it was rasolved to
" adopt the tuj^ioBltiint of a aodcty of pCTBons entering in the Slst year ot
tb^ sge, and continuing united till oU the mcmbn^ may be supposed [o be
dead, the iDdety M commence with 1006 peTsons, and to admit no future en-
trants. In tracing the progresa of tide society year by year, till all Its mem-
bers, according to the tahle of mortality, may be supposed to be deni, there
is saen the accumulation of its stock fbr a long period, then its diminution,
and at the death of the last member, lt« final extinction. Hence the means
ate given to draw coiSJurians applicable to all Friendly Societies at what-
ever age entrants are admitted; for the same terms of contribution and al-
lawanoe eakulated for a society which adntita no new members, are applicable
to a society which is continually recruited by new members of the age for
which the calculations are made, or to a Bocief:y adinittiiig members at later
ages, upon payment of a (oiiperfine orregolstlng payment,"" With a view,
also, t« accommodate the payments tp the circumstances of every individual,
the contributions were contemplated under three difierent aspects : " Ist, as
paid and accumulated uinually ; td, as supeneded by a single paymtst made
at the commencement of the sdieme, in lieu of all annual oantributi<mE ; and,
: 3d, as Biperseded at ai^ later age, between 20 and 70, by a un^ payment
Ihea made in lieu of all contribution afier such later age. -I''* As explanatory
«f these caltnilatioDE, uumemus tables and rubs we given for all the four
schemes, and from which there .njaj likewise he deduced, by the ordinaiy
rules of Propottion or Rule .«£ Three, the necessaiy coDtributions fbr any
other allowances than those therein assumed. As the tabular fona, however,
will illustrate to trdinary readers tjie operations of a Friendly Society more
distinct^ than any brief set of nilea which could here be given, we have
compiled the following tatile from those of the Slckiiesi Scheme given in the
Beport,

188 Mr W. Fraaer Oft Ae iUitorgi and ConttUtttioti qf
By tliifl taUe it vriU b« perceived, thU, with Uu! advwice of ige, the mem.

the eip«i4itiire.UoLfl.)-iacreBaea. It will be likewise perceived, however,
that when 4 per cent interert tcoL 6.) is added to the contributiona (coL 8.),
■ and also 4 per cent interest (coL II.) to the dlfltributions (col. 10.), and when
tlte totAl Btnount of the two iatler (col. 12.) ia deducted Ironi the amount of
the two fiirmer (coL 7->, a large balance (cols. 13. and 14.) will for many years
be left in&vour<rfthe aohfH-ing membere ;— that Ibis balance will accumulate
Bt first very rapidly, but afterwarda more slowly until the age of 64, when it
will b^n to decrwise »--that at the age of 71 (in the middle of which year of
see, both contributions and alhwancei for sickness were calculated to cease),
It will be wboUy exhausted j— and thst then both the amount (coL 7.) of the
contribution with interest, and the amount (col. 11.) of the distribution, with
Interest, will be found exactly to equal each other.
This society, it has been stated, ia supposed to have begun with lOOA man.
bers, all atthe commencement of Ibeir 3l8t year of age, or rather, owing to
the contributions and allowances being considered as payable at various times
in the year, with 1009 manbers, bring the average number alive in the swdifis
ofthat year ofage,-aud to have admitted no new entrants from its cnmmence-
ment till its termination i_circum»tance«, however, which are not likely ever
to occur in actual practice, and the conclutions msy therefore perhaps at first
right appear to be in^qiliiable to the q>enition8 of real societies. This large
number of members was assumed for the sake of avoiding the awkward and
unnatural appearance of firactional parts in the annual mortality, which would
necessarily have resulted, had a smaller number been taken ; and, with re.
said to no new members being supposed to be admitted, it will be obvious
that it matters not whether the oripnal entrants had remiuned the sole mem.
bera, or new ones been admitted at aU ages, provided each new member of a
hidierage than 21, had paid— either * sum equal to the stock which the ori.
gtnal membwB had in the sodety, after defiwying aU their allowances, when
Hiey arrived at his age,— ^)r adngle or increased annual contribution that
would ultimately amount to lt,.;-or should have only been entitled to a lower
ntc of allowance than the earlier entrant, making the same payment
For example, the standard annual contribution of the ori^nal members be-
ii^ L. I, and the weekly wck allowance L. 1 : : 7, when the society has been
tffli yeers in existence, and these members have reached the middle of their
Slst year ofage, they would then have a total capital of L. 4701.048 (Table,
CoL IS.) or L. S.SSU each (coL 14.), and this sum, it has been shewn, would,
along with thdr future contributions, be all required to defiray thdr future
allomnces. Now, a* a memb^ just entering at that age, has, with a very
slight difference (owing to his being then in health which some of the first
members may not now be), tlie same chances of rickness and death in time to
cmte, with the original entrants still alive,— and as iiis future contributions
are of less value (coL 16.) while hU future diatribuUons are of more value

(cot. 16.) to the Bodety than thej would have been at 31, — it in erldent, that,
to receive equal benefit with tbose tnembers who entered at that age, he should

' (al of each'of Uieseftindt.-' i < ~ ~
Jt may be premised, that the number of members stated to be annually
' alive in the Annuity and Funertd Schemes, Is somewhat different from that
pven In the Sickness Scheme. This arises fh>m the nuaiber alive la thb lat-
■,ter scheme being tatAiin the middle of the year, as was done by'the'CJom.
■'niiltee,oftheHlglilandSD6iety foraDtheschemtsi while here, thenulnber
'*)ive in tt)e Annuity and Funeral Schemes Is calculated for the h^;Jnning of
.each year, after the 3l*t year of age. This bu been doner wiUii^atd to the
IVmeral allowance, -to ' avoid t&e dlAre^ancy alluded tb in the note ^ p. SS3.
of the Report of the Highland Society, where it is said, " tliat the difi*erence
betwixt the result by the common mode of calculation, and the one adopted
- in the Report, is owing to tbe mftnBef In whidi the average number of Uving
throuf^out tlie year is taken, 1^ VUch it h^tpena that tlie number of deaths
la not always the exact iStFeteatx ttetween die BUccead.ve numt)erB of the 11>
Vlng." The efiect of this is to taUke tbe Indivlduia values less in the earlier
ages, and greater iii the higher ones. The following Tables, with these divi-
sors, were found among the-papeni of the late Mr Skirving, accountant, itKlch
have been kindly comniuuicated to us by bis widow.

It maj be mentioned, that the rapid accumulation of total and individual
capital which takes place in the Annuitj Scheme, not onlj arises from the an~
nual addition of Interest upon the capital, but aiao from the aurviving mem-
bers acqulrii^ right to both the contributions and accruing interest of those
who have died. The accumulation of capital in the Sickness Scheme is also
owing, in a certain degree, to the same cause ; hut in the Funeral Scheme,
tiie fluil is diminiBheil to the survivors \>y those who die in early life. The

h^er a^, or upon the number of ;rean whicb, Uking liTes of the aame

(mjojisg, — those who live bejond that period enjojing as much more, In
proportion to their number, as those who fail short of it eqjoy leva." It
will therefore be obvioue, that, as no disbuiBemeot ia made from the An-
ntlitj Scheme till each mrviTing member reachea the 71at year of hia age,
the capital of this fund must accumulate very rapidly for a number of yeara
after the commencement of the society, and that the niTvlvorg muH be
very great guneni by every death which has previously taken place. On
the other hand, it will likewiae be obvioua, that, as the djabursementa of
the Funeral Scheme are calculated to commence with the very initltutioD of
the Bocietj, the cajntal nf that fund must accumulate much more slowly,
and that a loss will be sustained to the society by Uiose who die early, which
must be again compeuMted by those who live to old age. Hence it follow*,
that, in the Annuity Sdteme, those who die soon are great losets, and those
who live long are a« much gainers ; while in the Funeral Scheme, ou the con.
trai7, the representatives of those who die early are gainers, and those who
Hve long are luserSf— the younger dan in this scheme receiving more than
they pay, and the older class paying mori! than they receive.
Sudi bring the nature of the operations of these two schemes, and to a
certain degree also of that for rickness, it would be of great advantage, both to
the members individually and to the society as a hod;, that, alongst with any
benefit during sickness or at death, there should likewise be aasured an annui^
in old age. In this way the members who should be &voured with long
health and Ufe, and consequently be losers by the sickness and ftineral
schemes, would be as great gainers by the annuity scheme t and Um society
would also be in a great measure protected against the admisdoa of bad Uvea
and premature allowances during sickness and at death, aa none such wonld
choose to pa; tOr an annnl^ which there was no probability of their ever en-
jDyii^. This comUnatlon of benefits, too, would greatly tend to diminMi
that spedea <^ ImpodtltHi so frequently pnctised upcai societies, of understs.
ting ages at entry, and which there is Grequently no possibUity of detecting t
for few insuring for an annuity would imderstate tlwdr ages for the purpose
of at first saving a trifle on their annual contributdona, wliile they would ulti-
mately run the risk of loss b; thrir annuity bring so much longer deferred.
Laying, therefore, entirely out of view the necessit; for providing for old
age, it will be seen that it is only by having an annuity combined with the
other benefits that a society will be safe from imposition, and that tlie mem.
bers themselves will be hum^ of an adequate return for their contributions
to the sickness and fiwend schemes.
It is trusted that enoo^ has now been stated to convince the members of
Friendly Societies tiuA the rales of both ddness and mortality are mudi lets
In the earlier than In the more advanced periods of life, and that the eontri-
buliona at the commencement must therefore be eithei greatly more than is
necessary at first to defray the allowances, or that Uie former must be Ineraaaed,

it is easy to nee, that the aggregate amount of the values of the individual

sumed law (of dckness or) mortality, or rate of interest upon vhlch the ratea
.of contributianlisTe been calculated, — will be always ei^uivalent to the smonnt
(f the gross fiind. The benefit assured to each individual is that according
tu which his contributions are made, and which he or his heiis or nomineea
will be entitled to clsim as ■ d^t upon the tiinds, whenever the event ar-
rives upon which it becomes payable, or, in other words, it is Ms share of

" After the society has existed for any time, the share of stock held by
eodi member, coniddered in relation to the mode of its being cmtributed,
maybe contemplated as conKUting of two parts, viz. .Avf, Hit than af A* find

tions; and, itoondlf. The value of hi* future oanMbuUoiu (col. tS.) The sum
of these two is evidently equal to the present value r^ his benefit assured
(col. 1(L> If it be said that, in estimating the value of the member's intarcsts,
his future contributions ought not to be taken into account, the answer is,
that they are as eSectusl); secured as any obligation In lavour of the Mciety,
because the non-payment voids the policy ; and, therefi»e, as welt in respect
to the individual as to the society, it is the same thing whether the stock con-
slita uf money paid down, and vested in securities granted by strangers, or in
the obligations of the members. In short, the benefit assured, modified by
the circumstances under which it is payable, may, to use a mercuitlie pbraw,
be considered as the amount due lo the member upon iiis ' aeeeunl in eoapamt,'
and his future contributions as the amount of what is due bg him upon hfa

I^ therefitre, a Friendly Society has proper tables, shewing the amount
of d^tal which It should be possessed of fbr eadi member at every age, ade-
quate with their fiiture contributlraiB to defray thdr fUtuie allowance*, and
if a proper record be kept of the number and ages of thoM insured far each
Iwnefii, it will be easy fin such a society to ascertain the re^ amoimt of cai^tal
which it should at any time be possessed of. For example, let it be supposed
that a society has existed Iot some length of time — Uiat the calculations ibr
the SUkDCM and Funeral Schemes have proceeded upon the same data as those

146 Mr W. Fraser on the History and Constitution of
The meUiod adopted in the fbiegolng table, however, vuuld not >lbi);elJiez
answer lor socieliea who admitted memben at all ages without an equalizing eu-
trj-monej, but merelj upon payment of an increased annual contribution. In
t&at case, one way of islculating the stock of each individual in the slcknesa
■cheme, for example, is aa fbllowa : —
It is wished to be kDown what litudt a societj riioutd be posaessed of for a
member who entered at 31 years of age, who is now 30, and who has paid the
Handard annual coDtribution of L. 1, in the interv^ ofThese ages.
The value of the future distributions to a member aged 30, (by the table,
[>. 136. coL IS.) is - - - L. 31.3011
If be entered at 21, and ia paying ui annual contribution of 1. 1,
the value at 30, (coL 16.) of his whole future umtributiona, ia 16.6944
And the difierence (coL 14.) is his slock or interest in that fund, of L 4.6067
AgUD, tt is wished to be known what diould be the stock for a member who
entered at 30 years of age, who is now 40, and who has paid the increased ann
Buat contribution of L. I.2TSS4 (coL 17) in the interval of these ages.
The value of the future diatributions (coL 16.> to a member -
aged 40, ia - . . - I,8«,M06
The value at 40 of a future payment of L. 1, (coL 16.) Is L. 14.0893
The annual contribution payable by a member enter-
ing at 30, (coL 17.) ia - - - l.37»»*
The one being multiplied by the other gives the value
of this member's future contribution at the age of 40,
which U ..... ia6278
And this last being subtracted from the value of bis future aUsw-
ances at that age, the difference, or his interest in the cajrital at
the age of 40, is ■ - - - 1. 7.M9B
Having, in this way, ascertained the estimated stock of each member at
every age in the society, and added the whole sums t'other, the total amount
would of course be the capital required.
But it is very probable that neither of the above methods may be entirely
a^Jkable to every. aociety, as the requisite amount of capital mast alwayn de-
pend, more or less, upon a variety of circnmstonces, with regard to the value of
the future contributions and allowances, which it is impossible here to enume-
rate or fbieaee, but which must be taken into account at the time of balancing.
Our olgect at present is not so much to give rules for performing these ope-
fations aa to shew their expediency ; and if societies <mi^ become convinced
tf the necessity of entering into periodical investigations of thdr afihirs, they
will have recourse far directions to some of the works on annuities *, or to per-
•ana pracllcally acquainted with the snlyect. It ia to be particulariy observed,
bewerer, that, In performing such operations, it will not do to take the average
age of off the members c^a society, and hence conclude that the rickness and
consequently the demands, wilt be the same as if each member were of that
age. For example, take one member at SS years of age, oae at 36, one at 46,

one at 5S, and one at 65, the avenge a^e of each pr these fire members will
then be 4ft, but tbeir average «Mn«n will be much more tbaii if each of them
had been in reality 4S jears of age. Thus, the average sickness of a member
at aSyearaofage, is 4 days 3 hours; of one at 35, 4 days 19 houru ; of one at
40, 1 week 4 houra; of oneat 55, 1 week 6 daya Shours; and of one at 6a, S
weeks 4 days 10 hours, being in all 9 weeks 6 days I hour; which being di-
vided among these five memhers, ^ve to each 1 week 2 days 6 hours, while
the average sickness to a member at 4ft ymra of age is only 1 week 4 hours,
OX about one-third less. This will shew how the sicknesB and clmms againat
a society may increase, although the averse age of the menAere, when taken
as a whole, may continue nearly the same for a long series of years.
It may only &rther be remained, with regard to fines and payments in ar.
rear, and calculated on above as stock, that such debts are really as beneficial
and secure as if the money were actually In the society's possession ; for tbey
must be either all pud within a limited time, and that, too. In general, with
hlf^ intecaat in the shape oF additional fines, or forfeiture of the whole [ȴ-
Tiinu pigments Is incurred. These debts are therefore equal to the same sum
In poasesaion, and as they will always form a con^derable part of a society's
ca^tal, the strictest attention would require to be paid to the book-keeping.
Indeed, it will be now obvious, from what has been stated, that this is at any
' rate indispennble, for no Friendly Society can ultimately succeed whose books
do not afford nteans of ascertaining the amount of the engagements to the
members by the society, and its ability or inability to meet them. Forvanr
BU^estions in this departifient, as well as for much useful information on other
matters connected with Health and Life Assurance, we have been indebted to
Mr James Cl^iom, accountant in Edinburgli, whose practical acquaint-
ance ¥rith all that relates to such sul^iects baa been likewise of the greatest
service to several sodeties lately established.
But highly important as proper books and periodical investigations are for
securing the permanency of societies and the due ftilfilment of their obliga.^
dons, such books and investigations are no less important in another point of
view. By th^ means members will be always made aware of their real inl«- .
rest at any age in the capital, and will thus often be prevented fitim allowing

Proceedings of the Justices of Ike Peace in the case* of Forfeited
Members of Friendlif Societies.
A few months ago there appeared In the newspapers the report of a suit'
raised by a Friendly Societv at Ellon, In the county of Aberdeen, agailst
-' ...Coodc
148 Mr W. Prflaer on the History and Constitution of
lome of itB meniben, for pajnneat of no less than fourteen yean alleged ar-
rears, and in which it was stated, that the circuit court, upon on appeal, had
decided againet the members to the extent of the first two years' dues, bejjig
the period during which they were entitled to benefit. For some considerable
time previous to thie decision, simUarcaseg had frequently occurred In the Jus.
Uceof Peace Courts, but the judgments were often so inconsistent and contra-
dictory, that no fixed rule of deduon could be sidd to e^ust, and prosecutions
were by no means generaL In consequence of the report of the above decision,
however, the question was considered to be settled in favour of the societies ;
and, therefore, several of these institutions in Edinburgh immediately came to
the resolution of demanding &om all who had been at any time connected vritli
them, payment of whatever sum appeared from the books to have been un.
pfdd at the time thej ceased to be members, and for the non-payment of which
they had suffered the stipulated penalty of expulsion and forfeiture of all pre-
vious ccHltributions to their respective societies.
Numerous prosecutions having next been threatened for non-compUance
with these demands, — which were c<msidered to be both iniquitous and ille-
gal, and which, if successfiil, would be productive of the most serious conse-
quences to great numbers of working people, — application was made for infor-
mation as to the particular grounds of dedsion on the circuit. From the infor-
mation thus obtained, it appeared that thecaseat Ellon bad been decided under
particular circumstances, and that it could not therefore be held as a precedent ;
■nd, at any rate, that the equitable principles of accounting appUcable to such
cases, had never in any question been taken into consideration, but that both
societies and judges had acted merely upon the principle, that as long as a
member is entitled to claim benefit, so long is a society entitled to compel
payment of his dues. It being evident that this general rule had been adopt-
ed and indiscriminately applied, without any regard to the pHrticulHr circum-
stances in which each society might be placed, — the conditions upon which
the members had entered, — the peculiar nature of societies' operations, — or to
their own printed r^ulations, — a case explajiatory of the whole was drawn
up and circulated among the gentlemen composing the Law Committee of the
Justices of the .Peace for the county of Edinburgh. In this statement it
was shewn. It/, That the contributions of members are always piud in ad-
vance ; 2d, That each member has always a greater interest in the stock than
any sum of contribution he is ever allowed to run in arrear, and hence that
every society is greatly benefited by each forfeiture that occurs ; Srf, That
such forfeiture was in general the only penalty for nun-payment, either sti-
pulated or enforced by the regulations or practice of Friendly Societies ; and,
Vh, That their former members could not therefore be now called upon, at
the distance of months and years, to pay what neither the one party nor the
other ever before conceived to be due. The Justices, however, stated,— upon
a special case being brought to try the question, and to which the above ob-
jections [larticulariy applied, — that they could not coincide with the state-
ments which bad been made, as they held, that when a man became a consti-
tuent member of a Friendly Society, his contributions could no longer be
considered his individual property ; that, as long as a member was entiUed to
b^efit, he was bound to pay all the Mated contributions ; and that having

Ibe decinon of a Judge of a supreme court before them, they cuulil not ilo
otherwise tbui take his opiniua as their guide.
The result of this case having also been made jmblic through the medium
of the newspajiem, prosecutions Immediately became general throughout the
whole of Scotland, but more especially in the capital and its vicinity. In the
Justice of Peace Court of Edinburgh, there were sometimes thirty and forty
such cases in a day ; and the extent of oppres^on and injustice to which these
measures led can hardly be imagined. Numbers of poor people, after having
contributed to these societies for a long series of years, became unable, in the
late distressing times, to continue their payments, and were consequently not
only forced to aucrcnder the whole that tbey had provided for sickness and
old age, but also subjected to imprisonment for non-payment of what waa called
arrears. Othen, again, who had contributed for as long a time from mere
tbelings of benevolence, who had never received, nor intended to receive, any
benefit, and who had left the sodeties fi^im inadvertence or otherwise, were
no w,dragged before these courts, and decerned against fur whatever sumswere
demanded as arrears. By the statute 6th Geo. IV. cap. 18, under which the
Justices act as a small debt court, it is ordered, that " a copy of the account,
document of debt, or state of the demand, shall be delivered by a constable or
peace-officer, to the defender personally, or left at his dwelling place;" and
in the very summonses issued from the Justice of Peace Court, there is the
following " N, B. The Justices strictly enforce the provision of the act which
requires a copy of the account, document of debt, or state of the demaud to
be delivered to the defender, at the time he is summoned." When such ac-
counts were called for, however, the act of Parliament produced, and the note
in the summons referred to, the court decided, in no fewer than six different
cases, that such objections were irivolous, and intimated that they were deter-
mined toenforce payment of these arrears, and to support Friendly Societies
by every means in thinr power, as they considered them most valuable insti-
tutions. But the defenders having threatened actions before the Supreme
Court, if these decisions were enforced, a farther hearing took place, and
several of the Justices at length b^an to express doubts of the equity of
such decisions. With regard to this particular society, it was found that
the question ought to have been tried in another court ; and the cases were
accordingly remitted to that of the city Magistrates ; but with regard to nu-
merous other cases, it was deemed prudent, in the mean lime, to delay decid-
ing them, until their merits should be farther considered, and proper advice
obtained. The city Ma^trates having followed the same course, tbe matter
remains for the present unsettled *.
Such, then, being the nature and supposed difficulties of these questions, it
is trusted that the following additional detail will not be considered as alto-
gether superfluous for their farther elucidation.
At the commencement of every Friendly Society, a number of individuals
agree to contribute each a sum as entry-money, and afterwards a quarterly
contribution for one, two,-three, or more years, before any of Ihem shall claim
or be entitled to benefit ; and should any one die or withdraw before the ex<

'50 Mr W. Fraser on (lie Hlslortf and Constitution of
[dralion of the stipulated tersi, all his contributions become the property of the
Mdetj. It a also agreed, that each member shall be allowed an indulgence
of fbur or five quaiters before he can be expelled for non-pajment ; and such
Doit-pajment has been uoifbnnly the onlj intimatioa ever ^ven or required.
Then any member intended or was obliged to leave the aocietj. These are
usually all the stipuUtions with regard to contributions, resignation, or espul-
sioa, and of course apply equally to the future as to the original memberB.
Before a member, thercfbre, can become free, or entitled to benefit, he
must have paid, besides entry-money, one, two, or three years' contributions
in advance ; and it is out of these, that the society afterwards de&ays the
allowances, in the first place, until tbey be again replaced, and generally more
than replaced, nith the interest uflhe remaining capital, and the future contri-
butions as each quaiter-day srriveB. (See table p. 136, cols. 13, U, &c) Should
any member fall to pay regularly, he is charged high interest, in the shape of
a fine, for each neglect, until the period of forieiture ( and should he Ml nek
or die before forfeiture, the arrears and interest are deducted off the first of
his allowances-
It will thus be seen that no society can ever run any risk uf loss by mem-
bers in arrear, it being out of the advajiced or past contributions thai all thtax
claims fall to be defVayed, — that the current contributions, or those in arrear,
are deducted by the society off the first of their allowances, should any such
be required, — and that, should a member be ultimately expelled for non-pay-
ment, the tosietj is much more than repaid, by retaining the whole of his
subscribed catnlal before be became tVee, together with his share of any accu-
mulation wbicfa may have aflerwards taVen place.
If any farther proof of the accuracy of these remarks were wanting than that
afforded, by the tables and explanatory observations onp. 136, efte;. we would
particularly refer to Mr Cockbum'e lucid statement, as quoted on p. 143-4.
It is said, however, that as a society has the risk of a member's sickness
and death during the period he is in arrear, so it is but equity ttiat he should
make payment of such arrears, and then, if he chooses, withdraw IVom the so-
ciety. In a propritlory assurance company, where the assured have no inte-
rest in the capital, were an insurer indulged with a delay in payment of bis
premium, at the same time that the company held themselves bound to him
during the interval in benefit, such a rule would be just ; but if^ on the other
hand, this same person held a share in the concern to a far greater amount
than the sum be fell in arrear, it would not surely be attempted, upon his
ultimate &ilure in payment, both to seize his capital, and also to prosecute
him fbr his premium. But this is exactly the course which is now proposed
to be adopted by Friendly Societies, fbr as these institutions are mutual as-
surance companies, every member has a share in the capital ; and before any
one can be entitled to claim benefit, liis share must exceed the amount of
any arrears which he can ever be due. This stock arises, as before stated,
first from his contributions before becoming free, and next from the progres-
sive increase of the fund. (Table, p. 13« & 140.) He, therefore, at the be-
ginning, advances money on the &ith of the society, while the society, on
the other hand, allows him to run In arrears on tbesecurily of his stockj and,
as already mentioned, a forfeiture of such stock is incurred, if these arrears
are not paid irithin a spedfied time.

tention and use of such societies, that some members shall receive much more
than others; and it will not surely be pretaided, that, without tome apedal
agreement, those on whom sickness has &lleu would not have the same right,
ages and payments alone being considered, to an equal share of the stock, i»
the event of a subsequent division, as those who had never rec^ved a &ctUllg.

<in the old Bodetles at least), so Ibng as they are connected with the instl-
tution, and as Uie managers cui always retain payment of all arreaTB off the
allowances in the event of sickness or death, a society, even in this pdnt <£
view, runs no greater risk with a member in arrear, tlian with one who li not.
Every Society, tberefiwe, is grertly benefited by every surrender or i(«lbi-
ture tliat occurs ; and this is so well known by all the higher classes of Hu.
tual Assurance Associations, thai very considerable benefits are always calcu-
lated upon, and do arise, from such forfeitures, although with them no entry-
money, and only iu year's contribution, is paid in advance-
But, &rtber, the practice of retaining all the stock of a member who wisfaea
or is obliged to withdraw, has been even acknowledged by the more respect-
able assurance aasociattans to be uqjust ; and, accordio^y, the greats; num-
ber of tbem are now in the habit of purchasing the polkies (i. e. retumii^ so
much of the past coatributious) of such members as may find it inconveniant
or unnecessary to remain any longer In the institution.
In the Beport, too, of the Hi^land Society, while it is stated that for&ituia
appear to be indispensable in Friendly Societies, being the only practicaUe
means of enforcing rt^lar payments of small contributions, it is added, ** were
Friendly Societies once established upon correct principles, and accustomed te
ascertain perlodicaUy the value of the individual stock of their members, it
might deserve consideration whether it would be expedient tliat the diractMB
should have a discretionary power to purchase up, underaome regulated abate-
ment, the interest of members who are going abroad, or who have becmne
permanently established at such a distimce as renders inconvenient the maiis
tenance of thdr accustomed reJatlons with the socie^. An arrai^ement irf
this kind would obviate a general objection which frequently leads young
men to pottptme to a more advanced age their entering into aoclel^*."
Several Frioidly SodeUes lately oi;ganizcd have accordingly adopted this
r^ulation. Herlot's Benefit Sodety, for example, (whoae rules ware sane-
UtMied by the Qoarter-Bessions of the Peace for the county of Edinhui^
Slst November 1836), give a table, shewing the pecuniary interest of each
member at evoy age in the society ; which is ibr one at thirty !.• 3 : 5 1 1 ;
at forty, L. 8 1 8 : 6 ; at fifty, L.14iie:ft, ftci and, should circumstances rea-
der it necessary for any one to leave Scotland, he may either contittue a
member, or, upcm relinquishing all fiiture claim, receive threeJburtlis of his
stock at the time, after deducting all arrears.

their r^ulations, thai, if anj member satiEfj the committee that he ia tuuSJV
to Eonlinue his cuntributioiis, or Is about to leave Scotland, and wUbei on that
account to dissolve his connection wltb the Societj, " the committee ihall
be authorized lo purchase the interest of anj such member for a sum not ex-
ceeding two-thiids of the value thereof, according to the age of the party at
the time, the state of the Aiudi at the last period of investigntioD, and the
tablra of the SocietT." For example, an individual who entered at 31 yean
of age, and who has two shares in the Sickness Fund, three tn the Annuity,
and five in the Life Assurance or Funeral Fund (the annual contributims
being payable till the age of 6S), wilU at the age of 36, have an interest in
the stock of the society to the extent of Ii.34 : 16: 10 j, and should he then
withdraw, under either of the above circumstances, he will be entitled
to two-thirds of thie sum, after deduction of arrears.
But, supposing that no part of the capital were to be returned by either
of these societies tu niembers unable tn continue their payments, would it not
be must iniquitous to prosecute, alter forfeiture, 6uch members for arrears,
while there had been confessedly retained by the society a sum more than
equal to air times the amount P Now, although old societies have no books or
tables by which they can exhibit tbe interest of their members so clearly as
the abnve two 8odetie>^ yet it may, to a certain extent, be shewn otherwise ;
and the case of the society already alluded to, as having been brought before
t^ Justices to try the question of arrears, may be taken as an illustration.
This society was instituted in 1750; and by the last edition of its articles,
printed in 18S2, a man entering at the age of 31, would pay, before the socie-
ty ran any risk with him, entry.money, L.Jj r^ular contributions for three
years at is. 6d. per quarter, L. 1, lOs. ; six funerals annually ■ (the average
for some years) at ed. each, fbr three years, 93. ; fines, gay at least Is. : in all,
L. 4. Here, then, the advanced capital of this member is no less than Iw 4
sterling, besides interest, at the end of three years ; and this sum ought also
to increase, by the unappropriated balances of the subsequent contribuUons
and accruing interest, fbr at least ten years afUrwanls. But supposing this
member, from want of employmait, or any other cause, to run in arrear du-
ring the tburth year, — to be unable to pay within the limited period, — and to
be expelled tor non-payment of L. I, — would it not only be excesuvdy unjust,
but cruel in the extreme, to oppress him for payment of this sum also, while
he had been obliged lo surrender fbur times the amount ? And supposing
that he had fiiUen sick or died while in arrear, the society could in oo poud-
Ue view have been in a worse situation with him than if he had paid his dues
at the previous quarter day ; since, as formerly remarked, they had his past
contributions in their own hands, and also the power of retaining his arrean
off the first of the allowances. Above all, had this member t>een struck off
the roll tor non-payment, before he became Itee, but afler he had paid his
entry-money, and periiaps eighteen months' contributions, upon what pre-
tence could the society prosecute him for arrears, while tbey held these sums
in their possession, and bad never in any shape been liable to him in baiefit?

But without entering moie into detail as to the equitj of the case, it maj>
be remarked in geneml, that were it an established rule of amy society, that
members could only resign by written intimation, and upon paying all arrears,
tt would be proper, whether such law was equitable or not, that all should be
made to comply with it, until regularly altered. But where no such regula-
Ijon has at any time existed, and where the only notice of resignation ever
given or required, during a long series of years, has been that of non-payment,
surely no society ought to be authoiized tu enact, or at least to enforce, a law,
which is not only to operate against members in liiture, but also against persona
who have ceased — and some of them for many years ceaaed — to have any voice
or interest in its concerns. It is a well known maiim, that practice is held
to explain any law already enacted, and that every new law can only have a
prospective not retrosjieotive effect, without the consent of ali interested.
In short, if questions i>etween Friendly Societies and their members are
not to be decided by their own regulations and practice, all their calculationa

0« ifte Velocity ^ Sound. In a Letter from G-Ton Moi.L,
F. R. S., Professor of Natural Philosophy in the University
of Utrecht, to Professor Jah£son.
XN the Number for October of your valuable Journal, Mr H.
Meikle notices the observations on velocity of sound, which were
made by Mr Van Beek and myself, and an account of which
was published in the PbiiosojJiical Transactions of 18^ Mr
Meikle very justly states his apprehenuon that some of these
observations are erroneously mentioaed, as having been made in
January instead of June.
On receiving your Journal, I immediately turned to the
Transactions, and found, to my no small mortification, that
Mr Meikle is perfectly correct. The error which be points out
really exists in the Transactions, by whose fault I am unable to
tell. Whether I, or the printer, is guilty, is impossible for me
to investigate. If the fault lies with me, I cannot plead in ex-
cuse the cause which Mr Meikle kindly suggests. Il cannot
have arisen out cS ignorance of the language, ance Jum/ and
January belong alike to both idioms. It is therefore a blunder ;
and I must request you to correct the e^ct of it as much as
posmble, by infonning both Mr Meikle and the public, that all
the experiments alluded to were niade in June, and none in
Jamuuy.
If I were in possesnon of the apparatus pmnted out by your,
able correspondent, I should be very anxious to try its efficiency ;
and if Mr Meikle has had one made, I should be very much
obliged to that gentleman for the information where a similar
MK- could be procured. I am, &c.

Mr Meikle apprehends that the cause why the interval was
longer in the experiments of S5th June, than the mean of both
directions on the S7th and S8th, must lie in the difference of the
guns, or of the mode <£ charing and firing them. In turning
to tibe diary of these observatioos, I god that the 35th, S7th,
On the VelocUy <f Sound. 165
ami S8th of June, the long metal twelve-pounders have been
used OR both stations, loaded with six pounds of gunpowder.
The cartridges had been carefully prepared by Sergeant- Major,
now Captain or Lieutenant Essen ? ; the gunpowder, if not
from the sanie barrel, was from the same magazine. The
propriety of trying its strength did not then occur to us. The
guns were constantly discharged, loaded, primed, and managed,
by the same persons, either non-commisMoned officers or cadets.
The cartridge-bags were of -fustian, and not of paper. Instead of
wadding, a sod was rammed down on the charge as strongly as
poe»ble. I cannot therefore see any of the differences pointed
out by Mr Meikle. I had the observations of Captain Parry
and Lieutenant Foster in high latitudes, and low temperature,
reduced to the same pressure and temperature with our own
experiments. The results agree strikingly : an account of this
will be shortly published in the Transactions.
Mr Mbikle, in reply to this communication, has sent us the
following remarks.
With regard to tbe propooed appsratiM, it hat not yet been con-
structed ; bat I have bad some correapontlence with Proressor Moll on
die subject, and It is probable that an arrangement will be made for
(blowing tip the scheme; npecnaHy at 1 hare ei^^;ested some ma-
terial NmpIt6cations on tbe Atfginal pn^MMi^ — putleolBriy that, instead
(rf'pkfjng nob an apparaVas or dofk, at each end of the range,
it would be preCenMe to hare onty one in the middle, or somewhere
DO tbe line between die (riHerrers. By this menu, the ear wonM not
be ao overpowered by tbe prodigiensly loader «nmd of the bell beside
it, dun of that it was meant to bear. By placing obeerrers, too, on
opponte ndea of the machine, both in die line of 'the direction of die
(rind, and tdaa in anodier at right angles to it, tbe effect of tbe wind
eould be ascertmned ; and that, perhaps, even when the sound coiHd
not be beard to windward ; — a method whic^, fer several reasons, conld
scarcely be niflde'avwlable in the case of Ctmnon.
As to the conjectures, which I formerly tfareir out, to account for -
some slight anomalies in Prefessor Moll's experiments, it iwtot oe-
curred to me that t^e two guns, so judiciottsly employed' by that ^-
dngnisbed pbilosopber and bis sble associates, were snCb as woildd ei-
ther be accounted of different sizes, or reckoned to be differently

crepandes in their dinMnsioni, and in the modes of operating peculiar
to different indiriddftls. For, though Dr Moll says the guns were con-
Btantlf <liacharged, loaded, ftc by the same persona, yet he must mean
only the BSme rank or description of persons — not the same individuals ;
becanse the guns were fully nine miles from each other, and dischat^ed
nearly at the same time. Besides, if the sods, strongly rammed down
instead of wadding, presented the same resistaQce to the powder in
both gnna, I should rather deem it an accidental coincidence. At the
same lime, I am perfectly ready to admit, that I do not see how the
mode of experimenting with gnne could have been better managed than
was done by Dr Moll and his associates; and I consider their results
among the most valuable we possess.
In experimenting with cannon over great ranges, the intensity or
loudness of the sound must at first be very great, and then gradually
decrease toward the ferther end of the range, where it has in some in-
stances been so faint as to be quite inaudible, when opposed by a very
slight wind. But since the results so obtuned are only the mean of the
velocities over the whole range, they throw no light on the qaestion,
whether, or how far, loudness affects the velocity. It is, besides, high-
ly probable, that such a mean velocity from cannon may often happen
nearly to agree with the mean from a bell, and yet, for all thai, sound
be really moving with a retarded velocity, or slower as it gets fainter.
If, during experiments with cannon, additional observations were made
eomewbete intermediate between the extremities of the range, poaaibly
a solution of the question might, *■> ^ certEuo extent, be obtained, by
comparing the tiroes with the corresponding portions of the range. But
die difficulty of measuring these minnte intervals of eltpaed time with
sufficient exactness would here come into pUy, unless eomething like
the ^>par«tnB f(»merly suf^^ted were adopted. By means of that me-
thod, the nuDute intervals may be ascartuned with snch facility, that
■evenl observras could be raided at varione distances from die sonorous
body, which could scarcely bil to shew whether tbe velocity be uni-
form or retarded.
Guns with percussion locks, it is true, could be set off in succession,
by means of clock-work ; bnt it would be nearly impossible to make
one and the same gun fire at sufficiently short equal intervala ; and I
iMher doubt if two guns be often of precisely equal dimensions. To be
Hire, this might be examined and rectified if necessary, thou^ not
without considerable trouble. However, granting that any inequality
tiS uze were obviated, or did not exist, a more insuperable uncertainty
remains ; for we cannot be sure that two charges, even those naed anc-

ceaurely in the aame gun, are bo perfectly alike, so equally igoited, aoil
80 equally resisted by the wadding, or nbat«ver ebe is nsed for the
putpose, as to give extctly equd reports. It is true, that, in the late
experimeaia in France, the Telocity of sound was tbe same, whether
two or three pounds of powder were used ; but where powder has no-
thing to propel, a great part, especially of a larger charge, escapes
unbumt. For such reasons, the method of striking a bell at short
equal intervals by clock-work, though confined to a smaller range, pOB~
sesses a precision of principle which can scarcely be looked for with guns.
Perhaps to the sources of acceleration formerly suggested, should be
added, the sudden gust of wind caused by tbe great burst of flame, &c.
from the mouth of the piece. H. M.
Some Remarks Ofi the Bushmen of Orange River. By Louis
Leslie, Esq. Assistant Surgeon, 45th Regiment. Com-
municated by Sir James M'Grigob, Director-General of
the Army Medical Board.
-L HE military post at Orange River being abandoned, the
same opportunities may not again be afforded to another, of ob-
serving the manners of the Busiimen, and giving to the Medical
Board some account of their poisoned arrows. In that neigfa.
bourhood, and along the Hornberg P, purer examples of that ex-
U-aordinary race are perhaps nowhere to be found ; and whatever
follows, regards only them, and may differ from any accoimt of
other portions of the tribe along the African frontier. Small in
stature as the Hottentot race is, they arc, in the quarter' men-
tJoned, less than any where else, seldom exceeding live feet, but
cS the raosX. perfect symmetry ; they are active in their tnove-
m^its, but indolent in disposition ; their colour is dark, but is
rendered still darker by filth ; tbdr features are peculiarly for-
bidding, on account of the great distortion of the bones of the
face ; and the facial angle approaches considerably to that of tbe
monkey. The Bushman will seldom submit to coercion and
restraint, — if he does, he becomes the Boor's most wretched me-
nial, and perhaps is worse treated than any slave in the world. In
the state of liberty, they dwell in craals, under the authority of a
chief, whose rank is among them hereditary. The numbor in one
craal seldom exceeds thirty— men, women, and children. Tb^r
158 Mr Louis Leslie's RemarJea oh the
dwellings are formed of mats, if in the fUmn, just large eooHgii
to creep into ; but they often reside in a high and ridgy moun-
tain, under some projecting ledge of rock, the approach to wlticli
is narrow and difficult. If attacked there, they seldom flee. They
have no fear of death ; and, if possessed of a more powerful wea-
pon, might defy the attacks of the Boors, make them less IVe-
quent, and more fatal. Nothing but the privations they suffer
would make any one of them submit to the cruelty of the far-
mers; and, living as they do on locusts, ants, and some &in-
naceous roots, there can be no better proof of the insufficiency
of tbeir dny bow, and of the general inertness of their celebrated
poison ; yet they are themselves impressed with the conviclion
of its strength, and they have been able to impress their enemies
with a dread of its effects, if not of its fatality. I have never been
able to procure oae well authenticated relation of death produced
by it in man. I have known some cases of horses and d<^
dying from the insertion of the arrow into the leg ; but some of
them seemed to die rather from the effect of violent inflammation
in the limb, than Irom any specific power in the poison itself.
In cue instance of a dog, howev«, the animal became stupid
and inscnsilde in a few minutes, end died in twenty. Some co-
looisti who have been wounded, assert that they are subject to
periodical attacks of insanity, under certain states of atmosphe-
rical influence; but I believe this to be, like most of their tales,
quite unworthy of credit. The poison of the Bushman of the
Hm^berg ? is extracted from plants, and from [dants only, so far
aa I have been able to learn. In that quarter, they use no mi-
neral poison, nor the venom of snakes. Two q>ecimensof jdante
used by them accompany this ; the bulb is a species ot the
Hamanihug ; but never having seen the other plant in flower,
I have been unable to leam its name. Its leaf exudes a milky
juice, and, cut up and bcHled, forms a tenacious extract, which is
spread upon the arrow, to some thickness. There is another
(rfant which they use likewise, either above or with the other
two ; which, bother, forms the strongest they jvocure ; its mune
is " mountun poison." Growing on the stony hiUs, and very
rarely to be found, I have never got a apecimm of it.
Their dexterity in the use of their bow is remarkable, and the
distance they can shoot, with such a light arrow, is astoniAiBg.
Bushmen of Orange Biver, 150
't'bey will throw the arrow upwards of an faundFed yards, and
with great correctness ; but, as might be expected, it will st^dom
wound at such a distance ; and I have known a cavalry cloak
protect a soldier at twenty paces. The bow is not brought to
the eye in shooting. They fix their eye upon the object, grasp-
ing the bow with the left hand, while the arrow passes through
the fingers on the right nde, — a mode of shooting I believe
peculiar to them.
Their treatment of a wound made by a pmsoncd arrow is
truly scientific. It is hud freely open, the poison cleaned out,
and a horn applied in the manner of a cupping-glass, exhausted
l^ siicbon at the small extremity. This, as far as I could learn,
is the only treatment they adopt, never making' use of any herb
as a spetnfic The Boors consider gunpowder and urine as very
efficient, and prescnbe those in every arrow wound, and in every
case of snake-lHte. Cupjnng would seem to be the Bushmen's
favourite treatment of every complunt accompanied with p^,
and so frequently do they resort to this, that by the time they
are full grown they appear scars all over.
The length of time a Bushman can live without food is sur-
jMising, often living for three and four days without a mouth-
ful ; and the quantity they can devour after such abstinence is
equally remarkable, one man having been known to eat an Af-
rican sheep (30 lb.) in a ^ngle nighl. When unable to pro-
cure food, a belt round the body is tightened as the craving in-
creases, and they resort to the smoking of dakica (a species of
chanvre, or hemp), which produces intoxication. The narcotic
efifects <^ this plant no doubt fxoduce much of that shrivelled
appearance which is observable in all of any age. When posseft-
fflng plenty of their daidca, they can anoke and sleep for several
days and nights without eating.
A Bushman has no idea of the perpetuation <^ property ; I
might say, no notions of a prospective existence^ He is wholly
dependent on nature or on man : he will nether imitate the
Caffer new the Boor, will neith^ grow ccffn nor breed cattle.
The figures drawn 1^ them on the rocks are often remarkable
for the correctness of the outlines; they hit the attitude of the
animal, but seldom care about truth in colmiring : speaking phre>
Qolc^cally, they have the organ of fonn, but not of colour. I

liavc never seen aay animal resembling the unicorn among their
puntings, but such an animal is aaid to exist beyond the Orange
River. They are fond of music and dancing, but their musical
instrument is rude, and without power or variety, consisting cS
one string stretched upon s bow, whose vibrations are produced
by the breath, with great exertion.
The Bushman's conception of a Supreme Being is, that he is
an evil deity, and their notion of futurity, that there will be an
eternity of darkness, in which they will live for ever, and feed
on grass alone. They imagine that the sun sends rain, and
when he is clouded, they hold up burning wood, in token of dis-
approbation. They believe that the sun and moon will disap-
pear, to produce the darkness they anticipate.
The Budimau's bow is made of a peculiar tree, called the
Blue Bud), whose branches are^ almost moulded by nature to
the artificial form. The sinews of the quagga yield power-
ful bow-strings, and the arrow is formed of a slender reed, head-
ed with antelope''s horn, and pointed with a small triangular
piece of metal, which they procure from the CaSers.
(Nervations on the Structure qf the Heart g/" Jnimah of the
genus Rana. By John Davy, M. D., F. B. S. Communi-
cated by Sir James M'^Gkigob, Director-General of tJie
Army Medical Board.
XT is commonly asserted by the highest authwities in compa-
rative anatomy, and generally believed, th^ the animals be-
lon^Dg to the genus Raoa, and indeed all the animals included
in the natural order ' Batraciens' of M. Cuvier, have a single
hetut like fishes, composed of one auricle only and one ventricle.
Many observations which I have made on the common toad,
have led me to a different conclusion, and have sRtjsfied me to
demonstration that the heart of this animal has two auricles.
This structure is displayed without much diflicully by minute
dissection. It is best exhibited by making a transverse incision
into the ventricle, close to its base, and inflating the cavities with
the blowfnpe. In this way, and using fine probes, it may be

demonetrated clearly that the heart has two auricles, divided hy
a tran^jarent membraoous septum, possessing fibres that appear
to be muscular; that these auricles communicate with the ven-
tricle by a common and very short passage, provided with three
semilunar valves ; and that they have no pos^ble communication
with each other, excepting through the passage above the valves
common to both of tliem.
The same fact as to structure may also be demonstrated, by
blowing air through either of the two pulmonary veins, which
return the blood from the lungs to the heart. The pulmonic
auricle, the smallest of the two, is thus distended, and not the
systemic ; or, by blowing air into the large sinuses into which
the vense cavse terminate, when the reverse of the preceding ex-
periment takes place ; and this, at the same time, shews that the
margin of the septum acts as a valve, and must prevent the
blood of one auricle passing into the other.
But, even did not the margin of the septum perform the func-
tion of a valve, the blood from one auricle could not pass into
the other, the contraction of the two l)eiiig synchronous; the
auricles first contracting, next the body of the ventricle, and,
lastly, that part of the ventricle of a conical sliape, which may
be conudered almost as a second ventricle *.
I have observed the same kind of structure of heart in the
hull-frog and the common frog. Whether it exists in all the
other spedes of the genus, I have not ascertained, but most
probably it does ; and, reasoning from analogy, the probability
is very strong thai ^1 the other genera of the order ' Batraciens'
have a amilar conformation, both of this vital organ and of the
■ I am almost induced to consider this part as a »econd ventricle, &om its
pecuUiritieB, which I ant not aware have liitherto be«i noticed. It ia sepa-
rated fVonv the body of the ventricle bj' three valves, of a semilunar fbrm.
To the siAe of its cavitj is attached a flesh; projection, or moveable septum,
above which it gives orif^n to four arterial trunks, viz. two aortte aild two
pulmonary arteries, the tanner considerably lai^r than the latter, each pro-
vided with its own semilunar valve; and the action of this part seems to me
to be as peculiar as its structure. When I have watched it, it did not appear
to contract simultaneously, but first one-half and then the other ; as if in-
tended, in conjunction with the various anastomoses of the arterial system, to
preserve a conttant, though small, current of blood, to supply all the parts of
the body according tu their various demands.

Notice in regard to the Jactdaior Fitk of Java, or Chatodoii
rostratam, Lin. By Jahks Mxtcheii., Esq. Surgeon,
A. N. Communicated by the Author.
tV hilst residing in the Island of Java, in December 18SS, I
heard of an extraordinary species of iish, in the possession of
a Javanese Chief, who lived within a mile of the town of Ba-
tavia.
Accordingly I went to see it, in company with Mr John-
son, the cMmnander of the ship Guildford, in which I was a
passenger, and with an interpreter.
On our arrival at the chief's villa, we were treated by him
with great courtesy. After converGong with him some time he
permitted us to visit his gardens to see these fish, upon which
he placed a high value, and would on no account part with one
of them.
The fish were placed in a small circular pond, from the centre
of which prcgected a pole upwards of two feet in height. At
the top of this pole were inserted small pieces of wood, sharp
pointed, and on each of these were placed insects of the beeUe
tribe. The placing of this pole and insects by the slaves had
disturbed the tranquillity of the fish, so we bad to w^t some coo-
aiderable time before they b^an tb^r (^>erationB ; but this da,
lay was amjdy recompensed by the amusement they afla-wnrdt
afibrded UE. When all had been tranquil for a long time, they

came out of their holes, and swam round and round the pond.
One (^'them came to the surface of the water, rested there, and
after steadily fixing its eyes for some time on an insect, it dis-
diarged from its mouth a small quantity of wat^y fluid, with
such force and predsicm of aim, as to force it <^ the twig into
the water, and in an instant swallowed it.
After this another fish came and performed a similar feat, and
was fcJlowed by the others, till they had secured all the insects.
I observed, that, i f a fish failed in brining down its prey ait the
ficst shot, that it swam- round the pc»id, till it came oppo^te to
the same object, and fired again. In one instance I observed
one of these animals return three times to the attack b^ore it
secured its prey ; but, in general, they seemed to be expert gun-
WEB, brining down their prey at the first shot.
I was informed that these fish were originally imported ixota
China, and are now the only specimena alive in Java, although,
about fifty years ago, they were in possession of several of the
Javaoew clue&. I could not learn thcii; proper name ; the on-
ly one that I heard was the u^ual tern» for fish made use of by
the Javanese, viz. * Icon.'
From the view we had of them, which was only in the
water, they appeared ahtftt, about five or ^x inches in length,
nUba- tlait ia th^ body, with bL^ckisb stripes variously inter-
spersed.
The slaves of this chief fed the fish with insects regularly
twice 9 day in the manner I have described.
This appears to me a novel species of instinct implanted into
these animals by the wise Author of Natitte» enabling thiem to
secure their prey, by shooting in this manner those taseots thttt
should happen to rest on any of the aquatic plants growing in
tjie poods th^ iohabitj a,nd placed by their height out of their
i>eaoh.
When they eject the water from th«F mouths, it is oUended
by a noise like one spitting or squirting with a syringe.
As I hwd no opportunity of examining these fi^fa, I could not
say whether the fluid they squirted tsom their mouths was the
product t>f secretion, or merely the water fiK»n the pond*.

