PROCHEDINGS
OF THE
ROYAL PHYSICAL SOCIETY.
KIGHTY-EIGHTH SESSION, 1858-59.
Wednesday, November 24, 1858. Professor Baurour in the Chair.
The following Gentlemen were elected Members of the Society :—
William Carruthers, Esq. ; Wiliam Turner, M.B., Demonstrator of
Anatomy, University of Edinburgh. Foreign Member—Count Victor
Motschoulsky, St Petersburgh.
The Donations to the Library included the following, and thanks were
voted to the donors :-—

Author.—4. The Practical Naturalist’s Guide. By James Boyd Davies.
From the Author.
Professor Batrour then delivered the Opening Address as follows :—
It has been the usual practice in the Society that the retir-
ing President shall give a short address on the occasion of his
demitting office, and, in conformity with that custom, I have
been called upon by your Secretary to make a few remarks
this evening when I conclude my period of probation as Pre-
sident, ‘The task is by no means an easy one, from the diffi-
culty of finding some new topic of interest on which to ex-
patiate. The history of the Society has been already given
by my predecessors, and the obituaries of the eminent mem-
bers who have lately been taken from us (a topic which in
most Societies occupies much of the opening addresses), have
VOL. II. A
2 Proceedings of the Royal Physical Society.
already been given by Fellows of the Society, more competent
for the duty than myself. It has occurred to me that a brief
notice of two Edinburgh Natural History Societies, which have
now ceased to exist, and more particularly of the Wernerian
Society, might not be altogether uninteresting.
Natural History studies are peculiarly fitted to call forth
the principles of association. There is something connected
with the prosecution of them which draws students together,
and which binds them by ties of no ordinary kind. The study
of the Rocks and Minerals, Plants and Animals, of our globe
naturally leads to extended wanderings over mountain and
plain, by river side or ocean shore, during which the com-
panionship of friends becomes especially valuable and cheer-
ing. ‘There is a sociality in such pursuits which insensibly
unites men in scientific brotherhood. Those who have joined
in natural history excursions know well the fascination of such
rambles, and look back with pleasure to the friendships thus
formed. The collections made become also bonds of union.
For every naturalist knows the importance of the interchange of
specimens. ‘The system of exchange has led to the formation
of many associations. It was this which in a great measure
led to the institution of the Botanical Society of this city.
Edinburgh has been long celebrated for its Natural History
Societies. ‘The situation of our city, the rich fauna and flora
of its neighbourhood, its instructive geological and mineralo-
gical features, have rendered it one of the places best fitted for
the prosecution of natural science in its practical details. The
student has ample opportunities of pursuing science in all its
departments. Our museums and gardens also supply a valu-
able means of acquiring information. Thus it is, that as a
school of natural science, there is scarcely any city which pos-
sesses greater advantages. It might have been expected,
therefore, that scientific societies would spring up among us. .
_ The Physical Society was among the earliest established, and
it speedily acquired great eminence from the activity and zeal
of its members. It embraced the whole range of science, both
natural and physical, and it especially called forth the energies
of young men who were zealously cultivating science within
the walls of our University. It has had its reverses no doubt,
President's Address. a
. but it still exists, and has now entered on its eighty-eighth
session ; and though its resources are not so large as they once
were, the zeal of its members I trust is not abated. We have
among us many active naturalists whose labours have advanced
natural history, and whose original researches have increased
the fame and reputation of our school.
Besides the Royal Physical Society, there were other Na-
tural History Societies in Edinburgh, especially among the stu-
dents of the University. One of them was the Plinian Society,
which, during its short existence, tended much to foster the
spirit of inquiry, and to call forth the efforts of the junior
naturalists of Edinburgh. It was essentially a students’ society,
and met within the walls of the College. It began its ex-
istence on 14th January 1823, and continued to meet till about
the year 1835. It enrolled among its members many young
naturalists who afterwards acquired eminence, such as Wm.
Baird, now in the British Museum; M‘Viecar, now minister of
Moffat ; Jameson Torrie, well-known for his Natural History
labours in connection with his uncle Professor Jameson; Ains-
worth, who published Travels in the District of the Huphrates ;
Cheeke, the editor of a valuable Natural History Journal;
Malcolmson, celebrated for his geological pursuits in India ;
Anderson of Inverness, whose guide to the Geology and Na-
tural History of the Highlands is so justly praised; Robert
Grant, now Professor of Comparative Anatomy in London;
John Coldstream, one of the Fellows of our Society, whose
labours in Zoology are deservedly famous; Clouston, now
a clergyman at Sandwick, who has done much to elucidate the
flora of Orkney ; Woodforde, who published the Flora of
Edinburgh ; Lombard of Geneva; John Addington Symonds,
now a distinguished physician at Bristol; Hugh Falconer,
the Indian Botanist and Zoologist; Browne, one of the Commis-
sioners of Lunacy, and many others. If I were to analyse the
proceedings of that Society, I could show that many of those
gentlemen exhibited in their communications the early dawn-
ings of their devotion to those departments of science in which
they afterwards attained distinction. I feel that not a little
of the zeal with which I prosecuted botany was due to my
early connection with this Society.
4 Proceedings of the Royal Physical Society.
Unfortunately, like some other societies, it had its decay .
‘and decline, and, after a brief existence of about twelve years,
it ceased to exist. On 6th Febuary 1841, the society was dis-
solved, and its books and herbarium were divided between the
Royal Medical and the Hunterian Medical Societies.
In its flourishing days this Society was supported mainly
by students, and it is probable that its decline may be attri-
buted in some measure to the want of some zealous senior
members resident in Edinburgh, who, by associating with stu-
dents in practical natural history, would have kept up the
vigour of the Society.
We now come to another Natural History Society, the na-
ture of which differed essentially from that of the Plinian and
other student-societies, and whose period of existence ex-
tended over more than forty years, but which has also come
to a termination—I mean the Wernerian Natural History So-
ciety. This Society owed its origin to Professor Jameson,
whose enthusiastic devotion to natural history, and whose
eminence in mineralogy rendered his name famous all over
the world. TheSociety thus instituted by him was restricted
to senior naturalists. While it lasted, it rendered good ser-
vice to science, and by the publication of its valuable Memoirs
acquired a wide-spread reputation.
The Wernerian Society commenced in 1808, and the fol-
lowing is the record of its foundation :—
COLLEGE MusEeuM, Ldinburgh, 12th January 1808.
The following gentlemen being met, viz. :—
Rosert Jameson, F.R.S.E., Professor of Natural History.
Wititiam Wricut, M.D., F.R.SS. L. & E.
Tuomas Macknienut, D.D., F.R.S.E.
Joun Barcray, M.D., F.R.S.E., Lecturer on Anatomy.
Tuomas Tuomson, M.D., F.R.S.E., Lecturer on Chemistry.
Col. Stewart Murray Fuiierton of Bartonholm.
' Cuarztes Anperson, M.D., F.R.C.S.E,
Patrick Waker, F.L.S., Advocate.
Patrick Neiitu, A.M.
They resolved to associate themselves into a society for the
purpose of promoting the study of Natural History; and
President’s Address. 5
in honour of the illustrious Werner of Freyberg, to assume
the name of the Wernerian Natural History Society.
Professor Jameson having been called to the chair, the fol-
lowing office-bearers were unanimously elected :—
Professor Jameson, President.
Dr Wricut,
Rev. Dr ee a
Dr Barciay, and
Dr Tuomson,
Vice-Presidents.
;
Mr Waker, Treasurer.
Mr Neitz, Secretary.
It being understood that the Society should consist of
honorary, foreign, non-resident, and ordinary members, it was
moved by the president, and unanimously agreed to, that
Professor WERNER of Freyberg,
Sir JosepH Banks, Bart., President of the Royal Society, and
Ricuarp Kirwan, lsq., President of the Royal Irish Academy,
be enrolled as the first honorary members of the Society.
The following gentlemen were then chosen non-resident
members :—
Dr James Epwarpb Situ of Norwich, President Linnean
Society.
Rev. Dr Joun Stuart of Luss.
Dawson Turner, F.R.S., Yarmouth.
Rospert Brown, F.R.S., F.L.S.
The Hon. Mr Grevinte, F.R.S.
Cuartes Harcuert, F.R.S.
Count de Bournon, F.R.S.
Groree SHaw, M.D., F.BS.
Wm. Henry, M.D., Manchester.
And the following were elected foreign members :—
M. FrepEricx Mous, Styria.
Professor Karsten, Berlin.
Professor Kiaprotu, Berlin.
M. Von Bucu, Berlin.
6 Proceedings of the Royal Physical Society.
_M. Von Humeotpt, Berlin.
M. FReiustesen, Thuringia.
M. H. Meuner, Freyberg.
M. Herper, Freyberg.
Such then was the institution of the Wernerian Society.
On the 20th January 1808, the laws of the Society were
drawn up by a committee.
In regard to resident members it is ruled that the number
shall not exceed 100; and in regard to honorary members
that they shall not exceed 10.
- The meetings were held in the College Museum, or in a
room adjoining to it, at two o’clock in the afternoon.
All natural history specimens presented to this Society were
to be deposited in the College Museum.
A charter or seal of cause was subsequently obtained from
the Town-Council, and the Society was incorporated on 10th
February 1808, under the name of the Wernerian Natural
History Society.
The first meeting for public business took place on 2d
March 1808, in the College Museum.
The record of the proceedings of the Society from that time
up to April 21, 1838, is printed as an appendix to the published
Memoirs of the Society, vols. 11.-vil.
‘In these volumes valuable papers are given on various de-
partments of Natural History.

The Society continued to hold meetings with more or less
regularity up to 1850; and I have drawn up from its records
the following notices, in continuation of its published pro-
ceedings :—
On the 11th August 1838, the Society proposed to encour-
age the study of Natural History, by the offer of premiums
for the best essays on certain subjects in Hydrography,
Geology, Zoology, and Botany. These were subsequently
advertised. |
The thirty-second session of the Society was opened on
24th November 1838, by Professor Jameson; and on the
15th December of that year, papers were read by Dr Traill
on the Cheirotherium ; and by Sir John Dalyell on a singu-
lar mode of propagation in some of the lower animals ; besides
communications on the Geology of Melrose and Harlston, and
on Meteorology.
On 12th January 1839, Professor Jameson exhibited Lab-
rus trimaculatus and Gadus minutus, two rare fishes which
had been found in the Pentland Firth; and the carcass of a
large cinereous eagle, ‘“ being one of the two birds of that kind
which had the boldness to attack a traveller near Newton-
Stewart in Galloway.”
On 26th January 1839, Mr Smith of Jordanhill read obser-
vations on the elevated marine deposits in the basin of the
Clyde, accompanied with remarks by Deshayes, Lyell, and
Sowerby, on the shells unknown as British imbedded in
them, from which it appeared that, out of twenty species,
seven are at present to be found recent in the Arctic Seas, five
in the Crag and Sicilian Newer Pliocene, and that the rest
are peculiar to the deposit in question. Edward Forbes was
proposed as a member by Professor Jameson, and his nomi-
nation was seconded by Dr Neill. He was admitted on 9th
February. At the same meeting, Professor Wallace explained
8 Proceedings of the Royal Physical Society.
by a model his solution of the Miner’s Problem, in reference to
the security of the foundation of the houses in Moray Place.
On the 23d February, Mr E. Forbes read a communication
on the Asteriadee of the Irish Sea, which was afterwards pub-
lished in the Society's Memoirs. This was one of Forbes’s
early papers, and gave indications of what might be expected
from his natural history labours.
On 9th March 1839, Mr Cunningham read a valuable
paper on the Geology of the islands of Eigg, Rum, and Canna,
which was subsequently published in the Society’s Me-
moirs.
The session was closed on 20th April 1839; and the twenty-
third session was opened on 23d November, when, among
other notices, I find that Edward Forbes was made a mem-
ber of Council.
On 7th December 1839, Mr R. J. Hay Cunningham read
an essay on the relations of granite and trap to stratified
rocks, illustrating it by twenty-six large coloured sections,
showing numerous contortions, in which there is no evidence
of the granite having been forcibly injected so as to produce
shifting. Mr Macgillivray exhibited a specimen of the but-
cher bird (Lanius excubitor), shot at Whittinghame by Mr
Archibald Hepburn.
On 21st December 1839, a communication was read from
Professor EKhrenberg on the calcareous and siliceous micro-
scopic animals which form the chief component parts of chalk
and its associated rocks. Dr Greville stated that Mr Shuttle-
worth considered many of these organisms of Ehrenberg to be
of vegetable origin. Mr Stevenson mentioned that, up to Ist
December current, no snow lay upon the mountains of the outer
Hebrides, which, in ordinary seasons, were clothed with snow
in the end of October or beginning of November; but that
wild swans were abundant in the lochs, indicating a severe
winter in Iceland and Faroe.
The Society would appear also to have extended its opera-
tions beyond the ordinary limit of science; for I find in the
minutes of 12th January 1840, “on the motion of Professor
Jameson, it was unanimously agreed that the members of
this Society will give all possible countenance and encourage-
President's Address. 9
ment to a Society lately formed in Edinburgh for the preven-
tion of cruelty to the inferior animals.”
On 25th January 1840, Forbes read an account of the En-
tozoa of the Cydippe pileus, showing that, besides a Filaria,
there is a curious tongue-shaped parasitic animal, which was
first detected by Major Playfair of St Andrews, and has been
ealled by Forbes Tetrastoma Playfairit.
On 22d February 1840, Lord Greenock’s discovery of Sul-
phuret of Cadmium in rocks on the banks of the Clyde is no-
ticed, and the mineral is called Greenockite by Professor
Jameson. Mr Cunningham read a paper on the Geognosy of
the Island of Arran.
On 7th March 1840, Mr Bald read a notice regarding the
extent and commercial value of the blackband ironstone in
Scotland; and Mr James Wilson recorded the result of Mr
Shaw’s observations on the fry of the salmon. :
On 4th April 1840, Professor Jameson proposed that the
Society strongly recommend the measuring of the heights of
the coast lines of Fuci along the shores of Scotland, the Hebri-
des, and the Orkney and Shetland Islands; and the Soeiety
accordingly remitted the subject particularly to Dr Greville,
Mr Robert Stevenson, and Mr Edward Forbes; and further
directed the Secretary to intimate the recommendation to the
Rey. Charles Clouston of Sandwick, Dr George Johnston of
Berwick, and Dr Edmonston of Unst. Professor Jameson
showed specimens of compact felspar of great hardness, from
a bed which has occurred in the deep cutting for the Edin-
burgh and Glasgow Railway, very near Winchburgh, and
has greatly impeded the operations.
On 18th April 1840, Edward Forbes made observations on
certain rare British zoophytes, illustrated by drawings.
On 14th November 1840, Mr John Goodsir is recommended
as a member by Professor Jameson and Dr Neill; and he
was elected on 29th November. At that meeting, Forbes
read a communication on the classification of Mollusca.
On 12th December 1840, Dr Richardson sent a communi-
cation on the frozen soil of North America. Mr Goodsir
read an account of certain peculiarities in the structure of the
short sun-fish (Orthagoriscus mola), as observed in a large
VOL, Il. B
10 Proceedings of the Royal Physical Society.
specimen lately captured in the Firth of Forth, near Alloa;
and on 9th January 1841, he gave an account of the ana-
tomical structure of Ascidiw, showing that even the rough
covering of these animals is highly vascular; and at the same
meeting, Mr Jameson Torrie noticed traces of former glaciers
in the south of Scotland, and mentioned the occurrence of
fossil trees near Galashiels.
On 23d January 1841, Edward Forbes made a communica-
tion on the Natural History of Echiurus and Thalassema, two
genera of Echinodermata; and Mr John Goodsir explained
the structure of these animals. Forbes also noticed a new
genus of British Helianthoid Zoophyte, called by him Capnea.
On 6th March 1841, Dr Fleming gave an account of a new
British species of Raia.
On 17th April 1841, Mr Goodsir read a communication
from his brother, Mr Henry Goodsir, containing an account
of a new genus, with description of new species, of Pycno-
gonide ; also, an account of Pelonaia, a new genus of tuni-
cated mollusca.
On Lith December 1841, an account of St Kilda and its
Natural History was read, as transmitted by Mr John Macgil-
livray.
On 28th April 1842, Professor Jameson exhibited the follow-
ing fishes which had been taken in the Firth of Forth, chiefly
in Aberlady Bay:—1. Tunny, 8 feet long, and 5 feet 6 inches
in circumference where thickest. 2. Portbeagle Shark, 7 feet
3 inches long, and 4 feet in circumference. 3. Great Sun-fish,
5 feet 2 inches long, and 2 feet 8 inches deep. 4. Conger
Hel, 6 feet 6 inches long, and 4 feet 10 inches in circumfe- —
rence. He also exhibited a beautifully spotted Seal, 5 feet
6 inches long, by 4 feet 3 inches in circumference, accidentally
entangled in a herring net at Inch Garvey, near Queensferry.
On 26th November 1842, Forbes was elected Vice-President.
On 10th December 1842, Mr Torrie read a paper by Mr
Henry Goodsir, on two new genera of crustacea, to be called
Bodotria and Alauna, found by him in the Firth of Forth.
Dr Traill gave an account of Hlaps Jamesoni, a new serpent
from Demerara.
On 25th February 1843, Mr John Goodsir read a notice
President’s Address. LL
from his brother, Henry Goodsir, of the Maidre,—a vast ac-
cumulation of minute marine animals, which precede the ap-
pearance of a herring shoal off the Isle of May. He described
also a new species of Cetochilus.
Mr Goodsir continued for many seasons to give interesting
anatomical communications from himself and his brother.
In February 1845, Dr Traill read a paper on the arrange-
ment and character of serpents, while John Goodsir gave a
description of Neuronoia Monroii, a species of Entozoon, in-
festing the nervous system of the Gadide.
On 7th March 1846, Mr Goodsir communicated original
observations on the organs of circulation of the Echinodermata.
_ 28th March 1846, Dr Fleming read a paper on raised beds
of shells occurring on the coasts of Scotland; and Mr John
Goodsir read a paper on the anatomical structure of the Hy-
peroodon Dalei, taken from a specimen stranded near Alloa.
And on 19th December 1846, Professor Goodsir exhibited the
living larva of Medusa aurita.
On 20th February 1847, Professor Goodsir read a paper on
the morphological constitution of the skeleton of sponges.
od April 1847, Dr Martin Barry read a paper on the nu-
cleus of the animal and vegetable cell. On 27th November
1847, the completion of the bust of Professor Jameson is re-
corded, and a statement is made as to its being placed in the
Museum. There was no meeting from 27th November 1847
till 22d April 1849, owing to Professor Jameson’s illness.
Meetings became very irregular. In 1849, the forty-third
session commenced on 24th November, and that was the only
meeting for the session.
The forty-fourth session commenced on 23d November
1850, Professor Jameson in the chair. The president stated
on the occasion that Dr Neill, the secretary, was prevented
from attending by illness, a circumstance which he believed
had not occurred previously in the history of the Society since
its foundation in 1808. At this meeting Messrs Torrie, Gre-
ville, and Hamilton, were requested to act pro tempore as
secretaries.
The Society then adjourned, and did not again meet for
business.
12 Proceedings of the Royal Physical Society.
The minute is signed by Robert Jameson, President.
In March 1856, a meeting of the members of the Society
was summoned to consider its state and prospects.
The circular calling the meeting was subscribed by Messrs
Adie, Fleming, Traill, Jardine, and Balfour, V.P.; Greville,
Trevelyan, Goodsir, Deuchar, Councillors; Ellis, Treasurer ;
Torrie, Secretary ; Wilson and Hamilton, Librarians.
Various meetings took place on the subject. Proposals
were made to revive the Society, and many members pro-
mised active support. But after full consideration it was
finally resolved, in November 1857, to wind up the Society’s
affairs, and transfer the funds and property in certain pro-
portions to the Royal Physical and the Botanical Societies.
Here, then, we have another instance of the failure of a So-
ciety which had during a long period a career of no small
celebrity and usefulness. ‘To what are we to attribute this ?
Chiefly, I think, to the fact of its absolute dependence on one
man, Professor Jameson. Nothing was done without his
sanction. He was perpetual president, and no meetings were
called except by him. Along with the worthy secretary, Dr
Neill, he managed all the business ; and when, during the lat-
ter years of life, the Professor was incapacitated from taking
an active part in the proceedings, no meetings took place, and
the Society languished; and on his death all attempts to re-
suscitate it were found to be hopeless. -
The connection of the Society with the Museum led, in a
certain degree, to its dependence on the Professor of Natural
History. Its dissolution is traced, then, to the want of an in-
dependent council, who could manage its affairs and keep up
its membership. It possessed ample funds, a good museum,
many books, as well as other property ; but it wanted zealous
and active members to carry it on, and its exertions were crip-
pled by the ill health of its president, who was allowed to be the
sole motive power.
_ We have thus seen a student-society (Plinian) failing from
want of successors to keep up the business with spirit, from
depending on the fluctuation of natural-history zeal among
students, and from the absence of senior men to co-operate
with them and carry on the work; and we have seen another
President's Address. 13°.
society (Wernerian) fail from decline of activity among senior
naturalists, and the want of the infusion of young blood to
carry on the scientific circulation.
Our own Society, the Physical, has had its times of pros-
perity and adversity, but it has survived all shocks, and its
success seems to be owing, in a great measure, to the well-as-
sorted co-operation of senior and junior members. The zeal
and enthusiasm of the young naturalist has imparted anima-
tion to all; while rash theorising or hasty generalizations have
been curbed by the prudent councils of such veterans as Flem-
ing. There is a wholesome balance, which enables the Society
to exhibit its vitality in well directed efforts for the advance-
ment of true science.
The Society does not confine itself to the mere reading of
papers and communications, but encourages active practical
operations among its members. Its Committees for dredging,
and for the prosecution of geology and of entomology, are well-
fitted to bring out the zeal of its Fellows, and to initiate the
junior votaries of science in the details of field work. Such a
system is calculated to secure the permanence of the Society,
and to produce valuable results. Mere reading will never
make a man a naturalist. He must touch and handle the
ipsissima corpora, and must observe the phenomena as pre-
sented to his senses by nature itself. Researches conducted
under the auspices of those who have already in some mea-
sure mastered a science are of the highest value to the tyro.
If we wish the Society to go on prosperously, we should
encourage young men to enter while they are studying here.
We may thus hope to raise up naturalists who will do good
service in after life, and who, when they visit different quarters
of the globe in future years, may be expected to contribute
papers to the Society, which may be published in our Pro-
ceedings.
On looking over the Records of the Society’s Proceedings for
last session, I find that Zoology has occupied the most pro-
minent place. We have had a series of most valuable ori-
ginal papers on British Zoophytes, by Dr T. Strethill Wright,
one of the best observers of the present day. We have also
enlisted in our service one who devotes himself now entirely
14 Proceedings of the Royal Physical Society.
to natural history, Mr Andrew Murray, who has enriched our
Proceedings by his Zoological papers, and particularly his
contributions on the Coleoptera of Calabar, and the Ma-
lapterurus beninensis. To Dr Cleland we owe some valuable
anatomical papers, especially on the structure of Malapterurus ;
and we also owe our thanks to Dr M‘Bain, and Mr Peach,
and to Dr John Alex. Smith, our indefatigable Secretary, for
their excellent papers.
We have to lament the want of the contributions to Geo-
logy which used to come to us from the pens of Fleming and
Miller, and we have not been able during last session to in-
duce other geologists, such as Mr Chambers, to favour us with
papers.
We may hope that this session will be characterized by
greater vigour in all departments.
For myself I must plead guilty to having done little for the
Society, chiefly because my botanical efforts are made in con-
nection with the kindred Botanical Society.
I would desire to urge upon all the members the importance
of bringing before the Society communications, however short,
on the departments of Natural and Physical Science to which
they are attached. There are few indeed who cannot contri-
bute something. It is impossible for a careful observer, when
he examines natural phenomena, not to detect some point of
interest which has been overlooked. Brief notices are always
useful, and no one should be deterred from coming forward by
an idea that what he has to state is not of much importance.
Let the young naturalist begin at once to record his observa-
tions,—-let him get into the habit of noting facts as they
occur,—and he will find the benefit of this mode of procedure
in his after career.
We have before us a noble and inexhaustible subject of
study. None is better fitted for mental training, and none
exercises a more beneficial effect on the observing powers.
At the present day natural history is assuming a higher
position in our courses of study, and as a Society we are called
upon to aid in promoting such a system of education as shall
render our Edinburgh school famous in the annals of science.
The phenomena presented by the material world around us

are well worthy of our earnest study, whether we regard them
as means of exercising our mental powers, or as leading us to
higher views of Him who has created all things, and for whose
pleasure they are and were created.
The followers of science have sometimes been blamed for
attempting to subvert religion by their speculations. There
can be no doubt that in former times, and even at the present
day, some have started theories which have a tendency to
shake the faith of weak naturalists. But these are opposi-
tions of science falsely so called,—vague theories not founded
on facts. There is no fear of true science in its bearings
on religion. It is only want of science which produces any
jarrings. The more we investigate the wonders of creation,
the more we shall see the harmony which subsists between the
Word and the works of God.

ReEIn-DEER (Rangifer Caribou).—In my last communica-
tion on this subject, I drew attention to the antlers of the
American rein-deer,—their peculiar form, their mode of
growth, and the habits of the animal,—as bearing on the
question of its identity with the Lapland rein-deer, and made
some suggestions and speculations, with the hope that they
might lead some of my correspondents to inquire more par-
ticularly into these points, and give us reliable information
upon them, which might enable us to come to a correct con-
clusion on the subject. I am happy to say, that these ob-
servations have had the desired effect, and that, with an
additional supply of horns and heads, I have this year re-
ceived divers remarks on the points I indicated for inquiry.
One intelligent correspondent, Mr J. Mackenzie of Moose
Factory (from whose communications I have received much
satisfaction), goes at some length into the subject, and his
information, as to the time of the year when the horns are
cast at the different periods of the animal’s life, clears up the
discrepancies which have been noticed in the statements of dif-
ferent authors on this subject. It will be seen that the casting
16 Proceedings of the Royal Physical Society.
takes place at different times in the young and older animals.
I cannot do better than bring his views before the reader in
his own words, particularly as he comes to a different opinion
from that which I felt disposed to adopt on one or two of the
points which I speculated upon. Mr Mackenzie says—‘ I
have consulted one of our most intelligent natives, a man of
about sixty years of age, who has been a deer hunter from his
youth, and the result of our “ conference” I will presently
give you. I send by the shipa deer’s head and antlers, which
were received about last Christmas, and said to have been
killed early in December; it bears some resemblance to the
North American species, a representation of which is given
in your pamphlet, although the brow antler, however, forms a
small angle with the head, and does not come down parallel
with it, as in the heads sent you by Mr Hargrave; it has also
a second projecting prong, bent near the head, without any
terminal points or fingers, but these it would have had, had
the animal lived a year or two more; indeed the horns do not
cease growing till the seventh year. I do not believe that
the brow antler 1s intended for the purpose of clearing away
the snow, but is intended rather as a means of defence against
the animal’s numerous enemies. The wolf, wolverine, and lynx,
destroy them, I am informed, in great numbers; but the ani-
mal, on its guard, appears to me to have a good means of
defence in his browantler. Generally, however, he is taken at
a disadvantage ; when lying down, and off his guard, the lynx
(of the cat tribe) moves stealthily along, and with a bound
springs upon his back, and fastening his claws in his neck
and throat, worries him to death. The wolf and wolverine
are not numerous (the latter, indeed, is rarely found) in
this part of the country, but of the three the latter is the most
savage, and with: him the deer has little chance of escape
when attacked. Indian opinion here is, that for clearing away —
the snow, the animal uses his fore-legs alone ; and whether it
is hard or soft, they are well adapted for the purpose. My
own opinion is, that our rein-deer is the same as the Lapland
rein-deer. The following information, collected as I have al-
ready mentioned, may tend to throw some light on the subject.
The rutting season is in September; the females carry

their young till the latter end of May or beginning of June,
or till the d/ast snow is disappearing. The horns begin to
grow in about a month; at the end of the year they fall off,
being about 8 inches long, and not branched; at the end
of the second year they are about 13 feet long, curved, and
with terminal points, and are cast off in spring; the third
year the front and brow antlers commence to grow, but are
not large at the end of the year, and are cast off again in
spring; the fourth year they are larger, but not full-grown, and
are cast off in spring; the fifth year they are still growing,
and are cast off in March ; after the fifth year they are cast
off in November. ‘The Indian also states, that the antlers
have a variety of shapes, and that it is rare to find two exactly
alike. With regard to the training or domestication of the
rein-deer I can say nothing from my own experience, nor from
that of any Indian at this place; but I may mention, that I
have recently seen a gentleman who passed many years near
the head waters of the River Synauria (a river which falls into
the St Lawrence, near the Town of Three Rivers, in Lower
Canada), and that he had seen a young rein-deer among the
Indians as tame as a lamb; it entered the lodge, and fol-
lowed its master like a dog; but it was at last killed by the
dogs.”
Mr Mackenzie’s observations will be of use in correcting
misconceptions on one or two of the points alluded to by me.
It would appear that the American species uses its feet in
clearing away the snow from its food, as much as the Lap-
land species does; and the cup-shaped structure of its feet,
as shown in the specimens now sent home, is admirably
adapted for this. That it does not use the projecting shovel-
like brow antlers for the same purpose I am less willing to
admit; the apparent adaptation of their form to this pur-
pose induces me to defer forming a definite opinion upon it
until further information be obtained; the rather that, how-
ever intelligent and truthful the Indian referred to by Mr
Mackenzie may be, his statement is merely negative, and
is inconsistent with the observations of such authors (few in
number though they be) as notice the point.
As to the identity of the Lapland species with the North

American, we cannot expect to arrive at any correct result,
until we have the means of making a more complete compara-
tive examination than has yet been done of the two species
alongside of each other. Notwithstanding the greater dis-
tance of its locality, we possess both better materials and
more accurate information on scientific points regarding the
species from North America than that from Lapland. It
is to the latter that our inquiries should now be directed, and
more accurate information sought for on such points as the
periods of growth and shedding of the horns, referred to in
my previous communication, and in Mr Mackenzie's letter.
His statements on this point have been confirmed to me by
Mr Hargrave, who also informs me, that the head with distorted
horns, sent last year, which was figured in the first part of this
paper, was that of a young animal, not more than two years old.
He mentions, that a slight bend is common in the first year ;
that this becomes of the distorted form above referred to in the
second year, but afterwards disappears. I was misled, by the
teeth being much worn, into the supposition that it was an old
animal. These worn teeth must be the milk teeth; and we
thus have incidental information as to the period the animal |
carries them.
Information on such points becomes of importance, because
the North American and Lapland species are so closely allied
to each other, that we cannot expect to find distinctions of a
prominent nature, and must be content with the accumulation
of those of a more subordinate character. I may notice, that
I find the view which I adopted—viz., that the species are dis-
tinct—has also been entertained by Professor Spencer Baird
of America, who, in his recent « General Report upon the
Zoology of the several Pacific Railroad Routes, Part [—
Mammal,” includes two species of rein-deer as inhabiting the
northern shores of North America (the Rangifer caribou and
Rh. Gronlandicus), and both distinct from the Lapland deer; at
the same time admitting that their distinctness is questionable.
MooseE DrsEr (Cervus Alces, Lin.).—Mr Hargrave has had
the kindness to send me a magnificent head and horns of this
fine elk, which is another animal as to whose identity with its
Natural History of the Hudson’s Bay Territories. 19
European representative we are still in doubt. The Scan-
dinavian elk is undoubtedly very near it, if not the same.
The enormous palmation and weight of the horns in this
species is very striking. Colonel Smith says that the horns
sometimes weigh fifty pounds. The present specimen weighs
32 1b., but that is inclusive of the head. Sir John Richardson,
in his account of the animal, records a statement relating to
the horns of deer which I think must have originated in some
curious mistake. Speaking of the moose deer, he says,—‘“ It
is probable, however, that La Hontan in this passage con-
founds the Canada stag and moose deer together. He men-
tions the animal being able to run in the summer season for
three days and nights in succession, and the excellent flavour
of its flesh—facts which apply to the moose deer, but not to
the Canada stag; on the other hand, the weight of the horns,
which he says sometimes amounts to four hundred weight, is
true only of the stag.” Now, the Canada stag, or wapiti, is
the representative of the red deer in America, and was in-
deed long thought to be identical: it is a larger animal than
our stag, but smaller than the moose, which is as high as a
horse. Large specimens of the male moose are mentioned,
which have attained a weight of eleven or twelve hundred
pounds ; and is it possible that a smaller animal should have
horns weighing four hundred weight? I suspect a cypher
has been added, and that we should read 40 lb. instead of
400, which would then make it clear that the animal referred
to by La Hontan was the moose. With regard to the moose
being able to run for three days and nights in succession, an
instance of its doing so is recorded in the narrative of Captain
Franklin’s second journey, where three hunters pursued a
moose deer for four successive days, until the footsteps of the
deer were marked with blood, although they had not yet got
a view of it. At this period of the pursuit, the principal
hunter had the misfortune to sprain his ankle, and the two
others were tired out; but one of them having rested for
twelve hours, set out again, and succeeded in killing the
animal, after a further pursuit of two .days’ continuance.
The cause of the footsteps being marked with blood might be
from the phalanges of the hoof splitting, or possibly from the
20 Proceedings of the Royal Physical Society.
hoof becoming worn down by incessant and long-continued
action on the icy crust of the snow. We are accustomed to
hear of the cattle in long journeys in the Cape of Good Hope
and Australia becoming knocked up, and the traveller being
arrested in his journey by the failure of his beasts of burden.
I daresay many people entertain the idea (as I did myself)
that this knocking up was the consequence of physical exhaus-
tion on the part of the cattle. Mr Ford, one of the best zoolo-
gical draftsmen in Britain, first enlightened me on this point.
He had accompanied Dr, now, deservedly, Sir Andrew Smith
in one or more of his exploratory expeditions to the interior of
the Cape; and he told me that this failure of the cattle was oc-
casioned, not by exhaustion, but by the actual wearing away
of the hoof, till blood oozed from it at every pore. The Cala-
hari desert was particularly obnoxious, as it is composed of a
slaty formation, highly inclined, which shivered easily off into
sharp fragments. It was like walking on bundles of pen-
knives, with their edges placed upwards. The cattle gave in
sooner in this desert than in any other district, in consequence
of the greater abrasion of the hoofs upon this slaty formation;
and, till they grew again, the animal was useless, and scarcely.
even to crop its food, would it stir from the spot where it was
unyoked. I do not know what length of time would be
necessary to incapacitate an ox,—of course, it must be vari-
ous, according to the extent and nature of the ground tra-
velled over; but although soft snow might protect it longest,
T imagine the brittle fragments of a hard frozen crust of snow
might be not much less destructive than the slaty splinters of
Calahari.
I have examined the hair of the moose deer, and find that
its structure is the same as that of the rein-deer, which I
have already described in my paper last year.
ALPINE Hare (Lepus glacialis, Leach).—This beautiful
hare furnishes an admirable example of the adaptation of struc-
ture to habit. For heat and comfort nothing can surpass its
thick, delicate, white fur, which, on the under side of the
paws, assumes such a compact, double-plied, felt-like cha-
racter, that one would think no degree of cold could penetrate
Natural History of the Hudson’s Bay Territories. 21
it. The whiteness of its colour also is so pure that it is most
difficult to discernit on the snow. Sir John Richardson notices
that in one of the boat voyages in which he took part along
with Franklin, they landed on a rocky islet off Cape Parry,
which, although not above 300 yards in diameter, was ten-
anted by a solitary Alpine hare. The whole party went in
pursuit of this poor animal; but it availed itself so skilfully
of the shelter of the rocks, and retreated with so much cun-
ning and activity from stone to stone, that none of them could
obtain a shot at it, although it never was able to conceal itself
from their search for more than a minute or two at a time.
‘Its flesh is said to be better eating than either the Ameri-
can or Huropean hare.
QueBEC Marmot (Arctomys empetra, Schreb.)—This ani-
mal, although recorded as being found in the Hudson Bay
Companys territories, would appear to be confined to their
southern parts. Ihave received none from my northern cor-
respondents, but only from Canada, where it would appear not
to be rare.
Musk Rat (Fiber zibethicus, Cuv.)—This is a very com-.
mon species in the Hudson Bay Company’s territories, and
supplies a large portion of the furs sent to this country. Its
skin is used as medicine or medicine-bags by the natives, in
which state the specimens sent to me have arrived.
BEAVER (Castor Americanus, Brandt).—Considering the
immense number of animals both of this, and more especially
of the preceding species, which have for a long series of years
been taken for the purpose of supplying the wants of civi-
lized Europe, we might have expected that specimens would
be by no means rare in our museums. The contrary is the
case, however, so much so that when my friend Dr J. A.
Smith a year or two ago wished to compare the semi-fossil
bones of a beaver found in a superficial deposit in Scotland
with the recent skeleton of a beaver, the comparison could not
be made in Scotland from want of a specimen of the re-
cent animal in any of the museums in that country. I
22 Proceedings of the Royal Physical Society.
applied to Mr Mackenzie to assist us in remedying this
deficiency, and he has very kindly done so by sending both
a full-grown living beaver, and a foetus taken from the
mother before birth. In sending a living specimen, Mr Mac-
kenzie remarked that it would probably ultimately answer the
purpose of a skeleton, should the climate of Edinburgh not
agree with the animal’s constitution. I had destined it for
the pond in the Edinburgh Royal Botanic Gardens, where
Professor Balfour could have given those interested in natural
history an opportunity of studying its habits at their leisure.
It might easily have been kept alive if it once had reached the
gardens. There would have been no difficulty in supplying it
with birch twigs and branches, its native and proper food;
and Mr Mackenzie informs me that it is by no means par-
ticular in its food, and that if it had the run of the kitchen
(that is, I presume, the opportunity of selecting what it chose
from the debris of an ordinary family’s table) it would do
very well. Unfortunately, it never got the chance of trying
the climate of Edinburgh, nor we the chance of trying experi-
ments upon it or its food. Itreached London alive, but that
wasall. It died next morning. It was, however, carefully
transmitted to me, and along with the foetus received last year
was presented by me to Professor Goodsir, who has under-
taken to make a careful dissection of it, and to communicate
anything he might think of interest. There are a number
of points in the internal anatomy on which information is
wanted, such as the castor, and the glands which produce it, and
others which might throw light on some disputed (I cannot call
them doubtful) points in its economy and habits. For instance,
we know from Hearne, that the usually received notion that the
animal uses its tail as a trowel to plaster its work, is merely a
vulgar prejudice, arising from its flapping it on the ground
occasionally, and more particularly when about to plunge
into the water. Now an examination of the muscles of the
tail might, were it necessary, throw light upon this point.
But I imagine that the whole structure and habits of the ani-
mal explain the use of the tail sufficiently even without ana-
tomical assistance. On examining its external peculiarities we
find that its fore paws and feet are short and comparatively

small and weak, and not provided with a web; the claws are
strong, and well adapted for digging, but not equal to those
of the hind feet. The hind feet and legs are enormously
strong, the fingers united by a strong broad web, the claws
excessively developed, and each in the form of a strong gouge.
The combination of machinery in the fore and hind legs and
feet thus corresponds with what we know of the habits of the
animal so far as that can be observed; and the structure of
that portion whose working is difficult to be observed in action,
or has not been noticed sufficiently, shows what its real work-
ing is. ‘Those who have observed the animal in its native
haunts, tell us that it uses the fore paws for carrying the mud
and stones used in its constructions, and that it carries this
stuff between them and its breast, which quite corresponds
with their attitude in my dead specimen. It no doubt uses
the fore paws for other purposes, as digging, swimming, and
walking (for nature seldom or never creates an organ merely to
fulfil one purpose). As clearly, the hind paws are much used in
digging, but most in swimming ;—the powerful hind leg, enor-
mous web foot, and strong claws, would prove this although no
one had ever seen the animal using them. Combine these
different actions of the fore and hind feet together and see what
would be the result. Suppose the animal swimming across its
pond or river with a burden of heavy materials clasped to its
breast by its fore paws, and powerfully propelled by its hind legs,
and that it had no tail or only a common tail—what must inevi-
tably be the consequence? The hind feet would propel the animal
rapidly enough—no doubt about that—but where to !—why, to
the bottom, for, being overloaded in front, it would be top heavy,
and its head becoming directed obliquely downwards the more
violent the exertions of the hind feet, the sooner it would reach
the bottom, and the deeper its head would be buried in the mud.
That this is the necessary and inevitable consequence of the
want of the action of the fore paws, will be evident to every one
if they will merely fancy what would be the result of their try-
ing to swim with their arms folded; of course, if there is not
only the inaction or abeyance of the fore arms to be conquered,
but also the weight of a load of mud or stones to be counteracted,
a counterpoising lever of more than ordinary power will be ne-

cessary, and this is supplied by the broad flat horizontal tail,
which is constructed on the best principles for attaining such
an object. Were it different or differently placed, the end would
not be answered; suppose it vertical like a fish’s tail, it would
answer equally well as a swimming organ, but not as a
counterpoise. It must be powerful, and it must be hori-
zontal, so as to press broadly downwards, and as the pur-
pose here is to increase resistance and friction, and not to di-
minish it, it is denuded of hair, or nearly so, and covered
with polygonal scales. A few scattered hairs occur, inter-
spersed between them, but these are not abraded as they
would have been had the tail been used as a trowel. That
this is the interpretation of the structure and purpose of the
tail igs I think self-evident from its fitness. The habit of
flapping the tail on the ground before plunging into the water
is probably only the mechanical repetition of the action with
which it habitually starts into motion, and which in the water
is essential to its progress.
The teeth of the beaver are often quoted as good examples
of the mode in which rodent teeth grow from the pulp at their
base, with a hard enamel-like steel on the outer edge, and
softer material on the inner side, and thus have their sharp-
ness and chisel-like form always kept up by the very thing
which at first sight would seem to be likely to make them
blunt—viz., their constant use. The incisor teeth in the
foetus are conical, thus showing that the chisel form in the
adult is the result of abrasion. The specimens sent me are
from the neighbourhood of Moose Factory.
I have adopted the specific name Americanus given to this
species by the Russian naturalist Brandt, who has separated
the American animal from the European and Asiatic (the true
Castor fiber) on osteological grounds, chiefly drawn from the
skull. For the reason alluded to above (want of specimens
for comparison), I can give no opinion as to the propriety of
this separation.
Mus leucopus, Rafin.—In his description of this species,
Sir John Richardson says,—‘ The tail is thickly clothed with
short hairs, lying pretty smoothly, no scales whatever being
Natural History of the Hudson’s Bay Territories. 25
visible.” In my specimen it is not thickly clothed with hairs ;
it is rather sparingly clothed with hairs, and the scales are very
apparent under them. He also says that “its” (the tail’s)
“upper surface is of a hair-brown colour, considerably darker
than any other part of the animal, and contrasts strongly with
the inferior surface, which is white.” The upper surface of
the tail in my individual is not nearly so dark as the back of
the body; still, however, as it agrees in all other respects with
Mus leucopus, I have no doubt that it is that species, and that
these differences are only accidental variations in my specimen.
SHREW-MOLE ? (Scalops Canadensis, Cuv.)—I have had no
opportunity of comparing this animal with any named speci-
mens, and my determination is made entirely from the descrip-
tion in Sir J. Richardson’s ‘“‘ Fauna Bor. Amer.” My specimen
agrees, for the most part, with the description in that work ;
but there are one or two points on which I am not quite
satisfied. In particular, the whole of the fore foot is said to
have a close resemblance to that of the common mole. Now,
although this has a general resemblance, it cannot be said to
bear a close resemblance. It wants the sabre-shaped bone of
the mole, and the nails are greatly smaller. The description
of the nails of the shrew-mole is, that they are large, white,
and have a semi-lanceolate form, with narrow, but rather ob-
tuse points. ‘These in my specimen can scarcely (according
to my ideas) be said to be large; but large is a word of very
doubtful interpretation ; what is large to one person may be
very small to another; so that, on this item, I must mark my
species with a query.
There is one point in the history of the shrew-mole which
I should like to see either confirmed or expunged from our
books—viz., that although a burrowing animal, it has the sin-
gular habit of coming daily to the surface exactly at noon.
Sorex parvus, Say.—This shrew may be readily distin-
guished from other American shrews by its tail being rounded
instead of being more or less angular. One might be disposed
to think that this is a character of little value, depending
merely on the greater or less plumpness of the individual; but

26 Proceedings of the Royal Physical Society.
it does not appear to be so, and other characters concur with
this to establish the species.
This one is certainly not well named; as, though un-
doubtedly a small animal, it is the largest of the North Ame-
rican species.
Sorex Forsteri, Rich.—The tail in this species is quad-
rangular. Itis the smallest quadruped known to the Indians ;
and I cannot call to mind any quadruped with which I am
acquainted, from any quarter of the world, which is smaller.
Among the specimens which have been sent me is one
which differs slightly from the description of S. Forsteri.
Its colour is wholly mouse-dun, whereas that of Forsteri is
wholly clove-brown on the back. The specimen is in spirits,
however ; and the clove-brown being, from what we see in
other specimens, a tinge of that colour in certain lights, it is
probable that the darker colour is merely owing to the medium
in which it has been sent; at all events, that the specimen is
at most only a variety.

viridis, which I had discovered some time before, together with
two other species, Lagotia hyalina and atro-purpurea:
The present species, Lagotia producta, was found in great
profusion in the tanks of Miss Gloag of Queensferry, in August
last, and resembles Lagotia viridis in its general characters.
It has the same long green body, surmounted by a horse-shoe-
shaped or two-pronged rotatory organ, each prong formed of
a membrane folded together, like the ear of a hare, and edged
by a muscular band fringed with vibratile cilia. It inhabits
also a similar flask-shaped cell, with bent neck and trumpet-
shaped mouth. But the body of Lagotia producta is greatly
prolonged in comparison with that of Lagotia viridis; the
colour nearly black, and the gullet a wide sac, and not a
spiral canal. In the present species, the neck of the cell has
become a long wide tube, greatly disproportionate to the flask-
shaped part from which it projects; the whole bearing some
resemblance to a long jack-boot. salon

IV. On the Danger of Hasty Generalization in Geology.
By Avexanper Bryson, Esq.
After deducing examples of hasty generalization, and show-
ing the frequency of erroneous conclusions drawn from scanty
data, he gave the following example, of which he was him-
self guilty :—“ In the summer of 1856, a few friends joined
me in a yachting expedition, to geologise among the islands of
the Firth. Among other islands we visited Inch Mickery,
and spent some hours in examining its structure. On the
southern summit of the rock, a quantity of lead was found,
filling up many of the interstices of the trap, which had, be-
sides, a very scorched appearance. This circumstance natu-
rally excited our curiosity, and many theories were formed
to unriddle the enigma, but in vain. We carefully examined
the island, but could not find a trace of a fire by which the
lead could have been melted, except at such a distance from
the rock as to render the idea of lead being carried so far
without cooling inadmissible. Then the lead had run into the
crevices of the rock, showing that it must have been very
fluid when it fell. The absence of every trace of carbon
around the lead, or at all near the rock itself, was very puz-
zling. About this time our talented member, Dr Heddle, had
announced the occurrence of native lead embedded in meteo-
ric iron, and I at once held my Inch Mickery lead as truly
meteoric in its origin. This idea was rendered the more
probable, as Dr George Wilson, who kindly analysed it, failed
to detect in it any trace of silver. Professor Fleming, al-
though he scouted the notion of its meteoric origin, kindly
accompanied us on a second visit to the island. After a per-
sonal examination, he was unable to throw any light on the
86 Proceedings of the Royal Physical Society.
subject, but advised us to wait patiently, and time might clear
up the mystery. We would have rejoiced had he lived to
learn the simple explanation only obtained a few months ago.
The Board of Fisheries some years since took it into their
heads that garvies were young herrings, and passed an act
forbidding nets to be used the meshes of which were smaller
than those employed in catching full-grown herrings. The
officers of the Board happening to detect a boat using the
illicit nets just off Inch Mickery, they, according to statute,
took the offending nets to this rocky knoll and burned them.
The leaden sinkers attached to the nets supplied my meteoric
lead, and the twine yielded sufficient fuel to fuse it.
V. Notes on some points in the Natural History of the West Coast of
Ross-shire. By Joun AtEex. Stewart, Esq., Lochcarron.
The first part of this paper was occupied with an inquiry into
the food and some points of the natural history of the limpet.
Besides the common species, Patella vulgata, Mr Stewart had
detected the finer species, P. athletica (which had hitherto
been chiefly found in the southern coasts of Britain), in
great abundance upon the coasts of Ross-shire and Skye. He
satisfactorily proved that the food of the common limpet
was not confined to sea-weeds, as was generally supposed,
but that it also fed upon Balani; and that the chief food
of the P. athletica was the Corallina officinalis. Wher-
ever that plant was in abundance, there A thletica was to be
found; and it was not confined to the low-water zone, as it is
said to be in the south of England. Mr Stewart described -
the process of feeding on the Balani and Corallina, and ex-
hibited specimens of the half-digested remains taken from their
stomachs. Mr Stewart also exhibited and described a species
of Comatula, which he considered different from the common
C.rosacea. He had, however, been anticipated in this disco-
very, Mr Barrett having published this species in the “ An-
nals of Natural History,” in 1857, under the name of Com-
matula Woodwardii. Mr Stewart farther exhibited a mag-
nificent Ophiura, new to Britain, which he had discovered in.
the same locality. It was 24 inches across, and differed mate-
rially from any even of the genera of this family hitherto found

in our seas. It belonged to the genus Asteronyz, described by
Muller and Troschell in their work on star-fishes. It seemed
doubtful whether it was the same species which they had de-
scribed under the name of A. Lovenii from Norway. In the
main, it very closely corresponded with their description, but
there were one or two discrepancies, which might either be
specific, or variations dependent upon the age of the animal.
Mr Stewart had only found one specimen; therefore, in the
meantime, he was not in a condition to give an opinion upon
this point. Mr Stewart, in conclusion, gave some interesting
notices regarding the pulsation of the snail as compared with
that of other animals; and also some notices of peculiar
geological features which he had observed in Ross-shire.

The following Communications were read :-—
I. Extract of Letter from the Rev. Hugh Goldie, Old Calabar, to Dr
Greville, respecting some singular Silk “ Bags” formed by Insects
in Africa. Communicated by W. H. Lows, M.D.
The following extract of the letter was read by Dr Lowe,
and specimens of the very curious ‘“ Bags” therein described
were exhibited :—
“Last year a brother of King Heyo undertook a trading
expedition to Efeet. [This is a country lying on the side of
the Camaroons Mountain, nearest the Old Calabar River.] In
the smaller box you will find something which he brought to
me as a curiosity, it being quite unknown in Calabar. The
articles are small bags, woven by what would appear to be an
insect of the same family as the silkworm. The insects are
said to form these on trees, many working at one bag; and,
having completed their task, each one rolls himself up in his
88 Proceedings of the Royal Physical Society.
own shroud and dies. The people of Efeet sometimes take a
number of insects and put them in one of their native pots,
when they commence to work, and line the interior of the pot
with their bag, by which means the people obtain large ones,
which they use to put cloth in, or any light article, and which
are said to be waterproof.”
Dr Lowe regretted that, while the objects were of themselves
of the highest interest, he was able to offer so little in the way
of information respecting them. ‘There was no doubt, how-
ever, that they were the production of lepidopterous insects,
and this belief was confirmed by Mr Andrew Murray, who
brought to the Society an excellent drawing of some bags ex-
tremely analogous to those exhibited, and which are known
to be the production of a gregarious butterfly in Mexico, a de-
scription of which, together with an illustrative plate, will be
found in the Transactions of the Entomological Society of
London, vol. i. p. 38, published in 1836. As one of the bags
from Africa was much. more dense in its texture than the
others, Dr Lowe was led to think that two species of insect
had been employed; but Mr Logan thought both might be
produced by the same butterfly or moth. Mr J. T. Syme
added some remarks ; and all the members joined in the hope
that specimens of the insect, in any state of transformation,
or however roughly preserved, might at a future time be pro-
cured by the kind agency of Mr Goldie.
II. A Series of recently-discovered Eyeless Beetles from the Caves of Car-
niola and Hungary were exhibited—By AnprEw Murray, Esq.
Mr Murray exhibited a fine series of eyeless beetles from the
various caverns, &c. where these curious and rare animals
have been found. There were twenty-six different species
shown, of which there were a number which had been only
discovered and described within the last two years, the pos-
session of which he owed to his friend Herr Dohrn of Stettin.
He pointed to the two new genera—Pholeuon and Drimeotus
—as being of special interest, as filling up a blank between
the genera of Leptoderus and Adelops, and proving that the
former of these genera truly belonged to the family of the
Cholevide, instead of being allied to the genus Mastigus, as

mentioned a number of interesting facts relating to the eco-
nomy and structure of these blind insects.
III. Notice of the Tenacity of Life mm Buecinum coronatum.
By AtexanpDER Bryson, Esq.
On the 6th September 1857 we reached Marseilles on our
way to Naples. Havinga full day to spend before the steamer
sailed, we drove to the Prado la Mer to search for shells on
the shores of the Mediterranean. On the sandy downs, close
by the margin of the sea, we found many Helices which were
new to us (Helix vermiculata, virgata), and others well
known to the south of Europe. They seemed very gregari-
ous, and we could collect them by handfulls. The shores of
the Mediterranean do not afford a fertile field for the concho-
logist, as the tides scarcely ever vary more than three feet.
We picked up a few Vatice, and also a specimen of Buccinum
coronatum, the tenacity of life in which is the object of this
notice. We placed the Buccinum along with our Helices,
and packed them all carefully in boxes, where they lay until
May 1858. On opening up the packages we found the Bucci-
num closely adherent to one of the Helices, but thought at the
time that it was dead. We threw them all into a basin of tepid
water, and found shortly that most of the Helices were alive, as
wasalso the Buccinum coronatum. We lost no time in placing
it in the marine aquarium of a friend, where he seemed quite
at home and lively. Unfortunately, however, in a few days
he came too near a hermit crab, who soon devoured the poor
Buccinum. The Helices lived in the conservatory for some
months, until the cold weather killed them. Ag this is the
first instance of which I have heard of the tenacity of life ex-
hibited by a marine molluse, I thought it should be recorded.
While we were strolling along the shores we saw a novel
method of fishing for sardines and anchovies. The fisherman
wades into the water nearly to the middle, and is furnished
with a large cireular net, round the periplery of which is
attached a series of leaden bullets. A long rope is attached
to the centre of the net, which he throws out in a very skilful
manner to the full extent of his line. The resistance of the

air and the centrifugal force causes the net to expand like a
flat old-fashioned umbrella, in which shape it reaches the
surface of the water. The weight of the bullets causes the
descent of the circumference, and the net assumes an oval
form, and the tiny fish are caught by the meshes in their
attempt to escape.
Mr Bryson also took the opportunity of reading the following
note he had received from his friend DrJames M‘Bain, R.N.:—
“ As an additional instance of the tenacity of life in cer-
tain species of the mollusca, I may mention that in the
spring of 1857 a small Helix was picked out from amongst
some dried raisins, and handed over to me by one of my fa-
mily. As it had the thin, transparent, glistening film cover-
ing the aperture, it occurred to me to repeat the experiment
related by Dr Baird, in reference to the Egyptian desert snail
in the British Museum, and included in the examples of
tenacity of life in these animals given by Mr Woodward in
his ‘Manual of the Mollusca.’ The following day our shy
friend made his appearance in the glass vessel, and lived with
us for five months. It was occasionally supplied with a little
water, and portions of green vegetables, such as cabbage and
lettuce, and seemed to give a preference to the latter. It was
precisely identical with specimens of Helix virgata got at
Shotover Hill, near Oxford, along with our friend Dr Mel-
ville in 1847. This species is widely spread over the south of
Europe, and, although having no objection to the interior,
yet, like ourselves, has also a strong attachment for the neigh-
bourhood of the sea. It is not surprising, therefore, to find it
in company with Malaga raisins; but those singular excep-
tions to the general laws, in the marked examples of torpidity
in various animals, living for indefinite periods without food,
and almost without air, are surprising.”

