PREFACE.
-o-0«^jt£oo-
O write a Preface year after year for a volume
like Science-Gossip, to mean the same thing,
and yet to say something new, would be a tax
upon the ingenuity of the most skilful writer.
Nevertheless, the Editor feels it both a duty
and a pleasure to take such an opportunity of
expressing his gratitude towards so many
cheerful helpers, his sympathies with diligent students
and inquirers with whom he has been in silent monthly
communication, and his hopeful anticipations that the time to
come may find him surrounded by as many friends as at the close
of the eventful year 1878.
The last four years have been fruitful beyond measure in Scientific
discoveries. In Physical Science, the numerous revelations have
been almost startling in their novelty, and these have culminated
in that simple and yet wonderful instrument, the Microphone. To
listen to the tramping of insects is like hearing the " footfalls on the
boundary of another world." Is it possible that the Microphone will
be to organic sound what the Microscope has been to vision ? Shall
we listen to the love-narratives of insects as we do unaided to those
of birds, or be possible hearers of their domestic squabbles ?
Unhappily, it would seem as if Science, like some land of
Goshen, were the only arena where Peace may find a perpetual
home! For, although scientific men, as inheritors of a long ancestry
of the spirit of partisanship, cannot avoid taking sides in debating
the great questions which are continually raised in their unfettered
investigations of natural phenomena; they do not condemn each
PREFACE,
other to pains and penalties for daring to disagree. No sword is
here wielded, nor artillery thundered, to determine by force what
calm reason finds herself unable to settle. Rather, a greater incentive
to further inquiry is produced, to redoubled observation and verifica-
tion of facts, and to renewed diligence in the search after truth, if
haply they may find it ! Will the time ever come when Politicians
will condescend to follow the example of savans ?
It is cheering: to observe the wider love of Nature and the
spread of scientific culture among all classes ; to note how the
pursuit of Science is a bright spot in the lives of toilers at the desk,
the loom, the anvil, and in the field. Our position fortunately makes
us acquainted with diligent and capable students, low in the scale
of worldly wealth and position, whose lives are sweetened by the
new interest in common things which popular Science has created
for them. Long may it continue to be so, and may the day soon
come when men and women will be rescued from their lower natures
by the calm dignity which Wisdom bestows on those who seek her !
As hitherto, our purpose is to keep pace with modern discovery
and investigation, and to throw open our columns to the recording
of new facts. Not less desirous are we of helping the young inquirer,
and of putting him in a way to gain higher and sounder knowledge.
Whilst endeavouring to keep clear of mere gossip, we do not wish
to write above the heads of our large circle of readers by essays on
abstruse subjects. Our aim is to spread and popularize Science,
and to encourage a love of it.
In conclusion, we heartily thank all who have helped us, and
who have promised to continue their aid. At the same time, we
implore the sympathies of those who are unaware of the burden of
correspondence and work entailed in editing a journal like SciENCE-
GOSSIP, and who may feel aggrieved at imagined slights. To each
and all of those with whom we have been in cheerful literary
and scientific companionship for the last year, we wish a " Merry
Christmas and a Happy New Year !"

THE POTATO BEETLE.
A LITTLE OIL ON THE WATERS.
By W. V. ANDREWS.
Corresponding Secretary of Long Island Entomologists' Society, U.S.A.
PHE occasion of the ap-
pearance of this little
article is a paper which
appeared in the Sep-
tember number of
Science-Gossip, writ-
ten by Mr. E. C. Rye.
No one will dispute
the assertion that any-
thing from the pen of
that gentleman, particu-
larly on entomology, is worthy of our serious atten-
tion, and therefore it is that I regret to see him in
the ranks of the alarmists, — already, as I should
judge, too well recruited.
I will assure your readers that to us, who have now
for some years been familiar with D. decemlineata,
the alarm seriously felt in the Old World lest this
insect should visit your shores seems verging on the
ridiculous. I do not, of course, mean that reasonable
precautions should not be taken ; but the idea of
stopping the transmission of dead specimens through
the mails, as I know has been done, and thus pre-
venting your people from making a personal acquaint-
ance with the insect, appears to me to have a ten-
dency to defeat the object in view.
Certainly I should adv.se no Englishman to import
Jive specimens, and I shjuld advise all farmers and
gardeners to rid themselves of the presence of the
beetle, as I should advise them to rid themselves of
a crop of thistles. But if they imagine that its
existence in their fields is likely seriously to injure
■their crops, then I assure them that they are very
much mistaken. We have had this beetle on Long
Island in immense numbers for some years, and I
do not believe that any one has suffered any
appreciable loss through its depredations. Farmers
.all say this.
No. 157.
If any loss have been sustained, it has rather been
through the i-emedy used than through the disease.
And here let me earnestly advise my countrymen — for
I am an Englishman — if the 'ieetle should make its
appearance in the tight little island, to use no Paris
green, or other poisons, with a view to its extermi-
nation. There are two or three sufficient reasons why
such remedies should not be used : —
1. Its application, in any form, is not without
danger. If it be dangerous to wear green silks or to
use green paper for walls, it surely must be injurious
to apply this poison in any way by which its entrance
into the human system is rendered possible, and
probable.
2. The first shower of rain or gale of wind will
remove every particle of the powder from the foliage
of the potato, and either disseminate it through the
atmosphere or imbed it in the soil, to be stirred up
by the hoers or diggers.
3. Its use is entirely unnecessary. For small plots
of land hand-picking by boys or girls is efficacious
and without danger (for I do hope that your readers
are not believers in the foolish stories told of the
beetle being poisonous). For larger lots an ordinary
butterfly bag-net, swept gently along the potato-
tops, will capture more beetles in an hour than Paris
green will kill in a week ; and, by the way, recollect
that Paris green will kill other things besides potato
beetles. An American farmer applied a pretty good
dose of this poison to the potatoes in his garden " one
dewy eve," and on the next morning found four dead
milch-cows in his pasture. The cows had broken
into the garden, and — increased the quantity of beef
in that vicinity.
Mi". Rye tells you that Paris green is a favourite
remedy here, but he does not understand the American
mode of doing things. Some State entomologist or
other probably had ~ friend in the oil and colour
B
HARD WICKE 'S S CI EN CE-GO SSI P.
business, and gave a friendly puff to Paris green.
Then the oil-and-colourman advertises in some
agricultural papers that he has the " never-failing
exterminator " of potato-bugs — Paris green, and the
editor of that journal at once strongly recommends
it. You do not do things in that way in honest old
England, but we do here.
One word of advice. When your potatoes are
four or five inches high, just occasionally turn up
the leaves and examine the under side. If you find a
bunch of orange-coloured eggs, nip them off. They
probably were deposited by D. decemlineata. In a
week or so look again. If you find that the foliage
has been eaten from a plant pretty thoroughly, and
should find a dirty brick-red animal, like that figured
by Mr. Rye, on that plant, remove the animal the
way I have advised. It is the beetle in its larval
state ; and, recollect, that in that state it does most
of its eating. But it is a poor traveller, and does
not wander about unnecessarily. So, when you
have found one from a batch of eggs, you may be
sure the others are near at hand. One stroke from
the net will capture most of them. Work atten-
tively, now and again, and your potato crop will
not suffer. Recollect, however, that other things
besides D. decemlineata eat potato vines. Here we
frequently suffer from the attacks of the Lyttas, or
blister-beetles, which devour lots of potato foliage.
Caution ! Mind, that all striped beetles found
on potatoes are not Colorado potato beetles, but
may be useful little fellows, whose larva; devour
other larv;£ injurious to us.
THE PRONUNCIATION OF SCIENTIFIC
NAMES.
IN regard to the pronunciation of Latin and Greek,
perhaps the confusion of theory and practice is
greater at the present time than it has ever been.
The attempt to give c and g the hard (guttural) sounds
in all such words is really only a part of a much
wider scheme, which aims at restoring, as far as
possible, the actual pronunciation of the ancients
themselves. If these actual sounds can be recovered
with any certainty, there is a possibility that some
time Latin and Greek will be pronounced in a similar
way by all who learn them, to whatever nation they
belong. This is only what is done, as a matter of
course, in the case of all other tongues, and no reason
could be assigned for adopting a different practice in
this instance. Prejudice stands in the way, but we
need not despair of overcoming it. When I began to
learn Latin, I was told that when I travelled in a
foreign country, the language of which was unknown
to me, I should be able to communicate my wants to
any well-educated man by expressing them in Latin.
In writing, of course, this could always be done, as,
in fact, it is in the correspondence of many scientific
men of the present day, especially those who belong
to the Russian, Swedish, and other nations, whose
languages are not generally known. But if two of
these savans met, they would be as entirely unable to
communicate orally with one another as if they knew
no Latin at all — a result which I have no hesitation
in calling ridiculous.
But is there any possibility of recovering the actual
sounds used by the Greeks and Romans at the time
of their greatest literary prosperity? — the last clause
being necessary, because their pronunciation changed
with time, as ours has done. This is not the place to
discuss the question, but the attempt has been made,
and, I believe, with success ; not with absolute
certainty, perhaps, but sufficient to remove, at any
rate, most of the difficulties in the way of the adoption
of a universal standard. It is no objection to this
proposal to say that the people of each nation are in-
capable of pronouncing certain sounds. This is not
true, so far as relates to the languages with which we
have practically to do. No Englishman, for instance,
if properly instructed, can fail to learn the sound of
the German ch, or the French u or eu in a short time,
and practice will then make it easy. Moreover, the
number of sounds peculiar to each nation is much
exaggerated. The French, it is said, have a dislike
to the sound of w. It would not be difficult, were
this the place for doing so, to make out a long list of
words which every Frenchman uses, in which this
sound occurs, though not the letter. Conversely, the
so-called peculiar vowel-sound of the word cueillir
has its exact counterpart in English words.
Although the time is not ripe for the adoption of
the above-mentioned scheme in its entirety, there is
one feature of it which will form a good step in ad-
vance, and which may be at once accepted. This is
the absolutely certain fact that c and g should invari-
ably have a guttural sound. I am not speaking of the
attempt to make this rule apply to English words
derived from classical roots. That is quite a distinct
subject, though it is not always kept distinct. Scien-
tific names are Latin words, and should be so pro-
nounced. The case of Geranium and the like will be
no obstacle, for it is easy to pronounce the g hard
when we speak of Geranium molle to a fellow-botanist,
and soft when we speak to a lady-friend of the
geraniums in her conservatory. This is no more than
is done every day by people who can speak more than
one language. They do not, for instance, give the
same sound to ball in English, and ball in German,
because they are spelled the same, and are names of
the same object : and similarly with the French and
English point.
With reference to the pronunciation of words
derived from names of persons and places, it will be
only consistent to insist that they shall be sounded
according to the rules of the language from which
they are taken. In so far as they are neither classical
words nor derived directly from classical sources,
HARD WICKE }S S CIENCE- G O SSIP.
there can be no reason for pronouncing them as such,
even if it were not sometimes impossible to do so. I feel
sure every botanist, meeting with one of these strange-
looking words, would rather give it the proper sound
than attempt to pronounce it according to English
rules, with a result which, he is painfully conscious,
is absurd. What is wanted, is a compendious and
handy guide to the sound of the letters in the chief
foreign tongues, such as French, German, Italian,
Swedish, etc., and even Russian. It will be found
that the sounds which do not exist in English are
very few, and plain directions can be given for the
attainment of most of those. Were such information
commonly disseminated among scientific men (and
perhaps Science-Gossip would be a good place for
it to appear in), we should cease to hear such
barbarisms as Hypniun Swartzii, with the w pro-
nounced as in English, and Veronica Buxbaiimii, with
the ait as in the English haul. It would be found,
too, that the trouble required would not be great.
Merely to learn how certain consonants and vowels
are sounded in a language, is a very different thing
from learning the language itself.

A DOMINIE'S BOTANICAL HOLIDAY.
WHAT a grand thing it is to have a holiday,
and how refreshing to live almost out of doors
for a whole month ; to wander hither and thither fancy
free, by the brookside, or amid the tangled mazes of
the wood, to ascend to the top of yonder hill, or to
find out a path for ourselves through the glen — to
climb the rock by the sea-side, or to lie on one's back
on the thyme-covered bank above ! With some
such thoughts did I awake one morning in the
summer-time of last year. My holiday I intended
this year to spend in the west of Scotland, and once
on board the Marmion, with the "guid braid"
Scotch tongue all around me, I fancied myself there
at once. The weather was beautiful, and the good
ship Marmion steamed away right merrily for the
North. As we reached Flamborough Head we had
a good view of the land, and all the way from this
point the objects of interest were noted by tourist
passengers.
All this time I am on the sea, and as I cannot do
much in a botanical way on board of a steamer, I
live in a sort of poetical dream, in which the cha-
racters in "Marmion" are all chasing each other
through my brain. At length we arrive at our
destination, and saying good-bye to the steamer,
I pay a short visit to " Auld Reekie," my Alma
Mater, and in a short time find myself en route for
the west.
On arriving at A , my botanical rambles at
length begin, and I am soon in the full enjoyment of
the pleasures I had looked forward to. Over most
of the ground I had already made excursions as a
boy. Then my pursuit savoured somewhat of orni-
thology, now in manhood's day I was a humble
student of the beauties of Flora's domain.
Several of my rambles on this occasion I shall
always remember with pleasure, and one of those in
the foremost rank would be that visit to the Carrick
country. Who does not admire the purple heather
of our Scottish hills ? Now I was able to make a
distinction between the commonest kind of all —
Ling or Calluna vulgaris, and the different kinds o
Erica which grow together on the hill-side, and a
new pleasure seemed to be mixed with my boyish
love for the "dark purple heather." The Blue-bell
{Campanula rotundifolia) is to be found gracefully
nodding its head to every little breeze, and seeming
to bring up memories of "auld lang syne," and,
although I can remember it as one of the most
delightfully common of little flowers of my boyhood,
I can also remember the words of Ellen, the " Lady
of the Lake," that—
" It drinks heaven's dew as blithe as rose
That in the king's own garden grows."
A wealth of hillside flowers is to be found around
me, such as the pretty little Eyebright and the
Creeping Cinquefoil, with its relative the common
Tormentil. Moving on a little on one side I come
across two of Our Lady's flowers — the Lady's Mantle
(Alchemilla vulgaris), and the Galium verum, or
Lady's Bedstraw, or Beadstraw. Getting into a
part where the ground is somewhat moist and boggy,
the lovely Parnassia palustris soon rivets attention.
What a splendid view from the top'of the hill ! Right
away to the Irish coast almost, on one side, and
around me I can survey the whole extent of country
where
" Bruce he shook his Carrick spear."
Another very enjoyable ramble was the one paid to
Loch Doon, the birth-place of the " bonnie Doon."
This was accomplished by going by rail to Dal-
mellington and walking to the loch. The walk by
the side of the Doon is a magnificent one, and as the
glen gets narrower and the rocks higher I am fairly
enraptured with nature's works. At length I emerge
from the glen with pleasant thoughts of the beauty of
the ferns and mosses which I have seen peeping out
from the crevices of the rocks and adorning every
spot of vantage. Keeping company with the Crypto-
gamia I had also observed quantities of that pretty
saxifrage the London Pride, or " None-so-pretty,'"
and the Crow Garlic, with its beautiful star-like
blossoms, and its leaves somewhat resembling those
of the Lily of the Valley. Having got safely through
the glen, I find myself on the borders of a wild high-
land lake, studded here and there with islets. Being
desirous to change the walk, I reach Dalmellington
by a different route, and as I have to pass through
many acres of bog-land, my old friend the Parnassia,
B 2

fialnstris is found in great plenty. The Ericas also
look well, and I am constrained to gather some of
them. I also find the Milkwort, or Rogation
flower, in great plenty and very various in its hues.
Dalmellington is at length reached after a long
ramble, and I am glad of a little rest after my
labours.
The flowers on the Ayrshire coast are very
numerous, and an excursion for the purpose may be
made with advantage by any one who may be

interested in wild flowers. The Sea Convolvulus
and the Rest Harrow, with the Scurvy Grass and the
Eryngo Maritimum, may be found here in great
plenty, besides hundreds of other well-known plants.
A great many varieties of the most beautiful of the
Alga: may be gathered on the sea-shore after a
storm.
After spending about a fortnight on the mainland
I determine to make the Isle of Arran, in the Firth of
Clyde, the scene of my operations for the remaining
part of the time. Crossing one morning from
Ardrossan in a little steamer, I arrive at Brodick,
and at once start for a walk across the island.
Having got right to the other side I proceed to
arrange about a lodging, and as I am out of the way
of all bustle I make up my mind to enjoy myself.
I could soon see that 1 was looked at, as I thought,
with some degree of patronage by the natives. In order
to encourage me several hoary islanders used to

appear with immense bundles of weeds round the
cottage where I lodged, about eventide. As the
evenings were fine I used to take a chair out uf
doors and hold a sort of reception. It was to me
very amusing to observe the specious pretexts by
which these "ancient mariners" used to lure one
to talk when they found that I could tell them
about London ; and how desirous they were to
know all about it. Almost every evening I might

expect one or more of my friends coming to visit
me, and to hear something more about the "big
ceety." In the daytime I enjoyed my rambles
exceedingly, and I came across many specimens
here that I had not seen for some time. The
lovely Alpine Lady's Mantle repaid a climb up one
of the hills, and in the boglands below I found the
Drosera rotundifolia, and its usual companion the
longifolia. Another carnivorous little plant which
is often a near neighbour, one of the Butterworts,
Fig. 3. Purple Loosestrife (Lythrum Salkaria).
I also found in
part of the bog
the same neighbourhood. One
I found quite covered with the
Cotton Grass, and close by a great deal of the
Marsh Cinquefoil, which, although it has done
flowering, I am able to make out by its strawberry-
looking seeds. Another part of the bog I find
covered for a great distance by the Horsetail
(Equisetitm), and in the running stream by the side,
its representative the Hippunis. The Bog Bean is
also present with its tripartite leaf, but it is now
destitute of flowers, and in close proximity is the
Marsh Valerian. Before leaving the moist ground
I feel called upon t o admire the beauty of a large patch
of the Purple Loosestrife, which has a grand effect.
It was after one of my excursions, and whilst I was
holding my usual evening " confab " with my friends,
that one of them confided to me that ' ' a wee drap
o' Luckie Findlay's whusky wad be a guid thing
to carry wi' ane oot on tha hills." I told him that
it might or it might not, but as I did not want it
for the purpose of quenching thirst it would be a
useless encumbrance. I saw that Donald looked
quite astonished at my te merity to venture to speak
slightingly of what was to him, no doubt, a sove-
reign remedy for everything whatever.
It was only a day or two after this that I took
my farewell ramble in Arran. It was not the best
of days, and the weather seemed to be breaking up.
As my holidays were now drawing to a close, I was
not so much concerned on the subject. In this,
my last excursion, I came upon the Osmunda regalis
in a boggy piece of ground. It was growing up in
several clumps, and looked very well indeed. After
this I also came across the Sweet Gale, or Bog
Myrtle. It was about here in great profusion, and
smelt very strongly of the myrtle-scent belonging
to it. A little farther on amongst the Sheep's-bit
Scations and the heather, both purple and white,
I found for the first time the pretty Bog, or Lan-

TAME BEARS IN SWEDEN.
By John Wager.
IT is well known that the Bear, by a course ot
severe discipline, can be taught to carry a long
pole in his paws or a pert monkey upon his back, to
dance to the music of pipe and drum, and to perform
tricks which the solemn gravity of his demeanour,
his clumsy motions, and shaggy hide, render the more
amusingly grotesque. He may also be seen, in the
den of a 'menagerie, to leap through a comparatively
small ring encircled with flame, associated, during
the performance only, with leopards and a hyaena ;
though the uncouthness and reluctance with which he
accomplishes the feat, contrasted with the graceful
and ready spring of the leopards, is enough to make
the hyaena laugh ; while, of all the performers, he has
evidently the most intractable temper, and is least
trusted by the spangled damsel who presides with
the whip.
HARD WICKE 'S S CIENCE - G OSSIP.
Yet, when young, the Bear is not altogether devoid
of amiable qualities, as the following narrative will
prove. The account was communicated to the present
writer in 1867 by a Swedish acquaintance residing at
Mora, in Dalecarlia, the bear being then living, and
the property of a gentleman at Siknas, in Venjan, an
adjoining parish, having been taken when about three
weeks old from the adjacent forest in February, 1865.
Being fed with warm milk, young Bruin throve
satisfactorily, and when large enough to enjoy liberty
he usually sojourned in the yard with the bear-dog
" Jeppe," playing and springing about his companion
like a cat. He was also much attached to his master,
delighting to accompany him not only to the forest,
where he often clambered up trees, but also into the
house, where removing chairs and tables from one
room into another appeared to be his favourite oc-
cupation. Strangers who visited Siknas always
received his attentions ; but as these were somewhat
brusque, and expressed in a surly tone, they tended
rather to repel than attract.
To Swedish punch (a luscious compound of arrack
and sugar) he was extremely partial, and partook of
it, whenever invited, out of a glass, like a well-bred
gentleman, but afterwards showing his loutish and
lumpish nature in a drunken fit, concluding with
heavy sleep and loud snores.
One day, while Bruin was yet of tender years, a
kitten came into the yard and immediately drew his
surprised attention upon herself; but young Puss, not
admiring his looks, first cast upon him an angry glance,
and then sprang up and fixed her claws in his head,
exciting such alarm that he trotted off in a nervous
perspiration, and ensconced himself in an outhouse.
Subsequently he always fled at the sight of this cat,
though she was the only one of which he showed fear.
Bruin took a daily bath in the river, which flows
within a stone-throw of the house ; swimming across
and back again. He then trotted to an ice-cellar, the
roof of which was easily accessible and covered with
deal boards, one of which projected considerably
beyond the rest ; towards the end of this he used to
ci"eep warily, to enjoy the swinging motion that
resulted. It was a mode of recreation of which he
frequently availed himself.
Whenever he could intrude into the kitchen he
bemeaned himself like an officious and meddlesome
husband, disordering affairs, greatly to the vexation
of the domestics, to whose castigations with a stout
knob stick he payed little regard. One day he laid
hold of a coffee-pan that stood on the hearth, and was
conveying it in his paws to the yard, when the hot
contents, overflowing on his bosom, provoked him to
cast it on the ground and flatten it with a stroke of
his paw. He would also, when opportunity occurred,
smuggle himself into the larder (a detached building),
looking round first to see that he was not observed,
then bring out some article, especially a cheese, which
he found convenient to carry ; but on one occasion he
made free with a tub of clouted milk and cream,
handling it, however, so awkwardly that the ropy
tenacious contents streamed down the front of his
erected corpus, and, as in the case of the coffee-pan,
brought vengeance on the tub. After fruitless en-
deavours, with tongue and claws, to clear the viscous
mass from his best fur coat, he betook himself to the
river, and then solaced himself with a swing.
This partiality for swinging or rocking rendered
him an undesirable companion in a boat ; yet he
constantly followed his owner to the river-side, and if
not admitted as a passenger, would swim after the
boat, grunting like a hog. During one river excur-
sion which he had been allowed to share he enjoyed
as usual his rocking, till the boat, gliding down the
river, entered a stormy rapid, when he became quite
agitated with fear, trembling in every limb and hold-
ing on each side of the boat so long as it remained in
the weltering force. When indulged with a ride by
land, he would sometimes leap on the shafts of the.
vehicle, and placing a hind leg on each, rest his fore
paws on the horse's back.
As he grew older it was found necessary to impose
some check upon his movements, and for this purpose
a chain, with a log at the end of it, was attached to a
collar round his neck. Such badge of servitude and
interference with the liberty of a free-born bear was-
not to be borne. At first he tried to strike off the
log with his paws ; then he dragged it to the river,
but was vastly irritated to find that after every attempt
to sink it, the audacious log came to the surface again.
Finally he dug a hole, put the log into it, and re-
placed the earth, stamping or pressing it down ; then
apparently satisfied with his work he attempted to
move off, but found himself in a worse fix than before;
however, after sundry curvets and angry jerks the
chain broke and he regained his freedom, leaving his
encumbrance in the grave.
In concluding his ursine anecdotes my Swedish
friend remarked : ' ' These are but a few of Bruin's
traits and droll tricks, which must be seen to be fully
enjoyed. At present he lies quietly in his winter lair,
but imagine his humour when he leaves it in spring ;
he is then no agreeable companion, especially for the
kitchen-maids, towards whom, and the fair sex in
general, he shows the greatest disregard."
Poor Bruin ! he must indeed have got up on the
wrong side of the bed, for he became so unbearably
troublesome and subject to such angry moods, that,
as I afterwards learned, at the early age of about
three years he was doomed to death, and executed
accordingly.
Another young bear, captured in the winter of
1869, was kept for about two years at Eksharad, in
Wermland ; but as it grew older it became danger-
ously ferocious, and, consequently, was also shot. A
tame bear, kept at Sno-an, had accidentally one
Saturday evening got locked up in the smithy, and
not liking to remain in a workshop on a Sunday,
HARDWICKE'S SCIENCE -G0SS1 P.
attempted to escape through an opening in the roof.
But to reach this Bruin had to clamber upon a lever,
which, under the pressure of his weight, opened the
sluice-gate, and, turning the water upon the wheel,
set the great hammer to work. Evidently annoyed
by its persistent motion and noise, he appears to have
grasped the hammer in his paws with intent to stop
it; but the contest proved beyond his strength, for
the neighbours, hearing loud roars, hastened to the
smithy and found him lying upon the anvil, having
received a death-blow before their arrival.
THE SEALS AND WHALES OF THE
BRITISH SEAS.
Part VI.
By Thomas Southwell, F.Z.S., &c.
WE now come to the second sub- order into
which the Cetacea are divided, namely, the
Odontoceti, or Toothed Whales. In this section, baleen
is never present, but well-developed teeth are found
in one or both jaws of the adult ; in some species
they are very numerous ; sometimes, though rarely,
deciduous. The blow-hole is single, and the skull
generally asymmetrical, or not precisely alike on both
sides of the medial line. Professor Flower divides
the Odontoceti into three families, one of which, the
Blatunistidm, as already said, is found only in
India and South America ; the other two, Physe-
terids and Delphinidce, are represented in our Fauna
by about fifteen species.
Of the Physeteridcc, four genera are represented
in the British Fauna by five species ; namely, one
Physcter, the Sperm Whale ; two Hypcroodons, the
common Beaked Whale, and a very rare species
called the Broad-fronted Beaked Whale ; one Ziphius,
Cuvier's Whale ; and one Mesoplodou, Sowerby's
Whale.
By far the most interesting species is the Sperm
Whale, Physcter viacrocephalus (Linnaeus), which
rivals the Right-whale in commercial importance and
in the value of its products. This species has a very
wide geographical range, having been found in almost
every sea between lat. 60° north and 60° south. The
attempt has been made, I think unsuccessfully, to
show that the Sperm Whale of the southern hemi-
sphere is distinct from that of the northern ; there
seems, however, no reason to doubt at present, al-
though, of course, it may eventually be found other-
wise, that the same species of Sperm Whale ranges
• over the whole of this vast tract of ocean. North of
about 400 it appears to be only a straggler, and
although the Arctic seas are almost always stated by
-authors to be its head-quarters, no well-authenticated
instance of its occurrence farther north than Scotland
is on record, and Lilljeborg excludes it from his
-account of the Scandinavian cetacea. Of its occur-
rence on the British coast there are numerous in-
stances; in all cases, however, they are believed by
Andrew Murray to have been stragglers, " which
have rounded Cape Horn (they have never been
known to double the Cape of Good Hope) or un-
promising colonies, for they are becoming scarcer and
scarcer in more than their due proportion."* Of the
numerous occurrences on the coast of the British
isles I shall confine myself to a few early records.
In the church of St. Nicholas, at Great Yarmouth,
is the basal portion of a skull of this animal, which
has been converted into a chair : it formerly stood
outside the church, and of course, as it was an object
of wonder, it was relegated to the powers of dark-
ness, and christened (?) the "Devil's Seat"; it
has, however, now been admitted into mother church,
and stands beside the north-west door under the
clock. Mr. C. J. Palmer tells me that in the church-
wardens' accounts for 1606 there is a charge of 8s.
for painting this chair, which clearly proves its an-
tiquity. Sir Hamon L'Estrange, in a letter to Sir
Thomas Browne (Wilkins's edit., 1852, editor's pre-
face to " Pseudodoxia," vol. i. p. lxxxi.), says that
in June, 1626, a whale, afterwards referred to by
Sir T. Browne as a sperm whale (vol. iii. p. 324),
was cast upon his shore or sea-liberty, " sometyme
parcel of the possessions of the Abbey of Ramsey,
&c." The same author, in his account of the " Fishes
found in Norfolk and on the Coast," says, "A Sper-
maceti whale of 62 feet long [came on shore] near
Wells, another of the same kind twenty years before
at Hunstanton [the one referred to by Sir H. L'Es-
trange] ; and not far off, eight or nine came ashore,
and two had young ones after they were forsaken
by the water." The whale mentioned by Sir H.
L'Estrange came on shore in 1626 : twenty years
after would give 1646 as the date of the Wells
specimen ; and in December of that year, according
to Booth's " History of Norfolk," published in 178 1
(vol. ix. p. 33), "A great whale was cast on the
shore here [at Holme-next-the-Sea], the wind blow-
ing strongly at the north-west, 57 feet long, the
breadth of the nose-end eight feet, from nose-end to
the eye 154 feet ; the eyes about the same bigness as
those of an ox, the lower chap closed and shut about
four feet short of the upper ; this lower chap narrow
towards the end, and therein were 46 teeth like
the tusks of an elephant ; the upper one had no
teeth, but sockets of bones to receive the teeth : two
small fins only, one on each side, and a short small
fin on the back ; it was a male . . . . ; the breadth
of the tail, from one outward tip to the other, was
13! feet. The profit made of it was £2.1']. 6s. 7d.,
and the charge in cutting it up and managing it came
to ;£ioo or more." It seems probable that a
"school" got bewildered in the shallow waters of
the Wash, and that the individual of which Booth

Murray, 1866, p. 211.

gives such an excellent description, formed one of
the same party as the eight or nine mentioned by Sir
T. Browne. In May, 1652, Mr. Arthur Bacon
writes to Sir T. Browne about the sperm whale cast
on shore at Yarmouth, but the actual date of the
occurrence is not given. This is the last record of
this species being found on the Norfolk coast, with
which I am acquainted : it has, however, occurred
many times since, singly or in small parties, on other
parts of the coast ; the last instance, I believe, being
in July, 1871, when one was stranded on the shore
of the Isle of Skye. Of the osteology of the Sperm
Whale, Professor Flower has given an exhaustive
account in a paper published in the " Transactions
very remarkable appearance, the truncated form of
the snout looking as though it were cut off at right-
angles to the body : at the upper angle is situated the
single blow-hole. The juncture of the head with the
body is the thickest portion, and the body decreases
little in size till the "hump," which is situated in the
place of the dorsal fin, is reached ; from this point
it rapidly diminishes to the tail. The flukes of the
tail are from twelve to fourteen feet in breadth, and
the two flippers each about six feet long. The under
jaw is pointed, and about two feet shorter than the
upper ; it is furnished with about twenty-five large
conical teeth on each side ; but the number is not
constant, nor is it always the same on each side. In
Fig. 4. Sperm Whale (Physeter macrocephaltis, Linn.)-
of the Zoological Society," vol. vi., and of its habits
a very interesting account is given by Thomas Beals,
who, in the capacity of surgeon on board ships
employed in the South Sea fishery, had unusual
opportunities of observing this remarkable animal.
He published a book entitled " The Natural History
of the Sperm Whale," to which I am largely indebted
for what I shall have to say about this species.
The colour of the Sperm Whale is black above and
grey beneath, the colours gradually shading into each
other. The full-grown male is about sixty feet
long ; the females are much smaller and more slender
than the males. The head, which constitutes more
than one-third of the whole of the animal, presents a
the upper jaw are no visible teeth, but those of the
lower jaw shut into corresponding depressions in the
upper. The tongue is small, and, like the lining of
the mouth, of a white colour. The upper part of the
head, called the "case," contains the "spermaceti,"
which upon the death of the animal granulates into
a yellowish substance. Beals says that a large whale
not unfrequently contains a ton of spermaceti. Be-
neath the "case" is situated the "junk," which
consists of a dense cellular mass, containing oil and
spermaceti. The blubber is about fourteen inches
thick on the breast, and in most other parts of the
body from eight to eleven inches. By the whalers
this covering is called the " blanket." With regard
HARDWI CKE 'S S CIENCE - G O SSI P.
to the apparently ungainly head of the Sperm Whale,
Beals remarks as follows : — " One of the peculiarities
of the Sperm Whale, which strikes at first sight every
beholder, is the apparently disproportionate and un-
wieldy bulk of the head ; but this peculiarity, instead
of being, as might be supposed, an impediment to the
freedom of the animal's motion in its native element,
is, in fact, on the contrary, in some respects, very
conducive to its lightness and agility, if such a term
can with propriety be applied to such an enormous
creature ; for a great part of the bulk of the head is
made up of a thin membranous case, containing,
during life, a thin oil, of much less specific gravity
than water, below which is again the junk, which,
although heavier than the spermaceti, is still lighter
than the element in which the whale moves ; conse-
quently the head, taken as a whole, is lighter specifi-
cally than any other part of the body, and will always
have a tendency to rise at least so far above the sur-
face as to elevate the nostril or ' blow-hole ' suffi-
ciently for all purposes of respiration ; and more than
this, a very slight effort on the part of the fish would
only be necessary to raise the whole of the anterior
flat surface of the nose out of the water. In case the
animal should wish to increase his speed to the ut-
most, the narrow inferior surface, which has been
before stated to bear some resemblance to the cut-
water of a ship, and which would, in fact, answer the
same purpose to the whale, would be the only part
exposed to the pressure of the water in front, enabling
him thus to pass with the greatest celerity and ease
through the boundless track of his wide domain "
(p. 28). When swimming at ease, the Sperm Whale
keeps just below the surface of the water, and goes
at about three or four miles an hour ; but on an
emergency it is able to attain a speed of ten or
twelve miles an hour : it then progresses by means
of powerful lateral strokes of its tail, and alter-
nately rises and sinks at each stroke. In progress-
ing in this manner, the blunt anterior surface of
the head never presents itself directly to the water ;
the animal's body being in an oblique position, it is
only the angle formed by the inferior surface which
first presents itself, and this, which Beals likens to the
" cutwater " of a ship, offers the least possible amount
of resistance. When undisturbed, the Sperm Whale
rises to the surface to breathe about once every hour.
Beals says the regularity with which every action
connected with its breathing is performed is remark-
able ; the time occupied differs slightly in each indi-
vidual, but each one is minutely regular in the per-
formance of every action connected with respiration,
so that the whalers know how long it will remain
beneath the surface before reappearing to renew its
supply of air. A full-grown ' ' bull, " he says, remains
at the surface ten or eleven minutes, during which he
makes sixty or seventy expirations ; after which he
disappears, to return again to the surface in one hour
and ten minutes. The blowing is not accompanied
by any sound, and notwithstanding the wonderful
accounts of its roarings and bellowings, the Sperm
Whale may be said to be an absolutely silent animal.
The females and young males are gregarious, but are
found in separate herds or "schools," as they are
called. A " school " will sometimes consist of five or
six hundred individuals. The herds of females are
always accompanied by from one to three large
"bulls"; but the full-grown males are said to be
generally solitary in their habits, except on certain
occasions, when it is supposed they are migrating
from one feeding-place to another. The majority of
those which occur on our coast are these solitary
males ; when they visit us in herds, as mentioned by
Sir Thomas Browne, they are all probably females
or young males. The "bulls" are veiy fierce and
jealous, and fight fiercely. The females show great
attachment to each other and to their young, so much
so that, one being wounded, the others of the herd
remain and fall a comparatively easy prey. The
young males, on the other hand, are very wary and
difficult of approach, and should one be attacked, the
others immediately take the alarm and retreat . The
female produces one young one, rarely two, at a time,
and breeds at all seasons of the year. Their senses
of sight and hearing are very acute, and after being
once unsuccessfully attacked, they are very difficult
and dangerous to approach.
The food of the Sperm Whale consists almost en-
tirely of Cephalopode Mollnsks (cuttle-fish), although
at times, when feeding near the shore, it has been
known to take fish as large as salmon. It is, how-
ever, essentially a deep-water species, but how it con-
trives to capture such active prey as fish seems difficult
to conceive. Beals is, however, of opinion that the
Whale sinks to a proper depth in the sea, where re-
maining as quiet as possible, and opening wide its
mouth, the prey are attracted by the glistening white
colour of its lining membrane, curiosity leading them
to destruction ; for no sooner have a sufficient number
entered his mouth than the Whale, rapidly closing his
under jaw, they are made prisoners and swallowed.

THE HISTORY OF SALAD PLANTS.
By H. G. Glasspoole.
CRESSES.
CRESS is a general name of a number of plants,
mostly, if not all, belonging to the Cntciferce,
and possessing, in common with the plants of the same
order, pungent and aromatic qualities. The ancients,
we are told, ate cresses with their salads to counter-
act the cold nature of lettuces and other herbs.
The garden cress, Lepidinm sativum, appears to
have been known to Theophrastus (see article in
Rees's "Encyclopaedia"), but the tribe of Nasturtium,
to which the Water-cress belongs, was, no doubt,
IO
HA RD WICKE 'S S CIENCE - G 0 SSIP.
most common in use. The Greeks thought that the
warm and stimulating qualities of these plants put
life and energy into persons with a sluggish tempera-
ment, and also brightened the understanding of those
who partook of them : this circumstance gave rise to
the Greek proverb, " Eat cress and learn more wit."
Xenophon recommended the Persians to feed their
children with cresses, which he said would make
them grow tall, and be of more active habits. Pliny
dwells much on the medicinal virtues of these plants,
and recommends them to be eaten with vinegar as a
remedy for those minds that were deranged. The
garden cress is said to have been introduced into this
country about the middle of the sixteenth century.
Gerard mentions having received the seed of the
curled cress, which is a variety, from his loving friend
John Robins, of Paris. Thomas Cogan, in his
"Haven of Health," tells us "that the often eating
of this herb in salettes doth give sharpnesse and
readinesse to wit." The native country of this plant
was unknown until Dr. Sibthorp discovered it in
Greece.
No British plant is in such popular request for
salad as the Water-cress, Nasturtium officinale, the
young leaves of which are supposed, like those of the
Scurvy-grass {Cochlearia officinalis), to purify the
blood, and therefore largely partaken of in the
spring. Our old friend Gerard recommends young
ladies to eat them as a restorative to the natural
bloom of their faded cheeks. A decoction of its
juice with that of Scurvy-grass and Seville oranges
used to be given to children as a medicinal drink in
the spring in days gone by. In Europe the water-
cress appears to have been first cultivated at Erfurth,
about the middle of the sixteenth century, but it was
not until 180S that it became an object of cultivation
in England. About that period a Mr. Bradbery began
to grow them for the London markets in the pretty
valley called Springhead, Northfleet, Kent, with
great success. In 1820 he removed to West Hyde,
near Rickmansworth, where he had no less than five
acres under water-cress cultivation. It is now ex-
tensively grown in the northern and eastern suburbs of
the metropolis, and also at Cookham, Farringdon, and
other places on the Great Western Railway, which line
brings no less than a ton a week of this wholesome
breakfast salad to London. Many hundred bunches
are sold every morning in Covent Garden, but the
largest share goes to Farringdon Market. The en-
tire supply to the various Metropolitan markets
cannot be less than from three to four tons per week
(see Wynter's "Curiosities of Civilization"). The
sale of this plant forms an important though humble
branch of domestic commerce in our towns and
cities. " Fine fresh Water-cresses ! " is the first coster
cry heard in a morning in the streets of London.
Water-cress contains chloride of potassium and
sulphur in considerable quantities, and iodine occa-
sionally.
The botanical name of the garden-cress, Lepidium,
is derived from lepis, a scale, from the form of the
seed-pouches ; that of Nasturtium, from nasus, nose,
tortus, torment, from the effects most of this genera
have upon the muscles of the nose,— a name given to
it by Pliny. In some counties these plants used to be
called ' ' Nose-smart " for the same reason. The word
" cress," perhaps, may be derived from cresco, being a
quick grower. In the last edition of the " English
Botany " we are told that the word "cress" is found in
various forms in all Teutonic languages. Some have
derived it from the cross form of the flowers.
Chaucer employs the Saxon form of the word Kers,
to signify anything worthless : —
" Of paramours ne raught he not a Kers ; "
from which, perhaps, is derived the phrase of not
caring a curse for anything.
THE ANNELID "DERO."
By R. Garner, F.L.S., &c.
'"pHE two little fresh- water Annelids, portions of
J. which are figured at a, b, c, are very dis-
tinct from their allies, the Naids. of which, however,
several species are often found with them ; Nais
proboscidea, for instance. Dero is the generic name
appropriated to the present annelids. Though hardy,
they seem to require a warm temperature, and those
here described inhabit the slimy mud of a pool, into
which hot water is constantly pouring from an engine.
A dark green Oscillatoria also grows in the same
mud, and thrives in a higher temperature than either
the annelid or the hand can endure.
The peculiarity of Dero, and one which makes it a
pretty object for the microscopist, is the expanded
membrane or respiratory disk, situated at the posterior
part of the body, having projections or processes
upon it, and the whole strongly ciliated, thus pre-
senting some resemblance to the corona of a Bryozoon,
though the ciliated processes are fewer. This part,
the undoubted respiratory organ, it is the habit of the
little animal to protrude out of the mud in which it
lives, and when the disk is expanded, the processes
fairly extended, and the cilia in strong action, few
objects are more striking. There is a difference
between a and b and c, the former having a pair of
antenna-like processes, which are not retractile.
Another interesting point, and one which from the
transparency of the animal and the bright-red colour
of the blood, is not difficult to investigate, is the
circulation. Of this, investigation has already been
made,* and all that we give here is solely what we
have ourselves noticed. An abdominal vein running
from the head, /, to the respiratory disk at the
opposite extremity, a, receives the blood from the

head, and from what may be termed a vascular rete
mirabile enveloping the stomach and intestine, and is
divided behind, g, and distributed to the branchial
processes. From these, vessels again converge into
a dorsal artery, following the undulations of the
alimentary canal, and conspicuous from an intrinsic
portions, two as above and a third behind, and
the somites in the last portion have evidently been
most recently formed.
A double abdominal nervous cord is plain enough
all along below the longitudinal vein ; the brain is
less definitely seen ; there are also two minute bodies

metility which the vein has not. The course of the
dorsal vessel is somewhat the same as the ventral.
When it lies above the middle part of the alimentary
canal it forms the beautiful network already men-
tioned, and is, besides, connected in each somite or
section of the body with large contractile loops,
apparently distributing the blood to the viscera and
parietes of the body, but, according to Perrier, not
immediately connecting the two vessels. The little
worm is well supplied with abdominal tufts of sigma-
shaped hooks for crawling, and also with lateral or
dorsal seta? for swimming, the former are bifid at their
extremes, e.
The mouth, d and f, is furnished with a bulbous
tongue, which can be protruded a little in feeding ;
both here and behind the alimentary canal is ciliated ;
there is some appearance of a stomach at about the
seventh and eighth somite of the body, and here is
the liver incorporated with the canal, and also
in the same region the ovaries, &c. ; the intestine is
dilated in each division of the body, and connected
by bands with its parietes.
We have no sufficiently matured observations to
offer as to the development of the ova in the Dero.
Perrier describes its fissiparous mode of increase, but
the following account differs somewhat from him.
Sometimes a long Dero, say of fifty joints, very
evidently divides into two, a respiratory disk for the
anterior secondary worm, and a head for the posterior
one being formed at the place of disjunction ; here
the anterior portion, containing the ovaries, probably
becomes the germ-mother, and perhaps winter-nurse.
In other cases the individual Dero presents three
at the sides of the brain, probably acoustic, a few
darker coloured spots more forward, and apparently
lateral oral ganglia. The animal is sensitive to a
very slight concussion of the vessel in which it lives.
PLANT-HUNTING AT BARMOUTH.
By J. Percival.
HAVING read with great pleasure the interest-
ing notes of your correspondent Horace
Pearce, F.L.S., of the flora of the neighbour-
hood of Cader Idris, I wish to add, by way of
supplement, a few of the plants that came under my
observation during the summer of 1876, for I find
that he has omitted a great portion of the rarer
species. Walking along the road in the direction of
Llanaber may be seen Parietaria officinalis, Eckium
vidgare, Clinopodium vidgare, Origanum vidgare,
Eaonymus Europazts, and Aspleninm lanceolatum.
This latter plant may be found for a mile on old walls
and rocks, and in far greater abundance than its near
ally, Aspleninm Adianlum-nigrum. It may also be
found on walls overlooking Barmouth, and also for
two miles on the Dolgelly road from Barmouth;
turning into the harbour, a little short of a mile from
Barmouth, it may be seen there very fine and abun-
dant. A little further, on rocks facing the sea, may
be gathered Rubia peregrina, or the common Mad-
der ; growing also with it is Inula conyza, or the
" Ploughman's Spikenard " ; another mile further on
brings you to Carex extensa and Tamarix Gallica ;
and also Spircca salicifolia : both the latter have, no
doubt, been planted, but probably they are as wild

on, until coming to a large stream, going up the hill
side, may be found Carex binervis, C. laevigata, and C.
fulva, the latter in the greatest plenty. Gnaphaiium
dioicum, Scutellaria minor, almost in all swampy places,
along with Drostra rotundifolia. Up this valley, t
picked up of the Drosera an immense number of
sports, varying from one to six and seven stems from
the same root ; others branched into several divisions
at the top of the stem : I picked up about twenty of
them, and scarcely two alike. Crossing over the

mouth and at Friog. Along the coast may be
gathered Crithmum maritimum ; amongst loose
stones in several places, and also very fine, two feet
in height, on rocks exactly behind the pay-house. In
crossing the bridge, Polygonum Raii, Sclerochloa loliacea
and rigida. On the railway banks, about 400 yards
from the station, grows Mentha rotundifolia , and in
grassy flats, running parallel with the railway at this
place, there are large quantities of Juncus acutus and
maritiimis. On Sept. 5th, 1 876, I saw hundreds of
Pellitory of the Wall [Parietaria officinalis)
hill from this point (say a mile up the valley) in the
direction of Barmouth, my friend Mr. Roger,
gathered a plant of Onobrychis saliva. On the hill-
side overlooking Barmouth may be found Geranium
sanguineum, Dianthus delloides, and Orobanche
major ; and on an old wall nearly opposite the Corsy-
geddol Hotel may be gathered Orobanche Heditue ;
whilst on the rocks in the direction of Llanabers
near the toll-gate, may be found Veronica hybrida.
Proceeding along the high road for a mile may be
found, in the greatest abundance, Lathy rus sylvestris ;

Crossing over the estuary, and getting on to the
bog at Barmouth Junction, may be found Phragmites

than six feet. I have a specimen not 20 inches high,
with roots and four perfect panicles ; growing along
with it is CEuant/ie erocata, Scirpus maritimus, and
Typha latifolia. The last-mentioned plants grow in
the sluice by the railway-side, until one gets beyond
Penman Pool Station from Barmouth. At the Bar-

the salt marshes, may be found Statice Limotiium and
S. rariflora, also Sueda mariiima and Saticornia in
the greatest abundance. CEnanthe Lachenalii and
Apium gravelens both grow near Penman Pool Sta-
tion, and, retracing my steps to the rocks, near
Friog, growing in inaccessible situations, may be
seen Asplaiium marinum ; and following the
coast to the next village, Llangrwyen, near the
station, I have found Mentha viridis, M. piperata,

By the road, in woods, are large quantities of Hyperi-

MICROSCOPY,
An easily-made Cell. — The " American Journal
ol Microscopy " gives the following excellent recipe
for constructing cells: — "A cell which we have
found very durable, easily and quickly made, and
very neat, is constructed as follows : Having pro-
cured some good gold size and pure litharge, grind
the latter to a very fine powder. Mix the litharge
and gold size to the thickness of cream, and colour
either black or dark olive by adding lamp-black.
With this paint, as it may be called, make as many
cells as are wanted, and when made, dust finely-
powdered litharge over them until they are covered
a sixteenth of an inch deep ; allow them to stand a
few minutes, and then shake off all the loose litharge
by means of a few smart taps. The surface of the

cell will now be quite rough. Allow it to stand a
few hours, and then press it against a plate of glass.
If this be done carefully, a smooth, solid ring will
be left on the slide. If the edges should not be as
smooth as they ought to be, it is easy to trim them
off on the turntable by means of a small chisel.
Such cells, after a few weeks, become very hard, and
may be finished so as to be very neat. For dry
objects they leave nothing to be desired, and as we
have had them in use for over five years, we can
speak as to their durability. For objects mounted
in liquids it will be necessary to coat them with
suitable varnish. Thus, for saline liquids, a coating
of gold size renders them perfectly impervious. For
glycerine use Bell's cement, or a solution of shellac in
alcohol."

The Monthly Microscopical Journal.— We
have received a copy of the November and December
number of this well-known journal, containing a
very brief account of the death of the late Editor
(Dr. Lawson), and a notice that the present number
is the last of the series, and that henceforth the
Royal Microscopical Society intend to publish their
own Transactions, after the manner of the other
learned societies.
The " Spontaneous Generation " Contro-
versy.— At a recent meeting of the Royal Society,
Professor Tyndall referred to some hermetically-
sealed flasks opened on the Alps, which, he thought,
set this controversy at rest. Professor Tyndall
stated that he took with him last summer to the
Alps sixty hermetically-sealed flasks, containing
infusions of beef, mutton, turnip, and cucumber,
which had been boiled for five minutes, and her-
metically sealed whilst boiling was going on. The
flasks were kept for six weeks and were then
opened, some in haylofts and others near precipices.
The two groups of flasks were then placed in a
kitchen, where the temperature was from 650 to
90° Fahr. The result was that twenty-one out of
the twenty-three flasks opened in the hayloft were
filled with organisms, whilst all the flasks opened
near the edges of precipices remained as clear as
distilled water !
Sph/ERAPHIDES. — I have found the following
a very simple and efficient method for procuring
sphceraphides from rhubarb when not required to be
viewed in situ: — I take a piece of rhubarb and
separate the fibres into several small pieces, length-
wise, then allow them to remain for a few days until
moderately dry. If rubbed together over a sheet of
note-paper, the matter thus obtained may be collected
on a slide : it will be found to consist principally of
detached spharaphides. The few particles of fibre
may be easily removed with a camel-hair pencil.
They can then be mounted, when dry, as opaque
objects or in Canada balsam, as required. — W. H.
Harris.
Birth of Vinegar Eels. — While occupied, a
few evenings since, with the microscope, examining
an eel from some vinegar, I was the fortunate witness
of an interesting event. I had, by the cap of the
live box, caused a sufficient amount of pressure to
keep the worm still, when a segment, about the
centre one, ruptured and allowed the egress of a
twin. The pair were, in all respects but size, pre-
cisely similar to their parent. I do not find any men-
tion of the like occurrence in Dr. Carpenter's very
excellent and interesting work, "The Microscope,"
very little being written about Anguillulce aceti in the
chapter devoted to Ar.mdosa. — IV. H. S.
The late Dr. Beatty. — We are sorry to notice
the death of Dr. Beatty, of Baltimore, at the early
age of 40 years. Dr. Beatty was a valued contributor
to our pages, and microscopists are under a debt of
gratitude to him for the elaborate articles he pub-
lished in these columns on " Decolouring and Stain-
ing Vegetable Tissues."
Cleaning Slides. — I have seen very frequently
in different books, plans, troublesome and awkward,
for cleaning the balsam off slides. Why do not people
just wash them with rectified naphtha? The balsam
is removed instantly. The hardest and oldest, when
thick, only requires the naphtha to be warm ; but all
that can be should be scraped off first. In this way
it is the easiest thing possible. I have used it for
slides and lenses for many years. — Edward Thos.
Scott.
To Clean Old Slides. — The following has been
my plan for years, and is simple, easy, and effica-
cious : — Warm the slide over a spirit-lamp to remove
the covering glass which, place in a water-glass with
benzole. Scrape off as much as you can of the bal-
sam, or whatever it may be, from the slide, and
wash zvith benzole, and use an old silk pocket handker-
chief, which I dip into the benzole, a very little
of which is sufficient. — John Bramhall.
To Preserve Glass Slips ready for Use
after Cleaning. — As it is most inconvenient to
make each slip chemically clean at the time it may be
wanted for mounting a specimen, doubtless most of
your readers clean a quantity (say half a gross) at a
time ; but then probably they have often, in common
with myself, experienced the inconvenience of their
again getting dirty before they are used, through their
lying about in a drawer or on the table of the laboratory.
To obviate this difficulty, I have recently adopted a
method which is simple, and, at the same time, so
effectual, that the slips may remain for months
covered with dust and dirt, and yet be clean and
ready for use whenever they are required. It is
this : — After cleaning, the slips are arranged side by
side, with their flat surfaces in approximation, when a
ready-gummed piece of silver or tissue paper,* 10
inches long by a width which varies according to the
number of slips, is affixed to their edges in the same
fashion as the sheets of paper in a drawing-block are
joined together, so that, although they are firmly
attached to each other by their edges, their surfaces
are left uncovered. The block thus bound is left to
dry, when each slip may be detached by running the
thumb-nail round its edges. The surface next the
adjoining slip should be used for the preparation to
be mounted as it is, of course, quite clean, although
the other (or exposed one) may have become dirty ;
the fragments of tissue-paper being removed after the
mount is completed. — J. W. Groves, London.
* Any other paper is so thick that it is difficult to separate
the slips without the use of a knife.

How to Clean Thin Covers. — The difficulty
of cleaning very thin covers without breaking them
is very great. It is almost impossible to handle them
in the fingers, and when they are rubbed between
two plain blocks covered with chamois leather, it is
difficult to clean more than one side, since one par-
ticular side will always stick to the leather next it,
and the other side only will be subjected to friction.
Mr. Jones has devised a very simple method of over-
coming this difficulty. Into a brass cylinder he fits
a heavy plug, the lower end of which is covered
with chamois leather. When a thin cover is placed
on a piece of stretched chamois, and the tube placed
over it, the under side only of the cover is subjected
to friction, and consequently a few rubs suffice to
clean it thoroughly. The tube is then raised, the
cover turned over by means of a delicate pair of
forceps, and the other side is cleaned. The pressure
of the plug is so even that there is no risk of fracture,
even with the most delicate covers.
ZOOLOGY.
Dublin University Biological Association.
— We have received three parts of the first volume of
the " Proceedings " of this well-known society, con-
taining some very valuable and well-written papers,
among which are the following : — "The Leaf Struc-
ture of Begonia" and " Irish Fungi," by Greenwood
Pirn, F.L.S. ; "Some Curious Marine Forms," by
Prof. Macalister ; and " Papers on Anatomical
Irregularities," by Mr. Malet and F. O. Ross, &c.
Arctic Birds. — At a recent meeting of the Zoo-
logical Society, Mr. Henry Seebohm, F.Z.S.,
exhibited and made remarks upon some of the rarer
Eggs and Birds which he had obtained during his
recent visit to the Arctic regions of the Yen-e-sey, in
Eastern Siberia, and gave a rapid sketch of his
journey. Some of the skins were interesting from the
fact that they extended our knowledge of geographical
distribution'; such as, Phylloscopus trochilns and
Acrocephahis schccnobanns, from long. 88° E.,
Anthns Custavi of Swinhoe (A. Seedo/wii of Dresser,
A. batchianesis of Gray) from the same longitude, and
young in first plumage of this species.
The Leeds Naturalists' Society. — We have
received a copy of the Report of this Society, and
are delighted to find it in vigorous health, and with a
good programme of work before it for the forth-
coming year. May we suggest to the secretaries of
Provincial Natural History, Microscopical, and
other societies, that they should send us the names of
officers, &c, of their societies, so that our volume for
1878 may be a kind of "Science Directory," for
provincial scientific societies ?
Rose-coloured Pastor or Thrush {Turdus
rosens). — A specimen of this rare bird was obtained
[ this year in the north-west of county Donegal,
Ireland, where it was captured alive in the garden of
the Gweedore Hotel, which is situated about four
miles from the coast of the Atlantic. It unfortunately
died a few hours after its capture, whilst being
conveyed in a basket to the residence of Lord George
Hill, the owner of the hotel. This is not the first
instance of this beautiful bird being found on our
shores. Thompson, in his " Birds of Ireland," informs
us of one or two specimens being shot in the
neighbourhood of Hillsborough, county Down, some
thirty or forty years ago. Perhaps some reader of
Science-Gossip could furnish us with other instances
of its appearance, either in Ireland or England, which
may have come under his notice, and which would be
interesting to all lovers of birds. — Shelah.
Sagartia sphyrodeta. — A specimen of the
beautiful golden-disked variety of this anemone in
one of my tanks has twice undergone spontaneous
fission within about seven weeks. The original
specimen had been in my possession nearly twelve
months, and by care and regular feeding had in-
creased from about the size of a fourpenny-piece,
when fully expanded, to nearly that of a florin.
Previously to its first division, I had noticed for several
days that the base had been growing more oval in
outline, and, to my surprise, on the morning of
September 10th, I found it divided into two, right
across the centre. The severance was not quite
complete when I first discovered it, but became so in
course of a couple of hours ; the two portions dragging
themselves away from each other, until they were
about half an inch apart. The severed edges of each
gradually closed together, a suture was formed, and
in course of a few days I had two perfect anemones.
These have thriven well, fresh tentacles have been
produced, and both have increased in size, till last
week I noticed that the larger of the two, which I
suppose must be considered the parent anemone, was
again elongating its base, as if contemplating fission.
About noon of the 31st ult., I had the satisfaction of
seeing that the process had begun, and watched it at
intervals till completed. The base appeared to
separate into two lobes, which gradually dragged away
from each other, making a rent which extended
upwards, till only the mouth formed a connection
between the two. This eventually gave way, and the
fission was complete, the whole performance occupying
about five or six hours. A few acontia were thrown
out, but these were soon withdrawn, and the healing
process commenced. Two days later I was feeding
my stock, and offered food to the two halves, both
of which seized it greedily, but soon expelled it
through the partially healed rents in their columns.
I shall watch the further increase of my specimens
with great interest, as the species is one of the hardiest
and most beautiful tenants of the aquarium with
which I am acquainted. It feeds well, is almost
always expanded, thrives in a comparatively small

body of water, and the contrast between the brilliant
yellow disk and the pure white tentacles is very
pleasing. Like most other anemones, it opens best
at night, and should not be exposed to too strong a
light ; mine are kept in a north aspect, and the colour
of the disk is as brilliant as when I first had them.
The same remark applies to the highly-coloured
varieties of S. troglodytes, which are very apt to fade.
— Edward Horsnaill, Dover.
A Five-winged Butterfly. — At a recent
meeting of the Entomological Society Mr. Meldola
exhibited a five-winged specimen of the Sulphur
Butterfly {Gonopteryz rhamni), which had been taken
in Norfolk by Mr. John Woodgate. At the same
meeting Mr. H. Goss, F.L. S., showed a specimen
of the Sulphur Butterfly, in which the left wings were
those of a male, and the right those of a female.
Destroying Mites. — In reply to A. F.'s query
as to destroying mites in a cabinet of Lepidoptera,
I find the best and simplest method is to saturate a
piece of blotting-paper in chloroform (methylated is
cheapest) ; place it in the drawer infected, and close
securely, repeating the operation two or three times,
at intervals of a few hours. If the drawer be tolerably
air-tight, this will effectually destroy the mites, but it
should be carefully watched for some time afterwards,
in case of fresh mites coming into existence from
eggs> upon which the chloroform would not take
effect. Camphor should be kept in the drawers of a
cabinet, and renewed as fast as it evaporates — it will
keep mites away ; but if they are introduced with, new
specimens, or otherwise, they will exist in spite of the
camphor. All fresh acquisitions should therefore be
put in quarantine before being placed in the cabinet.
Instead of camphor, a very good recipe is, equal
parts of "oil of thyme, oil of anise, and spirit of
wine," applied as I have described for chloroform
and renewed as often as the scent goes off : it must
not be allowed to touch the lining of the drawer, as
it will stain the paper. — H. Miller, Ipswich.
The Berlin Gorilla. — Poor "Pongo," who
returned to Berlin to die, after holding his levees at
the Westminster Aquarium, has been post-mortemed
and dissected by Professor Virchow. His death was
ascertained to be due to acute inflammation of the
bowels, — the same disease which carries off young
children so rapidly. Even in his very diseases
therefore, the Gorilla claims an affinity with man !
Chameleon-like Changes in the Frog. —
The changes of colour noticed by "J. J. M." in the
frog are truly chameleon-like, and, together with
similar changes seen in fish, are brought about by
the same mechanism. The skin of these animals
contains branched and ramified cells pervaded with
fine granules of a dark-coloured pigment. Similar
cells are found in certain parts of the human eye, and
without the pigment in all parts of the body, in the
so-called "connective tissues." They can nowhere
be better seen than in the preparation of frog's web
used to show the circulation. In such an object
many cells may be seen as mere black spherical
patches, whilst others cover a larger surface and show
the branches, joining similar ones from other cells.
Now under various stimuli, applied either to the
cutaneous surface or through the eye, the branched
patches of pigment may be made to contract with the
spherical form, whilst other stimuli have the reverse
effect. Inasmuch as the cell-branches join one
another, they obviously cannot contract ; it is the
contained pigment-bearing protoplasm that shrinks
out of the branches and forms the globular mass.
Obviously, when such a change occurs in the greater
number of the cells present, a change in the colour of
the animal must result. It has, moreover, been
proved that this change can only be brought about
so long as the animal's power of sight remains.
Destruction of the eyes renders the pigment masses
immovable. Section of certain nerves has a like
effect. When any of these animals are pursued by
their enemies, they are thus enabled, by rendering
themselves pale and therefore less easily seen, to
elude their would-be captors. Emotions other than
fear may also, perhaps, be expressed by this means,
and not only can some creatures render themselves
pale, but actually approximate their colour to that of
their surroundings. Such is the permanent state of
very many animals ; this condition being brought
about by natural selection, e.g. lions, sand-colour ;
muddy water fish, mud-colour ; green, sloths, &c. &c.
Pallor, as an expression of human terror, brought
about by a contraction of small blood-vessels, may
have had a similar cause, it at least seems analogous.
— D. A. K.
Holes in the Head of Pike. — The apertures .
on the head of the common pike (Esox lucius) are
the openings of follicles, or mucus-secreting glands.
Similar but smaller openings may be found along the
lateral line that separates the dorsal from the ventral
half of any fish. These openings form an uninterrupted
series, from head to tail, and constitute the opening of
muciparous ducts that may be seen as white threads
by the naked eye on dissection. The function of
these glands is obvious ; they secrete the mucus
by which the integument of the animal is lubri-
cated, and probably act also as sweat-glands to
excrete waste products from the system. — R.
New Habit of Red Grouse. — It does not matter
whether Mr. Dixon or Mr. Dealey claim the honour
of calling the attention of naturalists to the habit of
Red Grouse perching on trees. It is a habit that all
persons who reside near the moors (who take any
notice of the habits of birds) are familiar with. I
saw them perching on trees and hedges years before
the time they say they first observed them. — Jatnes.

BOTANY.
ASPLENIUM SEPTENTRIONALE AT DOLGELLY. —
It has been known for some years amongst a few-
lovers of nature that not only Asplenium septcntrioiiale
but also A. gcrmanicum, Weiss, grew in the Dolgelly
district, and it has only been from a desire to preserve
the plants from extirpation that the habitat has not
been made public. Now that it is known, it may be
well to place the discoverers' names on record.
Asplenium septcntrioualc was discovered in 1867
growing on an old wall not far from the river Maw-
dach, by Mrs. Chamberlain Barlow, of Edgbaston.
The plants of it (two only I think) were of course
spared, and for some months I saw them every
time I passed the locality, peering stealthily at them,
for fear they should be discovered by some ruthless
collector, and believing at that time they were the
only plants in the country. After a considerable
interval, when I revisited the spot, the wall had been
altered or repaired, and the little ferns had dis-
appeared. Some time afterwards the Rev. W. Foley
Vernon, of Shrawley, searched the crags on a hill
that rose up behind the old wall, and had the plea-
sure of finding both A. scptcntrionale and A. ger-
manicum in tolerable abundance, and I have a fine-
grown plant of each which I owe to his kindness.
I enclose a few fronds. May I ask your botanical
contributors if they know of any locality where
one only of these two species is indigenous without
the other occurring somewhere in the immediate
neighbourhood? An acute observer has informed
me that they are always found together, and sus-
pects a more intimate relationship than is generally
supposed to exist between them. — T. Belt.
Gentiana acaulis (L). — Without in the least
wishing to impeach the veracity of Mr. Colebrook,
especially as he is "as certain as he is of his own
existence," that this plant was growing upon Cader
Idris in August, 1862, I would inform him firstly
that, so far as my experience goes, the G. acaulis of
the Swiss Alps is in its full bloom towards the middle
of June, and completely and entirely over by July,
ripening its seed in that month. Its place is then
taken by G. bavarica, and others of that section, as
well as G. campcstris, Germanica, and Amarella,
which are essentially August flowerers. With regard
to the remarks, "the present plant has no stalk,
whence its name acaulis, but cultivated in gardens it
becomes [sic] one," — does Mr. Colebrook here in-
tend to make a playful allusion to its peregrinatory
powers, as well as origin, the word stalk being a
double-entendre in the sense of a stalker. I believe
G. acaulis was found at Stafi'a in the month of June,
1834-5 ; but doubtless it had escaped from cultiva-
tion, as the plant has never been seen there since that
time. Concerning the subject of Mr. Colebrook's
other query — Cotoueastcr — I obtained it in the month
of June, 1874, from the one situation on the Great
Ormeshead, where it is still to be found ; and I must
say that had I not been guided to the spot by one
who knew it well, I might be still searching, but in
vain, for it. Associated with it, in the clefts of the
limestone rock, was abundance of the local Potcntilla
vcrna.—J. C. M.
Gentiana acaulis. — I have been interested in
reading the remarks on this plant that have appeared
lately in the pages of Science-Gossip. Many years
ago I came across what I had no doubt was Gentiana
acaulis, growing in tolerable profusion, and, as might
be supposed, truly wild on the downs between the
Needles and Freshwater, in the Isle of Wight. It
was a small plant, without stalk, about i^ inch
high, half of which comprised the large bright blue
flower. At that time I was not aware that Gentiana
acaulis was "not a native," so I made sure of my
prize, and gathered as much of it as the strong wind
blowing at the time would suffer me to do. On
subsequent examination and reference to Sowerby's
"English Botany "and other authorities, I came to
the conclusion, and I believe rightly, that it was the
veritable Gentiana acaulis. A little further down the
slopes of the hill, upon the same occasion, I came
upon Gentiana Aviarclla, so I had an immediate
opportunity of comparing the two flowers and
observing the wide difference between them. Some
time after this I became aware that the lovely little
Gentiana acaulis had been excluded by botanists from
its former place in the British Flora, and I have often
wondered since how it came to pass that its beautiful
blue flowers had found that accidental lodging far
away from houses and gardens, up on the wind-blown
heights of the Freshwater Downs. I have never
visited the spot since, and I should be glad to know
whether any of the readers of Science-Gossip have,
like myself, ever met with it in their wanderings in
that locality. — Isabella H. Knox.
Plant Chemistry. — Professor Church has ex-
amined the colouring matter of the well-known
bordering plant with variegated leaves, Coleus Ver-
shajjeltii, and thinks that it is identical with a-nobin,
the colouring matter of red wines, as well as with
other substances extracted from blue and purple
flowers.
Solanum Dulcamara. — Can any of your readers
give me any information as to the properties of the
berries of this plant ? " Chambers's Encyclopaedia"
says, "red berries of tempting appearance, which,
being poisonous, are not unfrequently the cause of
serious accidents, particularly to children." Garrod,
in his " Materia Medica," says he has administered
half a pound of the ripe fruit as a conserve, and
without any definite effect. Buffon says " the scarlet
berries are not poisonous, five pounds weight given
in the course of ten days did not produce poisonous

effects " ; but neither of these authors says if the
berries were swallowed by man or beast. I think
I should have a difficulty in finding any one
who would eat even two or three berries, as they
are almost universally considered poisonous. — Dr.
Morton, New. Brompton, Kent.
Hybrid Primula. — The frequent tendency of the
Primrose family to hybridize often causes a difficulty
in determining a plant and its varieties. The Primula
clatior is by some supposed to be a hybrid between
the P. veris and the common primrose ; and Sir
William Hooker " was not satisfied that the Primula
clatior of Jocquin was really distinct from the nu-
merous hybrids between P. vulgaris and P. veris."
In one locality near Geneva I found both growing
together in abundance, producing different forms of
hybrids, some approaching one parent plant and some
the other. Many Swiss botanists call the P. vulgaris
acaulis, as it appears to be stemless, with a variety /3,
which, as having an evident, though very short, stem
or scape, they place the Primulas in two divisions,
as "especes legitimes capsule fertile," and "especes
hybrides capsule avortee " : under the former they
include P. veris, P. vulgaris, and P. elatior ; under
the latter, Primula acatdi-officinalis, P. acanli-clatior,
and P. elatiori-qfficinalis. — T. B. W.
Anomalous Parts of Plants. — I gathered
some Trifotium repens this last summer at Esholt,
near Bradford, the calyx segments of which were
transformed into leaflets ; in some of the heads all
gradations betwixt leaflets and calyx segments could
be observed. I afterwards gathered some in Chee
Dale (Derbyshire), in which all the calyx segments
were converted into leaflets, some of the latter being
on petioles several times the length of themselves.
Two friends of mine have noticed this also, but I
have not seen it recorded. I gathered some speci-
mens of Ctaytonia perfoliata at Bakewell, in all of
which the leaves that are usually perfoliate were not
so at all. The several text-books I have been able to
consult (including Symes) do not give any habitat
for this plant : the specimens I gathered were grow-
ing amidst Chrysosplenium oppositifolium in the
middle of a wood, which appeared a very unlikely
place for its introduction as a weed of cultivation.
I collected also in the same wood a Myosotis, having
the corolla nine-partite. Near Bradford I gathered
Sitene inflata with two complete flowers (except the
calyx) in one calyx ; also in this neighbourhood,
Lotium pe?-enne, in which the spikelets were trans-
formed into spikes. Near Leeds I collected y uncus
bufonius in a viviparous state, like that which J uncus
supinus often assumes ; but I have not seen this state
recorded. I gathered a specimen of Lychnis diurna
near Miller's Dale, in which the stamens were trans-
formed into petals. At Eldwick, near Bradford, I
got a specimen of Orchis maaelata, which agreed
with the description of that plant in every particular
save the lip, which was about twice as long as usual
and strap-shaped, with parallel sides, tridentate, the
central lobe being less than the others. I have re-
ceived from Scotland a specimen of the common
Dandelion, the peduncle of which is furcated, bear-
ing two capitula. — Win. West, Bradford.
Inflorescence of Gourds and Pumpkins. —
In Science-Gossip for November was an interesting
note on the above topic by John Gibbs. He notices
that the fruit on fertile blossoms appear first — before
the sterile blossoms on the same plant. In this
country (Michigan, U.S.A.) I have often noticed
many staminate or sterile flowers open before a single
pistillate flower had opened. This I have repeatedly
seen in case of Hubbard squashes, summer squashes >
and several varieties of cucumbers. I do not make
this assertion as doubting what Mr. Gibbs has said,
but as a curious difference. If he is correct, perhaps
our warmer and drier summers may have something
to do with it.— W. J. Bcal.
Gourds and Pumpkins. — The fact to which Mr.
Gibbs calls attention is one of considerable interest.
The separation of the sexes is common enough in
flowering plants, and in the Gourd tribe is of two
degrees : on distinct flowers (moncecism), or on dis-
tinct plants (dicecism). It has also been noticed in
these delicious flowers, as well as in those structurally
"hermaphrodite" or "monoclinous," that the sexes
are sometimes developed simultaneously (synacmic),
sometimes successively (dichogamous); but of the two
possible cases of the latter — at least in "monoclinous"
flowers — the precedence of the male (protandry) is
far more frequent than examples similar to the one
Mr. Gibbs describes (protogyny). This might be ex-
pected in single flowers, since the stamens occupy an
older whorl than the carpels ; at least, are generally
believed so to do. But when we come to diclinous
plants, new interests arise. A most careful and as-
siduous American observer, Mr. Thomas Meehan, of
Philadelphia, has shown that there is a close relation
between sex and energy, and that female flowers are
more characteristic of strong shoots than male.
Might we not, therefore, expect a plant to produce
male flowers only after its energy has been to a cer-
tain extent exhausted in producing female ones ?
Numerous cases are on record, especially of figs and
oranges, of the swelling of the "fruit" without the
fertilization of the ovule : it would be interesting to
learn if this ever is so with gourds. Of course, how-
ever the "fruit-blossoms" may "make haste," they
cannot set seed without pollination. In this case,
the pollen must be derived from another plant pro-
bably, perhaps from another situation where different
conditions make gourds flower earlier ; so we may
have here an illustration of Mr. Darwin's rules that,
while pollen from another flower of the same plant is
little, if at all, better than that of the same flower,
pollen from another plant is an advantage, and if

from one grown under different conditions, even still
more so. I hope Mr. Gibbs will continue his obser-
vations. He could not have a more interesting or
practical subject. — G. S. Boulger.
Fertilization of Flowers. — Dr. M idler has
called attention to the occurrence, in some of the
Labiates, of two distinct forms, one with larger
hermaphrodite protandrous flowers, and the other
with smaller female flowers. He shows that the
latter can only be fertilized by the former, and that
they disappear when the former are not present.
We would suggest that otr botanical readers should
devote their attention during the coming summer
to the analytical structures of well-known and
abundantly-represented orders of plants ; and, further,
that they should also note the kind of insects which
frequent them, and whether these insects affect any
-special colours of flowers.
GEOLOGY,
Prehistoric Man in Japan. — Mr. E. S. Morse
sends a note to Nature, in which he gives an account
of the Kitchen Middensat Omori, in Japan, which con-
tained arrow-heads, bone implements, but no flint or
■stone weapons. Mr. Morse believes these large
shell mounds were accumulated by a prehistoric race
of men in Japan.
The Insect Fauna of the Paleozoic Period.
—Mr. Herbert Goss, F.L.S., has read a paper on
the above subject before the Brighton and Sussex
Natural History Society. This makes the third
•of Mr. Goss's papers on fossil insects, and it is equal
in character to its predecessors. In these three
papers the geological student is possessed of a most
valuable generalization of all that is known on fossil
entomology.
Jointed Limbs in Trilobites. — Mr. C. D.
Walcott has just figured and described jointed limbs
in the genera Calymenc and Ceraurus, from the Tren-
ton limestone. Calymene senaria showed axial ap-
pendages with three joints. In Ceraurus pleurex-
anthemus the limb was five-jointed. The legs ended
in a single blunt end, and Mr. Walcott thinks these
•trilobites will be found to have five or six joints with
a terminal claw. He further thinks that the dis-
covery of these limbs more closely than ever as-
sociates the Trilobites with the King-crabs and
Eurypterids.
The Cumberland Association of Litera-
ture and Science. — A copy of the Transactions of
•this vigorous natural history and literary society has
been sent us, and it is a pleasure to find so high a
degree of culture so far removed from the centres
where culture is supposed to be especially confined.
But the development of local science is nearly always
•dependent upon the personal interest taken in it by a
few men, and there can be little doubt that the
great success of the Cumberland Association during
the last two or three years is mainly due to their
possessing such an indefatigable secretary as Mr. J.
Clifton Ward, F.G.S., of her Majesty's Geological
Survey, the author of a number of remarkably sug-
gestive papers on Geology and Physical Geography.
Artificial Precious Stones. — MM. Fremy
and Freil have recently been experimenting on artificial
productions of corundum, ruby, and other crystal-
lized silicates. They showed that in a crucible of
refractory earth they put a mixture of equal weights
of alumina and minium and calcined them for some
time at a red heat. After cooling, they found two
layers, one vitreous (formed chiefly of silicate of
lead) and the other crystalline, and often presenting
geodes full of beautiful crystals of alumina. To obtain
the red colour of ruby, about two or three per cent,
of bichromate of potash was added to the mixture of
aluminia and minium. A silicate of aluminia was
produced by heating for some time a mixture of equal
weights of silicon and fluoride of aluminia.
Precambrian (Dimetian and Pebidian) Rocks
in Caernarvonshire. — At a recent meeting of the
Geological Society, a paper on this subject was read
by Dr. Hicks, F.G.S. The author gave an account
of the special examination of the great ribs of so-called
intrusive felspathic and quartz porphyries which are
found associated with the Cambrian rocks in Caernar-
vonshire, made by him in company with Professor
Hughes, Mr. Hudleston, and Mr. Homfray last
summer. He described sections at and near Moel
Tryfan and across the mass from Pen-y-groes to
Talysarn, in which he showed that instead of being
of an intrusive nature, as hitherto supposed, the
whole, with the exception of a few dykes at those
parts, is made up of bedded volcanic rocks, lavas,
breccias, &c, similar to those found in the Pedibian
series at St. David's, and that the Cambrian rocks,
instead of being intruded by this mass, rest every-
where upon it unconformably, and the pebbles in
the conglomerate of the Cambrian at the base are,
as at St. David's, identical with, and must have been
derived from, the rocks below. Similar results were
obtained in the examination to the north and south of
Llyn Padarn, and the conclusion, therefore, at which
the author has arrived with regard to the great mass
which extends from Llanellyfine in the south to
St. Ann's chapel in the north, is that it is entirely
Precambrian, and that it belongs to the series de-
scribed by him under the name Pebidian at St.
David's. The other mass, extending from Caer-
narvon to Bangor, he considered also entirely
Precambrian ; and from the mineral characters ex-
hibited by a portion of this mass directly behind
Caernarvon, he thought it would prove to be, at
least at this part, of Dimetian age. The altered beds
near Bangor and their associated quartz felsites he

considered entirely of Tebidian age, as there is no
evidence that the Dimetian rocks are exposed there.
Afterwards, Professor Hughes read a paper on the
Precambrian rocks of Bangor, which consist of slates,
agglomerates, and porphyritic rocks ; and these, he
thinks, are equivalent to Dr. Hicks's " Pebidian."
Palmam qui meruit. — The Royal Society of
England have just awarded Professor James D.
Dana, the distinguished American mineralogist and
geologist, their highest honour, the " Copley Medal."
The "Royal Medal" went to Professor Heer, the
equally distinguished fossil botanist, of Zurich.
A Fossil Fungus. — A very interesting article in
your last number, which is headed " A Fossil
Fungus," refers to the discovery of a fossil fungus
in Lepidodendron, by Mr. Carruthers, and its subse-
quent study and classification by Mr. Worthington
Smith. It is there stated: "This is, perhaps, the
oldest fungus on record. " As this is not quite correct,
I beg to inform you that in 1858, C. Wedl found
something very much like Saprolegnia ferox in a
Leptiena from the Devonian. In May, 1876, I read
a paper before the Geological Society, in which
unicellular algoe were described parasitic within a
foraminifer from the Lower Silurian, a coral from
the Upper Silurian, in brachiopods, and corals from
the Devonian, and from a coral in the Miocene.
I named and figured this penetrator Palceachlya
pcrforans. In the Proceedings of the Royal Society,
No. 174, 1876; I explained the physiology and
morphology of AcJilya penetrans, now found in
recent corals and shells, and explained the life
cycle of this saprolegnions plant, so that, from its
almost complete resemblance with the ancient form,
it could be considered its descendant. The septa,
which are said not to occur in the mycelium of
Saprolognia are really seen very rarely, but still they
do exist. — P. Martin Duncan.
Erratum. — In my last paper on the Carboniferous
Polyzoa, December 1S77, the reader will oblige by
correcting the following : page 272, 8th line in list,
G. flesicajinala read G. flexiearinata. Page 273,

NOTES AND QUERIES,
The Pairing of Birds. — Is it sufficient proof of
birds pairing for life, that we find the old nests
tenanted year by year ? Some birds are known to
use the old nests of other species ; e.g. , the House
Sparrow, which is one of the species which, upon this
evidence, Mr. Dixon quotes as pairing for life,
frequently uses the old nests of the House Martin ;
and if of other species, why not of the same species ?
I fail to see why Mr. Dixon supposes that polygamy
tends to prolificness : it can only do so if the number
of females born, or arriving at maturity, be in excess
of the males. Among mankind, as men and women
arrive at adult age in about equal numbers, if one
man have two wives, another must go without one,
and it is obvious that both the procreative power, and
what is probably of more importance, the power to
maintain offspring of two males, will be greater than
that of one male. Polygamy can only tend to a
more rapid increase of population where the number
of females is much in excess of that of males, either
through female immigration, as in the Mormon settle-
ments, or, as more usually happens, through the
greater mortality of males. It is hard to believe that
nature has been so considerate to mankind as to make
fowls polygamous in order that the superfluous males
may afford us food. It seems more reasonable to
suppose that the habit of polygamy is in some way
advantageous to the polygamous species itself.
Polygamous animals are usually provided with special
weapons of offence, like the cock's spur, and are in
the habit of fighting for the females : the strongest
and best-armed male wins the largest number of fair
prizes, and the progeny of such a male are likely to
have the advantage over their competitors in the
struggle for existence. It does not seem difficult to
explain why species which are monogamous in the
wild state should be polygamous in captivity. Given
an excess of females over males, and in the absence
of social and moral restraints, polygamy follows as a
matter of course. — H. F. Parsons, M.D.
Pairing Instincts of Birds. — If birds returning
to their old nests is a sign that they pair for life,
I may add to Mr. Dixon's list the Blackbird ( Tnniits
mcrula), for a nest has been occupied successively for
the last three years by a pair of these birds. Now as
there are two or three other nests in the same hedge,
I think it must be the same pair that has successfully
reared three broods in the one nest. Perhaps
Mr. Dixon— since he has been observing particularly
the pairing instincts of birds — could kindly give me
some information as to one species of bird pairing with
anather (see Science-Gossip, p. 263). I have known
instances of hybrid grouse, but never of a hybrid
between a blackbird and a thrush. — G. F. B.
Mites in a Collection of Lepidoptera. — In
reply to the query in the December number of
Science-Gossip I beg to say that, having had the
misfortune to find mites in my collection of Lepido-
ptera, I was recommended to try naphthaline, and so
far as I am at present able to perceive, no further de-
struction has taken place since I used the same. I put
the naphthaline in a small pill-box with a perforated
lid, which is glued into the corner of the drawer, and
does not attract attention. Any insect specially
affected should be removed from the cabinet or store-
box and carefully painted on the thorax with corro-
sive sublimate. — A. J. R.
Destroying Mites on Lepidoptera. — In
answer to "A. F.'s " query on this point, let me draw
his attention to the following extract from Mr.
Newman's preface to his splendid work on British
Butterflies and Moths : — " Directly you observe any
dust, however little, underneath an insect, ....
take out the infected individual ; as soon as he is
removed from the drawer, drop benzole on his back,
drop after drop, until he is thoroughly saturated, and
all his wings are rendered perfectly transparent. In
this state remove him to the drying-cage, and there
let him remain until all the benzole has evaporated,
and his colours have returned, bright and beautiful as
ever." I have not tried this method myself, but I
have friends who have, and they find it to answer
perfectly. — W. J. B.

HARD WICKE 'S SCIENCE - GOSSIP.
The "Furniture" Beetle. — Having just been
put to much expense by repairs to furniture and
skirting-boards, &c, which have been injured more
or less by the furniture beetle, I should be glad to
elicit any remarks upon its probable cure or pre-
vention. I have generally found it in the sappy part
of the wcod, and have found it in every kind of wood
used in house-building and furniture, except in ma-
hogany ; and I cannot hear of its being ever found in
pitch pine. I am not sure of the correctness of my
supposition, but I think that the beetle (it is not larger
than a middle-sized pin's head) bores and lays its egg
or eggs, and the grub eats till its changing period,
the beetle from which then eats its way out ; the
holes not being larger in bore than a middle-sized pin.
I have just been taking out several pieces of wood in
my house, but could not detect the insect itself in any
stage of existence. I have only twice seen the beetle,
and can recollect the time was summer or autumn.
On my own premises I have also found it out of
doors, in old wood laid aside two or three years for
burning. I hope to have some remedy discovered
that may protect the new wood now replacing my
damaged furniture and shelves. — y. Hashes.
Mistletoe. — In reading the short notes on this
species in the December Science-Gossip, I remem-
bered seeing many large specimens some few years
ago when engaged as a botanical collector in Nor-
mandy, that would with ease have been sufficiently
long in the stem to have made a "small javelin."
At the time, I took particular notice, but I do not
believe I saw a single example on the Oak ; the
finest specimens were observed on the Lombardy
Poplar. It is very abundant in the north of France.
— R.
Mistletoe on Lime-trees. — I do not think that
this is an unusual phenomenon. Next to the Apple,
the Hawthorn, and the Black Poplar, I should say
that the Lime was the most frequent host of the
Mistletoe. I have never seen the mistletoe growing
in greater luxuriance than on two fine avenues of limes
at Cutteridge House, near Westbury, Wilts. Near
Malvern, where the mistletoe is abundant, I have
seen it growing on a variety of other trees, as the Oak,
the Maple, the Willow, and Robinia Pseudacacia. —
H. F. Parsons.
Seeds of Mistletoe. — Some twenty-two years
ago I put two seeds of Mistletoe in a cavity formed
on the stem of a young apple-tree, caused by the
partial healing over of the part where a small branch
had been cut off the previous season, tying a string of
bass over to prevent birds, &c. from picking out and
devouring them. They both took, and in three
years had grown to about three inches in length ;
since then they have grown to about two and half
feet through, but during the time have only produced
three berries : that was two years ago. Since then
one of the plants has died. It first showed symptoms of
decay by the leaves becoming yellow and dropping
off; since then it has fallen away piecemeal by
breakage at the joints, the larger portions still remain-
ing attached. The other plant, although so close,
remains in perfect health and looks as usual, except
that it is much thinner from the loss of the inter-
mixed branches of the former plant. I cannot say
which of the plants is dead, — either that which bore
the berries or otherwise, but the remaining plant has
no berries this season. Until the berries were pro-
duced, I had a notion that the plants were of one sex,
consequently barren, but had always neglected ex-
amining them to ascertain the fact, which I now re-
gret, as I fancy the berries produced were barren ; — at
least, none of them grew when inserted in the usual
way. My plants, at first, were of very slow growth :
the first season only produced two small stumpy
leaves from each seed ; the second, four on each, and
so on ; and I rather think only one joint in length has
been produced of a season, but as the plant got
stronger, frequently four shoots were produced instead
of two, increasing thereby much faster, as well as
forming a handsomer and much stronger-looking
plant. Some years ago, I was much pleased and
interested by observing, about an inch above the
plant, several young plants which had pushed their
way through the bark, which they have since con-
tinued to do, always ascending, and about an inch
from each other, some of which are now dead and
some living ; from which I draw the conclusion that
those produced from the former plant are dead also.
These off-sets were of equally slow growth as the
young seedlings, only a pair of leaves of a season,
although more elongate, and I cannot understand H.
E. Wilkinson's statement when he says he observed a
protuberance and very soon a leaf, — mine always
came in twos — and presently a good-sized plant of
Mistletoe. Mine always take four or five years to
come to anything like a good-sized plant, and I have
grown many since the first, both on apple and pear-
trees. The " Dumelow Seedling" is the apple on
which my large plant is now. It was removed once
when the Mistletoe was about five years old : it made
not the slightest difference to its growth ; but I have
lost plants by removing the tree when only of the first
year's growth. I also lost a fine young plant of four
years' growth by the dying off of the tree itself by can-
ker of the root, the Mistletoe living some months after
the tree died, but losing colour and becoming rigid,
and finally perishing also. My trees do not suffer in
the least from the growth of the parasite on it, either
in growth or bearing, although established on the
main stem about three feet from the ground. — Wm.
Curnow.
How to Preserve Animalcul.e. — I have several
works on the microscope, but I have never read of
any way to preserve animalculce ; that is, the best
medium to use. I have tried several, but none have
acted satisfactorily; viz., spirits, glycerine, glycerine
and camphor : the last was the best. I mounted
some Canthocamptus minatus and some ChyJorns
sp/uzricus in it, and found the objects looked better
than when preserved in the other mediums, but still
they were not to my satisfaction. Could you, or
some of your correspondents, tell me of some better
medium, I should be greatly obliged. — II, Foley-
streei, Portland-place.
Root- Propagation of the Ipecacuanha. —
In a paper on i-oot-propagation read by Mr. Lindsay,
of the Edinburgh Botanic Garden, before the Scottish
Horticultural Association, that gentleman stated a
curious fact in connection with the propagation of the
Ipecacuanha by that operation — viz., from a piece of
the root about a foot long or only one of the rings of
the annulated root, one plant would be the conse-
quence. Have any of the readers of Science-Gossip
had any experience of the multiplication of that
highly serviceable plant in that way ? — M. King.
Badly-blown Eggs. — If any of the able corre-
spondents to your journal could tell me of some fluid
that would dissolve the hard albumen in badly-blown
eggs without affecting the shell, I should be much
obliged. I have had some rare eggs given to me
that I wish to preserve, many of which are so badly
blown that they have broken with very careful
handling. — G. T. B.