On
JN the 12th May 1828, M. Julia Fontenelle read, in the
academy of sciences at Paris, a memoir entitled, Recherckea
Chimiques el Medicales aur lea Combustions Humaines Spon-
tmUes.
The observatioDs which form the subject of this memoir are
highly deserving of attention. In fact, beudes the interest
extract &om the letter : " Governor Hommell * gives the fbllowuig account
of the jaculitor or shooting-fish, a nitne Blluiliiig to its nature. It ftequeats
the ahorea and mdes of the sea and rivere in search of food. When it spies a
tly diting on the plants that grow in shallow water, it swims on to the dis-
tsoce of four, five, or aji feet, and then, with a surprising dexteritj, it gects
out uf its tubular mouth a single drop of water, which oever bits gtrikiogithe
fly into the sea, where it soon becomes its prey-
" The relation of this uncommon action of this cunning fish raised the gover-
nor's curiosity; though it came well attested, yet he was determined, if possi-
ble, tu be convinced of the truth, by ocular demonstration.
" For that purpose, he ordered a large wide tun to be filled with sea-water ;
then had some of the^ie fish caught, and put Into it, which was changed every
other day. In a while they seemed reconciled to thrir confinement ; then he
determined to try the experiment.
" A_slencler stick, with a fiypluned on at its end, was placed in such a tUrec-
tion, on the aide of the vessel, as the fish should strike it.
" It was with inexpressible delight that he dally saw these fish exerciaiiig
their skill in shaotiDg at the fiy with an amazing velocity, and never missed
the mark."
Then fbUova Unneus's description, taken from his work of the Museum
of the King of Sweden, printed in 17S4, where it bears the name of CAafodon
In voL Ivi. p. 18S, there is abrther account of the habits of this fish, in a
lett«r ftom Mr Hommel : " When the jaculator fish," he says, " intends to
catch a fly, or any other insect, which is seen at a distance, it apprracbes very
slowly and cautiously, and comes, as much as possible, perpendicularly under
the otgect : then, the body being put in an olilique position, and the mouth
and eyes bong near the- surfact of the water, the jaculator stays a moment
quite immoveable, having its eyes directly fixed on the insect, and then
Im^b to skooi, without ever shewing its mouth above the aur&ce of the
water, out uf which the single drop, shot at the object, seems to rise. No
more than two difierent species of this fish are found here." The first is that
already mentioned, as described by Linnieus under the name Ciictodon roa.
tratum, and to which all the above refers. The other is described by Dr
Pallas, under the name of SMinu^mifaM*, p. 187 of the same volume. Both
species are figured — Ediiob.

which they are capable of exciting from their very nature, they
afford a new example of one of those phenomena, the existence
of which has, in these later times, been questioned, solely be-
cause, while they are very «ngukr and difficult to be accouDted
for, they are also of such rare occurrence, that they can only be
authenticated by an aggregate mass of evidence, which evidence,
although sufficient to induce conviction, may always be reject- -
ed by those who are prejudiced, or who do not give themselves
the trouble of duly estimating their value.
Are there really spontaneous combustions of the human body ?
Such is the first question which the author examines, and he re-
solves it by the affirmative. Fifteen observations of spontane-
ous combustions, which he successively relates, enable him not
only to establish the incontestible reality of the phenomenon,
but also to make known the principal circumstances which ac-
company its manifestation. In summing up these circumstan-
ces, he remarks :
1. That persons, who have been destroyed by spontaneous
combustion, have, for the mOst part, been immoderately addict-
ed to the use of spirituous liquors.
S. That this combustion is almost always general, but that it
may be only partial.
3. That it is much rarer in men than in women, and that the
women in which it has been manifested, have almost all been
aged ; one woman only was seventeen years of age, and in her
Uie combustion was but partial.
4. That the body and viscera have always been burnt, while
the feet, the hands, and the top of the head, have almost always
escaped.
5. Although it is demonstrated that several loads of wood are
necessary for reducing a dead body to ashes by ordinary com-
bustion, incineration is effected in spontaneous combustions with-
out the most combustible objects placed in the vicinity being
burnt. In one case there was a very singular coincidence of
two persons being consumed at the same time, in the same apart-
ment, without the apartment or the furniture being burnt.
6. It is not demonstrated that the presence of a burning
body is necessary for prcxlucing spontaneous combustion of the
human body ; on the contrary there is every reason to believe
the reverse.
1^ On the Spantaneout Cambuatioa ofUte Human Boc^.
7- Water, so far from extinguishing the flame, seems to
render it more active ^ and after the flmne has disappeared, the
intimate combustion continues to be effected.
8. Spontaneous combustions have appeared more frequently
in winter than in summer.
9- No remedy has been found for general combustion, but
only for parUal.
30. Those who undergo spontaneous combuBtio>n, are the prey
of a violent internal heat.
11. Spontaneous combustion developes itself suddenly, and
consumes the body in a few hours.
12. The parts of the body which are not consumed by it, are
attacked with sphaoelus.
13. In individuals affected by 'q)ontaneouB combustion, there
supervenes a putrid deteriora^on, which presently brii^ on
gangrene.
14. The residuum of spontaneous combustion consists of greasy
a^es, and an unctuous soot, both having a fetid odour, which
(Uffuses itself equally through the t^uutment, imprecating the
furniture, and extending to a great distance.
The author then explains the two theories of combustion be-
tween which the learned world is at present divided ; Lavoisier's,
and that lately proposed by Berzelius. He then gives an ac-
coimt of the theories proposed for the ex.planat!on of the pheno-
menon in question.
Most authors, who have spoken of spontaneous combustions,
have imagined they discovered an intimate relation between their
manifestation and the immoderate use of spirituous liquors in
the individuals attacked. They suppose that these Jiquors, be-
ing continually in contact with the stomach, penetrate through
the tissues, and fill them up to saturalJCHi, in such a manner that
the approach of a burmng body is sufficient to induce com^bus-
tion in them.
M. Julia Fontenelle does not condder this explanation satis-
factory. He founds his opinion, 1st, On the circumstance that
there is no proof of this alleged saturation of the organs in ,per-
Bons addicted to the use of spirits ; ^ly, On the circumstwice
tiutt this saturation itself would not suffice to render the body
combustible, — and, to demonstrate this assertion, he gives the
D.n.iized by Google
On ihe Sponioneous Comimition of the Suman Body. l67
result of several experiments, in which he in vain tried to len-
<der ox-flesh inflammable by ateepii^ it for several months in
brandy, and even in alcohol and ether.
Another explanation has been proposed. Ur Marc, and with
him several other physicians, Irom the development of hydro-
gen gas which takes place in greater or less quantity in the in-
testines, have been led to imagine that a similar development
may take place in other parts of the body, and tliat the gas
might take fire on the approach of a burning body, m: by go
electrical acti<m produced by the electric fluid, whioh might be
developed in the individuals thus burnt. According to this
tbemy, MM. Lecat, Kopp, and Marc, gu|^se, in subjects af-
fected by spontaneous combustion, 1. An idio-electric state; &
The development of hydrogen gas ; 3. Its accumulatioti in the
eellul&r tissue.
This latter explanation would appear to be confirmed by a
very curious observati<m of M. Ba'illy's. That physician, <»i
opening, in the presence of twenty pupils, a dead body, over the
whole of which there was an emphysema, which was greyer in
the lower extremities than any where else, remarked, that, whea-
ever a Itmgitudinal incision was made, a gas escaped, which
burned with a blue flame. The puncture of the abdomen yield-
ed a stream of it more than ax. inches high. What was v^ re-
markable, was, that the gases contained in the intestines, so &r
from increasing the flame, extinguished it.
M. Julia Footenelle, for reasons similar to those which in-
dufied him to reject the first hypothesis, is of opinion that the
presence of hydrogen gas cannot be admitted as the cause <^
^xmtaneous combustion. He founds this opnion more particu-
larly upon experiments in which he in vain tried to render very
thin slices of flesh combustible, by keeping them for three days
immersed in pure hydn^n gas, in percarburetted hydrogen
gas, and in oxygen gas.
Lastly, He considers the opinion equaUy untenable, that spc»i-
timeouB combustion of the human body is owing to a ccunbina-
tion of animal matter with the oxygen of the air, whatever mvf
be the altaatjons which this matter may undergo: 1. Because
a suffident len^perature is not developed ; 8. Because, admiuiog
this combuBboD as refd, the readuum would be a charcoal, which
D.n.iized by Google
168 On the Spontaneous Combuttion of'tlie Human Body.
could only be incinerated at a red heat, while, on the contrary,
there is nothing l)ut ashes; 3. Because one of the products (^
spontaneous combustion of the human body is an unctuous sub-
stance, which the combustion of animal substances never yields ;
4. Because it scarcely yields any amnuHiiocal products, while such
are always produced by animal combusttou.
After thus rejecting all the hypotheses hitherto proposed, M.
Julia Fontendle concludes that this phenomenon is the result
of an internal decompo^tion, and is altogether independent of
the influence of external agents. We give his own words :
" We coD^der," says he, " what are called spontaneous com-
bustions of the human body, not as true combustionB, but as
intimate and spontaneous reactions, which depend upon new
products originating from a. degeneration of the muscles, t«i-
dons, viscera, 8(C. These products, on uniting, present the
same phenomena as combustion, without losing any of the in-
fluence of external agents, whether by admitting the effect of
the opposite electridties of fierzelius, or by adducing in ex-
ample the inflammaticm of hydrogen, by its contact with chlo-
rine, arsenic, w pulverized antimony, projected into this latter
gas, 6tc
It may be objected, however, that whatever may be the cause
which induces this combustion, the caloric disengaged ought to
be considerable, and consequently should ignite all the objects
in the neighbourhood. We reply to this, that all combustible
substances do not hy any means disengage an equal quantity of
caloric by combustion. Davy has shewn, that a metalhc
gauze, having 160 holes in the square inch, and made of wire,
one-^xtietli of an inch in diameter, is penetrated at the ordinary
temperature by the flarae of hydrogen gas, while it is imperme-
able to that of alcohol, unless the gauze be very much heated.
According to the same chemist, gauze of this kind, raised to
a red heat, allows the flame of hydrogen gas to pass through it,
without being permeable to percarbu retted hydrogen gas. It
is probable from this, that the products arising from the dege-
neration of the body, may be very combustible, without, how-
ever, disengaging as much caloric as the other combustible
bodies known, and without leaving a residuum as the two latter
gases ; and, in fine, we are of opinicui, that, in some subjects,

and chiefly in women, there exists a particular diathesis, which,
coojcsned with the asthenia occasioned by age, a Ufe of little ac-
tivity, and the abuse of spirituous liquors, may give rise to a
spontaneous combustion. But we are far from considering as
the material cause of this combustion, either alcohol, or hydro-
gen, or a superabundance of fat. If alcohol plays a prominent
part in this combustion, it is by contributing to its production ;
that is to say, it produces, along with the other causes mention-
ed, the degeneration tf which we have spoken, which gives rise
to new products of a highly combustible nature, the reaction of
which determines the combustion of the body.
It is to be regretted that the observations hitherto published
are not more complete. We propose to ourselves to collect all
that may fend to throw light upon a subject so important in
anthropology and medical jurisprudence.

It is wiUi much pleasure Uiat 1 add a fltth species of CatOeya to the lour
already in cultivation. Its nearest affinity certainly is to C. Forbem,
bat the general appearance of the flower more nearly resembles C. la-
biata, and it is almost as handsome. C. Fortaii could not be distinguieh-
ed from this by the essential character nven by Lindley in Bot. Reg.
foL 953., to which, therefore, must be added the acuminate membranous
spathe, closely embracing the peduncle, and much shorter than it. The
habit, as shown in Bot. Keg. is predsely the same as C. inlermei&a. i
C. iniermedia has the 3.1obed lip and the stem of C. Loddigesii and C. For-
beta, the approiim sting penanth of C. forJwij and C. Idbiata, the form
of perianth and sharply jagged lip of C. Forheai, the colours and spathe
of C. labiata, only that the spathe is united at its edges, in which dr-
cnmstanoe there is an agreement with C. LodHgesii, but in this, again,
the spathe la pointed, and much shorter than the peduncle.
We received our specimens, along with many other valuable plants, from
Hr Harris of Bio Janoro, by Captain Graham of his Majesty's Packet
Service, in 1824. They have been kept in the stove In pots of decayed
\bA, and the spedmen now described flowered for the first time in apring
1SS6, but met with an acddent before it could be figured or described
It fur the second time flowered last April, and remained in perfection
several days. Another plant has blossomed while this sheet was at the
press. Other Upechnens, subjected to precisely the same treatment, have
remained without the least alteration in their sppearance since they were
Imported. The suly'ect of the present article is now pushing its roots
iVee^ over the pieces of bark. A figure taken from it will be )j^ven by
Bt Hooker in an early number of the Botanical Magazine. '^

Debcbiption — Shrub erect; stem round, btown; bnmehet erect, green
when young. Leavet linear, and very slender, slightly twiated, mucro-
nate, obscurely channelled on Ijoth sides, veinless, slightly scabroua, im-
bricated, persisting, veiy numerous. fnAincfei axiUsTy, crowded at the
eltremltieg of the bmnches, erect, elongated, slightly scabrous, and
having a few scattered, ovato-acuminate, bluiah bractee, but no flowers
except at the top, wli«^ they support a short spike. Fioatrt in the bud
slightly tinged purple, ailerwards white, epieading, each sessile in the
axS of a bractea, which is larger thaji those below. Caiyi pubescent ;
tube curved outwards, and obscurely tetragonous, limb inflated, bi-la-
blatei upper lip pointed, reflected ; lower Up of three straight erect teeth
of equal length, but the two outer are rather broader than that in the
middle. Stamen* 4, inserted into the throat of the cslyx ; tilaments
short, double, the two portions of that under the acute segment of the
perianth, adhering to each other throughout Iheir whole length, the
other three clefl; ; anthers brown, cordate, that on the first filament hi.
locular, those at the sides unilocular, and adheringtoone-half of the fila-
ment imlj J there is no appearance of anther on either of the pointed ter-
minations of the filament on the lower side of the calyx ; pollen white.
Gormen obversely conical, silky, and crowned with a long tuft of unequal
hwrs ; oouiei few, green, pear-shaped, flattened ; ityle passing out between
the segments of the barren filamentf, reaches beyond the stamens, en-
larging upwards ; ttmna hooked.
Our plant was raised from seed sent by Mr Alton from the Botanic Gar-
den, Kew, in 1823, under the name of C. ereclrtm, and has finwered in
spring for several years. It Is kept in the greenhouse, and remains a
lung while in flower. The leaves are longer, and less crowded than in
Mr Kudge's figure, no doubt from our plant being more vigorous. The
, ^ singular connection of the anthers in the bud, will be detailed by Dr
Hooker In dissections accompanying a figure in the Botanical Magazine.

Debceiptiox — Annual or biennial £^m more or less leafy, branched,
clothed with loose hairs ; branches spreading, having pubescence like
that on the stem. Leavet ovute (the root-leaves sometimes nbovate),
flat, seriated, velnless, but with a strong middle rib pr<uecting be-
hind, hispid with tutled, branched, spreading hairc. Fedunclei slen-
der, many-flowered, oppodte to the leaves, erect, about three inches
long when half the flowers have been expanded, slightly Tiairy as for as
the lowest pedicel, above this smooth and shining, haiis simple or

gular on its surface. Seede numerous.
Seeds of this plant were received trom Dr Richardson in November 1887,
along with an extensive collection made by Mr Brummond and him in
the expedition to the northern coast of America, from which they had
just returned. It was raised under a cold frame in the Royal Botanic

Professor Jameson bj Dr Richardson, after bis first expedition, leavcti

the correctness of the synonjme from De Candolle, which Ur Richardson
quotes with doubt. This I should think distinguished, among other marks,
, by its oral, subacute leaves, and by the petals being nearly elLi[iticaI. ^

The rough leaves and scarcely aneular stems of this plant would have
made me consider it as specifically distinct from Erioslemon talici/olita of
Smith (Crowea sali^na of Sieber. not of Smith], had it not been for its
identity with what Dr Hooker believes to be authentic specimens of
this in bis herbarium. It was raised at the Royal Botanic Giaden, Edin-
burgh, fi'om seed sent from New Holland by Mr Fraser in 1823, under
the generic name otCreuxa, It has tloweied in April last year and this,
has received the ordinary treatment of New Holland plants, and does
- not seem of free growth.'

Nuttall quotes, though with doubt, the P. imtjtora of Michaux as a syno-

dinen even of^ this ever is, and as the inflorescence is quite different,
they certainly are distinct, .though P. paut!^filSa has often one flower on-
ly. The ^)ecies is altoirether overlooked by Michaux. De Candolle,
in his ProdromuB, and Don, in Bortus Canlabn^nsis, 8th edit, quote
M a synonyme for P. pavrijolia, P. purpurea of Hortus Kewends.
Mr Lindley, in the 10th edition of Hort. Cantab, considers these dis-
tinct ; and if there Is no mistake in P. ptirpurea being called a shrub in
Hort. Kew. they must be so, but by others it is described as herbaceous.
This doubt can only be removed by a reference to the specimen, which
probably exists in the Banksian herbarium. Our plant is altwether dif-
ferent &om P. purpurea of Nuttall, which is P. lonjruinea of Michaux
and Pursh.
This beautiful plant flowered spadnely last year in the nursery^garden of
Mr Cunninghame, at Comely Bank near Edinhuigh, having been intro-
duced f^nm Canada by Mr Bltdr. Duiing the month of May 182S it
has flowered abundantly, and formed one of the pleasing objects In Mr
Cunnin^iame's extensive collection. It has spread itself wldelv among
loose vegetable soil, in a cold frame, under the shade of the garden-wall.

1888, Feb. 23. — Robert Jameson, Esq. President, in the
chair.— The Secretary read a notice r^arding a living Ocelot,
or Felis Pardalis, from South America, communicated by James
Wilson, Esq. The animal was a female, nearly of full aze;
had been almost two years at Liverpool, and had lately been
transferred to the menagerie of the Zoological Sodety in Re-
gent's Park.
Dr R. E. Grant then read the second part of his account of
the anatomy of the Perameles nasuta of New South Wales,
treating particularly of the organs of generation.
March 8. — David Faiconek, Esq. V. P. in the chur.—
The Secretary read a notice of the wasting effects of the sea,
which have exposed a submarine forest on the shores of Che-
shire, between the rivers Mersey and Dee, by Robert Stevenson,
£sq. (nvil en^neer.
Mr G. A. W. Amott read two memoirs : 1. On the Mines
of the Higher Pyrenees ; !!. On the Marbles of the Higher Py--
renees. — The Secretary read a cunmunication from the Rev.
John Macvicar, A. M. of St Andrew's, describing a rare fish,
the Forked Hake of Pennant, which had been cast ashore near
St Andrew's in a storm, A drawing of the fish, made by Mr
Macvicar, was exhibited to the meeting.-^-Mr Deuchar, lectu-
rer on chemistry, then read a notice of keeping entire the crys.
tale of efflorescent and also of deliquescent salts, by means of
surrounding them with an atmosphere, formed from an essendal
ml, such as oil of turpentine.
March 22. — David Falconar, Esq. V. P. in the chair. —
The Rev. Dr Scot of Corstorphine read a paper on the great
fish that swallowed up Jonah, and, after three days and nights,'
cast him out on dry land ; shewing that it could not be a whale,
as often supposed, but was probably a Squalus Carchariais, or
white sharii.
At this meeting was also read the first part of a Memoir on
the Lunar Compass, &c, by Mark Watt, Esq, (For an ac-'

Esq, Hill Top, near Wetherby, of the great oak of Cowthorpe,
in Yorkshire, iliuslrated by a drawing.
SCIENTIFIC INTELLIGENCE.
1. On the Comet of 1832, which some predict is to destroy
our Earth. — Some German journals predict the appearance of a
comet in 183S, which must destroy our globe, and this has been
cojned and commented on by the joumtdists of other countries.
In a letter dated May 13. 18S8, addressed to the French
Academy of Sci^ces, the author, M. G***, a professor in Paris,
ventures to put the question to the Academy, whether it does not
consider itself bound in duty to refute as speedily as possible this
ridiculous assertion. ** Popular terrors," he observes, " are pro-
ductive (^serious consequences. Several members of the Academy
may still remember the actudents and disorders which followed a
tamilar threat, imprudently communicated to the Academie des
Sciences, by M. deLalonde, inMaylTTS- Persons of week minds
died of fright, and women miscarried. There were not wanting
people who knew too well the art of turning to thar advantage
the alarm inspired by the approachmg comet, and places in Para-
dise were sold at a very high rate. The announcement of the co-
met of 1832 may produce »milar effects, unless the authority of
the Academy applies a prompt remedy, and this salutary inter-
venliou is at this moment implored by many benevolent persons.
As it is extremely probable that the Academy will make no re-
ply to this letter, we shall here enter into some det^ls which
will shew how destitute of foundation these popular errors are,
which M. G " * • dreads. The comet which is to appear in
183S, is the comet of six years and ibree quarters, of which the
(H-bit waR colcul^ied in France^ by one of our most disdngui^ied
D:it.:f:l.vG00gIC
Scienii/ic IntelRgence. — Astronomy. 181
astroDomerB, M. Damtnaeau, member d the Academie ika
Sciences. All that has been sold id Grennany respecting this
comet, is founded oq the results obttuned at Paris. Now, t^ese
results are so far from being terrifjing, that they do not even
leave the smallest possilrility of an accident. The comet of 18S2,
in its shortest distance from the earth, will remain more than
dxteen millions of leagues from it. It might come a thousand
times nearer before any danger could be apprehended. In
1770, a comet came so near as 750,000 leagues (about nine
times nearer than the moon). Lalande estimates the distance at
which a comet might produce sellable ef^ts on the earth, at
18,000 leagues. Whence, then, comes the error of the journalists,
of whom the author of the letter speaks P Without doubt, solely
from the circumstance, that the comet in question will pass very
near the earth^s orbit (at 4J diameters, from 13000 to 14000
leagues); so that, in fact, were the earth to be at the time in the
part of its orbit nearest the comet, some alarming disturbances
might ensue. It is unnecessary to say that so gross a misappre-
hension as that wbidi we have just pointed out, was not com-
mitted by any astnmom^. The only respectable publication in
Germany on tiie subject is a letter of M. Olden, in which that
astronomer gives an account of the results obtained by M. Da-
mcnseau ; and it is without doubt, because ignorant persons have
seen in this letter that a comet will approach very near the
earth''s orbit in 183S, that they have persuaded themselves of its
collision with the earth. M. 6 * * *'s letter contains an assntion
with reference to Lalande, winch we think it our duty to refute.
That astronomer was but the very innocent cause of the general
toror which pervaded the public mind in 1773. The following
is the real case :— Newton, in q)eaking of the consequences that
might result fnrni a comet's coming in contact with the earth,
had said that Providence had so arranged as to render such a
colhnon imposable. Lalande thought differently. No orbit, it
13 true, was known that might interfere with that of the earth ;
but the orbits might be sensibly altered by the planetary attrac-
tions. Besides, the orbits of all the comets were very far from
being known. Was it not rash to pronounce it certain, that
none of the orbits hitherto not calculated, could come into con-
tact with that of the earth, and that, of those known, none could

ever be disarranged, so as to intersect it ? There was nothing
but what was very Justin these remarks. Time has coofirnwd
them, BiDce the orbit of the comet of six years and three quar-
ters passes so near that of the earth, that the smallest distur-
bance might cause their iutersecticHi. But before a disaster could
happeo, it would not only be necessary that the (»-luts should
tueet, but also that the bodies tbemselTes should liappen to be
at the p<tint of' intersection, and the probabilities of such a coa-
cunence are infinitely small. This was M. Lalapde^s opiaton.
He drew up a memoir on'the subject for a pubUc meeting of the
4cademy ; but, happenii^ to be last in the order of readers, the
time passed away, and it was not read. The title Reflexions ntr
Us cmniles qid peuVint apjnvchea de la teiTe, annoiuiced a sub-
ject calculated to interest the greater nutnber of hearers. It was
asked. What the memoir contuned P and the answer was, that it
contained an account of the effects which a comet stnking the
earth might produce. A noise went abroad that the comet was
to come, and that it was predicted by Lalande. Maupertuis, in
his letterson the same subject, speketin a much mcae positive
and terrifying ilianner, and yet nobody took notice of them ; but
Maupertuis was sot pOntively kn6wn as an astrommier ; he had
not made almanacks ; he had not the power of inserti^ in the
journals accounts of all the astrcmomical phenomena. The alarm
exdted by this alleged prediction was so general, that the heu-
tenant of police wished to see the memoir ; he found nothing in
it to authorise the terrors that had arisen, and orderird its speedy
publication. When it was printed, nobody would believe it.
It was pretMded that the author had suppressed the fatal pre-
diction, not to Xetnfy by the announcement of a catastrophe from
which he bad no means of witbdrawii^ himself. The same ter-
rors were renewed at vuious epochs, but with less vit^ence, and
the blame was always laid upon Lalande, who had not said a
single word on the subject. At the {»%sent day, comets are not
so general an object of terror. In proportion as the mass of the
population becomes more enligbteited, superstitious terrors of all
kinds are less to be dreaded. The conjunctions of the planets,
which were formerly the cause of much more violent, and still
more unreasonable fears ; and evlipses, which so long divided
with comets the right of terrifying the nations of the earth, have

rently from the effects of a lateral explosion ; several doon and
partitions were thrown down, a large mirror in the cabin was
shivered into small Jragments, and a pianoforte was thrown
down, its top blown off, and broken in peces. The loudness of
the exploson was appalting, and spread universal consternation.
A sulphureous smoke, which had issued with a bluish flame
from the batches, filled the cabins, and at first inspired alarm,
lest the cargo in the hold, consisting chiefiy of cotton and tur-
pentine, had taken lire ; but, on clearing the main hatch, it was
soon ascertained that no dang«: from fire existed. The ship,
however, had sprung a leak, which made four inches of water
every hour, but which, on working the pumps, was found to be '
under command, and would not prevent her proceeding on her
voyage to England. When the first terror created by the ac-
cident had somewhat subsided, it was found that none of the
passengers or crew bad sustained any injury. The chief mate
was sleeping in the birth oppodte to the main hatch, near the
spot where the lightning entered the store-room, the lock of
which was forcibly driven into his cabin ; hut he was not him-
self affected by the shock, and a quantity of gunpowder which
was keptainder bis bed, was fortunately notignited by the light-
ning. An ewer and a basin, placed in a stand over a cfaild*s
bed, were thrown down by the explosion, but the child had es-
caped unhurt. A remarkable eflect was, however, produced on
an elderly gentleman, who for the last five years had not been
able to walk lialf a-mile at a time ; terrified by the crash, he
fi>rgot his delnUty, and, springing from his bed, rushed on deck
with Angular quickness and agility. He has retained, ever
mvx the event, the pow^r over the muscles of his limbs, deri-
ved from this sudden motion. The threatening aspect of the
heavens, the appearance of numerous water-spouts on the sur-
face of the sea, and other electrical indications, gave rise to
apprebenatms of further danger, and induced the capt^n to put
up the conductor, with which he was provided, but which had
not been previously applied. It was made of iron links eigh-
teen inches long, connected by iron rings, one inch in diameter ;
and was furnished at the top with an iron rod, four feet long,
and half an inch in diameter, tapering to a fine point This
rpd was fixed so as to rise three feet above the main royal mast-

he«d ; and the chain was made to descend along the back-stay,
and below vas kept at a distance of ten feet from the starboard
bulwarks, by a light vooden outrider, or spar. Its whde
loigth was 145 feet, of which about nine feet of its tower part
descended into the sea- The wisdom of adopting this precau-
tion was soon apparent, &r, in the course of the same morning,
the ship was struck by a second explofion, which is stated by
the unanimous testimony of all on board to have far exceeded .
in violence the first. It melted a great part of the conductcH-,
producing a vivid combustion of many of the links, which
burned Uke so many tapers ; and, descending into the sea, dart-
ed <^ to a considerable distance along the surface of the waves.
The reastance to its passage was so great, aa to cause the ship
to reonl with a sudden and violott shock, so as to throw down
sevraal of the crew. The melted inm of the conductor fell in
large drops on the deck, which, although already strewed with
hailstones that had previously fallen, intermixed with rain, was
set fire to in many places by the ignited metal. No damage,
however, was done to the masts or rigging, nor the least injury
to any of Uie crew, with the exception of a carpenter, who being
at work with an iron auger in his hand, recaved a smart shack
through the wrists, which occa»oned a livid tumour which was
still viaUe dz weeks aAer the accident. Soon after the arrival
of die vessel in Liverpool, she was docked, in order to ascertain
what dum^ she had sustained. Some oS her planks were found
to have started, but her timbers were uninjured. Every instru-
ment made of steel, such as the carpenter's tools, and the knives
and folks, and also those made of soft iron, even to the very
noils in every part of the ship, has been rendered perman^tly
magnetic. All the watches and chronometers were either stop-
ped or rendered useless, by the magnetism imparted to the ba-
lance-wheels and other parts of their works that were made of
steel. Contrary to what usually happens from shocks of arti-
fioal electndty, the lightning had given a strong northern po-
larity to the upper part of the conductor. Many parts of the
iron work, indeed, had acquired magnetism corresponding to
-their position with respect to the magnetic direction ; but in
others, no relation of this kind could be traced. Great changes
were produced on the magnetism of the compass needles, in many
of which were found several sets of poles, and thor indicatims

rests were shivered and stripped of th^ leavei and bnuiches :
^ose <^ gigantic ^ze, which resisted the blast, were torn up by
the roots, and harled to a great distance. Groves were torn
from the mountain precipices ; and vast masEes of earth and
rock precipitated into the valleys with terrific iHMse, choking the
course of the rivers. The fearful sounds in the air and on the
earth ; the peaUng thunder ; the vivid lightning : the howling of
Ihe wind ; the crash of falling trees and rocks, filled every one
-with affright ; and many thought that the end of the world was
at hand. Some fled to caverns for safety, for their frul houses
were blown down, and the air was filled with the trunks and
iiranches of trees, and even with fragments of rocks, carried
akmg by the fury of the tempest. When the hurricane reached
the harbour, it whirled the ships round as they lay at anchor ;
snapped thdr cables, and sank three of them to the bottom, with
all who were oa board. Others were driven about, dashed
against each other, and tossed mere wrecks upon the shore, by
the swelling surges of the sea, which, in some places, rolled for
three or four miles upon the land. The tempest lasted for three
hoars. When it had passed away, and the sun again i^tpeared,
Uie Indians regarded each other in mute astonishment and dis-
' may. Never in th«r memory, uor in the traditions of their an-
cestors, had their island been vi»ted by such a tremendous
storm. They believed that the Deity had sent this fearful ruin
to pum^ the cruelties and crimes of the white men ; and dedar-
ed that this people had moved rfie very air, the water, and the
earth, to disturb their tranquil Hfe, and to desolate th«r isluid.

read a memoir on the relations that may exist between electri-
city and heat. The author conceived, tliat, in order to ascend
to the origin of electrical phenomena produced by heat, it was
nece^ry to seek in the bodies which are bad conductors of elec-
tridty, properties having some analt^ with those which heat
developes in tourmaline. The experiments whit^ he made with
this ol^ect afforded him the fbllowing results :— A small cylin-
der of gkss <M- gum lac, suspended by a mlk thread in the into.

rior of a bell heated to !!d°, is attracsted by a stick of. gum lac,
the moment it begins to cool. The.attxactJ(ni ctHitinues bo long
as the cooling lasts. If the small cylinder has been raised to
S0°, it will acquire, during refrigeration, be«des the property of
attracting, two electrical polesj which disappear when the, tem-
perature rises. At 100'' and 150°, the phenomena are the same.
Thus, under the influence of an electrified body, a small ^ass
cylinder acquires, at the moment of cooling, two electrical poles,
which vanish rapidly when the temperature is raised. These
efiects are analogous to those which tounnsline presents in the
sune circumstances, with this difference, that the development
of electriuty in the latter is produced by circumstances of crys-
tallisation. Whence it may be concluded, that, in the expan-
«on of bodies, there is an absorption of electricity, and probably
an emission during ocmtraction. M. Ampere's ingenious theory
regarding the electrical nature of atoms, accounts in a sadsfac-
Uxj manner for these imp(atant facts. M. Becquerel then gave
an account of the new researches which he has made with re-
spect to tourmalines, from which there results, that tliese mine-
rals, when of a certain length, are not electrified by any of the
means of exrating that power with the as^tance of heat ; that,
in ptoportioa as they diminish in sze, they become more elec-
trical ; and that, admitting this law to continue to the smallest
particles of bodies, these must assume a considerable electrical
intensity on the application of weak variations of temperature.
The facts contuned in this memoir appear to have thrown much
tight upon the electrical state of atoms. M. Becquerel is of opi-
nicm, that they are capable of leading to accurate ideas respect-
ing the cause of the great phenomena of nature. All kinds of
glass are not adapted for the experiment. Those which are
highly alkaline (and almmt all that are made at present ate of
this kind) are too bad ctmductors to allow the phenomena, an-
nounced by M. Becquerel, to be observed. That learned gen-
tleman owed the discovery of the remarkable facts which he
made known to a fortunate chance, which led him to make use
of glasses manufactured fifty years ago. When he used glass
of the present day, all the f^enomena disappeared. He soqd
discovered that this was owing to the great quantity of soda em-
[doyed in the manufacture of glass at present.

19- On the Electritity disengaged by tke cleavage of regu-
larly ctyatallixed bodies ; by M. Bec^uerel.— Many facts shew,
that when adhesion takes place between two bodies, in conse-
quence of a reciprocal attraction between the surfaces, and one
of them is not a good conductor of electricity, they each assume
an excess of oppoate eiectridty at the moment of their separa-
tion. For example, glass, gum-lac, &c. immersed in mercury,
exercise a certain adhesion to it ; and, on being withdrawn, are
found to have acquired an excess of electricity, the species of
which depends upon particular circumstances, which M. Des-
saignes lias carefully desL'ribcd. Gum-lac, melted and poured
upon glass, contracts an adherence to it, as is known ; on being
separated, they each assume an excess of opposite electricity.
It is extremely probable that glass, gum-lac, and other bodies
immersed in water, would come out electrified, did not the mo-
lecules of the liquid stick to their surface, that is to say, did not
the affinity of water for these bodies exceed that of the mole-
cules for each other. In like manner, in the electrical experi-
ments of pressure, there is always obtained a development of
electricity, so inuch the greater the stronger the adhesion be-
tween the compressed bodies. For example, on withdrawing
from pressure two Ints of cork, a slight re^stance is sometimes
experienced ; the disengagement of electricity is then more con-
Nderable than if there had been no adhesion. Similar effects
are especially observed, when cork or elder pith is pressed against
a perfectly polished diamond facet. Some natural philosophers
have attributed them to the friction which the molecules expe-
rience at the moment of separation of the two bodies. This ex.
plsnation does not appear to be correct, for the above cxpcri-
ment evidently proves, that the partial frictions which the mole-

cities undet^ whai the pressure k diminidKdt have no inf
in modifying the disengagement of electricity. Ekstidty is
therefOTe a prindpat cause of the effects. The dectrical phe-
Twmena of pressure and those c^ cleavage haye strong relations
to each odier; for, When plates uf mica or seknite are quickly
separated, each of them bears an excess of opposite electricity.
If they are brought together again, and placed in the position
which they originally occupied, a slight pressure b^ng at the
same time applied, the same electrical ph«)omena are obtained
as when they were separated. We therefore see, that pressure,
which effects a mechanical appro^mation of the molecules,
produces the same effects as the force of aggregation, which only
determines a more immediate contact of the same molecules.
These phenomena do not take place indefinitely ; fc»- the ex-
posure to the air of newly cleft laminie deprives them pretty
rapidly of their electrical prc^nsity, perhaps oo account of
the hygrometric water which they absorb. All regularly crys-
tallized substances possess the same property as miea and sul-
{Aate cS lime. I hare proved it with respect to Iceland qnr,
Burphate of barytes, fluate of lime, topaz, &c It is essMituJ
that the crystal be regularly split, for when it is fractured,
it manifests no dectrical effect. It may, in fact, be easily
conceived, that, if the cleavage is not distinct, there' may be
lamins which assume one electricity, and others a contrary
electricity. It then happens that the sum of all these electrid.
ties may be nothing, which is most commonly the case. Topaz
presaits only one direction of cleavage, perpendicular to the
axis of the crystal, according to which the distribution of the
dectridty takes place, when the t^nperature of this substance
is raised to a certain degree. The most natural supposition
whidi suggests itself is, that the lamioee being in two difflecait
states of e^tricity at the moment of tbeu* separation, may be
conndered as the elements of a pile. Now, this is not the cas^
for it would be necessary that the Iwnioffi similarly situated with
relation to one of the summits c^ the crystal, should always a»>
sume the same electricity by cleav^;e ; which does not hi^

the last volume of the Transactions of the Batavian Society of
Arts and Sciences, is on interesting paper by M. Van Angel-
beck,, on the Island of Liogga. It is divided into three parts.
In the first, he connders the island in a geolc^cal point of view ;
the second he devotes to tbe history and moral condition of the
Malays ; and in the third he describes their government, trade,
and occupations. The island ofLingga ia the actual residence
t^the primitive Malaya. Its capital, called Kwala Dai, is the
ordinary place of abode of the Sultan. Its climate is healthy ;
and there are but few diseases, the principal of which are cuta-
neous. This island is very moimtainous, and is covered with
wood. In its forests grows the fine tree called Chakas panicu-
lata, and the soil indicates the presence of rich tin mines. It is .
also sud that there is some gold. M. V^an Angelbeck observes
that the country is magnificent ; that nature fdiews herself there
in all her force ; but that it is vexatious to see that the natives
benefit only partially ftvim its fetility. They devote tliemselvea
but little to agriculture, which is held in disesteem. Fishing is
almost th^r sole occupation, and the fish are abundant and ex-

published in the Philoeophical Transactions for 181S, the au*'
thor tiered it aa a tnnjectiire, that the metals of the alkalies
and earths might exist in the interior of the globe ; and, on be-
ing reposed to the action tS air and water, give rise to vcdcanic
fires, and to the production of lavas, by the slow cooling of
which, basaltic and other crystalline rocks might subsequently
be formed. Vesuvius, &om local circumstances, presents pecu-
XiBi advantages for investigating the truth of this hypothecs;
and of these the author availed himself during his residence at
Naples, in the months of December 1819) and o! January and
February 18!H). A small eruption had taken place a few days
before he visited that mountain, and a stream of lava was then
flowing, with considerable activity, from an aperture in the
mountain a little bdow the crater, which was throwing up
showers of red hot stones every two or three minutes. On its
issuing &om the mountains it was perfectly fluid, and n^rly
white hot ; its surface appeared to be in violent agitation from
the bursting of numerous bubbles, which emitted clouds of
white smoke. There was no appearance of vivid ignition in the
lava wheirit was raised, and poured out by an iron ladle. A
portion was thrown into a glass bottle, which was then closed
with a ground stopper, and, on examining the air in the bottle
some time afterwards, it was found not to have lost any of its
oxygen. Nitre thrown upon the surface of the lava did not
produce such an increase of igiution, as would have attended the
presence of combustible matter. The gas disengaged from the
lava proved, on examinaticm, to be, common air. When the
white vapours were condensed on a cold tin plate, the deposit
was found to con^t of very pure common salt ; and the va-
pours themselves contained nine per cent, of oxygen, the rest
bedng asote, without any notable jH'oportioB of carbonic acid or
sulphurous acid gases; although the fumes of the latter of these
gases WM« exceedingly pungent in the smoke from the crater of
the volcano. On another occasion, the author examined the sa-
line incrustrations in the rocks near the ancient bocca of Vesu-
vius ; and found them to consist principally of common salt,
with some chloride of iron, — a little sulphate of soda, — and a
still smaller quantity oi sulphate or muriate of potassa, with a
minute portion of oxide of oopper. In one instance, in which
19^ Scientific InteUigence.~—Geoiogy.
the crystals hada purfJish tint, a trace of muriiite of ctdttlt mu
detected. From tlie observatiitms made l>y the author at di&.
rent periods, he coacludes, diat the dense white wnoke which
rote in immense columns from the strcaca of la*a, and which re-
flected the morning and evening light of the purest tints of nd
and orange, waa produced by the »alts which were subJimed
with the steam. It presented a etrikiog cootrait to the Uack
smoke arinng from the crater, which w«s loaded with earthy
particles, and which, in the night, was highly luminous at the
moment of the exploauni. The phenomena observed by the
author afford a sufficient refutation of all the ancient hypoUteses,
in whidi volcanic fires were ascribed to such chemical causes, as
the combustion of mineral ooal, or the action of sulphur upon
iron ; and are perfectly consistent with the auppoution of their
depending upon the oxidation of the metals itf the earths upon
wi extenuve scale, in immense subterranean cavities, to which
water, or atmospheric air, may occasionally have access. The
subterranean thunder heard at great distances under Vesuvius,
prior to an eruptiiHi, indicates the vast extent of these cavities;
and the existence of a subterranean communication between tlie
Solfatara and Vesuvius, is established by the fact that, wtmt-
eva the latter is in an active state, the former is comparatively
tranquil. In confirmation of these views the author remarks,
that almost all volcanoes c^ considerable magnitude in the old
world are in the vicinity of the s^; and, in those where the sea
is more distant, as in the volcanoes of South America, the wa-
ter may be supplied from great subterranean lakes' ; for Hum-
bolt Mates, that some of them throw up quantities of fish. The
authm- acknowledges, however, that the hypothesis of the nu-
cleus of the globe being composed of matter liqu^ed by h«st,
offers a still more simple sqJution of the phenomena of volcanic
fires.
S7' Fossii Hib of a Whale, dueovtrtd in DUwmum near Kemp
Tcwth Brigftton. — -A short time unce, a man employed in c(d-
lecting stones from the beach, near Black-Rock, observed a huge
body projecting fr<Hn the base of the cliff; after satufying him-
self of its nature, by breaking off a large mass of it, he covored
the spot with a heap of sand, and informed the Rev. Mr Wal-
lace of Brixton of the discovwy. Mr W. transmitted xhe in-

fully cleared away, aad the latter completely exposed to view

upon atUmpting to remove it, the whole niasB fell to pieces.
The length of the bone (including the porUon broken off by
the labours) was about twelve feet, bdng upwards of thirty in-
ches in drcamferenoe at the latest extrmtity ; when perfect, it
must have exceeded twenty feet in length. From the structure,
form, and mat %d the bone, there can be no doubt that it was a
portim of a rib of totoe apecies of whale ; and we believe it is
(he only instaoce of the remains of this animal having been
found in the diluvial depoutes of England. The stratum in
which it occmred is stated in Mr Mantell's Geology of Sussex,
to contain the bones and teeth of the elephant, horse, ox, and

or rubbish, which has filled up'a valley in the chalk. Some of
the largest fragments of the bone are removed to Mr ManteFs

siderable time, been satisfied as to the cause to which the forma-
tion of the vitreous tubes occurring in elevated sandy districts
ought to be refnred. The name of lightning tubes that hag been
given them, sufficiently indicates their being regarded as pro

imi\a internally, and rou^ on the outside. Our read^s will
recollect, that very lately a young German naturalist presented
to the Academy some of these tubes, the lengUi of whidi extend-
ed to serenteen feet. Without harbouring any doubt respecting
the mode of formation of. these tubes, it has been asked, how
dectndty could produce effects so intense, and iriiich have been
conndered so different from those obtained from artificial electri-
city. The authors of the experiments, the results of which M.
Beudant communicated to the Academy, formed the idea of at-
tempUng to produce li^tning tubes by artifidal electricity.
They employed, for this purpose, CharWs batttoy, at jHresent
in the CoU^e of France, and actually succeeded in forming
fragments of tubes perfectly resembling the natural Hgfatning
tubes, only that their walls were less sohd, and thar length did
not exceed a few centimeters.
ZOOLOGY.
30. Cuckoo kept alive in confinement for nearly a year past.
—This specimen was taken from the nest of a titlark, near the
village of Currie, in the end of July 18S7. It was then apptu
rently about a fortnight old, and was not fully fledged until six
weeks after. At first it was fed with bread and raw eggs made
up into a paste. AAer this, it was fed with roasted meat cut
Xpto smalt pieces; and ulumately with raw meat, which it pre-
fers, but will not take unless perfectly fresh. At present it eats
about a pound of meat weekly. It is very fond of insects of all
kinds, and in autumn seemed to prefer the larvae of butterflies.
Its first moult commenced in the end of March last. Previous
to this, the colour of the upper parts was deep brown, spotted
with reddish-brown ; the breast and belly greyish-white, with
transverse bars of brown. During winter, it was dull through
the day, and restless at night, flapjnng its wings for hours to-
gether. At present, it is active through the day, and quiet at
night. About the beginning of March it was first heard to ut-
t«r its peculiar cry, which it has repeated many times since; and
one morning in the end of April it continued crying for a whole
hour. Itschirpingcry was given upitbout January. At present'
' The spedmeii was ibewn at a meetiiig of the Wemerian Sodetv IStb
Ajuil 1828: but, unfortuDatel;, at the beKinnlng of this month, June 1838,

it has a sharp weak BCTeam, which it utters on beog fnghtcned
or irritated. It did not eat of itself uotil nearly three months
after it was ftnind. It has always be«i veiy fond of heat, and
is extremely sensible to caid, shivering intensely when the tem-
perature is low. When the sun shines upcHi it, it expands all
ite feathers, eq)eciaUy those of the tail and wings, turning its
back to the heat. When eating, it holds the piece of meat
about three or four seconds, squeeang it with the points of its
mandibles, which is supposed to he an instinctive action, the ob-
ject c^ which is to deprive its prey of life, previous to swallow-
ing it.-— The late Mr Terapleton of Belfast succeeded in keep-
ing a cuckoo over mnter, but it died in March, whoi the first
moult commenced.
31. Respiration of the Crvalaeea, — MM. Audouin and
Milne Edwards, read lately to the French Academy of Sciences
a fourth memoir " on the Anatomy and Fhysiolc^ of the Crus-
tacea.^ The following is the title of thear new memoir : De ia
Respiration afrienne dea Crustacisy et dea modificationa que
FappareU branchial Sprouve dans lea crabea terrestres. There
result irom the observations and experiments ctmtained in this
memoir, 1. That, in all the Crustacea, the branchite are fitted to
perform the functions of respiratory oi^ans, in the air as well as
in water ; S. That the more or less rapid death of the aquatic
species exposed to the air depends uprai vuious causes, of which
one of the most direct is the evaporation from the branchic,
which produces their desiccation ; 3. That, consequently, one of
the conditions necessary for the support of life in animals, which
have branchiae, and live ia the air, is the having these organs de>
fended against desiccation ; and, lastly, That these indispensable
dispoeitioDs are actually met with in the touriouroux and other
land crabs, which all possess various organs destined faMabsorb-
ing and ke^ng in reserve the quantity of water necessary for
maintuning a suitable decree of moisture in the branchise.
SX. STtake-catchers. — The secret of rendering docile, and

snake-catchers here rub their hands, previously to taking bold
of the snake, with an antidote compoeed of pounded herbs. The

M. Origin^ Country qfthe Car^u. — ^That many of the pic-
tures given us of this extraordinary race of peof^ have been
ooktitred by the fears of the Indians, and the prejudices of the
Spaniards, is highly probable. They were amstantly the temr
of the former, and the brave and obstinate opponents of the iat^
ter. The evidences adduced ti th^r cannibal prt^iensitifis, must
be considered widi laige allowances iat the careless and inaccu-
rate observations of seafaring men, and the [Heconc^ved belief
of the fact, whicii existed in the aiiida c^ the ^wiiarda. It waa
• custom «nong the natives of many of the idands, and of tAhev
puts of the New World, to preserve the remains of th^ de>
ceased relatives and friends ; s(»netimes the entire body ; soto^
times only the head, or some cX the limbs, dried at the fire;
sometinieB the mere bones. These, wh^ found in the dwellings
of the natives of Hi^xmu^ against whom no prejudice of the
kuid existed, were correctly regarded as rdics of the deceased,
preserved tlirough ^fection or reverence ; but any remains oS
the kind found among the Caribs, were looked upon with hwrw
as proofs of cannibalism. The warlike and unyielding charac-
ter of these people, so different from that of the pusillanimous
nations around tboi, and the wide scope of thar enterprises and
wandnings, like those of the Nomade tribes of the Old Wtnrld,
entitle ^m to distinguished attrition. They wore trwned to

knew how to divide time by day and night, by Uie eun and

yet capable of being verified, to a great d^ee, by geographical
facta, and open one of the lich v^a of curious intjuirj and ape-
culation which abound in the New World. They are stud to
have migrated from the remote valleys embosomed in the Apa-
lachian Mountains. The earliest accounts we have of them, le-
present them with thdr weapons in theu* hands, continually ea-
gaged in w«^, winning their way, and shiftbg their abode,
until, in the course of time, they found themselves at the extrC'
mity of Flmida. Here, abandoning the northern continent,
they passed over to the Lucayos, and from thence gradually, in
the process of years, from island to island of that vast and vet>
dant chain, which links, as it were, the end of Fkirida to the
coast of Faria, on the southern continent The Archipelago,
extending from Porto Bioo to Tobago, was tbor stronghi^d,
and the Island of Guadalot^pe, in a manner, thdr dtadel.
Hence they, made tbdr expeditions, and spread the terrcr of

them landed uptm the southem continent, and overnui some
parts of Terra Firma. Traces t^ them have been discovered
far in Uie interior of the country throu^ which flovs the OroO'

Uumtefca, which empties into the Surinam, dong the Ssqtabi,

that they have extended their wanderings to the diores of the
Southern Ocean, where, among the s^Mrigin^ of Bradlj

85. Temperature tf Plffittta. — Schutzer and Haider have pub-
lished, at Tfllnngen, an account of some experiments on this
subject. They inserted thermomet^^ into the stems of trees,
and so deep that the bulb reached the centre of the tree. The
same was done into a dead stem. It results from these experi-
ments, that vegetables appear to retain a certain medium tem-
perature, which cannot however be considered as originating
from heat evolved by the functions of the plant, as the dead
stem affi>rded the same temperature as the living, but can be sa-
tiabctorily explained by a reference to the bad conducting
powo- of the vegetable fibre and the wood, by which the tem-
perature of the surrounding aerial strata penetrates but slowly
into the interior of the plant.