V. (1.) On the Vomer in Man and the Mammalia, and on the Sphenot-
dal Spongy Bones. By Joun Cretranp, M.D., Demonstrator of
Anatomy in the University of Edinburgh.
The remarks which I am about to make will be confined as
much as possible to matters of observation. I shall resist the
temptation to enter on the question of the constitution of the
92 Proceedings of the Royal Physical Society.
vomerine segment of the skull, although it is one on which
the statements to be made have an important bearing; I shall
content myself with exhibiting the relations of this bone in
different mammalia, and, founding upon these and on deve-
lopment, shall show how the vomer in man corresponds in its
relations to those of other animals, and what is the nature of
the sphenoidal spongy bones. .
Last autumn, while disarticulating the skull of a lamb, it
came prominently under my notice that the central plate of
the sphenoid bone adhered without marks of separation to the
presphenoid, while the lateral masses of the ethmoid and the
vomer formed one other single piece. On further examination
I found that in mammalian skulls the formation of one piece
by the vomer and lateral masses of the ethmoid was the gene-
ral rule, and their separation a rare exception. This isa cir-
cumstance so easily seen that one would think it could hardly
escape the notice of any one in the habit of disarticulating
mammalian skulls, yet I can find no description of it by
authorities on human and comparative anatomy. It is, how-
ever, as we shall see, the most important of all the connections
of the vomer, and throws some valuable light on human ana-
tomy. With respect to the other articulations of the vomer,
we shall see, that that with the central plate of the ethmoid is
by no means a primary one, and that the most constant of those
of its inferior margin is that with the intermaxillary bones.
In the ruminantia it is a well-developed elongated bone.
Let us take that of the lamb as an example. It consists
principally of two lamin united inferiorly so as to form a
groove; deepest posteriorly where the lamin are most de-
veloped, and shallowing away to a scooped extremity in front.
In this groove lies the cartilaginous septum of the nose, which
is continuous behind with the presphenoid bone. The pos-
terior extremity of the vomer is bifid and slightly dilated, as
it is in man, and in front of the dilatation the lines of mar-
gin begin to approach, and seem as if they would pass directly
forwards; but they are almost immediately lost as fissures in
two lateral expansions, which, springing from the vomerine
lamine, pass outwards to the outer and back part of the
ethmoid, and are continuous with the principal arches of the
On the Women in Man and the Mammalia. 93
framework of that bone. On the upper aspect there is a sharp
angle between the lamine that lie against the cartilaginous
septum and their lateral expansions, and the former are pro-
longed in many animals beyond the angle. Where the eth-
moid is joined by. the ethmo-vomerine lamina—for so we shall
call the expansion just described—it forms the upper part of
the nasal foramen of the palate bone, in human anatomy
called the spheno-palatine foramen. In the lamb there is not
much development of the vomer as a mesial plate below the
level of the groove. It articulates inferiorly by a rough
sutured edge with the superior maxillary bones, and in front
of that its scooped anterior extremity lies for about an eighth
of an inch or so on the groove formed by the mesial processes of
the intermaxillary bories—the universal method of articulation
of the mammalian vomer with the intermaxillary bones (fig. 1).
The vomer of the eat is proportionally less elongated than
that of the sheep, but like it has little development of the
mesial plate beneath the vomerine groove. It articulates by
a rough surface with the superior maxillary and palate bones,
but with the intermaxillary bones by an elongation forward
upon them of the laminze which bound the groove. These
laminze are connected towards their back part with the lateral
masses of the ethmoid, exactly as is the case in the sheep;
and at the point where the vomer passes into the ethmoid, the
latter presents a minute orbital surface, which les between
the two ascending processes of the palate bone, and completes
by a point in its inferior margin the almost perfect nasal
foramen of that bone. The sphenoid process of the palate-
bone lies between the ethmo-vomerine lamine and the ptery-
goid bone. The central plate of the ethmoid does not at all
touch the vomer in early life, but the cartilaginous septum of
the nose passes back beneath it to the presphenoid bone.
It may be mentioned at once that the nasal foramen of the
palate bone is completed by the ethmoid in all the animals
examined.
The relations of the vomer in the fow and the pig are the
same as in the cat. In the case of the hedgehog, as in the
sheep, it does not articulate with the palate bones. In the
horse also it does not articulate with the palate bones. But the
94 Proceedings of the Royal Physical Society.
superior connections of the vomer in the horse are peculiar,
inasmuch as the inferior surface of the leaflets of the ethmoid,
instead of lying in contact, as is usual, with the ethmo-vomerine
lamina for a considerable extent, is completely floored in by
the upper part of the palate bone, which is expanded for that
purpose. Even in the horse, however, a slender lamina, im-
mediately in front of the palate bone, and in contact with its
nasal foramen, passes downwards and inwards on each side
from the framework of the ethmoidal turbinations to the mar-
gin of the vomer; but the vomer and it are not anchylosed
until other sutures also have begun to be obliterated.
The vomer in the rodentia is remarkable in having very
little tendency to come in contact with the superior maxilla-
ries. As far as I have observed, it is always continuous with
the lateral masses of the ethmoid.
In the skull of the rabbit there is only one great anterior
palatine foramen ; for, although the mesial processes of the
intermaxillaries project well backwards, the palate plates of
the superior maxillaries do not come far enough forwards to
meet them. ‘The vomer does not at all approach the superior
maxillaries; its posterior margin terminates inferiorly»in a
thickened angle, which articulates with the intermaxillaries in
such a manner as to make their inferior aspect continuous with
the posterior margin of the vomer. In front of this, the lamine
bounding its groove are prolonged on the upper surface of the
intermaxillaries, as we have seen in other animals (fig. 4).
In the porcupine and squirrel the vomer is not in contact
with the superior maxillary bones; in the rat and the beaver
it 1s.
In the quadrumana the mesial process of the intermaxil-
laries is so slightly developed that the anterior extremity of
the vomer frequently falls short of it by a slightinterval. In
monkeys the vomer and orbital plates of the ethmoid are con-
tinuous; but in the skull of a young Chimpanzee in the Uni-
versity Museum, the arch of bone which unites them is sepa-
rated at one extremity from the ethmoid by a suture, and at
the other only touches the vomer. This piece of bone has all
the essential characters of the sphenoidal spongy bones of the
human subject.

On the Vomer in Man and the Mammalia. 95
The vomer and sphenoidal spongy bones in man.—Having
found the vomer and lateral masses of the ethmoid so univer-
sally connected, we naturally inquire how they are related in
man, They are not in contact. Their only connection is
that the expanded portion of the vomer which grasps the
rostrum lies beneath the sphenoidal spongy bones, and that
these articulate with the lateral masses of the ethmoid. Now,
seeing that the sphenoidal spongy bones are recognised as
ossifications distinct from the sphenoid, I think we have
already sufficient evidence to prove that they represent the
ethmo-vomerine lamin, by aid of what we have noticed in
the Chimpanzee’s skull; for it is impossible to doubt either
that the distinct bone which les between the orbital plates of
the ethmoid and the vomer in that skull corresponds to the
ethmo-vomerine lamina of other monkeys; or, on the other
hand, that it corresponds to the sphenoidal spongy bone in
man. But the correspondence becomes much more distinct
when we study the early condition of the sphenoidal spongy
bones. The most interesting condition of these bones is when,
in the skulls of young children, they can be got completely
ossified and not yet destroyed by amalgamation with the
neighbouring bones. In this state the sphenoidal spongy
bone is somewhat of the shape of a hollow pyramid with the
apex directed backwards, its inner aspect parallel to its fellow,
and its cavity (the first form of the sphenoidal sinus) opening
at its base into the nasal cavity in front (fig. 2). This pyramid
is constructed by the union of at least three distinct pieces of
bone. Firstly, there is an orbital piece, forming a portion of
the wall of the orbit between the ethmoid and sphenoid, an
element, I believe, in the formation of the orbital wall not
hitherto observed. It articulates with the orbital process of
the palate bone, and, together with the inferior piece, com-
pletes the nasal foramen of the palate-bone, namely, the fora-
men called spheno-palatine, but which we have seen to be
invariably ethmo-palatine in other animals. The superior
piece bounds the sphenoidal sinus above and on the inside,
and ultimately becomes incorporated with the sphenoid bone.
The inferior piece is the largest of the three; it forms the
floor of the sphenoidal sinus, and the under half of its opening

in front, and includes the greater part of what has hitherto
been recognised, and described under the various names,
sphenoidal spongy bone, sphenoidal cornu, and bone of Bertin.
Its inner margin is joined by the superior piece at an acute
angle, and is prolonged downwards and forwards so as to lie
edge to edge with the corresponding lamina of the vomer, im-
mediately in front of the thick dilated part of that bone.
Beneath and behind is the sphenoidal process of the palate-
bone, and behind that is the internal pterygoid process. In
man, therefore, as in other mammalia, we find three processes
in succession from behind forwards, viz., the pterygoid bone,
the sphenoidal process of the palate-bone, and an arch passing
from the ethmoid to the vomer, adapted to it edge to edge;
and moreover, this arch completes the foramen which divides
the ascending part of the palate-bone. It in every respect,
therefore, corresponds with the ethmo-vomerine lamina. The
reason why the arch formed by the vomer and ethmoid is
broken up in the human subject into so many separate pieces
is to be sought in the characteristic peculiarities of the human
subject, particularly in the very slight development of the
organ of smell, and the rapid curvature of the cranio-facial
arch. But on this subject I hope to speak more fully on sonte
future opportunity. The inferior edges of the sphenoidal
spongy bones, which in childhood he edge to edge with the
vomer, are in the adult state smoothed down to a mere ridge,
and considerably separated from the middle line by the ex-
pansion of the sphenoidal sinuses. ee
We have nowseen that the relations of thevomer to the lateral
masses of the ethmoid in the human subject are essentially the
same as in the mammalia generally. In early life the human
vomer resembles those of other mammals in form likewise, and
seems to be connected in the same manner with the intermaxil-_
lary bones. In the skulls of foetuses and young children the
vomer mainly consists of two lamine extending upwards on the
sides of the cartilaginous septum of the nose. The inferior edge
exhibits a flat surface with a raphe in the middle line, which
articulates with the superior maxillaries proper, i. e., with the
part behind the anterior palatine foramen ; and which narrows
to an edge behind, where it comes in contact with the palate-

bones. But this surface ceases abruptly in front, and only
the lamina bounding the groove for the cartilage is prolonged
on the intermaxillary part of the palate (fig. 3). In the adult
state both the scooped projection lying on the intermaxillaries,
and the remains of the surface for articulation with the supe-
rior maxillaries, can be seen, when the vomer still admits of
being accurately disarticulated. But this is not often, as it
soon becomes anchylosed with the neighbouring bones; and
even when this has not happened, it requires that portions of
the other bones be sacrificed for the sake of removing it en-
tire. As the face elongates, the upper part of the vomer
undergoes much alteration; not only is there a considerable
development of lamina in the mesial plane beneath the groove,
but usually the lamine bounding the groove deviate from the
mesial line, and one of them becomes more developed than the
other, and is more extensively anchylosed with the central
plate of the ethmoid, which, growing downwards, replaces the
cartilage between them. In consequence of these changes
taking place at a comparatively early period, the specimens
which are sold with disarticulated skulls, and from which the
descriptions in text-books are drawn up, are seldom complete,
and have most frequently more or less of the central plate of
the ethmoid adherent to them. Thus the vomer is described
as exhibiting at its upper and back part a cul-de-sac for the
rostrum. Such a cul-de-sac is often seen, but the central plate
of the ethmoid invariably enters into its formation, for it 1s
only the ethmoid, and never the vomer in the slightest degree,
which replaces the cartilaginous septum.

VI. On the Discovery of Nullipores (Calcarcous plants) and Sponges in
the Boulder Clay of Caithness. By Cuartes W. Peacu, Esq.,
Wick. (Specimens were exhibited.)
In a paper read to the Society in March 1855, “On the
Calcareous Zoophytes of the Boulder Clay of Caithness,” I
intimated that, at a future time, it was my intention to give
you one on the flora of that formation. I have delayed from
time to time, that I might search in wide localities, and thus
have succeeded in procuring several specimens at Wick, and
the burns of Haster and Freswick.* Mr Cleghorn has also.
found specimens at Wick, and Mr Dick in and around Thurso.
Although pretty widely distributed in the country, nowhere is
it found in abundance. At times it is quite soft when first
taken out of the clay ; it hardens on exposure, and cracks in
the drying, and then, should an attempt be made to make a
section, it crumbles to pieces. In one taken from the clay on
the side of Wick harbour I got a pretty good slice, and have
made out under the microscope the cellular structure ; it agrees
with that of the Melobesia polymorpha of Harvey, as may be
seen by the specimen herewith sent, mounted in Canada bal-
sam, and a specimen on stone, also from Wick. In one spe-
cimen, I noticed, as well as the spreading base, the papillary
eminences peculiar to this species; and in another the indenta-
tions made by saxicavous creatures. When passing Freswick

Burn on one of my official visits, 1 noticed the sections of
boulder clay exposed there; not having time then to devote
to their examination, I thought that, although fourteen miles
distant from Wick, I would try my pedestrian powers and do
so, on the day kept for the Queen’s birthday (1855), should
the weather prove fine. It did, and I was off early in the
morning, so that I might have a long search, not only in the
exposed sections of the boulder clay on my route, but every
quarry and place of interest. On searching the Burn of Fres-
wick, | commenced immediately at the bridge, and in the blue
clay there found several flints, evidently from the chalk,
hinges and portions of Cyprina, fragments of Turritella, Den-
- talia, &c., all more or less broken and rubbed. These were
firmly embedded, and so were all the specimens taken by me
from the boulder clay. After examining the sections above
the bridge, I retraced my steps, passed over the road and down
the burn towards the castle, and m a nice section worn by the
stream, as well as the usual stones, shells, &c., I met with a
white mass, which at first, from its yielding freely to the
knife, I thought chalk. After digging it out and washing it
in the stream, I was surprised to find that 2¢ would swim like
cork, and therefore could not be chalk. I put it carefully
into one of my boxes, and searched again, and at some distance
from the spot where I found the first | got a smaller piece of the
same description. They are the only pieces I have met with.
I have forwarded the smallest piece with this paper, enclosed
in glass, and hope that you will excuse my jealous care in
thus preserving the precious relic. As soon as I had fully
examined all the exposed clay, I turned my steps homeward,
wondering all the way what my swimming prize could be. As
soon as possible, after washing and taking my tea, I out with
a microscope, and placed a small portion of the mass under it,
when, to my delight, bundles of spicule, and quantities of
siliceous globules, were beautifully shown, as well as straight
spicula, triradiate, and other shapes; the spicula hollow in the
centre. I fancied it might be a Pachymatisma; but then
the stellate forms were absent. It effervesced freely in dilute
muriatic acid. In order to be set right, I forwarded a portion
of each piece to Mr Bowerbank of London, who, with his usual
100 Proceedings of the Royal Physical Society.
kindness, examined them, and informed me that they were
Geodia; the species he could not tell. He farther added,
“that he had found Geodia in a flint in the chalk; therefore
this sponge appears to be more ancient than had been sus-
pected.” We have Geodia zetlandica in our northern seas
(see Johnston’s “ British Sponges,” pl. ui., figs. 3 and 4, and
described at page 195). I also met with that species in Corn-
wall. The piece mounted in Canada balsam will show the
spicula and siliceous globules. Here, then, was a reward;
for not only did the walk of at least thirty-two miles prove
beneficial to the body—the mind truly enjoyed a feast; the
numberless objects of beauty that stud the path of the na-
turalist makes all roads cheerful; and if I were to add a list
of the attractions of that day, it would, though interesting, be
along one. It will be sufficient for me to say, that the excite-
ment caused by every new beauty drove weariness from the
body—mind triumphed over all—and to me this was a
“Queen’s day” indeed! The pleasure did not cease with the
day, for my collection of stores has given me much useful
employment since. Add to this, the satisfaction of knowing
that I had turned up a new leaf in the history of this long-
gone period. Long gone as it may be, its history is hnked
to the present; for the ancient organisms of the seas of the
clay period have direct descendants now living in our seas, and
although from our present knowledge some may be wanting,
either of the past or the present, the advancing march of re-
search is fast lessening the number, and filling up the gaps.
Geodia is not the only sponge from this formation which has
come under my notice, for in many fragments of sheils the
excavations of Clionia are frequent. 1 send portions of a
Cyprina and Buccinum burrowed by it. At present I have
seen only a single spiculum, the colouring, and probably very
minute portions of the sponge, and as well the peculiar small
indentations in the excavations. ‘“ These indentations,’ Mr
Hancock says, “are a very certain character which never
fails to determine the habitation of the burrowing sponge,
even though every particle of the animal be removed.” Un-
fortunately small fragments of shells only are met with ; these
have been so much rubbed and washed, that the delicate por-

tions have been destroyed; there 1s, however, no dowbt about
the genus. Many species “ existed during several geological
periods; for instance, in the Crag, in the London Clay, in the
Paris Basin, in the Chalk, in the Greensand, and in the Oolite.
Mr Alder has detected it in a specimen of Pecten islandicus
from a raised beach at Bute,” and to this list is now to be
added the boulder clay of Caithness. Many species of Clionia
also now exist in our seas, as shown in Mr Hancock’s delight-
ful paper, published in the 3d vol., second series, 1849, of the
« Annals and Magazine of Natural History,” from which the
above quotations were taken. I again beg to apologise for so
long delaying this paper. I trust that the additional matter
and facts collected by that delay will plead an excuse for me.
It is pleasant, when working in this once said to be barren
field, to be rewarded by adding to the shells of the age, first
zoophytes, and now sponges and plants.

KR. F. Ketaart, M.D. Communicated by Dr R. K, Grevitte.
In this paper the author states that he found in most of the

considered had much to do with the formation of pearls. This
worm he found in large numbers in the liver, ovary, mantle,
and other parts of the oyster. He also considered, from his
researches into the subject, that the ova of the oysters and
the ova of worms form the nuclei of many pearls found in the
soft parts of the animal, according to the doctrine of Sir
Everard Home. This theory has, however, been called in
question by many authors. Dr Kelaart had sent for examina-
tion specimens of ovaries, containing pearls of various sizes,
to the Museum of the Royal College of Surgeons, London,
which he considered tended to prove the truth of these views.
In pearls adherent to the shell he found the nuclei to he sand,
portions of sea-weed, and larve of insects, &c. In conclusion,
Dr Kelaart recommended that only the larger and more
matured oysters should be fished, and that portions of the
banks should be reserved for breeding purposes.
Mr Alexander Bryson believed pearls to be the result of
disease or of irritation, caused by the presence of foreign
bodies. He stated that, in all his experience, he had found a
nucleus of foreign and structureless matter, generally siliceous;
also, that he could, by examining the microscopic structure of
a pearl, at once infer what shell had produced it.
II. Note on the Lantern Fly of Honduras. By Mr James Banks.
Communicated by Dr J. A. SmitH.
At a previous meeting a specimen of the lantern fly (Ful-
gora laternaria) of Honduras, from Mr Banks, was exhibited,
and doubts having been cast on Madame Merian’s statements
as to its being really luminous at times or not, Mr Banks was
requested to get farther information, if possible, on the subject.
Dr Smith said he had been favoured with various letters, ex-
tracts of which were read. These Mr Banks had received from
correspondents in Belize, and they bore testimony to the truth
of the statement of this fly really emitting a light. One from
Mr Alex. Henderson, Belize, gives the following details :—
“In answer to the question ‘Is it really luminous? Cer-
tainly the fly possesses light, and therefore emits it. The
light is evidently under its control, for it increases and dimi-
nishes it at pleasure. When the wings are closed, there are.
Note on the Lantern Fly of Honduras. 103
three luminous spots, one on each side of the head part, on the
upper part (like a cat’s staring eyes), of a beautiful sulphur-
coloured light, in rays that spread over the room. ‘The third
luminous spot is seen when the fly is on its back, half way
down the abdominal part of the insect. When quiescent, the
lumination is least ; in daylight the upper spots are nearly
white, emitting no light whatever (its lively time is at twi-
light). Immediately on being agitated, or moving about, the
spots become sulphur colour, and radiate forth streams of light,
clearly seen, although the sun be shining into the room, as it
now does at the moment I write, with the creature in the glass
tumbler before me. We put out the lights, and to test the
power of the fly, I took up my psalm-book and read two verses
of Psalm cix. Mr Robert Gegg also took up a book at random,
and read by its light. I hope this will satisfy all that the
lantern-fly is indeed luminous.” He had also a letter from
Dr John Young, Belize, kindly offering to make any observa-
tions the Society might desire. A published statement, in
the “History of the West Indies,” by R. M. Martin, 1837,
vol. 11. p. 104, being vol. v. of British Colonial Library, corro-
borating the truth of the lantern-fly being luminous, was also
referred to.
Ill. (1.) Notice of a Fossil] Nautilus from the Isle of Sheppy. By
James M‘Barn, M.D., R.N.
Dr M‘Bain said, that the specimen of a fossil nautilus which
he exhibited to the Society was obtained from the Isle of
Sheppy, along with other fossil remains, and presented to
him by his friend Dr Easton, of H.M.S. Pembroke. Before
placing the specimen in the public museum of Edinburgh,
which, under the present energetic management, was rapidly as-
suming a highly scientific character, he considered it advisable
to give a short description of the state of preservation of the
shell, and the locality whence it was derived. The species
agreed with the description of the Nautilus Sowerbyi, given
in a monograph of the Hocene Mollusea, by F. E. Edwards, and
published by the Paleontographical Society. The specimen
he exhibited was seven inches in diameter by four inches
across, measured from one umbilical space to the other. It

had lost the whole of the outer or inhabited chamber, but the
triangular shape of the aperture was distinctly shown by the
compressed ventral margin of the remaining part of the shell.
The position of the siphuncle—said to be close to the dorsal
margin—seemed to be indicated by a small deposit of iron
pyrites, probably caused by the organic matter having been
longer retained in that canal. The interior of the shell was
filled with a ferruginous clay, containing a large proportion of
carbonate of lime, a stalagmitic layer of which was seen en-
crusting a portion of the mass. Defoliation of the outer
porcellanous coat of the shell had taken place, but what
remained of the inner nacreous layer showed the strie of
srowth bending sharply backwards in well-marked undula-
tions. If the proportions of the fossil specimen were similar
to those of the recent Nautilus pompilius, the shell, when
entire, would have measured about fifteen inches in diameter.
Dr M‘Bain stated that the Nautilide were in some respects
the most interesting family in the molluscan sub-kingdom.
They formed the type of the second order, Tetrabranchiata of
Owen, in the class Cephalopada, of which upwards of 1400
fossil species have been disinterred from the Paleozoic and
Mesozoic rocks. Of all the genera constituting the Tetra-
branchiate order of mollusca that existed in the ancient seas,
the nautilus was the only one that had been found to pass into
the tertiary formations, and there were at least two species
still existing in the seas of the tropics. Six fossil nautili
were stated by Mr Edwards to have been found in the older
Eocene deposits of England, and four of these had been ob-
tained from Sheppy—the WV. centralis, NV. urbanus, N. impe-
rialis, and NV. Sowerbyi. That island was well known to
paleontologists as a rich depository of organie remains. It
was situated on the south side, at the mouth of the Thames,
and separated from the county of Kent by the East Swale,
and estuary of the river Medway. The greatest length of
the island, from the garrison at Sheerness to Warden Point,
the easternmost extremity, was about ten miles, and it was
from five to six miles in breadth. The geological structure
consisted of a vast deposit of dark gray or brownish clay,
rising to the height of nearly 500 feet above the sea, with
Notice of a Fossil Nautilus from the Isle of Sheppy. 105
interstratified layers of concretionary nodules, commonly
called septaria or cement stones. This clay belonged to the
lower tertiary formation, and formed a part of the London
basin—one of those isolated fluvio-marine deposits which took
place in hollows of the chalk subsequent to the cretaceous
epoch. On the north side of the island, and eastward from
Sheerness, the cliffs rise to the height of from one to two
hundred feet, and, chiefly from atmospherical causes, were
constantly crumbling down in large prismatic masses, which
gradually broke up, and formed a flat shore of fine silt. Mud
banks extended off shore for about half a mile, and at low
water workmen were employed in procuring the cement stones.
The beach was not more than from ten to twenty yards wide,
on which were strewed abundance of fossil fruits, wood, crus-
tacea, and mollusca, which had fallen out of the clay. Dr
M‘Bain said, he had frequently obtained upwards of a hundred
. Hocene fossils in a single excursion, and that the remains of
fish and reptilia were also of frequent occurrence in the Lon-
don clay of the Island of Sheppy. He added, that many of
these Hocene fossils became mixed with recent organisms, and
were buried together in the re-composed silt, which the hasty
generalization of some paleontologist, in a future new geolo-
gical epoch, might consider as a sufiicient proof that they also
lived together at the same time in the Cainozoic period.
(2.) Notice of the Nucula decussata, found in the so-called Raised Sea-
beach Bed at Lett). By James M‘Bain, M.D., R.N.
The members of the Society, Dr M‘Bain said, were no
doubt familiar with a bed of sand and gravel extending along
the shores of the Forth in a more or less continuous manner,
and generally known as the raised sea-beach bed. This de-
posit had been considered by several eminent geologists to re-
present an ancient sea-beach, which, in consequence of a gene-
ral elevation of the land, had been raised twenty feet or more
above the level of the sea, at a comparatively recent geologi-
cal period. This view was strenuously opposed by the late
Professor John Fleming, who maintained that this so-called
raised sea-beach bed and other accumulations of a similar

structure, at still higher levels, derived their origin from
“ground storms” or sudden risings of the sea, by which shells,
sand, and gravel, had been placed in situations now consider-
ably removed from the influence of the tide. Professor Flem-
ing had arrived at this conclusion as early as 1806, from ex-
amining a bed of shells, chiefly composed of the common
oyster shell, to the westward of the town of Borrowstounness,
in the county of Linlithgow, and stretching along the banks
of the Forth into Stirlingshire. The raised sea-beach contro-
versy forms nearly the whole of the last chapter of his last
work—‘“ The Lithology of Edinburgh.” Any new fact, there-
fore, connected with this distinct marine deposit would be of
interest. This raised sea-beach bed is well exposed in many
parts of the coast between the sandstone quarry at Granton
and the Magdalen Burn near Fisherrow. It varies in thick-
ness from two to ten feet, and contains abundance of com-
minuted shells, with many in a more or less perfect state
of preservation. The horizontal position of the bed in re-
spect to the present high-water level is by no means equal.
At Granton quarry, the base of the bed is about ten or twelve
feet above high-water mark, and rests upon the sandstone and
boulder clay; whereas a quarter of a mile to the eastward, at
a ledge of rocks projecting sea-ward, 1t is only two or three
feet above high-water level. The bed is then interrupted by
a sea-wall, until at the east end of the village of Newhaven.
at the collection of boulders that form a boat harbour, it is
again observed nearly on a level with high-water.
From this point eastward the bed gradually rises in height,
and at an interesting geological section of the boulder clay
called the Man-trap, the base of the bed is seen to rest on the
clay, 15 feet above the high-water line. Itis then lost sight
of by the sea-wall in front of the artillery barracks; but Dr
M‘Bain had lately an opportunity of seeing it exposed in a
digging for a drain, at the north end of Albany Street, where
it appeared about seven or eight feet above high-water.
Nearly in a line with this digging, and south of the road op-
posite the west end of Leith Docks, a foundation for a large
building was begun a month or two ago; and in watching the
progress of the work, after the removal of two or three feet

of artificial soil, the continuation of the sand and gravel bed
was observed to cover the boulder clay at six or eight feet
above high-water level. In a section made for the foundation
of the east wall of the building, the boulder clay was cut down
to the depth of 12 or 14 feet; and in the sand and gravel-bed
overlying the clay at this part, amongst other shells usually
found in this bed, a detached right valve of a Nucula was
obtained, having the sculpture and characters of Nucula de-
cussata. The epidermis was well preserved, and of an olive-
green colour. It was marked with concentric wrinkles, and
strongly raised radiating strize, with short but distinct trans-
verse plice on the dorsal area. The inner surface was pearly
white, and had a crenulated margin, with twelve pectinated
teeth in front of the cartilage-depression, and about double
that number behind. The valve was rather more elongated,
and larger than the ordinary examples of the common Nucula
nucleus.
The WV. decussata is not recorded as having been found in
the Firth of Forth, but it lives on the west coast of Scotland,
and in the Hebrides, and is said by Liven to be a Swedish
shell. The specimen was accidentally broken, and the fact of
the valve having been found is only recorded to direct atten-
tion to a closer scrutiny of the marine contents of this depo-
sit, especially in sections inland from the present high-water
level ; as the lateral extent of this so-called raised sea-beach
bed, and its relation to other accumulations of a similar litho-
logical structure, but destitute of any trace of marine remains,
had not been satisfactorily determined.

V. On a Method of constructing Polarizing Prisms of Nitrate of
Potash. By T. Strernint Wricut, M.D.
Dr Wright stated that many doubly-refracting substances,
when immersed in dense and transparent fluids, had, as was
well known, the property of polarizing light. This polariza-
108 Proceedings of the Royal Physical Society.
tion of light was not effected by the whole surface of the sub-
stance, but only by inclined parts of it which intersected the
ray in an oblique direction. In passing through such parts a
beam of light was divided into two rays polarized in opposite
planes. The one ray continued its original course, while the
other suffered deflection proportionate to the inclination of the
polarizing surface, and was thus entirely thrown out of the
field of view. It occurred to the author that large crystals,
having their surface artificially inclined, might, when 1m-
mersed in a highly refractive fluid, be used as polarizing
prisms, and he had succeeded in thus forming polarizers, one
of which he placed before the Society, and which was found
to be well adapted for application to the microscope. It con-
sisted simply of a wedge of nitrate of potash, cut from one of
the angles of a large crystal, and put up in a cell filled with
eastor oil.
Dr Wright stated that very beautiful objects for the polari-
scope might be formed of clear plates cut from the surfaces of
large erystals of nitre, and grooved in various designs. These,
mounted on a colouring plate of mica, and enclosed im a plate-
glass cell filled with oil of turpentine, gave rich effects of
changing tint when traversed by light reflected from a glass
plate or from the northern sky. Large planes of parallel
polarizing crystals might be produced by crystallizing muriate
of morphia on shghtly inclined plates of glass, and might be
removed so as to leave designs. These figures, when mounted
in Canada balsam, with colouring plates of mica, gave curiously
dazzling binocular effects, or when viewed with both eyes, as
the two images differed in colour for each eye. In examining
objects of this class. 1 was necessary to stop off all rays but
those passing at right angles to the polarising plate.
VI. Notes on the Geology of Swellendam, South Africa. By Wittiam
Carrutuers, Esq. (Specimens of the rocks and fossils were ex-
hibited.)
The specimens which formed the subject of this notice were
gathered and sent to this country by Mr Robert Douglas, a
self-educated and enthusiastic geologist. They were intended,

the author said, for his late friend, Mr James Brown, a young
chemist, who, by his labours and discoveries in the science to
which he had devoted himself, gave promise of an active and
useful life, which was, however, cut short by an attack of
cholera, that in a few hours proved fatal. His retiring manners
and devotion to his work made him unknown, save to a few
friends, who were thus unexpectedly called to mourn the loss of
one who seemed destined by his labours to command the respect
of the scientific world; and the collection was some months
ago placed in the hands of the writer by his father. It con-
sists of nearly 1000 different specimens, with accompanying
manuscripts, drawings, and sections, most elaborately exe-
cuted. Valuable memoirs had been published by Mr Bain on
the geology of South Africa; but he did not seem to have
visited Du Toit, the locality where the fossils on the Society’s
table had been gathered, as it was not mentioned by him.
Du Toit is about thirty-five miles north-west from Swellen-
dam. It is situated on the further side of the Lange Bergen
Mountains, on the oldest beds of what, from paleontographical
evidence, seems to be the Old Red Sandstone. The fossili-
ferous beds are composed of coarse sandstones and shales.
The fossils are chiefly brachiopod mollusea, and include
Spirifer antarcticus, and Orbignit, Terebratula Bainii, Orbi-
cula Bainii, &c., Solinella -antiqua, and other bivalves.
Besides these there were only some Enerinite stems, and the
cast of a Trilobite, neither of which could be more specifically
described, owing to their bad preservation. Mr Carruthers
noticed the remarkable condition in which the clay slates of
the metamorphic series exist in the vicinity of Swellendam,
where they have little more consistency than dried alluvial
brick clays, so soft as to have permitted Mr Bain to drive a
tunnel of 400 feet through them by the aid of the pickaxe and
spade alone. The induration increases, however, until in
other localities the rocks become, as Mr Douglas says, “ ex-
ceedingly hard, siliceous, and splintery, so as to cut the hand
when incautiously griped.”

VIL. Ornithological Notes. (Specimens were exhibited )
(1.) The Gadwall, Anas strepera, Linn. By P. A. Dassavvitte, Esq.
This species being of rare occurrence in Scotland, Mr
Dassauville thought it might be of interest to show the two
specimens now before the Society. They were shot on the Tay,
near Newburgh,.1n the beginning of April, and are a male ana
female, as was proved by dissection, the ova of the female being
numerous, but not far advanced. Mr Dassauville was aware
of the danger that specimens obtained, as these were, in the
_ poulterers’ shops, might not be actually procured in this
country, since importing wild fowl from the continent was
so general; but the specimens under notice were evidently
so recently shot—the feet and webs being quite soft and
flexible—that he had no hesitation in believing they were
killed in this country, without other evidence; however, he
had been obliged with a sight of the invoice which accom-
panied them, dated from Perth, and felt satisfied there was no
room to doubt that they were procured from the locality men-
tioned. One or two sessions ago Dr J. A. Smith exhibited
to the Society specimens-of the gadwall, and these were the
only others he had seen that were killed in Scotland.
(2.) The Shoveller, Anas clypeata, Linn.; the Great Grey Shrike,
Lanius excubitor, Linn.; the Shore Lark, Alanda alpestris, Linn.
By Joun ALEXANDER Situ, M.D.
Dr Smith said, he was disappointed in not being able to
exhibit a very fine pair of Shovellers (Anas clypeata), male
and female, which he had examined; they were shot near
Kincardine, on the Forth, about the Ist of April. The birds
were now the property of Robert Chambers, jun., Esq., and
as they were rare in this neighbourhood, their capture was
worth putting on record. He exhibited an adult male Cine-
rious Shrike, Zanius excubitor, which was one of our occa-
sional visitors, and far from common ; it was noticed to occur
generally in the beginning of winter. This bird was got on
the 30th of March at Tulliallan, near Kincardine, on the
Forth. Mr James Miller, the gamekeeper who shot it, had
Notes on the Crania of the Bos primigenius. 111
never seen a specimen of the bird before, although he had
lived for many years in the district.
The last bird Dr Smith had to notice was the Shore Lark,
Alauda alpestris, Linn. It is a bird of very rare occurrence,
being apparently only an accidental straggler in this country ;
in the north of Asia, Europe, and especially America, it
abounds, and migrates southwards in the autumn to more
temperate regions. The first specimen noticed in England
was in 1830, and only one or two have been observed since.
He had not been able to find any recorded as taken in Scotland.
This bird was killed by Mr Evans, Tynefield, about the 10th
of January last, near the mouth of the Tyne, and its plumage
was unfortunately much destroyed by the shot. Itisa fine old
male, having the back brown; tinted on the head, neck, and
shoulders, of a rich vinaceous colour; the streak over the eye,
the forehead, and the ear-coverts, yellow; and with the lore
and a gorget of black; under parts dull white, and flanks pale
reddish brown; axillaries white. It is the property of Dr C.
Nelson, Pitcox, near Dunbar, to whom it was presented.
VIII. Notes on the Crania of the Urus (Bos primigenius) in the
Museum of the Society of Antiquaries of Scotland. By Joun
ALEXANDER SmitH, M.D.
Some years ago, when gathering up various details in refer-
ence to the ancient small short-horned cattle of this country,
my attention was also directed to the large cattle (Bos pri-
migenius), and to the specimens of crania in the Museum of
the Society of Antiquaries. I took various measurements of
these crania, and searched the early records of the Society
for such information in regard to the places where they were
found, and any other details that might be of interest; and
as Mr ‘Turner has favoured us this session with some details
of the specimens of this great ox in the Anatomical Museum
of the University, I have thought it might interest the mem-
bers if I produced my old notes on the subject.
There are three specimens of these crania of the Bos primi-
genius in the Museum of the Society, marked Nos. 2, 4, and
5 of the “ Fossil Skulls,” &c., in the printed Catalogue of the
Museum, and the following table gives some of their measure-
ments :—

The cranium No. 4 was the one first presented to the
Museum of the Society, by the Rev. Thomas Robertson,
minister of Selkirk, in 1781. The donation was made through
a Mr Cairncross, and the following letter accompanying it is
preserved in the library of the Society :—
~~
To Mr George Cairncross, Writer, Parliament Close,
Edinburgh (with an ox's skull and flints).
SELKIRK, July 14th, 1781.
“ DEAR StR—Among other curiosities dug out of a marle
moss at Whitmuirhall in this parish, the skull and flints of
an ox which I have sent you attracted my attention. You, I
know, are fond of anything that tends to throw light upon the
ancient state of this country, and therefore I used the freedom
to transmit this, not merely on account of its uncommon size,
but as a proof of the large breed of cattle with which this
country abounded in the last century. I found five skulls,
evidently larger, but not so entire. I found also several small
axes, resembling those used by coppersmiths, but did not

think it worth while to trouble you with them. If anything
deserving the attention of your Society occurs in this part
of the country, I shall assuredly transmit it to you. Mrs
Robertson joins me in best compliments to Mrs Cairncross
and the family—with, dear Sir, your humble servant,—
Tuomas Ropertson.—First Letter-book of Soc. Ant. Scot.,
p. 628.
The skull was presented to the Society at its meeting on
the 17th July 1781; and the following reference to it is re-
corded in the Minute-book, vol. 1., p. 72:—
“ Mr George Cairncross presented, from the Rev. Thomas
Robertson of Selkirk, the bones of the head and flints of
the horns of a large animal dug out of a marle-pit near Sel-
kirk, at a place called Whitmuirhall. The circumference of
each flint at the base is 143 inches; the length of that on the
right 27 inches, of the other 28 inches; the distance between
the sockets of the eyes 114 inches; the breadth of the front,
which is quite flat, from the sides immediately over the sockets
of the eyes, 124 inches; the depth from the top of the front
to the top of the sockets of the eyes, 10 inches; and from the
top of the front to the upper part of the insertion of the car-
tilage of the nose 13 inches. This appears to be the animal
described by Julius Cesar in his “‘ Commentaries,” Book vi.
c. 5, by the name of Urus.” And the Secretary, Mr James
Cumming, in a letter dated 25th July, informs the Rev. Mr
Robertson that the skull was presented to the Society, and
‘in the opinion of some able naturalists among us, it is
believed to belong to that species of animal described by
Julius Cesar in his ‘Commentaries,’ Lib. vi. c. 5, by the
name of Urus.”
The cranium No. 2 is tolerably entire, but, like all the
others, the lower jaw is awanting. It was dug out of a moss
in the county of Galloway, and was presented to the Museum
of the Society by the Rev. David M‘Robert, in the year 1782.
In this cranium two of the molars remain in the alveolar
sockets. Itis referred to in the Minute-book, p. 205, July
12, 1782, as follows :—
“There was presented, from the Rev. David M‘Robert, the

skeleton of the head and flints of the horns of a large animal
dug out of a moss in the county of Galloway, similar in species
to the one described in page 72, paragr. ult., and nearly of the
same dimensions; the whole length of the front measuring
2 feet 2 inches ; two of the Dentes molares remaining in the
upper jaw, each having one deep furrow in the middle, and
measuring on the under surface 14 inch the one way, and
% of an inch the other.” No letter relating to this skull
seems to have been preserved, as, unfortunately, a gap occurs
in the letter-books at this period; and from ‘the same reason
we learn nothing of the last specimen presented, No. 3, except
what is stated in the Minute-book, July 9th, 1782, p. 220:
—‘‘There was. presented from Thomas Scott of Hapsburn,
Esq., the skeleton of the head and flints of the horns of a large
animal similar in species to the one described in page 72,
par. ult., and in page 205, paragr. 4, and nearly of the.same
dimensions, but more entire than either; the whole length of
the front measuring 2 feet 4 inches, four of the Dentes
molares remaining in each side of the upper jaw, of the same
size and shape with those in the head described in page 205.”
As far as I am aware, these are the earliest instances on
record of this large-sized ox being observed in Scotland, and
it is interesting to find the conclusions come ’to in regard to
them by the naturalists of this generation forestalled by a
small body of quiet students of the Antiquities and Natural
History of Scotland meeting in Edinburgh so early as 1781;
identifying these large cattle as being the same as the URwus,
the gigantic ox described as occurring on the continent of
Europe, by Julius Cesar, in his “ De Bello Gallico.” I need
scarcely refer to the mistake made by the Minister of Selkirk
in his letter accompanying the first donation, that they were
the remains of cattle of what he calls the “last century.” The
general opinion has been that they were extirpated in Britain
before the invasion of the Romans, as historians are altogether
silent on the subject of their existence. They had, however,
apparently abounded, at least in Scotland, probably at a some-
what more early period, which seems to be shown by another
part of Mr Robertson’s letter, where he refers to various small
brass axes being found along with the numerous crania of
Notes on the Orania of the Bos primigenius. {115
these large cattle. Unfortunately he considered thése axes
as of very little consequence, from some supposed similarity
to the tools of coppersmiths, though what work coppersmiths
could have had to do in the wilds of Selkirkshire, so as to
have left their axes lying about in such numbers, it is not
very easy to understand. He apparently mistook the nature
of these weapons, which were in all likelihood the ordinary
bronze axe-heads or celts, now so well known as having been
the weapons and tools of the early races who inhabited the Bri-
tish Isles, and which have been found over the whole country,
as well as in the stone cists the tombs of the ancient people.
I exhibit various specimens of these bronze celts, palstaves,
and socketed celts, which, I doubt not, correspond to the
coppersmith’s axes of the letter referred to. The accom-
panying woodcut shows various types of these axes.
It has been stated, that bones of the Bos primigenius
have been found indented with the primitive stone javelin of
the aborigines of the north of Europe; here we apparently
have them in close relation to the bronze weapons of a possibly
still later age, showing that these animals roamed in our forests
and marshes, and were hunted by the inhabitants of these
early times in at least our northern kingdom of Scotland.
Professor Owen says, “from the very recent character of the
osseous substances in the remains of these cattle, it may be
concluded that the Bos primigenius maintained its ground
116 Proceedings of the Royul Physical Society.
longest ‘in Scotland before its final extinction. And Pro-
fessor Nilssen of Lund believes that the Bos primigenius was
found in a wild or half-wild state in the forests of central
Europe down even to the beginning or middle of the sixteenth
century. (See papers on the Extinct and Existing Animals
of Scandinavia,” in “Annals and Magazine of Natural
History,” 1849.)
Dr J. A. Smith exhibited the skull of a sheep (a wether)
which, from the singular variety in the form of its horns, had
been sent by Mr Sanderson, bird-stuffer, George Street. The
horns were closely adjoming each other at the base, in the
centre of the forehead, as in the buffalo, and from this point
they were bent outwards and upwards like those of the ox.
The Society then adjourned to next winter session.

Anprew Murray, Esq., President, then delivered the Opening Ad-
dress, as follows :—
GENTLEMEN,—It is the custom of this, as of most other
Societies, to open the business of the session with an address
from one of their Presidents; and our rule is that this duty
shall be performed by the senior President on the occasion of
his retiring from office, it so happening that the terminal
period of that office coincides with the commencement of our
session. The term for which I was elected President now
draws to a close; I am about to lay down the honour with
which you invested me; and the duty of addressing you on
VOL. II. Q
118 Proceedings of the Royal Physical Society.
the present occasion therefore devolves upon me. The occa-
sion, although an opening one as regards you, being thus a
closing one as regards me, naturally suggests that the subject
of my address should be of a retrospective nature; and so it
has usually been considered by my predecessors in this office.
The kind of retrospection, however, which of late years has
formed the subject of their addresses, has, alas! almost exclu-
sively been the funeral orations of eminent members removed
from us by death during the previous year. Year after year
death has gone on picking one by one the best (though not
always the ripest) fruit from among us. One year it was
Edward Forbes; the next year it was Hugh Miller; the year
after, Dr Fleming; and it was clear that no President would
have well fulfilled his duty who, in his address, had passed
over the deaths of such eminent members of our body without
a suitable record and eloge. Owing to the importance of these
losses, this species of retrospection has necessarily been pre-
vented from falling into arrear. And now, when, thanks be
to God, we have had a momentary respite, and have passed
over another year without having such another limb lopped
off, the President of the day can turn to another kind of
retrospection, which has fallen into arrear, or, I should rather
say, which has never, since the revival of the Society, been
begun to be brought up. Not that we have no losses during
the past year to deplore, but that those which have been
sustained are of members who, however able and regretted by
us all, have not occupied that space in the public eye, nor
achieved that amount of eminence in science which distin-
guished the members whose names I have just mentioned.
Thus had I written, gentlemen, when, on entering this room,
I find my congratulations dashed to the ground by the melan-
choly intelligence of the death of Professor George Wilson,
which has just been communicated to me. Although not now
one of our working members, we cannot forget that Professor
Wilson was formerly one of our Presidents, and that of late
he has been one of the foremost men in our scientific world in
Edinburgh. The loss will be felt both as a public and a
private one. His genial and amiable disposition endeared
him to his friends and acquaintances; his abilities and attain-

ments secured the regard and admiration of the public. The
direction in which these have been exercised of late years lay
more peculiarly in the walks followed by other societies,
which he more frequently honoured by his presence and
valuable contributions, and by them his loss will be more
severely felt, and from them we may look more fittingly for a
narration of his life and labours. To them I will leave it then,
and at once proceed with what I was about to say regarding
a summary or view of the progress made during the previous
year or years in the sciences cultivated by the Society. The
desirableness of such periodical reviews or reports will not be
disputed; and the general persuasion entertained of their
value is sufficiently indicated by three-fourths of the annual
Presidential addresses professedly aiming at giving such
reviews. And yet the practical results of such attempts are
far less satisfactory than might be expected. The student of
any department of science might naturally expect that, by
referring to an address of this nature, he would find a resumé
or abridgment of the most important work that had been
done in that department during the previous year. But he
will generally find himself disappointed; he will find refer-
ences to such proceedings and discoveries as he already
knows, but seldom to much beyond this. And the reason of it
is this: the scope of the address is usually too wide; it
embraces too much; and as the writer cannot omit notice of
the main discoveries which have been the ornament of the
year, by the time he has gone over these his space is ex-
hausted, and more minute details are impossible. It is only
in societies having a very restricted, single, and direct object,
that it can be possible to give a comprehensive summary of
all the progress made during the past year. In a society
embracing so many, so large, and so well-laboured fields as
this does, it would obviously be impossible to compress into a
single address (even supposing any one individual were com-
petent to do so), a full or satisfactory resumé of the progress
of the sciences in which we are interested during any one
year. It has, however, been suggested to me by our excel-
lent Secretary, that a less ambitious attempt might be more
within reach of success; and that, by restricting the field
120 Proceedings of the Royal Physical Society.
of operations, a more useful, in so far as a more complete,
review might be given. In this Society, although we are
all bound by a common bond of union, and all feel an in-
terest in every one of the departments of science which are
treated of here, we are not equally proficient in them all.
Each has usually some particular branch of our common study
in which he feels a greater interest than in the rest. Each
has made greater progress in the knowledge of some one
special department ; and without in any way depreciating the
extent and the value of his general knowledge of the whole,
each 1s undoubtedly better qualified to give a review or sum-
mary of the progress of that branch with which he is him-
self most familiar. It has been suggested to me, then, that if
those of our Presidents who in their address should wish to
cast a retrospective glance over the progress of science were
to confine themselves to a report upon the branch with which
they are most familiar, we should in the course of a few years
have a series of summaries which might be really practically
useful to the student—at all events, more so than any merely
general retrospects could possibly be. In my present address
I propose to act upon this principle ; and taking that branch of
science, Entomology, which is my favourite department, and
that branch of it (Coleoptera) which I specially affect, I shall
endeavour to lay before you a view of what has recently been
done in this science, both at home and abroad :— |
Beginning with the works on systematic entomology published during
the last three years or so, facile princeps, whether in extent and import-
ance of subject, or in the mode in which it is executed, stands Lacordaire’s
Histoire des Genres des Coleoptéres,—a work now in course of being pub-
lished as one of the Suites d Buffon. For a long series of years, ever
since the days of Fabricius, Latreille, Olivier, &c., when the whole number
of insects known did not exceed many hundreds, down to the present
day, when 100,000 species but faintly represent the number actually known
(there are 90,000 species of insects of all orders in the Berlin Museum), en-
tomology has been going on constantly increasing, without any systematic
work or general treatise upon it having been executed. An enormous
number of species have been separately described in transactions ar
periodicals ; numerous combined descriptions of new species peculiar to
individual districts have been published; and also a number of local
faunas, such as those of Hrichson, Stephens, Redtenbacher, Mulsant, Heer,
Rossi, &c. Many most valuable monographs and treatises upon special
groups of Coleoptera have also been executed, such as Dejean’s Carabide,
Aubé’s Hydrocantharide, Erichson’s Staphylinide, Burmeister’s Lamel-
licornes, Schonherr’s Curculionidae, and a host of others. To attempt to
lick these into shape—to throw them all into one common systematic

treatise, embodying at their proper places the thousands of independent
notices scattered through a crowd of transactions and periodicals—dispos-
ing of questions of disputed synonymy—deciding the great questions of
disputed arrangement, and where these appear wrong correcting them,
or offering a new solution of the difficulty,—is a task requiring the pa-
tience of Sisyphus and the powers of labour of Hercules, combined with
talents, attainments, and facilities possessed by very few. Such is the
task which is now being successfully carried out by Professor Lacordaire.
Five volumes have already appeared: the first is occupied with the
Carabide ; the second, the Staphylinde and Clavicornes; the third,
the Lamellicornes; the fourth, the Buprestide, Elateride, and Malaco-
dermata; and the fifth, with the Heteromera. The manner in which
a systematic view of the subject is given is this:—The characters of
the different groups, larger and smaller, are separately detailed; a
full exposition of the characters of each genus, with its synonymy,
is then separately given; a notice of its geographical distribution,
or any specialty relating to it, is added; and in a note, a list of all the
species hitherto described is given in the shortest space possible, with
occasional synonymical corrections. A beautiful atlas or volume of plates,
giving figures and details of the rarer genera, is to accompany the work ;
and here, as ‘in the text, every care is taken to save unnecessary expense.
In the lists of the species given in the notes, for instance, instead of bur-
dening them with the species which have been described in the chief
monographs on the subject, Professor Lacordaire assumes that these are
already in the library of every entomologist, and merely says, “ To the
150 species (or whatever the number may be) described by Dejean, add
the following.” So in the plates, nothing that is to be found in works
-easily accessible is here repeated. ‘This has been carried so far as even
to assume the aspect of a defect—at least | am sure that the majority of
purchasers would gladly have paid a little more for a larger series of
figures of rare genera than has yet been given. The result of Professor
Lacordaire’s labours, however, is that this is undoubtedly the most useful
entomological work of the present day. It is a perfect storehouse of
information, and forms a new starting-point from which entomologists
may take a fresh departure. In according to it so much commendation,
I am far from implying that it is perfect, or implicitly to be trusted to.
It is ew necessitate in great part a compilation, and, as in all compila-
tions, the accuracy of the work depends upon the accuracy of the original
deseriber, not of the compiler.
Next in importance to this work of Professor Lacordaire we have a
number of very valuable monographs. The concurrent opinion of ento-
mologists has been of late years expressed so strongly against the prac-
tice, once common, of giving isolated specific descriptions of individual
insects in transactions or periodicals, that such descriptions are now be-
coming proscribed, unless where some special reason exists for signalizing
an individual—as, for instance, its being of a very anomalous character,
so that its true position may be matter of doubt, or its supplying a vacant
gap, or furnishing an interesting unknown representative in one country
of a group peculiar to another country. Except under such circum-
stances, one does not now often meet those isolated descriptions with which
the young beginner used to essay his flight. Something connected is
now looked for, and entomological writings either assume the form of
monographs or local faunas. I shall first glance at the recent monographs.
One very important one is a monograph of the Hlateride by M. Candeze
of Liege (a pupil of M. Lacordaire), which has been executed with a care
and skill worthy of his great master. M.1l’Abbé de Marseuil’s mono-
graph of the Histerida@, lately published in the Annales of the Entomo-
122 Proceedings of the hoyal Physical Society.
logical Society of France, is another most admirable specimen of what a
monograph should be. In addition to a good description, an engraved
outline of every species is given—an assistance which those who have
puzzled over the great number of species apparently alike, and only dis-
tinguished by their delicate seulpturing and punctuation, will know how
to appreciate.
Another important monograph has been brought to a close within the
last three years—Boheman’s Monographia Cassididarum. ‘The first
volume has been before the public for some years; the second is now
also, and the favourable verdict which had been pronounced upon the first
is confirmed on the second. So many additional species have since been
discovered, that he informs me that a supplement has become necessary,
and will be published.
Two other monographs have appeared or been commenced upon other
families of the subpentamerous Phytophages. One a monograph upon the
African Cryptocephalt, published by M. Suffrian in the Linnea Entomo-
logica two years ago. M. Suffrian had previously monographed the
Cryptocephalide of Europe, and also those of North America. He is
now engaged upon those of Australia, to which, although Mr Wilson
Saunders’ papers in the 4th volume of the Transactions of the Entomo-
logical Society of London formed a valuable contribution; much still
remained to be done.
The other monograph lately published, in this group of families,
is the Catalogue of the Hispide in the British Museum, by Dr Baly—
first volume. In accordance with the enlightened course followed by
Dr Gray in publishing lists of the contents of the British Museum,
these, from originally consisting of a mere list of what was im the
museum, have gone on improving, first into a list both of deseribed spe-
cies already in the museum, and of the desiderata not in the museum ;
then advancing into a description of new species in the museum besides
those already described ; and at last assuming the form of perfect mono-
graphs by the first authorities, containing their newest views of arrange-
ment, the deseriptions of species both old and new, and this not merely
the new in the museum, but all the new that can be collected from every
quarter; so that, while practically the interest of the museum im it is
limited to the letters B. M. appended to the species it possesses, its real
interest extends to the whole scientific world. Dr Baly’s work is the pro-
duction of a careful and acute naturalist, and is a credit to the science of
this country.
Herr Gerstacker has commenced a work under the title of Entomogra-
phien, of which the first volume, lately published, contains a careful mono-
graph of the Endomychide; and as M. Guerin-Meneyille has also given his
views'on that family, firstin Mr Thomson’s Archives Entomologiques, and
afterwards in his Revue de Zoologie, we may approach the study of that dif-
ficult family without fear of suffering from imsuflicient advice. I confess,
however, that it is rather an embarras de richesses. It is possible to have too
much of a good thing; and two monographs on the same subject, published
by two eminent men at the same time, is a case in point. With the poet we
may say—‘‘ How happy could I be with either, were t’other dear charmer
away.” We have seen the same thing happen before. It happened with
Kirby and Latreille. When Kirby brought out his chiefest work, the
Monographia Apum Anghe, Latreille’s Genera appeared within a few
weeks of it; but there the competition only shed lustre upon both. Work-
ing upon a nearly new subject without communication with each other,
they hit upon the same divisions, established families and genera upon
the same characters, and, generally, the results to which they came were
s0 identical, as to give confidence to men of science that the subject had
~The President’s Address. 123
been carefully and conscientiously investigated, and that the conclusions
to which they had come were to be relied upon. One fortunate accidental
circumstance in that case prevented the embroilment of synonymy becom-
ing so great as it would otherwise have been: Kirby, instead of giving
separate generic or subgeneric names to his minor sections, indicated them
merely by a greater or less number of asterisks or Greek letters, so that
the generic names which had been given them by Latreille stood and
answered both for his own sections and for those of Kirby. In this in-
stance the same coincidence does not occur. Gerstacker has taken his
generic characters chiefly from the parts of the mouth ; Guerin-Meneville
from the elytra, the legs, and the prosternum—which latter, however, has
also been made use of by Gerstacker ; but fortunately, before Gerstacker’s
work issued from the press, he had the opportunity of seeing Guerin’s
papers, and he points out the differences between them in an appendix.
Some other valuable monographs have appeared in various periodicals,
or in occasional works which are issued by one or two zealous entomolo-
gists—in the Opuscules of Mulsant, the Archives of Thomson of Paris,
and the Etudes Entomologiques of Motschoulsky, &e., &c. In his Opus-
cules, Mulsant has published several valuable monographical papers, con-
tributions to the history of the Pedinites, and others of the Heteromera.
M. Motschoulsky has given a monograph of the Lampyride or glow-
worms, and of the Malacodermata, in his Htudes. Mr Thomson is
publishing a monograph of the Cicindelide, with coloured figures of
every species, in a style of ‘‘luwe’’ (we have no word which expresses
the meaning so well) hitherto unequalled. He has also, with equal
magnificence, in his Archives, monographed the Anacoli, Tragocephali,
&c., limited but beautiful tribes of Longicornes. Several lesser mono-
graphs have also lately appeared, such as that of M. Bouldieu on the
Ptim (Ann. Soc. Ent. Fr.); and of M. De Bonvouloir on the Thros-
cide, &e.
Let us now turn to the special additions to our knowledge of insects
and of their geographical distribution. We naturally turn our eyes first
to our native country, and inquire what advance British Entomology has
been making. From various causes, the zeal of our entomologists has
of late chiefly taken the direction of the Lepidoptera. Mr Stainton, by
his personal energy, as well as by his work on the Tineina, has given a
great impulse to the study of the Microlepidoptera; and his Entomolo-
gust’s Annual, which has been the chief outlet to the votaries of British
Entomology, has naturally been principally occupied with the department
which its editor most affects. Mr Jansen, however, in that annual has
done good service to the Coleoptera, by placing upon record the capture of
such species as were not previously known to be British—or rather, not
recorded in Stephens’ Manual as British. This record of additions, which
is prepared with much care, comes at a most suitable time to aid Mr
Waterhouse in his unpretending but most laborious construction of a
catalogue of all the British species of Coleoptera. As this is not merely
a catalogue of all Stephens’ species, with the addition of such novelties as
Mr Jansen and others may have recorded, but a careful examination of
every specimen in Stephens’ collection, and an unravelling and compari-
son with continental names of his and Kirby’s synonymes, so as to give
us a true list of what is really native (no doubtful species being admitted),
it is obvious that it is a work which could only be undertaken by a con-
summate entomologist. He has published about the half of it; and as,
for the sake of certainty and harmony with the continental nomenclature
in such difficult families as the Staphylinide and Nitidulide, he has ex-
pressly visited the continental collections, so as to see the true types of
Erichson and others, we have a work of European value. I can truly
124 Proceedings of the Royal Physical Society.
say, that there is-no work falling within my present subject which com-
prises so much skilled labour in such small space. This catalogue is the
first step towards our procuring a good manual or entomological work in
the English language, giving descriptions of the species found in Britain.
Members are aware that we have no such work, and that at present, for
good working books of reference, we must have recourse to the Continent,
although even there they are not far ahead of us, no good work on the
subject having been yet completed, although some are in progress. The
British works which we do possess are Curtis’s British Entomology,
Wilson and Duncan’s Entomologia Edinensis, and Stephens’ Illustra-
tions and Manual. Of these, Curtis’s British Entomology gives a valu-
able series of coloured plates, which are so judiciously selected as to
represent almost every one of our modern genera. The text is certainly
not equal to the plates, and I do not think that Mr Curtis would now so
consider it himself. Entomological descriptions are very different things
from what they were when he wrote that work. The arrangement also
is confused, owing to the plan adopted—bringing out the work in parts
containing a little of each department at the same time, or nearly so;
and the work generally would require to be revised to suit the modern
state of the science. The plates, however, are unsurpassed: they have
been published separately, and other use will yet be made of them. In
the meantime they give what is equivalent to the genera of most of our
British insects, and that not only in the Coleoptera, but in all the other
orders. The book, however, is cut of print, and, besides, was so expen-
sive as to put it beyond general reach. There is now an equivalent to
this book publishing in Paris, so far as the Coleoptera are concerned. It
is styled the Genera des Coleopteres d’ Europe, by M. Jacquelin du Val, a
very accurate entomologist, who first distinguished himself, some years
ago, by publishing a revision of that most perplexing family, the Bem-
bidia of EKurope. His present work gives a beautiful coloured figure,
with details, of every genus known in Kurope. The other English works
capable of assisting him in this object are the Entomologia Edinensis,
by the late Mr James Wilson and Mr W. Duncan, applicable only to a
small portion of British species, and, moreover, out of print. Stephens’
Illustrations and Manual, although of the highest value when they
first appeared, are now felt to be so cumbered with blunders and inac-
curacies, that many think it better not to use them at all. A few more
monographs of British species of certain groups, which are everything
that one could wish, so far as they go, but only embrace a small part of
the subject, will not supply the deficiency. I refer to Dawson’s British
Geodephaga, Walton’s British Curculionide, Wollaston’s Atomarie.
If I had not praised them, I would have added my own Cercyonide and
Catopside. By getting British entomologists to take up special groups
in this way, we may at last obtain materials sufficient to make it easy for
a compiler to throw the whole into one work. Until that is done, we
must look abroad ; and although we do not obtain even there anything
complete which I could recommend, we shall there find what we want in
progress, either in French or German, as our inclinations may lead us.
On the one hand, we have Fairmaire and Laboulbéne’s Faune Frangaise,
of which the first volume only is published—a large duodecimo at a cheap
price ; on the other hand we have the Insecten Deutschland, which was
commenced by Hrichson, resumed, in a spirit and with an ability worthy
of Hrichson himself, by MM. Schaum, Kraatz, and von Kiesenwetter.
M. Schaum has taken the Geodephaga and Hydradephaga in hand; M.
Kraatz has supplied the Staphylinide ; M. von Kiesenwetter is engaged
upon the Buprestide and Elateride. This is the work which I would
recommend for British entomologists. The fauna of Germany is in many