Preserving Animals. — I have just seen an
article mentioning a method of preparing insects,
fish, &c, for the cabinet, said to have been practised
many years by Mr. Waterton, of Walton Hall. It is
stated that the specimens are perfectly life-like, and
not liable to damage by moth, mite, mould, or grease.
I should be much obliged to any reader of SciENCE-
Gossip who would give me a few details of the pro-
cess, or refer me to some work containing the neces-
sary information. — IV. G.
Stormy Petrel. — Dr. Keegan, in his article in
the September number of Scence-Gossip, states
that this bird is only found in the wake of vessels
during stormy weather. He then goes on to give a
very ingenious theory to account for this, or rather to
account for their following ships at all. In the North
and South Atlantic, where the trade winds prevail
and storms seldom or never occur, Mother Cary's
chickens are constantly seen, and frequently near the
equator, where possibly there is not a ripple on the
water at the time. I think it is hardly necessary,
when accounting for these or other birds following
vessels, to bring forward a theory of their supposed
love of the beautiful. The fact is, they know by ex-
perience that substances— to them very great delica-
cies— are continually thrown overboard, and they will
as readily follow a hideous collier as a magnificent
full-rigged ship. On the Thames, the Herring Gulls
have the good sense to prefer fishing-boats, however
old and dirt)', to the smartest yacht on the river, well
aware that from the former they will obtain the larger
amount of food. — y. S. G.
The Veteran Eel. — I think that this subject will
be one of interest, not only to " E. L.," but also to
many aquarium-keepers, particularly so when we read
of the death of an eel at the age of twenty-two years.
I for one should be glad to know from Mr. Plant its
size when he first had it, and at its death. Two years
ago I had an eel which has grown three quarters of
an inch in my keeping, and is now nearly four inches
long. If this be the proportional rate of growth, we
shall easily see to what length it will have attained in
twenty-two years. I find that the best material to
feed eels upon is the common blood-worm, which
ought to be well washed before being put into the
aquarium ; otherwise some of the mud in which they
live will be thrown into the tank. — J. J. Newton.
Cement for Marine Aquaria. — I can fully
endorse the opinion of Mr. Worster as to the value
of pitch as an aquarium cement, especially when used
in the manner which I shall presently describe. A
year and a half ago I rendered perfectly water-tight
an eight-gallon tank which had been for years thrown
aside as useless, and it has not leaked a drop since.
This last spring I built another, holding about eighteen
gallons, with an inch slate bottom, to which are
screwed through holes drilled in the slate, the two
ends of Spanish mahogany, well clamped to prevent
warping, and lined with stout roofing slates cut to
exact size. Into the mahogany ends the front and
back of plate glass are grooved, and the whole
finished with a strong mahogany capping rail all
round, which also serves the purpose of tying die
two ends well together. The glass is of course set in
red-lead putty, and after giving the latter time to
harden, I coated all the joints, the inner faces of two
wooden rails into which the bottom of the plate glass
was set, and in fact, every part which was likely to
leak, with a mixture of pitch and gutta-percha
(about quarter part of the latter). This mixture was
laid on pretty thick with a putty-knife when just hot
enough to stick. I then cut strips of sheet glass of
suitable widths, and from two to four inches long,
heated them over a small gas stove, and pressed them
while hot into the pitch : of course, a pair of hot pliers
must be used to handle the glass with, or it will fly.
This plan I have found to answer admirably ; it
prevents the pitch from chipping or flaking off, and
the best of it is, a tank so treated is ready for use im-
mediately, as there is no effluvia of red-lead to be
got rid of, eveiy particle of poisonous cement being
covered up with pitch and glass. This tank has now
been stocked about four months, and is in eveiy
respect satisfactory. I may mention that one or two
of my friends and myself have long been in the habit
of using for rock- work a calcareous tufa found in this
neighbourhood. It can be obtained in good-sized
pieces, forms a good nidus for conferva, and is easily
worked out into caves and hollows suitable for
aquarium animals to shelter in, whilst at same" time
hard enough for the purpose. It also has the advan-
tage from its porous nature, of holding a good deal
of water, so that the space it occupies is not all lost.

Aquariums. — Why should sticklebacks fight so
in aquariums, as "S" says, unless they cannot get
food properly ; for they live in shoals : at least, we
find numbers together, though at times they seem
very jealous of one another, and do not like intruders
into their peculiar domain ? — Edward Thomas Scott.
Slugs and Foxgloves. — With reference to
Mr. J. W. Slater's observations respecting slugs and
snails feasting heartily on the leaves of the Foxglove,
I can testify to my fowls doing the same thing with
impunity — without any bad result to those who sub-
sequently eat their eggs. — G. F. Cooke.
Unusual Appearance of the Martin. — This
week (December 4) this bird is busily flying about
the summit of Overton Hill, Cheshire : it selects a
sheltered wooden shed every evening for its roosting-
place. It must have been a late-hatched bird, and
thus left behind when its friends migrated. My
little boy, who takes a deep interest in ornithology,
states he believes it has been injured, and, therefore,
not able to undertake the wearisome journey to a
warmer climate. Mr. G. White would probably
have made much of this fact in his day. — R.
White Hairbells. — On October 31st, I gathered
several beautiful albino specimens of the common
hairbell ( Campanula rotundifolid), by the side of the
Upper Shaftesbury road, about a mile and a half
from this town. I gathered several on the same spot
in October last year. It is noticeable that although
not the slightest trace of colour was discernible in the
flowers, yet, upon being dried, they assumed a bluish
tinge. The ordinary pigment was therefore not quite
absent, but was only precipitated in the process of
pressing. Is not //a/rbell, as above, the correct name
for this graceful little flower, on account of its fine
hair-like stem, and not harebell, which is quite un-
meaning ? — W. R. Tate, Blandford.
Bournemouth Insects. — With reference to
Mr. Groser's remarks (p. 256, November number)
upon the larvae of E.jacobea, I may mention that I
have seen them here regularly year after year on the
Ragwort, but have often observed that they occur in
patches ; i.e. one patch of ragwort will swarm with
them, while the next will have none. I infer that this.
is due to the sluggish flight of the insect. Bourne-
mouth possesses an excellent list of local lepidoptera ::
I may instance, N. viridata, E. cribrnm, H.
dipsaceas, B. trifolii, L. littoralis, and others. —

HARDWICKE'S SCIENCE-GOSSIP.
NOTICES TO CORRESPONDENTS,
To Correspondents and Exchangers. — As we now
publish Science-Gossip at least a week earlier than hereto-
fore, we cannot possibly insert in the following number any
communications which reach us later than the 9th of the
previous month.
Science Gossip Botanical Exchange Club. — In our
last number we prematurely stated that all the parcels had been
made up and sent out in connection with the above club. The
majority of them have been delivered, but there still remain
others, which will be forwarded as soon as possible. The work
of arrangement and exchange has been enormous, and we must
beg those members who have not yet received parcels to enter-
tain a little patience. We feel certain that the result will
satisfy all parties.
J. Bramhall. — It is not at all meditated to bring out a
second edition of Blackwall's " Spiders " at present. We are
not aware whether Messrs. Douglas & Scott have yet pub-
lished their monograph on British Homoptera.
S. T.— Get the "Collector's Handy Book," price 2s. 6d.,
published by Hardwicke & Bogue, 192, Piccadilly. You will
there find full instructions as to mounting microscopic objects.
The best way of preserving animal bones is to steep them in
gelatine, or boil them in a solution of glue.
F. H. L. —The "coral-like substance" you sent us from
Falmouth beach is not a coral but a lime-secreting sea-weed,
called by Harvey Melobesia fasciculata. It is allied to the
common Corallina officinalis.
E. Edwards. — Many thanks for your good wishes. You
had best procure Robson's book of " Botanical Labels" from
Messrs. Hardwicke & Bogue, and paste each label on the
species.
W. K. (Leeds). — We know of no better way of hermetically
sealing specimens in bottles containing spirits than the old-
fashioned one of covering the outside of the cork with a layer
of melted sealing-wax.
K. A. Deakin. — The Palaeontographical Society have
published the fossils of nearly every British formation, and
these are contained in about thirty large volumes. By applying
to the secretary, Rev. T. Wiltshire, Lewisham, we have no
doubt you could obtain a list of all the society's publications.
You can get the implements you speak of at any large natural-
history dealer's.
J. H. Morton. — There is no possible danger of being
bitten by the slowworm (A nguis fragilis).
S. T. — For stocking small aquaria see instructions con-
tained in "The Aquarium, its Structure and Management,"
published by Hardwicke & Bogue, 192, Piccadilly.

THE PRONUNCIATION OF SCIENTIFIC NAMES,

T is a source of satisfac-
tion, I should imagine,
to all authors, when
they find that their
works are read ; and
I feel flattered that Mr.
Newlyn should quote
from my work, "Bo-
tanical Names for Eng-
lish Readers, " especially
as, in the half-dozen
pages I wrote on the pronunciation of scientific
names, I aimed only at giving a few plain, though to
the best of my knowledge correct, hints on the
subject to those who might wish for them ; but by
no means at assuming the position of a teacher of
this matter to those who, by their knowledge of
Greek and Latin, are competent to form a judgment
of their own. But Mr. Newlyn, in his article on the
pronunciation of scientific names (No. 153, p. 193), has
misunderstood my meaning. He says : " Mr.
Randal Alcock points out, in a rule, that in words
direct from the Greek, especially modern scientific
terms, the g is pronounced hard " ; and remarks,
" Really, this is implying that the older terms may
go their own way as regards our dealing with this
letter in any of them, and the young student in
botany must be utterly puzzled in his attempts at
utterance of scientific language." Perhaps these
words of mine, thus separated from their context,
may seem to imply what is stated, but not other-
wise. The sentence immediately preceding the one
quoted is : " Those Greek words that come to us
through the Latin, and have been long in use with
us, generally follow English usage, and are pro-
nounced soft, though not always ; for instance, both
gymnastic and jymnastic may be heard." In an
earlier part of the same chapter, I endeavoured to
show how much pronunciation must depend upon
usage, and how futile it is to lay down hard-and-fast
rules to meet every case. I have, therefore, not left
it to be inferred that any class of terms " may go
No. 15S.
their own way," but I have said the rules must be
modified by usage.
Mr. Newlyn disagrees with my view that the g in
scientific names from the Greek should be pronounced
uniformly hard, as in Geum and Potamogeton ; in-
deed, he asserts that it should not be in these cases,
though he allows that authorities differ. I entirely
agree with Mr. Boulger (No. 152, p. 191), when he says
that " a scientific name is a Latin and not an English
word, and must be pronounced, if not spelt, accord-
ingly." This being so, the only question is how to
pronounce Latin, a question which cannot at present
be answered decidedly, as both the traditional English
pronunciation and the new pronunciation are being
taught. Which will ultimately prevail remains to be
seen ; but if the new pronunciation become universal,
there will no longer be any difficulty, or ambiguity,
regarding such names as have been written about in
your journal. Mr. T. D. Hall, M.A., in "A Child's
First Latin Book," which aims at leading "step by
step to the acquirement of the pronunciation of Latin,
as set forth by the professors of Latin at Cambridge
and Oxford," says, "c has always the sound of k :
as Cicero, pronounced Kikero ; Cresar, Kaysar ;
clvis, keevis ; scilicet, skeeliket ; scio, skio. g is
always sounded hard, as in go, gun: as genus, gigno,
regina." We do not meet here with the pronun-
ciation of ch, but in Dr. Smith's "Principia Latina,
Part I.," we find, ' ' Latin c, ch = English &." This
would give us, or the "utterly puzzled" young
student, without any doubt, Rikardsonia as the pro-
nunciation of Richardsonia ; Rikardia of Richardia,
Lakenalia of Lachenalia ; Fuksia of Fuchsia ; Gera-
nium, Totamogeton, Geum, with g like g in gun.
I am very much in favour of the new pronunciation
myself for many reasons, which it is not necessary to
enter upon. I merely say that it has been arrived at
by competent authorities, and is now very extensively
taught. " The usage of our universities " is rather a
vague expression, as they do not all agree ; and so long
as we have English teachers who have studied
abroad, and distinguished foreign savans visiting us
c
26
HARD WICKE'S SCIENCE-GOSSIP.
here, there must always be a certain amount of lati-
tude allowed, if we retain the English method of
pronouncing Latin. We may say Fewschia or ,
Jeranium to an Englishman, but who would do so to '
a German ?
I cannot see, then, that the pronunciation of many
of the names can at present be reduced to strict rules,
which any one would feel bound by ; scirpus is pro-
nounced sirpus, according to the old style ; skirpus
according to the new, &c. ; but in the case of
quantities, I think absolute uniformity might be
arrived at, which is not the case at present. If I were
to ask, what are the correct accentuations of Conium,
Cyperus, Populus, for instance, I should not expect
to receive uniform replies.
As to the euphony of the names, those who have
to apply them are responsible, and they are supposed
to have sufficient knowledge of plants, and the
system of nomenclature, to give correct names : much
of what remains depends upon taste. " It is certain
no one ought to name a plant, if he is not a botanist ;
nor is any one at liberty to impose a generic name
who does not understand genera ; on the other hand,
we have no doubt that any one who knows that a
plant is perfectly distinct generically from all others,
also knows how to apply a distinct name " (Linn.
"Crit. Bot.," § 218). It is true that names are not
always everything that might be desired, nor have
they always been correct ; but if correct, they should
not afterwards be altered. Euphony does not en-
tirely depend upon the taste of the plant-namer, for
often he has little choice. Thus, as Jacquin wished
to do honour to Patrick Browne, and named Brownea
after him ; Smith, when he wished to honour Robert
Brown in the same way, had to invent a fresh form,
and therefore named his genus Brunonia ; Linne
having already used Brunia in honour of Lebrun.
Mr. Newlyn is scarcely correct in saying that
Brownea and Brunonia are "etymologically identi-
cal," for, not only are they derived from the names of
different people, but also, in the first case, the name
was spelt Browne and in the second Brown. Hence
Brownea — Theis has it Brownaea — notBrowma, which
it would have been but for the final e. It is well
these minutice should be noticed, else "both the
complimentary importance and the etymological form
might be sacrificed."
I have not hitherto felt inclined to take any part in
this controversy, because, if common usage be taken
into account, no decisive answers can be given to the
questions asked. Thus "E. C." (No. 151, p. i64)argues
that the ch in Lachenalia should have the sound sh,
because it was "named after M. de la Chenal."
De Theis says it was named after Werner Lachenal,
professor of botany at Bale. Whether he was a pure
Frenchman, or a pure German, or a German of
French extraction, I do not know ; but if he were the
latter, as his Christian name, and changed surname,
would seem to indicate, there is still no certainty how
he pronounced his own name, for the Germans them-
selves do not pronounce ch in a uniform manner ;
some would pronounce it k, some ch, as in the Scotch
loch, some sh ; and there are also intermediate sounds
between these to be met with. According then to
"E. C.'s" idea, he may call Lachenalia what he chooses
without being incorrect ; but certainly Mr. Boulger's
view that it should be pronounced as though it were
spelt with a h, because it is a Latin word, seems
more reasonable. We cannot follow the pronuncia-
tion of all languages in commemorative names, but
must take them as Latin, and pronounce them
accordingly. Magnol pronounced in French, does
not correspond with Mag-no-lia pronounced in Latin.
I repeat, in conclusion, my opinion that when we
have a uniform pronunciation of Latin, we may have
a uniform pronunciation of botanical names, but not
until then. In the mean time, as Mr. Newlyn says,
"the pronunciation of botanical names is but of
secondary importance," and I have taken my pen up
now, only because Mr. Newlyn has misunderstood
what I have previously published on this subject,
and, unintentionally no doubt, misrepresented my
meaning. This is the general teaching of my book,
with regard to the pronunciation of the letter g, in
botanical names. In names direct from the Greek,
it should be pronounced hard; e.g., Geophlia,
Georchis, Geropogon. But if the student always
hears the g, in such words as Genista, Gentiana,
Geranium, in the British Flora pronounced soft, let
him pronounce it soft, though Geranium is a Greek
name of Dioscorides ; or, if he sees, judging by
analogy, that according to English usage, such names
as Gerardia, Geoffroya, Gilia, would be pronounced
soft ; let him follow that usage. I would add, that
if he should be in doubt about such names as
Gireondia, Gesnera, Genipa, Giukgo, let him pro-
nounce the g hard. I hope it may be pronounced so
before long in every case.
THE SEALS AND WHALES OF THE
BRITISH SEAS.
By Thomas Southwell, F.Z.S., &c.
The Sterm Whale {continued).
No. VII.
THE pursuit of the Sperm Whale is attended with
much greater clanger than that of the Greenland
Whale, and Beale gives many instances in which, in
his own experience, boats were stove in and men lost ;
stories of fighting whales, he says, are numerous, and
probably much exaggerated ; one, known as " Timor
Jack," is said to have destroyed every boat sent
against him, till at last he was killed by being
attacked from several directions at the same time,
thus diverting his attention from the boat which made
the successful attack. Another fish, known as " New
Zealand Tom," destroyed nine boats successively
HARDWICKE'S SCIENCE-GOSSIP.
before breakfast, and when eventually captured, after
destroying many other boats, many harpoons from
the various ships which had attacked him were found
sticking in his body. There is one well-authenticated
instance of a vessel being attacked and destroyed by
a sperm whale : the American whale-ship Essex was
attacked by one, which, first passing under the vessel,
probably by accident, came in contact with her keel
and carried it away ; then turning and rushing
furiously upon the ship, the whale stove in her bow ;
so serious was the breach that the vessel speedily
filled and went down. Most of the crew were away
in their boats at the time, but those on board had
just time to launch their one remaining boat before the
vessel sank. The boats made for the coast of Peru,
the nearest land, many hundreds of miles distant ; one
of them was picked up drifting at sea, and three of
the crew, who were found in it in a state of insensi-
bility, were the only survivors of the ill-fated vessel.
In addition to the sperm and oil, this species yields
another product which is, or was, very valuable,
although it is the result of disease, and one would
imagine a very uninviting substance — I refer to
Ambergris, the origin and composition of which was
so long a puzzle to the learned. This substance is
now well known to be a concretion of the indigesti-
ble portions of the Cuttle-fish, which form the food
of the Sperm Whale. The nucleus of the mass is
generally the horny beaks of these creatures, and
the substance itself is found in the intestines of the
Sperm Whale, or on the shores of the seas frequented
by this species : no other whale is known to be
subject to these bezoars. It was formerly believed
that the origin of ambergris was in some way con-
nected with the sea, and when it was afterwards
found in whales, the fact was simply attributed to
their having swallowed it. Sir Thomas Browne
writes of the Sperm Whale which came on shore at
Wells, in 1646 : — " In vain was it to rake for
ambergriese in the paunch of this leviathan, as
Greenland discoverers and attests of experience
dictate that they sometimes swallow great lumps
thereof in the sea ; insufferable foetor denying that
inquiry ; and yet if, as Paracelsus encourageth,
ordure makes the best musk, and from the most
foetid substances may be drawn the most odoriferous
essences ; all that had not Vespasian's nose (Cuiodor
lucri ex re qualibet) might boldly swear here was a
subject fit for such extractions" (p. 356, vol. i.).
It was not until 1783, in a paper read before
the Royal Society by Dr. Swediaur, that a scienti-
fic account of 'the origin of ambergris was made
known. At the present time its medical virtues,
which were formerly considered very great, are
altogether at a discount, and the only use to which
it is applied is in the preparation of perfumery.
I have said veiy little about the method of pur-
suit and capture of this species and of the Right-whale,
because it is a subject in which I take no pleasure ;
those who wish to know how these peaceful and
highly-organi/.ed giants are approached, and how
they behave when terrified and smarting under the
harpoon and whale-lance, can pursue the subject
ad nauseam in the pages of Scoresby, Bcale, and
others; the sickening process of "flensing" and
disposing of the blubber is described with equal
minuteness. I for one cannot appreciate the halo-
of romance with which some authors seek to sur-
round the whale-fishery. Doubtless the occupation
is one of hardship and danger, but the remunera-
tion when successful is in proportion, and I can
hardly conceive of men inflicting the fearful amount
of suffering which every "full" whaleship, or in
a still greater degree every "full" sealer, repre-
sents,— under any circumstances. Science is con-
stantly adding to our resources, and it is sincerely
to be hoped that ere long substitutes may be found
for animal oil and whalebone which will supersede
their use in the few processes in which they are
still requisite : should this be long delayed, it is to
be feared that the seals and whales, at least of the
northern seas, will soon cease to exist.
Although so widely spread over the waters of the
globe, possessing, I believe, a range greater than
any other known species of animal, it is only open
and deep waters which can be said to be the home of
the Sperm Whale ; and when found in shallow seas, its
generally emaciated condition indicates the absence
of its proper nourishment ; and the readiness with
which whole herds precipitate themselves stupidly
upon the sands, shows how little they are acquainted
with such objects. Mr. Andrew Murray makes some
observations upon this subject, which are so interesting
and so suggestive that I must ask you to excuse my
making a long quotation.
Speaking of those specimens which have now and
then been cast ashore in the North Atlantic or in the
English seas, he says : "They seem to be un-
prepared for, or not adapted for, shallow seas.
Accustomed (perhaps not individually but by here-
ditary practice or instinct) to swim along the coral
islands of the Pacific within a stone's throw from the
shore, they cannot understand, their instinct is not
prepared to meet, shallow coasts and projecting head-
lands. If they were habitual residents in our seas,
they must either be speedily extirpated, learn more
caution, or be developed into a new species." ....
Mr. Murray further says: "I observe that almost
every place that has been above mentioned as a
favourite resort of the Sperm Whales, although not
out of soundings, has claims to be considered the site
of submerged land. The islands of the Polynesia,
which are its special feeding-ground, are the beacons
left by the submerged Pacific continent. In pure
deep seas animal life is usually scarce, and the
absence of breeding-ground is probably the chief
cause of it ; but this only applies to a certain kind of
animals, those which require a bottom on which to
c 2

HA R£> WI CKE 'S S CIENCE - G OSS IP.
deposit their spawn ; but there are many which do
not require this. The spawn of some floats about
unattached ; for others a frond of weed is sufficient
attachment ; and it has occurred to me that the dis-
tribution of the Sperm Whale may in some way be
connected with the geological antecedents of the
ocean it inhabits. I think it not improbable that the
Fig. 12. Chair in Great Yarmouth Church formed of the
basal portion of the skull of a Sperm Whale (from Palmer's
" Perlustration of Great Yarmouth").
site of a submerged land may swarm with life, which
originally proceeded, or was dependent on it, long
after it had been in the deep bosom of
the ocean buried. The Sargasso seas,
which swarm with Eolidcr. and Crustacea,
are examples of this life : it is not invaria-
bly either present or absent in deep water,
and it is its presence or its absence which
is instructive. Those animals which re-
quired a bottom to spawn upon may have
died out or been developed into others
which do not ; and those which do not
require such a support may have multi-
plied correspondingly. In one of the maps
in Lieutenant Maury's book, already cited, there
is a space of sea opposite the western coast of South
in some way to it — might continue to linger over it
long after it had passed beyond the depth at which it
could practically have any effect upon the animal life
above it ; but if a part of the circumference of the
globe has always been under water, before and ever
since the creation of life, no life is likely to be found
on that spot, because it has never had a starting-point
of life from which to begin ; and, as already said, a
slender barrier stops the spread of species, and
species would certainly not spread to a spot where
there was nothing for them to feed upon. Again,
animal life could not begin to feed upon animal life
till vegetable life had previously prepared the way by
providing food for the animals which were to furnish
food for others ; and vegetable life could not begin to
grow without a foundation of land, accessible either
above or below water. The total and constant
absence of all life at any particular spot appears to
me, therefore, to furnish a presumption that there has
never been dry land or shallow water there. Whether

cause peculiar to itself, should be more desolate than
any other in the same latitude — than the deep sea on
the east side of Patagonia, for example. I can

may be answered, would not affect my explanation of
the cause of the absence of the Sperm Whale from
such spots."* I am indebted to the kindness of
Chas. J. Palmer, Esq., of Great Yarmouth, for the
woodcuts (figs. 12 and 13) representing the chair in
Yarmouth Church which is formed of part of the
skull of an individual of this species.
The sub-family Ziphiina, which follows next, is,
perhaps, the most remarkable of the whole of
this interesting order. The Zipkieid Whales, as
they are designated, are, with one exception,
very rare, and until the commencement of the
present century, with that one exception, were
known to science only from their numerous re-
mains, found chiefly in the Crag deposits. "Since
that time, however," says Prof. Flower, in his
memoirs of this group (Trans. Zool. Soc, vol. viii.
p. 203), "at irregular intervals, in various and most
distant parts of the world, solitary individuals have
been caught or stranded, now amounting to about
thirty, which by some naturalists are referred to
upwards of a dozen distinct species, and to very

nearly as many genera. No case is recorded of
more than one of these animals having been observed
in one place at a time, and their habits are almost
absolutely unknown. . . . This comparative rarity
at the present epoch," he farther says, "contrasts
greatly with what once obtained on the earth,
especially in the period of the deposition of the Crag
formations, and leads to the belief that the existing
Ziphioidsare the survivors of an ancient family which
once played a far more important part than now
among the cetacean inhabitants of the ocean, but
which have been gradually replaced by other forms,
and are themselves probably destined ere long to
share the fate of their once numerous allies or pro-
genitors."
The members of the group may be distinguished
at once by the absence of functional teeth in the
upper jaw : those in the lower jaw are always
quite rudimentary, with the exception of one, or
occasionally, two pairs. These may be largely de-
veloped, especially in the male sex, and are placed,
generally, well forward. The blow-hole is sub-
crescentic, and a pair of remarkable furrows occur
in the skin of the throat, almost in the form of the
letter V, the point directed forward. The skull
presents a remarkable appearance in the genus
Hyperoodoti) caused by the enormous maxillary
crests which produce the peculiar conformation of the
head in the living animal, originating the trivial name
"Bottle-head." The common Beaked Whale, or
Bottle-head (Hyperoodon rostratus, Chemnitz), is
of frequent occurrence in the North Atlantic, and
generally visits our shores in autumn, sometimes
ascending the estuaries of rivers : it has been taken
several times at the entrance to the river Ouse. It is
solitary in its habits, more than two are never met
with in the same place, and in that case it is often the
old female and heryoung one : the old male is said to
be very shy and rarely secured. In September, 1877,
an adult female, 24 ft. long, was taken in the Menai
Straits ; it was accompanied by another, probably
its young one. The colour is black above, the
under parts being lighter : the two teeth in the
lower jaw are generally hidden in the gum. Its
food consists of cuttle-fish, the remains of great
numbers of which have been found in its stomach.
Another species of Hypcroodon, H. latifrons, has
occurred three or four times on the British coast ;
it has also been taken in Greenland. Very little
is known about it as a species, and that only from its
bones : it is supposed to attain a greater size than
II. rostratus, probably upwards of 30 ft.
Cuvier's Whale {Ziphius cavirostHs, Cuv.),
another of this remarkable group, has been met with
once on the coast of Shetland, and it, or its remains,
have been found about five or six times in other parts of
Europe, and also, it is believed, at the Cape of Good
Hope, and the east coast of South America. It has
two teeth, one on each side the lower jaw, close to
the extremity. Cuvier established the genus Ziphius
in 1825, from a fossil skull found on the coast of
Provence, in 1S04, which he believed at the time to
belong to an extinct animal.

STRUCTURE OF SAND-HILLS.
By W. B. Grove, B.A.
LAST summer I had a very good opportunity of
examining the structure of the dunes on the
Lancashire coast. A copy (fig. 15) of a sketch, made
on the spot, may be interesting, as I can find none
in our common text-books which give an accurate
idea of it. It was taken from a natural section of a
hill about 14 feet high, half of which had been neatly
blown away by the wind. The irregularity of the
bedding, represented by the darker lines, is due to
Fig

changes in the direction of the wind, which, after
depositing a stratum, often sweeps away a part of
it ; and then, after another change, deposits fresh
material on the new surface. As the successive
laminae conform accurately to the varying outline of
Fig. 16. Sandstone Cliff, Suffolk (after Lyell).
the surface on which they are deposited, a series of
irregular beds is thus produced. This is often called
false-bedding. The same name is also applied to
diagonal stratification, in which the planes of the
lamina of sandstone are oblique to the plane of strati-
cation, as seen in fig. 16. But this latter structure
can only be formed, I believe, when a current of
water, carrying coarse sediment, meets with a sudden

check to its velocity, and lets its burden fall ; the
particles then arrange themselves at the proper
"slope of repose," which depends upon their size
and form. This can seldom or never happen to a
current of air on a large scale, and consequently
diagonal stratification will rarely occur in sand-
dunes.
My reason for repeating these well-known facts is
that, in J. Geikie's small "Geology," I find the
following passage: — "Sometimes the layers of de-
position in a single stratum are inclined at various
angles to themselves. This structure is called false-
bedding ; the laminae not coinciding with the planes
of stratification Hillocks of drifting sand fre-
quently show a similar structure, but their false-
bedding is, as a rule, much more pronounced." The
first two sentences of this passage contain slightly
different ideas, and must confuse the student's mind.
According to my observation, moreover, the state-
ment in the last sentence is not true, if he takes the
latter of the two definitions apparently given of false-
bedding, as he would naturally do. It is best not to
use the term false-bedding at all, but discard it, as is
done by Lyell and Jukes, in favour of the two, irre-
gular bedding and diagonal stratification. The latter
of these cannot be called by the rejected name, as it
is not the bedding but the lamination that is ab-
normal ; we may, indeed, apply the name to the
former, but we shall have to explain that false means
irregular in this case, and we do not gain much,
except the opportunity of writing a second sentence
to explain the meaning of the previous one.
THE CLASSIFICATION OF THE
FORAMINIFERA.
By W. K. Marriott.
THIS was the subject of a paper recently read
before the Metropolitan Scientific Association.
The author referred to the Eozoon Canadense, and
while giving a brief recapitulation of the arguments
in favour of its organic origin, he held it up as not
only the fust of all foraminiferous life, but also, in its
special capacity as a rock builder, as typical as the
very Globigerina itself. He considered as inimical
to the claims of the Eozoon that Messrs. King and
Rowney, the leaders of the opposition, had lately
received a grant from the Endowment of Research
Fund, for "Researches to determine the Structural,
Chemical, and Mineralogical Character of a certain
Group of Crystallic Rocks." If this were aimed at
the Eozoon, he was content to leave the matter in
their hands, feeling confident that its position in the
animal world was assured. After referring to the
utility of classification in general, he showed how
the classification of the Foraminifera had been
alternately neglected and over-indulged in ; how in
the one case it was left to itself, and in others had
been filled with synonymes, and how M. D'Orbigny
had rescued it, and how he again had spoiled it.
He then showed the system of the classification of the
whole Protozoic group, and how its two great
branches, the Rhizopoda and Ciliata, develope on the
one hand, through many stages, up to the many-
chambered Foraminifera, and on the other to the
Actinophrys and Vorticella. He regretted he could
at present do no more than indicate the great question
that lay open at this point, namely, how these two
developments of Protozoic life are related to the
supplementary groups of Polycystina, Thallassacollida,
and Spongiada, and to the Ichthydina and Noctilu-
cida. As the classification of the Foraminifera rests,
by reason of the simplicity of its animal matter, upon
no physiological basis, it remains very clearly that it
can only be upon the structural difference of its
shell ; this, again, being due to the hardening, with
only very slight modifications, of the outside of the
creature— the calcifying of its epidermis, as it has
been somewhat curiously called ; this classification
rests on very reasonable and simple grounds. The
necessity of the first great divisions into Monothalamia
and Polythalamia immediately suggests itself. The
Monothalamia, or one-chambered Foraminifera, con-
sists of three families. The first, and largest, in point
of genera, is the Lagynida, so called from the flask-
like shape of its members. Specimens were shown
under the microscopes in the table, and were found to
exhibit every variety of form of flask that ever left the
hand of the potter. This distinctive feature was also
shown upon the black-board ; indeed, Mr. Marriott
materially assisted his audience in understanding the
principles of the classification by sketching thereon
typical genera of all the families, giving the salient
points in the structure of the shell by which the
creature earned its name and position. The second
family, Orbulinida, has but one member, but this is
the interesting Orbulina that the Challenger Expedi-
tion has brought prominently to the front ; its points
of resemblance to the Globigerina were dwelt upon,
and also its curious divergences from that genus.
The third family, Comusfii ida, was then shown, and
its great apparent resemblance to our fresh-water
mollusk, the planorbis, at once fixed it on the mind ;
this concluding the Monothalamia. The grouping
of the Polythalamia was next shown, but here a
greater number of families are found, and conse-
quently intricacies of various kinds to be encountered.
The first group, the Helicoidea, contained every spiral-
shaped Foraminifera there was, and some, like some
of the members of the first family, that were not spiral
at all, but simply possessing more chambers than
one. These were the Miliolida, from their resem-
blance to millet seed. The second family, Turbi-
nida, possessed, with many variations, a shell like
the well-known mollusk Turbo, and specimens of
this family are found in all collections. A sub-
family of this, called, from its clustering and grape-
HA RD WICKE 'S SCIENCE - G OSSIP.
like form, the Uvellida, contains the world- famed
Globigerina. And another well-known sub-family,
the Textilaria, shows a curious conformation of a
spiral that produces the appearance of being woven.
Then comes the second great family of the Poly-
thalamians, the Natitiloidea, that led M. D'Orbigny
into the error of classing them with the Nautilus
and Ammonite. A reference to specimens showed
how far he was justified in this. The first sub-
family, the Cristellarida, the second Nonionida,
third Peneroplida, and fourth Orbientina, contain
well-known genera that, either in outward form or
inward structure of cell and segment closely mimic
the form of that great class from which more recent
investigation has banished them. The remaining
two families were then enumerated, and the Orbitn-
lita, as being the most interesting belonging to them,
was detailed, after which the Rhaboidea, the second
great group, or rod-shaped Foraminifera, was ex-
plained. This possesses but one family, the Nodosa-
rida, whose knot-shaped chambers, arranged one on
another, enables everybody at once to identify
them. This brought the classification to an end.
Mr. Marriott, in conclusion, passed on to the life
history of one of the Foraminifera as typical of the
whole of the class. He chose the Globigerina, because
round it has centered the most popular and scientific
interest and research, and gave the most recent
investigations and speculations on the subject.
A VISIT TO SPONSA'S HEADQUARTERS.
By H. C. Dent.
AFTER' reading the two papers on " Lepidoptera
of the New Forest" and "Sport in the New
Forest," our hopes were roused, and we arranged to
go] to that Elysium in the long vacation. As my
brother was not free till the first week in August, I
filled up some of the spare time in visiting Darenth
Wood, Box Hill, and Epping, in successful quest of
the spring species ; and at the end of June went for
three weeks to Switzerland, and visited its glaciers,
snow-peaks, and insect hunting-grounds. Here I
must wander, and give a few localities for those who
propose a trip to that glorious country next season.
The upper end of the Lauterbrunnen valley, near
Trachsellauenen (very good little inn) is a splendid
place. Here, while revelling in the sight of the
Jungfrau, Monch, and many other superb peaks, you
may take Machaon, Arion, Hyale, Cratcegi, Globu-
larics, Trifolii, Lonicenc, Grammica, two kinds of
large copper, and many foreign species of blues and
fritillaries ; on the Chaumont near Neuchatel, Apollo
and Podalirius abound (also the most atrocious and
pertinacious Diptera) ; at Grinclelwald I captured
four superb Machaons at one fell swoop ; the Nicolai
Thai — and in fact the Zermatt district generally —
with the vineyards above Saxon (Rhone Valley) well
repay a visit ; while at Gryon, near Bex, Dia and
other rare fritillaries abound ; besides Sinapis, Hero,
the Zygenida:, Szc.
To return. We arrived at Brockenhurst on August
8th, and put up at the "Rose and Crown" (pro-
prietor, James Ings), where we had, a week previously,
ordered beds. Nothing could be more cheerful than
our rooms, and during our whole stay we were most
comfortable, while the charges were reasonable. Affer
a good lunch, we sallied forth for a couple of hours,
and — considering that the weather was bad — obtained
a very fair "bag." In the evening, however, we
were not so fortunate, as we only took one Promissa
and a few Pyramided ; although the weather was
suitable, rarities would not appear.
The next morning we went through the Forest to
Lyndhurst, on the right side of the road for about
halfway, and then on the left. We saw innumerable .
Paphia — all more or less rubbed — two Sibylla, and
' ' buttered " a female Iris ! This splendid lady was
sipping the nectar from a bramble blossom, when
down came the net over her, but, alas ! her imperial
majesty quietly glided downwards through the thorns,
evading the death-dealing gauze, and soared triumph-
antly to the top of a neighbouring oak. This
damped our spirits, but they soon rose when we
captured two Argiolus and a pair of Qiiercus. The
latter we found very abundant at the tops of young
oaks ; so at length we devised a plan for their
capture, and having cut down a straight birch
" stick" of about 15 ft. long, and fixed a net at the
top ; after two days' practice we succeeded in taking
eighty specimens in less than a couple of hours ; the
abominable Forest flies tormenting us all the time
above measure. We saw daily a few Iris besporting
themselves above and around the high oaks, but they
were inaccessible.
From August 8th to 10th, the weather was unpro-
pitious ; as clouds, wind, and rain are not compatible
with fly-catching. However, as we liked the sylvan
beauties of the places we had visited, and as we feared
"to go farther and fare worse," our daily plan was
to start from the "Rose and Crown" about nine, go
through the Forest to Lyndhurst (about three miles
direct), where we arrived about one. Then after
lunching at the "Crown and Stirrup " (three minutes
from forest, proprietor Charles Pack, who lets apart-
ments), we returned through the Forest, arranged our
captures, dined, and set off for sugaring.
At length we were told of a place where Sponsa
was said to abound. "Some gentlemen 'uv took
fourty a noight this season," said our informant.
Thither we determined to go, and the following
evening (August 13th) we started, equipped with
bags full of empty pill-boxes, chloroform and cyanide
bottles, and corked boxes well stocked with No. 6 pins.
We arranged to sugar 150 trees, and keep on visiting
them till we were tired. We had sugared over 100
when an individual approached armed with a net, a
HA RD IV 1 CKE 'S S CIENCE - G 0 SSIP.
cyanide-bottle and a corked box. We tackled him.
"Any Sponsa about? Wy bless yer, 'eaps on 'em.
Thur's one on that thur tree now." Our blood was
up, we longed to dart at it, but it was that man's tree,
and we refrained. He told us he had taken 1 20 in
three nights, and that his usual nightly haul was from
twelve to twenty. We asked him how many trees
he " painted." "Wall," he said, "I begun doin'
about thirty, but w'en they're plentiful I doaint
have no time to look at more'n about six trees ; there's
ten on a tree sometimes." We were roused to mad
excitement ; in half an hour we had taken a dozen on
as many trees. Many flew off, and that night we
had no nets. It was now 8.30, and we met our
friend going home. " They're ovur for to-noight,"
said he. We stayed another half-hour, but took only
a couple on his trees.
Fig. 17. Dark-crimson Underwing Moth (Catocala s/>ousa),
The next night, having found that Sponsa flew
early, we sugared earlier, and before dark had taken
another dozen Sponsa, and two or three Promissa,
besides the rare Subseaua. We had intended going
to the Isle of Wight on the 15th for Hyale and
Helice ; but another Sponsa hunt was not to be
winked at. That night we captured twenty-one
Sponsa and two Promissa, while the multitudes of
Pyramidal were as usual a perfect pest.
To see whether any Sponsa are settled on sugar
needs some practice, when their wings are folded over
their backs — especially in the dusk — as the upper
wings resemble closely the bark of the trees ; when,
however, the wings are partly expanded — showing the
splendid crimson bands — I can hardly imagine a
more exciting sight ; the very thought of it makes me
thrill even now. Our mode of proceeding was to pill-
box the moths, pour in a drop of chloroform, and
when they were quiet, pin and remove them to the
corked box. When we got home they were stabbed
with oxalic acid. If they were too wary for the pill-
box or cyanide-bottle, we netted them, and then
pill-boxed. We thus found half a dozen pill-boxes
ample.
At length, on the 16th, we left Brockenhurst with
sad hearts, took the train to Lymington, and steamed
across the Solent, at the rate of four miles an hour,
under a hot sun, to Yarmouth, in company witli a
flock of sheep and a fat farmer, who was much
wrapped up and enduring all the agonies of sea-sick-
ness. We were greeted by numerous Rdusa, Cardui,
and Polychloros, besides innumerable Atalanta.
Having "humped" our knapsack, we .marched on
the west side of the Yar to Freshwater. Wishing to
be near the sea, we scorned the respectable Red
Lion Inn, and put up at the Albion, Freshwater
Bay, where we were duly charged next morning.
That afternoon we walked towards Alum Bay,
but a strong gusty wind prevented anything
more than a grand view from the beacon above
the Nodes, and the capture of a few Corydon
and Edusa. As the weather continued un-
favourable the next morning, and it was incum-
bent upon us to be in London by Saturday, we
threw over our plan of walking to Shanklin,
Ventnor,and Cowes, and determined to have
another evening at Sponsa 's headquarters. We
therefore went back to Yarmouth, where we
netted many Edusa, Galathea, Cardui, and a
hybernated Helice, and then returned to Brocken-
hurst. We were rewarded : over two dozen
Sponsa requited our endeavours before 7.45,
when the moon shone brilliantly, and the
underwings retreated to the tops of the oaks.
This brought our Hampshire expedition to a
close, and the next lepidoptera I saw — three
days after — were some Edusa, Io, Cardui,
&c, in the picture-galleries of The Hague,
Haarlem, and Amsterdam, calmly flitting
round and settling on bouquets which, though
painted a couple of centuries ago by Mignou,
Ruysch, and others, still retain much of their original
freshness.
The following is a list of thirty-one diurni
we saw in the New Forest : — Rhamm, Edusa,
Brassicie, Papa, Napi, Galathea, sEgeria, Ilyper-
antlius, Megara, Semele, Tithonns, Janira,
Pamphilus, Sibylla, Atalanta, Io, Polvehloros,
Urtiae, Cardui, Iris, Quercus, Betuhe, Adippc,
Aglaia, Paphia, Phleas, Argiolus, Alexis, Artaxerxes,
Sylvanus, and JJuea. We were informed that
this year had been bad for Valezina, and especially
for Sibylla. Of the latter we only saw half
a dozen, while ten days before they were abun-
dant in Fssex. Orion and Balis had been
plentiful.
HARD WICKE'S SCIENCE- G OSS I P.

A PLEA FOR THE MICROSCOPE AS
A TOY.
IT 7E are °ften reminded that the microscope is
V V no longer a toy, but a scientific instrument,
and those who use it for recreation only are not un-
frequently hard hit, as mere wasters of time and
desecrators of a noble power.
Now, while fully appreciating the scientific use of
the microscope, I would suggest a slight alteration in
the above dictum, and say, it is not only a toy, but
a scientific instrument. I would plead for it as a
source of amusement. The President of the Quekett
Club, in his recent address, reminds us of a remark
in the first page of the "Microscopic Journal" of
1841, where it is said of microscopic research in those
days, that it "is for the most part an amusement
rather than a profession" — it is an "intellectual
pastime, which is sure to terminate in beneficial
results. General knowledge may be acquired by
observation," and this " by industry and perseverance
imperceptibly produces recondite science." This is
just the view I would take of microscopical employ-
ment. It is first an " intellectual pastime." Wearied
in body and mind the man of business or of litera-
ture seeks rest. Some find it in mere lounging in an
easy-chair, and joining in the family chit-chat ; others
in listening to the music which a wife or daughter
elicits from the pianoforte. There is no objection to
this ; but if the taste leads to the observation of
nature in the sky, the earth, the sea, then a special
interest is felt in whatever tends to reveal the secrets
of that existence by which we are surrounded. Some
turn to the telescope, others to the microscope, not
as a means of scientific research, but as "an intel-
lectual pastime." Investigation requires powerful
effort, both of mind and body. Few have this to
expend now-a-days on what does not bring grist to
the mill. The mind wants recreation, as the appetite
longs sometimes for change of diet and enjoys the
dainty bit. The holiday keeper rushes into the
country, not to study, but to enjoy, its beauties. He
visits the picture gallery, not to become an artist, but
to satisfy a taste. He goes to the British Museum or
the Zoological Gardens not to become a naturalist,
but to enlarge his ideas. He cultivates a variety of
sweet and pretty flowers in his garden, not with the
remotest intention of becoming acquainted with their
orders and relationships, but purely for the enjoy-
ment to be derived from them. And why may a
man not use his microscope in the same way ? What
wonders — what beauties — does it reveal ! Well has
it been said that the microscope is a door into another
world. It is so, and the man who uses it merely as
such is amply rewarded. The door is opened and he
is almost bewildered with the variety and beauty of
what he sees. His mind is enlarged, his views are
corrected ; his taste is charmed, his wonder excited.
The whole man is elevated, refreshed, and invigo-
rated. It is not only a pastime, but "an intellectual
pastime."
But, further, we are told it is "sure to terminate
in beneficial results." This " intellectual pastime,"
then, does not as a rule stop there. It is not a lovely
vision which vanishes away, but is an avenue to a
brighter and broader view. It induces the habit of
observation, and surrounds even the least things with
a halo of interest which they could never otherwise
have possessed. The smut on the ear of corn — the
disease of the leaf of the potato — the mould on the
cheese — all are now full of interest. The most un-
promising object often exhibits a most unexpected
character, or reveals a long-looked-for secret. And
thus the mind is not only refreshed but stored with a
new fact, which in its turn proves to be only the
cradle of another : so, step by step, the " beneficial
results " are evolved. And great as these are in an
educational and abstract point of view, they are by
no means wanting in a practical, as the application
of the microscope to physiological, histological, and
commercial subjects, abundantly proves.
Let us begin, then, by play. If it ends here it is
at least as innocent and pleasing as any other — let
some of us begin by using our microscopes as toys,
let others use them so sometimes, for the amusement
of the uninitiated— it is "an intellectual pastime
which is sure to terminate in beneficial results."
This toy, moreover, is not an expensive one, either
to begin with, or to keep going. If you buy a gun
there is the annual licence, and the constant supply
of ammunition. If you buy a horse, the first outlay
is nothing compared with the keeping of it. But
when once you are provided with a microscope, there
is no tax to pay, no food required. Let this be a
plea for getting a fairly good instrument at first,
capable of being added to as required. Even the
magic-lantern soon tires unless new slides, which aye
very costly, be continually added. Having, then,
this toy, we learn to find objects which cost us
nothing, but, on the contrary, contribute largely to
our pleasure and profit. It has, too, a great
advantage over the telescope. You have not to wait
for cloudless nights, nor to run the risk of colds and
neuralgia. Every night is a microscopical night, and
the long dark evenings of winter may be not only
■beguiled but improved. — T. R. J., Codicote Vicarage.
PARASITES ON FISH.
By John Davis.
THE subject of the various parasites found en
fish has not hitherto received much popular
attention, except in Van Beneden's " Animal Mess-
mates." It is hoped, therefore, that the following
description of three of such parasites may induce
other naturalists to contribute further information on
this subject to the pages of Science-Gossip:

infests its back). — The tail is composed of two tubes,
finely marked, which commence at the end of the
animal at each side, and gradually narrow until they
meet. These tubes are nearly as long as the body.
The Gurnard [Trigla hirundo) has parasites :
this one was taken from the eye, to which it fastens
itself by the large wheel-like sucker ; it then bends
its body until it brings the small rings at the end of
the animal on the fish, and so jerks itself along. I
have drawn one end of the large sucker, as seen undei

of the animal) can be traced from the eyespots to the
stomach. The latter is composed of a spiral arrange-
ment of tubes, and marked with cross-lines, the same
as the antenna of the Lobster. It is a pretty sight
to watch the circulation in these vessels. At the
dorsal end is a rather large cavity, which I take to
be the ovary. The size of this parasite is -f'$ x -fa,
and examined through a 3-inch objective. It was
taken from the back of the fish.

WHITE MITES.
DURING the month of June, 1877, whilst driv-
ing in the countiy, I observed a black poplar
tree evidently suffering from the ravages of insects ;
I therefore stopped the vehicle, and got out to ex-
amine. I found the tree bored in many places by the
larva; of the Goat-moth (Cossus ligniperdd), three of
which I secured. A considerable portion of the bark
was loose, and the sap kept this quite wet, the
peculiar smell produced by the larva? being very
evident. On removing a portion of the bark where
it was moist with sap, I found it covered with a
moving mass, consisting of myriads of very peculiar
White Mites. On examining them under the micro-
scope, I found them to differ from any Mites I had
ever seen, nor could I find any notice of similar ones
in any work to which I could refer. The females,
which were in the greatest abundance, were egg-
shaped, the larger end being in front, and the sides
towards the posterior, somewhat bent in. On slightly
compressing them, they were seen to contain eggs.
The abdomen was of a milk- white colour, and the legs
reddish-brown. On crushing one of the Mites con-
taining eggs, one or two young ones escaped from the
almost mature ova ; these had only six legs, one of
the hind pair being missing. The males, which were
few in number compared with the females, were very
peculiar in appearance ; their bodies were less in size,
flatter, and the legs longer and stouter in proportion
than those of the females ; the posterior pair not used

for walking, but stretched out backwards, their ex-
treme ends bent inwards, and, as far as I could make
out, not furnished with claws. Their gait was ex-
tremely awkward. In certain Dermaleichi, found on
small birds, the males have one of the hind pairs of
legs very largely and peculiarly developed, but in
their case it is the third, the fourth pair being very
small, and used in walking.

About the middle of August I again visited this
tree, and found upon and with the White Mites a
number of Hypopi, but whether these were parasitic
on the White Mites, or merely residing with them,
I was not able to determine. I passed this tree
on several occasions during the summer, and fre-
quently saw Wasps and Red Admiral Butterflies
enjoying the sap, which kept some parts of the
tree continually moist. The figures are all drawn
from mounted specimens under a §° object-glass,

THE HISTORY OF OUR SALAD HERBS.
Part III. — Mustard.
MUSTARD was, according to the belief of the
ancients, first introduced from Egypt, that
country which claims the honour of being the birth-
place of Ceres, the goddess of seeds, and ^Esculapius,
the god of medicine, through whose means this plant
was made known to mankind as an agreeable and
wholesome herb in its green state ; while the seed
was used as a medicine, and occupied the first rank
among alimentary substances which exercised a
prompt influence on the brain. Mustard is mentioned
by Pythagoras, and was employed in medicine by
Hippocrates, B.C. 480. Pliny states that there were
three kinds of mustard cultivated in his day ; the first
of a thin and slender form, the second with a leaf
like that of the rape, and the third with that like the
rocket. The best seed, he says, was imported from
Egypt, but that this plant grew in Italy without
sowing. The Romans made great use of the seed in
medicine ; the oil extracted from it, mixed with olive
oil, was used by those who suffered with stiffness of
their limbs after a cold bath. Pounded with vinegar
it was employed as a liniment for the sting of serpents
and scorpions, and a dose of it effectually neutralized
the poisonous properties of fungi. The Romans, and
other nations after them, used to ferment mustard-
seed in new wine, which converted it into a kind of
inferior brandy, and was known by the name of
Must urn aniens, burning wine.
The mustard-seed mentioned in the Scripture has
of late years been a matter of considerable controversy,
some authors supposing it to be quite a different
plant from the one we are now treating of ; but it is
generally believed by the best authorities in the
present day that the plant referred to was Sinapis
nigra, the common mustard, which is indigenous to
Palestine, as it is to Britain. Dr. Thompson, in his
" Land and the Book," records that he has seen
this plant as tall as the horse and his rider in the rich
plains of Acre.
36
HARD WICKE'S SCIENCE- G OSS I P.
" As small as a grain of mustard-seed," appears to
have been a proverbial expression for any small object
among the Jews ; and this seed, which was the
smallest the husbandman was accustomed to sow,
produced the largest results by becoming the greatest
of the husl landman's herbs.
We have no record when mustard was first used in
this country, but in the household accounts of the
thirteenth and fourteenth centuries we find that
mustard was known to our forefathers under the
name of " Senapum," and appears to have been used
in large quantities, for in that interesting Household
Book of the Earl of Northumberland, in the reign
of Henry VII., it is stated that 160 gallons of
mustard-seed was the allowance per annum to his
servants and retainers. In those days the seed was
not manufactured, but brought to table whole, when
it was bruised and mixed with vinegar, according to
the taste of the eater. It was not only used as a
condiment, but also, no doubt, for medicinal purposes.
Tusser, who wrote his "Five Hundred Points of
Good Husbandry " in the reign of Queen Mary, says,
in the direction for February, — ■
"Where banks be amended or newly upcast,
Sow mustard-seed after a shower be past."
From this it appears that mustard was cultivated as
a field crop ; we also find it mentioned as an agricul-
tural produce in Rogers's " History of Agriculture and
Prices in England," as far back as 1285. It must
then have been S. nigra, black mustard, or S. arvensis,
the charlock, for Gerard tells us that the garden
mustard, which produces the whitest of seeds, had not
become common in the days of Queen Elizabeth, but
that he had distributed the seed into different parts
of England to make it known. He says, "Mustard
makes an excellent sauce, good to be eaten with gross
meats, either fish or flesh, because it promotes diges-
tion and sharpens the appetite." Thomas Cogan,
M.D., of Manchester, who published his "Haven of
Health " in 1605, says, "The force of the seed is well
perceived by eating mustard, for if it is good in
making to weep we are straightway taken by the nose
and provoked to sneeze, which plainly declareth that
it soon pierceth the brain. Wherefore as it is a good
sauce and procureth appetite, so it is profitable for
the pulse, and for such students as be heavy-headed
and drowsy, as if they would fall asleep with meat in
their mouths. And if any be given to music, and
would fain have clear voices, let them take mustard-
seed in powder, work the same with honey into little
balls, of which they must swallow one or two down
every morning fasting, and in a short time they shall
have very clear voices." Shakspeare mentions mustard
as a condiment in his play, "Taming the Shrew," act
vi. , scene iii. , where Gi itmio says to Katliarina, ' ' What
say you to a piece of beef and mustard?" It is also
mentioned in his play " As you like it," in connection
with pancakes (see scene iii.). In Evelyn's time,
Tewkesbury was famous for its mustard. The seed,
Coles tells us, in 1657, used to be ground there and
made up into balls, which were brought to London
and other remote places as being the best the world
affords. Mustard used formerly to be largely culti-
vated and manufactured in the county of Durham ;
but until the year 1720 the seed used to be pounded
in a mortar and coarsely separated from the black
integuments of the seeds, and in that rough state
prepared for use. About the year mentioned an old
woman of the name of Clements, resident at Durham,
conceived the idea of grinding the seed in a mill, and
to pass the meal through the several processes which
are resorted to in making flour from wheat. The
secret she kept for many years to herself, and in the
period of her exclusive possession of it supplied the
principal parts of the kingdom, and in particular the
metropolis with this article ; and George I. stamped
it with fashion by his approval. Mrs. Clements used
to travel twice a year to London for orders, and was
able to pick up a small fortune. From this woman's
residence at Durham, it acquired the name of ' ' Durham
mustard" (Mechanic's Magazine, vol. iv., p. 87).
The seeds of Sinapis arvensis, charlock, and Kaphanus
raphanistrum, the wild radish common in our corn-
fields, are often sold and used as a substitute for
mustard-seed. The seed of the black mustard, like
that of the wild sort, and also of the wild radish, if
sown below the depth of three or four inches, will
remain in the ground for ages without germinating :
hence when once introduced it is difficult to extirpate.
Whenever they throw the earth out of their ditches
in the Isle of Ely, the banks come up thick with
mustard, and the seeds falling into the water and
sinking to the bottom will remain embalmed in the
mud for ages without vegetation (Loudon's "Ency-
clopaedia of Agriculture ").
Sinapis alba appears to be a native of the more
southern countries of Europe and Western Asia. It
is now cultivated not only as a garden herb, but is
grown very largely as an agricultural crop, chiefly as
food for sheep or to be ploughed in for manure in its
green state. Mustard is extensively cultivated in the
Fen lands of Lincolnshire and Cambridge, also in
Essex and Kent. Its medicinal properties are well
known ; in its action it is an irritant, stimulant, emetic,
and stomachic.
Some authors think Sinapis is derived from sino to
hurt, and opts the eyes, from the pungency of the
plant causing the eyes to water ; others from the Celtic
nup (modern Gaelic neup) a turnip which belongs
to this tribe. Our word "mustard" is derived from the
French moutarde, but in early times it was, both here
and on the Continent, sauve or senevi. Some
authors assert that the etymology of this plant was
changed from the following circumstance. In 13S2
Philip the Bold, Duke of Burgundy, was marching
against his rebellious subjects of Ghent, and the city
of Dijon, which traded largely in senevc, supplied
him with a thousand men-at-arms, for whicli service
HARDWICKE'S SCIENCE-GOSSIP.
37
the Duke granted that city many privileges, amongst
others that of bearing his arms, with his motto ' l Moult
me tarde" in old French (I long or wish ardently),
which was carved on the principal gate of Dijon.
By some accident the middle word was destroyed ; the
other two, moult tarde, caused many a smile at the
expense of the citizens, and in derision the seneve
in which they traded was called mourtarde, a name
it has preserved ever since.
MICROSCOPY,
ACTINO-CYCLUS BERKLEY!. — I have some speci-
mens of this diatom, with reference to which I shall
be glad if one of your correspondents will give me a
little information. I should like to know, in the
first place, whose nomenclature A. Berkley is; and,
secondly, whether it is synonymous with any of the
species described in the fourth edition of Pritchard's
"Infusoria"; if not. where are the specific cha-
racters to be found ? — C. V. S.
Researches among the Sponges. — In the last
number of the "Annals and Magazine of Natural
History " there appear several important articles on
the structure of various kinds of sponges. W. Saville
Kent commences with one on " Professor Ernest
Haeckel's group of the Physemaria, and on the
affinity of the Sponges." W. J. Sollas describes
two new and remarkable species of Cliona. There
is also a paper by C. Mereschkowsky, on Wagnerella*
a new genus of sponge allied to the Physemaria of
Ilaeckel.
Mounting Marine Alg.e. — Mr. H. F. Atwood,
of Chicago, gives the following account of his
method of mounting alga?, in the November number
of the " American Journal of Microscopy." Mr. At-
wood advocates the use of salicylic acid, and
says — "My process is as follows: by using sea-salt
(which can be bought for a trifle at any first-class
druggist's) and distilled or rain water, a good sub-
stitute for sea-water is obtained ; into this I im-
merse the rough-dried specimens of alga?, and in an
hour or two they have resumed their natural shape.
Now, picking out and clipping off such pieces as
are best adapted for mounting, I transfer them to a
bowl of distilled water, and wash them clean, and
from thence transfer them to a small saucer con-
taining a saturated solution of salicylic acid. The
shallow cell into which they now go is built up of
shellac cement, made by dissolving bleached shellac
in Cologne spirits. Cells made of this substance are
ready for use twelve hours after being laid on to the
slide. I pick up the specimen with forceps, put it on
the slide, and fill up the cell with the salicylic acid.
I now breathe on the covering glass, and put it in
its place, and by the use of blotting-paper absorb the
superfluous fluid. A thin coating of gold size com-
pletes the work for the time being ; in a day or two
I lay on more gold size, and afterwards white zinc
cement or Brunswick black ; the finish, of course,
being a mere matter of fancy. In mounting a piece
of alga; having Isthmia parasitic on it, it is almost
impossible to fill these diatoms if balsam is used,
whereas by the use of salicylic acid every valve will
be filled. In some cases the medium I have used
has robbed the alga: of its colour, but this occurs
but rarely. I have a slide of Ptilota hypnoides in
full fruit, the beauty of which could never be brought
out except by first immersing the specimen in the
sea-water I have referred to. For the study of
alga:, direct light should be used, but using dark
field illumination is the best way."
The Quekett Microscopical Club. — The last
number of the Journal of this well-known and useful
club contains an address by the President, Mr. Henry
Lee, F.L.S., and a paper by Mr. W. K. Bridgman,
on "The Ordinary Condenser Improved, or 'Cir-
cular ' Illumination Superseded."
Coloured Oysters. — The oysters of the cele-
brated Arcachon beds having last summer acquired a
peculiar violet colour, the cause has been inquired
into by M. Desconst, who finds it was due to the
exceeding abundance of the highly-coloured spores of
a sea-weed {Rhytiphhva tinctoria). The colouring
matter of these spores had been assimilated by the
oysters, and retained by them, the extreme drought
of the summer months having favoured the operation
by reducing the water until it was not sufficient to
dissolve the colouring matter.
The Spore-producing Power of Fungi. —
At a recent meeting of the Linnean Society, Mr.
Worthington Smith exhibited drawings of Boletus
subtome>itosus, and stated that in a specimen five
inches in diameter, there are 17,000 pores, or tubes.
Each pore when cut across shows 2,000 cells on the
surface. The number of surface-cells on the under
side of a specimen is 36,000,000. The cells in ar.
entire plant are calculated at 615,000,000,000 ; and
the number of spores produced by the same specimen
are 5,000,000,000.
Parasitic Alg.l. — Professor Percival Wright has
described a new species of Chytridiacea' under the
name of Rhizophydium Dicksonii. It was found
parasitic in the cells of a sea-weed [Eetocarpus granu-
losus), and it is believed that the so-called " utricular "
fruits of Harvey, and the "spores" of Kiitzing, are,
in the Eetocarpus at least, in reality parasitic
Chrytridia.
Carnivorous Slug. — No doubt the slug which
your correspondent in the November number (p. 260)
saw feeding on a worm was Testacella Mangel, of
which a full and interesting description is given on
page S9 of Science-Gossip for April, 1S67. — JV. R.
Tate.
HARDWICKE'S SCIENCE-GOSSIP.
ZOOLOGY.
The Popular Science Review commences the
new year well. Besides a capital summary of scien-
tific progress, and many well-written and very fair
reviews, there are articles as follow: — "On some
Armour-plated Fishes," by II. Woodward, F.R.S. ;
"The Old and the New Chemistry," by M. M.
Pattison Muir, F.R.S.E. ; "The Geological An-
tiquity of Flowers," by J. E. Taylor, F.G.S. ;
"Cloud Outlines," by Rev. S. Barber, F.M.S. ;
"The Extinct British Wolf," by J. E. Harting,
F.L.S., &c.
New Australian Marsupial. — Professor Owen
has recently described a new marsupial animal from
Australia, under the name of Plcopus nudicaudatus.
It is a small creature, allied to the Kangaroo-rats,
but distinguished by having the type number of
mammalian toes (five) on each of the hind feet.
The Furniture Beetle. — F. Hughes cannot
do better than rub the furniture affected by this pest
with carbolic acid, and let the latter soak into the
wood. He will see no more of the beetles after
this treatment. — A. Smith.
Glyciphagus palmifer. — I was staying for a few
days at Christinas in a country house at Austrey, in
Warwickshire, and one wet morning it struck me that
I would brush the wall of the beer-cellar, and have a
microscopical examination of the result. I was
rewarded by finding a considerable number of the
extraordinary mite Glyciphagus palmifer. — At the
time of the publication of Mr. Murray's late work on
theAptera (where this insect is figured) this remarkable
species does not appear to have been known as an
inhabitant of this country, although Mr. Murray
anticipates that it may be one. Possibly, therefore,
this may be the first instance of its capture here. —
Albert D. Michael.
The Beaked Whale. — In the last number of
the Zoologist there is a capital description by Mr.
Henry Lee, F.L.S., of the Beaked Whale, Hyperoodon
rostratus, killed last September in the Menai
Straits, and afterwards publicly exhibited at Bangor.
This species is one of the Ziphioid Whales, an inter-
mediate group between theCachelotsand the Porpoises
and Dolphins ; and it is characterised by having its
teeth reduced to a single rudimentary pair at the tip
of the lower jaw.
Mimicry in Insects. — At a recent meeting of
the Entomological Society of London, Prof.
Westwood gave an account of a remarkable Mantis
(Gongylus gonegyloides) which mimics a flower, the
deception being supposed to attract the insects upon
which the Mantis feeds, to their destruction.
Notes on rare Lf.pidoptera, &c. — Referring
to Mr. Molony's note in October Science-Gossip,
on the occurrence of C. Celerio on Aug. 29, Mr.
Stainton, in the "Manual," gives October as the
month for the perfect insect to appear, and Mr.
Molony is, therefore, right in his statement of its
being early in its appearance. It is a curious fact
that though Colias Edusa has positively swarmed on
the S.E. coast this summer, very few rare Helice have
been taken, and its congener Hyale has not been seen
there, but has occurred quite inland. Mr. S. Machin
took (last August) a very fine specimen of C. Hyale'vsx a
wood near Henley, Oxfordshire. Last yearl find among
my specimens of Heterocera a fine one of Acronycta
tridens, taken in Hillgrove-road, Avenue-road, N.W.
The occurrence of this species near London, I believe,
is unusual. September 13th, two specimens of Edusa
seen in a street leading to the Hampstead-road (viz.,
Frederick-street), and I last saw it in Regent's Park,
on September 15th. Since then it seems to have
disappeared. It will be interesting to note if it ap-
pears again this year on any fine, mild day. — R. T.
Gibbons.
Plants for Reptile Vivaria. — Probably the
only plants which would succeed in a Reptile case
are succulents, such as Sedums and small Semper-
virjums. These, I know, will flourish ; but my slight
experience tells me that it is better to consider plants
as entirely secondary objects in a vivarium of any
kind, and in Reptile cases to do without them alto-
gether. I experience but little difficulty in the winter
with respect to food. Mealworms can be obtained
from the miller's, and kept in barley-meal as long as
one pleases ; common earth-worms are also useful ;
while, in order to secure flies during the winter
months, I place fly-blown meat in a tightly-closed
box, having bran at the bottom two or three inches
deep. I place the box in an outhouse, and supply
fresh meat twice a week, till the worms become
chrysalides or gentles. Then I remove the box to
the coldest part of the house, till flies are required,
which I can obtain by taking a few of the gentles to
a warm room for a day or two, so as to hasten the
hatching process. Sometimes, however, the flies will
hatch out, in spite of all precautions, in which case
I keep the flies in the same box, and feed them with
fruit and sugar and water. — IV. T. H. C. Trome.
Badly-blown Eggs and Preserving Animals.
— I should recommend " G. T. B." to try a solution
of carbonate of soda for dissolving out the hardened
contents of his egg-shells. He must take care to
wash the inside of the egg well with clean water
after using the carbonate of soda, and to prevent its
coming in contact with the outside of the shell.
"W. G." will find a chapter by Mr. Waterton on
preserving insects for the cabinet, in the 1839 edition
of his "Essays on Natural History," p. 72. Mr.
Waterton also gives instructions for preserving birds'
eggs, p. 65, but I should not recommend their adop-
tion. In a chapter at the end of his celebrated
HARD WICKE 'S SCIENCE- G OSS IP.
39
"Wanderings in South America" (1S25 edition),
Mr. Waterton fully explains his mode of preserving
birds ; the process is very tedious, but the result, as I
can testify, is very beautiful. Both this process and
that of preparing insects would be too long to give an
account of here. — T. S.
Preserving Animals.— The basis of Waterton's
proceedings was the preservation of his specimens by
the use of bichloride of mercury dissolved in alcohol.
This hardens the skins and causes them to retain the
shape in which they are placed when wet for any
length of time : thus no wires are necessary.
" W. G." will find the whole process most minutely
described in "Waterton's Essays on Natural History,"
new edition, F. Warne& Co., price 7s. 6d. — W. B. R.
Preserving Animals.— The late Mr. Waterton
had a peculiar mode of his own of preserving animals,
an account of which will be found in his life by Mr.
Hobson. It is not, however, by any means,
equal to the present mode by a skilful artist of setting
up birds. If " W. G." wants a ready way, let him
eviscerate a bird, place it in the position he wants, and
then fill it with cotton soaked in carbolic acid
dilute ; and the bird will be preserved for ages. This
does not do, however, and is given up for the
skinning process. — C. R. Bree, M.D.
Later Appearance of the Hirundinid/E. —
"R." will be interested to hear that I have in my
possession the nest and one egg of Hirundo rustice
{Chimney swallow), which was taken while the bird
was sitting ; she having been duly watched when
building in a cart-shed at Walton-on-the-Naze, in
December, 1S66. See Field, January 12th, 1867. —
C. R. Bree. M. D.
Badly-blown Eggs.— Let " G. T. B." get Prof.
Newton's little Essay upon blowing and preserving
birds' eggs, which he can buy for a shilling or so, and he
will get all the information he wants. — C. R. Bree,
M.D.
The " Midland Naturalist." — It is with much
pleasure we welcome this new literary labourer into
the field of popular science. Like the Scottish Natu-
ralist (which relates chiefly to the Natural History
of Scotland) and The Naturalist (the organ of the
West Riding Natural History Societies), the Midland
Naturalist purposes to give preference to local
scientific information, and to chronicle the doings
of the numerous energetic clubs and societies which
are springing up in central England. Among these
are the following : — Various societies in Birmingham,
Burton, Caradoc, Dudley, Derbyshire, Leicester,
Northampton, Nottingham, Rugby, Oswestry,
Severn Valley, Shropshire, Stroud, Tamworth, &c.
The first number of the Midland Naturalist appeared
on January 1st, and appears with an attractively
got-up cover designed by Worthington Smith. It con-
tains well-written articles on Ferns, Meteorology,
Zoology, and Geology.
BOTANY,
Further Notes on the Flora near Cader
Idris. — Seeing from the "Botanical Notes in the
Neighbourhood of Cader Idris," and also from
another correspondent in the September number, that
there are some of your readers interested in the plants
of that neighbourhood, I should like to mention a
few more to be found there, in addition to those
already specified : — Saxifraga stellaris ; Melittis Me-
lissophylhtm (bastard balm) ; Impatiens noli-me-
tangere (yellow balsam) ; Ranunculus Lingtta (great
spearwort) ; Sedum telephium ; Euonymus europaus
(spindle tree) ; Asperula odorata (woodruff) ; Ruscus
aculeatus (butcher's broom) ; Narthecium ossifragum
(bog asphodel) ; Myrica Gale (bog myrtle) ; Lobelia
Dort/nanna, found in Llynn Creigenau, and also in
Llynn Cyri, another lovely little tarn not far off,
nestling close in under the mountain. Nearer to the
sea I found Eryngium maritimum (sea holly) ; Aster
Tripolium (Michaelmas daisy)'; Statice Limonium (sea
lavender) ; Crithum maritimum (samphire) ; Silenc
maritima (sea campion) ; Rosa spinosissima (burnet-
leaved rose) ; Tanacetum vulgare (tansy), found at
Llangrwyll, a village four miles south of Arthog.
Aspleuiuni maritimum grows on the cliffs between
these two places ; and to the list of Ferns I can also
add, having | found Asplenium viride and Hymcno-
phyllum tunbridgense on the Llynn y Gader side of
Cader Idris. These plants were found in the month
of August, during a week's stay at Arthog, a village
on the Dolgelly side of the estuaiy, nearly opposite
to Barmouth ; and the district through which they
range is included in walks the farthest point of which
reaches Llynn Gader in one direction, and in another
stretching along the coast three or four miles south of
Arthog. — A. Warner.
The Watford Natural History Society. —
The eighth part of the " Transactions " of this
vigorous society contains a capital paper by the
Rev. George Henslow, F. L. S., on "The Fertiliza-
tion of Plants," and another on "Instructions for
taking Meteorological Observations," by William
Marriott,iF.M.S.
The Influence of Trees on Rainfall. —
From observations by M. Fautrat, relative to the
comparative influence of leafy woods and resinous
woods on rain and the hygrometric state of the air,
recently communicated to the Paris Academy, it
appears that pine forests have a much greater influ-
ence on the hygrometric state than others ; so that if
the vapours dissolved in the air were apparent, like
fogs, we should see forests shrouded in a large screen
of moisture, and in the case of resinous woods the
vapoury envelope would be more distinct than in that
of leafy woods. M. Fautrat also shows that pines
retain in their branches more than half of the water
which is poured upon them, whereas leafy trees allow

fifty-eight per cent, of the precipitated water to reach
the surface of the ground. He suggests, therefore,
that in planting with a view to oppose inundations, it
would be advisable to choose by preference resinous
trees, as offering a better covert.
Gentiana acaulis in Wales. — As one of the
correspondents who felt doubtful as to the occurrence
of Gentiana acaulis on the Cader, may I be allowed
to say the doubt has not been removed ? My personal
authority about the Cader is of little use, since when,
as a boy, I ascended it I was more fond of Lepidoptera
than flowers, but I have a distinct impression of
seeing a Gentiana there, but neither acaulis nor
amarella, but campestris. I see this latter is included
for Merioneth in "Topographical Botany," though
Mr. Ley does not mention it in his list ; but as this list
is principally of such plants as are not mentioned in
" Topographical Botany," it does not follow that he
failed to observe it. The habitat of campestris, as
given in Hooker's "Student's Flora," is moist,
especially hilly pastures, ascending to 2,400 feet in
the Highlands. I have gathered it on Ben Lawers
at i,Soo feet, where it is not at all uncommon on
sub-Alpine slopes, and though campestris is very
unlike acaulis, yet I would respectfully suggest if this
might not be the gentian that was noticed ;* anyhow
the discussion will probably lead to a more thorough
search of the Cader shortly by some of your readers.

hurricane of the 14th October has swept away its

British Marine Ai.o.l. — A correspondent of
mine, resident in St. Helier's, Channel Islands,
writes me that a short time since, a considerable
number of the singular sea-weed Gigartina Teeaii,
had there been washed ashore, some of the specimens
very fine, and a few of them fertile ; this plant has
not been discovered on any of the British shores for

Botany is that of Moris, de St. Amans, who found it near
Haverford-w est, where, without doubt, it was a garden escape.
upwards of fifty years. I have received a few of
these specimens also from the French coast, and
believe it to be tolerably abundant on the coast of
Normandy, and southwards along the west shores.
I last year visited Weymouth, and there on the sands
picked up a few very interesting specimens of Gigar-
tina pistillata in fruit, and also found two or three
fronds in very bold form of Graceolaria compressa.
From that town I proceeded to Bournemouth, and
was there fortunate in discovering two specimens of
Dasya pumicea, which appears to have been absent
from our waters for some years. The shore of
Torpoint, Plymouth, is very celebrated for receiving
from its adjacent waters many very beautiful sea-
weeds ; amongst its number I last year found in some
abundance the very pretty weed Niliphyllum Tliy-
sanorhizans, some of the specimens in fruit. I also
found it in the same locality in the year 1S73, and in
fruit, and the somewhat scarce plant Dudrisina dudri-
snagra also came before me on the same shore. —

AsrLENiUM Sei'TENTrioxale. — I can confirm
what your correspondent, Mr. Belt, says as to Aspic-
niton Septenttionale being found near Uolgelly ; my
friend Mr. Rose, of Gorton, and I saw it growing
there in the summer of 1874 (but sparingly), and
we did not even bring a frond away. — T. Brittain.
Solanum Dulcamara. — My impression, after
reading a great many articles about this plant, is
that the bulk of evidence points to the berries as
being innocuous, or nearly so. In Pereira "Materia
Medica " (edited by Bentley and Redwood), the
following account of the properties of this plant is
given: — -"Physiological Effects, not very obvious.
It is reputed to operate as a diaphoretic, diuretic,
and demulcent, and in overdoses as an acro-nar-
cotic ; but many have given the fruit and prepara-
tions of the young branches in very large doses,
without any obvious effects." The dried young
branches are used in medicine, and used very
seldom in comparison with other medicines. I can
practically say that it is very rarely prescribed in
this neighbourhood, and why ? Because of its un-
observed effects. The following is an extract from
Bentley's "Botany": — "A fatal case of poisoning
by the berries has occurred at Toulouse." Why do
we not hear more of their toxicological effects, when
so many of our damp hedges are so profusely
adorned with their tempting berries? — William West,

GEOLOGY,

Territories. — We have received a copy of the
I ninth annual report of the United States Geological

4i
which is contained a copious report of the progress
of the exploration for the year 1875, written by
Dr. F. V. Ilayden. The volume is attractive,
although bulky, and is copiously illustrated by maps
and sections. A zoological appendix furnishes us with
the new discoveries concerning the wild animals and
insects of the districts surveyed ; and this part is also
abundantly illustrated with plates. The generosity
of the United States Government in supplying foreign
men of science with numerous copies of their scientific
books is in strong contrast with the niggardliness with
which our own Geological Survey publications are
dribbled out.
The Solitaire. — In the Annals and Magazine
vf Natural History, Prof. Owen gives a lengthy de-
scription of this extinct bird, based on the remains
brought home from the island of Rodriguez during
the Venus Transit expedition. The Solitaire
{Pezophaps solitaria, Strkl.) was a huge ground-dove,
about three feet long, whose wings gradually became
aborted until it could no longer fly. The absence of
any extirpating enemies (until man appeared), and
the presence of abundant food, enabled the Solitaire
to acquire its great size.
The Geologists' Association. — Besides some
well-written and profitable descriptions of several
visits made by the members of this association to
the Crag districts of Suffolk ; Grays, Essex ; Leices-
tershire ; to Caterham, Godstone, Tilburstow,
Nutfield, Hampstead, Guildford, and Derbyshire,
the last two parts of their " Proceedings " contain
papers by the Rev. J. F. Blake, on "The Restora-
tion of Extinct Animals"; "On the Geology of

and various other kinds of Weasels ; of several species
of Skunks, of the Badger, Sea-otter, Land-otter,
and allies of these animals. This compact and handy

The Huge Fossil Bird from Sheppey. — At a
recent meeting of the Geological Society of London,
Prof. Owen described some remains of a large bird
obtained by Mr. W. H. Shrubsole from the London
Clay of Sheppey, consisting of parts of fractured
humeri belonging to the right and left sides of the
same species, or perhaps individual, and including the
head of the bone, with portions of the upper and
lower parts of the shaft. The texture of the shaft.
the thinness of its bony wall, and the large size of the
cavity, recall the characters of the wing-bones of the
large Cretaceous Pterodactyles. The author indicated
the characters which led him to regard the remains
under consideration as those of a volant bird, most
nearly approaching the genera Pelecanus and Dio-
inedca ; and as the evidence derived from the cranium
of Dasornis would indicate a bird too large to be up-
borne by wings to which these bones might have be-
longed, whilst the skull of Odontopteryx is far too small
to have formed part of a bird with wings as large as
those of the Albatross,— and Lit/iomisand Pelargornis
are excluded by the characters of their remains, the
author concluded that the bones obtained by Mr.
Shrubsole furnished indications of a new genus and
species of flying birds, for which he proposed the
name of Argillornis longipennis. He regarded it as
probably a long-winged natatorial bird, most nearly
related to Diomedea, but considerably exceeding the
Albatross {D. exulans) in size.
Geological History of the Deer Family. —
At the same meeting Prof. Boyd Dawkins gave an
outline of the history of Deer during the Miocene
and Pliocene periods. He said the majority of known
antlers could be referred to two types, — an earlier or
capreoline, and a later or axidine. In the Middle
Miocene period the cervine antler consisted of a
simply forked crown. In the Upper Miocene it had
become more complex. In the Pliocene it had become
still more complex and complicated ; and in this respect
the development of antlers in time represented that
in age of the same individual. The nearest living
analogue of the Miocene Deer is, according to the
antler, the Muntjak [Styloceros), now found only in
the oriental region of Asia, along with the Tapir, which
also coexisted with Ccrvits dicranoceros in the Miocene
forests of Germany. The Pliocene Deer, again, are
generally most nearly allied to the oriental Axis and
Rusa Deer, the only exception being Ccn'us aisanus,
the antlers of which resemble those of the Roe, an
animal widely spread over Europe and Northern and
Central Asia. The alliance of these Pliocene Deer
with those now living in the Indian region is regarded
by the author as a further proof of the warm climate
of Europe in Miocene times, confirmatory of the
conclusions arrived at by Saporta from the study of
the vegetation.
The Fossil Fungus. — In the December number
of the Science-Gossip is a reprint of a paper on
a fossil fungus, in which Mr. G. W. Smith is repre-
sented as the discoverer. My knowledge of this
particular fungus induces me to dispute his claim to
its discovery. In the first place, the section from
which he has sketched the figures to illustrate his
paper came from my own cabinet. In the second
place, I read a short paper before the Scientific
42
HARD WICKE 'S S CI EN CE-GO SSI P.
Students' Association, Manchester, during the session
of 1874-5, on tms furiSus) which was identified by one
of the members of that society as Peronosporites. No
record of this discovery was made at the time,
except in the minutes of the Society. After reading
the above paper, I put a section of this fungus
(among other sections), in the hands of my friend,
Mr. Young, for his own cabinet, and he casually
showed it to Mr. Carruthers and Mr. Smith, which
resulted in Mr. Smith's paper. This is one instance
among many of the necessity of more permanent
record being made in some leading journal of the
work of our country societies. — John Butterworth,

NOTES AND QUERIES,
British Snakes. — Is there any evidence of our
English snake feeding upon birds or field-mice, or,
indeed, anything but frogs and toads ? I have kept
many snakes (Natrix torquata), and have only twice
seen them consent to swallow toads, and that was
during very hot weather, when their appetite was
excited by the high temperature of a melon-frame, in
which they were kept. Most snakes (I am now
referring only to our native species) will prefer
starving to death, according to my observation and
that of many of my friends, to partaking of any other
food than frogs, though it is said in many books that
they will eat mice and birds.- — A. R.
Venomous Reptiles of Ireland.— Can any
reader of Science-Gossip give me information re-
specting the venomous reptiles of Ireland? Having
explored the counties of Dublin and Wicklow, I was
much struck at never coming across any such reptile,
although in so many spots where one would expect
to find them — ruins, river-banks covered with thick
undergrowth, and deeply-secluded dells. Can any
reader inform me if this is the case throughout the
isle, or how to account for the lack in these parts ?
Has climate or soil anything to do with it (casting
aside, of course, the popular legend of St. Kevin
having banished them to Glendalough) ? — S. E.
Bennett, St. Hildred's.
Pertinacity of the Hawk. — On the'soth of
September last I was staying with the family of
Colonel C, and, while they were at church, a
hawk flew into Mrs. C.'s bedroom, attracted by her
bulfinch and her linnet, each sunning itself in a
separate cage. How long the intruder kept these
poor birds in agonizing terror no one can precisely
state ; the maid, who first entered the room, chased
the enemy away, and informed her lady of the un-
welcome visitor. Mrs. C. rushed up-stairs to the
cages of her pets, and found them both greatly dis-
turbed : they approached her, and with eloquent eyes
and various expressive gestures, made her under-
stand how terribly they had been frightened by the
appearance of a bird of prey. Nothing could prove
this to a greater certainty than the loss of their
feathers, which lay scattered in their cages. The
bulfinch dropped nine feathers from his tail, and the
linnet seven. These feathers were carefully wrapped
up in silver paper and put into a box, as a memento of
that Sunday. The wretched culprit flew to an op-
posite tree, where he was watched by the stablemen,
till they saw him fly again into the tempting room,
evidently determined to make a good Sunday's meal
of the plump little birds, but there the villain met
with his due. Somebody disturbed him, out he flew,
and, clumsily, like a burglar who is caught in the
fact, knocked himself against the window, blooded it
all over, and disappeared, to be seen no more. The
hawk could not have got to these birds, the wires were
so close. — E. A. I J'.
Query as to Watercress. — The plant referred
to by Chateaubriand is the great water-radish (Nas-
turtium amphibiwn), a plant which increases rapidly
by stolons. Sir James E. Smith ("English Flora,"
vol. iii. p. 195) writes : "This plant is noticed by
the celebrated M. Chateaubriand in his account of
England, for its wonderful powers of increase by the
root. He observed it in the river near Beccles, where
he long resided as an emigrant, and his rather florid
description has excited wonder and curiosity in many
who daily, perhaps, pass over, without regard, several
no less interesting works of their Creator." I should
doubt whether the peculiar method of progression
described by M. Chateaubriand is the usual habit
either of this or any other plant, and I have cer-
tainly never observed it myself, though I have long
been familiar with this species of cress ; nevertheless
I have no doubt that M. Chateaubriand accurately
related what he himself saw, as it is exactly what
mio-ht very easily occur if the bottom were disturbed
by an oar or punt-pole. — F. V. P.
Caves in Somersetshire. — Can any readers of
Science-Gossip give me any information as to the
caves of Somersetshire, especially those of the
Mendip range, in Barrington Combe ? On an
elevated spot, known as Dolbury Camp, there is
a curious inclosure of fallen stones and earthworks,
in the centre of which is a' deep pit, of such a
depth that one cannot from the mouth see the
bottom. Can this have been a well for the garrison,
or an artificial shaft for mining, or even a natural
cave? Any information on this subject will be
gratefully received, as I have ineffectually tried to
gather explanation for some time past. — Somersu.'a.
A Feline Nurse.— Calling at a farm-house the
other day, I was told I was just a day too late to
see a very wonderful sight — a cat nursing some
little chicks. It appears the cat had a family of
dead kittens a few days before, and the same
morning some five or six chicks were hatched ; as
there were others to come out, the lady of the
house took the just hatched chicks into the house till
all were hatched, and placed them before the fire
in the sitting-room, or, as we say here, the "keeping
room." Pussy, greatly to the horror of the good
lady of the house, took a great fancy to them, and
could not be kept away from them. Wishing to
see what would take place, the owner allowed her
to come near, when she began to stroke them down
with her paw in the most affectionate and tender
manner, and, after a while, lying down, gathered
them well under her. There she lay all the day ;
in the evening they were taken from her, but next
day she did the same ; but the third day, fearful of
accidents, they were taken away from her and put
under their proper mother, who had now hatched
out her whole brood. I wonder what pussy would
have done with them. — Gobbs.
Entomological and Botanical Localities. —
Can any of your correspondents tell me exactly
where the following places in Berks and Oxon
are :_Shotover Hill, Winchwood Forest, Cowley,
Combury Quarry, Sunninghill Wells, and Bagley
Wood ? I have seen it mentioned that various

insects and plants are to be found in these localities,
and shall be obliged to any one who will give me the
required information. — H. Morton.
Nesting of Missel Thrush. — Can any reader
of Science-Gossip tell me whether it is rare or
not for the Missel Thrush ( Tardus viscivorits) to
build its nest on the tops of walls ? I found a nest
in May, 1S72, on the top of a wall, — it had four eggs
in it, and the female was sitting on it ; and another
in May, 1876. — Jas. Iugleby.
Blackbird and Thrush. — About the middle of
April, hunting round the garden, I found a nest
nearly finished, which I thought belonged to a black-
bird, though I could not catch sight of the female
bird. Two days after, looking into the nest, I found
four eggs, all just like a blackbird's, except that one
egg had the deep claret markings of a thrush : the
female being still very wary, had flown away before
I could see her. Two or three days after I again
visited the nest, and found that the bird sitting was a
thrush ; she was then very tame, and, showing no
signs of fear, let me watch her, standing within a
few feet of her nest. The last week in April the
eggs were hatched. I was unable to watch her again
for about ten days, when, to my regret, I found
that only one young bird remained ; the old bird was
then very restless, flying round and round her nest,
but never going more than ten yards from it, and
uttering incessantly a single low plaintive note. I
had then ample opportunity of watching her, aud can
state with certainty that it was a song-thrush ( Tardus
mitsicus). As soon as the young bird could fly at
all, both the mother and her offspring disappeared.
The blackbird was not nearly so assiduous in the
welfare of the young one as its mate, and I cannot
see why it should mate with a thrush when there
are plenty of blackbirds all round us. — G. T. B.
Blackbird or Thrush. — In the November num-
ber of Science-Gossip I saw a notice, by "G. T. B.,"
of Blackbird and Thrush. I have taken, at several
places, nests built like a blackbird's, but at the top of
a high fir generally (while blackbirds build near the
ground), containing eggs like a thrush's, but instead of
black spots, a few pale reddish ones. The nests were
lined with hay, not mud, as a thrush's, surrounded
outside with coarse pieces of stick and bits of fir or
grass. I have never seen the old birds, but I have
named them in my cabinet as produced by the mat-
ing of a blackbird and thrush. — S. S. B., Bradford
Abbas.
Birds' Eggs. — In your number for September last
a correspondent gives a few reasons for " birdnesting,"
which I think are open to the following objections.
To take them in order : — 1. Is it necessary that, to
obtain a knowledge of the situation and materials of
a bird's nest, the eggs need be taken ? Would not a
note, made on the spot, of the nest, its contents,
position, &c, without disturbing the eggs, be more
to the point ? 2. With respect to the many people
who take their only knowledge of ornithology from
the robbing of nests, I may venture to assert that, as
far as my knowledge goes, three out of four such
collectors take little or no interest in the birds them-
selves ; in some cases not even in the nest, the eggs
being all they look or care for. And of how much
value to science is the knowledge they thus acquire ?
3. There is certainly a great difference between taking
the eggs of domestic poultry and those of wild birds,
for in the former, domestication seems to have almost
eradicated their natural feelings (though even in them
there is some trace left, as is shown by their some-
times concealing their eggs as much as possible,
laying in out-of-the-way holes and comers), but thai
pain is thus given to wild birds, there can be no
doubt, after one has heard the painful twitter of the
parent-bird whose nest is disturbed. 4. That the
taking of their eggs is necessary to keep the com-
moner species within bounds, I fail to see. In the
first place, if there were any fear of their becoming too
numerous, why should an Act of Parliament have
been passed to check this "practice"? On the
other hand, is there not a fear of causing the rarer
species to become extinct, for it is on them that the
brunt of this "practice " falls ? How many are there,
even of those who call themselves collectors, or
oologists, who only take what rare eggs they really
require for their own cabinets? How many resist the
temptation to take all the very rare ones they find,
when they are so easily exchanged, or when a friend
would ■ be so pleased to accept them ? Of course
there are some who do, but I am afraid they are
sadly outnumbered by those who do not, as reference
to your Exchange column any month will show. But
those of the commoner kinds are neither saleable nor
exchangeable, and therefore remain comparatively
unmolested, except by the veritable nest-robber ; and
the rarer a bird becomes, the more are its eggs sought
after. Another of your correspondents reminds Mr.
Van Dyck that there is a law which prevents the
shooting of many birds during the time of their stay
with us. May I be allowed to remind him that there
is also another, to prevent the robbing of their nests ?
As to the "fond remembrances of bygone days" on
which he lays such stress, could not they be brought
to the mind just as vividly by looking through the
note-book, the companion of such rambles (he
accuses Mr. Van Dyck of a crib : may I ask him if he
has not read the paper on " Birds' Egg> " in " Notes
On Collecting and Preserving Natural History
Objects"?), and would not the pleasure of searching
out the nest be rather heightened than otherwise by
leaving the eggs ; for he is hard-hearted indeed in
whom the plaintive notes of the mother-bird raise no
touch of feeling akin to remorse ? Then we are told
that alter a "few years' " earnest collecting (it would
be interesting to know how many eggs are usually
destroyed in a few such years) most "collectors"
are able to give "not only the name of the bird,"
but an account of its habits, &c, with a "number
of interesting facts " ; but, as before mentioned, I
fail to see that it is at all necessary to rob the nest
of its eggs to obtain a knowledge of these "interesting
facts, " and if it were, to use a French expression, is
" the game worth the candle" ? In short, I do not
see that in ninety cases out of a hundred any object
is gained by breaking the laws of the land in this
particular, and cordially agree with the Editor in
wishing that all Natural History societies would
follow the good example set by the Woolhope Club.