36. On preiervmg Wine in DraugJa. By M. Imery. —
M. Imery of Toulouse has given us the following simple means
vi pr^erving wine in draught for a con^derahle time ; it is suf-
ficimt to pour into the cask a AaA of fine olive ml. The wine
may thus continue in draught for more than a-year. It is by a
smilar process, that they preserve wine in Tuecany, which they
are accustomed to keep in large bottles, the glass of which is too
tlun to resist the «fiect of corking them tight. The oil, spread
in a tlun layer upon the sur&ce of the wine, hinders the eva-
pwirtim oS its ahxJidic part, as well as prevents it from ccHnlun-
iug with the atmosfdieric air, wbicb would not only turn the wine

tract the tiiroat of his chimney in the following judidous man-
ner. He caused the entire opening at the bottom or throat of
the chimney to be closed up, with the exception of on upright
flue, just above the top of the grate, about a foot wide and hi^,
and which led into the chimney. To the face of this flue he
applied a. square flat frame of wrought iron, having upi^t
grooves made on each side of it, in which a sort of hood, made
of sheet4r(m, could slide up and down. Thia hood is open be>
hind ; it projects about a foot square in front of the diimney
back, over the flre-place or grate ; it is alibied off at its top, to-
wards tbe back of the chimney, and It has a handle in front of
it to raise and lower it by. When the hood is elevated, it serves
to guide tbe smc^e and heated air into the upright op^iuig
leading into the chimney, its sides being closed to fit the up-
right back of the fire-f^ace ; and the fire then burns in the usu-
al manner, but the chimney never smokes. When, however,
be wishes to excite the fire at any time, he lowers the hood un-
til its bottom nearly reaches down to the tops of the cheeks, or
two keepers of the grate, and the fire, by the drai^t thus
caused, instantly revives. In addition to this hood, he likewise
occasitmally hangs upon ledges, formed upon each side of it, an
appendage made of sheet-iron, which lengthens it so that its
sides fit close upon the tops of the keepers, and thus the air can
only giun access to the fire through the front and bottom bars of
the grate, and then, indeed, the fire burns most vehemently. —

much greater merit, of not allowiug himself to be overcome by
Uiose of prosperity. Neither could his birth, which opened to
him an easy path to houours, nor great riches, which came sud-
deoly to lure him to pleasures of all kinds, turn him aside from

him ; the disinterested love of truth was bis only prindple of
action. But if he made a sacrifice of ail that men in general

him seems to have something of the sublime and marvellous'

the Whflle t^ his We^ shewed that this preference was the result
ef a natural taste ; but it was neoesnry for him that it should
be confirmed at an early age by ^nestic examples. Lord

observsUona in natural philosophy. It is probable that he
directed the eivly studies of his son ; although we hare ilo infor-
mation respecting the mecliod winch he followed in educating
him, nor even of the first attempt of the young Henry in the
career of science. He appeared suddenly in it, bat in such a
maffli«', as to shew that it was already fimitisr to him. The

' bodies which furnished them, allhough do one was able to pmnt
out, with pret^iMi, in what these alleged emanatioos consisted.
Mr Cavendish presented his Memoir; and, iil^a few pages,
cleared up the subject. He compared, with each other, the
elastic fluids extracted from lime and alkalieH, that produced by
fermentation and putrefaction, and that which occupies the bot-
toms of wells, caves, and mines ; and shewed that they have all
the same prq>enies, and form but one and the same fluid, to
which the name fA fixed air was from that time restricted. He
determined the spedfic wdght of this air, and found it always
the same, and greater by a third, than that of common air ;
which accounts fcM* the low ponti<Hi it occupies, and the delete-
rious effects to which it gives rise in the bottom of cavities. He
discoTsred that tbis kind fA m possesses the property of com-
bining with water, and then disserving limestone and iron ;
which explains the eflects of incrusting waters, the formation of
stalactites, and the presence of iron in mineral springs. Lastly^
be asserted, that it is precisely the same air that is developed
in the combustion of charcoal, and which rendn^ that substance
so dangerous as an article of fuel.
His experiments <mi inflammable air were still newer and more
striking. This fluid, which was only known by the explo^ons
scnnettmes produced by it in mines, bad scarcely begun to
occupy the attention of philosophers at the time when he under*
took its investigation. Treating it in the same manner as the
former, he shewed that it is identical, ^d possesses the same
jffoperlies, whether it be obtained from the solution of iron, or
from that of zinc, or of copper ; and of these properties, be
more especially pcnnted out its. specific lightness, which is about
ten times greater than that of commcm air ; and <^ which our
fellow member, M. Charles, afterwards made such a happy ap-
plication for rendering the navigation of the air by balloons
sure and easy. It may, in fact, be said, that without Uie dis-
covery of Mr Cavendish, and M. Charles's appUcation of it, that
of Mr:Montg(^er would scarcely have been practicable, so
nany dangers and inconveniences did the fire, necessary for
keeping the air in his balloons expanded, occasion to the
aeronaut.
But Mr Cavendish's investigation i^as followed by otlier Te»

suits, and the importaDce of his discoveries was soon evipced by
their fecundity. The fact once ascertained, that there might
exist various elastic fluids, ctmstant in th«r properties and spe-
dfically different in their nature, first gave rise to Priestley's r&;
searches, vhlch led to the discovery of two new kinds .<^ those
fluids, the phlogisticated and nitrous airs. It was then begun
to be seen how far the different kinds of tur might exercise
their influence upon the phenomena c^ nature, and how little
solidity systems of phyucs and <A chemistry could have, which
were formed without any regard to agents so powerful and uni-
versal. The intellectual faculties agitated by that impatience
of doubt whk^ forms their chief spring, entered into a. sort t&
fermentation, and each endeavoured to supply what he saw to be
wanting in these theories. Bergman^s introducti<n of fixed mr
among the acids, while it amplified chembtry a UtUe, ftxmed
but a slight palliative to the radical defect which had been per-
ceived in it. This stale of things had existed for seven years, when
Lavoi^et was struck as with the first dawn of his famous theory.
Finding a great quantity of fixed air evolved during tbe.reduc-
tion of the metals by charcoal, he concluded that the calcina-
tion of these substances was nothing but their combination with
fixed air. A year after, Bayen reduced calxes of mercury with*
out charcoal in close vessels, and sapped the chief foundation oi
the phlogistic theory. Lavoisier theu examined the lur pro-
duced by these reductions without charcoal, and found it re-
(pirable; and, shout the same lime, Priestley discovered that it
was precisely the part of the atmosphere necessary at once for
respiration and combustion. It was then that Lavoisier made a
second step. Respiration, the cakunation of metals wd combus-
tion, said he, are similar operations, combinations of respirable
lur ; fixed air is the peculiar produce of the ' combustion of
charcoal.
But the phenomena of solutions, the infiammable ^r which
manifests itself in them, were not yet explained. Other six
years were required for the acoompli^ment of this, and it was
Mr Cavendish for whom the honour was reserved.
Scheele had observed that, in burning ioflammable air, neither
fixed nor phlogisticated air was obtained ; all seemed to disap-
pear. Macquer, while trying to arrest the vapour ariang from

tfais eoBibustion, remarked, with gurpiise, seffie moisture on
the Tcsidd which be employed ; but he vent no further. Mr
CKTeodish, who in some measure introduced inflamBtable air
into chemical expaimeiUs, was also the first who aQtwunced the
great iaflueDce vhidi it exerted over the comUiMtim (^ bodiee *.
Cajiying, OB in his first iD¥e^JgiUion, the prerasfw for which
be was distinguished, to a subject hitherto but superfioally exa-
mined, he burnt inflammable mr in dose vessels by the elecljic
spark, su[^lying it by degrees with the inflammable air neces-
sHfy for its combustion. He (aw that the former of these airs
absOTbed a determinate portion of the other, and that the wh^
resolved itself into a quantity at water equal to the wdght of
the gases that had disappeared. This great pbenoiowon, which
Mr Cavendi^ Uxk three years to establish, was announced to
tbeBoyal Societyon the 14th Jaiu]aryl784 Our fellow mem-
ber, Count Monge, who had fonned the same idea, and made
the same expaiments as Mr Cavmdish, communicated their
result about the same time to Lavoiraer and M. de Idi Place.
If the combination of these airs yields water, ,8vd M. de la
Place, it is because they reaidt from its decomposition. At- ,
tenets were therefore made to decompose water in the stune man' I
ner as it had been composed, and they were suceessftil. These I
experimmts became the key-stone to the arch of his new theory,
and explained almost every thing that had previously puzzled
him. In fact, water being but a combination of the two airs,
wherever it exists, it can furnish th«n on being decomposed ;
raid wherever they are framed, it may anse in>m tbdr union.
The solutione of metals were at first deduced from inflam-
ro^e air; and, by a numerous suite of othfif consequences, the
deoompp^tion of organized beings, and the most complicated
tranETormaticm of their principles. In a woffd, the theory of
chemistry was henceforth seated on its basis. Thus it may be
said that this new theory, which produced so great a Devolution
in science, owed its origin to a discovery made fay Mr Cavep-
dish, and that it was a second discovery of the same f^loso-
pher which gave it its final completion. He made a third dtS'
covery, whicli would sufllce to immortalize him, bad the others

jtev9t existed : it w«s that of the compodtion of nitrouB acid, a
a^batance of great utility in the arts, and vary extennvely £f-
ftieed in natiue, re^ectii^ whidi, hefiwe Mr Cavendish's time,
dieiDista had only vague and hypothetical ideas*. Ever since
hia first ezpmin«[ita at the combustion of inflammahle air, he
bad pacared that nitrous acid was fbmed, and that it was
th« more abundant in proportion to the quantity of wbat vas
then called dephlogisticated air, and afterwanla named azote.
UpcHi examining the product of the detonation of nitre by
ch«coal, be,fouad it conpoeed of this same phlogisticated or, .
jutd fixed air. Now it was the diartxial that yielded the latter ;
dw former, therefore, eould be furnished only by the acid of the
nitre. Mr Cavendish quickly proved, by direct experiments,
the accuracy of his cecgerture. By bunuog a mixture of re-
(qiirabk air and phlogiBticated air, by meass of the dcctric spark,
he converted it into nitrous air, which was itself changed into
acid by a new adiStion of respirable mr. Thus the c^menu of
nitrous acid were found to be the same as dioee of the atmos-
phere, hat in diffixent proportioDs ; and frtmi henceforth clear
ideas were cAttained of the universa], and hitherto incomprehen*
attle, generatiDn of that add.
The history o£ this ef)och, the most hriUiaDt that chemistry
ever had, caonot be read witiMmt exciting a sc^t of enthunasm.
SisGOTeiies seemed to prees upon each other. Mr Cavendish,
having communicated that whidi he had just made respecting
lutric add to our fellow-member M. Berthcllet, received from
him in return, that of the decixnposition of amraooia into in-
flammable. air and phlogisticated air. What men and what
timee must those have been !
Mr Cavendish at length undertook the examination of the
»tmo^]liere itself. It produced such vaned effects upon tiving
bangs, that it was natural to si:q>po8e that it must be highty
variable in the proportion c^ its ekmeoits. Priestley, who dis-
cavered pure or res{Hrabie mr, hod also ascertmned the means
cf estimating ' the lespiralnlity of any ^ven air ; all that iras
for this purpoae necessary, was to measure the proportion et it
whidi waa absorbed, when it was nuxed with nitrous air ; but
Ins iDSIruments were still imperfect, notwithstan^g the oor-

recdoDB made upon them by Fontana. Mr Cavendiah, by a
ri^t difTerence in the manual process, gare them a very supe-
,twt \treaaoB *, and, having employed them for txitnparing air
taken in different places and at different times, arrived at the
unexpected result, that the portion of lespirable air is the same
everywhere, and that the smells which bo perceptibly afect
our senses, and the miasmata which so cruelly attack our
healU), cannot be investigated by any chemical means — a result
wbid), although at first ^ght almost discouraging, presents an
immense perq>ective to the reflecting mind, and already shews
in the distance sdences which have not yet been called into
exist^ice, and for which alone is perhaps reserved the secret
of those nhich we possess. M. de Humboldt has confirmed this
fact, in the most distant regions, by means of the inflammable
tar eudiometer, M^f. Biot and Gay-Lussac found it not less
true in the highest parts of the atmosphere which man has been
able to attdn by means of the balloon, than in its lowest strata.
Thus it was -still an agent discovered by Mr Cavendish, that
these adventurous philosophers employed to verify another o(
bis discoveries.
Such are the labours that have asngned to Mr Cavendish
■o distinguished a place among the cultivators <tf chemistry ;
they occupy but a few pages of print, yet they will survive many
lai^ books ( but we must not estimate, the difficulties which
attended them by the space which they fill. To have untied
the secret knot that bound together so many comj^icated phe-
nomena, to have pursued die same principle through so many
windings and metamorphoses, and especially to have explain-
ed with such precision what had for ages eluded the most
expnt [^ilosophers was, in a few minutes, rendered evident to
every c«e,' could be nothing but the effect of meditations, not
only the best directed, but tJie moat obstinately persevering.
Mr Cavendish was a living pnxtf of the truth of the adage of
one of hie most illustrious cotemporaries, that genius is but a
greato- aptitude for patience ; a maxim strictly true, if we add
to it, that it must be the patience of a man c^ intdlect
Another not less valuable quality which be possessed was his
severity in the matter of demonstration. Nothing doubtful was

lutoitted by him, nor could any sopbism pass unperceivedl
HiB character, in this respect, was such, that his friends hasten-
ed to lay their researches before him, assured that if he ap.
^proved of them, no one could find occa^ou to contradict them.
He treated himself more severely than any other; and thus he
was etiaU^ to pve his works such a degree of perfection, that
even now nothing can be added to them, nor can any alteratitm
be made in them, although xhe first of them appeared more than
forty years ago, and although the science to which they refw
has in that interval undergone a complete revolution. They
are, perha[», the only sdentific productions in existence that can
boast of such a merit. This severity, introduced by Mr Caven-
dish into chemical inquiries, was as beneficial to the sdence as
his discoveries themselves ; for it is to his method that we are,
in a great measure, indebted for the discoveries which were
made by others. Until about the middle of the eigbteenth cen-'
tury, chemisiry seemed to have become an asylum for the gra-
tuitous suppositions and baseless theories which Newton had
expelled ih>m phyucs. Cavendish and Bergman pursued them
thither ; they cleared that Augean stable, still overspread with
the rublush of the hermetical {^lilosophy. Since th«r time no
one has dared to operate but on determinate quantities, and by
keepng a strict account of all the kinds of [nxiductii ; and it is
this which forms the disdnctive character of the modem chemi-
stry, much more than its theories, which, beautiful as they
iqjpear to us, will not perhaps be unimpeachable, should the
substances, which have hitherto boffied our research, be aoe
day mastered. Mr Cavendish owed this steictness to a. profound
study of geometry, of which be has also made direct applic&'
tiona, sometimes as happy as his chemical researches. Such,
in parliculsr, is his determination <^ the mean datsity, ch*,
which comes to the same thing, of the total weight- of the

but which, nevertheless, reduces itself to a simple law of me-

this olgect, «iid had coDstnictod, for the {turpoM^ an aj^iata t m
which was uetaij Ihe earns u that alread; eaiplcjed by our
deceased fellow member M. Coulixab, for measurtqg the power
of ekcaiatjf and that of the magnet. A lever, ux feet lon^
bearing at each extremity b small lead ball, was suqwoded bori-
»«talljr, by the middle, to a vertical thread This lever oDce
at rest, a large mam of lead of a givra diameter and wei^it, waa
brought near each of its extreimtiet in a Weral direction. The
attracdoD, exerted by the masses upon the balls, put the lever
in motion. The thread became twisted in acoommqdating itself
to this action, and tending to return to, its first state, made tbe
lever describe small horizontal arcs, that is to aay, the attrac-
fioD of the earth made it describe arcs perpendicular to the pen-
dulum ; and, by comparing the extent and duration of these
oscillations and those of the pendulum, tbe rdaticHi of their
causes was obtained, or, in other words, the relaticm of the attrac-
tive power of the masses of lead, and of that c^ tbe terrestrial
globe. But this presmted only a rude idea of the apparatus, and
of the precautitms and calcuiatjoos which the experimoit required.
The mobility of the lever was such, that the slightest di&rence
<)f beat between the two balls, or only between the di&rent
parts of the air, ocoafflooed a current strong enou^ to m^e it
vibr^e. It was even necessary to estitnate the attraction td tJbe
walls of the wooden case in which it was contained ; and the at
tention required in measuring the extent of its vibratti»% and
even in observing it without altering them by approat^ii^ too
near, was almost infinite. All these difficulties becimie ^pa-
rent only at the moment of pnfomuDg tbe expaiment ; and
the ddicate means which procured tbeir removal, and t^ which
die necesnty had not even bem foreseen by Mitchell, beko^
entirely to Mr Cavendi^ The result waa singular ; the mean
deurity of the gk^ was found to be Cj^d times, or scanediing
less than 5^ times that of water. According to this result, it
would be necesaaiy not only that the ^obe dmuld have no
vacuities in it, but also that tbe materials of its intnior should
be heavier than those of the surface ; for the substances, at whidi
the Qomnon rocks are composed, are only about three, or rarely
lour, times the weight of water, and no known stone has a ^>ecific
gravity so high as five. It might therefijre be imagined that tbe

cKperiment (Viniislwd quite new vivwi i^h mspeci to the thearj
of the eufth. It appeared, at fint, to dijngrae with tboMr ma^
by Maikelyoe in Scotland, in whidi the deviation, produced
by the vicinity of a mountain in the plumb-line of bit inatnif
ments, made him infer a mean density of mly four and a half
times that of Water ; but it is anerted, that, after a more accu-
rate calculation of Haskelyne's expenments, their result was
found to come very near that obtained by Mr Cavendidi.
He was also «te of the first who applied calculation to the
theory of dectiicity. His inii«stig«6oa was pafcnoed before
Mpna9\ woric on the same subject appeared, but {t was nitf
communicated to the pubUc until after. He set out upon the
same hypothecs, namely, that there is but one kind of dlectrical
matt^j Ae molecules of which mutually repel taA other, and
are attracted by other bodies ; but Mr Cavoidisb shews, that,
«uppo«ng this action to be exercised in a proporticMi lesa than
the inverse of ^e cube of the distance, it may be proredj
by means of Newton's theory respeeting the attractioa of a
qohere, that all the electrical matter of a body of that form
ought to come toits surface *. It ia well known that our fellow
member the late M. Coulomb, afiarwards demonstrated, by di.
rect experiments, that the action of dectricity is exercised in
the reverse ratio of the square f^ the distance, and that he proved,
io a much more general manna:, the neceadty of this distribu-
tion at the surface of bodies, whatever their figure may be.
When Walsh announced the analogy betwe^ the shock wlu^
the torpedo gives, and that of the Leydm Tphui\., it was ol^ected
that the fidi in question does not produce sparks. Mr Cavm.
dish immediately endeavoured to explain the reason of this dif-
fiH-encef. He even constructed, after the prineiple of bis expla-
sa^oD, a. sort of ta^fioal ttspcdo, whicb presented tbe same pbo-
nomena when it was electrified. Tbe true cause of animal elco<
tiicity, however, escaped him ; and it was for M. VcAta that it
was reserved to discover as apparatus calculated to mgender
this wonderful fluid without intermismon, and to deotrify itself
tacessantly, — an apparatus very probably analogous, in its ea~
sence, to those with which nature has supplied the electrical
fisbea.

It IB also known that the same Widsh saw sparks in the elec-
tric eel of South America, a fish which posseBses that property
in a much higher d^;ree than our European torpedoes, and
whidi, according to M. Humboldt, is capable of stunning horses
by its shocks.
We have also observations by Mr Cavendish on the height at
luminous meteors *, which mi^t have led to the suppotdtion,
now so well verified, of the falling of stones from the atmosphere.
He wrote a very learned memoir on the means of improving
ineteorologtca] instruments "f-, and made ingenious remaHcs on
the effects of frigorific mixtures, and their limits^. He even
occupied himself with the calendar of the Hindoos, and endea-
youred to compare their confused cycles with our mode of reckon-
ing time {. But the limits of a public discourse do not permit
us to enter into an analysis of all his writings ; we only m«ition
them, to add the examfde of Mr Cavendish to so many others,
which prove that great discoveries are reserved for men habitual-
ly given to contemplation.
, Toward the end of his life, he busied himself with regulating
more accurately the division of the great astronomical instru-
ments ; and it was assuredly carrying to the extreme the love of
accuracy, to be dissatisfied with the art which, of all others, has
carried that quality to the highest pitch.
After this long enumeration of Mr Cavendish's labours, it
will readily be cotnpi^hended that a life so productive could not
have been an agitated one ; but what would not so readily occur,
was the extreme uniformity of his life, and the scrupulous exact-
ness with which he fulfilled the view which had induced him to
devote it to study. The most austere anchorites were not more
faithful to theirs. Among the numerous problems which he
Bolred, he placed in the first rank that of not losing a nunute or
a word ; and he found. In fact, so conTplete a solution of it, that
it will astonish those who are most economical of time and words.
His people knew from his signs whatever be wanted ; and, as he
scarcely ever asked any thing from them, this sort of dictionary
was hut brief. He had onlyone dress at a time, which was renewed

as the former. Lastly, it has even been swd, that, when he went
to ride, fae had to find his boots always ready in the same place,
and the whip placed ip one of them j and always in the same one.
The occa«on <^ assisting at some new experiment, or of con-
versing with scnne one who might afford him instruction, or had
need of his advice, was the only thing capable of interrupting
the established order, or rather this sort of intemipticHi itsdf
formed part of his order : then he indulged himself in the {Mea-
sure of talking ; and his conversation, which was entirely Socra-
tic, did not end until all was cleared up.
In every thing else, his mode of life had all the regularity and
predion of his experiments. It could not even be altered by-an
. incident which, of a certainty, would have produced a great
change in that of any other. Bdng a younger member of a
younger branch, he was rather poor in his youth, and his pa-
rents, it is said, treated him as a man who, to all appearance,
would never become rich. Chance or his real merit decided
otherwise.
One of his uncles who had served in die army in India, umI
who had made a great fortune there, conceived a strong attach-
m«it for him, and left him the whole. Being now the poe-
sesBor of many thousands of pounds, Mr Cavendish had toi
use a few additional signs, to shew what was to be done with
the excess of his income ; but to obtain them, it was still
necessary for him to be repeatedly ui|^ by his banker. It
is said that the banker came one day to tell Mr CavendiA
that he had allowed L. 75,000 Sterling to accumulate in his
hands, and that be was ashamed to keep so large a sum lon^r,
without being r^ularly settled, — a circumstance which assured-
ly proves as much delicacy on the one nde, as carelessness on
the'other. It is said, however, that he ultimately left about
L. 1,250,000 Sterling. Few philost^ers have been so rich,
and few rich peo[de have become so like him, without caring
about riches. This cause of the greatness of his fortune is also
its excuse ;. for we must allow that one almost needs to be «x-
cused when he has acquired so much ; yet he did not omit seek-
ing opportunities of diminishing it : he supported and carried
forward several young persons who gave promise of talent; he

The regularity of Mr Carendish'a life procured him long days
exempt from infirmity. To the i^ of seTeoty-nine he retained
the activity of his body and the powers of his mind. He owed
probaUy to his raaerved nanoers, and the modest tone of his
most impartant wribo^, another not less great advaDtage, and
one which men of geniu* seldom enjt^, that of nevo' having his
repose dialarbed by the jeaknisy of rivals, or the aenmony of
critica. Like Newton, his great couotryotan, whom he reeem-^
Ued in other rei^tecle, he died full of years and of renown, dw-
rished by his coiemporaries, respected by the generatioB which
he had instructed, celebrated aaioDg all the learned of Europe,
preaenting at once to tbe world the aocomfdiahed model of what
aU men of acienoe ought to be, and an affecting example of the

Organic natore ^ves to each region of the earth the peculiar
frfiysiognomy by which it is distinguished. The case is difierent
with inorganic nature in tfte places where the solid enrdope of
the earth is deprived of v^tation. The same species of ro^s,
attracting and repdlii^ each other by groups, disclose them-
selves in the two hemispheres, from die equator to the poles.
In a distant isle, surrounded by onknoivn plants, in a clime
where the stars to which his eye is hi^tuated no longer shine,
the voyager often recognises widi joy the granite of his native
country, and the rocks whidi he has been accustomed to see.
This independence upon the present conttitation of climates,
winch is peculiar to inorganic nature, ijoes not diminish the be-
nefiml influence whicii numerous observadons, made in distanf
countries, have upon the progress of geognosy ; it only ^es

the remains of extinct races ; sometimes of members of yet uft.

is evidently pictured in every mouHain chmn of any extent.
To become perfectly acquainted, however, with the most, im-
pcMliant phenomena of the composition, relative age, and origin
of the formations, it b necessary to compare, with each o^r,
observations made in countries the most widely separated, [»t>-
blems which have long seemed enigmatical to geologists Uving in

yet enable us to understand the uniform bws of nature, by
which the vaiious strata support each other, penetrate into each
other''s substance in the f<^m of veins, or raise each other in
obedience to elastic powers. >
If it be true that our geo^ostical knowledge derives the
greatest advantage from researches made over vast expanses of
. country, it ought not to excite surprise that the class of pheno-
mena which forms the principal object of this memoir should,
till lately, have been examined in a very imperfect manner, be-
cause the points of comparison ore very difficult, and may even
be said lahcnious, to Gad. Until the end of ihe eighteenth
century, all that was known of the form of volcanoes, and of the
action of their suhtfirronean powers, was derived from two moun-
tains in the south of Italy, Vesuvius . and Etna. The former
being the most acces»ble, and, like all volcanoes of inferior el^
vatiiMi, having more frequent eruptions, a small hill became, in
some measure, the type according to which a whole distant
worid was represented, containing the great volcanoes of Mexi-
co, South America, and the A«atic Isles. This nude of rea-
soning might naturally bring to our recollection Virgil's sh^
herd, who, in bis humble cabin, imagined he saw the image of

have risen from the bottom of the sea, and f<Hiued islands, like
that among the Azores, which, in the space of three centuries,
bas shewn itself at nearly equal intervals. Between Epidaunis
and Trez^e, near Methone, in the Peleponneaus, there occurs
a Monte Nuovo, which was described by Strabo, and has been-
seen agmn by Dodwell. It is higher than the Monte Nuovo of
the Fhlegrean Fidds, near B^se, perhaps even higher than tbe
Dew Volcano of JoruUo, in the Pluns of Mexieo, which I found,
surrounded with many thousands of small basaltic oones, that
had issued from the ground, and were still , smoking. In the
basin of the Mediterranean, not only does the volcanic fire es-:
cape from permanent craters of isolated mountuns, which have
~ a constant communication with the interi(H- o£ the earth, a»
Stromboli, Vesuvius, and Etna ; but at Ischia, on Mount Epo-
m^ ; and, according to the accounts <^ the ancients, in the Plains
of Lclantis, near Chalds, lavas have flowed from fissures which
have suddenly opened at the surface of tbe ground.
Independently of these phenomena which belong to historical,
times, to the liaiited domain of sure tradition, the shores of the
Mediterranean contain numerous remains of more ancient effects
(rf the action of fire. Tbe south of Fraqce, in Auvergne, dis-
^ys a particular and entire system <^ volcanoes, arranged in
saies, of trachytic domes, altemaUng with cones p^forsted withL
craters, from which torrenu of lava have flowed in narrow
stripes. The Fhun of Lcmibardy, which, smooth as tbe surface
of the waters, forms the most remote gulf of the AdriaUe Sea,-,
surrounds the trachyte of the Euganean Hills, in which there

Common language, which often gives connstency and dura-
tion to ideas ariong from the most erroneous views of things,
but which also frequently indicates the truth instinctivelyr
pves the name of Volcanic to all the eruptions of subterranean
fires and melted substances ; to the columns of snwke and va-
pour which issue from the heart of rocks, as at Colares, after the
great earthquake at Lisbon ; to the salses or cones of clay which
vomit mud, as{^altes, and hydrogen, as at Girgenti, in Sicily^
and at Turbaco, in South America ; to the hot spriogs of the
Geyser, whidi, impelled by elastic vapours, rise to an immense
height ; in a word, to all the effects of the mighty powers a( na-
ture, whidi have their seat in the interior of out pUnet. In
central America, or in the country of G-uatemala, and in the
FhilipfMOe I ale*, the natires make an essential difierencc between
water voknnoea and fire voleanoes (voicanet de agua y dejbego).
By the former name they designate the mountaJns, from which,
amid rit^ent earthquakes, subterranean waters issue from time
to time.
Without denying the comiecticm at the j^nomena just men-
tnmtd, it would yet appear expedient to ^e a more precise lan-
guage bo the f^yrical and OTyct^^nostical department of geo-
gnosy, in order to jwevent the apj^calicAi of the name of VcJcano,
sometimes to a mountain which is terminated by a permanent
fimiaee, and sometimes tn each subterranean cause of vtJcai^
fbenoraena. In the present state of the terrestrial globe, &e

Teyde, Tunguragua, and Cotopaxi. I have observed tfaeni
riang from the size of the lowest hills to 17,700 feet above the'
level of the sea. But close to these conical mountains, there al-
so occur perniaRent apertures, forming regular communications
with the interior of the earth, on long serrated chtuns, not at thtf
middle of thnr mural summit, but at their extremity, and near
the declivity. Of this kind is Pichincha, which rises between
the great ocean and the city of Quito, and which Bouguer's ba,'
rometrical formulae have long rendered celebrated. Such also
are the volcanoes which rise on the Steppe de los Pastes, which
b 10,000 feet high. All these summits, of varied forms, are
composed of trachyte, formerly named trap porphyry, a granii'
lar fissured rock, formed of glassy felspar and hornblende, and
in which augitc, mica, laminar felspar, and quartz, also occur.
In places where the evidences of the first eruption I might say
of the ancient volcanic scaffolding, are preserved entire, the iso-
lated conical mountain is surrounded, in the form of an amphi-
theatre, with a great wall, constructed of rocky strata, super-
imposed upon each other. These walls or dreumvallations are
tfie remains of craters o^ elevation, a phenomenon worthy of
attention, respecting which the first geologist of our times, M,
Leopold Von Buch, in his writings, irom which I have borrowed
several ideas stated in the present memcHT, has presetited such
interesting views.
The volcanoes which communicate with the atmosphere by
permanent apertures, the basaltic cones or domes of trachyte,
destitute of crater, sometimes low like Sarcouy, and sometimes
elevated like Chimborazo, form various groups. Comparative
geography shews us, on the one hand, small archipelagoes, and
entire systems of volcanic mountains, with their craters and cur-
rents of lava, resembling those of the Canary Islands, and the'
Azores ; and, on the other, mountains without craters, atid with-
out currents of lava, properly so called, as the Euganeans, and
the {Siebengebirge) seven mountains of Bonn. Moreover, it
shews us voJcanoes arranged in ^ngle or double lines, and extend-
ing to several hundreds of leagues, sometimes parallel to the axis
of the diain, as in Guatemala, Peru, and Java; sometimes cutting
it perpendicularly, as in the country of the Azteques, where tra-

This association of volcanoes, whether in isolated and rounded
groups, or in lon^tudint^ bands, demonstrates, in the most de-
cisive manner, that volcanic e£^£ts do not depend upon slight
causes existing near the surface of the earth, hut are phenomena
whose origin is to be found at a great depth in the interior of
the globe. The whole eastern part of the American continent,
which is poor in metals, is, in its present state, destitute of vol-
canic mountains, of masses of trachyte, and probably even basalt,,
with olivine. All the American volcanoes are collected together
in the chain of the Andes, which is situated in the part of that
ctmtinent opposite to Asia, and which extends, in the direction
of the meridians, over a ^ce of 1800 leagues. The whole
plain of Quito, of which Pichincha, Cotopaxi, and Tunguraqua
' form the cymes, is a volcanic focus. The subterranean Gre
escapes, sometimes by one, sometimes by another, of those aper-
tures which it has been customary to consider as distinct vol-
canoes. The progressive march of the fire in them has, for the
last three centuries, been irom north to south. The very earth-
quakes, which produce such terrible ravages in this part of the
world, afford remarkable proofs of the existence of subterraneaB
communications, not only with countries destitute of volcano^
which has been long known, but also between ignivomous
mountains placed at very great distances from each other.
Thi», in 1797, die volcano of Pasto, to the east of the course of
the Guaytara, vomited, unremittingly, for three months, a high
column of smoke. This column disappeared at the very mo-
ment, when, at a distance of rixty leagues, the great earthquake
of Riobamba, and the muddy eruption of Moya, destroyed
about forty thousand Indians. The sudden appearance of the
Island of Sabrina, to the east of the Azores, on the 30th Janu-
ary 1811, was announced by the dreadful earthquake, which,
at a mudi greater distance to the west, from May 1811 to June
1812, shook, almost without intermission, first the West India
Islands, then the plains of the Ohio and Misrisip[», and, lastly,
the coasts of Venezuela, utuated on the opposite side. Thirty
days after the total destruction of the city of Caraccas, the ex-
Volcanoes in the d^h-ent regions of the Earth. SS9
plosion of the volcano of St Vincent, in the Lesaer Antilles,
took place at a distance of ISO leagues. At the same moment
when this eruptioa happ«ied, on the SOth April 1811, a sub*
■teiranean noise was propagated, and carried terror over an ex-
tent of country of S200 square leagues. The inhabitants of the
-banks of the Apur^, at the confluence of the Rio Nula, as well
as Uiose of the sea coast, compared the noise to that produced
by the discharge of large pieces trf artillery. Now, from the
confluence trf the BJo Nula and Apure, by wWch I arrived at the
-Oronocco, to the volcano of St Vincent, the distance is 157
leagues in a straight line. This ntuse, which assuredly was not
propagated by the air, must have had its cause deep in the earth.
Its intensity was scarcely greater on the shores of the Antilles,
near the volcano in action, than in the interior of the country.
It would be useless to multiply examples; but in order to
-recall to mind a phenomenon which has acquired a historical
importancd with reference to Europe, I shall now mention the
famous earthquake of Lisbon. It took place on the 1st Novem-
ber 1755. Not only were the waters of the Swiss Lakes, and
of the sea on the coasts' of Sweden, violently a^tated ; but also
those of the sea around the eastern Antilles. At Martinique,
Antigua, and Barbadoes, where the tide does not commonly rise
more than eighteen inches, it suddenly rose twenty feet. All
these phenomena prove, that the subterranean powers manifest
themselves, either dynamically, by earthquakes, oi chemically,
by occasioning changeg in the form of volcanic eruptions. They
also demonstrate, that these powers act, not superficiaEy in the
outer crust of the earth, but at immense depths in the interior
of our planet, by crevices and unfilled veins, which lead to points
of the earth's surface, at the greatest distances from each other.
The more numerous the diver^tjes in the structure of volca>
noes, or in other words, of the elevations surrounding the canals
by which the mdted masses of the interior of the globe arrive
at its surface, so much the more important is it to submit this
structure to accurate measurements. The interest of these mea-
surements, which, in another part of the world, have formed
the object of my researches, increases if we consider that the
magmtude to be measured varies in several points. The phi-
loBi^ical examination of nature applies itself, in the viassitude
S30 Baron Humbokk on tfie Stmcturt and Ae^on tf
of jAeDomena, to connect the present with Ae pakt. To eata-
blisG a periodic^ return, or to fix the laws of pn^reMtve aod
▼aiiable phenomena, it is necessary \o have some vrll detennined
points of departure, observations made with csre, and wbicb,
bdng doanected with drtermined epochs, may furnish numeri-
cal compuifiODS. Had only the mean temperature of the stiD»-
qihere, and of the earth in difierent latitudes, m- the mean tempe-
rature of tbe barometer on the edge of the aea, been determined
from <me century to another, ve should have known in what pro-
portion the heat of climates has increased or diminished, and
whether or not tbe height of the atmosphere has uDdi«goi)e
changes. These points of comparison are required for tbe deeli-
Bation and inclioatioii of the magnetic needle, as w^ as for the
intensity of the electio-magnetic foives. If it be a praiseworthy
occupation for societies to follow, with assiduity, tbe cosuiic vicis-
eitudea of heat, of the pressure of the ur, and of tbe magnetic
directitm and intensity ; it is, oo tbe other hand, tbe duty of the
geok^Et, in determining the inequalities of the earUi'e sur&ce, to
take into consderation die change of he^ht of voL^iioes. What
I attempted at the time, in the mountaina of Mexico, at To-
lues, Nalihamput^^ and JoruUo, and in the Andes c^ Quito at
Fichincha, I have had an oj^rtnnity, since my return to En-
rope, of repeating several times at Vesuvius.
In 1779, Saussure measured that mountain at a period when
die two edges of the crater, die nwth-west and south-west, ap.
peared to him <^ equal height. He found their (^atton 609
toises above tbe level of the sea. The eruption <^ 1794 occs-
tdoned a filing in of tbe southern part, and au inequf^ty of iJk
edges of tbe crater which the most inexperienced eye dtrtin*
guisbes at a considerable distance. In 1805, M. von Buch, M.
Gay Lussac and myself, measured Vesuvius diree times. The
result of our operations was, that the heighi of the oerth
edge, the Bocea del Palo, which is of^site the Somma, i^eed
widi Saussure's measurement, but that the south edge was 75
toises lower than in 1773- The total elevation of the volcano,
towards tbe Torre del Greco, the «de towards wbicb tbe fin
had priocipalty directed its actioa for thirty years, had diminidi-
ed an eighth part. The cone of ashes is, to the total hei^ of
die mountaiB, on Vesuvius, as one to ten ; on tbe Petdc of Te>

■little beigbt, it has acted prmcipolly by it£ eummiL I suoceed-
ed lately not only in repeating my barometrical measurementa mi
Vesuvius, but also in ascending that mountain three times, in
order to take a cwnplete survey of all the edges of tbe taoter.
This undertaking is perhaps deserving of some interest, because
it dabmaes the period (^ the great eruptioDB from 1805 to 16S!i ;
W>d because it afibrds, perhaps, the only measurement of the
vtdcano, made with reference to all its parts, that has hilb«to
been published. It thews that the edges of the inmter, not only
in the places where tbey are vMbly composed of trachyte, as in
the Peak of Teneriffe, and io all the volcanoes of the chain of
tile Andes, but also every where else, present a phenomenon
much jncwe oonsbmt than had previously been supposed from olv
serva^DS hastily made. Simple angles of height, determined from
the same pcriat, answer much better for researches c^ this kind
than tiigonometiical and barometrical measurements, otherwise
nety coi]^>lete. According to (ny last determination, the north-
west edge <^ Vesuvius has not perhaps undergone any diminu.
tion of bdght «nce the lime of Saussure, that is to say for the
last f<«ty-nine years, and the south-east edge, on the Bosche Tr«.
Case side, which, in 1794, was 400 feet lower than the preced*
iog, has undergone a diminution of 10 toiset.
If the public journals, in describing the great eruptions, very
frequently relate that the form o£ Vesuvius has totdly changed,
and if these assertbns are oonfinned by the picturesque views
of that mountun which are punted at Naj^es, the cause of
error exists in the circumstance that the contour (^ the edges of
the crater is confounded with those of the heaps of scoriae which
are accidentally formed in the centre of the crater, on the bc^
tfna of the ignivomous mouth raised up by vapours. One of
these heaps, conaistiog of rapilli and scoriae, became gradually
visible in 1816 and 1818, above the south<east edge of the
crater. The eruption of FelH-uary 18£S iocreased it to such a
4^;ree, that it even exceeded the Rocca del Palo, or the north-
west edge of the crater, by 100 or 110 feet. In the last eru|>-

. A day after the cone of scorise, 400 feet bi^, bad fallen in,
when already small but numerous torrents of lava had flowed,
in the night of the S3d October, commenced the luminous ^up-
tion of ashes and rapilli. It lasted twelve days without inter-
ruption ; but it was more intense during the first four. All this
time, the detonations in the interior of the volcano were so vio-
lent, that the mere concussion of the air (for no commotion was
observed in the earth), cracked the ceilingj of the apartments in
the palace of Fortici. The villages of Uesina, Tone-del-Gfeco,
Torre d^l Anunziata, and Bosche-Tre-Case, whidi are close up.
on the mouDtaio, witnessed a remarkable phenomenon. The
atmosphere was so filled with ashes, that the wbole district woa
for several hours in the middle of the day enveloped in profouod
darkness. People used lanterns in the streets, as ofW) hi^)-
pens at Quito, during the eruptions of I^diincha. The inhabi-
tants never fled in such numbers. The torrents of lava were
much less dreaded than an eruption of ashes,— ^ phenomancm
which had not before been known to such a degree, and which,
from the obscure . tradition of the manner in which Heroula-
neum, Pompeii and Stabiie were destroyed, filled the imagination
of men with terrifying images.
The watery and hot vapour which shot up from the crater
during the eruption, and diffused itself in the atmo^here, fcM-m-
ed, on cooling, a thick cloud round the column of ashes and
flame which rose to liie height of 9000 feet. So rapid a «»-
densation of the vapours, and, as M. Gay Lussac has shewn, the
very formation of the cloud, augmented the electrical inten^y.

FUsbes issued from the column of ashes ia all direcUons, and
the thunder, which was eaaly distinguished fMm the notses of
the vdcano, was distinctly heard. In no other eruption was
the mamiescation of the electric powers so astonishing.
On the morning of the 26th October, a surprising noise was
heard, which seemed to arise from a torrent of boiling water thst
was ejected from the crater, and descended along the declivity of
the cone of the ashes. Mondcdli, the learned and zealous ob>
servn of the volcano, immediately discovered that an optical i1-
laaon had occasioned this erroneous rumour. The supposed
tcarent was a great heap of dry ashes, which issued from a
crevice in the upper edge of the crater. A drought which
^)read desolation in the fields, had preceded the eruption of Ve-
suvius. Toward the end of this phenomenon, the volcanic
thunder abarm which we have just been descritnng, occanoned an
extremely heavy and long continued rain. In all countries, the
cessation of an eruption is characterized by a similar -meteor.
So long as the present one lasted, the cone of ashes being gene-
rally enveloped with clouds, and the rain being heaviest in its
vicinity, torrents of mud were seen flowing aa all sides. -The
affrighted husbandman thought it was water, that, after ascend-
ing fi-om the bottom of the volcano, issued by the crater. The
gecJogist thought he discovered in it' sea water, or muddy
productions of the volcano, cm", to use the expression of the
French old systematic writers, products of an igno-aqueous li-
quefaction.
When the summit of the volcano, as is almost always the case
io the Andes, rises above the re^on of snow, or attains a hdght
double that of Etna, the snow, by melting and flowing toward
the lower regions, produces frequent and disastrous inunda-
dons. These are phenomena which the meteors connect with
the eruptions of volcanoes, and which are variously modified by
the height of the mountain, the extent of its summit covered with
perpetual snows, and the heating of the walls of the cone of
canders. They cannot at all be regarded as true volcanic phe-
nomena, being merely the effects, of such phenomena. In vast
cavities, sometimes on the declivity, somedmes at the foot of
volcanoes, are found subterranean lakes which communicate in
various ways with the alpine torrents. When the commotions

June 1698, the suniHiit of Carguaraizo, a mountain of the h«gb
of 18,000 fiaet, broke dowq, the whole oountry numd, to the ex-

of fishes from the volcano of Imbaburu.
I mention these iajcXA, because they throw some light oia the
diference which exists between the eruptions of dry ashes u)d
those of mud, wood, charcoal, or shells, serving to explain the
IbriBatioo of tufa and trass. The quantity of ashes throw*

the contrary assertions of Monticelli and Covelli, that the ashes
contain gold and nlver. According to my inquiries, the bed fit
ashes that fell during twelve days on the Bosch-Tre-Case sidc^
en the declivity of the cone, in the places where rapillo was
mingled with them, was only three feet deep, and in the plain,

on their huts ashes wluch the earth had vomited by t^ioiin^ up
OD ^ odes. On the contrary, in the periodical and ordinary
«xpk«i(HiB of volcanoes, the ashes terminate each parUal erup>
tion. Bendes, the younger Pliny's letter contains a passage,
which clearly shews, that, from the commencement, without the
influence of any cause that could have heaped them up, the dry
ashes thet fell directly from above, had attuned a height of four
or five feet. " The court," says he ia. the course of hb narra-
tive, ^hich had to be passed in order to enter the chamber
in which Pliny reposed, " was so filled with ashes and pumice,
that, if he had delayed bis ocnning out any longer, he would
have found the entrance shut up." In an inclosed space, like
that of a court, the action of the wind, by which the ashes are
collected, could not by any means have been very considerable.
I have ventured to interrupt my comparative examination of
volcanoes by particular observations made on Vesuvius, both on
account of the great interest which the last eruption has extuU
ed, and cm account of the remembrance of the catastrophe of
Pompeii and Herculaneum, which every con»derable fall of
■^es involuntarily brings to the mind. I have brought toge>
tber, in a supplement, all the elements of the barometrical mea-
suroneuts and notices respecting geological collections that I
have had an opportunity of making, towards the end of 162S, at
Vesuvius and in the Phlegrean fields, near Fouzzuola This small
collection, tc^ther with the rocks which I brought from the
£uganean mountains, and those which M. von Buch collected on
a journey to the valley of Flemme, betiveen Cavalere and Pre-
daszo, in the southern Tyrol, are deponted in the Royal Mu-
seum of Berlin, an establishment which, by its utility, perfectly
GorrespcradB to the noble intentions of the monarch, and of which,
the ge<^DOstical department, containiDg specimens Jrom the most
remote re^ns, is, in this re^>ect, superior to any collection of
this kind in existence.
We bftve been considering the form and acuon of those vol-
oanoes whi(^ keep uparegular communication with the interior
of the earth, by means of craters. Their summits are masses of
trachyte and lava, raised up by clastic powers, and traversed by
veins. The permanence of their action ^ves rise to the conclu-
sion, that thar structure is very complicated. They have, so
VdkoROet in the differmi regioM oftite Earth. 887
to speak, an iodividual cbsmcter, which remsins always the
same through long poiods. The neighbouring mountuns
most commonly afford entirely different products, lavaa of
leucite and felspar, obsidian and pumice, and basaltic masses
containing olivine. They belong to the most recent forma-
tions of the globe, and traverse nearly all the strata of the
secondary mountains. Their eruptions and their torrents of la-
va are of a more recent origin than our valleys. Their life, if
we may be permitted to make use of such an expression, de-
■ pends upon the mode and duration of their communication with
the interior of the earth. They frequently remain quiet for
ages, suddenly kindle again, and end with bnng solfaterras, es- ,
haling aqueous vapours, gases and acids. Sometimes, as in the
Peak of Teneriffe, ihrir summit has already become a laborato-
ry of regenerated sulphur ; while from their wdes there yet flow
great torrents of lava, basaltic and lithoid iu th«r lower parts,
vitreous, in the form of obsidian and pumice, in their upper
port, where the pressure is less.
Independently of these volcanoes provided with permanent
craters, there is another species of volcanic phenomena, which is
more rarely observed, but which is peculiarly calculated to throw
tight on gedogy, because it recalls the primitive world, or, in
other words, the most ancient revolutions of our globe. Moun-
tains of trachyte, opening of a sudden, vomit forth lava and
ashes, and ag^n shut perhaps for ever. Thisis what took place in
the gigantic Antisana, in the Chun of the Andes, and at Mount
Epomeus in the island of Ischia, in 1302. An eruption of this
kind sometimes takes place in the plains ; for example, on the
[Jain of Quito ; in Iceland, at a distance from Hecla ; in £u-
beus, in the fields of Lelant^. Many islands, suddenly ele-
vated from the bottom of the sea, belong to these transitory
phenom^ia. In these cases, the annmunication with the inte-
rior of the earth is not permanent ; the action ceases as soon as
the aperture of the canal of communication is closed anew.
Vans of basalt, greenstone, and porphyry, which in the diffamt
zones of the earth traverse almost all the formaUons, masses
of syenite, augite, porphyry and amygdaloid, which characte-
rize the newest strata of the tranulion, and the oldest strata of
the secondary rocks, have probably been formed in thia manner.

products of high furnaces, may have been united under a cry&.

ing under the form of lava from conical mountains, which have

standing the re^Kct due to so great a name, as to the numerical
accuracy of such a calculation, it is not the less probable, that
all volcanic phenomena arise from a ^gle cause, vhich is the
communication, constant or interrupted, that exists between the
interior of our planet and the external atmosphere. Elastic va-
pours, by thdr pressure, nuse through deep crevices the sub-
stances which are in a state of fusion, and which are oxidized.
Volcanoes are, so to speak, intermittent springs of earthy mat-
ters. The fiuid mixtures of metals, alkalies and earths, which
condense into currents of lava, flow gently and slowly, when,
on being reused up, they once find au issue. It was in this man-
ner that, according to Plato's Pfuedoa, the ancients represented
all the torrents of iire as emanations of the Pyriphlegeton.
To these comaderations may I be permitted to add another of
a bolder character. It is perhaps in the internal heat oS the
earth, a beat which is mdicated by experiments made with the
thermometer, and the phenomena of volcanoes, that the cause of
one of the most astonishing phenomena which the knowledge of
petrifactions presents to ua resides. Tropical forms of animals,
arborescent ferns, p^ms and bamboos, occur imbedded in the
frasen regions of the nor^. The primitive world every where
discloses to us a distribution of organic forms, which is in oppo-
ution to the presently existing state of climates. To solve so im-
portant a problem, recourte has be»i had to a great number of
hypotheses, such as the approach of a comet, the change of ob-
liquity of tha ecliptic, Uie increase of intensity of the solar heat.
Nene of these hypoUieses has been able to satisfy at the same
time the aMxooomer, the natur^ philosopher and the getJt^st,
As to my own oiuinon on the subject, I leave the earths axis in

dectro-magnetic intenNty, or the comniuiiicatJOD betwe^i the
internal and external parts of the globe.
When, in Uie primitive wqrld, tbe deeply fissured crust of ihe
earth exhaled heat by these apertures, perhaps during many
centuries, palms, arborescent ferns, and the animals of warm cli-
mates, lived in vast expanses f£ country. According to this sys-
tem of things, which I have already indicated in my work en-
titled KssM Geognoatigue sur le Gttement des Roches dans l^
deux Hemifpkeres, the temperature of volcanoes is the same as
that of the interior of the earth, and the same cause which now
produces such frightful ravages, would formerly have made the
richest vegetation to spring in every zone, from the newly oxi-
dised envelope of the earth, and from the deeply fissured strata
of rocks.
If, in order to account for the distribution of the tropical
(arms that occur buried in the northern regions of tbe globe, it
is assumed that elephants covered with long hair, now immersed
in the polar ice, were oii^nally natives of those climates, and
that forms resembling the same principal type, such as that of
lions and lynxes, may have lived at the same time in very dif^
ferenc climates, such a mode of explanation would yet be inap-
plicable to the vegetable productions. For reasons which ve-
getable phy»ology discloses, palms, bananas, and arborescent '
monocotyledonous plants, are unable to support the cold of tbe
northern countries ; and in the geognostical problem which we
are here examining, it appears to me difficult to separate the
plants from the animals ; the same explanation ought to embrace
the two forms.
At the end id this memcnr, I have added to the facts coQected
in countries the most remote from each other, some purely hypo-
thetical suppositions *. Tbe philosophical study of nature rises
above the wants of descriptive natural history ; it does not conaat
of the mere accumulation of isolated observations. May it one
day be permitted to tbe curious and active mind of man, to dart
from the present into the future, to interpret what cannot yet be
known with preduon, and amuse itself with the geognostical
faUes of antiquity, which are in our days reproduced under va-
rious f<Hins.

J. HK results of the observations of this pbeaooiaion made du-

same subject, given at much length in the Appendix to my for-
mer Narrative, I shall here confine myself to the mention of a
few hiief deductions from a careful examination of our registers
at Bear Lake.
The observations were made without intermisEion for six soo-
cessive months, in the years 1835-6, and again in 1826-7.
My opinion, recorded in my former Narrative "f-, that the dif-
ferent positionsof the Aurora have a con^derable influence upon
the directioD of the magnetic needle, has been repeatedly con-
firmed during our residence at Bear Lake. It was also remark-
ed, that, from whatever p(nnt the ilow of light, or, in other words,
the motion of the aurora proceeded, if that motion was rapid,
the nearest end of the needle was drawn towards that point,
almost simultaneously with the commencement of the motion.
A careful review of the daily registers of the appearance of
the aurora has led me to form the following general conclu-
sions: 1st, That brilliant and active coiruscadons of the aurora
borealis cause a deflection of the needle almost invariably, if
they appear through a hazy atmosphere, and if the prismatic
colours are exhibited in the beams or arches. When, on the
contrary, the atmosphere is clear, and the aurora presents a
steady dense light, of a yellow colour, and without motion, the
needle is often unaffected by its appearance.
2(?, That the aurora is generally most active when it seems to
have emerged from a cloud near the earth.
3d, When the aurora is very active, a haziness is very gene-
rally perceptible about the corruscations, though the other parts
of the sky may be free from haze or cloud.

iffi. That the nearest end of the needle is drawn towards the
punt from whence the motion of the aurora proceeds, and that
its deflectionB are greatest when the motion is most n(pid,— the
effect being the some whether the aoticm flows along a low arch
at one that crosses the zenith.
Bth, That a low state of temperature seems faTourahle for the
production of brilliant and active corruscations, it being seldom
that we witnessed any that were much agitated,< or that the pris-
matic tints w^e very apparent when the temperature was above
zero.
Bth, That the comiscations were less frequently visible be-
tween the first quarter day, and the full mocNQ, than in any other
period of the lumination, and that they were most Dumerous be-
tween the third quarter and the new moon •,
7th, That the appearance of the aurora was registered at
Bear Lake in 18S5-S6, 343 times, without any sound having
been heard to att^id its motions.
8^ The height of the aurora was not determined by actual
observation, but its having been seen mi several occasions to il-
luminate the under surface of some dense clouds, is conclusive
that its elevation could not have been very great. When Dr
Richardson and Mr Kendall made their excursion on Bear
Lake, in the spring of 1896, the former saw the aurora very
bTilliant and active, displaying prismatic colours in a cloudless
sky (on S3d April) ; while Mr Kendall, who was watching at
the time, by agreement, for its appearance, did not see any
corruscation, though he was only twenty miles distant from Dr
Richardson.
9tt, The gold-leaf electrometer, which was kept in the obser-
vatory, ;was never affected by the appearance of the aurora.
\Otk, On four occatdons, the corruscations of the aurora were
seen very distinctly before the day-light had dis^peared, and
we often perceived the clouds in the day-time disposed in streams
and arches, such as the aurora assumes.
* The proportion of comiscations seea at these periods, from the month
(^'October 1825 to April 1826, was 38 to 129. The mnonligbt b«dng «trong
between the first quarter and the tiill mooD at those hours when we mcae
paiticutarlj watched fur the Aurora, may, perhaps, account for our not hav-
ing seen its corruscations so otten during this part of the lunation.