respects so similar to our own, that any new discoveries in Britain may be
reasonably expected to be species already known there ; and we thus have
not only a most careful guide to the species already known in Europe, but
the means of deciphering any novelties. There is another book of a simt-
lar nature which would be very useful to British entomologists, but is in a
manner superseded by the two preceding works—a series of volumes, by
M. Mulsant, descriptive of different sections of Coleoptera in France.
It is a good many years since he published the Lamellicornes of France,
the Palpicornes of France, the Longicornes of France, the Securipalpes
of France, and now we have the Heteromera of France in progress.
very one must admit the value of M. Mulsant’s works; but their
extreme minuteness of description renders them less popular than they
deserve.
So far as regards the Huropean fauna, a great many additions can
scarcely be expected. A number of new species from the Llandes and
the Pyrenees have been described by M. von Kiesenwetter and others ; and
some interesting small species, constituting new genera, have been dis-
covered by M. Jac. du Val, near Montpelier, and described in his Genera
des Coleopteres. Spain has done a little by the hands of Professor
Graells of Madrid, and Dr Rosenhauer of Erlangen has described some
new species from Andalusia. But the chief novelties of interest have
been drawn from two sources not thought of till of late years—namely,
ants’ nests and subterranean grottoes; the additions drawn from the
former source have been chiefly Staphylinide, and will be found in a
paper by M. Kraatz upon the Termitophila (both those in the nests of
termites and ants) published in the Linnea Entomologica last year. The
Troglodytes or subterranean families have produced several interesting
new eyeless species, and one or two genera. The most interesting points
are the fact, that every new cave, or cave-district, produces not the old
previously known cave-animals, but new species, peculiar to itself. A
curious blind new genus, Leptomastax hypogeus, has been found on
the sands of the Bay of Besika, near Constantinople, and described first
by M. Pirazzoli, and afterwards by M. Leon Fairmaire. It is peculiarly
formed, allied to the Scydmenide, and has no affinity to any of the cave-
insects we have yet seen, but has considerable resemblance to a small ant ;
and although found at large, as it were, 1 have no doubt it is an ant’s-
nest species, and will yet be found in its proper residence.
Few new additions have been made to the fauna of the north of Europe.
Prince Napoleon’s expedition appears only to have produced one new
' species, described by Reiche under the name of Patrobus Napoleonis ;
but a good deal of useful geographical material relating to that quarter
will be found in two papers by Maklin and Osten-Sacken, published in
1857 in the Stettiner Ent. Zeitung, which continues to go on prospering,
and I trust long to prosper, under the able headship of its perpetual presi-
dent Herr Dohrn (one of our foreign members), and nowise injured by
the rise of its newly established formidable rival the Berliner Entomol.
Zeitschrift, in which are to be found some very valuable papers. Among
the more important original papers which have appeared in this Journal
falls here to be mentioned a fauna of the Coleoptera of Greece, by Dr
Kraatz and M. von Kiesenwetter.
Many Russian and Siberian species have been described by Count
Motschoulsky in his Htiudes Entomologiques, and the Bulletins of the
Imperial Society of Moscow. A considerable number of species taken
during the Crimean war, in the Dobrudska, Crimea, and other shores of
the Black Sea, have been described in the Annales of the Entomological
Society of France, and elsewhere. The Baron Chaudoir continues to
enlarge our knowledge of the Caucasian and Mingrelian regions; and
MOI: EI. R
126 Proceedings of the Royal Physical Society.
M. Kolenati, in his Meletemata, has also contributed to our knowledge of
this district.
Passing round into Africa by the shores of the Mediterranean, we have
received from Messrs Reiche and Saulcy a considerable addition to our
knowledge of the entomology of Palestine, a district of which we knew
comparatively little. The materials from which this contribution has been
derived were collected during the expedition by M. de Sauley, who, the
Society may recollect, published an interesting account of his visit to the
Dead Sea a few years ago.
Continuing our course round the Mediterranean, we find in Count Mot-
schoulsky’s Htudes Entomologiques the description of a number of the
minuter Egyptian species overlooked by previous explorers. M.de Mot-
schoulsky has extended his travels into a good many districts both in the
Old and New World; and, as he is an assiduous collector as well as a
rapid describer (too rapid, most entomologists think), we have a good
many species from his pen from all parts of the world.
Continuing along the north coast of Africa, a number of new species
from Algeria have been described by M. Lucas; but this applies less to the
Coleoptera than to some of the other orders. Madeira should come in here.
Mr Wollaston has published in the form of a catalogue, consisting of a
complete series of the species of Madeiran Coleoptera in the British Mu-
seum, presented by him to that institution, a number of new species
detected since the publication of his great work on the Insecta Ma-
derensia. He returned last summer, with an immense amount of
materials for a fauna of the Canary Isles; but I grieve to say that
his state of health has been too bad to allow of his putting them into
shape.
Little new has been recorded on the west coast of Africa until we come
to Old Calabar. My descriptions of new species from that district, which
by a sort of legal fiction have been read here, have gone on appearing in
the Annals of Natural History from time to time, as suited my own con-
venience. M. Chevrolat, to whom I confided the Longicornes, published
a century of new species, among which are some of singular beauty. Dr
Baly has also described some of the new genera of Phytophages in the
Annals of Natural History.
Possibly, stimulated by the number of novelties sent home by our
friends in Old Calabar, and distributed among continental entomolo-
gists, two eminent entomologists resident in Paris, Count Mnizscheck and
Mr James Thomson, organised an expedition to the neighbouring territory
of Gaboon, and sent out M. Henry Deyrolle, son of the highly esteemed
dealer in Paris, on an expedition to that country. The results of his col-
lecting, at least those species which are new, are described in the second
volume of Mr Thomson’s Archives. From his descriptions it appears that
a considerable number of our Old Calabar species are found in Gaboon, but
that a large proportion -also is distinct; and looking to the relative num-
ber of species found, I should say that our unpractised amateurs need not
hide their heads in point of collecting with this crack collector of Paris.
To the south lies the kingdom of Angola, of whose Coleopteral fauna
little more is known than what is contained in Erichson’s fauna of that
district, published in Wiegman’s Archiv. in 18438.
The next zoological district which meets us as we journey round Africa
is the Cape, and we may include under that head the whole coast from
the Cape itself north to Natal, both inclusive. A good fauna of the Cape
was greatly wanted. Several authors, as Klug, &c., had described a
certain portion of its Coleoptera; and other authors, as Burmeister and
Schonherr, in their great works on the Lamellicornes and Curculionide,
have of course described many which fell within the scope of their subject ;
The President's Address. 127
but there was no general systematic work until Prof. Boheman, of Stock-
holm, four or five years ago, commenced his Insecta Caffraria. The first
volume was then published; and the second, containing the Lamellicornes,
has appeared during the last year. Like all Boheman’s works, this is most
satisfactory. I find a general impression among working entomologists,
that Boheman’s descriptions come nearer to what an entomological descrip-
tion should be, not only in acuteness and discrimination, but also in attain-
ing the proper medium, in point of length, than those of almost any other
living entomologist.
Madagascar stands blank. Nothing has been done to it during the
period J am reviewing, either in the way of collecting or describing, unless
we reckon as something the unsuccessful attempt of Madame Pfeiffer.
The cruelty and atrocity of the queen have made it forbidden ground, and
it is like to continue so, at all events during her life, unless some fortu-
nate political squabble with some of our ships shall rouse our Government
to interference, or a lack of other openings shall tempt some of our
missionaries to that wondrous land. ;
Signor Bertolini has supplied the collections of Europe with a fair
sample of the productions of Mozambique, and has also given descrip-
tions of the most striking.
Passing Abyssinia, the Red Sea, Arabia, Persia, and the Himalayas,
which have produced little or nothing new during the last few years, we
shall find that a good deal has been done in India, more especially in its
southern portion and Ceylon. M. Nietner has discovered and described
a good many new species from Ceylon, particularly a number of minute
species generally overlooked. Count Motschoulsky, in his last two years’
HKiudes Entomologiques, has also described a great many minute species,
some of them of very singular and abnormal appearance. A very con-
siderable number of species of Coleoptera from Ceylon have also been
described in the Annals of Natural History, during the last year, by Mr
Francis Walker, well known for his papers on the Chalcidites ; for his
two volumes on British Diptera (Insecta Britannica) ; and tor his Cata-
logues of Moths in the British Museum. Unfortunately, Mr Walker has
sacrificed everything to shortness, so that, without their apology, his
descriptions, so far as regards decipherableness, must rank with those of
Linnzus and Fabricius. Nagpore has its name, which was already dis-
tinguished in natural science, rendered still more so during the last few
years through the exertions of two Scottish missionaries, our friends Mr
Hislop and Mr Hunter. It is chiefly to geology that their studies have
been directed, and they have brought home with them a number of fossil
parts of insects, which, through their kindness, were placed in my hands
for examination and description. These, so far as they were in a condi-
tion to allow of its being done, I described in a paper which formed part
of Mr Hislop’s general geological work, now in course of publication by
the Geological Society of London. The materials were tco few and im-
perfect to generalize from ; but they all belonged to the great families still
common on the Indian continent—Buprestide, Curculionide, &e. The
structure, however, of some of them seemed to have more affinity with
certain modern Australian forms. This, however, rests on a mere hazy
resemblance, insufficient to warrant reliable deductions. The arrivals of
species from China, Hongkong, Singapore, Java, &c., have been few of
late years, and the descriptions of new species still fewer, being limited to
a few isolated species, described for their beauty, such as Carabus Fidu-
ai er abuse Celestis, &c., and afew Phytophaga, occasionally described
y Dr Baly.
M. Motschoulsky, however, has given us the descriptions of a number
of species picked up at the mouth of the Amoor and in Japan by M. Gas-
128 Proceedings of the Royal Physical Society.
kevitch, probably the same person who I see announced im the papers as
Russian Consul-general, under the name of Gorkwitch, who accompanied
the Russian admiral, Pontiatine, as naturalist, in his visit to Japan, when
the treaty with that kingdom was entered into. M. Gaskevitch was
wrecked in the Russian frigate Diana, in consequence of a terrible earth-
quake, and kindly treated by the Japanese, who subsisted the shipwrecked
crew. Thereafter, in an attempt to rejoin the Admiral in a Russian
ship, he was captured by the British, and his scientific career in these
seas closed for the time by his having been sent home to be adjudged upon
im this country ; where he no sooner arrived than he was at once ordered
to be set at liberty. He does not seem to have liked his captivity at all,
and I am sure men of science in this country will like it as little. How
any captain could have conceived it consistent with his duty to arrest a
scientific man in his career of usefuiness, under any circumstances, seems
difficult to understand; but there are always two sides to a story—and |
audi alteram partem is a rule never deviated from without subsequent
unpleasant reflections. If he has now returned to fill the important part
of Consul-general, we may expect to reap a good harvest of Coleoptera
through his friend Count Motschoulsky.
From the loss of his collections, sustained by M. Gaskevitch, the report
and descriptions of the Japan and Amoor species are very meagre, chiefly
Lepidoptera. Of the Coleoptera brought by him, M. Motschoulsky re-
marks that they offered little resemblance to our European species, and
that there were ouly found three which appear identical with those of
the west—Anomala oblonga, Anobium paniceum, and Coceinella im-
pustulata. All the rest belonged to the type of China and the Philippine
Isles.
If we have drawn little from the north of these seas of late years, the
more southern portion has amply atoned for it; Mr Wallace having sent
from Celebs, Aru, &c., a great variety of most beautiful and striking new
species. These, for the most part, yet remain to be described ; only a few
of their favourite group, the Longicornes, having been described by Mr
Pascoe in the Transactions of the Entomological Society of London ;
and by Mr Adam White, in the Proceedings of the Zoological Society of
London. I hope we shall have many more of these species deseribed by
these gentlemen.
‘There has been an intermission to the rapidity with whieh the entomo-
logy of Australia and New Aealand was becoming known. Dr Baly’s —
monograph of the genus Australica (the equivalent of our Chrysomelide)
is, | think, the last connected description of species from that quarter.
‘There is, however, a great mass of unappropriated material collected, and
it is to be hoped that ere long some labourer may arise willing to cultivate
the fields now lying vacant.
Passing on to South America, there is no work of any moment to record.
Little groups of species, and some isolated descriptions, are all that I
have to notice. One of the most interesting of these is the Agriwm
fallaciosum of Chey. (also deseriked by M. Motschoulsky, under the
name of Pinochile cenosa). it is found at the Straits of Magellan,
comes next to the Manticore of the Cape, and forms the transition
between them and the Omus of the Rocky Mountains. It thus possesses
a similar interest to the Hucrania of the deserts north of Patagonia,
which represent the Atewchi of Africa, Mr Bates, a most successful and
scientific collector, has sent home from the Amazon an immense quantity
of interesting and lovely novelties, some of which have been from time
to time described by Dr Baly, Mr Thomson, &c., but the great mass are
still undescribed. A curious genus, possessing the unique character of
being viviparous, has been described by M. Schiodte as found in Brazil ;
The President’s Address. 129
and a good many of the new species brought to this country by M. Cha-
brillac have been described by Fairmaire and others in the Transactions
of the Entomological Society of France. ‘The contributions to the en-
tomology of the Andes, in the neighbourhood of Quito, sent to this
country by our correspondent Professor Jameson, have been partially
recorded by Dr Baly and myself, and a number of small species from
Panaima have been described by Count Motschoulsky.
Dr Leconte, a worthy son of a worthy sire, has taken entire possession
of North America. He is the chief, indeed almost the only, entomological
author now working in America ; but he is a host in himself. He has
reviewed most of the difficult families in the United States; his revisions,
in fact, being singularly able monographs, evolving the most original
views. He has thus gone over the Crcindelide, Carabidae, including
the Amare and Bembidia, the Hydrocantharide, the Palpicornes, the
Buprestidae, the Hlateride, the Lamellicornes, and the Longicornes
of North America. He has, along with Dr Harris and Melsheimer,
brought out the catalogue of species of Coleoptera in the United States,
and has lent his hand in every quarter of the States to the advancement
of zoological knowledge. Iam here restricted to speaking of his doings
in relation to the Coleoptera; but, were the time fittmg, I might enlarge
on his services in regard to almost every class of animals, from the Verte-
brata downwards. In the Coleoptera, at an early period, we have from
his pen descriptions cf numerous species from California; we have de-
scriptions of species from Texas; we have descriptions of species from
Lake Superior—part of the report by Agassiz on that district ; we have
descriptions of species collected during the expedition sent to report upon
the routes proposed for the railway across the Isthmus of Panama—many
the product of his own collections, for I believe his labours asa field ento-
mologist are not less than his talents and acumen as a closet naturalist.
All this work has been done within the last few years, and it is still
going on. We may hail Dr Leconte as one of the first living entomolo-
gists; and when we remember how comparatively scant a sympathy he
has in his own country, the homage we pay him will only be the more
hearty. Thanks to the Smithsonian Institution, we shall have most of Dr
Leconte’s works in our library.
A portion of North America, possessing special interest from its resem-
blance to a part of the opposite continent of Asia—I mean the Salt Lake
region as compared with the Caspian district—has lately been somewhat
opened. M. Lorquin, an able French entomologist, has made collections
in that district, and they have reached Paris, and are in the hands of M.
Boisduval, the lepidopterist. It is the Lepidoptera to which he chiefly
restricts himself, and it is to them he specially refers in a notice of the
collection given by him to the Entomological Society of France. He
says, ‘‘ Among these insects, many, although specifically new, have the
aspect of those of the mountains of Europe, and especially of Siberia;
several even are identical with some of our species.”
Dr Asa Fitch, chiefly known as a zealous hemipterist, has lately brought
out, under the auspices of the State Government of Pennsylvania, a work
on the noxious insects of that State; among which the habits of some
Coleoptera are described. ‘The care, accuracy, and perseverance shown
in this work are very remarkable.
Such is a hasty and imperfect account of what has been doing in the
science of Entomology (department Coleoptera) for the last three years ;
for its imperfections I now crave your apology. Imperfect, however, as
it is, [ think the impression which it must leave upon our minds is one of
awe and amazement at the inexhaustible prolificness of Nature, and some-
thing also of admiration for the courage with which puny Man has set

himself to the apparently interminable task of deciphering and recording
such a towering pile of indigest materials.
The thanks of the Society were unanimously voted to Mr
Murray for his services as President, and for his interesting
and valuable address.
The following Communications were then read :—
I. Report of the Committee on Marine Zoology (with special reference to
the presence of the Whitebact (Clupea alba) in the Firth of Forth). By
Grorce Loean, Esq., W.S., Convener.
Mr George Logan read a report from the Committee on
Marine Zoology, which, after a detail of the general proceed-
ings of the committee for the past season, stated that, in
sweeping the beach near Seafield with a small Seine net, during
the months of August and September, whitebait (Clupea
alba) had been taken in considerable quantity; that speci-
mens so caught had been closely compared with the sprat or
garvey (Olupea spratius), and with the herring (Clupea
harengus), and the distinctive markings coincided in every
respect with those stated by Dr Parnell in his article on the
Ichthyology of the Firth of Forth, published in the “ Maga-
zine of Zoology and Botany” in 1837; and that, further, the
assertion of Parnell was confirmed—correcting the statement
of Yarrell to the contrary—that the tongue, and roof of the
mouth of the whitebait are furnished with teeth. Specimens
of the three species of Clupea were exhibited, and even a
cursory view showed differences in their general appearance,
although, scientifically speaking, such superficial character-
istics are not to be depended upon in the absence of specific
and abiding distinctions. The whitebait is much more silvery,
has altogether a softer and more delicate appearance than the
sprat and herring, and is much flatter or more depressed in
the body. The sprat is fuller, rounder, and much deeper in
the body, is not so silvery, and has not the same delicate
appearance. The herring is much longer and thinner than
either, has a longer head and a larger eye, and is still darker
in colour than the sprat. The reporter concluded by sub-
mitting to the Society that there needed be no further ques-

tion that the whitebait of Parnell and Yarrell existed at
present in the Firth of Forth, in many localities in great
abundance; and that, if properly fished with suitable appa-
ratus, it would probably be found very generally distributed
in the estuary. The reporter added, that when sweeping
with the net in an east wind, or any wind blowing upon the
shore, no whitebait appeared; and that, on the contrary,
during the prevalence of winds from the shore, they were
always present. A marked peculiarity was observed in re-
gard to the herring, which was absent in the whitebait and
sprat, viz. a constant effusion of blood from the mouth and
gills, and this occurred without fail in hundreds of specimens
examined.
In reference to this report, Dr M‘Bain and Mr Bryson
remarked that much credit was due to Professor Dick in
calling the attention of the public to the large supply of
whitebait to be obtained on the coast near Kinghorn and
Burntisland; and through the energy of the Professor, nets
had been obtained and premiums had been offered for the
encouragement of the Fishery.
II. A Specimen of the Canada Goose (Anser Canadensis), shot on
Duddingston Loch, was exhibited by R. F. Logan, Esq.
This bird was quite perfect, without artificial marks of any
description, and was watchful and wary, remaining always
about the middle of the lake. It was of large size.
Ill. EHwtracts of Letters from Dr Livingstone’s Expedition to the
Riwer Zambesi, Africa. By Atexanper Bryson, Esq.
Mr Alexander Bryson read extracts from letters received
from Dr Livingstone and other officers of the Zambesi expedi-
tion by a friend in Glasgow, describing the valley of the
“ Shire,” and giving some particulars of the natives, besides
stating that the steamer which had been sent from Liverpool
had turned out a complete failure in every respect; but the
information contained in these letters is in substance the
same as that which appeared in the report of the meetings of
132 Proceedings of the Royal Physical Society.
the Royal Geographical Society of London. In a note to one
of the letters Dr Livingstone says: “ A Mr Wilson of Glasgow
served us most conscientiously with provisions; everything
was of first-rate quality, and I should feel pleased if you
would thank him for me. Wilson is a good fellow, whoever
he is, and I would not go by him on any account on another
occasion.” Mr Bryson remarked, that had Franklin’s expe-
dition been supplied by such a purveyor, in all human pro-
bability they would have been spared, as it was now proved
beyond doubt that their lives were sacrificed by the accursed
cupidity of the contractors, who supplied them with putrid
provisions. Mr Bryson concluded by moving that a me-
morial to the Lords of the Treasury be prepared, urging
the Government to send a more suitable vessel to the Zam-
besi, which was unanimously agreed to.

Memorial to Government on behalf of the Livingstone Expedition.
Mr Andrew Murray reported that in accordance with the resolution of
a previous meeting, a memorial had been drawn up and forwarded to the
Chancellor of the Exchequer, praying that immediate assistance be granted
to the exploring expedition in Africa under the command of Dr Living-
stone; and he was glad to state that the assistance required had since
been granted by the Government.
The Communications read were as follows :—
I. On the Reproduction of a Medusa, belonging to the genus Lizzia. By
Professor Epwarp Criaparepe, Geneva. Communicated by Dr T.
STRETHILL WRiGHT.
M. Claparéde stated that he had captured, in September last, in Lam*
lash Bay, a number of floating eggs. On examining these eggs he foun
in each a true medusa, with four radiating gastrovascular canals, an
eight tentacles—four short and four long, the long ones corresponding to
the radiating canals. A careful search was rewarded by the discovery
of the animal which had produced these eggs, a twelve tentacled medusa
of the genus Lizzia; the bulbs, which in the embryo gave rise to the
longer tentacles, being in the adult each furnished with two of these ap-
pendages. The peduncle was laden with eggs; of these eggs some ex-
hibited a germinal vesicle and spot, others well-developed medusz, but in
none was the stage of segmentation of the yolk observed. The question
was, whether the boilies in question were eggs or buds? It was true that
no males of this form of Zizzia were found. But the males might be
more rare than the females, or, as Dr Strethill Wright had observed in
one case, might have a form different from that of the female. The
structure of the bodies was that of true eggs. The canals of the medusz
which they contained had no communication with those of the parent,
differing in this respect from the canals of the budding medusas of
Sarsia. The buds of Sarsia, moreover, did not exhibit the germinal
vesicle and spot. The author stated that the reproduction of meduse,
without the occurrence of a fixed hydroid stage, had been observed by
Gegenbaur and Krohn, but in these cases the embroyos had to undergo
important alterations in form before presenting the characters of the
parent. M. Claparéde considered it possible that reproduction in Lizzia
might also take place with the intervention of the planuloid and hydroid
stages.
Mr A. Murray congratulated the Society on its good fortune in having
commenced a correspondence with so distinguished a naturalist as M.
Claparéde; and proposed that the thanks of the Society should be trans-
mitted to him for his important communication, which was unanimously
agreed to.
Dr Strethill Wright considered M. Claparéde’s paper of the highest
importance. Its author, it was true, had not traced the gradual develop-
ment of the ovum into a medusa, nor had he seen the segmentation of the
vitellus, but Dr Wright had convinced himself that in a majority of
VOL. Il. )
134 Proceedings of the Royal Physical Society.
zoophytes the vitellus never divided; it became minutely granular and
opaque without segmentation. Still, some intermediate form might occur
even within the egg. The male of this Lizzia might differ in form or
development from the female, as was the case in the medusoids of
Atractylis (Hudendrium) ramosa, and Campanularia dichotoma
(Lovent). It was well known that although in some zoophytes the re-
productive apparatus of the male and female was identical in shape, in
others the difference was very remarkable.
II. Note on an Instantaneous Method of finding Microscopic Objects
under High Powers. By T. Stretuin, Wricut, M.D.
The author stated, that when examining small living organ-
isms under pressure, he had frequently much difficulty in
placing them under the higher-powered objectives with sufil-
cient rapidity. The animals often commenced breaking up
before they could be found. By adopting the following
method of finding objects, he could instantly, and without even
looking through the body of the microscope, place in the centre
of the field, and in focus, any object which could be barely
detected by the naked eye.
The fine adjustment slide was marked by a small scratch
on the brass-work, and it was afterwards not used. A speck
of paper or other substance, sufficiently large to be just per-
ceptible to the naked eye, was placed in water on a glass slide,
covered with thin glass, placed in the centre of the field, and
accurately focussed under the high-powered object-glass. The
coarse adjustment was then marked by a scratch on the body
of the instrument or the slide of the rack (“scratch No. 1”).
The operator then placed the point of his nose on the top of
the coarse adjustment screw-head, and the left side of his
forehead against the projecting rim of the eye-piece, and
looked towards the object with the right eye. The object
was hidden from the eye by the body of the microscope. The
body of the microscope was then raised by the coarse adjust-
ment until the object again just came into view, emerging
from behind the convex rim of the objective. This point of
adjustment was then marked (‘scratch No. 2’’). The operator
had thus four adjusted points: first, the tip of the nose;
second, the side of the forehead ; third, the most convex part
of the rim of the objective; and fourth, the object. The
three first of these adjusted points were permanent, while the

last might be changed for some other object. When the
microscope was marked as above, an object might instantly
be found and focussed at any future time by adjusting the
microscope to “scratch No. 2,” placing the nose and forehead
as described, and the object required to be focussed in the
fourth adjusted point, and screwing down the body of the
microscope to “ scratch No. 1.”
The author illustrated his method before the Society, by
instantly placing and focussing several small objects under
the microscope without looking through the eye-piece.
III. Remarks on the Musculus Kerato-Cricoideus, a Muscle of the Laryna.
(Merkel’s Muscle). By Wm. Turner, M.B. (Lond.), M.R.C.S., Senior
Demonstrator of Anatomy, University of Edinburgh.
The muscular arrangements of the human body have been,
_ during the last two or three centuries, so thoroughly examined,
and carefully described, that it rarely falls to the lot of a
modern anatomist to discover, merely by the aid of his un-
assisted vision, a new muscle. To such a structure, however,
the attention of anatomists has been recently directed by Dr
Carl Merkel of Leipsic, in an elaborate treatise on the Ana-
tomy and Physiology of the Organs of Voice and Speech
(Stimm und Sprach Organs, 1857). In this work he has de-
scribed a muscular slip occasionally extending between the
posterior surface of the cricoid cartilage and the posterior
margin of the inferior cornu of the thyroid, and thus forming
one of the intrinsic muscles of the larynx. His account of
the muscle is as follows :—
** Musculus Kerato-cricoideus. Horn-Ringknorpelmuskel.
—This small, hitherto undescribed muscle, is not found in every
larynx, and when present, it exists only on one side, for which
reason I have considered it as one of the unsymmetrical mus-
cles of the larynx. It arises, about 1-14’ broad, close to the
origin of the outer (or anterior) fibres of the musculus crico-
arytenoideus posticus, so that it appears as an additional por-
tion of the same, and probably has been hitherto so regarded by
anatomists, or as such overlooked by them. It does not, how-
ever, pass upwards with this last muscle, but extends ob-
liquely upwards and outwards, and after a short course 1s
136 Proceedings of the Royal Physical Society.
attached to the posterior margin of the inferior horn of the
thyroid cartilage. The inferior laryngeal nerve passes under
it, and the kerato-cricoid ligament crosses it at nearly a right
angle. The entire muscle is about 3-4” long. Its action,
which certainly cannot be important, is to fix the lower horn
backwards and downwards; it opposes in some measure the
part of the crico-thyroid muscle connected to the anterior
margin of the horn.” (Pp. 132, 133.)
~My attention having been directed some months ago by
Professor Goodsir to this description of Dr Merkel, I have
since that time carefully examined the larynx in almost all the
subjects received into the dissecting-rooms of the University,
and have thus been enabled to supplement the account of Dr
Merkel with some additional particulars, as well as to correct
an error into which he has fallen. ‘Thirty-two specimens have
been dissected by me, and amongst these the muscle existed
in seven cases, being in the ratio of 21°8 per cent. In four of
these it was on the right side only, in two on the left, and in
one on both sides. Thus, the statement of Merkel, that the
muscle “ exists only on one side,” is not absolutely correct ;
and although it is undoubtedly true as a general rule, yet,
like most general rules, it admits of occasional exceptions. I
have had a drawing made of the larynx, which was from a
male subject, in which this double muscle was found, an en-
graving of which is here subjoined.
The kerato-cricoid muscle is not confined to the larynx of
one sex, aS I have found it both in the male and female. The
majority of cases in which it was present were certainly in the
male, but I do not feel disposed to attach much importance
to this circumstance, as the examination of a larger number
of instances might perhaps alter the proportion, and render
it equal in the two sexes.
The muscle exhibits considerable differences in breadth;
thus I have found it as much as one-eighth of an inch broad
in one larynx (that being the broadest one I have yet seen),
and a mere thread in another,—other specimens furnishing
examples between these two extremes. In length it corre-
sponds to the distance between its origin on the cricoid and
its insertion into the inferior cornu of the thyroid,—a few

tendinous fibres being found at each of these extremities. The
muscle appears to be developed in a direct relation to the
other laryngeal muscles, for the largest example I have yet
seen occurred in a larynx the muscles of which were unusually
well formed, whilst the smallest example was found in a larynx

possessing comparatively feeble muscles; at the same time, it
must be stated that its existence in a larynx is not necessarily
coincident with a general laryngeal muscularity, as I have
dissected more than one larynx in which no trace of Merkel’s
muscle could be found, although the other muscles were ex-
tremely well developed. The inferior laryngeal nerve passes
under, z.e., in front of, this muscle, and sends a small filament
to it. The kerato-cricoideus must thus be classed amongst
the occasional muscles of the larynx, and, like other occasional

muscles, the psoas parvus for example, it is most frequently
found only on one side—either the right or left, as the case
may be—the only instance as yet recorded of its existence on
both sides being the one above figured.
With regard to its function, it must be evident that it is not
essential to the production of the voice, seeing that it is ab-
sent in the majority of persons. We cannot, however, doubt
that in those cases in which it exists, it determines certain
modifications of sound; for an organ so delicately constructed
as the human larynx, and sounds capable of such varying
modulation as those of the human voice, depending for their
production upon such minute alterations in the relative posi-
tions of the vocal cords, will necessarily be more or less
affected by the contractions of muscular fibres which, from
their attachments, are capable of changing the relative posi-
tion of these cords to each other. But until in the same indi-
vidual an examination can be made of the powers of the voice
during life, and of the muscular and other arrangements of
the larynx after death, it will be difficult to determine with
any exactness not only the function of this, but also of many
of the other laryngeal muscles.
1V. (1.) Notice of the Capture of an enormous Cycloid Fish in the Bay
of San Francisco, California. By AnpREw Murray, Esq.
This was a notice of an enormous fish taken at San Francisco. It was
360 pounds in weight, between seven and eight feet in length, and 5 feet
2 inches in girth round the body. It was supposed by its captors, who
were probably New Yorkers, to be a giant specimen of the sea basse, or
black basse, which is common on the east coast of America, especially
about New York; but a scale of the fish, which had been sent home by
Mr William Murray of San Francisco, showed that it was not a basse at
all, nor any of the perch family. The scale was cycloid, not ctenoid, and
the fish was more likely to have belonged to the sea-bream tribe of carps
than to the sea basse. No fish of that magnitude belonging to these
tribes seems hitherto to have been recorded.
(2.) Mr Anprew Murray exhibited a supposed meteoric stone, sent
from Hudson’s Bay; which, on a section being made, was found to be
simply a smooth rounded mass of ironstone.
V. The Skeleton of a Celogenys (mus) paca was exhibited by Joun
Crevanp, M.D.; and various peculiarities of its structure were pointed
out.
VI. Dr Brattosiotsxy addressed the Society at some length on the
relations of the branches of trees and plants to the parent stem, forming
as they did certain definite angles; he expressed astonishment at finding
various evergreens exposed to the cold of our winters which in Germany

were carefully kept in glass-houses. He also made some remarks in
support of the recent German theories against the generally received
opinions of the igneous origin of granite, and in favour of its aqueous
origin.
VII. (1.) Dr John Alex. Smith exhibited a Specimen of Bloch’s Top-
knot (2) (Pleuronectes punctatus, Bloch), taken near North Berwick ;
and of the 4iquoreal Pipe-fish (Nerophis equoreus, Kaup.) from the
Coast of the Isle of May.
The specimen of this small flat fish of the genus Rhombus of Yarrell
was sent to Edinburgh by Sir Hugh Dalrymple. It was taken in the be-
ginning of August last, near North Berwick. Two species of this genus
have been described as closely resembling one another,—the Rhombus
hirtus, or Muller’s Top-knot (Yarrell); and the R. punctatus, or Bloch’s
Top-knot (Yarrell). But, unfortunately, the fins of this fish not being per-
fect made it difficult to decide to which of these so-called species it belonged.*
The upper surface, the left, and brown-coloured side of the fish was very
rough, and the under surface was white, and also rough, though in a less
degree ; with the exception of the under side of the head, which was smooth.
Muller’s Top-knot was deseribed as being perfectly smooth on the under
surface, whereas Bloch’s fish was rough ; if this was a correct distinction,
it would identify the specimen as being not Muller’s but Bloch’s Top-knot,
which, as far as he was aware, had not before been observed in our
neighbouring seas. Muller’s fish was also rare; but specimens had been
obtained at distant intervals in the Firth, especially towards its mouth.
This fish measured about eight and a half inches long, by about five
inches across, including the fins.
Dr Smith also exhibited a specimen of the A%quoreal Pipe-fish,
Syngnathus or Nerophis equoreus (Kaup), measuring twenty inches
in length. It was taken about three weeks ago among the long weed
on the coast of the Isle of May. The dorsal fin, the only fin this
species has, was about two and a half inches in length, and terminated
nearly in the middle of the length of the fish, the vent being in a
line with the beginning of the last fourth of the fin. It is of rare
occurrence in our seas. Dr Parnell says, ‘‘this fish was first recorded
as British by Sir R. Sibbald in 1655, who obtained a specimen in
the Firth of Forth. No other instance of its occurrence in that locality
has since been noticed. It is one of the rarest of our British fishes.”? Dr
Kaup says, ‘‘ This species has till now been found only on the south-west
coast of Scotland, in Ireland, the Isle of Man, at Havre, and in Norway.”
He was indebted for the fish to Mr John Anderson of the Royal Em-
porium, George Street; and he had the pleasure of presenting it to the
Museum of the University. His friend Dr M‘Bain had in his possession
an imperfect specimen taken from the stomach of a cod, which was pur-
chased in Edinburgh.
(2.) Dr John Alexander Smith exhibited Specimens of the Stoat (Mustela
erminea); the Ruff (Tringa pugnax) ; the Shoveller (Anas clypeata) ;
and the Young of the Black Scoter (Oidemia nigra).
Messrs John Dickson & Son, gunmakers, Prince’s Street, had sent
for exhibition two specimens of the stoat or ermine (Mustela erminea,

Lin.) got in this neighbourhood. One was killed as early as the 27th of
October, but the other not till the beginning of January. They were
both nearly pure white, with the point of the tail black; showing the
severity of the season.
A male and female ruff (Tringa pugnasz), shot in the neighbourhood of
Carnwath in the beginning of September, were exhibited; and a young
male shoveller (Anas clypeata), shot near Aberdour in the end of December;
the keeper who killed it had never seen the bird before. Maegillivray, in
his “‘ British Birds,” mentions that “in Scotland no authentic instance of
its occurrence, at any season, has come to my knowledge.” It has, how-
ever, been observed once or twice since his time. Dr Smith also exhibited
two large ducks, one killed in November last, on the coast of Mull, the
other near Prestonpans, some weeks ago. Their unusual appearance had
attracted attention, and gave rise to some correspondence in ‘‘ The Field,”
one of the London sporting newspapers, as to the species to which they
belonged. The birds, Dr Smith said, were undoubtedly young females of
the black scoter (O:demia nigra, Flem.), the least common of our two
scoters; and, in this immature plumage, rather puzzling birds to a young
naturalist. Their general plumage was of a dusky brown; the top of the
head, from base of bill and along back of neck, brownish black; sides of
head below eye, of throat, and neck, grayish white; the abdomen of a dull
grayish brown, the brown feathers being edged with white ; under tail
coverts dark brown, no enlargement on bill, which, as well as the feet, was
of adusky brown colour. In one of the birds the bill was of a lighter colour
at the nostrils. One of these birds was sent by Mr Sanderson, birdstuffer,
and the other by Mr Small, birdstuffer, George Street. ‘Through the
kindness of Professor Allman, he was able to exhibit another immature
specimen of this bird from the valuable collection in the Museum of the
University. The occasional appearance of Oidemia nigra in this im-
mature plumage has led, it is believed by naturalists, to the introduction,
by mistake, of the Oidemia leucocephala (Steph.) among the list of
British birds. Jenyns says, there is no good authority for considering the
O. leucocephala as British. It is a bird of eastern Europe.

Osteological Remains found in a Picts House. 141
The Communications read were as follows:—
1. Notice of various Osteological Remains found in a “ Pict’s House” in
the Island of Harris. By James M‘Bain, M.D., R.N. (The speci-
mens were exhibited.)
Dr M‘Bain said, that the fragments of bone which he exhibited were
brought from the Island of Harris, by Captain Thomas, of Her Majesty’s
surveying vessel Woodlark. They were found during last summer in one of
those interesting buildings commonly called ‘‘ Picts’ Houses,”’ which was
opened at a place named Nisibost, in the Island of Harris, for the purpose
of extending former observations made by Captain Thomas upon these
ancient structures. ‘The fragments of bone had been put into the hands
of Dr M‘Bain, in order to determine to what species of animals they
belonged. And as there is historical evidence that the antiquity of
‘* Picts’ Houses” extends at least beyond a thousand years, he thought the
remains of animals preserved in these buildings worthy of being consi-
dered zoologically, in reference to the extinction or extirpation of species.
An anatomical description of the bone fragments, fifteen in number, was
given. They belonged to the following species of animals :—The dog ;
the common seal; the red deer (part of the antlers of which had been cut
and fashioned by a sharp instrument) ; the “ Bos longifrons,”’ character-
ised by the form of the cancellous horn-core, which formed one of the
specimens ; the sheep, of small size; and the right middle metacarpal or
cannon bone of a small horse, rather larger than that in the skeleton of a
Shetland pony in the Barcleian Museum of the Royal College of Surgeons
of Kdinburgh. These fragments of bone were found on the clay floor of
a ‘‘ Pict’s House,” buried under a mass of drift sand ten feet thick ; and
in an adjacent cell, a stone querne or hand-mill for grinding corn was
discovered, made of hornblende slate, but too much decomposed for pre-
servation. Dr M‘Bain stated that ‘‘ Picts’ Houses” had been divided
into two classes—the superficial, or those which are built upon the natural
surface of the soil; and the subterranean, or those which are excavated
to a greater or less extent beneath the surface. That examples of each
class existed in the Orkney Islands, where several ‘‘ Picts’ Houses” had
been explored. ‘They had generally been found to contain the bones of
domestic animals, such as the sheep, ox, and horse, along with abundance
of shells of the edible species of mollusca. In the ruins of a ‘ Pict’s
House” near Skaill, on the mainland of Orkney, the tusk of a wild boar
was discovered, ‘its presence,” as it had been remarked, ‘‘ taking us
back to a very early period.’’ In a subterranean “ Pict’s House” opened
at Savrock, near Kirkwall, in 1848, the head and part of the horns of the
red deer were found, along with the bones of sheep, cattle, horses, and a
large bone of a whale. The red deer must soon have become extinct in
Orkney, for there is no certain historic record of its being alive in the
islands, although the contrary seemed to be indicated by the fact that a
headland and a harbour still retained the names of Deerness and Deer-
sound. Reference was then made to a collection of bone fragments in the
Antiquarian Museum of Edinburgh, presented by A. H. Rhind, Esq. of
Sibster, obtained from a “ Pict’s House’? at Kettleburn, in the county
of Caithness. This collection contains the bones of the goat, pig, rat,
and fish, besides those belonging to the same species of animals as the
fragments from Nisibost. Dr M‘Bain concluded by saying, that the
investigation of ‘‘ Picts’ Houses,’’ Pictish broughs or castles, tumuli, and
other structures supposed to be of contemporaneous age, had hitherto
been undertaken chiefly upon archeological and ethnographical consider-
ations. That the primitive construction of these buildings, especially in

respect to the form of the arch, the absence of mortar and lime for cement,
and other indications of a low state of architecture, carried us back to a
remote period of barbarism, perhaps not far in advance of the time when
the Bos primigenius, with other extinct or extirpated animals, roamed
over the wild parts of Britain. That considerable attention had been
paid to the preservation of implements, weapons, ornaments, and other
relies of human art, disinterred from these ancient dwellings; but it
did not appear that much care had been bestowed upon the animal
remains, which were at least of equal importance. That the object of
his communication was to show that these had a special zoological bear-
img, and that much information of a definite character might be obtained
if the subject were to engage a more general interest, and if every one
having an opportunity were careful in collecting and preserving the re-
mains of animals found in these primitive habitations of our Celtic an-
eestors.
II. On the Structure of Pearl. By Atexanprer Bryson, Esq. (Numerous
illustrative specimens were exhibited.)
The author commenced by stating that the first mention of pearls being
used as ornaments by mankind was found in the ancient writings of the
Chinese. So early as twenty-two and a half centuries before the Chris-
tian era, pearls are enumerated as tribute or tax. In the Rh—ya, a
dictionary compiled one thousand years before Christ, pearls are men-
tioned among the most precious products of the empire. Grill, a Swede,
long resident in China, was the first who published an account of the
Chinese method of forming artificial pearls. This interesting paper is
published in the Transactions of the Royal Swedish Academy for 1772.
He says— When the shells (the Unio plicatus) rise to the surface of the
water to sun themselves, they open their valves. The Chinese, watching
their opportunity, insert between the mantle and the shell a string of
coarse, ill-coloured pearls, placed at intervals on a cord or wire. When
these are inserted, the shells sink to the bottom of the pond, where they
are allowed to remain for one year, when they are fished up and opened;
the coarse rough pearls are now found coated with a fine covering of
nacre. In the joss shells are placed clay images of Buddha, which, when
sufficiently covered with naere, are skilfully sawn out by the Chinese, and
worn and worshipped by them as the emblem of the creative power. Lin-
nus, probably unaware of what had been done in China so many hundred
years before our era, endeavoured to produce artificial pearls by piercing
the nacreous shells from without, and inserting foreign bodies; but his
success was not so great as his patron, King Frederick Adolphus, had anti-
cipated. So sanguine was his Swedish Majesty that that diseovery would
enrich his country and decorate his court, that he conferred a pension
and a patent of nobility on the great naturalist. Had this honour been
conferred on Linneus for his ‘‘ Systema Nature,’ the monarch would
have been more honoured, and the conferred title of Von Linné perhaps
respected by posterity. Unfortunately for the monarch, his empty title
is forgotten, and Linnzus, not Von Linné, remembered with veneration
by all true lovers of nature. Mr Bryson remarked that, though the
French are now by far the most successful producers of artificial pearls,
he had failed to obtain the slightest hint of the method employed, no paper
having appeared, as far as he was aware, on the subject. The only notice of
the formation of the coques de perles of the French which he had obtained
was by Von Siebold, who has given, in his “ Zeitschrift fiir Wissenschaft-
liche Zoologie,” a description of the process. It differs very little from
that followed by the Chinese. A piece of nacre is sawn from a shell

of the required form, and placed between the mantle and the shell of a
nacre-producing mollusc; when sufficiently coated, it is filled with mastic,
and a small plate of mother-of-pearl placed at the back. In regard
to British pearls, the author stated that the first notice of the gem was
by Tacitus in his ‘‘ Life of Agricola;’’ and that the pearls were the pro-
duct of the fresh-water mussel of our rivers (Unio margaritafera), was
evident from the description, that they were “not very orient, but pale
and wan.’”’ To the theory advanced by Arnoldi in 1696, anew by Sir
Hiverard Home in 1818, and also by Kellart in 1858, that pearls, or
rather their nuclei, were due to the sterile ova of the molluses which pro-
duced them, the author gave his decided opposition, as, from all the facts
which he had observed, pearls were entirely due to a secretion from the
mantle of the animal. ‘To illustrate the strueture of pearls, Mr Bryson
exhibited a larye series of sections which he had prepared, and by which
he showed that by the microscope he could at once determine what shell
had produced them. He also explained the rationale of the irridescence
of mother-of-pearl,—a discovery due to Sir David Brewster, who proved
that it was due to the diffraction of the rays of light, caused by the out-
cropping edges of the laminz, and in some cases to the minute plication of
asingle lamina. This phenomenon was also shown by Barton’s patent
buttons, where the irridescence was produced by thousands of minute
lines, so near each other as to require a high magnifying power to resolve
them. By taking an impression with black wax under considerable
pressure, the author succeeded in obtaining the same irridescence as exhi-
bited by the button itself. This experiment Sir David Brewster had tried
with success in 1815, by taking an impression in wax from a mother-of-
pearl button, and by which he demonstrated the cause of the phenomenon.
The commercial value of pearls, the author stated, was still as high as in
the days of Cleopatra. A good Scottish pearl, with fine lustre, of the size
of a pea, fetches from L.3 to L.4. The famous wager between Antony
and Cleopatra gives us an insight into the value of pearls. The twe
pearls which that luxurious queen resolved to dissolve in vinegar, and
serve up at the costly banquet, were valued at ten million of sesterces,
about L.76,000 sterling. ‘The pearl in the possession of Mr Hope, M.P.,
the largest of modern times, is not worth a fourth of that sum. The
weight of this pear! is 3 oz. ; it is 44 inches in circumference, and 2 inches
in length. Notwithstanding the great value of the pearls, the shells
of the animals yield now a far more profitable return than the jewels.
In 1856, the total value of the pearls imported into this country was
1.56,162, whereas the imports of 2102 tons of mother-of-pearl! shells were
valued at L..76,544. Mr Bryson suggested that trials should be made to
produce artificial pearls from the Iridina, a nacreous shell, having a much
higher lustre than any hitherto found. It inhabits the Nile and Senegal
rivers.
III. Notes from the neighbourhood of Stranraer—on the Chough or Red-
legged Crow (Fregilus graculus); on the Migration of the Swift
(Cypselus apus, Flem.); and on the Effects of the severe Gale on the
9th September last. By the Rev. Tuomas B. Betz, Leswalt, Wigton-
shire. Communicated in a letter to Dr J. A. Smirtn.
The Rev. T. B. Bell, in his communication, says,—‘‘ The chough is
common all along our rocky shores, building on cliffs and in caves along
with his mischievous companion the jackdaw, and sometimes in the same
cave with the rock pigeon. He annoys the farmers by digging up the
sprouting wheat, and tearing up the roofs of their stacks. He is not by
half so wary as either the rook or jackdaw, and consequently falls a fre-

quent victim to the herd-boy’s gun. He is a pretty bird, very easily
domesticated, but void of genius. He does not care to congregate, is not
clamorous, and never goes far inland—perhaps not above a mile; but he
shifts his roosting quarters frequently from one cave or rock to another,
prebably just because the wind shifts.
‘“« On the 19th of July last, I observed a migration of several hundreds
of the common swift. I knew that these birds, breeding only once in the
season, were the first of the swallow tribe to leave our shores, but I had
no idea that they left us so early. I have not had any opportunity of
watching their habits for nearly twenty years, as they do not frequent
tais peninsula; indeed these are the first I have seen here during a resi-
dence of nearly nineteen years. Perhaps l may mention the particulars
of this flitting in as few words as possible. Ist, The weather was very
warm and still, with a few fleecy clouds overhead. The hour was be-
tween five and six in the afternoon. 2d, The direction from which they
came was N.E., as 1 thought—probably from Ayrshire. They passed
over me as I stood on the shore, at a spot about five miles north of Port-
patrick, and, holding on their way, I judged, that they would reach the
Irish coast somewhere about Portaferry. 3d, Their flight was direct, and
steady, and quiet—no wheeling nor screaming, such as they practise when
feeding or sporting round some old gray tower. They seemed to have
important business on hand, and went about it in a businesslike way.
The level of their course was not high. They swept over the cliffs, which
ure not above 150 feet high, and seemed to retain the same level, as far
as I could see them crossing the Channel. I should guess the height at
about 250 feet, or even less. 4th, The order of flight.—They travelled
in a wide column. ‘The individual birds were many yards asunder; some
were 100 yards to one side, some as many to the other side of me, and in
this fashion I observed them for fully twenty minutes ; sometimes there
were twenty in sight directly overhead, then half-a-dozen, then for a
second or two there were none, and then another scattered detachment.
In this order the stream flowed on, till at length it ceased. It is difficult
to conjecture how many there may have been in all; at the time I guessed
them at nearly a thousand. I never had an opportunity of witnessing
the migrations of any of our smaller birds, except occasionally flights of
linnets in beating up to windward before a gale; and I thought that to
escape hawks they invariably moved under cover of night. Larger birds,
such as ducks, geese, swans, I have frequently seen on the move in day-
light; while the swallows which congregate on our house-tops in September
are found some morning to have made a night-flitting, and usually a
moonlight one.
‘« There is another fact I may mention to you: On Friday, the 9th Sep-
tember, we had,’’ he continues, ‘‘ our first equinoctial gale. It lasted for
about a week. On the 10th I picked up (at the place where I had seen
the swifts in July) a stormy petrel, the Procellaria pelagica of the
Atlantic. These birds were frequently seen off our shores in former
times; but now they seem to keep outside of the Mull of Cantyre.
Whether an increase of steam navigation has driven them from the
Firth of Clyde to the open ocean, I cannot say. The same gale cast
ashore a vast number of meduse. So numerous were they that each tide
left a belt of them, at high-water mark, of ten or twelve feet wide, all
along the beach. There seemed to be only one species, of a pinkish
shade, with four dull white eyes, and varied from two to four inches in
diameter. They were not so fleshy as some specie: I have seen. Those
washed up by one tide were found to be quite dry, and left little but a
membrane when the next tide came in. ‘The most remarkable result of
the gale, was the destruction of many thousands of the short-winged
Notes on the Chough or Red-legged Crow, §c. 145
sea-fowls. From Corsewall Point to the Mull of Galloway, all round
the shores of the Bay of Luce and of Loch Ryan, razor-bills and guille-
mots were lying in heaps. I did not observe any other species. |
do not think it difficult to account for the destruction of these pretty
birds. From the middle of June till the gale came on, the waters off our
coast were literally swarming with the fry of various fish. The conse-
quence was that the sea-fowl congregated in unusual numbers, which
seemed to increase day by day. The storm came on suddenly, and was
of unwonted violence for the season of the year. The fry were of course
either driven off or compelled to retire from the surface. The long-
winged gulls and gannets were able to get away by flight; while the
short-winged razor-bills, who trust more to their paddles than their
pinions, had nothing for it but either to breast the sea, or drift on to a
lee shore. Deprived of food they could not long face the heavy sea that
came rolling in from the Atlantic, and having struggled on for several
days they were at last swept ashore—most of them dead, some so ex-
hausted that they could make no effort to get away. Though thin, they
were not so thin as to suggest starvation as the sole cause of their death ; but
want of food for several days, combined with the exhaustion induced by
struggling so long against a head sea, seems sufficiently to account for the
prodigious mortality among them. This is confirmed by the fact that no
gulls nor gannets perished. The former easily obtained shelter and food
on shore, while the latter, with their tremendous power of flight, escaped
to sheltered bays and coasts.
*¢ Several years ago we had a great mortality among the guillemots, but
the features of the case were quite different. During a heavy fog in the
month of April a large flock of these birds were seen circling over the
point of the pier at Stranraer. Next morning they were found dead
and dying, scattered all over the country, some of them miles inland. I
presume they had been trading to the south——had in the mist mistaken the
entrance of Loch Ryan for the Channel; that they were brought up by the
shore, where they expected to find open sea; in fact, that they had lost
their way, and perished in attempting to find it again.
“ T cannot say that there is anything remarkable in our fauna. We
have few rare birds. The quail is resident; it is known by the name of
‘wet-my-foot,’ words which its cry closely resembles; and the country
people fancy that it is like the peacock and raven, vociferous before rain.
The young quail early develops his pugnacity ; although there are twelve
or fifteen in a brood, they cannot live in harmony till able to fly ; by the
first of August they are broken up into parties of two or three. In sum-
mer we have the pippet, the blackcap, and the grasshopper warbler. The
wild swan visits us in severe winters. Some years ago a wounded female
remained on the lake at Lochnaw, and during several successive seasons
bred with a male of the mute swan. The progeny were genuine mules,
and did not breed. A golden eagle sometimes floats high overhead, trad-
ing between the Morne Mountains in Down and the solitudes above New
Galloway. He occasionally descends to the ground.”
The Society were much indebted, Dr Smith said, to the Rev. Mr Bell
for his communication, including, as it did, various interesting facts from
his own observation. He exhibited a specimen of the chough sent him
by Mr Bell, and also one from Cornwall, which had been presented to him
by a friend. The bird was supposed by some of our ancient writers to be
peculiar to Cornwall; and hence arose the name of the Cornish chough.
Jn Cornwall, at least in the western part of the county, it seemed now to
be rare, as Dr Smith had seen no specimens there during a visit he had
the pleasure of paying last autumn to that most interesting county.
146 Proceedings of the Royal Physical Society.
It was, however, a rare bird, although found at various places along the
rocky coasts of Britain, and appeared to be abundant in Wigtonshire.
It was found in the island of Mull, in Skye, and at St Abb’s Head,
on this side of the island. The account of the migration of the swift was
also very interesting. It seemed to have been rather an early one; at
least this bird is generally described as leaving us about the beginning or
middle of August.
IV. (1.) Notice of a New Leaf Insect. By Anprew Murray, Esq.
Mr Murray exhibited a beautiful photograph of the under side of a
butterfly, in every respect exactly like a dead leaf. He had received it
from Dr William Traill, H.E.1.C., presently stationed at Russeleondah
in the Madras Presidency. Dr Traill, in transmitting the photograph,
writes :—‘‘ I wished to have sent you a curious insect, brought to me as a
leaf insect. In Singapore and the Straits, where a variety of these
singular forms are found, they are all allied to the Orthoptera, or the
genera Mantis, Empusa, Phasma, &e. 1am a good deal accustomed to
their various forms, but on this occasion 1 was completely taken in, and
until the animal moved, I thought it a dead leaf. To my surprise, I
found it to be a butterfly! When at rest, its two anterior wings (which
are slightly falcate at the tip) were pushed forward in front of its head,
so that a central line on them exactly met a similar central line on the
posterior wings, so as to simulate the mid-rib ofa leaf. The four wings
so disposed presented the most exquisite resemblance to an autumnal leaf;
and even the veining is represented with wonderful fidelity, especially if the
animal is held two or three feet from the eye of the spectator. A remorse-
less rat one night carried off the insect, along with the pin on which it
was impaled; but I had a few days before got a photograph of it made,
which I now send you. It is, however, very far from giving a just idea
of the original. The upper side of the wings were most brilliantly
coloured, but I do not remember exactly what colours.” Of course, these
brilliant colours will only be seen when the insect is in motion; when at
rest, and more exposed to danger, the folding back of the wings conceals
them, and shows only this extraordinary resemblance to a leaf. The re-
semblance is every whit as great as that exhibited by the leaf insect
proper (Phyliiwm), only being that of a dead leaf instead of a green one.
The insect appears to be undescribed, and, from its powers of concealment,
is no doubt rarely captured. Most butterflies have lines on the anterior
and posterior wings, often both above and below, which become continuous
when placed in juxtaposition ; and there are several exotic species which
have a line similar to the mid-rib of a leaf figured upon the under side
of the wings ; but none hitherto described at all approach the present in
its close resemblance to a leaf, both in shape, veining, and shading. It is
impossible, from merely a photograph of its under side, to determine its
genus ; but from its faleate anterior and single-tailed posterior wings, it
probably belongs to the same group of the Nymphalide as Amathusia
and Zeuxidia.
(2.) Description of New Sertulariade, from the Coast of California.
By Anprew Murray, Esq. (With two Plates.)
The interest which attaches to the existence of closely allied
forms in far distant regions induces me to publish the follow-

ing isolated descriptions of five new Sertulariadzfrom the coast
of California.
With one exception, they are all most nearly allied to species
found on the British coasts, viz. to Sertularia operculata,
S. jilicula, Plumularia falcata and Plumularia cristata ;
and I may notice that along with them I received the stems
of a Hudendrium which I cannot distinguish from EL. ramo-
sum of our own coast, although, from the want of the vesicles
it is impossible to decide whether it is a distinct species or
not.
-To secure absolute accuracy in the figures, they have been
drawn by the aid of the camera lucida.
1. Sertularia tricuspidata, Murr. Pl. VI. fig. 1.
Cells inversely pear-shaped and nearly opposite, a single
one in the axilla of each pinna; mouth at end of cell, aperture
obliquely truncate, tricuspid at the outer edge; middle cusp
longest. Vesicles unknown.
The habit of this species is perfectly that of S. operculata.
Its cells, however, are broader, shorter, stouter, and less acutely
conical; they are not perfectly opposite; they do not meet
each other at the base, and are more everted; they are tri-
cuspid on the outer lip, the middle cusp being longest, and the
lateral cusps are nearer it and more reflexed than is the case
in S. operculata, when it has two lateral teeth.
It grows in tufts from 2 to 3 inches high, flexuose and ser-
rulated, with polype-cells which are fully as much everted as is
usually the case in this family, instead of being less so, as is
the habit of S. operculata.
There were no vesicles in my specimens.
Bay of San Francisco.
2. Sertularia labrata, Murr. PI. V1. fig. 2.
Cells nearly opposite, a single one in the axilla of each
pinna; mouth at end of cell; lip distinct, not toothed; aper-
ture obliquely truncate. Vesicles not known.
Like S. filiculain habit. The cells, however, are differently
shaped, more like those of the last species, but not toothed.
The lip is distinct.
148 Proceedings of the Royal Physical Society.
_ I have received only a minute portion, without vesicles.
Bay of San Francisco.
3. Sertularia corniculata, Murr. Plate VI. fig. 3.
Cells not quite opposite, sometimes nearly alternate, form-
ing an open cup resting on the stem ; lip not distinct ; exterior
margin somewhat projecting at tip; a single one in the axilla
of each pinna. Vesicles pear-shaped, with two long points
projecting like horns at the thick end; aperture between them.
This is a very elegant little species, and is easily distin-
guished by the two long horns at the top of the vesicles, which
remind one somewhat of a fool’s-cap, and by the wholly open
cells.
Bay of San Francisco.
4, Plumularia gracilis, Murr. Plate VII. fig. 1.
Stem slightly flexuose, branched; branches alternately pin-
nated ; cells ranked closely in twos and threes ; tubulous, with
a plain yim slightly peaked in front ; vesicles oblong-oval.
The characters of this Plumularia do not differ greatly from
those of P. falcata; but its habit 1s so different that it can
scarcely be mistaken for it. The branches are closer, and
more thickly set, than in P. falcata; their arched disposition
is wanting; and the whole plant has more the aspect of a Ser-
tularia than a Plumularia. The cells are proportionally
larger than in P. falcata; instead of a plain truncate rim,
it has one slightly peaked in front, or excised at the sides.
Each cell has also a sort of support, like a triangular buttress,
below it, marked or lined off from the cell itself.
Bay of San Francisco.
5. Plumularia struthionides, Murr. Plate VII. fig. 2.
Shoots simple, plumous, the pinne alternate; cells close,
each occupying the whole of one side of the joint to which it
is attached, cup-shaped, with a toothed margin, of which the
teeth are unequal, the one in front projecting much more than
the rest; vesicles gibbous, girt with toothed ribs.
This species is nearly allied to P. cristata, but is much
closer in habit, both the pinne and the cells being nearer each

other. The cells are wider-mouthed and shallower. Besides
the projecting process in front, there are about ten teeth round
the margin instead of eight, and they are unequal instead of
being equal ; the first two and the last two are long and slender,
and the whole are variable in size and development. The
vesicles are considerably larger than in P. cristata, and the
ribs are toothed.
When dry, this species, like P. cristata, becomes curved in
a falcate manner, and the pinne are frequently laid to one
side, so that it assumes a good deal of the form of an ostrich
_plume, in reference to which I have given it the above specific
“name. =

(3.) Notice of Chameleon tricornis. By Mr Murray.
Mr Murray bronght under the notice of the Society some peculiarities
of this curiously-formed species of chameleon, which had been brought from
the interior of the Old Calabar district of West Africa, by one of the natives,
to the Rey. Mr Baillie, by whom it was presented to Mr Murray. The male
is characterised by three salient horny processes on the head; the female
has not these. Many lizards have singular spiny projections on all parts
of the body. In allusion to the prongs on the head it had been named
Chameleon tricornis ; but it had also two other names, OC. Owenti and C.
Bibronii, the latter having been applied to the female.
The Rey. Mr Baillie remarked, that this species was said by the natives
to feed upon a particular kind of tree, on which it was usually found; but
that this was, no doubt, an error, arising from the chameleon frequenting
this tree in consequence of its being more peculiarly the habitat of the
insects it fed upon those around it.

part of the dorsal fin, which were now faded. This species was distin-
guished by the soft rays of the dorsal fin, measuring twice the length of
the twenty (first) spinous ones. The Society had been indebted at various
times to Captain Orde for the exhibition of specimens of interest. The
ballan wrasse was a rare fish in our Firth, and was found generally on
rocky coasts. Dr Smith had seen some large ones last autumn, caught at
the rocks beside the Lizard Light in Cornwall.
VI. Dr Jonn Atex. Smit exhibited a specimen of a female Gadwall
duck, Querquedula strepera, one of our very rare winter visitors. It was
shot near Cromarty in the end of January, and was sent to Dr Smith by
Mr Muirhead, Queen Street.
Dr Smith referred to the great abundance in this neighbourhood of the
Brambling, Fringilla montifringilla, and of the Siskin, #’. spenws, during
the severe weather of the winter; and also to the multitudes of wood .
pigeons, Columba palumbus, which, from stress of weather and starvation,
had been driven from the more open, and wooded districts to the neigh-
bourhood of our gardens and towns, and had eaten up, with the exception
of the leek, all kinds of garden produce.
The thanks of the Society were given to the Rey. Mr Bell and Captain
Orde for their communications and exhibitions of specimens.