Singular Affection of a Hen. — We had a
hen, of the barndoor or common fowl breed, say
about two years old, which we purchased, with
another from the same brood, from a farmer in this
neighbourhood some months ago. It was observed
that the hen's eyesight was dim when we first had
her, but after a few weeks the sight seemed to leave
her altogether, and of course total blindness followed.
The fowl was fed by placing her food immediately
under or close to her, and she picked up sufficient to
sustain life. The other fowls seemed to take excep-
tion at the blind hen's company, and each one, with
one exception, constantly attacked her. The curious
part of the thing was, that the sister of the blind
44
HARDWICKE'S SCIENCE-GOSSIP.
hen (previously mentioned) had chickens, and as soon
as she returned at night with her young brood (four), the
blind hen was called by the sister, and shared the pro-
tection with the little chicks, i.e. under the wing of
their mother. This continued for two or three weeks,
or until some ten days ago, when a carrion crow,
while making a predatory visit to the precincts of the
farm, observed the helpless condition of our blind
pet, and made an attack upon her, and before any
assistance could be rendered, killed and devoured
nearly the whole of the body. We, as you may
imagine, were full of sorrow for our loss. — P.
Donaldson, Goytrey, Monmouthshire.
"Fairy-flax." — In the September number of
Science-Gossip, No. 153, p. 194, Mr. Robert Hol-
land speaks of the amazing undergrowth of fairy-flax.
What plant is known under this name ? — E. L. R.
Predatory Slug.— This may have been Testacella
haliotoidea, a species known to live on earthworms ;
but usually subterranean in its habits. It may easily
be distinguished from the common slugs by the
following characters : the body increases in size like
that of a leech, from the head to the posterior end,
which terminates abruptly ; and bears a small external
shell ; it is very tough, and of a yellow-grey colour,
with grooved lines along the side of the body. The
common slugs, Limax and Avion, are, however, not
only carnivorous, but cannibals. After slaughtering
one of these garden pests, I have often found in the
evening two or three more feasting on the body of
their late comrade. Slugs and snails, as Mr. Slater
remarks, seem to be unaffected by vegetable poisons ;
indeed, the poisonous Solanacece, as Atropa Bella-
donna, seem specially attractive to them. This,
however, is less remarkable when we remember that
the rabbit, an animal much higher in the scale of life
than the snail, can eat any quantity of Belladonna
with impunity. — H. F. Parsons.
Is THE LEMMING rOUNI) IN ENGLAND ? — Is it not
very likely that the holes referred to, under this
heading in Science-Gossip, No. 152, p. 189, were
made by the common Shrew (Sorex araneus, Bell),
which it is well known makes large superficial
burrows in the earth ? The fact of its being on such
high ground is probably accounted for by the increase
of its great enemy, man, in the valleys below. The
size of their burrows would be about an inch in
diameter. — S. T.
Fructification of Sycamore (No. 155, p. 257).
— Mr. W. E. Green has, I think, scarcely appreciated
my difficulty in accounting for the increased number
of winged seeds in so many sycamore fruits. With us
in the north, although sycamores, hollies, nuts, and
some few other trees and shrubs have produced large
quantities of fruit, it has decidedly been an unfruitful
year. We have had no apples, pears, or plums, and
very few cherries ; no acorns, very few ash-keys, and
scarcely any haws ; therefore, I do not think the
phenomenon can be accounted for by supposing that
the season has been a particularly fruitful one, which
really means that the weather was suitable, or the
insects numerous enough during flower-time for the
fertilization of existing germs, or sunny enough for
the full and perfect development of fertilized germs.
If sycamore flowers usually contained several pistils,
one only, as in the Nut, coming to maturity, or even
the rudiments of several pistils, one could readily
understand that congenial weather might cause those
already existing, though rudimentary organs, to be
developed and to reach maturity ; but this is not the
case. The flower of the sycamore does not contain,
under ordinary circumstances, even the rudiments of
several pistils. No doubt, as Mr. Green suggests, an
unusually mild winter might cause great changes in
the growth of plants, but the tendency of a mild win-
ter is to produce rather a scanty crop, partly by the
blossom opening too soon, and partly by the time of
rest for the tree not being sufficiently prolonged ; and
I suspect the cause is more remote. The weather of
the present year could hardly have caused the forma-
tion of new organs ; the mildness of last winter may
have had some peculiar effect, but it is perhaps more
probable, if weather has had anything to do with it,
that there was some specially congenial weather dur-
i ing the summer or autumn of 1876 which induced
such a complete ripening of the wood that it caused
the sycamore-trees to start with unusual vigour in the
spring of this year, and that organs were thereby pro-
I duced which, had the trees been somewhat less
vigorous, would have been entirely suppressed. —
Robert Holland, Norton Hill, Runcorn.
The Tyrian Dye. — Your correspondent " B."
(see No. 155, p. 260) is evidently unaware that this
celebrated dye was of a crimson hue, or he would not
1 have imagined that it might have been extracted from
Leptoclinium punctatum, "because when put into
I water, it (Z. pnncta/itm) stained the water of a blue
colour." The word purpureas, whence the English
purple, signifies "bright red," as Digitalis purpurea,
j the Foxglove. The present corrupt use of the word
; purple to signify a shade of blue is quite recent. Has
" B." never read Izaak Walton's lines on fishing, in
. which he mentions the common perch, with its " fins
of Tyrian dye"?— W. R. Tate, Blandford, Dorset.
A Curiosity .—I have in my possession a Hindoo
or Burmese sword-handle made from an elephant's
tusk, on which, after the Eastern fashion, many quaint
and curious figures are carved: men with grotesque
and hideous faces disfigured with elephants' trunks,
crocodiles' mouths, monkeys' heads, and the like.
Among these forms, but separated from the rest, is
carved a tiger or bear, I am not sure which, but
think the latter : in its mouth it holds a fish. Now,
I should very much like to ascertain if this has been
carved among its fellow-anomalies as a prodigy that
has been said to have existed, but which the executor,
desiring to ridicule, placed among his monstrosities.
South American travellers of good repute tell tales
of the common jaguar (Leopardus Onca) hanging over
the banks of streams, and catching the unwary fish
that chance to pass by. Is it on record that any
member of the Felidre or Isabella; of the old world
ever performed the same feat ? — Daccart Aikone.
Sudden Change in Colour of the Human
Hair. — " Is it possible for a person's hair to turn

now on record, that there ought to be no longer any
doubt upon the subject. In the late Arctic expedition
nearly every man's hair became greyer, and in some
cases white, but assumed its natural colour when the
men returned to lower latitudes. In many cases the
human hair is said to have turned grey from grief,
extreme care, or sudden fright. My experience is
very small, but nevertheless may be interesting to
some of the readers of Science-Gossip. During an
outward passage to Australia, the ship I was in
suffered greatly in the British Channel ; twice we
were nearly wrecked, having lost three anchors and
two cables. The pilot who had charge was con-
stantly on watch, only snatching a few minutes' sleep
here and there, as opportunity afforded. On the
whole, he had a very anxious time indeed, and when
he eventually left the ship off the Isle of Wight he

certainly looked twenty years older. I thought his
hair had decidedly turned greyer : this may, however,
have been only imagination, and therefore ought rather
to be considered as an impression than actual fact.
Within the last few months a fresh case of the possi-
bility of the colour of hair changing has come under
my notice. An old gentleman, aged eighty-nine,
residing in my immediate neighbourhood, lately died.
For many years his hair had been perfectly white,
but a few days before his death some of his hair
became black, giving the appearance of his having
dark brown or black hair. Here it is interesting to
note that in his younger days his hair was light.
After the death of this gentleman the tips of the hair
for about an inch assumed the original colour,
becoming white again. Has a similar case fallen
under the notice of any of your readers ? I have heard
of another instance, where after death the hair turned
from white to black. Dogs seem to be affected with
regard to their hair in like manner as human beings.
I lately read of a case where a black Newfoundland
dog became grey in a few weeks ; and the writer
declares that the only cause for this sudden change
was grief. — C. P. Ogilvic.
Mistletoe, Apple, and Pear. — Does not the
fact mentioned by Mr. C. H. Westley, that mistletoe
does not grow commonly, if at all, on the pear, open
up some interesting questions ? I believe I am correct
in saying that, though the apple and the pear can
each of them be grafted on a variety of stocks,
amongst others on some but remotely related to them,
neither can be grafted on the other. The growth of
the mistletoe is a kind of natural grafting, and occurs
on trees belonging to several widely different orders ;
yet it seems to be confined to one of these two allied
species. May there not be some underlying physio-
logical identity between the various possible stocks,
some physiological difference between apple and
pear ? Has any one ever attempted to graft apple or
soecies ther on mistletoe? Will mistletoe grow on
all stocks used for apples, or on any used for pears ?
— G. S. Bo i tiger.
Mistletoe. — Bentley mentions Viscum album as
parasitic on thorns and willows ? Can your readers
tell me whether it is commonly found on these ? also
whether Primus spinosa is the plant meant by
thorns ?— J. J. W. S.
Watercresses. — The following extract may per-
haps be of interest to some of your readers. At the
meeting of the Royal Horticultural Society on
Tuesday, Mr. Shirley Hibberd, of Stoke Newington,
presented a dozen pans of watercresses, grown in the
manner he has practised for some years past. One
of the advantages of this system is, that the plants
are under complete control to be placed in the sun or
the shade, or during winter in heated plant-houses,
and can at all times be supplied with pure water, and
thus be preserved from contamination by the pollu-
tions common to rivers, and even to watercress-beds.
The pans in which they are grown measure from
1 5 inches to 20 inches across, and from 6 inches to
9 inches deep. They are filled with rich loamy
soil, intermixed with lumps of chalk or old mortar,
and then very small cuttings are inserted. These
soon become strong plants, and in from fifteen to
twenty days may be gathered from, the cresses being
tender and delicate in flavour, and of the most beau-
tiful appearance. The twelve plants shown have
been regularlvcut for the table for a period of six weeks,
and their fresh and robust appearance indicated that
gatherings might be had from them for another six
weeks without their being exhausted. The sorts shown
were die Erfurt sweet green cress, the Springhead
brown cress, and the Stoke Newington purple cress.
The adjudicators signified their approval of this mode
of cultivation by the award of a medal to Mr. Hibberd.

Query respecting Sea Anemones. — Will a
correspondent kindly give a little information respect-
ing Sea Anemones : should they be fed, and if so,
how often, and about in what quantity ? — W. T. H. C.
Trome.
Swans and Rats. — Some time since I noticed
some rats had taken possession of a hollow tree grow-
ing by the side of my mill dam, and not wishing to
retain them there as tenants, I suggested to one of
my servants the propriety of serving them with
"notice to quit," and to this end I enlisted the ser-
vices of a ferret. Very soon two or three of the family
leaped into the water. A pair of swans were close
by watching our movements, and no sooner did the
rats attempt to swim across the dam, than the swans
at once gave chase to the enemy ; more than once they
seized the rats and threw them above the water, and as
often as they raised their heads, the swans, regardless
of the presence of spectators, pursued their enemy to
their bitter end, and by frequently pecking at them
eventually succeeded in drowning them, as was proved
by the dead bodies floating down to the mill ruck a
few minutes after the battle. — R. Cooke, G Ian ford-
Mill, Norfolk.
Spectral Phenomena. — Two curious phenomena
have lately come to my knowledge in conversation
with friends who were eye-witnesses of them.
Perhaps some of your readers may be interested
enough to endeavour to throw some light upon them.
A gentleman was parting with a friend on Hampstead
Heath, one night about eight years ago, the moon
and stars shining, when they both observed what
appeared like three bright bars stretching across the
sky about midway between the zenith and horizon
towards the west, and apparently also twenty or thirty
yards in length, and remaining so for over half an
hour. A lady walking along the Euston road when
the sun was shining brightly, saw in the air before her
a gigantic semaphore. Upon reaching one of the
stations of the Metropolitan Railway, a real sema-
phore was noticed to correspond in position with the
spectre. — A'. II. A. B.
The Lunar Bow. — I observed this remarkable
phenomenon on November 22nd under very favour-
able circumstances. At about 8.25 p.m. the moon
was shining very brightly, and on looking towards
the western sky, I perceived a faintly-coloured bow
spanning the heavens and extending some distance
across the distant landscape. The colours were pale
and indistinct, but the general form of the bow was
very definitely marked. — George Clinch, West Wick-
ham, Kent.
Lapwing and Sparrow-hawk. — I am not much
surprised at the communication of J. C. Stephens,
No. 155, p. 262, in which he states that he " observed
a lapwing or peewit pursuing a sparrow-hawk."
I believe that, under certain circumstances, that bird
will attack, or at least chase and attempt to frighten,
any bird whatever that approaches the ground where
it has taken up its abode. As a proof of this I will
mention what came under my own observation during
the past spring. In a field of about twelve acres
in extent adjoining my residence, two lapwings took
up their abode. There are some rookeries at a short
distance from this, and on several occasions the
colonies came into this and the adjoining fields to
46
HARD WICKE 'S S CIENCE - G O SSIP.
forage. For some time the lapwings paid little
attention to the crows, but ultimately the female
commenced to hatch her eggs, and then a real warfare
began with the male. No sooner did the crows,
generally two or three hundred, alight in the field
where the female was sitting, than the male com-
menced a most determined attack on them. It darted
towards them with the rapidity and vigour of a hawk,
but evidently with the sole intention of banishing
th cm from the field, as I could never notice that it
came actually in contact with them, but always so
near as to render them uncomfortable. Those who
have observed a lapwing under these conditions
will be aware of the peculiarly loud noise that it has
the power of producing with its wings, and this, no
doubt, has its effect upon the birds that approach its
domain. This was the case in the present instance.
Not a moment's quietude was allowed the crows until
the whole colony was banished from the field, and they
were obliged to betake themselves to the neighbouring
grounds, where they could follow their occupation in
peace. Not more than a few minutes elapsed until
the lapwing had cleared the field of the intruders.
T witnessed cases of this kind repeatedly, and always
with the same effect. This faithful sentinel of its
mate would allow no bird whatever to enter this field
without attempting to banish it. These attacks of
the lapwing were not confined to birds alone, but also
to human beings. If any person happened to pass
through this field, and more especially when near the
nest of the female, the male immediately darted past
him on all sides, and so contiguous that it might
almost be touched, making the peculiarly loud noise
with its wings. Thus it continued without inter-
mission until the intruder had left the field. On one
occasion I was greatly amused with a crow that it
took prisoner. The crow alighted in the field near a
tree, but the moment it did so the lapwing commenced
its usual attack by darting close past it (on no occa-
sion did I see it come fairly in contact with the
intruder), and the crow to avoid it took refuge in the
tree. The lapwing then soared away for a short
distance, but never out of sight of the crow, and the
latter, no doubt thinking that its enemy had dis-
appeared, left the tree and again began to forage in
the field. But this was only momentary. The lap-
wing was quite aware of the fact, and down again it
pounced on the crow, which, as before, took shelter
in the tree. This state of things continued more than
a dozen times, until at last the crow, finding that
neither peace nor profit could be obtained there, con-
trived to steal from the tree, and took its departure to
some other locality, where it might forage in peace
and quietness. The courageous and faithful guardian,
however, at last came to an untimely end. I did not
witness this myself, but was told by a game-watcher
who did, and therefore cannot say whether the hawk
which killed it did so without provocation, or that the
latter had been annoyed by the usual attack of the
lapwing to banish it from the field. However, the
lapwing was struck to the ground by the hawk, and
the game- watcher, thinking that he might be able to
save its life, went to its rescue with all speed, but on
reaching it found that the hawk had torn its head off.
Since that time I have never seen the female, nor any
ofitsyoung — if it succeeded in hatching them, — and the
crows may now be seen daily foraging in the field
without interruption. — Dipton Burn.
The Betularia and its Varieties. — In the
month of June, 1874, I was proceeding on the out-
side of an omnibus from Middleton to Manchester
in company with a brother entomologist, when I
thought I observed a large specimen of the Betularia
in a plantation in the neighbourhood of Heaton
Park, on the left-hand side of the high road. The
driver of the 'bus, noting my anxiety to capture the
specimen, very kindly promised to proceed slowly for
a short distance, so as to give me an opportunity of
seeing whether my impressions were right or not with
regard to what I had seen. I soon reached the plan-
tation, near the entrance to which, to my great joy and
surprise, I found a large female Betularia of the buff
variety on a tree, in conjunction with a black male.
I picked them off the tree and returned to the 'bus,
several of the passengers being astonished when I
told them the value of my prize. Not being prepared
with a box at the time, I allowed my captures to
creep on my clothes, but after we had gone some
distance I set the black one free, to the evident sur-
prise of the passengers, who seemed to think that the
more valuable of the two. However, on arriving at
Cheetham Hill, my entomological friend procured a
large-sized pill-box, and into this I placed the buft
specimen. We proceeded to Belle-Vue Gardens, to
spend the afternoon, though I will confess that the
pleasure I experienced there received additional zest
from the discovery and capture I had made during
the afternoon. On arriving home I was sorry to find
the specimen in a somewhat sorry condition, the box
in which I had confined it having been rather too
small. Fortunately I succeeded in restoring it, and
I afterwards reared about 120 specimens, but,
singular to say, and to my great disappointment,
the buff variety did not make its appearance. At
this time a friend of mine had some of the black
variety, and he was kind enough to give me a few ; so
I crossed them, but with the same result. Still I
had faith that they must have some of their parent's
buff qualities in them, and I made another attempt
to breed them. The result, I am glad to say, was
very gratifying indeed. On the 4th of December last
I placed about fifty of the pupa? in a box ; for, being
very eager to see the buff variety come forth, I
resolved to try what artificial means would do.
Impelled by curiosity, I, on the 4th of January this
year, took a peep into the box, when, to my great
delight, I found that one of the buff variety had
emerged from the pupa. I followed up my success,
and have succeeded in obtaining about one buff one
out of twenty of the whole brood, some of them being
all buff, and others very variable, both in their colour
and markings. The foregoing information, therefore,
makes me feel confident of having established two
distinct varieties of Betularia from a domestic point
of view, and possibly what I have stated may be of
value to entomology, and to those who love the
science. — Thomas Lomas.
A Fight with an Eagle. — The Dagbladet, a
Danish newspaper, for July 10th, 1S76, gives the
following account of a rare incident which occurred
on the previous Wednesday evening upon Rovling
Heath, in the district of Aalborg, Jutland. Two
girls, eight and twelve years of age, having been sent
by their parents to fetch home the cows from the
heath, were attacked, while returning, by a very
large eagle, which made several attempts to swoop
down, but was deterred by the elder girl swinging a
tethering mallet over her bead till she could procure
some stones ; these she hurled against her powerful
antagonist, and was at last so fortunate as to strike it
with such effect that it fell dead. It measured from
tip to tip of its extended wings, six feet eight inches
(3} alen), and weighed about ten pounds (9 pund).
Its largest claws were from an inch and a half to two
inches long ; its colour was intermingled grey and
white. — J. Wager.

Colias Edusa and its Varieties. — At the time
my few notes on this interesting butterfly were
written, which appeared in Science-Gossip, No.
156, p. 280, I considered myself fortunate in secur-
ing two of the white varieties, having collected
thirteen or fourteen years, and being obliged till this
year to put up with one tattered English and a foreign
representative. Since then, however, my brother
and I have captured forty-five Helice, forty of which
were taken in one field close to this town. The
specimens exhibit much variety in colour, some being
a rich cream and primrose, others a greenish white ;
in the size of the marginal spots there is also great
difference ; in some they are reduced to a minimum.
— Joseph Anderson, Junior, Chichester.
Destroying Mites. — Your correspondent,
"A. F." will, I think, find no difficulty in ridding
his collection of mites, if he will adopt the following
plan, which I have never known to fail. It is simply
to dip a camel-hair brush into benzine, and let the
fluid fall upon the insect drop by drop until it is
completely saturated ; the little heaps of dust which
usually betokens the presence of mites underneath
the specimens can be wiped up with the brush. On
account of the extremely volatile nature of benzine, it
is not of much use as a preventive for this purpose ;
it is better to employ plenty of camphor, or cotton
wool soaked with a solution of carbolic acid. With
even ordinary care mites need never be permitted to
do any serious mischief, and no better piece of advice
for their prevention can be given than that by
Dr. Knaggs, to put into quarantine every insect we
receive. — Joseph Anderson, Junior, Chichester.
Destroying Mites. — Many years since I left two
cabinets of lepidoptera in the country for some twelve
months, and on bringing them home found the bodies
■of many of the specimens eaten, and the mites travel-
ling over the drawers in large numbers. I made a
saturated solution of camphor in rectified spirit of
wine, poured about a teaspoonful in one corner of
each drawer, and by tilting, caused the liquid to flow
round the angles ; I then closed the cabinets, and on
opening them a few days after found all life extinct.
If "A. F." has not a compartment in each drawer for
camphor, he should procure some muslin bags about two
inches by one inch and a quarter, put a lump of cam-
phor in each, and fix one in a corner of every drawer by
a pin at both ends, renewing the camphor as often as
it evaporates. By this means he may preserve his
collection from injury by mites for any period. —

The Sun and the Earth. — I have the following
figures before me of the distance between us and the
sun. Taking Guyot's mean diameter of the earth,
giving a radius of 3,938 miles —
Laplace gives a distance of miles = 92, 636,990
The Quarterly Review, July, 1875,
note, p. 209 =91,000,000
The Academy, 20th October, 1877,
P- 389 =93,000,000
The Mail, 19th December, 1877,
in a letter from Mr. Proctor
{ Tupman =93,321,000
( Newcomb =92,393,000
Mr. Proctor suggests that this measure is un-
trustworthy, as long as we get warmth and light, the
actual distance of the sun is of little consequence ;
but what are the precise sciences to do ? Newcomb
and Laplace are as near the mark as we can hope for ;
but how is it that the precise sciences reach their
conclusion as to the size of this world from the
Nebular hypothesis of Laplace, without adopting his
measure of distance between the earth and the sun ?
I find the figures for Laplace in his translation by
J. Pond, p. 24, 1809. Will some one kindly tell us
which distance is right ? — //. P. M.
Reasoning Power of Dogs. — Having witnessed
the following occurrence some years ago, I could not
help being struck with the great reasoning powers
displayed by a dog. I lived in the town of N ,
and the back of our terrace had small gardens, sepa-
rated from each other by a short fence. One windy
morning the clothes were drying on the line, and the
dog (a fine retriever) was sporting itself on the grass,
when a sudden gust blew the "things" on the
ground ; the dog at once ran into the house, and by
sundry barks and pulls at her dress, induced the girl
to go into the garden, where she discovered the cause
of the dog's uneasiness. The next day being the
"week's wash" of our neighbour, the clothes were
airing in the garden, when our dog rushed into
the house, and presently brought out the servant,
who found that the prop had given way, and the
" wash " was all on the ground. — J. D.
Superstitious Dislike to the Wren {Troglo-
dytes Europa-us). — This little bird, though generally
a favourite, is in some rural districts regarded by the
uneducated with the bitterest aversion, while its rela-
tive, the Redbreast, is considered sacred from all
molestation. So deeply seated is this hatred to the
Wren, that its nest is often ruthlessly torn away,
and both nest and its contents trampled under foot.
The only explanation which these good folks will
vouchsafe, is that the " wran" is the devil's bird,
and should therefore get no quarter. This strange
superstition has, I believe, had its origin in one of
the many myths which have been handed down from
generation to generation, and received as truth be-
yond question. The legendary account of how the
Robin got her red-breast is widely spread, both in
Ireland and England, and no one in this country will
molest the "poor robin," because his name is asso-
ciated with our Lord ; but the Wren has the mis-
fortune of being associated with the sacred history in
an unfavourable light : hence the odium which hangs
around him. In the south of Ireland it appears this
unkindly feeling does not exist, which is shown by a
curious practice which existed at no veiy distant date
in Cork. On St. Stephen's day a number of young
men, in holiday dress, paraded the city, carrying a
furze-bush, in which a wren was secured. As they
stopped before the house, one of their number recited
the following lines —
" The wren, the wren, the king of all birds,
Was caught St. Stephen's day in the furze ;
Although he's little, his family's great,
Then pray, kind gentle folks, give him a trate."
It is to be hoped that this cruel and unmeaning
dislike to a little bird of which poets have so sweetly
sung, and naturalists so interestingly written, may
; ere long be swept away by advancing education. —
' H. Allingham, Ballyshannon.
Harebell ( Campanula rotundifolia). — The English
^ name, we are told, was bestowed upon it because it
' grows in the dry and hilly pastures frequented by the
hare, but we would suggest, at least, an alternative
derivation — or rather the plant itself suggests it — as
to whether it may not have originally been named
hair bell from the extremely light and delicate stems
from which the blossoms hang. Another plant,
equally light and delicate, is named the maiden-hair.
I have extracted the above from p. 78, part 10, of
" Familiar Wild Flowers," to which I refer Mr. Tate
for an interesting article on the plant. — T.

NOTICES TO CORRESPONDENTS.
To Correspondents and Exchangers. — As we now
publish Science-Gossip at least a week earlier than hereto-
fore, we cannot possibly insert in the following number any
communications which reach us later than the 9th of the
previous month.
Fresh Chara. — A correspondent asks our good offices to
obtain for him "a little fresh Chara." Will our botanical
friends, who can obtain it, send us a small supply ?
W. Patrick. — You can purchase Anodotis of R. Damon,
F.G.S., Weymouth.
A. F. Fischer. — You cannot do better than preserve the
chrysalis in the earth of a flower-pot. Put the latter out of
doors. It will soon cease " wriggling." Out of doors is their
natural condition of hybernation.
W. H. Legge.— The caterpillar of which you sent us a
coloured drawing, is that of the well-known Pale Tussock-moth.
The caterpillar goes by the name of the " Hop-dog" (prgyia
jntdibvnda).
Y.. M. (baddleworth).- — The specimens sent us from the turf-
pits are flint chips, and seem to us to be the result of human
handiwork. This appears all the more probable from the fact
that flint is a very rare mineral, even in the drift beds, in
your district. Can you send us some larger specimens for
inspection ?
W. H. S. (Colchester). — We shall feel obliged if you will
send us some of the insects which demolish the " black beetles,"
as we cannot identify them from your description.
W. S. Wakefield. — The plant sent us is Veronica Hen-
dersonii.
F. Coleman. — We have heard of no other instance of non-
fulfilment except your own.
J. A. Sandkokd (Ohio). — Accept our thanks for specimens of
AJ>ocy>ium androsamiifolnim,
C. W. H. — There is no fear whatever of the ants doing your
Deodaras any harm.
Colonel M. — You had best have Science-Gossip sent to
you direct from the publishers. The small crystals are car-
bonate of lime,
F. R. B. — We cannot, of course, tell you the name of the
species of mussel without seeing specimens. But there is no
doubt that the deposit in question is a post-glacial one, of the
same age as our raised beeches.
F. Q. — You had best consult Whitaker's "Geology of the
London Basin," published by Her Majesty's Stationery Office,
for details of and references to the various sections of the
Woolwich beds exhibited in the neighbourhood of London.
S. C. M. — Sach's " Botany," translated and edited by A. W.
Bennett and Professor Dyer, and published by the Clarendon
Press, gives the best account of the laws of vegetable growth
and development.
A. M. (Wandsworth). — The crustacean, of which you sent us
a drawing is Idotca tricuspidata.
J. Ransom.— We have no doubt that Mr. Bartlett, the
Superintendent of the Zoological Gardens, would give you all
the necessary information respecting the management of
Marmosets.
T. C. M.— -We have referred to the MS. of your " Exchange "
in the January number, and find that we printed it exactly as
you wrote it !
R. T. Andrews. — The "glass-like substance" you sent us
is Selenite, or crystallized sulphate of lime ; very likely from
the London Clay formation.
J. Cunnack. — Your written description of the Hawk answers
best to that of the common Buzzard (Puteo vulgaris).
W. K. and Others. — Your specimens have been forwarded
to competent authorities to be named, and their names will
appear in these columns as soon as we have received them.
E. R. F. — Potton, in Bedfordshire, is situated on the Lower
Greensand formation, and the fossils you mention are, no
doubt, from that deposit.
W. B. wishes for the address of the South London Ento-
mological Society, as it has removed from its old quarters. We
shall always be glad to chronicle such changes of removal.
C. Harris. — Many thanks for the specimens, which are very
interesting. But we cannot undertake to name zoophytes from
the Cape of Good Hope, or any other place where the fauna has
not been scientifically worked and described.

THE FLORA OF NATAL
By J. M. WOOD.
S possibly some of your
readers may feel inte-
rested in a few notes
on the flora of this
part of the world, I
will, with your per-
mission, enumerate a
few of the native
plants at present grow-
ing in my garden. I
reside about twelve
miles from the sea, and though my garden is
neither extensive nor particularly well kept, still
I have taken pleasure in adding to it some of
our beautiful native plants, a number of which
were already growing in it when I came to reside
here, having been planted by a former occupant.
The first plant which attracts the eye at this season
is Gieya Suthcrlandi, a shrub or small tree, now
covered with its beautiful scarlet flowers, though
the leaves have hardly yet made their appearance;
it is a sapindaceous plant, though its true position
appears to be doubtful, and is a native of the higher
districts of the colony, in the Drakensberg, a range
of mountains on the border of the colony. I am told
that its spikes of flowers are sometimes a foot or more
in length. Here it is usually called the "Natal Bottle
Brush," but it is rarely seen in cultivation, as, on the
coast, at least, it does not succeed well. Close beside
it is Crinum Capense, usually called in the colony the
"Natal Lily," and everywhere found in profusion, from
the coast to far inland ; and in the ,spring and early
summer producing its corymb of pink and white bell-
shaped flowers. Near this plant is an Arum, of the
genus Richardia (known here as the "Lily of the
Nile ") ; it is now out of flower, but in the season
flowering freely without the slightest care or attention.
On the opposite side of the walk is another Arum of
the same genus, whose leaves are spotted with white,
like a Caladium, and which has a primrose or yellow
spathe, and which is in this district quite plentiful.
Beyond this plant, and scrambling about amongst the
No. 159.
adjacent shrubs, is a species of Mesembryanthtmum,
with small but richly-coloured deep magenta flowers ;
and near it another species with larger white flowers,
and which is in some places near here quite common.
In the middle of a small grass-plot in front of the
house are two plants of Encephalartus, a cycadaccous
plant, which sometimes has a caudex 10 feet or more
high ; one of these plants, though its stem is only
about iS inches high, has produced three large cones
in the centre of the crown of leaves or fronds, some-
thing like overgrown pine-apples. It is, I think, a
male plant, though the scales are not yet sufficiently
separated to decide with certainty ; during the five
years that I have observed the growth of these plants,
they do not seem to have increased much in height,
but as they only put forth one crown of leaves in each
season, this is not to be wondered at. The largest
plant has upon it at the present time four sets of
leaves, the lowest whorl of which are now nearly five
years old, and rapidly decaying ; but when the spring
has fairly set in it will unfold another complete
crown of leaves, and thus the trunk gradually increases
in height year by year. These plants were brought
from Noodsberg, twenty miles from here, where they
grow on the sides of precipitous rocks and under
slight shade, at an elevation of 3,000 feet or more
above the sea-level. We have a species of cycad
growing in similar situations near here, but which
does not, even in old age, develop a trunk ; its root
is napiform, and, when dug out, as much as a man
can carry with comfort ; it bears pinnate leaves
6 feet or more long. Near this latter plant is Stan-
geria paradoxa, also a cycadaceous plant, found, I
believe, only in Natal, and named in honour of the
late Dr. Stanger, Surveyor-General. It is a very
common plant in this neighbourhood, both in the
open grass and in bush, and has the fruit of a conifer
with the venation of a fern. On one side of the
grass-plot is a fence formed of an apocynaceous plant
of the genus Carissa, called here the ' ' Amatungulu, "
and which bears a fruit which is much esteemed. It
has pretty white star-like flowers, and plum-shaped
5°

scarlet fruit, but its double or forked thorns make it a
rather unpleasant plant to come violently into contact
with. The fruit, when unripe, is rather astringent,
and full of a white milky juice ; and it is a standing
joke here, that J. C. Byrne, the emigration-agent in
the earlier days of the colony, when speaking in
England of the natural products of the place to which
he wished to attract the emigrants, said that in Natal
the strawberries and the cream grew upon the same
plant. The fruit is extensively used for making jams
and jellies, a large quantity of which is, I believe,
exported. At each end of this fence, and also around
and near the house, are trees of Eucalyptus globulus,
a native of Australia, some of them 70 feet high,
though I believe only twelve years old ; and twining
round one of these gum-trees is the stem of a native
plant, Testutidinaria elephantipes, the Tortoise-plant,
or Elephant's foot, a singular-looking plant, belonging
to the family Dioscorea, or Yams. Its rhizome, which
is above ground, is hard and tesselated ; and in my
specimen the resemblance to a tortoise is sufficiently
startling. It is perennial, and sends up a slender
twining stem to the branches of the trees amongst
which it grows, while the rhizeme sends down tough
wiiy rootlets, with which it takes firm hold of the
ground. The specimen under notice was the first
which I had seen, and in climbing up some rocky
ground I placed my hand upon it, but quickly with-
drew it under the impression that it was the shell of
a tortoise. There are, I believe, two species of this
plant in the colony, but I have only met with one as
yet. We have also two species of Gardenia, G. glo-
bosa, now completely covered with its creamy bell-
tnaped flowers, and G. grandiflora, with larger,
salver-shaped flowers, which fill the garden with a
delightful perfume. Then there is that rare plant,
Mackaya bella, with its pale lilac pendulous flowers
and curiously-veined corolla. I have been informed
that this plant is only found wild in the valley of the
Tongaat, but whether this is correct or not I do not
know ; at any rate, it is not by any means common.
Then we have a croquet-lawn, formed of a running
grass which is commonly used for that purpose here ;
and at one end of it stands a row of trees which have
originally been stakes in a post and rail fence, but
which have now grown into trees, some of them fine
ones ; two belong to a species of Aralia, common
here, and much used for fencing, as the post will gene-
rally take root. Two others are fig:trees, of a species
plentiful about here, and which have now grown into
fine spreading trees, 20 to 30 feet high, with leaves
which arc thickly covered underneath with small
peltate scales or glands, the use of which I have not
been able to discover. While the leaf is fresh, they
appear, under the microscope, to be closely adpressed
to the leaf; but as the leaf dries, they curl up at the
edges, and are then easily detached, leaving a small
pit or hollow. Three more of these trees belong to
the genus Erythrina, or, as it is called here, " Kafir
j Boom," and are now covered with beautiful scarlet
! blossoms, but without a single leaf. This tree is
common in the colony, and during the winter months
its magnificently-coloured flowers make it a very
conspicuous object. We have several species in the
colony, two of which are growing here ; one is usually
called the ' ' Cork-tree, " as its bark has much the appear-
ance of rough cork ; its leaves are large and coarse,
and the wood of both species is so light, that I believe
it is sometimes used for floats in fishing. I have used
it for setting butterflies, for which purpose it answers
almost as well as cork, which is not procurable here.
And I have no doubt that it may yet be put to many
other uses, though at present it is not used, as far as
I know, for anything but fencing. I have also a
small fernery, of which I may have something to say
on another occasion, should it be acceptable to your
readers, and also about the numerous wild flowers
growing so profusely in this neighbourhood.
THE LATE ANDREW MURRAY, F.L.S.
BY the death of Mr. Andrew Murray, which
occurred on the 10th ult. at his residence in
Bedford Gardens, Kensington, entomology and
botany loses an assiduous and careful worker. Born
in Edinburgh in 1812, he paid some attention in his
youthful clays to the study of medicine. He was,
however, educated with a view to following the law
as a profession, and for a short time practised as a
Writer to the Signet. Subsequently he assisted his
relative, John Murray (Lord High Advocate), in his
desire to provide some practically useful reading for
village schools by writing a little pamphlet entitled
"The Skip-jack; or, Wire- worm and the Slug,"
which, though published without his knowledge, may
be considered as his first contribution to economic
entomology. The year preceding his removal to
London, he contributed to the " Transactions of the
Royal Society of Edinburgh " a paper relating to a
subject then under discussion, as to what extent the
unity of species in the parasite showed unity of
species in the animal preyed upon; "the pediculi
infesting the various races of man," giving minute
descriptions and considerations as to how far the
variations might be considered to amount to specific
differences.
After his removal to London in 1S60, Mr. Murray
devoted himself specially to the sciences of ento-
mology and botany. About this time he became
officially connected with the Royal Horticultural
Society, being appointed assistant-secretary. After
relinquishing this post, he continued, almost to the
moment of his death, to show a great interest in the
society, being one of the strongest supporters of, and
most frequent attendants at, the meetings of the
scientific committee.
In 1869 he formed one of a party, including Sir
HARD WICKE'S SCIENCE- G OS SIP.
5i
Joseph (then Dr.) Hooker, of representatives of
English science at the Botanical Congress at St.
Petersburg. In acknowledgment of the service
rendered on this occasion, he was presented by the
Emperor Alexander with a splendid malachite table.
During his absence from England at this time, he
paid considerable attention to the subject of Conti-
nental forestry, and every facility was given him in
his inquiries in Belgium by the Belgian Government.
In 1 87 1 he undertook the laborious task of superin-
tending much of the selection or arrangement of the
English exhibits at the Polytechnic Exhibition at
Moscow in the following year. In botanical science,
Mr. Murray's work lay principally among the
Conifene, having written a small book on the " Pines
and Firs of Japan," and contributed numerous papers
on the same group of plants to different scientific and
horticultural journals. He was secretary to the
Oregon Committee, who sent out a collector to Oregon
and California to collect Coniferse, and in 1873 he
undertook an expedition to Salt Lake and California,
partly with a scientific object, and partly with a view
to investigate the working of the silver-mines. In
the course of his mining investigations he was ex-
posed to considerable danger, minute inquiries mak-
ing him obnoxious to some of the parties concerned.
In his entomological career, the great point was
the devotion of the last ten years of his life to the
subject in its practical bearings. As a monument of
his skill and profound knowledge on this point, the
results stand in the Government collection of econo-
mic entomology at Bethnal Green. The charge of
receiving and arranging the contributions to this
collection was placed in his hands officially in 1868,
and from thenceforward he may be said to have
given himself up to the task unceasingly, down to his
latest hours ; for, during his American expedition,
he left behind him the threads by which the collec-
tion might be proceeded with in his absence.
Of the patient labour and scientific research he dis-
played in this collection it is impossible to speak too
highly. Under his guidance the life-histories of the
insects (of which knowledge was required to ascertain
their remedies) were, in some cases, worked out,
in others verified and amplified ; remedies were
ascertained and experiments initiated ; and the whole
life-history was shown at once correctly, scientifically,
and as clearly as possible to the popular eye by
illustrations of the insect in its various stages, and the
object injured, accompanied by drawings and, when
possible, facsimile models. Mr. Murray was an
accomplished draughtsman, and a large number of
the insect drawings are his own work, in all cases
clearly executed, and many, especially those of the
Coleopterre, really works of art. On this collection
he was working up to his latest days, having, we
believe, a quantity of material in progress of arrange-
ment. It is much to be regretted that his descriptive
catalogue of the collection should not have progressed
beyond the first volume devoted to the Aptera,
which was to have been followed, as we learn from
an introductory note, by a complete series. The
compilation of such handbooks is a work requiring
great knowledge of the subject, as well as familiarity
with writings of previous observers, and the head and
hand which formed the collection could best give us
the description which utilizes it for general reference.
Mr. Murray contributed valuable papers of original
observation both to home and foreign scientific
societies and serials, and amongst his larger works, his
volume on the " Distribution of Mammals " is one of
very great value, with regard to the representation of
families, both prehistoric and present, and also for
its synonymic lists and tables.
It is said that Mr. Murray's health suffered much
during his American tour, but that the immediate
cause of the unfavourable change was due to the
amount of chloroform inhaled whilst rearranging a
portion of the Doubleday collection infested with
Mites. He was not in strong health at the time, but
continued at his post from day to day, trusting that
after effects might wear away ; his general health,
however, sank from that time, and all who had the
privilege of knowing him will feel that by the death
of Andrew Murray they lost a true-hearted and loyal
friend, as well as a gifted naturalist. J. R. J.
ON SOME RECENT FORAMINIFERA FROM
THE SHETLAND ISLES.
S
By George Robert Vine, Jun.
OME time ago my father gave me a small
packet of dredgings that he had received from
Mr. Lovett, Holly Mount, Croydon. The dredgings
consisted of minute particles of broken shells,
quartz, &c, but especially of Foraminifera. These I
worked out, and the following is a list of the species
obtained.
Globigerina bulloides, D'Orb., both in the young and
mature state, were very plentiful ; Rotalia Beccarii,
Linne, Very small, but showing the character of the
genus well; Rotalia oi'bicularis , D'Orb., and varieties,
small, transparent, and perfect, common ; Planorbu-
lina [Truncatulina) lobatula, Walker and Jacob, very
common in Dog's Bay, &c, but only 8 or 9 speci-
mens here represented the genus, and all these were
not very distinct in the septa and foramen, but distinct
enough to identify the species ; Operculina ammono-
ides, Gronovius. This is a species hat can hardly te
mistaken for another, being ammonite-like (as the
name implies), with the septa distinct and double
(see fig. 31); small and middle size, rare; Pulvimdina
Micheliniana, D'Orb. (see fig. 28). This is a peculiar
species : it has three different views ; the front is raised
very much, with the septa rather wide apart ; the
bottom is flat, with two convolutions showing the
primordial, and the side view is bell-shaped; middle

size, rare. One species, resembling a Nonionina, is
rather common: it is middle size, and has all the septa,
foramen, &c, very much obliterated. Another most
beautiful form is very common : it is small, semi-
transparent, and veiy distinct ; the segments overlap
one another, and in the 3 or 4 segments the septa
form a fork-like arrangement ; the foramina are
clearly seen with a low magnifying power. This
one, with figs. 33 and 34, I cannot name, and I should
feel obliged if anybody could help me to name it.

Of the genus Textularia, small, transparent, and
perfect specimens were very common, but the larger
end opaque ones rare. Five species of Textularia
were found, but there is only one of them that I can
name, and that is Textularia abbreviata, D'Orb. : it
is small, transparent, and rare. Two other species

were small and transparent. One of these I have
figured to show the points protruding from the side
of the shell. One of the opaque forms is about the
5*T of an inch in length. The chambers go down
to a fine point, are rather wide at the top, and a slight
bit wider in the middle. It is very difficult to recog-
nize the species on account of the middle portion
being covered over by some arenaceous matter, there-
by hiding the characters that in some respects
determines the species.
Of the Lagenida, some very good species here
represented this family. The first of these is the
neckless variety of Lagena sulcata, Walker and Jacob.
It is a small form, and rather rare : only one of the
three specimens obtained show the lines that traverse
the shell distinctly. Lagena globosa, Montagu (see
fig. 26). This form is very small and rare. It is a
globular shell without any strire or foramina visible.
Lagena disto?na politia, Parker and Jones. This
is an elongated species, having the neck about half
the size of the body. All three of these species of
Lagena have been figured by Messrs. Parker and
Jones in their paper on the Arctic Foraminifera, in the
Philosophical Transactions for 1865, Part I. Cris-
tellaria rotulata (fig. 36), Lamarck ; small and middle

size, rather rare. A good specimen, showing the
septa well. Another peculiar species is an elongated
form traversed by rather deep furrows, as in
Lagena sulcata, with the septa placed in rather
irregular positions. Four good examples were ob-
tained, all showing different characters (see fig. 34).
The Miliolida family was here represented by three
very characteristic species. The first was Triloculina

oblonga (?). These were very minute and indistinct ;
rather rare. Biloadina ringens: this is a most
beautiful and perfect specimen ; it is of a white
colour and middle size. Rare. Spiroloculina canalicu-
lata, D'Orb. (fig. 37). Two perfect examples of
this species were found, showing the character of the
genus well. Small and rare.
In this short paper I have endeavoured to give an
idea of the character of the Foraminifera found at
Shetland. I have not given all the species found
there, and only those that I possess myself. I have
drawn the figures myself, without the aid of the
camera lucida. In my research among this bit of
sand I find that nearly all of the Foraminifera are of

NOTES ON THE DEVELOPMENT OF
FROG'S SPAWN.
By A. M. M'Aldowie, M.B.,
Member of the North Staffordshire Naturalists' Field Club.
PROBABLY no animal is better known, from an
anatomical and physiological point of view,
than the Common Frog. Developmentally the frog
has been specially studied, on account of the inte-
resting metamorphoses through which it passes before
it arrives at maturity, and also on account of the
advantages which its egg offers for the examination
of the ovum, the transparent albuminous covering
affording unrivalled facilities for observations on, and
experimental investigation into, the subject of deve-
lopment. The microscopic structure and changes
a brownish colour, showing that the water is impreg-
nated with oxide of iron ; also that the Globigerina
are dwarfed and thin, owing to the shallowness of the
water, 120 fathoms, whilst the same species from
the Atlantic, at a depth of 1,450 fathoms, are larger
and more bulky. And this gives the fact that the
Globigerina grow larger and more bulky in deep water,
whilst they are dwarfed and thin in shallow water.

which are observed during the development of the
embryo of the frog, are described and figured in
most text-books of comparative physiology and his-
tology, but the ordinary naked eye appearances and
modifications which it exhibits are not to be found in
these works. Nearly all zoological manuals give a
series of illustrations representing the various stages
in the development of the tadpole after its escape
from the egg, but they do not figure the alterations
which take place previously, without which the series
cannot be considered complete. St. George Mivart,
although he details the process of yolk subdivision
and cleavage, and the other microscopic changes
through which the embryo passes, yet with regard to
the naked eye appearances he merely states,* "Gra-
dually the embiyo assumes the form of a young tad-
pole, and is provided with a pair of little ' holders '
(or organs for adhesion), just behind the mouth, with
six openings on each side of the neck, and with a
pair of rudimentaiy external gills. " Huxley, in what
is undoubtedly the best work on the frog extant, in
reference to this subject says,f "While still within
the egg the embryo assumes the form of a minute
fish, devoid of limbs and with only rudiments of gills,
but provided with two adhesive discs on the ventral

to draw the attention of some of the readers of
Scie>."CE-Gossip to this interesting subject during
the season which is now approaching. I intended to
supplement them the following year, but had no
opportunity of doing so.
About the end of March, 1874 (exact date uncer-
tain), I exposed a mass of frog's spawn to the light in
a glass tank, placing it in a window having a westerly
aspect. There was no fire in the room. The small
round ovum (fig. 41) gradually became elongated,
assuming at first an ovoid form, but afterwards one
end became attenuated, while a small groove formed
near the other extremity, and on the 4th of April
most of them presented the appearance shown in
fig. 42. As the embryo enlarged, these characters
became more marked, until, on the Sth, the form of
the head and the body could plainly be detected
(fig- 43)-
April Sth. Most of the embryos show signs of
animation. The movements consist of alternate
flexion and extension of the body, the animal folding
itself up laterally and then straightening itself at
intervals of about half a minute. Movements first
observed in the afternoon, and continued till sunset.
April 9th. Movements more active than yester-
day, but still as restricted as before.
April 10th. Movements not quite so quick as
yesterday, but more extensive and fish-like.
April nth. Most of the tadpoles appear to be
trying to free themselves from the albuminous mass
by quick wriggling movements. External gills very
plainly seen on all (fig. 44). They first appeared as
two small protuberances, situated one on each side of
the hinder part of the head. These gradually elon-
gated, divided and subdivided, until they presented
the appearance of small branched filaments.
April 1 2th. Tadpoles all out this morning. Ar-
range themselves in clusters with their heads all in
one direction. Most of them remain quite motion-
less, but a few swim actively about the tank.

A GOSSIP ABOUT NEW BOOKS.
THE present winter has not been remarkable for
the number of scientific books issued. When
wars and the rumours of wars prevail, and the reading
world has its taste demoralized by the vivid descrip-
tions of such rapidly-succeeding events as those which
have marked the history of the last six months, it is
hardly to be wondered at that scientific literature
should retreat almost to the vanishing-point. But
there is a break in the clouds, and thoughtful people
are hoping that the storm will clear away as fast as
it gathered ; then we shall return to soberer literature
than war and anti-war newspaper leaders, with a sense
of relief and a fervent thankfulness for our narrow
escape.
Notwithstanding the paucity in the issue of first-
class scientific books, the appearance of a new volume
from the pen of Darwin is always sufficient to create
interest. And perhaps of the works which that in-
dustrious author has recently published, none is more
important than the present work, entitled, "The
Different Forms of Flowers on Plants of the same
Species " (London, John Murray). Herein Dr. Dar-
win has entered into the minutest and fullest investi-
gation of the inner structures of flowers. We now
find how abundant are the phenomena of trimor-
phism and dimorphism (only a few years ago deemed
so peculiar and exceptional), and that the number of
species bearing cleistogamic flowers is also being added
to every day ; that the latter structure of flowers,
produced by exceptional circumstances, varies from
one extreme to the other, and that these extremes
are connected by an inosculating series. Thus the
Grass Pea (Lathy?-us nissolia), bears cleistogamic
flowers, which can hardly be told from the ordinary
flowers just before the latter finally expand. At the
other extreme we find cleistogamic flowers which are
actually fertilized beneath the soil, and so are little
above the condition of subterranean buds. Dr. Darwin
further enters into the sizes and shapes of the pollen-
grain produced by different-sized stamens in dimor-
phic and trimorphic plants. The absolute necessity
for crossing to be produced, by the pollen from the
flower of one plant being carried to the pistil of
another plant, comes out strikingly in Dr. Darwin's
experiments ; for it is proved that very little is gained
by the pistil of a flower being fertilized by the pollen
of another flower borne by the same plant. The
origin of monoecious and dicecious flowers, of nectaries
in flowers, and many other singular and striking
botanical peculiarities, are here discussed in the easy
but philosophical style for which all the author's
books are celebrated. It is truly a rich treat to the
botanist to peruse such a book as this, and one to
which all our readers who have not yet read it will
thank us for attracting their immediate attention.
"The Antelope and Deer of America," by John
Dean Caton, LL.D. (London, Triibner & Co.), is a
handsome treatise upon the natural history, including
the characteristics, habits, affinities, and capacity for
domestication, of the Antilocapra and Cervidce of
North America. This is a question of the deepest
importance in practical natural history, and one which
has been too much neglected. Books on wild animals
usually tell us more about their destruction under the
name of "sport " than of possibilities of their domes-
tication and utilization. Dr. Caton tells us he has
for many years kept in domestication the American
antelope, and all of the American deer of which his
book treats, except the moose and the two species of
reindeer. 1'his book deals with the important and

■which leaves nothing to be desired. The structural
affinities and habits of the various kinds of deer, and
their comparison with each other, are most clearly set
forth. To a zoological student this book has a pecu-
liar and special value. The woodcuts are numerous,
original, and well done.
"Proteus; or, Unity in Nature," byC.B.Radcliffe,
M.D. (London, Macmillan & Co.), is the second
edition, revised and brought up to the newer views of
science, of a book which created some attention when
it first appeared some years ago. Practically it is
quite a different volume to what it was then, when
the disturbing theory of evolution was either unknown
or ignored. Dr. Radcliffe is an opponent of evolu-
tion, and although not a prejudiced one, we cannot
help feeling he has not taken sufficient pains to fully
understand it. Apart from this we have read his
book with sincere pleasure and profit. It most
thoughtfully and reverently discusses the many-
changing varieties of Nature, physical, animal, and
vegetable ; and dry facts and their relations light up
with the glow of the author's genius. The literary
style is of the most attractive character, not demonstra-
tively fervid, but chaste and yet enthusiastic.
"Physiography," by Professor Huxley, F.R.S.
(London, Macmillan & Co.), will be hailed with
pleasure by science students. Although we do not
like the new name with which the South Kensington
authorities have replaced the older one of Physical
Geography, Professor Huxley shows us in this hand-
some and well got-up volume how natural pheno-
mena may be studied in the concrete, even in their
relation to our earth, in a wider and deeper sense,
perhaps, than was undertaken in the science of
physical geography. The author eschews the old
system of treatment in works on physical geography,
wherein the readers were first taught about the shape
and motions of the earth, &c, and begins just at the
other end, leaving such astronomical facts to be dis-
cussed last. The river Thames, in fact, is employed
as a sort of scientific text, and Professor Huxley
makes its relations and associations the groundwork
of a general description which will answer almost
equally well for any other river and river-valley in
the world. The plan is admirably worked out, as
we might reasonably expect it would be at the hands
of such a master.
"The Origin of the World," by Dr. J. W. Dawson
(London, Hodder & Stoughton). Dr. Dawson is
well-known as an ardent field geologist, and one who
has largely and successfully contributed to the vast
storehouse of geological knowledge. Unfortunately
he appears to us to be an equally ardent theologian ;
and so, when he writes books on geology in general
(and he always writes them well and attractively), he
cannot forget the theological bayonets against which
the stony science has been repeatedly impelled. The
consequence is a melange of geology and theology,
which we are afraid is not of special advantage to
either. Especially is Dr. Dawson angeied with the
theory of evolution, and he loses not an opportunity
to tilt against it, frequently with as much success as
Don Quixote's similar attempt to overthrow the
windmills. The present volume is especially satu-
rated with what Professor Huxley calls "Mosaism";
one almost feels as if we had gone back to the time of
Hugh Miller. But there are many readers who are
fond of discussing the many points of contact which
still exist between Genesis and geology ; and to such
we can confidently recommend Dr. Dawson's book
as likely to please them in no ordinary degree.
"Accidents in Mines: their Causes and Preven-
tion," by Alan Bagot, Mining Engineer (London,
C. Kegan, Paul, & Co. ). In this small but attrac-
tive volume the author has collected all the informa-
tion possible, as seen by those who are engaged pro-
fessionally as mining engineers, in order to its being
brought before the public. He discusses whether the
principles of Davey's Safety-Lamp hold good when
the atmospheric pressure is as great as we find it in
deep coal-mines. Also, what effect the vibrating
waves of sound may have on the flame within the
lamp when the latter is surrounded by an explosive
mixture of gas. Mr. Bagot thinks that in the solution
of these two problems lies the secret of explosion
after shot-firing in mines. In the eighteen chapters
which compose this book, the author enters most
fully into the economy of coal-mines, and all that
concerns their safe and effective working. The work
is therefore a most valuable one, and ought to be in
the hands of all those whom the subject directly or
indirectly concerns.
A REMARKABLE GARDEN PLANT.
( Thunbergia alata. )
THIS very pretty tropical climber, belonging to
the natural order Acanthacecc, a native of India
and Madagascar, was introduced to our gardens some
fifty years ago. It presents in the structure of its flowers
numerous points of interest. The plant is a slender
twiner, with hastate leaves, whose petioles, as the
specific name alata, implies, are broadly winged.
The calyx is very minute, consisting of twelve hair-
like sepals, its place being occupied by two large
membranous, almost transparent, bracts. These are
strongly keeled, and overlap each other, completely
enveloping the calyx, and about one-half of the corolla
tube. Besides the keel, there are about six well-
marked longitudinal veins, connected by numerous
smaller ones almost at right angles, forming a rect-
angular network somewhat resembling that of Ouvi-
randra fenesiralis. The whole surface is beset with
scattered hairs, which are either simple, or with one
or two septa, and bent where the septum occurs.
They are hollow, except at the nodes and near the
points, the hollow portion terminating in a bulbous
56

expansion similar to a nettle-sting. There is but little
chlorophyl, a large portion of the bract being occu-
pied by air-spaces, into which numerous long, narrow
stomata open. The corolla is salver-shaped, slightly
oblique, and of a clear Nankeen yellow, the colour
being somewhat brighter round the throat. In some
forms the throat is a dark chocolate-brown, almost
black, while in one variety the limb is pure white
with a dark throat. The stamens are four in number,
and are situated far down in the tube of the corolla,
the interior pair being considerably shorter than the
exterior pair. The filament is inserted into the dorsal
portion of the connective, a short distance from the
base of the anther, thus giving the ventral face of the
anther a slight inclination forwards and upwards.
Fig. 45. Diagram of flower of Thunbergia alata (vertical
section).
The anthers adhere by the ventral suture, the pro-
jecting margins of the lobes being densely bearded
with hairs of a peculiar and interesting form. They
are slender and clavate, consisting of numerous joints.
The lower are oblong, three or four times as long as
broad. Proceeding from the base upwards, the joints
become shorter, thicker, and more rounded, and with
deeper constrictions, giving a beaded appearance, the
uppermost one being frequently divided by vertical
septa into two or three. These topmost cells are
some twice or thrice the diameter of what I may term
the stem of the hair, the whole of which, from base to
summit, is finely tuberculated, the tubercles increasing
in number and size from below upwards. A trace of
this tuberculation occurs also on the hairs of the bract,
but to a very much smaller degree. The pollen,
which, like the anthers and the anther hairs, is almost
white, is spherical, and has several broad, flat, spiral
grooves winding round it in opposite directions, pro-
ducing a very curious appearance. The pistil is long
and slender, passes up between the interior and
shorter pair of stamens, and, like them, is closely
! adpressed to the back of the corolla tube. The
stigma, which is situated a short distance above the
upper stamens, appears to consist of two parts. The
upper portion is the style slightly flattened and curved
round into a kind of a narrow funnel, at the base of
which, and on the front of the style, is a semicircular
cup-shaped body, which seems to be a further develop-
ment of the stigma, as I have observed numerous
pollen-grains adhering to its viscid edges. The con-
cave surface of this cup is upwards, the convex down-
wards. Thus it appears that every precaution is taken
to avoid self-fertilization. The corolla is almost erect,

Fig. 47. Hairs of bract of Thunbergia X 50.
the stamens densely bearded on the ventral or front
side, with hairs pointing downwards, which hairs, still
further to retain the pollen from any accidental dis-
turbance from wind, Sec, are club-shaped, thickened
at the apex, and closely tuberculated, while the
pollen-grains themselves have spiral grooves to
increase their tenacity to the hairs. Again, the stig-
matic surface is turned directly away from the pollen,
so that it is scarcely conceivable that self-fertilization
could take place. Suppose an insect with a long pro-
boscis visits the flower, its proboscis passes down-
wards freely to the base of the corolla ; on with-
drawing it, the trunk cannot fail to brush upwards or
backwards some of the anther hairs, and in so doing
set free some of the pollen which adheres. The
horizontal and non-stigmatic portion of the pistil
being downwards, receives none of the pollen. The
insect visits another flower, and thrusts its proboscis,
laden with pollen, into the corolla. In so doing, the
stigma being in a narrow portion of the tube, is
nearly certain to intercept some of the grains, and
thus ensure fertilization. Even should this fail,
touching the base of the style causes it to bend for-
ward, and thus be ready for the next comer. The

truth of this is readily proved, for flowers which are
"set" artificially freely produce seed, while those
left to themselves, being grown under glass, and thus
out of the reach of most insects, never come to matu-
rity. The seed-vessel is somewhat curious, as well as
other parts of the plant, being in shape a flattened
sphere with a long beak, and contains two to four
hemispherical rough blackish seeds. Altogether,
whether as botanical curiosity, or a garden ornament,
this Thunbergia is well worth growing.

THE POTATO-BEETLE.
IN thanking Mr. W. V. Andrews, the Correspond-
ing Secretary of the Long Island Entomologists'
Society, U.S.A., for his kind and complimentary
allusions to myself on page I of the present volume,
I am reluctantly compelled, as he classes me " in the
ranks of the alarmists," to conclude either (i) that I
have, in my article on the Beetle in question, in
Science-Gossip of 1st September last, acted un-
wittingly upon the principle that language is given us
to conceal our thoughts ; or, (2) that Mr. Andrews
does not thoroughly understand the English tongue.
There is some slight excuse for the first hypothesis in
my remarks upon South Kensington on p. 202 ; and
it is humiliating to have to point out, even to an out-
sider, that these were "written sarkastic," as the
great Artemus says. For the second one, I must
refer to my express statement, on p. 203, that " to
the writer it seems that our much damper and colder
climate, not affording opportunities for the rapid suc-
cession of broods which the insect develops in
America, must materially militate against its obtaining
a permanent hold ; and the collateral arguments, that
no American beetle has ever established itself in Eng-
land, and that we possess no near ally of this parti-
cular one, cannot fail to have some weight in the
matter." The fact is, that to every Coleopterist of
my acquaintance, and to every one (the name is
legion) with whom I have had conversation on the
subject, it is well known that I have from the first
steadily and strenuously been opposed to any belief
in the idea that the potato-beetle could be of any
harm in this country ; and this view I have always
upheld in everything I have written. Indeed, I have
a firm conviction that, if circumstances had not pre-
vented the present Editor of Science-Gossip (long
may he reign !) from attending the Plymouth meeting
of the British Association, where there was much
talk, post-prandial and otherwise, upon this subject,
the false conclusion as to my being among the alarmists
would never have appeared — at all events, without
simultaneous correction.
Mr. Andrews says : — •" Mr. Rye tells you that Paris
green is a favourite remedy here, but he does not
understand the American mode of doing things.
Some State entomologist or other probably had a
friend in the oil or colour business," &c, and, " You
do not do things in that way in honest old England,
but we do here." Without going so far as to quote a
homely Saxon proverb, concerning a certain ill bird
and its nest, I must, remembering Riley, Le Baron,
Packard, Cyrus Thomas, and other "good men and
true," of whose scientific help the U.S. Government
has wisely availed itself, energetically disclaim the
acceptance of such remarks as these as a sample of the
" Science-Gossip " of the States. It is to the first-
named of these authorities that we owe most of our
knowledge of Transatlantic economic entomology ;
and his reputation is far too securely established to be
shaken by the insinuations of even the Corresponding
Secretary of the Long Island Entomologists' Society.
That gentleman's concluding caution to English
readers, that all striped beetles found on potatoes are
not Colorado beetles, but may be useful little fellows,
&c, shows an ignorance of our Insect Fauna, re-
markable in one who proposes to allay our (hypo-
thetical) fears. E. C. Rye.
NOTES FROM WEST KERRY.
ONLY a few species of Cetacea are known to
frequent the Irish coast ; the common por-
poise is of every-day occurrence ; the pilot-whale
{Globioceplialus Svineval) is often met with in large
numbers, and an immense B alalia is occasionally
cast on shore. All the smaller species of Cetacea are
termed " Porpoises " by the Irish peasantry, who
value them, not only as excellent food, but attribute
to their flesh and oil hygienic and medicinal proper-
ties. Consequently, whenever one or more happen
to be stranded, they rush in crowds with scythes and
sickles, hatchets, pitchforks, spades, knives, and all
manner of deadly weapons, to the scene of the occur-
rence, hew, hack, decapitate, and cut into fragments
the unwieldy stranger, and long before rumour of the
capture has reached any educated person, the coveted
flesh is stored away in tubs, or piled in a corner of
some sooty cabin ; the entrails and useless viscera
thrown into the receding tide or torn by hogs (the
dear and cherished associates in Irish cabins of scro-
fulous children and of their filthy parents), and so
far as science is concerned the unfortunate fish, seal,
or cetacean, might as well have remained in his
marine abode. On a March morning in 1S64, on
the shelving sandy beach of Fermoyle, skirting the
waters of Brandon Bay, on the west coast of Kerry,
I observed two men moving a heavy object, which
on closer inspection proved to be part of the head of
a cetacean such as I had never before seen. The
head had been much larger, and divided vertically
behind the eyes ; the front portion only remained ;
the eyes, however, were left untouched, as also the
lunated spiracle, with the concavity looking forward.
53
HA RD WICKE >S S CIE NCE - G O SSI P.
The measurements in the recent state of the animal
were —
From centre of fold of spiracle to each eye, 10 in.
From same point to extremity of upper jaw, 22 in.
From commissure of lips to extremity of upper jaw,
13J in-
From same to extremity of lower jaw, 14 in.
On the lower surface of the integuments corre-
sponding to the space between the rami of the lower
jaw, was a well-defined angle, formed by two de-
pressed lines, or furrows, each ten inches long.
These lines converged to an apex in front, while
their extremities behind were seven inches apart.
The acute angle thus defined corresponded, I say,
externally with an almost equal internal angle, formed
by the convergence of the lower jawbones, and giving
accommodation to the deep pouch of the pharynx, as
shown in my illustration With the kind assistance of
my friend, Mr. R. Conway Hickson, whose finely-
placed residence at Fermoyle is in the immediate
vicinity of the scene of capture, the remains of the
head were rescued from the destroyers and conveyed
to Carthgregory, a neighbouring village, where scien-
tific appliances are scarcely more numerous than
"strawberries grown in the sea." However, under
unfavourable circumstances four or five photographic
illustrations were obtained from it — riot artistic, cer-
tainly, but affording correct ideas, for the first time,
I believe, of the physiognomy of the curious creature.
Eagerly, as you may suppose, and at once, I con-
sulted the few authorities within my reach, and found
that this remarkable cetacean had not been pre-
viously recognised as a visitant of the Irish coast,
nor of Great Britain, save once before, in 1 790. In
Jardine's "Naturalists' Library" it is described and
figured as Diodon Sowerbii, but the Plate there
given has little resemblance to the animal, and none
as regards the beak, its most conspicuous peculiarity.
It is described, though not figured, in the " English
Cyclopaedia, as "Ziphius Sowerbii," and that is
now its recognised appellation.
The genus "Ziphius" is remarkable chiefly for
its elongated jaws, which extend to, at least, a length
of fourteen inches from the commissure of the lips,
and form a beak or snout of great solidity and
strength. The upper fits into the lower as a cylinder
into a semi-cylinder. Before the lower jaws con-
verge to form this semi-cylinder, and posterior to the
point where the front of the pharyngeal pouch is
attached to the bone, one stout pyramidal tooth is
inserted in a deep socket on each side of the lower
jaw ; thus the tooth is nine or ten inches from the
extremity of the beak. The soft parts on the upper
jaw are notched on each side for the reception of the
high projecting tooth ; these teeth are believed to be
characteristic of the male. Though found in the Scotch
and Irish animals, there are a few specimens in Con-
tinental museums from which they are absent ; this
absence was supposed by some to indicate difference
of species, by others to be merely a sexual distinction.
The genus Ziphius is comparatively new to Natural
History. Nothing was known of it till some fossil
remains were sent from Holland and from the south
of France to Cuvier, who, not being then aware of
any existing cetacean with similar beak, supposed
the remains to belong to an extinct genus. The dis-
covery in Scotland, in 1 790, proved that this supposi-
tion was erroneous, and a very few living specimens
met with since have shown that Ziphius does exist in
modern seas. Still they are extremely rare, and an
unmutilated specimen would be of great anatomical
interest, and its skeleton a desideratum in any museum.
In 1870, after a lapse of six years, it was my fortune,
alone of all men, I believe, to meet with a second
Ziphius, about five or six miles from the site of the
first capture. This time the animal came in near
Brandon Pier, a very interesting and well-known
fishing-station, worthy of more remark than would
be relevant here.
Before I saw it, it had been treated like its prede-
cessor ; its flesh had been cut into a thousand pieces
by the greedy peasantry, and its bones unscientific-
ally sawn and broken. I snatched a portion of its jaw
from a dog's mouth, and disinterred parts of the split
skull from a dungheap ; and I dragged some portion
of the skeleton, as well as part of the stomach which
pigs had not torn, from the ebbing tide. The intes-
tines generally were so mangled as to be useless for
anatomical purposes ; nor could any part of the solid
viscera be obtained. An irregular hole, whose largest
diameter may have been an inch, had been made in
one compartment of the stomach, which I had taken
from the tide-covered sand, and this compartment
was completely filled with sand. I do not think it
probable, or even possible, that the sand could have
entered through the accidental aperture while for a
short time under water. I cannot offer any explana-
tion of hozv or why it was there ; but who will affirm,
in our total ignorance of the habits of the animal,
that he did not swallow it during life, impelled by
some unaccountable physiological necessity, or per-
haps from -depraved appetite, the result of disease ?
I opened what seemed to be a second compartment
of the stomach, when more than a pint of bile rushed
out. Anatomists have denied a gall-bladder to zoo-
phagous cetaceans, but what was this ? — or is ziphius
not zoophagous ? Nothing but sand and bile existed
in these viscera ; I was much pressed for time, and
could not examine more closely into the matter, but
sent both stomach and bile to Dublin to competent
investigators.
Ziphius No. 2 was about seventeen or eighteen feet
long, and was first observed on the beach at high
water, in great uneasiness, floundering, and, of course,
working a cavity in the sand, in which it remained
when the tide had ebbed. When first approached
by its butchers it was seen to open its cylindrical
jaws in a portentous way, and to close them with an

angry snap, while from each tooth stood out laterally
two or three large barnacles, giving it a wild and
extraordinary appearance. Of these cirripedes only
parts of the peduncles remained when I got posses-
sion, but, as the captors said, they were not common
barnacles (Lepas Anatifera), so well known to all
dwellers on the sea-coast ; I am inclined to believe
they were another well-known species {Conchoderma
Aurita). The presence of these barnacles seems to
discountenance an opinion which some might rashly
entertain, that the sharp strong teeth, if not confined
to the male, were used to impale the animals' prey,
while being crushed by the powerful beak ; but if
such were the case, the impudent and daring guests
would be rubbed off before they could become firmly
fixed to their strange abode, so close to the maw of
their monstrous host. On the other hand, the ex-
tremely sharp point of the tooth would seem to
indicate constant use. As to the colour of the
animal, the skin on the head of the Fermoyle speci-
men was of a glossy satiny black, badly represented
in the photograph, owing to the reflection of light,
but I cannot now speak with certainty of the mouths
proper and the tongue. In the Brandon Pier speci-
men I cannot speak of the head, but the deep pha-
ryngeal pouch was of the usual reddish colour of
mucous membrane. I obtained a few square pieces
with the natural skin, not torn or gnawed, black and
glossy, but vermicularly marked with white streaks,
up and down and across, in irregular network. Many
of the "streaks bore a singular resemblance to old
cicatrices — scars from greedymarine warriors, inflicted,
perhaps, by grampuses or sharks. Though I will
vouch for it that Ziphius himself, if angry or jealous,
could give a sharp nip to an enemy or rival, yet I do
not believe that these teeth were given for attack or
defence ; if fixed at the point of the beak, they would
be powerful instruments for either species of warfare.
One of the spectators asserts, that when first stranded,
the unhappy animal "roared like a bull." Another
insists that he was perfectly silent. In this, as in
almost every case, I would be inclined to believe the
less sensational witness.
A recital of the synonyms applied to our long-
beaked friend — ungallantly assuming that the tooth-
less specimens are the females — would fail to interest
your readers. Diodon, Physeter, Delphinorynchus,
Mesodiodon, Dioplodon, Mesoplodon, are a few of
the jaw-breaking epithets, dangerous to any jaw less
mighty than its own! "Ziphius Sowerbii," like
Aaron's Rod, has swallowed the others.
My friend, Mr. William Andrews, the zealous and
learned naturalist who has done so much for Irish
Natural History, and especially for that of West
Kerry, has given them all, and much information
besides, in an excellent paper read to the " Royal
Irish Academy," descriptive of Brandon Ziphius No. I,
to which I may refer all readers for information be-
yond the scope of my " gossip."
I placed the few fragments of skeleton No. i at the
disposal of Lord Ventry, and of No. 2 at the disposal
of Mr. Andrews, and I believe they are now in the
museum of the " Royal Dublin Society."