The opinions I have ventured to advance above, are at va-
riance with the conclusi(m8 drawn by Captains Parry and Fos-
ter, irom their observations at Port Bowen, — those officers in-
ferring that the aurora does not influence the motion of the
needle : but the discrepancy may be perhaps explained by the
difference in activity and altitude of the aurora in the two places.
I have stated that the needle is most affected when the aurora is
very active, and displays the prismatic colours. Captains Parry
and Foster have informed me, that the aurora seen at Pent
Bowen was generally at a low altitude, without much motion in
its parts, and never exhibiting the vivid prismatic colours, or the
rapid streams of light, which are so ft^uently recorded in our
renters, of its appearance at Fort Enterprise and Fort Frank-
lin. At both these places, we as often witnessed the corrusca^
Uons crossing the zenith, as at any other altitude, and under
such a variety bf forms, and in such rapid motion, as to baffle
description.
From the difference in the appearance and activity of the au-
lota at Port Bowen, and Forts Enterprise and Franklin, an in-
- ference may be deduced that the parallel of 66° N. is more &•
vourable for observing this phenomenon, and its eflect on the
needle, than a higher northern latitude.
A Sketch of the Climate of the Mediterranean, with Remarks on
its Medical Topography ; being the result of Five Yeari
Observation. By the late William Black, Esq. Surgeon,
Royal Navy; and communicated by Dr Black of Bolton
in Lancashire.
J. HE great basin of the Mediterranean, from its lying between
countries differing so remarkably in their several localities and
productions, has its general climate impressed with a mixed cha-
racter, which it is as interesting to study, as it is important to
analyse. Though the average climate for twelve months maybe
called equable, which is the character it has in England, yet
there is, perhaps, no similar extent of water and coast where
great climatorial vicissitudes are so plentifully produced by dif-
S44 Mr Black on the CUmate
ferences of situation and changes of wind. The Father of Me-
teorology, as well as of Physic, in his treatise on Airs, Watos,
and Localities, has fmthfully recorded the influence of winds
aad situation on the constitution of the atmosphere ; and, from
every observaticHi which I have been enabled to make, it ap-
pears, that, amidst the wrecks and changes which the face of
every country on the shores of this sea has experienced, the
same characteristic climate, general and particular, exists, as it
did, upwards of twenty-two centuries ago; and that the obsa-
vations of Hippocrates may still be considered the best synopMs
of the meteorology of this part of the world.
' Equable as the general climate has been remained to be; yet,
if one day is compared often with another, or one part even with
another of the same day, the atmospheric vicissitude is some-
times very considerable ; and particulaiiy as respects the humi-
dity of the air. Such changes are most sen^bly felt on the
shores of Europe, and on tKe south coasts of Greece and Tur-
key in Asia -, and it is on a line, equally distant fi-om Africa and
Europe, that such variable states <^ the atmos[di^« are least
perceptible. Malta is, therefiire, thought to be most out a( the
sphere of this vicissitude, yet a great change of wind at this
place is attended with.vcry sensible changes of its climate; and
it is by no means that desirable residence for an invalid whidi it
is thought by many to be.
A moist or damp atmosphere is certiunly to be avmded by
the majority of invalids ; and that of England is so much blam-
ed in this respect, as to be accounted the chief cause of the pul-
monary complaints prevalent in the kingdom. The moisture
. of the English atmosphere, except under-the influence of rare
localities, is perhaps less than that of Malta ; for Humboldt has
found, by hydrometrica! observations, the superior humidity of
the atmosphere as we approach the equator. Invalids who ge-
nerally resort to Malta and Italy, are of relaxed fibred of body ;
and one argument against the salubrity of the last mentioned
place for them, is, that, in removing from England, they avoid
little, if any, atmospheric humidity ; added to which, they re-
move to an increased temperature, which must'stilt farther in-
crease the relaxing effects derived from humidity. In corrobo-
ration of this, we every day see people who, by chronic disease,

have been reduced to an oifeebled and very relaxed state of bo-
dy, sent from the Mediterranean to England with the bappieat
effect ; while it is an eatablisbed rule in the fleet, to remove every .
one immediately from the climate who betrays any indjnent
symptoms of (AtbiEds. I have also seen cases of chronic and sy-
phiUtic rheumadsm deriving, particularly, the gr^test beieflt
' from a return to England. But, to resume the natural history
of tbe subject, — Though the exteomve surface of this mid-
land' sea, lying between tbe 3lBt and 45th degrees of north lati-
tude, and embradng about 40° of longitude, has a general cli-
mate, constituted by the regular succession of seasons, like alt
other ge<^aphical surfaces which have a marked summer aod
winter ; yet the several places bordering on and within its am[de
circuit, have climates peculiar to themselves. These peculiari-
ties are compounded of the general Mediterranean climate at any
given season of the year, and of the apteral influence <J the
winds prevailing at tbe time, conjoined ^tb the nature of the
land which surrounds the place, - and over which these winds
pre^ously blow ; whether the sea, and what extent of it, lies in
the course of the winds ; and-wbether it is situated on the north
or south shore of the mainland or island. Before, however, no-
ticing the few remarks which I have personally made on the
particular topography of the climate, I shall flrst give a sum-
mary view of the great modifying, if not elementary, principles
ot Heat or Temperalure, Humidity, the Winds, and Electri-
dtjf, as observed in tbe Mediterranean, for the space of more
than five years,
Tefoperature. — It will be seen, from the table annexed, that
the average temperature of the year at noon is considerably
above what is called temperate in England, b^i^ forthree years
very near &f; and from the thermometer being re^stered al-
ways on board in an airy and shaded fdtuation, it may correctly
be inferred that the temperature on land is a few dorses high-
er. Equable and mild as this annual heat is, yet the changes
from day to day, or from morning to night, are sometimes as
great as they occur in England, during tbe same space of time.
The average heat for the summer of three years never exceeded
81°, nor was it below 74° ; and, in the winter months, it never

descended below 54.6," which is iC above the mean annual tempe-
rature at GoqMTt, as observed by Dr Burney *. This extreme
monthly temperature of 54.6° In February 18!i4, was attiibuted
to the strong niHrtberly winds which for ten days prevailed at
Smyrna ; and as the average for the same season in the other
two years was nearly two degrees higher, I ^ould conuder that
tbey best expressed the corresponding temperature in the two
years in which my daily raster was not kept The highest
range observed at noon was 86°, winch was off Algiers, in Au-
gust 182^ and tlie lowest was 41°, at Smyrna, in the evening
at eight, in January 18S7. The range of the summer nHHitbs
never exceeded 11°, while that of the other nnrnths wasof)«i as
much as S6°. For three months after the summer scdstice. the
beat on board was steady above 76° ; and when the winds at this
season are scanty, the thermometer is sometimes above 90" ffli
shore. If it were not that the great heats of summer exhaust
the sources of humidity, the atmosphere would be felt the mmst-
est during the greatest heat. We should, also, have the hea-
viest dews at night; but the reverberation from the heated sur-
face of the earth often keeps the vapour suspended tjirough tile
night, though clouds may be precifntated in the higher and cooler
regions.
Be«des the characteristic temperature of the season, the heat
' -at any place is moreover greatly afiected by the winds at the
Ume ; thus, the westerly winds will not disturb much the regu-
lar increase or fall for the season, and the easterly but little;
while the winds from the north, before the melting of the snows
on the Appenines and on the Chain of Pindus, in May and
June, will lower the temperature many degrees on the south
coasts of Italy and the Morea. The south and south-east winds
will, on the other hand, as remarkably elevate the thermometer;
especially if they have blown steadily for a few days, and not
over a widely intervening extent of sea. The effect of warm
winds, immediately succeeding those from the north or a cold
quarter, has often been observed \o be productive of severe ca-

Hwmidi^. — The hy^tnnetrical conditioa of the atmosphere
is an important oligect of attention in any dimate, and it exerts
a great modifying influence in that of the Mediterranean. Thu
state of the lur is very mudi affected by the direction of the
winds, as well as by the temperature at the time ; it also nearly
observes variati<His corresponding with the temperature, being
generally, in its sensible qualities, drier as the air is warmer, and
moister as it is cooler. An exception to this concomitancy, how-
ever, exists in the currents of air over an extent of sea being al-
ways mtnat, whether in summer or winter ; thou^, it must also
be added, that the Sirocco, if felt moist at first on the northern
shores of the Mediterranean, becomes drier if it continues for
some days ; and it sometimes will arrive there in aU that arid
state which is experienced 6n the coasts of Barbary and Egypt.
Winds off land free from marshes, are dry in summer ; and
they are steadily moist, if they blow from snowy surfaces in the
advanced part of the cold seascm. They are therefore moist,
from moist places, in winter, under many changes of the wind;
jbr the temperature never descends so low as to reduce the evs..
poration to a nullity, but ranges between those degrees on the
scale where the dew fcaat is very near the point of saturation.
At Modon, in the south of the Morea, the humidity in aunw
mer is much influenced by the prevailing winds. After the
snow has melted on Pindus, Olympus, and Mount Taygetus,
the land winds are dry, and the south winds are mrast. If these
last have blown for a length of time, they become drier, etipB-
cially if they are of the Sirocco, and even if tbey have blown
over the sea long in any direction ; fcv it appears the longer
winds blow over the sea, if it does not get agitated, the evapora-
tion becomes less, and it is much greater after rains or heavy
dews, which seem to form a thin stratum of fresh water on the
surface, liable to be instantly evaporated on the first increase of
240 Mr Black on the CUtnate
hjgrometrical capaaty. At Patrasso and Lapanto, the rmm*
tiasu in the atroosf^erical humidity' are veiy trifling, from the
winds, in most direcbone, sweejMng over the land, which in-
fluences the proximate effect of th^ previous condition. Many
other examples ought illustrate the efiect that surfaces, over
which the winds blow, have on the humidity of the atmo6|diere.
Thus I have found, in coasting round the Morea in summer,
when the wind was from a great extent of sea, that the air was
always damp. Off Navarino, it was extremely so, when it hlew
from any otJier point but over the Morea. In the course of a
voyage, the same winds will be felt changing their hygrcmetri-
cal cooditioa with the different localities over which they travd.
Off Navarino, a north-west wind will be moist, while, under the
lee of Zante, it will be found dry. In running from Cape An-
gdo to the d'Oro Passage, a northerly wind has been found diy,
mth all the arid and bare Cyclades to windward ; while, after
getting through the Passage, the same wind has become exces-
ravely damp, and continued bo until the Gulf of Smyrna has
been made, when it again became dry,-— it blowing over Mi- '
tyletw, aiter having previously traversed an unknown extent of
terra'flrma.
Temperature, d^iends not so much on surrounding localities,
aa on the seaaon ; while humidity is move affected by the surface
over which the wind blows than by the season. Even in the
taUer part of summer, whrai the land becomes a great reverbe-
rator of heat, arising, in a ^»o^derable d^ee, from the decay of
its verdant vegetation, the temperature of the air sufe^ no great
change from a change of wind ; yet its aqueous condition will be
muoh aflected. In calculating, then, on the dryness or musture
of the air, the point of the compass from which the wind blows
is not so mud) to be conadered, as the surface, land or sea, over
whidi it travels, and the extent of that surface, with the inter-
vening locality, if any exist. At Malta, I have observed tlie
hygrometer stand tlie highest, with the wind from the north ;
and the lowest, with a wind varying from S. to ^. in the months
of July and August. From the Meteorolo^cal Table, it will
be observed that the proportion of f^r weather is much ^cater
than it is in Britain ; and that the rainy and showery days
(which were registered rainjf, when rain fell even for a few
houis, and showery, if one shower happened during the 24), do

uot amouDt to ax veAn on an annual avecf^ for three years.
It must be added, however, that the rains, when they do occur,
are generally veiy heavy ; and Uiat the dews, in fiue unclouded
weatb^, are cojnous *.
Wwids.— From the observations of fi^e years, I have found
\ik prevailing winds to be from tiie northward ; and particularly
when the weather assumes a steady constitution, and the sum-
mer season has fairly set in. In the winter, the winds do not
appear to blow particularly from any quarter of the compass,
but veer very much between the NE. and S. In the ^r
weather <^ summer, variahle and light winds mostly prevail,
and in winter they are less frequent. After the hilly country
in Greece is covered with snow, if the winds blow from any di-
rection more than another, it is from the S. and SE. ; but, when
the snow is dissolving in the spring, the vicissitudes of both
wind and temperature are very great. The Sirocoo, at this last
period, though it seldom blows long at a time, is not so warm as
it is in the beginning of winter, and differs very little from a
moderate breeze from any other pdnt, in consequence of its not
Uowisg kmg enough to bring on its wings the milder tempe-
rature of the south ; and therefore it is moist, cold, and relaxing.
The greatest number of cases of fever which I have witnessed
on board ship on this station, followed the prevalence <rf S.SE.
or light varuble winds in May and June, at Corfu ; niule, in
October of the same year, when diarrhcea prevailed, the winds
were northerly. At Nspoli di Romania, I found cynanche and
other affecticms of the mucous membranes particularly prevail,
after keen ncvdierly winds, with a clear sky, had been preceded
by occaoonal light Sirocco winds.
To diew how localities will at times affect the temperature of
the mnde, in opposition to the r^ular effects of the season, I
have found the north wind off the coast of Calabria to be hot
and dry in the latter end of September ; while the wind, the
next day, fixim the S.SK. or SW. was excessively damp, and
accompanied with a cloudy sky. This anomaly arose from the

•mall quantity of rain that had yet fallen in Italy, not being
auffiflient to cool tbe surface of the land ; while, on the other
hand, this hot and dry wind had acquired much humidity iitHn
the sea, before it retrograded and was repelled by the succeed-
ing southerly currents. The Sirocco or SE. wind ia ao imput-
ant one in any part of tbe Mediterranean ; and di£fer^it opi-
nions have been formed as to its dryness and moisture. . The
fact is, that these qualities are entirdy governed by the surfaces
over which it blows, before reaching the place of observatjcm.
Thus it is m<nst and warm, as felt on the coasts of Greece and
Italy; because its exalted temperature imbibes much vapour
from the sea, after it leaves the northern ^ores of Africa, where
it is hot and dry. Nowhere can such a wind be felt in the inte-
rior or the northward of Europe ; for there is nowhere in Eu-
rope such a country as the Lybian and Arabian deserts, so fiat,
■0 dry, and eo little capable of imparting to its winds any thing
like tbe electric condition of the land and atmosphere of other
countries •.
Electridhf. — This is a modifying element in the constitution
of every chmate ; and, though less appreciated than beat or bu>
midity, it no doubt performs a most important part in all aU
moepbaic changes ; if it is not an essential agent in every modi-
fication of cloud, dew, and vapour. The infiuences at heat and
humidity are much more easUy defined than those of electricity ;
which, though in constant operation, only ensiles us to draw
any satisfactory induction from its great and palpable phenome-
na. Evaporation was long thought to be a fertile source of elec-
triaty ; and Fouillet ■)■ has lately proved this t^nion to be well
founded, as well as that chemical and v^etable change is ac-
companied by electrical disturbance.

^ihe Meditemmean. %&\
Of the grand pheDomena of Uiis subtle yet mighty agent, the
Meditemmean exhilnts every year biaay coqs[»cuoub examples ;
and especially when the sumniei- caiiadtulicm of the weathor
breaks up for the season. During the winter and spring months,
tiiunder and lightning do not often occur ; but I have never
observed the Geason to change during the decrement of tempera-
ture, without more or less of electrical phenomena taking place,
and of^ to a frequent and great extent In the months of
August and September, when the temperature thus be^ns to
fall, and the winds have blown from the north, and over any ex-
tent of sea, for some days, the atmosphere wiU become oft^n ob-
scured with irr^ularly formed clouds to leeward, — the wind
iwill next change or abate, and, during the evening and night,
succesnve evolutions of electricity will be se«i on the upper
part of the newly deposited clouds, which are precipitated, one
after another, from the muddy and misty atmosphere above.
Rain next succeeds without thunder ; and in twenty-four hours
the wind will again change steadily to the northward, with a
dear sky, fine weather, and a permanent fall of the thermome-
ter. If tliese phenomena are witnessed on the coasts of Italy
asxA Greece, the depo^Uon of clouds takes place over the bi^
lands ; and the electrical tranHtions are accompanied with thun-
der and forked lightning, — often exhilHting the sublimest in-
stances of elem^atal commotion.
I always remarked Uie develop«n»it of electric light to be
from the upper outline ofthe newly precipitated strata <tf clouds;
and where these fresh charges of electric light were successively
transmitted from cloud to vapour, they, no doubt, were accom- -
panied with mudi evolution of caloric, from the vapour parting
with its latent or constituent heat. The direct preliminary con-
dition of such pbentunena ^eemed to be a wind from' the sea, or
fnHn Uie south. Such winds as the Sirocco are always attended
with imperfectly formed clouds, or a hazy atmo^here ; and, on
the converse, I have often seen a change of wind to the south and
east from the northward, completely dissolve the r^ular clouds,
and render the air muddy and hazy. These remarkable elec-
tric phenomena will more particularly happen, if these south-
east or south winds have blown for some time, and have been
immediately preceded by northerly winds, or winds off the
SSa Mr Black on the Climate .
land. The reason of such phenomena not occurring at once, on
a change of wind to the southward, arises, it seems, from the
iirst of the southerly wind bang only that body of the air which
had lately blown from the oppodte or northerly quarter, and
wluch must precede the true current of the south, with its cha^
racteristic properties. It ia for this reason, that we often found
a cold southerly or south-east wind at sea, where no localities
could have immediately influenced the -temperature, such as at
Malta and off' Ci^ Spartinento. From this cause, also, - the
longer a Sirocco blows, the drier it becomes ; and, in the vicinity
of such devated land as the Albanian ridge of mounttuns, this
partial change to warmth with mmsture, in the Sirocco or south
wind, may be considered indicative, in the fall of the year, of a
thunder storm, or the lesser electrical phenomena, with a fall of
rain, and a change of wind.
It is evident,' also, that besides the humidity and heat, which
form a great difference between winds proceeding from the op-
posite points of north and south, there is something else con-
nected with the air and the surfaces over which its currents
pass, that affects the animal system in that remarkable man-
ner whicli is witnessed during a Sirocco or southerly wind.
On a change taking place to this direction, the inhabitants of a
place, and those who have lived but a short time in it,. sennUy
experience a languor and relaxation of both the mental and phy-
sical energies ; while diseases, depending on laxity of fibre or
emunctory, become at the same time, aggravated. Thus dys-
peptic complaints, chrtmic catarrh, and cynanche, mtdce no pro-
gress towards recovery ; and if the Sirocco blows immediately
after a cool northerly breeze, it often proves the cause of de-
veloping such diseases.
What this depr«geing something is, it may at present be pre-
mature to dogmatize about. There is an era, however, to which
medical science is fast hastenit^, when this will no doubt beex-
plmned ;. since the progress, which all the auxiliary sciences are
making, point out to us that such a consummation will h^pen.
To ducidate siHnewhat this intricate portion of our subject, we
shall make the best use of the data we possessj and the observa-
tioDs we have made.
As far back as 1770, it was conjectured by Brydon the tou^
i^the Medifetranean. 258
list, that what has since been called the nervous energy, must be
■nalogoUB to the electric fluid ; and that the nerves served for
the transmission of birth. He illustrated his theory by the ef-
fects produced on the animal system by the Sirocco, or winds
flther partially or wholly deficient of their natural electricity.
By the researches of Abemethy, Phillips, Bichat and Le G^-
Ims, this conjecture of Brydon's has been much supported, so
far as the analogy between the nervous enei^ and the galTanic
fluid is concerned. It is well ascertained, that in damp or hazy
weather none of the electric fluid can be collected ; and, as the
air of the Sirocco can receive no electrical im[H^gnation, 1:^:
sweeping over a dry and flat desert of sand ; so the mcnsture,'
which it acquires in its passage subsequently over the sea, nitist
give it a strong absorbing and conducting power for electricity.
The consequence is, that this moist wind, coming in contact
with bodies possessed of more electricity, will rob them of part
of thdr electric fluid, until an equilibrium is effected between
the earth and the lur,— the grand final cause of all electrical
phenomena. Now, as the human body readily parts with and
receives electricity, and as an object, on the surface of the earth,
must be a ready point for the transmission of the fluid, it can-
not be supposed that it is phyucally exempt irom those electrical
influences which such winds produce on the rest of matter, but
must lose a portion of tho constituent fluid it previously posses-
Bed, — which loss is followed by all those Byni]|)toms of depressed
energy already noticed.
The animal body, then, inay be deprived by the atmosphere];
in a series of degrees, of that energy which, if it is not the pro-
duce of the living functions, is at least the natural portion of
electricity which the body possesses in common with surround-
ing objects at the time. Life may even be extinguished from
the highest operation of this cause, as often happens during
thunder storms, when no marks of physical injury can be de-
tected.
The diflerent electric states of the difler^it winds are pretty
well ascertwned by stationary declrometers ; and, though I had
none r^ularly in my possei^ion, I found natural phenomena
themselves to aflbrd both excellent and beautiful proofs of this
quality in the several winds. The summer of 1835 presented
354 Mr Black on the CUmate
very sati^ctory examples of the important part wliich the elec-
tric fluid performs in meteorological jAenomena, espemlly when
the coDBtitutioD of the cloudless sky of summer b^;ati to be de-
ranged. As this change happened on the coasts of Albania
and the Morea, it commenced by the north-east winds gettbg
stronger, and \eering more about from one point to another,
with corresponding variations of temperatura A calm, alter-
nated with faint southerly breezes, succeeded, which was fol-
lowed by a thick atmosphere at sunset, lightning over the Mo-
rea, and rain after which it cleared up, and a north-west wind
steadily prevailed. A few days afterwards off the Bay of Pre-
vesa, the northerly wind fell, the fitmosphere thickened, and the
wind agiun sprang up from the south-east, light at first, and
' freshed through the night. About the following sunrise, in-
side the Corfu Channel, one of the most (errific tliunder storms
commenced that can well be imagined ; which, after floods of
rain, lasting, with slight intermissions, for several hours, termi-
nated by a sudden change of wind to the northward, and sooa
afierwards a dear, cool atmosphere succeeded, with the wind
from the north-west for some days.
Though more or less varied, the summer seasons, as I have
before remarked, always break up in the above manner, and sub-
^de into a cool temperature. Whatever occaaons the change
of wind, whether it be from the land becoming a greater rever-
berator of the solar heat, arinng from the decay of its verdure
and f<Jiage, and so rarefying greatly the superincumbent stra-
tum of air, by which the cooler currents from the sea are elidted,
it is very evident that the phenomena, described as attending
such changes of weather, result proximately from the collision
of clouds or strata of vapour differently electrified as to each
other, or from the electric condition of the clouds being in' a mi-
nut or pius state, as respects the subjacent land and mountains.
For the better under^anding of what takes place during these
electric collJsioDS, it is necessary to ascertain what respective
body of clouds is pbu or minus electrified ; or whether it is the
hi^ land, or the atmospheric stratum impinged against it by
' the Sirocco, which gives or receives electricity during the resto>.
ratton of that equilibrium which ensues. The experiments
which have shewn the negative electric state of the Sirocco, are
i^ihe Mediterranean. Xfifi
lughly corroborated by the following .connderatitHis. In the
first place, as the earth is the centre and source of electricity, as
well as of gravitiUion, and over which the former flaid must be
<Ustributed nearly in an equal manner, it b not pn^ble that
any of the prominent parts of the earth can ever be lf»ig in a
minus state, compared with the incumbent atmosphere, when
not in much motion ; although the land rem^ing in its natural
electric state may present, in certain places, points of attraction
for the discharge of any clouds or vapour passing over it, and
being in a posiuve state of impregnation. The winds from the
sea and the southward seem, however, not to contain sufficient
electridty to balance that of the land, which they meet with on
the northern shores of the Mediterranean, or that of the winds,
which blow £rom any extent of hilly land to the norlhvard ; for
they travel over a surface of water, through which they can re-
ceive little electric impregilation ; while they become charged
with mudi humidity, which renders them very susceptible of re-
ceiving electricity, wherever it is presented in a comjKwatively
positive condition. In tracing these winds to the S. and SE.,
they are found traversing boundless plains, hot, sandy, and arid,
wh^ice no electric fluid can be extricated, nor can they be held
to contain more than keeps their constituent gases together.
Arriving in a dry and non-conducting state on the northern
coasts of Africa, these southerly currents afterwards sweep over
the intermediate sea, and soon, from their high temperature, be-
come charged with humidity, which, from want of electric fluid,
never gets embodied into regular clouds, but the atmosphere
k>oks thick, hazy, and muddy ; the sudden appearance of which
during a northeriy wind, is always a sure indication of a change
to the southward in a Bhort time. Having reached the coasts
of Italy and Greece, and coming in contact with the elevated
mount^ns, these currunts of vapour assume the form of regular
clouds; and, collecting, exhibit the transmission of electric fluid
to the succeeding currents of humid air ; which, often suddenly
condensing into rain, rapidly increase the south-easterly influx
towards the same points, and create such a mass of negative at.
mospbere, that all the grander phenomena of thunder, lightning,
and torrents of rain, are developed.
Besides these illustrative instances of the relative electric states
356 Mr Block on the CUmale
of the opposite winds above mentioned, analogous phenomeoa
ai-e scaneQoies observed at sea, and out of the immediate influ-
ence of the land. Thus a wind, blowing from the Dorthem
.shores of the Mediterranean, may be in perfect equilibrium with
the land it leaves ; yet, when it encounters the southerly current
at sea, will be in a relatively positive state of electtiaty. The
c<Hisequence of this collision will be, a transference of the fluid
from the north to the south curr^t ; and according to the ex~
tent of the electric difference between them, will be the amount
of the resulting phenomena. From the observations of five
years, I have always found, that, when electrical phenomena ap-
peared, a change of wind from N. to S., or from oppo»te points
near to the meridional line, invariably occurred. One diflerence
has been noticed in the character of these phenomena, that, when
they were developed in the vicinity of high land, thunder ac-
companied them ; but, at sea, it seldom or never occurred, — the
transfer of the electric fluid, in this last eituation, appearing to
take place in a more gradual and less violent manner, than when
the peaks of mountains facilitated those local accumulations,
whose disturbance creates such intense results.
As a general observation on this port of the meteta^l^^ of
U>e Mediterranean, it may be inferred, that winds or currents of
, vi^UT, of some continuance, from an extent of sea, are nega-
tively charged with electricity ; and those from the land, and
especially from hilly countries, are relatively in apositive condi-
tion.
During the period in which I have been in the eastern section
of the Mediterranean, abundant opportunities have occurred of
witnessing the effects of localities on the temperature and humi-
dity of the winds, even when they continued to blow ftom the
same quarter of the horizon ; as well as of observing how the
climates of particular places are affected liy the nature and direc-
tion of the winds, and the atmospherical impregnations prevail-
ing at the time. These opportunities have resulted from being
often one day to the northward, and the next to the southward,
of Iftnd, with the continuance of the same wind ; at anotli^ day,
with a great sci^ of sea, and on the following one with an ex-
tent of land, in the direction of the same wind ; while frequent
visits to different places and anchorages, in different seasons of
ofQK MeSUmmean. 257
the year, have furnished me with some personal observations on
their respective climates. I shall therefore conclude this sketch
with a few climatorial notices of such places as may he more fre-
quently visited by the traveller, and by ships of war and com-
merce, reserving to a future opportunity a more ample detail of
this department of Mediterranean topography.
Zonte.— Of all the anchorages in the Ionian seas, that of
Zante Roads seems to be the most eligible in point of salubrity ;
as the moisture and relaxing qualities of the Sirocco are there
greatly qualified by the wind first passing over the east end of
the island. There is also no great extent of land or sea in im-
mediate cotmectim with the port ; from which circumstance, the
shifting of the wind from one point to another is not attended
with very sensible changes of heat or mcnsture ; and, unless the
calms are prevalent at night in summer, which they seldom are,
there is very little humidity or dew precipitated: The breezes
Jrom the N. and NE. are very firequent and refreshing, and ge-
nerally set in early in the forenoon, as the sea-breeze, and Bub-
ade at night during the warm season of the yetu*. This ancho-
rage is also free from any malaria.
Sta. Maura. — The next anchorage tu that of the Roads of
Zante, in pcnnt of healthiness in the hot season of the year, is
the south anchorage of this island, the andent I^ucadia. Being
bounded by the high land of the island on the west^ and by that
of the Acamanian hills to the eastward, this aDc)ionige baa the
winds dry from these opposite directions ; while the currents of
air in the direction of the channel, whether they are N. or S.,
are more moist. Even when the wind blows from the S. and
SE., it is moderate ; and, from the lands and islands, whi(^
lock in the anchorage, and are devoid of wood and sources of
humidity, the place is never very damp, or pernicious by night.
The winds, however, blow seldomer from these last directicms
than from the opposite points, whence they are cool, dry, and
refreshing, in the hot months. In the direction of N. and N£.,
these is mudi low land, and even stagnant water ; but such an
e(t^it of sea and dry land intervenes, that their influence is not
much to be dreaded.

In the north anchorage, however, of this uland, I should
think the effluvia from the lake near the town would prove in-
■alubtiouS] It being extensive, and also near to the port. This
anchorage is seldom visited by any of our fleet.
Fouquevilte relates, that, on the approach of those appear-
ances in the ur, and the fiery colour of the sun, which precede
the earthquakes to which this island is subject, the female inha-
. faitants are seized with a species of hysteric convuluons, called
miterico ; but I have no personal knowledge of such affec-
tions *.
Cephabmia.- — Judging from the ntuation of the extensive
harbour of this island, I am inclined to think it a rather healthy
anchorage. The great height and extent c£ sun burnt surface
aa the one ^de, over which the wind oomes as if from an oven,
when it blows in that direction, the low and small extent of land
across which tlie Sirocco has only to ptus before it reaches the
port, and the great scc^ of sea over which the southerly winds
previously travel, constitute, however, some demerits worthy of
consideration, and counterbalance the other presumable advan-
tages. The stagnant head of the harbour, beyond the long
bridge, must, be^des, prove a source of miasmatic effluvia to
the crews of those vessels of a smaller class that refit there and
carera. I have seen the first onset of the Sirocco down the har-
bour ruse the thermometer ten degrees. The south-east wind
in pasang over the island of Zante, is much intsvased in tem-
perature and dryness during the summer seaaon ; and in the
vint^* it is thereby rendered colder, if not more moist. These
rdaxing SE. winds very t^ten produce severe catarrhs, espe>
dally if cold winds have previoudy prev^ed.
Corfu. — This is an tmchorage where a gtxKl deal of fever oc-
curs in the hot mtmths; and \ have witnessed its prevalence for
sever^ yeara. In this season the winds are l^t, or calms pre-
via ; and at nig^t, the dews are g^oerally -vtxj heavy. When
the winds Uow, it may eamly be observed, from the nature of
the sunouoding localities, tluit they wil nnbihe febrific exhak-

sing over their surfaces. The above is also the direction whence
the land breeze in the night reaches the aRchorsge ; and I have
often perceived the same fetid smell accompanying the lirat of
the evening breeze, nhich I have expenenced at Port Boyaj,
Jamuca, at MeauBa, and off the Italian ^mared.
As to the mcdus operandi of these land breeiws, impregnated
with marsh vapour, it is difficult to say whether they act by
suddenly repreesing the perspiration, from tbw bong charged
with humidity, and of a relatively low temperature, or by d&-
prassiog OF impuring the nervous ener^es in the same manner
as the SiroCco does ; or whether tiiey may even operate ' in
both ways on the animal syston. It is, moreovei*, wcil known,
that fever is more often devekiped in the n^t time, . or in the
evening, when the energiei of the body are most exhausted ffom
labour, fatigue, and the excitement of a hot day i vlule I have
particularly remarked, that its invasion in this climate is always
declared by symptoms of exhaustion and depression. These aw
syncope, sudden failure of muscular strength, and dbturbance
of the reparative funcUons, with the expuluon upwards or down-
wards, ftx)m the primK vik, of what the argans cannot digest or
assimilate. The adynamic state of the moving powera is ob-
served in the pallor of the surface, and the depressed state of
the pulse. During the summers in which I have seen fevers
preval«it at this anchorage, southerly and g£. winds occurred
by day, and at night it was either calm with heavy dewi, or
else it was a land breeze possessed of the qualities above men-
tioned. The other localities of Corfu, if not so un&vourable,
possess no entire exception from the unhealthy impregnaiianE
which they impart to winds arriving tU the anchorage. From
the eastward, there cannot be any cool sea breeze by day in
the summer months ; as the expanse of sea n only aevan mUes
between the island and the bwe and parched land of Alboaia,
while the greatest sur&ce of sea is down the chamiel, which lies
in a SE. and southerly direction, whence the breezes are wvm,
moist, and relaxing.
The change of the seaaon, however, changes the infiucnoe of

locality on the winds of the place, as it does on those of other
places. For six months in the year, the snow on the gigantic
mountains of Albania is a fruitful source of cold and moisture
to the winds sweeping over them ; and, therefore, in the early
part of summer (in April and May] a change of wind from the
S.SE. or SW., to the direction of these mountiuns, b attended
with a sudden and great decrement of temperature ; wh'Je a
contrary effect as remarkably obt^ns on s reverse of the prior
phenomena. The chief complaints, resulting from such changes
of wind, are catarrhal and mucous affections, which are qiiite
endemical in such seasons. When the snow is melted, the
breeze from the mountains would be not only warm, hut dry ;
but as seven miles of water int^vene, the breeze always gains a
degree of humidity before it arrives at the anchorage. These
easterly winds are, however, not frequent during the hot months;
but if they gently prevtul, in the evening a haze generally settles
down on the tops and shoulders of these mount^ns, occaeduned
by the reverberation from their heated surfaces preventing the
deposition of dew fn^ the humid strata of the incumbent at-
mosphere.
Ithaai. — This is a good anchorage in the hot season ; for
though the island is sterile, it is dry, and possesses few or no
sources of hurtful exhalations.
Acamimia. — The whole coast about Missolonghi, and the>'
mouth of the ancient Achelous, is very unhealtJiy, especially
during the autumnal months ; as the marshy and low lands in
this diluvial re^n are an extennve bed for the production
of noxious exhalations ; and I would recommend no vessels to
anchor by night near this coast in that season of the year. In
May 18S6, a good deal of fever made its appearance on this
coast, and which was declared to be of the typhoid variety. It
was communicated to one of our vesaeie of war. Whether the
disease was solely to be attributed to the marsh exhalations, or
partly to the destitution and misery which were spread over the
neighbourhood after the fall of Missolonghi, I have not been
able to determine.

sive qualitgr of the Sirocco at Corfu; though, while it blows,
the atmosphere by day is hazy, streaked, and disturbed; and
by night, it is often clear from the deposition of dew, if calm,
or the mr is beset with light and regular clouds, wbich are agtun
converted into haze, by the next day's sun. It is late in the
spring before the high land in northern Greece gets sufficiently
heated to make the land breeze feel warm, or even temperate ;
and I have seen from Corfu, in the beginning of June, the
whole range of Findus deeply coated with snow. As summer
advances, the winds get light and variabie, and are accompanied
by a warm and sultry sky in the day time, followed by heavy
dews at night.
In the Gwlf of Koioky^ia, ancieutly Loconia, duiing the
summer, the breeze sets up the gulf in the morning, and dies
away towards night; and I have never veiified the effects of (my
malarious winds at night, even when they regularly set in from
the land,'in the months of August and September. One of our
sloops of war, however, experienced a good deal of fever in thisi
gulf in the autumn of 18S5.
The inhabitants of the naghbouring parts of Laconia are
much subject to boils and ulcers at this reason of the year, and
they generally looked unhealthy.
Cerigo is a high lying island, and is well exposed to the winds
in all directions. I found fevers, however, here very preva-
lent in August 18S5; but the disease was principally amraig
the Greek soldiers. The inhabitants, in the absence of all ma-
larious ground, attribute their attacks of fever to changes of
wind, from the north to the southward. In Fort St Nicolo the
temp^ature was 86°, and the breeze followed the course of the
sun in the middle of the above month ; though at sea the winds
were more fixed to one point. Remittents and agues continued
to prevail here in the latter part of the above year, even towards
the interior of the island. This ^ckness was more remark-
able, as there is no observable source of miasma, the surface be-
ing dry, and free from wood, and the above changes of wind

meteorologic phenomenon. The season broke up rather e^tiy
this year by thuoder storms.
I have observed, on arriving in the Gulf of Napoli di Ro~
mania, in the winter and spring settsonB, from Malta, a great de-
pression of temperature, with a continuance of the same north«-
]y winds, owing in same meamre to the anchorage being com-
pletdy surrounded with snowy mountains. The winds passing
over theee in the day-time, become saturated with humitSty,
' and the air being at that tempa'ature in wliich the range ffl>in
the point ai saturation to the dew pcnnt is very limited, viz. be-
tween 45° to 54° : this humidity is easily precipitated.
Though I have visited the site of the famous lake of Lema,
on the western side of the gulf, I cannot say whether the Hy-
dn Boake, whose namerous heads Hercules repeatiedly cut off,
yet exists under the less palpable form of th« no less venomous
miasma; but I ^ould think, from looal appearances, tbatev«a
Hercules himsdf might yet find enou^ to combat with the de-
mon of the place.
At JUUo there are many sources of Febrific miasnata ; but
when the winds bknv from the northward, they only traverse
the pranontary of the high and dry land, which forms the east
shore of the harbour. To the south of the anchorage, however,
there is a good deal of low and marshy land, over which a {6g,
inomti^ and evening, in c^m weadier , geoemlly rests ; and
from wlocfa the occastonaj breezes must arrive, charged nidi
BODch exhibikin. In the same southerly directions there are
aome hot aulj^ureous springs, which, whatever their influence
may roAy be, are eareftilly avoided, as hot-beds cf ^c&ness, by
the inhatutantB. It is well known that nckness has raged at
times severely in this Jsbaid ; and the andents seemed to have
been aware of the insidubrity of the pait mentioned, ^ all the
rams of antiquity are found to the northward, or on the eKire
devaCed luid. In the autumn of 18S4, a fever broke out, *nd
carried off a ^^«t m wy of the inhabitWAB. It was said to have
been brought fnun Candia by some Gretk i^iugees, wbo ptin-

In May 18S6, 1 found a good deal of fever amoog Uie Greek
troops at Athens; but there were sufficient causes productive of
such distempers among them, without the lud of any oialariouB
breezes from the marshy Cephiseus, or the swamps in the course
of the IlysBUB, towards the Pireus.
At Sm^jyia the winters are generally temperate, and Uie low.
est point of the Uiermometer observed by me, during the seasm
of 18S&-7, bynight as well ss by day, in the open air, on board,
was not below 41° ; between which and the highest 72° ; there
were, however, many vicissitudes, both as to himiidity and tem-
perature. The changes of weather are not so suddenly marked
here as among the Ionian islwids, or on the coasts of Greece.
The influence of locality is also rematkable ; the south-east
wind having not much of the character of the Sirocco, and the
Btmo^here, at the time, not being bazy, nor accompanied by
those sensations, which are felt during a Sirpcco on the coasts of
Italy and Greece. As a general observation on the winter sea-
son of the year, there is less variation in the tempemtuie and
hy^vmetry of the air than to tiie westvrard. The wet points
are south-west and west, and the difference of temperature be-
tween south-east and north is at limes considetahte. At the
greatest depresMon of temperature, catarrhal qomplaiDts prevail-
ed much <Hi shore, as well as on board, and were tUteoded, in
many cases, with mudi fever. The winds v&k then oorth-east
and east, in which direction the land in the diatasce was covered
with snow.
Id tlie UMxuh of October 1824, while visiting the coasts of
Asia Minor, and being off the Troades, some intermittents made
their appearance among the crew <^ the Euryalus, and I was
led to attribute them to local influences. The plains of old
Ilium are low and e&tenuve, and at a abort distance ftom the
beach is the marshy course of the Scamander ; and ia the vita-
njty of the ruins, and moFe to the int^jor, is the wider and pcu
ludal course of the Smou; both of which ore very probable •ourecB
of febriflc exhalations. The average temperature in the above

It IB needless to speak of the beautiful and breezy Bay of
Naples, the refreshing salubrity of which is proTerbial ; but re-
markable vicissitudes of clinate nevertheless occur on changes
of wind from off the sea to the land ; which are again materially
modlSed by the winds sweeping over the Appenines, when co-
vered with snow, or reverberating the heat of an autumnal sun.

Malta is perhaps as free as any ^tua^n in the Mediterra-
nean from terrestrial sources of unhealthiness ; and Valetta en-
joys a happy immunity from the injurious effects resulting from
changes of wind, being utuated to the north side, and having its
Sirocco winds ameliorated by their first traversing the surface of
the island. In winter the northerly winds are always rendered
more temperate, by their previous passage over the intervening
sea, after they leave the cdd surface of Europe ; white along
the southward of Greece, those winds are then felt in all thar
raiginal fri^dity. The opposite results obtain in the latter part
of summer ; the northerly winds are cool at Malta, and hot and
dry on the south shores of Greece. I have seen, in March, a
fall of hail stones on the island, about an inch in depth ; and at
this time of the year, the winds often, from their great and fre~
quent changes, lose their distinctive characters ; thus, the south-
east, or Sirocco, has been found cloudy, cold and wet ; and the
westerly and gouth-westerly winds neither mild nor warm,^all
these amnnalies arising from the frequent changes, tossing back-
wards and forwards the same mass of atmosphere and clouds.
Atgiera. — Though the plague rages siMDetiines at this place,
yet its natural situation keeps it free from any endemial causes
<^ sickness ; and it may be reckoned a healthy place ; owing to
the hi^ land to the southward tempering the heat and dry-
ness of the winds of the desert. All winds here frran east,
through north to west, are damp or foggy in the summw sea-
son.
In August 1834, an interesUng crancidence, between the ap-
pearance of nineteen cases of febrile commotion and a sudden'
change of wind, took place off Bona, in the Euiyalus frigate.

The previous winds for some days bad been moist, and from the
northward, when they were interrupted for two hours by a strong
Sirocco, accompanied by a great rise of temperature ; and so arid
was the wind, that any thing moist or damp dried in it as quick-
ly as if it had been exposed to the fife. The marked attacks of
fever were simultaneous almost with the Sirocco, and the}' dis-
appeared in a short time, from the use of gentle depletion, and
with the quickly succeeding change of weather.
Towards the east point of the northern coast of Africa, the
■ sand from the desert often reaches the Mediterranean, and gives
a light yellowish hazy tint to the atmosphere. At Alexandria,
with the breeze at SW. by S., warm and dry, I have seen the
finely pulverulent sands create a complete haze, and partially
obecure the sun. I first supposed the haze arose from the hu-
midity evaporated from the small extent of sea, and the course
d the Nile ; but finding portions of yellow sand collected on se-
veral exposed places of the ship, I was soon convinced of the true
nature of the pbeaomenoQ. Achangeof wind, at Alexandria, in
February 1883, from the NE. to SW. by S., produced an in-
craase of the temperature from 56° to 76*, being SO d^;rees in
cmeday. * • »
Conclusion by Dr B. .
To g^ve a complete history and estimate of the climate of the
Mediterranean, as connected with health and the developement
vS disease, it would be necessary to refer to an extenave set of
good rasters, and to bring forward an outline of the diseases
which afiect the various natums inhabiting its shores, as well as
those which seafaring people and strangers experience. But as
this was an extent of inquiry beyond the opportunities of the late
author, the preceding sketch professes only to detiul the ample
meteorological phenomena whidi came under his observation ;
and the few inductions which be has drawn, may serve to illus-
trate the more obvious connections between health and climate.
In giving the sketch to the public, the editor has thought to
contribute some facts to meteorok^cal kksux, as well as to ful-
fil the supposed wishes of one, of whom afiection might truly
say

Obiervaiions on the Arborisationa in Dendrite Caicedontf, or
Mocha Stone. By A». Bbomgmiabt *.
FOR a long time, those irregular filaments observed in the
Vftiieties of agate commonly called Mobs Agates, were believed to
be confervce. Daubenton was the first who made known his
opinion on ttds subject -f- ; and while he admitted the arboriza-
tions of agates to be mere infiltrations, he thought he distin-
guished ia certfun moss agates real vegetables, and in particular
confervee and mosses. The figures which he has published of
these objects are too imperfect to enable us to form any idea
respecting the forms which he intended to represent, nor have
I been able to find any thing resembling them amimg the speci-
mens preserved either in the old collection of the Jardin des
* The tbllowing obaervatioti on moclu' stone occur in mj System of Mine-
niogf.
" The dendritic calcedonies, or mochs-Btonefl, are much prized at ornuoen-
Ul Btonea. The arborizatioiiB, as already mentioned, are black, brown, or
oreai. The blade as the most common, and most distinct : the red, on the
contisiy, ue rarer, and arc leas distinct, and are named aaraSinu, from theie-
sunblance ot the dendritic delineations to coral ; and the green are rare, and
much esteemed. These arborizations appear in some cases to be owing to
iron, in others to manganese, iron, and mineral olL Ueutens, Von MoU,
Daubenton, and latelj Lens, Blunenboch, and Dr MacCulloch, malnfaitn
Uiat many of them are of a true vegetable nature. Deutena says, that If the
plants contained in calcedon; aie extracted, and the fragments thrown on

calcedonj sometimes conti^s browa and green moss.

FknteB, (M* in that of the Academie dea Sciences. Ab (o the
conferroid filamentB, a great number of specimens pnaent them,
which have the appearance of those figured by Daubenton ; but
we shall presently see what opinion is to be formed respecting
those alleged conferee. After Daubenton, Blumenbach, in a
letter to the Baron de Moll, of which an extract is inserted in
the Annals of Philosc^hy *, admits, that, although he bad until
then rejected the presence of vegetables in calcedonies, he was
persuaded that these stones sometimes contain actual vegetables,
p^bably of the nature of confervse. He says he observed some
in specimens from IcelandandCatharinenhurg, andadds, that, in
an agate which had belonged to a Japanese prin^, he hkd re-
cogmsed the fructificatitm of an unknown plant, having a consi-
derable resemblance to that of Sporganium erectum. This o^
nion, to which the name of so celebrated a naturalist might give
authority, has unfortunately never been farther developed by its
author, who has neither published a detailed description nor
figures of the vegetables which he thought he had distinguished
in these calcedonies.
The same ppinion has been supported by Dr AlacCulloch -f*,
who allies that calcedonies contain arborizations c^ two kinds,
the <«ie arising from the presence of vegetables, the other formed
by mineral infiltrations. He asserts that these two kinds may
be distinguished both by their external characters and by their
chemical nature, the former always becoming black when boiled
in sulphuric acid, while the others retain th^r ori^ual charact«',
and produce a slight effervesceace. The same naturalist says he
sometimes observed articulations in these filaments ; but unfor-
tunately the figures which he has ^ven of these objects are not
sufficiently enlarged, and are consequently insuffici^t. If re-
ference be made to tbese figures, it b certainly difficult to refuse
admitting in some of them portions of vegetables even more com.
plicated than conferve, such as Jungermannise. But these in-
filtrations sometimes emulate the external forms of a vegetable
to such a degree, that one must be well acquainted with the
plants of these families not to be deceived with respect to tbem.