Dr J. A. Smith stated he might also take this opportunity
of informing the Society that the movement begun some
time ago to raise money by public subscription, for purchasing
the Museum of the late Hugh Miller, had been brought to a
successful termination. A committee was appointed, of which
he had the honour to be a member; and the result of its
labours was that above L.600 had been collected. With this
sum, and the addition of the Government grant of L.500, the
Museum had been purchased, and was now in the custody
of Professor Allman, in the rooms of the University.

I. On the Employment of Transparent Injections in the Examination
of the Minute Structure of the Hwman Pancreas. By Wm. Turner,
_M_B. (Lond.), Senior Demonstrator of Anatomy, University of Edin-
burgh. |
The mvestigation of the relations of the minute gland ducts
to the ultimate gland follicles in the human pancreas presents
considerable difficulties. This is owing, partly, to the great
delicacy and transparency of the structures, and partly, be-
cause from the close manner in which the minute lobules of
the gland are crowded together, it is difficult to obtain a
satisfactory view of a single isolated lobule. Thus, the mode
of connection of the fine excretory duct of the lobule with the
sacculated gland follicles at its extremity cannot clearly be
estimated. Moreover, if it is attempted to separate the lobules
from each other by tearing them asunder with needles, the
relations of the parts become so disturbed, that the examina-
tion does not afford any very decided results. For these
reasons, it has been customary, in describing the minute
structure of this gland, to refer especially to the appearance
which it presents in the smaller and more common Rodents,
such as the Rat or Mouse.
In these animals the pancreas is spread out in a thin arbo-
152 Proceedings of the Royal Physical Society.
rescent manner between two layers of peritoneum, so that the
different lobules lie mostly on the same plane. Their investi-
gation is on this account comparatively easy, even without the
aid of any dissection.”
Being engaged some months ago in making a series of pre-
parations of the human pancreas for the sake of illustrating
the structure of this gland to my microscopic class, I suc-
ceeded in forcing an injection through the excretory duct into
the ultimate follicles of the gland. I have been enabled in
this manner to obtain, much more satisfactorily than by any
other process, definite views of their relations to each other.
The injecting fluid which I used was of the same composition
as that recommended by Dr Lionel Beale, and employed by
him with such success in his investigations into the minute
structure of the liver. It is composed of a mixture of glyce-
rine, spirits of wine, and water, in which Prussian blue, ob-
tained by precipitation, is suspended.
This injection possesses the great advantage of flowing
easily when cold along the ducts, and from its great trans-
parency, the organ into which it is thrown can be examined
by transmitted light, and by high magnifying powers, so that
the connections and relations of its component structures can
be much more readily traced than in those cases where opaque
injections are employed. It is hardly possible, however, to
make a complete injection of all the ultimate lobules through-
out the pancreas; for in many parts they appear to be so filled
with secreting cells, and the fine ducts proceeding from them
are, in a similar manner, so blocked up with closely packed
epithelium, that the injection cannot flow along them. But
this does not throw any obstruction in the way of an exami-
nation of those lobules into which the injection has passed;
it rather tends to facilitate it, for the outline of the ultimate
follicles, distended by the blue fluid, comes out more distinetly,
by the contrast which it presents to the paler non-injected
portions,
It will be frequently found advantageous to examine those
lobules, the sacculated follicles of which are only partially

filled by the injection; for in them the general and relative
arrangement can be more distinctly seen than in those lobules
which are completely distended, as in the latter case, owing
to the amount of injection in them, a degree of opacity is pro-
duced which renders the outline of many of the follicles some-
what indistinct. Most of the sections which I have examined
have been made with a Valentin’s knife, and the preparations
have been soaked for a short time in glycerine, which facili-
tates the investigation of the pancreas, as of many other animal
textures, by increasing the transparency.
The large excretory duct of the pancreas extends along the
centre of the gland from head to tail, and is enclosed on all
sides by the large lobules. From it, at frequent intervals,
smaller ducts proceed, which pass into these large lobules,
and in them divide and subdivide into fine branches, for the
ultimate lobules. Of these fine branches some arise at right
angles, others at a more or less acute angle, and after a very
short course they become connected with the ultimate gland
follicles of the lobule to which they belong. Hach duct, as a
general rule, preserves the same calibre from the point at
which it commences, to that at which it either gives off a
branch, or terminates in an ultimate lobule. In some instances
the ducts possess dilatations on their walls, which may either
be confined to one side, or may exist at corresponding points
on both sides. The same mode. of termination of the fine
ducts in the ultimate lobules does not appear to exist in all
cases, but admits of slight differences. In some instances the
duct passes to the base of the lobule, and then from it, as
from a centre, the saccular dilatations of the ultimate follicles
spring. In others the duct runs for a short distance along
the base of the lobule, giving origin in its course to the fol-
licles, which are connected to its sides and extremity. In
either case the fine membrane forming the wall of the duct is
continuous with the membrane constituting the wall of the
follicles, so that the cavities of the follicles are continuous
with that of the duct. The number of follicles present in an
ultimate lobule varies considerably in different specimens.
There are also great differences in their shape and size.
Some are spheroidal, others laterally elongated, so as to pre-

sent a more or less oval form; others again are more pyriform
When distended by injection, they all present convex, smooth,
and well-defined outlines. On account of the general shape
of the follicles, and the mode in which they are grouped to-
gether in the lobule, they resemble in appearance a bunch of
grapes, with which they have frequently been compared.
The epithelial contents of the follicles are of course com-
pletely concealed in the injected portions of the gland; but in
those lobules into which the injection has not passed, the
shape and general arrangement of the secreting epithelium
may be conveniently studied. It frequently happens that, in
examining sections of the gland, isolated follicles may be seen,
lying perhaps closely together, as if they had originally formed
parts of the some lobule, but still separated by slight intervals
from each other, having probably become detached from their
original connections in the act of making the section. In
these isolated follicles the secreting cells may be generally
very distinctly seen. They form a closely packed layer, lining
the inner surface of the membrane forming the wall of the
follicle. Their shape is spheroidal, so that they form a true
glandular epithelium.
Professor Kolliker in his ‘‘ Microscopic Anatomy,” describes
the pancreas as belonging to the compound racemose group of
glands, of which the salivary glands and the mucous glands of
the mouth may be taken as the type. In his description of
the last-named glands, he states that the grape-like appearance
of the ultimate follicles is owing to the fine ducts being coiled
upon themselves, presenting at intervals numerous simple or
compound dilatations or diverticula. He considers the glan-
dular vesicles to be nothing more than these dilatations. In
my examination of the injected pancreas, | have not succeeded
in sufficiently separating from each other the various follicles
making up a lobule, so as to state whether the view of Profes-
sor Kélliker can be applied to the pancreas. Whether we
hold, however, with the more generally accepted doctrine, that
these follicles are saccular dilatations at the extremity of the
duct, or with Professor Kolliker that they are produced by a
coiling of the duct upon itself, the important fact still remains,
that the membrane forming the wall of the follicles is connected

with that forming the wall of the duct, and that the cavity of
the one is continuous with that of the other.
In this communication I have avoided the use of the term
acini, as it has been employed by different observers to express
different structures, so that its use is liable to lead to confusion
of ideas; some applying the term to express the ultimate
lobules of the gland, whilst by others it is used to signify the
ultimate follicles of these lobules.
II. Notice of Reptilan Fossils, Morayshire. By Wittiam Reto, Esq.
The specimens which Mr Rhind exhibited of reptilian remains from the
sandstone of Moray were contributed by Patrick Duff, Esq. It is now
about a quarter of a century since the late lamented President of this
Society, Professor Fleming, first detected an organism in the Old Red
Sandstone of Scotland. It was but a minute fragment of a fish scale, yet
it had the effect of awakening an interest for, and stimulating a research
into, those beds of sandstone which skirt almost the whole of the Scottish
shores to the north of the Firth of Forth, and which hitherto had been
looked upon as destitute of organic remains. A few years after this dis-
covery, Mr Duff began his researches in Morayshire, with an enthusiasm
and perseverance which have seldom been equalled. He soon found
that the sandstones of Moray teemed with organic remains, as well as
these of the opposite shores of Cromarty, which were at the same period
under the scrutiny of Mr Hugh Miller. From that time Mr Duff
has formed the nucleus round which the researches of other scientific
men and the casual discoveries of the workmen in the various quarries
have centred, so that a most varied and interesting assortment of specimens
have been accumulated. As long as the organisms brought to light par-
took of the character, or were supposed to do so, of fishes, no doubts re-
mained that the sandstones of Moray, under the several modifications of
colour and position, belonged to the Devonian era; but subsequently, when
organisms of a higher order made their appearance, assuming the distinct
forms of reptiles of various families and sizes, a doubt began to arise
whether the fish-bearing and the reptile-producing strata belonged to the
same series. This gwestio vewata still prevails; and Mr Rhind, assuming
that the decision is still left open, proceeded to exhibit by a section the
relative positions of the sandstone beds, in so far as these are open to
inspection. The general conformity of the lowest red, the greyish, and
the yellow sandstones,—the parallelism of the dip of these three beds
of strata, and the superposition of a band of limestone or cornstone com-
mencing south of Elgin, and seen with more or less interruption at Links-
field, Spynie, and Stotfield, capping and inclosing the whole series, were
ee out; while the absence of scales of the distinctive fishes of the
evonian era in the particular localities where the reptilian remains have
been discovered was also mentioned,— an absence which probably may
arise from as yet defective search, considering that the accidental disinter-
ment of the reptiles has’ occurred within the short space of a few years,
and that another few years may either add the discovery of fish scales,
or, if not found, afford a somewhat negative proof of the non-identity of
the yellow sandstones with the Devonian. It was also suggested that the
appearance of the vast masses of compact sandstone forming the hills

which traverse the lower region of Moray from west to east, indicated a
process of accumulation by drifting, rather than that slow and regular
deposition which is indicated in the lower red sandstone beds, where con-
glomerate, shale, and fine-grained sandstones are alternately super-
imposed,—a condition always favourable to the existence of organic
remains either of plants or animals; while the drifting process, which
carried the land reptiles into the sea, was unfavourable to the preservation
of fishes, Lastly, allusion was made to the recent discoveries of vege-
table remains of Lepidodendrons, Lycopodiums, and others analogous to
those of the coal strata in the true Devonian sandstones of Canada, by Mr
Dawson, and of similar fossil plants found in the Caithness slates, by Mr
Salter,—all indicative of dry land, and the progress of organic life during
the period of the Devonian Sea.
III. Contributions to the Fauna of Old Calabar—Mammale. By
Anprew Murray.
This paper was chiefly occupied with a list and notes relat-
ing to the various animals, of which specimens had been sent
at different times by the United Presbyterian missionaries
stationed at Old Calabar, among which were the following :-—
Troglodytes niger—The Chimpanzee.
With reference to a specimen of this animal which had been
brought away alive by the Rev. Mr Baillie, but which unfortu-
nately died on the passage home, Mr Murray remarked, that
it had been preserved by Professor Goodsir, in a way which, if
it should prove successful, was well worthy of adoption, in cases
where the rarity or value of the specimens might justify the
expense. The plan was to place it in spirits in a glass tank
or coffin as it were, covered with glass hermetically sealed
down. This is an enlargement of the plan devised by Goadby
for the display of his minute dissections; but as in his little
glass boxes, so here, the difficulty to be contended against was
leakage. Do what one can leakage seems almost always
to occur after a certain lapse of time; but this could be con-
quered if by no other means, at all events by soldering the
glass together by the blow-pipe ; so that where it is desirable
to have recourse to this plan, this difficulty in the manipula-
tion need prove no insurmountable obstacle.
Mr Murray detailed some anecdotes relating to the indi-
vidual in question, which had been communicated to him by
Mr Baillie, illustrative of the kind and extent of intellect
possessed by it. For example—It was very fond of some sweet-

meats, which were kept in a press or cupboard, but to prevent
its getting access to them when not wished, the cupboard was
kept locked. On one occasion the key had been forgotten
and left lying on the table, the chimpanzee noticed this,
secured the key, and when no one was present, proceeded to
unlock the door of the cupboard, but being unable to reach the
key-hole, drew a chair to the side of it, and getting up on it
unlocked the door, and so got access to the desired sweetmeats,
an act involving more than one process of that kind of ratiocina-
tion which is usually thought the exclusive property of man.
Galago Murinus.—(Murr.)
In addition to the information formerly given regarding
this interesting little animal, Mr Murray had received some
additional facts, communicated to him by the Rev. W. C.
Thomson, through Dr Hewan. From these it appeared that
the little creatures are gregarious, or social rather, travelling
in small companies, and inhabiting a common nest; one of
which Mr Thomson got a glimpse of. He saw several indivi-
duals rush out of it as he passed, and it answered in its situa-
tion and description to the account he had received of them,
which was, that they were built on suitable forks on trees,
with a foundation of clay, and superstructure of dried leaves.
Stenops, Potto (%).
Two or three specimens of this curious loris have been re-
ceived, and the singular structure under the tongue (a develop-
ment no doubt of the frenum, but exceedingly like a bird’s
tongue), as well as the rete mirabile of the arteries of the
limbs, was well shown in Mr Murray’s preparations.
The sublingual plate is also found in the Galago, although
less developed.
Mephitis—Sub Genus Rhabdogale (sp. ¢)
Mr Oliphant has received a specimen of an animal which
Dr Cleland, to whom he has presented it, refers to this genus,
but he has not yet satisfied himself as to the species.
Anahyster—(Nov. Genus of Otters.)—Calabaricus Murr.
If a difference in the dentition be, as is usually allowed,
VOU. IL x
158 Proceedings of the Royal Physical Society.
sufficient to warrant the separation of the animal possessing
it into distinct genus, then the present species is entitled to
that place. ,
It is as yet only known by the skull, which was sent by
Mr Thomson to Mr Murray. Its dentition differs from that
of our common otter, Lutra vulgaris, in having one fewer pre-
molar in the upper jaw. Mr Murray had submitted it to
Professor Owen, who believes it to be nondescript, and that it
approaches Enhydra of Fleming (Phil. of Zool.) in having the
first pre-molar suppressed above, but that the latter has also
the first pre-molar suppressed below. It has, however, six in-
cisors in the under jaw, while the sea otter, Enhydra, has only
four in the adult state, which the specimen in question has.
It would appear to form an intermediate link between the
true otter and the sea otter; and its habitat in an estuary
may therefore perhaps be thought suitable enough; and it was
in reference to this that Mr Murray proposed the above generic
name for it—Anahyster (belonging to an estuary).
Phacocherus, (sp. ¢)
Dr Cleland has received a young individual of this genus ;
there does not appear to be any essential difference between
it and the Cape of Good Hope and Mozambique species, PA.
MAthiopicus. But the individual is too young to allow an
opinion to be given with confidence.
Hippopotamus amphibius.—Lin.
From the information received from the missionaries, there
is good reason to believe that the hippopotamus is found in
the Old Calabar River further up than the mission stations ;
but no specimens, or portions of specimens, have yet been
sent home. It may be a question whether there are more
than one species of hippopotamus. It is generally supposed
there is only one, but it has been found in rivers so widely,
and apparently impassably, separated, that it would be noways
surprising if more than one species shall yet be determined.
Manatus Senegalensis.—Desmar.
Several skulls of this most interesting animal have now
found their way into this country from our Old Calabar friends.
Contributions to the Natural History of Old Calabar. 159
Delphinus (sp. ?)
Mr Oliphant has received the head of a species of dolphin.
Rhinomus soricoides.—(Nov. Gen., Nov. Sp. ?)—Murr.
This is a very puzzling little animal. It has the appear-
ance of a shrew, with its long snout, but is in reality a mouse.
Its dentition is somewhat peculiar, the incisors having a pro-
cess behind them, like the cusp of a carnivorous tooth. It is
pentadactylous both before and behind, and as all the allied
genera and species have four fingers before and five behind,
Mr Murray considered that there was no alternative but to
make a new genus for its reception, and in reference to its
long snout, he proposed the above name for it.
It is mouse-coloured, with ear and tail.
IV. On the Chalk Flints of the Island of Stroma, and Vicinity of
John o’ Groat’s, in the County of Caithness. By Cuartes W. Pracu,
Esq., Wick.
Notices of the occurrence of chalk flints in the boulder clay
of Caithness have from time to time appeared in various pub-
lications. Many of the localities I have been able to verify,
and to add new ones as well. Knowing the interest attaching
to their presence so far north, and not being able to find any
account in any work that I have access to of their having
been found on the surface of the land, the intent of this
communication is to show that I have been fortunate enough
to make that discovery.
On the Sth instant I had to go to the island of Stroma on
business. When walking across the north side of it, I was
somewhat surprised to find chalk flints in considerable abun-
dance on the surface there. This part of the island is stripped
of its turfy covering, and is consequently favourable for obser-
vation. Wherever I went, even on ploughed land, and where
the short vegetation was not too thick, I met with the fiints.
They vary in size from that of a boy’s marble to eight or ten
inches over, and are generally of a light colour. Some con-
tain sponges; in most of them spicula may be seen in thin
splinters, which I chipped off, and in one piece I observed
those hollow and branched spicula with the small hall-like
160 Proceedings of the Royal Physical Society.
masses peculiar to the genus Geodia—all beautiful objects for
the microscope. A large one, of several pounds weight, con-
tained pieces of shells, a fragment of an echinus, as well as
sponge. The flints are slightly waterworn, and many of them
vovered with lichens. With them are blocks of granite and
gneiss, some of large size, smaller pieces of hornblende,
reddish conglomerate, quartz, &c., &c.; in short, the usual
heterogeneous collection of travelled stones found in these
parts. One kind of rock deserves special notice. It is that
peculiar quartz rock with the large annelide-tubes, so abun-
dant in the highlands of Assynt, Durness, &c., in Sutherland-
shire. There is no mistaking it, its character is so obvious.
For its history see Sir Roderick Murchison’s last edition of
“ Siluria.” I would here remark that the north end and west
side of the small island of Stroma have never been under cul-
tivation, being too much exposed to the blighting winds and
burning spray which, when the storm is raging, pass over
these parts; and, although some of the cliffs are more than
100 feet in height, the sea-water at times rushes in streams
thence to the opposite side of the island.
I was told by James Simpson, an intelligent fisherman,
that he had often heard his grandmother say, that in her time
the supply of peat for fuel for the islanders was cut there, and
that the moss was then three feet in depth. All has been
long since taken away, and the scanty vegetation and mould
which subsequently formed has also been pared off by the
flaughtering spade, for divots either for the covering of houses,
&c., or “backing” for fires, and thus the collection of stones
on this now truly sterile spot is well exposed, and washed
and bleached by the storms of winter, and the more genial
showers and sun of summer. These stranger stones, although
now mingled with others “native and to the manner born,”
show marks which tell of scratching and polishing, move-
ment and rough usage, after having been torn from their
native mountains and hills; and it is interesting to mquire
into their age, mode of transportation, and deposition there.
Deposited with the peat they could not be, they date beyond
that time. The boulder clay period suggests itself, and I
think correctly; for although but very slight traces of the
Chalk Flints of the Island of Stroma. | 161
clay itself are to be seen on the island now, there are evidences
of its former presence. But probably it was never of great
depth, there being no deep valleys or sheltered coves to retain
it on this small spot of land. Add to this the peculiar form
of the island, sloping towards the sea on both sides and ends,
much like the hipped low roof of a house—in some places de-
scending quite to the level of the beach. Thus, when rising
on its return voyage, after being submerged and covered with
the boulder clay, as it slowly lifted up its head from the agi-
tated waters of the turbulent Pentland, lashed no doubt then
as now by the waves of the restless ‘‘ Swelkie”* and ‘“‘ Bores’ t
the softer and lighter portions of the clay were washed out,
and passed down the sloping sides in muddy streams, and
were swept away by the furious tides which ran past, the more
ponderous and weighty materials being left behind. Whence
the flints came I do not intend to speculate, but merely men-
tion that many writers upon those found in other parts of
Scotland point to Denmark and Sweden. My stay on the
island on this occasion was very short, but this is of little
consequence, as my son William has since made a thorough
inspection of the whole island, and finds flints all over.
The next morning I passed over the Pentland in the midst
of a storm, with rain and snow, and whilst my horse was feed-
ing and being got ready for my return home, I took the oppor-
tunity of looking round John o’ Groat’s, and there chalk flints
were to be seen, but not in that abundance as at Stroma. I
regretted that I could not extend my search further. As the
subject is worthy of attention, I hope to pursue my investi-
gations as opportunities offer, for I believe that these flints are
wide spread, not only zm the boulder clays of Caithness, but
on the surface also. I hope by thus giving publicity to the
discovery that the attention of others may be called to the
subject.
* “ Swelkie ” is a whirlpool off the north end of the island, which at times
is very dangerous. A boat, with seven men in it, was drawn in, and all were
sucked down and lost,
+ “Bores.” For instance, off Duncansbay Head the waters rise up all on
sudden at certain times of the tide into high waves. It is then dangerous for
vessels and boats to pass through—almost certain destruction to boats.

V. Note of the Onuphis tubicola found near Wick. By Coarues W.
Pracu, Esq.
I am not aware whether the Onuphis tubicola has been
noticed as occurring in Scotland. It has been found in Ire-
land, and I got it rather plentiful in Cornwall. It forms a
quill-like tube, which it fixes in the sand. I got one the be-
ginning of this month from a fishing-boat belonging to this
place. The animal was not in the tube, and although the
tube is injured, there is sufficient left to identify it. The
animal is described and figured in the ‘‘ Annals and Magazine
of Natural History” (vol. xvi. page 6, 1845), in a paper by
Dr George Johnston of Berwick, fifteen yearsago. I supplied
him with specimens, and when [ lived in Cornwall, I kept
some alive for more than a year.*

Obscure Markings upon an Old Red Sandstone. 163
The communications read were as follows :—
I. On some Obscure Markings upon an Old Red Sandstone Slab at
Mill of Ash, near Dunblane. By the Rev. Ropert Honter, late of
Nagpore.
The large slab, half of which has been laid upon the table,
is a micaceous flagstone, from a fissile layer, a few inches thick,
with a more compact sandstone or gritstone both above and
below it, and at no great distance from a trappean effusion.
It would seem to belong to the lowest or Cephalaspis zone
of the Old Red Sandstone. The Rev. Walter Smith, of Free
Roxburgh Church, in this city, when with me last August, in
a quarry at Mill of Ash, observed some of the markings on a
projecting ledge of stone, and that day and the next he and I
laid the rock bare for a space of six feet in length by five in
breadth, and came on about 150 of the markings. More
recently, the slab was raised, and the Rev. Mr Paterson, of
Dunblane, kindly consented to take the trouble of having it
packed and forwarded to Edinburgh. The impressions are of
two sizes. Their form is elliptical, with a raised border, one
side being in much bolder relief than the other; and it is im-
portant to note that the raised margins all correspond in posi-
tion with each other. Within, and separated from the elevated
border by a channel, there 1s occasionally a raised central
space, with a tendency to longitudinal furrowing. The longer
axes of the ellipses all point nearly in the same direction.
They are arranged with some regularity, though at times two
are in such close contact as to form an eight figure, and, more
rarely, a couple of these eights uniting have constituted a rude
cross. Mr Page possesses some curious impressions from
Ardoch, a few miles north of Mill of Ash, but judging from
some figures he hastily drew for comparison, they are of forms
entirely different from those now described. It is difficult to
say whether the markings are of organic or inorganic origin.
The hypothesis on the subject which most naturally arises,
and being expelled has a tendency to return, is, that they are
footprints of some animal. There are, however, very formidable
objections to this view. Nor can they well have been formed
by pebbles, or by the impressions of ganoid scales, for sub-
164 Proceedings of the Royal Physical Society.
stances generally so indestructible would surely have left some
fragment of themselves, more or less, which they have not done.
Most of the markings are formed chiefly of micaceous lamina,
like the rest of the rock, and in the two or three instances
where the presence of a foreign body can be detected, it seems
to be of a concretionary nature. Mr Robert Loudon Irvine,
of Hurlet Chemical Works, who kindly consented to analyse
one of these foreign bodies sufficiently to determine its chief
ingredients, thus reports on it. “ It consists mainly of car-
bonate of lime, with iron existing mostly in the state of pro-
toxide and alumina. There are neither sulphates nor sul-
phurets present. The black colour is probably due to the
presence of carbonate of protoxide of iron.” Sir Roderick
Murchison and the Rev. Mr Mitchell of Craig have, indepen-
dently of each other, pointed out a remote resemblance in the
impressions to what is in Forfarshire called “the Kelpie’s
foot;” but neither of those gentlemen regards the pheno-
mena as identical. At the suggestion of Sir Roderick, the
matter has been referred to Professor Phillips of Oxford, who
has had much experience of obscure markings like the present.
He has already received specimens of the impressions; and
it is probable that one of the larger pieces of the slab will
have to go to England for thorough examination there.
IL. Notice of Various Ornithic Fossil Bones from New Zealand.
By James M‘Bain, M.D., R.N.
The bones which I have now the pleasure of exhibiting to
the Royal Physical Society were found ina limestone cave in
the northern island of New Zealand, and were given to me for
examination by Mr D. F. Paterson, of Kerr Street, near Stock-
bridge, in this city. In a letter received from Mr Paterson,
he states, that ‘‘ the large bones were sent home by Dr A..S:
Thomson, of the 58th regiment, to his father, James Thom-
son, Esq. of Glendowan, asrare bones. Theskull was unknown
to Dr Thomson, and differed from all the Moa’s skulls that he
had seen ; at the same time, he thinks it belongs to the genus
Dinornis. The bones of the little bird, found along with the
others, were altogether unknown. |The cave in which the bones
were found is on the western side of the North Island, near
Ornithic Fossil Bones from New Zealand. 165
‘Rotomarrama, at the bottom of a hill. The entrance is twenty-
five feet high and eighteen feet broad, and its mouth is con-
cealed with shrubs. The cave is about a mile in length, run-
ning under the hill, and the bones are found in all parts; some
under soft sand and limestone, others covered with a crust of
limestone only. Glowworms were seen in the cave, but ne
plants. This is called the Cave of the Spirit. Itis held in
great terror by the natives, and some now alive say they have
seen a living moa, that it lived in the cave, and used to stand
on one foot, so that it is just possible that the moa may still
be alive in some of the wildest and most secluded parts of the
island. Dr Thomson gave some bones to Governor Gray
several years ago, and is not quite sure that the governor did
not give them to Professor Owen. ‘There is another limestone
cave, called the Cave of the Moa: this is of less extent than
the former, and is about seventeen miles from Honipaka.
The animals resorted to the caves to die. The natives used the
larger bones to make fish-hooks, the skulls to hold their tatoo-
ing powder, and for other purposes; thus, few of the leg-bones
or skulls can now be got.”
In November 1839, Professor Owen read a communication
before the Zoological Society of London, in which he described
a portion of the shaft of a femur, six inches in length, and five
and a half inches in circumference, which had been brought
from New Zealand. After a careful and critical examination,
that distinguished paleontologist pronounced the fragment of
bone to belong to a large bird, allied to the ostrich; and
staked his anatomical reputation, that species of birds heavier
and more sluggish than the ostrich would be discovered to
have existed in New Zealand. In less than four years after-
wards, this inference was happily confirmed from numerous
bones transmitted to this country, which were found in the
bed and banks of fresh water rivers at Poverty Bay, buried
only at a little depth in the mud. From these fragments of
bone, Professor Owen was enabled to establish three genera of
extinet birds, which he named Dinornis, Palapteryx, and Ap-
tornis. :
In 1847, the late Dr Gideon Mantell received from his son.

fossil bones, which were obtained from North Island, found
in a bed of sand called the “ Waingongora Bone-bed.” In
1850, another collection of about five hundred specimens of
fossil bones were sent home by Mr Walter Mantell, two
hundred of which were from the same locality as the former,
whilst the remainder were obtained from Waikouaiti, on the
eastern coast of the Middle Island. This latter bone-bed is
‘covered by a layer of sand, and appears to have been an ancient
swamp or moss, in which the New Zealand flax (Phormium
tenax) once flourished. A pair of perfect tarso-metatarsal
bones were found standing erect in this bed, with all the toe-
bones attached, which are now known to form part of the
skeleton of the species that has received the name of “ Dinor-
nis robustus.”
From the fragments of ornithic fossil bones transmitted at
various times from New Zealand, Professor Owen has suc-
ceeded in establishing thirteen species of extinct birds, differ-
ing in size from the great Bustard to that of the Ostrich, and
even much larger. These species have been referred to two
distinct genera, the Dinornis proper, in which there is no im-
pression for a hind toe on the tarso-metatarsal bones ; and to
the genus Palapteryx, in which the impression for the fourth
toe has a similar position in the tarso-metatarsal bones as in
the existing Apteryx. The general anatomical characters as-
signed by Professor Owen to the skull in this peculiar family
of birds are “‘a broad and low supraoccipital region, sloping
from below upwards; a flat parietal surface continued directly
forwards into a broad downward sloping frontal region ; wide
and deep temporal fosse, small orbital cavities, and large
olfactory chambers; the vertical plane of the foramen mag-
num, with the single occipital condyle projecting directly
backwards. No ‘existing bird,’ he says, ‘presents this
peculiarity, which somewhat resembles that of Chelonian rep-
tiles.’” ag
The large bones, which I shall now briefly describe, are
nine in number, consisting of the greater portion of a cranium,
one cervical, one dorsal, and nine anchylosed sacral vertebra,
a part of a rib, an ungual and a corresponding penultimate
phalanx, a large elongated bone, which I assume to be a

scapula, and an interesting little oval bone, doubtless a
tracheal ring. The bones are of a yellowish cream colour,
light and spongy from the loss of animal matter, but all in a
good state of preservation. There are none of the mandibular
or facial bones attached to the cranium, a part of the pre-
sphenoid, and the whole of the left postorbital process of the
frontal bone is broken off, and there is likewise a slight ex-
foliation at the supraoccipital and paroccipital ridges, ex-
posing the remarkably cancellous structure of the cranium.
In the skull described by Professor Owen as typical of the
genus Dinornis, and referred to D. casuarinus, it is stated,
* that the cranial peculiarities of the great extinct wingless
birds are exaggerated in the typical genus, especially the
downward development and abrupt descent of the basioccipital
and basisphenoid, and the forward inclination of the occipital
surface, which makes the occipital condyle the centre of the
hinder surface of the skull, and places the occipital foramen
in the upper half. That the occipital condyle is supported on
a short thick peduncle, and impressed by a subcentrie pit,
whilst the longest diameter of the foramen magnum is in the
vertical direction.” These characters do not correspond with
the skull found in the limestone cave near Rotomarrama.
The cranial peculiarities of the genus Palapteryx are said
to be “‘ the minor development of the basioccipital and basi-
sphenoid downwards in comparison with that in Dinornis
proper; a higher position of the precondyloid foramina, and
their separation from the carotid canals, the square platform
of the basisphenoid, the less development of the paroccipitals,
and great development of the mastoids and olfactory cham-
bers, and especially in the large and single oblong depression
beneath the mastoid, for the single superior condyle of the
tympanic bone.” In his description of the skull of Palapterya
gerenoides, in the collection of Mr Mantell, Professor Owen
says, “it agrees with those assigned to Palapteryx in all the
characters by which they differ from the cranium assumed to
belong to Dinornis proper.”
The general construction, measurements, and details of the
skull of P. geranoides, agree in several particulars with the
Rotomarrama cranium; and in the remarks which I have to
168 Proceedings of the Royal Physical Society.
make upon it, I shall adopt the comparisons made by Professor
Owen on the typical skull of the genus Palapteryx. The
breadth across the mastoid processes in the mutilated cranium
from Rotomarrama is 27’th inches ; the length of the cranium,
measured from the upper part of the foramen magnum to the
anterior extremity of the frontal bone, is 3,3,th inches; the
breadth across the postorbital processes is 27th inches; the
breadth across the temporal fosse is 1,%;ths of an inch. The
vertical diameter, from the supraoccipital ridge to the basi-
sphenoid, is 1,7;ths of an inch. The transverse diameter of
the occipital foramen is nearly ths of an inch. The breadth
across the paroecipitals is 24 inches. The sutures of the skull
are entirely obliterated ; and from the well marked muscular
impressions and rugose surface, there is no doubt that it be-
longed to an old bird. The occipital foramen is subeireular,
and broadest transversely; the descending basioccipital is
impressed by a shallow pit, divided by a slight median ridge,
and bounded below by the straight posterior border of the
basisphenoid platform, the outer angles of which are large
round tuberosities. The precondyloid foramina are situated
at the upper and. back part of the basisphenoidal protuber-
ances, midway between the outer edge of the paroceipital ridge
and foramen magnum, and raised to a level with the lower
border of the occipital condyle. The precondyloid foramina
pass obliquely upwards and inwards into the cranium, and
there are two small pits at the inner and upper edge, nearer
the occipital condyle. The paroccipital ridges, partly broken
in this specimen, are of a semilunar form, and separated by a
notch from the basisphenoidal protuberances. The canal for
the carotid artery is seen grooving the sides of the sphenoidal
platform, winding round the outer part of the base of the
sphenoidal protuberances, penetrating the basisphenoid, just in
front of the lower edge of the paroccipital ridges, and entering
the cranium by the aperture common to the precondyloid
foramina internally. The occipital region is divided into two
parts by a broad median vertical ridge, with two strongly
marked depressions on each side ; but the subdivision, “ slightly
indicated by the bending down of the supraoccipital ridge,”
in Professor Owen’s description of P. gerenoides, is not

observable. The anterior angles of the basisphenoidal platform
are formed by short, thick, outstanding pterygoid processes,
with flat oblique articular surfaces for the abutment of the
true pterygoids. The presphenoidal rostrum passes forwards
from the middle of the basisphenoidal platform to the posterior
wall of the nasal chambers, and there is a well marked de-
pression on each side, beneath the optic holes, running back-
wards at the outside of the pterygoid processes. The foramen
ovale is situated in the middle of the alisphenoid, halfway
between the pterygoid process and glenoid cavity, with its
long axis in a vertical direction. The mastoid process is half
an inch in length, compressed laterally, and extends obliquely
from without inwards and backwards, with a large single
oblong glenoid cavity at the inner side. There is a deep pit
between the inner and back part of the glenoid cavity and
posterior root of the mastoid process. The deep temporal
fossee lie between the mastoid and postorbital processes, the
lower points of the latter being on a level with the former.
The distance between the postorbital and antorbital process
is Linch and ths. There is a small oval pit beneath the
antorbital processes, the long axis of which runs obliquely
from before backwards and inwards. The olfactory chambers
reach backwards nearly three-fourths of the length of the
orbital cavities. There are two large broad anterior hori-
zontal divisions, and two narrow posterior ventrical olfactory
chambers, separated by a slight lateral inflexion of bone at
the posterior third of the chambers, and not by a “ transverse
ridge,” as in P. geranoides. The anterior chambers are
partly roofed over by the prefrontals, wedged in between the
anterior extremity of the frontal bones, but principally by the
frontals. The posterior divisions of the olfactory chambers
are chiefly formed by the orbitosphenoid, ethmoid, and frontal
bones. The olfactory foramina and radiating grooves are re-
markably distinct, especially at the back part of the anterior
larger division of the olfactory chambers.
There is a mutilated cranium of a Palapteryx, which was
sent to Professor Owen by the Rev. W. Cotton, from the
North Island of New Zealand, described and figured in the
Third Volume of the “ Trans. of the Zool. Soc.,” p. 360 (PI.
170 Proceedings of the Royal Physical Society.
lv., figs. 4 and 5), without any specific name assigned to it,
which is closely allied to, if it be not identical with, the Roto-
marrama cranium. It is said to be ‘* equal in size to that of
Dinornis casuarinus, and, from the presence of the left post-
orbital process, to furnish another mark of difference from
the cranial structure of Dinornis proper—namely, the non-
union of the postfrontal with the mastoid.” Again, he says,
“ The olfactory chambers are broader behind than P. gera-
noides, and had not the transverse ridge: the frontals broader
and flatter between the antorbital processes: the temporal de-
pressions are relatively larger, and are traversed by a subver-
tical ridge—differences which indicate the specific distinction of
the birds to which these nearly equal-sized crania belonged.”
The neural canal in the cervical, dorsal, and sacral vertebre
corresponds in size with the foramen magnum in the cranium
found along with these bones, so that there can be little doubt
that these specimens all belong to one individual.
The body of the cervical vertebra is three inches in length ;
and the transverse diameter of its anterior and posterior arti-
culating surfaces measures exactly two inches. From the
rudimental form of the spinous process above, and the con-
dition of the heemapophysis below, compared with those in the
emeu, this appears to be one of the posterior cervical vertebre,
where the spinous process is least developed—probably the
fifteenth or sixteenth reckoning backwards.
The body of the dorsal vertebra is an inch and a half in
length, the transverse diameter at the anterior articulating
surface is two inches, and that of the posterior articulating
surface an inch and ,%;ths. The costal depression is an inch
in length, and half an inch from side to side at the middle
and broadest part, situated at the upper and fore part of the
body of the vertebra. ‘There is a smaller articulating surface
for the tubercle of the rib at the under and back part of the
transverse protuberance. The height from the base of the
body posteriorly to the tip of the spinous process is five inches.
There is a large pneumatic foramen at the base of each trans-
verse protuberance, which almost penetrates into the neural
canal, the intervening space being translucent. The shortness

the emeu, and the length of the spinous process, with its in-
clination forwards, where it abuts against the compressed iliac
bones, render it probable that this vertebra had a similar posi-
tion in the skeleton to which it belonged.
The length of the nine anchylosed sacral vertebree 1s four
inches; the height of the anterior sacral vertebra, measured
from the base to the upper part of the coalesced spinous ridge,
is three inches. The bodies of the first two sacral vertebre
are partly separate, the rest are completely anchylosed. The
first five sacral vertebree are furnished with upper and lower
transverse processes. The last four are destitute of a lower
transverse process. ‘There is a distinct foramen for the exit
of the sensory and motor nerves, as in other birds; the ostrich
is the only exception to this rule with which Professor Owen
is acquainted. The broken portion of a rib measures 33
inches, and 1,8,th inch transversely, at the broadest part.
From analogy with those in the skeleton of the emeu, it
appears to have been broken off below the head and tubercle
of the third or fourth rib on the right side. The two pha-
langeal bones are each nearly two inches in length, some-
what compressed laterally, and rounded above. ‘There is a
longitudinal groove at each side of the ungual phalanx, and a
well marked impression at each side of the anterior articulat-
ing surface of the penultimate phalanx. The phalangeal
bones are double the size of those of the middle toe in the
skeleton of the emeu, but less than those in the ostrich. The
bone, which I assume to be a scapula, is 9 inches in length,
with a circumference of 63 inches at the articulating extre-
mity, where it was incrusted with a layer of calcareous sta-
lagmite, characteristic of limestone-cave specimens. The cir-
cumference at the middle is 3 inches, and 1;5th inch at the
free end. The surface of the bone is marked with oblique
longitudinal striz, decussating in a somewhat irregular manner
from its posterior to its anterior extremity. There are two dis-
tinct impressions at the larger extremity, which may corre-
spond to articulating surfaces for a double condyle of the
humerus, and a broad transverse impression for the articula-
tion of the caracoid in front. This is an interesting addition
to the remains of these extinct birds, as there is no scapula

described by Professor Owen in his ‘“‘ Memoirs on the Di-
nornis.”* The small oval bone found along with the other
bones is evidently a tracheal ring; it measures ;8,ths of an
inch in length, by 7%,ths of an inch in breadth, and is about
roth of an inch in depth.
A portion of a vertebra, which has been deprived of its
calcareous matter by dilute acid, would seem to prove, by the
large amount of residual organic matter, that these fossil bones
are probably of recent origin. |
It is to be hoped that this interesting collection will ulti-
mately assist in the construction of one of the species of Pa-
lapteryx, indicated by Professor Owen from the examination
of detached crania, or founded upon the proportions and ana-
tomical differences of other separate parts, or single bones of
the skeleton.
III. Notice of the “ Anawantrz0” of Old Calabar, Africa; an Animal
belonging to the Famity Lemurina; and apparently to the Genus
Perodicticus, of Bennett. By Joun ALExanpDER Smitu, M.D.
The interesting little animal (now exhibited) was given
to me by Mr William Oliphant, who received it some time ago
from the Rev. Alexander Robb, one of the U. P. missionaries
at Old Calabar. The following extract from a letter, dated
Old Calabar, Ist December 1859, gives some details concern-
ing it:—‘‘I was at Creek Town yesterday, and received from
‘King Eyo Honesty’ a small bush animal; or, as the Krumen
call it, ‘bush meat,’ which I brought with me to give to Mr
Thomson, who is with us for a day or two, as he takes a great
interest in these matters. He, however, advised me to bottle
the animal, and send it to you myself; which, therefore, I now
do with pleasure. We have put it up so that it ought to reach
you in safety. It is in a stoppered bottle, well sealed, and
the bottle is put up in a small tin box wrapped up in our
native grass cloth. It seems to be a lori, or Stenops tardi-
gradus. The Calabar people call it Angwantibo (Angwan
means a farm), but we do not know the etymology of the second

Pinornis in the British Museum, and found to be a left fibula.

part of the word, and cannot say whether it arose from any
habit peculiar to the animal. It lives in trees; but, being
nocturnal, the people know exceedingly little about it. They
cannot tell what it eats. A lad whom I asked said that he
lived in the house, and zé lived in the bush; how, then, could
he know anything about it? My Krumen also recognised it
as a countryman of theirs. They consider the. one sent as a
young one; and say that in their country it grows to the size
of a common puss. Probably theirs is a different animal, but I
cannot tell. They call it Dwdn, and say that it lays down the
law to the other beasts, forbidding them to eat the young frudt
when it begins to form on the trees. If the monkey trans-
gress, the Dwdn seizes him, and holds him there till he dies,—
yea, the monkey rots in his grasp. They say that they are
shot together thus. Ifthe monkey gets the shot, the Dwdan
holds on ; if the Dwain gets the shot, they fall together. The
Krumen say that the Dwdn eats fruit. This is all we know
about it at present ; and their (the Krumen’s) account seems
somewhat fabulous. One of the legs of this specimen is
broken. I will send it by the mail that takes this to your
address.—I am, &c., ALEXANDER Robs.
« P.S.—Since writing the above, I have met a youth
who professes to know about the Angwantibo. He says it
sleeps by day, and eats at night; and that, when full grown,
it is as big as an old cat, and that it eats fruit.”
In a subsequent letter from Mr Robb, dated 28th February,
1860, he says :—‘ I trust you received the Tardigradus sent
a few months ago. Another specimen which I procured I
handed to Mr Thomson, who, I believe, sent it to Mr Murray.”
I have also received from the Rev. H. M. Waddell the fol-
lowing notice, which he had put down in his note-book as
descriptive of the “ Angwdantibo :—An animal of the sloth
kind, lives in trees, hangs on the branches, and eats fruit.
Rather larger, when full grown, than a large cat. Longish
snout, short ears, each foot three long crooked toes and claws,
with a thumb similarly shaped. No tail. Dun colour; cannot
walk on the ground. When set down, crawls a little, falls
over, and rolls itself up in a ball. Inoffensive.”