THE SEALS AND WHALES OF THE
BRITISH SEAS.
No. VIII.
By Thomas Southwell, F.Z.S., &c
ONE more British Ziphioid is known, Sowerby's
Whale {Mesoplodon Sowerbiensis, De Blain-
ville) ; it was first described from a specimen which
came ashore at Brodie, Elginshire, in 1800, and has
since been found three times in Ireland ; there is also
a skull in the Museum of Science and Art at Edin-
burgh which belonged to a specimen believed to have
been captured somewhere on the Scotch coast ; the
remains of five others are preserved in various
Continental museums.
Of the individual which came on shore on the
coast of Kerry, in March, 1864, Mr. Andrews has
given a description in the " Transactions of the Royal
Irish Academy," for April, 1867. Fortunately it
came under the notice of Dr. Busteed, of Castle
Gregory, who being interested in zoology, and aware of
the great importance of the occurrence, photographed
the head in several positions while it was yet fresh :
Dr. Busteed's photographs were reproduced in the
Transactions of the Royal Irish Academy. The head
had unfortunately been removed immediately behind
the frontal portion of the skull, the base of which is
lost, as also the other parts of the skeleton. The total
length of the animal was about fifteen feet, the two
teeth largely developed and projecting like the tusks
of a boar ; these teeth are believed to be developed
only in the males. On the under part of the throat
the V-shaped furrow was very conspicuous. Sowerby's
specimen was coloured black above, and nearly white
below. The skin smooth like satin. ' ' Immediately
under the cuticle the sides were completely covered
with white vermicular streaks in every direction,
which at a little distance appeared like irregular cuts
with a sharp instrument."
The remaining family, Delphinida, as has been
said, is a very numerous one, it has ten representatives
in the British fauna, contained in seven genera,
the first of which, according to the arrangement I
have adopted, is that of Monodon. The Narwhal
{Afonodon monoceros, Linn. ) is a native of the Polar
seas, seldom leaving the ice ; stragglers have occurred
three times on the British coast, one in 1648 in the
Firth of Forth, another came ashore alive at Boston,
in 1800 ; the third was taken in Shetland in 1S08.
This species is very numerous in the frozen seas
to the north of latitude 650, and is remarkable
6o

for the enormous development of the left canine tooth,
which is projected forward in the form of a tusk or
a spear, reaching to the length of six or eight feet.
The spear is of fine compact ivory, hollow for the
greater part of its length, grooved spirally along its
outer surface, but smooth at the end, and bluntly
pointed. The right canine is rarely developed, but
a few examples have occurred in which both tusks
were present (see Proc. Zool. Soc, 1S71) ; the female
is rarely furnished with this appendage. Not long
since I saw preserved in a country mansion, the tusk
of a Narwhal measuring 7 ft. 5 in. long ; it was care-
fully kept in a long case resembling a barber's pole,
tusk, which is frequently found in a broken condition,
is used for purposes of attack and defence. The
Narwhal is very social in its habits, great numbers
being often met with together ; its food consists of
cuttle-fish and crustaceans. The length of the full-
grown animal is about 16 feet, the upper parts gray,
the sides and belly white, and the whole animal
spotted with black and gray. The only authentic
figure of the Narwhal with which I am acquainted is
that given by Scoresby ; this is so well known from
frequent reproduction that it is not necessary to give
it here.

and bore a ticket attached, which stated that it was
" Bequeathed in 1561 by the Countess of ■ , to
her daughter ." The use of this remarkable
appendage appears very doubtful ; it has been con-
jectured that it serves to stir up food from the bottom
of the sea, in which case the female would be badly
off without it ; or that it is employed to keep breathing-
holes open in the ice, and an instance is related in
support of this view, in which hundreds were seen at
an ice-hole protruding their heads to breathe, but it
is not clear whether they made the hole for them-
selves, or whether they were attracted by it,
particularly as there were numbers of White Whales
with them. It seems certain, however, that the
lucas, Pallas), like the preceding species is a native
of the Polar seas, where it is common; it is abundant
in the White and Kara Seas and in the Gulf
of Obi ; on the coast of Norway it is occasionally
met with ; and in our own seas has occurred
several times, but must be regarded only as an
accidental straggler. On the east coast of America
it is found as far south as the Gulf of St. Lawrence,
where, as in the White Sea, it delights in ascending
the mouths of large rivers. In the British Associa-
tion Report on the Fauna of Devonshire (1S69, pp. 84
and 85), occurs the following passage. " Mr. P. H.
Gosse writes :— 'On August 5th, 1832, I was return-
ing from Newfoundland to England, and was sailing
HARDWICKE'S SCIENCE-GOSSIP.

up the British Channel close to the land, when just
off Berry Head, I saw under the ship's bows a large
cetacean of a milky-white hue, but appearing slightly
tinged with green from the intervening stratum of
clear water. It was about 16 ft. long, with a round,
bluff head. It continued to swim along before the
vessel's head, a few yards beneath the surface, for
about ten minutes, maintaining our rate of speed,
which was five knots an hour, all which time I
enjoyed from the bowsprit a very good view of it. It
could have been no other than the White Whale, the
B. borealis of Lesson.' " The whale lately exhibited
at the Westminster Aquarium belonged to this
species; unfortunately it did not live to equal in
docility and intelligence a specimen exhibited in
kill great numbers, extracting the oil and drying the
flesh for winter use ; in Russia, the prepared skin
is much used for reins or other parts of harness
requiring great strength and lightness. The length
of the full-grown animal is about 1 6 ft., and its food
consists of fishes, Crustacea, and Cephalapods.
The common Grampus or Killer {Orca gladiator,
Lacepede), (fig. 48) is a well-known and widely dis-
persed species, being found in both the North Atlantic
and Pacific Seas. Andrew Murray says "the common
Grampus tumbles through the heavy waves all the way
from Britain to Japan, viA the North-west Passage."
In the British seas it is frequently met with, and has
occurred in several instances on the coast of Norfolk.
This species is very fierce, its appetite insatiable, and

and would allow himself to be handled by him, and at
the proper time would come and put his head out of

DelphiiiKS tursio which was for a time with him in
the same tank, is said to have been even more docile
than this remarkable animal.* The adult Beluga is
pure white, and a "school "of these animals "leaping

very beautiful sight. In summer the Greenlanders

carnivorous in the strictest sense of the word ; to the
Greenland and White Whale, as well as to porpoises
and seals, it is an implacable enemy, and follows
them ruthlessly. Dr. Brown says, ' ' the White Whale
and seals often run ashore, in terror of this cetacean,
and I have seen seals spring out of the water when
pursued by it. The whalers hate to see it, for its
arrival is the signal for every whale to leave that
portion of the ice." Eshricht took out of the
stomach of a Killer, 21 ft. long, which came ashore
in Jutland, no less than thirteen common porpoises
and fourteen seals.
The rounded, compact form of this species gives the
idea of great strength and swiftness, and the beautifully

polished glossy black skin of the back contrasting |
with the equally pure and well defined white of the
lower parts has a very striking effect ; altogether it is
a very handsome species, but there is something in
its appearance which seems to indicate its cruel
nature. The adult Killer measures about 21 ft. in
length, the back is pure black, the under parts white^
and over the eye is a well-defined white spot ; there
are thirteen or fourteen strong, slightly curved teeth
on either side of both jaws ; the flippers are broad
and oval shaped, the dorsal fin high, particularly in
the male.
As these papers are intended for the purpose of
assisting in the identification of casual visitants to our
shores rather than of giving anything like a history of
the known British species of Cetacea, it may be
desirable to mention here a very remarkable form,
which although it has never been known to occur in
the flesh on our shores, was first made known to
science from an imperfect skeleton found in a semi-
fossil condition beneath the peat in a Lincolnshire
Fen. To this Dolphin " come back as it were, from
the dead," and which forms a connecting link between
the genus Orca and the genera Grampus and Globi-
cephalus (and which Owen had named Phocana
crassidens), Reinhardt gives the name of Pseudorca
crassidens. On the 24th November, 1861, a large
shoal of these dolphins made their appearance in the
Bay of Kiel, about thirty of which the sailors suc-
ceeded in separating from the remainder, but all, with
one exception, escaped. This was a female i6feet long,
which after being exhibited at Kiel and other places,
was bought for the collection of the University of
Kiel. In the summer of 1862, three other individuals,
presumably from the same shoal, were thrown ashore
on the north-western coast of Zealand. Of the general
appearance of this creature the accompanying
figure (49), copied, by kind permission, from Pro-
fessor Flower's translation of Reinhardt's paper
read before the Royal Danish Society of Sciences
in 1S62, and published by the Ray Society,
will give an idea ; the figure is from a photo-
graph of the Kiel specimen, and is not in the
original paper. The length is from 16 to 19 feet ;
of the colour no account is given, but judging from
the woodcut of the Kiel specimen it appears to be
uniformly shiny black. The number of teeth differs
in individuals, but in this one it was from 9 to 10 on
either side of the lower jaw, and 8 to 10 in the upper.
From the observations made by Reinhardt, he suggests
the possibility that there may be " a difference in the
sizes of the different sexes, and whether the females
are not larger, but at the same time, perhaps, provided
with a head comparatively smaller than that of the
males." It is very suggestive of how little we know
of the inhabitants of the sea, that at least one vast
shoal of a species known only from its sub-fossil
remains should be roaming the seas only to be accident-
ally discovered when its members became entangled
in shoals from which probably many never lived to
extricate themselves.
Risso's Dolphin {Grampus griseus, G. Cuvier) is
a rare and little known species, which has been met
with four times on the south coast of England and
about eight times in France. In the "Transactions
of the Zoological Society," for 187 1, Prof. Flower
gives an account of an adult female which was taken
in a mackarel-net, near the Eddystone Lighthouse,
on 28th February, 1S70, and which eventually was
sent up to London, when it was seen and described
by that gentleman. About a month later, a second
specimen was received in London, the precise locality
of which was not known, but it was probably from
somewhere in the Channel. This was also a female,
but a very young animal, and as the adult female first
taken had recently given birth to a young one, it is
quite possible that it may have belonged to her. On
the 26th July, a male of the same species was captured
alive at Sidlesham, near Chichester, and sent to the
Brighton Aquarium, where it lived only a few hours.
Risso's Dolphin varies very considerably in its
colouration. The Sidlesham specimen was bluish-
black above, and dirty white beneath ; in the adult
female described by Professor Flower (from whose
illustration our figure is, with his permission,
copied), "the head and the whole of the body
anterior to the dorsal fin was of a lightish grey,
variegated with patches of both darker and whiter
hue. . . . Behind the anterior edge of the dorsal
fin the general colour of the surface, including the
dorsal and caudal fins, was nearly black, though
with a large light patch on the upper part of the side
directly above the pudendal orifice. The middle of
the belly as far back as the pudendal orifice, was
greyish white. "* The most remarkable characteristic
however, was the presence, scattered over the body,
of irregular light streaks and spots, these markings
extended from the head to within about two feet from
the tail and presented a most singular appearance.
In the young one the upper parts and sides of the
body were almost black, the lower parts nearly white,
the junction between the two colours being very
abrupt and sharp. " On either side the body were
six vertical whitish stripes nearly symmetrically ar-
ranged, and almost equidistant, being about six inches
apart. They did not extend quite to the middle line
of the body above, and were lost below in the light
colour of the abdomen. ™f The length of the Sidle-
sham male was 8 feet, that of the adult female 10 ft.
6 in. ; in the former there were present four teeth on
each side the lower jaw, in the latter three only on
each side, and in the immature specimen there were
present seven teeth, four on the right, and three on
the left side, the teeth are always placed in the front
part of the mandible, and in every specimen exa-

mined there has been an entire absence of teeth in the
upper jaw. In general appearance, Risso's Dolphin,
more particularly the dark-coloured specimens, is said
very much to resemble the next species {Globicephalus
melas). Of its habits and distribution nothing positive
is known, but from its visiting France or England in
the spring or summer. M. Fischer " concludes that
this species is migratory, visiting the shores of Europe
in the summer, and passing the winter either to the
south towards the coast of Africa, or to the west
towards the American Continent." *
MICROSCOPY,
Volvox Globator. — It may be interesting to
Microscopists to know that Volvox Globator can be
found in considerable numbers — although so early in
the year — in the large pond near Wandsworth Com-
mon Station. On Wednesday, Jan. 23rd, the Super-
intendent of the Sunday School here gave a treat to
the children, and we arranged to make it both in-
teresting and instructive. Having undertaken the
Microscopic department, I was examining a bottle of
fishings from the pond, and was surprised to find it
contained Volvox in great plenty. To find it so early
being quite new to me, I have inquired of several
friends, but none of them had met with it at this time.
Most of them seem to have imagined that it was use-
less to expect to find it till about the end of March.
It may be that many others have not found it for the
same reason ; and a knowledge of the fact of its being
obtainable now may be an addition to the Micro-
scopist's pleasures. While examining a portion of
the gathering, we were particularly struck with a fine
specimen, containing no less than ten small ones en-
closed. It rolled round with a motion so grand, that
all who saw it were delighted. Suddenly, while
watching it, it stopped for a moment, and then burst.
Five of the little ones escaped from the parental en-
velope. There was a distinct pause between their
liberation, and each came out with a sort of dizzy
staggering movement, and then, after a momentary
rest, would start off and commence to roll as if quite
an old hand at doing it. The other five seemed to
die, and make no sign. — IV. Winsford, Upper
Tooting.
Cleansing Old Slides. — In my paragraph on
this subject, which appeared in the January number
ofSciENCE-GossiP, p. 15, at line 4, instead of "water-
glass," read " watch-glass." In line 7 put a full stop
at "Benzole," and instead of "and use," read
" /use." — John Bramhall.
Improvement in Microscope-Stands. — Mr.
George E. Fell, of Buffalo, has recently suggested a
new addition to the microscope-stand. It consists
1. c p.
of a finely-engraved scale on that part of the body of
the stand which sides the limb. The latter can be
furnished with a vernier, giving readings as close as
may be desired.
Plant-crystals. — At the last meeting of the
East Kent Natural History Society, numerous draw-
ings were exhibited of Raphides, and other microscopic
plant-crystals, intended to be engraved on two plates
of more than forty figures. They were the work of
Prof. Gulliver, F.R.S., who gave explanatory ob-
servations thereon. Among these was the curious
and novel description, that some trees and other
plants, from stem to branches and leaves, are in-
vested by a most delicate network, or tesselated
pavement like mosaic work, of cells all studded with
splicer -aphides, so that eacli cell is set and adorned
with a gem of one of these beautiful crystals. Aralia
spinosa was said to form an example, beneath its
bark or epidermis, of this external skeleton of crys-
talline tissue. And an internal crystalline skeleton
was shown in other plants, including some Legu-
minosce, as may be well seen in the common white
clover ; the crystals being arranged in chains along
the vascular bundles. Mr. Gulliver remarked that
boiling a portion of the plant, before its examination,
in the solution of caustic potass which is kept by
druggists, exposes the crystals very clearly. He
added that he had learned that Mr. Hammond, of
Milton Chapel, had found the long crystal prisms of
Iridacece, Sec. , admirably suited for experiments on
the polarization of light ; and that the whole subject
of plant-crystals belongs to the vast domain of the
cell-biography of plants, hitherto sadly neglected, but
which must be diligently cultivated before we can
hope for the most complete system of botanical
classification, and knowledge of the laws which
govern the vegetable kingdom.
Habirshaw's Catalogue of the Diato-
mace.e. — Mr. Frederick Habirshaw, of 6, West Forty-
eighth Street, New York, to whom I am personally
unknown, has kindly sent me a copy of the above
work, which supplies a want long felt by diatomists.
To explain its plan and intention I cannot do better
than quote the short preface. "The following Cata-
logue, made for private use, contains ' the references
to the literature of the Diatoniacece, published prior
to May, 1877. At the suggestion of Prof. Hamil-
ton L. Smith, of Hobart College, fifty copies have
been reproduced by the Edison electrical pen pro-
cess, for gratuitous distribution among those specially
interested in this branch of natural history, and I
trust the errors or omissions will not be found suffi-
cient to impair the value of the Catalogue." The
volume is a convenient quarto, 11 in. x 6 in., of
some 270 pages, the first six containing a list of
the principal writings relating to the diato?nacea:,
the rest being devoted to the general catalogue. The
genera and species are arranged alphabetically, and

there must be considerably over 7,000 species enu-
merated, to each of which short but copious refer-
ences are attached, as to where it may be found
figured or described, the synonyms being also given.
As far as I have been able as yet to verify these, they
seem quite correct. Those who have been fortunate
enough to receive a copy will, of course, show it to
their friends, who will wish to obtain one also, and I
fancy Mr. Habirshaw will be induced to print off a
much larger edition, though, of course, not gratui-
tously, to supply the demand. — Fred. II. Lang,
Torquay.
Microscopic Life of the Carboniferous
Limestone. — At the last meeting of the Chester
Society of Natural History, Mr. G. W. Shrubsole,
F.G. S., read a lengthy and interesting paper on
" The Microscopic Life of the Mountain Limestone
(foramenifera, radiolaria, entomostraca, poiyzoa,
&c.)." The various objects described had been
chiefly obtained from the mountain limestone of
North Wales and the neighbourhood.
ZOOLOGY.
Turning an Enemy to Use. — The United
States Entomological Commission, which was organ-
ized for the purpose of investigating and reporting
on the entire subject of insect ravages throughout the
western regions of the United States, have discovered,
by means of chemical analysis, that dead locusts will
furnish a new oil, which will be christened caloptine,
and a very large percentage of pure formic acid.
Though this acid exists in the ant and some other
insects, it is with difficulty obtained in large quanti-
ties ; whereas, by the action of sulphuric acid upon
the locust juices, it passes off with great readiness and
in remarkable quantity and gravity. The uses of this
acid, as a therapeutic, are capable of great and valu-
able extension, where it can be obtained so readily and
in such quantity.
The Red-throated Diver. — When visiting in
Shetland two years ago, I had a capital opportunity
of witnessing the nesting of the Red-throated Diver
(Colymbus septentrionalis). Having been informed by
a Shetlander that the aforesaid bird had frequented a
certain loch the previous year, I was determined to
walk over thither, a distance of about six miles.
Accordingly I set out, but, in crossing the mountains,
encountered a very heavy shower of rain, which con-
tinued for the space of about an hour ; nevertheless
I succeeded in seeing the object of my expedition.
When on the summit of a mountain near my journey's
end, I descried the loch, and also the Diver swim-
ming leisurely about. This, however, proved to be
the male, for, on walking round the margin of the
loch, I saw the female sitting on her nest with out-
stretched neck. She permitted me to approach within
about four yards of her. When I had stood for five
or six minutes to admire her beauty, she suddenly
dived from the nest, and all my efforts to see her
afterwards were unavailing. The nest was nothing
more than a slightly hollow depression on the very
edge of the loch, and contained but one egg, of a
more elongated form than usual, of a dark brown
colour, sparingly spotted with black. — C. D. Wolsten-
holme.
Rare Birds Shot. — Lately there have been
the following rare birds shot : — A Merlin (Falco
sEsalon), shot near Wetherby on the 16th Decem-
ber, 1877; a Bittern (Botaurus stellaris), shot at
Castle Howard, on the 26th of the same month ;
and a Pied Water Rail (Rallus aquaticus), shot in
Ireland in January, 1878. The latter has a great:
quantity of white on the back ; the top of the head and
neck have also a little white about them. There is a
little white on the tail, and the tertials are nearly pure
white. — P. Thompson.
St. Mary, Lambeth, Field Club. — This most
useful and unostentatious Natural History Society
was originated about six years ago by the Sunday
School teachers of the parish, who have been very
successful in diffusing and popularising a love of natural
history. It includes about thirty members, of whom
Arthur Eve, Esq., is president, and Mr. G. Masters
secretary.
The Birds of Costa Rica. — At a recent
meeting of the Zoological Society of London, Mr. A.
Boucard, C. M.Z.S., read a paper, in which he gave a
list of the birds he had collected during a recent ex-
pedition to Costa Rica. The number of birds col-
lected during his five months' stay was about one
thousand in number, representing two hundred and
fifty species, amongst which were two new to science
{Zonotriehia boucardi and Sapphironia boucardi of
Mulsant) and many others of great rarity.
" Sponsa's Headquarters." — I find I made two
mistakes in my article. They both occur in the list
of Diurni at the end of the article -.—Aglaja should
be omitted ; and, for Artaxerxes, of course Agestis
should be put. At the time I wrote the paper I was
much occupied with Artaxerxes, and suspect that was
the reason of the mistake. — Hastings C. Dent.
BOTANY,
The Inflorescence of Gourds. — The gratifica-
tion which I feel at the interest excited by my note on
the inflorescence of gourds and pumpkins is tempered
with regret at finding that I did not express myself
with sufficient clearness to be understood by your
correspondents, who seem to think that I had said
that fertile blossoms were expanded before any
staminate flowers had appeared on the same plant ;
HARD WICKE'S S CIENCE - GOSSIP.
65
■ which indeed was not my meaning. My observations
do not at all contradict those of Mr. Beal. What I
notice as remarkable is this: — In regular indefinite
inflorescence, when a flower appears in the axil of every
leaf, the flower in the axil of the lowest leaf is the
oldest, and therefore opens first ; then, that in the axil
of the leaf next above it ; and so on, as in the pimpernel.
In gourds and pumpkins, this order of expansion is
observed only among flowers of the same sex. Sup-
pose, then, that a plant bear ten flowers, the first
nine of them may be staminate flowers, the tenth,
pistillate. If a flower open every day, as is usual in
our climate, the fertile flower would not open in the
ordinary course till the tenth day. Instead of that,
however, it will be found expanded on the fifth and
sixth ; it may be simultaneously with one of the
staminate flowers or not, but always before the
staminate flower immediately below it. Flowers of
the two sexes, though indiscriminately mixed as to
position on the stem, thus form two series as to the
order of their expansion. I think that there are
usually more staminate flowers produced early in the
season, and a tendency afterwards to the production
of pistillate flowers which are abortive for want of
vigour in the plant to perfect them. I only remember
one instance of a gourd producing a fruit blossom too
early in the season to be fertilized : it was a miniature
gourd, which produced a fruit, as the result of that
blossom, with no seed. — John Gibbs, Chelmsford.
ASPLENIUM SEPTENTRIONALE AND GERMANI-
CUM. — About ten years ago I found Asplenium septen-
trionale in the Beddgelert district. There were a great
many plants growing within a limited area, but the
spot was very difficult of access, and it was, perhaps,
owing to this that they had escaped observation. I
brought away four or five specimens, and took fronds
from some other plants, but they were all septen-
trionale. I did not look specially for Germanicum,
certainly, but, as far as my observation went, there was
not a plant of it there. At the same time I quite
agree with the observer whose opinion Mr. T. Belt
quotes, that a very close relationship exists between
these two species. — Edward Hart Vinen, M.D.
Gentiana ACAULis. — In the Autumn of 1875, I
was staying, after illness, at the Freshwater Hotel,
Isle of Wight, and, during my first ramble over the
Downs, I gathered two species of Gentiana, which I
sent to my friend Mr. Varenne, of Kelvedon, who has
a fine collection of British plants, and is a first-rate
botanist. After reading the communication in your
last, about the appearance of Gentiana aeaulis in that
locality, I wrote to Mr. Varenne to let me know
what species I sent him, and I enclose his answer : —
"Dear Dr. Bree, I am much afraid the lady who wrote
in Science -Gossip made a mistake about the
Gentiana aeaulis in the Isle of Wight. You collected
two specimens of gentian there, in September, 1S75,
as forwarded to me. One was a stunted state of
Gentiana Amarella, and the other, equally dwarf, was
a specimen of Gentiana campestris, probably. Both
are many-flowered, and by that character very
different from Gentiana aeaulis. — E. G. Varenne.'" —
Dr. Bree.
Gentiana acaulis.— I would beg to remind your
correspondent, "J. C. M.," with reference to some
remarks inserted in your recent issue, that the flower-
ing of plants vastly depends upon elimatal influences.
There is no reason because G. acaulis blossoms on the
Swiss Alps towards the middle of June till July, that
therefore it should flower here at that time ; the con-
ditions are totally dissimilar. Many years ago I
noticed several blossoms of this lovely plant, in a
friend's garden in East Sussex, during the month of
September. It has been stated that " Alpine flowers
are signalized by the intensity of their colours, this
increase of brilliancy in tints being attributed to the
pure snow-water nourishing the roots, to the greater
excitement of the light, and refined purity of the air."
Not only so, there are other forces at work which
should cause an earlier floral development. They get
a longer and more persistent rest in winter, and pro-
tection from the carpet or blanket of snow. During
my travels in Italy, in February and March of 1865,
vegetation appeared to be most backward ; but on
my return home by Florence, in early April, the vege-
table world was in full luxuriance of leaf and beauty.
Whilst journeying over the Mont Cenis pass,
numerous flowers were in full bloom, some peeping
through patches of snow, others in places where it
had melted. Nothing of the kind existed out of doors
in England. If indeed G. acaulis blossoms with us
in June and July, as it is said to do on the Alps
during those months, the remarks by Treviranus,
quoted by Dr. Lindley in his "Theory and Practice
of Horticulture," might hold good: — "It is well
known that plants from the northern half of the
world, when they have become naturalized in the
south, have changed almost entirely the time of their
vegetating, blooming, and fruit-bearing, so as entirely
to accord with the habits of the indigenous plants of
the country. Thus we find at the Cape of Good
Hope oaks, alders, almond, peach, and apricot are
in full bloom in August." Our best botanists, such
as Mr. Bentham, I believe, maintain that G. acaulis is
not indigenous here ; so it might obey the dictum as
laid down by Treviranus. — John Colebrook.
Gentiana acaulis (S. G. 1878, p. 18). — I hope
your fair correspondent, Isabella H. Knox, will not
be offended if I tell her in your pages that Gentiana
acaulis is not found wild in the Isle of Wight, and.
that the plants she found between the Needles and
Freshwater were not Gentians at all, but dwarfed
specimens of Campanula glomerata. There can be
no doubt about it. Bromfield, in his "Flora Vic-
66
HARD WICKE 'S S CIENCE - G OS SIP.
tensis," says of the plant, "on Freshwater Downs in
various places, as near the Needles Plotel and Light-
house, but scarcely an inch high, being browsed
down by sheep " ; and he further adds in a note at
p. 291, "On the bleak and lofty Downs, at the
western extremity of the island, this species scarcely
attains an inch in height, and specimens from thence
were actually described and figured by Withering
("Arrangement of British Plants," 3rd ed. ii p. 282,
and pi. xi., fig. 5) as a new species of Gentian, and
named by him G. collina." I. H. K. may therefore
■console herself that others before her have been
deceived by the same plant at the same place. — Win.
Marshall, Ely.
Side Lights on the Composite. — A most
suggestive paper on this subject appears in the last
number of the Journal of Botany by Dr. Masters.
It is based on a specimen of Helenenium autumnale,
in which all the florets appeared stalked and bearing
opposite leaves on the stalks, the whole forming a
corymb of flowers instead of the ordinary capitulum
of a composite.
British Marine Alg/e — Mr. H. Goole (Ply-
mouth) desires us to correct a few mistakes which
appeared in his communication on the above subject
in our last issue, p. 40. For instance, instead of Dasya
puviicea it should be D. punkca ; for Dudrisinia
dudrisnagra there should have been Dudresnaia
dudresnao-ia.
GEOLOGY,
Important Paper on the Geology of West-
ern Scotland. — At a recent meeting of the
Geological Society of London, Prof. Judd, F. R.S.,
read a most important and highly interesting paper
on Scottish geology. During the seven years in which
he has been engaged in the study of these interesting
deposits, the author has been able to prove that not
only is the Jurassic system very completely repre-
sented in the Western Highlands, but that associated
with it are other deposits representing the
Carboniferous, Poikilitic (Permian and Trias) and
Cretaceous deposits, the existence of which in this
area had not hitherto been suspected ; and by piecing
together all the fragments of evidence, he is enabled
to show that they belong to a great series of forma-
tions, of which the total maximum thickness could
have been little, if anything, short of a mile. The
relations of the scattered patches of Mesozoic strata
to the older and newer formations respectively, are
of the most interesting and often startling character.
Sometimes the secondary rocks are found to have been
let down by faults, which have placed them, thousands
of feet below their original situations, in the midst of
more ancient masses of much harder character.
More usually they are found to be buried under many
hundreds, or even thousands, of feet of Tertiary lavas,
or are seen to have been caught up and enclosed
between great intrusive rock-masses belonging to the
same period as the superincumbent volcanic rocks.
Occasionally the only evidence which can be obtained
concerning them is derived from fragments originally
torn from the sides of Tertiary volcanic vents, and
now found buried in the ruined cinder-cones which
mark the sites of those vents. In some cases the
mineral characters of the strata have been greatly
altered, while their fossils have been occasionally
wholly obliterated by the action of these same igneous
forces during Tertiary times. In every case, the
survival to the present day of the patches of Secondary
rocks can be shown to be due to a combination of
most remarkable accidents ; and a study of the dis-
tribution of the fragments shows that the formations
to which they belong originally covered an area having
a length of 120 miles from N. to S., and a breadth
of 50 miles from E. to W. But it is impossible to
doubt the former continuity of these secondary
deposits of the Hebrides with those of Sutherland to
the north-east, with those of Antrim to the south,
and with those of England to the south-east. From
the present positions of the isolated fragments of the
Mesozoic rocks, and after a careful study of the
causes to which they have owed their escape from
total removal by denudation, the author concludes
that the greater portion of the British Islands must
have once been covered with thousands of feet of
secondary deposits. Hence it appears that an
enormous amount of denudation has gone on in the
Highlands during Tertiary times, and that the
present features of the area must have been, speaking
geologically, of comparatively recent production-
most of them, indeed, appearing to be referable to
the Pliocene epoch. The alternation of estuarine
with marine conditions, which had, on a former
occasion, been proved to constitute so marked a
feature in the Jurassic deposits of the Eastern
Highlands, is now shown to be almost equally striking
in the Western area ; and it is moreover pointed out
that the same evidence of the proximity of an old
shore-line is exhibited by the series of Cretaceous
strata in the West. Although the comparison and
correlation of the Secondary strata of the Highlands
with those of other areas, and the discussion of the
questions of ancient Physical Geography thereby
suggested, are reserved for the fourth and concluding
part of his memoir, Prof. Judd took the opportunity
of making reference to several problems on which
the phenomena now described appear to throw im-
portant light. In opposition to a recent speculation,
which would bring into actual continuity the present
bed of the Atlantic and the old Chalk strata of our
island, he points to the estuarine strata of the Hebrides,
as demonstrating the presence of land in that area
during the Cretaceous epoch. He also remarks on
the singular agreement of the conditions of deposition
HARD WICKE 'S S CIENCE - G OS SI P.
67
of both the Silurian and Cretaceous strata of the
Scottish Highlands and those of the North American
Continent. But he more especially insists on the
proofs, which we now have, that the Highlands of
Scotland, as well as the greater part of the remainder
of the British Islands, were once covered by great
deposits of Secondary strata, and that the area has
been subjected to enormous and oft-repeated denu-
dation. He dwells on the evidence of the vast
quantities of material which have been removed
subsequently to the Mesozoic and even to the Miocene
period, and he maintains the conclusion that many, if
not all, of the great surface-features of the Highlands
must have been produced during the very latest
division of the Tertiary epoch, namely the Pliocene.
The Fossil Fungus. — I have frequently observed
that, in being called upon to answer criticisms of my
work, I have more commonly to reply to statements
I have never made (or even thought of) than to defend
the position I have really taken. In your January
number (p. 21) P. Martin Duncan combats the idea
that Peronosporites "is perhaps the oldest fungus on
record. " I have never made any such statement, so
I need not reply. Your correspondent then quotes
instances of Algae being found in older rocks than the
Palaeozoic, but as my description refers to a fungus,
and not to an alga, the instances brought forward by
P. M. Duncan, though of the greatest value and in-
terest, refer rather to true algce than fungi, i.e., if the
distinguishing characters between the two, and now
generally received, are to hold good. The letter in
your February number (p. 41), signed "John Butter-
worth, Goats Shaw, Oldham," is of a very different
character, and hardly demands an answer. This
gentleman writes to "dispute " my " claim to its dis-
covery," because he " discovered " it {i.e., the Pero-
nosporites), and read a paper upon it (at Manchester)
which was not published. Now, I have never set
myself up as the "discoverer " of the fossil fungus ; I
claim to be nothing more than the humble drudge who
pored over the fungus preparation for some weeks,
made out the structure of the mycelium and fruit, its
affinity with living plants, and then attempted a de-
scription and illustration. If J. Butterworth did all
this in 1874-5, I regret, with him, that some per-
manent record was not made of his work " in some
leading journal." In my paper I distinctly stated
that Mr. W. Carruthers, F.R.S., the Keeper of the
Botanical Department of the British Museum, was
the "discoverer" of the plant, as he certainly was —
and something more. The parasite has been known
by this gentleman for many years. J. Butterworth
states that a member of his Society identified his
fungus "as Peronosporites" in 1874-5. How this
learned "member" did so, I am at a loss to know,
as no such genus as Peronosporites existed before last
year, when the name was given by me to the parasite
in question. I have certainly had something more
than a " casual " view of the slide, as I have had it in
my own house for six months, and have it now. —

The Fossil Fishes of Sussex. — At a recent
meeting of the Eastbourne Natural History Society,
Dr. Ward read a paper on ' ' The Fossil Fishes of the
District." They are met with chiefly in the Upper
and Lower Chalk strata of the Downs at Holiwell ;
others in the Greensand and Gault ; and a few in the
Wealden beds. Dr. Ward's paper was illustrated by
specimens.
NOTES AND QUERIES.
The Importation of Humble Bees into New
Zealand. — Perhaps some of your correspondents
could give some valuable hints as to the best method
of importing humble bees into New Zealand. The
farmers there are anxious to introduce them, as they
are said to be necessary for the successful cultivation
of clover, which they aid by carrying about the
pollen. An attempt was made, I understand, to
bring over a number of the insects, but they all died
an the way, and it has now been proposed to bring
over the eggs. But if, as I believe, the larvce are
hatched in cells, and fed by the parent bees until
entering the pupa-state, this idea would not seem to
promise better success than the former. Could the
perfect insects be transported in a torpid state ? Or
would it be possible to naturalize them by introducing
the pupa;? I hope some practical solution of the
auestion maybe given by some contributor. — Charles
B. Moffat.
Crayfish in Cumberland. — Some of the small
runners into Croglin Water, a tributary of the Eden,
abound with crayfish. I had many opportunities of
seeing them last spring. The inhabitants of the dis-
trict have a legend that the "crabfish" were intro-
! duced by some member of the Featherstonhaugh
j family, but so long ago that I could gather no precise
information as to the date. I think it improbable
that they are indigenous, but not knowing anything
of their geographical distribution, I shall be glad of
any information on the subject. — W. Duckivorth,
Grey-street, Carlisle.
Natterjack Toad on the Shores of the
Solway Firth. — -While staying at Bowness on
Sol way in August last, I found quite "a colony of the
Natterjack. On one part of the shore, where the
ground was damp, nearly every stone of moderate
size I turned up had a natterjack below, sometimes
two. There was no mistaking it, the yellow line
down the back being ample means of identification.
It would be interesting to know if ever it has occurred
thus far north before, as I was under the impression
that it belonged only to the east and south of Eng-
land.— IV. Duckworth, Grey-street, Carlisle.
The Pigeon a Polygamist. — In Mr. Dixon's
interesting account of the pairing instinct of birds,
; he says, ' ' I have once observed the rook practising
polygamous propensities. We have a pigeon of the
' horseman ' variety which is a confirmed polygamist.
I observed this during the course of last summer
repeatedly." Is this peculiarity in the pigeon known
to ornithologists as a common or uncommon occur-
rence ? Does this present to view an inherited energy,
or only applicable to the surrounding circumstances ?

HARD JVI CKE ' S S CI EN CE-GO SSI P.
Query respecting Sea-Anemones. — Sea-
Anemones, like other animals, require to " be
fed." But, unlike most other domestic animals,
this need not be done daily. Once a week will
do in most cases, though some like it oftener ;
but if it fouls the water more harm than good will
accrue to the animals by over-feeding. No doubt
they derive some nourishment from organisms in the
water, but these should be microscopical, and not
perceptible, i. e., the water should even be sparMingly
clear and colourless ; if not, there is something wrong.
Find out the cause of this, and set it right without
changing it : time and patience alone will often
effect this. Or it may be aerated or circulated with-
out changing. In no case change it, unless it has
become chemically poisonous. Organic impurities
can always be got rid of by oxygenation, or a process
known as cremacausis, or burning up. Thus, living
animals give out carbonic acid gas, and certain effects
of food, which, if allowed to accumulate, generate
carburetted or sulphuretted hydrogen. But living
plants take up these poisonous gases (assimilate the
carbon to build up their tissues), thereby rendering
them harmless, and liberate the free oxygen again for
the animals to breathe. This goes on ceaselessly
under the action of light, and this balance of animal
and vegetable life is the grand governing principle of
all aquaria, great or small. If W. T. If. C. Trome
wishes to keep a scientific aquarium, he will remember
this, and never change the -water. He will thus be
able to keep his animals more happily, healthily, and
easily. But the anemones must be fed. Mussel or
oyster flesh is best, handed to each individual by a
pair of wooden forceps, in pieces varying in size from
a pin's head upwards, say, to a quarter of a mussel,
according to the size of the anemone ; experience
will soon show how much. Under proper conditions
this is nearly all assimilated. If it is rejected, perhaps
the pieces are too large, or the water too hot or too
cold, or the animals too crowded, — most probably
the latter with beginners. The thing is to find out
how many animals will live and flourish in a given
space : keep these and no more. If oysters or mussels
or fish cannot be easily procured for food, butcher's
meat will do, but not so well. Much depends upon
the distribution of the water. The smaller the
depth in proportion to the size of the animals the
better; because the greater the surface aeration,
and, as oxygen is perpetually wanted for the animals
to breathe, and to purify the water, the more regular
the supply the better. This may be accelerated by
stirring in air, say, with the stick of a camel's
hair pencil, this may be done daily, especially so
the day after feeding, to prevent or dissipate any
cloudiness in the water. The brush at the other end
will be useful to pick up any refuse bits, and skim off
the mucus which otherwise collects round the base of
most anemones, and would in a state of nature be
washed away and dissipated by the waves. We
collect them into a cup of water, and throw them
away, and thus prevent the accumulation of untidi-
ness, in small domestic aquaria of still water. In
large aquaria, as at the Crystal Palace, impurities are
dissipated by a ceaseless flow of water from tank to
tank, down to the underground reservoir, to be
pumped up again fresh and clear for ever ; and I
know of no cheaper or better guide than the sixpenny
and twopenny handbook to this successful institution ;
but if \V. T. H. C. Trome will state his aquarium
dimensions and difficulties, we may be able to tell
him more in Science Gossip. Hardy anemones
are about the easiest animals to begin with. Ours
live and flourish, year after year, in shallow tanks, or
glasses, commercially known as "anemone pans,"
or pastry pans. In all cases growing plants cannot
be dispensed with, and spontaneous vegetation is found
best, because best suited to each separate situation.
To prevent this growing to excess, and causing the
water to become green, avoid too much direct day-
light, by using blinds or screens. Blue paper will
sometimes serve sufficiently. — G. S.
Botanical Localities. — The following is a fairly
accurate description of the localities inquired for by
Mr. H. Morton, in the January number of Science
Gossip : — Shotover Hill is z\ miles E. of Oxford ;
Cowley is a village not far from the latter place,
2 miles S.E. of Oxford ; Bagley Wood lies 2.\ miles
to the S. of Oxford and 3 N. of Abingdon; Wych-
wood Forest (Winch wood being apparently a mis-
print) lies 14 or 15 miles to the N.W. of Oxford
(nearest station, Charlbury, on the Oxford and
Worcester line) ; Cornbury Park is situated at the
N.E. corner of Wychwood Forest, and half a mile S.
of Charlbury station. I have been unable to discover
the exact situation of Cornbury Quarry, but presume
it must be in the immediate neighbourhood of the
Park. Sunninghill Wells is in the extreme S.E.
corner of Berks., 6 miles S.S.W. of Windsor, 6W. of
Egham, *j\ E. of Wokingham, and nearly a mile from
Ascot station. Most of these places are, as Mr.
Morton says, good localities for plants (I knownothing
about insects), and he may perhaps be interested to
know what plants may be found there. The fol-
lowing are the names of a few, which I give partly
from my own observation, partly from " Walker's
Oxfordshire Flora." Shotover Hill, Polcmonium
cceruleum, Droscra rotundifolia, Gentiana Amarella,
G. campestris, Trifolium subterraneu?n, Haboiaria
bi folia, H. viridis, Epipactis palustris, Cephalanthera
grandijlora ; Cowley, Geranium rotundifolia, Pin-
guicula vulgaris, Anagallis cczrulca, A. tenella, Fri-
tillaria mcleagris, Orchis conopsea ; Cowley Bog is
also very rich in Scirpi, Carices, &c. ; Bagley Wood,
Irisfastidissima, Convallaria viajalis, Luzula congesta,
Neottia nidus-avis ; Wychwood Forest, Asperula cy-
nanchica, Atropa Belladonna, Orchis pyramidalis.
If Mr. Morton wishes to learn more about the good
botanical localities in this neighbourhood, I shall be
very happy to correspond with him. — H. IV. Trott,
24, Walton-street, Oxford.
Entomological and Botanical Localities.
— (Reply to H. Morton.) (Winchwood should be
Wychwood ; Sunninghill Wells should be Sunning-
well Hill. ) Four of the places inquired for are within
a short distance of Oxford — say two to four miles
Shotover and Cowley are on the Oxfordshire side of
the Thames valley ; Sunningwell and Bagley Wood
on the Berkshire side. Shotover may be reached by
rail to Wheatley, whence a pleasant walk of five
miles over the hill to Oxford. Sunningwell and
Bagley form part of an ironsand range of hills bound-
ing the Thames valley, between Abingdon and
Oxford, and are easily accessible from Radley sta-
tion. Cornbury Park and Wychwood Forest adjoin
Charlbury station on the West Midland line, about
twenty minutes' ride per rail from Oxford. — E. C.
Davey, JVantage.
FAIRY Flax (No. 15S, p. 44), and Fairy Lint,
are names which, according to Johnston, in his
" Botany of the Eastern Borders," are given in the
border-land to Linum ca/harticum, L. The district
comprehends "Berwickshire, the Liberties of Ber-
wick, N. Durham, and the immediately adjacent
parts of Northumberland and Roxburghshire." I
should think the name, " Fairy Flax," is given to this
HARDWICKE'S SCIENCE-GOSSIP.

pretty little plant merely from its delicate appear-
ance, being, in fact, a miniature or fairy imitation of
the common flax in everything but the colour of the
flowers. Still there may be some legend connecting
it with the fairies, and, if so, I shall be much obliged
to any correspondent who can furnish me with any
folklore of Fairy Flax illustrative of its name or other-
wise. " E. L. S. "may be interested to know its other
English names, though, as far as I am aware, it has
fewer than most British plants. Gerard calls it
Mill Mountains, which Prior, in his " Popular Names
of British Plants," derives from the Lat. Cha-moel-
inum montanum, Gr. , xcrjuat-Xtvov, Ground-Flax.
In Cumberland, Shropshire, and Cheshire it is called
Mountain Flax, being frequent in hilly and moun-
tainous districts : and in the latter county it is also
known as Purging Flax, a translation of its scien-
tific name, or vice versa, and it is so called from its
reputed cathartic properties. In Cheshire, however,
I have found that herb-doctors are not very particular
what the effects of a herb may be, so long as it is a
herb, and they generally administer it as a stomachic
on account of its bitter taste. — Robert Holland.
The Nebular Theory. — It has been discovered
by M. Cailletet, and M. Raoul Pictet that our air can
produce water; they have also converted oxygen and
nitrogen into liquids, and have produced a vapoury
cloud from hydrogen, under great pressure and ex-
cessive cold. Under the nebularh ypothesis of La-
place, the origin of water is nowhere satisfactorily
accounted for. Mr. Proctor has told us that it is to
all intents and purposes demonstrated that the nucleus
of this earth was formed from a nebulous condition.
The German astronomer, Gruithuisen, adopting the
same primary condition, formed this earth by the slow
aggregation of cold matter, leaving the water origin
unaccounted for. By this new discovery, it seems
that all the conditions for producing the water were
present under the latter system. The light and heat
had not penetrated the nebula ; there was therefore
intense cold, as there is now in the air above us and
at the sea-bottom. As the solids of the nebula slowly
condensed, they caused great pressure. As the gases
are expressed now in water from the earth, so we may
infer that they were at the beginning. In The Mail
of January 9th, 1878, I find, "It is only a question of
carrying these experiments further in order to reduce
these liquid gases to the solid form." We have then
a nebulous mass filling the whole space now occupied
by the atmosphere, the water, and the solid earth.
Under the universal law of gravitation, the heaviest
molecules of the mass subsided towards their centre —
as these molecules condensed, they produced pressure.
Hence we have the result in our quasi-solid earth, the
water resting on it, and the air enveloping the whole,
the entire system resulting naturally from the nebu-
lous mass, the sunlight and heat reducing or refining
the atmosphere to its present condition by causes well
known. — H. P. Malet, 8, Via Venezia, Florence.
Harebell (No. 158, p. 47). — There are two good
reasons why this name should not be derived from the
hairlike stalks upon which the flowers hang. The
first is that the spelling " Hairbell " is of compara-
tively modern introduction, inasmuch as the older
writers, such as Gerard and Parkinson, spelled it
" Harebell," though it must be confessed that the
spelling of the older herbalists does not go for very
much. The second reason is that when those old
writers do make use of the name, they are not speak-
ing of Campanula rotundifolia, but of Scilla nutans.
When the name was transferred in books from Scilla
to Campanula I am not aware. Some choose to spell
the word "Airbell," from the supposition that it
refers to the colour of the flowers being similar to the
air or sky ; but the same objections apply to this also
— the first does, at any rate. As a matter of fact,
however, the name Harebell or Hairbell is not the
name in most general use, except in books, for either
plant. In fourteen different stations in England and
Scotland I only have Hare — or Hairbell recorded for
Campanula in three, viz , Yorkshire, Cheshire, and
the West of England ; and in twenty-five counties I
have the name applied to Scilla in but one, Devon-
shire. Lyte is, I think, the oldest writer who gives
an English name to C. rotundifolia, and he calls it
"Blewbelles," which is still one of its commoner
names, but which is also as often given to Scilla. It
would seem, then, that Scilla nutans is the original
"Harebell"; that it was "hare," not "hair"; that
the name has been transferred to Campanula rotundi-
folia, and the spelling altered in some cases in order
to account for the name, because its stalks are delicate
and hairlike. I do not possess a copy of Gerard to
refer to, but it is possible he may say why Scilla is
called " Harebell."— Robert Holland.
Pairing Instinct of Birds. — As to the question
of birds using the nests of other species, and why not
of the same species? It will invariably be found that
the selected nests are old ones, and belong to birds
who only once use them for their purpose. In the
case of the House Sparrow using the nest of the
Martin, the bird has utilized it for its purpose, in the
absence of the Martins, and, upon their return, keeps
possession of the nest by "force of arms," and 'con-
sequently compels the rightful owners to build else-
where. I may also mention that sparrows may be
found breeding the year throughout, and retain their
old nests in many, if not all cases. There is a stately
fir-tree in my neighbourhood containing several
sparrows' nests. They have been there for several
years, and I have not the least doubt but they have
been tenanted by the same pairs of birds, as the nests
are always equal in numbers, and should one of the
nests be destroyed, it will again be built in a more
inaccessible situation. Now, if birds used the nests
of their own species indiscriminately, their ranks
would be fraught with strife and discord, which I
have, as yet, failed to observe. All birds would con-
sequently strive to obtain an old nest, rather than be
at the trouble of constructing one for themselves ;
fierce combats would prevail, and then, no doubt,
the " survival of the fittest " would in one sense be
correct. Again, all birds work as influenced by their
respective instincts. The Martin, having once con-
structed its abode, remains, through the agency of
instinct, at rest, as far as nest-building is concerned,
until that structure is damaged, or forcibly taken from
it, as in the case of the sparrow, when it must repair
its handiwork, or make new quarters elsewhere, if
not able to repel the aggressor. How can we explain,
except through this peculiar instinct, the annual
return of the same number of birds, and the little
wanderers alighting upon their temporary homes
shortly after their arrival; or, if their nests have been
destroyed, clinging to the old sites, and, as the breed-
ing season arrives, constructing new nests on the ruins
of the old ones? A word as to the circumstance
mentioned by your correspondent, "G. T. B." Ihave
no doubt that he is quite correct in believing that
the pair of blackbirds laying in the same nest
three successive years is one and the same pair.
But did not the nest undergo repairs? I have
never known a nest of this bird, however com-
pactly built, be fit for its purpose again, even the
next season, let alone three successive seasons.
7°
HA R D J VI CKE 'S S CI EN CE-GO SSI P.
However, as no such instance has come under my
own observation, I decline making further remarks
■on such instance. The blackbird pairing with the
song-thrush, if correct, is no doubt a very exceptional
occurrence, and can only be explained as a mon-
strosity, which this, and all similar instances, un-
doubtedly are, and which, however unexplainable,
are repeatedly found in various birds and animals.
I will also mention the fact, that the pairing of
annual birds is not so closely linked with the vernal
year as is currently supposed. The hedge-sparrow,
through what I have observed, invariably pairs late
in December. A few weeks prior to that date the
birds are solitary; they gradually become more social,
and very garrulous ; and now, at the time of writing
this, all specimens seen are invariably in pairs. I
think Mr. Parsons somewhat mistakes my object in
saying, "the only way is by polygamy." I do not
for a moment entertain the idea that all birds could
multiply quickly by practising it, but only those
which I have stated (first section of gallinaceous
birds), and for what that gentleman brought forward
the human race as examples, bearing on the present
subject, I am at a loss to imagine. As to polygamy
occurring ill species under domestication, I ask why
the domestic swan (C. olor) remains in a strictly
monogamous state for life, although, in mafiy cases,
the males must be in the minority. I have known
a case where three of these birds were kept (two
females and one male). Now, the male bird paired
with one of the females and remained united to her,
and never bestowed any of his affections upon the
more unfortunate female. Ducks always show a
polygamous instinct when in confinement, if the
females do not exceed the males. Again, the do-
mestic pigeon, though the females may far exceed
the males, a polygamous instinct will never be
manifested, the male birds pairing in due season,
and assisting to rear their offspring with as much
care as the female birds. It must also be remem-
bered that the males of polygamous birds are in-
variably of bright, if not conspicuous colours, while
the females closely resemble the colours of surround-
ing objects. The males, too, are the best eating,
invariably the largest, and consequently the most
liable to capture, and the most prized as articles of
food ; while the females are more often rejected, or
never discovered in their haunts. It will thus be
seen that the females would exceed the males, and,
did no such polygamous instinct exist within them,
circumstances the most disastrous would arise with
deadly certainty to their race. Thus, I again say,
that through one of the wisest provisions of nature,
these birds are able to afford us sustenance, and at
the same time maintain their position amongst their
•congeners in the struggle for existence. — Charles
Dixon, Hecley, near Sheffield.
The Pairing Instincts of Birds. — Seeing
something in January part of Science-Gossip, about
the pairing instinct of birds, I thought the following
might be interesting. About April of last year I had
a brood of chickens, and amongst them I reared one
duck. When they grew old enough I killed all the
cocks except one, for which one the duck has shown
a strange attachment, following it all about. The
cock has reciprocated and continued this sexual
attachment, showing a decided preference for the
duck over the hens. I have, unfortunately, lost the
duck, but the night before, the cock, instead of going
up to roost beside the hens, as it generally did, slept
on the ground beside the duck. It is impossible now
to say what would have been the result of their
attachment ; but perhaps some of your readers would
say whether they have observed the like. — John
Baillie, Sunderland.
Herrings. — Can any of your numerous readers
inform me, what are the signs by which some fisher-
men know where large bodies of herrings are
swimming, even when their boats are sailing rapidly
through the water ? — J. W.
Dredging. — Would some of your correspondents
be so kind as to give me some information on dredging
not far from the shore, also as to what books would
be useful in determining the objects I am likely to
find?— R.G.C.
Curious Modes of Blossoming. — I have in my
garden here a Rhododendron which grows near the
house, and is sheltered by it from the south and
west, but has no shelter from the north or east. For
the last three years it has blossomed about this time
of the year (January). There have been several flowers
this year, but all on the same side of the tree, and
near together. Last year they were on the other side,
towards the house, and were a little earlier (at Christ-
mas), and less numerous, but this year there is no
shelter whatever from the north and east. The
flowers are a beautiful pink, like the flowers on the
same tree in the summer. There is also a yellow
jasmine, which grows in the drawing-room balcony,
now in blossom, and neither of these plants has any
sun during the winter, and not much in the summer,
owing to their position. — L. T.
Caves in Somersetshire. — Nearly all that is
known of these caves is summarised in Mr. H. B.
Woodward's "Memoir on the Geology of East Somer-
set, and the Bristol Coalfield," published in 1S76
by the Geological Survey ; but as ' ' Somersaeta " and
other readers of Science-Gossip may not have ac-
cess to such expensive luxuries as Survey Memoirs, I
venture to offer a brief epitome of the subject. The
Lamb Cavern near East Harptree is now closed. It
seems to have been artificial, but was fully described
in Collinson's "History of Somerset" (1711). In
Burrington Combe are several caverns, four of which,
viz., Aveline's Hole, Plumley's Den, Whitcombe's
Hole, and the Great Goatchurch Cavern in Lower
Twinbrook Ravine, were explored by Professor Boyd
Dawkins and Mr. W. A. Sandford. (Geol. Mag.
vol. ii. p. 43 ; Rep. Brit. Assoc, 1864 ; Proc Somer-
set Arch, and Nat. Hist. Soc, partii., vol. xii. p. 161.)
They obtained remains of sheep, ox, reindeer, roe-
deer, ibex, goat, mammoth, bear, water-vole, wolf,
fox, badger, rabbit, hare, pig, mole, birds, and, in
Aveline's and Whitcombe's Holes, of man. The
human bones encrusted with stalagmite were evidently
buried. There are, or were, also caves in the Carboni-
ferous Limestone at Weston-super-Mare, Loxton, the
western end of Banwell Hill, and near Hutton. At
Uphill there are caves in the same formation, in which
remains of mammoth, deer, rhinoceros, wolf, ox,
horse, bear, otter, pig, hycena, fox, polecat, water-
vole, mouse, birds, and man, have been found.
(Pooley, Geologist, vol. vi. p. 331 ; E. C. H. Day,
Geol. Mag., vol. iii. p. 118 ; W. W. Stoddart, Proc.
Bristol Nat. Soc, vol. v. p. 37.) There are several
caverns at Cheddar, but Cox's is, though not large,
perhaps the most beautiful in England from its stalac-
tites. Bones of bear, deer, ox, horse, and man,
were recorded from a cave on the summit of the
Mendips here, by Mr. Long, in 1838. (Brit. Assoc.
Rep. 1838, p. 85.) Wookey Hole, near Wells, more
correctly spelt Okey (from British ago, a cave), is only
second to the Peak Cavern in Derbyshire in point of
size, being nearly six hundred feet long, and, in one

part, eighty feet high. It is in the Dolomitic Con-
glomerate of the Trias. Messrs. Dawkins and Sand-
ford found here bones of hyaena, lion, bear, wolf,
fox, mammoth, two species of rhinoceros, horse,
Irish deer, red deer and reindeer, and human im-
plements of flint, chert, and bone, of contemporary
date. (Dawkins, Q. J. G. S., vol. xviii. p. 115;
vol. xix. p. 260 , Proc. Somerset Arch, and Nat.

Mag., vol. ii. p. 44.) — G. S. Bonlger.
The Furniture Beetle. — I can mention another
instance of destruction to furniture by the " furniture-
beetle." Two years ago I found them working and
living in the frame of a sofa that has been about thirty
years in my possession. The sofa was taken out of
the house, and during three days was frequently
brushed with very strong carbolic acid. Last week I
examined it, and found fresh borings of this pest.
The sofa has a beechwood frame, 1 in. thick and faced
with mahogany half-inch thick. The insects have not
touched the mahogany, but in many places have bored
close up to it. I am now having the beechwood re-
moved, and mahogany substituted. Can anything be
devised (short of destroying the wood) that would kill
these destructive insects ? I fear that their habits
render liquid applications unable to touch them or
their eggs. — T. Hughes.
The Freshwater Aquarium. — Scarcely a
number of Science-Gossip appears but contains
queries or notes on the above subject ; and, judging
from some of these queries and the replies to them,
aquarium-keeping on a small scale would appear to
the tyro an extremely difficult task. We are told
(" Ben Plant," July, 1877) to limit the plants to three
species, molluscs to two, and reptiles to exclude en-
tirely. Others have complained of sticklebacks eating
all their snails, and of killing each other. My own
opinion is that there is nothing in connection with
practical natural history involving less trouble than
aquarium-keeping. In giving this opinion, it is true
that it is not the result of so many years' experience
as some of your correspondents can boast, but it is
based upon seven or eight years' successful work.
With regard to the vessel which is to constitute the
aquarium, I believe this to be of minor importance,
and that, so far as the inhabitants are concerned, a
washing-tub will serve as well as an elaborately con-
structed plate-glass tank, though, of course, the latter
is the best adapted for observation. I think the chief
charm (and use also) of an aquarium lies in the fact
that we see various creatures living under natural
conditions. To make the conditions as natural as
possible, I would introduce most of the inhabitants of
an ordinary pond ; the exceptions would be only such
species as prey inordinately upon the others. Such,
as the aquatic coleoptera and hemiptera, and the
larvae of dragon-flies. I would admit all the pond
gasteropods ; the two species of newts {cristalus and
punctatus), and I certainly have not found it necessary
to limit the species of plants. The larvae of the
caddis-flies are interesting and amusing, and I cer-
tainly cannot agree with " S. " as to the difficulty of
rearing them to their final stage. The aquarium must
have walls, and as the caddis-worms have legs, they
can therefore have no difficulty in reaching the surface.
It is no uncommon thing, at the proper season, to see
several escaped caddis-flies hovering about my aqua-
rium. "P. E. C." is troubled because the stickle-
backs eat his snails. His best plan would be to feed
the fish with small worms, until the snails have had
time to increase in number ; this they will soon do at
such a rate as will defy the most voracious stickleback.
Difficulties of this kind only occur at starting ; things
soon right themselves, and the ' ' balance of power "
is maintained. " S." thinks sticklebacks are the most
troublesome inmates of an aquarium. I would sub-
stitute " interesting " in place of "troublesome," and
I think Mr. Scott (Jan., 1878) has given " S." the
correct reason of his failure in keeping them. I believe
that all these difficulties are caused by having the in-
mates unnaturally select. With a plentiful and varied
supply of vegetation, a host of Entomostraca and In-
fusoria will be introduced, which will form an inex-
haustible food supply to the fish. The decaying plants
and animal exuviae will form a fine mud at the bottom,
in which the pretty little bivalve, Cyclas cornea,
annelids, &c, will find a congenial home. The water
should not be changed or disturbed. In spite of the
mud the water will neither be turbid nor odorous, and
the student can observe the habits of the inmates under
natural conditions. An aquarium, so conducted, may
not look so ornamental as an elegant glass vase with
a floor of scrupulously clean gravel, above which two
or three lazy gold-fish are slowly swimming round a
solitary plant ; but it will afford the microscopist or
biologist excellent opportunities of study. — Edward
Step.

HARDWICKE'S SCIENCE-GOSSIP.
H. Haines.— Your shells are all correctly named, and many
of them are most excellent examples of their kind.
G. A. Holt.— The object on Briza media was not a fungus,
but looks like one of the pollen masses of an orchid, transferred
by some insect.
J. Tempeke. — The micro-fungus on leaf of Lavatera
sylvestris is Puccinia malvacearunt, Corda.

No I. Pleurosigma ; 2. Stephanodiscus ; 3. Amphora avails;
4. is not a diatom ; 5. Globigerina is an interloper. It certainly
did not live with the diatoms, which are all fresh-water forms.
J. Cunnack.— Masters's " Vegetable Teratology ' was pub-
lished by the Rav Society.
A. B. C.—Marchantia should be pronounced Markantia.

REPORT OF SCIENCE-GOSSIP BOTANICAL
EXCHANGE CLUB,
N approaching this sub-
ject it is pleasant to say
we have in a measure
succeeded beyond our
expectations, but we
should have been still
more successful and
have been able to send
more of the marked
desiderata, had we been
supported in our efforts
by more of our working or rather collecting botanists.
Evidently it was regarded solely as an Amateur Club,
so that one of the rules seemed to be totally over-
looked in so far that a lot of specimens were sent
such as Bellis, Leontodon ; in fact, some few parcels
contained only such as could be gathered in a field a
few yards from our door. Another year, we are
satisfied, all this will be changed for the better.
A few contributors have kindly sent short notes
upon any specimens thought 'to be unusually rare :
these we give below. We also name a few good
things which we have had great pleasure in distri-
buting : — Ranunculus floribundus, Bab., common
in the Tweed district. Some of our plants ap-
proach elongaius, others triphyllus, and confusus. —
A. B. Ranunculus salsuginosus. This form is
frequent in the river Tweed. — -A. B. Ranunculus
fluitans, Newb., river Lathkill, Derbyshire. — C. B.
Draba niuralis, plentiful in cultivated ground
(nurseries), to which it has been introduced about
Kelso and Melrose, Roxburgh. — A. B. Raphanus
maritimus, Lizard Point, Cornwall. We supplied
about one half of the parcels with this rare species.
Dentaria bulbifera, High Wycombe. — T. E. D.
Viola Curtisii, Lytham. — J. C. M. V. amcena,
Bishop Auckland. — J. P. S. V. lactea, Helston,
Cornwall. — J. C. V. Curtisii, Land's End. — J. C.
Silene quinquevulnera. Introduced to the Tweed
district. — A. B. Cirava alpina, /3. intermedia,
Gaitheugh, Berwickshire, where it is abundant : along
with it I observed a few patches of C. luletiana,
No. 1 60.
possibly true " or typical." Alpina grows there also,
but I did not detect it. — A. B. Rubus ccesius, var.
pscudo-idtcus, Springwood Park, Roxburgh. Various
forms of Rubus ccesius are plentiful in the district, but
I have seen this only from the above locality. — A. B.
Rosa pomifera. On the roadside at the highest part,
above Sweethope, Roxburgh : one of the bushes is a
fine old plant about 7 feet high, and as much through .
They are as far as possible, under the circumstances,
from any house or garden, being about halfway
between two farm- places. I have never seen it in a
garden in the district. — A. B. Rosa Watsoni, also
common in the Tweed district, and, like Rosa subcris-
tata, very variable. — A. B. Rosa subcristata. This
variety is common in the Borders. — A. B. The
fruit of Watsoni can scarcely be confounded with any
other species, when once recognized. Alchemilla
conjuncta, Buttermere Fells, Cumberland. — R. W.
Upon writing to Mr. W. respecting this locality,
which is open to doubt, he informed us the specimen
sent was cultivated in his garden, but was originally
brought from Buttermere by a friend of his in the
North of England. Not the least doubt, however,
exists as to its being the true conjuncta, and if the
locality is also a genuine one, it is one of the most
important discoveries our contributors have brought to
light this season. We may also add, the leaves are at
least one-third larger than the plants we have inspected
at Kew and Benthall Hall. Mcdicago lappacea. I
have found a few specimens of this species on Tweed -
side every year, for the past five seasons. It grow^
in company with the other Medics (M. denliculala,
M. maculata, and M. minima), along with which it
has been introduced to the district with-wool. — A. B.
Trifolium Molinierii, Lizard Point. — J. C. T. stric-
tu?n, Lizard Point. — J. C. The above clovers are
old friends. It is pleasing to know they still retain
possession of the old station, from which they were
recorded many years ago. Sarothamnus prostratits,
Lizard Point. — J. C. Helianthemum caniun, Great
Orme's Head. — C. B. Ribes alpinum, Rokeby,
Teesdale. — J. P. S. Spergularia marginata, Arnside.

HA R D WI CKE 'S S CIE NCE-GO SSI P.
— C. B. Callitriche autumnalis, abundant in Yet-
holm Lock, Roxburgh. Although it has not been
recorded, so far as I am aware, from the Till or the
Tweed, judging from the large quantity that is
annually, after every high wind, carried into the Bow-
mont, and thence to the Till and the lower reaches
of the Tweed, it will very probably be found
there also. — A. B. We believe this was recorded
by Dr. Johnstone several years since. Lamium
intermedium, a rare weed in cultivated ground about
Kelso. — A. B. Scrophularia Scorodonia, Penzance.
— J. C. Pulmonaria officinalis, some very large
patches in Makerstown Woods, Roxburgh. Pro-
bably a remnant of monkish cultivation.— A. B.
Veronica peregrina, a garden weed, at New Louden,
Berwickshire. — A. B. This plant is rapidly spread-
ing : it seems but a few years since it was named
by Prof. Babington, from specimens then discovered
near Perth. Rumex rupestris, Helston. — J. C.
Polygonum littorale, Link, P. Rail, both gathered at
St. Bees Head. — C. B. P. arenastrum, Bor.,
St. Bees Head. — C. B. Orobanche azrulea, St. Owen's
Bay, Jersey. — G. C. D. O. rubra, Gunwalloe. —
J. C. Allium triquetrum, Helston. — J. C. Goodyera
repens, Bowmont Forest, Roxburgh. — A. B.
Plentiful in many Scotch Fir woods in both
Roxburgh and Berwickshire. Most likely it will
also be found in similar situations in Northumber-
land ; indeed, I have found it within three miles of
the borders of that county. Owing to the increase of
plantations, this plant has increased rapidly of late in
this district. The Goodyera appears to have been
one of the original natives of the Borders when this
part of the country was covered with forest. When
the land was cleared, it, and others of a like nature,
would disappear and remain in a dormant state, until
circumstances rendered the soil again suitable for
their existence. Cephalanthera gra?idiflora, High
Wycombe. — Mrs. T. E. D. Erica tetralici-ciliaris
Penryn, Cornwall. —J. C. Cuscuta epithynuun,
Kingswood-heath, Surrey. — J. L. Crocus nudiflorus,
Derby. — W. H. P. Impatiens parviflora, Ockbrook,
Derby. — W. H. P. Potamogeton nitens, Web.
Abundant in the Tweed and Teviot, in the counties
of Roxburgh, Berwick, and Northumberland (Che-
viotland). Like others of the genus, it is variable.
The description of P. nitens in " Student's Flora "
says the leaves are recurved, — surely a misprint for
incurved. — A. B. Potamogeto?i zoster a: folms, Spon-
don, Derbyshire. — W. H. P. P. lanceolatus, River
Lligway, Anglesea. — C. B. This is another record
for a very old station, originally made public in
Davie's "Welsh Botanology. " Plantago Timbalii,
Mullion, Cornwall. — J. C. We believe this has
not hitherto been noticed in the above county.
Veronica triphylla, York. — H. R. M. Mellittis
mellissophyllum, Beeralston, Devon. — W. H. Carex
humilis, Leigh Woods. — W. G. C. filiformis, abun-
dant in Lurgie Loch, Berwick ; Prins-de-bog, Rox-
burgh ; and Campfield Bog, Northumberland. — -
A. B. Wherever this species is met with, it is
generally abundant ; such is our limited experience.
C. digitata, near Tintern Abbey, Monmouthshire. —
C. B. — C. ornithopoda, Cresbrook Dale, Derbyshire.
— C. B. Three of our contributors send a limited
supply of the above novelty. It will doubtless be
new to most of the members. Carex punctata, Gau-
din. Ledges of perpendicular rocks in the Water-
winch, Tenby. — C. B. We hope again shortly to
refer to this species ; the fruits have been submitted
to Dr. Syme. Cyperus longus, Rennoch Valley. —
J. C. y uncus pygmceus, Lizard Down. — J. C. We
are glad to be able to supply the whole of the mem-
bers with this species, which is, comparatively
speaking, a recent addition to the British Flora.
Scirpus parvulus, mouth of Ovoca, Arklow. — C. B.
Kobresia caricina, Widdy Bank, Teesdale. — J. P. S.
Leersia oryzoides, Woking, Surrey. — H. E. W. It is
but seldom good specimens of the Leersia can be
secured ; nearly all we have seen have been im-
perfect : the few we have on this occasion distributed
are excellent examples. Bromus Lloydianus, near
Lizard Point. — J. C. Ophioglossum ambiguum, St.
Martin's, Scilly Isles. — J. C.
A total of forty-four parcels of plants were sent
out. In each case we made as good selection as was
within our power.
DOES DESICCATION KILL DIATOMS?
A COMMUNICATION on the above subject, by
M. P. Petit, was made to the Societe de
Botanique, Paris, and as the subject is of considerable
interest to the diatomist, we have much pleasure in
reproducing it.
" As the heat of summer dries up the ditches, pools,
and puddles, one sees that when the last trace of
humidity vanishes, the diatoms with which they
were stocked also disappear. But when the rains of
autumn and winter refill the places we have indicated,
the diatoms revive and soon reappear in great
numbers.
For some years I have gathered with care the
dried surfaces of the ditches in which I knew that
great quantities of diatoms existed, in the hope of
finding traces of spores or zygospores. I, however,
never found anything but empty frustules mixed
with the soil that had served as a substratum. Never
being able to find traces of spores, the idea occurred
to me to make experiments on the diatoms when
placed under the same conditions as occur in nature.
I therefore collected, at divers periods of the year,
the diatoms, with their substratum of mud or clay,
and submitted them to desiccation in the sun, placing
the material in glass vessels covered, to keep them
from dust, some for six, and others for eight months.
The desiccation was such that the deposits at the

bottom of the vessels were cracked in eveiy direction.
In the month of September last (1877) I examined
some fragments of these deposits. I saw that the
frustules were there, and also that they were trans-
parent and apparently empty. But on making a
more careful examination, I saw in the interior of
one of the extremities, in a majority of frustules, some
brown granules, which I considered were the remains
of the dried endochrome.
The vessels were then filled with distilled water
sufficiently aerated by prolonged agitation ; after this
they were exposed to the direct heat and light of the
sun.
During the first two or three days there appeared
but little change in the frustules, but on the fourth
day the large brown granules had augmented in size,
and had taken the yellow tint characteristic of the
diatomaceous endochrome. In following from day to
day the augmentation of the plasma, I remarked
that on or about the fifth day this nearly filled the
middle of the frustule, and on the eighth day it had
assumed the normal form peculiar to the genus to
which the species belonged. The naviculas had re-
sumed their curious movements, and some days later
it became evident that a number of the frustules had
commenced to multiply by self-division.
In the presence of these observations, we are able
to conclude that the diatoms, like many other of the
lower organisms, preserve the vegetative force in
spite of desiccation. At the same time I observed a
circumstance which deserves mention. In one of the
vessels a large number of diatoms were attached to
the sides of the glass : in these the endochrome never
returned to its normal condition. It is probable that
the plasma had been killed by too rapid a desiccation,
while the diatoms on the surface ■ dried less rapidly
as the substratum slowly lost its humidity : the
plasma was, therefore, able to contract slowly ; thus
preserving the power of returning to life under the
influence of favourable conditions. It seems, there-
fore, necessary, in order that the diatoms should
preserve their vegetative force, that the desiccation
should proceed slowly ; and that is exactly what takes
place in ditches and pools. After these facts, it is
easy to comprehend why, during the wet season, we
are able to find, almost directly, the diatoms for which
we have searched in vain during the drought."
{ATote by Translator. — These experiments will, I
think, not only account for the rapid reappearance of
the diatomacese in dried-up pools when these were
again refilled, but will also explain their presence in
such habitats as the moss on the trunks of trees,
roofs of cottages, or the damp places near leaky
water-butts or tanks. The debris from the dried-up
ditches is raised by the wind as fine dust, and carried,
perhaps, miles away, and after a time deposited in
the localities just alluded to ; the presence of moisture
not only soon restoring their vegetative power, but
enabling them to reproduce by self-division.
Those who have examined gatherings from the
previously-named sources have, no doubt, been
struck with the absence of the larger forms : these
have, probably, been eliminated by their rapid sub-
sidence, owing to their much greater weight.)

PRIMITIVE MAN :
HIS TIMES AND HIS COMPANIONS.
By the Rev. J. Magens Mello, M.A., F.G.S.
IN the history of almost all nations there is a point
at which that history loses itself in tradition and
myth, a point at which we should be left in im-
penetrable darkness were it not for the new light that
has been shed, at any rate, upon the past history of
man in Europe by the discoveries of the still young
science of Geology. When we attempt to trace back
the history of the human race in England, which we
may take by way of example, the earliest historical
records carry us back to the period of the Roman
Conquest ; the writings of the Roman Tacitus, and of
some other authors of that epoch, show us more or
less distinctly what kind of a countiy this was, and of
what sort the inhabitants were which they found in
possession ; and there history leaves us. We must
look elsewhere for any further information. That
information lay buried for long centuries beneath the
earth : in mounds, in caves, in gravel-pits the foot-
prints of primitive man were left for the explorers of
the 19th century to track and to interpret.
During the last fifty years evidence has been fast
accumulating, showing us that long ages must have
elapsed, ages marked by many changes, since man
made his first appearance here ; evidence slowly
received indeed at first, but which has yet surely
made its way, forcing upon us the belief that long
before the Romans visited our shores, generations after
generations of men had come and gone, men to whose
eyes was presented a very different England to that
with which we are acquainted, men who had as their
companions animals very different to those with
which we are now familiar. What that England was
probably like, what those animals were, and what
little we know about those men is the subject of this
present sketch.
Many ages before the Romans came there was a
time when England, instead of being an island,
together with Scotland and Ireland, formed part of
the continent of Europe ; there was then no Bristol
Channel, no Irish Sea, no Straits of Dover, no
German Ocean such as we now have them ; we must
picture to ourselves a northern and western extension
of the Continent with a great river, an enlargement
probably of the present Rhine, flowing northwards
through a wide valley or plain, where is now the sea.
Into this river flowed, as tributaries, the Thames and

Humber and other streams; dense forests, wild moor-
lands and heaths, great swamps and morasses,
diversified doubtless in places by green pastures,
stretched far away inland from this great valley, as
well as from others on the south and west of Eng-
land. In those early ages, no mild winters were
known, though probably the summers were far hotter
than any which we now experience. We may even
imagine, if we will, snow-covered mountains, with
their glaciers creeping down into the valleys, in which
the snow would lie thick as winter drew on, whilst
the rivers would be sealed up by ice. We may
picture to ourselves the animal life of that period. It
is winter ; from the northern hills and forests come
travelling southward, driven by the excess of cold,
animals now called Arctic ; and in the valleys and amid
Fig. si. Flint Implement from Brandon ; 3 nat. size.
the woods of middle and southern England might
have been seen the herds of rein-deer, the gigantic
shaggy-maned mammoths with their huge recurved
tusks, smooth-skinned but woolly rhinoceroses, great
bears, wolves, and foxes, crafty gluttons, troops of wild
boars and other animals. Spring and summer draw
on, and as these animals begin to move once again to
m ire northern pasture-grounds, we find with the
increasing warmth an influx of other visitors, strange,
indeed, to England now, — lions and tigers, and
leopards, hyaenas, hippopotami, elephants, and other
species of rhinoceroses; and thus, in the strange climate
ef those days, might have been witnessed a continual
swinging to and fro, and an intermingling for a time,
of Arctic and southern animals, who made this
c iuntry their home, and many of which were even
bo 1 here, and here lived and died. Do any ask,
! lo you know all this? is not all this a mere idle
die mi? Let us, then, record some of the evidence.
'J 1 :se animals have left us their remains to this day ;
-1 iiny a brick-field and gravel-pit, in the soil of
1 iinis caverns, their bones, nay, occasionally even
tl ir complete skeletons, have been found, and no
1 tee accumulation this, no stray bones are these,
v 1 ;hed in by some great flood or floods from distant
: jions. The evidence shows that many of these
1 les were deposited in the very spots near to which
t se animals died. Sealed up in the floor of many a
cave are these relics of the past, not water-worn and
rubbed, but fresh and sharp as to all their angles, some-
times also bone lying close beside its bone, as though
quietly dropped and covered up where found, as
must, indeed, have been the case, almost immediately
after death. Our cave floors give us proof also that
many of these animals, the rein-deer, hyaenas, mam-
moths, and others, must have been born in this
country. In the same bed, lying side by side, we
have found the young and the old, the rein-deer and
its fawn, the hyaena and its cub, the young as well as
the old elephant or rhinoceros, and a very brief
examination of the contents of some of our caverns will
demonstrate these facts ; we may not only see the
jaws, for instance, of the old hyaena with the teeth
worn by hard work almost to the gums, but also
those of the young animal, in which the permanent

teeth are only just sprouting and pushing their way
beneath the deciduous ones. Most of the teeth of the
mammoths found in caves are those of young animals,
and when we come to look closely at all the bones
and teeth, we are at once struck with the fresh-look-
ing conditions of the majority, and are convinced that
they can have had no long journey to perform between
the death and burial of their owners. Another thing
which we may observe in the case of bones found in
caves is that many of them are seen to be scored and
gnawed into their present shape by the teeth of some
animal, and analogy has led to the conclusion that
the great devourer of the bulk of the animals whose
remains are found in caves was the hyaena. This
savage beast in those early days, as now, was
in the habit of dragging its victims wholesale or
piecemeal into its den, where it devoured not the
flesh only, but also the bones, rejecting only the
very hardest portions ; and the teeth, then, left lying
about on the floor, would soon be covered up by the
mud brought in, partly by the frequenters of the
caves, partly by floods, and also by the slow deposits
from the moisture which found its way through cracks
and fissures. It seems a strange thing that such
animals as those spoken of should ever have been
found side by side in our country, — the northern rein-
deer and the southern hyaena, for instance. Some
geologists have not been able to realize that they
could thus have lived during the same season, and
HARD WICKE'S SCIENCE- G OSS I P.

have suggested that during those early times there
may have been warm and cold periods, each lasting
perhaps ten or twelve thousand years, and that ' ' the
southern animals lived in our island during the warm
periods of the glacial epoch, while the northern ani-
mals lived during the cold periods." That there were
such interglacial periods of warmth appears to be not
improbable, but, allowing this, I do not see how we
can, with the testimony of cave deposits before us,
fail to be convinced that northern and southern forms
did not make their appearance separately, each living
here for awhile and then disappearing, but that they
lived during long periods actually side by side. The
condition of the various bones found is such that they
undoubtedly convey the impression of perfect con-
temporaneity ; any way, they are found lying side by
side, without a vestige of rolling or wear and tear,

in deposits from a few inches to only a foot or two in
thickness ; a rein-deer bone, for instance, almost, if
not quite, in contact with the jaw of a hyaena, and
bearing upon it what we can hardly help believing to
be the marks of the hysena's teeth upon its surface.
The remains of Arctic and southern forms are so
intimately blended together, and present such simi-
larity of aspect in such caves, for instance, as those
of Creswell, and the gnawed bones of rein-deer,
rhinoceroses, and other animals are so exactly like
the bones gnawed by hyaenas of to-day, that the
evidence appears overwhelming that they all must
have lived side by side ; and the easiest way of
accounting for such a condition of things is to sup-
pose, as has been suggested, a seasonal immigration
and intermingling of the animals in a climate subject
to an extreme range of summer and winter tempera-
ture, unless we accept as an alternative that the
intermingling may have taken place at the com-
mencement or close of an interglacial period, but that
there was such an intermingling of forms appears to
be beyond question.
Now, when these animals lived in England, man
was their companion ; there is now not the slightest
doubt of that. The evidence, fifty years ago so
scanty, so incredulously received, has become over-
whelming. To take the evidence of caves alone :
in numerous caves in this country, in those of France,
Belgium, and Switzerland, traces of man's presence
have been found in vast quantity intimately mixed up
in the same beds in which the bones of the animals
are found, and showing most clearly that they must
have been deposited at the same time. And is it
asked, what are those traces? Have you any
human bones ? The answer is, not many. A few
have been found in some caverns, and these have been
found to be in exactly the same condition as those of
the extinct animals ; but I do not think that we have
any right to expect to find many bones, and one
reason is that although man was then present, his
numbers were few indeed, compared with the vast
multitude of wild animals. Why, even as recently
as the time of Queen Elizabeth I believe that the
population of all England did not exceed that of
London to-day. Man would then be in the propor-
tion of one to many thousands of wild animals, with
whom he would have to wasre a hard and often

precarious struggle for existence. And again, if the
men of those primitive times neglected their dead, as
do some tribes of men now, the hycenas, wolves, and
other animals would not leave many bones to tell the
story of man's existence. What we do find to prove
that man then lived are his weapons and his tools, —
rude, indeed, at first, and ill formed, but yet showing
a certain amount of design and intention in their
shape never to be found in mere naturally-broken
stones. Man's first tools and weapons were the
pebbles picked up around him, rudely fashioned for
such simple work as he required them to perform by
a few pieces chipped off here and there, to enable
them to be more readily held in the hand, or fastened
into holders of bone or wood ; such rude tools would
serve as hammers to break bones for the sake of their
marrow, to scrape the skins of animals killed in the
chase with the primitive stone-headed lance or arrow.
Implements of this primitive character have been
found in abundance in the lower beds of some of the
caves of this and other countries, as well as in the
ancient river-beds. In England, the caves of Creswell
and that of Kent's Hole have furnished many highly
characteristic specimens of these earliest efforts of
human skill, whilst the gravels of the Thames Valley,
of the Ouse and other rivers in this country, and
those of Amiens and Abbeville, amongst others in
France, have also furnished numerous examples, some
made of quartzite and other pebbles, others of flint. In
the case of the rude hammer-stones, little has been
78
HARD WICKE >S S CIE NCE - G OS SI P.
done to the original pebble beyond giving it a suf-
ficiently convenient form to enable the user to grasp it,
but the bruised and battered face of the implement
clearly shows to what use it was put. In the scrapers we
see that a sharp edge has been placed by skilful blows
on one side of the stone, whilst the other has been
probably fastened into some kind of holder. Primi-
tive man would very soon have discovered that few of
the stones commonly met with more readily adapted
themselves to his wants than the flints so common
wherever there was chalk, or, indeed, often found
scattered here and there in gravel-beds and other
spots at some distance from their original source.
The sharp edge of a broken flint, the comparative
ease with which it could be variously shaped, soon
led man to prefer it to other materials.
The razor-like edge of a flint-flake would be found
to make an excellent knife, and such long thin flakes
are amongst the implements most commonly met
with. They are usually flat on one side, with a well-
defined bulb of percussion at one end, — a proof of
their having been struck by a deliberate blow from
the original block ; a mere splinter broken accident-
ally by the crushing of a mass of flint never has this
well-marked protuberance. The upper surface of these
flakes has also two or more faces, giving to the specimen
in section a more or less triangular aspect. Broader
flakes, with a sharpened edge at one end, would
adapt themselves as scrapers. We also often find
flints with very carefully-worked points, which may
well have been used for boring holes in fragments of
bone, to form needles, and they might be used, too,
for piercing the skins, that the bone needle might
more readily pass through. Some of the most
primitive implements were large, somewhat oval-
shaped, ones, made of flint or some other hard stone ;
these, which are frequently found in the old river
gravels, and some of which are made of quartzite
pebbles, have been discovered in the earliest beds of
the Creswell caves in England would, if bound firmly
into a handle, serve as formidable axes or tomahawks,
and were probably used as such.

THE REAPPEARANCE OF AN OLD
FRIEND.*
BRITISH natural history has produced few works
which have become national classics. But
White's " Natural History of Selborne" undoubtedly
takes rank as such, and finds its place on our library
shelves side by side with Goldsmith and Addison.
The unaffected and graceful simplicity of the style,
the cheerful and yet reverential tone of thought, the
quiet love for all that lives, the keen power of
observation, and the readiness to draw correct in-

ferences from complex facts, have rendered this work
the most popular of its kind that was ever written.
There is a freshness and a charm about every page,
which seems imbued with the breath of the green
fields, and the spirit of the silent woods. One returns
to its occasional perusal with delight. It appeals as
successfully to youth as to age, and commands its large
circle of readers by reason of its broad sympathies.
Naturalists and non-naturalists alike confess to its
charm. Perhaps no other English work on natural
history could have borne half the editing which
White's "Selborne" has had to experience. We
have editions of all kinds, voluminous and com-
pendious, editions de luxe, and "cheap editions for
the people" ; and still the work has lived throughout.
In our opinion the present edition of White's cele-
brated book is the best which could possibly be
produced. There are many reasons why this should
be the case. First of all the editor, Professor Bell,
is himself one of our best naturalists and natural-
history writers. No man more fully recognizes the
scope of his work — no living naturalist has more
pleasant memories of by-gone workers. Moreover,
Professor Bell has lived in White's house at Selborne
for the past thirty years, and so must have become
imbued in no small degree with the spirit and charm
of the place. This edition of White's work has,
therefore, been edited in the house where it was ori-
ginally written. The style in which this edition has
been published demands a few words of remark. The
binding of both volumes is after the modest style
which White would have undoubtedly preferred. The
engravings and woodcuts (not numerous) are of the
best kind of artistic work ; the paper is excellent ;
the type large and cheerful ; and there is an absence
of those abounding foot-notes in small print on every
page, which, in some editions of White's "Selborne,"
have made its perusal almost a torture.
After saying thus much for the manner in which
this edition has been brought out, we have next to
draw attention to several matters in which it differs
from all previous editions. A few years ago a series
of twenty letters, constituting a correspondence be-
tween Gilbert White to Robert Marsham, of Stratton,
Norfolk, were discovered, and published, we believe,
in the "Transactions of the Norfolk and Norwich
Naturalists' Society," accompanied by a notice of
Mr. Marsham's life, by Mr. Thomas Southwell, hon.
sec. These letters are included in the second volume
of the present edition. In addition to them are other
letters and correspondence of Gilbert White's, which
now appear in print for the first time. Such is the
correspondence between himself and his brother John,
who was English chaplain at Gibraltar, and after-
wards vicar of Blackburn, in Lancashire. In these
letters we gain a loveable knowledge of Gilbert
White otherwise than as a naturalist. His brother
seems to have been as simple-minded and guileless as
himself, and this correspondence has a quaint, affec-

79
tionate, brotherly, but unfortunately old-world charm
about it that almost makes one sad. The Rev. John
White was a correspondent of Linnaeus, six of whose
letters also appear in these pages. Another corre-
spondence consists of a series of letters, also now first
published, between White and his brother-in-law, Mr.
Thomas Barker, of Lyndon Hall, Rutland, and the
latter gentleman's son. Natural history and archae-
ology are the chief subjects herein pleasantly dis-
cussed. The correspondence between the well-known
naturalist Pennant and Gilbert White form the bulk
of the first portion of the work. In addition to the
above new additions to White's " Selborne," ren-
dering it richer and fuller than any previous edition,
Professor Bell has had the sympathetic aid of several
modern naturalists, among whom the suggestions of
Professor Alfred Newton on that part of the work
relating to Birds, have unquestionably raised its
authoritative value. All lovers of natural history and
English classics who can afford it, will have this best
edition of White on their library shelves ; and all our
provincial scientific societies and clubs ought to
include it in their circulating list.
THE HARVESTMAN "SPIDER."
THE animal which from the enormous length of
its legs has attracted the notice of most per-
sons from childhood upwards, seems from its very
slight resemblance in external appearance to the form
of a spider to have received a name to which it is
not at all entitled ; some of the peculiarities of spiders
are so exceptional to the general characteristics of all
other living beings, that no creature in which they
are absent ought to be called a spider. I am there-
fore induced to compare the harvestman with an
ordinary spider, in the hope that some one will suggest
its appropriate name.
The first difference that strikes the most superficial
observer is, that the bodies of spiders are divided into
two distinct portions by a very slender waist which
connects the abdomen with the chest and head ; in
the harvestman the head, chest, and abdomen are all
under one shell or horny covering, without any waist
or division. The most remarkable feature in spiders
is the position and character of the reproductive
organs. In the female spiders they are on that por-
tion of the abdomen next the waist, and in the male
spiders in a much more extraordinary position, being
connected with the head of the animal by the palpi ;
a further exception to the prevailing order of nature,
and equally remarkable, is seen in the fact that each
male spider has two distinct and complete organs,
one in each palpus, and both exactly alike, one not
being the complement, but the exact counterpart of
the other. In the different species of spiders these
organs vary in a greater or less degree, so that by
these differences species might be determined ; some
of them are extremely complex and beautiful, as in
Lyniphia marginata, others, though more simple, are
still worth studying. May not the absence of this re-
markable apparatus in the harvestman be considered
a conclusive answer in the negative to the question,
Is it a spider ?
Those who have not the opportunity of examining
these organs microscopically I would refer to Black-
wall's celebrated treatise on spiders, where they will
be found beautifully illustrated. This authority says,
spiders moult or change their skin from five to nine
times, according to species ; that the male sexual
organs are not commenced in their development till
the penultimate moult, and are not completed till the
final moulting : now in the harvestman the sexual
organs are found in the smallest individuals. In the
harvestman there is one slight approach to the resem-
blance of spiders, the position of the reproductive
organs being similar to that in the female spider, viz.,
nearly close to the chest ; in the harvestman the
position is the same in both sexes, there is, however,
no difficulty in distinguishing one sex from the other ;
in both sexes the organ is situated within a flexible
tube by means of which it is drawn within the abdo-
men, or projected externally, both organs are repre-
sented in the following sketches (figs. 55 and 58).
In the male organ the parallel lines represent the
membraneous tube, the shaded portion the horny
instrument which slides within it by introversion, or
something like the tube of a telescope ; it may be seen
in its normal position (after the body has been
rendered transparent) seated within the abdomen
with the hooked point near the external orifice, this
hook is attached to the shaft by a movable joint, and
the hairlike termination of the hook is also jointed,
so that it is possible to place the hook in a line with
the shaft, though it is always found at a right angle
as represented ; the length of the organ with its
elastic tube extended is about as long as the diameter
of the body, the horny portion being a little shorter
than the membranous. The female organ, from the
great length of its elastic tube, which is about twice
as long as the body of the animal, is probably used as
an ovipositor, the horny portion is not more than one
third the length of the elastic tube ; the latter, how-
ever, when drawn within the body is shortened by
contraction to the length of the horny part then con-
tained within it. This part appears to be formed of
a series of bands or rings connected together and
terminating in lobes, to which are attached strong
tufts of hair, or spines, the bands are covered with
stout hairs about as long as the width of each band,
and the membranous tube is so thickly studded with
minute hairs, that when contracted within the body
the organ appears black, the surface resembling that
of a steel rasp. It might be supposed that a tube
that has to slide within itself by introversion would
be greatly impeded by the friction arising from its
surfaces being prickly instead of smooth. If we ask
So
HARD WICKE *S SCIENCE -G OSSIP.
what purpose do these hairs serve, or why is it that
all other internal organs being so perfectly adapted
by their smooth and lubricated surfaces for moving
together without friction, these should present a
roughened surface, we might learn a lesson of
humility by reflecting that as we proceed step by step
in our investigations of the mysteries of nature, we
are continually finding how inadequate is the capacity
of the human mind to comprehend the designs of an
omniscient Creator. I now proceed to the considera-
tion of the breathing organs. Spiders breathe by
branchia, organs somewhat resembling the gills of
fishes, being a series of thin membranous plates
placed together like the leaves of a book in two
clusters within the abdomen, one on either side the
spiders says, " the foot (or portion corresponding to
the tarsus of insects), is divided into two parts, the
tarsus and metatarsus, and in some species into three
joints." The tarsus of the harvestman has in some
cases as many as ninety joints, the lowest number I
have met with being twenty-five. The feet of spiders
are terminated by two or more claws, generally pec-
tinated ; those of the harvestman have only one claw,
curved, but quite smooth. The palpi of the harvest-
man closely resemble those of the female spider,
excepting that the claw at their termination is
generally, if not always, pectinated in the spider and
smooth in the harvestman, though I have found two
instances in which the claws of the palpi were pecti-
nated, although those of the feet of the same

individuals were not so. The absence of spinnerets
distinguishes the harvestman from the generality of
spiders, but as some few species of spiders are also
without them, this is not a difference of so positive
a character as the other points I have noticed. The
last organs to which I would draw attention are the
fakes : in spiders these are terminated by a curved
claw sometimes deeply serrated on its inner side ; in
the harvestman the termination is a pair of forceps or
nippers like those of a lobster or crab. These fakes in
most of the harvestmen are rather smaller
than we find them in spiders, but in some
cases they are fully three times larger than
we find them in any of the spiders, and
assuming quite a different form ; in fact,
they no longer resemble reaphooks, from
which they derive their name of fakes, but
are much more like pickaxes : therefore, following
the same kind of nomenclature, I propose bipenni
as an appropriate name for them ; the fig. 57
shows an outline of their peculiar form and the
comparative size that the bipenni and the fakes bear
to each other. All the specimens I have found
possessing bipenni were males ; I think, however,
these organs do not distinguish the sexes, but a
difference of species, as both males and females
are found bearing the fakes ; as the upper spur or
arm of the bipenni is not present in those in-
dividuals that are less than half grown, I think it is
not fully developed till the last moult, as in some
that are about three-quarters grown it is very short

sexual orifice in the female. The air is admitted
to these branchia through stigmata, or horny plates
having fine irregular openings, presenting the appear-
ance of a grating, corresponding in some measure to
the spiracles of insects. The harvestmen breathe by
trachea, the same as insects ; there are two spiracles,
one on either side of the abdomen ; the principal
tracheal tube proceeds a short distance from each
spiracle, and then divides and subdivides, permeating
every part of the body. The eyes present a difference
in number only to those of spiders ; Blackwall says,
" the number of the ocelli in spiders is always two,
six, or eight ; " in the harvestman the number is
four. The same authority in describing the legs of

Having now shown (as I think conclusively) that
the harvestman is not a spider, will some one tell me
what it is ?

THE MIGHTY DEEP.
IN a general way persons have a better appre-
ciation of the vastness of the land than of that
of the sea ; mainly because the former is more fre-
quently forced on their attention. The area of the
ocean is nearly thrice that of the land ; the one
being estimated at about 52 million square miles,
and the other at 145 million square miles. On the
land, as well as in the ocean, there are vast tracts on
which life is absent or scanty ; but whereas, on the
land the inhabitable portion is to a great extent
superficial, in the ocean life occurs more or less I
abundantly at all depths. The ocean forms one
continuous mass of water broken up into irregularly-
shaped portions by the land. When portions of
the sea are inclosed by the land, the water under-
goes so marked a change in character that such
inclosed portions (forming lakes and lagoons) can
no longer be considered as forming part of the
ocean. The sjreat bulk of the sea is concentrated in
the South hemisphere, and the pole of the sea (that
is, the centre of the hemisphere in which it is most
extensive) is in 520 S. 6° E. In this hemisphere
the land is to sea as 1 to 8, while in the opposite
hemisphere there is nearly as much land as sea.
The mean depth of the sea has been variously
estimated, but as yet there are scarcely sufficient data
for accurate estimates. Buffon suggested it might
be 200 fathoms or 1,200 feet ; Lacaille, 163 to 273
fathoms; Laplace, 656 fathoms ; Lyell, 2,600
fathoms ; and Herschel, 3,520 fathoms. The most
probable mean is about 2,600 fathoms. Assuming
this as correct, the average volume per square mile
would be 418, 176 million cubic feet, and the total
volume 60,635,520,000,000 million cubic feet. The
mean height of the land is 1, 000 feet above the sea-level,
which would give a volume of 1,449,676,800,000
million cubic feet for the supramarine portion.
Hence the ocean's bulk is 41 times greater than that
of the land above its upper surface.
One of the causes now in operation which tend to
make the ocean encroach upon the land is the intro-
duction of detrital matter into the sea. Every grain
displaces its own bulk of water, and so far causes it
to encroach upon the land. Denudation is always
going on at a probable mean rate of one foot in
3,600 years, at which rate all the land would be
removed in about ten million years. The sea, in
that case, would gain on the land at the mean rate of
about five square miles per year. If all the land
were transferred to the sea, the mean depth of the
latter would be reduced to 1,500 or 1,600 fathoms.
Other causes, however, may influence the extent of
the ocean. One is the subsidence of land below the
sea-level and elevation or subsidence of the sea
bottom. The subsidence of the whole of the land
would involve a depression of about 30,000 feet ;
and the elevation of the whole of the sea bottom
would require an uplift of about 35,000 feet. In all
probability elevation and subsidence proceed simul-
taneously in different parts of the earth, and may or
may not counterbalance each other. The bearing of
this conjecture is that extensive subsidence or eleva-
tion of the sea bottom is calculated to be more in-
fluential than the introduction of sediment in causing
the sea to advance upon or withdraw back from the
land. The introduction of a mass of matter equal in
bulk to all the supramarine land would be sufficient
to cause the ocean to overflow the land up to about
the level of 6,000 feet above the present level ; while
alterations of level less than those of which the
geologist is cognizant, as local phenomena at least,
would, if extended over large, areas account for the
displacement of entire continents and oceanic basins.
It has been assumed that the bulk of the ocean has
been approximately unaltered; but surmises might be
made upon the variations in the amount of water
which, in its aeriform and liquid states, is temporarily
withdrawn from the sea. A rough calculation indi-
cates that the average amount of vapour constantly
in the air corresponds to about 13,412,704 million
cubic feet of water, and that the amount of fluid re-
quired to keep all lakes, rivers, &c, supplied for six
months is about 2,364,072,004 million cubic feet, or
about sufficient to form 5,894 square miles of sea of
average depth. The entire absence of all flowing
fresh waters, or a doubling of their present volume
(extreme conditions which are not likely to have hap-
pened), would have no appreciable influence geolo-
gically in altering the relative areas of land and sea.
The accumulation of snow and ice would perhaps be
more influential. For, supposing it possible that at
one time there were no ice, and that at another some
10 million square miles were covered therewith to a
depth of 500 feet, this would give a volume of
139,392,002,000 million cubic feet, which cor-
responds to 309,071 square miles of sea of average
depth. If we assume that the sea has retained its
mean depth unaltered, the utmost probable irregu-
larity in the amount of "rainfall and in the accumula-
tion of ice upon the land would not cause its area to
vary by so much as one million square miles. Hence,
from a geological point of view, the possible influence
of such irregularities may be disregarded. There is
yet another influence to be noticed. It is exceed-
ingly probable — nay, we may say certain — that the sea
bed consists of material which is in places permeable,
and in others impermeable, to sea water. At what
rate the water percolates into the rocks, and what
82

quantities are retained in them temporarily, we are
not prepared to state ; but it does not seem likely
that the rates of absorption and evaporation have
varied much. A certain portion of the water, how-
ever, remains in the rocks for prolonged geological
periods, and it is believed the amount is constantly
increasing. It is not known what the amount may
be, but there seems to be no reason to suppose that
it has affected the volume of the ocean to any large
extent. The conclusion at which we arrive is that at
every geological period there has probably been water
somewhere on the earth's surface, having a mean depth
of over 9,000 feet. It has been suggested that comets'
tails may have condensed on the earth, and, as a conse-
quence, given rise to floods ; but such speculations may
be dismissed as purely imaginative. The attractive in-
fluence of the land draws the ocean above the level it
would otherwise have, and thus causes the water to
encroach upon the land ; but such elevation of the
water is a local phenomenon only, the mean level of
the ocean being in no way affected.
The existence and, to a large extent, the conditions
of the present sea are indicated by direct evidence ; .
but the position, depth, and conditions of the seas of
former periods can only be ascertained by indirect
means ; and mainly from the fossil remains found in
strata. The occurrence of a species belonging to a
group of organisms which, so far as known, is exclu-
sively marine, is a fair proof of the co-existence of
marine conditions, provided, of course, such remains
have not been introduced by accident or by derivation
from older marine beds. In most cases collateral
evidence sufficiently indicates whether the stratum is
or is not marine. The distribution of marine or-
ganisms is dependent upon circumstances, so that a
study of these in the case of living species enables us
to infer, more or less correctly, some of the condi-
tions of the sea in which they lived ; and amongst
others that of the contour or depth. The matter is,
however, somewhat complicated, for it would seem
that depth alone has little influence on the distribu-
tion of animals and plants, and that the influencing
conditions are temperature, light, food, currents, &c.
The evidence then which fossils afford as to depth is
probably wholly circumstantial. In the present seas
the greater depths are associated with a low tem-
perature, slow currents or movements of water, sedi-
ments of extreme fineness, and absence of solar lumi-
nous rays ; the probabilities are that such has always
been the case in the older oceans ; but the only con-
stant condition associated with great depth is absence
of the sun's light. In closed seas the temperature
may be high at great depths, and under certain con-
ditions moderate currents may exist in the deepest
oceans. In a general way shallow waters are asso-
ciated with the stronger currents, the coarser deposits,
varied conditions of temperature and accessibility to
solar light. Deposits of extreme fineness may occur
in shallow and cold seas, which conditions would be
nearly the same as those of the deepest seas ; for,
irrespective of depth, the principal difference is pre-
sence of light in the shallow water. This would
allow of the existence of species to which ordinary
light is directly or indirectly essential, along with such
of the deep-sea forms as could live in association with
them. In the shallowest waters along the sea margin
we find a certain relation between the depth and
particular groups of species of organisms ; but ex-
amination shows that this relation holds because
certain conditions of temperature, exposure to air,
food, &c, concur with such depths. These condi-
tions may correspond with a certain depth in one
area and with a different depth in another area ; so
that it becomes necessary to take many circumstances
into account before drawing conclusions as to depth
from the association of certain species. When the
conditions regulating the co-existence of particular
species are known, we can readily infer somewhat as
to the depth of the water. These considerations have
an important bearing upon the geographical distri-
bution of species and the inferences deducible from
such distribution in space and in time, and, conse-
quently, upon the continuity of oceans in space and
in time, or, rather, on the continuity of certain oceanic
conditions. A. Ramsay.