Anxious, therefore, to assure myself of the nature of these al-
1^^ v^etables, I examiDed a considerable number of moss
agates, beWging either to public collections or to those of pri-
vate individuals in Paris. I observed them not with a nmple
lens, but with Amici's excellent microscope ; of which, however,
I only employed the lov minifying powers of from 50 to about
100 diameters. In mtHV cases, the traDBparency of these agates
enabled me to see distinctly, at least in certain points, the dis.
potation of the filaments, and I wax enabled to assure myself,
not only that they had nune c^ die characters of plants of the
family of Confervte, or of any other plant, but that they even
presented characters whit^ proved them to be mere infiltrations,
and not v^etables. I have represented, in figs. 7 and 8 of
Plate I. of my work on Fossil Plants, the two forms under
which these infiltrati<xis most commonly presmted themselves.
Fig. 7 shews the disposition which the brown infiltratuHis of the
nearly c^Mque moss agates generally adopt. The filaments,
which are very irregular as to their size and mode of diviatw,
are variously bulged. They are pretty distinctly defined, with>
out any nebulonty around them, and appear formed by knotty
matter, of a dark-brown colour, filling numerous filiform and
irr^ular canals, distributed without order in the calcedcmy.
These infiltrations are very often irregularly anastomosed, whidi
precludes all idea of a oonfervcud plant, unce in the only cases in
which similar anastomoses exist among the confervs, they
give rise to a very irregular neUworit, as in the Sj/drodgfction,
or to a mode of reticulation, irr^ulat it is true, but very dis.
tincl from that of these infiltrations, and such as is observed in
the coDJugata, particularly in the Z^^tema gem^amm. The .
only plants I know, whose irregular onastonuMes resemble, in
same respects, those presented by the infiltration in qtiestiou, are
in the genus Rhizomorpha, a geoui which, in no other reelect,
has any resemblance to the infiltration of agates.
These brown infiltrations are the most frequent, but the most
Ksnarkable, oa account of their agreeable appearance, and their
resemUance, at first «ght, to confervse, are the green infitera-
tions. The matter, which forms them, appears much thinner
than that of the brown infiltrations, so that it has, as it were,
tinged the calcedooy to some distance from the small canals in
D.n.llzedbyGOOg[C
Dendritic Cakedomf, or MochaSbme. 371
wfakh the infiltration has been fonned. There is also always
seen, in the middle of the filaments, a more opaque line jmw-
duced by a matter of a deeper green. This line appears to rp-
preaent the small canal itself which traverses the calcedony. It
is irregularly bulged at intervals, and the greenish nebulosity,
formed by the infiltration of the colouring substance in the
■tone itself, has followed all the irregularities of this can^.
The more or less linear or stron^y mammillated form of these
. infiltratioiu^ and their greater or less opacity, appear to depend
upon the extent of these canals, and the quantity of colouring
matter which was contuned by them. The aspect of these in-
filirations also, the frequent anastomoses which they form, and
thar irregularity, preclude all idea of vegetable origin. Some
gelatinous aaA tremdloid plants, such as the Linckite, Meso-
gbHa, &c. have somewhat of this i^pearance, but they never af-
fect this filamentary and anastomosing disposition, nor does ex-
anunation with the microsn^ enable us to detect any analogy ;
'for, with a magnifying power such as that which we employed,
these plants presented characters of structure which immedtale-
ly distinguished them.
These two forme of infiltration nre those which are of most
frequent occurrence in moss agates. I have observed another
in a part at a slice filled with brown infiltrations, f^ich left
srane doubts on my mind as to its origin. It presents a regu-
larity in the filaments of which it is ccnnposed, and in their anode
of divicdon, which' pretty distinctly su^jests the idea of several
confervK, and, in particular, of certain species of the genus
Bangia, such as B. atrtmrens *. It is, however, possible, that
it may be nothing ^se than a more r^ular infiltratioD, produ-
ced by very minute and regularly ramified canals. What would
induce me to think so, is the mode of distributian of the opaque
nutter toward the centre of the filaments. In the coafervmd
plants, to which these filaments nught be compared, the gra-
nular and coloured opaque matter fills the whole cavity of a thin
and membranous tube. The transparent part, which is desti-
tute of this granular matter, thoefore forms on the edges bat a
narrow border, produced by the wall of the tube. Here, aa the

contrary, the opaque matter occupies a narrow c«tnJ line,
which appears to be th* canal itself by which the ccmunag
substance has penetrated ; and all round this centml thread
there occurs a senutransparent layer, much thicker than s metD-
branous tube would be, and which appears, as in the green in-
filtratioiis, to be the resiilt of die infiltration <A the cdouring
matter into the very substance of the stone. Notwithstanding
its greater reseml^nce to a plant, I therefore am still of ojh-
. nioD that it is a mere infiltration. Thus the inquiries whidi t
have made, hare not, as yet, enabled roe to discover in odoe-
dimies well characterized pUnts, whether belonging to the
group <^ Conferva: car to any other family.
As to tbe mode of formation of these infiltratioi» in the inte-
rior of calcedony, it forms no part of my object to account for
it; aoA I leave to mineralc^;iata to discuss the manner in which
the small canals which are filled by the colouring matter tax
formed, the solid or gelatinous state of the stone at this period,
and the nature of the niatter introduced into it. My only object
was to shew, that, iu most cases, if not in all, the vegetable kiog^
dom has nothing to do with these infiltrations ; in other jwords,
that they do not represent vt^tables, and that the'ir mode of
Iwanching even proves that the canals which occupy their axis,
do not owe th«r origin to conf»Toid filaments, whidi these infil-
tratitms may afterwards have envdoped, and caused to disap-
pear. I know that the presence of confervoid vegetables in hot
spra^, whidb generally oontwn mlica in solutim, might have
accounted iar their presence in these straies ; but the v^etablev
<^ hot springs are ostnllatoriss, a kind of confeme, which, mors-
than any other, differs from the infiltraticms (tf calcedony, in
having its filaments always simple, and most commonly straight,
or only sH^tly flexuous.*— ^Tut. des Vegetaux Foaniet, \en

On the Occurrence of Fossil Remains <^ Mammalia in the Coal
Formation of the Canton of Zurich.
JU. ScHiNTz, M. D., in August 1827, gave a. general ac*
count to the Helvetic Society of Natural Science, of the foaal
remains of mammifera discovered in the coel mines of the Can-
ton of Zurich, and described the rocks in which the coal occurs..
Bones have already been found in five places in the Canton it-
self, or near its frontiers, viz. at Ht^nach, on the Ltdie of
Zurich ; at El^ near Buchberg, in the Canton of Schaffhausen ;
neac Sedmatten on the frontiers of Thurgau and near Sprei-
taiboch in Argau. A considerable quantity of the rematng
of mammifera have been found at Kopfnacfa, in the course of the
kst nx years. They consist of two kinds of teeth of the
narrow-toothed mastodon, of which three fore-teeth, and one'
from the bottom of the mouth, were presented to the Sodety ;
beavers teetli*, and those of two ruminaung animals, of which
one is scarcely larger than the teeth of the small musk, and
another belongs to a species of deer, were also exhibited. The
whole country of Kopfoach belongs to the tertiary formation.
A regular series of sandstone, with limestone, containing much
clsy, gives to the whole a marly and eaaly decomposable
property. This molasse formation occupies neariy the wh<^ qf
the great basin lying between the Alps and Jura, extending
about 100 miles in length from the Lake of Constance to the
I^e of Annecy, and from 10 to 30 in breadth, and presents
mountain chains from 1000 to 2000 feet high, and sometimes
1000 in breadth. Its depth may be about 3000 feet It is in
this formation that all the coal mines that are woriced occur;
and in these mines the uiimal remains have been found.
In the coal mine of Elgg, which has been worked about forty
years, and of which the gallery is about 300 fathoms long, there
have been found &agments of another species of mastodon,
which does not correspond to any of those described by Cuvier,
and which has only a distant resemblance in form to the great
mastodon. The upper part of the gallery consists of a fine
granular brecaa, the lower part or floor of a soft sandstone, con-

another entirely unknown, without doubt the fore tooth of a pa-
t^ydomatoua animaL The two teeth were presented, but none
1^ the members present knew the latter. The presence of the
pakeotheriuni proves, in Cuvier^s opinion, that this coal forroa-
tion is older than has hitherto been supposed ; for he considers
the palfeotheriuins as animals of very ancient creations.
There were also presented a jaw and some bones of an unde-
temUDed E^iecies of mostodoo, taken from a coUiery near Buch-

animals, much more raiely remuns of v^tables. Trunks o£
luge trees are di^nctly seen only at Buchberg. At Eopfnach
there is nothing but drcular leaver and at Elgg aatas indistinct
fibres of ro<4a. The state of earbtmization, however, may be the
cause that the v^;etable substances are less distinct, since even
the hardest bones are so easily iHvken.

ter ftota I>*vrii MiLNR, Esq. A.M. St. to Profesor Jame-
My Dear Sir,
x\. PUEHOUBDON occurred in tins neighbourhood, a few days
since, of which perhaps the following short account may not be
uoaoceptable to you. Having yourself visited a jurt of the
banks of the river Whitadder, you are probably aware that
t^y consist entirely of the new red sandstone, with its marl and
gypsum. From the peculiar nature of this formation, as well
as the very prevailing abundance of clay, the soil is in general
extremely friable^ and readily crumbles to pieces by the united
action of the weather and the river. The strata rise towards
tiie north ; and as the course of the Whitadder is from west to
east, its banks, from this circumstance, are, on the south nde,
generally very steep, often perpendicular : while aa the north
saABf they ^ope towards its edge with a much less precipitous
and more regular descent. It is owing to the same geological
conformation of the strata, that, with hardly any exception, dl
the rivulets, which flow into the Whitadder, are to be found on
the north side, as the rains which fall upon the land on the op-
posite banks, taking their direction from the inclination of the
strata, h«ve rather a tendency to retire from the rirer. These
rivulets have, in many places, worn away the friable soil com-
po^ng the banks, to such an extent, that deep and narrow ra-
vines have been formed, and consequently long and lofty ridges,
connsting entirely of marl strata. Opposite to a small' mill,
atuated on the south bank of the Whitadder, called HuttOB'
Mill, there wse one of these ridges which owes its origin to the
cauee just mentioned, ona side of it being watered by a little
brook usually dry in the summer, and the other side partly run-
ning, along the edge of the river Whitadder.
This ridge rose to a height of about 120 feet almve the level
of the river j its length at the top may have been about 60 feet,
and at the base 300 feet. Upcm Tuesday last, 9SA July, at

S76 Mr D. Milne on the Slip and Breaking up
three o'clock in the afternoon, this immense mass separated from
its basis. The greatest part was impelled forward about 150
feet, and the whole hill was reot and broken asunder into a
thousand pieces. Not a vestige remains of the former arrange-
ment of the strata, and the channel of the river lias been entire-
ly choked with the aggregated ruins.
From the account which I have ^ven of the ^tuation of
this hill or ridge, it is easy to discover the cause of the
slip. During the dry and warm months of the early part of
summer, large fissures had been formed in the clay and
marly soil of which it is composed. During the .late nun,
which fell in such abundance throughout every part of the
country, these cracks or fissures were, of course, suddenly fill-
ed with water ; and all who are aware of the immense force
with which a column of water acts, where it is of any consider-
able height, will understand how it may have contributed to
loosen the friable texture of the strata. But the chief cause of
this extraordinary slip I conceive to have been the rivulet al-
ready mentioned, which skirts the north side of the ridge, and
by which, in fact, the ridge has in the course of time been form-
ed. When this stream became swollen into a rapid torrent by
the rains, and overflowed its narrow channel, the dry state of
the soil allowed the water to percolate down freely through the
marl strata, dipping towards the Whitadder ; and thus, both by
means of its physical force, and by rendering slippery the sur-
face of the mari rock on which the ridge rested, it caused the
superincumbent mass to slide down the declivity. The conse-
quences of the operation of this very simple agent were incon-
ceivably tremendous. An entire hill, consisting of solid strata,
propelled forward from its basis, and severed into fragments,
must have formed a spectacle of the most appalling grandeur.
The noise of the crash must have been very considerable ; as a
young woman, working in the garden of the mill on the oppo-
site mde of the river, was so terrified that she sought her safety
in-flight, and attracted the neighbours to the spot by her screams.
About eighteen months ago a small slip took place also upon
this side of the river, very near the spot I am now describing,
and arisingfrom the same cause. And I may remark, that, from
the peculiar nature and position of the strata compo^ng the
Googk
of Strata on Me Banks oflhe Wkitadder. 9^'t
north banka of the Whitadder, it is probable that this neigh-
bourhood will very frequently witness a repetition of the phe-
nomena similar to the one which has so recently occurred. I
remtun, my dear sir, yours very faithfully,
D. Milne.

EwamiitatKm ^ the Experiments hitherto puhlUhed on Subter-
ranean Temperature, together with Experwients and Ittqui-
riea relative to this Examination. By M. L. Cokdies,
Member of the Royal Academy of Sciences, and Professor
of Geology in the Garden of Plants".
J. HIS expeiiments that have been hitherto published on sub-
terranean temperature are of two kinds.
Some of them have for their object to examine the tempera-
ture of common springs, of rivers which issue directly trtym the
earth in cert^n countries, of artificial fountains, of waters issuing
from caves or galleries of dnunage, intended for the drying of
great mining works. These experiments are not numerous, nor,
as we shall afterwards shew, do they furnish any other than ^
proximattve data.
* The object of the other experiments has been to determine the
temperature of natural or artificial cavities, by means of which
we are enabled to penetrate into the bowels of the earth. These
experiments are numerous, and lead to results which have been
r^arded as precise. They have been pushed as far as from 1300
to I6OO feet. The following is a brief account of them :
In France, we have the experiments made in the caves of the
Observatory of Paris, which were commenced about 150 years
ago, and which have been perfected by M. Arago ; those made
by Gensanne f, in the metallic mines of Giromagny, about the
middle of the last century ; and those in 1806 by M, Daubui»^

those of M. de Tr^ra, in 1805, 1806, 1807, and 181/t§. In
Great Britain, we have to mention numerous expmments made
from 1815 to the present day, by Mr Lean, MrRede, and especial-
ly Mr W. Fox, in the copper and lead mines of Cornwall and De-
vobshire ; and by Messrs Bald, Dunn, and Fenwick, in the coal
mines of the north of England %. Lastly, we must also include
into the number those made by M. de Humboldt in several mines
in Peru and Mexico •*,
The number of mines in which these different observations have
been made is upwards of forty ; that of the individual markings
of temperature is about three hundred.
Nearly two thirds of these markings of temperature have be«n
wade from the ur contained in subterranean eavitMS, w)d most
of the others frcffis the water which pree^its itself in so many

farmer, they all result from observations made on descending into
the mines for a short time.

vities i and, as the results have been similar to those vbich I am
about to examine, the inferences at which I shall arrive aM
equally applicable to them.
Such are the experiments whose merits we have to appreciate ;
and in doing tliis criucism has nothing to n^ect. As it is pro-
posed definitively to ^ply to the great the inferences deduced
from the small, it is obvious that the lightest errors will have a
pnidt^ous influence upon what is to be inferred regarding tb«
entire maas of the globe. Thus, for example, proceeding from
the approximate law which is deduced from the experiments hi-
therto published, one degree of Fahrenheit of emv more for a
depth of 160 feet, in a given country, will raise to 1 ,600 feet (nearly
half a qiuner of a let^ue), the point at which it is to be presumed
that the temperature of boiling water exists under the place of
observation. These oonsidc»itioti9 will be a BufBdent apcdogy
for the details into which I shall sometimes be obliged to'enter.
By means of the precsuticms to which I have bad recourse, I
trust that my own experimentB may be regarded as sufficiently
accurate. Most of them were made in three coal mines in France,
very distant from one another, which I selected as presenting the
most favourable circum stances, and which are : 1st, the mine of
Littry, situated eight miles W. SW. of Bayeux, in the Departs
ment of the Calvados, and of which the openings have an eleva-
tion of about 200 feet above the sea ; Sdly, the mine of Ded«e,
situated seven and a half miles to the north of the city of that
name, and of the banks of the Loire, in the Department of the
Nievre, and of which the elevatitm ^x>ve the sea is about 490
feet ; ddly, the mine of Carmeaux, utuated in the Department of
the Tarn, eight miles to the north <^ Alby, and nearly 890 feel
above the sea. 1 shall revert to the local circumstances of these
mines as I proceed. At present it is sufficient to add, that my
experiments took place, in the first in August 1823, in the second

in all parts of this memoir.
With these explanations, I now proceed to the examination
of the experiments which have been made on the tempenUure <^
the air contained in mines.
1. Temperature of the Air in Mines. — The expetiments on
the temperature of the air of mines would be unobjectionable,
and we would have reason to suppose that they give the exact
temperature of the zone of rock in which they have been made,
had their circumstances been smilar to those of the caves of
the Observatory of Paris, that is to say, had they been made in
excavations of small extent, and especially of little height, ^tu-
ated in the ori^nal rock, defended by a suflicieat closure
from all foreign influence, such as the passage of workmen,
the access of water, the introduction of estemal ur, and ^ul up
fcH* a length of time sufficient to allow the original temperature of
the walls to be completely re-established. But none of these ob-
servations have been made in such favourable circumstances.
To appreoate the various kinds and degrees of inaccuracy to
#hich they have all been subjected, we shall first consider what
might take place in a mine, which we shall suppose of some ex-
tent, composed of several stages, free of titrations, and whidi has
been kept hermetically shut since the period at which it wasaban.
doned. The air in each stage would assume the temperature of
the surrounding rock. This air, upon the hypothecs which we
maintain of a heat increasing in the earth as the depth increases,
would continually circulate from the lower to the upper stages,
and vice versa, on account of the differences of specific gravity,
arising from the inequality of the heat which would take place at
each leveL These continual motions would be the more lively,
the wider and less uououb the subterraaeon canals were, and the
greater the number of thar communicaUons. In the opposite
case, the displacement of the ur would be produced slowly, eft-
pedally at the most remote extremities of each stage ; and it
would ha{^n, that, towards these extremities, the temperature
cS the lur would not differ much &om that of tbe surrounding
rock. In this case, and still m<H:« in the former, the temperature
of the air would never exactly represent in any point the tempera,
ture of the rock in contact with it, 3

If the identity of the temperaturee in question cannot occur In
such a mine as we have imaged, still less possible is it in com-
mon mines, to which the air has continual access, in which the
filtering waters incessantly act as a cause of variatioD, and where
the lights and workmen daily disengage large quantities of heat.
Let us examine the efiects which these three disturbing causes
produce upon the temperature of the air contained in mines.
Theextemal air, by continuallymixing' with the air contained in
a mine, acts in the ratio of the temperature which it brings to each
point, and of the mtiss which is introduced at this point in a given
time. Now, these two elements arecontiniuUy varying, and their
influence necessarily extends to the most distant excavations. I
estimate the velocity of the draught which lakes place by means
of the shaf^ that serve for ventilating mines, as being sometimes
four times and even six Umes as great when it is very cold as it is
in ordinu^ weather. The t^nperature of the air which enters
vaiies every day, every hour, or it may be said every moment.
Thb temperature is lowered more or less, from the effect of the
more or less abundant cvapwation which the air produces, by rea-
son of its dryness and original heat, in proportion as it circulates
along the humid surface of the excavBtions. At the same time
it u subjected to a very feeble cause of augmentati<Hi, which sel-
dom compensates the preceding, and which depends upon the in-
crearing influence of the atmospherical pressure, in proporticHi as
the air introduced penetrates into deeper cavities. This cause,
the ^ect of which has been exa^erated by some persms, could
oa\j augment the temperature of the introduced air, about five
or six tenths of a degree of Fahrenheit for a depth of 160 feet.
These data justify the proposition which precedes them. Fur-
ther, there results from them a curious fact, which it is of import-
aoce to establish ; namely, that the mean temperature of the nuug
<fakr which has been intro<luced into a mine in the course of a
year, is cntunly inferior to the mean temperature of the country
for the same year. According to various researches, which it
woidd occupy too much time to relate, I estimate the difference
as being from three to five d^rees Fahrenhnt, in most of the
mines of our dimates. Thus, not only does the introduction of
external air into a mine increase and dimtni^ incessantly, and in

a, more or less aendUe manner, the temperature of the ur eon-
ttuDed in the diffeimt perte of each stage, but it also tends ulti-
mately to lower the proper temperature of the whole excavaiioBs,
and this in a necessarily unequal manner in the difierent ports
utuated at the same leveL
The second disturbing cause, the filterii^ water, acts in a uni-
form manner, whether we OMidder its action in a very short, (»
in a very long peiiod. It also tends to diminish the temperature
of the air contained in the excavations in which it occurs.
It depends uprai the influence of the proper heat of the affluait
waters. Now, it will be seen hereafter, that these wata*s arrive
at the pmnt where they make thdr exit, with a temperature ac-
quired in more elevated Kones of rocks ; ccMisequently, the sur.
faces which they cov» in each excavatioo, communicate to the
air in contact a temperature lower than that cd the Burround-
ing rock.
The third disturlung cause, viz. the heat disengaged by the
workmen and the Hghts they use, exennses an influence the re-
vase of the preceding, an influence oftai poweifid, and which
has not yet been calculated, altbou^ it has served as a basis to
several peracms for denying the consequ^ices deduced bom ex-
perJmente made upon subterranean temperatures. It is essential
to value its eSects approximatively by numbers.
According to the intarsting researches at M. Despretz on a-
nimal heat, a middle wzed man disengages, m twenty-four hours,
by respiratifMi, a quantity of heat equal to that which would
raise 1 ounce ofwater to 805,709° Fahr«iheit,aDdthis heat is only
three-fourths of the total heat produced in the same period, by
the same incUvidual. Whence it follows, that the total beat
which is dis^gaged in an hour, is equivalent to what would
raise 4640 pounds of water (in round numbers), to 1° Fahreu-
heit. Making use of die proporUon (1,0000 : 2,669) which, ac-
ccadii^ to MM. de La Roche and Berard, expresses the difler-
ence (^ the specnfic heats of water and air, and setting out from
thespecific gravity which air poesesses at 54>° Fahr. of temperature,
it is definitively &uDd, that a miner disengages hourly a quan.

Dot without reason, tberrfore, that the jffeaence of worikmen and
lights has been alleged necessarily to exerdsea great influeooeup-
on the temperature of tbe air of miner. In geoenil this ioflunice
lends, during tbe greater part of the year, to counterbalance more
oc less completely the effect of causes which might keep tbe tempe-
rature of the air ctmtained in wa excavation, beneath the propw
temperature of the surrounding rock. Duringthe rest of the tjioe
it augutents tbe ^oess of Ute t^nperature of tbe air, over that id
the rock with which it is in contact at each stage. It acts, be-

of the wmrks, and tbe manner in which it oombines with tbe two

destly results from them a multitude of motirais, of pttrticuliir
Currents, oimI counter currents, almost always unperoeived by the
miner, which extend into all the parts of the excavations, and with-
out which, I DOW believe, that the ventilation of mines would be
very impwfect. I calculate, besides, that, in more than one im-
portant mine, when the external temperature is from 66° to 77°
Fahrenheit, the air which is introduced in thecourse of an hour
is not equivalent to the hundredth part of that which fills the
excavations.
To support the observations wUch I have just expressed, I
1^11 relate the result of some experimentH.
On the 9th November 18^, at seven in the roonung, when
I descended into the wcurking called the Havin, in the mine
of Canneaux, the external air six feet above the surface of
the ground was 66^.1 Fahrenheit. Five hours after, wh«i I re-
turned, it was 68°.8 Fahrenheit.
A single shaft which, not including the ptmardy was 48S
fbet deep, dewed the whole works. At the middle of the
entrance of this shaft, the air entering at the same hours as above
marked 2*.S Fahrenheit more than vithout. Thus it was al-
ready mixed with the warm air, which arrived in an insensible
manner from the bottom of the works.
The works were intended to prepare the extraction of two thick
beds of coal, nearly horiztmtal and parallel, and at an average
98 feet distant from one another. They consequently consisted
of two stages, formed each of wide galleries, crossed at right
angles, and traversed by a principal waggon way. These ex-
cavations, the digging of which had been pursued with constant
activity for seven years and a half, were then very nearly 558,450
cubic feet in extent. The ventilation was ^ected in the usuid
manner. From the surface of the section of the ventilating chim-
ney, and the velocity c^ the air which issued from it, I found
that the quantity of air introduced into the mine in an hour
was only 3705 cubic feel, that is to say, it was not equivalent
to the twelve thousandth part ol the mass contwned in the ex-
cavaQons.
Nineteen lamps and twenty-four workmen distributed in the
two stages, were constantly employed during sx days of the
week, and produced hourly a heat capable of nu^g 2°.99 Fah-

renheit the temperature of a mais of sir equal to that niiich fil-
led the whole of the galleries.
At the upper stage, the tempert^ure of the air taken in the
waggon-way, at an equal distance from the ndes, the ball of
the thermometer being suspended at a height of one foot fn»B
the rcx;k forming the roof, was as follows : 6d°.3 FahreiAdt
near the shaft ; 7S° Fahrenheit, a hundred and forty metres
farther on, that is to say, near a shaft forming a communica-
don for ventilation between the two stages; and 7S°.8 Fah-
reohdt at the extremity of the gallery, that is to say, at a dis-
tance of 790 feet fnxn the shaft. Froceetting in the same man-
ner, I found at the extremity of several galleries, whether paral-
lel or cross, a temperature varying from 78° to T^.S Fahren-
heiL The workmen, besides, had not entered the galleries for
some time ; the iur was perfectly stagnant, at least to appear-
ance ; and, accordiog to the commonly received ideas, th^ tem-
perature seemed calculated to ^ve that of the surrounding rock.
At the lower stage, proceeding in the same manner as above,
I found that the air at the bottom of die' principal waggon-
way, thi^ is to say 920 feet from the shaft, marked 74°.!
Fahrenheit. At the extremities of the other galleries into which
I entered, the temperature was only fnmi four to five tenths
lower than the above. At the roc^ of the canal ending in the
ventilatiDg chimney, the ascending air was 73°.6 Fahrenheit,
and consequently issued with a temperature m<n-e than 14°
Fahrenhat, above the external air.
Lastly, having determined in a direct manner, which I con-
uder a« accurate, and of which I shall give b description after-
wards, the proper and original temperature of the rock which
surrounded the bottom of the lower waggon-way, I found
it 62°.8. Thus I would have committed an error of nearly 11°
loo high, had I, in imitation of most observers, given the tem-
perature of the air of the unfrequented gall^ies of the lower
stage of the Bavin mine, as representing the real temperature
of the zone of rock, which is rituated in the same horizontal
plane.
The example which I have just adduced, is so striking that
I believe it useless to relate the numerous facts of the same na-
ture, which I have collected at Littry and Decise.

286 M. L. Cordier, Examination ofraxiU ExperimenU
In the course of my iavectigatioQs in the nuoes jiwt mention-
ed, as well as in several others to which I have extended my re-
sear^es within these six years, I determined another not less
iBteresting fact, namely that, at the sdme time, the tempenUure
ai the air is scarcely ever the same at the tower and upper puts
of a gallery, or any other work of the Eame kind. In a heiglit
of less than &ix feet, I sometimes found differences d Sf m even
7°. At . the Bavin mine, for exunple, in the whcde extent, end
at the extremities of the uofrequented galleries, the themome-
ter, placed at a distance (A S iniJies from the floor, marked i>om
16 to 2S tenths Fahraibnt less than near the roef. At the
extremity of the wi^^n-way of the lower stage, the difier-
enee was 3°.4. This remarkaUe diference prevailed o*er a
great extent, and as a considerable slope favoured the passage c£
the coded air toward the ventilating chimney, there cesuhed
at the floor of the gallery, a current which couUt be mi'-
dered sen^bla by means of a little smoke *, and wfaioh su^
piied the defect <A communication between the estremities of
the twei stages. The warm ^r which oeeu^ned the upper pan
of the gallery had a motiori in the contrary direetion^ dod flowed
to undergo the effect of cooling which die fresdiLy expneA sut-
facea at the extremity of the perforation operated upon it. The
sane dfects took plaee at the upper stage, which made the
workmen entertain the apparently ^urd <^nion, that the Mr
came from the bottom of the works.
The last mentioned experiments axe aiio those which have
contributed the most to make me discover that the inftneiace of
die causes which occauon the temperature c^ the air in mines to
vapy incessantly, assuredly extends to the bottom of the msat
distant wcwks. The consequence^ which are to be deduced from

From all that ve have hitherto related, it may be concluded
widi certiuDty, that none of the observations collected on the
temperature of the mr in mines, exactly represent the proper tem-
perature of the zone of rock at whose level it was made. Sup-
po^ng that, by a concurrence of extremely improbable compen-
sationa, some of these observationB having taken place at the n>o-
m^t wh^ there existed an identity of temperature, nothing
cotildapprizeusof so fortuitous an accuracy. None of them, there-
fore, is capable of being compared with the mean temperature of
the country in which it has been made. Those which have been
obtained at different levels in the same mine, on the same day,
and at not many minutes distance, are not more capable of being
compared with one wwtWr, although in general tbey are more
useful to be consulted than alltheothers. No other use, therdbre,
can be made of thk mas* of observations than as mere documeatt.
It must be confessed, that, even in this view, most of them
leave a cfmsideFable degree of uncertainty, for, in publishing them,
th^ authms have only made known a small part of the detaila
which would have been necessary fot the establishment of th«r
resl value. There is but a small number whidi, after being sub-
mitted to the soutiny resulting from the principles exposed above,
oonld be regarded as givii^ a temperature either uesrly the same,
or certainly infericv to that of the level to whidi they refor. Tb«
ohservatifHM of this kind are those which have been made' dunag
cold weather, or in circumstanoas entirdy exceptionable^ for exam-
ple, in excavatioDsof small extent, although deep, dry, and long
deserted. Now, these obses'vatkxis all proceeded intheEamedtrec
Uon, and although they can only be considered as approxima-
tive, yet they positively indicate the existence of a certun in-'
crease of heat proportional to the depths.
We connder it useless to mention these latter observations ia
detiul, because it will be easy to dininguisb them in the midst
of all the others of the sune kind that have been published, and
becauK we shall presenUy discover the existenceof better proofs.
These conclusions certainly aoe not without interest; but they
988 M. L. Cordier, Examination of recent Experiments
are far fnna being so Batisfactory as there was reason to expect
from the number of experiments that have been made, and the
perseverance which several observers have applied to them. We .
are iudemniHed to a certain decree by the exception which is to
be made in favour of the experiments of the same kind, but
sedentary, which have been carried on for so long a time in the
old quarries called the Caves of the Observatory of Paris. These
are conclurave, and are capable of yi^ding a numerical and ab-
solute result. Their accuracy affords a compensation for the
small depth which they embrace. They incontestibly announce
a pretty rapid increase of the subterranean heat. At (he level
of 92 feet, the mean temperature of a thennometer immersed
in a recipient filled with sand, and supported by a pillar, keeps
at 1°^ beneath the mean external temperature. In the course
of a year, the variations of the thermometer do not exceed ,*,d of
a centigrade de^^e.
Such is, in fine, the merit of the experiments that have been
made upon the temperature of the air in the cavities, by means of
which we can penetrate into the bowels of the earth. We shall
now examine whedier the results that have been obtained by
proceeding in a different manner, and especially by consulting the
temperature of the waters which exist in mines, present more
numerous or more certain resources, with reference to the object
which we have in view.
2. Temperature of the Water in Mines. — Water presents
itself in various ways in mines. Here it issues from the rock
under the form of filtrations, more or less copious ; there it tra-
verses the bottom of the excBvatJMis in small brooks. Elsewhoe
it is stagnant, and constitutes pods or true subterranean lakes.
Not viewing the observations which have been made on the
vater thus contained in mines, otherwise than as merely forming
a mass of approximative documents, we may yet, without he«-
tatjon, conclude from them that there exists a notable increase
in the subterranean heat. In fact, the experiments were made
at Afferent seasons, and the results are all higher than the mean
temperature of the country where they were performed. The
differences increase rapidly as the depth increases. Whatever
inSuence may be attributed to the summer rains, with reference
to the temperature of springs and filtrations, to the air during
warm weather, or to the lights and the presence of the work-
on Subterranean Temperatures. S89
men, wiUi re^>ect to the running or stagmmt waters, there is yet
remaining a great number of obaervationB, whose testimony can-
not be refused. The consequence above stated appears there-
fore inconteslible ; but it is all that con be drawn from the expe-
riments. . Thus, as we shall presently see, the numbers which
they furnish cannot be regarded as sufSdently accurate to en-
able us to deduce from them, in a certain and absolute muiner,
the law of the increase of temperature in depth ; some of them
would make it too high, and others too low.
As it is, however, a great step gained to be assured that there
is an increase, and that this increase is probably rapid, it is es-
sentrnl to take in here the result of an experiment of Mr ,W.
Fox's, which is much more important than it seems at first sight,
and which would have had much more interest, had not the au-
thor omitted to relate sevaral circumstances which he had done
well to have mode known.
The waters which issue from most of the numerous tin and
ct^per mines of Cornwall, are led by means of various branch-
ings into a great adit, which conducts them above the valley of
Carnoo, and which, at its termination, pours forth 1400 cubic
feet of water pec minute, amounting to about 60,000 tons in the
day. In one of the branches leading to the great adit, the wa-
ter of six mines, from 900 to 960 feet deep, Mr Fox, at half a
mile-from its mouth, found the water at 7<t° 4' Fahr. In a second
brancli, leading off the waUr of ten mines, having a mean depth
of frdm 660 to 7S0 feet, the temperature was 66° 6' Fahr. at a
third of a mile. In a third branch, which drains sevenmines,
whose mean depth is frmn 600 to 660 feet, the water marked
64° 9'- Lastly, the temperature of the united streams, taken at
the mouth of the great canal or adit, was found to be 69° 3'
which is 10° 7' cent above the mean temperature of the coun^
try. In the second place, it may easily be proved, by meaiis
«^ the data which we have already enumerated, that it is indepen-
dent of the influence which might, in other cases, be attiibu-
ted to tiie hghts and the presence of the workmen. In fact, if
H be admitted that the working of the mine requires the con-
stant employment of 3000 workmen, and 3000 lamps, burning
each one-half ounce of oil in the hour, it will be found, that, in
one hour, the heat produced by the ligbts and workmen will

ing the law wfaic^ the increase of the subtenanean temperature

There is an infinity of dsmcea- against the water of filtraUona

die Tock from which they issue. In fact, the original heat tS
the nciD.wata' which paietratcs inlo the soil continually varies,
bdng sometimes superior and sometimes inferior to the mean
temperature of the country. These <^%rences are often very
great during a whole season. M<H-eover, the ori^nal heat is
subjected to many modificatioiis, which depend i^ioa the depth
to which the waters descend, tbe number and length of the ca-
nals, the slowness <A the cinmlation, the length of time that it
hasbeenestablidted, and the number and extmt <^ the masses of
water traversed, if there be any sudi in the lines of pouage.
These elemoits are very complicated, and it would be neceasny
to possess their ffl:pression, in order to ^^jweciate the merit of their

not have. AU that we aie permitted to conclude is, thart most of
the experinKDts are fwobebty very af^nozimetive, and that tbey

might be posnUe that the water of a spring, or filtration is a

Getteral Description.
X HE district of Darwar, in the southern Mahratta country, is
of an irr^ular triangular ^ape ; the apex erf the triangle being
towards the south, in north latitude 14° 9ff, and its base to-
wai'ds the north, on an average, in 16° ^. Its most westerly
point, towards the Goa territory, and which forms one of the
angles at the base, is about ^¥ 5' east longitude ; and its most
easterly point, which is the remaining angle, is in east longitude
76° S9:. It is bounded on the north by the Kolapore country,
and the river Kistnah ; on the east by the Hydrabad country,
and the Honourable Company's district of Bellary ; on the
eouth by Mysore ; and on the west by Soonda, (a district of
Canara), and by the Western Gauts, which divide it from the
Goa territories. Within these boundaries, besides the Briti^
possessions, are many separate tracts^ belonging to independent
Ja^eerdars, and tributary chieftains of different denominations ;
but 30 subdivided and varied in their outline, that it would be
nearly impossible, and of little use, to give a description of
them.
The following observations are not exclusively confined to the
Darwar district ; but sometimes extend to that of Canara, and
to the Portuguese territory of Goa, and thus occasionally em-
brace the whole tract of country from the Tumboodra to the
coast. /
The Darwar district is very generally known in India by the
name of the Southern Mahratta Dooab ; which name it has re-
ceived, from the circumstance of its extending between the rivers
' Kistnah and Tumboodra. But this term properly includes the
whole tract of country eastward, to the junction of these two
rivers, and thus embraces a considerable portion of the Nizam's
dominions. When this term occurs, therefore, in the course of

the followiog observations, it is to be understood in the above
extended sense.
The Gauts above 6oa, and which form part of the western
boundary of the district, have an elevation of S600 or S600
feet; above the level of the sea, whence the country gradually
slopes to the Tumboodra, which is about IfiOO feet above the
level of the sea*. In this part of India, there is nothing Hki"
mountainous scenery, except immediately under the western face
of the Gauts ; for as soon as you attain their summits in pro-
ceeding eastward, you are on the inclined plun which shelves to
the eastern coast ; and the general declination of which, is only
interrupted' by gentle hills, which seldom attain a height of above
t#o or three hundred feet.
Immediately to the east of the Gauts, the country continues
hiDy for about thirty or forty miles ; the hills being covered with
wood, which becomes gradually thinner, and more stunted, to-
wards the east. Beyond this hilly tract, as far as the eastern
frontier of the district, the country consists of exten»ve plains,
intersected in different places by long narrow ranges of sandstone
hills, with even summits.
This particular configuration of the country, gives rise to
striking peculiarities in its climate ; and, consequently, in the
vegetable and animal productions of its different parts. This
circumstance renders it susceptible of a very natural division into
three distincf parts ; viz. into the western or hilly part, the
plains which occupy all the central and eastern parts of the dis-
trict, and the ranges of sandstone hills, which intersect these
^ains.
The summits and western face of the Gauts afford, in many
places, the most savage, and, at the same time, beautiful scenery.
A boundless forest of gigantic trees, with the utmost variety of
foliage, covers the highest hills, and penetrates into the deepest re-
cesses of the valleys. In some places, enormous masses of black
rock, which appear to have been rent from the neighbouring
hills, rise high over the tops of the woods, and form a fine con-
trrat to the rich green of the surrounding foliage. Wherever

theforest opens a little, so as toadmitof the grotrth of humbler
plants, the ground is covered with the most luxuiiant grasses,
and flowers of the richest hues. The atiliness of this wilderness
is only inierrupted by the sleepy sound of a mountiuQ stream,
or occasionally by the harsh cry of some solitary birds, or the
loud hollow roioe of u mcMikey. Animals are seldom met with .;
and often an your journey, nothing is to be seen for hours but
an endless luxuriant vegetatiof).
Some very beautiful waterfalls are met with in the western
Gauts, but many of these are completely dried up in the hot
season. There are very fine falls in the Gauts above Hoooor,
which^ for sublimity and magnitude, will probably yield to few
in the world. They have hitherto been little known even to
£ucopeans in India; and it; is, I believe, only within the last
ten or twelve years that they have received a name. They are
situated on the river Shervutty, about fifteen miles up the Gauts,
from the town of Gar^pa. They are now known to Europeans by
the name <^ the Falls of Garsipa. I visited them in the month
(^ October 18S5. •
The country in the neighbourhood of the falls is extremely
beautiful, combining the majestic appearance of a tro^cal forest
with the softer characters of an English park. Hill and dale
are covered with a soft green, which is finely contrasted with a
border of dark forest, with numerous clumps of majestic trees,
and thickets of accacias, the carunda, and other flowering
shrubs.
Upon approaching the Falls, you emcfge from a thick wood,
and come suddenly upon the river, ghding gently among con-
fused masses of rock. A few steps more, over huge blocks of
granite, bring you to the brink of a fearful chasm, ro(^y, bare,
and black; down into which you look to the depth of a thou-
sand feet ! Over its sides rush the different branches of the
river, the largest stretching in one huge curling pillar of white
foam, without interruption to the bottom. The waters are, at
the bottom, by the force of their fall, projected far out in
strught Unes ; and at some distance below the falls, form a thjn
cloud of white vapour, which rises high above the surrounding
forest. The sides of the chasm are formed by slanting strata of
rock, the r^ularity of which forms a striking contrast to th?

disorder of the tumultuous waters, the broken detached masses
of stone, and the soft tint of the crowning woods.
The eflect of all these objects ruling at once upon the eight,
is awfully sublime. The spectator is genorally ibtced to retire
After the first view <^ them, in order gradually to familiarize
himself with their features ; for the feeling which he experi-
ences upon th^r sudden coDtempktioD, amounts almost to pmn.
After their lirst impression has somewhat subsided, and he has
beccHUe accustomed to their view, he can then lesurely aoalyze
their parts, and become acquainted with their details.
The chasm is somewhat of an elhptical form. At its narrow-
est and deepest part is the prindpal fall ; and over its fddea .
smaller bnuiches of the river and little rills are predfutated,
anA are almost all disnpated in spray before they reach the
bottom. The prindpal branch of the river is much contracted
in breadth, before it reaches the brink of the predpiee, where it
pcobaUy does not exceed fifty or axty feet, but it contains a
TCTy lai^ body of water.
The Falls can only be seen fA>m above, for the predpices, on
both sides of the river, afford no path to admit of a descent.
Some g^tlemen have attempted to reach the bottom by haviag
themselves lowered by rc^s ; but no one, to my kiiowIe%e,
has hitherto succeeded. A view of the Falls from below would,
I am convinced, exceed in grandeur every tlung of the kind m
the world. The spectator can very eaaly, and with great safe-
ty, look down into the chasm to its very bottom. Some large
plates of gneiss project, in an inclined position, from its edge ;
so that by laying himadf flat upon one of these, he can stret^
his bead conaideraUy beyond the brink of the precipice.
No accui'ate measurement has yet been made of the height
of these Falls. Some who have seen them declare, that thdr
haght reaches at least 1100 feet ; others, that it does not readi
1000. I preparsd a rope 900 feet long, attached a stone to <Me
end of it, and let it slip over the edge v/t a rock, which projects
several feet beyond the side of the predfMce. When 500 feet
of n^ had been let out, the stone was fordbly drawn towards
the prindpal cascade, which soon involved it among its watov,
and snapped the rope. The stone at this time appeared to be
about 300 feet from a small ledge of rock, which might be be-

tween SOO and 300 feet from the bottom. It is not improbable,
therefore, that the height of the fall is Dot much short of 1000
feet.
We shall now return to the description of the Darwar diatriet.
It has been stated above, that it may be divided into three parts,
viz. the western or hilly part :, the great pluns in the central and
eastern parts of the district ; and the sandsttxie hills which inter-
sect these plains.
The boundary between the plains and hilly tract is very irr&-
gular. Proceeding from the east, a few insulated, low ranges
ore first met with, having a general direction of north-west and
floutb-east. The bills continue in parallel ranges with the some
direction, for many miles to the . westward. But when within
nx or eight miles of the summit of the Gauts, the scenery as-
sumes a more irregular character, the hills being heaped more
together, with steeper sides, and more irregular forms. The
rugged and wild features of mount^nous scenery are nowhere
met with ; for the hills are generally somewhat rounded, are
softened with a rich vc^tation, an& resemble, Jn their general
character, the hills of Cumberland, or those between Geneva
and Lyons,
The second divi^on, or the plains in the central and eastern
parts of the district, are precisely similar to the exten^ve plains
■ of cotton ground met with in every part of India. They are al-
most entirely in a state of cultivation. During the rainy and
fxAA seasons they are covered with luxuriant crops. The regu-
larity in which these are planted ; the great variety of colours
produced by the numerous kinds of grains, pulses, oil and cot-
ton plants, and the great extent over which they are spread, af-
ford an appearance of riches and prosperity. In the hot months
the scene is entirely changed ; you then look around on an arid
plain, whose deep black soil is every where intersected by wide
fissures. Not a patch of verdure, not a tree or shrub, is to be
seen. Clouds of dust are swept along by the parching wind, or
huge pillars of ii, raised up by whirlwinds to the height of a hun-
dred feet, are seen stalking across the plain; or (if the atmo-
sphere be calm) fixed for a length of time to one spot. This ,
cheerless view is only terminated at a distance by a line of saiid-
stone hUls, whose even summits give them the appearance of a

not even the hum of an insect being heard.
The sandstone tract occupies all the northern parts of the dis-
trict. It commences to the east of Gudjuuderghur ; whence it
extends north to the Kistnah. Its southern boundary runs frmn
Gudjuoderghur through Jullesl and Eonoor to Pursghur ;
whence this tract extends, with some interruptions, dorth to the
Kistnah, and north-west to Gokauk, Padahopore, and into d>e
Kolapore country. Within this tract, however, are many ex-
tenfuve plains of cottoii ground. The sandstone hills are inva-
riabty in long ranges, the general direction of which appears to
be north-west and.sonth-east. Many of tlie valleys betWeai
these ranges possess a soil of pure sand, the debris of the neigh-
bouring hills. The hills are generally bare; and where they
possess a slight covering of stnl, produce only a few stunted
shrubs, conusting jHindpally of cacti, mimosas^ and the cassia
auriculata.
Anotfaer range of hills of much less estent than the sandstone
bills, and which could not be included in any of the above di-
vin<His, deserves to be noticed in the physical get^raphy of the
district.. It is called the Kupput-Grood- Range. It consiBts of
^MDte and schists ; and extends from near Guduk, id a south-
east direction, as far as the Tumboodra. Were it not for this
rai^ of hills, the cotton ground plains would extmd uninter-
rufrtedly from the "aouthem extremity of the district to Gudjun-
derj^ur and Konoor.
Five rivers water this district, viz. the Kistnah, the Tumboo-
dra, the Gutpurba, the Mulpurbah, and the Wurdah. The
two first are by far the most condderable, and form the northern
And southern boundaries of the district. The three others are
reduced to comparatively small streams in the hot season. They
-aU take their rise in the Western Gauts. Besides these, there
are num^us streams, or nullahs, as they are called, the most
considerable of which is the Beyny nullah, which has its source
among the hills in the neighbourhood of Miscrecottah, flows
northward through the black plains, and falls into the Mulpur-
ba. Most of these nullahs arc dried up in the hot season.
These rivers and nullahs, except in the western parts, ore

waf through the deep cotton groiind, which, in the dry aeaflon,
fcurms precipitoua banks, deep, black, and bare ; and thus, in
nurny [Jaees, the river has more the appearance of a great arti-

Meteorology ^the Southern Mahratta CottfUry.
The most oppomte ciimates are met with "in diffiomt parts of
the southent Mahratta country ; for the western parts, towaids
the Gauts, may be redumed among the wettest ports of the In-
dian peninsula ; and the eastern among the driest. The aver-
age quantity of rain in the latter may be reckoned st fium 90
to 26 inches ; in the former, a lai^;er quantity than this oft«i
falls within one month *. The dimate becomes gradually drier
as we ^wooeed eastward, itam the chain of the western Gauts ;
and as this cfaun runs N.NW. and S.SE. we have consequently
a drier chmate in the northern parts of di£ district, than in the
southern, en thftsame meridian. Thus, at Soondah, the di-
mate is rainy and cool ; at Gi^auk, on the other hood, whidi
is in the same longitude, it is dry md hot
A considerable quanti^ of ram falls as far eastward as the
cmintry omtinues hilly ; but beyond this the supply is scanty
and precarious. In August 1824, a good deal of ,rain fell at
]i>arwar ; while, at the same time, not a dn^ bad fallen fifteen
miles to the east, and the wells there were nearly dried up.
For three weeks in July and August this year (18S7), neariy
ii^essant rain fell at Darwar, and dining die same ^me not a
Amp fell in the eastern parts of the district.
The difference in the balnts and mode of life of the inhaln-
tants of the western and eastern parts of the district, abundantly
testifies bow very oppodte are tbdr respective climates. In
many fdaces, the former are often for weeks durii^ the mon-

soon oonfinad to their own Tillages or huts, not only by the se.
verity of the raios, but in many instances by the aUipptge of
iheir oommunicatioD by the svollen nullahs. During tlds dreary
period, (in anticipation of which a stock of prorifflODS is. always
laid in as a ship is supplied for a voyage), the inhalntants git rou^
a fire in the ceiitre of th^r miserable dwellings, which are thns
constantly filled with smoke. When they do venture out in
this weather, they wr^i themselves in a cumly *, and over this
they place " a sort of thatched case or shell, made of the leaves
of the jar f , or some other of the paltn tribe. It is broad over
the whole back and shoulders, narrowing to a peak immediate-
ly over the bead, and coming down the front over the face, just
sp far as is necessary to give it a firm hold, with a slc^ suffi-
dent to carry the water that falls on it clear of the body ^.^
In the eastern parts, it is yery different The rain is sel-
dom so severe as to prevent the inhabitants from going out for
four and twenty hours at one time: — and ther^ precautions
against heat, not agunst cold, are necessary.
The villages in the western parts consist of thatched huts,
whose steep sloping roofs nearly reach tbe ground, the walls
bong only a few feet hig^, that they may he effectually pt<t-
tected from the tm. Every spot is covered with vegetation.
H^ges and trees covered with twining plants line the roads,
and the thatched roofs are often concealed by creepers, general-
ly cucumbers, pumpkins, &c.
The villages in the eastern parts present a curious contrast to
the above. Generally not^ spot of green, for many months in
the year, relieves the horrid glare. All is parched and brown.
No protection bdng required against heavy rain, the houses ace
built entirely of clay, which one heavy shower, such as the west^
em inhabitants constantly experience, would completely level to
the groimd. The walls of tbe houses are formed of- sun-baked
clay, and are from eight to ten feet high. Upon these is sup-
ported a terrace roof, composed of branches of trees or bamboos,
covered with clay. Nothing can be conceived more ugly than
these villages. On every «de square masses of dry clay, give

In these places, wood being found in too small quantity to
serve as fuel, oow-dung is used for this purpose; vfaicb being
made into small cakes, b thus plastered on tfae .walls of the
houses to dry in the sun. When dry, it is collected into stacks,
like peat-stadcB in a Scotch village.
Darwar, which is situated on the eastern edge of the hilly
tract, enjoys a tolerably cool and agreeable climate. The only
time at which the heat is very oppresnve is in March, Ajnil,
and part of May ; and even then a cool refreshing westerly
breeze sets in every afternoon, and continues during the whole
night. The luxury of this breeze is duly appreciated by those
who come either from the interior, or from the eastern or west-
em coast, where the nights, during the hot season, are close and
of^resive, preventing sound sleep from refreshing the languid
frame, overcome by the heat of the day. This cool breeze is
felt but a very shmt way to the east of Darwar, for it soon be-
comes heated, by passing over the arid pl^ns of that part of the
country,.
Speaking generally, it may be said, that, at Darwar, as in
other parts of India, the wind blows' during six months, viz.
from the middle of April to the middle of October, from the
Bouth-west, and during the remtuning months from the north-
east. But it has been already mentioned, that, during the hot
months, a cool wind blows all night from the west ; and it must
be added, that, for several weeks, at both equinoxes, the wind
is variable.
Heavy thunder-showers fall at Darwar in April and May.
The weather then continues cloudy ; and the steady rain of the
monsoon generally begins in June or the banning of July. It
is a curious circumstance, that the first heavy showers that fall
do not come from the west, but are accompanied by the follow-
ing phenomena. During the day the wind blows steadily from
the south-west Between three and five in the afbrtHwo, black
clouds are seen accumulating in the east. Cloud rises over
cloud, until the whde eastern sky is covered with one dense
black mass, which, now pierced every where by forked light-
jiing, and accompanied by constant peals of thunder, slowly ap.
proaches agunst the western breeze. When it has approached '
t^the Southern Mahralta Country. ^1
very near, the wind suddenly changes, blows strongly rrom the
east, and brings along with it heavy battmng rain, and some-
times large hail. The wind changes frequently, blowing from
all quarters of the compass, until at length it again beonnes
steady from the west, and the tempest ceases. This is repeated
every day for some days, after which the wind (xxitinues to blow
constantly from the west for five or six nuHiths. Storms also
occur at the autumnal equinox, but not so regularly nor so
violently as those just described.
Although there is a good deal of runy weather at Darwar,
yet there are seldom such deluges of nun as frequently occur on
the coasts ; and the total annual quantity of rain is certainly
less than that which falls either on the western coast or on the
Gauts.
It is a curious circumstance, that, while a cool breeze blows
during the nights of the hot months in the southern Mahratta
country, there is often at the same time a most perfect.calm on
the western coast ; proving. that this is not a sea-breeze, as. sup-
posed by many. It is probably owing to the peculiar surface of
the country, and produced in the following manner. The Gauts
and western parts of the country being covered with wood; and
nutre plentifully supplied with moisture than the interior, must
consequently be always cooler; but more especially at night,
for the arid plains retain the heat of the day longer than the
moist woods. The hotwr of the interior, therefore, will ascend,
and be replaced by the cool air from the western jungles, and.
thus g^ve rise to a refreshing breeze, which will continue all
night, and as long as it is not counteracted by the prevalent
north-east wind, which, being always more powerful during the^
heat of the day, then gains the ascendancy. Now, as the west-
ern parts of the country are 2500 feet above the western coast,
the wind which blows over them does not ascend from the coast
below ; for it has been already stated that the atmosphere on the
coast continues calm: it must therefore be supplied from the,
same altitude ; and we may accordingly conclude, that a mass
of ^r above 2000 feet in height rests undisturbed on the coast,
while that immediately above it, viz. on a level with the summit,
of the Gauts, is in rapid motion towards the interior.
The following remarkable and interesting appearance^ which

SOS Mr Christie ott tlie Meteoro^f, Geohgy, S[c.
I observed at Goa on the 6th of October last year, ^w, in a
strikuig manner, what a great influence the Gauts have on the
meteorolo^cal phenomena of this part of India, and also con-
firm the above observations regarding the western In'eezes of the
aoudiem Mafaratta country. I>arge masses of clouds, with
Ughtnk^ and thunder, were observed oa the Gauts about mid-
day. The clouds gradually proceeded westward, but at a very
great altitude ; and, in the evening, they completely concealed
the blue sky, stretching far to the west over the sea. The air
hejow continued close and oppressive, and thunder waa heard,
h^;h over our head, among the clouds that had proceeded from
the Gauts. Thus the air, resting on the low country, continu-
ed uocfisturbed, while great hygrometric and electric changes
occurred in the atmosphere, only on a level with the summit of
t^ Gants.
Fogs in the morning are very common at Darwar, and often
present a very remarkable appearance. They invariably pro-
ceed ftom the west, and, about sun-rise, are seen rolling, in dense
tmsaes, over the hills. They sometimes appear black, at other
times perfectly white, according to the spectator's iutuation in
respect to the light They are generally not v^ high, and
vary much in their form and extent ; sometimes covering a great
tract <rf country, at other times being very partial, and stretch-
ing oat, as it were, into long bands. When riding out in the
mwiung, I have frequently observed a thick mass of log on
eech nde of me, while the intermediate space was clear; one of
the masses having a black, the other a white ct^ur, arising
from their different situaticxi in regard to the rising sun. These
fogs nevOT last longer than a few hours.
Having been ordered, by the Bombay government, to keep a
register of the weather at Darwar, the following was commenced
in January 18S7. There ought also to have been a register of
die barometo- xoA hygrometer, but the Ibrmer of these instru-
ments was broken in its carriage to Darwar, and the latter
could not be fancured in India.
The thranometer was kept in a broad open virandah, at a
distance ftom any wall, and, at the same time, completely in
the shade. The spring-water, the temperature of which was
taken, was from a well about ^xty feet deep.