The animal belongs to the Famity of the Lemurs, LEMURINA
s. Prosimtt, and to the first division of the family which is
distinguished by Van der Hoeven in his valuable ‘‘ Handbook
of Zoology” (translated by the Rev. W. Clark, M.D., London,
1858), as follows :—
PHALANX 1. Nail of the Index alone of the soles incurved,
subulate. Upper incisor teeth four, in pairs.
A. With tarsus not elongate.
Under this great subdivision, it belongs to the
Genus Srenops, Illig. (genera Loris and Nycticebus,
Geoff.)
es teeth 4 canines = molars — Ears short,
rounded. ILyes large, approximate. Index of hand short,
not longer than pollex. Tail short, or none.
Van der Hoeven subdivides the Genus Stenops into the
three following sections :—
(a) Tail short. Index of hand very short, resembling an
unarmed tubercle. (Perodicticus, Bennett.)
(Sp.) Stenops potto, Lemur poito, Gm., Nycticebus potto,
Geoffr., Perodicticus Geofroyi, Benn. Gold Coast of
Guinea. Potto, Bosman.
(b) Tail very short (Nycticebus, Geoffr).
(Sp.) Stenops tardigradus, Auct., Lemur tardigradus, L.
Bengal, Siam, Sumatra, Borneo. Stenops javanicus,
nob., Nycticebus javanicus, Geoftr.
(c) Tail, none (Loris, Geoffr. Body slender; eyes very
large, almost contiguous. Nose acute, sub-ascending),
(Sp.) Stenops gracilis, Loris gracilis, Geoffr., Lemur
tardigradus, L. Ceylon.
The animal, now exhibited, belongs apparently to the first of
these subdivisions (a.); although, with reference to the first
character of this subdivision—that taken from the length of
the tail—it agrees better with, and would therefore seem more
naturally to come under, the second subdivision (6); the dis-
tinguishing and peculiar characteristic, however, of the sub-
division (a) seems to be the undeveloped index finger, and with
this my specimen exactly corresponds. The length of the tail
would appear, therefore, to be rather doubtful as a distinctive

character ; at least, this Angwdntibo seems to be somewhat
intermediate in its characters between the first two subdivi-
sions of the genus Stenops as given by Van der Hoeven, viz.
—(a) Tail short ; index of hand very short, resembling an
unarmed tubercle ; and—(b) Tail very short. The Ang-
wantibo having the index of hand very short, resembling an
unarmed tubercle ; and also, the tail very short. To include
this animal, the first character of section (a) would require to
be altered to—tail short, or very short ; index of hand very
short, &c. It seems to me, indeed, from the discovery of this
Angwéantibo (assuming it to be a new species), that the
greater or less length of the tail is not sufficiently distinctive
to allow any characters taken simply from it to be used for
the division into sections of the comprehensive genus Stenops
of Van der Hoeven.
The generic character which Van der Hoeven gives of the
GENusS Stenops—index of hand short, not longer than pollex,
in the sections (b) and (e), or the equivalent GENERA Nyctice-
bus, Geoff., and Loris, Geoff.—from the examination I have
been able to make of these animals, appears to be due to the
smaller relative size of the metacarpal bone, and the phalanges
of the index finger, which are THREE in number, as in all
the other fingers (eacept the thumb). In the Potto, however,
and this Angwantibo (as will be afterwards described), which
fall under his section (a), and the GENUS Perodicticus, Benn,
the character of index of hand very short, resembling an
unarmed tubercle, is due, not only to the small relative size
of the bones of that finger, but also to the presence of only
TWO very small phalanges (the same number as in the thumb),
the other fingers having three. This anatomical difference
forms a good distinction or character between section (a),
the Genus Perodicticus, Benn., and the other Genera, which
Van der Hoeven has also included in his great Genus
Stenops.
The only species noticed by Van der Hoeven under sec-
tion (a) of his genus Stenops, and, as far as I am aware,
the only one known, is the Stenops potto or Perodicticus
Geofroyi of Bennett, and it, like this Angwadntibo, is a native
of Africa; the other described Genera, or species of Van der
176 Proceedings of the Royal Physical Society.
Hoeven’s Genus Stenops, are inhabitants of Asia, the East
Indies, &c. Wan der Hoeven, in his description of this
species, the Stenops potto or Aposou, says—“ The Aposo or
Aposou of the negroes of the Gold Coast of Guinea is a noc-
turnal animal, which sleeps on trees and lives on fruits. The
Spinous processes of the last five cervical and of the first two
dorsal vertebre are long, and pierce through the hairy in-
tegument of the back, with a weak, horny covering. Professor
Halbertsma first drew my attention to this peculiarity, which
I have observed in two specimens.”
On referring to the description of this same species (the
Potto), placed under the Genus Perodiclicus, and named
P. Geoffroyi, by Mr E. T. Bennett, which is published in
the “ Proceedings of the Committee of Science of the Zoo-
logical Society of London,” for 26th July 1831 (Part I.,
1830-81). I find the animal now exhibited agrees with
the general characters given there of the Genus (correcting
the mistake of considering the projecting teeth in the front
of the lower jaw as being all incisors, instead of both inci-
sors and canines, according to the present view; and there-
fore the incisors only four in number, and not six, as Mr
Bennett described them). To which I would add, as addi-
tional characters of the Genus Perodicticus—tail short, or
very short; index of hand very short, resembling an un-
armed tubercle—supporied by small metacarpal bone, and
only TWO small phalanges. The Angwéntibo seems to differ,
however, from the details given of the species which he
describes,—the measurements of the Poito, or P. Geofroyi,
given by Bennett, being, “length of head 2 inches and ths,
of the body 6 inches; of the tail 1 inch ,&ths, or, including
the hair, 2 inches 3% ths ;”? whereas, in my specimen, the whole
length, from point of muzzle to extremity of tail, is about
103 inches; the tail being only } of an inch in length, or,
including the hair, which is about + of an inch long, only $
an inch. The animal described by Bennett was immature,
its dentition not being perfect; in the one now exhibited,
the dentition is perfect. There seems to be other slight dif-
ferences between the Potto and the Angwdntibo, in the
colour of the hair as well as in the relative size or propor-

tions of the body and limbs, which I shall afterwards notice
in describing this specimen; and while at present unable
to procure various works for reference, or a specimen of the
Potto itself for examination, and therefore in want of more
information on the subject, I am inclined to consider this
specimen of the Angweantibo as being a mature individual,
and probably forming another species of the same genus, and
one that, so far as I am aware, has not before been described,
I therefore, from the locality where it was found, give it pro-
visionally the name of the Stenops, or Perodicticus Cala-
barensis.
The Potto, or Perodicticus Geofroyi,isfound at Sierra Leone,
a region of the African coast, at some distance from Old Calabar.
Itis also known by a different name, being the Aposo or Aposou
of the Gold Coast. The letters of the missionaries (from which
extracts were given at the commencement of this communica-
tion) seem to indicate the possible existence of more than one
species, probably of allied animals—the Dwan of the Krumen,
and this, the smaller Angwantibo of the natives of Old Cala-
bar. Whether the Dwan and the Aposow are the same, or
different species, I am unable to determine: they probably
bear a considerable resemblance to one another. From the
great variety in size, however, of the animals referred to in
these letters, I am at present inclined to believe there
may probably be two, if not three, distinct species,—the
Aposou, the Dwan, and the Angwantibo,—the Dwan being
perhaps the largest in size.
Description ofthe ANGwAntTIBO (from specimen in spirits:)—
Perodicticus Calabarensis (Mih1)—above, yellowish-brown;
the roots of hair dark gray; below, paler, in some parts
nearly white; hair wool-like; length from muzzle to point
of tail, 103 inches ; tail very short, (about th of an inch in
length). ,
Proximal phalanges of both hands and feet (not including
the pollex) united together by the integuments ; the two distal
phalanges being free.*
* A hand of the Potto, figured in “Cuvier’s Animal Kingdom’’—London,
178 Proceedings of the Royal Physical Society.
The Angwéntibo is covered with a thick and long wool-
like hair, which becomes short and thin on the face and on the
extremities, the inner sides of the fore and hind hands being free
from hair. The hair is of a dark gray colour at the base, and
the upper third or so of its length is of a light brown or fawn
colour, the terminal points being of a darker brown; this is
the general character of the fur of the upper parts of the body
and limbs. The face in front of the eyes is rather darker in
colour, but the sides of the head are lighter, and the chin
and throat are nearly white. The inner surface of the limbs
is also lighter, as well as the whole under surface of the
body, the gray hairs having their distal half of a light fawn
colour, and in some places nearly white. The specimen having
been for a long time preserved in spirits, makes it a little diffi-
cult to get at the minute details of colour. There are no
stripes or markings on the back, or other parts of the body,
to be observed on this animal, as on the Stenops tardigradus
of the East Indies ; its general appearance being more uniform
over the surface, although somewhat mottled in character, from
the hair varying in colour at base and apex.
The Bopy of the Angwantibo is slender, and measures 103
inches in length from the point of the muzzle to the extremity
of the very short tail, which is completely hid in the long fur
of the body, and measures only about ith of an inch in length.
This animal is a male; the penis, which is supported appa-
rently by a small bone, projecting upwards and forwards from
the rounded scrotum.
The HEAD is oval and rounded, tapering rapidly in front
of the eyes; the muzzle protruded, full or blunt, and rather
prominent. The breadth of the head, in front of the ears,
is about 14 inch; in front of the eyes, about 3ths of an inch.
The length from the mesian line of the nose to the ante-
rior part of meatus of ear is 1? inches; from point of nose to
anterior angle of the eye is $ths of an inch; from anterior
angle of eye to front of opening of ear, 14 inch,—the total
length of head from muzzle, to back part, being nearly 24

tion of the first phalanges, but three distinct phalanges are figured to each of
the fingers.

inches. The Eyes are rather full and large, the opening of
the lids measuring 4 an inch in length ; the distance between
the eyes at their anterior angles is} an inch. They are rather
prominent forwards, and very slightly lateral. The Kars are
erect and patulous, rather large, and rounded in outline, with-
out emarginations, measuring about 3ths of an inch across
from before backwards, and also from above downwards ;
they seem to be naked internally, and slightly covered with
short hair externally. In this specimen they are nearly
naked, especially on the inner surface. There are two
transverse, abrupt, parallel, projecting ridges of cartilage,
each measuring ;4,ths of an inch in length, in the free
cartilage above the external opening of the meatus. The
external openings of the Nostrits are rather lateral, and
are sinuous, curved upwards and inwards toward the mesian
line of the full and rounded snout; and there is a groove
between them, running down to the front of the upper lip.
The ToncuE is long, and rounded in front, rather rough,
being covered with small papille. Immediately below the
tongue is the projecting lamina, covered with a horny cuticle,
and resembling a smaller, bird-like tongue, which springs
from the frenum and projects forwards, about 2ths of an
inch in length. It 1s free at its edges, and at its point,
which projects about Jih of an inch; reaching to within
ith of an inch of the point of the tongue itself. This horny
lamina measures about ith of an inch in breadth across its
root or base, and about Jih of an inch across its free or front
exurvemity, which is divided into nine sharp terminal points
or filaments. The P. Geofvoyi is described by Bennett as
having this horny lamina terminating in about six filaments.
It is diiicult to understand the use of this strange supple-
mentary horny, bird-like tongue, or expansion of the frenum,
with its pointed terminal filaments, in an animal stated to feed
on fruit; it would seem rather to be some sort of additional
assistance towards capturing or killing an insect prey; but,
in any view, its use seems to be very obscure. Below the
tongue and this supplementary organ, the mucous membrane
lining the floor of the mouth has a slightly free margin pro-
jecting along the sides of the gums of the lower jaw ; in which,

apparently, the ducts of the submaxillary gland (Wharton’s
ducts) open into the mouth.
The NEcK is rather short and slender. There is no ap-
pearance on the back of the neck in this specimen “of the

dorsal, and are bare of hair, or naked, on the palmar surface.
The thumb is much larger than any of the other fingers, to
which it is opposed. There is a large rounded, fleshy, and
horny tubercle, nearly 3th of an inch broad at its base,
which projects about 3th of an inch from the base of the
thumb, on the inner side (next the centre of hand). Im-
mediately opposed to it, and of equal size, or a very little
larger, is another apparently simple tubercle, rising from the
outer side (next thumb), of the base of the clustered fingers
(see * fig. 1); this however, is the rudimentary index finger,
its free extremity projecting only about Ath of an inch. It
is supported by a short metacarpal bone, with a full and ~
rounded extremity, to which are attached two small or
7

rudimentary phalanges; each of the other fingers (not
including the thumb), having three. This rudimentary
index finger has no nail; there is simply a minute mark-
ing, like a cicatrix, or rather a mere short, depressed,
smooth line, an indication of where a nail should be.
The nails of the thumb and other fingers are all thin,
flat, and rounded or ovate, like those of the human hand,
and are not extended beyond the points of the fingers. The
remaining three fingers are slender and prolonged, and the first
phalanges are all conjoined by the integuments, the two distal
phalanges of each finger alone being free. The index or second
finger (considering the thumb as a finger) is, as already describ-
ed, merely like a tubercle rising at the base of the others. The
third finger is the smallest of the other three fingers, and also
the shortest ; the fourth (or middle of the developed fingers)
is the longest ; and the fifth, or last, is longer than the third.
The hands are each divided into two opposing portions: the
thumb, with the tubercle at its base, being opposed to the other
fingers with the tubercle-like index at their base; the thumb
itself being opposed to the fourth, the middle or longest of the
fingers.
The posterior hands or feet (see fig. 2, which also shows
the length of the tarsus) are rather larger and stronger than
the anterior ones, and are each divided into two opposing por-
tions ; the one consisting of the thumb, with a large, rounded,
fleshy tubercle projecting from the inner side of its base, as in
the fore hand; and the other portion, formed of the remaining
four fingers, the first phalanges of which are also conjoined,
being covered by the integuments, as in the hand. There
is a comparatively smaller fleshy tubercle, somewhat like the
undeveloped index finger of the fore hand, projecting from the
outer side of their base, which is opposed to the tubercle at
the base of the thumb. It is not supported by any bone, but
is merely a horny and fleshy projection like that on the base
of the thumb. The nails of the thumb and fingers are thin,
flat, and rounded or ovate in form, like those of the fore hand,
with the exception of that of the second finger (counting the
_thumb as the first), which is narrow, convex, sharp-pointed, and
claw-like, and extends nearly to the point of the third finger,

this claw-like nail, indeed, constitutes one of the distinctive
characters of the Famity. In the P?. Geofroyi of Bennett,
the claw-like nail on the second finger appears to be 1 inch
and ths in length (the finger being stated to measure ;,ths
of an inch, or, including the nail, 2 inches },ths); whereas,
in the Angwdntibo, the whole length of the free extremity of
the finger is half an inch, including the claw-like nail, which
measures rather less than a quarter of an inch.
The hands and feet have been already mentioned, as
being each divided into opposing portions. They remind one
of the zygodactylic feet of the Climbing-Birds; and this
character, taken along with the existence of the rete mira-
bile of the limbs (the tortuous and anastomosing plexuses
of vessels, which exist in this animal, as well as in others
of its class), and the arboreal habits of the creature (for
so completely does it dwell among the branches of trees,
that it is stated by one of the missionaries to be scarcely
able to walk on the ground), all seem to tell of long-continued
muscular action, of a capability of taking a safe, sure,
and long-enduring hold; and, probably, like others of its
class, of a stealthy step, which may enable it to steal upon,
and hold fast, an active and vigilant prey. The incident
mentioned already by the missionaries, of the Dwdn seizing
animals like the monkey, is very curious; as we cannot
help thinking they must be seized and held fast for a some-
what different purpose than merely to prevent them destroy-
ing the young and unripe fruit, on which they both are said
to feed. The dentition of the Angwantibo, to be afterwards
detailed, would make us incline to the belief of its food
being of a more mixed character than simply fruit, and that it
probably included at least insects or their larve, for the cap-
ture of which the peculiarly complicated lingual apparatus may
afford special facilities ; or possibly, the smaller birds, which,
from its nocturnal habits, it may also steal upon and capture,
while they are quietly roosting among the branches of the
trees. The structure of the feet, however, and the apposition
of the thumb to the middle of the fingers, seem to show an
adaptation for seizing forcibly the twigs of trees, rather than
for the purpose of capturing a prey.

MICROSCOPIC STRUCTURE OF THE Hair OF ANGWANTIBO.—
It occurred to me to examine through the microscope some of
the hairs of this little animal ; and I was much struck by their
186 Proceedings of the Royal Physical Society.
apparent variety and beautiful cellular structure. Plucking
a few at random from the upper surface of the body, I found
I had got three different varieties: large flattened hairs,
showing a combined series of cells; smaller hairs, containing
a single series of cells; and each displaying the external or
epithelial coating of the hair, which forms a series of over-
lapping margins or scales, their free edges being directed to-
wards the points of the hair; and, lastly, small bent or curved
solid horny-like hairs, with this overlapping external coating
developed here and there into large hook-like processes or spines.
At my request, my friend Dr T. Strethill Wright made a
minute microscopical examination of these hairs, and sketched
the accompanying careful drawings (see Plate VIII.), which
show very well their beautiful structure. Dr Wright used
simply water in examining some of the hair; and this fluid
entering by the cut extremities, and permeating the hair
thoroughly, distinctly revived. and exhibited their internal
cell structure. In the smaller-sized hair, containing only
one series of cells, the cells are found to have an hour-
glass contraction in the middle, the lower half of the cell con-
taining the colouring-matter of the hair, and the upper part of
the cell displaying a distinct central nucleus, the existence of
which, at least in the body of the hair, is a fact which was new
to both of us, if not altogether new to microscopists in general ?
These nuclei were also beautifully seen in the cells of the
larger hairs. Dr Wright has figured (Plate VIII. fig. 4)
the peculiar appearance which some of the hairs displayed, of
black bars, arranged in a somewhat parallel manner, or zig-
zagging from one extremity to the other, in the central
portions of the bodies of the hair; for the lower, and upper
portions of all the hairs, showed no cell cavities, being formed
apparently of solid structure. These black bands were due to
some of the uncut hairs being mounted in turpentine or balsam,
which did not permeate the hair like the water, but obscured
their true structure altogether, by enclosing the air as a black
band, which was varied both in shape and in contiguity, in
the lacerated cells of the hair.
Thick hair or fur of a cellular structure containing thus
enclosed a considerable amount of atmospheric air, a bad con-
ductor of heat, and therefore useful in preventing the rapid

cooling of the body of the animal, has been believed to be
peculiarly adapted as a covering for animals inhabiting cold
climates ; it seems, however, to be not inappropriately found on
this little animal, which is stated to search for its food by
night, and is therefore exposed to the damp and cold which
occur at night in even a tropical forest.
Annexed is Dr Wright's detailed description of Plate VIII.

The Society may think Ihave entered rather too much into
minute details of description. My reason for doing so, is to
leave no doubt on the mind of any one, who may wish to make
comparisons between this Angwantibo and any other indivi-
dual of the genus, as to the special animal I have attempted to
describe ; and, for preservation, it is my intention to deposit the
specimen in the Natural History Museum of the University.
Since the preceding pages were in type (various unavoidable
circumstances having delayed the publication of these Proceed-
ings), | have been fortunate enough to get this specimen of
the Angwantibo, and my detailed description, compared with
the Potto described by Mr Bennett; and also with other speci-
mens of the Potto in the collections of the British Museum—
my friend, Mr William Carruthers, of the Botanical Depart-
ment of that great national institution, having, at my request,
kindly taken the trouble of examining them.
Mr Carruthers informs me I am correct in my opinion of the
Angwéntibo being a distinct species from the Potto, the Pero-
dicticus Geoffroy? of Bennett; and also that it is a species
apparently unknown to naturalists. 1am therefore at liberty
to designate it the Perodicticus Calabarensis.
188 Proceedings of the Royal Physical Society.
Mr Carruthers says :—“ It is certainly a second species of
Perodicticus. I compared it with two stuffed specimens of the
Potto, and, with the assistance of Dr Gray, determined that
it was new, differing chiefly from P. Geoffroyi in its tubercle-
like tail and large ears. I also got Mr Bennett’s specimen of
the Potto,—which is yet fortunately in spirits,—and have
been able more completely to discriminate the differences.”
At my desire, Mr Carruthers got an artist to make sketches
of the head of Mr Bennett’s specimen of the Potto, and
also of my specimen of the Angwdntibo, to show the vari-
ous differences between them, in a more manifest way than
by any lengthened description; and as both the specimens
have been preserved in spirits, these comparative differences
Fig. 3. Head of Angwantibo
are seen at a glance, no change in the original appear-
ance of either, having been made by any attempt at skin-
ning, or otherwise preparing them for preservation. The
sketches are of the natural size, and Mr Carruthers mentions
they are very accurate, and are drawn without any attempt
to put the hair in its natural position. In this way two things
are gained. First, both specimens are exhibited as they really
are, without any exercise of the imagination of the draughts-
man; and, secondly, the outline of the skull is given in both,
which is of much more importance than the outline of the hair,
in animals where the hair is thick and stands nearly erect.
The annexed woodcut (fig. 3), is the sketch of the head of the
Angwdntibo, the other (fig. 4), that of Mr Bennett’s specimen
of the Potto.
On the Angwantibo of Old Calabar. 189
In pointing out the various specific differences which the
comparison of the two specimens make manifest, Mr Carru-
thers says, in the Angwdntibo the body and limbs are more
slender than in the Potto, and the colour of the hair is
more uniform. The head is longer and narrower, with a more
produced muzzle, larger mouth, and more prominent eyes;
while in the Potto (see woodcut), the head is nearly round,
and has a much less projecting muzzle. Again, the ear is
larger, and directed more upwards and forwards in the Ang-
wantibo; and there are two folds, as already pointed out,
in the inner surface of the ear; while there is only one in
the Potto. The drawings show also the remarkable differ-
ences in the teeth. The teeth in the lower jaw, which
Fig. 4. Head of Potto.
Bennett described as the canines in the Potto, but which
are now considered as pre-molars, are mentioned by him as
having cutting surfaces, both before and behind, they are,
in fact, small, flat, triangular teeth ; whereas in the Ang-
wantibo they are long, rounded, and more canine-looking.
Then the six teeth in the front of the lower jaw, in the Ang-
wantibo, are smali and hyaline, not visible above the under
lip; while in the Potto they are large, prominent, and pro-
jecting (see woodcuts), and of the same colour as the molars.
There is also a very striking difference in the hands of the
two little animals. Mr Carruthers has been good enough to
make the annexed careful sketches, the size of life, of the
hand (fig. 5), and the foot (fig. 6), both belonging to the left

side, of Mr Bennett’s specimen of the Potto, (see woodcut, figs.
o, 6); and on comparing these sketches with those already
given of the Angwdntibo, which, for comparison, I here
repeat (figs. 1, 2), the differences will be seen more clearly
than could be brought out by any description. In the Ang-
wantibo the hands and feet are small, round, and fleshy, with
several large pads; in the Potto they are large, flat, and thin.
In both, as has been already carefully described, the index
fingers of the fore hands are undeveloped ; being represented
in the Angwantibo by a simple tubercle (see * fig. 1.) Inthe
Potto, however, as shown in the drawing, the index is not so
like a mere tubercle, but is more developed, and therefore
more resembling a finger, than in the Angwantibo, (See *
fig. 5.)

ANGWANTIBO.
Mr Carruthers says the tail is perhaps the most striking
distinguishing character. 1 have already in the body of my
paper sufficiently described it.
Mr Carruthers informs me that when comparing the dif-
ferent species of Van der Hoeven’s genus Stenops, in the
British Museum, he was struck with the great diversity of
their general appearance, and wondered at a zoologist like
Van der Hoeven grouping together what appeared to him to
be several well-marked Genera. Indeed, the only explana-
tion that occurred to him was, that Van der Hoeven intended
to give the character of a SuB-FAMILY to his Genus Stenops.
Mr Carruthers tells me, that while comparing the specimens
of these two animals, he had on his table all that has been pub-

lished on the Potto. Bosman’s figure is a grotesque carica-
ture of a fat and lazy animal, having a very faint resemblance
to the Potto. Van der Hoeven gives a drawing of the skull
in the “ Tydschrift voor Nat. Gesch.,” vol. ii. plate i. fig. 3,
and of a young animal, in plate 11.; also a very full account,

sections. First, the true Lemurs, with long tails; second, the
Lorids (stenops), without tails, and with long limbs; and third,
those with very short tails, or almost tail-less, oval or globose
heads, and short fleshy arms. Here he has two genera:

ticze abortus, in tuberculum coarctatus.” And, II. Wyctice-
bus, ‘ Caput globosum, ore conico. Aures in pelle absconditz
occuli magni. Digiti normales.”
I may mention, in conclusion, that I find, since this paper
was in type, that Van der Hoeven made a short communication

on the Potto to the Meeting of the British Association in 1850,
and a second on the anatomy of the Potto in 1860, in which
he refers to a complete monograph of this animal published by
him in 1859, in the seventh volume of the Transactions of the
Royal Academy of Sciences of the Netherlands (Ortleedkun.
dig Ondersock van der Potto van Bosman door F. A. W. Van
Campen Med. Cand. Uit due Platen Amsterdam. 4to, 77 pp.)
Van der Hoeven also details his arrangement of the Lemuride,
published in his ‘«‘ Handbook of Zoology,” and refers again to
the peculiarity in the Potto, “that some of the spinous pro-
cesses of the neck, covered only by a thin corneous epiderm,
pierce through the fur-like prickles. They are those of the
fifth to the last cervical, and of the first two dorsal vertebree.”
These projecting processes are evident, Mr Carruthers informs
me, in Mr Bennett’s specimen, though, probably from its
youth, neither so numerous nor so strongly marked as Van
der Hoeven describes them. In the two stuffed specimens in
the British Museum they cannot be detected, as might have
been expected; as already stated, I could not detect this pecu-
liarity in my specimen of the Angwéantibo.
I have been recently favoured with the following explana-
tion of the name Angwéntibo, from the Rev. Alexander Robb :
—‘‘ The name Angwad-ntibo is compound; the first part is the
same as the name of the domestic cat, which the Calabar
people call Angwa, or Angwa-mbéana—the ng being a very
soft nasal sound. Angwéis probably onomatopoetic, from its
resemblance to the sound of the mew or cry of the cat. The
meaning of ntibo is unknown to me. The Angwéntibo is,
therefore, so named, probably because it is supposed to re-
semble the cat, either in its cry or in some of its habits. We
give this note as a correction of the etymology proposed in
the letter at the beginning of the above paper.”
The Secretary reported that as several communications still
remained in his hands, which he was anxious should not
be allowed to lie over to another Session, he proposed that
another meeting of the Society should be held on Wednesday,
the 9th of May. This proposal was agreed to, and the
Society adjourned.

I. Observations on British Zoophytes. By T. Stretuitt Wricut, M.D.
On Halcampa Fultoni (Strethill Wright), a parasitic Actinia.
The author stated that, in the summer of 1858, he took, by dipping, a
great number of Medusez of the genus Thaumantias, off Granton Pier.
'To the peduncle of one of these was attached 4 small Actinia, about half
an inch in length, and one-eighth of an inch in diameter, From its
general appearance, he considered it to be a young specimen of Actinia
troglodytes, which had been seized by the Medusa, dragged from its
native mud, and brought captive to the surface of the water; but it was
unfortunately lost before he could examine it carefully. In June, his friend,
Mr Fulton of Granton Pier, brought him some specimens of Thauman-
tias, to one of which another Actinia, of the same species as the one he
had before observed, had attached itself by swallowing the peduncle of
the medusa. The body of this Actinia was of a transparent, yellowish-
white colour, and marked by twelve paler lines, indicating the situation
of the longitudinal septa within. The oral dise was oval, and formed by
194 Proceedings of the Royal Physical Society.
the basis of the tentacles and the mouth. The tentacles were twelve in
number, of a rich umber brown colour. About one-half of each from the
- base was marked with five opaque pale-yellow lozenges, and from thence
to the top by four bands of the same pale-yellow colour. The brown
matter consisted of amorphous, pigment granules, the yellow matter of
highly refractive and exceedingly minute molecules, apparently calea-
reous. Hach tentacle was curved backwards, and resembled the abdomen
ofa wasp. The pigment could be forced through the top of the tentacle by
pressure, indicating an opening at that part. The mouth, instead of being
linear, as in the Actinias, tended to assume a quadrangular, or crucial]
form, though the constantly varying shape of the dise rendered a descrip-
tion of it difficult. The stomach was very peculiar, and differed from
that of the Actinias. It was a flat and
obscurely quadrangular sac in transverse
section (fig. 1.) Its angles he should de-
scribe as superior (a), lateral (6), and in-
ferior (c.) The superior angle was con-
nected to the parietes of the body by four
septa (d), the lateral angles each by one
septum (¢), and the inferior angle by two
septa (f) These septa were continued
downwards, as in the actinias, to the lower
extremity of the body, and had their free
edges bordered by a convoluted ciliated
band, furnished with cnide, or thread-cells.
The stomach and parietes were further con-
nected by four intersepta (g), as he should

ovaries, or sper maries, the intersepta not, in which case the reproductive
system of the animal now described agreed in simplicity with that of the
polyp of the Alcyonide, which had only eight septa, each bearing ciliated
bands. The upper part of each of the septa and intersepta was perforated
by an oval opening, so as to give an uninterrupted passage beneath
the tentacles to the circulation of the fluids of the body. By tracing
this passage in. the Lucernarias, he had come to the conclusion that
it was the homologue of the eae canal of the gymnophthalmatous
medusa, The attachments of the stomach thus resembled those of the
same organ in the other Helianthoid and Alcyonian polyps, but in shape
it widely differed from these. In Actinia and Alcyonia the stomach was a
flattened sac, open, and evenly truncated at its lower extremity. In the
animal now described the lower border of the stomach curved gently
downwards from the superior to the lateral angles (fig. 2,a 6), and from
the lateral to the inferior angle it bent deeply and abruptly downwards

downwards, so as to form a beaked process, as shown in the figure. The

thread. When the animal was
separated from the peduncle of the
Medusa, and placed in a dish of
sea-water, it slowly moved from
place to place by the aid of the
tenacious palpocils which studded
the tentacles and upper part of the
body, and alternately filled itself
like a balloon, and emptied itself
by a vermicular contraction of the
parietes, which commenced be-
neath the tentacles, and passed waa a |
backwards. When dilated, it was BRE y | ae

in a funnel-shaped depression,

II. On New Fossil Forms from the Old Red Sandstone of Forfarshire.
By Davin Pagez, Esq. (Specimens of the Fossils were exhibited.
Mr Page next drew attention to some new fossil forms from
the Old Red Sandstone of Forfarshire. These fossils occur in
a bed of highly fissile shale, lying in the course of the Pow-
burn, near the church of Farnell, and belong to the gray tile-
stones, or lowermost series of the system. They consist chiefly
of fishes and crustacea—the former embracing three or four spe-
cies of Diplacanthus, two of Acanthodes, Climatius, Cheira-
canthus, and several forms yet undescribed, the latter being
Pterygotus, Eurypterus, and Kampecaris, with detached plates,
and Parka decipiens. The deposit (discovered some time ago
by the Rev. Mr Mitchell of Ferryden) was now being worked
out under the superintendence of the Rev. Mr Brewster of
Farnell, and Mr Powrie of Reswallie, solely for the fossils—

facility and assistance in the work of excavation. A great
number of specimens had been obtained in beautiful preserva-
tion, as could be seen from those exhibited to the Society,
and geologists might rest assured that every care would be
taken to render these treasures available to the purposes of
science.* Independent of the paleontological value of so
many new and perfect forms, the discovery was of high litho-
logical interest, as enabling geologists to determine with
greater precision the relative ages of the Forfarshire and
Caithness series, both of which had now been proved to be
_ characterised by the same specific forms.
Ill. On the Nidus and Y. oung of Pontobdella muricata, and other An-
nelides. By Cuas. Wittt1am Prac, Esq., Wick. (With Illustrative
Sketches.)
On the 21st January 1859, my colleague, Collector Boyd,
kindly sent me an old oyster shell attached to an oyster,
brought to him from the Frith of Forth, on which he had
observed something strange and unusual. The form was quite
new to me, and although well acquainted with the nests of
many shells and other sea animals, this differed from all I had
previously seen. I found amongst the nests a small annelid, and,
on applying my lens, discovered that it was a young Pontob-
~ della, which I supposed had got in there for shelter. I laid it
carefully aside, and continued my examination, and soon found
a portion of a second worm protruding from the upper part of
one of the nests, and that it, too, was another tiny Pontob-
della. This quite surprised and delighted me. Still, I had
my doubts whether it had not crept into the nest after it had
been accidentally ruptured, and suspected that its errand
was one of felonious intent. I then selected a nest which
appeared to be full and uninjured. On opening it with my
lancet, I found that I had libelled the above-mentioned, for
there, snugly coiled up, was another veritable baby Pontob-
* Several of the fishes referred to by Mr Page have since been figured and
described by Sir Philip Egerton in No. 10 of the “ Decades of the Geological
Survey of Great Britain.” Three of the genera are also figured in Mr Page’s
new work, “Past and Present Life of the Globe.”

della. Here, then, was a discovery! The Pontobdella is so
well known as a parasite on skate and other fishes, that I need
not describe it. Remembering how little was really known
about the propagation and early forms of annelides, and of the
conflicting opinions entertained by various naturalists on the
subject, I felt quite delighted,—some believing that all pass
through many changes, from the egg to the adult state; others
that.there is no change. The tale of the “two travellers”
came into my mind, “both are right and both are wrong,”
and that at any rate an opportunity was afforded me, if ap-
pealed to as an umpire, to decide satisfactorily one point in
the controversy,—namely, that beyond that of growth, the
Pontobdella passes through no change after leaving the egg.
The nests are darkish gray, stout and tough, balloon-shaped,
are deposited in a group, but not in mathematical order.
Although one showed a worm protruding from the top, this
was caused by the accidental rupture of the egg; the natural
opening for the escape of the young is a circular opening on
the side. Each nest contains one worm. The shell having
been long out of the water, all the worms were dead, but in a
good state of preservation ; they, with many of the nests, are
in spirits, and only await the time when some one will demand
them for publication, in the long desiderated history of these
beautiful, but too long neglected creatures. Having given
my decision for the no-change man, I must now turn and side
with those who assert change. From having read many of
the papers, and seen the figures both of the adult and early
stages of annelides, by the late Dr George Johnston, and of
others published in various volumes of the “ Magazine of
Natural History” (unfortunately few of these volumes have
come in my way), and as well from observations of my own,
“ On the luminosity of the sea,” published in the ‘“ Transac-
tions of the Royal Institution of Cornwall for 1849 and
1850,” where I figured two forms of the young of anne-
lides which came under my notice during my researches on
that subject, as well in 1844, when I first discovered the
Nereis bilineata, as a tenant of the same shell with the her-
mit crab,—Pagurus bernhardus,—l saw the eggs of this

dages on each side of its really beautiful parent. Of the
parentage of these eggs there is no doubt; but beyond that
all else about them to me is dark. I algo regret I must leave
those figured at 6 and 7 (sketch exhibited) in the position of
those “whom many fathers share,” from not being able to
affiliate them. ‘The one figured at 6 occurred to me both at
Fowey, in Cornwall, and at Peterhead, in Aberdeenshire. At
the expense, I fear, of being tiresome, I cannot resist the
opportunity of adding, that in the course of my turning up the
stones between tide-marks, after the nests of Lamellaria ten-
taculata, in March 1852, at Wick, I observed bluish masses
of jelly-like matter, in which light yellowish spots showed
through the transparent envelope. At first I took them for
masses of ova of shell, or Nudibranchs; but on examining
one carefully, I observed that at each end of the elongated
mass there was a hole, and I fancied I could see something
move in it. On passing my knife under it, a small dark, olive-
green, iridescent worm, eel-like, glided out. This I secured,
and found it to be one of the Nemertes, probably WV. gracilis,
so abundant under stones, where black, decomposing vegetable
matter is mingled with sand. From year to year ever since I
have noticed these jelly-like masses, with the attendant worms.
Last night (8d May 1860), I found five or six nests of them
under one stone, and as they were farther advanced than
those I first found, instead of the Nemertes being in the centre
of the mass, they lay either close alongside of it, or partly
across it, thus showing attachment to its nest. I have often
transferred these worms and nests to my aquaria, but have
never been able to get the eggs to hatch. As they are gene-
rally on large stones, I am obliged to use force to get a piece
sufficiently small for my purpose; this, added to not being
able to associate them with proper material, and in the posi-
tion they occupy in their native element, will account for
failure. The ova are arranged in two rows, as may be seen
through the glairy mass, and in trefoil-like spots. These
masses are from two to three inches in length, and about one-
fourth of an inch across, and high. They are very tough and
elastic.
Dr T. Strethill Wright stated that he had, in company

with Dr M‘Bain, dredged up the nests of Pontobdella in the
Firth of Forth. Sir, J. Dalzell had figured these nests and
the young in his “ Powers of the Creator,” vol. 11. plate 1,
and well described them in that work. Referring to Mr
Peach's description of the Nidus of Numertes gracilis, Dr
Wright stated that the nests of several annelides might be
found in the pools near Seafield, the eggs of which had been
hatched under his care, and he described the progress of
development in the embryo. He stated that at one stage the
embryo of the annelid exactly resembled that of Cydippe
pomiformis, formerly described by him to the Society.
IV.—WNotice of Snakes and Lizards from Old Calabar. By GrorGE
Logan, Esq., W.S.
During the year 1857, the missionaries in Old Calabar
connected with the United Presbyterian Church in Scotland,
transmitted to some of the Fellows of the Royal Physical
Society a considerable number of specimens of snakes and
lizards, and of other interesting objects in various departments
of natural history. Of the reptiles a portion were sent to
Dr J. E. Gray, of the Zoological Section of the British
Museum, with a request that he would examine and name
them, that they might be described and submitted to this
Society; and if there were any duplicates among them which
would be of service to the Museum, they might be retained.
Dr Gray acknowledged receipt of the specimens transmitted
to him, but he seems to have overlooked or forgotten the
conditions attached to their transmission, as in the spring of
last year (1859) he, upon personal application at the Museum,
only returned six of them named, without any notice of the
remainder. He was then written to, reminding him of the
terms upon which the reptiles were sent to him, and that it
was desirable that a list and description of them should be
submitted to this Society, but no answer was received to
this communication. The British Museum Catalogue, and
the Proceedings of the Zoological Society of London, have
furnished, however, to some extent the information awanting.
The following notice by Dr Gray appears in these Proceedings,
Part xxil., March 1858, page 154:— ‘Mr Logan kindly

sent to me for examination a number of snakes and other
reptiles which had been collected by the missionaries in Old
Calabar. Among several very interesting species I observed
a new genus of the family Boide, which I have great pleasure
in laying before the Society, more especially as it appears to
be the indication of a new tribe in that curious family.
“ This animal belongs to the second section of the family
which is thus characterised :—
“IT. Tail very short, not, or only very slightly, prehensile.
Head indistinct, short.

Carinina, and Tortricina, and therefore I propose to form for
it a tribe (Calabarina) by itself, having the same characters
as the genus.

‘Head small, short, rounded in front, the same size as the
body; muzzle depressed, rounded; labial shields flat, 3 the
hinder small, front moderate ; rostral shield high, large, tri-
angular; frontal shields, three pairs, band-like, subsimilar,
followed by a band-like shield continued from side to side,
which has behind it a small subtrigonal shield on each side,
with a central large triangular shield between them on the
crown. yes surrounded by scales, on the upper edges of the
upper labial shields, and the outer edges of the fourth and
fifth frontal plates, and with one ocular shield in front, and
two smaller behind the eyes; loreal shield single, small;
pupil circular. Nostril lateral, between two small nasal
shields. Body cylindrical. Scales broad, triangular, po-
lished, rather sunken and subrugose in the centre. Ventral
shields very numerous, band-like, transverse, about half as
wide as the diameter of the body. Vent small, with a single
preanal shield. Spurs large, distinct. Tail short, as thick
as the body, blunt, and rounded atthe end. Subcaudal shields
broad, band-like, one-rowed, like the ventral shields.
‘T think it probable, when some other specimens have been
examined, that the band-like shield extending across from the
upper edge of each eye will be found to be composed of three
shields like the band behind it, which are here united into

shields over each eye, having in the middle between them two
triangular parietal shields.

or in groups on the back and sides; ventral shields grayish.

“Since this paper was read, I have discovered a young
specimen of this boa among the specimens from the Zoological
Society, which they had received from Fernando Po. It is
about half the length and diameter of the specimen from Old
Calabar. It has the head shields more uniform, and as I sup-
posed they might be when I described that specimen. It has
three pairs of band-like frontal shields over the forehead, a
rather large parietal shield behind them on the crown of the
head, and two small subequal superciliary shields between the
outer edge of the parietal and the eye, on each side a narrow
transverse band-like central shield behind, and rather broader
than the parietal shield, with a small scale-like shield, like
those on the neck behind, and on the sides of 1t.”’
Although the above descriptions have thus already appeared
in the proceedings of another Society, there has been no hesi-
tation in fully quoting them, not perhaps because they ought
rightfully to have first been given in the Proceedings of this
Society, but that they are of sufficient interest to entitle them
to repetition. |
Of the other specimens of reptiles returned by Dr Gray, that
labelled Ahewitulla Chenonii will be found noticed in a most
useful list prépared by him, at p. 161 of the above-mentioned
part of the Zoological Society’s Proceedings, No. 68 of the list,
under the leading name of Ahetulla Irreqularis, together
with its synonyms; the localities assigned being Gambia,
Fantee, and the Gold Coast. Another of the specimens will
be found noticed in the same list, immediately following, under
the name Ahetulla Smaragdina, together with its synonyms,

the localities assigned being Ashantee and Guinea. The
next specimen, Causus Rhombeatus, will also be found in Dr
Gray’s list, p. 163, No. 86, with its synonyms (Hab. West
Africa; Gold Coast, Liberia, South Africa); but it is, more
fully described in the catalogue of reptiles of the British
Museum, 1844 (Snakes, p. 33). Of this snake the British
Museum possesses four. The specimen named Boodon Geo-
metricus will be found, with its synonyms, in Dr Gray’s list,
p- 159, No. 42, under the name Bowdon Geometricus, Hab.
West Africa; and the specimen named Onychocephalus
Liberianus will be found with the single synonym Onycho-
cephalus Liberiensis, under the name Onychopsis Liberiensis,
in Dr Gray’s list, p. 157, No. 18; Hab. Liberia, Calabar.
The last remaining specimen to be noticed is a lizard,
Tiliqua Fernandii, described in the British Museum Cata-
logue (p. 110, Lizards) as Tiliqua Fernandi—the Fernando
Po Tiliqua—of which an interesting account has already
been given to this Society in a paper by Mr Andrew Murray,
at p. 415 of the first volume of its Proceedings. The oblique
cross brown bands along the brown sides should be bright
scarlet or vermilion, but stuffed or preserved specimens seem
to lose this brilliant colour, as it is not to be seen in the pre-
sent specimen, although otherwise in excellent preservation.
V. On the Stlicification of Organic Bodies. By ALEXANDER Bryson, Esq.,
F.R.S.E.
The solution and deposition of silica has become a very im-
portant question, not only to the mineralogist, but to the
physical geologist. Whilst the mineralogist has speculated
on the forms of silicious minerals and fossils, he generally
has arrived d prior? at the conclusion that they were of aqueous
origin; the geologist, on the other hand, has assumed them
mostly as due to igneous action. M. Brogniart was the first
to point out the true theory of the silicification in fossil woods,
in an able paper published in the “ Dictionnaire d’ Histoire
Naturelle.” In 1828 Von Buch communicated a paper to the
Academy of Sciences of Berlin, in which he boldly asserts that
the silicifying process never immediately attacks the calcare-
ous shell; that it develops itself only upon the organic sub-
On the Silicification of Organic Bodies. 203
stance of the animal, or the organic matter contained in the
shell, and that where such organic substance is not present
there, no silicifying takes place. In support of these views
of Von Buch, it may be remarked, that wherever shells are
found embedded in a silicious matrix, they are generally en-
tirely converted into silica, no doubt owing to the large quan-
tity of animal matter contained in them before silicification
took place. In no instance could I find a trace of calcareous
matter remaining, clearly showing that either a chemical
change had taken place, or a mechanical substitution of the
silica for the whole calcareous matter.
In further proof of Von Buch’s theory, I may quote a paper
by Dr Bowerbank on a zoophyte (Alcyonites parasiticum)
which he found enclosed in an agate. The interest attached
to this paper is, that while we have no evidence of the time
required for the silicification of calcareous bodies, and of
woods and horny substances here, we have complete evidence
of the rapidity of the change from the slight amount of the de-
composition of so tender a zoophyte as an Alcyonium. On this
point Dr Bowerbank remarks, ‘‘ Nearly the whole of the
animal within the agate is in a beautiful state of preservation,
but there are a few spots which present evidence of the com-
mencement of decomposition by the detachment of groups of
cells from the mass of the polypidom ; in these cases the re-
mains of the tentacles, as might be expected, are very rarely
to be seen, and the disrupted mass is totally without a sponge
fibre. The envelopment of a tooth, or of hard calcareous bodies,
such as shells, afford no definite information regarding the
time necessary to accomplish such an operation. The invest-
ment even of such bodies as the rigid endurable horny fibres
of that tribe of sponges which are usually to be observed em-
bedded in flint, cherts, and moss agates gives also a consider-
able range of time to accomplish the fossilisation ; but when
we see such a soft and perishable substance as the fleshy body
of the living Alcyonide, and such delicate organs as the ten-
tacula of the polypes thus preserved with such evident appear-
ances of freshness and perfection, I own it excites in me the
greatest astonishment that there should have been so rapid a
deposit of silicious matter as must evidently have taken place
204 Proceedings of the Royal Physical Society.
thus to entomb the animal in such a condition as proves that
at the utmost but a few days must have elapsed before it was
so far encrusted as to completely preserve the form and posi-
tion of the animal, not by a sudden immersion in suppositi-
tious silicious paste, impounding it instantly in its full
vigour, but after by a slow and gradual decease; for this
condition which I have described of semi-protrusion of the
tentacula is that with which every one acquainted with recent
zoophytes in a living condition is so familiar as an indication
of slow and undisturbed death by exhaustion. In this condi-
tion of semi-protrusion of the tentacula I have seen the
animals of Alcyonium digitatum, Alcyonidium parasiticum,
Caryophyllacea Smithii, and numerous species of Sertularia
and other zoophytes die, if allowed to do so without interfer-
ence; but if touched or disturbed, the tentacula are slowly
withdrawn, and never again extended. It does not appear to
me to be necessary, for the production of a fossil, that the
whole of the silex should have been deposited immediately.
We may readily imagine, that after the rapid deposition of the
first portion induced by the full exposure of the animal matter,
and the consequently strong elective attraction exerted by the
animal for the earthy particles, that the remainder of the de-
posit—the filling up of the interstices of the network—would be
more slowly and regularly completed in accordance with the
laws of crystallisation, as we find that from the surface of this
animal there are the same series of crops of radiating calce-
donic crystals that characterise the structure of the great mass
of the moss agates which I have described in my paper on
those bodies, published in the “‘ Annals and Magazine of
Natural History,” vol. x. page 9.
This prismatic semi-crystallisation, if we may reason from
analogies afforded by the phenomena of crystallisation dis-
played by salts formed by acids with earthy or metallic bases,
is a rapid, and perhaps irregular operation, compared with the
slow formation of the regular and well-defined crystals of the re-
spective substances under consideration, and which crystals are
probably produced without the interference of any other agent
than that which is necessary for their own construction. The
specimens of fossil wood now shown prove that during the
Or
On the Silicification of Organic Bodies. 20
process of silicification considerable ruptures of the vessels
had taken place, and that the wood was in a recent state at
the time of fossilisation. I may further state, that the late
Robert Brown showed me a section of silicified wood which
fully corroborated the reasoning of Dr Bowerbank, as it bore
distinct evidence of having been alive, and struggling to live,
during the process of silicification. That the solution of
silica in the humid way was not so difficult as many geologists
supposed, chemists’ experiments all tend to prove that it is
soluble in a large degree. I especially refer to the experi-
ments of De la Rue, who succeeded in obtaining minute crys-
tals of quartz by an aqueous method. De la Rue found that
the gaseous body, fluoride of silicon (Si F,), is decomposed
by contact with water, one-third of the silicic acid being de-
posited in the form of jelly and silicated hydrofluoric acid
(3HF + 28iF,) produced: thus, 3 (SiF, + 3 (110) = 810,
(which deposits) + 3HF + 28iF3 (which remains in solu-
tion).
The deposited silica is extremely soluble in water, and he
observed that the silicated-hydrofluoric acid always retains a
portion of uncombined silicic acid in solution, which deposits
after the lapse of some months in minute crystals of artificial
quartz. It thus appears that water is the solvent of the silica,
which, when recently produced or separated from its combina-
tions by the action of the atmosphere on the earthy silicates,
is presented in the modification most favourable for solution.
The conclusions to be drawn from these experiments simplify
very much our ideas of the silicification of wood shells and
other organic bodies. Geologists hitherto have sought the
explanation of the phenomena of petrifaction in the action of
intense heat aided by pressure. It is clear, however, from
the facts adduced by Dr Bowerbank, that such agencies could
not have obtained during the silicification of his Alcyonium ;
and further, it appears from the preservation of the most
minute tissues in fossil woods, that pressure and extreme heat
could not have been present.
With regard to the preservation of the minute tissues in
various fossil woods, especially the pines and araucarians, as
shown in their radial sections, I had always found a difficulty
VOL, II. 2D
206 Proceedings of the Royal Physical Society,
in accounting for their preservation on any hypothesis, until
an accidental phenomenon enabled me satisfactorily to account
for it.
While preparing chloride of gold, I had occasion to expose
to the action of nitro-muriatic acid many small articles of
jewellery which had been chased and variously-fashioned.
After exposing them for many hours in the usual bath at the
proper temperature, I was astonished to find that none of the
articles had changed either in shape or size, although the
solution showed the proper quantity of gold had been dis-
solved. After decanting the acid, and washing well the
jewellery with distilled water, and again adding a fresh quan-
tity of aqua regia, I found that no further portions of gold
were dissolved, but that the articles still retained their form
and size. Some of the rings, which were chased in high re-
lief, exhibited, as when put into the flask, every mark of the
workman’s tool. The mystery was soon unriddled; the jewellery
had all been alloyed largely with silver, every atom of which
had been changed into a chloride, and as each atom of gold
was dissolved, it was replaced by an atom of the worn silver,
and so the form of each article was retained as when first put
into the flask. On analysis, it was found that no particle of
gold was left—all was converted into chloride of silver. This
fortunate experiment at once enabled me to perceive, that when
a ligneous atom was removed from a fossilising tree, an atom
of silica was deposited, and hence the perfection with which
the most minute structure was preserved.
This being the last meeting of the Session, the Society
adjourned to the commencement of next Winter Session.

APPENDIX
Description of the Bones found in a “ Pict’s House” in the
Island of Harris. Being Notes to Communication read
22d February 1860. By James M‘Bain, M.D., B.N.
The first fragment is a portion of the right side of the upper
jaw of a dog of tolerably large size, with a part of the molar
bone attached ; the sectorial tooth and first tuberculated per-
manent molar remain in situ; and there are sockets for the
second and third premolars in front, with a socket for the last
true molar behind. The sectorial tooth in the upper jaw of
the Canidee is preceded by a deciduous tooth, and is therefore
a premolar. The foramena present in this fragment are the
inferior orbital foramen, the lachrymal canal, the spheno-
palatine foramen for transmitting nerves and vessels to the
nasal fossz, and a slightly developed palato-maxillary canal.
The next specimen also belongs to the dog, and 1s a part of
the left lower jaw; it corresponds in size with the portion of
the upper jaw just described, and probably belonged to the
same individual—it contains the last premolar, the sectorial
tooth, the second true molar, and a socket for the third and last
permanent molar. The sectorial tooth in the lower jaw is not
preceded by a milk tooth as in the upper Jaw, and is in fact
the first true molar. The dental formula of the Canide

by the Masseter muscle in the lower jaw of the dog does not
extend to the under edge of the bone as it does in the fox,
and would enable the comparative anatomist to distinguish
to which of the species this fragment of the lower jaw belonged.
The third specimen is the left tympanic bulla of the common
seal (Calocephalus vitulinus), broken off at the fissure that
divides the bulla from the mastoid process. The mastoid pro-
cess is very slightly developed in the section of the Phocide

to which the Calocephalus vitulinus belongs, and seems to
form a part of the osseous bulla. The fourth fragment is the
basal portion of a horn of the red deer (Cervus elephas), with
a part of the brow antler cut and fashioned by a sharp instru-
ment. The fifth piece is a branchlet of the same species, cut
and hacked apparently for the purpose of breaking it from
the stem. The sixth fragment is a small bit of bone, evidently
a portion of a lesser branchlet, which is also cut and polished.
The seventh specimen is a portion of the left side of the lower
jaw of the Bos longifrons, and contains the second and third
deciduous molars and first permanent molar. The third de-
ciduous molar has three large vertical columns, each with an
inner and outer acute summit, the inner summits rising higher
than the outer. ‘There are two accessory columns, one on
each side of the outer surface of the large middle column,
extending upwards to the base of its summit, with distinct
concentric layers of crusta petrosa, enamel, and central den-
tine. This three-columned deciduous tooth is known to be
succeeded, between the second and third year, by a permanent
premolar with only two columns. The loose teeth also belong
to Bos longifrons ; the tooth marked No. 8 is the first true
molar on the right side of the upper jaw; No. 9 is the last
permanent molar on the left side; No. 10 is a third deciduous
premolar on the right side; No. 11 is the second deciduous
premolar, also on the right side, and all belonging to the upper
jaw. The larger column in these deciduous premolars is
situated posteriorly, and the smaller in front; which character
serves to point out whether they belong to the right or left
side of the jaw. The next two specimens likewise belong to
Bos longifrons ; No. 12 is a cancellous horn core; and No. 13
is the distal portion of the right humerus. The species to
which the name of Bos longifrons has been applied by Pro-
fessor Owen is considered to be the original stock from which
the present domesticated breed of small Highland cattle are
derived. The fourteenth specimen is a portion of the right
lower jaw of a small sheep, containing the two last premolars
and first true molar, with sockets for the first premolar and
for the incisors. The external opening of the inferior maxil-
lary canal is situated nearly midway between the anterior

extremity and the first premolar socket. There is a slight
metallic crust on the inner surface of the teeth, very distinct
on the third tri-columnar premolar. The remaining fragment
in this collection, No. 15, is the upper half or nearly two-
thirds of the right middle metacarpal or cannon bone of a
small-sized horse, from which the upper articulating surface
is separated; the canal for the medullary vessels is recurrent,
and placed close to the outer edge of the groove for the inter-
nal splint bone. The fore cannon bone in the horse is more
flattened in an antero-posterior direction than it is in the
hinder extremity, as in the latter it is somewhat compressed
at the sides, and more rounded.

dress :-—
GENTLEMEN,—I have to congratulate the Society this
evening on again assembling to commence another session,
and with the prospect of having this session filled up with
a series of as interesting and instructive communications as
characterised the one that is past.
On this occasion the congratulations to the meeting would
be unalloyed, were it not that we have to deplore the loss of
one of our office-bearers, whose punctual presence here, not

only on the opening nights, but on all occasions, was always
to be depended upon, and ever hailed with pleasure and confi-
dence. Iam sure it must be the universal feeling of the
members, that in the decease of Mr William Oliphant,
the treasurer, the Society bas sustained a loss which will be
deeply felt, and which cannot readily be replaced, while
every individual has to mourn the loss of a personal friend.
Carefully and liberally educated, and at first intended for one
of the learned professions, the naturally delicate state of
Mr Oliphant’s constitution prevented him from prosecuting
his original intention; but he still chose a walk of life
which gave scope to his love of and desire for knowledge,
and as a publisher he became the successful diffuser, as well
as in several instances the patron and kind friend, of those
engaged in the pursuit of literature and science. Mr Oh- _
phant became a member of the Royal Physical Society in
August 1828, and was thus in connection with it for a period
of thirty-two years. A few years after his entrance, he was
requested to undertake the duties of occasional secretary,
and from 1844 to 1848 he acted as secretary. For the last
ten years, as you all know, he fulfilled the duties of trea-
surer. Under all the phases which this Society has passed
through, from the period mentioned,—1in its prosperity, in its
difficulties, in its temporary decline, and again in its com-
plete revival,—Mr Oliphant tenderly nursed it, husbanded its
funds, preserved its library, and found for the Society this
local habitation, when it removed from its apartments within
the University ; and all this was accomplished in that quiet,
unostentatious, unobtrusive way, which was so character-
istic of his nature. His voice was never heard amongst us
but in the gentlest and most appropriate suggestions—he
never obtruded but to conciliate, to oblige, and to guide by
his advice, which was always sound and considerate. Not
only this Society, but society at large, must feel the loss of
such a man; for it is not those who make most noise, and
take the most conspicuous parts in society, who are in reality
the main stay, and strength, and ornaments of social life,
but such a genuine, highly-principled, unassuming, yet
active, benevolent, and altogether estimable character as

Mr Oliphant. You are all aware, too, what an interest Mr
Oliphant took in our scientific pursuits, and that it was
through him, in the first instance, that an introduction was
obtained to the Calabar missionaries, whose contributions
to the zoology of Western Africa have afforded so many
interesting communications.
During the recess, another and venerable member of our
Society has also paid the debt of nature,—Mr Alexander
Rose, long a well-known lecturer on geology and mineralogy
in this city, who, as often as the growing infirmities of a
good old age would permit, was always a welcome and re-
spected member among us. Mr Rose, a native of Dingwall,
Ross-shire, not far removed from the birth-place of another
of our late lamented and celebrated associates, Mr Hugh
Miller, was also, like him, a self-taught geologist and man
of science—if it may not be said that every man of science
is, in a great measure, self-taught. Mr Rose in early life
became a citizen of Edinburgh ; and, after some years, re-
linquishing an art in which he was both expert and inge-
nious,* he resolved to follow the irresistible bent of his taste
and inclinations, and in time became a celebrated practical
mineralogist and geologist, He, too, was characterised by
his unassuming and genial disposition; and there are not a
few of his attached friends and former pupils who can bear
testimony to his suavity of manners, and the readiness and
ability with which he was ever glad to communicate his
stores of knowledge.
Mr Rhind then referred to the beautiful Ordnance maps
of the county of Edinburgh now before the Society, and
observed that it was no small pleasure to find every inch of
ground which several of us have gone over again and again,
~so accurately and so artistically displayed in one compre-
hensive view before us. To those who many years ago
began their studies in the only field where real knowledge
can be obtained,—in the open field of nature,—such maps
would have been invaluable. What labour, and doubts, and

ployed by the late Sir John Leslie in the construction of his many meteoro-
logical instruments.

mistakes would they not have anticipated ! and yet, perhaps,
the pleasure of working one’s own way, and gleaning infor-
mation painfully and almost in the dark, afforded more real
enjoyment than even to get information thus ready pre-
pared and perfected. The whole district of Edinburghshire
is exclusively a coal-field, forming a portion of that great
Paleeozoic deposit which occupies the basins of the Firths of
Forth and Clyde, extending from sea to sea on the east and
west. A sketch of the filling up of this great basin or open
sea, from the commencement of the Carboniferous era to its
close, and the elevation of the whole by the intrusion of
trap-rocks, was then given,—the total absence of all appear-
ances of subsequent formations, from the Coal to the Ter-
tiaries inclusive, in this district,—then the numerous traces
of the glacial operations visible in the drift,—the evidences
of a greater extension of the present estuary of the Forth
at the close of this glacial period,—and the movements and
changes of level, which probably had a considerable effect
in moulding the present aspect of the district posterior to
the glacial deposits. The earliest notices of the working of
coal in this district, and probably in Britain, occur in char-
ters obtained by the monks of Newhbattle to dig coals on
the Pinkie Burn, near Tranent, in the years 1200 and 1284.
But it was several centuries after this before coal came into
general use. We read of frequent fires occurring in HKdin-
burgh from the ignition of stacks of heather, furze, and
peat, which it was the practice of the citizens to collect and
carefully pile up in the areas and closes for fuel. And so
late as the year 1560, robberies were so common on the
streets in the dark winter nights, that a rope was tied across
the principal thoroughfares, to which a bowat or lantern
was suspended in the centre, containing a single tallow
candle, which “ paled its ineffectual fire,” where now, in the
same localities, gas blazes, and innumerable coal fires enliven
the gloom of the winter nights. It is well known that
Newcastle coal was prohibited to be used within the city of
London by act of Parliament, on account of its “‘ noxious,
sulphureous, and pestilent smoke ;” while at the present
day no less than seventy millions of tons of coals are raised

in Britain. A small portion of this is exported, but the
great bulk is used for domestic purposes and manufactures,
—for animating the giant arm of the steam-engine, and for
sending our steam-ships over every region of the globe.
The present aspect of the county was next alluded to,—its
division into three alluvial valleys, watered by three rivers
which flow into the estuary of the Firth,—the Pentland
range of hills, their diversified scenery,—and the remarkable
basaltic rocks surrounding and forming the basis on which
the city is built. There are no means of knowing what was
the condition of the local atmosphere of Mid-Lothian in
former times—at periods when the country was more densely
covered with wood, when the ancient forests of Scotland
still remained, when the surface of the soil was only par-
tially cleared and cultivated, and imperfectly drained, and
when marshes and lochs were greatly more abundant than
they are at present. In the absence of actual facts, people
are apt to draw on their imaginations and feelings; and
it depends a good deal on the individual temperament
whether we hear that the seasons are become much more
severe and ungenial, or warmer and drier, than they were in
bygone days. It was only towards the end of last century
that scientific instruments were employed to indicate the
climate of the country. From those begun by Professor
Playfair in 1771, and others, continued down to the present
day, it appears pretty evident that no change of climate has
taken place during the last ninety years. Considerable
varieties of seasons occur ; the general or normal was pointed
out, and the occasional or abnormal, with their distinctive
peculiarities, and the great leading or general causes of dif-
ference, traced to the predominating power of the south-
west and north-east air currents,—the predominance of one
or the other forming the main cause of the varieties of sea-
sons,—and to the influence of the great Gulf Stream, which
flows past the British Isles. Local ameliorations of climate
by drainage, cultivation of the soil, protection of plantings,
&e., while they are of the greatest importance to the agri-
culturist and in a sanitary point of view, would appear to
be too small to affect the general climatal averages. The

mean annual temperature of the lower portion of the county,
embracing a: series of years, may be stated at 47-2 Fabhr. ;
the rain-fall 24:6 inches. The mean annual temperature of
the city of Edinburgh, for the last three years previous to
1860, is 48°:3 Fahr., by the lists of the Meteorological So-
ciety. This is equal to if not higher than the annual tempe-
rature of any of the Scottish towns, and only 2° lower than
London. -The annual rain-fall. at Greenock, on the west
coast, is two-thirds more than that of Mid-Lothian. Mr
Rhind concluded by recommending to the members of the
Society, of whom there were several eminent in the various
departments of natural history, to combine their labours in
a complete investigation of the physical history of the
county. . We owe much, he said, to the labours of our pre-
decessors in this respect ; and itis but just that we should
endeavour to do something for those who are to succeed us.
A vote of thanks was unanimously given to Mr Rhind
for his address, and his valuable services while President
of the Society, his term of service having now drawn toa
close. .
The Secretary was instructed to engross in the minutes of
the meeting portions of the President’s address referring to
the death of Mr William Oliphant; and to send an extract
of the minute to his widow, Mrs Oliphant, as a mark of the
Society’s respect for the memory of. its late member and
office-bearer, and of sympathy with her in her bereavement.
The following communications were then read :—
I. Observations on British Zoophytes and Protozoa.
(1.) Notice of Ophryodendron abietina (Corethria sertulariz). (2.) On the
Reproductive System of Chrysaora. By T. Strernitn Wrieut, M.D.
(1.) On Ophryodendron abietina.—Amongst the lower
classes of animals, and especially in the Protozoa, the lowest
class, numerous and very striking examples of homomor-
phism occur. ‘ Homomorphism” is an exact simi-
larity in form between animals of different classes, without
any corresponding resemblance in their anatomical struc-
ture. Some of these examples may be considered fanciful,
as the likeness between Lacrymaria olor and the fossil
Observations on British Zoophytes. 217°
reptile Plesiosaurus. But in others the homomorphism is
so perfect, that animals belonging to the lower class were
long confounded by the most eminent zoologists with those:
_of a higher class. Thus, various species of the Fora-
menifera were classed amongst the Cephalopoda. The
shells of many of the Foramensfera are, indeed, exact
copies of those of Cephalopoda, both recent and fossil.
The recent Nautilus and Argonaut, and the fossil Bacu-
lite, Orthoceratite, Hamite, and Ammonite, find their
representatives in the microscopic Nwmulina, Polystomelia,
Dentalia, Cristellaria, and Rotalina. The shells of the for-
mer are inhabited by the highly organised cuttle-fishes ;
those of the latter by creatures which can scarcely be said
to possess any organization. The chambers of their shells
are filled with a glairy living mass, which streams like a
fluid in and out through the innumerable minute pores with
which the shells are pierced. The streams unite together
to form widely-spread meshes and expansions, which en-
velope, absorb, and digest smaller living beings coming in
contact with them, and on which the animals move, or
rather flow along. But although the forameniferous ani-
mal is a mere fluid mass, destitute not only of organs and
stomach, but even of the simplest cellular structure, it is
yet capable of exercising the most important functions of
life—motion, nutrition, and reproduction,—and of erecting
for itself edifices mathematically correct in design, which
arrest the eye by their exceeding beauty of form and orna-
mentation, and which, deserted by their tenants through
successive ages, have formed no inconsiderable part of the
solid frame-work of our globe. fucicola