BOTANICAL WORK FOR APRIL.
THE early part of the present month will be the
season to work at several species : thus, the
common Pilewort [Ranunculus Ficaria, L.) is now
in full bloom in some parts of Britain. We have
been recently taught to regard it as comprehending
two distinct species ; for example, it is divided
into two varieties, viz., a. diverge/is, F. Sch. ;
b. inatmbens, F. Sch. The first variety, a, has lobes
of lowest leaves not oz'crlapping at the base, lowest
sheaths narrow : variety b, incumbens, has lobes of
lowest leaves overlapping at the base, or parallel with
petiole and lowest sheaths, very broad, amplexicaul.
Which of these varieties occurs in your district ?
It will make many a walk pleasant and delightful to
know one is helping to clear up a question not yet
satisfactorily answered.
In the south of Europe another form is found ; in
fact, a distinct species, named by most botanists
Ranunculus Ficariaformis. Have we not overlooked
it in England? It is very similar to our plant, and
may quite possibly have been passed over. Let it lie
cleared up this spring.
Viola sylvatka, Fries. — This is another species
which can be worked up in April. Most of our
readers are aware that from the days of Linnceus
until a very few years ago, this plant passed current
under the old name of V. canina; nay, not a few still
persist in knowing it under the old name, and refuse
to listen to the '"new species." Linnceus's name
HARDWICKE'S SCIENCE-GOSSIP.
{canina) was applied by him to the present and
another species, V. canina of Babington's "Manual."
When it was found needful to separate the two, this
name was restricted by Fries to the one now recog-
nized as the true canina, and he proposed sylvatica
as the present species. Most European botanists at
once adopted his views, but it was some time before
we recognized the new species. But we wish to call
the attention of our readers to another fact, which
may be advantageously worked at in every district,
for V. sylvatica comprehends two well-marked
varieties, viz., a. Riviniana, b. Rcichcnbachiana.
We have many book species, with not near the
distinctive characters possessed by the above.
V. Riviniana, Rich., has the leaves broadly cordate,
acute ; calycine appendages persistent, broad ; petals
blue, remarkably broad, lower one with many
branched veins at its base ; spur thick, cream-coloured,
or very light blue. V. Reichenbachiana, Bor. , leaves cor-
data, prolonged; calycine appendages small, narrow ;
petals bright lilac, lower one with parallel, few, nearly
simple veins at its base; spur flattened, light lilac. If
the above varieties are once recognized, they will
never again be mistaken. The common form, that
often called V. canina, Linn., is seen as a roadside
plant on every sunny bank or sandy lane in
the northern counties, but V. Reichenbachiana is
generally found, and then very sparingly, in deep,
damp ravines and glens, where the sun seldom
penetrates, although sometimes seen on the same
bank with the common form. It may be identified
at a glance, the peculiar lilac petals exceedingly
narrow when compared with any other species ; also
the narrow, often sharp-pointed spur, just tinted with
pale lilac : the leaves are, when young, pale green,
not thick, fleshy, and dark green, like Riviniana,
and it is altogether the prettiest violet known in the
British islands.
Draba vema, L. — Continental authors make six
species out of our earliest spring gem, the " Whitlow
Grass " {Draba vema). We have often wondered
how many of these could be found on our old walls
or sandy pastures. After fifteen years' experience in
the northern counties and Wales chiefly, we can only
detect three varieties, for we do not think they can
fairly take rank as species. From Boreau, "Flore
■die Centre de la France," we take the following; so that
our friends, who may have the opportunity, may work
them out : — I. Erophila (Draba) brachycarpa, Jord.
Leaves oval, lanceolate, narrowed at both extremities,
entire, clothed with simple and bifurcate hairs ; flower-
stalks slender ; sepals oval, hispid ; petals oboval,
oblong ; pedicels flexuose, 2-4 times longer than the
silicules ; silicule very obtuse at summit ; seeds
elliptical, few in number. Loc. old walls and
rocks; " the first to flower." 2. E. glabrescens, Jord.
Leavesdark-green, lanceolate, narrow, gradually taper-
ing into a long petiole, often smooth ; sepals oval, a
little hairy ; petals oboval, oblong, with slightly
spreading lobes ; pedicels hardly three times as long
as the silicules ; silicules nearly evenly oblon) in straightforward
flight it has neither the dash nor the rapidity so no-
ticeable in the Sparrowhawk. It flies along gently,
while the Sparrowhawk sweeps rapidly on, now
swooping at this, then at that, {c) When seen off
the wing, the " Windhover" is also easily known by
its inclined and rather stooping posture, while the
Sparrowhawk stands "as straight as an arrow," bid-
ding defiance to everything by all its movements and
actions. Even the uncouth country-lad can perceive
the difference between these two, for, on asking a
little rough-headed boy on the outskirts of Sheffield
if there were " any hawks about there," he replied,
" Which hawk do you mean ; the one which catches
pigeons, or the one which stands still in the air?"
— by the former, meaning the Sparrowhawk, and the
latter, the Kestrel. The Kestrel takes great delight
in tormenting other birds, — above all, the Owl
(Strigid(c), which appears to be the "laughing-
stock " (if I may so use the expression) for all birds.
The cry of the Kestrel is a strong, wild, ringing note,
which becomes harsh and loud on the threatened
approach of any danger to either its young or its
eggs.
Flight. — The flight of this bird is very light and
airy. Generally, it flies at a moderate distance from
the earth, but during, or rather on, the choice of a
building site it soars high up in the air, when its
actions are most elegant. The question then arises,
" What is the Kestrel's object in soaring so high?5'
Fig. 70. The Kestrel {Falco tinnuncuhis).
"Is it seeking to discover food from so great an alti-
tude?" No. It is the joyousness of the bird which
prompts its lofty flight and graceful evolutions so
high up in the heavens. When on the ' ' look-out ' ' for
sustenance it flies at a moderate elevation, that it
may drop down suddenly and unexpectedly on its
prey and secure it before it has sufficient time
to escape. If the "Windhover" attempted to
descend (even were it possible for it to discern ils
prey from the great height to which the Kestrel often
ascends) its intended victim, startled by the rushing
noise which the bird's velocity causes in descending,
would have time to escape the talons of its would-

be captor. .Kestrels are very early risers, and are
busily employed procuring food almost as soon as
night rolls back her gloomy mantle and the wide
east is tinged with the rosy hues of the rising sun,
and pursue their vocations until it becomes dusk ;
and even then, long after the brilliant orb of
daylight has disappeai-ed in the far-away ruddy
west, and the soft twilight of a summer's even-
ing has overspread the country, they may be seen
lightly skimming over the surface of the earth in
search of food. As the compact body, great extent
of wing, and fan-like tail of the Kestrel indicate, it
has great command of itself in the air, making long
sweeps and elegant curves in the ethereal regions.
It is, indeed, a beautiful performance, and one we
all delight in witnessing on a fine, clear summer's
day, the Kestrel, quite at its ease, with nothing in
the blue sky above but itself; its movements so
unconstrained, and withal so replete with joyous-
ness, as it revels in the celestial atmosphere in perfect
harmony with the surrounding landscape. The
wings and tail are expanded, and seem scarcely to
move as their owner ascends and descends in grace-
ful curvets. Now it takes a longer and a higher
sweep than usual, and then, coming low, keeps on
circling, now here, now there. Suddenly it stops !
Probably it caught a momentary glance of some
small animal ! No ! It again resumes its flight,
again it is wheeling majestically aloft ! It hovers
again ! What a beautiful object ! How pleasing are
its actions, as it "stands anchored," as if sus-
pended by some invisible cord from on high ! Its
head is turned a little on one side, its tail spread
out like a lady's fan ; it is watching with its keen
eye some small animal it intends to catch, probably
a field-mouse little aware of the fatal danger which
menaces it. In what fine style it comes down on
that unfortunate mouse, which it soon bears away in
its talons, to its craggy fastness in yon distant wood,
there to be torn to shreds by four or five hungry
young " Standgales." When the Kestrel is hovering,
its wings, although to the naked eye they do not
appear to move, are in a perpetual quiver. Suppose
the Kestrel be unsuccessful in one attempt, it repeats
its efforts, and so on, until it reaches "home."
But there is not a field, valley, pasture, or any place
at all likely to furnish it with food, which it passes
without a strict search. The beauty, smoothness,
and facility with which all these evolutions are
executed are beyond the power of the pen to
adequately describe. No ! You must go and search
for it amidst its haunts, and watch it in its re-
treats, before you can fully appreciate the character
of this bird. Sometimes we can just discern it like
a mere speck on the horizon winging his way slowly
under the clear, blue canopy of heaven. At other
times it moves along at an immense height until it
disappears beyond the verge of the distant horizon.
In fact, on the wing, this bird appears indefatigable.
What would be the value of scenery were it not
enhanced by the presence of birds ? How dreary and
desolate, how desert-like would be the vast expanse
of heather-covered moors without the hoarse cackle
of the Red Grouse (Tetrao Scotictis vel Britannicus)
or the Curlew's {Numenius arquata) solitary cry !
What would be the aspect of our woods were we not
in Spring-time, and, indeed, throughout the Summer
months, to see the Kestrel hovering over its leafy
bowers ; or what of such diversified scenery as is to be
J met with in and about the " Peak district," were
we not to meet with the "Standgale" amidst its
fastnesses ; or of the lakes, were not the still solitudes
to be awakened by the plash of the water as the Coot
{Fulica atra) or Moorhen, startled by the intruder's
presence, dashes away to gain shelter among the
j many islets which dot its surface ; or the shrill piping
1 whistle of the Sandpiper (Totaiius hypoleiichos) as it
■ hastily wings its way across the watery expanse, to
some other part ? Were the world to be deprived of
birds, it would lose one of its most powerful charms.
Migration. — We have now arrived at the most
interesting, but, at the same time, vexing portion of
'■ the history of this bird, viz., its migration. Does
• the Kestrel migrate wholly or partially from Britain ?
or does it merely move to other localities in our
j island more congenial to its habits? I have been
much interested in this question, and have studied it
I deeply, — at least, as regards the immediate vicinity
of Sheffield. It has proved a most interesting study.
We all know what a distinctive feature are the elegant
aerial evolutions of this bird in our summer scenery,
and how blank seems the wood which is not in-
habited, or, at the least, its neighbourhood frequented,
by a pair, or more, of these beautiful little falcons.
i After the breeding season, when the young have been
reared and are able to fly, we see them very often
hovering over the waving golden corn-fields, or other-
wise engaged in search for food. Then, after a brief
interval, they suddenly disappear without any warn-
\ ing, and we do not again see them until their appear-
ance in early spring. The period of departure, of
migration, varies, according as the weather regulates.
If winter sets in early, they "go away" about the
latter end of September, but if the season be fine and
open, they may prolong their stay until the earlier
portion of October, and by the end of that month not
one is to be seen. Whither are they gone ? Happily
the days have gone by when people were deluded by
the supposed fact of birds hiding in holes, and there
remaining in a dormant condition until spring's
verdant call awoke them. There is but one con-
clusion. It was Charles Waterton's opinion that the
majority of these birds migrate to other more
southern countries, leaving here, according to his
observations, about October. He had excellent
opportunities for the observance of their habits, and
yet lie never saw them in winter after their final
departure. Certain it is that we see but very, very

few of these birds from October to the middle
of February. In my opinion, they do migrate
wholly to other countries. Coming from the North
and joining those in the south of Britain, they
assemble, cross the Dover Straits, and, although
numbers may stay in the provinces of central France
and northern Spain, I have reason to believe that
the immense majority cross the Mediterranean along
with the numberless birds that periodically do
so, to the northern shores of Africa, whence they
commence their return during the month of January,
arriving in Britain in the course of the succeeding
month. The few (and they are but few) exceptions
met with during the winter months only tend to prove
this, and we must treat their appearances as those of
the casual swallows which often appear at unseasonable
periods.
Food. — As I have before said, this bird is not so
destructive to poultry or game as is the sparrow-
hawk. It is also a much more sociable bird, and is
more frequently seen near the habitations of man than
the former. Its food consists of the smaller mam-
malia, such as rats and mice, also beetles and other
destructive insects. Charles Waterton says that it
consists "almost entirely of mice." For the vermin
this bird destroys, its life should not be sacrificed as
it is by gamekeepers, who, almost without excep-
tion, seem to have the most ungovernable aversion
to all kinds of hawks. A great observer of the
economy of birds, Mr. Booth, says, "The rats
alone which these birds destroy while procuring food
for their young would commit more, ten times more,
damage in one year than a pair of Kestrels could in
their joint lives." The Windhover does, indeed,
occasionally have a change in its diet in the shape of
a small or unfledged bird, and, as sure as it does so,
it is either caught or seen "red-handed" by the
keeper, who, having seen its partiality to birds,
firmly believes that all its food consists of such, and,
acting on this illusory belief, he exterminates this
really useful little hawk and points out with evident
satisfaction the ominous row of Kestrels suspended in
a conspicuous position in his "museum." *
Mice are swallowed whole, the indigestible parts
being afterwards cast up in the form of pellets.
Insects are dexterously caught while on the wing,
being clutched with either foot and adroitly conveyed
to the mouth without at all impeding the flight.
Representation in other Countries. —
Though not found in Australia, the Kestrel's place
is well supplied by the Nankeen Kestrel ( Tinnwicu-
lits ccnchroides, Gould). As before mentioned, the
Kestrel's flight is very buoyant, but what must that of
* I notice in the Zoologist for April a remarkable instance
of this. On p. 120 of that periodical Mr. W. A. Durnford,
writing from the Lake district, says : " A kestrel rose from
the embankment within a few yards of me, with a large object
in its claws. ... It dropped its prey, which on examination
proved to be a full-fledged young cuckoo, dead, though still
warm."
its Antipodean representative be, of which Gould says,
"The flight of the Nankeen Kestrel differs from that of
its European ally in being more buoyant and easy " ?
In North America this bird is partially represented
by the American Sparrowhawk, which partakes of the
character of both the Kestrel and the Sparrowhawk.
Distribution. — It is the commonest of the
Falconida? which frequent our isles. Charles Water-
ton had numerous Kestrels in his park ; he, himself,
visited in 1835 no less than twenty-four nests, all
having Kestrels' eggs in them. I have never since
heard or read of so many being found in so small a
space, but, of course, he had them strictly preserved.
Around Sheffield its nest is not found as frequently as
that of the Sparrowhawk, although I have seen the
bird oftener. In many parts of Lincolnshire it is
also very common. It is very frequent in Scotland,
breeding mostly on the precipitous and craggy rocks
which fringe its shores. In Ireland, Mr. Thompson
says, "It is common and indigenous to suitable
localities throughout the island." It is found in most
European countries, even as far north as Lapland,
where "Old Bushman," in his trip up there in 1862,
procured specimens of both skins and eggs of this
bird. Specimens of it have also been sent from all
portions of Asia and Africa.
Nidification. —One cannot fail to be struck by
the facility with which the " Standgale " adapts itself
to places of nidification. In sylvan localities it
constructs its nest mostly on a tree, but if the spot
chosen be a wild, mountainous, but picturesque
district, either on the coast or in the interior, it will
be placed in some crevice in the rock. Sometimes
the nest is placed in the interstices of a dilapidated
old barn, or, perhaps, it is situated in a church tower.
The rough and hastily-composed structure which
serves for a nest is quite adapted to the contiguous
wildness. The "Stannelhawk " is but too glad to
avail itself of the deserted nest of any of the Cor-
vid we have often noticed this fact with surprise,
especially on a fine bright night, when the chorus of
song seemed to be carried on through the night, with
very little cessation, increasing in liveliness as the
early morning dawned, causing one to remark that
the birds sang all night as well as all day long.
Some four years since, about the months of May or
June, many people visited our neighbourhood (New-
castle, Staffordshire), to listen to the sweet music of
the various birds singing far on in the night ; among
which was one of the warblers, whose note was so
sweet that it was mistaken for a nightingale. The
latter bird has rarely been known to come so far
north. — E. Edwards.
Cucumber and Black Beetles. — In reply to
Mr. Smyth's question, as to whether the peel of the
cucumber destroys as well as alluies the beetle, I
venture to remark that it does both. Some members
of my own household have tried the experiment ; the
smell of the cucumber peel allures the beetles, and
after eating it they die almost directly, some close to
the peel, others as they are moving away from it, to
retire in their holes.— E. Edwards.
What is the Whipultre (Science-Gossip,
No. 160, p. 95). — I do not think Chaucer's "Whip-
ultre " has ever been satisfactorily identified, and I
can only make a very diffident suggestion as to the
species meant. In some dialects the cross-bar from
which horses pull a plough is called a " whippletree,"
and these are generally, if not always, made of ash.
It is possible, therefore, that the whipultre is the ash ;
and it might be so called because whipple-trees were
made from the wood, or the instruments might be
named from the tree of which they were made. This
view receives confirmation — very slight, it is true —
from the fact that whilst most of the more common
trees are mentioned by Chaucer in the passage indi-
cated, the ash is omitted from the list. The Cornel-
tree (Cornus sangninea) has been suggested, but I do
not know on what grounds. — Robert Holland, Norton
Hall, Runcorn.
Fluid for Strengthening Bones, . 10-lineaia, might have their
existence shortened without cause. — JV. Andrezvs.
The Song Thrush and Missel Thrush.—
Mr. Ingleby asks if it is not an unusual occurrence to
find the Missel Thrush {Tardus viscivorus) nesting
on the top of a wall. It is certainly an unusual oc-
currence ; but it should be borne in mind that birds
frequently build in strange places, and mostly from
necessity. The Missel Thrush loves to build in gar-
dens, shrubberies, and orchards, though at other
times it is a wild and shy bird. Possibly the owners
of the nests referred to by Mr. Ingleby could not find
suitable nesting-places in trees or bushes, or their
previous nests may have been plundered by prowling
-cats, who destroy many nests of young song thrushes,
blackbirds, and missal thrushes in gardens. The
birds, no doubt, finding they could not keep their
young from cats or vermin in their ordinary nesting-
places, finally built their nests on the top of a high
wall, where, it is to be hoped, the parent birds
succeeded in safely rearing their broods. In my
district, where there is little shelter fpr the early
breeding birds, blackbirds and song thrushes some-
times build their nests in stone walls, and in the roofs
ofopenhaysheds. "G. S.B." has fallen into a singular
mistake. He intimates — though his statement is not
over clear — that he has discovered a Song Thrush and
Blackbird mating together, and rearing, we must sup-
pose, a hybrid brood. Had he described how the
nest was constructed, the question might easily have
been settled. The eggs with "claret markings " were
undoubtedly those of the Missel Thrush, and the
female which he saw hatching, and which he states
was a Song Thrush, was, no doubt, a female Missel
Thrush. If "G. S. B." cannot distinguish between the
eggs of the Song and Missel Thrush, he would easily
jump to the conclusion that the female Missel was, as
he states, the Song Thrush. The nest, which he has
not described, would be lined with dry grass or hay,
if the eggs found therein had "claret markings."
The eggs of the Song Thrush are blue with black
blotches, densest at the thickest end ; though I have
several Song-Thrush eggs in my collection which have
not a single speck of black upon the blue. The nest
of the Song Thrush has always an inner lining of
hardened clay or cattle-droppings, while the nest of
the Missel is invariably lined with dry grass. This
latter bird is a very early breeder. His favourite
nesting site is in the fork of a tree, not often very
high up. I have seen the nest of a Missel Thrush on
the bare branch of a tree projecting over a public foot-
path, and the nest was so conspicuous that it was
plainly vi-ible at least twenty yards off. The Missel
is our largest song-bird, and though in colour and
markings it is not unlike the Song Thrush, yet it is
much larger. The cock bird commences to sing very
early in the year. In stormy weather it sings best,
and on this account the Missel Thrush is called the
"storm cock" in many parts of the country. The
nest and eggs described by " G. S. B." are those of
the Missel Thrush. This correspondent also seems to
believe that the Blackbird and Song Thrush breed
together. Such an unusual occurrence, so far as I
know, has never been recorded by any naturalist ;
and " G. S. B. " cannot be wrong if he describes the
eggs in his cabinet as those of the TitrJits viscivorus —
viz. the Missel Thrush. If he is still in doubt as to
the identity of his eggs, if he will send me one in a
small box, I will name it correctly and return it. At
the same time I have no hesitation in asserting, from
his description of the nest and eggs, that they are
those of the Missel Thrush. — H. Kerr, Bacup, Lanca-
shire.
Aquarium for Microscopic Work. — As two
or three of my friends, with myself, are anxious to
construct a small domestic aquarium (say about thirty
inches in length), for the purpose of keeping in stock
objects for the microscope, will you or any of your
contributors to Science Gossip kindly supply us
with information how to make one — size, shape, and
material, &c. ? I feel certain our thanks, with those
also of many of your readers, would repay you or
them for your kindness. — W. D. B.
" Gooseberry. — Dutch, Kruis berry, Cross-berry,
from its triple spines forming a cross."
NOTICES TO CORRESPONDENTS.
To Correspondents and Exchangers. — As we now
publish Science Gossip a week earlier than heretofore, we
cannot possibly insert in the following number any communi-
cations which reach us later than the 9th of the previous
month.
M. R. D. — Your species are as follows : — No. 1. Filago
minima. No. 2. Filago germanica. No. 3. Filago spatludata ;
the last species is much more unfrequent than the first two.
No. 4. We should not like to name anything from single leaves.
No. 5. Mgopodium Podagraria; L. No. 6. Angelica syl-
vestris; in future dry them a little before packing them for
post, they are then much more easy to determine, because they
travel in a better state.
J. C. (Hels ton). —Thanks for inquiry. Your parcel, No. 2,
has been sent.
A. W. Rosling.— The only Flora of the Isle of Wight we
can advise you to purchase is Bromfield's " Flora Vectensis."
This is both a valuable and reliable work.
F. H. A. (Fishbourne). — We have several letters expressing
the interest felt in " Botanical Work for April." You are quite
correct. No. 1. Viola Reichenbac liana; a very characteristic
specimen. No. 2. Draba brachycarpa. Look out for Ranun-
culus ficaria, and its varieties ; yours is a good locality
for it.
B M. W. (Hentland, Ross).— The specimens are, as you
judge, Micro-fungi. No. 1. Trickobasis Geranii, or Geranium
Rust. We are unable to detect any perfect fungi on No. 2.
perhaps you would send another example when more mature.
Science-Gossip Botanical Exchange Club.— Amateur
Botanical Collectors wishing to join the Club this year, should
as early as possible state their wishes. To save the promoters
from any loss, a small charge of say five shillings will be made ;
this may be remitted when the parcels are sent in October.
Rules to guide our members will be sent in May to those only
who announce their names. The Rules this season will con-
tain the numbers of species particularly wanted : these numbers
will correspond with the London Catalogue, 7th Edition, pub-
lished by Hardwicke & Bogue, post free, sevenpence.
M. R. D.— The Poison Ivy is the Rhus Toxicodendron. \ ou
must not, however, confound it with our "rare old plant,-' the
English Ivy, which is Hedera Helix. The Rhus is used as a
remedy for paralvsis, but we do not know the results.
S. A. B. (Allan, Dungannan).— The specimen enclosed was
Disandra prostrata.

HARDWICKE'S SCIENCE- GOSSIP.
D. S. — The leaf-like excrescences are not a fungus, but a
gall.
X. — We are not aware that any book has been published on
sea-side pebbles except that of J. G. Francis, called " Beach
Rambles," which is as full of geological errors as it could pos-
sibly be.
B. Hooker. — Your larva of the goat-moth should be kept in
a tin or wire-gauze box, and a large piece of half rotten ash-
wood placed with it. It will appear as a moth the third year
from its commencing its life as a caterpillar.
D. Cooper. — There is no doubt your specimen is Clausilia
laminiata, in which the mouth is almost entirely deflected to
the side opposite to that on which it is usually found.
R. Ramsay. — You will be able in your subsequent geological
reading to answer your own difficulty better than we can in the
short space at our command. But we may say that the reason
why it would be futile to bore for coal through the Oolite or
Wealden would be on account of the known thickness of the
overlying formations. 2nd. Your highest Scotch mountains
have nothing to do with the thickness of our old red sandstone.
The thickness of the latter is known from observing the angle
of the dip of the strata, and the area covered by the outcrop. If
you study Page's " Geology," you will soon get over your
present difficulties. Persevere !
A. Sells. — Your Zoophytes are : No. 1, Flustra foliacea.
No. 2, Sertularia operculata. No. 3, Dasya coccinea, a sea-
weed. No. 4, Sertularia argentea. Nos. 5 & 7, Sertularia
filicula. No. 6, Plnmnlaria falcata. No. 8, Antennularia
antennina.
A. Wheldon. — You will find full instructions for " sugaring"
for moths, &c, in " Collecting and Preserving Natural History
Specimens," published by Hardwicke & Bogue, 192, Picca-
dilly, at 3s. 6d.
A. G. N. — Your specimen is an English plant, usually found
growing in such localities as that you name. It is the curious
Butcher's Broom (Rnsciis acnleattis).
J. W. N. and Others. — It is intended to revise the rules, &c,
of the Botanical Exchange Club. Due and full notice of revi-
sion, &c., will be given in our columns. Application for mem-
bership can then be made.
W. Hobbs. — Very likely your chrysalides will develop early
during the coming summer.
J. P. Thompson. — We understood that a new edition of
Pritchard's " Infusoria" was postponed. Lownde's 'Anatomy
of the Blow-fly " can be had of Messrs. Hardwicke & Bogue.
R. B. N. — The fossils are corals, belonging to the Silurian
formation. No. 1 is the "Chain-coral" (Halysites catenipora),
and No. 2 is Favosites Gothlandica. The small shells which
you think look like "cockles" are in reality not bivalves, but
specimens of Melluscoidea. They are fossils belonging to a
group (Brachiopoda') once as abundant as they are now rare.
The name of those enclosed is Rhyconella IVilsoni.
T. McGann. — Your entomostracans are the male and female
of Canthocamptus minutns. Your slides are very well got up
indeed.
A. S. A. — Get " Collecting and Preserving," published by
Hardwicke & Bogue, 192, Piccadilly, price 3s. 6d., and read
the article on collecting butterflies and moths, by Dr. Knaggs,
and beetles, by Mr. E. C. Rye.

THE HABITS, FOOD, AND USES OF THE EARTH-WORM.
{Lumbricus terrestris. )
BY PROFESSOR PA LEY, M.A.
F there is a creature of
tolerably large size
which one would be
disposed at first sight
to place lower than
most others in the scale
of creation, it is the
common lob - worm.
To an unobserving eye
a very simple organism
without any particular
head or tail, and possessing only a slightly rough and
bristly body of tubular form, composed of contractile
rings — from which the class it belongs to is called
arinelidae— it is regarded by most people as a rather
ugl>'j but harmless, wriggling thing, slimy and disagree-
able to touch, unsightly to look at, and about as
destitute of interest as anything that lives and moves
and has an independent existence. But all this is
founded on a false estimate, and the false estimate
is, as usual, founded on ignorance. The lob-worm
may almost be called a clever and intelligent creature ;
very shy indeed of letting its mode of action be seen,
but showing by certain results, which readily come
under our observation, that it has instincts which fall
very little short of reasoning and design. And yet
this creature has "no eyes, nor any other organs of
special sense that are known."*
There are difficulties in ascertaining the habits of
the lob-worm, first, from its timidity and watchful-
ness, next, from its rarely appearing on the surface
except at night, thirdly, from its operations being
conducted almost entirely under ground. It is im-
mediately conscious of the tread of an approaching
foot, or of the least tremor of the earth, such as is
caused by digging or any garden-work. In these
cases it acts in two apparently opposite ways. If a
stick or a spade be thrust deep into rich garden-soil,
in which large lob-worms generally abound, and
moved to and fro, several of them will crawl out of
their holes, even at the distance of a yard, and wriggle
No. 162.

about on the surface. In this way the extraordinary
elasticity of the creature may be seen. It can stretch,
itself out to more than twice its natural length, and its
power of locomotion consists in its turnings and
twistings, its grasp of the earth by its short stiff
bristles, and by forming its head into a kind of hook
or anchor, and then dragging its body towards it.
But if, walking gently, and towards evening, you
chance to see a worm partly out of its hole, it will
immediately retire into it. Blackbirds and thrushes
may be watched pulling long writhing worms out of a
grass-plot, and devouring them; but if you walk
across the same grass you will not find a single one.
The reason is, that the light hop of the bird does not
warn the worm of its approach; the bird sees just the
head protruding, and by a dexterous clip and jerk he
extracts the delicate morsel, and bolts it whole — alive
and kicking.
The lob-worm has a singular habit of filling up the
entrance of its hole with fallen leaves, bits of stick or
straw, feathers, or any small and light objects — it is
rather fond of bits of string — that it finds near. If it
cannot get these, it piles up a little hillock of pebbles
or small bits of lime, cinder, &c. Why it does this
it is not easy to make out. Possibly it is to allow the
passage of air into the hole, and yet to prevent the in-
trusion of insects, such as beetles, or ants, which
would give it as much trouble and annoyance* as a
ferret gives to a rabbit in its burrow. For if it were
solely for purposes of food, which fallen leaves or seeds
of trees might be, and apparently are, the worm
would not draw in such indigestible delicacies as
string or feathers. Perhaps they pull in anything that
they find soft and yielding, and make trial of its
edible qualities at their leisure. Whatever be
the reason, the holes are carefully stopped up in the
way I have described. This seems, indeed, rather
stupid; because a knowing bird may regard the tufts
upon worm-holes as so many points for attack; but
* In Mr. Taylor's " Half-hours in the Green Lanes," a slug
{Tcstacelia haliotideci) is described as " the terror of the com-
mon earth-worm" (p. 211).
G

HARD 1VICKE' S SCIENCE- G OSS IP.
this is the habit of the creature, and as I once, and
once only, caught a lob-worm actually at work, I shall
describe what I saw, which I thought extremely
curious.
My attention was directed to the fact that if the
small heaps of pebbles were cleared away from a
worm-hole, they were sure to be replaced next
morning. Suspecting they worked only at night, I
went late one summer evening, after a shower of
rain, to a bed in the garden which was very full of
earth-worms. Walking up to it on tip-toe, and with
extreme care (for I was well aware that if it felt the
footstep two or three yards off, it would retire into
the hole), I was lucky enough to see one very big
worm with its body about half out of the hole. I
then stood for some time perfectly still, and watched
it as it reached out its elastic head to a small pebble,
and by a clever jerk, or possibly, by its slimy mois-
ture adhering to it, it drew the pebble to its hole
and left it close to the edge. Thus it took another
and another, and now I was able to explain what I
had often noticed, that every pebble within a circle
of about six inches was moved away and piled up
over the hole. The worm took the circle, elongating
Hs body, and moving east or west and to every point
of the compass, so to say, till not a pebble was left
within its reach. This I sate, and the reader may
believe that it is a strictly accurate account, though it
may seem to credit the creature with more intelligence
than it has any right to possess.
I believe the same may be seen by anyone who
will take a lantern into the garden late on a summer's
night, for they can hardly be conscious of light ; even
■of this, indeed, I have sometimes entertained a doubt,
though I cannot explain it in an eyeless creature.
Certain it is that on gently uncovering a pot of earth
containing a lob-worm, and bringing a candle to
examine it, when it happens to be above ground, the
creature will almost always immediately disappear.
But the feat which I saw performed is nothing to
what I am going to describe. I found on a gravel
path in my garden, and on the grass-plot adjoining,
a number of worm-holes, all stopped up with the long
narrow leaves of the weeping willow, which had
fallen in the late autumn, and had been placed erect
in small bunches. On examining separately a num-
ber of these leaves (of which each hole contained on
the average about twenty, though many of them had
more), I found, to my surprise, that every leaf had
the stalk-end uppermost, and the other end rolled
together into a kind of plug so as to fill up the hole.
Aery rarely indeed, perhaps in one or two out of
a hundred leaves, the creature had made a mistake,
and put the stalk-end downwards. But in these few
leaves the end was quite entire, whereas the leaf-
plugs in general seemed to have been nibbled or
partly eaten at the ends within the holes. Evidently
the stalk-ends were too tough, and the worm had
the extraordinary intelligence, blind as of course it
is, to find out by the touch the right and the wrong
end, and to make use of each leaf accordingly.
The mouth-end (so to call it) of a lob-worm has
many analogies to an elephant's trunk. It can curl
it and twist it, make it blunt or sharp, curved or
hooked, as it pleases ; and it is evident that an acute
sense of feeling resides in it. Therefore, recklessly
to chop worms in half with a spade, on the plea that
they do not feel, or to impale them on fish-hooks, is
cruel, even though we take old Walton's advice and
perform the operation "tenderly."
Worms feed by a kind of suction, as well as by
digesting vegetable fibre; they pass earth through
their long tubular stomachs, and eject it on the sur-
face in those little hillocks which we call worm-casts,
and which so much disfigure our closely-mown lawns,
till we flatten them down with the garden roller.
But these worm-casts perform more than one very
important function.
( To be continued. )
BOTANICAL WORK FOR JUNE.
IN taking our usual daily walk in the spring months,
we have often seen the Chickweed, Marsh Mari-
gold, and Water-blinks. We select these species
because they are so common as to be generally passed
over with the remark, "Oh, it is only the Chick-
weed," and so on.
Stay, however ; not quite so fast. The poor Chick-
weed, despised because it is so common, covers, with-
out doubt, three distinct species. As the result of a
careful examination, extending over twelve years, we
now regard this despised plant with deep interest,
and, at a glance, can detect the three species we now
lay before our readers : —
First. — The Stcllaria media, Linn., may be recog-
nized by the line of hairs on the stem and branches.
1. The true S. media, Linn., has five stamens;
petals invariably present.
2. S. Borceana, Jord., is devoid of petals ; stamens
three.
3. S. neglecta, Weihe. Sepals with long hairs,
often as long as the petals ; stamens ten. Note. —
We are unable to detect any good specific distinction
betwixt S. umbrosa and 6". neglecta.
Further. — No. 1 has showy flowers, with few
branches, about four inches long. No. 2 is a small
tufted plant ; branches very short ; flowers inconspi-
cuous. No. 3 is not unlike dwarf specimens of Stel-
laria nemorum, L. ; branches sometimes eighteen
inches high ; leaves large ; flowers large.
Our next species is the Marsh Marigold (Caltha
pahtstris). For many years we overlooked this
species, but now it seems like an old friend altered
by long absence. It is split up into three varieties ;
but we now only notice those which are common, or

Stems short and
tubercles on seed
a striking resem-
S terns long, soli-
of frequent occurrence, so as to throw a new charm
to our spring rambles : —
Caltha pahistris, L.
1. C. vulgaris, Schott. Flowers large, one and
a half to two inches across ; sepals meeting at the
margins ; follicles (seed-vessel) with a short beak ;
branches stout, very few.
2. C. Gtterangerii, Boreau. Flowers numerous,
very small ; sepals spreading ; follicles with a long
beak.
No. I is generally found in swampy situations ;
No. 2 in brooks, &c.
Another plant is often overlooked, the lowly
Blinks.
Montia fontanel, L. In this instance new names
have been introduced to distinguish each separate
plant.
No. 1. — ill. minor, Gmelin.
tufted ; flowers inconspicuous ;
with a raised point. This bears
blance to Stellaria Boraana, Jord.
No. 2. — M. rivnlaris, Gmelin.
tary, thick and flaccid ; tubercles on seed with flat-
tened point.
We regard No. 1 as a very distinct species ; it alters
not in a state of cultivation, but is rather rare in the
northern counties.
"Who does not recognize with feelings of delight
and joy the pretty Milkwort? {Poly gala vulgaris,
Linn.) Probably no British species has been split up
more frequently, if we except the Rubi. After years
of toil in looking up these sub-species, and after
examining, may be, thousands of specimens, we
have come to the conclusion that the so-called P.
z'ulgaris, as originally described by Linnaeus, includes
two well-marked forms, as follows : —
No. 1. P. vulgaris, L. Racemes, many-flowered;
leaves scattered, lanceolate ; branches numerous, as-
cending.
No. 2. P. depressa, Wend. Racemes few
flowered ; flowers small, white or pink ; leaves often
tufted below, or crowded thickly on the stem just
beneath the flowers, becoming opposite, all linear.
This is a pretty species.
There are other varieties, such as oxyptera, gran-

THE DATE-PALM.
PHGENIX DACTYLIFERA is the name given
by Linnaeus to this very important member of
the vegetable kingdom. PJicenix is the Greek name
of the date, and is probably derived from Phoenicia,
whence the best dates were brought. Its origin, like
that of so many of our cultivated fruits and vege-
tables, is unknown, but it may reasonably be sup-
posed to be a native of Arabia and Persia. In very
ancient times it was cultivated in Egypt (in the
Museums of Economic Botany, Royal Gardens, Kew,
is a specimen of "mummy bread" which is appa-
rently made of dates, such bread being frequently found
in jars in the tombs at Thebes) and in North Africa,
from which countries it was introduced very long after-
wards, probably by the Arabs, into South Europe.
It is a noble tree, attaining under favourable condi -
tions a height of from 60 to 100 feet. The stout
stem, which is very rugged, owing to the persistent
bases of the decayed leaves, is surmounted by a large
head of feathery leaves, 12 to 20 feet long. The
flowers are produced on large branches, which spring
from the axils of the leaves. Each inflorescence is
at first enclosed in what is called a spathe, which
afterwards falls away. As many as 10,000 flowers
have been counted in one spathe, and, as one tree
will produce many spathes at a time, some idea of
the total number of flowers may be obtained. Each
tree bears flowers of one sex only ; therefore cross
fertilization is necessary. It is said that in times of
war the Arabs cut down the male dates belonging to
their enemies, the result being of course a total
failure of the date crop. In " Hortus Collinsonia-
nus," occurs the following memorandum: — "At
Berlin was a large date-palm, at Leipsic was another,
which was the male ; both made attempts to produce
fruit, but imperfect, as these trees are of different
sexes, the Berlin tree being the female; anno 1749,
they married the two trees by carrying a branch of
male flowers and impregnating the Berlin tree ; and
then it produced good fruit, from which young trees
have been raised, but this espousal must be done
annually."
To the inhabitants of many countries the import-
ance of the date-palm cannot be over-rated. The
pulp of the fruit serves them and their various do-
mestic animals for food ; and even the extremely hard
and apparently useless stones are ground and given
to their camels. The young undeveloped leaves are
eaten as a vegetable ; in a mature stage they are made
into bags, and are the sole material used in con-
structing the huts of the common people. The stalks
of the leaves, when softened by boiling, serve as food
for camels ; and numbers are imported into this
country for the manufacture of walking-sticks. From
the stalks also, excellent baskets and crates are made.
Timber for the houses of the better class is obtained
from the stems, which also furnish an inferior kind of
sago. The fibre, called " lif," from the bases of the
old leaves, is converted into ropes and a sort of
coarse cloth. The heads of trees not bearing freely
are cut off, and the trunks scooped out. Into the
hollows thus formed, the sap rises at the rate of
from three to four quarts a day ; this quantity is kept
up for one or two weeks, after which it gradually
diminishes : in six or eight weeks the trees become
quite dry, and are used either as timber or firewood.

It is very probable that the palm-branches carried
before Christ on His triumphal entry into Jerusalem
were the leaves of this tree. Various branches of the
Christian Church, by their use of date-palm leaves in
decorating their churches on the anniversary of this
event, and the Jews, by their use of them during the
Passover, uphold this idea. For these purposes vast
numbers of trees are cultivated, especially in the
neighbourhood of Bordighiera, on the Sardinian
coast. Collinson says, " Mr. Bowles writes me . . .
the upper branches they tie up to turn yellow, and
then sell them to adorn churches and houses to
keep away the devil ; they have the art of managing
them."
Without the date the Sahara would be uninhabitable.
In every spot where there is any water this tree
flourishes, furnishing shelter to the traveller from the
fierce tropical sun, and food for himself and camels.
Very many varieties, differing much from each other
in colour, size, and shape, are cultivated, each known
by its own particular name. Some travellers mention
as many as forty-six ; and twenty-six distinct varie-
ties are exhibited in the Kew Museum. The date
is fast disappearing from the Holy Land, where at
one time it seems to have been very abundant. Moses
refers to Jericho as the " City of Palms," and we
have the testimony of Pliny in his Natural History
that palms abounded in Judea and the surrounding
regions. On several of the coins of Titus, Domitian,
and Trajan the country is represented by the symbol
of a palm-tree.
Formerly dates were credited with many medicinal
virtues. In some old herbals a decoction in red wine
is recommended for the piles. The date's prevailing
qualities are nutritious and saccharine. One pound
of dates might produce about one ounce of the dry
nitrogenous substance of muscle or flesh.
In conclusion, we may observe that the date-palm
may be seen growing in many collections in this
country, notably a very fine specimen in the large
conservatory at Sion House, the residence of the
Duke of Northumberland. In the Palm House at
Kew there is a much smaller one with an abundance
of a parasitical fungus on its leaves. This fungus,
which bears the name of Graphiola phanicis, and
seems partial to P/ianix dactylifera, attacks several
other species of the genus. Geo. Nicholson.
A LESSON FROM A FAGGOT-STICK.
THE object of this short paper is to show what
pleasure may be derived by the observer of
nature, from the contemplation of the most unlikely
and commonplace objects, and how numerous are
the sources from which instruction may be gathered
to serve as a lesson in entomology.
Those who are happily acquainted with this part
of Kent, to whatever county they may belong, and
to whatever part of the world they have travelled,
or may hereafter travel, will gladly confess that it

possesses points of beauty and interest which are not
easily surpassed by those of any other county, and
which entitle it to a place in the memory as a county
of singular beauty, well deserving the appellation
it has gained, "The Garden of England." Its
graceful swelling hills are everywhere mantled with
woods, sepia-tinted in winter, emerald -green in
spring ; fuller, deeper, and richer-hued in summer,
and splashed with purple, gold, and bronze in
autumn. It would, indeed, be difficult to say at
what season of the year they are most attractive.

Many of these woods are devoted to the growth
of a kind of underwood for the sake of hop-poles,
faggots, &c. They are allowed to grow for a period
of about seven years, and are then cut down ; the
trees are lopped to within a foot or two from the
ground. This frequently-repeated act of cutting down
causes the stumps to assume the most fantastic and
picturesque appearances. They are often decorated
with an elegant drapery of clematis, ivy, black
briony, briony, and other climbing plants, and the
graceful polypody hangs its waving tufts from their
wrinkled sides. Among the trees so grown may be
enumerated the horn-bram, hazel, chestnut, ash,
white-bram, oak, cherry, maple, &c, so that the
woods present considerable variety to the wanderer.
Beneath their shade grows a great selection of wild
plants, decorating the earth as with a coloured
carpet. During April these woods are gay with
anemone, primrose, cardamine, two or three species
of viola, and the golden pilewort ; while a little
searching discovers beautiful cushion-like masses of
Adoxa vioschatcllina, the tropical-looking spurge-
laurel, with its hanging clusters of yellow-green
sweetly-scented bells. The curious, unhealthy-looking
Lathrcza squamaria, growing from the roots of the
hazel, and other trees, upon which it is parasitic,
trailing branches of ground-ivy, and the sweetly
pretty Oxalis acetosella.
The faggots brought to our doors for lighting fires
contain specimens of all the trees above mentioned,
and many an interesting botanical lesson may be
gathered from their examination. The nature of the
bark, the formation and arrangement of the buds,
the peculiar scars left by the falling leaves, and other
points, may be well studied from these. When winter
winds are howling round, and torrential rains are
drenching the earth, we may well fly to the study of
such objects as these for recreation and instruction.
About the end of the month of June I had occasion
to hunt through one of these faggots in search of a
stick for the amusement of one of my children. I
picked up a straight branch of ash, which appeared
just to suit my purpose, and commenced to cut and
trim it. To my surprise, although looking perfectly
fresh and sound, I found the bark almost completely
separated from the wood below, and the space between
the two filled with a fine sawdust-like powder.
Fixing my attention a little more closely upon the
twig, I now noticed that the bark appeared as if
riddled with small shot, as shown in the upper part
of fig. 85. On stripping the bark, and blowing away
the dust alluded to, I detected a groove, originating
below a leaf-scar, which, after passing under the scar,
branched off in opposite directions, as seen in fig. 85.
Springing from these grooves were now clearly
discernible a great number of shallow channels, sepa-
rated from each other by the merest film of wood ;
each channel widening out in proportion to its dis-
tance from the main groove. At the end of each of
these branching channels I found a small, fat, active
little grub busily engaged extending its passage, the
wood forming its food. I now, of course, saw at a
glance the meaning of all this loose dust and apparent
rottenness, and the origin of these main and lateral
canals. It appeared quite clear that the main ducts
were made by some insect, that eggs were deposited
at minute intervals, on both sides of these tracts, that
these eggs were finally hatched out, that the grubs
so resulting immediately commenced feeding, tra-
velling continually away from the centre, and that as
they waxed in stature they necessarily enlarged their
tracts.
Having proceeded thus far in my discoveries, and
126
HARDWICKE'S SCIENCE-GOSSIP.
my interest being thoroughly aroused, I determined
to prosecute my search. For this purpose a number
of ash-branches were selected, and carefully laid on
one side. A cursory glance at these showed nothing
at all abnormal or noticeable, but a more careful
examination disclosed a number of small ridges of
discoloured skin traversing the branches in various
directions. Taking off the bark at these points, the
main passage before-mentioned was exposed to view.
On tracing this up or down the stem it was always
found to terminate below an old leaf-scar. Finding
this, I now examined the leaf-scars, and in a majority
of cases found a small hole filled below with fine
dust. Detaching the skin at this point a small run
was visible, passing just below the scar to the right
or left ; and when clear of it branching off in two
opposite directions up and down the branch (fig. 89),
but usually more or less spirally arranged. At the
entrance to this passage was generally found a small
beetle, and another some distance along. There
were mostly two, but whether they were male and
female, or whether they were both females acting in
concert I was not able to determine. The diameter
of the principal passage is about i-i6th in. The
beetle I found to be Hylisinus fraxini.
It appears to be very prolific, and must be very
destructive to the trees it attacks. In the cases I
examined there were usually from 60 to 80 diverging
passages, and at the end of each, as before-stated,
was a fat larval beetle, busily engaged excavating for
its daily rations. In many branches, almost every
node was the starting-point for these channels, and
the amount of mischief done to the tree may well be
imagined when we bear in mind the numbers found
in each run, and their method of working side by
side so closely as to all but completely sever the bark
from the wood. After examining a great number, a
few specimens were put on one side for the purpose
of watching their progress towards maturity.
On the 28th August the now-transformed larvae
began to emerge in the imago form, i.e., as perfect
winged beetles. They were pretty little insects,
varying considerably in colour, some being much
lighter than others, and most distinctly clouded.
On raising the bark I found a great number still
occupying their snug quarters, where they had fared so
comfortably during their early days, and where they
had undergone their final change preparatory to
entering upon a more active and greatly extended
sphere of action. I now found that, prior to under-
going their first metamorphosis, i.e., assuming the
pupa form, they sink for themselves, at the end of
their respective galleries, a comparatively deep pit, in
which the change takes place. In these pits they
may be found in August ready to make their way out
previous to setting up housekeeping on their own
account.
Noel Humphreys gave an interesting account of
these beetles in the pages of the "Intellectual Ob-
server," in 1862. He there states that they attack
the elm as well as the ash, and that their ravages are
often terrible. The ash, however, is their favourite
tree, as may be gathered from the specific name
{Fraxini) of the insect.
Having thus learnt how numerous and destructive
these insects are, and remembering that in a row of
ash-trees that I passed daily some were flourishing
grandly while others were dead or dying, I determined
to ascertain whether these beetles had anything to do
with the matter. On examining the dead and dying
trees, I found them literally riddled with minute
shot-like holes — the significance of which was now
only too plain to me. I had often noticed the dif-
ference between these trees, whose conditions, as to
soil, climate, &c, appeared to be identical, and
wondered what could be the cause of the death of
these, while those by their side grew vigorously.
Had I noticed these holes a few weeks earlier, their
meaning would have been hidden from me, but now,
from the study of a few faggot-sticks I was able to
understand most clearly what had been going on
beneath the bark of these unfortunate trees, and why.
they had gradually, without any apparent cause,
drooped and died, branch by branch and limb by
limb, until a giant mass of mere dry sticks remained,
rearing its weird and awe-inspiring form against the
sky.
Thus, from the careful examination of a " faggot -
stick " I gathered the life-history — or at all events the
leading facts in the life-history — of a pretty little
British beetle, which undoubtedly plays an important
part in the "struggle for existence," which ultimately
results in the "survival of the fittest," that has to
compete in common with every other member of
the organic world.

WHAT A DIATOM IS.
( Continued from page 107. )
IT is the act of generation that brings back the
normal size of the frustule, already reduced in
dimensions by repeated deduplications ; if this did not
take place, the diatom would (theoretically) at last
become a mere atom — a circumstance which never
takes place.
The act of generation, properly so called, may be
said to consist in all organisms of a simple amalgama-
tion of two more or less distinct particles of proto-
plasm. The diatoms are no exception to this rule,
and with them this union comprises either the contents
of two distinct frus titles, or of differentiated protoplasm
contained in a single frustule. This phenomenon is
called the conjugation of the Diatomaceaa. The
study of the phenomena of conjugation in some forty
species of diatoms, by various distinguished microscopic
observers, has not furnished us with such complete
HARD WICKE >S SCIENCE - G OSSIP.
127
results as we might desire, and the greatest circum-
spection is necessary in the interpretation of the facts
observed. That which we appear to know for certain
is that conjugation takes place in diatoms, and that
the material result of this is the formation of what is
called a sporangium. This proceeds either from the
condensation of the protoplasm and endochrome con-
tained in the interior of a single frustule, of which the
valves are separated in such a manner as to enlarge
the internal capacity of the frustule, the matter thus
amassed giving place, according to the species, to the
formation of one or two bodies, more or less round or
oval ; these very soon secrete on their surfaces a hard
shell (test-resistant). These are the Sporangia, or
the intimate union and fusion of the protoplasm of
two contiguous frustules that have partially opened
along the sections of the connectives for its liberation.
Here also is formed, according to circumstances, one
or two sporangia. When the sporangium [is pro-
duced by a single primitive frustule, it is probable that
the original primordial utricle, which was already pre-
viously divided into two for the purpose of deduplica-
tion before the secretion of the new siliceous valves,
and that the sporangium, formed of the differentiated
protoplasm, produces that of the two young utricles.
This, however, requires to be verified by direct obser-
vation. In both cases there is promptly developed in
the interior of the sporangium a special body, which
varies in form according to the genus, which grows
rapidly, and which possesses an envelope rich in
silica, and is able to resist calcination and the
action of concentrated acids ; it is often wrinkled
across the external surface ; this is the Aitxospore.
This last is the analogue of the zygospore of Zygne-
maceae. Its growth at last bursts the sporangium,
and carries with it to its apices, the two halves of the
sporangium-like little caps.
"When the auxospore has attained a size generally
double, or even more, of the frustule that has origi-
nally produced it, we discover in its interior, lying
across the envelope, the valves forming the new frus-
tule. These last are apparently the product of a true
generative act, and which we are justified in consider-
ing for the moment as sexual, although our means of
observation up to the present are much too imperfect
to permit of our being able to distinguish the male
from the female element in the products of conjuga-
tion. The first frustule is called the sporangia! frus-
tule. With this is destined to commence a new cycle
of vegetative generations by deduplication, which
continues up to the moment that a new conjugation
takes place. It restores also the normal size of the
frustules degenerated by the repeated deduplications,
and we see here the singular phenomenon of the child
being at its birth much larger than its parents. The
sporangial frustule is always enormously large in com-
parison with its parents, the empty valves and con-
nectives of which are generally retained by a mass of
gelatinous matter secreted previous to the act of con-
jugation. We believe that other modes of reproduc-
tion exist in the diatomacea? beside that of conjuga-
tion, but the biology of these little beings is much too
imperfect to enable us to hazard any profound hypo-
thesis on this subject. It is evident that all the
frustules do not finish by conjugating ; this is highly
improbable, when we consider the rarity of that
phenomenon. Some other explanation is necessary
to account for the variations in the dimensions we
meet with in the different individuals of the same
series other than that of deduplication, as without it
those frustules that escape conjugation would go on
diminishing in size indefinitely, and we know from
observation that every species of diatom possesses a
maximum and minimum of dimension which it never
passes.*
The rapid appearance of species where they did not
previously exist — their periodic succession at deter-
mined seasons, and which we had never been able to
find in the intervals in the same locality — this presents
the possibility of a mode of generation which is only
yet suspected, by germs, by micro or macro-zoospores,
possibly even in the first case with the formation of
zygozoospores, as it takes place among many of the
inferior algae who live under the same conditions as
the diatoms.
We enter here a field of study of the greatest interest
and novelty to every naturalist furnished with a good
microscope, and possessing time and patience neces-
sary for such researches, and we dare affirm that any
member of a microscopical society who shall follow
with care the entire life cycle of a single species of
diatom, even the commonest, will probably render a
greater service to science than if he had described and
figured hundreds of frustules from the four quarters of
the globe.
Note. — In a communicationf to M. Deby, Professor
H. L. Smith makes the following remarks : —
' ' I have received your brochure, entitled, ' Ce que
c'est qu'une Diatomee,' for which I thank you. What
you say is generally correct. I have myself published
a part in the 'Lens' in 1873, but I entirely differ
from you on certain points. The communication
which you say exists between the internal protoplasmic
substance and the external medium does not take
place, as you say, along the sutures of the connective,
but in the naviculus, properly so called ; it exists along
the raphe or median line, and in the Nitzschias and
Surirellas along the ala? and carina?. (This is an in-
teresting confirmation of Ehrenberg's observations,
who had also studied this phenomenon many years
before J. D. ) I possess drawings showing the injec-
* The process of self-division, no doubt, gradually exhausts
the vigour of the sporangial frustule, but this power is possibly
retained longer by some individuals than others (thus bearing
a striking resemblance to parthenogenesis in the Aphides, &c),
but there is probably no fixed limit. I have seen much smaller
valves of A ulacodiscus Kittoni in a New Zealand gathering
than in a copious and pure gathering from Vera Cruz. — F. K.

tion of indigo along the median line, and its penetra-
tion into the interior of the diatom, particularly in
Stauroneis kept for some days in indigo water.
Beside this demonstration, I was able, by the em-
ployment of the pigment, to obtain a glimpse of the
mode of progression in the large Pinnularias. I am
half tempted to send you my drawings. Many cases
of conjugation are not always so simple as is generally
supposed.
" When a large Pinnularia is observed in the field
quite blue with indigo, we see in side-view (fig. 90)
little particles of indigo running along the (X) raphe
as far as the end of the median line ; here they accu-
mulate into a little ball, at C. In fig. 90, (7 b,
a little ball is seen on each side, but that which is
most surprising is, these balls revolve on their axes.
When the ball acquires a little size it suddenly breaks,
and the particles sail off in the direction a e (fig. 91),
and a new ball is again formed ; this is on supposition

that the frustule is moving in the direction of the
arrow d. Moving the other way, the particles slip
down the other half of the median line or raphe, and
form a little ball, as before, at its end. I have
watched this for hours, and I can assure you that it is
a glorious sight. I had some magnificent large Pin-
nularias, and these effects were best seen when the
motion forward of the frustule was prevented by its
coming in contact with some particle of sand or dust.
The colour in the field was the ordinary indigo-blue
water colour, pretty thick. Furthermore, there
always appeared a gelatinous envelope which pre-
vented the actual contact of the indigo particles with
the frustule, which, as it moved forward, pushed them
in advance, as at d (fig. 90). The slightest applica-
tion of aniline red (Fuchsine) demonstrates the
external gelatinous covering by the absorption of the
colour, even before the colour is seen elsewhere in the
field, but this aniline instantly arrests all motion of
the diatom.
" The act of deduplication of the primordial utricle
is effected with great rapidity; it manifestly commences
at the two ends of the frustule at the points a and b
(fig. 92) ; the membrane there forms a fold, which is
gradually prolonged until it reaches the central
nucleolar mass ; this occupies about six minutes from
the commencement of the phenomenon.
" I have never been able to perceive a true circular
nucleus in Pinnularia major (Ehr. ), but it is very
visible in divers species of navicula, such as N. firma,
and in the Stauroneis. It is very manifest in the
Surirellas. The frustules only separate from each
other in seven days, rarely before. The conjugation
in the Pinnularias continues for four days before the
act is entirely completed. I have followed it step by
step, and measured with a micrometer the sporangial
development. ... I remain, &c,
"H. L. Smith."
(The above experiments are of great interest, and
will, I hope, be repeated by other diatomists.
The study of the living frustule has, I fear, been too
much neglected for that of the dead valve, the
diatomist having been seduced by the elegance of its
contour and the beauty of its ornamentation. If, as
Professor Smith describes, the communication with
the interior of the frustule is through minute apertures
at the termination of the raphe or median line, it is
evident that those forms which do not possess this line,
and are neither alate nor carinate, must possess some
other means of communication ; in the Aulacodisci
this may be by means of the processes which are
apparently perforate, but in the Triceratia, Coscino-
disci, &c, I think M. Deby's suggestion, that it takes
place at the margins of the connectives, is probably
correct. — F. K.)
Those interested in the structure of the diatom frus-
tule will find much valuable information in the papers
of Dr. Wallich, particularly that published in the
Monthly Mic. Jour., Feb. I, 1877. A paper by the
same author, entitled " Are the Desmids and Dia-
toms simple Cells?" will be found in the April part

A GLASS-EATING LICHEN.
ON visiting an antiquarian friend, to whom I am
indebted for the loan of specimens, &c, some
old stained glass of about the fifteenth century was
submitted to me, and an opinion asked as to the cause
of certain irregular worm-eaten-looking holes of some
depth, occurring generally only over one surface of the
plates. My friend informed me that it was publicly
discussed some twenty years ago as to its cause, for it
had often been observed in old glass windows. At

first, on carelessly looking at it, it appeared to be
explained by that disintegration which gives rise to
those beautiful iridescent scales on old glass, and
especially in the old black glass Dutch bottles, whose
surface, on removing the scales, presented somewhat
the appearance described. My friend informed me it
was considered by some to have been made by the

some dark green glass twice its natural size, which
shows the general arrangement. On submitting
them to microscopical examination, to my delight,
all the edges of these masses appeared to be spiked,
and, although they had been in my friend's possession
for thirty years, showed the cellular structure deline-
ated in fig. A (Hartnack, ob. 7, oc. 2, tube drawn
out), being the portion C of fig. B (Hartnack, ob. 4,
oc. 4, tube in). I have shown them to two botanists,
who are quite satisfied as to their nature ; but they
asked the question as to whether they might not be
lichens which had occupied already existing holes;
this, however, was capable of denial on the following
grounds. It will be observed in fig. D that the bodies
commenced to grow at certain points, but as they
became larger they also became confluent, forming
irregular masses with a serpiginous margin, to which the
depression in the glass always corresponds ; the central
portion of each depression is level, and however large
it may be, it is of the same depth, the steep edges

workmen, to give a better effect to the light ; but the
irregularity sets that question at rest directly, though
it stimulated me to look into the matter more care-
fully, and on a careful examination I was fully satis-
fied that each depression was occupied by a small
lichen, such as we see covering grave-stones ; at figure
being occupied by the growing processes which seem
alone to have the absorbing power ; and lastly, on
removing the growth by various re-agents, the exact
figure of the points and even in some instances of
the individual cells, are seen beautifully cut and em-
bossed upon the glass. It occurs on the side opposite,
and not on the painted side, which, in glazing, is
placed on the inside of the window, and therefore
would be unfavourable to the growth of these plants ;
neither does it occur round the edges, which are over-
lapped by the lead. One point was at first puzzling ;
these erosions sometimes appearing to run in straight
lines, as seen in fig. E ; it could, however, be de-
monstrated by a magnifying glass that it occurred
along old scratches, the rough surface of which had
afforded the most easy attachment for the spores and
young plant. It is to my friend, Mr. T. Coates
Archer, to whom I am indebted for the specimens,
and also for a few notes as to their history. They
are from the Church of Little Dunmow, in Essex
(celebrated for the annual distribution of a flitch of
bacon), from which it was removed by some glazier
of Felsted, from whom my friend bought it, and has
now had it over thirty years.

The remarks may at first appear to be of little
interest, but in putting them forward it is with the
hope that they will teach us to at least take pre-
cautions to protect or remove such an unpleasant
enemy from some of the most beautiful works of
art. H. T. Johnston-Lavis,
ON PREPARING AND MOUNTING LEAVES
AND OTHER PARTS OF PLANTS TO
SHOW THE CRYSTALS IN SITU.
By W. H. Hammond.
EVER since I first began to use the microscope
Plant Crystals have been objects of interest
to me, not only on account of their great beauty as
"objects," especially with the polariscope, but also
because they open a new and comparatively unex-
plored region of phytotomy ; in fact, except in Pro-
fessor Gulliver's writings, they are hardly mentioned,
or very summarily dealt with by other botanical
writers. At first I used to be content with a sight of
them after boiling and mashing parts of plants, but I
soon became dissatisfied with this method, and began
to look about for some means of examining the
crystals just as they grew in the different plants ; for-
tunately I happened to look at a back number of
Science-Gossip (January, 1875), and came across a
paper by the late Dr. Beatty, " On Decolouring and
Staining Vegetable Tissues for Microscopic Ex-
amination " ; other papers, by Dr. Beatty, came out
afterwards, and I gathered many valuable hints from
them oh the subject.
I am often asked how my preparations are made,
so I will describe my process of preparing and
mounting, for the benefit of other workers with the
microscope who are interested in these beautiful,
but much neglected, marvels.
The first thing to be done is to get the bleaching
solution, and this may be very easily prepared as
follows : — Equal weights (say four ounces) of chlori-
nated lime and common washing soda, both in fine
powder, are put into a half-gallon bottle of cold
water, and well shaken together, then left to stand
till the fluid is quite clear, this is poured off gently
into another bottle, and a strong solution of washing
soda added as long as a white powder is thrown
down. The mixture is again left till clear, and then
poured off; this is the bleaching fluid. The original
substances in the first bottle may be again treated with
cold water. Leaves and other tissues are kept in this
fluid till bleached and semi-transparent, large or thick
leaves should be cut up into small pieces. I find the
small, round night-light glasses, which may be bought
for a penny each, are very convenient for bleaching
the tissues in, and also for the dyeing and subsequent
soakings, covering them over with pieces of glass to
keep out the dust. It is not always convenient to
prepare and mount leaves directly they are gathered,
so I always carry with me a small account-book,
interleaved with blotting paper, and with an elastic
band round it ; leaves are put into this when gathered,
and by carrying it in the breast-pocket of the coat,
they are soon dried by the warmth of the body ; in
the summer time several books full of leaves are col-
lected, ready for the long winter evenings. Dried
leaves will bleach sooner than fresh-gathered ones.
Having bleached some leaves (the time it takes to
do this varying very much), they must be well washed
in warm water in basins or pie-dishes, changing the
water often for about two days, and brushing the
tissues with soft camel-hair brushes. I often find it
of use to put the plant tissues into acetic acid and
water for about a minute before the final washing,
but acids must be very cautiously used, or the crystals
may be dissolved.
The leaves or tissues are then ready to go into
either of the following dyes : —
The carmine dye is prepared partly according to
Dr. Beales's formula, viz. : —
Carmine 20 grains.
Strong liquor ammonite ... \ dram.
Pure water 4 ounces.
The carmine is heated in a test tube with the am-
monia till dissolved, and then added to the water in
a bottle and well shaken, and left to settle or be
filtered. The dye should smell strongly ammoniacal.
Sections are soon dyed in the above, but leaves take
several days, or a week or more. Sections of the
India-rubber plant leaf, or of the common fig, dyed
in carmine, will show the stalked crystals, called
cystoliths, very nicely ; pieces of the leaves of the fig,
hop, nettle, wall-pellitory, or wych elm, dyed, will
show the cystoliths when viewed from above or
below. I generally mount two leaves or pieces on
the same slide, one with the superior and one with
the inferior surface uppermost.
The logwood dye is prepared according to the
prescription in Rutherford's " Histology."
A. Make a saturated solution of calcium chloride
in 70 per cent, alcohol, and then add alum to
saturation.
B. A saturated solution of alum in 70 per cent,
alcohol.
C. Add A to B in the proportion of one to eight.
D. A barely alkaline saturated solution of logwood
in water.
Add D to C till a deep violet-coloured dye is
obtained.
I make D by boiling logwood chips with water
and a very little potash, then filtering.
I generally use methylated spirit where alcohol i<
recommended.
The leaves and tissues may be immersed in either
of the above dyes, straight from the last wash-water,
and will be dyed in either in about the same time.

Tissues when dyed must be put into clean water, then,
if dyed with carmine, into acetic acid and water for
a minute ; if dyed with logwood they must be put
into alum and water, they must then be put into
two changes of clean water and brushed with
soft brushes. The remaining operations will be
described further on.
I also use a blue dye made by pouring six or eight
drops of Judson's aniline blue into an ounce of
methylated spirit, shaking and filtering. Leaves and
sections to be dyed in this must be soaked in methy-
lated spirit for about a day after being taken out of
the last wash-water. After dyeing they must be
washed and brushed in methylated spirit. Leaves
generally require to be kept in this dye for about
a week. Leaves and sections after undergoing these
operations may either be mounted in Deane's gelatine
medium or in dammar or balsam dissolved in ben-
zole. I like to have specimens of the same kind
of leaves dyed in all three colours and mounted both
ways, or only the blue-dyed ones mounted in balsam
or dammar.
Leaves or sections, which are to be mounted in
Deane's medium, should after the final washing, after
dyeing, be put into the following solution as recom-
mended by Mr. Deane, for two days : —
Rectified spirit \\ ounces.
Pure water 1^ ounces.
Pure glycerine 5 drams.
Take the tissues out of the above fluid, drain off as
much as possible and mount in the medium. I prefer
this way of mounting for most leaves and other
tissues, for this reason, it does not make them so very
transparent as dammar or balsam does, and generally
every cell-wall is distinctly seen, the crystals in the
cells, the hairs, and every other part of the leaf.
Leaves to be mounted in dammar or balsam should
be thoroughly dried from the last washing, after
dyeing, this is best done by putting them into one of
the before-mentioned interleaved books, and carrying
in the pocket for a day or two. When thoroughly
dry take them out and put them into a small wide-
mouthed bottle, pour over them benzine enough to
cover them, and cork up tightly till perfectly trans-
parent. When ready to mount, take the leaves out
of the benzine, drain, but do not dry them, and
mount quickly in balsam or dammar dissolved in
benzine (benzine collas is the best benzine to use).
Leaves mounted in this way are beautiful objects
for the micro-polariscope, if they contain crystals or
have hairs upon them, but they are nearly always
so transparent that the cell-walls are quite ob-
literated.
Good leaves to experiment upon, for sphreraphides,
are Chickweed, Mercury, Wild Strawberry, and
many of the Rosaces.
For long crystal prisms — the outer skin of the
Gladiolus Bulb, Onion, Shalot, and Garlic.
For short prismatic crystals— Clover, Sanfoin,
Beech, and Trefoil.
For true raphides— Squill Bulb, Hyacinth, Blue
Bell, Lemna Trisulca, Balsams, Willow Herbs,
Fuchsias, and Arums.
Cystoliths. — Leaves containing these should not
be mounted in balsam or dammar, as they do not
polarize, and are generally rendered quite invisible
by this way of mounting.
No one need be afraid of not being able to procure
specimens, for I believe the greater part of our plants
contain crystals of one kind or other ; they may be
well and easily studied by mounting in Deane's
medium after preparing and dyeing, they may also
often be very well seen by simply bleaching, washing,
and examining in water. And I may add that the
crystals afford an abundance of beautiful materials
for the microscope, and that the more they are studied
the more they will be admired. Their taxonomic
and physiological significance too, is an important
subject for further research, concerning which, Pro-
fessor Gulliver has given the results of extensive
observations. He recommends boiling the plant
tissues in a solution of caustic potash ; this is an easy
way of exposing some crystals and their cells, though
by no means so effectual in the preparation of beau-
tiful and instructive slides, as the methods which I
have attempted to describe.
NOTES ON A DREDGING EXPEDITION.
BEFORE entering upon the subject of actual
dredging, it would, perhaps, be as well to give
a brief description of the little fishing-village which
formed my head-quarters. Rossbeigh is a small
watering-place on the east shore of Dingle Bay, in
Kerry, Ireland. It is the property of the Hon. Row-
land Winn, and consists of a few lodges, one of
which, in the month of September last, I rented.
About a mile away from these lodges are a few scat-
tered fishermen's huts ; and when the reader is
informed that Rossbeigh is eight miles from the
nearest town, and twenty from any railway station,
he will understand that I had greatly to depend upon
my own resources.
On looking at the map of this district, it will be
noticed that there is a long spit of land running out
towards a place called "Inch": this spit is over
three miles in length, and is entirely composed of
sand. From the signal-towers at the termination of
this peninsula to a point called Feaklecally, an ima-
ginary line may be drawn, and within this no great
depth of water can, I believe, be found, for the fol-
lowing reason : Rossbeigh is situated on a mountain-
side, a mountain whose base terminates upon the
seashore ; the soil at its foot is largely composed of
a conglomerate, containing a great quantity of rounded
r32
HA RDW1 CKE 'S S CIE NCE . G 0 SSIP.
stones, and formed, in all likelihood, by the conti-
nual detrition of the mountain-streams. This soil,
being so friable, falls an easy prey to the eroding
influence of water, the sea having made considerable
inroads into the land ; so much so, that a lodge which
about thirty years ago was occupied by Lord Headley,
is now entirely washed away ; its site being utterly
unrecognizable. Now the headland of Feaklecally
checks any currents running up from the Atlantic,
while the sandhills at Rossbeigh are another break-
water. Thus the bottom of the bay at this portion is
shallow, and largely consists of the rounded boulders
of the conglomerate. I have given this description
in order to explain the kind of sea-bed I had to work
pon. We will now proceed to the actual dredging.
The first requisite is of course the dredge and rope.
The former of the two consists of a strong iron frame-

work (if galvanized the better) ; the scrapers are two
in number, so that, no matter on which side the
dredge may fall, it can work. The rope is made of
good stout material, and ought to be "barked,"
which can be done in any tan-yard for a trifle. The
rope is attached to the dredge in a somewhat peculiar
manner ; the end is tied securely to only one of the
attachment rings, and with a piece of spun yarn the
other ring is whipped to its fellow ; so that, supposing
the dredge to have anchored on a stone, and that it
cannot be liberated by retracing ground, and thereby
reversing the strain on the dredge, the boat is pulled
rapidly until the spun yarn breaks ; then the dredge,
being capsized, is freed easily. The next item is the
boat : the heavier this is, within reason, the better.
In this I was, at the outset, unfortunate, as at first
I could only obtain one of the Irish native canvas
canoes, which, drawing but little water and keelless,
would, on the smallest provocation, perform a
rotatory motion, which would result in heading in a
totally opposite direction to the one started from ;
however, Mr. Winn very kindly had a small whale-
boat belonging to him repaired for me, which served
my purpose excellently. Across the boat, resting on
each gunwale, I had a board fixed, as a support for
the tray which received the contents of the dredge.
This little detail is a very useful one, as it not only
saves the trouble of stooping to examine the spoil,
but also prevents the giddiness which often attends
that position, and which is very frequently the herald
of sea-sickness. Three sieves, of varying meshes,
are also very useful ; one, a coarse mesh, of about
half-inch diameter ; the second moderate, about
one eighth-inch ; and the third of perforated zinc.
Their use will be afterwards explained. Also a shal-
low box as a receptacle for the contents of the
dredge, plenty of bottles, in which to store the

treasures, a gallon can of fresh water, a good strong
pocket-knife, a brass forceps and a pocket-lens com-
plete the equipment. The last I would recommend to
be slung round the neck, so that it may be free, as it
is neither an easy nor a clean task to be searching for
it in the pocket with wet and often slimy hands.
Now all being completed, dressed in your oldest
clothes, and legs encased in mackintosh leggings, the
boat is pulled out to the dredging-ground, and there
the dredge is thrown overboard, near the stern, on
the windward side, taking care that the rope runs
freely. When it touches the bottom, the boat should
be rapidly pulled until enough rope has been let out :
roughly speaking, there should be twice as much rope
out as the depth of the water dredged. When enough
is paid out, a turn or two should be taken round a
belaying-pin, and the inner end retained in one hand,
while the other should clasp the part outside the
boat, by which aid, the rope serving by its vibration
as a kind of telephone, the working of the dredge

i33
may be detected. If the dredge is jerking and
bounding, the boat is being pulled too fast, whereas,
on the other hand, too slow a progress causes the
irons to sink too deeply ; but when all is as it should
be, the hand feels a gentle quivering, which proves
the machine is working steadily. Do not, how-
ever, hold the rope too tightly, else, in the event
of the dredge being suddenly anchored by a stone,
you, in all probability, will collide rather unpleasantly
with the side of the boat. Should the dredge get
entangled, the best way to free it is to retrace
ground, and, in most cases, it will free itself on being
place in the tray. The process of sifting is greatly
facilitated by washing the top mass.
My first day's dredging off Rossbeigh was about a
mile from shore. This attempt was made from a.
native canoe, and from the little hold the craft had
upon the water, the dredge could scarcely be got to
work. The only benefit that accrued to me from
that day's work was a rough knowledge of the depth
of the water and the nature of sea-bottom, which,
unfortunately, largely consisted of heavy, rounded
stones. The next day's work was undertaken at low
tide. The course chosen was further out to sea ; but

towed in an opposite direction ; if that means fails,
the rope must be strained until the spun yarn, already
alluded to, breaks, when the dredge, being capsized,
will easily free itself.
Supposing all to have gone on well, after half an
hour the dredge may be lifted rapidly, but steadily,
to the surface, taking care to lift it clear of the side of
the boat, else you run the danger of crushing the
Crustacea and shells it may contain, and the contents
emptied into sieve No. I (the coarsest). Large
shells, stones, &c, are here retained, the smaller
specimens successively passing into sieves Nos. 2 and
3, and finally the very minute forms find a resting-
even at this distance from land (about 1 h mile from
shore), where comparatively deep water might have
been expected, the depth did not, I should judge,
exceed 5 to 7 fathoms, the dredge coming up choked
with Rhodosferms and other sea-weeds, mostly
Polysiphonia and Ptilota. However, on emptying
the dredge, a variety of marine animals were dis-
covered, which, although not rare, were none the
less curious. Two specimens of Pisa tctraodon
rather obtrusively first made their appearance, and,
were followed soon by what very easily might have
been mistaken for a lump of sea-weed, Stenorhyiichits
phalangium ; several specimens of the Hermit Crab-
*34
HARD J VI CKE >S S CI EN CE-GO SSI P.
( Pagurus Bernhardii ) were also inclosed. On more
closely examining some of the sea-weed, I found
several specimens of Caprella linearis, a most
grotesque-looking animal, its movements very much
resembling the walk of the looper caterpiller (Brim-
stone Moth), also a specimen of Nympkon gracilis,
very few shells, and those very common ones.
On looking over the result the next day, I found a
great quantity of foraminifera. I also found a few
sponges and zoophytes : of the latter, Laomedea
genicidata was the most common ; also two specimens
of Luccrnaria, and, of course, any quantity of
Membranipora pilosa.
The next day's work was undertaken in company
with Dr. Battersby, who kindly gave me the benefit
of his knowledge of this coast, of which he is a
resident, and we judged it wiser to commence lower
down the coast, off a small coast-guard station, called
Kells ; but although the water was considerably
deeper and more sheltered, we found very little more
to reward the trouble : a few shells, all dead and
containing Pagurus, a dead specimen of the "shoul-
der of mutton " shell {Aporrhais pes-pelicani), and
one living ATatica. In the cavities of some of the
roots of the Tangle {Lai/iinaria bulbosa) brought up,
-a few specimens of Patella pellucida were found. We
also obtained a few specimens of Ophiocoma ncglecta
and one of O. rosida ; but on the whole, probably
because of the sharp currents running along the
•coast, the conditions conducing to animal life were
not very favourable.
Before concluding, perhaps a few words respecting
the method of preserving specimens collected would
not be out of place. The best methylated spirits of
wine and ordinary sea-water mixed in the proportion
of one part spirit to five water, is as good as any for
the majority of forms. In first mixing, the spirit,
owing to the resin in it, is apt to throw down a cloudy
precipitate. This may be got rid of by adding to the
mixture about an ounce of bicarbonate of soda to each
quart, and filtering the whole through paper. Sea-
weeds may be simply spread out and dried. If it be
wished to get the shells of foraminifera from sand
dredged up, a good plan is to dry the sand
thoroughly in a moderately warm oven, and when
perfectly free from moisture, allow them to cool, and
gently place the whole in a vessel of water, when the
sand will sink to the bottom, whilst the foraminifera,
containing air in their chambers, will float. The now
separated foraminifera may be easily selected under
a lens by simply picking them out with a camel-hair
brush, to which they will adhere, if it be drawn
through the lips : they may be afterwards mounted
dry or in balsam. Before throwing any of the dredge
contents overboard, it is a wise plan to place the sea-
weed, or at least the feathery forms, in fresh water,
as unexpected discoveries are revealed by this means —
minute forms, whose very existence was unsuspected,
are compelled to declare themselves.
To briefly sum up, the dredger must have plenty of
patience, must not mind wetting, evil smells, although
on a sandy coast this is not very bad, and must trust
as little as he possibly can to a boatman's assistance
in soiling over his spoil, else half his treasures will
be lost. A few good books for identifying his results
are, I need not say, invaluable. The ones I have
found very useful are Gosse's "Marine Zoology:"
this will give the genera of the animal spoil, while
"British Sea-weeds," by W. H. Harvey, will supply
the botanical want. If, however, the latter is too
expensive, there is a small shilling book by Mrs. Lane
Clarke that is veiy useful. One, however, of the best
general books, embracing a good deal, in fact, of nearly
every class of sea plunder that the beginner is likely
to come across, is "Half-hours at the Sea-side," by
J. E. Taylor.
In conclusion, I can assure my readers that if any
one of them care to devote his holiday to dredging,
he will not only make a great acquisition to his
marine knowledge, but also to his health ; and I only
wish that he may have as lovely surroundings in
scenery as I had. H. A. Francis.
HOW TO MAKE AN HERBARIUM.
A CHAPTER FOR YOUNG COLLECTORS.
By John W. Buck, B. Sc
AS the summer advances doubtless many young
lovers of nature will begin again gathering
wild-flowers, and bringing them home in nosegays, as
they have often done before, to be looked at for an
hour or two and then, when withered, thrown away.
Some may have tried ere this to dry them, and so
to keep a record of their industry and their love for
flowers, but may not have succeeded to their own
satisfaction for want of a little help or instruction to
begin with. It is for such that I intend this paper.
To make an herbarium may sound a very imposing
task, but such it need not be, for it can be done
slowly and gradually — a plant at a time, if need be —
and the flowers, when thoroughly dried and mounted,
if taken care of will keep an indefinite time and be a
lasting source of enjoyment. Nothing is so condu-
cive to a knowledge of our British wild-flowers as to
make as complete a collection as possible of them ;
although those who take my advice and make the
attempt will probably be surprised to find how few
flowers they already know, and how many there are
hidden away under the hedges or in the woods which
they never saw before. An object such as this gives
a new zest to our country walks, besides making us
find out new ones ; gives us pleasant associations
with particular spots as being the places where we
first found such and such a new flower, fern, or moss ;
and above all gives us new and brightened views of
nature and of nature's God.
HARDWICKE'S SCIENCE-GOSSIP.

To collect flowers for an herbarium, all that is neces-
sary is a tin box and a trowel, though some collectors
prefer to carry a portfolio containing porous paper
and to put the plant under pressure on the spot. This
has the advantage of securing that the flower shall
lose none of its freshness while being carried home ;
but it is a cumbrous and troublesome plan, and it
will probably be found, in the case of most flowers,
that if they are brought home in a biscuit-tin, and
the roots perhaps placed in water to freshen them up
if necessary before pressing, that they will appear as
good as need be. It will nevertheless be found very
convenient to carry a small pocket-book with some
porous-paper leaves, in which to preserve at once
some blossoms which will require it. For instance,
it will be found impossible to bring home an entire
Dandelion or Bindweed without the blossom closing
up ; and the corolla of the Germander Speedwell, the
bright little blue flower often called Bird's-eye or Cat's-
eye, that looks so pretty and lasts so long in the
summer hedgerows, will almost certainly be knocked
off before the plant can be pressed at home. In such
cases these parts must be put under pressure separately
from the rest of the plant, and at once. Indeed,
such a sleepy plant as the Tragopogon, or John-go-to-
bed-at-noon, almost requires to be caught with guile.
Go in the morning when it is open and press the
blossom in the porous-paper book before detaching it
from the stalk. Some entire plants, from their delicate
and brittle nature, had better be pressed on the spot ;
as, for instance, the pale-green Moschatel, the stalks of
which are almost sure to snap with the slightest rough
usage. Of course, when the roots have to be cleared
from much earth, especially if the earth is of a clayey
nature, it is absolutely necessary to bring the plant
home before doing anything with it. On the whole,
the tin box will be found preferable to the portfolio,
and the occasions on which the latter must be used
will soon be learnt by experience. Better than either,
because more convenient, is the regulation vasculum,
of japanned tin.
For digging up the plants, since in most cases the
roots must be preserved, a trowel is generally recom-
mended. After a few of these have been broken by
rough usage in stiff soils, or spoilt by friends who
have borrowed them "just for once," they will pro-
bably be replaced by a small three-pronged fork, about
the same size as the trowel, but much more durable.
Even this, however, has its disadvantage, which will
be found out on trial. In selecting the specimens for
preservation, a little discrimination should be exer-
cised. It is best, perhaps, to take two plants of the
same kind and dry both, and afterwards choose the
best of the two for mounting. It is not advisable to
take more, unless they are somewhat inaccessible, or
unless, for other reasons, it should be difficult after-
wards to obtain more if required, as a large number
only fills up the box, takes up a great deal of room in
the press, and gives much unnecessary trouble in
many ways. Choose, therefore, two plants which are
fairly developed, and which show, if possible, speci-
mens of all the kinds of leaves the plant may possess,
which have some blossoms fully open and others in
bud, and, in short, which are in all respects good
specimens of their kind. In some cases the leaves
are not up when the flower is open, as with the
Yellow Coltsfoot, which flowers in the early spring,
but whose leaves are not to be found until much later.
It is a mistake to choose too large a plant, under the
impression that it will look well ; a medium should
be aimed at in this matter, as in everything else.
Perhaps it is not unnecessary to say that rare plants
ought not to be exterminated. Persons who go about
hunting for rarities, and who take all they can lay
their hands on, are collectors only, not botanists.
Many of our uncommon ferns are daily becoming
rarer, and harder to be found by those who really
want to study them, because they are so diligently
sought after and dug up by collectors who only want
them to sell. My advice is, if you find a rarity, take
of it in moderation, and then, in the interests of
science, keep your own counsel as to its where-
abouts.
In removing a plant, care must be taken not to
spoil the root, nor to injure the deaves that spring
from near the ground. It is often of great importance
that these latter should be kept intact, as they fre-
quently differ from the leaves which grow higher up
the stem, and are very useful in assisting to determine
the name of the species. With many plants, as is the
case with the Coltsfoot, the root will be almost sure
to break off sooner or later. Again, a complete Blue-
bell, bulb and all entire, will be a very good certificate
of perseverance for its possessor. The adhering earth
should be shaken off as far as possible without doing,
injury to the roots, and the rest carefully pulled off at
home, or removed by holding the root (only) under
a stream of water.
The next thing ought to be to name the specimen ;
and if I could take for granted a little knowledge of
botany on the part of my readers, it would not be
very difficult to show in brief the easiest method of
arriving at the correct botanical and popular names
of most of our common wild-flowers. For those, how-
ever, who know nothing of botany, the best way is to
compare the flowers brought home with the illustra-
tions in some such work as Ann Pratt's " Wild-
Flowers," or John's "Flowers of the Field," or
Sowerby's "English Botany," or to obtain the help
of some botanical friend. At all events, you need
not despair of making good progress with your her-
barium, even if you do not know the names of all the
plants it contains, as these can generally be added
afterwards.
In any case, proceed to dry your plants before
they lose their freshness. This is accomplished by
pressing them between porous paper. The best
paper for the purpose is, or used to be, made by
136
HARD WICKE'S SCIENCE- GOSSIP.
Messrs. Spicer, of New Bridge-street, Blackfriars
(who also supply white paper for mounting, in sheets
nbout 17 in. by 11 in.), but in default of this, thick
blotting-paper is said to answer, though I have not
tried it. The plants must not be damp when they
are put in the press, and if the roots have been
washed to clean them, they should be wiped as dry
as possible. If for any reason the plants are at all
damp, the papers should be changed very frequently
at first, even twice a day, until the excess of moisture
has been removed. I am frequently asked, "How
is it you manage to keep the colours of your flowers
so well ? " Mainly by attention to this point — by
not allowing the flowers to remain damp. Otherwise
they are very apt to change their colour ; as, for
example, the Wood Anemone, or Windflower, which
.generally turns brown, but which may be kept white
with proper care. Heaths and firs are said to require
a dip in boiling water before drying, in order to pre-
vent the foliage from falling off. The same process
prevents succulents, such as the curious flesh-coloured
parasitic Toothwort, from growing during or after
pressure, by killing them at once. Here, also, the
superfluous moisture should be removed by a hand-
kerchief before pressing. Do not mix fresh speci-
mens with dry ones, but separate them with several
sheets of brown paper. Laying -the plants out will
often be found a troublesome process, and one which,
in order to do it well, will in some cases require time
and patience, but it is not of much use to give advice
on this head, except to say that the various parts of
the flower should be as well exhibited as possible.
For instance, where the flower has a coloured calyx
and no corolla, as in Marsh Marigold, Clematis, and
Wood Anemone, one blossom should be folded up so
-as to show the absence of the customary row of green
leaves below the coloured ones. Or the same subject
may be effected by completely reversing one blossom,
so that its face is towards the paper. Where bracts,
or small leaflets at the base of the flower-stalks occur,
as in orchids, they should be shown. The specimens
should be distributed among the sheets of porous
paper in such a way that the pressure may be some-
what equal in all places ; but those plants, however,
are likely to dry more quickly which are nearer the
margin of the sheets. Thick stems had better be
sliced in half longitudinally, as it prevents their
taking up too much room, and also enables them to
dry veiy much faster. The same course may be taken
with thick roots or root-stocks, as in Primrose and
Coltsfoot ; but in such cases care must be taken to
leave enough root-fibres adhering to the main axis.
Bulbs and corms, and the fleshy tuberous roots of
orchids may also be sliced ; some recommend scooping
out the inside, but this is apt to make them break and
spoil under pressure. Berries and stems that are not
thick enough to slice may be repeatedly pricked on
their under surface, or slashed with the point of a
penknife, to let out the moisture. A very good plan
with fleshy berries, and thick stems and roots, is to
dry them, apart from the rest of the plant, by pressing
them between several folds of porous paper, and
baking the whole for three-quarters of an hour in an
oven. But this does not always answer, and should
not be tried with green leaves, as it is apt to turn
them brown. In short, the more rapid the drying
process the better ; and hence the necessity of having
recourse to these contrivances in order that the colours
of the blossoms may not be injured through being
kept damp by the slow drying of the thicker parts.