In the following table the mean of two obserrations, made at
10 A. H. and 10 p. u., is gneHf aa probably aficaxliog a very
near approximatioo to the true mean of the twenty-four hours.
In order to ascertain how far this rule held good at Darwar, I
observed the thermometer every two honrs, day and night, du-
ring two Buccessive days in Februaiy and two in March 18S7|
and found that the mean of all these observations was within
jg^ths of a degree of the two observatJons made at 10^ a. h. and
10 p. M.
It will be seen by the following table, that the mean tempe-
rature c^ the first ten months of 1827 was 75.31S, and of qtring-
water 75.635. This will probably be a little too high for the
mean of the whole year; for November and December are
among the coolest of the twelve months : 75 therefore is, per-
haps, a very near approximation to the true mean temperature
of Darwar. The total quantity of rain which fell, from the
otunmencement of the runs in Ajnil up to November, was 26,'^
inches. The rain which fell in January, was quite unusual,
aiul,^ indeed, such a (ircumstance was lot remembered by the
oldest inhabitant to have ever happened before. A few showers
sometimes fall in November and December, but never at^ heavy
rains. The supply of rain at Darwar, in 1827, was oonsider-
ably less than usual.
Belgium, which is the military head quartwa of the divisioa,
has a much cooler climate, and a much lai^^ supply of rain
than Darwar, omng to iu vidnity to the Crauts.
The mean temperature of Darwar is probably about t^i de-
grees below that of Madras.

freezing point. At Upsala it is 4S° ; at Christiana 43* S* ; at
Paris 5S° 4'. The sun at the North Cape is never visible from
the midtUe of November until the end of January ; but, on the
other hand, it never dnks below the horizon, or is out of sight,
from the middle of May to the end of July.
The snow r^on at the North Cape is S400 feet. At Lat.
70°, the shooting forth of the leaves takes place six or seven
weeks later than at Upsala, and three weeks later than at Tor-

The supposed recent Origin of America refitted.
A VARY ingenious naturalist, Mr Smith Barton, has said,
with moch justice, " I can only connder as puerile, ee\A in no
way proved by natural evidence, the suppontion that a great
part of America has emerged ttom the bosom of the wa-
ters at a later period than the other continents *." May I be
permitted lo quote a passage from a memdr whidi I composed,
on the Native Tribes of America f . " Justly celebrated wri-
ters have often repeated, that America is, in every sense of the
word, a New Continent. That richness of v^;etation, that mass .
of immense rivers, those great volcanoes, always in actitHi, an-
nounce, say they, that the earth, incessantly trembling and not
entirely dry, is iess removed from the original chaotic state than
in the c^d world. Long before my voyage, audi ideas iqipeared
to me as unphilosc^ical as o{q)oaed to the generally known
laws of phyncB. These images of youth and disorder, as well
as of dryness and pn^pvssive loss <^ vigour in the Earth, as it
grows old, could only orig^ate with those who amuse them-
selves with seeking out contrasts between the two hemispheres,

ty reign in the New Continent, while in the Old, the discords vS.
the nstiong drive men to seek for rest in the boaom of nature.
Peihaps a time will come when one part of the world will take
the place of the other in this sdngular contrast between |^;iacal
and moral enei^. Volcanoes rest fac ages, before they are
ifiain lighted up. The opinion that, in the older regitxis, th«%

on a play of our imagination. One side of our planet can never
be older than the oth». The idands produced by vtJcanoes,
«uoh as the Aaores, or gradually formed by moll usca, like many
if^ds of the Pacific Ocean, are in general more recent than the
panite masses of the coitral chain of Europe. A country i£
small extent, like Boh^nia, and several valleys of the mocm,
circularly inclosed by mouDtainB, may long remain covered with
water, in consequence of partial inundations, and form a lake.

JceoufU of a Deposite t^ Fossil Plants, discovered *n ike Coal
Formation of the Third Secondary Litaetkme, near Scar-
borough. With a Plate. By Petbk Hubrav, M. D. Com-
municated by the Autbco' *.
aN interesting geological discovery has lately been made ne^
Scarborough, io Yorkshire, in Gristhorpe Bay, of a large depo-
site (^fossil plants of the coal fonnation, presenting maoy varie-
ties hitherto undescribed.
They occur in the strata called Coaly Grit by Mr William
Smith, a pseudo coal-field below the corn-brash, but far shove
the coal measures of any moment, being Buperior even to the
Oxford clay, mart-stone and liaa. The thin seams of coal wludi
accompany these plants are the highest in this vicinity, overtop-
ping the Bath or inferior oolite ; which agwii is above the other
veins of bad coal which rise over the lias beds to the north, and
contun similar v^;etable remans, along witJi a singular mindi-
' naceous stem, called by Mr Merchison Oncylogonattim carbona-
rium.
The Gristhorpe petrifactions appear in a fis^e indurated day,
passing into a soft grit, and occasionally ^temating with clay
iron-stone, which is replete with nodules, intersected with veins
of calcareous !^>ar. and generally io the'centre contahitng s(»ne
vegetable impresraons, for the most part varying irom those in
the day ; and, on account of the hardness of the stone itself, of
^■eater sharpness and preservation. The plants lie layer above
layer horizontally, and those of the same Bpedes (with some ex<
ceptions) occurring together, asif the localities of each had been
extremely limited, and apparently as they had been swept down
by a great and sudden torrent of water, many being laid, the
one crossing the other ; or bent partly underneath one branch,
and then thrown over another, and some of the leaflets, as it
were, squeezed together : Some very small and young ; others
large ; others again even in fructification ; and several of the spe-
dmens of considerable magnitude and b«iuty, and in admirable
preservation.

Slit Dr Murray oh a Deponte of FottU I^attts,
Tbe plants are prindpaDy ferns, and are decidedly differept
fitHn those of our other coal-fields ; and most nearly reaembling
the spedmens from Bomholm in the Baltic, but congeneric with
many now existing in tn^ical regions.
Addiliooal spedes are detected almost daily ; and those al-
ready distinguished must exceed fifty. This prodi^us varie.
ty of fossil Alices, compared with those now vegetating in our
climate, must strike the most casual observer. Here, in one
narrow spot, not exceeding two or three acres in extent, we
have already found fifty species ; and, in a smilar, but mbk-
vibai lower formation, within ten miles distance, at Clou^tcm,
several other kinds, totally distinct, ofiering a number exceed-
ing that of those now living in the whole island of Great Bri-
tain. So that these northern r^ons must, in those early ages,
have presented as numerous and divernfied a display of ferns,
many most specious and luxuriant, as the wilds of Southero
Africa now do of the heaths ; although we must not presume to
ctxnpore the dark unvarying hue of fern clad wastes, with the
splendour and endless tints of the heathy plains of the Cape.
The interesting d^wnte at Gristhorpe Bay may be omudered
as a vast herbarium, of whidi the leaves opening to the readiest
ofaaervation, offer every bcility and pleasure in the examinatioti;
and not, as is the case with the generality of coal plants, sur-
rounded with dirt, and darkness, and perils, imbedded in the
FQofs atid sides of mines ; and they resemble so many fine draw-
ings in Indian ink, or the shadows of delicate foliage by moon-
light cast upon a smooth and white ground or wall.
Tbe v^table nature of these curious imfvesuons is remark-
ably shewn by the scarcely fossilized state of one of tbe varie-
ties, apparently a fern allied to the genus Isoetes, which, when
detached from the imbedding stony mass, still retains elasticity
and flexiUlity, and burns like a piece of charred wood. Others
yet preserve, even in their clay bed, much of their original co-
lour, a dull red resembling that of some fuci ; and porticns of
such leafiets may be peeled away, — are perfectly flexible and com-
bustible, — and are actually semi-transparent and striated, and
afford most pleaung and curious objects for a microscope. They
are, however, so completely carbonized, as not to yield either
tannin or re^nous matter, in the experimenu which I have in-
stituted. ^ ,,j„
diacmxred in Gristhorpe Bay, Yorkshire. 313
Several of these ferns apparently range under well known
genera ; and one espetnalty is characterized as a polypodium, by
ks tines of round seeds along the back of the leaf, parallel to
the central vein or mid rib ; and another, as an equisetun), by
the ^ike of cr3rptogamous flowers, and verticillatc leaves.
Olhers, again, deficient in fructification, can only be guesaed
at by the general habit ; and of such, we seem to detect exam-
ples of the genera of Asplenium, Scolopen'dnum, Isoetes, and
more abundantly of the Folypodium, comprising the Aspidium,
Cyathea and true Folypodium. The fact is, the genera of ferns
axe sufficiently obscure and difficult to arrange, even in a recent
state ; but, when fossilized, nearly impossible sadsfactorily so to
do, as species in a state of fructification are rarely to be met
with, and even then the involucre, upon which so much de?
pends, is, and must be, indistinguishable. Some specimens i^
pearof species now unknovm in Eun^; and of those, many i^
pear to be varieties of the tree ferns, wbieh constitute such nU'
meroua and splendid ornaments of trofncal forests. And there
can be little doubt but some of the luxuriant fronds, belon^ng
to this class, when detached from the parent stem, and found
thus petrified, may p«atly mislead an observer ; and, by being
regarded as separate plants, needlessly multi{dy the number of
^lecies. These arborescent filices must have been very abun-
dant, as numberless stems, of ciHisidecable magnitude, are to be
seen interspersed^ with the other small plants ; sometimes in-
deed so compressed, as to present nothing but a mere impres-
sion; but, occasionally, retaining a stalky rotundity, cX whitdi
the interior is converted into the enclosing stony matter, while
the cortical part is completely carbonised.
In the superior strata, which constitute these pseudo coal de-
posites, we observe, with only a few scattered exceptions, the re-
mains of the softer or herbaceous vegetables, as the Cydidefe,
Filiceaand Graminese ; while, at greater depths,, we find a dense
consolidated mass of vegetable matter in the true coal-fields :
From what cause can such undemating difference arise ? Can,
indeed, the latter be the trunks, — the timber of the primaeval fo-
rest overwhelmed under that enormous pressure; and the for.
mer, the surrounding herbaceous plants, prindpally growing in
loo^ and marsby ground along the outskirts of these woods P

higher line seems occaacnally to lie beneath one> in reality, iar
ita inferior in order ; and this especiaUy happens, whenever a
slide of the ^avelly diluvium has deicmded, so as also to cover
the intermediate deposites. And, in similar instances, where any

iuaon will be yet greater, and will demand no little stnctaeas <^

But here it is, that the vast excellency and usefulness are
shewn of the plan,laid down by M. Brongniart, in France, wvl
Mr William Smith, iu England, who shew that similar fossils
chancteriae similar formations, and thus give us the means of
determining the nature and place c^ any strata. By noting the
fxRUaioed petrifactions, an observer may thus readily pronounce
whether a mass, however displaced, belong to the highest oolite
or the lowest, or to the undeooniposed mivlstone. Another in-

Holy Writ, which t^l of a sudden and universal flow of waters

Geology demonstrates, by many irrefragable marks, every
where to be seen, that a mighty inundatiiMi has actually passed
aver all lands, apparently from north to south, at no very re-
nKri£ period, and covering the more solid beds of rock with a
varied depouljon of clay and sand, intermmgled with rounded
poeces of stcne detached froai masses at vast distances, and of
a very different nature &om any in the immediate vicimty.
In the diluvial depouta, for instance, of the coast of Yn^-
Aaie, may be found the granites of Cumberland and Scotland,

and jasper, also abound in the same ^veliy beds, bndcen' up
by Uie tides and wintry storms.
But in viewing such dilunal coverings of andent date and
extenave range, we miist be careful not to confound with them,
local and fwt later depoations, the e&cts of partial and general-
ly of fre^ water inundations. The bursting of s lake, the
change in the course of a riTcr, or the transitory passage of
some wintry torrent, leave a wreck behind them of gravel, mud,
and fraginents of stony masses swept from distant hills, which
may locally cover the strata for a short distance, and contain
hemes and shells far more recent thau those occurring in that
universally diffused gravel every where to be met with.
As in all sciences, so in geology, it is hard to say whether
more harm, more hinderance, have arisen from too great a spi-
rit <£ generalisation, or from views too partial and narrow.
Thus in the " Theory of the Earth,^ the first writers, led away
fay the fascinatioB of the subject, built up their cobweb reveries,

More recent geologists have perhaps erred on the other hand ;
and, dreading the ridicule and reproach attadied to their pre-
cursors, have amassed numerous and valuable materials, without
cm attempt to compare or to combine. The survey and obser-
vation of one district, or evenof one kingdom, will never suf-
fice ; the united and judicious comparison of many and distant
countries con alone lead to any thing like a grand, comprehen-
sive, and accurate map of the rocky structure of the earth. Par-
ticular hnks in the great series of strata may be lost or observed
in one country ; but this must be recufied by attentive surveys
of tbe order of poffltitm in another, and by what shades one ibr-'
mation passes into another.
When such enlaced views, such connected investigations of
tbe rocky bases of difierent countries shall have been made, we
may not still indeed possess a full and incontrovertible system of
all the changes which this planet has undergone, but we shall
have more precise and philosophical terms, whereby to denomi-
nate the strata and depositee originating from these changes ; and'

On the connection between the Phases of the Moon and Rainy
Days. By M. FLAOGEBstrfis.
T^HEai exists between the phaises of the moon and the rainy
days which coincide with these phases a constant relation, which
would appear very Angular, did not what we have observed of
the thermometer afford an explanation of it. From the calcu-
lation which I have made of the rainy days that have ccancided
with the days of the moon^s phases, and with those of the peri-
gee and apogee, during the period of nineteen years (froaa tbe

It ia seen by this table, that the numbers of rainy days which
coincide with the days of the moon's phases, and of the perigee
and apogee, follow the same progress as the mean heights of the
barometer corresponding to these phasra, but in the inverse ra-
tio. Thus the number of days of new moon on which it rained
is lesstthan the number of days of full moon on which it r^ned ;
and the mean height of the barometer, the day of the moon's
conjunction, is, on the contrary, greater than on the day of her
opposition. Inlikemanner, the number of rainy days that agreed
with the first quarter, much exceeds the aumb« of rainy days that
aoiDcided with the last quarter, and the mean height of the ba-
rometer is much less in the first quarter than in the last quar-
ter. Lasdy, the number of rwny days that have coincided with
the days on which the moon was perigee, is much greater than
the number of rainy days that corresponded with the days on
which she was apogee ; and, on the contrary, the mean height
of the barometer when the moon is perigee, is much less than
the mean height of that instrument when the moon is api^ee.
All this is perfectly explained, by the constant observation,
which has long been made, that it rains more frequently when
it is high. Thus, the superiority of the number of rainy days
corresponding to the full moon, in the first quarter and perigee,
over the number of rainy days that coincide with the new moon,
the last quarter and the apogee, arises from the circumstance
that the barometer is lower and the pressure of the atmosphere
less in these three fitst lunar periods, than in the three Ust.
Thus, all that can be concluded from our remark is, that the
diminution of the atmospheric pressure, caused by the moon's
attraction, must be reckoned among the causes that determine
the fall of nun. *

A Tour to the AmA of Prance and the Pyreneegy tn the year
less. By G. A. Walkek Akhotit, £sq. M. W. S. (Ccm-
tinned from a former Number).
Bdt it may be interesting to the botanist to have a marK par-
ticulsF account of these plaida ; oA in attonpting to do Rt, I
shall &Uo« aa neoily as poaable the rout*.
Near tbe entrance of the valley is situated the village of
Eynes, about an hour's w^ from the Cabanasse ; and socm af-
ter pasang it, We observed by tbe wAe of the path tbe beautiliil
Eryngium Bourga^ : the season was, however, acarcely enough
advanced for it. At the raouth of the valley, the meadows were
eavexed with NigrUdla anguttifbUa and PhaUtriffium tiUag-
tntm. Thb last, so often confounded in the heiharia with Ph. U~
Kago, is extremely distinct in the live state, the stamina being
declinate and curved, as in HemerocaiiUa, a circumstance which
has induced De Candolle to place it in that genus ; but the pe^
,rianth is divided to the base, which has induced Andryjosky to
make of it the new genus Cxackia. Few will, however, agree
to this : indeed, I do not see how it can be placed in a different
genus Irom Phalangium {Anthericum of Sprengel, whose genus
BvJbino contains the true Ajitherica, among which are A. plani-
JbHufn mid sefotinum). Having entered the valley, we passed
through a small wood, and ere long procured Vicia pyrenaica,
Pourr. (V. Fagonii, Lapeyr.), Lychnis alpma, DiAfmodon gtau-
cescena, and a. few others ; but we afterwards regretted our de-
lay there, as all these were much more abundant higher up the
valley. ' Leaving the wood, we found among some rocks a few
spetumens of Pedicularu cofiuaa, a beautiful species, widi fua-
culated roots and yellow flowers. From this to the Jasse de
Delmau (a shej^erd's hut in ruins), we kept alongrade of the
stream, and observed Cardtau carlinoidea and Stucyraga ad-
tcendena, {S. aquaHca, Lap.) in the water ; and on the nx:ks se-
veral other species of Sax^-agOy among which were no doubt
S. muacoidea, moichata, exarata, pubeacmt, mtertewta, mucta, and
several oth^^ of authors, but between which here, there were so
many hybrids or intermediate states, that we fouad it imposdble
Ml the spot to group them into species. Opponte to the Jawe
390 Mr Amott's Tou^ to the Sotak ^France
on the bulks of the stream, was the splendid GetUiana pyre-
notco, coming a ctHiaida^ble spac« with its deep blue lidofuonn.
This {jast was to me of extreme interest, as I had Wnved a
commkiDtcation ijpon it from my friend M. Guillemin of Paris, a
few days before I had left M ontpellier. *' The structure of the
fruit," says he, " is very remarkable : it is truly club-shaped
(dmMB/brmis) ; that is to aay, the ovary is upon a long pedicel,
and the capsule, tolerably ehort tuid round, sf^ts and forms two
refleetcd ktbes at the summit of the pedicel. This strui^ure al-
so ensts in G. aquatica from Caucasus, and in G. ae^blia &om
the Andes of Peru. ' M. Kunth, in his splendid work, figures
the latter, but is singularly mbtakeu in regarding the reflected
valves of the capsule as monstrous stigmas." Thou^ we saw
so much of this species in flower, and were able to see that the
ovary wa pedicellated, we oould not procure one plant with ma-
ture fruit.
Farther up the bank, but still oppomte to the Jasse de Tki.
mui, were OnonU rotimd^oUa, Linn. (Spec. PI. ed. 1. not ed. S.
which De Candolle has named O. tribracteata, and is perhaps
«itber a monsb-oaty or an ima^nary plant), Luxuia luUa, iStuA-
Jraga media, Veronka ophyUa, and thousands of Adonis pyre-
fudca. On this plant much discussion has taken place between
De CandoUe and Lapeyrouse ; the latter insisling on its being
the true A. ofimna, L., while the fanner declares that the plaat
of Limieeus is a variety of A. ventaiM, and that the A. pgre-
naica b not found in the Apenninet. But lately Professor Mori-
caud (Dec. PI. ItaL 6. p. 5. No. 58.) has actually met with a plant
on Monte Velino, which he calls A. apenina ; this is. also the A.
j^^uacaot Broccbi (Cent. 18S3), and scarcely difiers from the
plant of the Pyrenees : in both, the radical leaves are on long
petioles ; but in the Italian plant the petiole is not trifidj but
simple, and is dilated at the base into a sheaUi. In it, the pe-
tals are from 12 to 16, obovate and entire, and the carpels are
scabrous, not smooth, as in A. pyrenaica. I believe the Italiui
piant to he that of LinCEeus. .
Ft^lowing the course of the river, Phaca aatragtdiMt, Oxjf-
tropit monAma, and Htitckituia alpina, were every where abun-
dant. Papaver pgrawicum was also met with, but sparingly.

not suiHaently advanced to allow us to examine the structure
of the ^eeds, we referred it to the genus Ijepidium : it is indeed
aa intermediate spedes between L. campeatre and L. Airtwn *.
Here, too, we met with Draba aizoides, Linn, (not Dr. brachy-
stemoitt, DC. which alone is cultivated in Bntain as Dr. aisoi-
des'W Dr. mviUia and Dr. ItEvipes, DC. which, though per-

in having a perennial woody root, more oblong and leas tumid pouches, whose
tidet are tiflen very Anirir, and, when destitute of hMrs, are but obscurely dot-
ted, naver so scaly aa in that Bpedes. But £» a new and decinve character,
I am obliged to Mr Leatfaes, who justly observes, that the elongated style
pny'ecting far beyond the lobes of the pouch, will always distinguish this spe-
cies from the campeatre, whose short style is just equal to those lobes." With
the exception of the words above in Italics, which refer to the MontpeUier
plant, the whole of this applies most admiishly to our L. hetenjAj/Bum. The
L. Mrfum of Smith, however, has always, I believe, the leaves more or less
hairy, while that from the ValUe d'Eynes is quite glabrous. I am not, how-
- ever, inclined to think that a sufficient mark of difference, as we afterwards
met with the same plant in the TalUe d'Andorre with the leaves glabrous,
but the stem pilose, and at Mont Louis spedmens agreeing with those of
En^Mid in every retpect.
t This is also Dr. airoidei, Don, HoTt. BnU No. 186., and which Smith
(Eng. Flora, iii. p. 158.) says is the samewith that found in Wales. One spe-
cimen, indeed, I possess from M. Winch, and sufiposed to be native, is cer-
tainly identical with that cultivated, and seems to show that Wales is the pa-
Iria of our garden plant ; but unfortunately specimens in Dr Hooker's rich
■ herbarium prove that the Welsh and continental ones are the same.

We, however, took the more prudent plan, and tracked the mule

■ As we botanized the f<^lowing day in the valley of Querals,
we again saw profn^n of Gentiana pyrenaica ; we also fell in
with a few large tufts or cushions of Galium pyrenakum.
DaphoK coUkta, NigriteUa anguMi/blia, PediadaTtaJbliosa, and
Uanuncuhia aconitifbRua were observed ; and on a rock between
the Hermitage and the head of the valley, we got Lecanora
chr^sqleuca «, Ach. (with which L. Uparia fi, Ach. is identical),
and Androaace imbricata, DC. Much confu^^in has of late
arisen regardmg this species, and in their elaborate Systema,
Rcemer and Schultes seem to have increased it ; but the charac-
ters proposed by De Candolle are alone entitled to any r^ard ;
those ^ven by Lapeyrouse, and adopted by Sprengel, dp not
^pear to exist at all. At all events, the A, argtHiea, GtsxL
and Lapeyr. is the A. imbrieata, DC. and what we found at
Noun : it is covered with a close, white, starry pubesceace. Of
it I possess Swiss specimens, under various erroneous names, aa
Aretia helvetica, tomentosa, pubescens, &c. The A. brymdetr
DC. has the leaves, espe<nally towards th^r point, fumisbed
with umple, diaphanous, reflexed hiurs, which are apparently
gluunous. This, (^ which I have never seen a Pyrenean ^-

Tcry precipitous. We left the Cabfuiasse about four in the
morning, and, passing St Pierre, we kept to the right, in order
to examine that side of the great valley. A dense fog, however,
came on, so that, had we not studied well our course yest^day
from the windows of the inn, it is not [Hvbable we riiould have
attiuned our object ; and ailer, indeed, we did arrive in the vol-
ley,' we found the rocks so very shelving and nigged, that for
some time we gave up all Uioughts of attempting the summit.
We here sought with great attention for Globularia nudicaulist
which we did find, and Gl. punctata. Lap. indicated here, but
of which we saw no traces. Indeed, we were inclined to sus-
pect, from no botanist having sint^ met wi^ it, that it might be
either a variety of, or a hybrid between, Gl. cordifi)Ra and vtd-
garis *. At the head of the valley we saw Adonis pyrenaica,
Drifaa octopetala, and Saxifi-aga c^vgoefiilAa: SUene ciHata,
Veronica bellidifoliaf and CerasHum ^aberrimum. Lap. (pro-
bably a variety of C. o^ptRum), were occs^onally also observed.
About this time the weather cleared up a little, and we agiun
formed the resolution of scrambling to the top, which we finally
accomplished, not without difficulty and danger. We were,
however, reptud by finding on the summit of the ridge Saxi-
Jraga retuaa in abundance. This is generally esteemed a plant
of rarity, nor has this statitm been given for it : it can never
surely be mistaken for S. opposiii^ia, though at first m^t may
be overlooked for Jzalea procumbens, so glossy and compact
are its leaves. Passing the summit, and descending a little on
■ M.LBpeyraiuesajs that he himself found it here. If that were the cue,
it Is Btrange that in his own herbarium, which we had alterwardB an opportu-
nit; of examining at Tfaoulouse, there is but one miserable specimen, with-
out even the radical leases, and without any localilj. Lapejroose says that
he had since seen it in the herbarium of VaUlant, with the denomination
" B^iiai^na JianimaOTigani folia, Toum." a plant which is universallj allow-
ed to be GI.incDnetD«iu,Vlv. I see no reason why this plant maj not be found
in the warmer parts of the Pyrenees, as well as in Tuscany ; but I caimut
help suspecting that Lapeyrouse's specimen come firom Vaillaut's herbaiium,
and not from the mountain of Cambredazes. His long description evidently
belongs to Gt. moamaBena, and must have been taken from bett«T Efiedmens
than he himself was possessed o£ I think it also not Improbable, that, in
looking over Vaillant's herbarium, he conceived that he recognized a plant he
had formeri; seen at Cambredazes, but not gathered {supposing it at the time,

I. Dimovery of a Fofsil Walrut or Sea-Hor»e, t« Virginia.
In ihe Annals of the Lyceum of Natural History of New York
(No. 9. November 1827), there is a Beport by Messrs' MitchiU,
J. A. Smith, and Cooper, oa a portion of a fos^ skull sent to
Dr Mitchill, by Mr Cropper, of Accomac County, Virginia.
They found it to be the anterior part of the cranium of a spe-
cies of walrus. It compnses the entire sockets of the two great
tusks, the palatine and maxillary bones, with the sockets of eight
molar teeth ; and the bony isthmus, which, in this animal, con-
nects the tusks, remiuns, though much muuiated. Four of the
molares are also left, and one other has but recently dropped
out. From the appearance of the three remuning sockets, the
teeth must have been lost out of them at a very distant period,
and probably during the life of the animal. The tusk is re-
markably hiud and heavy, and no sutures are visible, except
between the palatal bones. The tusks have become almost
aga^sed, and th^r fracture is conchoidal, presenting a very
smooth surface, and a flinty colour and connstence. The frag-
ment bears the greatest resemblance to the analogous part of the
existing species, Trickecua rosmarvs. Dr Mitchill hopes yet
to succeed in obtaining an exact descripUon of the locality where
it was discovered. It bears marks of having been in salt water,
and IS «ajd to have been found on the sea-beach, where it has

II. 0» a Fosiil Ox from the MUtissipjn. By Mr J. E. Dekay.
In an interesting paper by Mr' J, £, Dekay, in the Annals of
the Lyceum of Katural History of New York, November 1827,
on a fragment of a fossil skull of the genus Bos, from the banks
of the Mississippi, he shews that it, in all probability, is part of
an extinct species, and the same as that found by Pallas in 1^-
beria. He concludes his memoir, which we reg^l our limits
will not allowus to give at full length at present, with the fol-
lowing inferences :
" That there formerly existed within the actual limits of the
iTnited Stiites, four, and probably five, species of the genus Bos.'
Of these, cmly one is at the present day found in our country
in a livii^ state. The Boa amer'uxmus, or bison, formerly ex-'
isting in great numbers in the states bordering on the Atlanuc,
is now driven to the boundless regions of the wesfj and ere long
will probably share the fate of the former companions of bis
race.
The second and third species (S. bominfroiu, and B. lattfrons)
have long since ce^ed to exist. Their specific diHerencee are
not yet completely ascertained ; but the animals seem to have
l)een numerous, if one may judge from the accounts of travel-

From tfae fact of their having been found associated with to-
msiiu of the mastodon and deer, it is presumed that they were
«o-«(iBtent with those speciea.
The fourth spedes is the Btu mo9chaius> From the teati-
moay of traveUers already cited, it has been ^ewn Uiat this spe^
cdes farmerly lived in Uie latitude of 40°, and even lower. It is
now confiaed witbio the limits of the Arctic Circle. They live
in berdsj feed on lichens, leaves of the willow, and are food of
mountainous rocky regions. The horns of the male, which are
lai^£f than those of the female, sometimes weigh sixty poutidl.
This Bpeiaes has been recently s^uirated by Blainville, from the
genus Bos, and forms the new genua Ovibos ; a divi^on which
does Dot seem to be gmeraUy adopted by subsequent natural-
ists.
U nder the name of Boa PaUasii, we would propose to desig-
nate the species to which we refer the fosEul crania of Pallas and
Ozeretskovsky, and proviuonally, the specimen from the banks
of the MisNssippi, whidi has given rige to the preceding remarks.
This animal was, as far as we know, an inhabitant of the ex-
treme northern regions of Europe and America. In the latter
country, its remains have been found as tow as 37° north, as tbe
locality of our specimen indicates. It was, doubtless, allied in
many parUculars to the musk-ox ; but from this, the observa^

III. On the identity of Ike Fostii Bones Jimnd in Georgia, United
State*, with those of the Megatherium of Paraguay.
Mr Cooper, in a paper read to the Lyceum of Natural His-
tory oS New York, January 18S7, informs us, Uiat, »nce a for-
mer communication on the subject of the Fosal Bones of Skida-
way I^nd, he had obtained, through the kindness of Dr Ha-
bersham, several other parts of the skeleton of the megatherium.
The collection last received consisted of numerous pieces, naariy
all fragments of the large bones of the extremities. They had
all marine shells adhering to them on the fractured surfaces, as
well as the others. Of these fragments, the author coafines his

SS6 On the IdenHttf of the Fosml Boneifmnd in Georgia,
remarks t^ a few, whose pecuTior coafortnatkHi renden than of
the greatest utility for comparison with the daaiptwiu and
figures of Cuvier and others. The first bone which he notiees,
is the united tibia and fibula. It was brtAeu into three {Heces,
which, when brought tt^tber, fonned neariy the entire bone.
On comparing it with the minute description of bone, and with
the figures recently published by Pander and D'Alten, the re-
stanbUnce was found to he,neflrly perfect This bone belonged
to the left ude. The following are its principal dimennons :
From the anterior border of the upper extremity to the
anterior border of the lower 84.1
From the posterior border of the upper extremity to the
podtenor point of the lower, 85.6
Breadth at its widest part, including the fibula, . . . 18L5
Breadth at its narrowest part, just below the foramen, . 10.4
These dimensions, he observes, agree sufficiently with thoeewbicb
Cuvier assists to the corresponding bcme of the megatherium.
The other portion, which he particularly notices, is one of the
metacarpal-bones, and quite perfect. On comparing it with the
bones of the megalonyx, of which there are good casts in the
Lyceum, he was immediately struck with its great itsemblaoce
to thiU which Cuvier considers as the metacarpal-boiie of the
middle-toe of the left fore-foot ; and a furUier examinatlaa satis-
fied him, that it was in fact the corresponding bone. Cuvier
speaks of the enormous size of the metacarpal-bones of the me>
galonyx ; but, enormous as they are, this of the m^atherium is
at least ten times as large. In other respects there is a great
general resemblance, though the bone irom Georgia is shorter
in prt^xirtion to its thickness and height ; and, from the appear-
ance of the vertical ridge at the lower extremity, could not have
admitted of as much motion as the articulation with the first
jdialanx. There is also in this ridge a pretty deep notch, which
is not found in the megalonyx. The author concludes with
stating, that a gentleman of Savannah is said to have in his pos-
session, from the same island, an entire lower maxillary-bcMie,
agreeing in ail respects with the description of the megatherium,
which, he remarks, must have belonged to a different individual '

thua shewing, that porta of at least two different skeletons of
this animal have been discovered in the United States.
On'^ Luminoumest of the Ocean.
. M. HE luminouaoess of Uie ocean is one of the most beautiful
phenomena of nature, which excites surprise, althoi^^, for*^
months together, it may be seen evny night. The sea is pho^
phorescent in all latitudes ; but he who has not witnessed thu
f^ienomenon in the torrid zone, and e^tecially in the Pad£c
Ocean, can iona hut an imperfect idea of the magnificence of
such a spectacle. When a vessel of war, impelled by a iresh'
breeze, cleaves v the foamy waves, and one is stationed near the
shrouds, he cannot be satisfied with viewing the beautiful jdie-
nomenon which pres^its itself. Every time that the mde of the
ship, as she rolls, emerges from the water, flashes of reddish
light seem to issue from the keel, and dart toward the surface
aS the sea. X^ Geotil * and the elder Forster +,^explmned the
appearance of these flakes by the electrical friction of the water
against the body of the advancing ship^ But in the present
state c^ our knowledge, this explanation is no longer admissible.
There are few points of natural history respectjog which there
have been so many disputes as the light emitted by the waters
of the ocean. What we know with predsion on the sabject, re-
duces its^ to the following facts. There are various shining
molluBea which, during their life, emit at pleasure a rather weak
phosphoric light, generally of a bluish colour. This is observed
in the Nereis noctiiuca, the Medusa pelagica, var. fi I, and the
Monophora noctHuca, discovered during Captain Baudin's expe-
dition ||. Of this number aie also the microscopic animals,
which have not as yet been determined, and which Forster saw>

of Good Hope. The lummouHieis of sea water is KNuetimes
eccaaoiied by these living lanterns. I say sometimes ; for, in
most cases, notvitfastanditig the use of magiufying glasses^ no
animal is perceived in luminous water ; and yet, whenever the
wave happens to strike a hard ixxly and breaks, producing foam,
and whenever the water is strongly a^tated, a li(^t is produced
resembling a flash of lightning. This phenomentxi probably
originates ftom the decomposed fibrils of dead m<^usca whidi
exist in infinite quantity in the d^iths of the sea. When this
luminous water is passed throu^ a pece of d^ise cloth, these
fibrils are sometimes detached frmn it under the form t^ lumi-
nous points. When we bathed in the evening in the Gulf (rf*
Cariaco, near Cumana, some ports of our boi^es remained lumi-
nous on ooming out of the water. The luminous fibres stuck to
the skin. From the immense quantity of molLusca dupersed
through all the seas of the torrid zone, it need not be surpnsing
that the water of the sea is luminous, even when no (H-gamc
matter can be sepunted from it. The infinite division of all the
dead bodies of dagyses * and medusce may render the entire sea
capable of being conadered as a gelatinous fluid, uid which is in
consequence luminous, has a nauseous taste, cannot be drunk by
man, but affords nouiishment to many fishes. If a board be
rubbed with a pan of the body of the Medusa hysocella, the
place rubbed becomes luminous whenever the finger, well dried,
is passed over it. During my passage to South America, I
sometimes put a medusa on a tin plate. If I struck the plate
with another metal, the smallest vibrations of the tin were sut
fident to make the animal shine. How did the blow and the
vibration act in this case P Was the temperature instanlaneous-
iy raised F Were new surfaces uncovered, or did the blow
make the pbosphuretted hydrogen gas escape, so that, craning
into contact with the oxygen of the atmosphere, or with the wa-
ter of the sea, it produced combustion P This effect of the blow
which exdtes the light is particularly striking in a jumbling sea,
when tJie waves dash against each other in all directions. Be-
tween the tropics, I have seen the sea luminous at all tempera-
tures; but it was more so before storms, or when the sky was

luminous animus only come to the surface of the sea when the

with reason, why our fresh marsh-water, which is filled with po-
lypi, is not luminous P It would appear in fact, that a particu-
lar mixture of orgauic particles is necessary to favour this dis-
engagement of light. Willow^wood is more phospboivsc^it
than oak. In England, salt-water has been rendered luminous
by casting herring brine into it. Galvanic experiments shew
that the luminous state of living animals depends upon an irri-.
tatioa of the nerves. I, have seen an Elater noctilucus, which
died, diffuse a strong glow when I touched its ailterior extremi-
Ues with tin or «lver. Sometimes, also, the medusse give out a
stronger light at the moment when the galvanic chain is closed.

these organs, to which he was led by new observatioas, difiereitt
from any previously made on the subject.
The differences which the author establides in his first me-
Wfox betireeD hairs and feathers, were founded on the circum-
stance, that hairs are produced by the exhatation of the matter
which is secreted by the nervous papillse, which serve successivdy
as a mould to each of their parts, while the formation of feathers
was more complicated, acceding to his idea:^ and the presence of
a pulicular organ rendered necessary, which he named the Pro-
ducktgCapmle(Cap3uieprodti€trice.) This capsule is the result
of a spontaneous and transitory creation, analogous to that which
gives rise to the horns of the stag, of whose future forms, or
even existence, no indication is presented previous to their ap-
pearance. The producing capsule of the feathers is farmed ab-
solutely in the same manner on the dermic papilla, which in-
deed furnishes it with a base, and contributes to its development
by the enlargement of its proper vessels ; but, without the cap-
sule having more connection with the papilla thau any parts of
organized bodies have which assumed their points of departure
from those which have preceded them. A circumstance which
has undoubtedly prevented naturalists hitherto from being ac-
quainted with the producing oigan of the lieathers, is, that it
continually varies, and that only a small pc»lion of it can he ob-
served at once. The part which has secreted the first pcation
of a feather is obliterated, in fact, the moment this portion U
formed, and the part which is to follow makes its appearance.
This, again, which will produce the second portion, is obliterat-
ed in its turn, as soon as it has answered its purpose ; and this
process continues until the feather is completed. It is therefore
seen, that the producing capsule, could the parts of which it is
successively formed be united, would necessarily equal the fea-
ther itself in length. If we now reflect that there are Inrds in
whidi the feathers are renewed every year, in a few days as it
were, and that, of these feathers, there are some which have a
length of several feet, an idea will be formed of the importance
which at this period the twofold formation of the capsule and
^ther acquires ; and hence the most satisfactory explanation
of the accidents which in birds accompany the casting aad de- -
velopmmt of the feathers at the period of moulting.

Observatvms on the Strudure of feathers and Hair. SSS-
M. Frederick Cuvier, in his seccmd memoir, has commenced
his inquiries respecting the devek^nnent of hairs with the quills
ot the porcupine, which are, in reality, nothing but \oag bain,
but whose structure is more apparent, and their producing or-
gan mca« eanly examined.
He here establishes a perfect anaic^ between prii^les and
feathers. Both are produced by the same organs, and are sub-
jected to the same mode of growth. In the pricldes, as in fea^
thers, the homy matter is produced by the membrane of a
sheath, and the spongy matter by the surface of a bulb ; and it
is exctuavdy irom the form of these same orgaos that the form
at the prickles result, which, like the feathers, are produced in
a real mould.
Hairs do not, as was hitherto supposed, form an essential part
of. the skin. They have a principle of existence of their own,
and belong to a system of organs not less remarkable, sometimes,
for its complexity than for its development. This system may
he associated, with the dermis, and be developed in different
jXHDts of its substance ; but even then, it is not confounded with
that organ, but preserves its peculiar nature.
M. Cuvier concludes from this, that the hair has never hither-
to occujned the rank which is due to it in zoolo^cal systems.
He confers the organic system which produces the hairs as
analt^us to that of the senses, and even as forming port of it ;
fin- in a great number of animals the hairs are a v^ deUcate
organ of touch. The slightest touch, even that produced by a
hair of the human head, is sufHdent to make certain animals,
cats for example, contract their skin and make it tremble, as
they always do to rid it of light bodies which stick to it, and of
whose presence they are apprised by this peculiar sense of
touch.
M. Cuvier concludes bis interesting memoir with explaining
a disease, the nature of which has hitherto been involved in the
greatest obscurity. We mean the Plica. The two singular
^uid distinct affection^ which are de^gnated by this name, oon-
fflst, the one, of on excessive development of the hair ; the other,

Althodgh the memoir refers, in a great measure to Dr Eich-
hom^s work od the skin, it contains, besides, much curious infor-
mation. M. Weber first remarks, that the infundibulifomi
fossEe on tht5 prominent lines of the palm of the hand, were de-
scribed and figured as being the pores of the sweat, by the cele-
brated Grew, in the Philosophical Transactions for ]684i, p. 566.
M; Eichhom cannot, therefore, claim to himself the merit of
their first discovery.
On raising horizontally from the palm of the hand, with a
sharp razor, a layer of epidermis, more or less thick, we find the
inner surface of this layer, not smooth, but traversed by furrows
and elevated lines, resembling those of the outer surface, and
corresponding exactly to them, so that a prominent line at the
outer surface answers to a furrow on the inner, and vice versa ;
while to the infundibuliform pits of the outer surface there cor-
respond internally, small rounded oval or convex prominences,
arranged in rows along the furrows. As the same thing. is ob-
served,, whatever may be the thickness of the layer of epidermis
raised, the author concludes that the epidermis is composed of
an assemblage of thin layers, superimposed upon each other,
and agglutinated leather, — a. structure which many anatomists
have already admitted as the most probable.
Passing to the examination of the Sebaceotis Ji^cles, the
author maintains, contrary to Dr Eichhom''s opinion, that these
follicles form organs distinct from the bulbs of the h^rs, and
that they exist in the whole extent of the skin, with the excep-
tion of the palms and soles. The bulbs of lat^ h^rs have their
seat in the deepest layer of the dermis, and penetrate as far as
the subcutaneous adipose tissue. The sebaceous follicles, on the
contrary, are placed nearer the surface of the skin, and are ne-
(Atervatiant on thf Structure of Human Hair. 3d5
ver found in the adipose layer ; nor can they be confounded with
Hoe bulb» of the hairs, th^ az& being much larger thui thtars.
Lastly, the structure of these organs is very difiereut. In new-
ly born children, the. sebaceouB ft^cles may be dJscorered on
all parts of the body, excepting >he tw> mendcHied. They are
particularly lai^ in the skin of the scrotum. Each of these
follicles is composed of four or five compartments, or cellules,
a^^omerated tt^ether. Their tranaverse diametet: is greater
thiui that which extends from the bottom of the excretory ori-
fice. The greatest transverse diameter observed by the author
was three-fourths of a line.
The great develt^ment which the sebaceous follicles assume
in the parts of the skin which are affected with cancer or fun-
gus, also fumishes a proof of their existing over the whtJe ex-
tent of the skin.
In microscopical researches respecting the structure of hairs,
it is of advantage to make use of a single lens, with a very small
focus (from one-fourth of a hne to a line), in place of the com-
pound microscope, which often gives rise to error, in making
mere inequalities existing at the surface of the skin to be con~
founded with internal cellules. The transverse section of the
hairs should also be carefully examined. For this purpose, the
hair is placed on a piece of smooth paper, on which several pa-
rallel lines cut each other at right angles. The hair is fixed by
its two extremities with wax, and is cut with a very sharp razor,
placed in the direction of one of the lines which fall perpendi-
cularly on the hair, and with the edge directed vertically toward
the paper. Thus prepared, the hair presents its transverse sec-
tioii in a very distinct manner. From inquiries made in this
manner, the author concludes, that the human hair has neither
a canal in its interi(»:, nor a cellular structure ; an opmion al-
ready pven out by Rudolphi, but contradicted by M. Henun-
ger. It is otherwise with the hairs of the roe, they presenting,
in whatever manner they are examined, hexagonal cells, whose
diameter is placed transversely. But this hak difiWs&om that
of man in many other pn^rties. There are no cellules in the
woolly hur of the sheep.
The form of the human hair is rarely cylindrical. It appears

don is elliptical or oval. The flattened form appears to be ne-
cessary to the curling of the hairs, and the cylindrical figure
seems to rorm an obstacle to it In Negroes, the hurs present
a very marked flattening. In the wool of the sheep, wfatcb ap-
pears to be cylindtical, another cause probably gives rise to the
phenomenon of curling ; namely, the transverse inequalities with
wbkh the surface of the hairs is furrowed.
The author gives four tables of micrometrical measuroiients
of the hairs of the white man and Negro. In the numerous ob-
servations which he made, he sometimes found these parts ul-
cerated, as it were, at their surface, like carious teeth. The
hairs of the back of the hand frequently break at some distance
from their pcnnt. This rupture appears to be a normal pheno-
menon, which nature employs to prevent these hairs from be-
coming elongated beyond measure. At the place of rupture,
there are observed small interlaced fibrils, which for some time
retain, in contact, the two ends placed tt^ether at a ri^t ui^,
until their detached extremity at lengdi falb.
The author has also made some experimenta on the' etastidty
of the human h^r. It may be elongated about a third of it&
length. The ccotractjon which follows is somewhat less ; the
hair of the roe has scarcely any extensibility, and breaks with
the greatest ease. It has more anak^ to the feather of alnrd
than to human hair.
On the Level of the Sea.
It is well known that the ocean retains the same tevd in the*
de^ banBE of the sea, and that its vast surface preserves a
permanent form all around the globe. If it be raised by ten-
pests it is reduced by equilibrium within the limits which are-
aaiigned to it. If the earth, as Fouillet remarks *, were im-
moveaUe, and formed of homcgeneous strata, the surface of the
sea would be strictly sphericaL The navigators who pass under

the pole, would all be at the same distance from the earth's centre.
This would be the state of things in ctOTsequence of the laws of
hydrostatics, and the structure of the solid parts of the globe,
which presents trilling inequalities at the surface. Greatinequa-
lities in the solid parts would disturb the sphericity of the liquid
surfaces. Were the chain of the Cordilleras only a hundred
times hi^er, the waters would rise on the coasts of America, on
the eastern as well as the western side; and would occupy a
lower level on the opposite coasts, leaving the ports of France
dry, as well as those of Japan.
If the earth were stationary, and formed externally of hetero-
geneous partsof very unequal density ; if, for example, under the
Atlantic Ocean, between the crust which forms its bottom, and
the centre of the earth, there should occur vast cavities, empty^
or filled with substances of small density, it is evident that the
intensity of the attraction of gravitation would be much less on
the waters of the Atlantic, than those of the other seas, and that
then the general surface of the waters, instead of being every-
where spherical, would be raised in some parts, and depressed in
others. Thus, a helen^neousness of substances might of itself
produce irregularities of form, and if to this cause there be add-
ed the influence of the centrifugal force, it will be seen that the
question becomes still more complicated. In our present state
of ignorance respecting the internal structure of the globe, in-
to which', with all our power, we are only able to penetrate to a
very trifling depth, the only means which we have of finding
the true form of the surface of the seas, are geodesical operations,
and observations with the pendulum. By the first of these
means we arrive at a knowledge of the fact, independently of
all hypothesis and of all explanation ; and by the other we shall
perhaps be able to discover some general laws of the internal
structure of the earth, or at least some of the local causes that
may alter the regularity of its surface. The equilibrium of the
waters depends upon the direction of gravity, and the oscilla-
tions of the pendulum depend upon the intensity of the same force.
It is difficult to discover a priori in what degree these two ele-
ments are connected together, and to what extent they may be
determined by each other ; and it is this that gives still more im-

poitance to the inquiries whose object is to determine them with
Accuracy.
Almost alt the bauns of the sea communicate in various ways,
i^wther by wide canala, or by more or less contracted straits ;
and the waters in these different basins are subjected to the con-
ditimta of equilibrium of communicating vessels. Only it must
be observed that the water of the sea is not a homogeneous liquid
in the whole extent of the mass: the temperature changes with the
latitude; anditalsochanges with the depth; thed^reeof saltness
changes in like manner ; and all these causes make the dendty to
vary in the different places, and from this there results a multitude
of moti(H)s, by which the equilibiium tends to be kept up. The
water of the Atlantic flows into the Mediterranean by the Strmts
of Gibraltar, as is proved by the rapid current existing there;
but it is not known whether, by an opposite current existing at
a greater depth, the water of the Mediterranean may not pass
into the ocean. If this second current exists, they are both with.-
out doubt produced by the difference of density in the layers of
water. If it does not exist, it must be supposed that the Me^
diterranean loses by evaporation, or by other causes, more water
than it receives by the Nile, the Rhone, the Danube, and all the
rivers that empty themselves into it, and that the Atlantic Ocean
makes up the loss, in order to keep it at the height required
for equilibrium.
The following are the results that have hitherto been obtained
respecting the level of the seas. During the French Expedition
to Egypt, a commission of engineers, under the direction of M,
Le Pere, determined the relative heights of the Red Sea, and
Mediterranean. This operation is worthy of great confidence ;
and, for result, it gives a very remarkable difference of level be-
tween these two seas, which are so near each other at the Isth-
iniis of Suez, and which, beades, communicate with the Ocean.
At low water theRed Seals Smetres 12'' above the Mediterranean,
and at high water its excess of height rises to 9 metres 9". Thus is
confirmed the opinion of the ancients respecting the danger of
npening up a communication between the two seas. At the pre-
sent day, a great part of Egypt would be submersed by the
Eed Sea ; and yet the bed of the Nile and the soil of Egypt are
constantly raised by the deposit of m_ud which every succeeding
inundation leaves. M. Girard has made very curious inquiries

into ihis »ul>ject. By taking the present hei^t of the floods,
at the Nilometere of £le[Aantina, and of the Isltmd of Roodfth,
and comparing it with what it formerly was, he found the mea-
sure of the elevation of the ground, which he estimates at 136
millimetres in- the century. Considering it as such, it would
still require many centuries to bring Lower £gypt merely to the
level of the Bed Sea *.
In the course of the operaticms for measuriug the meridian in .
France, M. Delambre calculated the h^ht of Rodez above the
level of the Mediterranean Sea at Barcelona, and its height above
the ocean, which waslies the foot of the tower of Dunkirk. These
two heights are equal to a fraction of a metre ; whence it follows
that if there does exist some difference of level between the Me-
diterranean Sea at Barcelona, and the Atlanuc Ocean at Dun-
kirk, the difference is at least very small.
M. de Humboldt, in his journey in America, made barotne-
'trical observations on the shores of ihe Atlantic Ocean, and on
those of the South Sea, from which some knowledge may be de-
rived respecting the relative height of these two seas. From ba-
rometrical means taken on the one hand at Carthagena, Cumana,
and Vera Cruz, on the east coast of Mexico, and on the other
hand, at Callao and Acapulco, on the shores of the South Sea,
it would result that the South Sea is about seven metres higher
than the Atlantic. Other observations made by M. Humboldt
would give a somewhat greater difference ; but that celebrated
traveller gives the above results only as a first approximation,
supposing that the unequal heights of the tides, the difi'erent
.hours in harbours, and the greater or less extent of the horary
variations of the barometer, are so many causes which may have
an influence upon such delicate measurements.
The level of the Caspian Sea has been the object of several
recent inquiries. It was deleriiiined in 1818, by MM. d'Engle-
, hardt and Parrot, in their curious journey to Caucasus and in
the Crimea; by M. Pansner, in 1816; and about the same time
by M. Wisniewski, who published, in the Petersburg Memoirs,
' In a former Dumber of tbi? Journal, theie is an interesting view of the
French obiiervations on the comparative level of the Red Sea, and the Medi-
terranean Sen.

the series of observations which he made with the same ohject
in 181S. All these measurements agree in pladng the level of
the Caspian Sea much henesth the level of the Black Sea. Ac-
cording to the mean result, this difference may be estimated at
100 metres, or about 3S5 feet. Yet along the shoces of the Cas-
pian Sea, and to a great distance from its present banks, there
are striking proofs to be seen of the abode of salt water. The
nature of the. ^ound, its form and chemical composition, the
remains of shells, and the skeletons ofRshes, with which it is fil-
led, seem to leave no doubt remEuning, that the sea formerly
covered all these steppes to a distance uf several hundred leagues.
How has the depres^on of level which is now observed been pro-
duced ? What is become of the mass of water which is wanting,

- The mixture of the water of rivers with that of the sea,
also presents some hydrostaticat phenomena, which it is curious
enough to observe. Fresh water being lighter, ought to keep
at the surface, while the salt water, from its weight, should form
the deepest strata. This,. in fact, is what Mr Stevenson obser-
ved in 1818, in the harbour of Aberdeen, at the mouth of the
Dee, and also in the Thames near London and Woolwich. By
taking up water from different depths, with an instrument in-
vented for the purpose, Mr Stevenson found that, at a certain
distance from the mouth, the water is fresh in the whole depth,
even during the flow of the tide, hut that a little nearer the sea,
fresh water is found at the surface, while the lower strata con-
sists of sea water. According to his observations, it is between
London and Woolwich, that the saitness of the bottom begins
to be perceptible. Thus, below Woolwich, the Thames, in place
of flowing upon a solid bottom really flows upon the liquid bottom
formed by the water of the sea, with which it is no doubt more or
less mixed. Mr Stevenson, however, is of opinion, that, at the
flow of the tide, the fresh water is raised, as it were, in a single
mass, by the salt water which flows in, and which ascends the bed
of the river, while the fresh water continues to flow toward the setf.