It will thus be seen that there is a very gradual transition
from the alimentary polyp to the reproductive polyp, and
from the latter to the simple generative sac. Professor All-
man’s term “ blastostyle,” applied to the reproductive polyp,
is apt to mislead, as it indicates that the alimentary and re-
productive polyps are not homologous parts. Still more
decidedly does that accomplished naturalist confuse the
homology of these parts by applying the same term to the
branched pedicle of the aggregated generative sacs of Tubu-
laria tndivisa, which is merely formed of the conjoined and
elongated pedicles of the individual sacs.
It is impossible to construct any classification of the Hy-
droid Zoophytes on the form or position of their generative
sacs or medusoids, as these vary not only in different species
of the same genus, but also in males and females of the
game species. Thus, in Hudendriwm rameum the sperm-sacs
are moniliform, the egg-sacs single ; the former are attached
to the alimentary polyp, the latter to the polyp and also to
the polypary. In Hydractinia, although the generative sacs
generally spring from the reproductive polyps, they are also
found attached to the polypary; and in a most interesting
species of this genus lately discovered by Mr Alder, medu-
soids spring from the latter part of the zoophyte. In Atrac-
tylis ramosa, T.S8.W. (Eudendrium ramosum, Van. Ben.), the
medusoids, the males and females of which differ in shape,
spring from the polyps, from club-shaped bodies, and from

the polypary ; in other species of Atractylis they arise from
the reticulated base of the zoophyte. In certain species of
the genera Sertularia and Campanularia, marsupial forms
occur which bear no homological relation to each other.
The gradual transition in the Hydroide from the simple
generative sac to the perfect Medusa is exceedingly interest-
ing. I attempt to indicate it in the following sketch :—

Of the generation of Stomobrachiwm we know nothing.
Claparéde has shown that gymnophthalmatous Medusee may
produce Medusee without the intervention of the polypoid
phase ; but it is impossible to draw any line of distinction
between a Medusa and the medusoid phase of the Hydroid
polyp. Zubularia indivisa produces its young as perfect
polyps without the intervention of the planuloid phase, Clava
with the intervention of that phase. In the life-history of
Appendix to Cionistes reticularis. 281
the Hydroide, any phase—planuloid, polypoid, or medusoid
—may be absent.
The perfect several-lipped Medusa appears to be a sym-
metrical organism composed of eight or more elements, each
element corresponding to the half of a lip. Hach of these
elements is composed of three subelements, the alimentary,
reproductive, and prehensile, any of which may be sup-
pressed, or unite with others of different value on the same
element, or of the same value belonging to neighbouring
elements. Thus, in Sarsia the peduncle appears to consist
of a single alimentary subelement, and the single reproduc-
tive element or generative sac extends around and along the
whole of it except the single trumpet-shaped lip. This lip
is occasionally placed on one side and at some distance from
the extremity of the peduncle, indicating the asymmetrical
character of the latter organ in this genus. In Huphysa and
Hleutheria the ovisacs coalesce, and are placed within and at
the base of the peduncle. Steenstrupia and Saphenia furnish
examples of the suppression of certain of the marginal ten-
tacles or prehensile subelements, and the exaggeration of
others.
The Polyp of the Hydroid Zoophyte must also be con-
sidered as composed of one or more elemental zooids. Thus
we have the zooid of asingle element in the ‘tentacular polyp’
of Hydractuma ; the zooid of two elements in the two-ten-
tacled and two-lipped Lar Sabellarum (Gosse) (Pl. XII. fig.
8), and in the minute two-lipped and non-tentacled polyp
which occurs on the Antennularias and others; the zooid of
several elements in the five-lipped polyp of Trichydra
(T. 8. W.); that of many elements in the polyp of Tubula-
ria indivisa, which I have elsewhere shown to be formed by
the confluence of the several distinct tubes of which the po-
lypary or coenosarc is composed, each of which tubes may be
traced, by its coloured endodermal ridges, to the mouth of
the polyp, and bears its own system of tentacles and repro-
ductive apparatus.
_ The compound character of the polypary is also seen in
Halecium and Antennularia, and in a very beautiful manner
in the very early state of Sertularia pumila, which (after it
282 Proceedings of the Royal Physical Society.
had been kept a few days in fresh water) I have figured with
the camera in Pl. XII. fig. 12. Its resemblance to Carus’s
figure of the Medusa, Cunina globosa (Esch.), which I have
copied in fig. 11, is very striking.
As the Medusa is a multiplex organism, we must inquire
how far it is homologous with the generative sac of the Hy-
droid Zoophyte.
Prof. Allman, in his paper on Cordylophora (Phil. Trans.
vol. cxli.), advanced the doctrine that the generative sac
was homologous with the whole Medusa—a doctrine based
upon an erroneous conception of the cavity in which the
generative elements arecontained. Ina ‘Note on Dicecious
Reproduction in Zoophytes” (Edin. New Phil. Jour., vol. iv.
p- 88), I stated that “the reproductive buds [generative
sacs] (of Coryne) were filled with ova developed from the
exterior of a hollow central stalk, a diverticulum of the
alimentary canal;” and further, ‘‘ The peduncle of the
Medusa-bud [or budded Medusa] appears to me to be homo-
logous with the entire reproductive capsule [generative sac]
of Coryne glandulosa, &c.” This view is now adopted by
Prof. Allman, who writes, in ‘ Annals of Natural History,”
(vol. vi. ser. 3, p. 4), “‘ The manubrium is the whole of the
‘peduncle,’ ‘stomach,’ or by whatever other name it may be
called, which depends from the centre of the umbrella in a
Medusa or medusoid ; and I apply the same term to what
I consider the homologous part in a sporosac, namely, the
whole sporosac minus the ectotheca and mesotheca.” Now,
the ‘ sporosac,’ less the ‘ ectotheca’ and ‘mesotheca,’ is the
simple generative sac, which, therefore, Prof. Allman has
agreed with me in considering homologous with the peduncle.
But I would now very much modify the above view. We
must keep in mind that each of the eight elements of a
medusoid has three distinct functional subelements; that
the single reproductive subelement of the Medusa exists,
as in Stomobrachium, uncombined ; that where the peduncle
is the reproductive organ of a free Medusa, as in Sarsza, it
_ consists of two subelements of different function combined,
each exercising its separate function, alimentative or repro-
ductive; that an organ composed of a single subelement (a —
Appendix to Hydractinia. 283
generative one) having only one function, cannot be homo-
logous with one composed of two subelements (peduncle of
Sarsia), each having its distinct function, or with an organ
of sixteen subelements (peduncle of Bougainvillea), eight
of which are alimentary and eight reproductive. I would
therefore now state—
That the simple generative sac of Coryne is homologous
with the reproductive subelement or single generative sac
as it exists on the lateral canal of Stomobrachium.
That the peduncle-like sac of Hudendrium confertum 1s
homologous with the reproductive subelement in the pe-
duncle of Sarsta—not with the whole peduncle.
That where the generative sac evidently consists of many
subelements, as in Tubularia larynx and Sertularia fallax
(evidenced by the four summit-lips or lobes, the symmetri-
cal character of each of which indicates it to be composed of
two subelements), it is homologous with the reproductive
subelements in the octopartite peduncle of Bougainvillea,
or, rather, with the eight coalescing reproductive subele-
ments of Hleutheria.
I consider that a four-lobed or branched state of the pla-
centa or spadix indicates a multipartite constitution of the
generative sac, and not a rudimentary medusoid form of that
organ; for we have, in the fixed female medusoid of Lao-
medea Lovent, a four-lobed condition of the placenta in the
peduncle-like ovisac, with the existence of a well-differen-
tiated subumbrella and lateral and circular canals.
My space will not allow me to illustrate the homological
relations which exist between the polypary (or ccenosarc)
and the polypidom on the one hand, and the subumbrella
and umbrella on the other. This must be reserved for a
future occasion, when I hope to fill up the gaps in this
rough and incomplete sketch of some of the morphological
relations of the Hydroide and their Meduse.
Appendix to Hydractinia, printed at vol. i. p. 192.
In the “ Annals of Natural History ” (vol. iv. ser. 3. p. 50)
| Prof. Ailman has remarked, with regard to Hydractinia,
that “the solid chitinous polypary [polypidom] is covered

externally by the ccenosare [polypary], thus reminding us
of the sclerobasic corallum of some of the Actinozoa.” This
doctrine had been previously promulgated by Quatrefages
(Ann. des Sc. Nat., xx. 232), who considered the polypidom
to be an endoskeleton deposited in the substance of the
polypary, like the solid axis of Gorgonia. If this view were
correct, it would not only remove Hydractinia from the
Tubulariade, but would segregate it from the whole of the
Hydroid Zoophytes, not one of which is destitute of an
investing polypidom.
~ In the “ Edinb. Phil. Journal” for April 1857, I stated, in
a paper on Hydractinia, my conviction of the incorrectness
of Quatrefages’s opinion, and that the mode of secretion of
the polypidom of Hydractinia did not. differ from that of
the rest of the Tubulariade, as was seen in the development
of its young and its propagation by stolons. Since then I
have come to the following conclusions, after the examina-
tion of a very large number of specimens, some hatched
from the egg and adherent to glass, others removed as cut-
tings from adult specimens and transplanted on glass, to
which they readily grow, and others removed entire from the
shell of the Pagurus by acid, and put up in spirit or balsam.
The polypidom and polypary are found in the following
forms, all of which are frequently combined in the same
specimen :—
1. An open network of delicate chitinous tubes without
spines, enclosing a polypary composed of several combined
endodermal tubes surrounded by a single layer of ectoderm.
Found in very young specimens, or in old ones growing on
protected parts of the shell. (Analogous to Clava repens
(mihi), the C. discreta of Allman.)
2. An open network as in the last; the tubes of thick
brown chitine, with single hollow spines rising from a single
tube, or from the confluence of four tubes.
3. A close reticulate plate, as in Clava cornea (mihi) and
CO. membranacea (rihi), formed from states 1 or 2 by the
continual filling-up of the meshes by anastomosing branches,
with or without spines.
4, A fleshy plate of ectoderm permeated by a network of
Appendix to Hydractinia. 285
endodermal tubes, and covered above and below by a deli-
cate investment of chitine. Found on the growing borders
of the zoophyte, and especially in cuttings of old specimens
transferred to glass.
The spines are composed of one tube or many parallel
tubes: they may be single (PI. XII. fig. 4), and developed
on a single tube of the polypidom, like those of Podocoryne
Jucicola; single at their summits and of several tubes at
their base (figs. 5 and 6) ; composed entirely of several (8-12)
conjoined tubes (fig. 7); reticulate by the lateral anasto-
mosis of their tubes; or consisting of long ridges of tubes
reared against each other.
The polyps spring from one or several confluent tubes of
the polypary ; they are covered at their origin, and for a little
distance above it, by a delicate prolongation of the poly-
pidom. This may be detected by dyeing the whole zoophyte
with tincture of kino, which gives different tints to its
chitinous and fleshy elements, or by steeping it alternately
in spirit and water, when the coverings of the polyps and
polypary become inflated as in figs. 2 and 3.
The polyps are of several shapes and functions, which I
have described in the paper cited above. It will be sufficient
to enumerate them here :—
1. Alimentary polyps, with mouth and tentacles.
2. Reproductive polyps, with rudimentary mouth and
tentacles.
3. Spiral polyps—a modification of the last; generally
barren (fig. 3).
: Sessile generative sacs of thes polypary.
. Tentacular polyps, or great tentacles of the polypary
om 2).
In the reproductive organs of Hydractinia there is a
gradual transition from the reproductive polyp to the sessile
generative sac; the polyp loses its dot-like mouth, its ten-
tacles, its head or upper part, and finally dwindles down to
a mere sperm-sac. This change is generally seen in those
specimens which have long been kept in captivity. In these
specimens, too, many of the alimentary polyps are often
converted into large inflated sacs destitute of mouth and

tentacles, and showing through their parietes white longi-
tudinal ridges, which indicate the number of zooid elements
of which they are composed.
In the natural history of this remarkable zoophyte there
are other points of peculiar interest, which, having already
described, I need only mention here: the slow development
and unique shape of the planuloid larva; the powerful
muscular structure of the polyps, especially the spiral ones,
the office of which last has yet to be discovered; and the
intimate sympathy and combined action which subsist be-
tween the various parts of the whole animal.
III. Notes on Deep Sea Soundings. By E. W. Dusuc,* M.D., R.N.
: Communicated by Mr James B. Davis.
The deposits now forming at the bottom of the ocean
possess a peculiar interest from a zoological as well as from
a geological point of view, especially when we consider the
importance of the natural processes upon which they are
capable of throwing light.
It is only of late years, however, that we have been en-
abled with any degree of accuracy to sound the vast depths
of the ocean, to map out the varying configuration of the
solid substrata, and to examine into the nature of the latter.
We owe this in great measure to the invention of an im-
proved form of sounding apparatus by Mr Brooke of the
United States Navy.
Specimens thus obtained from great depths were sent to
Professor Ehrenberg of Berlin, and Professor Bailey of New
York. The latter submitted samples of the sea bottom from
that part of the North Atlantic which covers the telegraph
plateau to microscopical examination, and found them to be
filled with minute organisms, and to contain neither sand
nor gravel. The organisms were mainly calcareous, consist-
ing of the shells of various genera of Moraminifera (Poly-
thalamia of Ehrenberg). ‘There were besides a small number
of the siliceous shields of diatoms.
* T observe, with much regret, a notice of the death of Dr Dubuc on board
H.M.S. Cossack, at the Cape of Good Hope, on the 10th of January 1862, at
the early age of 24.—J. B. D.
Notes on Deep Sea Soundings. 280
Owen mentions polycistine as also occurring in speci-
mens from the bottom of the North Atlantic.
Through the kindness of T. C. Scott, Hsq., R.N., I am en-
abled to lay before you various samples, likewise, from the
telegraph plateau, the result of soundings made in H.M.S.
Bulldog. They are of a light yellow colour, and effervesce
strongly with acid.
In the microscopical slides before you, you will readily
perceive numbers of calcareous foraminifers of genera re-
sembling Rotalia and others; besides there are here and
there, but usually in fragments, the beautiful tessellated
siliceous shields of coscinodiscus.
It is a curious circumstance, that, in many instances the
polythalamie were brought up from the same locality with
the soft parts still preserved. Lieutenant Maury conjectures
that perhaps the bodies of persons buried in the deep
sea may in like manner be preserved for long periods, the
great pressure to which they are subjected preventing de-
composition, by opposing an ‘obstacle to the separation of
gaseous bodies.
Prior to the laying down of the submarine cable between
Kurrachee in Scinde and Muscat in Arabia, a number of
soundings were made along the proposed route by Captain
Pullen in the Cyclops. I obtained two specimens which
were brought up, one from a depth of about 200, the other
from about 700 fathoms, off the south coast of Beloochistan.
The sea is very deep in this locality, especially towards the
sea of Oman which parts Beloochistan from Arabia. While
the temperature of the air where these soundings were being
taken was almost tropical in character, the thermometer
attached to the sounding apparatus showed that the tem-
perature at the bottom of the ocean was under 40° Fahr.
The matter collected at 200 fathoms resembles bluish
clay. It does not effervesce with acid, and under the micro-
scope it presents toview a number of clear angular fragments,
many of them undoubtedly of mineral origin.
The calcareous foraminifers so plentiful in the deposits
from the North Atlantic are here very rare. After diligent
search I could only recognise two or three. Here and there
268 Proceedings of the Royal Physical Society.
we meet with spicule of sponges. There are also present
the broken, and, in some cases, perfect valves of the coscino-
discus, but any other organisms are too undecided to pro-
nounce upon.
The sample from 700 fathoms is still less aivundanied in such
objects.
Deep sea soundings have now been effected in various
parts of the world. Professor Bailey examined specimens
brought up in Lat. 56° 46’ N., Long. 168° 18’ E., the depths
being respectively 900, 1700, and 2700 fathoms.
They yielded a variable proportion of mineral matter,
diminishing as the depth increased, a quantity of the silice-
ous shields of diatoms including coscinodiscus and numerous
spicule, but not a fragment of any of the calcareous poly-
thalamia. The beautiful siliceous polycistine were also
observed.
A specimen brought up by Brook’s sounding-rod in the
coral sea, in Lat. 13° 8., Long. 162° E., from the reported
depth of 2150 fathoms, afforded many spicule of sponges, a
very few diatoms including the coscinodiscus, some. polycis-
tine, and a very few fragments and only one perfect poly-
thalamia shell.
The deposits now forming at the bottom of the North
Atlantic, therefore, differ notably from the latter, in contain-
ing so many polythalamie.
Perhaps at some future date we may be able to discover
some connection between the various minute forms and the
localities at which they occur, as well as the currents flowing
in the waters below which they are met with. At present
we must content ourselves with accumulating observations.
IV. Further Notice of the Herring and Sprat Fishery of the Firth of
Forth. By Groner Loaan, Esq., Convener of the Society’s Committee
on Marine Zoology.
In continuation of the remarks upon the herring and
sprat fishery of the Firth of Forth, submitted to the Society
in the Report of their Committee on Marine Zoology, on
24th January last, the Convener pursued a careful exami-
nation of the fish brought to market daily, through the
The Herring and Sprat Fishery of the Firth of Forth. 289
months of February and March, and he found that any
appearance of herring fry gradually ceased, while the sprat,
Clupea sprattus, was most abundant; even the occurrence
of young herrings, 7.e., fish above five inches long, was rare,
until about the beginning of March, when for a day or two
they again made their appearance among the sprats in some
numbers, and then entirely disappeared. About the 10th
of March considerable quantities of very fine pilchards,
Clupea pilchardus, the gipsy herring, were brought to market,
along with herrings and sprats, and the writer of this notice
examined seme dozens of them. ‘The largest were fully
eight inches in length, and might readily be mistaken for
herrings, although upon a closer inspection the general
aspect of the fish showed marked distinctions even to the
eye,—being more slim and delicate, having smaller scales,
more firmly attached, and, when compared side by side
with the herring, giving one the impression that it might
be a young herring which had only just attained maturity.
The marked distinctions between this fish and the herring
need not be repeated ; Dr Parnell states them most accu-
rately, and says that it had been of late (when he wrote in
1839) a very rare fish in the Firth of Forth, as well as along
the whole eastern coast of Scotland; while, about thirty
years previous, it had been as plentiful as the common
herring ; and that no specimen had then been caught in
the Firth since the year 1816. He adds that the pilchard
is easily distinguished from the herring, sprat, and white-
bait, by the position of the dorsal fin. If either of the
three latter fish be suspended by the anterior dorsal rays,
the head will be observed to dip considerably ; whereas, if
the pilchard be thus suspended, the body will preserve an
equilibrium. ‘The writer found that the fishwomen thor-
oughly apprehended this last-mentioned characteristic of
the pilchard as the one most obvious and unmistakeable
by an observer, and were quite aware of the nature of the
fish they were bringing to market as distinguished from
the herring, stating, that by many people they were not so
much liked as food. Many of the specimens were opened
by the writer, for the purpose of ascertaining the existence
290 . Proceedings of the Royal Physical Society.
of milt and roe, but not the slightest appearance of the
latter could be found, the milt being, however, distinctly
seen in a rudimentary state. These fish, when dressed for
table, were found to be in very fine condition, although
differing in flavour from the herring, and to some tastes, as
the fishwomen had said, not so palatable. It was matter
of regret that the pilchards were only caught in large
quantity for a few days in March, although sparingly
among herring through the winter; and this partial appear-
ance in the Firth in the present season corroborates Yar-
rell’s statements on the subject. As respects the spawning
of the herring, the best authorities hitherto, although with
some doubt and misgiving, have assigned the periods of
March and October as the times of deposit. The writer has,
during the past winter, found the herrings taken in the
Firth of Forth to be either gravid with spawn and milt, or
else spent fish, continuously from the month of November
until the end of March, during the whole period that the
fish was sought after and taken; and he sees no reason to
doubt that during the whole period that the herring is
found upon our shores, it is there for the purpose of depo-
siting its spawn, which not improbably occurs the whole
year round.
Mr J. M. Mitchell exhibited several specimens of the sprat
or garvie herring, Clupea sprattus, with well developed milt
and roe. These fish were taken above Queensferry about
the end of March.
V. Notice of a Specimen of the Syngnathus Aiquoreus, taken in a lobster-
net off Inchkeith, 17th April 1861. By Witiiam S. Youne, Esq.
Specific Characters.—P. ©. and A. fins wanting; dorsal
and vent nearly in middle of entire length, resting on eleven
rings, three of which belong to the tail.
Description of this specimen: 21 inches in length; head —
jsth of whole length. From point of snout to the orbit,
1 inch; from orbit to extremity of operculum, ?th inch;
from end of snout to first dorsal ray, 83 inches; from last
Notice of the Syngnathus AXquoreus. 291
dorsal ray to extremity of tail, 103th inches ; length of dorsal
fin, 2? inches, with 39 rays resting on eleven rings, three of
which belong to the tail.
The trunk consists of 29 divisions or rings, and the tail of
about 60 or 64; vent immediately under the twenty-seventh
ray of the dorsal fin.
Form of the trunk from the gill to the vent is octangular,
and from the vent downwards quadrangular, towards the
extremity somewhat flattened.
I have given this description, as it differs somewhat from
most of the descriptions of this fish. Jenyns and Yarrell
give it rudimentary caudal rays, and Kaup six caudal rays.
In this specimen I could not discover, even with the micro-
scope, the faintest trace of a rudimentary ray, when not
more than half an hour dead. Kaup says that this species
has till now (1856) been found only in the south-west
coast of Scotland, in Ireland, the Isle of Man, at Havre, and
in Norway. He does not appear to be aware, as noticed by
Dr Parnell, that prior to 1685 Sir Robert Sibbald obtained
a specimen from the Firth of Forth; and within the last
few years, Dr J. M‘Bain and Dr J. A. Smith each got speci-
mens. The last is now in the Natural History Museum,
College, Edinburgh.
[As this fish has not been often distinguished or de-
scribed, there are here added, for the sake of comparison,
the notes formerly taken from the specimen examined by
Dr Smith, and exhibited at the meeting of this Society, on
25th January 1860. These details were not included in the
notice of the fish printed in the Proceedings, see page 139.

Length, 20 inches full; 94th inches to vent from point
of snout; and 10%ths inches from vent to point of tail.
Length of head, 18thsinch. From snout to front of orbit,
3ths of an inch full; from thence to extremity of gill-cover
(including the eye), 2ths of.an inch. Length from point
of snout to commencement of dorsal fin, 7ths inches (the
fin is 24 inches in length); and length from beginning of
fin to extremity of tail 123ths inches. The termination of
the fin is therefore nearly the middle point in the length
of the body—the fin being in front of the middle of the
fish. 4
The body, or portion of fish from head to vent, consists of
30 plates, rings, or divisions (the vent being situated in the
thirtieth plate or division, and under the twenty-sixth ray
of dorsal fin); and there are 64 or 65* plates or divisions
from vent to end of tail; the transverse markings cease
beyond vent. Dorsal fin has 39 fin rays, on eleven rings,
and a very slight attachment to another in front, three of
which rings succeed the anal ring, and therefore belong to
the tail ; the fin commences at the latter part of the twenty-
second transverse plate, and extends past the middle of the
thirty-third plate or ring.
These divisions and transverse plates are distinct, and
the angles of the octangularly-shaped body are also tolerably
distinct ; the dorsal one is not acute, but rather rounded, the ~
first and second lateral being the most distinct; these last,
on each side, form, behind the vent, the distinct angles of
the quadrilateral body, which also decreases considerably in
size, and tapers gradually to the pointed extremity of tail.]

* Yarrell, in the first and second editions of his “ British Fishes,” erro-
neously quotes from Montagu’s original description of this fish (Wern. Mem.,
vol. i. p. 85) the statement, that, from the vent to the extremity of the tail,
this fish consists of ‘‘ about thirty-six plates,’ whereas, in Montagu’sdescrip-
tion, it is stated to be “about sixty-six plates.’ This is probably merely
a typographical error. =a

was in beautiful plumage. Mr Charles Muirhead, Queen
Street, informed Dr Smith that it was shot near Bathgate
on the 17th of March. The bird is rare, or at least seldom
seen in the neighbourhood; and this specimen is also in-
teresting from the very early season of the year when it
was killed. Montagu mentions having seen it in Devonshire
“as early as the 14th of March.” It is generally considered
to be migratory,—one of our regular summer visitors. Its
allied species, the Corn Crake, does not visit us until the
beginning of May.
A vote of thanks was given to the Orricz-BEARERS, and
the Society adjourned to the beginning of next winter
session.

Dr Wrateat then delivered the Opening Address :-—
GENTLEMEN,—I have now to greet you on the commence-
ment of the ninety-first session of the Royal Physical Society,
which opens full of promise. Not only can we look back
with satisfaction on the many valuable papers which have
of late years been read at this table, and which, treasured
up in our published proceedings, and disseminated through
VOL, Il. 2@
296 Proceedings of the Royal Physical Society.
the scientific societies of this and other countries, are assist-
ing to preserve for Edinburgh that high position which she
has attained in science; but the billet of this evening shows
that, in the ensuing session, we have much to look forward
to, both from our young soldiers, whose spurs are yet a-win-
ning, and from well-tried veterans, whose names for many
a year have been ‘‘ familiar as household words” to the lips
and pens of all those whom Natural History has taken for
her own. Moreover, a highly respectable balance in the
bank, and the continued influx of entrance-fees from new
members, render us quite easy as to that commodity with-
out which the highest literary and scientific attainments
present but a pitiable appearance—so very easy, that a large
number of our members, nearly all of us, have neglected for
some years to pay our annual contributions. The Council
have, however, considered it unadvisable that the property
of the Society should any longer be carried about in the
pockets of its members, and have directed that the arrears
shall be collected, so that our available funds this year will
be considerably increased. Since our last meeting, the
Society has been deprived of the services of several useful
and valuable members. One of them—Professor Shank
More—has been removed by the hand of death. Ineed not
in this place recount the history and attainments of one so
well known as Professor More. The increasing infirmities
of age had for some time prevented his taking any part in
the business of the Society, but he never ceased to show an
interest in its welfare. We have suffered a severe loss in
the removal from Edinburgh of two of our most skilful
workers—Mr Andrew Murray and Dr Cleland. To the love
of scientific research, the forcible style, the skilful pencil,
and the unceasing activity of Mr Murray, the first volume
of our Proceedings owes the chief part of its attractions ;
while his kindness of heart, and the ready interest he always
took in the labours of his brethren, will long be remembered ~
by us with regret. I have no hesitation in stating that the
papers which Dr Cleland has communicated to this Society,
and elsewhere, have placed him in the highest ranks of
science as an accomplished comparative anatomist, and we

must hope that we may still be favoured by his assistance,
although he may not often be able to come amongst us.
The work of the Society for the last session has been well
divided amongst the members. On the Vertebrata the
papers consist of those of Dr Cleland on the articular pro-
cesses of the Atlas and Axis; Dr M‘Bain on the anatomical
distinctions between the skull of the Manatus senegalensis
_ and a Manatus from the Bay of Honduras ; Mr Edwards on
inflammation in fishes, in which he has determined that
those animals are quite indifferent to the infliction of wounds;
Mr Peach, of Wick, on the Argentine, Anchovy, and other
fishes, and on the termination of the vertebrate column in
the tails of the Salmon tribe; Mr J. M. Mitchell and Mr G.
Logan on the natural history and fisheries of the Herring
and the Sprat; Mr W. 8. Young on the Ciquorial pipe-
fish and its specific distinctions. In Entomology, Mr R. T.
Logan’s paper—on the occurrence of Vanessa polychlora and
Cheimatobia borearea in Kdinburghshire. On the Celentrata
two notices by Dr Strethill Wright—on reproduction in
Chrysaora, and on Atractylis coccinea. On the Protozoa we
have Dr M‘Bain’s notices of sponges from Shetland and else-
where, together with his very valuable and interesting ex-
position of Bowerbank’s recent discoveries and classification,
and Dr Strethill Wright’s papers on reproduction in Ophryo-
dendron, on Dendrophrya and Lecythia, and on Rhizopod
structure, and his discovery of ova and spermatozoa in that
class of animals. In Geology and Mineralogy several very
important papers have been read, including Mr R. H. Tra-
quair’s on the Trilobites of the Carboniferous Limestones of
Fifeshire, accompanied by beautiful delineations of species.
Mr Andrew Taylor on the exposure of the Liberton Old Red
Sandstone conglomerate bed at Newington; and Mr John
8. Livingston on the state of our knowledge respecting meta-
morphism in the mineral kingdom, in which he has given a
most interesting account of the production of minerals by
artificial means. To all these gentlemen I beg, in the name
of the Society, to give cordial thanks for their assistance in
the furtherance of its objects. To Dr J. A. Smith, our
Secretary, special thanks must be offered for the constant

supply of objects of interest which he has every evening
placed upon our table, and his valuable observations thereon;
and to Mr G. Logan, the Convener of the Dredging Com-
mittee, for his Report.
Such has been the result of the past session. Good
steady work has been done, and patiently recorded. We
are men of work, not of talk. We have given forth no
voice on the grand hypothetical questions which are now
troubling the commonwealth of Natural Science. We have
been singularly apathetic as to whether or no the stock of
our first parent struggled upwards through innumerable
adversities from a monad to a man. I fear, indeed, that we
are prejudiced people, and would rather leave the question
as we found it settled many a year ago at our mother’s side.
We have given no opinion as to whether the king of the
Gorillas died gloriously advancing on his terror-stricken foe,
and beating a far-resounding tattoo on his tympanic chest, or
whether he was brought to the ground by a rifle-shot in his
cerebellum while ignominiously bolting up a tree. But we
have been jotting down hard little facts,—rough diamonds,
which by-and-bye we may see taken up and ground, and
polished, and set by other hands,—central points of crystal-
lization, which we may find dotting the pages of great
standard volumes, and glimmering from amid the small
type of their foot-notes and indices. Sic itur ad astra.
These small facts are the foundations of adamant on which
the vast mverted pyramids of science are balanced. In
their discovery they are providential revelations, which,
though neglected for ages, may in a moment endow man-
kind with unhoped for welfare and prosperity. How often
have men, dreaming of the transmutation of all metals into
gold which would be useless—of the attainment of the
EKlixirwhich would confer a dreadful immortality,—cast aside
the talent placed within their hands, and all that would
have made the life ordained for them useful and happy!
How often, while invoking all nature to furnish us with
the impossible Roc’s egg, have we pushed aside the little —
dusty copper lamp, which, in return for diligent rubbing,
would have invested us with the powers of the genius of

Arabian fable! How little did he, who first noticed the
attractive property of the loadstone, imagine that to him was
revealed a power which would one day guide the commerce
and navies of the world over the pathless seas,—which
would veer off the floating city, laden with the hopes of a
thousand human hearts, and careering over the dark waves
with the speed of the wind, from the treacherous iceberg
and the crashing floe,*—which would link together in the
closest bonds all the kingdoms of the earth,—which could
correlatively transmute all the forces of nature—and which
may one day render the great sea itself one mighty store-
house of fuel and power for the benefit of mankind! How
little did he, who first linked together an atom of hydrogen
with two of carbon and three of chlorine, dream that then
was revealed to mankind the beneficent HKlixir which would
cause that dread and ancient travail of the woman to cease,
—which would change the despairmg moan and the agon-
ising terror of the operating table for a calm and dreamless
slumber—and which shall render the fame of Dumas and
Simpson undying, until the stream of time shall flow for
suffering humanity no more!
So it may happen that some unambitious observation made
here may throw unexpected light on the Geology of our
country,—may endow vast districts with mineral wealth
undreamt of,—may modify all our received views of cell-life
—and may put down a hard little point, on which may arise
the Physiology and Pathology of the future. Let us there-
fore go on as we have done, not urged by the desire of fame or
notoriety, but constrained by the love of knowledge and truth.

Our Society has still another function. It plays its part
as an exponent, through its reports in the daily press, of the
progress of Natural Science—a knowledge of which cannot
fail sooner or later to give a higher tone to the literature and
cast of thought in our country. It is painful to notice how
the writings of many of the most talented and accepted
authors of our day are entirely uninfluenced by the sublime
realities of Creation,—realities which excel in their grandeur
the most transcendent dreams of the imagination. The
poet who prates of ‘‘ the pale cold moon,” and the ‘ throb-
bing and pulsing stars,” as the bashful witnesses of some
illicit love affair, entertains or feigns an infinitely more
degraded conception of his relation to the Universe in which
he is placed, than the child who lisps at evening,—
“Twinkle, twinkle little star,
How I wonder what you are.”
For that wonder, which accompanies the little one in this
his first step towards the attainment of truth, will go hand
in hand with him, until in after years he may have sounded
all the known depths of the Cosmos. By-and-bye he looks
upwards to the Firmament in the night season with the
astronomer, and sees, in the luminous pathway which is
extended on high, an awful system of suns—a mist of suns
—of whose vast size and distance from each other, numbers
fail to impart to the human mind any conception. Hach
shining particle of that dense sun-cloud, he is told, wonder-
ing, is separated from its neighbours by sixty millions of
millions of miles. He finds that one such particle alone has
been measured, weighed, and analysed ;—it is a vast globe
wrapped in a sea of the intensest flame, well-nigh 3,000,000
miles around ;—that this vast furnace, this infinitesmal par-
ticle of sun-mist, is slowly moving across the cloud of its
fellow suns; yet though it should glance with the speed of
light for twenty thousands of years, its journey would still
be unaccomplished;—that this almost immeasurable Uni-
verse of suns is but a speck in a cloud of grander Universes
separated from each other by still more immeasurable wil-
dernesses of darkness extending into infinity for ever.
In those unfathomable abysses, he views the wheeling of

planets around their Suns in slowly rocking orbits,—of Suns
linked in circling round with their fellow Suns, blue, and
orange, and green, and crimson,—of Universe linked with
Universe, —of immeasurable rings and clusters, and com-
plicated spiral whirlpools, lustrous with countless myriads
of Suns. But who shall recount to him the unimaginable
mysteries of being,—of life, and mind, and soul, called forth
by the voice of the Almighty, around each radiant centre !—
Who shall report “ their holy triumphs out of evil wrung!”
—Who shall tell of the great Hosanna, arising throughout
these illimitable creations, for ever before the all-pervading
mercy-seat of God !
Again ;—this green duck-pond presents no inviting or
miraculous appearance. But the philosopher, still a wonder-
ing child, places a drop of its slime under the highest power
of the microscope, and a world of beautiful fish-like creatures
starts into view,—the green Euglenas. He notes the accu-
rate wave-lines of their taper forms,—the long, lashing
trunks by which they scull themselves along,—the brilliant
crimson eye-speck, which hints of a sense perhaps unknown
to man,—the wonderful provision made for their multiph-
cation and preservation,—how a single Kuglena, by inces-
sant self-division, becomes an infinite host,—how, when the
summer sun is drying up the puddle which is its Universe,
it seals up itself in a cell of horn, like the Indian Fakir, and
lies hard and dry in the mud, or floats a speck of dust upon
the breeze, until a welcome shower restores it to liberty and
life, when it creeps out of its cell again, not one, but a swarm
of little Huglenas.*
The filthy scum that coats the common sewer, and hangs
in long floating fringes from every stick and stone in our
Water of Leith, becomes in like manner transformed into
vast assemblages of the most wonderful and beautiful of all
animalcules,—into forests of Carchesium, each animal of
which is as amany-branched tree of glass,—each branch in-

Within the branching galleries of these sponges, uprooted
and driven landward by the hissing tide, lurk tiny Polythalms,
strange and beautiful forms, the microtypes of things that
lived inthecloudy dawnof earliesttime. Here theold Baculoid

wands and spirals of these many-chambered shells—each a
city whose indwellers are but little patches of shime. No
bright-eyed Nautilus puts forth its clasping arms from these
richly-sculptured habitations ; they are built up by a shape-
less and unorganised glair—a living glair, which streams as
a filmy network from all their thousand openings, and spreads
afar its glutinous meshes, whose touch is death—a formless
mystery, beneath whose plastic force lie moulding the solid
mountain chains and continents of a future world.*
Amidst the crannies and furrows of these stones and
broken shells, dredged from the deep, the wildest stories
of Arabian romance are imaged forth in facts of every-
day experience. From the delicate and fluted flasks of these

Again :—our philosopher, still a wondering child, can look
back with the geologist, and see “as in a glass darkly,” the
earth primeval and void, brooded over by the creative spirit
of the Almighty. He can view the traces of those mighty
elemental wars—those slow millions of years, that lifted the
land from the deep;—those slow millions of years, when the
early foliage was creeping over its denuded surface, and the
unfolding beauties of the radiata and the mollusc received

of the dragon reigned—when gigantic Saurians trailed them-
selves through the plashy marshes, darted fish-like through

instruments of death. Yet, looking back into the past, he
can also discern, as in a glass darkly, the future. He can
hopefully look forward to that glorious time when, as the
old Saurian reign has ceased, so the reptile reign of Sin
shall cease, and a renewed race, clothed in the majesty of
an innocent manhood, shall lift up their eyes radiant with
the indwelling Spirit of the Almighty, and look into the
deepest mysteries of God.

President's Address. 305
On the motion of Mr Alexander Bryson, seconded by Dr
M‘Bain, a cordial vote of thanks was unanimously given to
Dr T. S. Wright for his valuable services as President of the
Society, and for his learned and beautiful opening address.
Mr Bryson then called the attention of the Society to the
value of recording facts, however trivial they might seem,
and reminded the fellows that the discovery made by their
distinguished member, Mr Peach, and communicated to this
Society, of goniatites and other shells, near Durness, had
induced Sir Roderick Murchison to remodel his strategra-
phical arrangement of the rocks of Scotland.
_ Dr M‘Bain said that he was present when the first fossils
from Durness were shown to the Royal Physical Society,
and that the late Hugh Miller then considered them to be-
long to the Old Red Sandstone. At the same time, Mr
Miller observed that other fossils, in a more perfect state of
preservation, would probably be found in the same locality,
that would enable geologists to decide what formation they
belonged to. Dr M‘Bain also remarked that simple facts
might lead to important results in applied science as well as
in the higher generalisations; and stated an instance within
his own knowledge, to which the President had incidentally
referred, of the application of Melloni’s thermo-electric
thermometer, by their distinguished member, Mr A. Bryson,
to the detection of icebergs at sea, which might ultimately
be the means of saving an incalculable amount of life and
property.

1. On the Anatomy of Sacculina with a description of the Species. By
Joun Anperson, M.D. Plate XIII.
Three years ago I drew the attention of this Society to
the fact of the frequent occurrence of Sacculina and Pelto-
gaster on some of the Crustacea of the Firth of Forth. For
some years past the subject of the affinities of these parasites
has been occupying the minds of many foreign observers ;
and the following observations, therefore, are brought before
the Society in the hope that they may tend to throw some
light upon this difficult question. In the present paper I
have purposely abstained, as far as possible, from dogmatis-
ing regarding their systematic position, but elsewhere I have
referred them to the Cirripedes.* I may mention that the
relative position of the investing sacs, the character of the
ovaries and the ovigerous lamellee, and the apparent herma-
phrodite nature of the adult animal, when viewed in con-
nection with the larval form, appear to me clearly to indicate
their Cirripedial nature. Accordingly, in my graduation
thesis, I created a new order (Sacculinacea) for their re-
ception.
Among recent observers, Leuckart drew the attention of
naturalists to Thompson’s systematic description of Saccu-
lina, and proposed the adoption of his generic term. “If
we restore,” he says, “‘ the name Sacculina either for Pelto-
gaster in Rathke’s sense, or, at least, for the form character-
ised by Diesing as Pachybdella, we are only discharging an
old, superannuated debt.” In the same article he described
a new form parasitic upon Hyas araneus, and which he
named Sacculina inflata. In accordance with Leuckart’s
proposal, I use the term Sacculina as referring to the
parasite alluded to by Cavolini, and as synonymous with

The Larva, P\ Xi. fig. 1.
The larva, in the first stage, is oval, and presents no
marks of segmentation. Placed near the centre of the
anterior margin of the body is a yellow speck—the eye (a).
The ocellus is placed nearly in the centre of a dark-coloured
ring (6). Krohn, who has observed a structure similar to
this in the larva of a Balanide, regards it as the esophageal
ring. The lateral margins of the body, on either side of the
ocellus, are prolonged into two horns (c); and in this re-
spect the young resembles the Cirripedian larva in its first
stage. It is provided with three pairs of natatory legs: the
first pair (d) are situated immediately posterior to the horns
of the carapace; they are uniramous, are provided at their
extremities with bristles, and appear to be composed of two
joints; the second and third pairs (d’ d’) are larger than the
first, and are both biramous. The rami are furnished with
bristles. The under surface of the body is prolonged into
two spines (€ e), which project beyond the posterior margin
of the carapace. Besides these terminal spines, I have obser-
ved through the transparent body, two other structures (//),
which resemble very much the middle pair of spines described
by Darwin as occurring on the larva of Chthamalus stellatus.
The greater portion of the body is occupied by an oval mass
of nearly spherical globules (g). The various transforma-
tions of the larva remain yet to be determined.
The Adult Animal. Pl. XIII, figs. 10, 11, 12, 15.
According to the present state of our knowledge, this
parasite seems to be peculiar to the Decapod Crustacea.
All the specimens I have obtained have been attached over
the terminal portion of the intestinal canal (figs. 10 & 11 0’)
of the crabs on which they were parasitic, the females of
which they appear to infest more than the males. This
latter circumstance seems to be owing to the large size of
the purse of the female, as compared with that of the male
crab, affording them a better protection and means of
support.
The external sac (figs. 2,4 a)—The external skin is a
308 Proceedings of the Royal Physical Society.
tough, brownish-coloured, corrugated, and highly contrac-
tile structure. It is chiefly by means of this membrane
that the parasite is attached to the crab on which it lives.
The part which is attached to the crab forms a short ped-
uncle (b), but afterwards it suddenly expands to form the
external sac. The pedunculated portion (b) is very firmly
connected by means of a horny ring (d) to the skin which
invests the gut of the crab. The posterior extremity of the
sac remains open, forming a small orifice (c), which I have
called ovario-branchial.
The peduncle (b).—The external skin of this structure is a
continuation of the external sac (a), and contains within it
a prolongation of the parasite (£), which passes through the
horny ring, and rests upon the intestine of the crab. The
prolonged portion is tubular. In this arrangement we have
evidence for the parasitic nature of Sacculina, and are
entitled to regard the anterior portion of the peduncle as
the mouth. The mouth, structurally as such, is entirely
absent; and the only way the animal appears to derive
its nourishment is by this process absorbing the required
nutriment.
The ovario-branchial orifice (c) is sonamed from the two-
fold function it is supposed to fulfil in the economy of the
parasite. If a living Sacculina is carefully watched for a
few minutes, this orifice will be seen to open and contract
slowly, while a current of water may be seen to pass into
and out of the cavity of the body, the sac at the same time
alternately distending and contracting. The ova, when
fully developed, are extruded by this orifice, the structure
of which confines the water to the sac which contains them.
The orifice is situated upon the posterior margin of the
body, and is slightly raised above the level of the sac.
There is a constriction at its base, and a thickened por-
tion of the sac plays the part of a sphincter muscle. The
inner margin of the orifice is thrown into folds, usually
eleven in number, sometimes of a delicate and pellucid ap-
pearance. By this arrangement the orifice is capable of
great distention.
The corium (fig. 2 e).—On reflexion of the external skin we ©
On the Anatomy of Sacculina. 309
expose the underlying corium, which invests nearly the
whole inner surface of the sac. I have succeeded, in one or
two instances, in separating this membrane into two well-
marked layers. The external layer is a very thin membrane
investing the whole inner surface of the sac, attached at its
anterior extremity to the horny ring of the peduncle, and
posteriorly to the ovario-branchial orifice. I think it pro- |
bable, when the external skin is moulted, that its place is
supplied by this structure. The inner layer, following it
from the ovario-branchial orifice to which it is attached,
passes forwards, closely applied to the outer layer, till it
nearly reaches the anterior margin of the sac, where it be-
comes reflected on to the anterior portion of the peduncle,
and can be traced no farther as a separate structure. At
the left margin of the peduncle the corium is attached by a
septum (fig. 3 g) to a pulpy body embraced in the folds of
the ovigerous lamelle.
Organs of reproduction.—On opening Sacculina by an inci-
sion extending through the sac and continued from the
ovario-branchial orifice to the peduncle, we expose a pellucid
sac (fig. 4 2) filled with ova. This sac is found on both sides
of the pulpy body above referred to (fig. 2 h), which it em-
braces within its folds. The sac is merely a temporary
structure including the ova till their full development ; and
at this period I have seen the ovario-branchial orifice plug-
ged up by the extruded sac and its contents, and in. other
cases I have found it lying quite loose in the general cavity
of the parasite. In specimens like these, a delicate mem-
brane may be separated, by gentle manipulation, from the
inner surface of the corium and from the surface of the
pulpy body or internal ovaries. This membrane appears to
be an ovigerous sac, in the process of growth, destined to
receive a brood of ova, but, after their development, to be
cast off like its predecessor (fig. 5). The ovigerous sac ap-
pears to be continually present in one stage or another of
its development, so that the water which passes in at the
ovario-branchial orifice is never in contact with any other
structure. In a large specimen of Sacculina carcini, I found
two small mussels living in and attached to the inner sur-
310 Proceedings of the Royal Physical Society.
face of its ovigerous sac. The ova (fig. 6) are enclosed in
the sac, and are arranged in a racemose manner, enveloped
in a very delicate membrane.
The internal ovaries (figs. 2, 3, & 3’, h) are situated pos-
teriorly to the peduncle. They constitute an oval, flattened,
pulpy mass, dividing the cavity of the parasite into two
compartments; they are attached by the centre of their pos-
terior margin to the left wall of the ovario-branchial orifice;
and also, as previously mentioned, by the septum which
runs along the left side of the sac, they are connected to the
corium (fig. 2g). In the many specimens examined, I have
always found a small tubercle (figs. 2 & 3 0), with a minute
and apparently horny speck on its summit, placed on both
surfaces (figs. 3 & 3’, 0) of the body of the ovaries lying op-
posite to one another, a little to the left of the centre of its
posterior margin. On removing the little speck of horny
matter, a depression is seen in the centre of the tubercle,
apparently communicating with the substance of the ovaries.
May not these structures be the orifices of the oviducts,
closed by a temporary secretion of horny matter till the brood
of ova in the ovigerous sac has attained its full develop-
ment? This view of the nature of these tubercles has sug-
gested itself to me from the difficulty of accounting for the
passage of the ova into the ovigerous sac. The fact that the
ova found on the external surface of the ovaries are always
more fully developed than those further removed from the
surface suggests another view of the subject,—viz., that they
are developed in successive layers, and thus constitute the
ovigerous lamelle.
Situated immediately posterior to the peduncle, is a well-
defined cavity, lined by a special membrane, and containing
two oval-shaped bodies (6) placed side by side. These pel-
lucid sacs (figs. 7 and 8) contain in their cavities peculiarly
shaped bodies (c), and are provided with convoluted ducts
(a). The ducts appear to pass towards the right side of the
parasite (figs. 3 and 3’, h) along the anterior margin of the
ovaries, where they unite and become lost. From the close
relation of their ducts to the ovaries, it has all along appeared
to me that these vesicles probably play an important part
On the Anatomy of Sacculina. 311
in the generative economy of the animal. This opinion
seems to be strengthened by the fact that, on one occasion,
when examining under the microscope a portion of the
ovaries in the immediate neighbourhood of the vesicles, I
detected among their convolutions a tube identical in appear-
ance with the structure of their ducts. As yet, I have found
it impossible, from the soft nature of the tissues of these
parasites, to trace the ducts to their final termination ; but,
from the appearance of the tube above described, it seems to
me very probable that they terminate in the ovaries. The
walls of the vesicles are simply granular. A peculiarly
formed body (figs. 7 and 8c) is placed in the interior of
each of the vesicles, immediately over the opening of their
ducts. The portion of this body situated immediately over
the ducts (6) is of a brown colour, and apparently of a horny
consistence, and is terminated by three processes. The whole
structure (fig. 9) is extruded when pressure is applied to the
vesicle. May not these vesicles represent the testes and
cement-glands of these parasites ?
These observations have been made from dissections of a
new species, parasitic upon Cancer pagurus: it differs in its
anatomy from Sacculini carcini in the form and position of the
vesicles. In the former species these organs are oval, and
placed immediately posterior to the peduncle, while in the
latter they are elongated (fig. 16), and buried in the left an-
terior angle of the ovaries.
The relation of the septum to the surrounding structures,
and the double nature of the ovigerous sac, hypothetical
oviducts and testes, indicate a tendency to bilateral sym-
metry.

It is bilobular in form, its greatest diameter being in the
transverse direction. The figure given by Cavolini of the
parasite he described exactly corresponds with this species.
It varies greatly in size, and is undoubtedly the largest
known species of these parasites. Some of my specimens are
an inch in breadth. The skin, in the generality of specimens,
is of a brownish-yellow colour, and is minutely corrugated.
This species has a wide geographical range. Cavolini
obtained his specimens from the shores of the Mediter-
ranean; Rathke first met with it in the Crimea, and after-
wards in Norway; Schmidt found it in great abundance at
Wangerooge, and he also obtained specimens on the Dalma-
tian coast ; Steenstrup’s specimens were from the Mediter-
ranean and from the ‘“ Black Banks” in the North Sea.
From the observations of Thompson, this parasite appears
to be of frequent occurrence on the Irish coast. Some years
ago I found this species for the first time in the Firth of
Forth, but not nearly in such numbers as the following
one. wat
Sacculina triangularis, nu. sp., figs. 4, 11, 14.
Diagnosis.—Triangularis est, gregaria, raro sola; maxima diametro

This species is usually gregarious; sometimes as many as
five individuals may be found huddled together and strug-
gling for existence. I have never found it on any other crab
than Cancer pagurus. Of the two species of these parasites
found in the Firth of Forth, this is by far the most common:
in some localities along the coast, to find a crab free from
it is the exception.
The form of the animal is triangular. The greatest diame-
ter is in the longitudinal direction,—~.e., from its attachment
to the posterior orifice. Besides differing in its external cha-
racters from Sacculina carcini, it also differs from it, as al-
ready noticed, in the form and position of the vesicles.
I am indebted to Professor Goodsir for a specimen of this
parasite found in the collection of his lamented brother, the

large, globular, or slightly pear-shaped, containing each a
single medusoid. Height of polyp about ~jth inch.
Medusoid with a moderately deep subglobose umbrella,
having four golden-yellow radiating canals, at the bulbous —
bases of which, on the margin of the umbrella, are four
rather short tentacles; four shorter ones alternate with
them; and intermediate between these are eight others,
almost tubercular. The peduncle is rather long and co-

A single specimen only of this interesting little Hydrac-
tinia was obtained, parasitical on a dead shell of Natica
Alderi brought in by the fishing-boats at Cullercoats. I
have since seen a dead and rather worn specimen, upon
Natica Grenlandica, among the Zoophytes collected in
Shetland by the Rev. A. M. Norman. The species differs
from H. echinata in its much smaller size, the simple linear
form of its spines, their irregular grouping, and more espe-
cially in its bearing medusoids; these latter spring from
the encrusting base. No capsule could be detected ; but this
might possibly arise from its great transparency. The me-
dusoids bear a great resemblance to those of Podocoryne
carnea (Sars), the only difference being in their having eight
intermediate tubercular tentacles. In this respect they also
differ from the medusoid of a Hydroid polyp described by
Professor Lovén, and referred by him to Hydractinia, but
which appears rather to belong to the genus Podocoryne,
as the base was not horny or spinous. As far as 1 am
aware, therefore, this is the only instance in which medu-
soids have been ascertained to be produced by a true Hy-
dractinia. 7
2. Atractylis arenosa, nu. sp. Pl. XIV. figs. 5-7.
Polypary minute, consisting of a creeping fibre, from
which arise short funnel-shaped tubes, rather irregular in
form, but always expanding more or less at the top, from
which the polyps issue, generally covered with minute
grains of sand. Polyps entirely retractile, with long,
slender, strongly muricated tentacles, varying in number,
according to age, from six to twelve.
The genus Atractylis has been established by Dr Strethill
Wright for a group of Hydroid Zoophytes resembling Fw-
dendrium in many of their characters, but differing in the
conical form of the mouth of the polyp, and its retractility
(partial or complete) within the tubular polypary. They
are generally of small size, and seldom branched. Their
reproduction is usually by medusoids ; but Dr Wright, who
316 Proceedings of the Royal Physical Society.
has lately met with the present species in the Firth of Forth,
has ascertained that it produces planuloid young direct from
the summit of the ovarian sac. This affords another proof
of the difficulty of establishing a genus from the mode of
development.
I have met with this species occasionally, for some years
past, on stones and the roots of Laminarie at Cullercoats
and Tynemouth. From its minute size, it, requires to be
carefully looked for.