MICROSCOPY,
" Cutting it fine." — At the usual conversazione
which followed the ordinary meeting of the Quekett
Microscopical Club on April 26th, Mr. E. T. Newton
exhibited thirty-three sections of the head of one cock-
roach ! — Blatla Orientalis.
Fossil Diatomace^e. — The Diatomaceze in the
Cementstein are described and figured (very beauti-
fully) by Dr. Heiberg, in his " Kritisoversigt over
de Danske Diatomeer." The richest in diatoms is
the Cementstein from the island of Mors, situated in
the Liimfjord, lat. 560 50' N., long. 8° 40' W. This
fjord is the largest in Jutland, and runs from east to
west, connecting the North Sea with the Kattegat.
The material is also known as "Jutland slate." A
similar deposit occurs in Fuur ; it is less affected by
acid, and bears considerable resemblance to the de-
posit known as "Brown coal." Another deposit is
found at Nykjobing, a village on the western side of
the island of Mors. This is much more difficult to
prepare, neither acid nor alkali making much im-
pression upon it. The following forms have been
described and figured by Dr. Heiberg in his treatise,
and by myself in the "Journal of the Quekett Micro-
scopical Club," in the Parts for 1870 and 1871.
The following are the most abundant forms in the
Mors deposit : — Trinacria regina, Heiberg; T. cx-
cavata=.Triccratium solenoceros, Ehr= T. A'ittou-
ianum, Greville ; Trinacria Hcibcrgia, Kitton ; Do.
var., Kitton; Triceratium maculatum, Kitton;
Solium exsculptum, Heiberg ; Corinna elegans,
Heiberg ; Stictodiscus angulatus, Grunow ; Stcpha-
nogonia Danka, Grunow; Trochoscira mirabilis,
Kitton ; T. spinosa, Kitton ; Hemiaulus protcus,

Heiberg; Do. (q. sp. ), Kitton; Coscinodiscus sicl-
latus, Roper ; C. radiatus, Ehr ; C. octdus Iridis,
Ehr ; Stephanopyxis (qu. sp.) ; Aidacodiscus yut-
landkus, Kitton. Triceratia occur in the Barba-
does, Californian, and Morsa deposits, as well as in
the Virginian "earths." — F. Kitton, Norwich.
Aquaria for MicROSConc Work. — In answer to
W. D. B., I would suggest that I find several small
aquaria (none of them holding more than a quart)

much better for microscopic work than a large one,
for we can hold one vip to the light with one hand
and use the dipping-tube with the other. We are
able to keep a better and more varied assortment,
and the depth is better for dipping. Anatomical
specimen-jars and beakers I find to be most con-
venient, but wide-mouthed bottles maybe substituted
on account of cheapness. I have usually about thirty
in use, some of them being very small, and I never
find it necessary to change the water. Covers of
muslin, cardboard, paper, or glass can be used.
Among the plants I find to be useful are Elodca
canadensia, species of Chara, Callitriehe verna, Sca-
pania undulata, Pilularia globidifera, Moniiafontana,
and species of bog and water Hypna. — Wm. West,
Bradford.
Small Aquarium for Microscopic Objects. —
It is likely that W. D. B. may have some difficulty
in finding his animalculce, &c, if he should put them
into a tank of thirty inches length and proportionate
depth and breadth. I recommend him to make
much smaller ones upon the following plan : — buy at
the grocers some of the empty tin boxes which have
held between two and three pounds of Huntley &
Palmer's Water Biscuits (mind, Water), cut out the
ends and sides, leaving a framework sufficient to sup-
port the glass, and you have at once the skeleton of a
handy and well-proportioned tank. Cement the
glass with a mixture of red and white lead, let it set
for two or three days, then fill the tank with water
and let it remain for a week, so that the taint of the
lead may be removed ; empty out, put a layer of well-
washed Calais sand at the bottom, and the tank is ready.
Mount it upon a slab of wood, and put four slips of
thin wood to retain it in position. The tin frame
should have two coats of paint or Brunswick black.
I prefer the latter.—^. P. W.
Canada Balsam in India. — Will slides mounted
in balsam stand the heat of India ? Would it be suffi-
cient to surround the cover with some heat-resisting
cement ? If balsam will not do, what other medium
Mill ?—//. F. Blaekttt.
The Hackney Microscopical Society. — This
society, which specially devotes itself to the study of
microscopy and natural history, has just issued its first
annual report. We are glad to see abundant signs of
vigorous health, although the society is only a year
old. The president is Mr. H. Ramsden, M.A.,
F.L.S. ; and the hon. secretary, Mr. Collis Willmott.
The list of members is numerous, and includes many
names well known in science. Papers on various
natural history subjects, chiefly entomological, have
been read, and five field excursions made during the
summer. The foundation of a good natural history
library has also been laid, and with such a start we
shall look forward with interest to the progress of
ihe society during its second year.
ZOOLOGY.
The Uraniid.-e. — At a recent meeting of the Zoo-
logical Society, Professor Westwood communicated
a memoir on the Uraniida:, a family of Lepidopterous
insects, with a synopsis of the family, and a mono-
graph of one of the genera, Coronidia. These insects
were remarkable for their extreme beauty, and the
difficulty which had attended their systematic classifi-
cation. Their relations with other groups of Lepido-
pterous insects were discussed at considerable length,
and their numerous affinities were shown to be with
certain other moths belonging to the great division of
the Bombyces, whilst their connection with the Hes-
perian butterflies, the Pseudo-sphinges, Erebideous
Noctre and Ourapterygeous Geometra2 was disproved
by their general structure, the venation of their wings,
and their transformations. A synopsis of the species
of all the genera was given, and a complete mono-
graph with figures of the genus Coronidia.
The Brachiopoda of the Atlantic. — At the
same meeting Mr. Gwyn Jeffreys, F.R.S., F.Z.S.,
read a paper on the above subject. The areas from
which the Brachiopoda were obtained were restricted
to portions of the North Atlantic, including the
Mediterranean. A table of all the Brachiopods known
to inhabit the European seas was given, comprising
ten genera and twenty-two species, of which latter
four were for the first time described, and six figured.
The table also particularized the geological and ba-
thymetrical range of all the species. Two plates
accompanied the paper, and were furnished by
Mr. Davidson.
Mimicry in Birds. — Mr. J. Young writes to
Nature to say that in a tract of land on the coast of
Kent called Reculver Marsh, the place is much fre-
quented by skylarks and plovers, and that almost all
the larks have incorporated the well-known alarm-
note of the plover into their song. Professor Newton
remarks that this fact has already attracted notice ;
for at Thetford, in Norfolk, where the ringed plover
is common, skylarks often mimic its peculiar cry.
Starlings are said to have acquired the cries of various
kinds of birds, notably those of the plover and
swallow. Jays are also stated to imitate the note of
the carrion-crow.
The Nightingale in Derbyshire. — Pray let
me note to you, and through Science-Gossip to
others, the pleasing fact that a nightingale has made
its appearance here, and has been nightly for the
past week (and is still) singing its sweet song close to
this village. It is but seldom that the nightingale
visits Derbyshire at all, and this is the first time, so
far as my knowledge goes, of its ever having come so
far north in our county as Winster, which, as you are
aware, is in the Peak district. It will be well, with
your permission, to make known this visit through
Science-Gossip. — Llewellynn Jewitt, F.S.A., &c.
HARD WICKE'S SCIENCE - G OSSIP.
Development of Proteus Anguinus. — Pro-
fessor Schulze has recently discovered the mode of
development of this blind amphibian. He found a
specimen in the Adelsberg cave which had laid
fifty-six eggs. The Proteus is proved, by researches
on the ovary of a female from which the eggs were
taken, to be oviparous.
The Cumberland Association for the Ad-
vancement of Literature and Science. — A
capital plan is in successful action in Cumberland,
whereby scientific societies in six of the chief towns
are affiliated into the above association. The annual
gathering was held in Cockermouth in Easter week ;
when Mr. Isaac Fletcher, M.P., gave the presidential
address. Afterwards, Sir George Airy, the Astro-
nomer-Royal, delivered what he said would most
probably be his last lecture, on " The Interior of the
Earth." Mr. J. Clifton Ward, F.G.S., the hon.
secretary, read a valuable paper on ' ' Quartz in the
Lake District." Various other papers were read.
The Northampton Natural History So-
ciety have issued their second report, which shows a
numerical increase in members, and a uniform success
in all their efforts. The meetings have been held
monthly, at all of which papers have been read. A
list of the Lepidoptera of the county is being pre-
pared by the President of the Entomological Section,
Mr. A. Perry. The President of the Socie ty is the
Right Hon. Lord Lilford, and the Hon. Sec. Mr.
G. C. Druce.
Early Appearance of Colias Edusa. — Mr.
W. H. Liversedge saw three specimens of Colias
edusa, on Monday, April 22, while driving near
Ryde, Isle of Wight. They were strong on the
wing, as if freshly emerged, or they may have hyber-
nated in the imago.
New British Crustacea. — Mr. Spence Bate has
described two new species of small Crustacea, found
by Mr. .Sims of Aberdeen. One species belongs to
the DiastyluJa, and the other to the Amphipoda.
The former has been named Diastylis bimarginalus,
and the latter Lestrigomis spinidorsalis.
Salmon Disease. — Mr. Worthington Smith de-
scribes and figures the disease which this spring has
destroyed such numbers of salmon in the Eden and
other rivers. It is the result of the growth of a
fungus, Saprolegnia ferox, in enormous quantities ;
and Mr. Smith thinks the unusually vigorous growth
may be due to the mildness of the past winter.
BOTANY,
Summer Lady's Tresses (Spiranthes astivalis). —
I am quite sure all botanists will deeply regret to
learn that this rare plant— which, like Gladiolus
illyricits and Pulmonaria angustifclia, is to be seen
nowhere in England but in the New Forest — is being
rapidly cleared out of its station near the Lynd-
hurst and Christ church Road. I have reason to
fear that in two years not a single specimen will
be found in the famous Spiranthes bog. This is
deplorable — and I must explain how this much-
to-be-deprecated eradication is being effected. The
year before last a second edition of the "New
Forest Handbook " was brought out, comprising,
among other additions, a short paper on the botany
of the district, and in this the author thought fit to
describe, with almost painful minuteness, the exact
locality of the bog. This, no doubt, was kindly
meant, but the consequences are lamentable, as I
shall presently show. In the vicinity of Lyndhurst,
and in many other parts of the Forest, there are resi-
dent "collectors," who collect insects (chiefly Lepi-
doptera), birds' eggs, rare ferns, and anything else
which is marketable, and dispose of them either to
London dealers or to visitors. Now, when the hand-
book appeared containing the notice of Spiranthes
cvstivalis, and referring to it as "a plant quite peculiar
to the New Forest, and to be found in no other spot
in England," they saw at once a rare opportunity for
increasing their returns ; since, by carefully pulling up
every plant they could find, they would hold the
monopoly, -and always be sure of a ready and certain
sale. This was made more apparent when large
numbers of visitors flocked to the bog last year, even
as early as May, and when orders for specimens came
in from all parts of the kingdom. Their anxiety to
discover the plant as early as possible was very great,
and on more than one occasion I have been asked
what it looked like, and how they might know it, for
a plant a few inches high, with a lax spike of small
white flowers, growing in a very wet sphagnum
bog, is not very likely to attract much attention.
In the month of August I called at one of the
cottages close by and inquired about the Spiranthes.
I was told that the day previously it had been found
by a visitor. " So," continued my informant, "as we
have so many people asking about them, and so many
orders, we went out last night and this morning and
brought in every plant that was in blossom. I'll show
you them," and— shall I say it? — to my intense dis-
gust a large earthenware pan, about two feet in
diameter, was brought out completely filled with,
Spiranthes astivalis — roots, flowers, and all ! Besides
this there was on the table a good handful of cut
blossoms. I said I would walk over the bog and see
if there were any more, which called forth the remark :
"I don't think it's of any use, Sir; I don't think
there's one left." However, I searched, and after
wading half-knee-deep in water for an hour or so,
succeeded in finding three specimens, two of which I
took, and afterwards reproached myself for leaving
the third ; for I felt sure it would be gone next day.
I have not visited the cottage since, but I have no
doubt that every visible specimen was ruthlessly

pulled up. The only chance was for young plants
which did not blossom — these of course are bound to
go this year ; next year the last lingering vestiges will
be swept away, and Spiranthes astivalis shall never
again flourish at its celebrated station in the New
Forest of Hampshire. Nothing can save it. Other
bogs will, when this one is exhausted, be searched,
and if, as is said, the Spiranthes occurs elsewhere in
the neighbourhood, it will soon be a thing of the past,
and one of the very rarest plants in the United King-
dom will be extinct, unless specimens are procured
from the Channel Islands and planted. Can anything
be done to prevent its complete extirpation? I do
not for a moment blame the cottagers ; if a wild plant
will fetch a given number of shillings in the market,
these people have, undoubtedly, as great a right to
sell them as have more wealthy collectors to travel a
long distance in order to gather them for themselves.
The plants do not belong to anybody in particular,
and the cottagers may as well make money out of
them as by the sale of a Vanessa antiopa, a Montagu's
Harrier, or a nest of raven's or honey-buzzard's eggs.
The error lies in making the habitat of a rare plant
publicly known. When will kind-hearltd uotanists
learn that it is a grand mistake to publish the exact
habitat of a rare or local species ? It is disheartening
enough to know that a plant is gradually becoming
more and more scarce in a district, yet it is some con-
solation to know that it grows in other parts; but
what must be the feeling of all right-minded botanists
on learning that the only spot in the kingdom in
which a species flourishes is being rapidly and surely
shorn of its glory? Spiranthes cestivalis, compared
with other orchids, has but small pretensions to
beauty, and is far from being a conspicuous plant;
and growing in the very wettest part of a peat bog,
might have escaped destruction, and continued to
flourish for many long years to come. The (per-
haps) well-intentioned, but most injudicious, publi-
cation of half-a-dozen lines will, in all probability, be
the means of extirpating it, and robbing the British
flora of one of its brightest gems. — E. D. Marquand,
Brockenhurst.
Orobanche on Begonia. — We have in our
greenhouse an Orobanche that has arisen from the
roots of a Begonia. In the field close to the house
every year we have many Orobanche minor, arising,
we presume, from the roots of clover. We therefore
thought that it might be this plant, but from the descrip-
tion, which I send you, you will see it is not. Sepal
with no vein, or if with one vein, very indistinct ;
ovate below, narrowed into one subulate point shorter
than the tube of the corolla ; corolla tubular arcuate ;
lips denticulate, wavy ; lobes of the lower lip nearly
equal, middle one largest ; upper lip emarginate,
sides patent. Stamens inserted near to the base of
the corolla tube, slightly pilose, anthers dark brown.
Stigma approximately two-lobed, pale red. Bract
one. Leaves none. Stem purplish, four inches high.
— T. y. Edwards.
Look at the Hedgerows during June. —
Mr. Hobkirk some few years since, in the pages of
the "Naturalist," gave us an admirable article- on the
sub-species of the Hawthorn ; until then they ap-
peared to be overlooked by British botanists, or they
merely regarded them as a single species. For several
years they have furnished to us matter for thought
and study, so that now we can generally when riding
rapidly along the lanes point out any of the species,
or varieties, when in flower. What we particularly
wish, in fact our object in drawing the attention of
our readers to them, is to ascertain their distribution.
For the present, and as the space at our command
must be limited, we describe only two of the species,
probably both will be discovered in many counties : —
i. CraLegus oxyacanthoides, Thnil, may be recognised
with ease, by having from two to three carpels, and
the peduncles and calyx tube being glabrous or
smooth. — 2. Cratcegus monogyna, J acq. Carpel
solitary, peduncles and calyx pubescent (clothed
with fine down). The leaves are large, and deeply
lobed. No. 2 is our common species in the North
of England, No. I more rare. — F.
Fertilization of Mergenia Erecta. — At a
recent meeting of the Linna;an Society, Mr. R. I.
Lynch read a paper on the mechanism for the fer-
tilization of the above plant. It is a West African
Acanthaceous shrub, bearing funnel-shaped corollas,
with hairy anthers midway in the tube, their backs
pressed against the wall. The lower slender flexible
style has its double-lipped stigma so formed and
placed, that insects alighting and entering towards the
nectar at the bottom of the flower, on their return so
move the lever-lip of the stigma as to produce pol-
lenization.
Position of the Pasque Flower. — I have
noticed that whenever I have found the Anemone
Pulsatilla it has always grown in belts of a certain
altitude, as for instance : last year on the Blewberry
Downs I found the above specimen ; it was growing
in a belt at about 40 feet elevation, and the belt only
being about 25 or 30 feet broad. I was rather sur-
prised at this, and determined to take notice this year ;
I have done so, and again noticed the same pecu-
liarity. I have never found one out of the belt. I
have consulted many Botanies, but have seen no
record of so marked a peculiarity in this specimen.
The question is whether this is a universal fact or
only a partial one, occurring only in the localities in
which I have found the Pasque Flower. — Albert
Henry Barrett.
Experiment with Mistletoe Berries. —
Having just been making an experiment with the
above, I thought it probable that some of the
14°
HARD WICKE 'S S CIE NCE - G O SSIP.
readers of Science-Gossip might be interested there-
with. About a fortnight after Christmas I took some
mistletoe berries, which had already done duty as
decorations during the festive season, and squeezing
each one separately, applied it to a branch or twig
of a little hawthorn hedge. This hedge is now about
three years old and is in vigorous growth. I applied,
altogether, about two dozen seeds, without opening
any of the bark at all, and left them to maintain their
position by means of the viscous matter surrounding
them. For a long time I could observe no outward
difference on them, with the exception that they
seemed to be swelling, so I had hope that life was
present. About this period I one day observed that
two or three of them had been pecked out by the
birds. However, as I did not notice any more
marauding behaviour of this kind, I am hopeful that
a considerable percentage of the seed thus sown may
grow. The next step in the way of progress — the
seeds in addition to having become considerably
swollen became of a bright green colour, and on
several of the finest I could distinctly make out the
lobed character which the cotyledons still wrapped
together are beginning to assume. Last week, as I
was making one of my daily inspections, I became
aware of several of the little seeds having effected
a junction with the branches they are attached to.
Since then I have observed more of them, and I am
congratulating myself that my venture will succeed.
As the hedge is now fast becoming green it daily
becomes a more difficult matter to find out the where-
abouts of my friends. I must now wait to the end of
the year, when the Hawthorn puts on its winter garb,
before I shall be able to count how many have
"taken." As Devonshire is famous for producing
very little of the mystic parasite, I have had the more
pleasure in my pursuit, and hope that the " Mistletoe
Bough " may become a permanent denizen of my
hedge. — J. Mills Higgitis, Silverton, Devon.
GEOLOGY.
Gold in New Guinea. — The discovery of gold i
in this hitherto unknown country promises, ere long,
to make us better acquainted with its natural history
and mineral productions. Expeditions are being
fitted out, both in Australia and New Zealand, for
the exploration of the interior, and the collection of
general trustworthy information.
Ancient Vegetation. — Professor Claypole has
found the remains of Lepidodendron-like plants in
the Clinton limestones of Ohio, belonging to the
Upper Silurian period. The provisional name of
Glyptodcndron has been given to this, the oldest
known American plant. As representing arborescent
vegetation, it may be regarded as the oldest known
specimen in the world.
Fossil Insects. — Mr. Scudder is preparing a
work on the fossil insects of America. He has
recently spent a couple of months in the Western
Territories, collecting fossil insects. Six to seven
thousand specimens were obtained from Florissant ;
all being remarkable for their beautiful preservation.
There is every reason to believe that the tertiary
strata of the Rocky Mountains are richer in the
remains of fossil insects than any other part of the
world. Mr. Scudder possesses more than twelve
thousand specimens.
Fossil Fresh-Water Sponges. — Mr. J. T.
Young, F.G. S., announces the discovery of spicules
of fresh- water sponges in the so-called " flints " found
in the Purbeck limestones. The spicules are like
those of Spotigilla Jluviatilis, only larger. This is
the first discovery of fossil fresh-water sponges in
Great Britain. Mr. Young has called his specimen
Spongilla Pio beckensis.
NOTES AND QUERIES,

How to Make Plaster Casts of Fish, &c. —
I have read with much interest your article in SciENCE-
Gossip on the making of " Plaster Casts of Fishes."
Being a user of plaster in my occupation as a dentist,
I venture to give you a better plan of managing that
material. The process of mixing water with plaster
should be as follows : — Put water first into the mixing
vessel, and then add the plaster to it by shaking it
from a scoop as evenly as you can into all parts of the
water (in large quantities through a sieve), until the
dry plaster floats on the surface ; stir it slowly a little ;
then you have the proper quantity to make it of the
consistence of cream, which is also the proper consist-
ence to use for casting ; then shake or jar the vessel
a little, and let it stand for a few seconds to get rid of
air-bubbles. The plaster, in this state, will give
plenty of time to mix more and add if necessary.
You may use any quality ; but I should prefer "super-
fine," 9s. per cwt. Trusting this will facilitate your
interesting work. — E. R. Pearce.
A Plague of Flies. — A small district, lying in
the counties of Antrim and Derry, has this spring
been afflicted with a plague of flies, entailing both
inconvenience and loss to the inhabitants. The area
affected was the river Bann, for about a mile and a
half of its course, near Kilrea, and the pastures
adjoining. The stones and plants in the river were
completely encrusted with the pupa-cases of the
insects, from which they issued in millions and
attacked both men and cattle. The latter had to be
removed from the vicinity, and many of the people
had their heads and necks much swollen, owing to-
the venomous nature of the sting with which the
insect was armed. The flies lived only for a few
days, and left their dead carcases heaped up on the
river banks, in some places three inches deep ; they
have now (1st May) almost disappeared. Some of
those supposed to be wise in such matters think that
these flies have had their origin in the battle-fields of
Turkey ; others that their advent is a portent of omin-

ous coming disasters. I enclose specimens of the flies,
and also of the pupa-cases : I presume they belong
to the Tabanidas, or horse-flies ; but why have they
appeared in such force, and taken possession of the
limited area referred to, where they had not attracted
attention previously? — S. A. Stewart, North-street,
Belfast.
Removing Surplus Balsam. — Allow me to call
the attention of those microscopists who mount their
own objects, to a most useful and effective implement
for removing surplus balsam. It is the invention of
Mr. Carey, of Norwood, and can be seen, by his
permission, at Mr. Baker's, 244, High Holborn. I
call it "The Carey Scraper." In using it, heat accord-
ing to the hardness of the balsam, and run the scraper
round the edge of the covering-glass, wiping off the
removed balsam on a piece of paper. It comes off
freely, and leaves but very little on the slide to be fin-
ished off by benzole or other spirit.- — John Bramhall.
Natterjack Toad on the Shores of the
Solway Firth (p. 67).— Sir William Jardine
mentions the Natterjack as occurring "in a marsh
on the coast of the Solway Firth, almost brackish,
and within a hundred yards of spring-tide high-water
mark. It lies between the village of Carse and
S otherness Point, where I have found them for six
or seven miles along the coast. They are very
abundant." The late Mr. Edward Newman also, in
an article on the Natterjack published in the " Zoolo-
gist " for June, 1869, writes :• — "In Scotland it has
been found abundant on the coasts of the Solway
Firth."— W. R. Tate, Blandford.
The Natterjack Toad in Cumberland.— I
have for several years known of the existence of this
toad on the shores of the Solway, at Silloth, a few
miles from the locality noticed by your correspondent,
Mr. Duckworth. I have from time to time obtained
specimens by digging them out of the sand, where
they hide during the day. They are found in
burrows, sometimes a foot or more deep, opening
usually at the top of a "scree" of sand, just beneath
the overhanging turf. I have found from one to
three toads in each hole. Last June I found that
they frequented a pond near the railway station by
hundreds. Their croaking, which was intermittent,
beginning suddenly and ceasing as abruptly after two
or three minutes, could be heard on a still evening
more than 500 yards away. This toad, like the
common one, has the chameleon-like property of
being able to adapt its colour to surrounding circum-
stances. Those found in the sand were of a beautiful
light grey, almost without any spots. Those found
amid the moss and slime of the pond had large
blotches of greenish yellow, not at all improving to
their appearance. — T. Lattimer.
Wood-Pigeons' Nests. — I was much interested
a few days ago, in seeing a pair of wood-pigeons that
are building a nest in a tree, in a garden a few feet
from the backs of houses and a public road, and not
many hundred yards from a large railway station and
a busy thoroughfare, with tram-cars and omnibuses to
the City and West End. Is it not curious that birds,
so associated in our minds with peaceful country
scenes, should choose a spot so very near the great
desert of bricks and mortar? If the poor birds are

The Whitethroat a Mimic— A curious inci-
dent occurred to my observation on Saturday
afternoon, 4th May. While walking across a mea-
dow I heard, proceeding from the hedge on the far
side, a variety of guttural sounds, in which I recog-
nised the song of the whitethroat ( Curruca eiiierea), but
it was strangely interrupted by the alarm notes of the
common swallow, sparrow, green and grey linnets,
greater and lesser tits, and possibly a few others
which I did not recognise. At first I was convinced
that the several species were present. I drove the
whitethroat out of the hedge, upon which he pro-
ceeded to a neighbouring one, and there resumed his
imitations. Being anxious to make sure of this, I
lay down near the hedge where I formerly heard him.
In a short time he returned to it, and I had a favour-
able opportunity of seeing him. I watched him
long enough to convince myself that every note
proceeded from the same species. This peculiar
characteristic of this bird I do not find mentioned in
any books on ornithology which I have read. — John

leech vases about eight inches in diameter, which I
get from the chemist for three and sixpence each. I

better than a larger aquarium. Among several other
advantages specimens can be kept separate, and the
bottom of the vase reached with the dipping tube. —

Colias Edusa and its Varieties. — The great
abundance of this graceful butterfly during the past
season has offered to entomologists more opportunities
of studying its nature and habits than they have had
for several years. The question naturally arises : — to
what cause are we to impute the strange appearance
in such numbers of this once-prized insect ? Many
are the theories that have been brought forward to
account for it, but the solution of this entomological
problem seems as far off as ever. Although the
investigation of it has been carried on for many years,
we have no explanation of this phenomenon that we
can receive with any particular amount of credit.
The suggestion that the insect we find here has
crossed the Channel, tempted by the fineness and
heat of an English summer, certainly cannot be put
forward as an argument in the case of last year. But
to dilate upon, or even to mention, the numerous
theories that have been brought forward to account
for this would occupy more time and space than I
have at my disposal. Another fact may be men-
tioned, namely, that the number of males taken was
very nearly double that of the females. The differ-
ence in the appearance of these is much greater than
one at first sight would suppose. The most striking
142

distinction is that the male has each of its wings
edged with a black border, unbroken except by very
fine yellow lines that are a continuation of the veins.
In the female this border is broken by greenish-
yellow patches, varying in size in different speci-
mens. Besides this there is another less striking
difference, namely, that at the root of each hind wing
in the male there is a light yellow spot, of which
there is no trace in the female. In the Science-
Gossip for last December one of your correspondents
remarks that he noticed in a specimen of this butter-
fly that the hind wings were suffused with a rosy
purple lustre. If he will carefully examine his speci-
mens, he will find this apparent peculiarity is common
in a greater or less degree to every specimen of the
male insect. Those male butterflies that had very
lately emerged from the chrysalis would display it
most vividly, while in the female there is not the
least trace of it. — C. E. B. Hewitt, Birmingham.

The Mighty Deep. — In your issue for April, I
find a very interesting paper on this subject from
Mr. A. Ramsay. Will you permit me to offer to
him, and to your readers, a brief remark upon it ?
Mr. Ramsay says — "The great bulk of the sea is
cencentrated in the Southern hemisphere " — and on
the authority of several authors he gives the most
probable mean depth at about 2,600 fathoms. In
the reports from the Challenger, as published by the
Admiralty, Nos. 1, 2, 3, 6, and 7, the mean depth of 446
soundings is about 1,716 fathoms 4 feet 1 inch. I have,
put down in the Geographical Magazine for March,
page 66, the mean depth of the Northern hemisphere
at about 1,907, and of the Southern at 1,642
fathoms ; giving a mean depth all round the world
of 1,774 fathoms 3 feet. The two means do not
coincide, because I omitted certain coast soundings
in the latter calculations. It follows, that the
volume, as given by Mr. Ramsay, must be wrong;
and though the surface-water area is more extensive
in the South, the bulk of water is about the same in
both hemispheres. The deepest water in the North
is 4,575, in the South 2,900 fathoms ; in the Arctic
regions 1,860, in the Antarctic i,Soo. There is water
round the North Pole, and land round the South.
The equilibrium of the globe seems perfect. The
mean depth of the ocean, beyond coast soundings,
may be put down at 1,750 fathoms; very nearly two
miles. If Mr. A. Ramsay can turn his attention to
the Geological Survey report of the Winter Moun-
tains, as published at Washington, U.S., he will find
some curious facts as to the depth of water in those
regions in times long past. — H. P. Maid.
The Natterjack Toad. — Can you tell me if it
is true that the Natterjack toad (Bnfo calamita) gives
forth a most intolerable odour when handled or
frightened ? I should be much obliged, too, if you
could inform me of any place near London where this
reptile may be met with. — y. Perrycap.
Our British Snakes. — In answer to a ques-
tion put in the February number of the SciENCE-
Gossip as to whether our British snakes eat birds or
mice, I can state positively that the viper eats both.
In 1876 I killed a viper, which I fcund to contain
six young willow wrens, feathered, and within a few
days of flying. Past year I killed a young one, which
contained a large long-tailed field mouse. Can any
of your readers give me any information as to how
or why the blind -worm carries its young in a case,
in its back, and how long this continues ? and do either
the viper or ringed snake do the same ?
Remarkable Nests. — This year we have noticed
three curious instances of a departure from the usual
habits of birds in building their nests, which seem
worth recording. The song-thrush lines her nest with
cow-dung and clay ; and it is usually considered by
ornithologists that, as she builds very early in the
spring and frequently in exposed situations, the mud
lining protects the eggs and the young brood from the
fierce March winds. Early in March we found a
thrush's nest in our garden, containing four eggs ; but
the nest had not a vestige of the usual mud lining.
Unfortunately we found the nest destroyed one morn-
ing before the bird had time to hatch, so it was
impossible to note whether the inclement weather
had any effect on the eggs. We have at this moment
a blackbird sitting upon six eggs, four of which are
her own and the other two those of the song-thrush.
When first the nest was found it contained two of
each kind, a thrush having laid in the blackbird's
nest. Although sparrows will sometimes appropriate
swallow's nests to build in, and though several birds
will build a new nest on an old foundation, it is, I
think, very unusual for one species — the cuckoo, of
course, excepted — to make use of a nest built by
another species. The third curiosity in nest-building
is the nest of a chaffinch, placed in the fork of an
elder-bush near our house. Usually the chaffinch
assimilates the colour of her nest to the situation in
which she places it ; if she builds in a hedge she
generally covers it with green moss ; but if she builds,
as she often does, on the bare branch of an old apple-
tree, she uses the grey lichens, which are usually near
at hand, and covers her nest with them so skilfully
that though quite open and exposed it becomes hidden
by its resemblance to a knob or excrescence of the
tree itself. In this case, however, though the bird
has recognised the necessity of covering her nest with
something, she has rendered it most conspicuous by
sticking little bits of white decayed wood all over it.
The wood is so white that the nest looks almost like
a snowball in the branches. Possibly this bird may
be colour-blind, or she maybe just a little bit " want-
ing" in her instinctive faculties, as human beings are
occasionally in their reasoning powers. Why not ? —
Robert Holland, Norton Hill, Runcorn.
How long can a Fish live out of Water ? —
A friend of mine some days since removed a gold-fish
from a glass globe, on account of its having mildew
(probably a parasitic growth of Epistylis). It was
placed in a basin of water at night on the kitchen
dresser. In the morning, at six o'clock, my friend
discovered the fish was missing from the basin, and
could be nowhere found. At past twelve o'clock at
noon the fish was discovered behind some plates
under the dresser ; as it moved when handled it was
placed in water, when it gradually revived, and is
now as lively as ever. This unfortunate fish was
certainly above six hours, possibly much more, out
of its proper element, and in my experience I have
never known one to survive one quarter that time. —
Henry Taylor, Peckham.
Sparrow-Hawks and Windows.— On hearing
a dash against a plate-glass window in an adjoining

placed it on its legs close by a plate of water ; it
gradually recovered, tried its legs, and in about ten

Early Appearance of the Swift. — I was
agreeably surprised this morning (May ist) by the
premature spectacle of a swift (Cypselus apus) hawk-
ing over this town. This is the more singular, from
the fact that the other summer migrants have been
unusually late in their arrival in this neighbourhood.
The swallows appeared first on April 19th. I heard

How to Destroy Ants.— Can any of your
readers inform me of the most successful mode of
destroying ants, so great a nuisance to many house-

"Dittany," &c. — Will some botanical expert
assist me to the exact name of the species of ' ' Dit-
tany" or " Dittander," and " Dictamiuni '? The
words frequently occur in the Elizabethan writers ;
but as their learned modern editors hold all natural
history in contempt, they merely copy from the old
dictionaries one after the other. The synonyms are
all confused ; as Floris says dittany is garden rue,
while Cotgrave gives garden ginger, peppermint,
■&c. ; then Halliwell says, the first is cayenne
pepper, and another authority that there is no such
thing; and Bentham (Handbook) adds that Dittany
is " the Fraxinella of Gardens," and not a British spe-
cies, while Dictamiuni is always got over as a bastard
sort of Dittany. Also, what species is the Man-
drake, so common of mention by our early poets ?
Bentham has merely, " Mandragora, an exotic " ;
and your notice of the " Rolls MS." says "White
Bryony," a name not found in Bentham or Sowerby's
" Wild-Flowers." The glossaries, of course, afford
no help as to species. The English Dialect Society
have long promised us a book of "Plant names,"
under the most competent editorship, but the long
■delay makes us despair of it in any reasonable
time. — Henry F. Bailey.
Aquarium Matters. — Your correspondent Ed-
ward Step seems to have been lucky in hitting upon
a mode of keeping aquaria without difficulty, and I
am glad his system gives him satisfaction ; but I
think, if his washing-tub arrangement is correct,
most of the readers of his letter, with any knowledge
•of the subject, will think that he is deluding himself
with the idea that he is keeping aquaria, whereas he
is only keeping a small ditch ; for, that water can be
kept clear and inodorous for any length of time in
.a tub in which there are all sorts of aquatic plants,
.animals, insects, &c, I much question ; and that such
fish as dace, roach, perch, trout, &c. will live many
days in such water, my experience makes me deny.
The tub, mud, and water arrangement may do very
well for Edward Step if he only wants to keep objects
for the microscope, but to fill a vessel with mud and
water, and to place in it animals, fish, snails, insects,
and plants, irrespective of quantity or selection, and
let them fight and devour each other until they have
•established what he calls the balance of power, is
about the queerest way of keeping aquaria I know of.
It is r.cting upon such injudicious advice that has
made aquaria-keeping so rare in private houses.
People have been told that they have only to get
a vase or glass tank, fill it with water, put
some mud or sand at the bottom, place water, plants,
snails, fish, caddis-worms, reptiles, beetles, or any-
thing they find in a river, ditch, or pond in it, and
they will at once have a thing of beauty and a joy
for ever : they do so, and, after weeks of patient
waiting, they find they are keeping a mass of slimy
decaying plants, dead fish, &c, in water which the
wife or housekeeper declares is not only very odorous
but very dangerous. If fresh- water aquaria are to
be kept to be of any use or pleasure, they must
be so upon a judicious selection of situation, plants,
and live stock, which live stock are most accustomed
to still waters, and if your correspondent had had
a little more field and river experience before setting
up his tub, he would, perhaps, have discovered that
there are plants of the river, pond, ditch, and stream;
and fish, mollusks, &c, of the same, each having its
own habitat in which it will flourish. — Ben Plant,

deep-sea fishes and crustaceans also emit a pale
phosphorescent light, and, illumined in the darkness,
are enabled to prey on each other, a marvellous in-
stance of adaptation to natural surroundings.
The John Dorey [Zeus faber), like the Angler, is
also somewhat of a rarity in captivity, hut the speci-
mens exhibited in this Aquarium continue to thrive
admirably, feeding on the shoals of live sprats and
sand smelts sharing their abode. All the tanks, well
stocked with healthy inmates, are in excellent order,
testifying conclusively to the efficient care and atten-
tion of Mr. Lawler, resident curator and naturalist.
The sea-lions {Otaria Stelleri) are again on view, the
lioness having completely recovered from her late
serious indisposition. Two young female seals {Plwca
vitulina) now share the new seal-pond in the con-
servatory with the two males of the same species, old
inhabitants of the Aquarium. A fine specimen of
the curious Japanese Salamander {Triton Sieboldi),
measuring nearly 3 feet, has recently been added
to the collections. It is thoroughly acclimatized,
existing in fresh water at a normal temperature, and
feeding principally on raw beef and liver, which it
seems to prefer to the species of fresh-water fishes
offered alike for its acceptance. It is a sluggish,
weak-limbed reptile, covered with a dark-brown skin,
the head and throat being thickly dotted with the
glands so characteristic of the "warty newts," and
the large pores serving to distribute the viscous matter
shed over its exterior are distinctly visible. The
mouth is remarkably capacious, and the eyes so
minute and dull as to be hardly perceptible. Repre-
sentatives of the genus were first brought to Europe
by Dr. Von Siebold, who discovered them inhabiting
a lake on the top of a basaltic mountain in Japan.
It is the Sieboldtia gigantea, Bonap., and the Sala-
mandra maxima, Schelegel, but is now classed with
the Tritons, and bears a close resemblance to the
gigantic American newt (Mcnopoma) of the Alleghany
mountains, the generic difference consisting chiefly
in the permanence of the gill-slits in the one form,
and their disappearance in the adult Japanese species.
It is also interesting as being nearly allied to the huge
fossil salamander (Andrias Scheuchzeri), from the
fresh-water Miocene beds of CEningen, in Switzer-
land, so famous as the "Homo diluvii testis" of
Scheuchzer, who long maintained it to be a fossil
man, and therefore an indisputable relic of the
Noachian deluge. His views were put forth with
such persistence as to be accepted by many naturalists,
until the illustrious Clavier finally settled the contro-
versy. He obtained permission to remove the matrix,
and having previously made a rough sketch of the
animal he expected to find, proceeded to lay bare
some hidden portions of the specimen, and thus irre-
futably proved, in the presence of a group of asto-
nished spectators, that the much-vaunted fossil-man
was merely a gigantic salamander.

THE HABITS, FOOD, AND USES OF THE
EARTHWORM.— No. II.
By Professor Paley, M.A.
1. TN the first place, they bring up fresh under-
-L earth to the roots of the grass : this useful office
is done on a much larger scale by moles, which live
on worms, and throw up those heaps of well-crumbled
mould which are intended to relieve at intervals their
tunnels, made a few inches below the sod. We
know that farmers, who generally dislike what they
regard as superfluous trouble, and rarely possess much
scientific information, will pay a mole-catcher con-
siderable sums for the destruction of this harmless
and even useful creature, which they seem to regard
as a kind of rat ! If they would pay a tenth part of
the money to send into a meadow a small boy with a
small rake, and get the mole-heaps spread over the
grass, they would get a third more in their crop of
hay.
2. All grazing animals eat a great quantity of
earth. They cannot avoid swallowing the worm-
casts, and they like to do so. Earth seems comfortable
to their insides, and it is certain that they enjoy it.
I used to ride a horse which, being regularly fed on
hay and corn, and not turned out to grass, pined for
a little dirt. Finding out this, I sometimes let him
go to a hedge-bank, slackened the rein, and watched
him scoop out with his tongue earth enough to fill a
pint-pot. This, I think, is the reason why a horse so
often stirs up the mud in a pond with his hoof be-
fore drinking. Many horses will paw the water even
when passing a clear stream, giving their riders the
fear that they want to lie down in it. Some races of
American Red Indians eat earth. The fact is attested
by Humboldt and others. It is said that the Jamaica
negroes will do this when other food is deficient or
not procurable.*
3. Seeds of trees are dragged by worms into their
holes, and there germinate. This is most commonly
the case with the seeds of the ash and the sycamore,
both of which have their winged appendages set
slightly on one side, like the sails of a windmill, or
the screw-propeller of a ship, so that they are carried
by the wind and fall aslant at some distance from the
trees. I have repeatedly drawn both of these seeds
out of worm-holes, after they had begun to germinate.
The fact is established by the carrying down of seeds,
strewed on the surface, by worms kept in a pot.
There can be no doubt, therefore, that it is one of
the provisions of nature for the propagation of
vegetable life.
If you examine a worm-cast, you will find that it is
composed partly of the earth ejected from the hole,
in small clods, slightly coherent (probably from some
admixture of the slime), and partly of excrementitious
matter. The latter is easily distinguished by its

granular and mammillated appearance, somewhat re-
sembling mouse-dirt. It does not seem to be thrown
out of the hole mixed with the rest of the earth, but
it is deposited separately, often in considerable
quantity. If you crumble it when dry, you will find
it full of vegetable fibre, which has the appearance of
undigested moss, or small blades of dried grass,
curiously rolled up in rather hard little pellets, which
do not easily crumble with the rest of the earthy
excreta. It is clear, therefore, that the dirt of the
lob -worm is part vegetable, though the greater part
of it is simply earth. If the excreta are dissolved in
water, the vegetable debris is still more easily col-
lected on the top of the muddy sediment. It is not
surprising, from the nature of their food, that the
richest earth is generally most full of worms. They
are scarcely ever found in digging in sand or gravel,
and this is the reason why you so rarely meet with
mole-hills in sandy or pebbly soil ; viz., because these
clever little creatures find out that worms are not lo
be had there for their trouble in boring. How the
worm ejects these little pellets on the outside it is
perhaps impossible to say. The head is always pro-
truded first from the hole ; can it be that the pellets,
after being discharged, are conveyed to the surface
by some special process ? Or does the worm emerge
entirely from its hole during the night ? The excreta,
however, are never found apart from the worm-cast
covering the hole.
I enclosed three large worms in a flower-pot of
moist earth, covering it so as to prevent their escape,
and occasionally sprinkling a little water on the surface.
I found, as I had expected, the next morning that a
hole had been bored, opening to the surface, and the
bits of earth were thrown out, but not a particle
of the excreta. I then placed some leaves, with
bits of stick and string, on the surface of the pot,
in order to see if they would be used as a plug for
the hole.
I was desirous also to ascertain if the worm came
to the surface to feed, or if it in any way disturbed or
fed on the leaves, the positions of which and their
condition I took note of. I found that the bits of
string and the leaves had been all moved, and some
of them drawn into the aperture of holes they had
opened against the sides of the pot ; also that the
leaves were in part nibbled away, if one may use
such a term of a creature which has only some power
of sucking up or sucking off. It seems certain then
that worms swallow both earth (rich earth in pre-
ference to poor or sandy earth) and also fibrous
vegetable matter.
Every effect that the worm leaves visible on the
surface seems done at a time when its enemies, the
birds, are not abroad. How a blind creature can tell
night from day seems surprising ; possibly the warmth
of the sun, or the dew at night may serve it for this
end. By keeping one or two worms in a flower-pot,
I once or twice found one partly exposed. It was
! passing, by peculiar jerks made, with intervals of rest ,
from one hole into another. From this I suspected
that, as in a rabbit-warren, the same creature has
several holes communicating with each other under
ground.
To ascertain this, after keeping the worms fo
some time in a flower-pot, I let them escape, and by
drying the earth I was able to dissect it so as to
expose all the galleries and passages. I found these
very numerous, and towards the bottom of the pot
containing portions of leaves which had been drawn
down for food. Grains of wheat and other seeds had
been carried down to the bottom, and it seemed to
me that the worms had fed on the tangled roots which
these seeds had sent out through the whole thickness
of the earth. The excreta in some cases were adhering
to the sides of the pot. I think they must have some
way of conveying it or pushing it out of their holes,
as birds are said to eject the dirt of the young nest-
lings. I think, also, that it is got rid of as soon
as deposited. For, though worms are very shy of
making themselves visible by day, it is common to
find worm-casts so moist and fresh that they have
evidently just been thrown up. This is the case with
mole-heaps ; but I never saw, and I never met with
any one who could say that he had seen, the earth
actually being thrown up. The mole, like the worm,
is evidently very sensitive to the tread of a foot.
Both remain quiet when they feel the vibration of
the ground.
Worms by no means invariably draw into then-
holes leaves or bits of sticks, or cover them over with
pebbles. The reason of their doing so at all is there-
fore the more obscure, since it is not a necessity. Very
often the hole is marked only by the little heaps of
earthy excreta, and however carefully you remove
these, you will find the hole itself is completely
stopped. They nibble off the ends first, and then
pull the remainder down lower, till little more than
the stalk and mid-rib is left. And a little observa-
tion will show that the leaves have really been
devoured, and have not rotted away in the moist
earth. This fact I ascertained to a positive certainty
by repeated supplies of diy leaves put into the flower-
pot, the whole being clean eaten up except short por-
tions of the stalks. It seems then that a very large
part of the decaying vegetable matter in gardens is
consumed by the numerous lob-worms, for they are
greedy eaters, though they seem to do no harm to
growing plants, even if they do eat some of the fibrous
roots. In this respect the worm resembles the mole
and the dung-beetle, which never leave the hole to the
upper surface open to the air, as most of the burrow-
ing animals do.
Nevertheless, it is certain that worms do feed on
leaves or bits of stick drawn into their holes. My
grass-plot in late autumn quite bristled with the tufts
of fallen willow-leaves (the weeping willow), but in a
few weeks they had vanished, entirely consumed by
i56
HA RD Wl CKE 'S S CIENCE - G OSSIP.
the worms, which had drawn them there for food. I
laid about a dozen of these dead willow-leaves on the
top of my flower-pot, and in a day or two they were
all drawn in (always with the stalk uppermost), and
so gradually devoured. I put in a fresh supply, and
one evening, on gently removing the cover, I detected
a worm with its head affixed, or stuck by the slime,
to one of the leaves. It did not stir in the least, and
seemed perplexed by the stalk of the leaf resting
against the side of the pot. But in the morning the
clever creature had turned it round, and there was the
stalk-end sticking up in the worm hole ! It had
turned it completely round, and whereas it had lain
like a bar across the hole, it had contrived to pull in
the narrow end. All this is evidently done by the
creature feeling the position of the leaf. But to turn
it when it is the wrong way is a process that resem-
bles a kind of low reasoning rather than mere instinct
— if, indeed, we have any right to regard the two
motives of action as essentially distinct.*
Not only leaves were thus drawn in and devoured,
but grains of wheat, canary, and rape-seed, sprinkled
on the top of the earth in the flower-pot, were gra-
dually carried down, and soon entirely disappeared,
so that after a few days not a single seed was to be
seen. I tried bits of stick, bread-crumbs, scraps of
ginger-bread, and biscuit, but they were not much
noticed, though the sticks were generally moved.
After a few days, the seeds came up, thus affording a
pretty conclusive proof that one province or function
of the earth-worm is to promote the growth of plants
by burying seed which might otherwise perish, or be
picked up by birds.
In the above purely popular account of the earth-
worm, no attempt has been made at a scientific descrip-
tion.
The anatomy of the earth-worm, and the organs
and process of reproduction, which are extremely
curious, are very fully explained in an elaborate
paper by Sir Everard Home, Bart., in the " Philoso-
phical Transactions of the Royal Society" for 1S23,
part 1, pp. 140 — 151, illustrated by four plates,
xvi. — xix., containing magnifieddiagramsof the various
internal parts. f These are, to enumerate them briefly,
a head with a distinct mouth, having some serrated
apparatus, not very unlike teeth, a brain (cerebral
ganglia), spinal cord, artery, with six lateral lobes or
cells on each side, containing red blood, perhaps
equivalent to a series of hearts, an oesophagus, crop,
gizzard, intestinal canal, and anal aperture. The
creature is divided through its entire length into com-
partments, containing eggs enclosed in membranous

an elephant, his turning sideways a log, which he was carrying
balanced across his tusks, so as more easily to make his way
through the trees.

rather darker colour. This is connected with the
generative process, and appears to have given rise to
the popular opinion that a worm cut in two will ' 'mend

which is felt on handling a worm arises from minute
bristles which grow out of the rings, and doubtless
assist the creature in its movements. The slime
exuded is not nearly so tenacious as that of the snail
or the slug, but it probably facilitates the progress of
the worm through its labyrinthine home, and it ap-
pears to impart some solidity both to the walls of the
passages and to the substance of the excreta.
THE DEVELOPMENT OF SPECIALLY
ADAPTIVE APPLIANCES IN PLANTS.
THERE is perhaps no branch of scientific know-
ledge which has received greater stimulus of
late years than that part of physiological botany which

refers to the colours of flowers and the origin of their
forms. The observations of Drs. Darwin and Miiller,
of Sir John Lubbock, and others, have supplied
material for modern scientific thought to explain the
whole scheme of vegetable creation, and attempt is
now even being made by some to connect with the
development of vegetable life the colour sense of the
animal world, including that of man himself.
A writer in Cornhill Magazine for May has
striven to show that all irregular-shaped flowers,
especially those which combine with colour attractive-

ness, sweet-scentedness, such as the Labiate?, are the
most recently evolved, and that with this development
have been correlated the colours of insects. Also
similarly is it so in the case of coloured fleshy fruits
and the development of the colour sense in the higher
vertebrates to suit their frugivorous tastes. And it is
interesting to remark that these higher stages have
been observed to be intensified even in historic
times, as in the case of the human race ; for the mere
mention of colour itself — that is to say, in any sense
of appreciation — is entirely absent from the most
ancient literary works which we possess.

BOTANICAL WORK FOR JULY.
SUPPOSE any one absent from England for
many years, were to be landed, or placed on
our shores about the early part of summer, but to be
totally ignorant as to the month of the year, rambling
along the lanes and fields, and seeing a profusion of
the various though elegant species of Veroniac, he
would naturally say, "This must be the month of
May ! " So, in like manner, a little later in the season,
finding the willow-herbs scattered here and there
with a lavish hand— would he not exclaim: "This
is July!"?
Our subject this month then must be to work up
the willow-herbs. We trust we shall make them so
simple and plain, that our meaning or descriptions
cannot be misunderstood, but make a large addition
of new forms to our herbaria of curious and distinct
varieties, which have hitherto been passed over : —
Section i. Corolla irregular, "wheel-shaped {rotate).
In this section we have only one British species,
the handsome Rose-bay, Epilobium august/folium,
Linn., with its garden variety, E. brachycarpum,
Leight.
Section 2. Elowers regular, campanulate, or
fun n el-shaped.
Note. — By carefully observing the characters of
the following divisions, it will be easy afterwards to
recognize the different species and varieties, without
having the least doubt as to thier identity.
Division i. Stems terete, stigma \-cleft.
1. Epilobium hirsutum, Linn. Whole plant very-
hairy. L. opposite, oblong-lanceolate ; flowers large,
showy, rose-purple, often \ in. diameter ; the four
lobes of the stigma curled backwards (revolute) ; buds
erect.
2. E. paivifiorum, Schreb. (E. molle, Lam., in
Fl. des Environs de Paris). A much smaller plant
than No. 1. Stigma lobes short, not bent back; L.
alternate ; flowers i in. diameter, rose-purple, more
or less pubescent.
Var. a. E. rivulare, Wahl. Often quite glabrous
or smooth ; not unfrequent on the borders of shallow
brooks.
Var. b. E. intermedium, Merat. Covered with
fine silky hairs. L. all alternate. Frequent by
stagnant ponds, &c.
Yar. c. E. molle, pubescent. L. in threes, verticil-
late (whoiied) ; more rare than the above. By the
river at Kew.
3. E. vwntanum, Linn. L. quite smooth, except
veins, ohXow^-ovate ; buds drooping ; flowers pale
purple.
Var. a. E. gracile (Fl. des Environs de Paris). A
smaller plant, and much branched. L. oblong, on
short stalks ; flowers all drooping gracefully.
Var. b. E. verticillatum, Thuret. L. small, whorled
in the lower part of the stem.
Another variety, though probably not a permanent
one, with white flowers, is occasionally found in
plantations.
4. E. lanceolatitm, Sebast. -Very rare. L. stalked,
lanceolate, narrowed to an entire base ; buds droop-
ing, ovate.
Division 2. Stem with raised lines, or 2 to 4
angles, stigma entire, club-shaped.
5. E. tdragonitm, Linn. Stem with 4 unequal
angles ; L. strap-shaped, smooth, stalkless ; buds
erect. A much-branched species.
Var. a. E. obscurum, Schreb. L. tapering from
a rounded base, lanceolate, not shining above. We
regard this as a true species, as do most continental
authorities. ( Vide Gren and Godron.)
6. E. paluslre, Linn. Stem 1 foot, simple, with 2
lines of hairs, seldom branched. L. mostly opposite,
downy on upper surface, smooth beneath, except
midrib, lanceolate, with -wedge-shaped base. Flowers
small, in leafy clusters.
Var. a. E. pubescens, Cuss. Whole plant covered
with downy hairs, and densely branched.
Var. b. E. ligulatum, Baker. L. toothed ; style
simple ; partakes much of the characters of palustre.
In this month we must also keep a look-out for the
Loosestrife, Lythrum Salicaria, Linn. Being so well
known, it is not needful to describe it particularly ;
first , let us observe, Hooker, in ' 'S tudent's Flora, "notices
two varieties growing by the Thames, at Kew, — a long-
styled and short-styled plant. These have recently
attracted considerable attention, by observers of the
modes of fertilization, and justly so, for, even viewed
in this light, they are full of instruction.
In the Floras of France, three varieties are enume-
rated. Having occasionally detected these, we mention
them with confidence, — it may throw a new charm
upon an old face to many of our readers.
1. L. alter nifolium. Floral leaves alternate (rare-
ment toutes les feuilles alternes — Fl. des Environs de
Paris). We have not seen the whole of the leaves
alternate; as here described. Flowers pink.
2. L. verticillatum. L. in threes, verticillate,
styles long. A smooth plant, slender, with narrow
leaves. Flowers bright or pale pink.
3. L. pubescens. Style short, a large coarse plant.
Flowers dark dull-purple, very hairy (Plante tres-
pubescente, or plant very pubescent). Fl. des Environs
de Paris.
The Sundews (Drosera) are becoming just now so
conspicuous that we may be pardoned by a passing
though brief reference to one of the species. Probably
Drosera oboz>ata (Mert. et Koch) has hitherto attracted
very little attention, from the fact, it is supposed to
be a hybrid betwixt D. anglica and D. rotundifolia,
but any one knowing the true plant, and observing
its habit, style, and capsule carefully, will never so
regard it.
D. obovata, Mert. and Koch. L. truly oboz'ate,

broader at the summit than the type,

MICROSCOPY,
Diatomaceous Material. — Mr. Clark, the Se-
cretary of the San Francisco Microscopical Society,
announces to diatomists that the Society is now
enabled, by the kindness of the State Geological
Survey, to offer return exchanges of the Pacific Coast
diatomaceous deposits on receipt of any valuable
microscopical material.
The Quekett Microscopical Club. — We have
received the latest issue of the Journal of this vigorous
society, containing a description by Mr. J. G. Waller,
of a new British sponge, of the genus Microcionia ;
a paper on "The New Autographic Process," by
Mr. A. Cottam ; an abstract contribution by M. M.
Hartog, B.Sc, on "The Investigation of Floral
Development"; and a " Record of the Proceedings
of the Meetings of the Club."
A Wet Process of Mounting in balsam is well
described by Mr. Stokes, in the May number. I have
for some years used a similar method, and which for
large and whole insect preparations I prefer. It is diffi-
cult to set out all parts of an insect, and at once apply
balsam without again disarranging your work. I there-
fore proceed thus : — The object having been sufficiently
soaked in potass to soften it, and washed well in
distilled water and freed from dirt, &c, I place it for
a minute or two in alcohol, then lay it out on a piece
of glass in a little alcohol, cover with another piece,
press and tie with cotton, and throw into a bottle of
alcohol — the longer it stays here the less likely to
alter form, — take it out after a day or two, put into
turpentine and again brush ; it may be then mounted
after a few minutes' soaking in the turpentine, but I
generally prefer to tie it up again and throw it into
turpentine for a few days. To mount, lay object on
slide on some balsam (liberally), and cover with thin
glass, which hold down lightly with clip of some kind;
boil, until a portion of the balsam around the cover,
taken on the end of a needle, is tolerably stiff.
There may be very many bubbles, but if they only
arise from vapour of turpentine, and the balsam is
not too hard, they will all go out in a few days.
The boiling need be for a very short time, and a little
practice will make perfect work. It is the simplest
method of balsaming I know of, much more easily
managed than damar. — An Old Mounter.
Canada Balsam in India.— An experience of
twenty years enables me to give a satisfactory answer
to the inquiry of Ff. F. Blackett as to the heat-
resisting power of Canada balsam in India. I have
brought back with me many specimens, mounted in
that medium, which I took out with me twenty-five
years ago, and they are as perfect as ever they were.
My experience of mounted slides is as follows,
though it may possibly not accord with that of others.
Canada balsam stands well, and so (and I was
much surprised at the fact) does sealing-wax varnish
as a surrounding cement ; though much, no doubt,
depends upon the quality of the sealing-wax. The
black asphalt cement is apt to run in under the thin
glass. I have some specimens surrounded with this
material entirely spoilt, while a few have stood well.
All chemical preparations are spoiled by the climate.
— C. S. P. Parish.
Plant-Crystals. — Mr. Hammond's paper, in
the June number of Science-Gossip is likely to
lead to valuable microscopical work. Now, micro-
scopists need no longer be advertising for good
materials for the preparation of interesting slides, for
they everywhere surround us, in our walks through
the green lanes and excursions to the conservatory,
and to the shops of the druggists. In the latter may
always be had guaiacum bark and quillaja, in both of
which the long crystal prisms exist in great abundance
and beauty ; while the short prismatic crystals are
very plentiful in most of such common plants as the
Leguminosce, and in the testa or seed-skin in the Elm,
Black Bryony, and Scarlet Pimpernel. All these
crystals are admirably fitted for experiments on the
polarization of light. The sarsaparilla of the drug-
gists affords true raphides ; but these do not polarize
light well, nor do the cystoliths or other sphrera-
phiclcs. All of them are figured either in Science-
Gossir, May, 1875, or in the Monthly Microscopical
Journal, December, 1873 ; anc^ ** 1S understood
that Professor Lionel Beale will devote two plates to
all these interesting crystals in the forthcoming new
edition of his great work, entitled "How to Work
with the Microscope." — G. R.

ZOOLOGY.
The Hemipterous Fauna of St. Helena.—
At a recent meeting of the Zoological Society of
London, a communication was read from Dr. F. Bucha-
nan White, entitled " Contributions to a Knowledge
of the Hemipterous Fauna of St. Helena, and specu-
lations on its origin." In the first part of his paper
the author, after briefly noticing what was known
with regard to the Fauna and Flora of that remote
and interesting oceanic island, and mentioning the
various theories that had been brought forward to
account for their origin, discussed the difficulties of
the animals, and argued that they had evidently been
derived at a remote period from the Patearctic Region
by way of Madeira, the Canaries, and the Cape de
Verde Archipelago. In the second part of his com-
munication Dr. White described the Hemiptera
collected in St. Helena by the late Mr. T. V. Wollas-
ton, during the recent visit of that naturalist to the
island. The collection included thirty species, of
which five were probably introduced ; one appeared
to be indigenous, but seemed identical with
European species ; and the remaining twenty-four
were regarded by the author as new and peculiar to
the island. Seven new genera and one new sub-genus
were created for the reception of ten of the species,
the rest, with one exception, being referred to
European genera.
Testacella haliotoidea in Jersey. — This
slug, though recorded as occurring in the sister isle
of Guernsey, seems not to have been reported from
this island. On the 21st of April last, about 9 a.m.,
I observed a specimen crawling at the foot of a dry
bank, after rain. It carried a prominent oval lami-
nated shell, of an ashy- white colour, about \ an inch
in length by \ of an inch in breadth, just in front of
the hinder extremity. But it appears that an intel-
ligent observer, R. Macdonnell, Esq., by whose
kindness I have since seen a second specimen, has
noticed it occasionally, for several years, in his
garden, about half a mile from the other locality.
Whether it is indigenous in Jersey, or imported from
France with soil, I must leave to those who, unlike
myself, are learned in the history of mollusca. —
Martin M. Bull, Jersey.
The Cuckoo at Night. — On the 24th of May
I heard the note of the cuckoo at 2T5 a.m. The
night was very dark, and it was raining heavily, yet
the cuckoo was singing as loud and as cheerfully as
it would in the daytime. Is it usual for the cuckoo
to sing during the night? — A. M. McA., Stoke-on-
Trent.
Irish Wolf-Dog. — Lord Talbot of Malahide
formerly had a clog said to be the Irish Wolf-dog ;
he probably can give "L. M." the information he
requires.
BOTANY.
Meyenia erecta. — It must have been obvious to
Science-Gossip readers that the name "Mergenia
erecta," which headed a paragraph in the June num-
ber, page 139, and which had reference to fertiliza-
tion adaptability, was a misprint for the above.
Acanthacece, to which natural order this plant be-
longs, approach Labiate and Verbenacere, Scro-
phularineae and Bignoniacece in the irregular anisos-
temenous corolla : they differ from the latter two
orders in the aestivation of this whorl, and by the
absence of albumen. All these groups of irregular-
shaped flowers are specially adapted for insect fer-
tilization, and, as regards the favoured theory of the
origin of species, they doubtless constitute the last
link in the developed series of flowering plants. I
am inclined to suggest that there is a field open in
connection with the investigation and study of the
floral structure of these groups, and that special
attention devoted in this direction will be attended
with fresh interesting discoveries. — George Newlyn.
Epilobium ANGUSTIFOLIUM (Rose-bay Willow-
herb). In " Flora Lapponica," Linnasus describes the
hut of the Laplander encircled with the tall stem-,
and elegant blossoms of this species ; he goes on to
state they in state emulate the palaces of the gods.
The Swedes call it Himmelgnvs, or " herb of
heaven." The only true wild form found in England
is the E. macrocarpum, Steph., whilst the one often
found in cottage-gardens is the E. bracliycarpum of
Leighton's " Fl. Shropshire " ; they are quite distinct.

Destruction of Rare Plants. — As this sad
work is still going on, Mr. E. D. Marquand deserves
the thanks of all botanists for his judicious remon-
strances, in the June number of Science-Gossip,
against the rooting out of the New Forest such
interesting species as Spiranthes ccstivalis and Pul-
monaria angustifolia. It would be a libel to attribute
such wanton destruction to botanists, since it is done
by mean dealers. But it unfortunately happens that
the destruction is too often encouraged under the
pretence of science, especially by sorae of our pro-
vincial societies offering rewards for the best col-
lections, as if mere collectors had any pretence to be
regarded as botanists or zoologists. If the rulers of
such societies had any intention of encouraging, by
rewards of money or otherwise, the promotion of
botanical or zoological science, that might be more
easily and effectually done by proposing investigations
of the species and intimate structure of common
plants and animals. For example, the species of the
Wild Roses, Brambles, Willows, Sedges, Grasses,
&c. , would afford excellent exercises ; and so would
the examination of the intimate structure of the
glands, hairs, pollen, and distribution and significance
of raphides and other plant-crystals, &c. It is really-

aggravating that Mr. Marquand should have been
called on to protest now against a crying evil ;
especially as it has long since been denounced by
Professor Gulliver and others in Nature, May 22,
1873, and in the Nineteenth Report of the East Kent
Natural Histoiy Society ; and all this about the same
time that Professor Babington and other eminent
botanists were protesting strongly but ineffectually in
the same cause. — Q. F.
A Glass-eating Lichen. — My friend Mr. John-
ston-Lavis's lichen seems probably of more interest
than the unpainted surface of much old glass. If
this lichen — for lichen it very probably is — really has
the power of dissolving glass, it is certainly of the
very deepest interest. I quite agree with the disco-
verer in setting aside the "workman" theory ; but I
much regret that the extent to which the figures are
magnified is not given, the method of drawing not
stated, and the "various re-agents" used to remove
the growth not named ; for in Mr. Johnston-Lavis's
paper I see no evidence that would make me attribute
a solvent power equal to that of hydrofluoric acid, to
thislichen, ratherthan believeinthe simpler hypothesis
that it is filling up by its growth previously existing
holes. I hope my friend will prosecute this inquiry,
and produce some more decisive evidence one way or
the other. — G. S. Boulger.
Old Plant-Names.— In answer to Mr. Henry F.
Bailey, I may say that Dittany does not occur in
Turner's " Libellus de re Herbaria " (1538). In Ge-
rard's " Catalogus " (1596), Dictamnum crceticum and
fraxindla are mentioned, and in the second (1599)
edition, the former is called ' ' Dittanie of Candie," and
both "Fraxinella Bastard Dittanie" and "Fraxinella
altera, Great Bastard Dittanie," are recorded. The
Dictamnum crceticum is described on p. 651 of Ge-
rard's " Herbal" (1597), and is identified by my friend
Mr. Benjamin Daydon Jackson, editor of the "Cata-
logus" and "Libellus," with Origanum dictamnus
of Linnaeus. Fraxinella is described on p. 1065 of
the "Herbal," and is, according to the same high
authority, Dictamnus albus, L., whilst F. altera is on
the same page of the "Herbal," and is Dictamnus
fraxinella of Persoon. Dictamnus belongs to the
Rue tribe. It is remarkably inflammable, owing to
its oil-secreting glands. D. albus is now commonly
known as Dittany. Origanum belongs to the Labi-
ates, and our Marjoram is a species of this genus.
On p. 61 of the " Herbal," and in both editions of
the "Catalogus," Gerard also mentions " Pseudo-
dictamnum, Bastard Dittanie," which Mr. Jackson
makes Ballota pseudo-dictamnus of Bentham. Garden
Rue is, and was in Gerard's time, Rula graveolens,
though then known as Ruta saliva. I am not at all
sure about the Mandrake, but the probabilities seem
in favour of a solanaceous plant, rather than the
White Bryony, which is the popular name by which
Bryonia dioica is distinguished from Tamus communis,
the Black Bryony. Tournefort named the genus of
Solanacea?, now known as Mandragora, of which the
species officinalis is commonly known as the Man-
drake, "The insane root which takes the reason
prisoner," is often said to be the Dwale, or Deadly
Nightshade ( Atropa Belladonna). I may refer
Mr. Bailey to the Rev. H. N. Ellacombe's " Plant-
lore of Shakespere," an excellent work, which I
have not by me at present, and I may perhaps also
take this opportunity of calling attention to the exist-
ence of a "Turner Printing-Club," for reprinting
early works on British botany, under the superin-
tendence of Mr. B. D. Jackson, of 30, Stockwell-
road, S.W. In Gerard's "Catalogus," and the
"Herbal," p. 274, the Brinjal, Aubergine, or Egg-
plant of Asia, Solarium Melongena, L., is mentioned
as Mala insana, Mad or Raging Apples. I take
this opportunity of publishing, for the justification of
our early authors, their meaning in the various Maiden-
hairs. The true Maidenhair is Adiantum capillus-
veneris. Possibly the foliage of Thalictrum minus,
the Lesser Meadow Rue, was sometimes mistaken
for it. The common or English Maidenhair is As-
plenium Trichomanes ; the Black Maidenhair is A spl<-
nium Adiantum-nigrum ; the White Maidenhair is
Asplenium Rula-muraria, the Wall-rue Fern ; and
the Golden Maidenhair is the moss Mnium kygrome-
tricum, also called Little Goldilocks. The Goldilocks
is Ranunculus aurlcomus. — G. S. Boulger.
Bible Plants. — An interesting little volume with
this title, by John Smith, ex-curator of the Royal
Botanic Gardens, Kew, has just been published by
Hardwicke & Bogue. One plant, however {Lycium
EuropcBiim), appears to me calculated to mislead ; it
is described (page 207) as "a rambling, prickly shrub,
well "known in this country as Boxthorn or Tea-tree,
and often used for covering garden-seats, arbours,
and the like, and is a hedge-plant in Palestine."
At plate 9 is a figure of the plant, marked C, which
is no doubt correct as it is found in Palestine, but
bears no resemblance to the tea-plant so well known
in England. Mr. Baker, curator of the Royal
Herbarium at Kew, says, "it is Lycium Barbarum
not Europttum that is commonly cultivated, but they
are very near to one another, and the genus is in a
great muddle and wants re-monographing." He
says, "The Lycium of Syria is L. vidgare of Lin-
nceus, L. Mediterraneum of Dunal, and copiously
spiny when wild, but loses its thorns when under
cultivation." The Lycium Mediterraneum, Dunal,
D.C. Prod. ; Lycium Furopeum, Linnaeus, Mant. 47 ;
Desf. Atl-kock syn., is described in the "Flore de
France," by Grenier et Godron, as with leaves a little
fleshy, oblongues-obovees, insensibly attenuate in a
short petiole, common on the whole littoral of the
Mediterranean. No one looking at the figure at
plate 9 could suppose it represented the tea-shrub, so

well known in England. The plant is stated in the
" Treasury of Botany " as being known as " the Duke
of Argyle's tea-tree," the leaves being recommended
for use in the place of tea, a piece of advice not
generally acted upon it would seem. The leaves
appear in the figure so extremely diminutive that they
never could have been used as a substitute for tea.
There appears, therefore, to be some confusion ; the
plant in the figure should have been referred to as
the Lycium Europceum of Palestine, but altogether
unlike the tea-tree, sometimes found in a semi-wild
state in England, where it is so well known as the
tea-tree. Mr. Baker says he has not seen the Bible
plant, and of course he can give no opinion as to the
figure in plate 9. — T.B. IF., Brighton.
Definite and Indefinite Inflorescence. —
Sir J. E. Smith thought the distinction of not much
importance, on account of the difference found among
the species of Allium in the order of expansion of
their flowers. Nor did Professor Lindley seem to
recognize the distinction as of primary importance,
for in this little work on Descriptive Botany, the
spike, the raceme, and the corymb are represented
by figures each terminated by a central flower. Such
a central flower may indeed be found in the spike
of Agrimony, the corymb of the Pear, the umbel of
the Apple, and the panicle of London Pride. After
noticing such facts, one may be pardoned for enter-
taining a doubt as to the existence of any form of
inflorescence strictly indefinite, i.e., incapable of pro-
ducing a terminal flower on the axis of inflorescence,
or a lateral bud below the flower upon its pedicle.
Such a mode of inflorescence does, however, seem to
be in the orders Crucijine and Primnlacea, and it
may be in other natural orders, only subject to such
exceptions as belong to the province of teratology.
For nearly twenty years I watched the inflorescence
of cruciferous plants before finding an indisputable
case of a flower-stalk with a flower on the summit
and another below it on the side. This was on one
of the ramifications of a much-branched stem of a
perennial stock which flowered last year, and of
which a note appeared in Science-Gossip of July,
1877. This year a similar phenomenon has appeared
on another plant of the same kind. Foliar prolifi-
cation of the inflorescence is, however, much more
common, though I have observed it only in perennial
plants, not in annuals or biennials. The stem of the
watercress will sometimes grow beyond the series of
flowers on its sides, producing leaves above the raceme
as freely as below it. Cardamine pratense may be
occasionally found with a tuft of leaves on the top of a
flowering stem, and I have now in bloom in my garden
a stem of a wallflower which bore flowers, produced
pods, and ripened seeds last year. Between the two
series of flowers came a tuft of leaves, and this year
there is a branch above the mortal remains of last
year's pods, which, as well as the main stem, has
blooming flowers. If the stem be not exhausted too
much to ripen seed, I will allow it to do so, that I
may see if such a variation is hereditary. It thus
appears that in cruciferous plants median prolifica-
lion of the inflorescence is always foliar, median
prolification of the flowers floral. — John Gibbs.
Orchis-hunting in Surrey.— Surrey is to
me associated with many delightful rambles, and
none of them more so than those I have deno-
minated "Orchis-hunting." Living at that time
close upon the North Downs, I was able to make
acquaintance with some of the chalk-loving species
of theJDrchidacere seldom met with now, especially
as I am at present located amongst the Red Sandstone
of Devonshire. My "happy hunting-grounds" at
that time consisted of the parish of Ockham as a
centre, from which I made pedestrian excursions into
the surrounding neighbourhood. Most of the species
I find referred to in my notes were found within some
five or six miles of what was then Ockham Middle-
Class Schools. In the moist meadows around, and up
what everybody knew as the "Rides," were found
very plentifully, 0. masatla, O. maculata, O. latifolia,
ATeoltia Nidus-avis, and the Listera ovata. (The
Adder s Tongue Fern was very plentiful in a meadow
by the side of the Rides.) In a meadow near a pond
called the " Sheepwash," I came upon the Habenaria
bifolia, and on several occasions 0. niorio. It was,
however, by walking some few miles and getting upon
some of the chalk ridges that I made acquaintance
with some of the more strange-looking species. In
the adjoining parish of East Horsley was a hilly piece
of ground known as the "Sheep Leas," as far as I
can remember the name. I am not sure of the ortho-
graphy of the word, — I give the name as it sounded to
me. This was a favourite place for a holiday of the
pic-nic order, and our people often resorted to it in
clays of yore. Many a pleasant day's botanizing I
have done there. It was there I made aqcuaintance
with the Aceras anthropophora and the Ophrys
nntcifera. The Ophrys apifera I found here most plenti-
fully distributed, in fact, almost carpeting the ground.
This odd-looking Orchis I also found in great abun-
dance in a " rough field " near the Fox, on Ranmoor
Common. I also remember a few being found in
Ockham Park one season. As to the 0. mucifera I
think it was under the beech-trees on the Sheep Lea>
that I found it. In the same neighbourhood I found
the Ophrys aranifera, and the Orchis hircina. I
think it was in the Sheepwash meadow already men-
tioned that I also found the Orchis' conopsca. — y. Mills

Colias Edusa. — Can any of your readers of
Science-Gossip give me a reason for calling the
clouded yellow butterfly " Colias Edusa "? " Colias "
meaning a kind of tunny-fish, and "Edusa" the
goddess who presides over the nourishment of child-
ren. — Ha z 'ila nd.

HARDWICKE'S SCIENCE -GOSSIP.
GEOLOGY,
The Glacial Phenomena of the Long
Island, or Outer Hebrides. — A paper on this
subject has recently been read before the Geological
Society by James Geikie, LL.D. The author gave a
detailed account of the glacial phenomena of Harris
•and the other islands that form the southern portion
of the Outer Hebrides. Evidence was adduced to
show that Lewis has been glaciated from S.E. to
N.W., and the shelly boulder-clays and interglacial
shell-beds of that part of the Long Island were de-
scribed in detail. Harris, North Uist, Benbecula,
South Uist, Barra, and the other islands that go to
form the chain of the Long Island were successively
described under the headings of Physical Features,
Geological Structure, Glaciation, Till or Boulder-clay,
Erratics and perched blocks, Morainic debris and
Moraines, Freshwater Lakes and Sea-lochs. Numerous
bearings of stride, which abound, were given, and
these were held to prove that the whole Outer
Hebrides have been glaciated by ice that flowed out-
wards from the mainland of Scotland. The position
of abundant ?-oc/ies moutonnees points to the same con-
clusion, and this is still further supported by the
"travel" of the Till. That deposit is generally
absent or very sparingly present on the rock-faces
that look towards the mainland, but it is heaped up
in their rear, and spreads over the lower tracts that
slope gently towards the Atlantic. On the west side
of the islands not a few boulders occur in the Till,
which have been derived from the east ; and the same
is true of certain erratics lying loose at the surface of
the ground. The islands are well glaciated up to a
height of 1,600 feet above the sea ; and the line of
demarcation between the glaciated and non-glaciated
areas is extremely pronounced. Above 1,600 feet the
hills show rugged, splintered, jagged, and sometimes
serrated tops. The author regarded the Till or
boulder-clay as the morainic material that gathered
underneath the ice, and proof of this is given. Erratics
and perched blocks are very numerous, and most of
these, as well as much of the morainic debris, are
believed to have been dropped where we now find
them during the final melting of the ice-sheet. It was
shown, however, that certain erratics and perched
blocks and some well-marked moraines are due to
local glaciers, as are also some of the striations in a
few of the mountain valleys. The origin of the rock-
basins, which are now lakes, was discussed, and
attributed to the erosive action of ice. To the same
cause were assigned the rock-basins which occur in
certain of the sea-lochs. In concluding, the author
pointed out that we may now arrive at a true estimate
of the thickness attained by the ice-sheet in the north-
west of Scotland. If a line be drawn from the upper
limits of the glaciations in Ross-shire (3,000 feet) to a
height of i,6co feet in the Long Island, we have an
incline of only 1 in 210 for the upper surface of the
ice-sheet ; and of course we are able to say what
thickness the ice reached in the Minch. Between
the mainland and the Outer Hebrides it was as much
as 3,800 feet. No boulders derived from Skye or the
mainland occur in the Till of the Outer Hebrides,
and this was explained by the deflection of the lower
portion of the ice-sheet against the steep wall of rock
that faces the Minch. The underpart of the ice that
flowed across the Minch would be deflected to right
and left against the inner margin of the Long Island ;
and the deep rock-basins that exist all along that
margin are believed to have been scooped out by the
grinding action of the deflected ice. Towards the
north of Lewis, where the land shelves off gently into
the sea, the under strata of the ice-sheet were enabled
to creep up and over the district of Ness, and thus
gave rise to the lower shelly boulder-clay of that
neighbourhood, which contains boulders derived from
the mainland. The presence of the overlying inter-
glacial shell-beds proves a subsequent melting of the
ice-sheet, and a depression of the land for at least
200 feet. The overlying shelly boulder-clay shows
that the ice-sheet returned and overflowed Lewis,
scooping out the older drift-beds and commingling
them with its bottom moraine. The absence of
kames was commented upon, and shown to be in-
explicable on the assumption that such deposits are
of marine origin ; whilst if they be of torrential origin
their absence is only what might be expected from
the physical features of the islands. The only traces
of post-glacial submergence are met with at merely a
few feet above present high-water mark.
The Fossil Fungus. — Too much credit cannot
be given to Mr. Butterworth for his labours on fossil
plants, carried on for so many years under great diffi-
culties but with great perseverance, and with most
important results. Prof. Williamson has again and
again expressed his obligations to Mr. Butterworth ;
and the collections of the British Museum have several
valuable specimens prepared by Mr. Butterworth's
own hands, the importance of which I have testified
to on several occasions. No doubt Mr. Butterworth
observed the fossil fungus in his specimens before
they were sent to London, although Mr. Smith and
myself were ignorant of it. But the fungus had al-
ready been observed by myself, and shortly described
from specimens in the British Museum prepared by
Mr. Norman, and the interest of Mr. Butterworth's
specimens to me, when they were shown me by
Mr. Young, was that they confirmed the specimens
I already possessed, and added to my knowledge of
the fungus. The two Pahrozoic fungi which Mr.
Butterworth refers to could not include the Neozoic
parasite in the fern-stem from Heme Bay, as he sup-
poses. These two Palaeozoic fungi were — 1. The
curious mycelium masses found at Newcastle by Mr.
Atthey, and described and figured in his "Annals
and Magazine of Natural History"; and 2. The

parasite fungus in the stem of a Lepidodendron de-
scribed by myself without a name, and afterwards,
by the help of Mr. Butterworth's specimens, de-
scribed at greater length by Mr. Smith. — William
Carruthcrs.
The Tkrtiary Flora of America. — Thanks
to Dr. Hayden, we have received the seventh volume
of the Report of the United States Geological Survey,
containing Prof. Lesquereux's "Contributions to the
Fossil Flora of the Western Territories," Part II.
"The Tertiary Flora." It is a large and handsome
quarto volume of nearly 400 pages, and contains
65 magnificently-lithographed plates. In every-
thing, type, lithography, quality of paper, and even
binding, these publications shoot far ahead of our
own " Memoirs of the Geological Survey," whose
small type seems intended to deter people from
reading them — a plan which is considerably aided
by the extravagantly high prices charged for them I
Our geologists are not particularly fortunate in the
possession of large salaries, and the high price
charged for their memoirs almost places them be-
yond the reach of ordinary readers, and thus con-
demns the labours of some of our ablest scientific
men to an undeserved obscurity. Moreover, the
niggardly way in which the publications of our own
survey are doled out to the authors, and the plan
adopted of sending none out for review, must be a
mode of treatment keenly felt by the authors, who at
least ought to be publicly credited with the scientific
value that would be attached by all geologists to
their work. In this respect the United States Go-
vernment is the very opposite of our own. Their
splendidly got-up volumes are sent over to the scien-
tific journals of Europe without stint, and so the
American States geologists obtain a recognition
which the unaccountable stinginess of the British
Government denies to ours. Prof. Lesquereux's
volume is the best we have seen of the series, and it
will surely take its place as a most valuable contri-
bution to Fossil Botany.
Ancient Vegetation. — The notice on this sub-
ject in last month's " Gossip " on American Silurian
plants is not quite correct, as plants have been known
long since in the " Glengariff " or " Dingle beds " of
Ireland. These rocks were taken by Jukes out of the
Silurians, and put provisionally in the "Old Red
Sandstone," on account of the plants found in them.
The "Dingle beds," however, pass downward into
typical Silurians, while they are capped uncon-
formably by the " Old Red Sandstone."— G. H. K.
NOTES AND QUERIES,
Starlings and Sparrows' Eggs. — Having
occasion to enter the roof of our house, I came across
the nest of a house-sparrow, and on looking into it
found that it contained three young ones just hatched,
one egg that was rotten, and to my great surprise a
starling's egg. This making me rather curious, I pro-
longed my search, and about three yards from the
nest occupied by the sparrows I discovered a starling's
nest containing five or six fully-fledged young ones.
I must not forget to state that the starling's egg
found in the sparrow's nest had apparently only been
sat upon but a few days. Will any of your readers
kindly state if such an occurrence is rare ? — C. If.
Sharp.
The Grey "Lag." — Can anyone give the mean-
ing of the word "Lag," as applied to the goose?
The proper grey wild-goose, as recognized by natu-
ralists, is popularly called the "grey lag," and the
universal summons to a flock of geese, in part of
Gloucestershire, is — "Come lag, Come lag, Come
lag." Now, whence "Lag"?— G. L.
Visits of the Cuckoo. — Does the Cuckoo, like
the Swallow, revisit the same place yearly? I feel
interested to know, for this reason. Last year I noticed
many times one of the same colour as the Kestrel,
quite red ; unfortunately I was not able to secure it
for my collection of birds. This year again I have
also seen the same bird or one very much like it, and
from this circumstance I am inclined to think that
the bird does return to the same place ; but whether
I am right or not I cannot say. At the same time,
will you be good enough to describe for me the
Cuckoo's egg. I have the Rev. F. O. Morris's
" British Birds," but the Cuckoo's egg is not described
there, I mean the colour of it. I procured a little
while back a very peculiar skylark, of a fine cinna-
mon colour. I have it stuffed in my collection. —
\Vm. Bennett.
The Swift's Appearance. — The fact of the
Swift appearing on May 1st is not a very unusual
occurrence. I live to the north of your correspondent,
I should therefore see it a little later ; yet I find, on
referring to my notes, that I saw numbers on April 30.
Stragglers put in an appearance about the 28th,
which is about the average date for this city. —
J. B. P., Herefoid.
Varieties of Camberwell Beauty. — In reply
to Mr. Morse's inquiry, I can most certainly say that
he is misinformed. I have seen numbers of specimens
of European V. Anliofa, and several British ones ;
there is a distinct difference in the shade of the border :
in the former it is pale yellow, in the latter a pearly
white or pale cream-colour. American examples
vary again ; the ground is the same or a little deeper,
but more dappled with black specks than the Euro-
pean specimens ; they are also much larger. I have
one that measures rather more that 3§ inches. —

How to Destroy Ants. — In reply to Mr. George
Pearce's question, as regards the most successful
mode of destroying ants, he will find Keating's
insect powder good, as it will at once kill them, and
if scattered about the rooms and furniture infested
by them, will effectually drive the ants away. — E.
Edwards.
Colours of Dried Primroses.— Can any of
your readers kindly inform me how it is that the
beautiful colour of the Primula vulgaris and clatior
should, when destroyed, change to a bright green,
leaving only the centre of the corolla (and that a
small portion), together with the stamens, the original
primrose-colour? The leaves turn brown. Is theie
any method of preserving this lovely flower, so as
to retain the primrose colour of the petals ? — E.
Edwards.