These experiments tend to confirm the ojnnion given out by
Franklin on this subject, in 1761. " If some rivers," says he, "
empty themselves into lakes, without the latter ever overflowing
their banks, it is because the water is then spread out under so
large a surface, that there is d^ly removed by evaporation a mass
of liquid about equal to that which flows in. But there are rivers
which, from the extent of their course, and the In'eadth of th^
mouth, may be compared to lakes. To ccHnplele the .resem-
blance, it would only be necessary that a dike should stt^ : the
course of the water, and prevent it from being emptied into the
sea. There would then occur some diflerences of level, accord-
ing to the seasons ; but in general, under certain <»rcumstances,
these differaices would be confined widiin narrow limits. Al-
though the ccHUinunicatioD between the river and the sea be
open, it may be supposed that the dike d! which we have been
speaking, really esists in the surfoce of junction of the fresh
water and salt water. Only this dike would be moveable ; it
would ascend a certain number' of miles with the tide, and after-
wards descend. The extent of the excuruons would vary with
the v(Jume of the water. In some cases, we might also ex-
pect to find the sea water, and that of the river, minted
together on meeting, and this to a greater or less extent, from
the twofold e£Eect of their modons, and of the difference <^ their
specific gravities ; but at a certiun distance from the mouth, the
fresh water, first carried down by the current, and again thrown
back by the Ude, would oscillate nearly within the same lunits,
without even reaching the sea. An ignorant person would inta-
ke that the water flowed off, and, was partly lost through
some crevices in the earth, while in reality it is by the air that
it escapes.

Mr Rengger some time ago gave an account of the auriferous
sand of the Aar, the Emme, and the Ilsis, in Switzerland, which
he had an opportunity of observing himself. It occurs diffused in
the sand and gravel of the bottom of the valleys watered by these
rivers. When the height of the water occasions the river to
carry off part of its banks, the auriferous sand is deposited at
the first place where the rapidity of the current finds an <^
stacle. The sand, after it has been deprived of the lifter
parts, such as clay, calcareous earth, &c. consists of small grains
or plates of gold, magnetic iron, zircon, garnet, s]:anelle, &c.
The Aar, from its exit from the Lake of Thun to its arrival
at Jura, flows only through sandstone mountains, as is also the
case with the streiuns which it recrives in its course. The
Beuss and the Limmat have deported the debris of the Alps
in the bottom of a lake The only exceptions are the Saune,
the two Emmes, and the Sihl, which rise in the alpine limestone.
The sandstone and coal d^iosits appear, therefore, to be the beds
from whence the different parts of the auriferous sand have been
carried into the basin of the Aar,
The author has analyzed varieties of sandstone from different
countries, as from Stieffelhacb, Me^enwyl, and Bollingen, and
found magnetic iron in them. He presented to the meeting
of Naturalists in Zurich grains of iron taken from pulverieed
sandstone from the latter place. If the proportion of the gold
to the iron be taken as a scale, the former must occur in this
standstone in so small quantity, that a trial made on the large
scale alone could succeed in extracting it.
H. Ronlein, howev^, some years ago, found gold in the
sandy marl which belongs to this formation ; uid smalt aoales
of gold have been observed in the pebbles of nagelfieh quwtz
of the same formation. The constituent parts of the auri-
ferous sand seem to have been brought together from sand-
stone mountiuns, and deposited by natural washing. This
washing had undoubtedly commenced during the excavation of
the valleys. The heavy parts of the broken-down matrix re-
mained, the light parts were carried farther, and the parts of
Oie auriferous sand, after traverring large tracks of ground,
and after a long series of ages, were gradually compacted, until
at last they appeared under the form of mud. The opiraon
or Gold Sand met tffUh in Rivert. 343
generally ratertained by goLd-hunters is, that it is only in the
andenc bottcans of valleyB that auriferous sands occur, and that
the recently submersed countries never furnish any.
From all that we have siud, it follows that the sandstone for-
mation is the immediate source of the auriferous saod of the
Aar. Toward the Rhine, on the other hand, where gold-wash-
ing was formerly vigorous, espedally near Coire and Mayen-
feld, there are no traces of sandstone mountains, at least in this
part of the basin of the Rhine. The gold must here have been
immediately derived from its ori^nal site, the trancition lime-
aUme mounbuns of the Alps. There is seen, among others, a
place of this kind toward the eastern declivity of the Galanda, •
at the foot of which the Rhine flows, and where, at Tarious pe-
riods, attempts were made to form establishments for the extrac-
tion of gold.

" 1. From a carefal examination of those Comeu n-hose motions are
exactly known, on their aucceBaive returna to the perihelion, much va*
luable inforination of a different nature may be obtained ; For, if they
happen to have undei^one any change in their physical constitution,
during the period of Uieir shsence, that change will probably be indica-
ted by a corresponding Tariation in their appearance. Since the ef-
fect of the Holar power is so great (whatever be the mode of its opera-
tion) in pushing away the nebulonx matter of the Comet, into the form
of a tail, it has been supposed that some of this nebnlous matter may
even be alh^ether detached from the attraction of the nucleus, so as to
cause a gradual diminution in the Comet's substance ; and this effect, it
ia obvious, will be the more easily produced, if the graritaliun of the ne-
holous particles to the nucleus be weakened by a rotatory motion of the
Comet. Now, an attentive examination of those Comets, whose ap-
proaches to the sun at the perihelion are near in respect of distance, and
frequent in respect of time, may enable us to judge whether or not this
supposition be well founded. But this ia a point to which the attention
of astronoinera has been too recently directed, to be yet very satisfacto-
rily fixed. Numeroua data are requisite, which a constant and careful
observation can alone supply, before any decisive result can be obtained.
But certainly the observations of astronomers, as far as thev have been
made, with regard both to the diminished size of the nucleus of all co-
mets atier a perihelion passage, and the inferior brilliancy of Honey's in
particular, at its last appearance *, aeema to confirm what other consi-
derations abundantly suggest, that a partial abstraction of nebulous mat-
ter does take place at every approximation of a comet to the sun.
" The qnestion, therefore, very naturally occurs, whether a Comet,
after a long succession of revolutions, will not be liable to become alto-
gether annihilated by tliia dispersion of its nebulous matter? Herscbel's
opinion respecting the constitution and formation of comets, here de-

846 Mr Milne's Prize Eisa^ on Comets,
now propoied. There is no indiridual perhaps in the unrials or astrono-
my who has cootribiited more to our knowledge of the lipaveiia than Sir
William Herachel, both by extending the limits of our Tision into the
most distaDt parts of the universe, and by iDresIipting the laws which
goTem the more cotnplirated phenomena of natnre. But of all hie con-
tribuuons to the scieace, none are so important in themselTes, or so well
calculated to disclose to us the secret and marTellons operations going
on in the workshop of Nature, as the discoTeries which he has nrnde
concerning nebnln. Thew Debnlee, it is snppoeed, are formed by the
partial condensa^on of matter, proltably the etherial medium itself dif-
fused- ibronghoiit theT nnirerse ; enil chat their number must be prodi-
gious, is sufficiently proved by the &ct, that Herachel, by bis own ef>
fort* alone, discovered 200O of them. Some of the nebuin are found
to have so strong a resemblance tu many comets, which, on account of
their distance from the sun, can just be discerned from the earth, that
they are n»t unfrequestly confounded * ; and it is only by a nearer ap-
proach, or by an intimate acquaintance with all the nebuUa in the same
quarter of the heavens, tiiat astronomers are able to distinguish them.
Now, it is the opinion of Herachel, and his opinion is strongly sup-
ported by the authority of La Place f , that Comets are originally minute
nebulffi, which, by the continual approximation of their particles, have
at lengtli acquired such a degree of density, as to be capable of being
attracted by the sun, and of describing an orbit of their own. As the
nebulous mass approaches the sun, one result, as we have seen, is the
ej^nsiou of its parts, and their prolongation into what has been termed
the Tail : But, another result, according to HersrJiel, and one no less
imporlalit, isa gradual consolidation of the nebulous matter by the agency
of the solar heat, " It is admitted ou all hands," says he, " that the act of
" shining denotes m decomposition, in which at least light is given out;
but that many other elastic volatile subetancea escape at the same time,
especially in so high a d^ree of rarefaction, is tar from improh^le.
Since light then, certainly, and very likely other subtile fluids alto,
escape in great abnadaace during a cAnsideiable time before and ttui a
comet'a nearest approach lo the sun, 1 look," says Herachel, '■ iqton a
perihelion passage in some d^ee as an act of consolidation ^."
■ " By the gradual increase of the distance of our Comet," says Herschel,
speaking of the Comet of IS07, " we have seen that it assumed the eemhiance
of a nebula ( and it is certtuo, thai had I met with it in one of tn j eveeps of
the zones of Uie heavens, as it appeared on eitlier of the days betwem the
8th December and the 8Ut Frtruary, it would have been put down in the

" II. This procesH of ronBolidation will eri<tend}' be the more power-
ful, the more that the Comet is «nb|ected to the enn'ii calorific actioD;
a cooditioD which depends upon two circumsEancea ; one, the perihelion
distance of the Comet, the other, the time in which it completes its re-
volution. It folloWB from thia CDnsideration, that we may be able eveo
to estimate the degree of solidity which Comets have attnioed, (imply
by taking into account these two circnmaianws ; htkI a reference to ob-
servatJoD will at once shew whether or Dot the theory be correct. But
before attempting to apply this test, one remarlc must be made, which
abews that the application of it may not in all cases be coDclnsive.- If
all Comets during ibeir successive revolutions round the sun, leere to
remain totally exempt from the possibility of receiving any accession of
foreign matter, tending to enlarge their hulk, then we might expect that
the consideration of their perihelion distance and their period of I'evolu-
tioD should always correspond with the amount of their solidity, or, in
other words, the actual size of their nucleus. But if we suppose with
Herscbel, Lb Place, and other eminent asUonomera, that there exist
multitudes of nebula throughout space in every different stage of matu-
rity, from those whose formation has just commenced, to those whose
condensatioa by the attraction of the particles has already so far ad-
vanced, as will Boon render them capable of gravitating towards the smi,
we nuBt reckon it not impossible that Comets, in the extensive range of
their orbtta, may occasionally meet with some of these nebulce, and thus
cany with them a new supply of uuperibelioned matter in their next
approach to the centre of the system. Id this manner, the loss of sub-
stance to which, as we have above remarked, comets are exposed, bv vo-
iHtilieaticHi, may possibly be restored ; white, in process of time, they may
aeqnire a magDitude and solidity conBiderably enrpassing what could have
ariaeu from the primitive quantity of their nebulotn matter. Certainly
wie are not at liberty to suppotM, tW this fortuitout junction of a comet
with nebnlw takes place frequently ; btit, in estimating the consolidation
of difierent Cnmeta, in order to find whether die result correspoods wiA
what the frequency and neameaa of their approach to the sun wovU
lead us to expect, we ought to recollect that the test is not infelliUe,
from the poesibility of an aoeeseion of nebulous matter Inrnng occurred
in the mannw we have dow deaOribed.
" HWsobel'e tlieary, with reapect to the agency of die Mtar heu, in
promoting the coDsotidation of comets, necessarily implies, that the en-
velope and tul gradually become less extensive, and that the nucleus,
upon whose snrfece the nebulous matter consolidates, gradually in-
creases in magnitude. In these respects, therefore, some difference
ought to be indicated by the physical appearance of those comets whose

perihelion distances end periods of revolution are not the Mme ; a con-
dition confirmed by the exaninaticm of eeveral, that hare been the most
attentively observed. The second Comet of 1811 had a nucleus, which,
acconling to the continental astronomers, amounted to 570 miles * ;
while its tail was 500,000 miles in length. The Comet of 1807 poe-
seBsed a nucleus of less size, bnt a tail of greater brilliancy ; the diame-
ter of the one being only 538 miles, the length of the other ^,000,000.
The first Comet of 1811, which, from its splendid appearance, has been
termed the great Comet of 1811, was observed to have a smaller nu-
cleus ; but, on the otber hand, its envelope and tail were far more ex-
tensive : the diameter of its nucleus was 4SS miles, and its tail stretched
out nt> less than 133,000,000 of miles. The first of these three comets,
then, according to Herschel's theory, must have been subjected in a
mncli greater degree to the consolidating influence of the sun's teat
than udier of the other two, seeing that it had the largest nucleus, and
the least quantity of nebnlous matter: and the like result ought to be
indicated with respect to sll the three comets, on a comparison of their
respective periods and perihelion distances. The periodical revolution
of the great Comet of 1811 is found to be 3383 years, and it approaches
1.55 nearer the sun at ite perihelion, than the other Comet of 1811 :
the product of these two numbers is 5243. The periodical revolution
-of the Comet of 1807 is 1713 years, and its perihelion distance is 3.4<6
times less than that of the seiMind Comet of 181 1 : the product of these
two numbers is 4213. The periodical revolution of the second Comet
of 1811, whose perihelion distance we have taken equal to 1 as the
standard of comparison, is 875 yews. These numbers, then, 5243,
4213, 875, representing inversely the result of the sun's long continaed
action upon. the nebulous matt« of the three comets, correspond T«y
nearly with the relative magnitudes of their nuclei, as indicated by ob-
servation ; and hence the confirmation of Herschel's theory is complete.
If thb comparative view of comets be verified by more extended obser-
vations, it will serve to give some insight into the origin and arrange-
mient of these bodies, and inform us of the true place which they occu-
py in the planetary system. Nor will it be the least important reeah
of the establishment of this theory, that it will enable astronomers to
arrange comets according to the various stages of maturity at which, in

the progreaB of coasolidation, they have arriTed. Obserration has, in
tact, already forniebed na with an eitensiTe scale of comets, which are
: diatinguisbable by meaiiB of this important criterion. Several have been
seen which had no nucleus at all, presenting ooly a gradnal thickening
towards the middle parts, which were neariy translucent; while, on the
other hand, there are many whose condensation has proceeded so far,
by having been moTe subjected to the action of the solar heat, aa to
have a nucleus 100, 1000, or even 2000 miles in diameter. Those of
iha latter descrip^on approach, in alt the circumstances of their physical
diararter, to the nature of planetary bodies ; and particularly, like them,
are less exposed to those eadden chaogee from the violent action of the
sun's heat near their perihelion, which comets of a smaller size and a
looser texture are observed to undei^o.
" 111. From these observations, we shall be the better able to esti-
mate the probftbility of a aupposiuon, perhaps it may be said more spe-
culative than Qseful, but nevertheless founded on philosophical princi-
ples, whether or not comets be habitable bodies? It is very evident
that such a supposition can never apply to tbe generality of comets ;
for, with regard to those whose consolidation is stilt only partial, the
violent changes wbich take place in their constitution and structure,
both at the perihelion and at the aphelion, are totally incompatible with
all OUT ideas of either animal or vegetable existence. Bat with respect
to those comets, whose advanced state of maturity renders the sun's
influence incapable of mBterislly affecting the sur&ce of the nucleus,
there seems to be no physical impossibility why many of them may not
be the abode of living creatures, as well as the Earth and the other pla-
nets of the system.
" Yet considering tbe extremes of distance from the sun, at which
the comets are placed in different parts of their eccentric orbits, it has
been concmved, that the prodi^ous variation* of heat and cold to which
dte inhabitants of a comet must be exposed, render the above supposi-
tion quite untenable. This, however, is on objection, wbich, though
applicable to all comets, whatever be their state of consolidation, is truly
more specious than substantial. Newton, indeed, calculated that the
great Comet of 1680, which passed within 150,000 miles of the sun's
aurftce, mnst have been heated to a temperature SOOO times greater
than red hot iron. Bnt the simple &ct, that the comet, even if its den-
sity had exceeded that of iron itself, was not instantly dissipated by the
violence of such a combustion, indicates some error in the data on which
thi* calculation is founded. Still, though it should be allowed that the
350 Mr Milne*s Prize Essay on ComeU.
heat is not m great as MnvtiHi was inclined to eetimate, it ma^ be sup*
posed that the variatiaiis of temperature to which a comet is sabiected,
are yet much too considerable for the esiateoce and abode of bang«i
powessing coDititntions at all aaalogoui to drose upon the Eardi. Bst
an application of the Uw« of dwDiical science to this aubject, denon*
atrstee that these extremes of be«t and cold m by no means so execs*
aive, as the mere alterations in the cmnet's distance from dw sut might
perfa^ lead ns to imagine.
" In the first place, it is well knoim, that, in the heating of bodies,
when the compresaion to which they are subjected remaina the same,
there ii a certain point, beyond which, whatever be the means employed,
their temperature can never be elevated. Water, for instance, nnder
the common atmoxpherical pressure, may be beated up as far as 212°
of Falirenheit; but all the heat which we employ in the endeavour to
raise this temperature higher, is only dissipated in the ensuing erapoia-
tion. In like manner, the substance constituting a comet must have a
certain point of its own, which, however near it may qtproach die nid,
its mean temperature can never exceed. The tail of the comet may be
expanded t« a prodigions length, tbe nebulous envelope may become
enlarged to an equal extent; even the materials on tbe surface of tbe
nncleoB, by volatilization, may pass into a gaseous or aerial form ; but
the planetary or solid body itself will experience no accession of heal
beyond that point of maximum temperature, which its own nature and
coBstitution detenu ine.
" In the second place, we may observe, that wlien, by any means,
tbe denuty of bodies ia made to i^aDge, by a process, whether of rare-
faction, on tbe one hand, or of condensauon, on the other, they are al<
ways found to undergo a corresponding diminntioD or increase of tem-
perature. When, therefore, in the approach of a comet to tbe sua, all
the parte of its nebulous envelope and tail, which in the remoter regions
of its course had been gathered close about the head, become expanded
and attenuated, a very hu^ proportion of the solar tieat, which would
otherwise have passed into the nucleus, and contributed to raise its tern-
pOTature to a certain point, is carried off by the envelope and tul, in
order Xo preserve an equilibrium among the several parts. Let us at-
tempt to form some estimate of the actual loss of temperature thus sus-
tained by tbe rarefaction. If we assume that tbe nebulous maUer
ia elevated about 30 times its former height, the diminution <^ dea-
sity, corresponding with the increase of volume, will amount to
(30)^, or 27,000; and employing the fiH-mula given in the Supple-
ment to ibe Encyclopedia Britannica, article ' Climate,' we have

BUatuned by the rarefaction above supposed, amounted to two-thirds of
thia qnantity ; so that the actual influence of tbe sun, in raising the tem-
perature of the comet, will undoubtedly be diminishei) in the same pro-
portion. In a corresponding manner, when the comet retires towards
its aphelion, where the heat of the sun becomes so much weakened on
account of the distance, the coudenSHtion of the nebulous matter form<
tng the tul and envelc^ serres not only to furnish the ifucteDS with
continual supplies ^m the heat acquired at the perihelion, but even to
render the warming influence of the solsr rays much more efficacious
than at a less remote part of the comet's orbit.
" It appears, tiien, that tbe variations of heat and cold, to which
comets are exposed in the oppoute points of their course, oie by no ■
means so great as to be incompatible with the supposition of their being
fit abodes far animated beings : and if we recollect the fiicility with
which our own bodies can adapt themselves to great and sudden ex-
tremes of temperature, as exempjilied by Tarious experiments, we may
even conjecture these beings to possess a constitution not very dissi-
milar to that of the human species. Individuals, we know, have often
dlowed themselves to be confiued for a considerable time in apartments
heated to 260° and 280° of Fahrenheit, without feeling much inconve-
nience; and though we cannot as easily ascertun the extent to wbich
, cold may be endured by the human frame, we know that it is frequent-
ly exposed, without any injurious effects, to an intensity for surpassing
what is necessary for the congelation of mercury '. In order, then, to
4)e capable of sustaining those variations of temperature to which a
comet may be subjected, it is not necessary that the constitution of its
supposed inhabitants should be very different from tbe constitntion of
the beings belonging to the Earth. And when we recollect that these
variattiHis proceed in a gradual manner, not by the rapid transitions

whicb we often experience on our own globe, Uie progreM from one
degree of temperature to anotber, as tfae comet jonnieyB onwaid in its
cam«e, may be little perceived by its inbabitanta.
% " It ia true tbat the atinospbere respired by these beings, wbile it ia
at one place a highly attenuated gaa, ia at another converted into a me-
dium extremely dense ; and therefore it may be difficult to ccncMve
how animation can be supported in theae 0[q»o8ite situations. But
when Halley was able to breathe freely in a diving-bell, in which the
compressed air was twelve times more dense than that on the tops of
EDOuntuns, — and when the lungs, with all the other bodily M-gans, can
so readily accommodate themselvee to the most variable and trying cir-
camstancea, we do perceive how it is 'possible for respiration to be
carried on, notwithstanding these chaoges in a comet's atmo^hece,
which, though undoubtedly extensive, yet take place in a slow, and
thwefbre hannleas, manner. Another objection has been started to the
existence of living beings on cometa, on account of the alternations of
light and darkness to which, in the opposite portions of theii orbit, they
ai« thought Xa be exposed. But 1 find it remariced by Bailly, that the
Comet of 1680, suppoiiog it at the aphelion to be 136 times more dis-
tant from t^e sun than the Earth, ought for this reason to receive five
times as much light from the sun as we do from the full moon ; and
when, we add to this the superior density of the comet's atmospbere at
this distant part of its orbit, tt is capable of obtaining a still greater
qnanuty of light by refraction *.
" These esptaaatioos, then, if they be deemed correct, make it ap-
pear that the several changes which are produced upon th«> cona^tution
of a comet, in coneeqaence of its varying distances from the sun, are
not incompatible with our ideas of Emimated existence, and go so ^ as
to render it not improbable, that the beings which inhabit cornels may
even possess bo«li]y frames resembling those of terrestrial beings. But
why, it may be asked, are we so solicitous to es^blisb this r^emblance
between ourselves and the inhabitants of a colnet, as if that were a
condition which alone could render their existence possible ? When
we survey the wide field of animal organization Which lies within the
scope of oiu own experience, from Man, the proud lord of creation, to
those tribes of zoopbytca which we place lowest in the scale, do we not
behold « contianal snccesuon of beings, as infinite in variety as in
extent P If, then, upon the surface of onr awa little planet, we behold

Or ike Use qflAgatures arid Bleeding in Casea of Poisoning:
J.N a memoir, read lately by Cr Vemi^ to the Frmch Aca-
demy of Sciences, od Certmn Methods of treating all Cases of
Foisraiing, the author commenced with mentioning the expeai-
mentB in which Magendie succeeded in completely su^Mnding
absorption in a dog, by producing an artitidal plethcmiTtiy

354 On the Use oflAgaiures and Bleeding
ing on this important fact, he made the following experiment. Af-
ter putting three grains of alcoholic extract of nux vomica upon a
wound made in the foot of a young dog, he applied a ligature
above the humero-cubital articulation of the wounded limb. He
then slowly injected, by the jugular vein, as much water as the
animal could bear, without suffering much. After this, he open-
ed the vein of the poisoned limb, below the l^ture, and, ta-
king away a few ounces of blood, injected them into the jugu-
lar vein of another dog. This dog died in convuMons at the
very moment of injection. The wound of the first dog, how-
ever, having been carefully cleaned, a litde blood was allowed'
to Sow, and the animal was put at liberty. It exhibited no-
^mptoms of poisoning, and eight days after was perfectly wdl,
when it was sacrificed for other experiments.
The result of this experiment is eanly accounted for. It be-
ing known that plethora stops absorption ; the blood which flow.
ed from the vein that was opened could alone be impregnated
with poison, for that vein and its afferents were the only vessels
that did not participate in the general plethora.
This experiment appeared decisive to M. Vemi^re. But the
means of applying the principle which it affords to practice pre-
sents a great inconvenience, — the necessity of infusing water in-
to the veins. This infu^on, the author thinks, may be avoid-
ed, and that it is sufficient to induce a local plethora.in the p(n-
soned limb. Now, nothing is more easy than this, as it may be
■ done by a moderately tight ligature. This ligature applied, it
would be sufficient to open one of the veins of the engorged
part, to determine the flow of the poisoned blood.
The author adduced two experiments in support of Uiis me-
thod. In the first, three grains of extract of nux vomica were
spread upon a wound made on the cheek of a small-sized Aog.
After an application of six minutes, during which the experi-
menter kept the two jugular v^na compressed with his thumbs,
that of the poiscmed side was largely opened with a lancet, the
-blood Bowed abundantly, and the animal, when restored to its
feet, experienced only a little weakness.
In the other expoiment, the author inserted under the skin of
he BDtenor surface of the fore-1^ of a young dog, three gruns

of the SAme extract. A tight ligature was, at the same time,
applied to the limb. Five minutes ai^r the application, the
poison was removed by repeated washings ; the ligature was re-
moved, and the animal, being let loose, walked peaceably about.
It was, however, soon seized with very violent convulsions. A
laige qUanuty of blood was immediately taken from the jugular
vein, and the convulsions ceased. The animal, on being set at
liberty, walked as before ; only a few rattling inspirations were
heard from time to time, which presently ceased. The author
thought that, in this experimait, the ligature having been too
tight, the artery bad been compressed along with the vein, so
that plethora could not have been produced. ,
From this e.xperiment M. Verniere concludes, \8t. The inu-
tility of too tight a ligature ; ^icUy, That, even after the poison
has penetrated far into the torrent of the drculation, the evil is
not beyond the resources of art, and that it is still posable, by
means of large general bleedings, to expel the pcusrai from the
system.
It may, in fact, be easily conceived, and experiment proves
it, that if bleeding is practised at an early period, when the poi-
son is still contained in the large veins, the lungs, and the heart,
it will pass, by preference, through the path where it finds less
resistance ; and consequently, the portion destined for the other
organs must be diminished in the proportion of the blood that
passes through the veins opened.
Hitherto the treatment of al) cases of poisoning has been al-
most exclusively confined to removing the poison frbtn the surface
where it was deposited. No person ever dreamed of pursuing
it into the veins, and still less of arresting it in the depths of the
circulation. The experiments mentioned, reduce the treatment
of all cases of poisoning, hydrophobia included, to a few pre-
cepts, so simple and so easily executed, that the most ordinary
practitioner cannot fiul to apprehend it.

A HE observations, of which it is my object to give a summary
in the following pages, have all been made witli a simple mi-
croscope, and indeed with one and the same lens, the focal
length of which is about ,'gd of an incht.
The examination of the unimpregnated vegetable ovulum,
an account of which was pubUshed early in 182(i J, led me to
attend more minutely than 1 liad done before to the structure
of the pollen, and to inquire into its mode of action on the pis-
tillum in phtenogamous plants
In the essay referred to, it was shown that the apex of the
nucleus of the ovulum, the point which is universally the seat of
t|ic future embryo, was very generally brought into contact
with the terminations of the probable channels of fecundation ;
these b«ng either the surface of the placenta, the extremity of
the descending processes of the style, or more rarely, a part of
the surface of the umbilical cord. It also appeared, however,
from some of the facts noticed in the same essay, that there

Dollond, who obligingly made for me a simple pocket microscope, having
very delicate adjustment, and furnished with excellent lenses, two of which
are of much higher power than that above mentioned. To these I have often
had Tecourae, and with great advantage, in Investigating several minute points.
But to give greater GDnslttmcy to my atatements, and to bring the autgject as
much as possible wltbin the reach of geueial observatian, I continued to em-
ploy throughout the whole of the inquiry the same lens with which it was
commenced.

were cases in which the particles cantaiaed in the grains of pd.
len could hardly be conveyed to that pinnt of the ovulum
through the vessels or cellular tissue of the ovarium ; and the
knowledge of these cases, as well as of the structure aod eco-
nomy of the anthene .in AscIepiadeK, hod led me to doubt the
correctness of observations made by Stiles and Gl^cheo upwards
<!f mty years ago, as well as of some very recent stat^nents, re-
specting the mode of action of the pollen in the process of im-
pregnation.
It was not until late in the autumn of 1826 that I could at-
tend to this subject ; and the season was too far advanced to
enable me to pursue the investigation. Finding, however, in
one of the few plants then examined, the figure of the particles
- contained in the grains of pollen clearly discernible, and that
figure not spherical but oblong, I expected, with some c<mfi-
dence, to meet with [dants in other respects more favourable to
the inquiry, in which those particles, from peculiarity of form,
mi^t be traced through th«r whole course : and thus, per-
haps, the question determined whether they in any case reach
the apex of the ovulum, or whether their direct action is limit-
ed to other parts of the female organ.
My inquiry on this point was commenced in June 18^, and
the first plant examined proved in some respects remarkaWy
well adapted to the object in view.
This plant was Clarchia piddteUa, of which the grains of
pollen, taken from anthers full grown, hut before bursting, were
filled with particles or granules of unusually large size, varying
from nearly lo'ogth to about ^o'ijDth of an inch in length, and
of a iigure between cylindrical and oblong, perhaps slightly
flattened, and having rounded and equal extremities. While
examining the form of these parades immersed in water, I ob-
served many of them very evidently in motion ; their motion
connsting not only of a change of place in the fluid, manifested
by alteraUons in their relative portions, but also not unlre-
quently of a change of form in the particle itself ; a contraction
or curvature taking place repeatedly about the middle of one
side, accompanied by a ccHresponding swelUng or convexity on
the oppoOTte side of the particle. In a few instances the particle
was seen to turn on its longer axis. These motions were such
860 Mr Brown on the Exuteace of Active Malecviet
as to satisfy me, after frequently repeated observatioD, that tliey
arofie nather from currents in the fluid, nor from its gradual
evi^wratioo, but bekAged to the particle itself.
Grains of pollen of the same plant taken from anthers imme-
diately after bursUng, ccmtained siinilar subcylindrical particle^
in reduced numbers, however, and mixed with other particlea,
at least as numaxtua, of much smaller size, ^^nrratly spherical,
and in rapid osciUatory tnotiMi.
These smaller particles, or molecules, as I shall term them,
when first seen, I considered to be some of the cylindrical par-
ticles swimming vertically in the fluid. But frequent and care-
ful examination lessened my confidence in this suppoaiticD ;
and on continuing to observe them until the water had entirely
evaporated, both the cylindrical particles and spherical auAe-
cutes were found on the stage of the microscope.
In extending my observations to many other [dants of the
same natural family, namely Onagrarise, the same geaeral form
and similar motitxis of particles were ascertained to exist, espe-
dally in the various species of (Enothera, which I examined.
I fomid also in their gnuns of pollen taken from the anthers
immediately after bursting, a manifest reduction in the prapor-
tim of the cylindrical or oblong particles, and a ctKTesponding
increase in that of the molecules, in a less remarkable dc^rec^
however, than in Clarckia.
TiiK appearance, cm- rather the great increase in the number
of the molecules, and the reduction in that of the cylindrical
partides, before the groin of pollen could poe^bly have come in
contact with the sdgma, — were perplexing circiimstancea in this
stage of the inquiry, and rertainly not favourable to the suppo-
sition of the cylindrical particles acting directly on the ovulum ;
an opinion which I was inclined to adopt, when I first saw them
ID motion. These circumstances, however, induced me to mid-
tipiy my observations, and I accordingly examined numerous
species of many of the more important and remarkable families
of the two ^eat jH-imary divisions of ph«»K)gamous plants.
In all thete plants panicles were found, which in the diflerent
families or geaen varied in form frcnn obl<xig to spherical, ha-
ving manifest motions similar to those already .described ; ex-
cept that the change of Conn in the oval and oblong f)articles was

generally lew obvious than in Onagraiue, and in the spherical
particle was in no degree observable*. In a great proportion
of these ^iaats I also remarked the same reduction of the larger
particles, and a corresponding increase of the molecules after
the hurating of tbe anthene ; the molecule, of apparently ubi-
tona size and form, being then always present ; and in some
caaes indeed, no other particles were ol»erved, eklher in this or
in any early stage of the secreting oi^an.
In many plants belonging to several difierent families, but
especially to Graminese, the membrane of the grain of pollen is
ao transparent, that the motum of the larger particles within the
entire grain was distinctly viable ; and it was manifest also at
the more transparent angles, and in some cases even in the body
of the grain in Onagrarise.
In Asclepiadeas, strictly so called, the mass of pollen filling
each celt of the anthera is in no stage separable into distinct
gnuds ; but within, its tesselated or cellular membrane is filled
wi^ spherical panicles, commonly of two sizes. Both these kinds
of particles, when immersed in water, ore generally seen in vivid
motian ; but the apparent motions of the larger particle cught
. in these cases periiaps be caused by the rapid oscillauon of the
more numerous molecules. The mass of pollen in this tribe <^
plants never bursts, but merely connects itsdf by a determinate
pmnt, which is not unfrequently semitransparent, to a process
of nearly nmilar consistence, derived from the gland of the cor-
responding angle of the stigma.
In Periploceas, and in a few Apocinete, the pollen, which in
these plants is separable into compound grains filled with sphe-
rical moving particles, is applied to processes of the sljgma, ana-
logous to those of AsclefHadese. A similar economy exists
in Orchidese, in which the pollen masses are always, at least in
the early stage, granular ; the grains, whether simple or com-
pound, contfuning minute, nearly spherical particles, but the
whole mass being, with a very few exceptions, connecled by a

detenninate point of its surface with the stigma or glandular
process of that org;an.
Having found motion in the particles of the pdllea of all the
liTing plants which I had examined, I was led next to inquire
whether this property continued after the dteth of the plant,
and for what length of time it was retained.
In plants, either dried or immersed in spirit for a few days
only, the particles of pollen of both kinds were found in motion
equally evident with that observed in the living plant ; ^>eci-
mens of several plants, some of which had been dried and pre-
served in an h^barium for upwards of twenty years, and
others not less than a century, still exhibited the molecules or
smaller spherical partJdes in considerable numbers, and in evi-
dent motion, along with a few of the larger particles, whose
motions were much less manifest, and in some cases not olraerv-
able*.
In this stage of the investigation, having found, as I be-
lieved, a peculiar character in the motions of the particles of
pollen in water, it occurred to me to appeal to this peculiarity
as a test in certain families of Cryptogamoua plants, namely.
Mosses, and the genus Equisetum, in which the existence of
sexual organs had not been universally admitted.
In the supposed stamina of both these families, namely, in
the cylindrical antha*se or pollen of Mosses, and on the surface
of the four spathulate bodies surrounding the naked ovulum, as
it may be considered, of Equisetum, I found minute spheric^
particles, a]^)arently of the same size with the molecule de-
scribed in Onagrarise, and having equally vivid motion on im-
mersion in water; and this motion was still observable in speci-
mens both of Mosses and of Equiseta, which had been dried
upwards of one hundred years.
* While this sheet was paFsing throu^ the press, I luiTe examined tiie
pollen of Beveml flowers which bare been immersed in weak sjdiit alMnit ele-
veit months, particularly of fiala tricolor, ZimnJa aqmitiea, and Zea Mayi ,■
and in all these plants the peculiar particles of the pollen, which are oval or
short oblong, thou^ somewhat reduced in number, retain their form perfect-
ly, and exhibit evident motion, though, I think, not »> vivid us in those be-
longing to the living plitnt. In Viola Mcofor, in which, as well as in other
species of the same natural section of the genua, the pollen has a very re-
marlcabte form, the grun nn immersion in nitric acid still discharged its con-
tents bj its fbuT angles, though with less force than in the recent plant.

The very uoexpected fact of seeming vitality rettuned by
these minute particles so long after the death of the plant,
vouJd not perhaps have materially lessened my confidence in
the supposed peculiarity. But I at the same time observed,
that, on bruising the ovula or seeds of Equisetum, which at
first happened accidentally, I so greatly increased the number
of moving particles, that the source of the added quantity could
not be doubted. I found also, that, on bruiang first the floral
leaves of Mosses, and then all other parts of those plants that I
readily obtained similar particles, not in equal quantity indeed,
but equally in motion. My supposed test of the male organ
was therefore necessarily abandoned.
Reflecting on all the facts vith which I had now become ac-
quainted, I was disposed to believe that the minute spherical
particles or molecules of apparently uniform size, first se^i in
the advanced state of the pollen of Onagrarioi, and most other
Phsenogamous plants, — then in the antherse of Mosses, and on
the surface of the bodies regarded as the stamina of Equise-
tum, — and, lastly, in bruised portions of other parts of the
same plants, were in reality the supposed constituent or ele-
mentary molecules of organic bodies, first so considered by
Bufibn and Needham, then by Wrisberg with greater preci-
sion, soon after and sdll more particularly by MOller, and,
vCTy recendy, by Dr Milne Edwards, who has revived the
doctrine, and supported it with much interesting detail. I
now, therefore, expected to find these molecules in all organic
bodies; and, accordingly, on examining the various animal and
vegetable tissues, whether living or dead, they were always
found to exist; and merely by brui^ng these substances in wa-
ter, I never fuled to disengage the molecules in suffident num-
bers to ascertun their apparent identity in dze, form, and nto-
tion, with the smaller particles of the griuns of pollen.
I examined also various products of organic bodies, particu-
larly the gum resins, and substances of vegetable origin, ex-
tending my inquiry even to pit-coal; and in all these bodies
molecules were found in abundance. I remark here also, part-
ly as a caution to those who may hereafter engage in the same
inquiry, that the dust or soot deponted on all bodies in such

quantity, e^ietnally in London, is entirely oompoeed <^ these
molecules.
One of llie substances examined, was a Bpedmen of fossil
wood, found in Wiltdiire odite, in a state to bum witb flame ;
and as I fouttd these molecules abundantly, and in xdoUihi in
this qwdmen, I supposed that th^ existence, though in smaller
quantity, might be ascertained in nuaendized ve^table remains.
With this view a minute portion of silkified wood, which ex-
hibited the structure ot Conifers, was bruised, and spherical
particles, or molecules in all respects like those so frequently
mentioned, were readily obtained from it ; in such quanti^,
however, that the whole substance of the petrifaction seemed U>
be formed of tbem. But hence I inferred that these molecules
were not limited to organic bodies, nor even to thdr products.
To establish the correctness of the inference, and to asoertun
to what extent tiie molecules eusted in mineral bodies, became
the next obje<4 of inquiry. The first substance examined was
a minute fragment of mndow-f^lass, from which, when m»riy
bruised on the stage of the microscope, I readily and cc^ously
obtained molecules ^re^ng in size, form, and motion with those
which I had already seen.
I then proceeded to examine, and with similar results, such
Hunerals as I either had at hand or could .readily obtwi, inclu-
ding several of the simple earths and metals, with many of thar
combinations.
Rocks of all ages, including tiioee in which organic rem^s ,
have never been found, yielded the molecules in abundance.
Their existence was ascertained in each of the constituent mi-
nerals of granite, a fragment of the Splunx bdng one of the ^le^
cimens examined.
To mention all the mineral substances iu which I have found
these molecules, would be tedious ; and I ^all confine myself
in this summary to an enumeration of a few of the most re-
markable. These were both of aqueous and igneous origin,
as travertine, stalactites, lava, obsidian, pumice, volcanic ashes,
and meteorites from various localities*. - Of metals I may
mention manganese, nickel, plumbago, bismuth, antimony, and
' I fa&ve rince found the molecules in the und-tubM, fiamed b^ U^ttiiD);,

anenic. In a word, in every mineral which I could reduce to
a powder, sufBdently fine tobe tempwarily suspended in water,
I found these molecules more or less copiously ; and in some
cases, more particularly in silidous crystals, the whole body
submitted to examinaticm appeared to be composed of them.
In many of the substances examiDed, especially those of a
fibrous structure, as asbestos, actinolite, tremolite, zeolite, and
evfQ steatite, along with the spherical molecules, other ,corpuscu les
were found, like short fibres somewhat monilifcHin, whose trans-
rerse diameter appeared not to exceed that of the molecule of
which they seemed to be primary comlnnations. These fibrils,
when of such length as to be probably composed of not more
than four or fire molecules, and still more evidently when formed
of two or three only, were gaierally in motion, at least as vivid
as that of the simple molecule itself; and which from the fibril
oflen changing its portion in the fluid, and from its occasional
bending, might be sud to be somewhat vermicular.
In other bodies whidi did not exhibit these fibrils, oval par-
ticles of a fflze about equal to two molecules, and which were ,
also conjectured to be primary comlnnations of these, were not
unfrequeoUy met with, and in motion generally more vivid
than that of the nmple mcdecule ; their motion consisting in
turning usually on their longer axis, and then often appearing
to be flattened. Such oval particles were found to be nume*
rous and extremely active in white arsenic.
As mineral bocties which had been fused contained the movii^
molecules as abundantly as those of alluvial deposits, I was de-
nrous of aacertaining i^ether the mobility vi the particles ex-
istit^ in orgamc bodies was in any degree aflected by the ap-
plication of intense beat to the containing substance. With
this view small portions of wood, both living and dead, linen,
pi^r, cotton, wool, mlk, hair, andmuscular fibres, were exposed
to the flame of a candle, or burned in platina forceps, heated by
the blow[npe ; and in all these bodies so heated, quenched in
mter, and immediately submitted to examination, the molecules
were Jbund, and in as evident motion as those obtained from tbe
same substances before burning.
In srane of the v^etable bodies bunted in this manner, in
addition to the simple molecules, primary comUnatiofls of these
366 Mr Brown on the Existence ^Active Mdtadea
were observed, consistiDg of fibrils having transversa coUtrac-
tioDs, corre^Koding in number, as I omjectured, with that of
the molecules componng them ; and Uiose filnils, when not con-
sistiDg cJ a greater number than four or five molecules, exhibit-
ed motion, resembling in kind and vivadty that of the mineral
fibrils already described, while longer fibrils of the same appa-
rent diameter were at rest.
The substance found to yield these active fibnls in the largest
proportion and in the most vivid motion, was the mucous coat
interposed between the skin and muscles of the haddock, espe-
cially after coagulation by heat.
The fine powder produced on the under surface of the fronds
of several ferns, particularly of AchroHichum cahmekmos, and
the spe<nes nearly related to it, was found to be entirely com-
posed of simple molecules, and their primary fibre-like com-
pounds, both of them being evidendy in motion.
There are three points of great importance which I was an-
xious to ascertain respecting these molecules, namely, tbeir form,
whether they are of uniform size, and.th^r absolute magnitude.
I am not, however, entirely satisfied with what I have been able
to determine on any of these points.
As to form, I have stated the molecule to be spherical, and
this I have done with some confidence ; the apparent exceptions
which occurred admitting, as it seems to me, of being explained
by supposing such particles to be compounds. This supposition
in some of the cases is indeed hardly reconcileable with their ap-
parent size, and requires for its support the further admis^on,
that, in combination, the figuie of the molecule may be altered.
In the particles formeriy considered as pnmary combinations of
molecules, a cectain change of form must also be allowed ; and
even the simple molecule itself has sometimes a}q)eared to me
when in motion to have been slighdy modified in this respect
My manner of estimating the absolute magnitude and unifor-
mity in size of the molecules, found in the various bodies sub*
mitted to examination, was by placing them on a micrtMneter di-
vided to five-thousandths of on indt, the lines of which were
VOTy distinct ; or more rarely on one divided to ten thousandliifi,
with fainter lines, not readily viable without the application of
plumbago, as employed by Dr Wollaston, but which in my sub-
ject was inadmissible.
in Organic and Inorganic Bodkg. 367
The results so obtuned can only be regarded as approxima-
tions, OD which perhaps, for an obvious reason, much reliance
will not be placed. From the number and degree of accord-
ance of my observations, however, I am upon the whole dispos-
ed to believe the cdmple molecide to be of uniform size, though,
as exisdng in various substances and examined in circumstances
more or less favourable, it is necessary to state that ita diameter
appeared to vary from ttiocc^^ ^ BBiinot^ of an inch *.
I shall not at present enter into additional details, nor shall
I hazard any. conjectures whatever respecting these molecules,
whi(^ appear to be of such general existence in inorganic as
well as in organic bodies ; and it is only farther necessary to
mention the principal substances from which I have not been
able to obtain them. These are oil, rean, wax, and sulphur,
such of the metals as I could not reduce to that minut« state of
divisiim necessary for their separation, and 6nB]ly, bodies so-
luble in water.
In returning to the subject with which my investigation com-
menced, and which was indeed the only object I originally
had itv view, I had still to examine into the probable mode of
action of the' Urger or peculiar particles of the pollen, which,
though in many cases diminished in number before the grain
could possibly have been applied to the stigma, and particularly
in Clarckia, the plant first examined, were yet in many other
plants found in less diminished proportion, and might in nearly
all eases be supposed to exist in sufficient quantity to form tho
essaitial agents in the process of fecundation.
I was now therefore to inquire, whether their action was con-
fined to the exteriial organ, or whether it were possible to follow
theni to the nucleus of the ovulum itself. My endeavours, how-
ever, to trace them trough the tissue of the style in plants well
suited for this investigation, both from the ^ze and form of the
particles, and the development of the female parts, particularly
Onagrarise, was not attended with success ; uid natha- in this

368 Mr Brown on the Existence of Active Moltctdet
nor in any other tribe exatnined, have I ever been able to find
them in any part of the female oi^an, except the stigma. Eren
in ibose families in which I have supposed the ovulum to be
naked, namely, Cjcadete and Conifers, I am inclined to think
that the direct action of these partides, or of the pollen contain-
ing them, is exerted ratfaer on the orifice of the proper mem-
brane than cm the apex of the included nucleus -, an opinion
which is in part founded on the partial withering confined to one
«de of the orifice of that membrane in the larch,— an appearance
which I have remarked for several years.
To observers not aware of the existence of the elementary
active molecules, so easily separated by pressure from all y^e-
table tissues, and which are diaaigaged and become more or less
manifest in the incipient decay of eemitransparent parts, it would
not be difficult to trace granules through the whole length of the
style: and as these granules are not always visible in the early
and entire state of the organ, they would naturally be supposed
■ to be derived from the pollen, in those cases at least in which
its contuned particles are not remarkably different in ^ze and
form from the molecule.
It is necessary also to observe, that in many, perhaps I might
say in most plants, in addition to the molecules separable from
the stigma and style before the application of the pollen, other
granules of greater size are obtmned by pressure, which in some
cases closely resemble the particles of the pollen in the same
plants, and in a few cases even exceed them in «ze : these par-
ticles may be conndered as primary combinations of the mol&-
cules, analogous to those already noticed in mineral bodies and
in various organic tissues.
From the account fbrmetly ^ven of Ascle[nades, Ferlplqces,
and Orcbideie, and particularly from what was observed of As-
depiadese, it is difficult to imagine, in this family at least, that
there can be an actual transmisnon of particles from the mass of
pollen, which does not burst, through the process of the stigma;
and even in these processes I have never been able to ot»erve
them, though they are in general sufficiently transparent to show
the particles, were they present. But if this be a correct state-
ment of the structure of the sexual organs in Asclepiadeee, the
question respecting this family would no longer be, whether the
particles in the pollen were trwsmitted through the stigma and
in Organic and Inorganic Bodies. 369
style to the ovula, but rather whether even actual contact of
these particles with the sur&ce of the stigma were necesaary to
impr^nation.
Finally, it may be remarked, that those cases already adverted
to, in which the apex of the nucleus of the ovulum, the sup-
posed point of impregnation, is never brought into contact with
the probable channels of fecundation, are more unfavountUe to
the opinion of the transmis«on of the particles of the pcdlen to
the ovulumj than to that which considers the direct action of
these particles as confined to the external parts of the female
organ.
The observations, of which I have now given a brief account,
were made in the months of June, July, and August, 18S7-
Those relating merely to the form and motion of the peeuliar
pafticlesof the pollen were stated, and several of the injects,
shown, during these months, to many of my friends, parUculariy
to Messrs Bauer and Bicheno, Br Bostock, Dr Fitton, Mr E.
' Forster, Dr Henderson, Sir Everard Home, Captain Home, Dr
Horsfield, Mr Koenig, M. Lagasca, Mr Lindley, Dr Maton,
Mr Menzies, Dr Prout, Mr Renourd, Dr Roget, Mr Stt^es,
and Dr Wollaston ; and the general existence of the active mol^
cules in inorganic as well as organic bodies, their apparent inde-
structilnlity by heat ; and several of the facts respecting the
primary combinations of the molecules, were communicated to
Dr Wollaston and Mr Stokes in the last week of August
None of these gentlemen are here appealed to for the correct-
ness of any of the statements made ; my sole object in citing
them being to prove from the period and general extent of the
commmii cation, that my observations were made within the dates
g^ven in the title of the present summary.
The facts ascertiuned respecting the motion of the particles of
the pollen, were never considered by me as wholly original ;
this motion having, as I knew, been obscurely seen by Need-
ham, and distinctly by Gleichcn, who not only observed the mo-
tion of the particles in water after the bursting of the pollen,
but in several cases remarked their change of place within the
entire grain. He has not, however, given any satisfactory ac-
count either of the forms or of the motions of these particles,
and in some cases appears to have confounded them widi the
elementary molecule, whose existence he was not aware of.
JULY — SEPTEMBER 1828, A a
Ei70 Mr Brown on t/ie Existence ^JcHve Molecuks
Before I engaged in the inquiry in 18S7, 1 was acqutunted only
with the abstract gven by M. AdcJphe Brongniart himeelf, of
a very elaborate and valuable memoir, entitled " Mecherche*
stir la Ghiiralion et le Devehppement de VEmbryon dans Ut
VigOaua: Phanerogames,'" which he bad then read before the
Acad^ny of Sciences of Paris, and has since published in the
Jinnales des Sciences Naturelles.
Neither in the abstract referred to, nor in the body of the
meoioir, which M. Brongniart has, with great candour, given in
its ori^nal slate, are there any observations, appearing of im-
portance even to the author himself, on the motion or form of
the particles ; and the attempt to trace these particles to the
ovulum with so imperfect a knowledge of their dtstingiiishing
characters, could hardly be expected to prove satisfactory. Late
in the autumn of 18^, however, M. Brongniart having atrhis
command a microsci^ constructed by Amici, the celebrated Pro-
fessor of Modcna, he was enabled to ascertMn many important
facts OD both these points, the result of which he has given in
the notes annexed to his memoir. On the general accuracy of
his observations on the motions, form, and size of the granules,
a» he terms the particles, I place great reliance. But, in at-
tempting to trace these particles through thdr whole course, he
has overlooked two points of the greatest importance in the in-
vestigatJon.
For, in the first place, he was evidently unacquunted with
the fact, that the active spherical molecules generally exbt in
the grain of pollen along with its proper particles ; nor does it
af^ar from any part of his memoir that he was aware of the
existence of molecules haying spontaneous or inherent motitni,
and distinct from the peculiar particles of the pollen, though he
has doubtless seen them, and in some cases, as it seems to me,
described them as those particles.
Secondl^f He has been Batis6ed with the external appearance
of the parte in coming to his conclusion, that no particles capa-
ble of motion exist in the style or stigma before impr^piation.
That both umple molecules and larger particles of different
f<»in, and equally capable of motion, do exist in these parts, be-
fore the ^iplicalion of the pollen to tbe stigma can possibly take
place, in mai^ of the plants submitted by him to examination,
may easily be ascertained; particularly in Antirrhmum mfffia.
in Organic and Inorganic Bodies. 371
of which he has ^ven a figure in a more advanced state, repre-
senting these molecules or particles, which he supposes to have
been derived from the grains of pollen, adhering to the stig-
ma.
There are some other points respecting the grains of pollen
and their contained particles, in which I also differ from M.
■ Brongniart, namely, in his supposition that the particles are not
formed in the grain itself, but in the cavity of the anthera; in
his assertion respecting the presence of pores on the surface of
the grain in its early state through which the particles formed
in the anthera, pass into its cavity ; and, lastly, on the existence
of a membrane forming the coat of his boyau or mass of cylin-
drical form ejected from the grain of pollen.
I reserve, however, my observations on these and several
other topics connected with the subject of ihe present inquiry,
for the more detailed account which it is my intention to give.