III. On Reproduction in Adquoria vitrina. By T. Srreruity
Wricut, M.D. Plate XV.
In vol. i. of Agassiz’s ‘‘ Natural History of the United
States,” the following passage occurs :—‘‘ As to the Auquo-
riadee, I have no doubt that they are genuine hydroids,
though I have not been able to trace with certainty the
origin of the AXquoria of our coast to any true hydroid.
But the structure of Aiquoria in its adult Medusa state is
so strictly homologous to that of all the naked-eyed Medusz,
that even if it were ascertained that it undergoes a direct
metamorphosis from the egg to the perfect Medusa, I would
not. hesitate to consider it as a member of the order of
Hydroids, since it has simple radiating aquiferous tubes, a
circular canal, and marginal tentacles closely connected with
it, and provided with minute pigment spots at the base.”
Agassiz was doubtless correct, and he might also have pre-
dicted that it belonged to the genus Campanularia or Lao- ©
medea, as it corresponded with those genera in the presence
of otoliths. In the beginning of this month (November)
Mr Fulton sent me two living specimens of Aquoria vitrina,
one about three inches in diameter, the other about six

inches and a half. The number of lips of the latter was
about forty, the radiating canals, each having a long ovisac;,
about eighty, and the marginal tentacles, by estimation,
four hundred. On examining the ovaries, I found that the
egos were hatched, and the young, in the form of almost
invisible planule, were issuing from the ovisacs. These
were gently extracted with a glass syringe, an instrument
so useful to those who practise the obstetric art amongst the
hydroide, and were placed about three weeks ago in glass
tanks of clean sea-water prepared for their reception. Many
thousands of larvee were placed in the tanks, and of those,
about a score have been developed into Campanularian
polyps; about a hundred are still progressing to that end,
and the rest have disappeared. It was with no little
impatience and anxiety that I saw the Planula during a
fortnight fix itself to the glass, spread itself out into a short
thread, secrete its scleroderm, put forth its polyp-bud—this
last slowly swelling day by day, until at last it opened,
and a polyp appeared, furnished with twelve alternating
tentacles, joined together for about one-third of their length
by a web, the polyp enclosed in a cell terminating in many
acuminate segments. It is now about six years ago that I
was watching, in like manner, the slow evolution of a bud
from a Campanularian Zoophyte, the Laomedea acuminata
of Alder—the Campanulina of Van Beneden—the bud
opened, and a bright green medusoid issued forth, having
four lips and two tentacles. The polyp form of Mquoria
vitrina is, as far as I can determine, identical with that of
L. acuminata in shape; but is so excessively small—quite
invisible to the naked eye—that we must wait for further
development before we can determine their identity. Ge-
ganbaur has proved that the Medusoid of Velella acquires a
further number of canals and tentacles; and I have else-
where recorded the successive changes which occur in the
Medusoids of several species of Atractylis. It is also certain
that such increase in the number of elements does occur in
Aiquoria vitrna, for the smaller specimens have always a
less number than the larger. Meantime, the question as to
the larval state of A/quoria vitrina is settled. This, the

IV. The following Objects of Natural History were exhibited by
Epwarp CHarteswortH, Hsq., York.
A stuffed specimen of the Frilled Lizard Chlamydosaurus Kingii,
from Port-Nelson, New Zealand, believed to be the best example yet seen
of this most extraordinary reptile. It was purchased at the;sale of the
late Dr Mantell’s Museum.
A small but extraordinary coral from the Chinese Seas, believed to be
undescribed.
A series of small fossil tertiary shells from Barton, in Hampshire, illus-
trated by magnified figures.
A collection of small recent British Marine shells, illustrating a new
mode of mounting and exhibiting very small specimens, intended to in-
sure safety with effective display. The shelis were fixed on cards with
gum tragacanth, which can be freely brushed across the surface, and
thus save much time in mounting, as it does not shine when dry, like gum
arabic. ‘The cards are then put in small boxes with glass lids. =
A specimen of Mactra Helvacea, and other shells from the Channel
Islands; several rare fossils of various kinds were also exhibited.

It was moved by George Logan, Hsq., that on account of
the deeply lamented death of H.R.H. the Prince Consort,
the Society do adjourn to the fourth Wednesday of January.
The motion was unanimously agreed to; Alexander
Bryson, Hsq., making the following remarks from the
chair :—
Gentlemen,—I cannot close the meeting of the Society
without giving expression to feelings which I know animate
the breast of every Briton. Never in my own remembrance
has such a sensation been experienced as that which thrilled
through the kingdom yesterday, when the people learned
that their beloved Queen was a widow. The late Prince
Consort was among the few of the great and distinguished
who honoured himself by honouring our pursuits by his
appreciation and knowledge of them. We must ever feel
how much our country has been indebted to Prince Albert
for many institutions cognate with our own, and it is to me
a satisfaction, though a melancholy one, that he was enabled
to do so much good work.
Mr William Turner, M.B., begged that before the Society
adjourned, he might be allowed to exhibit some moist pre-
parations he had brought in illustration of his paper, as they
could not be preserved and again exhibited. Mr Turner's
request was agreed to, and the following communication was
laid on the table :—
I. Upon a Non-striped Muscle connected with the Orbital Periosteum of
Man and Mammals ; and Notes on the Musculus Kerato-cricoideus.
By Witi1am Turner, M.B. (London), F.R.S.E., Senior Demonstrator
of Anatomy, University of Edinburgh.
Whilst engaged in making a dissection, in the human
subject, during the winter session of last year, of the
Superior maxillary, or second division of the fifth cranial
nerve, my attention was attracted to a pale-reddish, soft
mass, filling up the narrow chink of the spheno-maxil-
lary fissure, and extending from the sphenoidal fissure in
VOL. I. 2T
320 Proceedings of the Royal Physical Society.
the sphenoid bone to the infra-orbital canal in the superior
maxillary bone. It was evidently connected to the superior
(ocular) aspect of the periosteum of the orbit, and it was
pierced by the orbital branch of the superior maxillary nerve,
from which, as well as from the ascending branches of the
spheno-palatine ganglion, it appeared to receive its supply
of nerves.* It completely shut off the superior maxillary
nerve, with its infra-orbital continuation, from the cavity of
the orbit.
Since the period of making the above observation, I have
availed myself of several opportunities of examining the
same region in other subjects, and have constantly observed
appearances of a nature similar to those just described.
The amount of the reddish mass, and the depth of its tint,
varied slightly in different instances. Frequently it was so
pale as scarcely to attract attention, which may perhaps be
the reason why it has so long been neglected by anatomists.
When carefully examined with the naked eye, or, still
better, with a single lens, it was seen to exhibit a fibrous
appearance. A -small portion snipped off with scissors,
teased out with needles, and placed on the stage of the
microscope, under a quarter-inch objective, was observed to
be composed of pale, flattened, band-like fibres, having a
faintly granular aspect, and presenting indications of elon-
gated nuclei at intervals. From these characters I had
little doubt that the structure in question consisted of the
non-striped form of muscular fibre.
As considerable difficulty is always experienced in obtain-
ing for examination the contents of the human orbit, in a
perfectly fresh condition, I, in the next instance, proceeded
to dissect the orbits of some of the more readily obtained
mammals, with a view of ascertaining if a similar structure
existed in them. In the orbit of the sheep, I have most
satisfactorily observed appearances which have fully con-
* That Meckel’s ganglion sends branches to the periosteum of the orbit isa
fact that has long been known to anatomists, though there have been difficulties
in the way of giving a satisfactory reason why such an arrangement prevails.
The existence of the small muscle now described accounts for the distri-
bution.
On a Non-striped Muscle of the Orbit. 321
firmed the opinion of the structure already expressed. The
orbit of this animal differs from that of man in possessing
much less perfect walls. As a consequence of this, the
orbital membrane, or periosteum, is a structure of much 1m-
portance, for it stretches across the floor of the orbit from
its outer to its inner wall, extends backwards to the optic
foramen, and completes the boundary of the cavity at the
spot whee the bony wall is wanting.
If the contents of the orbit be carefully removed, and the
orbital membrane examined from above, it will be seen to
be a well-defined structure, distinctly fibrous, and in many
places having an almost tendinous-like aspect. Intimately
connected with, and forming an essential part of it, 1s a thin
layer of a pale reddish substance, which extends across the
greater part of the floor of the orbit, passing backwards to
the optic foramen and sphenoidal fissure. In close contact
with this structure, especially at the posterior part of the
orbit, is a well-marked vascular net-work, sufficiently injected
with blood to be distinctly visible. This vascular plexus
constitutes a small rete mirabile, connected with the oph-
thalmic artery. By removing a small portion of the reddish
mass, teasing it out with needles under water, and examin-
ing it with a quarter-inch objective, it may be seen to be
composed for the most part of flat, pale, non-striped fibres,
collected together in bundles, having a faintly granular
aspect and exhibiting decided indications of nuclei in their
interior. These bundles of flat fibres are mingled with
ordinary fibrous tissue, both white and yellow, the latter be-
coming more distinct after the addition of acetic acid. The
pale, non-striped fibres have all the characters of the in-
voluntary muscular fibre. Being desirous, however, of ascer-
taining if these fibres could be resolved into their con-
stituent fibre-cells, I adopted the plan which has been
recommended by feichert, and macerated a portion of the
orbital membrane for forty-eight hours in dilute hydro-
chloric acid. I then found that, by the aid of a very slight
dissection, the fibres readily resolved themselves into the
elongated fusiform cells of which they were composed. In
no tissue which I have ever examined, consisting of the
322 Proceedings of the Royal Physical Society.
non-striped muscle, have I succeeded in obtaining more
beautiful and more perfect specimens of the contractile
fibre-cell than in this muscle of the orbital membrane. The
fusiform shape of the cells, their size, and the elongated
rod-like nucleus in the centre of each cell, gave to the tex-
ture a most characteristic appearance. I may also mention,
that when the orbital muscle in the sheep was examined
without the addition of any re-agent, besides distilled water,
a number of elongated rod-like nuclei were always met with,
lying free in the water surrounding the preparation, which
had evidently been loosened and detached during the dis-
section with the needles. These nuclei corresponded in
their characters to those met with in the interior of the
fibre-cells. The characters which I have now enumerated
render the muscular nature of the reddish texture connected
with the orbital membrane sufficiently clear.*
On referring to the authorities who have written on the
structure of the orbital membrane, I find that the following
opinions have been expressed concerning it :—
Bendz,t in a paper ‘‘On the Orbital Membrane in the Do-
mestic Mammals,” describes it as distinctly fibrous, but pos-
sessing a considerable quantity of a yellowish tissue, which he
considers to be elastic, interpolated with it. He regards the
opinion, which had been previously advanced by Gurlt, that
the tissue was muscular, to be erroneous.{ Stannius states
that in those animals in which the bony wall of the orbit is
incomplete, the separation between the orbital cavity and the
temporal fossa is mostly effected by a fibrous membrane
containing also abundant elastic tissue. He states that
Rudolphi regarded these elastic fibres to be muscular in
Bears, and that Meckel described a muscle in the orbital
membrane of Ornithorynchus.§ Chauveau speaks of the
* Since this paper was communicated, I have dissected the orbit of a red
deer (C. elaphas), and found the orbital muscle very strongly developed in it.
Not merely did it constitute a large extent of the orbital periosteum, but it
possessed a very decided reddish colour. In young human subjects J have also
observed it very well marked.

fibrous membrane which completes the cavity of the orbit as
entirely composed of white inextensile fibres. Gurlt* con-
siders it to be a strong fibrous membrane, with yellow elastic
fibres interpolated. H.Muller,t in avery brief communica-
tion, states that he has found flat muscular fibres in the
inferior orbital fissure in man, and corresponding structures
connected to the membrana orbitalis of mammalia.
It was supposed by those, who held that the membrana
orbitalis was a highly elastic and not a muscular structure,
that it was through its elastic recoil that the eye-ball was
reprotruded in those animals which retracted the ball,
through the contraction of a retractor muscle. H. Muller,
again, who speaks more positively than any who have pre-
ceded him, not only of the existence of a muscle, but also
of the kind of fibre of which it is composed, considers that
it antagonises those muscles which retract the eye-ball into
the socket, and that thus, the reprotrusion of the globe is
produced, not by a mere elastic recoil but by a muscular
contraction.
If this hypothesis be correct, an arrangement exists in
this locality which is certainly to be regarded as an unusual
one,—viz., an involuntary muscle acting as a direct anta-
gonist to a voluntary muscle. Whether the hypothesis be
correct, or not, | am disposed to consider that the muscle
has some especial relation to the vascular arrangements in
the orbit. Its extension backwards to the foramina through
which the orbital vessels proceed, and with which it is in
immediate relation, and the very abundant vascular network
found in connection with it, point, | think, to some special
relation between the muscle and the vessels, a relation which
is not at all inconsistent with what is known of the function
of non-striped muscle in other localities.
Note.—Since the above paper was in type, my attention
has been directed, by Professor Huxley, to a communication
by H. Miller, dated Dec. 15th, 1860, entitled “On the
Influence of the Sympathetic upon some Muscles, and on the

extensive Occurrence of Unstriped Muscles in the Skin in
the Mammalia.”*
As this paper throws some additional light upon the pro-
bable action of the orbital muscle, I append a short abstract
of it :—
H. Muller, after referring to the many puzzling questions
which have arisen respecting the function of the sympathetic
nerve, and its relations to the muscles supplied by it, pro-
ceeds to ask two questions :—
1st, Whether and which unstriped muscles are supplied
by other nerves than the sympathetic ?
2d, Whether and which transversely-striped muscles are
under the influence of the sympathetic ?
In answer to the first, the action of the oculo-motor nerve
upon the unstriped fibres of the iris cannot be doubted; the
vagus also acts upon unstriped muscles, and the experiments
of Schiff have shown that the greater part of the vascular
nerves are not connected with the sympathetic.
The second question may be most effectively answered by
considering the effect produced upon the eye-ball by division
or irritation of the cervical sympathetic. Muller, for this
purpose, refers to the experiments of Bernard, R. Wagner,
and Brown-Sequard ; the general tendency of which is to
show, that division of the cervical sympathetic produces
narrowing of the palpebral fissure, retraction of the bulb,
projection of the ‘nictitating membrane and narrowing of the
anterior nares and the mouth. Irritation of the nerve by
galvanization, on the other hand, produces increase of the
opening of the lids, projection of the bulb, retraction of the
nictitating membrane, relaxation of several facial muscles.
Respecting the causes which produced these changes there
was some difference of opinion. R. Wagner could scarcely
conceive that any force, save the contraction of the two
obliqui, could produce projection of the eye-ball, and yet,
he asks, “‘ how could these transversely-striped muscles re-
ceive excito-motory fibres from the sympathetic ?” Brown-
Sequard, again, considered that retraction of the bulb, after
* Ueber den Hinfluss des Sympathicus auf einige Muskeln, &. Von H.
Miiller, “‘ Verhandlungen der Phys. Med. Gesellschaft in Wurzburg.”’
On a Non-striped Muscle of the Orbit. 325
section of the nerve, was produced by the active contraction
of the retractor and recti, and that its reprojection by sub-
sequent irritation was areposition. Schiff regarded the pro-
jection of the bulb as due to the action of the obliqui: the
movements of the lids he considered to be passive, and due
to those of the bulb.
Remak, on the other hand, believed that the narrowing of
the palpebral fissure was due to a relaxation of the levator
palpebree superioris, accompanied by a spasmodic contraction
of the orbicularis. Moreover, he conceived that the sym-
pathetic acted upon the voluntary muscles of the lids about
the eye.
Muller considers that 1t is now no longer necessary to dis-
cuss the various probabilities respecting the influence of the
sympathetic upon the voluntary muscles of the eye, as a
complete series of unstriped muscles have now been ob-
served, which will serve as a foundation for explaining the
movements in question.
These muscles consist of three divisions :—
1st, In the orbital cavity of mammals, a membrane (mem-
brana orbitalis), consisting of unstriped muscles with elastic
tendons, exists, which, by irritation of the cervical sympa-
thetic, projects the contents of the orbit, especially the bulb,
forwards. Retraction is produced by the transversely-striped
retractor. In man, the orbital muscle ig much reduced in >
size, and the retractor is wanting, so that a distinct projec-
tion of the bulb does not follow irritation of the sympathetic,
as Wagner and H. Muller himself have observed.
2d, The projection of the nictitating membrane in mam-
mals is mostly due to the retractor bulbi under the influence
of the N. abducens. Its withdrawal depends on some un-
striped muscles which are under the influence of the sym-
pathetic. In hares, however, the withdrawal is due to a
transversely striped muscle, which is not supplied by. the
sympathetic but by the oculo-motorius. In man, the lid
and its muscles are rudimentary.
od, The upper and lower lid possess in man, and in very
many mammals, unstriped muscles, which have the power
of drawing them back. They are more feeble in the upper
326 Proceedings of the Royal Physical Society.
than the lower lid, so that by irritation of the sympathetic
the latter is drawn back in a more marked manner than the
former. Narrowing of the palpebral fissure, after section of
the cervical sympathetic, depends upon relaxation of these
muscles. Yet recession of the eye-ball may depend upon
relaxation of the orbital muscle. Muller, then, concludes
that the movements occasioned by experimenting on the
cervical sympathetic are not such as to entitle us to infer
an influence of that nerve upon voluntary striped muscles.
He also considers that the movements about the nose and
mouth, said by Bernard to be produced by section of the
sympathetic, if they do take place, are owing to the presence
of unstriped cutaneous muscles.
Miller next inquires into the existence of unstriped
muscles in the skin of the ear. He has occasionally found,
on galvanizing the cervical sympathetic in cats, that a move-
ment of the hairs growing upon the skin at the entrance of
the concha has taken place. This experiment has, how-
ever, frequently failed both in cats and other animals. A
careful examination of the skin of the part did not give any
indications of unstriped muscles, but very distinct muscles
were seen connected to the hair follicles. He considers
these experiments of interest, as they appear to indicate
whence the muscles of the hair follicles receive their nerves.
Owing to the movement of the hairs being limited to a very
small locality, during the irritation of the sympathetic, one
must suppose that only a very small part of the unstriped
muscular apparatus of the skin of the cat can be regulated
by the cervical sympathetic.
Notes on the Occurrence of the Musculus Kerato-cricoideus.
—In a paper, entitled ‘‘ Remarks on the Musculus Kerato-
cricoideus (Merkel’s Muscle),” read to this Society in Janu-
ary 1860 (see Proc., vol. ii. part 1, page 135), I directed
attention to an account which had been given by Dr Carl
Merkel of Leipsic (Stimm und Sprach-Organ, 1857), of a
hitherto undescribed muscle of the human larynx. Merkel

of the cricoid cartilage, and extending obliquely upwards —

and outwards to be attached to the posterior margin of the
inferior horn of the thyroid cartilage. He stated that the
muscle was not found in every larynx, and that when pre-
sent it existed only on one side.
In my remarks, I supplemented the description of Merkel
with some additional particulars, more especially pointing
out, that, although, as a rule, the muscle only occurred on
one side, right or left, as the case might be, yet that a double
muscle might exist. I figured an example of such a bilateral
muscle, which at that time was the only one I had seen.
Since then I have met with two additional cases in which a
double kerato-cricoid muscle was present. One of these was
especially note-worthy, for the muscle, on both sides, was
more largely developed than in any previous example that
had fallen under my notice. The great size of the kerato-
ericoid muscle was combined with a general laryngeal mus-
cularity. The occurrence of three examples of a double
kerato-cricoid muscle, during the last two years, within my
own experience, shows that the bilateral arrangements is
not so unusual as was in the first instance supposed.*

Notes on the Habits of the Beaver. 329
The following Communications were then read :—
1. Notes on the Habits of the Beaver. By an Hye-witness, Jamxs
M‘Kenzisz, Esq., an Officer in the Hudson’s Bay Company Service.
Communicated by Anprew Murray, Esq.
The Beaver is found over a wide extent of country on the American
continent, extending east and west from the Atlantic to the Pacific, and
probably from Lat. 48° to 54° north ; but on the slopes of the Rocky Moun-
tains, where the climate is comparatively mild, he is met with much
further north and south. My object, however, is not so much to define
his geographical limits, as to make a few notes on his habits. Beavers
build occasionally on the shores of lakes, but prefer the banks of rivers and
streams. ‘They go generally in pairs; and having selected a convenient
site near the banks of the river, the two clear a circular piece of ground,
generally 6 feet in diameter, carefully removing everything on the sur-
face. This done, they carry in their arms, walking on the hind feet, 5
to 10 Ibs. of strong clay from the river, and deposit it to a width of 2 feet
all round the circle, thus making the diameter 4 feet ; then collecting long
grass or branches of willow, they mix up the whole welltogether, so as to form
a good foundation, In this way they build the walls to a height of about
10 feet, gradually narrowing ; and the whole has a rounded form, some-
what like an oven. Unless they had some means of plastering or smooth-
ing down the mud walls, the rain would certainly wear them away in a
short time ; and although it is supposed that the beaver never uses his
tail as a trowel, I have it from the authority of eye-witnesses that he does
so—in fact, Nature has furnished the animal with the tool ready made to
his hand. After he has laid the foundation, and, indeed, in process of lay-
ing it, before the clay gets dry, he uses the trowel; and when the wall is
raised to a certain height, he goes round the circle, carefully plastering
every load he carries from the river and lays on his house. The lodge
has neither doors nor windows, and the finishing hand is not put to it till
he is far advanced with his bridge, or perhaps until he has completed it.
Before the house can be completed, a subterranean passage is excavated
from its centre to the dam or pond, and this at a depth varying from 2 to
6 feet, depending on the difference of level between the river and house.
He then strews his floor with thin strips of willow tree, cut by him in the
form of carpenter's shavings, for his winter's bed. The construction of
the bridge shows even more ingenuity than the construction of the house,
and is of various lengths, depending on the size of the stream. When
only a few feet wide, the wall goes straight from bank to bank at right
angles to the current; when larger, or about 40 feet wide, it is formed of
a single curve; but when the river to be bridged is from 100 to 120 feet
wide, the wall is formed into a series of curves, or undulations as it were.
He understands pretty well the properties of straight and curved lines in
his engineering works, and knows the mode best suited to the circum-
stances in which he is placed. If his domicile is situated on a wide stream,
he adopts that mode of construction which is best adapted to withstand
the pressure of a great body of water and ice on the opening of the naviva-
tion in the spring. The wall is about 12 feet high and 9 feet wide at
bottom, but on the side exposed to the current it slopes with the stream,
forming, perhaps, an angle of about 40°. At any rate, while the wall is
about 9 feet wide at bottom, it is only 1 foot wide at top. He selects
for the foundation pieces or logs of timber which are water-soaked ; but
if he cannot find enough of these, any wood, either green or dry, will do,
covering them with large stones, to prevent their rising to the surface.
But logs thus placed on one another across a stream could not be so well
330 Proceedings of the Royal Physical Society.
fitted together as to prevent the passage of the waterbetweenthem. 'Tomeet
this difficulty, he plasters the side of the wall exposed to the current with
a coating of clay some 2 or 3 inches in thickness; and this clay, as he has
to travel through the water with it, he carries not in his arms, as in the
construction of the house, but on his head, supported by hisarms. There
is no doubt that the side of the wall exposed to the current is thus clayed,
although I cannot well understand how it could withstand the action of
the water for any length of time. If he bridged the stream in this way
and clayed his bridge, it is clear that he would have always a large quan-
tity of water flowing over the top, which would impede his operations ;
and, to obviate this difficulty, he leaves an opening at either end for the
passage of the water, to be shut up afterwards. Having finished the wall,
the next thing to be done is to collect his winter’s supply of food. This
consists of the bark of the ash, the bark and leaves of a certain kind of
poplar, the bark and leaves of some kind of willows, and the fruit of the
alder. A large poplar tree of about a foot in diameter, two beavers can
cut down in half an hour’s time. It is afterwards cut into lengths of
about 5 feet; and when he has got enough, he makes a road to the stream
from 3 to 6 feet wide, by cutting down trees or shrubs which may be in
his way. If the road be inclined towards the stream, he rolls the wood
down before him; but if it be level, or nearly so, he takes hold of the
wood by his teeth, and carries it forward. In the water he always trans-
ports wood or branches from one spot to another in a similar manner.
His wood will, of course, float in the water, and, if left to float, would
soon become embedded in the ice, which in ordinary winters, in this cli-
mate, is about 5 feet in thickness ; he therefore takes it to the bottom of
the dam, which has a depth of water of from 10 to 12 feet, and either
fastens it on end in the mud, or covers it with stones, to prevent its rising,
and it will thus at all times be available for his purpose. He is now
nearly ready for the long winter. There is, however, something more to
be done. I have mentioned that he digs a subterranean passage from his
house to his dam; on each side of this, and in some instances widely
apart, he makes holes about 5 or 6 feet in the bank, generally communi-
cating in the interior with one another, and with the main entrance to
the lodge. In one of these he takes his food, for he seldom or never eats
where he sleeps.
The female has generally from three to six young at one time; the
period of gestation is four months; and the young are produced, or first
see the light, about the middle of May, and in the following August
_assist in building the lodge. The young and old work together. When
about a year old, they start in pairs to form new settlements, provided,
like the best of colonists for a new country, with nothing else but good
strong limbs and a fine set of teeth. Ifthere be an odd-fellow, he goes on
his travels alone, and forms a small bachelor establishment for himself for
the winter, unless, indeed, he meets a friend with kindred sentiments by
the way. Sometimes two of the year-olds remain in the old house for
another year, in which case the family in the following May is a large
one, never, however, numbering more than twelve individuals. The
usual number found in a lodge is from four to eight. They never build
their lodges close together—they are generally from a quarter to half a
mile apart. This no doubt arises from the circumstances that they cannot
well dam the rivers or streams, and find a sufficiency of food, at shorter
distances. The beaver remains shut up for the whole winter; during the
day always asleep, and during the night taking his bath and his meals. In
spring, however, he sometimes makes a hole in the ice to have a look at
the country around him. Ido not know how he manages to do without
air; so far as I could discover, there are no air-holes about his premises.

J Anderson MD, ai? HOLOTHURIA .
On an apparently New Form of Holothuria. Sal
In the coldest weather, the top or roof of the lodge is always moist or wet,
while the sides are frozen, at least outwardly. It is certain that he can
remain under the water for halfan hour at a time. He lives in the same
lodge for two or four years, when, finding his food scarce, he removes to
another locality, and builds as before.
For instinct or intelligence he is at the head of the wild animals in this
country, and lives longer, I believe, than any of them. Other animals,
as for instance the young of the American hare or rabbit, the marten and
lynx, perish by thousands in the spring, either by cold, or in seasons of high
water, or from lack of their ordinary food ; but it is all the same to the
beaver whether the season be wet or dry, hot or cold—the shores of every
lake and the banks of every river furnish him with abundance of food.
I do not know whether he will thrive in Britain; atany rate, the Zoolo-
gical Gardens is not the best place for him; he is fond of solitude, and
dees not like company. An island with a large lake would be the most
eligible place for him, where, if set at large, he would soon shift for him-
self. Of course, his usual food would require to be found on the spot.
Dr J. A. Smith said, with regard to Mr M‘Kenzie’s statement that he
could discover no air-holes in the lodges of the beaver, and wondered
how they managed to do without air; it was probable the air got
access through the comparatively looser structure of the top of the lodge,
which Mr M‘Kenzie states is always moist or wet even in the coldest
weather, while the sides are frozen outwardly.
II. On an apparently New Form of Holothuria, By Joun Anprrson,
M.D. Plate XVI.
In the autumn of 1859 I dredged, from 5 fathoms of water
in Bressay Sound, Shetland, the Holothuria which forms the
subject of this memoir (Plate XVI. fig. 1). It was clinging
to the inside of a dead and half-open Modiola vulgaris. When
captured, it was of a cream-colour, slightly speckled with
brown; but since it has been in confinement, it has sensibly
deepened in colour. During the first months of its imprison-
ment it was very lively, especially at night; during the day,
when exposed to the light, it always contracted itself into a
_hittle ball, confining itself to one spot, and that the one ex-
posed to sun-light. The tentacles were always exposed at
night, but were immediately retracted whenever any attempt
was made to examine them. About the beginning of the
second month of its confinement it became more sluggish,
and remained for days contracted, never displaying its ten-
tacles even at night. The body contracted so firmly upon
itself, that many of the feet by which it was attached gave
way, and were left sticking to the sides of the glass vessel in
which it was confined. After remaining in this condition
for some time, the integument about the centre of the body
332 Proceedings of the Royal Physical Society.
at last ruptured, and through the opening a portion of the
viscera were protruded, which ultimately sloughed away ;
at the game time a considerable portion of the external skin
desquamated, the animal not appearing to suffer much from
the process, for the opening healed shortly afterwards. The
animal has been kept in a small shallow vessel of sea-water,
with only a little piece of sea-weed in it to keep the water in
good condition. During by far the greater part of the nine-
teen months of its confinement it remained contracted,
seldom moving from one spot. The only food it could pos-
sibly have obtained must have consisted either of micro-
scopic animalcules or the spores of Alge. The animal is
still alive; and I am therefore not in a position to say any-
thing regarding its internal structure.
The dorsal region of the body, when the creature is con-
tracted, is of a deep purplish-brown tint, but the ventral
surface is of a paler hue. The dorsal surface, when the
creature is distended, approaches very much to the colour
of the ventral aspect when in a state of contraction.
When contracted, it is little more than a quarter of an
inch in length, and about the fifth of an inch in breadth ;
but when distended and moving about, it becomes double
this length, and its breadth also is slightly increased.
The five double rows of sucking-feet are unsymmetrical,
the two dorsal rows being irregular in their distribution.
The dorsal feet are much less numerous than the ventral,
which they greatly exceed in size, and from which they
differ very much in their undilated tips, and by their being
seated in some instances upon rounded eminences or tuber-
cles of considerable size. These feet are capable of com-
plete retraction into the tubercles. Though the two dorsal
rows of feet differ very much from the ordinary arrangement
_of these organs in the Holothuriade, we can nevertheless
trace faint indications of the double character of the rows.
The three double rows of ventral sucking-feet are fully de-
veloped; the feet are placed opposite to one another, and are
dilated at their tips, but are only partially retractile. The
animal walks upon the three well-developed rows; and if
turned upon the aborted ones, it immediately recovers itself,
On an apparently New Form of Holothuria. 303
and turns round to what appears to be its ventral surface.
In the anomalous genus Psolus, as is well known, the loco-
motive organs are restricted to a small flattened ventral disk,
on which the three developed rows of feet are disposed.
The arrangement of the feet in the animal under consider-
ation is another instance of a like specialization of function,
and indicates the tripod nature of the Holothurie. Viewed
thus, this little animal is fraught with interest, and may
serve to connect, by its gradation of form, the genus Holo-
thuria, with its five well-developed rows of locomotive feet,
and the genus Psolus.
The tentacles (Pl. XVI. fig. 2) are ten in number ; eight of
them are long, pedunculated, and alternately branched; and
the other two are short and divided at their tips. They are
all of a pale-yellow colour, very pellucid, and are about a
fifth of the length of the body when it is fully extended.
The two short tentacles correspond to the two tuberculated
rows of feet of the dorsal aspect.
The body of the animal is covered with calcareous pilates
of an irregular form, perforated by nearly circular apertures
(fig. 4). The plates found in the feet of the three ventral
rows (fig. 7) are spindle-shaped ; but they change their form
in the feet immediately surrounding the head (fig. 8), and
become in appearance very similar to the plates found on
the body-skin. ‘The plates of the dorsal tubercles and feet
(fig. 3) resemble in their irregularity the plates of the body
of the animal; and the same may be said of the plates occur-
ring in the tentacles (fig. 6), in which they may be found
extending to their ultimate divisions.
The very delicate structure of the feet enabled me to
examine them microscopically in the living animal; and
when so examined, a continuous circulation of a minutely
granular fluid may be seen, the current consisting of two _
streams—one passing along one side of the foot to the suck-
ing-disk, and the other flowing back from this structure to
the body of the animal.
This little creature evidently belongs to Linneus’s genus
Holothuria, which Van der Hoeven has lately revived with
the following signification: —
334 Proceedings of the Royal Physical Society.
“Feet of twofold structure and figure, some cylindrical,
dilated at the tip, usually occurring in the abdomen only,
others situated on the back, not dilated at the tip, emerging
from warts on the back. Body cylindrical or flattened in
the abdomen.”
Having only found one specimen of this Holothuria, it
would be premature, it appears to me, to describe it as a new
species. ;

III. Notes on the Ornithology of Caithness, By R. I, Suearer, Esgq.,
Ulbster House, and H. Osgporne, Esq., Wick. Communicated by
Joun ALEXANDER SmitH, M.D.
Part I.—By R. I. Suearer, Esq., Wick.
I have been induced to gather together a full and authentic
list of all the birds hitherto found in Caithness, the main
aim being to induce others to exert themselves in this de-
hghtful and interesting study ; and 1am confident that, had
the ornithology of the county been understood and attended
to by a greater number of persons, a much larger list could
have been made. The all-sufficient reason I have for think-
ing so is, that the present lst only exhibits twelve additional
species within the last twenty years! In particular, that
portion of the interesting and numerous family, the Syl-
viadee, comprehending the Warblers proper, is almost utterly
unknown—the only representatives known to us being the
reed and wood warblers. This paucity, however, must not
in any degree be considered as indicative of their absence
from the county, but must, on the contrary, be ascribed to
the fact that their haunts are far removed from, and, indeed,
are forbidden ground to, the ordinary investigator and those
interested in their economy. Although the northernmost

county in Scotland, and separated from the “ storm-swept
Orcades” by only the narrow belt of the Pentland, through-
out the summer the few wooded tracts scattered over it re-
sound with the melody of divers species of this delicate and
lovely family. A wide and untrodden field lies here before
the first intelligent student of nature who may be privileged
to follow and observe these summer visitants in their sylvan
seclusion. The plantations of Stirkoke, the woods surround-
ing Hempriggs House, and that paradise to the sportsman
and naturalist the valleys of Berriedale and Langweil, are
favourite and much-frequented resorts.
Previously to 1840, Dr Sinclair of Wick had collected
and prepared with his own hands all those in the fol-
lowing list unmarked by an asterisk, amounting to the
truly surprismg number of 191; therefore it will appear
that to the Doctor those interested in the subject are
deeply indebted. Another reason for making this list 1s,
that almost every other county has already a published
register of its birds; and the rich and varied catalogue which
this county can present can be surpassed by but few within
the three kingdoms. Our diversified list exhibits species
that can hardly be exceeded in richness of colouring by the
gaudy inhabitants of tropical countries, such as the gar-
rulous roller ; natives of the warmer parts of Asia and Africa,
such as the spotted flycatcher and the rose-coloured pastor ;
and, contrasted with these, those splendid strangers from
the frozen regions of the Arctic circle, the snowy owl, the
jer-falcon, and the ivory and Iceland gulls. As instancing
what has been done in the way of illustrating the ornitho-
logy of this northern locality, I may in particular mention,
although these are not the only works of a similar kind, the
“Fauna Orcadensis” of the Rev. G. Low; the ‘ Natural
History of Orkney,’ by Messrs Baikie and Heddle; the
“ Tour in Sutherlandshire,” by the late Mr St John; and the
catalogue published in the ‘ Zoologist,” by that enthusiastic
naturalist, Mr Thomas Edward of Banff. I also cannot omit
noticing some of the very rare and valuable birds which Dr
Sinclair has been fortunate enough to secure within the
bounds of the county, although I regret not being able to
VOL. II. 2x
336 Proceedings of the Loyal Physical Soctety.
give the details and date of the capture of many of them. —
Of these, by far the most interesting is the little bustard,
very few specimens of which have been obtained even in
England, where the only authentic instances of its capture
in Britain have been recorded. Montagu’s harrier, a species
but lately discriminated from the common harrier, is a rare
bird in the southern division of the kingdom, where its
peculiarities and appearance first attracted the attention of
the observant naturalist whose name it bears. The stock-
dove, the ortolan bunting, the reed warbler, and the poma-
rine skua, although not exactly rare in the southern counties
of England, have never, according to Mr Selby, been dis-
covered by him north of the Tweed. Baillon’s crake, the
red-breasted goose, the ruddy sheldrake, and the hooded
merganser, are among the very rarest British visitants, only
one or two individuals of each species having been obtained,
as recorded by the same authority in his “ Illustrations.”
The additions made since 1840, distinguished by an asterisk,
demand a passing remark. In the first order, the jer-falcon
is added on the authority of the Rev. F. O. Morris, who re-
lates in his “ British Birds” that one was observed near
Thurso, by W. M. HE. Milner, Esq., M.-P. The snowy owl
has lately been pretty frequently found. The first notice
of it was given by Dr Sinclair, who possesses three indi-
viduals, one of which, a mature bird, is perhaps the finest
specimen in any collection in Britain. In the second order,
the parrot crossbill was obtained by Mr G. Auld of Wick
from some fishermen, in whose boat it alighted whilst at
sea, and was kept in confinement for a considerable time.
A single specimen of the lesser spotted woodpecker has been
found by Dr Sinclair. The wryneck has been twice ob-
tained, once by the gentleman mentioned above and once
by myself. The European roller I saw at Ulbster in 1857.
In the third order, Dr Sinclair has added the little bustard,
which, considering how few are the species of the family
Struthionide found in Britain, is a particularly interesting
addition. In the fourth order, I have found the common
godwit. In this order Dr Sinclair has included the dotterel
(Charadrius morinellus), a very rare bird ; while, undoubt-

edly through inadvertence, he does not mention the ring dot-
terel (C. hiaticula), which is as common as the other is rare.
In the fifth and last order three new species have been
, added—the bridled guillemot, found in abundance on our
east coast every year, Richardson’s skua, and an Ivory gull,
found by myself. This bird is stated, on the authority of a
celebrated Scottish naturalist, not to belong to the common
species, but one new to the British list. I have not, as yet,
ascertained its name.

been done either in the way of discovering or discrimi-
nating new species. Of the three last added, the chiff-
chait (Sylvia hippolais) was shot at Ulbster, in July,
by Mr R. I. Shearer, who subsequently procured another
specimen. A fine male blackcap warbler (Curruca atri-
capilla) was shot by myself on the 16th October, and a
female of the same species on the 28th (the birds were ex-
hibited). Besides the fact of these birds being new to the
Far North, the dates are so late that it has been matter of
surprise to all who have heard of the circumstance, and
know something of the economy of the bird, how such a
delicate member of the family of Sylviade could possibly
subsist at such a season in this climate. With the excep-
tion, however, that the male was not in song, both birds
were as active and lively as they are described to be in mid-
summer, and both, too, were in perfect plumage. I have
observed, in cases where the swallow has prolonged its stay
with us until far on in the season, that there was an evident
lack of that liveliness, vigour, and power of flight, displayed,
for instance, in the month of June; but no such peculiarity
was observable in the blackcaps. This, for the most part,
perhaps, may be owing to the fact that the blackcap, when
insect food is scarce, can subsist on the smaller fruits, while
the swallow is wholly insectivorous. While under my own
observation, the blackcaps fed principally on the berries of
the mountain-ash. The Naturalist-Hditor of “‘ The Field”
newspaper, in commenting upon the occurrence of the
blackcap in Caithness, truly remarks :—‘“ In the statement
that the blackcap eats rowans, in Cacthness, in the middle of
October, we have therefore three novel facts in natural
history, instead of one.” The third and last addition was the
cole tit (Parus ater), shot in a narrow belt of plantation
about a mile from Wick. Mr Sandison, who shot this
specimen, also procured another, some days after, from the
country. This beautiful bird, although common in most
Scottish counties, has not hitherto been recorded as occurring
in Caithness. In addition to these, a crossbill, which some
authorities have pronounced to be Lowxia pityopsitiacus (the |
bird was exhibited) was found dead in the neighbourhood of —

some woods near Lyth; but this species, as may be seen by
the catalogue, has occurred once before, some fishermen
having caught a male which alighted in their boat at sea.
In reference to the nesting of our birds, I am not aware
that we possess anything either novel or peculiar; but a few
random observations may not be altogether without interest.
The most striking example of gregarious nidification the
county can show, is exhibited on an island in the Loch of
Stemster, where some thousands of the black-headed or
laughing-oull (Larus ridibundus) congregate in spring. The
egos deposited on one-half of the island only are taken in
the season, and these are lifted at short intervals, the numbers
taken on some occasions being almost fabulous. They are
valued as an edible of great delicacy. Round the edge of
this island, among the rushes and other covert, several species
build and rear their young. The nest of the mallard (Anas
boschas), the eggs invariably concealed beneath the downy
mass which the female plucks from her breast, is frequently
met with, varied now and again by the massive and some-
times floating structure of the coot (Fulica atra). It is
almost certain, also, that the tufted pochard (Fuligula
cristata) breeds in the vicinity, as specimens are observed
constantly throughout the summer months. In Mr Selby’s
time, this pochard was not known to breed in Britain, but
the later work of Morris contains several instances.
The Arctic tern (Sterna Arctica) breeds, among other
places, ina piece of moorland in the vicinity of a loch about
four miles from Wick. In the breeding season this tern
may be observed following the course of the river in its
flight to and from its feeding-grounds, which are at the
mouth of the river and round the bay. During its journey
I have observed it occasionally, but not often, stop suddenly
in its flight above the river, apparently attracted by some
small fish, remain suspended, like the kestrel, for an instant,
and then drop headlong upon the object that had attracted
its attention. It is in the bay, however, where this bird
chiefly finds subsistence ; and here the habits of this tern,
and of several species of gulls, may be observed under the
most favourable circumstances. The principal prey of the
VOL, I, Au
344 Proceedings of the Royal Physical Society.
Arctic tern appears to be the sand-eel or sand-lance (Ammo-
dytes). ‘This rather curious fish appears in our bay occa-
sionally in prodigious shoals; indeed, one of our most
observant fishermen lately informed me that the masses of
these fish he has seen on our coast exceeded by far anything
of the kind he ever saw, not excepting the “races” or
‘‘banks” of herrings, which are described (principally by
sanguine ship-captains) as being something prodigious.
Large numbers of sand-eels are exhumed from a sandbank
at the mouth of the river. They are used as bait, and
numerous fishermen visit the bank when the tide has ebbed,
armed with an instrument resembling a corn-hook, with
which they dexterously drag to light the buried eel. I
witnessed a foray of this description in spring last; but
although this was not the first occasion, I was attracted in
this instance by the number of sea-fowl that fluttered over
the fishermen’s heads, and came almost within reach of the
weapons in their hands. The Arctic tern, the lesser black-
backed gull, and the kittiwake were the species that jomed
in the pursuit. The kittiwakes were the boldest, or rather
the most familiar, of the three; and at a distance, you could
hardly say with certainty whether the eel just brought to
light was destined to find the fisherman’s basket or the
kittiwake’s maw. It was almost a neck and neck race, and
Piscator very frequently had not much to spare.
That large and splendid species, the great black-backed
gull, breeds on favourable stations all along our east coast.
What appears to be favourite situations are those insulated
rocks to which there is no access by land. On the flat and
grassy tops of these gigantic pillars, the black-back builds
and rears its progeny, which resemble the young of the her-
ring and other gulls. Sometimes such a “stack,” as these
pillars are termed, is occupied by two or three pairs; in
other instances a single couple hold undisputed sway, and
monopolise the isolated territory. When the haunt of these
gulls is intruded upon, the whole colony rise screaming over-
head, making a terrific din; but above all the uproar, the
hoarse croak of the “ Saddle-back” may be distinguished.
The lesser black-backed and herring gulls occasionally

sweep within reach, but their larger associate keeps far
above, and seldom ventures within gunshot. On one of
these ‘‘ stacks,” situated in Sinclair’s Bay, I have seen shags
and cormorants sunning themselves in every niche, the top
even being occupied by numbers of these sombre gentry.
The black-back is extremely wild and vigilant, and conse-
quently difficult to approach ; the only time when it ventures
within reach of a gun, being in the breeding season, when
it usually becomes a degree bolder. This gull is also very
jealous of the neighbourhood of hawks and crows, having in
especial an antipathy to the hooded crow. From its size
and fierceness, it is generally monarch of all it surveys, the
raven even succumbing to its attacks. In the last breeding
season, however, the district received a visit from a stranger
before whom all birds fled, the great black-back even making
discretion the better part of valour. This was a white-tailed
or sea eagle (Halietus albicilla), and his presence evidently
caused the more alarm, from the fact that an eagle is seldom
or never seen in the vicinity. An observer who carefully
watched this powerful depredator while beating the margin
of a loch not far from the edge of the rock, saw him slip
over the precipice and shoot along about half-way between
the top of the cliff and the sea. Hardly had he made his
appearance, when a rush of birds seawards took place.
Hverything that could fly left the rocks, and the terror and
confusion that ensued was remarkable. This continued
during the whole course of his flight, and his appearance
was invariably the signal for a hurrying of the scared masses
out of the reach of danger. So numerous, and so very much
frightened were the birds, that the progress of the eagle
could be traced, long after he himself was invisible, by the
strings of seafowl, of various kinds, that persistently con-
tinued to seek safety in flight. It was long before gull and
guillemot got over their fright, and matters resumed “ the
even tenor of their way.”
The Arctic skua, the lesser black-backed gull, and the
common gull, breed in a remote moorland district in the
centre of the county. Here there are numerous pools or
patches of water, known as “ doo-lochs,” of various sizes
and shapes, studded with mossy mounds or islands, which
346 Proceedings of the Royal Physical Society.
are usually as high above the surface as the surrounding
ground. On these mounds the birds, for the most part, rear
their young with safety. Great numbers of eggs are de-
stroyed, however, as, in consequence of there not being space
enough on the detached portions for the multitude of birds
that resort hither in the season, numbers of nests are built
on the margins of the pools, which are robbed by herd-
boys and occasional visitors. I have seen some excellent
specimens of the Arctic skua shot in the neighbourhood of
these lochs in spring last by a collector. The lesser black-
backed gull does not restrict itself apparently in the choice
of a situation for breeding, as its nest may be found in-
land on these moors, as well as on the “ stacks” frequented
by the great black-backed and herring gulls. In the inland
district above-mentioned, the curlew breeds regularly, and
I have good reason to believe that it also forms a breeding-
station of the whimbrel (Numenius phwopus). The nest of
the kestrel may frequently be met with along the east coast.
A few pairs of peregrines still manage to rear a brood here
and there amidst the precipitous rocks, but this bird exists
in greatly diminished numbers. The sparrow-hawk is much
rarer with us than the two species above-mentioned, or than
the hen-harrier or merlin. The hen-harrier is known to
breed in a retired hilly district about twenty miles from Wick.
The merlin, the smallest and most beautiful of our falcons,
builds its nest among the heather, usually selecting a situa-
tion where the growth is luxuriant and abundant. On one
occasion, some years ago, I accompanied a gamekeeper and
his two sons on an expedition to the hills of Yarrows, dis-
tant about seven miles from Wick. The object of the expe-
dition was the destruction of a couple of merlins, which had
built their nest amidst the heather on a gentle slope, which
ran backward from a narrow valley or ravine. It was anti-
cipated that, by keeping this hollow until opposite the nest,
both birds might perchance be secured in its neighbourhood.
The desired point was reached, the guns (three) were pre-
pared, and the trio were just on the point of leaving their
hiding-place, when the shriek of the male bird, giving the
alarm, was heard, and on looking up the little fellow was _
descried far overhead, sailing in circles, and anxiously watch-

ing every movement. Not a moment was to be lost, and
the three, ranged in line, left their hiding-place and ad-
vanced rapidly on the nest. If the female still remains,
her chance of ezcape is a poor one, for she is now within
range of six barrels! She sits so close, however, that doubts
are beginning to arise, when up she springs and dashes
rapidly off, brushing the heather in her flight. She has not
flown far when a single shot is fired, and poor falco drops
among the heath with a broken wing. The male escaped
on this occasion and was not seen again, although diligent
search was made for some days afterwards. The nest con-
tained four eggs, and was situated where one would rather
expect to find the nest of the red grouse.
Dr J. A. Smith said, naturalists were indebted to Mr
Shearer and Mr Osborne for their valuable list, with its
accompanying details, of the birds of Caithness. He had
requested Mr Osborne to add some notes on the nesting of
the birds, and was sure the Society would agree with him
in the great interest of these communications; he only
wished a similar careful list of the appearance and nesting
of the birds, could be got from all the counties of Scotland.
The capture of the ivory gull, referred to by Mr Shearer as
new (page 341), had been brought under the notice of the
Society by Sir W. Jardine (see Proc., vol. i. p. 4; and vol. ii.
p- 07). The specimen was described by him as being the
Pagophila brachytarsus (Halboll), and the first time it had
been observed as occurring in this country.

by Joun Cotpstream, M.D.
After some introductory remarks on the occasion of his
occupancy of the chair for the first time since his re-election
as one of the Presidents of the Society, Dr Coldstream ad-
verted to the great loss which the Society had recently
sustained in the death of Mr John 8. Livingston, one of the
Exhibition of Drawings by Native Artists in India. 349
office-bearers,—a young naturalist whose talents and ex-
tensive acquirements had given promise of much usefulness.
Dr Coldstream said, that long and intimate acquaintance-
ship with the deceased enabled him to bear testimony to the
thoroughness of his habits as a student; to his carefulness
in research; to his probity and moral worth. Of his
capacity for acute generalisation, the Society had been
favoured with a striking proof in the able paper ‘‘On the
State of our Knowledge respecting Metamorphism in the
Mineral Kingdom,” which he read in March last. This,
along with a memoir on the effects of anesthetics on plants,
made Mr Livingston’s talents widely known, and led him
into extensive correspondence with men of science. His
modesty and courtesy of manner were as remarkable as his
acquirements, and endeared him to a large circle of attached
friends. Dr Coldstream then submitted for the inspection
of the members a large collection of drawings in water
colours, of various Indian animals, chiefly insects, which had
been made at the instance of Walter Elliot, Hsq., lately a
member of the Supreme Council of Madras. These remark-
ably beautiful drawings were executed by native artists,
under the eye of Mr Elliot. The accuracy and elegance of
the drawings were much admired, and a hope was expressed
that many other residents in India would avail themselves,
as Mr Elliot had so successfully done, of the talents of the
natives, to extend our knowledge of the beautiful produc-
tions of our eastern empire.

Atractylis miniata. 3. Laomedia decipiens. By T. Srrerniun
Wricut, M.D. (Plate XV.)
1. Atractylis arenosa.
This zoophyte was described by Mr Alder at the last
meeting of the Society. In September last I found a large
female specimen at Largo, and was fortunate enough to
have an opportunity of studying its anatomy and repro-
duction. The polyp-stems are, as Mr Alder has shown,
funnel-shaped and expanding at the top. From them the
milk-white polyps issue, each furnished with an alternat-
ing row of long tentacles. The scleroderm, or corallum, is
390 Proceedings of the Loyal Physical Society.
covered by a thick layer of colletoderm, which is con-
tinued over the body of the polyp, and which, when the
polyp retires within its tube, fills up the top of the
tube by its cushiony folds, so that the polyp is completely
hidden, and the funnel appears as it were closed by a valve.
The colletoderm in my specimen was coated and impreg-
nated with mud. Mr Alder’s specimen was covered with
grains of fine sand. I was at first inclined to believe that
this zoophyte was merely a variety of Atractylis repens,
which, with its medusoids, I have already described to the
Society ; but after it had been in captivity a few days, I
found that it was beginning to put forth ovisacs, one on
opposite sides of the polyp-stems (Plate XV. fig. 7).
The mode of reproduction in this zoophyte is unique
amongst the Tubulariade, though I have noticed and de-
scribed it in the Sertularias and Campanularias.
The female generative sac of Atractylis arenosaresembles
that of Hydractinia ; it is a simple sac formed of ectoderm,
or the outer layer of the ccenosarc, enclosing a similar sac
of endoderm, the “ placenta,” the whole being covered by a
layer of scleroderm and colletoderm. Between the placenta
and the ectoderm a large number of ova are developed, each
showing a germinal vesicle and spot (fig. 8). When the ova
are sufficiently advanced for extrusion from{the generative
cavity, the investments of the sac are ruptured, the sac
assumes a long, cylindrical form (fig. 9), and a most labo-
rious process of parturition commences. With each pain
the ectoderm of the sac contracts laterally, like the bell of
a Medusa, and at the same time the placenta (fig. 9 c) is
dilated by fluid pumped into it from the somatic cavity of
the zoophyte, so that the ova, which are floating in a milky
fluid, are forced against the summit of the generative sac.
Meanwhile, another process has been going on,—the ex-
ternal surface of the summit of the sac has been secreting a
thick cap of gelatinous colletoderm (fig. 9 d), which is to ~
form a nidus for the further development of the ova. The
contractions become still more violent, until the ova are
confined in a mass at the dilated upper part of the sac; this
last is ruptured, and they are forced into the gelatinous cap,

which still remains attached to the summit of the empty
generative sac (fig. 10d). The ova now undergo fissure,
and are developed into planule within their nest, then at
last escape, and, after swimming in the water, doubtless
become fixed and converted into polyps.
Atractylis arenosa, although it gives off an immense num-
ber of young, is one of the rarest zoophytes on our coast,
probably on account of the low viability of its planule.
While Sertularia pumila, one of the commonest species, and
which produces its young in the same way, will quickly hne
the vessel in which it is kept with forests of young zoo-
phytes, not a single planula of Atractylis arenosa, of the
immense number that were given off by my specimen, ever
attained the polyp stage.
We have in this zoophyte the reappearance amongst the
Tubulariade of a mode of gelatinous nidification, which ob-
tains in various orders of the animal kingdom,—in the Pro-
tozoa, the Mollusca, the Annelide, the Insecta, and even
amongst the Vertebrata, as in the common frog. We may
ask, How is it that the ova of Hydractinia and Coryne are
discharged into the water to float about without any pro-
tection, while those of Atractylis arenosa, the Sertularias and
Laomedias, require such various provisions for their protec-
tion ? but we do not find anything in the physiology of the
zoophyte to answer the question.

This zoophyte was found on stones at Largo, in little

gaudy colour of the minute polyps. These appear to be
marked by two broad internal patches: one, correspond-
ing to the buccal cavity, of a dense silvery white ; the other

I have also found very minute specimens of this species at
Granton ,
3. Laomedea decipiens. (New Species.)
Polypary minute; stem filiform flexuose, with from one
to five branches, each bearing a cell; the stem is annu-
lated with about five rings above the origin of each
branch; the branches are annulated throughout; cells
widening rapidly towards the top, with even double
rims. Polyp, with about sixteen tentacles and trumpet-
shaped proboscis.
This pretty little Laomedea resembles much the Laomedea
neglecta of Alder, except that the margin of the cell is even,
and has the appearance of being double for about half its
length from the rim, though, from the extreme delicacy of
the cell, this character is only made out with difficulty.
The reproduction of this zoophyte resembles exactly that of
Laomedea lacerata, except that each gelatinous nest of A.
decipiens contains only three ova, while that of L. lacerata
contains six or eight.