HARD Wl CKE'S SCIENCE - G OS SI P.
Dittany. — There is a foreign species of Marjoram
called " the Dittany of Crete," much used in medi-
cine, and known as Origanum Dictamtius, genus
Labiate?, and the "Bastard Dittany," Dicta minis
Fraxinella, one of a small order of Rutacea found in
Southern Europe and Asia Minor, and also the Cunila
mariana, called Dittany, likewise belonging to the
genus of Labiates. This is all I am able to find in
my botanical books concerning Dittany, and I have
much pleasure in forwarding it. — Helen Watney.
Mandrake. — Mandragora is the name applied to
a genus of Solanacece or Atropaceee, natives of South-
ern Europe and the East. Mandrakes have poison-
ous properties, and are somewhat like in their effects
to belladonna. The roots of the Bryony are often
trained round a mould, and then sold as Mandrakes.
Linnaeus considered the red-berried Bryony a variety
of the Bryonia alba, or White Bryony, which is a
Central European species possessing like properties
to the English species. --Helen Watney.
Robins' Eggs. — I found myself some years ago a
robin's nest, containing five white eggs, of a larger
size than any eggs of a robin that I have ever seen,
more the size of a cuckoo's egg. The other day I was
asked to name an egg, which from the nest I had no
hesitation in setting down as a robin's, too ; this nest
also had contained five eggs. As both these nests
contained the full complement of eggs, all of the
same size and colour, they must have been an abnor-
mal production from the birds. If there had been a
single egg, I should have concluded it to be a while
cuckoo's. Is this an unusual variety ? I have, you see,
come across two such instances myself; others may
have done the same. — C. A. Haden.
The House-Martin and House-Sparrow.—
At the commencement of the past week two martins
began to build under the eaves of my house. Being
a great admirer of them I was pleased, and hoped
nothing would hinder the completion of the nest.
It was not long, however, before I noticed two
sparrows taking more interest than I liked, and after
five or six days, when the nest wanted but little to
finish it, they drove away the rightful owners, and
took possession. I could not remain neutral ; so
with small pebbles I tried at intervals for two hours to
drive away the sparrows. This proved effective only
for the moment ; so I thought of another expedient.
Taking my trout-rod, I tied a piece of string to the
end and placed it within a foot of the nest. I never
saw more of the sparrows, but in less than an hour
the martins recognized the altered state of things, and
soon completed the nest. — H. G., Horbling Lodge.
Birds Singing at Midnight. — In Science-
Gossip for April i of this year there is an account of
"Birds Singing at Midnight," by Mr. R. Standen.
Goosnargh, "Lancashire, in which he states that he
heard the various songsters on the night of Saturday,
15th February. As I am rather anxious to fix the
exact date of the occurrence, I should be greatly
obliged by your informing me whether Friday, the
15th February, or Saturday, the 16th, is meant ;
either the day or date being evidently a misprint.— X.
Position of the Basque Flower. — Mr. Barrett
asks in the June number of SCIENCE-GOSSIP whether
the finding of Anemone Pulsatilla at a certain eleva-
tion "is a universal fact, or only a partial one"?
from my own experience I should say the latter.
I have found it in both situations ; but if I remember
rightly, in greater abundance in some of the chalk
ridges of the North Downs than in the lower-lying
country around. I have found it growing in the
corner of a hay meadow, the land being quite flat, in
the parish of Ockham, .Surrey, in close proximity to
some woodlands. I have also found it growing some
two or three miles off, in the adjoining parish of East
Horsley, on a piece of rising ground, or hilly pasture,
and called the "Sheep Leas." — J. Mills Higgins.
Soi.anum Dulcamara. — In reference to the
notes lately given about this plant, I forward the fol-
lowing facts. In 1869 one of my pupils partook
rather freely of the berries while he was searching
one evening for "haws." On reaching home he
became sick, and for several hours he was in a wild
and violent delirium, requiring to be forcibly held
down. This happened, too, after the stomach had
been emptied of its contents, the poison having had
time to extend itself into the system. The physician
who attended him at his house told me that the pupils
of the eyes were much dilated, and the symptoms
closely resembled those resulting from taking the
berries of Atropa Belladoima ; in fact, he concluded
that these were the berries the boy had eaten. Ice
in large quantities was applied to the head, and the
patient soon recovered. I copy this from notes which
I made at the time. It could not be ascertained how
man)* berries had been eaten. — Henry Ulyett, Folke~
stone.
Queries as to Flowers. — To what flowers do
the following lines allude ?
" One blossom, 'mid its leafy shade,
The virgin's purity portrayed ;
And one, with cup all crimson dyed,
Spoke of a Saviour crucified."
Holy Flowers, M. Howitt.
" So have I seen some tender flower,
Priz'd above all the vernal bower,
Shelter'd beneath the coolest shade,
Embosom'd in the greenest glade,
So frail a gem, it scarce may bear
The playful touch of evening air ;
When hardier giown, we love it less,
And trust it from our sight, not needing our caress."
Kedle.

Hop-gardens. — I am living in the midst of hop-
gardens. Can any of your readers kindly tell me if
there are any curiosities of vegetable or insect life to
be gathered during the season ? — A. C. Smith,
Crowbo7'o\
Lob-worms. — In reference to this subject by
Professor Paley, in Science-gossip for last month,
permit me to say that the materials found at the
entrance of their holes had adhered accidentally to
their slime, and were rubbed off on entering. Leaves
with stalks forward they do not carry, with the thin
end forward they do, and frequently pass into the hole.
Lob-worms clear away the things they have brought
home, because it is not convenient for them to adhere
again when they go out on visits of ceremony. In
clean-swept lawns these encumbrances are not met
with, and the entrance to the holes is not obstructed.
Crass and leaves may be eaten by these worms, but I
do not think they are taken to the hole, and then left
at the entrance for breakfast. Fifty years ago and
more I used to handle these creatures as Isaac Walton
did— tenderly.— //. P. M.
Blackbirds' Nest. — A pair of blackbirds have
built a nest just six" feet from the ground in a honey-
suckle climbing up a verandah outside our drawing-
room window, and close to a door which is in constant
use for going in and out of the garden. They have
now hatched their young ones in spite of all the dis-
turbance arising from curious eyes watching them,

and from three little terriers constantly playing and
barking immediately under the nest. — M. T. Palmer.
Batrachospermum, &c. — I cannot say whether
I shall be giving any or new interesting information
when I inform your readers that recently the Misses
Willis brought some fine examples of the lovely fresh-
water alga, Batrochospermum monilifornu from the
stream at Ewell. And that Mr. Morse, of the original
Epsom nurseries, discovered in the same parish, a
habitat for Cystopterts fragilis. — John E. Daniels,
Epsom.
Malformation in a Sheep. — I saw lately in
London a handsome well-grown wether sheep two
years old, with five legs, the extra one being apparently
anchylozed to the right scapula. The shank-bone
was full-sized, but instead of one set of the other feet
bones there were two, the four hoofs being prolonged
into claws. I have often met with monstrosities, but
not often so full-grown. — A. Bell.
Double Lilac— In a garden at Southend I have
observed a lilac-tree covered with double flowers.
The owner told me that five or six years ago this
peculiarity was first remarked on one or two branches
only. The quantity gradually increased, and now
the whole tree is nearly covered with double blossoms.
There are other lilac-trees in the garden which have
never shown any disposition to become double. Is
this an uncommon circumstance ? I have never met
with it before. — E. Fisher.
Superstitious Dislike to the Wren. — In
February's Science-Gossip, Mr. H. Allingham, in
an interesting note, speaks of the bitter dislike which
the country folk in some districts entertain to the
Wren. I have occasionally met with instances of this
superstition myself, but have always been unable to
trace the reason for such an aversion. Mr. Allingham
says the Wren has been designated the "devil's bird."
Has he heard the old couplet which says —
"The robin and the wren
Are God's cock and hen ? "
Apropos of this bird, I may mention that on Satur-
day, the 1 2th January, a newly-built wren's nest,
containing five eggs, was discovered at Galley Hill,
near Gravesend. — G. O. Howell, Shooter's Hill.
Double-blossomed Horse-chestnut. — In the
New London-road, Chelmsford, during May, a horse-
chestnut tree in the garden belonging to Weston Villa
was in full bloom. The flowers were apparently all
the subjects of multiplication, for in a panicle, which
I took the liberty to pluck, I found twenty-four petals,
and twenty stamens in one flower, and from the
general appearance of the flowers on the tree they
seemed more or less like it. The tree is well-grown
and vigorous, equalling in height the villa near which
it stands ; but is by no means old, so that it may be a
study for botanists during many years to come. —
John Gibbs.
Ranunculus repens. — In Cheshire the curious
or strange name of DeviPs-claw is applied to this
species, but in "Flora Vectensis" it is stated the
term is used to an allied species, the R. arvensis.
The Natterjack Toad (p. 142).— This reptile
emits a rather strong sulphurous scent when
frightened ; but only extremely fastidious persons
could consider it "a most intolerable odour." The
locality nearest to London in which I have found the
animal is Barnes Common, where it was very abundant
seven or eight years ago. It is also to be. found on
Coombe Warren, between Wimbledon Common and
Kingston.— IV. R. Tale, Blandford, Dorset.
Cheap Aquaria.— For the benefit of "W. D. B.,"
who asks for a way of constructing a cheap aquarium,
I will describe the primitive one I have in use. It is
simply a "carboy," such as can be procured at any
chemical works for a small amount of money. To
convert it into an aquarium lay a ring about ten
] inches in diameter on top of it for a guide, and run a
glazier's diamond around, then use a hot wire, and you
have a clean cut edge, which you can set off a little
by binding with tinfoil or something of a similar
■ nature. _ I don't know the exact capacity of mine,
but believe it approximates something near fifteen
gallons. For keeping in stock objects for the micro-
scope, such as entomostraca, infusoria, &c, I prefer
a small globe holding not more than two or three
pints.— H. F. Atwood, Chieago, U.S.
NOTICES TO CORRESPONDENTS,
To Correspondents and Exchangers. — As we now
publish Science-Gossip a week earlier than heretofore, we
cannot possibly insert in the following number any communi-
cations which reach us later than the oth of the previous
month.
V. G.— The insect, of which you sent us a sketch, is Lioellula
deprcssa.
E. E. Evans (Brimscombe).— Hewitson, in his " Eggs of

coloured tint at the smaller end.
T. Spencer Smithson.— Your letter inquiring the name of
a diatom did not contain any specimens when it reached us.
R. J. S.— The plants are not "Rushes," but " Cotton-
sedges " or "Cotton-grasses" {Eriophorum potystachynnr)
common in all marshes. Its economical employment has been
frequently attempted, but hitherto, we believe, without suc-
cess.
W. C. Penny (Frome). — The figure of Nynrphon gracile, m
the last number of Science-Gossip, is ten times the size of the

ANOTHER WAY OF MAKING PLASTER CASTS
OF FISHES, &.C
By J. H. LAMPREY, Editor of "Industrial Art."
M
1!
illi§il
I
^vSftfi^+r
AVING made many hun-
dreds of casts of sea and
fresh-water fishes, and
having tested every method
I have seen employed, I
have come to the con-
clusion that the simplest
and most effectual plan
is the following : — Place
the fish on a board, pin
out its fins and tail neatly
with ordinary pins, pass some brown paper or
tow inside the mouth, in order to raise the
eye if sunken from any cause, or to force asunder
the lines of the mouth and operculum, which
become contracted after death ; place some putty
under the dorsal fin, and then trim away all that
extends beyond its outline. The fish is now ready to
mould from. Next, take a long strip of thin sheet zinc,
about two or three inches deep, and place it in the
form of a wall all round the fish, and about one inch
from it, at every point ; partly split asunder a fire-
wood stick, and with it clip the free ends of the zinc
wall, drive in a twelvepenny nail at each end to keep
this wall steady. Bear in mind that both the pin
points and the nails need only sticking in the wood
in the most temporary way. Now take some plaster
of Paris in a cup, and, after mixing it as thin as cream,
smear the inside of the zinc along its edge where it
comes in contact with the board, and pour some down
the place of junction near the clip. In a few minutes
this extemporized dish is water-tight ; now nearly fill
it with the cleanest water procurable, and sprinkle
rapidly from a ladle some common or second-rate
plaster of Paris, coloured with a little washing-blue,
over the fish until it is just covered with plaster ; now
lay four pieces of strong cord across the fish, leaving
the .ends over the sides of the zinc receptacle ; having
arranged these cords so that they just touch the
plaster, without any loss of time continue to pour in
the dry plaster until the vessel is full, or there is at
No. 164.
least one inch of plaster over the highest part of the
fish, then remove the cords by lifting each end at
once ; as soon as the plaster is set, break away the
zinc band, and strike the board sharply with a hammer
until the plaster becomes detached ; if it sticks
closely, pour a pail of water over the plaster, and it
will at once give way. Turning over the mould we
have the fish buried in the case, or mould of plaster,
with only a very small portion of the underside of the
fish exposed where it rested on the board. Proceed
to break away the thin coat of plaster which has
settled along the margin until only an inch of plaster,
or even less, remains from the fish outline ; remove
the putty from the under portion of the back fin, pull
out the padding from the mouth, and then lift up the
tail, draw the thin end of the fish slightly backwards
and upwards; be careful not to injure the surface, but
get out the jaws and raise out the back. Use no force
that would break the fine surface of the mould. If
need be, open the fish, and remove the intestines,
and so give more space for getting out the fish ; this
being successfully accomplished, dip the whole mould
in water, and then pour in a spoonful of naphtha,
which will cover the cast with its oily adhesion ; wash
it again with water, and place the mould in a vessel
of water ; pour in the plaster so that it will fill the
interior of the mould, but have ready some copper
bell-wire bent to fit the tail, back fin, and pectoral
fin, if raised at all. No care need be bestowed upon
the shapes of these wire supports so long as they are
flat and just roughly define the form of the tail and
back fin ; the plaster must be poured over the mould
in sufficient quantity to represent the board on which
the fish was resting. By casting under water there
are no air-bubbles, and the plaster is homogeneous.
After a few hours, which may be profitably spent in
cleaning up the work-table of all the filthy plaster,
the plaster-mould must be plunged into cold water,
and the table on which it i-ests must be struck with a
mallet. To cause the mould to separate from the cast,
take a chisel, and where the line is defined by the
1

plaster of the mould tinted with washing-blue and
the perfectly white plaster of a better description
used in the casting, insert the edge of a broad chisel,
and tap it gently with the mallet ; make several very
cautious attempts along the edge of the two plasters,
until there is an evident sign of a parting having taken
place ; now plunge the whole under water, or pour
some over the edge, and the shrinkage will give the
desired cleavage. If, in endeavouring to break open
the plaster, a portion of the cast is knocked away, it
can be replaced, the cords drawn up through the half
set plaster have served to cut it up, but if the fish is
round, and the plaster has much "under-cutting," it
will require much skill to break away the mould
without injury to the cast beneath. It will be well,
therefore, to commence operations with a flat fish,
whose head, mouth, and eyes are the only highly
developed portions ; the fins can be pinned out, after
the skin has been washed with great care, to remove
all the slime with which most fish are covered. The
body of the mould taken from a flat fish of course
will come away like a seal, the impression beneath
being devoid of undercutting, but the head of the fish
cast requires great care, as about it are portions of
great delicacy of structure which may break away,
Casts of fishes in plaster are only of value to the
student ; they are heavy, and liable to injury ; to be
worth having, fish-casts should be made in paper.
From the plaster moulds we have described these
paper casts are made by successive layers of clean
white paper, and paste made from rice flour, backed by
coarse paper, chips, and thick wood shavings, inter-
spersed in the work, or a bit of common wire netting
cut to fit the mould, if the fish to be represented is
large in size, as a salmon or pollack. The first layers
of white paper need being spread with extreme care,
and if edges do occur in these first layers, the paper
must be torn and not cut, as the joining cannot other-
wise be concealed. The plaster cast cannot be painted,
all the attempts to make plaster and colour agree having
hitherto failed, andwhere gilding is resorted to, the sharp-
ness of the cast is utterly ruined. The paper cast can
be painted in fine washes of water-colour, or gold and
silver. The varnish over water-colour does not.injure
the sharpness of the mould, and it is possible so to
imitate a fish, in this way, that the veiy keenest
angler may be deceived as to the material. l There
are some fishes which can be cast showing both sides,
as a gurnard, or a cat-fish. Suspended by a fine
line, these casts are capable of accurately representing
the originals, but there is one difficulty about plaster
casting, — it is, without exception, the dirtiest occupa-
tion upon which an amateur can engage himself.
The plaster (if not properly dealt with) will follow
the operator over the house, adhering to his boots
and clothes, and hands, to the great discontent of
servants and others, who object to the filthy traces
which are so difficult to remove from floors and
carpets.
IS THE BLACKNESS ON ST. PAUL'S
MERELY THE EFFECT OF SMOKE ?
By Professor Paley, M.A.
MANY years ago I took a great deal of pains
to investigate a question which to many,
perhaps, will appear both trifling and useless, but
Avhich really has an important bearing on the aspect
of our great public buildings. It is often said, that
Paris is not such a smoky city as London, because
the stone buildings are much whiter. The north side
of St. Paul's Cathedral must, from its extreme black-
ness (curiously relieved as it is by lines and patches
of light), have attracted the attention and excited
the regret of most observers. There are other
buildings, of course, built with the same kind of stone,
which are equally black ; there are even towns, such
as Bath, built entirely of a similar (oolite) stone,
where all the new houses are of a rich creamy colour,
but most of those built a hundred years ago are as
black as a piece of black cloth.
From investigations I made, and which I think
worth being recorded, in order that further inquiries
may be conducted with patient and scientific care, I
was led to believe that this blackness is due to a
hitherto unknown and undescribed species of lichen.
Two of its peculiarities are, that it only grows
upon some kinds of limestone, and it will not grow
where the rays of the sun fall directly upon the sur-
face.
I first noticed the latter fact in a wall of rusticated
Italian work at Cambridge. It faced due west, and
it overlooked the country for many miles, so that
smoke was not likely to have caused the blackness.
The whole wall in this part reminded me somewhat
of the lights and shades of a photograph. Those
surfaces were quite black on which the sun could not
fall, and those remained quite white on which the
rays were directly incident. I concluded that, at
least, sun-light was in some way concerned in the
appearance produced. But what reason can possibly
be alleged why a stone should contract less soot in
the light than in the dark ?
I proceeded to scrape off some of the black sur-
face, which I collected, in the form of black dust,
exactly like gunpowder. If, I argued, the blackness
is really soot, surely a washing in hot water with
soap or soda will bring me white lime-dust, or lime-
sediment. But no ! I might as well have tried to
"wash a blackamoor white." The gunpowder was
gunpowder still, as far as the look of it went.
Then I tried the microscope. The washed granules
were intensely black, somewhat amorphous in aj)-
pearance, and more or less angular. My power was
not very high, and my knowledge of such very
minute cellular structure was too small : I could not
say whether the object was organic or inorganic. I
was afterwards told that under a good microscope it

had been conclusively proved to be vegetable, i.e.
-a lichen.
I found by extended inquiry that the Portland,
the Bath, and the Barnacle (also lower oolite) stone
were all liable to the blackening in the course of
time. But the churches and buildings of sandstone,
in that most smoky of towns, Wolverhampton, were
not blackened at all. Evidently it was an effect
peculiar to limestone.
I observed further, that in fluted columns, window-
jambs, arches, &c, the blackness was always in pro-
portion to the absence of sun-rays, and that the stone
remained quite white where the sun shone full upon
it. If any one will walk round St. Paul's, and com-
pare the south with the north side, he will see the
difference. Let him also notice the lines left white
by the oblique rays of the summer sun on parts of
the north wall.
In Bath, you may see whole ranges of buildings,
like the Circus, so black on the sunless side, that in
many cases the walls have been painted with black
paint, as giving at least a more shiny and respectable
black than my mischievous little lichen, which has a
dingy, sooty, uncanny appearance.
In other parts you may see a wall on the north side
perfectly black, while the east wall of the same
building is perfectly white.
On the smoke-theory, this is inexplicable ; on
the light-theory, it is precisely what we might
expect.
For if this blackness is really, as I now fully
believe, due to the gradual growth of a lichen, we
may conclude that it dislikes surfaces warmed and
dried by the sun ; and it is also to be inferred that
the lime is a necessary part of its food. I examined a
curious lichen, that grew in circular patches on the
Barnack stone in Peterborough Cathedral, and I found
that it had the property of extracting quantities of
lime from the texture of the stone.
But its extremely slow growth, requiring a long
series of years before complete blackness results, its
very hard and stony texture, its amorphous form, and
its extremely low organization, — the lowest, perhaps,
that vegetable life can possibly possess, — render its
history a very interesting one.
The practical result of the inquiry would be, to
ascertain if Portland and Bath stone can be treated with
some chemical solution, such as sulphate of copper,
which would prevent the growth of the lichen, sup-
posing it really to be such. It would be a valuable
scientific discovery that a brush and a pail would
restore surfaces that no water-washing will keep
dean, and not only restore, but prevent from
future discoloration.
If it be true that the beautiful Caen stone used in
Paris does not become thus black, it must be due to
causes well deserving of investigation. One cannot
help hoping that some process of "pickling" build-
ing-stone may be discovered, which will tend to
make churches and mansions less like an undertaker's
hearse.
I have not given, in this brief paper, the substance
of nearly all the observations, experiments, and
reasonings, which led me to the result I have de-
scribed. But I think some grounds of probability
have been shown, enough to encourage those who are
competent to prosecute the inquiry.
It is still open to conjecture, that some chemical
change in the texture of the stone, — some oxidizing
process gradually effected by the air,— may be the
cause of the blackness. But the singular effect of
sun-light in preventing it is a fact beyond all question,
and one that must be borne in mind in forming any
conclusion on the subject.
A CHAPTER ON MICROSCOPIC FUNGI.
(Perisporicurei. )
By Greenwood Pim, M.A., F.L.S.
THIS is a small but very interesting group of leaf
parasitic fungi, and includes most of the forms
popularly known as Mildews. In their immature
condition three species of this order form the mildew
of the rose, vine, and hop, respectively. That the
vine mildew is a member of this group is to a certain
extent an assumption, as its perfect fruit has never
yet been discovered ; and it is only by its analogy
to, almost its identity with, the rose, pea, and hop
mildews that it is believed to be the conidiophorous
condition of an allied species.
All Perisporiacei consist at first of a woolly growth,
consisting of delicate threads of concatenate cells,
arising from a mycelium, which makes its way through
the parenchyma of the stems and leaves of the plant
on which it occurs. Under a low power of the micro-
scope a mildewed rose-leaf looks like a delicate forest
of crystalline vegetation. The threads break up very
easily into their component cells, each of which, on
meeting with a suitable nidus, immediately com-
mences a separate existence, and, as is well known to
rose-growers and others, spreads with a rapidity
almost marvellous. In this condition the various
species obtained the name of Oidium, and it is only
comparatively recently that the identity of the Oidium
with the fully-developed conceptacles of the mature
form has been demonstrated.
In the case of the vine mildew, only the oidium
or conidiophorous condition is known ; the cells of
these threads being known as conidia. In the other
species, towards autumn a kind of spherical capsules
are formed, each containing one or more sacs or asci,
which include 2, 4, 8 or more spores. These concept-
acles are usually furnished with curiously-formed ap-
pendages, threadlike, curved, hooked, horned, needle-
shaped, forked, &c. By these characters, as well as
he number of asci and spores, the species which were

formerly almost all included in the genus Erysiphe,
have been divided into the following genera : — Peri-
sporium, Lasiobotrys, Spharotheca, Phyllactinia, Unci-
nitla, Podosphcera, Microsphezria, Erysiphe, Chcrto-
mium, Ascotricha, Eurotium.
I will endeavour to describe the forms most usually
met with, and would refer any one who wishes for
fuller and more detailed information to Dr. Cooke's
" Rust, Smut, Mildew, and Mould," and to his
"Handbook of British Fungi," to the latter of which I
am indebted for the generic and specific descriptions.
PERlsrORlUM, Kunze. Perithecia (conceptacles)
subglobose, without manifest mycelium or append-
ages ; spores numerous. The three species described
are far from common, and appear to approach in
character the neighbouring order Sphariacei.

ing above, attached to radiating fibres ; secondary
perithecia ascigerous ; asci cylindrical. There is only
one species, which is parasitic on living leaves of
Lonicera — L. lonicercc, Kze., which, though not com-
mon, appears widely distributed. It differs from the
rest of the order in being subepidermal.
Spplerotheca, Lev. Perithecia globose, spring-
ing from an arachnoid mycelium, containing one
many-spored ascus. Sphrerotheca is distinguished
from Erysiphe by having a single many-spored ascus,
while the latter has several asci, each containing but
few spores. Appendages numerous, floccose.
S. pannosa, Lev., the Rose Mildew, occurs on
leaves, petioles, &c. of roses. The conidiophorous
condition is extremely common, while the perithecia,
which are very minute, occur but very rarely.
S. castagnei, Lev., which differs but little from
S. pannosa, is found on Hops, Meadow-sweet, &c.
Phyllactinia, Lev. Perithecia hemispherical,
depressed ; appendages needle-shaped, stiff, and
brittle.
P. guttata, Lev. Conceptacles large, easily distin-
guished by their straight acicular appendages. Occa-
sionally very abundant on Hazel, also on Ash, Elm,
Alder, Birch, Oak, Hornbeam, &c. (fig no).
Uncinula, Lev. Perithecia globose ; appendages
numerous, simple, or dichotomous, always hooked.
U. adunca, Lev. Perithecia scattered, small ;
appendages simple, hooked ; asci 8-12, containing
4 spores. On leaves of Willows, Poplars, Birch, &c.
Rather common (fig. in).
U. bicornis, Lev. Mycelium effuse ; perithecia
rather large ; appendages bifid, hooked ; asci 8,
Fig. in. Uncinula adunca.

containing 8 spores. Sycamore-leaves, — common,
(fig. 112).
U. Wallrothii, Lev. Perithecia minute; asci 12-16,
6 spores ; appendages very long, hooked, simple.
Distinguished from U. adunca by the greater length of
the appendages (fulcra).
Podosph^ra, Kunze. Mycelium arachnoid ;
perithecia globose, containing a single 8-spored
ascus ; appendages few, repeatedly dichotomous,
thickened at the extremity, hyaline.
P. Kunzci, Lev. Perithecia minute, scattered,
globose ; appendages 3 times the diameter of the
perithecium. On plum-leaves.
P. clandestina, Lev. Similar to P. Kunzei, but
appendages much shorter and more numerous. On

leaves of hawthorn, common ; the conidia stage very 1
abundant in spring.
Microsph^ria, Let'. Perithecia globose, with
many asci ; appendages dichotomous.
M. Hedzuigii, Lev. Hypophyllous ; conceptacles
minute ; appendages few, scarcely longer than the
perithecia ; asci 4, containing 4 spores. On mealy

A word in conclusion as to mounting these fungi
for the cabinet. They seem to be best put up in
shallow varnish cells, filled with glycerine and water.
Deane's gelatine, so invaluable a medium for most
other vegetable preparations, is too viscid, the appen-
dages enclosing a myriad of air-bubbles, which in
gelatine are almost impossible to get rid of. More-
over, without a cell the covering-glass presses too
closely and is apt to cause the perithecium to rupture
from pressure. The modus operandi is a simple one.
When the cell is ready, filled with dilute glycerine,
scrape the leaf on which the parasite grows with a
sharp knife, which will remove a good number of
perithecia ; push gently into the mounting fluid, and
finish as in any other wet mounting.
ON TANKS FOR THE BREEDING AND
MAINTENANCE OF MICROSCOPIC
ORGANISMS.
IN the May number of Science-Gossip a corre-
spondent seeks information on the subject of the
establishing and management of tanks or receptacles
for the preservation and development of microscopic
organisms. To the microscopist it is a matter of some
importance, and one of which there seems to be no
record of any valuable, reliable, or actual experience.
The subject is of deep interest, and possibly your corre-
spondent and readers generally may consider the few
following notes, founded on many years' experience,
worth attention, more especially as the mode of esta-
blishing a permanent tank, containing microscopic
plants and animals only, is not generally studied or
even understood, the popular idea being that a collec-
tion of organisms found in the water of a rich pond
turned into a glass vase will at once afford and possibly
maintain and develop objects of interest and curiosity
for immediate examination, when in fact a keeping
or breeding tank requires many months, sometimes
years, for the perfect development of its contents.
No one could hope to raise the most interesting
features (to a microscopist) of a garden in a few days.
Time and the seasons are required to develop the
mosses, lichens, fungi, and obscure growths to be
found on good rockwork : the same prolonged causes
developing life, apply (perhaps in a lesser degree)
to the microscopist's breeding-tank ; it is a question of
patience. As a notable instance, the statoblasts of the
most beautiful of fresh-water polyzoa (Lophopus) are
frequently found in early autumn in the muddy sedi-
ments of ponds, rich in microscopic life. This
sediment, transferred to a well-ordered perfectly-
balanced tank, will produce the young polyps freely in
the spring, and there are numerous instances of a
similar character where time is a factor in the appear*
ance of microscopic life in captivity.
In the practical management of these tanks two
points are of essential importance : first, size, and, as
regards light, position ; secondly, the internal arrange-
ments, and the character, requirements, selection, and
management of the occupants, both vegetable and
animal, so as to ensure development and repro-
duction.
The shape and place of occupation of the receptacle
claim the first attention, and are of great importance.
It is true that ordinary glass jars or vases of various
sizes ai-e continually used with more or less success in
preserving living objects, but they utterly fail as
breeding or developing places : their circular forms
impede observation ; again, their portability causes
them to be frequently shifted into different aspects,
which is fatal to steady development. They are too
often placed in positions overwhelmed with light,
when they rapidly become choked with filamentous
algae, destructive to the preservation of the higher
microscopic forms. The proper adjustment of light
seems to be the touchstone of success in the cultivation
of organisms, both animal and vegetable. The
vitality of some water-plants, under what would seem
the most unfavourable, but, as it turns out, the most
favourable circumstances, is very singular ; the merest
fragment of Nitella will live for months in a wine-
glass of water, or even in a small test-tube, if kept in
a cool and rather dark place, but abnormally excited
by exposure to sun, light, and heat, it soon fades and
collapses. This is a lesson of importance, as un-
doubtedly the same influences affect minute animals.
The tanks for the purpose in question should not
be too large ; a convenient proportion, and meeting
all contingencies, is a vessel made of narrow iron
frame-work, glass sides and ends, with slate bottom,
measuring fourteen inches wide, fourteen deep, and
twenty-eight inches in length. Two or more of these
tanks are necessaiy : two are indispensable, as there
is a marked difference in the character of the occu-
pants of a tank facing a wall with only side light (and
no sun) and another facing a window (north aspect)
with occasional rays of setting sun. Besides these
permanent and larger receptacles, sauare glass vases
or vessels, such as are sometimes used for galvanic
batter}- cells, of the capacity of three pints, are very
valuable to contain objects dipped from the larger
tanks for special observation on the study table.
The permanent tanks should be placed in position
and never again moved. A good aspect is north-
east, fronting a window catching an hour's early
morning sunlight, but a better is against the wall of
a room or hall with a full side-light, and no sun;
the difference between the life contained in tanks
placed in such positions is strikingly apparent. Of
the internal arrangements anything approaching the
idea to make it "pretty" should be studiously

i75
avoided : nothing should be included but with the
object of use — the more useful the more beautiful it
will be ; two pieces of goodly-sized stone or irregu-
larly shaped brick should be placed nearly touching
the front glass ; these stones soon become covered
with organisms, and may be so adjusted as to be
within range of an ordinary magnifying lens. Two
or three plants (not more) of vallisneria, or chara,
are to be planted in one corner in well- washed gravel,
banked up with one of the pieces of stone ; the other
part of the floor of the tank should be left bare, to
facilitate the picking up, free of sand or gravel, of
anything that may appear. If a pond be accessible,
three parts of the tank are filled with water from it ; if
it be cloudy or even muddy the result may be more
favourable. After being left in repose for at least a
week, the character of the contents (if the pond be
fairly productive) will be seen ; the water will be
clear and probably reveal a variety of common objects,
such as larva; of insects, entomostraca, planaria, and
hydra; ; in a week or more vegetable growth will
appear, covering every portion of the interior. The
tank is now in a condition to be inoculated with
whatever choice objects can be obtained, the result
of special and favourable gatherings, and this should
be repeated frequently ; the front glass must be occa-
sionally cleaned with a sponge tied to the end of a
cane, but on no account be tempted to touch the
sides or back : the water will soon become as clear as
crystal, however muddy it may have been when first
introduced. The pieces of stone will show signs of
vegetable growths, with patches of such forms of in-
fusoria as vorticella; and stentors. The waste from
evaporation must be supplied by additions of pond
water (the richer the better), and such a tank will be,
in a month or two (not before), a marvel of micro-
scopic beauty and interest. The untouched back
glass will be covered with a dense mantle of dark-
green velvety vegetation, in the midst of which will
be discovered groups and patches of the fixed
infusoria, and it is essentially the habitat of the
polyzoa; hydra?, and the rarer rotifera philodina,
even melicerta and^stephanoceros, may be found under
such circumstances, to say nothing of the countless
tribes of free infusoria, ever ready for observation in
all their various phases of existence, and such con-
ditions will preserve and increase them indefinitely.
Enemies to eliminate are larva; of insects (but these
soon disappear naturally), the fluviatile arachiada;,
and the larger molluscs; the latter in browsing through
the vegetation on the glass are apt to destroy perhaps
a favourite group of stentors. Other enemies are the
floating filamentous alga; ; they should be removed,
but if the tank be well watched as regards light no
trouble in this respect may ensue. Nothing ought
to he planted in the middle, as it is of importance the
back glass should be clearly seen, and much may be
lost if anything impedes this view. It needs hardly
be said that the water must never be changed.
Tanks so established will greatly improve by time,
even when it extends to years. It is worthy of note,
as a matter of practical observation, that a great
excess of animal life (of a certain character) much
conduces to the development and well-being of
microscopic life. In a tank measuring fourteen
inches deep by fourteen wide and twenty-eight inches
long, five full-grown Mexican axolotls (nearly as
large as water-rats) have existed and thriven for
more than four years. In every part of this tank there
are swarms of Crustacea, infusoria, and rotifera, and
the back glass facing a wall is covered with the velvet-
like growth, shading off into patches of pale browns
and purples, imbedded in which are considerable
masses of living animal objects. It would seem as
if the rejectamenta of these axolotls (they are fed
once a week with strips of raw beef) is conducive
to the development of life. In large ordinary tanks
with growing plants of vallisneria, and not devoted
to the special object of these notes, it is desirable to
have a piece of floating wood ; it will in a few weeks
or months form the nidus or habitat of many strange
organisms. Vegetable forms requiring running or
moving water, as desmids, vol vox, &c, cannot be
reared or even kept in captivity. Much might be
said of collecting to supply tanks with objects did
space admit, but hydra; and countless forms may be
procured in abundance by the very simple process of
bringing in a handkerchief-full of duckweed, washing
it thoroughly in a pan, rejecting the weed, and
pouring the resulting water into the tanks.

HOW TO USE THE MICROMETER.
By F. Kitton, Hon. F.R.M.S.
ALL interested in microscopic studies have been
more or less inconvenienced by the frequent
absence of a scale of measurement attached to the
figures ; this is a great blemish in that otherwise
valuable work, " The Microscope," by Dr. Carpenter.
This in many cases was no doubt unavoidable, no
scale having been given with the original figures. As
the measurement of microscopic objects is by no means
difficult, eveiy one using the microscope should make
it a rule to ascertain the dimensions of the objects
he is examining. The only additional apparatus
required is some form of camera lucida : personally I
prefer Wollaston's ; others give the preference to
Beale's neutral-tint camera lucida (the former
costs 21s., the latter 7s. 6d.), and a micrometer ruled
in txits a"d r^ls. The chief difficulty in using the
camera of Wollaston is bisecting the pupil of the
eye with the edge of the prism ; if this is not care-
fully attended to either the paper or the object be-
comes invisible : practice soon overcomes the diffi-
culty. In using either form of camera it is necessary
that the body of the microscope should be horizontal.
176
HARD Wl CKE 'S S C1ENCE - G OS SIP.
In using the camera lucida two things have to be
considered : the dista nee of the prism or the reflector
from the object, and its distance from the paper.
(In my own instrument the edge of the prism with B
ocular, and i-in. Ross objective, is exactly 12 inches
from the object ; this distance with the paper 10
inches from the edge of the prism gives a magnifica-
tion of 369 diameters.) As the length of the body
and the magnifying power of the objectives and
ocular are variable, it is best to construct a scale for
the purpo se of ascertaining in the first instance
the amplification employed ; the most convenient
is the following : Rule a line 10 inches in length, a,
(fig. 117), and from the centre of this rule another
from 300 to 500 diameters by using the A B and C
oculars, and adjusting the amplification by means
of the draw tube or the elevation of the microscope.
A memorandum may be kept of the ocular used, the
length of tube, &c, but I always measure off a "Ol
with micrometer, which should of course represent
I, 2, 3, 4, or 5 inches, according to the amplification
employed.
The eye-piece micrometer, in its simplest form, con-
sists of a disc of glass upon which a series of equi-
distant lines are engraved; this is placed on the
diaphragm in the ocular, the lines being magnified
by the eye-lens. The distance of these lines is not
important, but, whatever their distance, they must be

line, b, of the same length at right angles to it ; care-
fully divide these lines into inches and tenths, then
rule lines commencing at a to the point c parallel to
the vertical line a ; rule nine other lines 1 inch
apart : each of these divisions represents one hundred
diameters. The inner margins of the lines b c should
be divided into tenths, and we shall then have a
series of diameters increasing by tenths 100, 1 10,
120, &c. This space between the lines a and e
should be ruled as accurately as possible with lines
"i'o of an inch apart ; this will give measurement to
the •0001 of an inch. I always prefer using such
diameters as are easily divided, viz., 100, 200, 300,
400, &c. With my i objective I obtain a range of
made to coincide with the divisions on the stage
micrometer ; when this has been done the object is
placed on the stage, the number of divisions occupied
by it gives the diameter in parts of an inch or milli-
metre, according to the divisions of the stage microme-
ter. This method, although somewhat less trouble-
some than that just described, is not so accurate, and
if the object is somewhat opaque (e.g., Aidacodiscus
formosus), the divisions on the eye-piece micrometer
are very indistinct.
For very delicate measurements eye-piece microme-
ters with fine screw adjustments are used, but for
ordinary measurements the camera lucida and stage
micrometer will be found sufficiently accurate.

Microscopic dimensions in England and America
are usually given in parts of an inch ; Continental
observers now generally employ some division of
the millimetre, such as 'I, 'OI, "ooi ; the latter is
sometimes written thus : 1 /* (/* = 1 millieme) -ooi
of an English inch = 25 /* -399. An English inch
contains 25 mm. "3995- A millimetre may be
roughly estimated as being equal to ^ of an inch.
Ehrenberg, Kiitzing, and the earlier microscopic
observers used fractions of the Paris line, or the ■£?
of a Paris inch ; the latter equals 27 mm. "12 ; the
Paris line equals 2 mm. '255. Rees gives the Paris
line -088815 of an English inch ; the nearest vulgar
fraction to this is 2-23rds = 087 12 1, differing by less
than I -500th of an inch. Practically the French
inch is equal to iT'ff English inch.
The scale used by Ehrenberg was i-25th of a Paris
line, magnified 300 diameters equalling two Paris
inches in length.
NOTES ON THE RHODODENDRON.
(~\N Saturday, the 1st of June, on our visit to the
^~*f Rhododendrons, at Cobham Park, my atten-
tion was drawn to the form of the flower by a query
from one of the party as to how fertilization was
brought about, seeing that the stamens and style all
pointed upwards, and the style was greatly exserted
beyond stamens. I was thus led to pay particular
attention to the point ; and, I think, was enabled to
arrive at a just solution.
A very small amount of attention demonstrated
quite clearly that the plant is proterandrous, i.e., that
the stamens arrive at maturity before the stigma is
in a receptive condition ; and that, therefore, although
the flowers are bisexual, they are to all intents and
purposes unisexual, as the stamens of a given flower
cannot fertilize the ovary of the same flower. This
might be inferred from the size and showiness of the
flower, as such plants, it has been clearly shown, are
usually entomophilous, i.e., are fertilized through the
agency of insects. We were soon enlightened as to
the peculiar fitness of the upturned style and stamens
for the purpose of securing cross fertilization by the
agency of large honey-loving insects, such as the bee.
While examining a cluster of flowers a large bee or
bee-like insect was seen to enter a flower ; and,
alighting upon the stamens, to apply its long pro-
boscis to the upper part of corolla at a point about
half-way down the tube. An examination of other
flowers showed in every case at this part a large drop
of fluid matter resembling dew or rain, but which
proved, on tasting, to be honey.
The modus operandi of fertilization was now patent
enough. Large insects, such as the bee, are attracted
by the honey ; and, from its position within the tube
of the corolla on the upper side, and from the form
and position of the 7tp-curved stamens, are unable to
reach it without, in the male condition of the flower,
literally dusting the under-side of the thorax and
abdomen with pollen, and without, in the female
condition, where the style protrudes beyond the now
pollenless stamens, depositing a portion of their trea-
sure upon the expanded glutinous stigma. Thus, as
they flit from flower to flower, in search of honey
for their own benefit alone, do these insects unwit-
tingly carry on a work that is absolutely essential to
the continuance of the specific life of the Rhodo-
dendron.
We may thus in a general way see and admire the
mutual adaptation of insect and flower for each other's
good, but a closer examination of the flower will
reveal to us many small modifications in the form of
corolla, stamens, ovary, &c, which cannot fail to
increase our admiration.

First, with regard to the colour of
the corolla. This is of an almost uni-
form tint, varying in different plants,
from deep rose-colour to pale pink, or
even white. Within the tube, how-
ever, on the upper side a number of
yellow oblong splashes will be found
forming more or less distinct lines,
clearly converging upon the drop of d£i^"a?W
honey already alluded to. Sir J. Lub- of Stamen (mag.),

that certain lines or striae lead to their food, use them
as guides in their future excursions. Hence, doubtless,

the raison d'etre of these lines or splashes in the
Rhododendron.
Secondly, with regard to the form of the corolla.
This, as in all Ericaca?, is monopetalous. When
pulled off and examined, it is found to be curiously
folded and plaited, especially near the base of the
tube on the upper side. A cross section taken near
the base is fairly represented by fig. 122 (magnified).
It will be seen from the figure that the dorsal fold is
so deep and perfect as to form a tube or canal. This
channel gradually shallows out at the point where the
honey is always found. What is its use ? At first
sight it appears as though the honey were secreted by
the corolla itself at the point where found, but such is
not the case. On pulling off the corolla, the honey will
be seen oozing from the upper side of the base of the
ovary. The use, then, of this fold appears to be to
act as a tube for the passage of honey from the base
of the corolla to a point nearer its mouth where it is
more readily accessible to insects of a large size.
The honey, doubtless, passes up this tube by means
of capillary attraction.
The stamens are very peculiar, as will be seen from
fig. 120. The lower half is thickly covered with stiff
glandular hairs of very various forms and lengths.
Some of these forms are represented in fig. 121. One
use of these hairs is, perhaps, by firmly interlocking,
to strengthen the stamens, and enable them the better
to resist the pressure of insects alighting upon them ;
but the principal one, I should think, is by means of
their crowding and intertwining, to prevent smaller
insects, that would be incapable of carrying on the
work of fertilization, from penetrating to and carry-
ing off the honey, which is the incentive to the visit
of those larger insects that are capable of performing
the task. The bottom of the stamens, as shown in
fig. 120, is free from hairs, and rests in a groove in the
hypogynous disc that surrounds the base of the ovary.
This insertion in a groove and close application to
the ovary cannot fail to give additional stability and
strength to the stamens as a whole, while it most
effectually prevents any insect from arriving at the
source of the honey.
The imperfectly ten-celled ovary, with its surround-
ing secreting disc, is represented by fig. 119. The
upper two lobes only of this disc, which are larger
than the rest, appear to be concerned in secreting,
or, at all events, in pouring out the honey.
This paper is written, not as an exhaustive account
of the flower of the Rhododendron, but as an incen-
tive to further examination by others. As my oppor-
tunities of observation are small, I feel sure that
those more favourably situated may, by a little atten-
tion, show us many curious and highly-interesting
points that I have altogether overlooked ; and I, for
one, should be very glad to get a fuller and more
perfect account of this plant.

ACCLIMATIZATION OF PALMS.
By Staff-Surgeon R. Nelson, R.N.
PLANTS differ greatly from animals in the close-
ness of their adaptation to meteorological and
other conditions ; hence, on the one hand, while in
England, we can have parrots, monkeys, lions, tigers,
and other tropical and sub-tropical animals, live with
us during winter, and even the polar bear look as
pleased as a bear can look during our hot summer
months ; we lose, on the other hand, the enjoyment
of many beautiful wild flowers and magnificent forest
trees which enliven the scenery and greatly enhance
the pleasure of the traveller abroad.
Who that has travelled much does not remember
the pleasure, nay, the rapture which he felt as he
neared his first foreign port — say Madeira, for in-
stance— in beholding the luxuriant "feathery palm-
trees rise," as Heber sung when he linked them
together with other of our earthly conceptions of
"the better land." They are undoubtedly the first
objects which forcibly strike the wanderer, and enable
him to realize that his dear old home is far behind,
and that he is, indeed, in a distant land. There is
nothing so thoroughly foreign to the eye, and few
objects in nature more attractive. The long-tailed
Celestial, the almond-eyed "Jap," and the black-
skinned negro, have been long familiar in our streets,
but the palm stands out in broad relief as the first
novelty which attracts attention abroad.
Having lately spent some months in Shanghai, I
have been led to these remarks by observing, during
the present severe winter, how well the few palm-
trees planted there have withstood the rigour of the
climate, and was first forcibly struck with the subject
when, one bitterly cold morning, a friend called my
attention to the almost anomalous condition of nature,
that the palm-trees were covered with snow ; and
very pretty objects they were.
What genus or species of Palmacese they belong to
I cannot at present discover, but doubtless many
readers of Science-Gossip know which are the
hardiest of the order. That the specimens planted
along the Bund of Shanghai are as graceful as the
lofty cocoa-nut trees of Ceylon, or the Sago-palm of
Borneo I do not maintain ; but they are well worthy
of the attention of those interested in the acclimati-
zation of plants, for few things would add more to
the beauty of our parks, or better set off a landscape
than endogenous trees, of which our climate has, or
is supposed to have, deprived us.
Shanghai is situated on the Woosung river, about
twelve miles above its junction with the mighty
Yang-tze-Kiang ; the country around is perfectly flat,
and the soil alluvial. Although so far south as 31°
N. lat., 200 below the south of England, the winter
is rigorous, and altogether the climate bears a most
remarkable contrast to places in the western hemi-

M.R.I. A., &c.
THE metropolis of Ireland is most favourably
situated with regard to its position, its eastern
extremity being bounded by the sea, to the north-
east the peninsula of Howth forms the limit of
Dublin Bay in that direction, to the south that of
Kingstown and Dalkey ; south of Dublin the granite
range of mountains are a conspicuous feature in the
landscape.
Of the igneous rocks, granite, the most important,
is well displayed near Dublin, commencing about
three miles south, extending in a south-westerly
direction for a distance of twenty-nine miles to near
New Ross, in the county of Wexford, with an average
width of eight or ten miles, and a maximum, at one
part, of eighteen miles. It forms the Dublin moun-
tains, rising to an elevation of 1,763 feet from the
sea-level, above the Three Rock Mountain at Fairy
Castle. The lower hills, near the sea-coast, such as
that of Killiney, are 480 feet, and Dalkey 472 feet,
in height. The outline of this range shows a suc-
cession of gently-undulating and rounded eminences,
descending more rapidly towards the sea.
In the adjoining county of Wicklow the mountains
rise to a greater height ; Lugnaquillia, in the southern
part of the county, being the highest, is 3,040 feet
elevation, consisting of a mass of mica schist resting
on the granite ; all the loftiest parts of the adjacent
mountains are also composed of mica schist.
The granite may be seen along the coast from
Blackrock, south of Dublin, to Kingstown and
Dalkey ; from the latter place it has a superficial
breadth of about eight miles. From the quarries at
Dalkey Hill was obtained the stone used in the con-
struction of the harbour and piers at Kingstown,
about 6,000,000 tons being used in the formation
of the two breakwaters. A large quarry in the town
of Kingstown was also extensively worked for mate-
rial used in the construction of the harbour and
piers at Kingstown ; other quarries have been
opened on the eastern side of the Three Rock
Mountain for supplying stone for building purposes
and for flagging.
The Killiney and Dalkey granite is coarsely
crystalline, varying somewhat, however, in different
places. The Rev. Dr. Haughton, F.R.S., &c, has
fully described the Dublin and Wicklow granites in a
memoir of the Lower Palaeozoic and associated Igneous
rocks of the south-east of Ireland. ("Trans.
Royal Irish Acad.," vol. xxiii., 1859, pp. 564, &c.)
Veins of a closer and whiter texture, in which the
mica is scarcely or not at all perceptible, are fre-
quently found to traverse the granite of this district ;
it is called Enrite, and is evidently intrusive ; occa-
sionally it assumes larger dimensions than that of
mere veins. Black mica (Lepidomelane) is not
uncommon in this granite ; a remarkable plumose
variety of white mica (Margarodite) has been found
at Ballybrack. In the Dalkey quarries it is not
unusual to find perfectly-formed crystals of black
quartz in the joints ; fine crystals of Tourmaline
are also occasionally met with in the granite of
Dalkey, and the mineral called Killinite, from its
having been found in the granite of Killiney and also
at Dalkey.
Metamorphic Rocks. — Mica schist, or altered
Lower Silurian slates, these again blending into
unaltered Lower Silurians, flank the granite from a
point near Killiney to near New Ross, in the county
of Wexford, spreading out, as shown on the southern
boundary of sheet 121 of the Geological Survey maps
to a breadth of over four miles. The junction of the
Granite and Metamorphosed Slates is clearly observ-
able along the sea-shore under Killiney Hill, at
Roche's Hill, and to the west of Killiney Park ; in
the road and railway cuttings of the neighbourhood ;
as well as their metamorphism into mica schist, which
often contains crystals of chiastolite.
The manner in which the granite has been forced
into the slates, penetrating them in wedge-shaped
masses and veins, may be observed on the shore at
this place. From the Killiney Hills a fine view of
the Bay of Dublin, with Howth to the north and
Bray Head south, may be seen.
The Scalp, about two miles north of Enniskerry,
and about three miles south of Carrickmines station,
on the Dublin, Wicklow, and Wexford Railway, is a
picturesque pass, the granitic rocks showing great
erosion ; its junction with the mica schist may be
readily observed.

NOTES ON CELERY AND OTHER SMALL SALADS,
By H. G. GLASSPOOLE.
ELERY {Apium graveo-
Icns) belongs to the
Umbellifene order of
plants, and in its wild
form is found growing
in ditches and marshes
near the sea, in Europe
and in Britain, where it
is known under the
name of Smallage ; but
in this state it is wholly
unfit for food, having a peculiar coarse rank taste and
smell, being considered poisonous to man, and is not
even relished by animals. Cultivation, however, has
transformed this suspicious plant into one of the most
agreeable and wholesome of all our esculents. This
species of Apium appears to have been known to the
•ancients, for it was reckoned by them as one of the
greater aperient roots, and Pliny states that it hath
a peculiar virtue against the biting of venomous
spiders. There is no account from which we can
gather that the ancient Greeks and Romans were
-acquainted with the method of bleaching this plant,
and thus rendering it fit for food. By most of our
old herbalists, it is mentioned under the name of
Smallage, and only used by them as a medicinal
plant. Gerard tells us that the leaves of it boiled in
hog's-grease and made into the form of a poultice,
taketh away the pain of whitlows on the fingers, and
healeth them. Culpeper recommends that the juice
■of this plant, mixed with honey of roses and barley-
water, be used as a gargle by those who suffer with
sores and ulcers in the throat and mouth. Bartho-
lomseus Lorn, in his " Botanologia," (published in
1 7 14), mentions that the roots and seeds of Apium
were used medicinally in his day. This esculent
appears to have been cultivated for the table at the
early part of the seventeenth century, for John Ray,
the celebrated botanist of that period, says that, if
this plant is neglected, it will degenerate into its first
unpalatable state. We are indebted to the Italians
No. 165.
for the method of its cultivation, and also for its
name. Evelyn, in his " Acetaria " (published 1699),
says " Sellery was formerly a stranger with us,
and not very long since, in Italy itself." He tells
us that it is not a distinct species of Smallage,
or Macedonian parsley, though, by its frequent
transplanting, somewhat more hot and generous, and
sweeter-scented. We have, he says, " the best seeds
from Italy, whose tender leaves and blanched stalks
do well in our sallets, as likewise the slices of the
whitened stems, which being crisp and short, first
peeled and slit longwise, are eaten with vinegar, oil,
salt, and pepper. And for its high and grateful taste
is ever placed in the middle of the grand sallet, at
our great men's tables and Pnetors' feasts, as the grace
of the whole board." In our oldest seed-lists we find
that two varieties of celery were introduced from
Italy under the name of Red and White upright
Italian celery. It is stated in the " Monthly Maga-
zine and British Register," for July, 1797, that the
seed of a new sort of celery, from the island of
Samos, had been introduced into the county of Nor-
folk, which grew to the height of three feet, and
possessed other superior properties. Celery may be
grown to a very large size, for Loudon states that, in
1815, a plant was taken up at Longford, near Man-
chester, which weighed 9 lb. when washed, with
the root and leaves still attached to it, and measured
4 feet 6 inches in height. It was of the red sort,
perfectly solid, crisp, and firm, and remarkably well-
flavoured. There is a variety of this plant called
Celerica, or Turnip-rooted celery {Apium graveole its
napazeum) ; it is more hardy than the upright varieties :
of this the root is the only part used. It attains to a
considerable size, especially in Germany, where it is .
much esteemed, both prepared by itself and in con-
junction with other herbs as a salad. It rarely forms
an object of cultivation in English gardens. Sir
Joseph Banks and Dr. Solander found in considerable
quantities, on the coast of Terra del Fuego, wild
celery, which appears to be possessed of wholesome
K

qualities, as it was found a very useful ingredient in
the soups for seamen, because of its antiscorbutic
properties. Celery contains sugar, mucilage, starch,
and a substance resembling manna sugar, which acts
as a stimulant. A decoction made from the seed and
drunk as tea is often recommended in some diseases
by village herbalists. Celery is regarded as a lucky
plant by the modern Greeks, and is hung up in rooms,
placed on silkworm-frames, and given to children.
The common name appears to have been derived
from Italy, — sellari, under which it was introduced in
the old seed-lists into this countiy, but it is found in
old works, spelt in various ways ; thus, Sellery,
Celeri, and Celery.
The etymology of the botanical name, Apium,
appears uncertain. Some authors think it is derived
from the Celtic Apon, water, from the place where
the plant grows ; others state it is from Apis, a bee,
because these insects are fond of it. Celery has
quite supplanted our native Alexander's (Smyrnium
Olusatrum), which our forefathers used to eat as a
common salad.
Among other herbs which are sometimes to be
found in the salad-bowl, are the various Valerianella,
or Lamb's lettuce. The French call them Salade de
pretre, from their being eaten in Lent. Evelyn says
they certainly deserve a place among the penitential
herbs, for the stomach that has admitted them is apt
to cry peccavi. The leaves of Burnet (Poterium
sanguisorba), when bruised, have the smell of cucum-
ber : in former time this plant was in great repute. A
small low thistle {Picridium vulgare), is often used in
France and Italy, both as a salad and greens. Bon
Jardinier says it tastes a little like mutton. The
flower of the Judas-tree (Cercis siliquastrum) and
leaves of the Wood-sorrel {Oxalis acelosella), when
mixed with other herbs, give an agreeable acid flavour
to the salad.
Dr. Thomas K. Chambers, in the "Manual of Diet
in Health and Disease," says, " Salads ought to form
an important article of diet in every family. The
salad ought to be dressed by one of the daughters of
the house after she has dressed herself for dinner,
singing, with her clean cool fingers, sharp silver
knife, and wooden spoon —
" Weaving spiders, come not here :
Hence, you long-legged spinners, hence ;
Beetles black, approach not near ;
Worms nor snails, do no offence. "
The purity of the salad-bowl is also of great im-
portance. In the days of the Tudors the cooks were
accustomed to mix their salads in a silver saladier, or
some other vessel of metal which was affected by the
chemical action of the acids so composing the mix-
ture, and must have proved deleterious to those who
partook of it. Evelyn, the great reformer in the art
of salad-making in those days, says, the proper
material for the salad-bowl should be porcelain, or of
Holland delf-ware. We find in the writings of our
old poets and dramatists allusions to salads, as is
shown in the following conversation between Lafeu
and the Clown in " All's Well that Ends Well ":—
"Lafeu. 'Twas a good lady, 'twas a good lady;
we may pick a thousand salads, ere we light on such
another herb.
Clown. Indeed, sir, she was the sweet marjoram
of the salad, or rather herb of grace.
Lafeu. They are not salad herbs, you know, they
are nose herbs.
Clown. I am no great Nebuchadnezzar, sir ; I
have not much skill in grass."
The author of the " Book about the Table " states
that Poetry seized the dish to use it as an emblem of
vernal freshness and greenness.
Shakespeare's Cleopatra says —
" My salad days,
When I was green in judgment."
Our forefathers were accustomed to introduce the
salad into some of their wise and pithy sayings, for
among our English proverbs we find the following : —
"A fool can pick a sallet as well as a wise man."
"He would live for aye, must eat sallet in May."
The following is a translation of a Spanish proverb r
" Four persons are wanted to make a good salad.
A spendthrift for oil, a miser for vinegar, a coun-
selor for salt, and a madman to stir all up."
Dr. Doran, in his "Table Traits," tells us of a
certain Frenchman who made his fortune by making
salads for the aristocracy of England. Chevalier
d'Albignac, one of the refugees which the great
Revolution had cast on our hospitable shores,
where he, like many of his unfortunate countrymen,
contrived to subsist on a small pittance allowed him
by the English Government, was one day dining with
an affluent friend in the coffee-room of a fashionable
hotel ; he took upon himself to make a salad, and
the way he handled and mixed the preparation at-
tracted the attention of a young nobleman who was-
dining with another party in the same room. The
nobleman approached the foreigner, and politely
entreated him to mix a salad, French fashion, for
his table. M. d'Albignac consented, and made such
a one that put the four gentlemen into a state of un-
controllable ecstasy. His complaisance and com-
municativeness to the young nobleman and his
friends had agreeable results, as they did not let the
poor Frenchman depart without slipping into his
hand a golden fee. A few days after M. d'Albignac
received a letter from a certain lord, politely request-
ing him to repair to his house in Grosvenor-square
for the purpose of mixing a salad for a dinner-party
he was about to give. The Chevalier obeyed the
summons, and after performing his mission returned
home, richer by ^"5 than when he went out. His
marvellous salads were soon the talk of the town.
The "gentleman salad-maker" was the hero of the
hour, and ladies of the highest fashion, we are told,
HARD WICKE'S S CIENCE ■ G O SSI P.
*95
were heard rapturously commending his " works " in
gilded salons, or avowing they could not live another
week without devouring one of them. The lucky
Frenchman was soon enabled to start his carriage,
and might be seen driving from house to house
during the dining hours of the aristocracy, attended
by a servant, who carried a mahogany case, which
contained the various ingredients for concocting his
salads, according to the taste of his employers. He
opened a shop, where he drove a lucrative trade in
sauces and other culinary dainties. Being a prudent
and saving man, he managed to realize some 80,000
francs, 60,000 of which he invested in government
securities, which stood just then at 5° per cent., and
with the other 20,000 he purchased a little estate at
Limousin, where he spent the rest of his days en-
joying his well-earned fortune.
I conclude by introducing a
Receipt for a Winter Salad, written many years ago, j
at Castle Howard, by the Rev. Sydney Smith : —
" Two large potatoes, passed through kitchen sieve,
Unwonted softness to the salad give ;
Of mordent mustard add a single spoon —
Distrust the condiment which bites so soon ;
But deem it not, thou man of herbs, a fault
To add a double quantity of salt.
Three times the spoon with oil of Lucca crown,
And once with vinegar procured from town.
True flavour needs it, and your poet begs
The powdered yellow of two well-boiled eggs.
Let onion atoms lurk within the bowl,
And, scarce suspected, animate the whole.
And lastly, on the flavoured compound toss
A magic tea-spoon of anchovy sauce.
Then though green turtle fails, though venison is tough,
And ham and turkey are not boiled enough,
Serenely full, the epicure may say,
' Fate cannot harm me — I have dined to-day.' "
A HOLIDAY ROUND DORKING.
LIKE most of those who are engaged during the
day with the bustle of City life, we were
anxiously looking forward to rest and quietude in the
country, where we could throw off for a while the
routine and formality of business, and enjoy that
sense of freedom which only the lover of nature can
appreciate.
The longed-for time came at last, and after the
usual amount of preparation we arrived at Cannon-
street station, and were soon spinning away from
dusty London into the more picturesque country.
The sun was shining brightly into the carriage, and
the atmosphere was anything but cool ; but we
were in excellent spirits, and such weather led us to
hope that we should spend a very happy holiday,
being particularly suitable for our chief pastime,
entomology. At length we arrived at Dorking sta-
tion, and everything around looked bright and
promising, as we got into the conveyance which was
to take ourselves and luggage to the town. We con-
tented ourselves for the remainder of the day with a
general survey of the town, which presents the
appearance of a thriving but quiet country place.
We were greatly delighted on waking next morning
to find that the weather promised to be a repetition
of the day before. The first thing for us to do, after
having enjoyed a good breakfast, was to settle in
what direction we should go, as we were very anxious
for the chase, and our nets and boxes were all in
readiness. Leaving Dorking at ten, and not for-
getting to fill our flasks with lime-juice, we took a
friend's recommendation, and started off in the
direction of Ranmer Common, distant about two
miles. Just past the railway-station, South-Eastern
Railway, we found a chalk-pit, and were not long
in discovering that some sport was to be obtained
therein. Getting over the railings a very bright-blue
butterfly was seen ; the gauze soon enveloped him,
and he turned out to be the Adonis, Clifden Blue.
He was sadly battered, as it was quite a month late
for him, so we gave him his freedom, and away he
went, no doubt happy to be released from our
clutches. No sooner had we done this than we
noticed a dull-looking little insect tripping sharply
along, and settling for a moment on the blue flowers
that grew in the chalk. This we soon found to be
Alsns, the Bedford Blue, and we were very pleased
to find them in great plenty and very nice condition.
After another parting look round the chalk-pit, and
having beaten a few blackthorn bushes unsuccessfully,
with the exception of taking one Jacoba, we went on
our way to the road which leads to Ranmer Common.
We had been told that parallel with the road was a
grassy path, adjoining a very pretty estate called the
Denbighs, and that we should very likely have some
sport if we went that way, and, moreover, avoid the
dust of the chalky road. Immediately we got into
this path we noticed the intense contrast which the
fresh foliage of the trees afforded from the dry chalk.
On our left was a thick plantation of pine and fir-
trees, and on our right a hawthorn hedge, separating
us from the road, whilst peeping out from the grassy
bank was an occasional patch of wild strawberry-
plants, some in bloom, and others loaded with the
pretty rosy-coloured fruit. This path soon widened into
almost a glade, with a wonderful variety of herbage :
blackthorn, whitethorn, juniper, clematis, privet,
honeysuckle, and almost every imaginable kind of
vegetation. The sun was now blazing forth, and we
were out of the shade which the pines afforded ;
moreover, insect life was swarming all around us.
The two common skippers, Lima and Sylva7ins, were
buzzing about in the utmost profusion ; the Meadow
Brown, Mctgeria, was lazily flitting from one flower
to the other, sometimes with that sombre quiet-looking
butterfly, Hypcranthus, the Wood Ringlet ; every-
thing seemed so quiet and happy, affording such a
contrast to the noisy city which we had only the day
before quitted. Soon we came to another plantation,
and then sport began in real earnest. What is that
flying round the top of the pines, and occasionally
descending to within reach of the net? We strained

our necks trying to capture one, and soon found it
such hot work that our coats were off and satchels
laid down, whilst F., who was not an entomologist,
was not sorry to take a rest by seating himself on
the stump of an old tree. Our nets had only got
short walking-stick handles, so our chance of success
seemed very small at first, more especially as there
was a hollow between the path on which we stood,
and the ground on which the plantation was situated ;
if we made an extra effort in our excitement to

secure our prize, we were thrown from the path
amongst the bushes below. But we were not thus to
be disheartened, so taking a pull at our flasks, and
wiping our perspiring faces, we again set to work.
This sort of thing continued for nearly an hour, in
which time we obtained about a dozen each of
Pittiaria, and discovered that it was nearly time to
return home, without reaching Ranmer after all.
On looking around from the elevated position
which we now occupied we were all struck with the
marvellous view which presented itself. The railway
lay in a valley, and on rising groun beyond stretched
the well-wooded district around Leith Hill and Cold
Harbour, and the contrast between the various kinds
of vegetation was wonderful ; towering above all was
Leith Hill itself, standing out boldly from the clear
blue sky, while on the right of the railway could be
seen the long ridge of hills in the direction of Guild-
ford. Streams meandered here and there, and the

sun shining on them made them sparkle like dia-
monds. We were indeed glad that we had come to
Dorking, for we had never seen a finer piece of
landscape before. Moreover, the intense heat, the
cloudless sky, and the buzzing of the bees, gave a
lazy look to everything around ; the cows in the

no means pleasing companions.
Common, and accordingly made arrangements to
have a late dinner. This time we took the road, on
the right hand side of which was a stone wall, with
a plantation above. Flying up and down this was

In the afternoon we went for a drive to Shiere, a
village about half-way between Dorking and Guild-
ford, which we enjoyed very much, after having had
a good tea, and partaken very freely of strawberries,
which the landlord had just gathered from his garden.
The next day we determined to reach Ranmer
Stellatarum, the Humming-bird Hawk-moth. It
j gave us a rare chase, with no success, so we made up
our minds we would hurry on towards the Common.
On arriving at the end of the road, and unfastening
1 the gate, we found ourselves on a large tract of wood-
' land and common, which seemed to invite us to more
i98
HARD Wl CAGE'S S CIENCE . G OSS IE.
closely examine it, which we accordingly did, and
set off down a long glade, which made us think it
should be called a wood rather than a common.
The trees were chiefly oak, with an undergrowth of
bramble, honeysuckle, and blackthorn, and on going
a little farther in, we came upon a magnificent group
of wild foxgloves, all in full bloom, and some of
them as much as seven feet high. What was that
large golden butterfly which just flew over our heads?
exclaimed J, It must be Papkia, and sure enough it
was, for no sooner had we spoken than back he
came, and settled on a bramble, right in front of us,
flapping his wings in the sunshine as if making fun
at us. For a moment we were speechless with plea-
sure and admiration, for this was the first time we had
seen any of the large Fritillaries on the wing. Then
quickly raising his net without letting the shadow
intervene, J. gave a swift stroke over, and the silver-
washed Fritillary was safely in his net. We did not
have to wait long before seeing several others as we
went farther down the glade ; they all flew very
swiftly, and appeared very fresh on the wing, it being
only the second week in July. After we had obtained
about half-a-dozen each, and having captured a few
Tliec. quercus flying round the oaks, together with
some Trilinearia, which we beat out of some beeches,
we resolved to try the old wall again, and return to
the Common next day. On our way back we man-
aged to capture three Stellatarum, and then we turned
into the grassy path before mentioned. In one of
the fields the grass was particularly high, and we
thought it not unlikely something might turn up in
it. We soon found that we were to be rewarded for
our trouble, for we obtained about twenty of that
delicate little geometer, A. oruata, and also dis-
covered^. Galathea in the neighbourhood. We espied
the first one, seated on a thistle-head, evidently
only just emerged from the chrysalis. This was a
very agreeable surprise, as we had neither of us taken
Galathea before. We took as many as we wanted,
and then lay down under the shade of a yew-tree,
and watched them bobbing up and down in the long
grass. Whilst dreamily passing the time in this way,
suddenly something whizzed by like a great bee, and
then back again, circling round the meadow in a very
giddy way ; then it seemed as if making straight for
me, so getting my net in readiness, with a swift
sweep, I secured it. What could it be ? It buzzed up
and down the net with great vehemence, and I was
very anxious to see it safely bottled in the cyanide.
When this was done we found that we had captured
B. rubi, the Fox-moth, and a very hot chase we had
for the other two we secured. We also took a few
specimens of Cory don, but it was rather early for
them, and we knew that each day would make them
more plentiful.
In the evening, by beating the neighbouring bushes,
we obtained A. ornata, emarginata, amataria
vemaria, and procellata. The whole of the week
was just as fine as our first day, and on looking over
our diaries, we had captured one Sybilla, one Syriu-
ga?-ia, seven Albieillata, about twenty Imitaria, and
nine Adippe, and we could have taken as many
Galathea, Paphia, Corydon, and Alsits as we cared
for, not to mention the swarms of Burnet moths and
commoner butterflies which frequented every meadow.
We tried sugar, but with no success, but by dusking
and beating, we had obtained Chrysitis, Urticce,
Derasa, Pinastri, Fidvata, Pyraliata, Didymata,
Albitlata, Rubidata, Trilinearia, and several other
geometers, whilst, settled on thistle-heads in the day-
time, we took a few specimens of Conigera.
We had during the week paid a visit to Box Hill,
and very much we enjoyed the cool shade afforded
by the copious foliage. On arriving at the top a very
extensive view is presented, stretching right away to
the downs of Sussex, the marvellous variety of woods,
rivers, and villages, forming a panorama beyond
description. Height 800 feet.
So far we had had wonderful weather, not a drop
of rain had fallen, and the same bright prospect was-
before us when Monday morning came, and we
decided to go for a walk in Betchworth Park, about
a mile distant from Dorking on the Reigate Road,
in which is a magnificent avenue of lime-trees, and
we were told that had we come a month earlier we
should have found the scent of the bloom almost
overpowering.
The river Mole runs through the park. It is a
dull-looking stream, moderately wide here and narrow
there, deep here and very shallow there. I think
most of the fish to be obtained in it are tench, carp,
eels, &c, those kinds which frequent muddy still
streams. But although the water itself is not very
inviting, the scenery along its banks is very pic-
turesque, especially at this particular spot, where the
foliage of the park sometimes forms quite a bower
over the water. After walking through the park we
came out again into the road, and then across some
corn-fields in the direction of Box Hill, on climbing
the sides of which we were greatly delighted to again
find our friends the wild strawberries in plenty, with
which we regaled ourselves for some little time, thus
we worked round to Burford Bridge, and then home
along the road to Dorking.
In the afternoon we went for a drive to the Holm-
wood, a large tract of common and forest land, south
of Dorking, on the Horsham Road, where a camp
was being held, the white canvas of the tents stand-
ing out boldly against the green of the forest, whilst
about every hundred yards we went we came upon
a fresh batch of geese, which always greeted us
with a quack ! quack ! or hizz ! hizz ! In all our
rambles on the commons we met with these con-
sequential creatures, who seemed as if they were
enjoying themselves while they had the chance. On
we went until we arrived at Ockley, and then back
along quiet country lanes by Abinger and Wotton-

The nut-bushes seemed loaded with the young nuts,
and the banks covered with a profusion of ferns ;
moreover the woods and meadows adjoining Leith
Hill seemed to present an unusually fresh appearance
for the time of year. In the evening we tried
sugaring in the Glory, a wood almost in Dorking,
leading on to the Holmwood ; it was, however,
no good, but on our way back, flying over the
corn, we could have taken as many as we
wanted of Palleus, besides the following insects by
dusking, Hectits, Ocellata, Sambncata, Thymiaria,
Albicillata, and Adustata, and flying round an old wall
we discovered Perla in plenty.
The next day we again went to Ranmer, on our
way turning out swarms of Bipunctata from every
bank. We went down our old glade until we came
to a spot where the wood had only latterly been
cleared, and which abounded in thistles, teasles,
nettles, &c. We sat down for a minute or two to
rest, and found that we had discovered a regular
stronghold for Paphia. They came sailing over our
heads and settled on the tallest thistles, and then
off again to exercise their wings. This sort of
amusement we very much enjoyed ; we also took
several specimens of G. rhamni, and I had the good
fortune to take a battered specimen of Sibylla. We
then went through a gate into a sort of plantation,
with waste ground on the right ; every fresh step we took
turning out a lot of wild rabbits, which were on the
path enjoying themselves in the sunshine. On this
waste land was a great deal of ragwort, and on
inspecting the same we found several larva; of yacoba,
in fact on going a little further the ragwort heads
were quite tinted with their orange-coloured bodies.
Here we also saw a specimen of Aglaia, but we were
not able to get near him, a few T. querciis only
rewarding us. During the week we came several
times to the common, and always found some new
employment in walking along the glades, sometimes
under the shade of the oaks, sometimes penetrating
into the thick, and getting ourselves nicely pricked
with the brambles, listening to the song of the thrush
or blackbird, sometimes hearing the melancholy Coo !
Coo ! of the ringdoves, or pausing to catch the distant
sound of Cuckoo ! Cuckoo ! All these delights are
only to be realized, they cannot be recorded.
Our next visit was to Leith Hill, five miles distant
from Dorking, which was particularly enjoyable.
We walked to Cold Harbour through wooded lanes,
in which the trees sometimes met, forming a beau-
tifully-shaded walk, and being exceedingly pic-
turesque and romantic. Here we had some lunch,
and then commenced to ascend the hill. The path
is very rough, especially for a pony, which we saw
pluckily struggling up. The sides of the hill are
covered with a growth of bracken and furze, with an
occasional plantation of young fir-trees. On arriving
at the top and going up into the tower, a magnificent
view presents itself ; and it is said that on a clear
day twelve counties are visible. We could distinctly
see without the aid of a glass the clump of trees at
Chanctonbury Ring, near Worthing. A few children
were scattered here and there gathering the whortle-
berries which grow on the hill, and from which they
say a very delicious jelly is made. Leith Hill is
993 ft. above the sea-level, and is the highest eleva-
tion in this part of the country. Like everything
else, this sort of thing was not to last for ever, as the
time was quickly passing on, and rapidly bringing
our holiday to a close ; so we resolved to have a
good turn at collecting for the two or three remaining
days. During this time Colias Edusa had been
coming out in plenty, and we captured as many as
we wanted, flying over the lucerne fields near the
railway-station, and amongst them were fortunate
enough to come across two Helice. I also took one
Ochroleicca settled on a thistle-head. We obtained
moreover Cardui and Rhamni in fair abundance,
besides turning out Semele on the dry hill-sides. If
we had only had good sugaring we should have had
a very successful holiday in an entomological point of
view, for novices like ourselves ; but we were far
from discontented, as the lovely weather and variety
of the country would require a very peculiar indi-
vidual not to appreciate. Our only regret was
that we had got through the time allotted to us ;
and it was with somewhat of chagrin that we said
adieu to the shady woods and open meadows, and
returned once more to our usual vocation, a great
deal the better both in mind and body for our fort-
night's holiday. A. J. R.
LIVE TOADS IN LIMESTONE ROCKS.
I HAVE lately been working geologically among
the culm-measure limestones of North Devon, and
there I heard the oft-repeated story of a live toad
having been disinterred from the solid rock. Un-
fortunately it was an event of the past, and I did not
see either the toad or the rock from which he came.
But I can testify to the good faith and general in-
telligence of my informant, who assures me that he
saw the toad, which had just been wantonly crushed
by the quarrymen, and that he also saw the mass
of rock which had been cleft, and the cavity in which
the toad had been. He further assures me that the
rock was perfectly solid, without flaw, joint, or per-
foration of any kind leading to the cavity. He has
no reason to think that the quarrymen intended to
deceive him, and he himself evidently intends faith-
fully to describe what occurred.
At about the same time that this information was
given me, a similar case was reported to me from the
limestone near Totnes, in South Devon. In this
instance the quarryman who saw the toad taken from
the rock has been well-known to me for years as a
steady honest man of superior intelligence. But here
again I was not an eye-witness, and can only repeat
200
HARD W1CKE 'S SCIENCE- G OSSIP.
what I am told. I am, however, firmly convinced
that the man himself fully believes what he reports.
Concurrent testimony, if sought, would be obtained
from many independent sources, and yet I find that
scientific men are generally disposed to treat such
stories with simple incredulity. But surely the
phenomenon is worth investigation. No British jury
would believe that the quarrymen in all parts of Eng-
land were leagued together to impose upon the public ;
nor would any man of science believe that the toads
were really imbedded in homogeneous rock. Until
a better solution can be offered, I may venture to
suggest the following : —
It is well-known that all limestone rocks abound in
fissures and joints, which may be and often are filled
up with angular debris. At Westleigh, in North
Devon, there are many thick beds of breccia alter-
nating with highly inclined and vertical strata, the
breccia being just as hard and serviceable as the
stratified rock. In some cases where the cementing
carbonate of lime has not been coloured,* the two
varieties of rock might not be distinguished at first
sight, even by a geologist, still less by an ordinary
observer. These breccias may be of any post-car-
boniferous age, and may be still in the process of
formation.
We have then only to imagine our toad to have
accidentally or purposely got into a fissure, and to
have there found himself in what (from a batrachian
point of view), we may call comfortable quarters.
There, being of a phlegmatic temperament and of
sedentary habits, he stood (or rather squatted) his
ground, indifferent to the angular fragments which,
from time to time, fell around him. Like Horace's
" Vir Justus ac tenax propositi," of whom it is further
said, " Si fractus illabitur orbis Impavidum ferient
ruinre," so he also was not shaken in his sense of
tenant's right by the "wreck of matter" which, in
the form of rock-debris, threatened his cranium.
Dripping water bearing carbonate of lime by degrees
would change his home into a prison, cementing the
congeries into the semblance of homogeneous rock.
How long a toad might live under such conditions,
I do not venture to conjecture, but the many instances
of modern conglomerates, and the stalactites which
rapidly collect under newly-built bridges, would argue
that the process of forming such a breccia as I have
described need not necessarily have occupied many
years. I submit, at least, that the independent testi-
mony of quarrymen from many places remote from
each other ought not to be set down as mere inven-
tion or exaggeration, but should be accounted for as
above, or upon some better hypothesis, if such can
be suggested. W. Downes.

THE BIRTH OF A ROTIFER.
THE water from which my Rotifer was taken had
been standing for some months in one of the
marine tanks at the Brighton Aquarium, and was
filled with dead mussels. The body, which was sur-
rounded by a single row of filaments, resembled a
Paramecium, but was longer and not so broad.
The head was blunt, and was beset with strong
cilia, amongst which were three or four long fila-
ments. This part of the animalcule was sack -like,
and a broad sinus formed the mouth, which was
fringed with cilia smaller than those at the margin of
the head. A row of globules, about thirteen in
number, commencing from near the mouth, extended
the whole length of the body, within which could be
traced three distinct bulbous sacks, connected by
alimentary canals ; near the posterior extremity a
single dark spot was observed.
Fig. 154. First appearance of Rotifer.
Fig. 155. Rotifer in act of emitting young.
The integument was marked with a fine series of
horizontal lines. The animalcule had a peculiar
mode of feeding. It first rubbed its gelatinous body
against a mass of vegetable matter with which it
happened to come in contact, to disintegrate it, as it
were, and then pushed its head amongst the debris,
grovelling like a pig, and using its cilia to draw the
particles into its mouth. On moving the stage,
another of the species was brought into the field.
The upper part of the head was shrunken and dead,
and was almost separated from the body ; but round
the lower part of the gullet the cilia were in rapid
motion. The other part of the body was perfectly
quiescent, even to the filaments, and was compressed
and colourless. About midway down the Rotifer, a
slight swelling commenced, which gradually increased.
It then burst, and a violent disruption took place,
which resembled a mimic Vesuvius. A jet of water
issued from the orifice, followed by six minute, pellu-
cid, oval creatures. Their motion was at first very
sluggish, but they soon gained sufficient vital energy
to prove beyond all doubt that they were endowed
with life.
The young lingered over the body of the mother

for some time, and then, joining a community of
atoms no larger than themselves, were lost beyond
all identification. The vortex round the head of the
parent ceased. The animal slowly dissolved through-
out its entire length ; and, in a few seconds, became
one indistinguishable mass of inanimate matter.
Having fulfilled its mission, it ceased to exist, leaving
nothing but the integument, which retained its pristine
outline. John Davis.
TERATOLOGY OF A CABBAGE-LEAF.
A CORRESPONDENT has kindly forwarded to
us a specimen of cabbage-leaf, showing one
of the most peculiar malformations we have seen.
Fig. 156. Malformation of Cabbage-leaf: two-thirds nat. size.
The midrib of the leaf has become detached about
an inch from the base, and exists as a separate
stalk, exactly simulating an ordinary flower-stalk.
Meantime the true leaf only just shows in its vena-
tion the place where the midrib ought to be, whilst
the laminae of the leaf are abbreviated so that the
stalk extends nearly a couple of inches beyond the
apex. At the summit of the stalk (or detached mid-
rib) the lamince have again grown, but the two
external edges have been fused together in growth,
so as to present the appearance of a gamosepalous
calyx. We have shown the specimen to several
botanists, who had not the slightest idea of its being
a malformed cabbage-leaf. The accompanying sketch
by Mr. J. W. Buck, B.Sc, is two-thirds the natural
size of the specimen. On page 113 of "Vegetable
Teratology," Dr. Masters figures and describes a
similar malformation in a lettuce-leaf, and mentions
the cabbage-leaf as occasionally liable to malforma-
tions of this kind. The fruit of the rose, he remarks,
is only the dilated end of the flower-stalk, in which
the true carpels become imbedded. "Between such
a case and that of a peltate leaf with a depressed
centre, such as often occurs to some extent in ATehan-
bium, there is but little difference." These mal-
formations thus throw interesting sidelights, not only
on the origin of such pseudo-syncarpous fruits as the
rose, but also on the peculiar leaves of Sarracenia,
Cephalolns, Aristolochia, and others.
HOW TO START A NATURAL HISTORY
SOCIETY.
WE have repeatedly been applied to for in-
formation how one or two individuals fond
of natural science should proceed in starting or
founding a society for the furtherance of its study.
We have had some experience in this matter, and
can honestly say we know of few organizations which
may be made so mutually helpful or so socially plea-
sant for such a small outlay of money. What Mrs.
Glass said of the hare is true of societies of this kind.
You must first catch one or two people interested in
some department of natural science. There are few
towns or districts in Great Britain now where there
does not reside some one who is a Fellow of one of
the learned societies, and who has so far won his
spurs. Such an one is generally willing to act as
president, and to throw the weight of his influence
into the scheme. The secretary should always be
selected on account of the greater interest he takes in
science, for we regard a good secretary as really
more useful to a society than a president. The
meetings of a young society should not be held too
often, or there will soon be a dearth of papers.
Once a month, in the winter, is quite often enough ;
and one paper only each night, the rest of the
evening being taken up with discussion. It is a good
practice to encourage members to bring something
at every meeting for exhibition — something which
strikes them as singular, and which they do not under-
stand. This practice causes members to look out for
objects, and develops the observing faculties. It
is also useful in raising discussions and oral descrip-
tions at meetings, and perhaps, eventually, in origi-
nating papers.
>02
HARD Wl CKE *S S C1ENCE - G O SSI P.
New societies should not aim too high. Let them
accept papers on any subject connected with natural
history, and endeavour to raise good discussions on
them. The subscription fee should not be too much —
never more than half-a-crown or five shillings a-year,
or the pocket will affect the members. We have in-
variably found the most prosperous societies and clubs
those which charged the smallest subscriptions. In
almost every village, to say nothing of towns, there
would be little difficulty in hiring, or even in obtain-
ing free, some school-room, either in connection with
church or chapel. Indeed, numerously attended
churches and chapels have started scientific clubs of
their own, so beneficial has it been found to found a
society that will find intellectual work for young
men. The rules of a young club should be as few
and simple as possible, and as free from penal
clauses. At first, it would be as well to think of
nothing but mutual instruction in scientific matters.
Afterwards, the careful study and cataloguing of the
plants, insects, birds, fossils, &c, of the neighbour-
hood might be considered.
Some very young societies are ambitious early to
appear in print, and to publish their own "Trans-
actions" or "Proceedings." This is well enough
when there is anything really worth publishing, but
even then there are plenty of magazines willing to
publish such papers, and able to give them a wider
publicity than they could have obtained locally.
Young societies soon find printing and publishing
very expensive, and it is frequently a source of vexa-
tion to the members. This matter, therefore, should
be left out of consideration when it is intended to
start a new society. If there be any surplus money,
let it be spent in purchasing such high-priced stan-
dard books or magazines as would perhaps be beyond
the pockets of many members, and these could be
circulated in the usual manner. We have known
successful instances of members specially combining
to circulate such books among themselves, in addi-
tion to any which might be obtainable from the
society's library. The summer excursions should
not be numerous —not more than two or three during
the season. Half a day will be often found long
enough to do a great deal of real good work in. If
the society limits its members to the male sex, there
is no reason why they should not enjoy the pleasure
of ladies during the summer excursions. To con-
clude, the chief things to be considered are, (i)
earnest study (no matter by how few, for the
numbers will increase if the original members can
only "learn to labour and to wait") ; (2) an absence
of any pretension to intellectual superiority ; (3)
an endeavour to make the membership as cheap
and inexclusive as possible, so as to throw the
society open to all classes — the only specification
being a love for scientific subjects, even if there
be not always the means or the opportunity to
cherish it.
"BRUCE," THE MANCHESTER FIRE
HORSE.
AT the latter part of the spring of 1864 " Our
Bruce " was born ; he soon began to show
signs of a very promising hunter, of over sixteen
hands, and in due course commenced his training for
the chase. At five years old he had grown to a
beautiful animal, very docile and tractive — his mottled
grey coat the pride of the groom and the admiration
of his master. "Our Bruce," in the hunting-field,
once stumbled, and, in consequence, lost the con-
fidence of his master, who disposed of him to the
Manchester Carriage Company. In the early part
of the year 1870, he was sold by the Carriage Com-
pany to the Manchester Corporation for the fire-
engine department, and commenced his duties on
the 24th March. His general appearance, and kind,
tractable, willing ways were soon noticed by the
firemen, and in less than a month after he joined
the brigade he was the favourite of the whole estab-
lishment, having pretty well the free run of the yard,
in which he caused much diversion by his singular
and funny ways. He was always full of innocent
mischief, and one of his greatest delights was to
chase the men about the yard. It sometimes hap-
pened that he was let out for a gambol when the
children were playing. On such occasions it was
most interesting to notice how careful he was in not
going too near them. At other times, when the
engines were in the yard, he seemed not to forget
his early training as a hunter, and would amuse him-
self by jumping over the poles. When tired, lie
would lift the latch of the door and go into his
stable, and just as easily, after a rest, when the stable-
door was closed, he would let himself out again, or
knock loudly at the door to attract attention. Near
the stable-door there is a water-tap with a revolving
handle. "Our Brace " would turn the handle with
ease and help himself to a drink. It sometimes
happened that a hose-pipe would be attached to the
tap ; this would not cause him the least inconvenience ;
in such a case, after turning on the tap, he would lift
up the end of the hose-pipe with 'his teeth and hold
the end in his mouth until he had satisfied his thirst.
Many curious anecdotes could be told about our pet :
how on one occasion he picked up the end of the
hose and wetted one of the firemen who had offended
him ; how, at a fire, he would stand amidst the greatest
noise and excitement, with showers of sparks falling
around him, and on his beautiful coat, only to be
shook off ; and at other times completely enveloped
in smoke ; but there was no shying or fretting under
fire or smoke with "Our Brace." He seemed to
know that he had brought those who would fight
that ruthless tyrant fire, and he stood proud and
confident that before long he would return home
with the victors, when, after being refreshed and
groomed, he would again be ready, always first, for
the next " turn out."