The phenomenon regarding the action of the seed of the next species with
water is very beautiful here also. When the dry seed ia thrown on the
surface of water, it for a time only partly sinks, and the vessels being
liberated on the lower half oUly, it seems to float on a cushion of cotton.
The pubescence every where upon the plant is glandular, and ia parti-
cularly abundant and glutinous on the calyx.
This is a, very pretty plimt, and being cultivated with the greatest ease,

annuals. The seeds were collected by Mr Douglas on the NW. coast
of America, and were presented to us by Mr Sabine. The plants

had not acquired Its characteristic habit. There seems nearly as little
doubt of the identity of the plant figured by Dilleuius ; but the de-

This plant was introduced into the collection of Mr Cunninghame at
Comely Bank, near Edinbur^, in 1^6, by Mr Blair, who Ibund it grow-
ing in Upper Canada. It bears cultivation well, has been kept by Mr
Cunnin^ame in pots with peat soil, in the stove, and flowered very
abundantly in June IB3S. It flowered in the open air at the Boyal Bo-
tanic Oarden in the same month. We owe the plant to the Countess
of Dalhousie, who introduced it from Canada. Dr Barton appears first
to have discovered the species in rich soil, under damp shady woods,
along the banks of the Schuylkill, near Philadelphia, in 181.1. It has
probably, therefore, a pretty wide range in North America, though not
mentioned by any American botanist except the two I have quoted.
Its period of flowering in Pennsylvania is precisely the same (June) as
in cultivation with ug, either in the stove, or expoaed to the open air-
It has neither size nor cdour to make it attractive.
The great resemblance between this plant and Ltporis Lotteln of Kurope,
caused them to be considered the same in America, but Or Barton very
properly points out the distinction in the tiiaooular stem of L. LoeieSi,
and the different direction of the perianth i ana I may add, that depend-
ing on the lip being entire, and longer than the perianth in the Euro-
pean species. The comparative length of the scape and leaves varies go
much that it deserves no attention. /?

serrato-incised, elliptico-lanceolate. Fhmers corymbMe, small. Co/gu
subhispid, concave, nearly as long as the corolla. Pelalt yellow, entire,
limb rounded, equiil in length to the ckw. Filammta slender, rather
longer than the calyx ; anthers small. SHgma large, its lobes diverting.
Style distinct, though short SUigtiei in racemes, longer than the peiU-

Seedi oblong, brown, about 14 in each siliciue. Whole plant to the base
of the Biliiiues of a glaucous appearance, from a close, dense, short, salt
tomentum. Lower part of the stem purple.
The plant was raised at the Aoyal Botanic Garden iron the same collec-
tion of seeds, and under the same treatment, a.i the last species. It pro-
duced its flowers in Uay. The seeds were only marked with the gene-
ric name by Dr Richardson, but the species seems the same with thaf
given by him to Protessor Jameson under the name I have adopted. I
cannot, however, persuade myself that it is the same with the plant of
Nuttall, or De CandoUe. The diiferent comparative length of the pe-
dicels and siliques, which never varies in our specimens, and other
marks, seem to keep them distinct, r"

We received the seeds of this unusually beautifril umbelliferous plant from
Mr Froser, colonial botanist. New South Wales, in November I8S7, un-
der the generic name firunooia. Thej were marked " native of tiie
Island olBaTBcha."
The plants were raised in a cold frame, and have been in fiower In the Bo-
tanic Garden during August. Tbeyappear to belong to the genua TVs- .
Aymen$ of Rudge, hut the root-teaves at the specie* figured by him are
more divided, and on much longer petioles than in any of our spedmens ;
his plant is much smaller, the rays of the umbel much shorter, the pe-
tals (^ a verr different shape, and shorter than the stamens, and, above
all, the fruit Is said to be sut^lobular, instead of fiat, as with us. Yet
the habit is so much alike, that a fear of multiplying names, without a
certainty of a difference of Epedes, had led me tu adopt his specific name
with doubt, while 1 at the same time pointed out the above distinctions,
and thou^t it difficult to supixiBe that su verv beautiful a flower should
have been so long overlooked, if it grows, as he statea his to have done,
near Fort Jackson. On showing the proof-Hheet, however, to JvT. Al-
phonse De Condole, I was informed by him, that Us &ther conmdeis It
certainly distinct, and will call it T. earvlea. Such authority confirmed
my own doubts, and I willingly adopted this designation. I have since
heard from Dr Hooker that he too itupecU Rudge's plant may be dis-

I have considerable doubt about t^e correctness of the specific name and
the synonyms quoted; but not at present having an opportunity of con-
suiting Venteoat, I think it right lo adopt bis nauie till I have. The
genus Vitlania is probably naturally distmci from MenyanOia, but this
species shows that the essential generic character requires revision./^
Note In the last Number of this Journal, I described, under tbe name
of CatUeya intermedia, a beautiAll plant which flowered at the Botanic Garden,
and an admirable and most correct figure of the specimen has appeared under
the same name in the Botanical Magazine, t. 2SS1., the thin, grey,, membrs'
nous sheath of the stem only having been neglected in the colouring. I
pointed out its near affinity to C. Forbem (BoL Keg. t. 953.), but considered
it certainly distinct, especially on account of the very diflerent appearance of
the spathe. Subsequently, however, I began to doubt whether I was right,
ibr a apedmen flowered with ua having the colour, and in some other re-
spects the appearance, of C ForhetH, stlU, however, retaining the spathe of
C. inMrnudiii. Within these few days, I have seen In the possession of Mr
Neill a specimen of C. Forlieni from ue Chiswick Garden. It has the spathe
of our plant ; and as I consider it authority for ascertaining the species of Mr
Ijndley's, I must believe the figure m Botanical Regiater faulty, or the plant
liable to great variation, and therefore I take the eorUest opportunity to state
my belief, that ours is only a beautiful variety of the same.
Tbe original specimen has again flowered with us. It retained all its
splendid colouring, and produced two floweiG, with one or more abortive buds,
BO that probably ft may yet assume a much more munificent appeaisnce. Is
there not some reason to fear, that, in Ihis splendia genus, forms vary very
considerably, and that this may nut be the only instance in which species aM
varieties have been confounded F /J

Mr Blackadder's communication on poW lights, illustrated
with drawings, was laid before the meeting.
Mr Bald, mining-engineer, read a memtur on the fires that
take place in collieries, and particuhtrly <m the recent fires in
the collieries of Whitehill and Polton, in Mid-Lothian, and of
South Sauchie, in Clackmananshire. (This important paper is
printed in this Journal, supra, p. 101, et seq.)
The Secretary read a notice communicated by Mr MacgilU-
vray, regarding a cuckoo, which had been kept in a cage rioce
it was taken from a btlark's nest, in the end of July 18S7; and
the Inrd was communicated to the meeting. (See supra, p.
200.)
Mr Falconab, Vice-President, having taken the chair. Pro-
fessor Jameson communicated a notice in regard to the opaline
wood found in New South Wales, and exhibited a magnificent

bane, Bart.
June 21. — David Falconak, Esq. Vice-Preudent, in the
chair. — At this meeting his Excellency Count Platen, vice-lieu-
tenant of Norway, and Professor S. Nillstxi, of the University
of Lund, were elected foreign members.
The Secretary read a paper by the Rev. William Scoresby of
Liverpool, entitled, Bemarks on the Probability of reaching the

SCIENTIFIC INTELLIGENCE.
NATURAL FHILOaOPHY.
1. Proposed Impravemmi of the Air-Pump. — There is rea-
son to think that something like Mr Watt's principle of the
double stroke in the BKam^engine, might be advantageously ap-
plied to the air-pump By this means one barrel could do the
work of two, which would both lessen the cost and greatly di-
minish friction. At first it might^be supposed that, by this ar-
rangement, the management of the valves would be rend»«d
rather complicated ; but, instead of that, they wduM admit of
considerate amplification, by ad<^ting another prinraple often
employed about steam-engines, under the name of the ooffer-
slide valve. Suppose the barrel to be provided with a solid pis-
ton, moved by a rod passing through an tur-tight collar. Let
there be two holes in the side of tiie barrel, one adjtnning each
Old; and let these be cova«d by a sliding bar furnished with
four holes on its ^de, two being near to each end, and the whole
so arranged, that two of them at a time, but taken in an alter-
nate order, can, by a slight motion of the bar, be brought oppo-
site the holes of the barrel, while the other two are not, and
vice versa. Suppose two of the four holes, say the middle ones,
to be the ends of two tubes which unite in one slender wind-
ing and slightly flexible tube, communicating with the receiver ;
and let the other two be merely perfm-ations, which may have
thrir extmor ends «ther quite open, or, to prevent any return
of air into the barrel, they might be covered with alipa of blad-
der or oiled silk. If, then, the bar be moved up and down alter-
nately about the third of an inch, so as to have two of its bides,
one of each sort, remaining over these in the barrel, while the
-piston moves in the one direction, and the other two renuuiHi^
over those of the barrel, while the {nston returns in the c^tpo^le
directiffli, it is evident that we shall have, in this ample arrange-
ment, all the security of four metallic valves, and a nngle barret
and piston dtnng the work of two. The obvious design of tfae
long fiexible tube is to permit the compound valve to more
without any other joints. It might, indeed, remain fixed, while-

Prognoses of ike Weather. — Red clouds in the west, at sun-
set, .especially when they have a tint of purple, portend fine
weather. The reason of which is, that the air, when dry, re-
fracts more red or heat-making rays ; and as dry air is not per-
fectly transparent, they are again reflected in the horizon. A
coppery or yellow sunset generally foretels r^n ; but as an in-
dication of wet weather approaching, nothing is more certain
than the halo around the moon, which is produced by the pre-
cipitated water ; and the larger the circle the nearer the clouds,
and consequendy the more ready to fall. The old proverb is
often correct :
A rainbow In the morning is the shepherd's warning ;
A rainbow at night U the shepherd's delight
A rainbow can only occur when the clouds, cont^ning or de-
poating the rain, are opposite to the sun ; and in the evening
the rainbow is in the east, and in the morning in the west ; and
as our heavy rains in this climate are usually brought 1^' the
westerly wind, a rainbow in the west indicates that the bad
weather ison the road, by the wind, to us ; whereas the rainbow
in the east proves that the rmn in these clouds is pas^g from
us. When the swallows fly high, fine weather is to be expected
or continued ; hut when they fly low, and close to the ground,
jaia is almost surely approaching*. This is explained as fol-
lows : Swallows pursue the flies and gnats, and ffies and gnats
usually delight in warm strata of air ; and as warm mr is lighter,
and usually moister, than cold wc, when the warm strata of our
air are high, there is less chance of racnsture b^ng thrown down
from them by the mixture with cold air ; but when the warm
and moist ^r is close to the surface, it is almost certain that, as
the cold air flows down into it, a deposition of water will take
place. When sea-gulls assemble on the Und, stormy and rainy

weather is almost always approaching * ; the reason of which
might he thought to be that these animals, sendhle of a curreot
of lur approaching from the oceani retire to tfae land to shelter
themsetyes fh>m the storm- This is not the case however. The
stOTm is thdr element ; and the little petrel enjoys the heaviest
gate, because, living on the smaller sea-insects, he is sure to
find his food in the spray of a heavy wave, and she may be seen
flitting above the edge of the highest surge. The reason of
this'roigratioD of gulls, and other sea-birds, to the land, is their
secunty of finding food ; and they may be observed, at this
time, feeding greedily on the earlh-wonns and larvse driven out
of the ground by severe floods ; and the fish, on which they
prey in fine weather mi the sea, leave the surface, and go deeper
, in storms. The search after food is the prindpal cause why
animals change their places. The difilerent tribes of the wading
birds always Tmigrate when rain is about to take place. The
vulture, upon the same principle, follows armies; and there i»
no doubt that the augury of the ancients was a good deal found-
ed upon the observation of the instincts of birds. There are
many superstitions of the vulgar owing to the same source. For
anglers, in spring, it is always unlucky to see single mag-
[nes, but two may be always regarded as a favourable omen ;
and the reason is, that, in cold and stormy weather, one magpie
alone leaves the nest in search of food, the other remuning sit.
ting upon the eggs or the young ones ; but if two go out tc^e>
tber, it is only when the weather is warm and mild, and favour-
able for fishing. — Sir H. Davy in Sahnonia.
3. Disturbance of the Magnetic Needle by Polar Li^ta. —
Various natural causes act upon the magnetic needle, so as to
occasion a sudden change in its portion, or at least to disturb
the regularity of its diurnal variations. Of all these causes, the
aurora boreahs appears to be the most energetic and infallible.
When this meteor rises ia the northern r^ons, the sky is re-
splendent with light ; and during its whole continuance, which
sometimes lasts for ten or twelve hours, the magnetic needle ex-
periences a continued agitation, and a considerable deviation.
The summit of the arch of the aurora is in general in the mag-

netic meridian, and its crown, that is to say, the focus toward
which the rays of fltune, which seem to proceed from the hori-
zon, or from the arch itself, dart, always occurB nesrly in the
prolongation of the indination of the needle. The compass is
not only agitated in the places where the aurora is vigibie, but
eJso at great distances, at Paris and Wiliia, for exaiBple, even
when there are no traces of the meteor to he perceived in the
sky. But, in genenil, the agitatitm is greater the nearer the
phenomenon is, and the greater intensity it displays. Thus
we are told that the compass of the Paris Observatory of-
ten experiences, in the day or in the night, a sudden deviation,
which occarionally extends to one degree, without any appa-
rent cause being discoveraUe ; and it is afterwards learned that
the compasses of London and Petersburgh have at the same
time experienced similar motions, and that in the northern
countries some briUiant aurora has been observed. An observer
in his cabinet, says Pouiilet, is therefore appized by his com-
pass, of what is taking place in the polar ic^^ns, just as he
learns, from his barometer, what is taking place in the higher
r^OQS of the atmosphere.
4. Effects o/" Ranged Air of Mountains on the Puiae. — Dr
Brunner of Berne, read last year to the Helvetic Society of
Natural Sciences, the second part of the account of his journey to
Etna, in the year 18S6, in which, after describing the mountain,
and speaking of its volcanic phenomena, he entered into minute
detfuls respecting the limits of the «iow upon it, the circum-
stances of which he did not well know bow to explain. He then
spoke particularly of the phenomenon of the acceleration of the
pulse, and of the changes in the beatings of the pulse, {n^uced
by ascending hi^ mountains. He mentioned the more remark-
able examples of the two phewmiena, and related what he had oc-
casion to observe himself with reelect to them. He did not him-
self suffer at the summit, which is 10,1 5S feet above the sea,
and in an extremely rarefied lur. At the edge of the sea his
pulse beat from 6S to 6S times in the minute ; at Nicolod, si-

5. Meteor (fa Green Co&mr.— On the night of the 11th of
February \%StS, between eleven and twelve o'clock, as I was
crossing the East River, between this city and Long Island, X
observed a beautiful meteor, which was viable Ew about the
space of two seconds. Its course was from a point perhaps ff*
below the zenith, toward the horizon in a N.E. direction. It
described an arc of perhaps S0°, when it apparently exploded,
without any report that I could hear. Its colour was a singu-
larly pure graaa green, of a light shade ; the tail which it left
was of the same colour, and so were the scintillations which ac-
companied its apparent explosion. The latter were distinct,
like those accompanying the bursting of a rocket, but by no
means ao numerous. Two gentlemen who were in the boat
with me at the time also saw it. — SUliman's Joumtdy vol. xiv.

6. On Tkermo-Barometrical Ottservations. — M. HOTtier pre-
sented last year, to the Helvetic Society of Natural Science, the
results of observations made in January ISST, by M. Escb-
mann of Zurich, during an abode of fourteen days on the sum-
mit of Rigi, 5530 feet above the level of the sea, for the im-
provement of thermo-baFometncal observations. There results,
irom a hundred and twenty observations made every bour, from
seven in the morning to nine in the evening, and ctnnpared with
simultaneous observatJcms made at Zurich, that the height of
Ri^ above Zurich (which is 708 toise«), is without any doubt
ten toises greater by- the observations made at noon, than by
those made in the mtnuing or evening. This resiilts still more
evidently &om a series of a hundred and eighty-«x observattona
made in June of the same year, only the Utter give two toises
more for the height. It appears that this augmentation of
h^g^t, from one hour to another, is connected with the increase
of temperature. The evening heights, however^ diminish even
when the heat still increases. The maximum of hei^t cran-
tndes pretty well with noon. The summer obpervations give a
height about seven toises greater than those n>ade in winter. It
appe&rs from this that s difin'rait height may be obtained for
each seascHi and each hour of the day. The authw does oA
venture to o9er an (^nnioo respectii^ the causes of this ancmaly,
but he thiuks that there is wanting a Beries <^ such obaerviubna,

in a vertical direction, is exactly 9T tinses fw 1 degree of Reau-
mur, by the summer observations. The winter observations are
of no use in this respect, on account of the southerly winds
which prevail at these heights at that season. The daily oscil-
laticne of t^e barcuneter whieh, according to fourteen observa-
tions made duly at Zurich, appear very r^ular, cease entirely

8. Chemical Reeearckes respecting the Mineral Waters of
Geilnau, Fachingen, and SeUera. By G, Bischof 8vo. Bonn,
1826.— Professor Bischof ''s interesting work on springs, entitled
" Cbemische Untersuchungen," &c. contains much curious and
valuable inform'atiMi. The first chapter contmns the analysis
of three springs, and the second their geognostical relations.
They issue Irom clayaUte, and are in the vicinity of dolomites
and igneous rocks. In the third chapter, the author treats of
the rdation of the composition and temperature of the springs to
the surrounding rocks. The springs that are strongly impreg-
nated with carbonic add, imd contain soda, are connected with
the volcanic lines. They are scattered in seven volcanic groups,
from tiie Eiffel to the Riesengehirge. He enumerates these
groups, and connects with them the Pyrenees, Auvergne, and
the Vivarais. In- Switzerhind, on account of the absence of ba-
salt, there are none of these springs. The soda is fiimished by
the volcanic rocks. As all the springs contain more or less car-
S0St Scientific IrUdUgemx. — HydrogrofJty.
biHiic. scid, the author suppooes that this gas is gcneralty pro-
duced in the intoior of the earth, but this chemical process is
only more active in votcanic or volcanised places. Mtfriatic
add and sulpburic aad exist only in spring that are in the vi-
caatj of volcanoes in a state of activity. All the saliferous de-
posits are of volcanic origin. The fur, acting upcm the beds of
sulphur, produces sulphurous add and sulphuretted hydn^en.
Sulphuric add niay be ftwmed of sulphurous add or pyrites.
Muriatic acid is formed by the action of sulphuric add upon
salt The carbonic add circulating in all the volcanic rocks de-
composes the alkalies and salts, and impr^nates the springs
with them. The two other volcanic adds also act ; and thus is
explained the formation of mineral springs. In the fourth
chapter, the author con^ders the compoation of mineral waters,
the merit of tbdr analysis, and of thdr artificial recomposition,
ihdr imponderable parts, die existence of mutually decomposing
salts, &c. The following are the results of the imalyses of these
, springs.

petrifying qualities of the water of the river Irawaddy : I now saw
a strong proof of the rapidity with which it converts fordgn bo-
dies into stone. The pioneers were ordered to remove a house,
which would have interfered with the defence of the stockade, if
the enemy had assailed it. Upon endeavouring to cut down the
massive teak-pillars on which it was raised, they found that the
edges of thdr hatchets were all turned. On examining into the
cause of this, tbey found that the pillars were petrified through-
out, though the house had only been built ten years, and the

1 1 . Infktence ^Organic on Inorganic Bodies. — Mr Hessle, in
a memoir entitled *' Influence of Organic on Inorganic Bodies,"
{ Einflaens des Organischen Knrpers auf den Ijiorganischen,
Marburg, 18^), proves, in the introduction or preface, by ex-
amples, that organic remains have exerosed an influence upon
their mode of petrifying, and that the axes of the organized bo-
dies have determined the axis of crystalline petrifying sub-
stances. The petrifactions of the radiaria present crystallizations
of the rborabohedron, the regular Hx-sided prism, and the
straight cylinder. The author enumerates their various posi-
tions in petrifactions. He gives an idea of the nature and form
of the encrinites. The flrat chapter of this article contains the
' mechanical divinon of the stems of encrini, and the demonstra-
tion that the axis of the rhombohedron of the calcareous spar
corresponds with that of the stem, and the rhmnbohedron is
placed in it in four different waysj &c. The seoond chapter is
devoted to craisiderations respecting the positions of the rhombo-
hedrons in the aggregations of several pieces of encrinites. The
author enumerates all the possible comhinaticHis at the meeting
of two [Heces, and presents a table of them. He oon^ders the
double pyramid with three faces and turned, which results from
it, and describes the manner of observing these cases of meeting^.
In the third chapter he describes all the specimens which he has
collected, and which appear so numerous that they present a
large proportion of the possdhle combinations enumerated. Last-
ly, in the fourth chapter, he begins with otwerviog, that, in eac^
member of a branch of encrinus, the calcareous matter is placed
in different geometrical relations; he enumerates encrini par-
tially converted into pyrites and fluor; he asks of M., who
mentions the latter, to detennine the poation of the octahedron
of tlie fluor, &c. s

IS. On AnlAracitefOr GloMX-Coal. By A.. Basithaupt. —
It has beea long known that anthradte, or glance-co^, occurs
chi^y in the intermediary ibnnationB ; but opinions vary as to
its mode of existence in these formadrais. In all the localities
in which M. Breithaupt had an i^iportunity of observing it,
such as Wezzelstein and Saalfeld, Lischiuiz near Gerz, &c, it
presented itself in veins, never in beds. la the autumn of 1826,
M. de Wamsdorf discovered in the slate quarries of Wurzbach,
near Lobenstein, in VoigtJand, several quartzose v^s, one of
which amtained a very interesting variety of anthracite. It oc-
curs in isolated rods, which, like all the crystalline forms of
this species, go from rate of the sides to the other in a nearly
perpendicular direction. These flakes are surrounded by
quartzy fibres, po'pendicular to their lateral surfaces, and cmae-
quently parallel to the plane of the vein, which seems to jtfove
that th^ formation is posterior to that of the anthracite- M.
Breithaupt enumerates all the reasons which induce him to
cwisider these flakes as being really crystallized, and to refer the
anthracite crystals to the system of crystaUizatitHi of the prism,

13. On the probabie Oixurrence tftke Diamond in Siberia. —
It is expected that diamonds will be found in Siberia. A leUer
wiitten by a travelling naturalist to the rector of the Univ»«itj
of Dorpat, contains the following details : — The platiniferous
sand <^ Nischni Toura bears a striking resemblance to that o£
Brazil, in which diaBwnds are ccxnmonly met with. According
to the descripti(»i ^ven of it by M. Eschw^e, this sand is
prineipslly composed of rolled fra^ents of hydrate of iron and
jasper, and contains moce plaUna than gold. The Xischni Toura
saiid is visibly formed of the same component parts ; and the
presence of hydrate of iron in it is so much the more remarkable,
that it is in a conglomerate of the same kind that the Braailian
diamonds occur, that these two min^iJs are not associated
merely by accident, but are the debris of one and the same iot-
maUon. The author of this letter exphuns the reason why he
could not engage in the search for diamonds, in a place where
he is convinced they will be found. He communicated his ob~
servatioDB to the director of Nischai Toura, who appeared dis-
posed to commence operations.— -ZCTiwArj^? _/Mr Minerahgiet

14. Fossil Bones in tke Cave o/" Miremont.—'M. Brongniart,
in July 18S8, at a meeting of the French Academy of Sciences,
gave an account of a letter which he had received (torn M. Jules
Delanoue, dated Souffignac, near Miremrait, 15th July 1836.
The author of the letter bad discovered in the Cave of Mire-
moat, in the Department of the Dordogne, fossil bones in gene-
ral resemblii^ those whibh have been found in the caves of Ger-
many and England, and latterly in several of those of France.
In the description of this cave, inserted in the Annates des
Mmes (t. vii. p. 597, 18SS), it was remarked that no fossil bone
had been discovered in it; but at that period MrBuckland had
not published his inquiries respecting the position which these
organic remains commonly have in all the caves in which they
have been aucceasiTely (bscovered. M. Delanoue gives the fol-
lowing statements with respect to this new example of tbe sur-
prising constancy of this geological jdienomenoD : — The cave,
which is very large, is formed in a depont whii^ appears to be>-
long to the chalk, or to the formations intermediate between the
chalk and the jura limestone. It is of much greater dimenuons
than the plan inserted in the Annales des Mines indicates. The
galleries are so much the narrower the moke they are branched,
and are prolonged without any very remarkahLe ccmtraction or
(Natation, for 9000 yards or mote. All the galleries end in a
multitude of narrow and low ramifications, which may he com-
pared to the springs and brooks that feed k river. It was in
these parts that M. Delanoue found most of the bones. Tbe
floor b of red tenacious clay, containing ftagmenta of flint and
shells. Bones are not fouod either in the white mud, or in tbe
eaith. resulung from the cnin^ling of the walls, but in the red
cUy alone. The bones occur at all depths, as well as at tbe sur-
face. In the latter case they are friable and tffoken. They are
chiefly teeth and bones, which M. Delanoue supposes to belcmg
to the Ursus bombifrons, whose fosful remains are found at Iser-
lohn, and in other caves in Germany. M. Delanoue observes
that the Miremont cave presents no stalactites. This drcum-
stance, which had been already pointed out, is. rather rare in

vayeSf and especially in those containing bones, where these in-
crustations often cover the organic remains. By digging at the
diatances of SOO and 400 yards from the entrance, there have
been discovered, beneath Bereral layers of mar), which appear to
be of a much more recent fonnadon than that of the red clay,
the remains of pottery, which, in its colour and nature, presents
the greatest resemblance to the pottenea which are found,
though rarely, in some ruins, and in some depoata of modern
alluvia, and which, from the nature of thdr paste, th^r colour,
form, and other tnrcumstances, are referred to the times prece-
ding the introduction of Roman arts unong the Gauls.
14 On Coral Islands. — According to Linnaeus and Ellis,
the calcareous zoophytes, such as the tubipores, millepores, and
madrepores, are inhabited by animalcules, which have some af-
finity to the nereids, medusse, and hydrse; but more recent in-
vestigations have shewn, that all the corals which form rocks,
or Saxigenotis tithoph^es of the French zocdogists, and even
the Pavonia Caryophjfilea and the NuiUpora of Lamarck, serve
as a habitation to gelatinous mollusca of a particular kind, ot
are surrounded by them. Since Cook's voyage, Forster'a ob-
servations have given occa^n to geologists to think that many
islands and entire countries have owed thor origin to the coral
produced by these animalcules. I have seen stnne of these co-
ral islands covered with a pitiful vegetation, and. I have no
doubt that many of those of the Pacific Ocean have been form-
ed in this manner. It appears to me, however, that too much
importance has been attributed to this theory, on which M.
Adelbert de Chamisso, an excellent obso^er, has thrown much
light. In the West Indies, for example, hmestone rocks of ter-
tiary formation, which ^conttun petrified madrepores and tubi-
pores, have been taken for recent works of coral animals, mere-
ly because they ocxur in places where similar animals are still
observed. But when we penetrate into the interior of the large
Antilles, there occur mountains of primitive formation, which to
a great height are surrounded by the same madrepore rocks.
These rocks have, consequently, emei^ed from the chaos of an
ancient world. Between the tropics, on the shores- of the
Gulf of Mexico, the traveller runs the risk of confounding with

\5. On Brown Coal, or Lignite, and Oolite, sv^erimpoaed
on Chalk ,- ditamered m Seaaarabia by M. Eic^M. — In a
geological point of view, this l»own coal or lignite is chiefly
worthy of attention from the circumstance of lU fadlitating the
study of the tertiary rocks, which have hitherto been so little
examined. According to the commonly received geological opi-
nions, founded on the examination of mountains in Germany,
France, England, Switzerkmd, Italy and part of Scandinavia,
and confirmed by Humboldt^s observations in the mountains of
Anienca, lignites ought to occur with the plastic clay, above a
formation of chalk. In Bessarabia, the chalk formation ap-
pears at the surface, in the neighbourhood of Mohilef, on the
Dniester, and extends into Moldavia, in the north-east direction.
The formations »tuated between this chain of chalk mountains
and the sea preset no analogy to the tertiary formation q£
France. Here, above the chalk, there occur, 1st, To a fathom
and a half, a coarse sand ; id. An argillaceous rock, containing
some lime, and of which the lower part is somewhat silicious,

and compact limestone ; 5^, Lastly, the whole pU'm to the sea
and the Danube is solely composed of horizontal limestone, filled
widi shells. In the cavities of this piindpal formation, and ge-
nerally between the territory of Brender and the sea, in the di-
rection of north-west, there occurs silicious limestone, with re-
mains of shells, among which pinnitea are also seen. At a
great distance from the sea, on the banks of the Bouik, the
Ueoute, the Eoula, and other rivers, this limestone is covered
with soft marls containing crystals of selenite. From the line of
Brender to Boudjak, immediately over the sand, hes a trans-
ported limestone (Cidcaire meuble), otMnposed almost entirely
of shells, and more or less mixed with iron ochre. Large beda

16. Inquiries retpeeUng the PoUen of Vegetaiiet. — Oa the
Slat July 18S8, there wa§ read, to the Academie des Sciences,
a letter from M. Baspail, respecting the spermatic animalcules
which M. Adolpbe Brongniart thought he had discovered in the
pollen <^ veget^les, and whose existence M . Raspail persiels in
denying. The author, whose object was particularly to reply
to M. Brongniart's last memoir, mentitHied, that this young ob-
server having presented the poUm of the Mahacea, as that in
which be had met with the largest animalcules; it was toward this
same pollen that his own inquiries were naturally directed. The
result of these inquiries was the convictitm, that the alleged ani-
malcules were nothing but minute drops of substances soluble
in alcohol. M. Adolphe BrcHigniart admits, in his new work,
that resinous drops are emitted, in great numbers, during the
explosion of the pollen, a circumstance of which he took no no-
tice in his first memoir. Faithful to his first opinion, he how-
ever asserts, that these drops have nothing to do with his ani-
malcules; " but, in order to prove it to us," says M. Baqiail,
" in place of making the experiment upon the pollen of the
malvacese, he has recourse, all of a sudden, to the pollen of
other families, and finds, that, in these, the animalcules do not
dissolve in alcohol, but only lose their motion in it." As rean,
wax, and essential ml, do not, by any means, exist in Uie same
proportions in the pollen of difFerent plants, as M. Raspail has
proved in a former memmr, it is not surprising that M. Brong-
niart should not find, in the pollen of the graminete, so great an
abundance of reranous drops as in the pollen of the malvocese ;
or that he should see round bodies in it, which did not dissdve
in alcohol. But it is obviously on the malvacee that die expe-
riments in question ought to have been repeated. M. BrcHigniart's
mode of operating, also, is so inaccurate, that M. Rat^I is
compelled to doubt whether he employed his process in the
manner which he points out. He says he poured alcohol onthe
animalcules in motion ; in other words, and by consequence,
into the drop of water in which they were moving, and yet did
Ogle
ScknHfic InUM^mcc—Btoany. 999
not see them dissolve. " Now, alcohol poured upon water can-
not dissolve, at least instantaneously, drops of reain, as every
one knows who has been arcustomed to make experiments of
this kind. Moreover, it then produces so violent a microscofnc
tempest, that it becomes impossible for the observer to disdn-
guish any thing. In another experiment, the author covered,
with a plate of mica, the drop of water in which he had broken
a 'grain of pollen ; but, the plate of mica, at the moment when
he placed it upon the drop of water, must have renooved from
his view the bodies which it fixed ; and, besides, the edges <if a
plate of mica, which are always itl apphed ag»nst the object-
bearer, cannot, by any means, prevent the evaporation of the
fluid, which becomes a powerful cause of automatic motion.
We advise the author, when he proceeds anew with suc^ expe-
riments, to place a suffident quantity of wat^ and grains of pol-
len in the cavity of a plate of glass, and cover it with another,
making the latter slide over the former, without allowing the
air to indnuate itself into the cavity. The pollen will burst.
The explosion will indeed put the whole in motion, but, in a
few moments after, our little automatons will resume the immo-
bility of all inert globules. I have repeated these experiments
a hundred times. Many others have repeated them since ; and
M. Brongniart is hitherto the only perscMi who pernsts ft hold-
ing so ill-founded an opinion." The vague and indeterminate
motion, which aj^>ear9 to M. Brongniart so peremptory a proof
of the spontaneousness of the corpuscules in questitm, seems, to
M. Raspail, a proof of the contriu^ opinion ; for any globules
of albumen, gluten, starch, and still more of essential oil, sus-
pended in water, will prraent traces of a vague and indetermi-
nate motimi. '* I therefore," says M. Raspail in conclusion,
" persist in asserting, that GHeichen's pretended animalcules are
nothing, in the malvaces espedally, but resinous drops; and, in
other poDens, but inert globules of tissues mixed with these
drops.'' M. Raspail concludes bis letter with observations res-
pecting the comparative value of different microscopes. In his
opinion, JmicPs Microscope (which M. Brongniart employs, and
for this reason considers his experiments as peculiarly valuable),
is, other things equal, inferior to every other microscope. Any
one having the least knowledge of optics, might convince him-

ter, experience confirms. The most expert observers of Patis
have long remarked, that objects which are distiiictly seen with
the vertical adiromatic microscope, are not perceptible with
Amid's microecc^, and more than one observer has already re-
peated of having sacrificed the former, for the expenrave agate

18. On Ike Ch-gaHtzation of the genus CAora.— There waa
read to the Academie des Sciences of Pans, on the Slst July
18S8, a letter frtm M. Rasptul, respecting the organizatioD of
the genus Chora. Botanists and Natural Philosophers have
lutherto been much puzzled by the existence of two opponte
currents of green matter, in the interior o[ the tubes of this ge-
nus, which never intermingle, although there is no partition be-
tween th^D. M. Baspful gives a very ample explanation of this
singular phenomenon. " Having brought near the flame of a.
lamp," says he, " a tube closed at one end, and filled with alco-
hol, holding a multitude of ^obules of fat in suspension, I sotxi
observed a current of globules proceeding upwards on one ade,
and again descending on the other, to coatinue the same naotirai
without intemussion. So long as I kept the tube at the same
temperature, the two currents never mingled ; and, during the
whole oontinuance of the experimmit, th&K existed a viable line
of demarcation between them. In a word, my glass-tube waa
an exact representation of the tube of a chara, which is, in fact,
notlilng but a transparent tube closed at both ends, lined with a
layer of green matter, and in which there are distingui^ied an
ascending and descending ciurent." M. Raspul produced a
glass-tube contaming sawings of wood, of which it was sufficient
to heat the base with the hand, to produce the pbetunnenon.
The two currents were quidcly established after a few osdlla-
don& Then followed, in the letter, the physical explanation
of the {Aenopienon. In reality, in the chara, it is not the heat
that determines the twofold motion, but the aspiration and ex-
pration <^ water operated by the tube, as M. Baspail has al-
ready demonstrated. The phenomenon in question has also
been produced by him in glass-tubes, by means of an artifitaal
aspiration and expiration. — Le Ghbe, S6. JuiUet 18S8.

nto, disccKjered by Mr David Douglaa. — In Vol. xv. of the
Transactions of the Linnean Sodety, there is an account of a
new and interesting spedes of pine, from California, hy Mr
Douglas, vho proposes to name it Pinta Lambertina, and gives
the following as its specific character. P. fohis quinis ri^dis
scabrusculia, va^nis brevissimis, strabiUs crassis longissimis cy-
lindricis ; squamis iaxis rotundatis. It covers large districts in
Northern CaUfomia, about a hundred miles from the ocean, in
Lat 43° north, extending as far to the south as 4°. It grows
epariDgly upon low hills, and the undulating country east of a
range of mountains, running in a south-western direction from
the Rocky Mountains towards the sea, where the soil consists En-
tirely of pure sand. The trees do not form dense forests, like
most of the other pines which cover the face of North- West
America, but, like those of Pinua resivoia, are scattered HDgly
over the plains. The trunk attains a height of from 150 to
SOO feet, varying from 20 to near 60 feet in drcumference.
The trunk is unusually str^ght, and destitute of brandies
about two-thirds of the hei^t. The bark is uncommonly
smooth for such large timber, of a light brown colour on the
south, and bleached on the north side. The branches are ra-
ther pendulous, and form an open pjrramidal head, with that
appearance which is peculiar to the Abies tribe. The leaves
are ti^d, from 4 to 5 inches long, of a bri^^t green colour, and
grow in fives. The cones are pendulous from the' extremities
of the branches, and, when ripe, are about 11 inches in cireiun-
ference at the thickest part, and from IS to 16 indies in length.
The scales are lax, rounder, and destitute of ^nes. The seeds
are large, eight Unes long, and four broad, and of an oval form.
Their kernel is sweet and pleasant to the taste. The embryo
has twelve or thirteen cotyledons. The timber is white, soft, and
]ight. It abounds in turpentine reservoirs, and its specific gra-
vity is 0.463. The whole tree produces an abundance of am-
ber coloured rean. That which esudes from the trees, when
they are partly burned, loses its usual flavour, and acquires a
sweet taste, in which state it is used by the nauves as sugar,
being mixed with their food. The seeds are eaten roasted, or
are pounded into coarse cakes for their winter store. The ver-

nard presented to the French Academy of Sciences, in Augu&t
\S£tS, a substance, which was communicated to him by the Mi-
ntster for Foreign Affairs. This substance was sent to the Mi-
nister, as having fallen from the sky, in Fer^a, at the com-
mencement of the present year. It occurred in such abundance
that the ground was of a sudden entirely covered by it over a
great extent. In some spots it was five or six inches deep. It
was eaten by cattle, and particularly sheep; and bread was
made of it, which afforded nourishment to man. Such were the
accounts furnished to the French Consul in Fersia, by a Rus-
sian general, who was an eye-witness. M. Thenard bad first
presented the specimens to M. Desfontaines, who realized in
them a species of lichen described by botanists. These lichens,
which, it would appear, occur in very great abundance, bad
been transported by the wind to the jdaces where tbBr sudden
appearance was observed. A similar phenomenon occurred in
the same parts of Fersia in 18S4< *.
SI. On the Fecvndaium ofFlawert. — FtHmerly the fecunda-
tion of flowers, in which the sexes are separated, was almost
wholly attributed to the wind. Kohlreuter and Spr»igel have
proved, with an astonishing sagacity, that bees, wasps, and a
great number of small winged insects, perform the principal
part in this operation. I say the principal part ; for to assert
that the fecundation of the germen absolutely cwinot take {Jace
without the intervention of these litde anjmals, does not seem
to me in conformity with the genius of nature, as Wildenow
has demonstrated at length-f-. But, on the other hand, it must
be observed, that dichogamy, the coloured spots of die petals,
which indicate the vessels in which the honey is cont^ned, and
fecundation by the contact of insects, are three circumstaoces
almost inseparable. — Humboldt, Tabl. de la Nat. t. i. p. 78.

24. On the Tj^rian Purple. By M. Lesson. — Pliny has describ-
ed two kinds of sbells, in the 4th Book of his Natural History, as
furnishing the celebrated purple with which the robes of the Ro-
man nobles was dyed. He names the one Buccinum, the other
Murex. There has been much disagreement respecting the
bucdnum. On comparing Pony's description, however, with
tbe spedea of mollusoa which inbidHt the Mediterranean, there
can remain no doubt that it is the Janlfuna fragUis of modem
naturalists. This shell is pelade, and floats on the see in pro-
digious quantiues. It b supported at the surface by air veucles,
which Pliny calls a glutinous wax ; and the moment it retires
unda- the water allows to escape a very pure and bright reddish-
purple colour. Each animal contmns a con^derable quantity of
it in a dorsal vessel. With alkalies, this colour readily assumes
a green tint, and confirms what Pliny says cm this subject. What
is taken for a long tongue is the head of the animal, which is in
fact rounded, and of firm consistence. The Jonthina is ex-
tremely common in the Mediterranean and in the Atlantic, for
tbe shores of St Helena and the Island of Ascension are, at cer-
tain seasons, entirely covered with them. The second species
of purple appears to be really the Murex of the ancients, or the
shell named Chicoree, and not that called Purpura. Some im-
perfect trials that we have made with the colour <^ the Janthina

have satisfied us that it would form a very valuable reagent ;
for it passes very readily to red under the action of acids, and
returns to blue under that of alkidies. With the oxalate of am-
nunia, it gives a, precipitate of a deep blue colour, and with ni-
trate of ^ver a very pleasant grc^ish-blue c(Jour, which fur-
nishes a very good colour for drawing.
26. Microxopkal ObaervaUont on Fresh-Water Sftasela. —
M. Baspail read to the Academie des Sciences, on the 14th
July 1828, a letter, in which he detailed the results obtained
by him from new microscopical observations made on fretih-wa-
ter mussels. " Having placed,^ says the author, " on the Ist
July, two fresh-water mussels in a glass jar, I c^served that the
^ccrementilial extremity expelled at certun intervals a small
parcel of a yellowish-white colour, and about half a centimetre
long. This granular parcel, when torn asunder on the object-
bearer, gave out a number of small Invalvea, which opened and
shut thdr shells in a lively manner. Each of the valves was of
a triangular form, the binge forming the hypoth^use. When
open, they were one-third of a millimetre in length, and one-
sixth when closed. This triangular form disappeared when the
two valves ceased to be parallel to the object-bearer ; the animal
was scarcely distinguishable from the granulations of the shell.
In another parcel, I found bivalves furnished with an umbilical
cord, the commencement of which proceeded from one of the
notches formed by the commissure of the two valves.^ Lastly,
when these bivalves were placed on the edges of their sbeU, it
was easy to distinguish, on the umbo of each valve, an apex,
turned inwards, nearly at a right angle, formed by a rib, ri-
milar to that wbich in this potation surrounds each valve tike
a rim. But this apex was accompanied on each «de by a mem-
branous prolongation, which was attached to the edges of the
valves. M. B&spml mentioned the esperimenu which led him
to conclude that the apex of the young shells observed by him
is at that period formed solely of phosphate of lime, and that
there is scarcely any carbonate in it. Hb new observations con-
firm, Isf, What M. Jacobson has s^d respecting the two urn-
bones, which that author, however, has not, in bis opinion, de-
scribed with accuracy ; and, 3d, The existence of the umbilical
cord described by Koslreuter. But these observations invalidate:
3
ScierUi^ InteUigence. — Anthropolegi/. 405
M. Jacobaon^s opiiuon respecting the paramtic nature of the |
young sbelle, for how can it be concaved that paraates should
be contained in a parcel, like the e^s of the moUusca, and
ejected by the animal itself ? They also invalidate what M. de
Blainville has mentioned respecting a parcel of ^gs expelled by
the animal. As to M. Jacobson's argument, derived from the
presence of umbones in these young bivalves, in favour of the
opinion which consaders them as parasites, it does not appear to
me citable of bang adopted ; for, might it not be the case, that
these small umbones were already the rudiments of all those
protuberances which form on each edge of the valves on the
two sides of the hinge, and which are destined to give so great
a solidity to the two valves when they are appUed to each other f
These umbones are rather appendages inserted upon the rim of
the valves than a portion of the valves themselves."

86. DvDtr^tjf of taste respecting Food. — We have many ex-
amples of the partiality of comparatively civilized races of men
to a diet which to us appears loathsome and offensive, and which
these nations, from balnt, or naturally depraved taste, would
prefer to the choicest dishes at an alderman^ dinner in G-uild-
hall. The Pariahs of Hindostan (it is observed in a recent
work), attracted by the stench of rotten carcases, fly in crowds
to dispute the infectious carrion with the dogs, and other birds
of prey. They share the mass of corruption, and return to
their dens to devour it without rice, seasoning, or any other ac-
companiment. Little do they care of what disease the animal
may have died, for they make no scruple to poison secretly thdr
n^hbo'urs' oxen and cows to provide a savage repast for thdr
ravenous appetites. The bushmen of gouthem Africa generally
eat the flesh raw ; and when they cook it, they only warm it,
and apply their teeth to it the moment it is taken from the ashes.

dS the ■vBlage of Loakin, district of BalakhtiiTi, in the govern-

robust constitution, was married at seventeen. The second year
of her marriage she was brought to-bed of a girl, which died at
the end of fifteen days. The fourth year she was delivered, af-
ter a gestation of eight months, of twins. The first, which was
a boy, lived only five days ; the other, a girl, died after mx days
of the most cruel sufferings. In the month of November 1824,
the same woman won delivered of five children, brining succes-
sively into the world a §^rl on the 9th, 10th, 12th, and 13th,
and a dead boy on the l6th. Each of these infants was only
about eight inches long. The four girls died on ihe sixth day
after' birth. The mother was restored to perfect health in a
month after parturition. Nothing particular had been remarked
either by herself or by the midwife, with Ae exception of an tsL-

30. On ^predominance^ the R^htJrmfmer the Lefi. — M
le Comte, in a meaxHr relative to the predominance of the right
arm over rtie left, in the Journal de Phyeiolo^e Experimentale
for January 18^ commences with refuting the opinion of those
who have attributed this predominance to habit. He then
passes under review the different hypotheses of phyaologista,
who have, hitherto looked for the cause of this phenomenon in
tlie normal organization of man, and finds all that has been pro-
posed inadequate. He at length conies to his own hypothesis.
In his ojHnion, the difference between the right and the left sys-
tem has its source in the portion which the human fetus affects
in the uterus during the last months of gestation. In by &r
the greater number of cases, the portion is such that its left
arm and shoulder, as well as the left side in genera), are pres-
sed against the bone of the pelvis. From this pressure there
results a (jontraction of the bloodvessels, a sort of atrophy com-
mencing in the whole left system. The weakness of that side,
therefore, results from this congenital disposition. M. Comte,
with the view of obt^ning a verification of his theory, compared
the cases in which the fetus occurs in the poution which he con-
siders as calculated to determine the weakening of the left sys-
tem, with those in which it assumes a contrary position ; and he
has found a number which expresses the proportion of right-
handed and left-handed p^^ons. Having been for several years
a resident pupl in the Maison Royale d'Aocouchemens, M.
Comte occupied himself in observing the habits of the children
which, at the moment of their birth, he had supposed would be
left-handed, and he found his prognostications verified. He pro-
poses to make a further trial on the children placed in the Hos-
pice de Orphelins, with respect to whom it would be possible to
ascertain the peculiar circumstances that attended their hirUi.
He concludes with condderaljons respecting the means of eor-
abling children to use both sides freely. To ensure this hap-
py result, it is not enough to make children use both hands
aUke after they are two or three years old. To compensate the
defective condilion of the left system at the momait of Inrtb,

they must be forced to use it solely, leaving the right system id
a state of inactivity. The reverse of this is generally what takes
place. Nurses, in fact, usually carry children on the right arm.
In this position the child has the whole left side pressed against
the breast of the nurse, which cannot but increase the disposi-
tion acquired at birth. — BuUetm Universely April 1823.
SI. ArtificUd UUramarine. — M. Gay Lussac presented, at a
late meeting of the French Academy of Sciences, a specimen of
artificial ultramarine, manufactured by M. Guimet. He ob-
served, that this ultramarine, which ia of a quality superior to
that of the finest specimens hitherto sold, has been employed by
several painters, who have expressed their satisfaction with its
numerous excellent qualities. He menticaied also, that M. Gui-
met^s ultramarine may be delivered to the consumers at the rate
of 25 francs per ounce, or at two-thirds of the price of natural
ultramarine of good quality. As soon as M. Guimet's discovery
was announced by the public journals, a fOTeign chemist, M.
Gmelin of Tubingen, gave out that he also possessed a process
for the manufacture of artificial ultramarine. He even published
his recipe. M. Guimet, who keeps his a secret, is doubtful whe-
tfier ultramarine can be obuuned by M. GmeliD*s process at the
price at which he himself delivers it to commerce.
STATrsTICS.
32. Cidlure of Turnips. — Until the be^nning of the eighteenth
century, this valuable root was cultivated among us only in gar-
dens or other small spots for culinary purposes ; but Lord
Townshend, attending King George the First in one of his ex-
cursi(^s to Germany, in the quality of Secretary of State, ob-
served the turnips cultivated in open and extensive fields, as
fodder for cattle, and spreading fertility over lands naturally
barren ; and, on his return to England, he brought over with
him some of the seed, and strongly recommended the practice
which he had witnessed to the adoption of his own tenants, who
occupied a soil similar to that of Hanover, The experiment
succeeded ; the cultivation of field turnips gradually spread
over the whole county of Norfolk ; and, iti the course of time,
Seien^fic Inteliigejtce. — SiatitUct. 409
it has made its way into every other district of England. The
rqnitation of -the county as an agricultural dbtrict, dates from
the vast improvements of heaths, wastes, sheep-walks and war-
rens, hy enclosing and manuring — the fruit of the zealous exer-
bons of Lord Townshend, and a few neighbouring land-owners
— which were ere long happily imitated by others. Since these
improvements were effected, rents have risen in that county from
one or two shillings to fifteen or twenty shillings per acre ; a coun-
try of sheep-walks and rabbit-warrens has been rendered hi^ly
productive; and, by dint of management, what was thus gained
has been preserved and improved even to the present moment.
Some of the finest com crops in the world are now growing up-
on lands which, before the introduction of the turnip husban-
dry, produced a very scanty supply of grass for a few lean and
half-starved rabbits. Mr Colquhoun, in his " Statistical Re-
searches,^ estimated the value of the turnip crop annually
growing in this country at fourteen millbns ; but, when we fur-
ther recollect that it enables the agriculturist to reclaim and cul-
tivate land which, without its aid, would remmn in a hopeless
state of natural barrenness ; that it leaves the land so clean and
in such fine condition, as almost to insure a good crop of bar-
ley and a kind plant of clover, and that this clover is found a
most excellent preparative for wheat, it will appear that the sub-
sequent advantages derived from a crop of turnips must in-
finitely exceed its estimated value as fodder for cattle. If we
were, therefore, asked to punt out the individual who, in mo-
dem times, has proved the greatest benefactor to the communi-
ty, we should not be^tate to fix upon the ingenious nobleman,
whom the wits and courtiers of his own day were pleased to
laugh at as " Turnip Townshend." In something less than one
hundred years, the agricultural practice which he introduced
from Hanover has spread itself throughout this country, and
now yields an annual return which probably exceeds the inte-
rest of our national debt. — Sir Walter Scott, in the QMorter^