III. On the Geological Age of the Pagan Monuments of the Outer
Hebrides. By Captain F. W. L. Tuomas, R.N.
Some recent observations made upon the geological changes
that have taken place since the so-called Druidical circles
were erected in the Long Island, will, it is presumed, be inter-
esting to the Society; although any conclusions from these
observations can only be valued as first approximations to a
knowledge of the era of the unknown founders of these gigan-
tic monolithic structures.
It forms no part of the present subject to describe these
monuments farther than to state, that, as in the Orkneys, in
one locality of the Lewis several of these circles are placed
On the Pagan Monuments of the Outer Hebrides. 353
within a short distance of each other; but no peculiarity is
observable in the selection of their position ; and, from all that
is known at the present time, their place of site appears to be
accidental, or at least chosen without any distinct motive.
One of these circles, the far-famed stones of Callernish, occu-
pies the flat of a ridge of hilly ground, while two others are
near together on a wet and boggy moor, at the distance of a
mile to the eastward of the first. If the circles situated on
the moor had been visited two or three years ago, nothing but
afew gray blocks even with, or protruding two or three feet
above the bog, would have been seen, and even many of the
stones of the large circle of Callernish were completely grown
over and buried in peat. By the liberality of Sir J. Matheson
these three circles have been excavated, and it was then found
that the peat had accumulated to the height of between five
and six feet. From an attentive examination of the founda-
tion of these circles, I arrive at the conclusion that the stones
were pitched before the growth of peat had commenced, or at
least at the very commencement of the peat-forming epoch.
The upright stones are founded in the (so called) boulder-clay
which overspreads this, with most other parts of Scotland, and
the peat rises uniformly from the clay to the surface, which
would not be the fact if holes had been dug in the peat to
receive the stones. Besides, some stones that had early fallen
(in the smaller circles) rest upon the clay without any peat
below them ; and still further, in two of these circles are loose
heaps of stones,—“ cairns,” as they are called, the grave-mounds
of the illustrious dead,—which also rest upon the clay, without
any intermediate floor of turf. If any peat had grown, it
would be found beneath these cairns, for I consider it childish
to suppose that it would have been cleared away. At the
excavation of a tumulus at Stennes, in the Orkneys, which
was presumed to be of or about the same age as the adjacent
stone circles, the heath and moss on which the materials of
the tumulus had been heaped were found in as good preserva-
tion as when the mound was made,
Besides the circles named, there are others, both in Lewis
and Uist, which are only discovered by an occasional stone
peering above the surface; and I see no reason to doubt that

some of these Pagan monuments are entirely buried and out
of sight.
I produce a stereoscopic photograph of the Callernish circle,
which fortunately shows, by a difference in the depths of shade,
the height to which the peat had grown around the stones;
two of them, to the left hand, were entirely covered.
If, then, it is admitted that the stone circles of the Lewis
were placed before, or only when the peat began to form, and
that the peat has grown five feet since that time, it is evident
that the least age of these monuments would be known if the
annual increase of peat was known. But I am unacquainted
with any data from which to form an estimate, and there is a
wide difference in the opinions held on that point. One prac-
tical gentleman assured me that the Lewis peat grew an inch
every year; at this rate the entire deposit might have taken
place in about sixty years. Another estimate is nine inches
in a century, but we require twice the number of years that
this ratio would give to get back to Pagan times. As I am
unacquainted with any class of facts that bears upon the sub-
ject, it is not worth while to offer any conjecture at the present
time. I may mention, however, that to my surprise, one of
the Lewis bards has a tradition that at one time there was no
peat in Lewis ; and it is also to be noted, that almost always, on
excavating any of the Pictish dwellings, pieces of burnt stick
(charcoal) are found at the fire-hearth. I do not wish it to be
inferred, however, that there was no peat to be then found—
only that sticks formed part, if not all, of the fuel then in use.
A most instructive section was made a few years ago on the
banks of the Creed, in the policies around Stornoway Castle.
My notes are mislaid, but if my memory is correct, a cutting
was made through a peat-bank to form a road, by which a
perpendicular section of between eight and nine feet in height
was exposed. About the middle of the bank, that is, three
or four feet below the surface, was and is the place where a
fire had been kindled; a few stones had been put round on which ~
to stand the kettle, probably to boil a salmon, and bits of char-
coal still remain in the ashes. The banks of the Creed could
still supply enough indigenous birch to boil a craggan.
Very erroneous opinions are abroad concerning the cause
On the Pagan Monuments of the Outer Hebrides. 355
and growth of peat ; in most books I see the observations of a
certain Lord Cromarty are quoted, from which it is most illo-
gically inferred that all peat is the result of the decay of forest
trees. So wide spread is this allusion, that it has been quoted
to me where the peat-banks were visibly and presently telling
their own history. Without denying that the decay of forest
trees in marshy ground will form peat, it requires only the
most superficial observation to know that wood peat occurs
only in the most homeopathic quantity in, at any rate, the
islands of North Britain. It fortunately does occur as an
exceptional instance, and then in so marked a manner as to
leave no chance of confounding wood peat with the almost
universal moor peat. The bulk of the peat of the northern
and western islands is made up of the roots of rushes and
moor-grass; the mosses help to keep it constantly wet, and
the tormentilla (and probably other plants) supplies tan to the
moss, and prevents it from decomposing into vegetable earth.
Such were the conditions when the peat first began to grow,
and such they still continue. I have looked over thousands
of sections of peat banks in which there was no difference in
the composition of the peat, from the base where grew the first
peat-forming plants to the surface at the present moment,
excepting consolidation towards the bottom from time and
pressure. When the surface of a peat bank has been exposed
for some time to wind and rain, the most solid, as well as the
spongier portions of the peat will be found disintegrating into
laminze, which lamine probably represent the annual growth,
and if they were distinct enough to be counted would indicate
the age of the peat. Irom whatever cause, there was a time
when the general surface of the country was bare and lifeless,
which was followed by a growth of plants, in no way differing
from those that are now struggling for existence upon the
moor. And from what has been said before, it would seem
that man made his advent here at much about the same
geologic time.
A common tradition of the Lewis is, that the ground was
once entirely covered with forest trees, and that the wood was
burnt down by the Northmen to deprive the aborigines of the
shelter that it afforded. In almost all traditions there is
356 . Proceedings of the Royal Physical Society.
some relation to fact; but without going into the history of
this opinion, it will be enough to notice, that as far as I am
aware there is but one place in Lewis where the remains of
forest trees are to be found. ‘The roots of firs over twelve
inches in diameter occur near Balaline, in the parish of Lochs,
and only there. These roots are always on the clay soil, for
neither bush nor tree is found with its roots in the peat.
But although in a thousand cases the section of a peat bank,
from its surface to its base, exhibits only a succession of marsh
plants, a patient observer will here and there find a spot
where the foundation of the peat is a floor of twigs and leaves.
This, as stated before, bears only a minute proportion to the
moor peat of the country. When examined it appears to be
made up in great part of the twigs of the birch, but I have no
doubt that the berry and bush of the mountain ash, the larch,
the aspen, and the willow could be detected. In fact, it so
happens that in this strange country, where many of the
manners of the tenth century still exist, the method by which
this peat of scrub and brushwood was formed can still be
seen. On the small islets in the lakes, to which neither
sheep nor cattle can gain access, a dense mass of scrub still
survives. The heather will grow four feet in height, and
above that may be seen the red berries of the mountain ash, or,
if in spring, the catkins of the willow, or the pendant leaves
of the aspen, with briers and brambles to interlace the whole.
In the face of some cliffs and banks, and even in a few re-
mote spots, the holly, hazel, aspen, birch, and willow, still
struggle against an adverse climate as they did a thousand
years ago.
I have been thus particular in pointing out the limited
quantity of wood peat, and where it occurs, its position, rest-
ing upon the boulder clay, for a purpose to be more particu-
larly described at the close of this paper; and I pass on to
notice some important geological changes that have taken
place in the most recent or peat-forming era.
My official duties led me last summer over several hundred
miles of the most tortuous coast-line imaginable. Between
North and South Uist lies the large island of Benbecula, and
about five hundred others of different sizes and shapes; most

of these can be approached on foot at low water, and the rest
are only separated by shallow channels. On going round the
coast I began to notice that the peat banks formed frequently
the sea-margin at high water; and feeling that it was a point
of some geological importance, I noted the places on my sketch
of the coast, till at last finding that the phenomenon was ex-
tremely common, occurring perhaps twenty times in a day’s
walk, it was no longer necessary to record its occurrence.
After examining hundreds of examples, I came to the conclu-
sion that, in these instances, there was no other way of
accounting for peat banks having that position with regard to
the sea-margin, than by the subsidence of the land. In many
of the cases referred to, the peat rests at once upon the naked
gneiss. Now, the surface of the gneiss is as rugged as, and
not very unlike what, the surface of the ocean would be if it
were suddenly solidified in the middle of a violent storm. The
peat has grown over the undulatory surface, but, as was to be
expected, is deepest in the depressions, where I have sometimes
seen it in section more than ten feet in height. Let it be sup-
posed that the relative levels of land and sea remained the same
until the formation of peat had occurred, and then that the
land began to subside. The effect would be that when the sea
reached the foot of the peat banks small cliffs would form,
identical in their features with those of clay or gravel, or any
other soft material. But from the extreme softness of the peat
the sea would quickly eat it away, and work itself into all the
sinuosities of the surface gnciss that were below the level of
high water. This is what has happened around Benbecula ;
the sea at high water flowing in amongst the knolls, at first
forming a simple gap, then branching out like the arms of a
tree; at a further stage in the destruction of the peat, a group
of islands is formed, till at last the whole vegetable soil is
washed away, and a few bare rocks serve to point out where but
one generation ago the cattle have pastured and corn has
grown. Some of these rocks, which are now completely bare,
still bear the names of particular plants that once grew upon
them. It is difficult in words to convey an idea of the
appearances and of the facts; but an inspection of the coast
would show that the peat could only have been brought into
358 Proceedings of the Royal Physical Society.
its present position by the subsidence of the land. There are,
indeed, but two other ways by which the peat can be found to
form the sea-coast; one is by the action of the sea upon the
shore, the other by the peat advancing to the sea by slip. But
neither of these cases will apply to the sea threading in among
the knolls and hillocks, eating out holes at first, which become
pools, then lagunes, till at last the land that enclosed them is
all gone. It must therefore be accepted asa fact, that the
land has subsided (and is subsiding) since the peat began to
form, and, consequently, that the stone circles of the Lewis are
of an age anterior to that subsidence ; it follows, then, that if
the rate and quantity of subsidence were known, and supposing
it to be uniform, we should arrive at the least age of the Pagan
monuments.
Although we cannot arrive at the whole quantity, we have
fortunately a measure of a part of that subsidence ; this is
afforded by what have foolishly been called submarine forests,
but which are in fact submerged peat-banks.
In the Orkneys I have noted six places at which submarine
peat is said to be found; at Otterswick, in Sanda, I have seen
the people digging 1t at low water for fuel. The peat was
mainly composed of twigs and leaves, and the seeds of the
birch were plentifully scattered through it. There were also
many gnarled pieces of wood, of the thickness of a man’s arm.
I was informed, on describing the kind of peat found at Otters-
wick, that the same sort of fuel may be got at Balranald, on
the west of North Uist, at the level of low water. Peat also
occurs below mud and gravel between tidemarks at the head
of West Loch, Tarbert, in Harris; and Martin, the historian
of the Hebrides, speaking of Pabbay, an island in the Sound
of Harris, says, ‘‘ The west end of this island, which looks to
St Kilda, is called the Wooden Harbour, because the sands, at
low water, discover several trees that have formerly grown
there. Sir Norman Macleod told me that he had seen a tree
cut there, which was afterwards made into a harrow.” Se-—
veral traditions could be added, of places now submerged
that were formerly the sites of chapels or houses; and I think
it may be taken as proved, that since the commencement of
the peat-forming era, the land has sunk or subsided twelve

feet at least ; how much more, there are no means of finding
out, for the submarine peat may have grown near to, or far
away from, the high-water level; neither do we know how far
the submerged peat-banks extend beyond the level of low water.
From the foregoing facts, it may be inferred that very soon
after the climate of the Hebrides became such as to admit of
the growth of vegetation, man emigrated te these shores,
bringing with him the arts of agriculture and navigation, and
a religion that induced him to honour the memory of his
illustrious dead. Since then the tanned vegetable mould has
accumulated to the height of at least five feet, and also since
man’s advent here the entire land has sunk twelve feet or
more. These data may, by a more extended investigation,
form a measure to the time of his arrival; at present I must
content myself with having pointed out the facts.
IV. Description of several Fishes from Old Calabar. By Joun CLeLann,
M.D., Glasgow. Communicated by Wittiam Turner, M.B.
The specimens now exhibited were given me by our late lamented
Treasurer, Mr Oliphant, and it was his desire that they should be shown
to this Society. They come from Old Calabar. They are not in very
good preservation, but are sufficiently so for the determination of their
characters. Besides a small specimen of Chromis niloticus (Cuv.), there
is an Hleotris and four fishes of the family Silwrozdez, none of which cor-
respond with species described in the work of Cuvier and Valenciennes,
or such other books as I have been able to consult. They may possibly be
mentioned in recent monographs which I have not had an opportunity of
seeing.
1. The Eleotris presents well the characters of that genus, the head
being much depressed, the body slender, the eyes remote, the gape very
large for the size of the body, and the lower jaw prolonged beyond the
upper, so as to give the mouth an upward direction, which may probably
be looked on as convenient to a fish inhabiting the muddy parts of the
water, and preying upon animals swimming overhead. Also, it shows
well the appendage behind the vent and the ununited ventral fins, which
distinguish this genus from Gobius. It has no vomerine teeth ; its scales
are small; its total length to the tip of the caudal fin is five inches. The
caudal fin is one inch long and rounded.
The number of the fin rays is as follows :—first dorsal eight, second
dorsal ten, caudal thirty-two, anal nine, pectoral sixteen, ventral six.
2. Of the Stlwroed specimens one is a Synodontis, and corresponds
exactly with a specimen in the British Museum. I believe that it is the
Synodontis serratus, although the number of its fin rays agrees rather
with that attributed to S. arabi in the work of Cuvier and Valenciennes.
The anterior dorsal fin has eight rays, the first of which is, as in all
the members of the genus, a long and strong slightly curved spine fixed
at right angles to the body. This spine is toothed on its posterior edge,
and towards the point anteriorly.
The posterior or fatty dorsal fin, half an inch high and two inches long,

360 Proceedings of the Royal Physical Society.
is continued further back than the posterior margin of the anal fin. The
caudal fin is bifurcated, the superior half longer than the inferior.. From
the longest ray above to the longest below, inclusive, there are seventeen
rays; and outside these there are eleven shorter rays in each half.
There are thirteen rays in the anal, nine in the pectoral, and seven in
the ventral fin. The first pectoral fin ray in Synodontis is a large spine
toothed before and behind, the posterior teeth being longest, about equal
in length to the dorsal spine. There is no locking arrangement in its
joint, and therefore it can only be kept in the extended position by mus-
cular effort. On the other hand we find the lock-joint of the pectoral
spine in genera in which the dorsal spine is not fixed, as in this genus.
The superior scute of the head passes back nearly as far as the third
dorsal fin ray. The coracoid scute is triangular, and passes back as far as
the superior scute.
The long curved teeth which hang loosely in the lower lip, and which
give character to the genus, are twenty-four in number. Behind them
are fine velvety teeth, the patches of opposite sides distinct. In the
upper jaw there is a double row of conical teeth, about eighteen on each
side, and behind them (on each side) a patch of setose teeth of very
irregular size.
There is one superior pair of barbules very long and simple, and two
inferior pairs, both of them branched, the outer pair half the length of
the superior pair, and the inner pair half the length of the outer.
The specimen is twelve inches long from mouth to tip of tail, and three
inches from mouth to the first dorsal spine.
A view of the swimming-bladder of Synodontis is given by Miller in
his work on Myxinoid fishes.
3. Two of the specimens exhibited belong to the genus Clarias, which
is characterised by the presence of arborescent branchial appendages
attached to the second and fourth branchial arches, and by having only
one dorsal fin.
The first of them corresponds exactly to one which I have had the
opportunity of examining in the British Museum, and which, therefore,
we may expect to have properly described by Dr Gunther in his elaborate
work, of which part is already published. The specimen is a foot long.
The head is depressed and shielded, oblong in form, the eyes small and
lateral; the body is oblong, compressed. The dorsal fin extends from
within an inch behind the head back to the tail, but is not continuous with
the caudal fin; it contains seventy-six rays, the first of which is not
_ spinous.
The caudal fin contains twenty-four rays, the anal sixty-three, the
pectoral twelve, the ventral six. The first ray of the pectoral fin is a
spine toothed before and behind, and having a lock-joint, that is to say,
its joint is so constructed that when the spine is fully extended it cannot
be pushed back towards the body by any direct pressure, but must first
be rotated to a certain extent, and then it folds back easily. The anal
fin is continued, like the dorsal, back to the caudal, without being con-
tinuous with the latter. There is a papilla behind the anus.
The teeth are velvety, in very broad patches. The teeth in the upper
jaw are larger than those in the lower; the patch in the lower jaw is
broader than that in the upper, and indented at the outer side. On the
vomer there is also a broad patch of very minute teeth.
The barbules are eight in number. The anterior superior pair are
longest, the external inferior pair slightly longer than the posterior
superior pair, while the internal inferior pair are thick, short, and trun-
cated, a character peculiar to this species.

Species, viz., Clarias Nieuhofi and Clarias jagur, in the dorsal and
anal fins being continuous with the caudal. It has only one arborescent
branchial appendage on each side, which is attached to the fourth bran-
chial arch, and is very small. The specimen is eight inches long to the
tip of the caudal fin, the latter being three-fourths of an inch long. The
head is depressed, not shielded, three-fourths of an inch long, the body
compressed. The barbules are eight, the branchiostegal rays nine. The
anterior superior barbules are broadly membranous at the base.
The teeth are velvety, the patch on the lower jaw is much larger than
that on the upper, and there is a patch on the vomer.
The dorsal fin begins an inch behind the head ; it has no spinous first
ray. ‘The rays in it and the anal fin are very numerous. The pectoral
fins are small, and have six rays, the anterior ray being a short spine, less
than half the length of the succeeding rays, and not lock-jointed. The
ventral fins are small and contain three rays.
5. The remaining specimen is a species of Heterobranchus. Hetero-
branchus is a genus allied to Clarias, having the same sort of arborescent
branchial appendages, but having two dorsal fins, the posterior of which
is fatty.
The specimen is five and a half inches long, three-fourths of an inch of
this length belonging to the caudal fin. The appendages will be seen on
the second and fourth branchial arches.
The head is very much depressed, broad, shielded, the eyes lateral, the
barbules eight.
The branchiostegal rays are eight. The first dorsal fin has thirty-five
rays, the first one not spinous, it ends behind the middle of the body.
The fatty dorsal fin extends from the true dorsal to the tail, and contains
traces of eighteen very fine rays. The caudal fin has twenty-two rays ; it
is rounded, and is tipped with black, as are also to a less extent the other
fins, and the dorsal aspect of the head is also black. The anal fin has
forty-seven rays, and extends from anus to tail. The pectoral fin has
ten rays, the anterior ray toothed and lock-jointed, shorter than the suc-
ceeding rays. The ventral fin has six rays.
The teeth are velvety, in elongated narrow patches, one of which is on
the vomer.
V. Note of the Common Squirrel (Sciurus vulgaris) Feeding on Buds
and their Eggs. By Tuomas Duruam Wer of Boghead, Esq., Bath-
gate. Communicated by Dr Jonn ALEX. SMITH.
The far-famed Charles Waterton of Walton Hall, Hsq., near
Wakefield, in his amusing and highly interesting Hssays on
Natural History, has strongly maintained that the squirrel
derives its supplies of food wholly from the vegetable king-
dom, and.is not possessed of any carnivorous propensities.
I shall however prove from a few facts, for
“ Facts are chiels that winna ding,
Wage And canna be disputed,”
that this is not the case, but that some members of this
family are not true vegetarians, and do occasionally indulge
in carnal feasts.
362 Proceedings of the Royal Physical Society.
Hear what Mr Waterton says in reply to a published
account of a tame squirrel eating flesh in confinement :—
“Had the squirrel been wild in the wild woods at the
time that Mr Wigton saw it eat birds, I should not hesitate
to pronounce that individual squirrel to be carnivorous,
because I believe that Mr Wigton would only state what he
conceived to be correct. I gather from Mr Wigton’s com-
munication that his squirrel was in captivity when it
partook of a carnal feast. This single fact at once precludes
the possibility of the Squirrel family being raised to the
rank of carnivorous animals. The incarceration only of a
few days might have injured the prisoner seriously, either
in his nervous system, or in his gastric powers, or in his
olfactory sensibilities."—Now for my facts :—
A few years ago, during the month of May, Mr James
Hunter, a respectable merchant in Bathgate, upon whose
veracity I can place perfect reliance, informed me that
whilst walking through the plantations of Andrew Gillon,
Hsq. of Wallhouse, he observed a squirrel sitting upon the
branch of a tall larch. Being near to the farm-steading of
Broom Park, and anxious to get it for a specimen, he
brought out the son of the farmer, who immediately shot it.
To their astonishment they found a small bird firmly clutched
in its claws, with its skull laid open, and the brains taken
out.
James Bell, another observer, told me that when walking
through a plantation on his father’s farm of Carriber, near
Linlithgow, he observed a squirrel in the act of sucking
egos which were deposited in a bird’s nest, and that when
he approached it scampered off with one of them in its claws.
Mr George Heathe informed me that, in July last, when
resting at his meal hour in a plantation near Bowhill House,
a seat of the Duke of Buccleuch, in the neighbourhood of
Selkirk, his attention was attracted by the lively gambols of
a squirrel among the trees. In the course of its movements
it happened to come upon the nest of a thrush containing
several newly-hatched birds. Seating itself beside the nest,
it took a short but deliberate survey of its contents, and
then lifted one of the birds, which it held between its fore

paws, and proceeded to devour with apparently the greatest
relish. Not contented with this, it was in the act of taking
another from the nest, when the enjoyments of the feast were
broken in upon by the hitherto unseen observer of the
depredation.

This white variety of the common hare was shot near
Lauder about the end of January. The animal was large,
and well fed. The eyes were carefully examined, and were
pink or red, showing the usual deficiency of the dark pig-
ment of the eye, which occurs in albinos. The ears, which
were longer than the head, had no black colour on their
tips; and the upper part of the tail, instead of being black,
as in the common and Alpine hares, was, like all the rest of
the animal, pure white.
VII. Ornithological Notes. By Joun AuexanpEerR Smitn, M.D.
(Specimens exhibited.)
(1.) Turdus Merula (Penn.) Blackbird.—A pied variety
of this bird was exhibited, the head and upper parts of the
body being variegated with numerous pure white feathers.
It was shot on the 3d of February near Dundas Castle, Lin-
lithgowshire.
(2.) Loxia curvirostra (Penn.) Common Crossbill.—A
male and female, in fine plumage, were exhibited, killed on
the 13th January, near Aberdeen.
(3.) Picus Major (Penn.) Pved or Great Spotted Wood-
pecker.—Adult male specimen, showing the crimson red
occiput, was found in May 1861 lying dead in the shrubbery
of T. Durham Weir of Boghead, Esq., near Bathgate, Linlith-
gowshire. The bird seems not to have been before observed
in this county ; it is not included in the list of the birds of
Linlithgowshire, by the Rev. John Duns, recently published
in the Proceedings of the Royal Society. A young male,
shot on the 4th of last December, at Kirkwall, Orkney,
was also exhibited. It is one of our rare local residents,
and is an accidental visitor or straggler in Orkney. An-
other specimen was killed in Orkney in the month of August
364 Proceedings of the Royal Physical Society.
last, and was sent to Mr J. Carfrae, Princes Street, to be
preserved.
(4.) Hybrid Grouse, between Blackcock and Red Grouse.—
Two male, apparently hybrid grouse, in very fine plumage,
were exhibited. ‘They show a resemblance to both parents,
and their size is intermediate between them; being rather
less than that of the male blackcock, and 18 inches in length
from point of bill to middle of forked tail. The upper parts
of head and body are black, mottled with reddish-brown and
erey ; the breast is black, with slight reddish purple reflec-
tions; the under parts black, mottled with red, and spotted
with white. The birds have the blackish bill of the black-
cock, and the scarlet free fringed margin of membrane over
the eyes, as in the Red Grouse.
Tail is slightly forked, and differs from Macgillivray’s
specimen, in having eighteen feathers like the Blackcock,
instead of sixteen as in the Red Grouse.
The legs have the tarsi closely feathered all round, like the
Red Grouse, there being no bare space on the back part, as
exists in the Blackcock; and the feathers are as close and
thick as in the former. The feet are feathered for about a
third down the toes, whereas in the Blackcock the feathering
stops at the commencement of the toes, and in the Red
Grouse it extends down to the claws. The toes are mar-
gined with pectiniform scales, as in the Black Grouse ; and
the claws are long, arched, and slender, ike the Red Grouse,
and do not resemble the shorter and stronger claws of the
Blackcock. The birds agree closely with the description of
a hybrid given by Macgillivray in his “ British Birds,” and
with those formerly exhibited (Proc. vol. 11. p. 245). They
were procured by Mr Aitken, farmer, Listonshiels, and had
been killed on the 8th December, on the Pentland Hills,
some twelve miles west of Kdinburgh. The birds were pre-
pared by Mr Sanderson, George Street.
(5.) Botaurus stellaris (Selby.) The Common Bittern.—A
beautiful male Bittern, now become one of our rare birds,
shot on the 24th January, near Balerno, in this county,
was exhibited. Its large membranous stomach contained a
couple of frogs, a large and a small one. The body of the
i

large frog was much altered by the digestive process, but its
hind legs, which projected upwards into the gullet, were
very little changed. The caput cecum was small, measur-
ing only about one-eighth of an inch, and had no projecting
cecal appendages. Another specimen, a female, was also
examined ; it was shot in October last, between Ayton and
Coldingham, Berwickshire.
(6.) Podiceps cristatus (Penn.) Great Crested Grebe,
(‘‘ pellet” in stomach).—The specimen exhibited was shot in
the Firth of Forth, near Queensferry, on 27th January
1862. It measured 21 inches in length; wing from carpal
joint to point of primaries, 7% inches. Bill nearly two
inches in length, of a pale carmine tint, with a dusky stripe
along its ridge, and tip of greyish white ; small white spot
between eye and bill. In wing, the primaries are brown,
one or two of the last being slightly tipped with white;
secondaries pure white, with the exception of two or three
of the last feathers, which are more or less tipped with
brown, and the coverts of the primaries and secondaries are
brown; the humeral feathers and their coverts are pure
white, and this white colour runs forward along the lesser
coverts at the anterior margin of wing, gradually diminish-
ing in breadth towards the carpal joint. The scapulars are
dark-brown or greyish-brown, like the rest of the back. The
expanded wing, therefore, displays the primaries brown,
and a broad band of brown obliquely crossing the white
wing from the carpal joint to the points of the last secon-
daries. The axillaries are white. Feet and legs greenish-
brown on outside; inside, pale yellowish-green. The bird
is a female; the muscular gizzard measured 24 inches in
length, with a thick, rugose cuticular lining; it contained
a nearly dry rounded mass; about the size of a small walnut,
~ which, when broken up by the finger, was seen to consist of
various black and white feathers, apparently taken from the
bird itself, and the remains of what appeared to be the spines
and skins of shrimps or other crustaceans. Masses of this
kind have been often noticed in the stomach of this bird,
and have been variously described. The pyloric orifice of
the stomach was seen to be very small, and it was at once
366 Proceedings of the Royal Physical Society.
apparent the mass of feathers never could be passed by
the bowels; whereas the cardiac opening of the stomach
was large, with a large glandular proventriculus, forming a
band 13 inch in breadth. It was manifest, therefore, this
mass was simply a “pellet” of feathers, and the indigestible
parts of its food, ready to be cast up by the mouth. From
the lower bowel there were two ceca, one 13, the other 24
inches in length.
Macgillivray, in his “‘ History of British Birds,” says, “ Its
food consists of fishes of various kinds, aquatic insects,
reptiles, and crustacea. Along with remains of these are
usually found in the stomach numerous large curved feathers,
which it probably picks up as they float on the water,
and which are no doubt intended to facilitate digestion.”
How, he does not tell us.
In Professor Fleming’s “ British Animals” we are told
that he found in the stomach of a young Podiceps cornutus
‘a concretion upwards of half an inch in diameter, con-
sisting of its own belly feathers, closely matted together.
Montagu, in his Supplement, states, that he observed the
same occurrence in the red-necked and crested species. Are
these to be considered as analogous to Bezoar’s ?”
Yarrell, in his ‘‘ British Birds,” alludes to “ this habit of
the grebes swallowing feathers alone,” and says it “‘ appears
to be peculiar to the grebes only. From fish bones being
found occasionally mixed up with the feathers, there is cause
to suspect these birds bring up the more indigestible part
of their last meal, as hawks, &c., are known to do.”
From their anatomical structure, there cannot be a doubt
of the fact of this bird bringing up pellets, and the presence
of the feathers will rather facilitate the completeness of the
operation; being possibly swallowed for the very purpose of
assisting to clear out or brush away from the inside of the
stomach the indigestible and spiny portions of the skins of
crustacea, fish bones, &c., which, without some arrangement ©
of this kind, might cause considerable trouble and uneasi-
ness to get quit of.
(7.) Podiceps rubricollis (Penn.) ed-necked Grebe—A
young male, showing a slight appearance of red on the
Ormthological Notes. 367
feathers of lower part of neck, was shot on the River Tay, in
the month of January, and is exhibited by my friend, P. A.
Dassauville, Esq. A young specimen was obtained from the
stomach of a cod, by our member, Dr John Anderson. The
bird was in good preservation, and was presented by him to
the Natural History Museum of the University ; the cod
measured 33 feet in length, and was not in good condition ;
it was caught in the month of November on the east of the
Isle of May. The Red-necked Grebe is stated to be more
decidedly marine in its habits than others of the grebes ;
and this instance of its capture by the cod fish, may perhaps
be considered an additional proof of the correctness of this
opinion.
(8.) Podiceps cornutus (Penn). The Horned or Sclavonian
Grebe.—A male and female in their full summer plumage,
in the possession of Mr Sanderson, George Street, were ex-
hibited. They were shot on the 20th of June 1860, by Far-
quhar Campbell, Esq., at the small loch of Killisport, on his
property of Ormsary, Argyleshire. These birds are not
known to breed in Scotland ; in this instance, however, from
the season of the year, and from the locality to which they
seemed attached, they were considered as probably rearing
a brood of young.
(9.) Podiceps auritus (Penn). The Hared Grebe.—The
bird exhibited was found by Mr John Blackwood, George
Street, in the early part of January, on the sea-beach within
the grounds of Dalmeny Park, near Edinburgh, the seat
of the Earl of Rosebery. It is easily distinguished from
the other grebes by its small size, being still less than the
species last noticed (this bird measured about 12 inches in
length); and by the peculiarly recurved or bent up character
of its bill, which is also shorter than the head. The
upper mandible is broad at the base, and is depressed a
little in the middle of its length; its outline rising slightly
upwards towards the tip. The outline of the lower mandi-
ble is nearly straight at the base, and rises rapidly upwards
towards the point, giving it the appearance of being cut off
obliquely at the point. The bill is black, tinged with blue,
and horny white at the tip, the base of lower mandible

being yellowish. This specimen is probably a young bird
in winter plumage; it has the upper parts of head nearly
black, feathers rather prolonged at sides of hind head ; neck
and back brownish-black; chin, and across upper part of
neck white, a greyish band crosses front of neck; and be-
low it is silvery white, the flanks being dashed with brown.
Wing: primaries, dusky, first and second nearly equal, rest
gradually diminishing in length; secondaries, pure white ;
the coverts brown; below, white; length from carpal jomt
5 inches. Legs and feet dark green, rather lighter on in-
side. Macgillivray says he has very seldom met with this
bird in Scotland; and Sir William Jardine states he has
never personally found it. It is the rarest of the British
Grebes.
VII. A Large Specimen of the Wild Cat (Felis catus ferus),
recently shot on the property of the Harl of Seaforth, in
Inverness-shire, was exhibited by Edward Hargitt, Esq.
VIII. Mr Rozert Brown exhibited to the Society a beautiful specimen
of Astrophyton scutatum* from Davis Strat, with the following Note.
Twelve months ago to-day I sailed to the Arctic Regions,
for the purpose of studying some points in Natural History to
which my attention had of late been directed. During the
eight months I was away, I visited various parts of the Polar
Regions, the seas round Jan Mayen, Spitzbergen, and the
east coast of Greenland, the west coast of Greenland, and
crossing the top of Baffin’s Sea to Lancaster Sound, that
portion of the American coast bordering Davis Strait, &. &c.
From a variety of causes—among others the late severe
winter and spring (the latter of which we ourselves expe-
rienced, the former we were told of by the Eskimo), and
the comparatively still summer, blocking up the shores
with ice, which was not dissipated before we were forced to
seek a milder climate—my voyage was not so successful,
from a scientific point of view, as, under other circum- —
stances, it might have been. I however gained valuable
experience, which I hope soon to make use of, and which

has well repaid me for any little hardships and dangers
I may have undergone in gaining it; and I take this op-
portunity of thanking Captain George Deuchars of the s.s.
‘“ Narwhal,” and his officers, for the ready and intelligent
assistance they tendered me whenever it lay in their power.
The few observations which I have been enabled to make, I
shall have the honour of laying before the Society at a future
time. In the meantime I exhibit this specimen of Aséro-
phyton scutatum, Link, Flem., e¢ Forbes (Brit. Hchin., p. 67),
which I obtained, m September 1861, on the west side of
Davis Strait, about a mile off Cape Kater, clinging to a
whale line, from 150 to 200 fathoms—rocky and clayey
bottom. It was laden with ova of a deep-red colour. I
found nothing in its stomach but Diatomacez, and a spe-
cimen of an HEntomostracan, closely allied to, if not iden-
tical with, Cetochilus arcticus of Baird, in the ‘‘ Appendix to
Sutherland’s Voyage,” vol. ii. p. cciii., the presence of which,
however, may, with a specimen of a species of Yoldia em-
braced in its arms, be only accidental. (It may be men-
tioned as a curious fact, that this Cetochilus forms a great
portion of the food of the “commercial” whale (Galena
mysticetus), a much disputed point, and of some of the
minuter species of Acalephe.)
_ Astrophyton scutatum has been occasionally got among
the Northern Isles of Scotland (where it bears the rather
classical name of Argus) and Norway.*
It has been found, however, very rarely, and at distant
periods, in the Arctic seas. Otho Fabricius, in his remark-
ably accurate Fauna Groenlandica (Hafniz et Lipsiz, 1780),
speaks of it (p. 372) as follows :—“ Asterias caput meduse.
Hanc in museo plurimum reverendi Dn. Egede de colonia
Jacobshavn (ni fallor) missam, vidi: unde concludo, in sinu
Disco dari ; non autem vivam ipse offendi.”
Whether Fabricius refers here to Hans Egede, the pioneer
missionary of Greenland (1721), or to his son, Paul Egede,
- also a missionary in Greenland, and both of whom published

works on the country, does not appear, though in none of
them can I find any account of this animal. The Chevalier
Charles Louis Giesecke, who passed several years in Green-
land, engaged in the study of its Natural History, in his
article ‘‘ Greenland,” in the Edinburgh Encyclopedia, vol. x.
p- 502, notes as follows:—‘‘In Disco-Fiord is found the
Asterius caput meduse.” He is apparently here, as in many
other places, only copying the doubtful record of its occur-
rence by Fabricius.
There is no notice of itin Hans Egede’s work on Greenland
(Die Gemle Greenland nye Perlustration, 1729); or in the
fuller and better work by David Crantz, one of the Mora-
vian Unitas Fratrum (Historie von Gronland, 1765; English
trans. 2 vols. 1820), both of whom studied very closely the
Arctic Fauna with the best lights of the age. My attention
has however been called to a note by Mr Gwyn Jeffreys, in
the “ Annals of Natural History,” vol. vii. p. 253, where he
refers to Sir John Ross having got a single specimen far
north, which was described by Dr Leach, under the synonym
of Gorgonocephalus arcticus, and is now in the British Mu-
seum. It was obtained from 1600 fathoms soundings in soft
mud, and measured, when expanded, two feet.*
My specimen is much larger and finer than any I have
ever seen got in the British seas. It thus appears that, with
the exception of the doubtful indication of its occurrence in
Disco Fjord, by Fabricius (cerciter 1760), and that by Sir
John Ross in 1819, this specimen found last year is only the
third got in the wide Arctic sea, north and west of Greenland.
None of the Government exploring expeditions have brought
it home, though it is quite possible that some of the many
naturalists who have studied the Arctic fauna since the days
of Fabricius—Eschricht, Staeger, Kroyer, Moller, Hoeg, Olrik,
Rink, Reinhardt, Otto Torrell, &.—may have met in with it,
though I am not aware that it is on record. Disco-Fyjord, a

met with it in his “‘ Voyage to Spitzbergen, ¢. P. f. #.,” though Phipps (Lord

North Pole ;” apud Scoresby, ‘‘ Arctic Regions ;” though it was afterwards
got in Davy’s Sound on the east coast of Greenland.—(Scoresby’s Voyage to
Greenland, fc. ; Zoological Appendix.)

narrow inlet of the Island of Disco (lat. 68° 58’ 42” N., long.
53° 13’ W.), appears to be a very likely place for it. It is
almost opposite Cape Kater where I got it, and where it
appears to be pretty abundant; for broken pieces occasion-
ally came up on the whale-lines afterwards.
A curious idea seems to have prevailed in Bishop Erick
Pontopiddan’s day regarding this animal. After mention-
ing in his excellent ‘‘ Natural History of Norway,” part 1.
pp- 179-80 (Lond. 1755, English trans.), that it is rarely got
on the Norwegian coast, and is called Sée-Navle by the Nor-
wegians, and Sde-Soel or Sea Sun by the Dutch sailors, who
frequently find it in the West Indies, according to Geo.
Marcgrave’s account, in his “ Historia Naturalis Brazilie,”
lib. iv. cap. xxi, he states, in all good faith, the following
extraordinary notion, though, with a lack of credulity he has
hardly been given credit for, repudiating it :—“ This strange
and wonderful fish or korstrold is said to be only the young, or
perhaps only the germ, of the roe of that great and frightful
monster, which is here called Kraake [Kraken Anglice]. But
as far as I could get information from several fishermen, who
all agree in their accounts, this cannot possibly be true.”
Though a rare animal, this ‘ Korstrold,” from its bizarre
form, seems to have attracted the attention of all the “ enge-
nuous” naturalists of an early date, as well as more modern,
and to have received (after a fashion not peculiar to our
time) a variety of names,—viz., Sternfisch, J. C. Adelung,
Geschicte, &c., p. 381, tab. xvii. fig. (1768); “‘ Stella ma-
rina 1. Ionstoni, Lnsect., tab. xxiv. fig. 11” (fide Fab.) ;
Stella arborescens (Rondoletius and Gesner) ; Asterias caput
medusee (Linnzeus, Muller, &c.) ; Asterias arborescens (Pen-
nant); Huryale verucossum (Lamarck); Huryale scutatum
(Blainville), &c.
Most of the early authors give distinguishable figures of
it. That of Pontopiddan is the best. Among modern, that
of Professor E. Forbes is the only good portrait of it, but,
from its want of colouring, his figure does not do full justice
to the varied hues of the starfish. The coloured figures in
Griffith’s beautiful edition of Cuvier’s Regne Animal, as also
in the “Crochard Edition” of same work, are mere pictures.

I. Notice of Indian Insects exhibited at last meeting by Mr Elliot of
Wolfelee. By R. F. Loean, Esq.
Although not present at the last meeting of the Society,
when Mr Elliot’s beautiful drawings of Indian animals by
native artists were exhibited, I have since had the pleasure
of inspecting them, through the kindness of Dr Coldstream ;
and with reference more especially to the entomological
portion of the collection, I wish to bear testimony not only
to the intrinsic beauty and fidelity of the drawings, but also to
their high scientific value, as comprising the transformations
of many insects whose history has been hitherto unknown
to science. Besides figures of the larve and pupe of many
of the Papilionide, Pieride, Nymphalide, &c., some of
which have been already figured and described, the collec-
tion includes some most interesting details of the trans-
formations of the Heterocera. Among the Woctue, those of
the genera Hypocala, Hyblea, Ophideres, Achaea, Lagop-
tera, and Serrodes, are especially worthy of mention. The
larvee of Hypocala have no apparent affinity with those of the
Catocalide, immediately before which they stand in Guenee’s
arrangement. Those of Opilideres, of which Guenee re-
marks, ‘‘Je desirerais vivement connartre les chemilles de ce
genre singulier,” are quite as remarkable as the perfect in-
sects. They are elongate and cylindrical, lke those of the -
Ophiuside, and the anterior pair of ventral claspers is imper-
fect ; but instead of being attenuated posteriorly and ante-
riorly with a pair of small tubercles on the eleventh seg-
ment, the latter forms a large conical protuberance, as in
Dr James M‘Bain on the Development of Fish Spawn. 373
the larva of Notodonta or Amphipyra, and the rest of the
body is uniformly cylindrical, the fifth and the sixth seg-
ments bearing a pair of large eye-like spots, somewhat like
those of the larva of Cherocampa. The position, when at
rest, is most remarkable, the body resting on the three pairs
of perfect ventral claspers alone, with the anterior segments
elevated and incurved, after the manner of the Sphinges,
and some of the Geometre, while the posterior segments are
elevated in the air after the fashion of the genus Notodonta.
The drawings are on their way to London, I believe, to
be placed in the hands of Mr Moore; so that their details
may be expected to be embodied in the forthcoming volumes
of the Descriptive Catalogue of the Insects in the Museum
of the Hast India Company.
II. Notice of the Development of Fish Spawn from the Firth of Forth,
By James M‘Barn, M.D., R.N.
On Tuesday the 11th instant, when examining fish spawn
under the microscope, I observed a free and complete rota-
tion of the embryo in the ovum, which rotatory movement
was repeated at short intervals. The spawn had been
dredged up four days previously in 144 fathoms water, half
a mile to the westward of the Isle of May; and in all the
ova which had a clear transparent appearance the same rota-
tory motion was observed. ‘The following day, on making
similar observations, the embryos were still found alive,
and rotating freely in the ovum; and fresh spawn dredged
up at the same place exhibited similar activity of embryonic
movement. ‘The spawn in which this vital action was seen
is said by the fishermen to be the herring spawn ; and to as-
certain, if possible, to what species it really belongs, I pre-
served small portions of the spawn in sea-water. On the
18th instant, I was pleased to see a numerous brood spon-
taneously extruded from the ova, swimming freely about in
the vessels in which they had been placed.
The ova were about 5th of an inch in diameter, and the
young fry, when first extruded, measured two to three lines
in length. A few of the young fish are now, eight days
374 Proceedings of the Royal Physical Society.
after extrusion, fully half an inch long, and have almost
parted with the nutritive portion of the vitellus. There are
many, however, that have made less progress, and have still
a large yelk-mass attached to the upper part of the thorax
immediately behind the pectoral fins. On the third day
after exclusion from the ova, the mouth and jaws were quite
distinct, the pectoral fins had appeared, and the outlines of
the branchial arches were plainly visible. The cardiac con-
tractile sac, which was seen in the embryo, was now found
to contract and dilate sychronously with a fluid movement
along the ventral aspect, which could be traced backwards
four-fifths the length of the fish, where a notch in the deli-
cate fin membrane appeared to indicate the separation be-
tween the abdominal and caudal portions of the animal.
The progress of development has been watched daily, and
will be more fully detailed when the observations are com-
pleted.
As it is uncertain whether the young fry will exist long
enough to pass into their adult condition, I have thought it
proper to give this brief notice to the Royal Physical So-
ciety, and at the same time to exhibit living specimens,
along with pencil drawings illustrating the various phases
of development from the first rotation of the embryo seen
in the ovum until the present time.
Dr T. 8. Wright mentioned that he had noticed a similar
development, but was doubtful if the ova were herring
spawn.

IV. On Phryxus Paguri. By Joun Anperson, M.D.
In the month of May last year, when dredging in the
Firth of Forth, I had the good fortune to meet with this in-
Dr John Anderson on Phryxus paguri. 375
teresting, and, according to its discoverer, Rathke, ‘‘ recht
selten parasit.” As itis a new and interesting addition to
the fauna of the Scottish seas, I shall shortly describe its
external characters. This remarkable Bopyridian is fixed
with its dorsal surface to P. Bernh., and from its anomalous
position, one is apt to confound the ventral with the dorsal
surface of the body. By means of its seven prehensile feet
it adheres with considerable tenacity to the soft abdomen of
the crab. In Phryxus, as in the other Bopyride, the pro-
portions of the female greatly exceed those of the male in-
dividual, which is always found associated with, and leading
a parasitic life upon, the former. Differing in size, they also
differ in external form.
The female always selects the left side of the crab as its
habitus, which, I suppose, is owing to this side of the crab
being always in relation to the widest part of its appro-
priated dwelling. It is about half an inch in length and a
quarter of an inch in breadth ; all my specimens were of a
pure white colour. The body of the animal, with the excep-
tion of the caudal appendage, is nearly of the same breadth
throughout its whole extent ; its anterior margin is rounded.
As already stated, the dorsal surface is applied to the
abdomen of the crab, and is flat, but slightly concave in the
centre, and is divided into seven segments, each segment
bearing a pair of prehensile feet. The ventral or upper-
most surface is in relation to the shell in which the crab
lives, and, like the dorsal, is distinctly segmented, but is
hidden from view by six leaf-like membranes, which form
the breeding cavity for the ova.
The head of the animal cannot be detected on the ventral
surface until the bladder-like pouches which overlap it are
removed. This portion of the head consists of a large under
lip, behind and over which are placed two valve-like bodies ;
these bodies, in reality, are the altered pouches of the head
segment. When viewed from the dorsal aspect, the head
has a quadrangular appearance, bearing upon the centre of
its anterior margin a small rounded process. The first pair
of antenne are small, and consist each of three joints, the
terminal joint bearing a few bristles. The second pair are
VOL. II. 3c
376 Proceedings of the Royal Physical Society.
much larger than the first ; they consist each of four joints,
the two terminal joints being provided with a few bristles.
Eyes are wanting in the female.
The segments of the dorsal surface of the body are sym-
metrical, with the exception of the sixth, the unsymmetri-
cal character of which is due to the animal being slightly
curved, the convexity of the curve being towards the right
side, and involving this segment. The segments gradually
increase in size from the third to the sixth; the latter is very
much expanded on the right side of the mesial line, corre-
sponding to the convexity of the curve of the body. The
seventh segment is symmetrical, but very much smaller
than the preceding one. All these segments bear feet, which
are very much distorted. From the different relative pro-
portions of the segments, the feet are placed at various dis-
tances from each other. The first pair closely surround the
head, and have the second pair intimately applied to their
external margins. The third pair are placed very near the
second, but slightly posterior to them ; and the fourth pair
are removed at some distance from the finite and also from
the fifth pair, which lie behind them. A considerable in-
terval exists between the fifth and sixth pair of feet, which
is especially marked upon the right side of the animal. The
sixth and seventh pair le contiguous to one another.
Projecting beyond the posterior margin of the body
(seventh segment) are the five branchial segments, all of
which, with the exception of the terminal one, carry a pair
of oval pedunculated branchie. The segments are rounded,
and diminish in size as they approach the extremity. The
terminal one ends in an oval-shaped process, which pre
performs the same function as the branchie.
The six ventral membranes of the breeding cavity in-
crease in size as they approach the posterior extremity.
The first or head pair differ in their form from the other
five, from which they are also distinguished by their edges
not being overlapped.
They appear to be supported upon very short jointed
stalks, and they consist of two portions, an anterior and pos-
terior. The anterior portion is oblong in form, and bears

upon its ventral surface four rounded tubercles, and has a
curious crescent-shaped pedunculated appendage attached
to the posterior extremity of its external margin; the pos-
terior portion is about half the size of the anterior, and
is convex externally, and slightly concave on its internal
margin. |
The connections of the remaining five pouch-like mem-
branes are as follows :—

The second membrane covers the valve-like leaf of the head
and is overlapped by the third, which is partially covered by
the fourth ; this, again, overlaps the antericr extremity of
the fifth, the remainder of which, and the posterior half of
the fourth, are hidden from view by the largely developed
pouch of the fifth, sixth, and seventh segments. By this
arrangement the plates visible from the belly side are the
third, fourth, and sixth. The sixth plate is minutely serrated
along its margins. In one of the specimens I examined,
the fourth, fifth, and sixth membranes were filled with ova.
The pale-yellow coloured male is a very little more than
one line in length, and consists in all of nine segments,
which diminish in size as they approach the caudal extre-
mity. The anterior segment (head) is symmetrical, and
bears two eyes. Projecting beyond its lateral margins are
the external antenne, which consist of four joints. Placed
internal to these, and completely concealed by the head,
are the internal ones, which only consist of three joints.
Each of the remaining segments, with the exception of
the terminal one, carries a pair of feet which are provided
with sharp claws. The segments are rounded at their ex-
ternal margins.

1. Clava nodosa (n. sp., T. 8. W.)
‘‘Polypary creeping. Scleroderm membranous, ‘ Polyps
single, small, aurora-coloured, each springing from a small
knot of convoluted tubes.’ This zoophyte was found on the
fronds of Delesserva sanguinea at Queensferry and Largo.”
The very delicate threads of the polypary creep over the
fronds of the seaweed, and at intervals twine themselves into
a convoluted knot of membranous tubes, from which a single
polyp arises. The species occurs only at low tide mark;
while C. repens, for which it may be mistaken, is found in
shallow rock pools.
2. Acharadria larynx. (Pl. XVII. figs. 7, 8.)
‘ Polypary branched, spirally twisted. Polyps pale orange,
with two rows of tentacles. The lower row from 4 to 12, the
upper row from 2 to 8 capitate.”
On stones carrying Caryophyllia Smithi, received from
Ilfracombe. This little Tubularian was about a quarter of
an inch high, with three polyps, and resembled in habit
Tubularia larynx. It bears the same relation to Vorticlava
that Corymorpha does to Tubularza larynx.
3. Zooteirea religata.
I described this animal to the Society about dis years
ago. It is a stalked Actinophrys. The body, asin other
animals of this class, consists of two elemental tissues,
to which I have given the term ectosarc and endosare,
—terms which have been adopted by Dr Carpenter. The
ectosarc or external tissue is prolonged into a thick brush
of the most delicate contractile palpocils or tentacles, like
threads of spun glass (Pl. XVIII.), by which the animal
is constantly seizing small organic particles, and convey-
ing them to the endosare or inner tissue, which is the
nutritive element. I stated that the stalk was formed of
a prolongation of the ectoderm, similar to the tentacles;
but, having again discovered large colonies of these animals
last summer, and again this winter, I have been enabled to
study the structure of the stalk more closely, and find that

it is an elastic tube, which appears to consist of denser tissue
than either of the elements of the body. The axis of the
tube is occupied along its whole length by a powerful mus-
cular band, which is well seen in the figure (Pl. XIX. fig.
1d), in which the tube is distended with water, as sometimes
occurs. The animals are very sluggish, remaining for days
motionless, with all their rays extended; but the moment they
are touched they vanish, drawn close down by their powerful
muscular apparatus into the interstices of the shells in which
they are generally found. Zooteirea multiplies by gemma-
tion. The bud, which is given off close to the stalk, sepa-
rates as a minute Actinophrys, which instantly fixes itself
and develops its stalk. The lower part of the stalk is in-
cluded in a mass of gelatinous tissue into which the animal
can entirely retract itself. The long tentacles of Zooteirea
religata can only be properly brought into “ black ground
illumination,” when they appear like the rays of a silvery
star, slightly curving under the influence of currents in the
waters. :
4, Freya (Lagotia) obstetrica, Freya stylifer (n. sp, T. S. W.)
It is now some years since I described several species
of the new genus Lagotia to the Society. It appears, how-
ever, that Claparede and Lachmann had already consti-
tuted the genus Freya for animals evidently belonging to
my genus Lagotia, in a memoir which they communicated
to the French Academy, which memoir was printed after my
communication to this Society. The species of Freya dis-
covered by them differed from any of my species, and I have
now to describe two other species of this very remarkable
genus. LPreya obstetrica (Pl. XIX. fig. 4.)—* Lobes of rota-
tory organ very broad, not folded; the tips bluntly rounded
and incurved, so as to resemble very closely the blades of
the obstetric forceps. Body fusiform, scarcely longer than
the rotatory lobes. Nucleus large, colourless, surrounded
by dense green pigment. Body and rotatory lobes covered
with striz, bearing fringes of cilia. Cell flask-shaped, with-
out a trumpet-shaped mouth. Colour of animal and cell
pale bluish green.” Freya stylifer (figs. 5, 6.)—‘* Rotatory
lobes short, narrow, and widely expanded, one of the lobes
bearing at its tip a fleshly prolongation or style as long as
380 Proceedings of the Royal Physical Society.
the lobe; cell tubular, without trumpet-shaped mouth; cell
and animal colourless.” Freya stylifer is the smallest spe-
cies I have yet seen of the genus to which it belongs; when
contracted within its tube, it projects the curious style,
which is doubtless a sense organ, beyond the opening, only
entirely retracting it when rudely disturbed.
During the last summer I had an opportunity of watching
another species of Freya (2. producta) building up its re-
markably constructed cell. The cell of this species, which
is often immensely prolonged, is formed of a spiral ribbon
of chitine, cemented by a thick internal layer of soft green
sarcode, secreted by the body of the animal, so that the
whole forms a hollow tubular spring, like the spiral wire
tubes formerly employed for conveying gas to moveable
burners. These tubes will therefore bend aside like a wil-
low twig on any rude contact from the animals which are
constantly dashing about, and will instantly regain their
proper position. The young Freya producta, which is a free
swimming larva, fixes itself, and secretes the lower part or
body of the cell from the outer surface of its body; it then
begins to form the elongated neck by depositing the chitine
and sarcode on the upper edge of the constantly lengthening
ribbon, carefully moulding the plastic materials with its two
short rotatory lobes, which it uses like a pair of hands (Pl.
XIX. fig. 2), just as Sabella and Serpula mould their tubes
with their hand-like secreting leaflets. Having built its
tube to the requisite length, it finishes it off with a hand-
some trumpet-shaped mouth, and then retires to develop its
long rotatory lobes. Occasionally the animal outgrows its
dwelling-place,; and finds it necessary to lengthen its tube.
For this purpose a large quantity of dark green matter is
collected in the body of the animal, a little below the rota-
tory organ (fig. 3 6), and from this part chitine and sarcode
are secreted, which are instantly moulded into shape by the
rotatory lobes, and a new spiral tube rises up from within
the trumpet-shaped mouth of the old one (fig. 3 a).
5. Chetospira maritima (n. sp., T.S. W.)
Two species of this remarkable animal have been noted by
Lachmann—C. Mullert and C. Mucicola. Cheetospira is de-
fined as a Stentor, in which the ciliary spiral and the paren-

chyma of the body supporting it are drawn out into a long
thin process. When the animal issues from its tube, it pro-
trudes its ciliary organ as a fleshy column, fringed on one
side by a row of very long motionless cilia, but in an in-
stant the column is twisted into a spiral, and the cilia are set
in violent motion, urging currents of water towards the
mouth. The marine species approaches in character, as to
its rotatory organ, to C. Mullert, while it inhabits a mucous
tube like that of C. Mucicola.
6. Oxytricha longicaudata, (Pl. XIX. figs. 7, 8.)
This remarkable animal, resembling very much Oxytricha
retractilis, described by Claparede and Lachmann, was found
in great numbers with Chetospira maritima. The tailin this
species is fully twice as long as that of Oxytricha retractilis,
and is dragged after the swimming animal like a trailing
rope, when suddenly the extremity of the tail is fixed by
the long cilia at its extremity, and the Oxytricha, by violent
contractions of its tail, jerks itself backwards and forwards
in the most violent manner. The structure of tail, under
an excellent power of eighty diameters, presents a peculiar
striated and plaited appearance, like that of voluntary mus-
cular fibre, but I could not make anything of it under higher
powers.

VI. On peculiar Hooked Spines on Ophiocoma bellis, with Observations
on the Spines of other Ophiocome. (Plate XX.) By Caas. Wm.
Pracu, Esq., Wick. (Specimens and drawings were exhibited.)
On the 26th January 1859 a paper of mine was read, giv-
ing an account of the discovery of hooked spines on Ophio-
coma rosula, of which I had seen no notice in any work on
British star-fishes. In April of the same year, when in
London, I called at the Museum of Geology, Jermyn Street,
and on mentioning this to Professor Huxley, he at once re-
ferred me to a work in which similar spines were figured
from star-fishes found in the Mediterranean—viz. Miller
and Troschel’s ‘System der Asteriden, 1842.” Two species
are figured and described as having jaw-like hooked spines—
one at TableIX., fig. 4,—Ophionyx armata,—another at Table
X., figs. 1 and 6—Asirophyton verrucosum. I only mention
this work, so that any one feeling an interest in the subject
may know where to refer. On the 14th June 1861, having
obtained a large mass of star-fishes from the stomach of a
cod, I found that about a hundred were Ophiocoma bellis.
After carefully washing them, I placed portions under the
microscope, and found that the under sides of the rays were
furnished with hooked spines, like those I had before found
on Ophiocoma rosula. They are not quite so distinct, nor
so constant in form, and do not extend so far on the rays
towards the disk ; for about the middle, they become more
and more obscure, and before reaching it are straight, short
spines. As well as the hooked-jaw like ones, the straight
spines above these have hooked tips. Ophiocoma bellis is
very abundant here, and is a favourite with cod-fish, as
proved by the immense quantities found in their stomachs.
Last night, in searching amongst my stores, I found enclosed
in glass a specimen of Ophiocoma granulata, thus placed
more than nine years ago; and, although pretty perfect, it
was not in such a good state of preservation as I could have
wished. Being the only one available, I was glad to have
it. Although no hooked jaw-like spines are to be found on
the under side of it, a provision has been made for its wants,
by furmshing large hooks to the lower straight spines. These

are most hooked towards the ends of the rays. There is
however, a peculiar feature to be noticed in this species:
although it has not the jaw-like spine, it is furnished with
“two little obsolete or undeveloped spines.” Ophiocoma
rosula and Ophiocoma bellis have one only of these “‘ obsolete
spines”—valves I would rather call them—for an opening
may be seen when these are raised, out of which the pin-
nated cirrhi are protruded. I regret exceedingly that I can-
not find the drawings of Ophiocoma rosula where these cirrhi
are shown, and which I sketched from a living specimen.
I find in a specimen of Ophiocoma Ballit that the lowest
spines on the under side of the rays are crowned with small
hooks ; and I have every reason to believe that most of the
Ophiocoma are more or less provided with hooks, either on
straight or jaw-like spines. _

VII. The Geology of Moffat, Dumfriesshire. By W1iiu1am
Carrutuers, Esq., F.L.S.
Lathology.
I purpose in this paper describing the geological features of
the district around Moffat, taking the village as my centre,
and including all that lies within a radius of four or five miles.
The district is situated in the centre of the immense Silurian
tract of the south of Scotland; its predominant rocks conse-
quently belong to the Silurian period. A red sandstone lying
unconformable to them is the only other stratified rock. The
superficial deposits are not numerous; they consist of boulder
clay, gravel and sand, peat and shingle. 631

IX. Notice of a Fetal Narwhal (Monodon monoceros, Linn.) By
Rozert Brown, Esq.
Mr Brown exhibited a small foetal specimen of a Nar-
whal (fonodon monoceros, Linn.); and stated that another
foetus was also found in the uterus of the same animal,
which was captured in Davis’ Strait, June 23d, 1861.
In the “ Linnean Transactions” (vol. xii. pp. 620, 621,
“ Extracts from Minute Book”), in a letter from Mr W. R.
Whatton of Manchester, it is noted, that in the summer of
1821, while a Hull whale ship was beset in the ice in the
VOL, I. 3M
448 Proceedings of the Royal Physical Socvety.
North Seas, the crew took a female Narwhal having a tooth
in the upper jaw, perfect, and in every respect like that of
the male, though not so long. The sex of the animal was
satisfactorily ascertained in cutting up, when two fatuses
were taken out of it. Mr Brown was acquainted with similar
instances of the “horn” being protruded in the female Nar-
whal; and though it is said to have been seen with two
young following it, yet the instances mentioned were the
only ones with which he was acquainted, in which the subject
had been brought to an experimentum crucis. In all likeli-
hood, the Cetacea in this respect follow the same laws as
the other Mammalia, though our opportunities for observing
the former were much more limited; and hence the value
of every fact, however apparently triflmg, being put on
record.
Mr W. 8. Youne proposed a vote of thanks to the Presi-
dents and other office-bearers, which was unanimously
agreed to, and the Society adjourned until the commence-
ment of the next Session.