For nearly six years "Our Bruce" never missed
going with the first machine, at the end of which
time he was, in consequence of his fine appearance,
and our desire to give him a less active duty in his
old age, transferred from the fire-engine to police-
patrol duty; We did not altogether lose our faith-
ful animal's services, for one of his duties was to
attend fires with the mounted police-sergeant (whose
name was also Bruce) to keep back the onlookers,
which he most effectually did for nearly two years,
during which time he was as great a favourite with
the policemen, rarely leaving a police-station without
an apple, a piece of bread, or some mark of affection.
On the 7th of June " Our Bruce " fell sick ; the
veterinary surgeon was sent for, who pronounced him
suffering from inflammation of the bowels. The usual
remedies were applied, and everything was done to
relieve his pain and make him comfortable, but to no
avail. For three days afterwards he was never left
for a moment, night nor day, and at the end of the
third day he drew his last breath, surrounded by
those who loved him well, and who had been taken
by him to the scene of many a hard fight. A post-
mortem examination was held the following morning
to ascertain the cause of death. A stone (calculus)
six inches in diameter, weighing five pounds eleven
ounces, was taken from his bowels. This was, no
doubt, the principal cause of the disease which led to
the death of the fire horse, " Our Bruce."

BRAMBLES ABOUT LONDON.
By Dr. E. De Crespigny, Author of "A London
Flora."
"In the days when we went blackberrying,
A long time ago,"
WE knew that blackberries were distinct from
dewberries, and no more : happier in our
ignorance then, than we now are in our knowledge,
that there are blackberries and blackberries ; and
that Rulnis pmticosus represents an aggregate of forty
species, regarded by collectors as distinct, besides
varieties. Of these, twenty-eight species are classed
as occurring in the home counties, province III. of
the " Cybele Brit. " (see Compendium) ; but to what
extent they severally prevail there are at present no
records to show. Something, therefore, might be
attempted towards ascertaining the range, compar-
ative frequency, and particular habitats of the more
uncommon kinds, assuming that the ordinary forms
are generally distributed. The difficulty is not so
much in being able to find them, as in the ability to
appreciate the small and inconstant shades of difference
by which many of them are to be distinguished, not
only from each other, but also from intermediate
forms or variations ; because, placed as all are now
on the common footing of separate species, we are no
longer at liberty to assign any values to the difference
between what were formerly considered species and
what sub-species; added to which there is, com-
paring the London Catalogue with the books, no
little confusion with regard to nomenclature. The
difficulties in the way of correct diagnosis is only
lessened to a certain extent by arranging the species
into groups or sections ; for unfortunately the lines of
demarkation are by no means distinctly defined, and
in doubtful cases we are at a loss for fixed rules by
which we may be guided in determining to which of
the sections our specimen should be referred.
Brambles are arranged in sections as follows : —
i. Suberecti ; ii. Ccesii ; iii. Glandulosi ; iv. Villi-
caules ; v. Nitidi.
I. Suberecti : type, R. suberectus. This, found in
boggy woods, is a northern plant, and is nearest the
raspberry, R. IJaus, in habit ; it is not found near
London, but R. plicatus occurs in Tilgate Forest,
near Tunbridge Wells, and R. affinis has been re-
ported from Epping Forest. We have not met with
either species ; they may be known by their suberect,
slender, terete stems, furnished with a few weak
uniform prickles, and glabrous leaflets, which are
often arranged in a sub-pinnate manner ; that is to
say, the terminal leaflets are either ternate with two
pair of basal leaflets, or they arequinate with a single
pairs of basal leaflets, but there is no continuity
between the sets. Another characteristic of the
group is a distinct white border to the margins of the
sepals.
II. C.esii. Subsection a : type, R. ccesius. We
venture to suggest that the proper position of this
group is next in order to the preceding one ; with
which subsection a has very much in common. R.
arsiits may be regarded as a trailing form of suberectus.
They are much alike in flowers and fruit, besides
other points. R. ccFsius is readily diagnosed, but
when met with in its more robust form it may some-
times be mistaken for corylifolius. There are several
varieties : tenuis, ulmifolius, &c. The stems are
usually very slender, terete, and glaucous, furnished
with many slender unequal prickles ; leaves ternate,
terminal one often lobed ; sepals setose, and clasping
the glaucous few-grained fruit. Plentiful by the
banks of the Thames about Kingston, and in one
form or another not unfrequent on damp, shady ditch -
banks, which are seldom cleared or trimmed, at a
little distance from the environs. It grows also by
the Bave stream in the hollow W. of Wimbledon
Common. Subsection^: type, R. corylifolius. This
is a very common and also a very variable plant.
Its characteristics, however, are so well marked that
it can seldom be mistaken for a bramble of any other
section. The stems are terete, although strong
young shoots are sometimes obscurely angled ;
smooth, of a greenish subglaucous hue, somewhat
rufous when old, furnished with uniform weak
prickles and a few subsessile glands ; generally

prostrate when unsupported ; the leaflets are broad,
doubly dentate, serrate, or biserrated, and remark-
ably imbricated, owing to the lateral pair being sub-
sessile, and the basal ones entirely so ; rugose above,
pubescent below;* sepals ovate and tomentose ;
petals rotund white, sometimes pale blush (in pur-
pureas they are pinkish) ; the panicle always corym-
bose ; its flowering is both early and prolonged. It
are somewhat elliptical. They may be found on damp
shady places and ditch-banks. We have gathered
them in a lane between the "Spaniards" (Hamp-
stead Heath) and Hendon.

of subdivision, a. Transition of the prickles into

is a common hedge bramble about London. On the
Finchley-road, near the station, for instance, and in
the lanes leading to Willesden, it is plentiful. The
leaves are often ternate by abortion ; that is to say,
the lateral pair are two-lobed, a peculiarity by no
means confined to this species. R. Balfourianus and
R. althaifolius are straggling forms belonging to this
section, with large flat leaves, usually ternate, and
large arsius-like flowers. In althaifolius, the leaves

seated on the veins ; even when glabrous below th; principal
veins are never quite free from hairs. In brambles with strong
arching stems, such as the nitidi and larger species of glandulosi
and villicaules, the veins and pedicels are also furnished with
small hooked prickles.

rarely quinate ; of a rhomboidal or ovate form, with
biserrated margins ; sepals very glandular and fur-

pale blush ; the panicle broad-topped ; pedicels very
slender, prickly, and glandular. Frequent in hedges,
in the lanes and roadsides about London. R. Gun-

however, are obovate and not contiguous ;
not narrow, as in R. glandulostis ; and the

THE LAND AND FRESHWATER
SHELLS OF TASMANIA.
By W. F. Petterd.
ALTHOUGH the descriptions of many
species of the Conchological Fauna
of Tasmania have appeared scattered
through various scientific publications, I
do not think a brief and condensed sketch
of what is up to the present known concerning the
land and freshwater shells of this island will be
altogether an unacceptable contribution to the
columns of Science-Gossip, for I feel assured it
must number many among its readers that take an
interest in Conchology. My design in writing the
present paper is not to enter into elaborate and ex-
haustive details of the description and distribution of
the various species, but to give a general idea of the
land and freshwater shells of this far-off land. Tas-
mania is situated about 120 miles south of the south-
eastern corner of the Australian continent ; it is 165
miles average length and 155 average breadth, and,
exclusive of adjacent small and numerous islands
and indentations, has about 700 miles of a coast-line
HARD WICKES SCIENCE- G OS SIP.
207
of diversified aspect, often rugged in the extreme,
their beautiful snow-white sands stretching for miles.
It is watered by numerous streams, which meander
through its wild mountain-ranges and undulating
hills that intersect the island, mostly covered with
dense vegetation of gigantic trees and almost im-
penetrable undergrowth. These natural barriers and
the physical character of the island, by dividing it into
districts, may to some extent account for the extremely
restricted localization of many of the species of land
and freshwater shells, which is very marked and
noticeable to the conchologist, although the disper-
sion of animal life in the other departments of zoology
is not so generally restricted. The marine species
have received much attention, and the richness of the
Tasmanian coasts is well known among the lovers of
nature, comprising, among its numerous members,
some of the most gorgeous and attractive of the
collector's cabinet. Among the number may be
mentioned Cyprceaovida umbilkata, Valuta fusi-
formis, V. manulla, V. papulosa, V. Sclateri, and
V.Augasi, with the beautiful Venus lamellata, Tryonia
viargaritifera, Phasianella Australis, and many others
of equally attractive appearance.
Recently many new species have been described in the
Proceedings of the Royal Society of Tasmania, mostly
from dredging operations on the coast, comprising
species of genera hitherto unrecorded from this island,
and some even from Australia. They include new species
of Murex, Trophon, Ranella, Siphonalia, Dentalium,
Gibbula, Cyclostretna, Scissurella, Margmella, Comes,
Pleurotoma, Columbella, Conionella, Styloptygma,
Stylifer, Rissoa, Mytilus, Gouldia, Kellia, Macro-
schisma, Turbonilla, Clanculus, Diloma, Daphnella,
Fustts, T'riforis, Nalica, Crossea, Liolia, Acmcca,
Callista, Myadora, Gasterochana, and a new Aslele,
a genus of Swainson's, described by that talented
naturalist when in Tasmania, in the Proc. Royal
Society of Tasmania for 1854.
The land shells of Tasmania have received a fair
share of attention from Australian scientists, ^and
numerous species have been described by Dr. Cox
and Mr. Brazier. The former, in his monograph of
Australian land shells, enumerates twenty-two species
as from Tasmania ; the latter gentleman has
many descriptions in Proc. Zoological Soc. of London
(vide Proc. for June, 1870, &c), and a general cata-
logue was published by Mr. Legrand, in 187 1, of
all the sorts known up to that year. Since then
several additional have been described in the Proc.
Linnean Society of New South Wales, and Proc.
Royal Society of Tasmania. The number of de-
scribed species now known is eighty-seven, dis-
tributed in the following genera : Bulimics 2 ; Vitrina
2 ; Succinea 2 ; Truncaiella I ; and Helix 80 ; and
during my last collecting tour in the northern portion
of the island I obtained twenty-two additional
species, seven Helices, which are as yet undescribed.
The Helices are strikingly different from those of the
mainland of Australia, although I have collected
several undescribed species in Victoria with a some-
what general resemblance to some of the Tasmanian
species ; nevertheless, the general characteristic
difference is very distinct and noticeable. The number
of species, more especially of the smaller forms, is
surprising, particularly when it is taken into con-
sideration that but a very small portion of the
island has been searched for land-shells, for the
workers in natural history are extremely few in
number. I have never, to my recollection, collected
in a fresh locality without finding one or more new
species, which is certainly a great stimulus for further
investigation in this attractive department of science,
so that we may reasonably anticipate a great augmen-
tation in their number as the unsearched localities
are worked up.
Among the most remai-kable sorts may be men-
tioned Helix Launcestouensis, Reese, a fine large
and unique form, of a black colour, with a broad
yellow band on the under surface. It is confined to
the dense myrtle forests in the north-eastern portion
of the island, where it is comparatively plentiful
about decaying vegetable debris. Helix lampra,
Pfr., a pretty glossy wild chestnut shell, found
generally distributed along the northern coast-line.
Helix lamproides, Cox, which reaches occasionally
the size of //. Launcestouensis, and is possibly the
H. bisulcata of Pfeiffer.
Helix dispar, Brazier, is the only species recorded
with a tooth in the interior of the aperture, either
from this island or Australia.
Helix vitrinaformis, Cox, a curious form dis-
covered by myself on Mount Wellington, with a
peculiar Vitrina-like appearance, and Helix Weldii,
Tenison Woods (Proc. Royal Soc. of Tasmania,
1877), a'very interesting minute shell from Circular
Head, as it is the only reversed Helix recorded from
Australasia. The majority of the remainder com-
prise a group of small Helices very different from
those of any other part of the world, of which only
three species have been ascertained with any cer-
tainty to be common both to the mainland and
Tasmania; viz., H. Sydneyensis, Cox, which is
abundant in cellars and such-like places in Sydney,
New South Wales ; Auckland, New Zealand ; and
similar localities in Launceston and Hobart Town.
It may possibly be the European H. cellaria, intro-
duced by some means. H. Alexandra; Cox, which
is abundant in gardens about Sydney, New South
Wales, and like localities around Hobart Town.
This I consider the acclimatized H. costala of
Europe. The other is H. Norti, Cox, which is
generally distributed through Southern Australia,
and may have been brought over by accident with
plants, or by some such means. The identification
of this species is somewhat doubtful, for I think,
upon careful examination, the Tasmanian specimens
will prove to be a distinct species.
208
HARDWICKE'S SCIENCE-GOSSIP.
Of the Bulimi, B. Dufresnii, Leach, is an unique
form, distantly represented by B. Angasianus, Pfr.,
in Australia. It is widely distributed, and varies
much in general coloration and size. The larger
specimens are found in the dense jungle, and the
smaller dwarf varieties in the more open and dry
parts.
B. Tasmantcus, Pfr., is allied to B. Kingi, Gray,
of King George's Sound. It is distributed around the
northern and eastern coasts, always near the sea,
clustering on trees and rocks, almost invariably in
considerable abundance.
Vitritia Milligani, Pfr., is one of the finest species
of the genus ; it is of a beautiful shiny black colour,
and is truly the gem of the land shells of the island,
for its remarkable colour and size render it very
attractive. It represents in Tasmania H. attramen-
tasia of Victoria, Australia, and H. Busbyi of New
Zealand. The animal is of a bright and showy red
colour. It is confined to the western portion of the
island, where it is tolerably plentiful in the dense fern
scrubs, particularly about the Duck River.
V. Verreanxi, Pfr., the only other species, is gene-
rally distributed, aud reaches a somewhat large size
in favourable localities. I obtained a species in Gibb's-
land, Victoria, bearing a close resemblance to this
shell.
Like the land species, the fresh-water are very
local in their distribution, almost every creek and
mountain-stream affording a distinct species. The
Rev. J. T. Woods, in a paper read before the Royal
Society of Tasmania, enumerated 32 species ; that is
to say, 28 univalves and 4 bivalves, belonging to the
following genera: — Physa, 12; Limnea, 4; By-
thinea, 7 ; Ancyhts, 2 ; Pomiatopsis, I ; Planorbis, I ;
Assiminm, 1 ; Unio, 1 ; Pisidium, 2 ; Cyclas, 1.
More recently he has described a species each of the
genera Valvata and Ampitllaria. Mr. Brazier, in
the Pro. Linnean Society of New South Wales for
1876, describes two species, which he places in the
genus Amnicola, — A.Petterdiana and ,4. Simsoniana,
and he has also described, in the Pro. Zoological
Society of Londonz two species which he assigns to
the genus Pahtdestrina.
The Physa and Limnea are of the ordinary forms,
having mostly close representatives in the mainland
of Australia ; and the same may be said of the re-
mainder, with the exception of two, viz., the Ancylus,
A.Cumingianus, Bourgingnat, a remarkably fine and
pretty species, — in fact, the finest of the genus known
up to the present time. It is peculiar to the Upper
Derwent River, in the southern portion of the island,
and is without doubt the most remarkable and inte-
resting of the fresh-water shells of Tasmania. The
other is a small shell, which the Rev. J. T. Woods
has placed in the genus Ampullaria, to which genus
it very doubtfully belongs, for, in all probability,
upon close examination of the animal, it will be
found to require a sub-genus, if not an entirely new
genus, for its reception. The specimens were col-
lected in a creek on the northern coast of the island.
Several species still remain undescribed, and no
doubt, as further investigation proceeds, many more
novelties will be brought to light in this highly inte-
resting portion of natural science ; as it is, the number
of species now known is great for its comparative
small size. Still, much remains to be done before we
shall have a complete and exhaustive knowledge of
the land and fresh-water shells of Tasmania. Should
this short and rough sketch prove of interest to the
readers of Science-Gossip, I shall be only too
happy to contribute something more concerning the
conchology of Australasia.
MICROSCOPY,
An Improved Wax Cell. — The following plan
of mounting in wax is a modification of that sug-
gested by Professor H. L. Smith, of New York
(Science-Gossip, December, 1876). To my mind
it possesses two great advantages over that of the
professor, being cheaper and more easily accom-
plished. Into the centre of a clean glass slip place
one of Pumphrey's vulcanite rings, and into this put
a few chips of white wax ; then hold the slip over
the flame of a spirit-lamp until the wax is melted,
and set aside to cool, taking care that the ring does
not slide out of position. When well set the wax will
be found to have formed a capital cell on the inside of
the ring, and to have filled up the angle formed by
the outside of the ring and the glass slip. This form
is meant essentially for opaque objects, but it can
be easily made available for transparent mounts by
placing the slide upon the turntable, and with a
broad-pointed scalpel turning out the centre of the
wax cell. An exceedingly neat opaque mount is
made by filling up this central space with asphalte
or other black varnish whilst it rests on the turn-
table. To fix the cover-glass, rub the end of a piece
of warm wax round the upper surface of the vulcanite
ring, when sufficient will be found to adhere for the
purpose; place the cover in position, and pass a
heated iron round the edge, and the whole process is
complete. In this way a great many objects may be
mounted, ready for the cabinet, at a single
sitting, which for neatness, durability, and sim-
plicity of construction are unrivalled. — H. C. Crew,

Quekett Microscopical Club. — The 13th
annual meeting of this flourishing society was held
at University College on July 26th, Hemy Lee,.
Esq., F.L.S., President, in the chair. The report of
the committee briefly reviewed the work of the past
year, and congratulated the members upon the con-
tinued prosperity of the club in every department of
its work. A large number of books had been added to

the library, 185 slides had been presented to the
cabinet, the meetings had been well attended, and
many valuable and interesting papers had been read.
49 new members had been added to the list during
the year, making the present number 562. The
treasurer's statement of account was also presented to
the meeting, and showed the satisfactory balance in
hand of £106.1 3s. 5th The president then delivered
the customary annual address, taking for his subject
"The commercial application of the microscope,"
in the course of which many interesting instances
were cited to show how the skilful application of the
microscope had proved of great value in the settle-
ment of important questions of social and commercial
interest. Much good counsel was also given to the
members as to the future usefulness of the club, and a
well-merited tribute was paid to the honorary secre-
tary, members of the committee, and officers, to whose
efficient discharge of their various duties so much
of their success was due. Votes of thanks were
unanimously passed to the president and officers of
the society for their services during the past year, also
to the council of University College for continued per-
mission to meet in that building ; and an announcement
that a donation from the funds of the club of twenty
pounds had been voted towards the building fund now
being raised for enlarging the college, was received
with cheers. Some further interest was also excited by
the presentation of a valuable gold watch to Mr. R.
T. Lewis, as a mark of appreciation of his services as
honorary reporter since 1866. Dr. Harkness, of San
Francisco, having been introduced to the meeting as
a distinguished foreign visitor, was requested to con-
vey the greeting of the club to the microscopical
society of San Francisco, and briefly acknowledged
the compliment on behalf of himself and his colleagues.
The result of the ballot for officers and council for
the ensuing year was as follows :— President, Professor
Huxley ; Vice-Presidents, Dr. Matthews, Messrs.
Henry Lee, C. Stewart, and T. C. White ; Trea-
surer, Mr. Gay ; Secretary, Mr. Ingpen ; Foreign
Secretary, Dr. M. C. Cooke ; and to fill four vacancies
on the committee, Messrs. F. Crisp, A. D. Michael,
E. T. Newton, and F. Oxley.
A Theoretical Limit to the Apertures of
Microscopical Objectives.— At a recent meeting
of the Royal Microscopical Society, Professor Stokes
read a paper on the above subject, in which he
showed that theoretically a pencil of rays from a
radiant in glass (or under equivalent conditions) of
1800 could be refracted by a single refraction at a
spherical surface so as to present to the second lens
a pencil of about 8l° free from spherical aberration ;
and, while not asserting the possibility of utilising the
whole of the pencil of 1800 in glass, he thought a
very large part of it might be available in a practical
construction,— a far larger part than can be used in
dry lenses.
ZOOLOGY.
Birds' Eggs in Wrong Nests.— The circum-
stance mentioned by Mr. Sharpe in the number for
July must be veiy unusual. Last year, on May 9th,
I found a blackbird's nest with three blackbird's eggs
and a thrush's ; the blackbird was sitting, but I do
not know if they were hatched off. In April, 1873,
I found a coot's nest near St. Albans with seven
coot's eggs and one moorhen's. On going again a
few days afterwards I found an eighth coot's egg and a
second moorhen's, with the coot sitting on them.
These are the only instances I can recollect to have
met with of one species of bird laying in another
nest, besides the ordinary custom of the cuckoo, during
several years' experience of birds'-nesting. Single
eggs of various birds, partridges, thrushes, and black-
birds, more especially, are frequently found dropped
on the ground, probably either because the bird has
not finished its nest in time, or else because its nest
has been torn out. In pulling out an old partridge's
nest some years ago, from which all the young birds
had run (by the way it was, as I should say they
usually are, rather elaborately concocted of dead
leaves, grass, &c.) ; in the materials I found an egg
which had evidently been laid while the nest was in
making, and had been covered up so effectually by
the lining that it was addled. I have also a red-
start's egg which my brother found in a corner of an
old tree, between the trunk and a branch, where it had
evidently been dropped for lack of a nest. Very
probably the starlings not having a nest of their own
ready, made use of their neighbour's from the same
cause.— A. F. Griffith, Cambridge.
Appearance of Papilio Machaon.— On the
25th of June, 1876, the weather was warm and fine.
At noon on that day P. Machaon made its appearance
out of the pupa ; the wings were developing at the
time. Another machaon emerged from the pupa just
before 8 a.m. on the 25th June 1878; its wings
were fully developed ; the weather was warm and fine.
Both imagos emerged on the same day of the same-
month in different years. This may be of interest to
those who notice the influence of insects. The usual
month for its appearance is May.— R. A. Dent.
Testacella Haliotoidea I have lately found
in considerable abundance in my garden ; they are
generally found whilst turning up the ground. The
nearest recorded locality I believe to be Taunton, in
Somerset. I have some in confinement, and have
been watching their habits, which are very interesting.

BOTANY.
The Pronunciation of Scientific Names.—
Cordially agreeing with the principles laid down by
Mr. Charles Browne, I only write once more on this
subject with reference to three names mentioned by him.

HARD WICKE 'S SCIENCE - G OSS I P.
— Veronica, Clematis, and Gladiolus. Not presuming
to give an opinion as to the origin of the legend and
name, or name and legend, of the saint who bears a
name derived from the Latin vera and the Greek
eikon, I venture to think it highly probable that, as
a plant-name, Veronica is simply a corruption of
Betonica, and is therefore rightly accentuated on_the
second syllable. Clematis is now rapidly giving
place to the more natural, as well as the more accu-
rate, Clematis. Gladiolus is no worse than Gladiolus.
The probably classical alternative, Gladjolus, does
not seem to occur to the ordinary gardener's ear. —
G. S. Boulger.
Notes on Silene inflata. — Is it commonly
known that this widely-distributed plant is di-, if
not tri-, morphous ? On Wednesday evening, the
1 2th June, I was forced to seek shelter beneath a tall
hedge from one of those not very seasonable storms
that were this year so disagreeably characterising this
month. Amusing myself by examining various flowers
within my reach, I was struck with the apparent fact
that there were two well-marked forms of the common
Catchfly. In one form the three styles (sometimes
4, sometimes 5) projected fully \ from the tube of
corolla, no stamens being visible. A closer exami-
nation showed that the stamens were present, but
that their filaments were extremely short, seldom
much exceeding the average in length ; and, more
remarkable still, that the anthers were contabescent,
i.e., dry and shrivelled, containing no pollen. In
the other form the stamens projected \, while the
styles were rarely visible. On pulling to pieces these
flowers, however, the styles were found more or less
closely oppressed, and evidently quite immature.
Further examination showed that this form was
decidedly proterandrous ; for, though the stamens suc-
cessively arrive at maturity, commencing with those
on the under side, all the anthers have shed their
pollen before the styles are fully grown. At this time
they are largely exserted, and have their receptive
stigmas widely spreading. I have since passed many
hundreds of plants in review, and find these two
forms about equally distributed in this district, and
wonderfully persistent in the characters mentioned.
There does not appear to be any other striking points
of difference between them, so far as I can at present
determine. The first form is evidently to all intents
and purposes always female ; the second, first male
and then female. I found a very few plants in which
the presence of a few dry anthers (the rest being per-
fect) seemed to indicate a transition stage between
the two. Fertilization must, I think, be brought
about by a small dipterous fly, but how is not very
clear. Its common name of Catchfly is fully justified,
as any one may see who will take the trouble to
examine a number of plants in the earlier part of the
day. Almost every flower will then have a tenant.
I applied to Dr. Morton, who informs me that Sir
John Lubbock quotes Axell, to the effect that there
are three forms, one with stamens only, another with
pistils only, and yet a third with both stamens and
pistil. This scarcely agrees with my observations on
British specimens. If it be correct with regard to con-
tinental species, it is highly interesting as showing
that the modification in them has proceeded much
further than in ours, and along a somewhat different
line, as I can find no tendency to the production of
purely male plants in ours. — J. Hepworth, Rochester.
Variability of Colour in Hollyhocks. — In
the autumn of 1873 I picked up a spike, or rather
stem, of a hollyhock, with ripe seeds, which had been
thrown on a heap of rubbish where it was customary
to dispose of the refuse of neighbouring gardens. It
was kept through the winter, and then the seeds on
it were sown in a row in which the seeds from the
lower part of the spike were sown at one end, those
at the upper part at the other end, and the others
between them in positions corresponding with those
they occupied on the plant. When they had come
up I took one, as from the lower part of the spike, and
planted by itself, and another from the uppermost
part and planted by itself, in perhaps a better situa-
tion. These two plants flowered in 1875. The one
which grew from a seed produced on the upper part
of the parent stem was rather stronger in growth and
earlier in flowering than the other, which I attributed
to its more favourable situation ; for I find that holly-
hocks are very much affected by circumstances.
This earliest flowering plant had blossoms of a crim-
son red, those of the other were of a much darker
colour. The plant with crimson blossoms was the
one from which I took the seed which I sowed in
1876, putting in the ground the seeds from each
flower separately as well as I could, — though I cannot
be perfectly sure there was no error, as a few seeds
fell out of their places on the ground. The plants,
however, which came up in irregular places I de-
stroyed, that I might ensure as much accuracy as
possible. I had expected a difference in habit among
plants raised from seeds proceeding from different
parts of the inflorescence, but did not think of colour.
Of two plants from seeds at the bottom of the spike,
one was left on the seed-bed, where it is now alive,
having made no attempt to flower. This seems to
show the necessity for planting out seedling hollyhocks
in order to their becoming vigorous. The other which
I planted out in 1S77, flowered, as did also four plants
from seeds taken from a lateral spike which sprung
from the. same stem. The seedling plant from the
spike of the main stem produced crimson flowers, like
those of its parent ; the plants from seeds on the
lateral spike were white, with only so much of a
reddish tint as to indicate their parentage. Not
having much ground at my disposal, I did not take
heed of the seedlings from the middle of the spike,
but planted out nine grown from the seeds yielded by
one of the uppermost flowers. Seeds from the upper-
most flowers of all, which were hardly ripened, ger-

minated, but the plants had not vital force enough
to live through the summer. The nine which I
transplanted did not flower till this year, and they
have not all flowered now. Three of them are like
the one from the lower part of the spike one is much
darker, and with many a blossom, having six petals.
The plants from the lateral spike having all white
flowers, that those from the main spike should pre-
sent this richer colour, is what I did not expect.
I suppose the variability displayed in this instance
may be dependent on the fact that the parent plant
from which the seeds were gathered was itself derived
from a seed on the upper part of a stem. But there
is one plant whose flowers are yet unopened ; and
from what I can make out by examining the bud, it
seems as if its flowers would be white. This is so
inexplicable as to make me examine my memory as
to the possibility of errors, but I trust you will believe
me that I cannot imagine any source of error as to
the seeds being those of the same plant, and so far as
I have reason to believe, four plants with crimson
flowers, one with rather lighter, two with deeper,
richer colour, and one whose blossoms will also spring
from seeds proceeding from the same flower. I
enclose flowers, the two white being of plants from
seeds on the lateral spike, the others from the main
spike, the most diverse from one of the upper flowers ;
the one from the lowest flower undistinguishable
from three others. — John Gibbs.
How to grow Filmy Ferns. — A writer in The
Garden gives the following interesting instructions.
Any one interested in these most beautiful of ferns
may grow them successfully without covering them
with bell-glasses or keeping them in warm houses.
In confirmation of this we may refer to a houseful of
them in the Boxhill Nursery. It is of small dimen-
sions and sunk in the ground, so that the eaves of the
roof, which is of octagon shape, are only just above
the surface. It is entered by means of rustic steps
through a narrow span-roofed house, in which hardy
British ferns are growing amongst virgin cork. The
inside of the Filmy Fern-house is lined in the first
place with old railway sleepers, placed in an upright
position, and which support the roof. These are
covered with virgin cork, on which are growing
various kinds of ferns. The Filmy varieties consist
of fine specimens of Trichomanes. Radicans, Todca
Superba, T. Pdlucida, and others are growing in
pots or pans placed on a bank raised three feet or so
above the ground-floor, and extending all round the
house, excepting at the doorway. The side walls
are built with rough stones, among which grow club-
mosses and small ferns. A canvas shading under the
roof is left there summer and winter, but no means
are provided for heating the house artificially.
Inside it is easily kept damp and close, and under
such conditions Filmy Ferns grow remarkably well,
both in summer and winter.
Dimorphism in the Rubiace^e. — Mr. C. B.
Clarke, in a paper on this subject read before the
Linnoean Society, shows that there are two kinds of
dimorphism in the RubiaceiE. The group is known
to be largely dimorphic, the variations consisting
chiefly in the lengths of the style and stamens. Mr.
Clarke's two forms of dimorphism are as follows : —
I. Where the point of insertion of the stamens is
altered, being situate in one form high above the
middle of the corolla tube, and in another form at
the base of the corolla tube. 2. Where there are two
kinds of fruit, one corresponding to a sessile flower,
and another to a peduncled flower.

been called for, and has just been published. The
author has corrected various errors which almost un-
avoidably creep into a work of this kind, touching as
it does on such a multiplicity of subjects. An
American edition has also been prepai-ed and sent
over. The rapidity with which this book has gone
off, whilst gratifying to the author, is a sure token of
the widespread interest taken by the public in the
leading scientific questions of the day.

as many of your readers are aware, is much more
abundant than Macidatum in Jersey, and, I believe,
Guernsey. Orobanche major and Linum perenne. —
Can your correspondent, C. Parkinson, inform me if
the specimens of O. major, " parasitical on ivy," and
Linum perenne," in field," noticed in Isle of Wight,
have been verified, as the undoubted occurrence of
these plants would be interesting? — G. C. Druce.
GEOLOGY,
The Physical History of the English Lake-
district. — This was the subject of a paper read by
Mr. J. Clifton Ward, F.G.S., in which the authortraces
the physical history of the Lake-district from the com-
mencement of the period when the Skiddaw slate
was deposited. To this succeeded the volcanic
Borrowdale series, which is followed, after a physical
break, by the Coniston Limestone. Between this
and the succeeding Silurian deposits there is little, if
any, break. Thus, in the Lake-district, the break
between Upper and Lower Silurian is physically
below the Coniston Limestone, though palseontologi-
cally it is above it. The Old Red Sandstone period
was one of denudation, which was continued into
the Carboniferous period ; and perhaps the whole
district was actually covered by the sea during the
maximum depression of the Lower Carboniferous
epoch. Since then it has probably never been sub-
merged, but exposed to continuous subaerial denu-
dation. The physical significance of the Mell Fell
(Lower Carboniferous) conglomerates received special
212

attention. The author then, from consideration of
the amount of deposition and rate of denudation,
attempts to estimate the period which has elapsed
since the commencement of the record, and sets it
down as 62,000,000 of years. The author then
considers the age of the Skiddaw slates. From litho-
logical resemblances he is led to correlate the Skiddaw
grit with the basement grit in the Welsh Arenig
series, and thus to regard the beds below the grit as
the equivalent of the Tremadoc, and perhaps of part
of the Lingula Flags. The palasontological evidence
for the correspondence of the Arenig series with the
whole of the Skiddaw slates rests chiefly on Grapto-
lites and Trilobites. The author holds that the
evidence from the former is inconclusive, and that
from the latter to some extent contradictory, so that
the physical evidence can in no way be overridden
by it.
StromATOPORA and Loftusia. — Principal
Dawson has contributed a statement of his views as
to the nature of these problematical fossils from the
palreozoic rocks, which are commonly known as
Stromatopora. They are massive fossils, often showing
concentric structures when weathered, and have been
referred by different writers to the corals, to the
Hydroida as allied to Hydractinia, and to the
Foraminifera. Principal Dawson says that Strotna-
topora is " a calcareous, non-spicular body, composed
of continuous concentric porous lamina;, thickened
with supplemental deposit, and connected by vertical
pillars, most of which are solid " ; and he maintains
his old opinion, that " Stromatopora is a foraminiferal
organism and the paleozoic representative of the
Laurentian Eozoon."
Norwich Geological Society. — We have re-
ceived Part I. of the " Proceedings " of this old-
established society, containing a list of all the papers
read before the society since its foundation in 1864,
and abstract of papers read during the recent session.
Ancient Man.— Mr. Thomas Belt, F.G.S., the
well-known naturalist, has made the interesting dis-
covery of a human skull in the section of a railway
cutting in the neighbourhood of Denver, Colorado.
The skull was imbedded in perfectly undisturbed
ground, at about three feet and a half from the sur-
face. Neither the lower jaw nor any other bones were
found with the skull.
Fossil Saurians from the Cape. — Mr. Thomas
Bain, F.G.S., the well-known African traveller and
geologist, has just sent home a splendid collection of
fossil Saurians, many of which are new to science,
tind which have been found in the carboniferous and
triassic formations of Cape Colony. They include
skulls and other remains of DicynoJon, Galcosaunts,
Cynodracon, Oudcnodon, &c.
The Coralline Crag.— Dr. Gwyn Jeffreys, in a
communication to the Linnrean Society, on some
shells dredged in the Korean straits, said that of
fourteen species enumerated, six are now, for the
first time, found living in the North Pacific as well
as the Atlantic. Micinella ovalis and Kcllia pumila,
which had been supposed to be extinct, are shown to
be living in the Korean region. No fewer than nine
of the above fourteen species are Coralline crag fossils.
Dr. Jeffreys holds that these facts support his view,
that Mollusca common to the North Atlantic and
North Pacific Oceans may have originated in high
northern latitudes and have found their way to Japan
on the one side and Europe on the other, by means
of the bifurcation of the great Arctic current.
Our Water Supplies.— Mr. De Ranee has re-
cently read a paper, " On the Palaeozoic and Secondary
Rocks of England as a Source of Water Supply for
Towns andDistricts, " before the Manchester Geological
Society. The paper contains much useful informa-
tion on a subject growing every year more important,
inasmuch as the demand for water increases, while
springs and rivers do not increase. Instances are
given which show how vast are the underground
stores of water within the region occupied by the
rocks above-named. A spring at Barrow-in-Furness
yields, from a depth of two hundred and fifty feet,
thirteen thousand five hundred gallons of water daily.
Nearly three million gallons a day are pumped from
a single well at Liverpool. Three- fourths of the
seven million five hundred thousand gallons supplied
daily to Birmingham is got from wells in the New
Red Sandstone, and the water is described as of a
uniformly excellent quality, and the Perry Well as
one of the best waters for dietetic and domestic pur-
poses ever inspected. Kidderminster has deep wells,
one of which gives one hundred thousand gallons a
day, and yet the present domestic supply is entirely
derived from dangerously polluted shallow wells and
streams.
NOTES AND QUERIES.
Double Egg. — Last year a friend brought me two
hen's-eggs which were joined together in a very
curious manner. The shell was continued at the
apices in the form of a tube connecting the two eggs,
about i in. long and \ in. thick. It formed ap-
parently a perfect communication, being filled with
albumen. The eggs had the appearance of leaning
one against the other, one being quite depressed
where the other came in contact with it, which was
about a quarter of an inch below the points of junc-
tion. I may mention that the shells of the eggs were
very imperfect, be;ng almost soft in some places. — G.
M. Doc, Torrington.
Fungus on Flies. — I have seen a somewhat
similar instance to that mentioned by Mr. E. Wheeler,
but with this difference, that the flies so affected
seemed to be confined to one particular plant. The
plant was withered and dried, and the flies (several
dozens) were stuck about it in all directions, and in
very natural attitudes. I was not at that time botanist
or dipterist enough to identify either the plant or the
I insects, but the latter were very similar in appearance

to the Yellow Dung-fly (S. stercorarius). They
appeared to be all of one species. — IF. H. Warner^
Standlake.
Book on Dragon-flies, &c— Can any reader
of Science-Gossip inform me of a work on the
British LibelluLv (or Dragon-flies) giving plain and
satisfactory descriptions of each species ? The price
must be moderate. Also of a similar work on the
British Ants.— W. H. Warner.
Bees and Paint.— In answer to Mr. Smith's
query on this point I must confess my utter inability
to assign any probable cause for his bees' apparent
fondness for paint— my sole reason for replying to his
question being to draw attention to another curious
penchant of bees, viz., their partiality for smoke. In
early spring, when engaged in gardening operations, I
have often noticed the few bees out at that time
hovering about the weed fires, and endeavouring to
penetrate into them, even when the thick dense smoke
has been issuing in volumes from the fires. This
proceeding has often puzzled me exceedingly. The
genial warmth given out by the fires is doubtless the
attraction.— ^F. H. Warner, Standlake.
Cuckoo (Cttculus canorus. )— Towards the middle
of July I caught in the garden (within two miles of
the centre of Birmingham) a young cuckoo. It flew i
into the greenhouse, and was there caught. I sup- :
pose that the bird was enticed by the great quantity
of magpie moths with which the kitchen-garden
swarmed, so much so that (much as I disapprove of
killing creatures uselessly) I destroyed over fifty cater-
pillars in twenty minutes, and have caught in a net
almost as many perfect insects in the same time. As
I have never seen a cuckoo similar to this one before
I give below measurements and general description :—
Extreme length from tip of bill to end of tail, \i\
inches; length of wing, 9A inches; spread, 20 inches;
third primary, 74 inches ; tarsus, f inch ; and tibia, i±
inches. The plumage was dark iron-grey, except
primaries and secondaries, which were of usual colour
barred with " rufus." The barrings of throat as in
the adult bird, but with a great tendency to very dark
brownish-grey, so as to appear at a little distance to
be almost black. Tail, greyish-black, with "rufus"
markings on inner webs. Iris, dark hazel-brown ;
cere, very light lemon-yellow. Upper mandible of bill,
hair-brown ; lower mandible, lighter brown at tip ;
suffused with light-yellow gape ; and inside of mouth
as usual, orange ; legs and toes, light lemon-yellow,
suffused with pink. — G. T. B.
Dittany.— Your June issue contains a request
preferred by Henry F. Bailey, for information re-
specting "the name of the species of Dittany." It
is an American plant, and is described in Professor
Asa Gray's " Manual of Botany." It belongs to the
Mint Family (Labiat.e). The Common Dittany is
Cumla Mariana. It blooms, with us, from fitly to
September. Gray affirms that the Latin name is of
"unknown origin." The Mandrake is also an
American plant {Podophyllum peltatum). It is a
member of the Barberry family (Berberidacea), and
is the well-known Podophyllum of the Pharmacopoeia,
so valuable a specific in complaints of the liver. We
read, Genesis xxx. 14, that " Reuben went in the
days of wheat harvest, and found mandrakes in the
field." This, I need scarcely add, is an older quota-
tion than any that can be culled from the works
of "our early poets," referred to by Mr. Bailey.—
V. dementi.
Vanessa Antiopa.— \Y. R. Morse inserts a query
respecting the Vanessa Antiopa. This is one of our
commonest Butterflies. There is no doubt that our
specimens have a yellow margin to their wings. At
the same time West wood, to whose beautiful work
I refer your correspondent, says that the margin of
the English specimens is "of a white or -whitish
colour"; also that "the pale margin of the wings
varies to deepish yellow." I was under the impres-
sion that this handsome butterfly had become extinct
in England. — V. Clementi.
COLIAS. — The Colzas mentioned by C. E. B.
Hewitt is a very common butterfly in Canada, and
may be frequently seen, in larg- numbers, fluttering
over ram-puddles on our roads, or settling on their
margin. This pretty butterfly is thus described by
the American entomologist, T. W. Harris : "Their
wings are yellow,' with a black hind border, which
in the females is quite broad on the fore wings, and
spotted with yellow ; the fringes of the wings, the
antenna:, and the shanks are red ; the fore wings
have a small narrow black spot on both sides near
the middle ; the hind wings have a round orange-
coloured spot in the middle of the upper side, which
on the under side is replaced by a large and a small
silvery spot close together, and surrounded by a rust-
coloured ring."— V. dementi, Ontario, Canada.
Lapwings ( Vanellus cristatus). — During the snow-
, storm in the end of March and beginning of April,
the Lapwings, who had returned to their breeding-
grounds, were so pressed with hunger, that some
entered the very houses in search of food. After the
snow had disappeared, the remains of hundreds who
had perished were to be seen. It appears they will
rather die of starvation than leave their favourite
haunts in the breeding season. — W. S. Fyvie.
Intelligence of a Magpie. — Some years ago,
when residing at Stowmarket, I was much struck
with the intelligence of a Magpie belonging to my
next-door neighbour. In a very short time, and
without any effort to teach it on the part of any one,
it learnt the names of several members of my family,
and never misapplied them. This proves that birds,
in acquiring human language, connect the object and
the word, and do not use the latter at random. The
Magpie in question was evil-disposed, and loved to
annoy girls by pecking their feet; but on the approach
of a man or a boy it scuffled away, uttering most
unparliamentary phrases. Its leg having been acci-
dentally broken, it repudiated all surgical aid. It
used to sit on the sound foot and hold up the maimed
limb, looking at it disconsolately, and pecking at the
bandages with continual ejaculations of "D it !"
and died at last worn to a skeleton. — J. W. Slater.
Gigantic Mullein. — When botanizing on the
15th of August last in Spittlesea Wood, near the
place I was gratified by finding an extraordinary
specimen of the Great Mullein ( Verbaseum thapsus)K
It towered up to the height of eight feet and a half,
lifting its spike of yellow blossoms above the sur-
rounding undergrowth, which had been cut down
about three years ago. The total length of the
raceme was three feet six inches, and at the base of
it were two small lateral flower spikes, the one about
six and the other about eight inches in length. Not
far from the spot other specimens were growing,
the height of which was five and a half feet, but
this appeared quite diminutive by the side of its
gigantic fellow. This excessive growth may be
accounted for by the humidity of the season and the
sheltered position in which it grew. The soil is
light gravel, over chalk, with flint.— J. Sau7iders,_
Luton.

HARDWICKE'S SCIENCE-GOSSIP.
Natural History Notes from Ireland. — J
A hen was found in a loft, the flesh eaten and picked
off, leaving as perfect a skeleton as could be desired.
The feathers were lying about. Rats or mice would !
have broken the bones. What animal could have
done it ? A young black rat was killed at Port-
more, Antrim, October, 1877. The gamekeeper j
of Mr. Lowry, Pomeroy House, told me, within the
last two years he has caught, in traps set for rabbits,
two wild cats. I questioned him respecting them,
in case he might have mistaken them for the domestic
cat gone wild, but he stated they were perfectly dis-
tinct, having bushy tails like a fox, and dark grey in
colour. He could hardly be mistaken, as he is con-
stantly trapping the domestic cat. The water-vole
is found near Pomeroy ; the squirrel is also to be
found in the neighbouring woods ; the water-
ousel frequents the streams. — Sam. Arthur Breiian,
clerk.
Rare Birds. — It is with great regret that I read
of the slaughter of rare birds, recorded from time to
time in Science Gossip and other papers. I am
sure no real lover of birds, or true naturalist, would
so ruthlessly destroy birds, as they are destroyed, for
the sake of their skins, whenever they come to our
island. Hardly a season passes but that beautiful
bird the Hoopo appears in Berkshire, and I believe
it would breed, if it were not so eagerly sought after,
and shot.— J. L. H.
The Cuckoo and Water- Wagtail. — Last
August, before 9 a.m., a young cuckoo was observed
perched on a croquet-hoop on the lawn, in front of
our house, full in view of spectators from the win-
dows. A water- wagtail was busily engaged in feeding
it, flying on the hoop each time it fed its strange
foster-child. The cuckoo remained for half an hour
on the hoop, then flew on to a small rockery near,
and from thence to an adjacent railing, the wagtail
following it to both places, and continuing to feed it.
Both birds afterwards disappeared from sight in a
large sycamore-tree. The feeding-time lasted nearly
an hour, the wagtail often going some distance in
search of food for the cuckoo. Our gardener told us
he had noticed before the same birds thus occupied
in the early morning, and had also seen a young
cuckoo being fed by robins in a similar manner. — ■
C. M. Baynes.
A Mysterious Gift. — I remember reading in an
old book (which also gave an account of the first
ascent of the Peter Bolte Mountain, near Port Louis)
an account of a French Creole in Mauritius, who
possessed the marvellous faculty of discerning objects
far out at sea long before they were visible to the ordi-
nary human eye. His powers were repeatedly tested,
and he was officially employed by the governor or mer-
chants there to announce coming ships. He foretold
the arrival of the British fleet, which came to take
possession of the island, several days before it hove
in sight. He stated that he saw these objects upside
down (refracted?) on the horizon, and professed to teach
his art ; but the attempt only proved that he was
possessed of some exceptional natural gift, perhaps
akin to what the Scotch call "second sight." I
was under the impression that the foregoing account
was to be found in one of the volumes of Charles
Knight's "Useful Knowledge Society's Series";
but as I have failed to discover it there, perhaps some
of your older readers can help me. My present pur-
pose is to point out a striking confirmation of the
above narrative, which I have recently met with on
p. 185 of Boddain-Wheltham's "Pearl of the
Pacific." In narrating a visit to the Samoan Archi-
pelago, or Navigators' Islands, he alludes to "a man
now living iu Tutuila, I believe," he says, " but who
formerly resided near Apia, who possessed the extra-
ordinary power of seeing in the clouds, or in the sky,
vessels that were bound for the island. Credible wit-
nesses told me," he continues, "that he had fre-
quently foretold the approach of ships days and days
before their arrival, and had accurately described
them, their rigging, their build, and the weather they
were having— sometimes storm and sometimes calm ;
reference to the ships' logs on their arrival in port
confirming the truth of his statements. He himself
attributed his remarkable visions to the state of the
atmosphere — a sort of mirage — at a certain point
where he took his observations, but I never heard of
'anybody else witnessing similar phenomena." I
thought the concurrence of these totally distinct and
independent accounts worthy of your attention, as
they may tend to establish the general fact of the
existence of a sort of "double sight " in certain gifted
individuals, and thus refer the mysterious power of
the ' ' seer " to a physical rather than a spiritual
source. — F. A. Allen.
A Spider's Instinct. — Dr. J. Lawrence-Hamil-
ton writes from 34, Gloucester-terrace, Hyde-park : —
"The following incident, which I witnessed, may
possibly interest some of your readers : — A boy re-
moved a small spider to place it in the centre of a big
spider's web which was hung among foliage, and
distant some four feet from the ground. The larger
animal soon rushed from its hiding-place, under a
leaf, to attack the intruder, who ran up one of the
ascending lines by which the web was secured. The
big insect gained rapidly upon its desired prey, the
smaller creature (spiders are cannibals, notably the
larger females, who are given to devour their smaller
male lovers). When the little spider was barely an
inch in advance of its pursuer, the small spider cut
with one of its posterior legs the line behind itself, so
that the stronger insect fell to the ground, thus
affording time and opportunity for the diminutive
spider to escape along the ascending rope of the web.
This is not the only fact which seems to indicate that
a spider's instinct may almost equal reason."
How to exterminate Mites. — In answer to
"M. R. D.," in the April number of Science-
Gossip, as to how to exterminate small mites, I
have myself found Keating's Insect Powder quite
successful, after having tried other remedies in vain.
■ — Alfred Patersoii.
Reasoning Power of Dogs. — I should like to
call attention to what I think to be a remarkable
instance of reasoning power in a dog (a setter, if I re-
member rightly). The yard in which this dog is kept
at large is separated from a very narrow lane by a
wall about five feet in height, from the top of which
our four-footed friend is wont to study humanity. On
an interesting occasion he loves to leap into the lane ;
but, when once down, he is unable to jump up again
without a long run, and this is apparently rendered
impossible by the narrowness of the roadway. The
dog, on wishing to re-ascend, begins to trot round
and round in the centre of the path, gradually increas-
ing his pace and the diameter of the circle in which
he moves, until he is galloping round at full speed,
taking a good "kick off" from the stone at each
revolution as soon as his orbit extends from wall to
wall. When he feels that he has acquired sufficient
momentum, he bounds on the top of the wall with
ease. I hold that the above performance involves a
process of reasoning. Instances of dogs pulling bell-
ropes and turning door-handles may result from mere

imitation, but the case in point cannot be thus ex-
plained. This dog, having discovered that a recti-
lineal career was impossible, must have, somehow,
hit upon the idea that he could run round the circum-
ference of a circle to any desired distance, and this
principle he has applied to the solution of the diffi-
culty in a truly ingenious way. — C. W. Carringlon.
Clams. — I have noticed for two seasons past
" Preserved Clams " in tins, on a Liverpool Trade
Circular. I think they are new candidates to gastro-
nomic favour in this country. I take them to be the
" Otter" shell {Lutraria maxima), found so plentifully
on the coasts of Vancouver's Island and British
Colombia. Tridacna gigas is also known as the
"clam," and is, I believe, eaten, but its habits
render it difficult to procure in large quantities. The
" Otter" shell on the other hand is known to be one
of the staple foods of the Indians of the North-West
Coast, and J. K. Lord tells us that it is, in fact, a
"molluscous cereal," which the squaws dig in
summer from the sand and mud-banks of the coast,
and dry and smoke in the interior of their dusky
wigwams for winter use. I have not tasted the
"preserved" clam, and cannot therefore speak of
their edible qualities, but Mr. Lord's experience of
"smoked" clam does not appear to have been a
pleasant one, as he compares it to chewing " good
old tarry rope yarn." Are any of your readers able
to speak of its worth as an addition to our food
stuffs? — IV. A. Cairns, Leominster.
Preserving Animals. — I, like "W. G.," have
met with an article mentioning the method of pre-
serving animals, practised by Mr. Waterton. This
article occurs in the Cornhill Magazine, January, 1863.
It tells what has to be done, but not how to do it.
" The tools required hardly deserve the name, for all
these wonderful effects are produced with a penknife,
a lump of wax, half-a-dozen needles, and three or four
wooden skewers. In simple fact, the modus agendi
is pure modelling, the skin being used as the material,
and reduced by art to the plastic state of sculptor's
clay, a temporary stuffing being placed within it
to keep the skin moderately distended during the pro-
gress of its drying." I should be very glad if some
one among the many readers of Science-Gossip
would give better the directions, or name some work
where they may be found. — JV. L. Beaumont.
Rose-coloured Pastor is not the shelah, a
thrush, nor ever will be. It is a starling, and closely
allied to our well-known birds. It is a visitor to all
parts of the United Kingdom. There is a most
interesting account of its visiting and breeding in Italy,
in the "Zoologist" for last January. See also
Harting's "Handbook of British Birds."— C. H.
Bree, M.D.
The Opercula of Shells. — Among those who
take an interest in the science of Conchology there
are many who almost leave out of sight the opercula
or lids by which the mouths of many shells are
closed. They ought, however, to be noticed,
because, according to Gray, the typical form of a
shell-fish is the bivalve ; and he considers the oper-
culum but as a variation of the other valve. There
seems to be some reason for this, because, as we all
know, in many bivalves, as in the Oyster, the smaller
valve takes very much the place of it ; and in that
curious shell, the Anomia, it seems hardly needed,
and — one step further — in the Limpet it is altogether
wanting. There is a curious provision of nature in
those cases of Univalves in which this lid is wanting ;
they secrete in very dry weather, and in the winter,
what is called an epiphragm, or thin membrane, which
covers the opening as a substitute for the operculum.
An example of this is to be seen in the common
garden snail {Helix aspersa). The variety of form
among the opercula is very remarkable. In the case
of Cyclostoma elegans, our only land-shell having this
lid, it is nearly circular ; that of Turbo Sarmatictis
has a coralline appearance on the upper side, or, as
Woodward calls it, like some of the tufaceous
deposits of petrifying wells. Some again are very
thin and brittle, as in the Whelk {Buecinum undatum),
and not at all the same shape as the former, but
brown and horny, and in shape an ellipse. — S.
Cream - coloured Blackbird. — A cream-
coloured Blackbird was shot in Easingwold church-
yard some time in March. It is a very fine specimen,
and in very good condition. I may also mention
that a cream-coloured mouse was trapped in a house in
this city on the 7th. They are both in the possession
of Mr. Ripley, Bird-skiffer, Feasegate, York. — Percy
Thompson, York.
Poisonous Properties of the Fluid of the
"Solanum Dulcamara." — To my certain know-
ledge, the berries of this plant are injurious to chil-
dren. I have seen more than one instance of very
serious effects having followed the eating of "dead
men's cherries," as the fruit of the bitter-sweet or
woody nightshade is often called, — effects which
would probably have ended sadly had not prompt
measures been taken. The children had fortunately
in each case eaten sufficient to produce sickness, and
this was aided by emetics until all the berries were
dislodged. One little fellow had slight convulsions
for days, therefore, I have not the slightest doubt on
the subject, though Majendie and others state that
they would not hesitate to take them, because they
are innocuous to animals. "Seeing is believing."
The twigs and leaves of the Solanum Dulcamara
possess medicinal properties. — H. G. Watney.
" Sorrel, from the Low German snur, sour."
NOTICES TO CORRESPONDENTS.
To Correspondents and Exchangers. — As we now
publish Science-Gossip a week earlier than heretofore, wo
cannot possibly insert in the following number any communi-
cations which reach us later than the gth of the previous
month.
R. G. — Thanks for the slide. The mounted arachniae taken
from the legs of the House-fly appears to be a species of
Ganiasns, allied to the Beetle-mite (G. Coleopti-atorum, L.),
but another species.
W. H. N. — Your bald-headed sparrow had, perhaps, been
in the " wars," a not uncommon occurrence ; or it had been
affected too considerably by mites.
M. H. Robson (Newcastle-on-Tyne). — The box containing
glass tube in which you enclosed a variety of Hydra, reached
us with the glass smashed to pieces. It should have been
posted with a luggage-label attached, on which the address and
stamp should have been placed. The blow given when stamps
ing had shattered the glass.
M. J. Wilde. — Your specimens are : — (1) a piece of Trap,
with calcite crystals on joint-face ; (2) fragment of Copper ore
(Cupric sulphite) ; (3) piece of Milk-quartz ; and (4) portion of
water-worn nodule of Flint.
F. Norris. — The plant you sent us is a fine specimen of the
Blue Fleabane (Etigervn acris).
Anonymous. — We are obliged to call attention to an old
rule of ours, which declares that anonymous communications
cannot be attended to.
R. G. C. — The insect found on the dog is a well-developed
specimen of the Dog-tick {Ixodes ricinus). We cannot under-
take to answer your latter question without fuller information.
Newquay. — The grass you inclose is the Annual Meadow
Grass (Poa annua), and the other species intermingled with It
is the common Spurrey (Spergula arvensis, L.J.
2l6
HARDWICKE'S SCIENCE-GOSSIP.
F. L. St. A. (Hants).— The shrub labelled No. i is a Buck-
thorn {Rhamnus Frangula, L.), and the other specimen is very
imperfect, and too small to judge correctly ; but we believe it
to be Calamintha Nepeta. Many thanks for your kind note
respecting orchids.
B. M. W. (Treaddow). — We detected only one rust, or clus-
ter, at the margin of one of the leaves, which is undoubtedly
Trichobasis Geranii, B., but we believe it is attacked by an-
other fungus unknown to us ; but it is immature, therefore
difficult to decide in its present state.
G. A. H. (Manchester). — It is what we have recognised as
Chara hispida; however, we confess they are too little studied,
and very little seems to be known about this class of plants.
C. H. Bould. — Your plant is the Soap-wort (Saponaria
officinalis).
W. H. Legge. — We have forwarded your account of "a
strange bird " to several first-rate ornithologists for identification,
but all, without exception, state they cannot make anything out
of it.
G. S. Barnes. — See an account of your peculiar malfor-
mation of cabbage-leaf in present number.
E. E. Evans. — Your eggs were completely smashed when
they reached us, so that it was impossible to name any of them.
W. E. Richardson. — We have received the Trilobite, which
is a fine specimen of Calymene Blumenbachii. What you took
to be a "fin" is merely the rim of the cephalic shield. The
Trilobites being Crustaceans (allied to King-crabs) did not
possess " fins."
R. H. N. Browne. — The eggs grouped on the backs of oak-
leaves are not those of Coccus, but of a species at Aphis. Two
of them hatched whilst the leaf was under the microscope, so
that the aphides were visible.
A. Lury (Southampton). — The white substance you sent us
from the bark of a young Scotch fir is not a fungus, although
it was formerly considered, and even described, as such, under
the name of Psilonia nivea. It is of animal origin, however,
like the "Apple-blight," and formed by an insect, a species of
Cynips.
E. C. — From your specimens we can only make out the
male and female of the common gnat (Culex pipiens) ; except
that they are smaller specimens than usual under the micro-
scope, they exhibit all the characters of the common gnat.
S.— -It is Mr. Lankester's "Wild Flowers worth Notice " to
which we referred.
F. R. S. — Prof. Hull has already published a work on the
Geology of Ireland, and another and a fuller work on the
same subject by Mr. G. H. Kinahan is about to be published.
See papers called " Sketches in the West of Ireland," by Mr.
Kinahan, in Science-Gossip for 1873, 1874. and 1876, giving
archaeology, botany, and geology of the district.
J. Cass. — A potato tuber is only an underground bud ; and
the monstrosity you sent us is not an unfrequent one, as it con-
sists of pseudo-tubers, or buds, forming at the base of the leaf-
stalks. We have seen several examples this summer.
J. A. Floyd. — The specimens sent us from Cambridgeshire
are of Lower Cretaceous age, but, perhaps, not sueh excellent
phosphates as the so-called " coprolite " stones, on account of
their containing a large percentage of iron oxide. No. 1 are
the teeth of Spherodus. 2. Tooth of Saurian, probably Cam-
py/osaurus. 3. Ammonites lautus. 4. Tooth of Saurian.
The others are fragments of fossil wood, impressions of A mmo-
nites, casts of chambers of A mmonites, &c.

QUARTZ^ AS IT OCCURS IN THE LAKE DISTRICT;
ITS STRUCTURE AND ITS HISTORY,
By J. CLIFTON WARD, F.G.S., F.R.M.S., &c.
{Read at the Annual Meeting of the Cumberland Association for the Advancement 0/ Literature and Science.)
INTRODUCTION.
HERE are few minerals
more widely spread than
Quartz, a chemical com-
pound of the two ele-
ments, Silicon and Oxy-
gen. Common though
this mineral is, however,
its study opens out
questions of deep inte-
rest, and may lead us
from the contemplation
of a pretty piece of rock-crystal to the consideration
of subtle and hidden processes in the formation of the
crust of our globe.
1. Geological Distribution. — Quartz occurs among
cur lake-country mountains in several forms, but
never as a rock by itself, in thick-bedded masses, as is
occasionally the case in other mountain tracts.
Vein Quartz exists under four conditions.
(1.) Constituting the whole thickness of a lode or
vein, in which case the latter may be said to be a
quartz vein, unless the quartz contains much valu-
able ore, such as lead or copper, for then it will
more frequently be called a lead or copper vein
with a quartz veinstone. Some of these quartz
veins are of considerable width — many yards, — and
run in straight lines, sometimes for several miles,
though often broken by faults. That they contain
gold in small quantities is certain, and I have in my
possession some small grains of this precious metal
extracted from a vein of quartz in Borrowdale. It is
well known that gold has been mined in Wales for a
great many centuries, but it seems not to exist in any
of our Cumberland quartz veins in workable quanti-
ties, so far as I have been able to judge.
(2. ) Instead of being itself a lode or vein, quartz
frequently forms strings or courses running in or
through a lode formed of various mineral substances .
No. 166.
Supposing the lode to be lead-bearing, it often be-
comes an important question how much of the vein-
stone may be quartz, and how much calc-spar, barytes,
or other minerals ; for the quartz is very much harder
than most other constituents of veins, and if the ore
has to be extracted entirely from such a matrix, the
labour is much increased. Nevertheless, sometime1-,
even quartzose vein-stuff is quite crumbling, and,
when so, the working is comparatively easy. This
is the case with several lead-veins occurring in the
Vale of Newlands.
(3.) Quartz, when occurring either as a massive
lode or a slender string, is opaque, and generally of a
pure white colour ; but it occurs, thirdly, in the form
of clear transparent crystals, lining the sides of cracks
and fissures either in massive quartz or in some other
mineral substance. These crystals have the general
form of a six-sided prism, terminated by a six-sided
pyramid, but owing to variations in the relative size
of the several faces, the appearance of the crystals
may vary. Sometimes also they are coloured in
various tints, clue to oxides of iron, manganese, &c,
mingled with the oxide of silicon, or silica, as it is
more usually called. It will be noticed that the
pointed ends of the crystals project away from the
sides of the crack or fissure which they line.
(4.) Lastly, vein quartz occurs in indefinite
lenticular masses and strings among the strata of many
geological formations. Thus, occasionally it may be
seen to occur between the planes of bedding of strati-
fied rocks, more frequently, however, traversing those
planes in an irregular and stringy manner, and some-
times much developed along the cleavage planes, as
may be seen in the Skiddaw Slate between the sum-
mit of Hindscarth and Scope End.
Quartz as a Rock-constituent : —
[a.) Of Stratified Rocks.
(b.) Of Unstratified Rocks and Volcanic Rocks.

In the Skiddaw Slates there are many parts,
L

especially the lower, seen on Whiteside and Gras- '
moor, which have been produced by sandy or gritty
■deposits, and the grains of quartz may frequently be
distinguished clearly with the naked eye. Again, in
a well-marked bed of grit, in the upper part of the
Skiddaw series, to be well studied in Great Cockup,
north of Skiddaw, in the sides of the southern breast
of Skiddaw, and notably at Lank Rigg and Latter-
barrow, in the south-west of the Lake District, the
grains of quartz frequently approach the size of small
pebbles. In all these cases the quartz fragments are
more or less rounded, showing that they have been
rolled in the water, and are formed of white quartz,
such as occurs in veins, or such as may be won from
the disintegration of granite. Even in the clay-slate
proper, the microscope reveals the presence of small j
grains of quartz amongst the aluminous matter.
In some of the beds of Carboniferous Limestone
that wrap round the mountainous tract, quartz occurs
both in the form of small pebbles and of curious
amorphous masses, very similar to the flint in chalk,
but known as chert. In the sandstones, interstratified
with the limestone, quartz, in more or less rounded
grains, is the chief constituent. In the Penrith sand-
stone, of younger age than the Carboniferous, the
small grains of quartz are specially interesting,
because, in some parts of the sandstone, at any rate,
each grain shows the form of a doubly-pyramidal
crystal, the crystals being of very uniform size, and
their form often not a great deal affected by rolling.
Whence these little crystalline particles could have
been derived, to form the sandstone, is somewhat of
a puzzle. Among the Blue Mountains of New South
Wales, Darwin observed a similar case, and remarks :
" It is difficult to imagine how these crystals can have
been formed ; one can hardly believe that they were
separately precipitated in their present crystallized state.
Is it possible that rounded grains of quartz may have
been acted on by a fluid corroding their surfaces and
depositing on them fresh silica ? " The silica in old
glass sometimes regains its crystalline structure, as
shown by Sir David Brewster in 1840.
Quartz as a Constituent of Unstratified and
Volcanic Rocks.
( 1 . ) Among Granitic and Granitoid Rocks. — Gene-
rally speaking, in true granites, quartz occurs uncrys-
tallized, being the last of the constituent minerals to
solidify ; it then appears to fill up all the interstices
of the other minerals, the felspar and the mica. This
is the case with the Skiddaw, Eskdale, and Shap
granites in the mass ; though sometimes very locally,
or in the form of dykes proceeding from the main
mass, the disposition of the quartz is not interstitial,
but crystalline. This latter mode of occurrence may
be well studied in the quartz felsite of St. John, and
notably in the Armboth Dyke. In these cases the
quartz and some of the felspar have crystallized out
in a felsitic base, and the cross sections of the quartz
crystals often look nearly square from the unequal
development of all the six sides. In the Armboth
Quartz Felsite Dyke, the embedded crystals are most
clearly seen, and the pyramidal termination of both

( Greenstones). — I know of no cases of quartz occurring
in a crystalline condition in the rocks of the Green-
stone class. Nor is quartz generally a conspicuous
constituent in any form among such rocks. Micro-
scopic study of the class, however, reveals the very
frequent existence of this mineral in small portions
among the other constituent minerals. In some cases
its presence may be due to deposition subsequent to
the first formation of the rock, and such belong to
our next group.
(3.) Quartz as an Accidental Constituent. — -By an
accidental constituent is meant one that forms no
essential part of the rock, but has been introduced,
perhaps, long after that rock was formed or solidified.
Its manner of occurrence in these cases clearly shows
that the quartz has been deposited from solution, —
water containing silica infiltrating through the rock-
mass. It thus fills up cavities, and sometimes replaces
other minerals dissolved away.
Among the volcanic rocks of the district, quartz is
very common in this form. In beds of lava, and
sometimes in those of volcanic ash, vesicles or long
almond-shaped cavities are generally produced by the
escape of vapour and gases from the molten or heated
matter, on its first eruption from the volcano. Subse-
quently, when such lava-beds have been covered up
by great thicknesses of overlying strata, the water,
which is for ever percolating the crust of our earth,
and contains very various mineral substances dissolved
in it, deposits these in the cavities and vesicles, and
amongst other minerals thus left to fill the vacant
spaces quartz is very common, and may often be
found filling the same vesicle with the minerals
calcite (carbonate of lime) and chlorite. When a
large vesicle has been thus filled with quartz, vari-
ously coloured and under different physical forms, it
sometimes happens that the surrounding rock is
subsequently broken up and destroyed, and then the
hard kernels of quartz are isolated in the form of
agates. Such are the agates of Wallow Crag,
Keswick.

sufficiently well marked to admit of the species of
this section being also subdivided.
a. Villicaides proper; type, R. Umbrosus (Macro-
phyllus, var., of some authors). — The stems of
this bramble when old, are frequently apparently
glabrous, from the hairs being deciduous ; the young
shoots and flowering branches are, however, always
shaggy with spreading pubescence ; the leaflets
round with a short acumen, moderately thick,
smooth, and dull green above, pale and furnished
with short hairs beneath ; prickles strong, conical,
patent ; panicle pyramidal, with ascending branches ;
not unfrequent in copses and shady places : Pinner
woods, Putney Heath, Broxbourne woods. R.
villicaulis. — Stems and general habit similar to the
preceding ; leaflets thick, obovate, or broadly oval,
often cuneiform below ; obtuse or mucronate ; patently
dentated, green above, whitish and velvety beneath
veins of the upper leaflets often reddish ; panicle
compact above, more open below, with ascending
branches ; petals white, obovate, not contiguous ;
sepals ovate, with a mucronate point, setose and
aciculate ; prickles moderately strong and straight ;
rachis and pedicels frequently remarkably velvety :
Broxbourne and Wormley woods. R. macrophylhts. —
The leaves in this species are large, broadly obovate,
thin ; panicle elongated, with ascending branches.
It is a variable plant, and occurs in the woods about
Broxbourne, or intermediate, with the following
species : — R. leucostachys may be easily recognized
by its close-set panicles of pink flowers, with fila-
ments of a still pinker hue ; the petals are large,
obovate, and contiguous ; the stems angular and
hairy; leaves soft, dull green, hairy above, and more
so beneath, of a roundish or obovate form ; those of
the upper part of the young stem and of the flowering
branches whitish beneath, the rachis is whitish, with
a soft tomentum, as are also the pedicels ; the calyx
is rather dark, hairy, setose, and aciculated. — N. B.
In common with all brambles of this subsection, a
few seta; are sparsely scattered on the rachis, &c.
b. Tomentosi. — In this group the spreading hairs
of the stem, and especially of the rachis, appear in
the altered form of adpressed stellate down ; type
R. discolor. This is the bramble of general occur-
rence in wayside hedges ; it is so well known that,
except to indicate the chief points in which it differs
from others, it is hardly worth while to refer to it.
The stem is angular and armed with strong, usually
recurved prickles ; hoary when young from the stel-
late down ; leaflets quinate below, ternate above ;
narrowly obovate, small (usually) coriaceous, slightly
convex, dull green above, white or grey below, with
a close-set felt or tomentum ; rachis, pedicels, and
calyx felted in the same manner ; panicle narrow,
with short branches ; petals contiguous, obovate,
pink ; styles more or less deeply tinged with purple,
as are also, not unfrequently, entirely or in part, the
filaments. R, tkyrsoideus : less common, but by no
means rare. The stems are as stout and strongly
angled as are those of R. discolor, but the stellate
down is less closely adpressed ; the leaflets are
broader and more acuminate upwards, larger, and
not convex ; the under-side similarly felted ; rachis
and calyx both hairy and felted ; panicle long, nar-
row ; lower branches many, axillary ; petals white.
R. rubeolas (Sallcri) .— This bramble is the connecting
link between the Villicaules and the Nitidi. The
stems in this species are nearly terete, reddish ; hairs
scattered and deciduous ; prickles rather strong,
declining, straight, not curved ; leaflets obovate, or
lanceolately acuminate, grey and slightly pubescent
below ; rachis loosely pubescent ; panicle narrowly
thyrsoid and prickly ; petals pale rose, obovate ;.
contiguous sepals, hairy, aciculate, obovate. It
flowers early : gravelly commons, — Barnes, Putney
Heath.
V. Nitidi. — Stems thorny, strongly angled, en-
tirely free from hairs, acicula;, and setae ; but the
rachis of the panicle is hairy more or less : type, R.
rhamnifolius {cordifolius ?). Arched stems of a lively
red colour, angled, and furnished with strong prickles,
straight and deflected, sometimes patent ; leaves
quinate, of a bright green colour, lighter below,
ovate, the terminal one cordate, acuminate, or sub-
cuspidate ; the basal ones narrowly ovate and
strongly directed backwards, finely serrated ; petals-
white or faintly tinged with pink, obovate ; styles
green. Copses and on the borders of woods, not
often in hedges : Hampstead Heath, Putney Heath,
Harrow Weald Common. On Barnes Common and
elsewhere there is a variety with smaller and more
coriaceous leaves ; terminal leaflet not cordate ; a
smaller and more compact panicle and smaller flowers
of a pale blush colour. This is certainly R. rhamni-
folius proper ; R. Lindleyanus (/iMrfus) differs from
both in the form of its inflorescence, which is corym-
bose somewhat, with short patent branches below, and
not pyramidal. It has shining bright red stems ; shin-
ing light-green leaves, whitish underneath, narrower
than those of R. rhamnifolius, and coarsely and
doubly toothed ; petals pure white ; filaments turning
crimson as the flowers fade. It occurs on Harrow
Weald Common and Stanmore Heath. R. incurvatus*
— This bramble, uncommon elsewhere, is plentiful
on Putney Heath and on Barnes Common ; there are
also a few bushes on the lower part of Hampstead
Heath. The stems are green, reddish when old,,
smooth, angled, and furnished like its congeners with
rather strong prickles, which are patent on the
stems, but decurved on the rachis ; the leaflets dark-
green and glabrous above and below, deeply and
sharply toothed, concave, the margins incurved and
wavy ; the panicle is narrow, branches short and
patent ; petals white, obovate ; sepals ovate, hairy,
greenish. (The peculiarity of the leaves is not seen
when they are pressed and dried. )

of the London Rubi. Probably other species and
varieties are known to observers ; we have several
doubtful specimens ourselves, which would, if really
out of the common, warrant the inference that much
may be done in this field of research. Altogether,
the subject is not a very satisfactory one ; but some
practical gain would result from a determination of
the extent to which certain deviations from the cha-
racteristics of a definite number of typical forms
occur under certain conditions of locality, and
whether they are constant in such conditions. The

the tomentosi ; but we could do so only in a general
sense, because the exception; in every case would be
too frequent. Specific nomenclature, therefore, de-
rived from the form of the leaflets, should be dis-
carded.""" The down and pubescence of the stems,
on the other hand, are often deciduous : true, these
characteristics are frequently apparently wanting,
but the lens applied to that portion of a stem which
has not been exposed too directly to the sun or vicis-
situdes of temperature will often reveal its presence

characteristic distinctions of the sections above de-
tailed are deduced entirely from the stems ; no reli-
ance can be placed upon those derived entirely from
the leaves, still less from the form of the panicle.
This may be racemose, corymbose, pyramidal, or

In September the blackberries are ripe, the right
time for gathering specimens as well as fruit ; the

are angled, and rarely elsewhere ; their bases are often glan-
dular or hairy as well as the stem itself.

noted and remembered, in order, when July comes
round again, to obtain the flowers. Sometimes in a
brake three or four species of bramble will be found
growing together, their branches intertangled : care
must be taken in such cases, when making cuttings,
to avoid mistakes ; flowering branches should always
be taken with sections of the old stem attached, and
in making sections of the new stem it should always
be so done as to include a leaf. Notes also
should be entered in a memorandum-book relative
to soil and locality ; habit of growth ; colour of
the leaves, on the upper as well as under-surface ;
shape and colour of the petals ; colour of the styles,
filaments, stems, &c, — points which cannot be de-
termined from dried specimens. Good localities for
research arc the borders of copses in open upland
situations, bushy places in old chalk and gravel pits,
shady unfrequented lanes, swampy woods, gravelly
commons, and the bushy borders of sandy and peaty
heaths.
ON A "TANGLE" DREDGE.
By H. C. C. M.
HAVING spent my holidays for several years
past in shore-collecting on the North Welsh
coast with considerable success, T determined this
further communications on the subject before having
a dredge made. In the following number of Science •
Gossip Mr. E. Lovett, of Croydon, recommends a
dredge of hemp "tangles " as being superior in some
respects to the ordinary form. Not clearly under-
standing how Mr. Lovett would construct his dredge,
I wrote to him for further particulars, and the con-
struction of the dredge, which I will now attempt to
describe, is the result of several suggestions made in
his courteous reply. My thanks are also due to
David Keid, Esq., of Oldham-street, Manchester, for
one or two valuable hints. A, fig. 185, is a piece of
brass wire, about the thickness of a lead pencil, and
16 inches long, each end of which is firmly soldered
into a boat-shaped piece of lead, BB, 4 inches in
length. Lengthwise through each piece of lead a
piece of brass wire, CC, about half the thickness of
A, and 10 inches long, is fastened, with the ends
bent round in the form of a ring. D is a V-shaped
piece of brass wire of the same thickness as CC, the
two arms of which are each 15 inches long, and the
ends are firmly hooked to the rings of CC. To this
the towing line is tied. EE are bundles of rope
4 feet long, the strands of which are untwisted, and
the fibres pulled out, until they resemble bundles of
coarse, rough string. These are firmly tied to the
bar A. Fig. 186 shows the bar A and the boat-shaped

bar is bent upwards, to allow of its passage over large
specimens without injuring them by its weight. Fig.

the boat rowed against the current, and to put it into
the water in the proper position, allowing it to fall
to the bottom very gradually. Although I did not
get a large number of specimens, my captures included

very fine specimens of O. rosula and 0. neglccta),

polyzoons, mollusca, and Crustacea, not one of which
was injured by the tangles. A pair of scissors
were, I found, very useful in removing the specimens.
I am afraid that with one exception (the channel
between Penmon and Puffin Island) my choice of
localities for dredging was unfortunate. One place,
about half a mile from Beaumaris pier, in the direction
of Puffin Island, was recommended to me by several
fishermen as being likely to repay the trouble of dredg-
ing, but I was much disappointed with the results of my
efforts. However, I feel quite certain that the tangle-
dredge will prove to be a useful implement in the
hands of marine zoologists, and I shall be glad if
some of the readers of Science-Gossip will try it,
and record their experience. Manchester.
CANADIAN NATURAL HISTORY NOTES.
I SAW in last October number of Science-
Gossip, an advertisement offering specimens of
the notorious Doryphora decem-lineata for sale at
one shilling each. We pay for specimens also, but
we pay a few cents a pint, or so much a hundred,
for them.
I also read, in a recent English newspaper, a re-
port of the mulcting of a labouring man, the fine
being likewise, if I remember aright, a shilling, for
having a living specimen of that beetle of evil
reputation in his possession. If such a law as that
brought to bear upon the unhappy rustic were in
existence here, it would superadd a large amount to
our revenue, inasmuch as few of us are able to dis-
possess ourselves of such specimens.
It is not, however, my intention, in troubling you
with this communication, to treat, at any length, on
the Colorado Potato-beetle, for your September
number (1877) contains an interesting article on the
natural history of that garden pest from Mr. Rye,
amply sufficient for your purpose at the present time.
I say at the present time, for if the insect reaches
your shores in any numbers, and if it breeds thereon,
you may be glad of hints from those of us who have
been overrun by this unconquerable enemy, and who
have spent nights in an attempt to devise some plan
for its extermination, and days in an endeavour to
carry out such plan if regarded as at all feasible.
The beetle is commonly called the Potato-beetle,
but it by no means follows that that all-important
esculent is alone subject to its attacks. I think it
will be found that, under certain circumstances, it is
omnivorous, and that, at all events, it will not succumb
to starvation even where potatoes are not grown,
provided other vegetables are at hand.
For instance, where the egg-plant, Solatium melon-
gena, is cultivated, my experience induces the belief
that the beetle prefers this plant even to the Solatium
tuberosum. It also attacks, although less ravenously,
tomato and pepper plants, and, somewhat singularly,
the latter in preference to the former. Inasmuch
however, as these three plants are grown only on a
small scale, hand-picking, the most effectual method
of removing all insect-pests, can be resorted to ; and
therefore the beetles do not, as in the case of potatoes,
at the period of hybernation, burrow in their neigh-
bourhood, and, as a further necessary consequence,
do not emerge therefrom in the spring.
Where hand-picking, from the large space to be
traversed, is impracticable, Paris green is the only
panacea ; the powder being mixed with water in a
pail and sprinkled over the plants by means of a
whisk.
There is, however, a principle of compensation
pervading nature, which has a tendency to check
the ravages of noxious insects. Thus, with the
advent of the Potato-beetles into Canada, there
appeared, attendant upon their flight, large quantities
of lady-birds, the Coccinella novemnotata, and others,
with the object of preying on their eggs. And it
should be noted, lest friends and foes be involved in
simultaneous destruction, that the eggs of these two
insects are very similar in appearance, being much
the same in size and shape, of the same colour
(deep orange), and deposited alike on the under-sides
of the leaves of the plants on which the insects feed.
And now we are told of another enemy of the dreaded
beetle, — the Lydella doryphora, — to which allusion
was recently made at a meeting of the Toronto
Entomological Society, by its president, Mr. Brodie,
in the following terms: — "It is by far the most
reliable and valuable of all the enemies of D. decem-
lineata ."
When the Colorado Beetles make their unwelcome
appearance in England — far distant be the day ! — I
would recommend the enactment of a law for the
preservation of rooks ; for, if I mistake not, those
Corvi will be found most useful coadjutors to children
in a potato-patch. These beetles are seen more
frequently on the wing in the day-time than any other
Coleoptera I am acquainted with, and present a some-
what brilliant appearance in their flight.
It may hap that the English climate will prove too
damp, and the soil, in winter, too moist for their
comfortable hybernation, but these conditions should
not altogether be relied on : they will be upon you in
time, just as the Scotch thistles have become an
"institution" in the United States, and the English
Cabbage Butterfly, Pieris rapiv, has become accli-
matized in Canada.
By the way, par parenthlse, while alluding to mi-
grations, I noticed a communication from A. Wyles,
p. 188, respecting some eggs he "obtained in the
village of Roundhay, near Leeds," and which he
supposes to be those of the Red-winged Starling.
He describes the eggs as being of "a greenish grey,
streaked with deep yellowish brown." I have none
of these eggs by me at present, but Wilson informs
HARD WICKE 'S SCIENCE- G OS SIP.
us that they are " of a very pale light blue, marked
with faint tinges of light purple, and long straggling
lines and dashes of black." The Stitrnus predatorius
is very common with us, and up our lakes hundreds
of them may be seen of an evening on the rush-
beds, just as I have seen the common starlings in
England, where I have killed a dozen or more at a
shot.
While submitting my notes on the parasites of the
Colorado Beetle, it occurs to me that perhaps a few
more instances of the principle of compensation may
not prove uninteresting.
We have in Canada a great variety of Ichneumon-
flies, from the large Pimpla lanator, with its four-
inch borer, to the Ichneumon minntiis, each in its
own peculiar way, whether by piercing the living
insect, or its egg, doing its providential work in the
destruction of hurtful life.
Some time ago my eye was attracted by the eccen-
tric motions of one of the larger steel-blue Ichneumons
that was flying round and round a currant-bush in
my garden, ever and anon darting at an object which,
on approaching it, I found to be a spider in her web.
The contest, for such it was, was a long one, and
put me in mind of the description of an arena-fight
between a retiarins and a sccutor. The latter, on
this occasion, was victorious : the rete proved an in-
sufficient protection, and the fuscina, or ovipositor,
was thrust into the victim's body, with what result is
well known to naturalists.
On another occasion I saw one of our larger grass-
hoppers, Locusta Carolina, struggling in apparent
agony and certain helplessness on the ground. On
examination I discovered a small ichneumon, not
much larger than a winged ant, upon its body, intent
on the insertion of its ovipositor, and although the
fly was so much smaller and so much weaker than
the unhappy grasshopper, the latter was unable to
make use of its powerful legs or its wide expanse of
wings as a means of escape.
Another singular parasite, if parasite it may be
called, is the Hair Worm, Gonlins. I once obtained
two of these Abranchiata from the body of a large
spider — a somewhat uncommon habitat. These
worms were tightly rolled up into small balls of the
Gordian-knot type, and were, when unfolded, only
about two inches each in length.
At another time I found one of our common
crickets, the Acheta abbreviata, with a Hair Worm
curled around it. Whenever the miserable insect
made an effort to release itself from the coils of its
tormentor the latter lashed itself into apparent fury,
and seemed to paralyze its victim until at length it
accomplished its horrible design.
Are these egg-depositing operations painful to the
subject ? It would be interesting if observers would
state their opinions, and give us the results of their
observations, on this interesting subject.

SOME REMARKS ON HORSE-TAILS.
THE Horse-Tails compose the order Equisetaccce,
and this order of Cryptogams is a very inte-
resting one, both as regards the structure of the plants
contained in it, and the curious hygrometric move-
ments of their spores.
The stem is underground, and in the spring sends
up branches, some of which are barren, while others
bear the spores. The branches are hollow, except at
the joints, which are numerous ; at these points the
different segments of the stem are separated by a
sort of cellular membrane. Each joint likewise
terminates in a sheath, which is membraneous, and
embraces the base of the succeeding joint. The
branches are fluted, and the sheath at its upper
extremity is cut into teeth, the number of which
corresponds, or bears some simple proportion, to the
flutings on the stem.
These plants are devoid of true leaves ; but the
latter are represented by branchlets, which are of a
green colour, and often assume a verticillate arrange-
ment. A very interesting microscopical object is
furnished by the cuticle of the Horse-Tail — the sto-
mata being seen with great clearness under a mode-
rate power. The epidermis is likewise peculiar, on
account of the large quantity of silex which it con-
tains ; this is so abundant in many species that they
have been used by the Dutch housewives for polishing
brass.
The most interesting points, however, about these
plants is their fructification. All the branches are
not fertile, but those that are bear at the terminal
extremity a cone-like body, which, on examination,
is found to consist of a great number of disks, more
or less polygonal in outline, borne in a peltate
manner upon a central stalk, by which they are
attached to the central axis. On the under surface
of these disks the spore-cases are arranged, and these
discharge their contents (the spores) by a lateral slit,
which looks towards the axis of the plant. The
spores themselves are more or less rounded bodies,
each provided with two filaments called elaters, and
to the contraction and expansion of these the move-
ments of the spores are due. The elaters end in
club-shaped extremities. If the end of a branch of
Equisetum bearing fructification be shaken gently on
to a glass slide, and the latter be then breathed upon,
and placed upon the stage of a microscope of low
power, the spores will be seen to be undergoing the
most curious movements. Some will be quite closed
up, the elaters being so closely applied to the spores
as to be scarcely distinguishable ; others, again, will
be seen gradually unfolding the filaments, and a few
may be observed to move with a sudden start, as it
were, from the contracted state of the elaters to that
of full expansion. The ultimate cause of this move-
ment is quite unknown. That it depends upon the
224
HARD WICKE 'S S CIENCE - G OS SI P.
amount of moisture with which the spores are sur-
rounded there can be no doubt. Most probably it
takes place by the contraction and expansion of the
cells of which the elaters are composed, under the
varying influence of the moisture contained in the air.
The phenomenon is a very curious one, and should
by all means be seen by every one who possesses a
microscope.

Doubtless the spores are endowed with this suscep-
tibility to hygrometric changes in order to ensure
their distribution, and thus the species is continued
in distant places. The spore on germination gives
origin to a cellular structure called a prothallus, upon
which the antheridia and archegonia are borne —
much as in Ferns. In former periods of the world's
history the Equisetacese occupied a much more pro-
minent situation in the vegetable kingdom than they
do at present. If we turn to the Palaeozoic strata we
shall find in the Carboniferous formation of that
period abundant evidence of this. The reed-like
fossil Calamites most likely belonged to this order,
and the vegetation of the Carboniferous period is
made up of the genera Lepidodendron, Stigmaria,
Sigillaria, &c, belonging to the Lycopodiacea?, Equi-
setacere, and allied orders.
This order also affords an instance of what has
been called homoplasmy, or likeness between plants
belonging to totally different orders, and even different
divisions of the vegetable kingdom. Thus the Equi-

setacerc of the acrogenous sub-kingdom has its coun-
terpart in the Hippurus, or Mare's - Tail, which
belongs to the division of flowering plants.
It is often the case that botanical collectors give
a great deal of attention to the Ferns and Mosses,
and treat with comparative neglect the humble Cryp-
togams, including the Equisetacea;. This neglect
seems to be unmerited ; for, although the flowering
plants, doubtless, at first sight, form a more attractive
field for the display of the energies of the popular
botanist, yet any one who will take the trouble to
work at the Equisetacea; and allied orders, with lens
and microscope, will find, in the adaptation of means

to ends and delicacy of structure, quite as beautiful

NATURAL HISTORY IN THE
SEVENTEENTH CENTURY.
F. Kitton, Hon. F.R.McS.
IN the eighth volume of Science-Gossip we called
the attention of our readers to the Bestiary of
Philip de Thaun, written in the twelfth century, during
the long period that had elapsed between the publication
of that treatise and the work I now propose to give
some extracts from, we might expect to find a consi-
derable advance in Zoological knowledge. Such,
however, is not the fact, not the slightest attempt
seems to have been made to verify the descriptions of
the early writers, and their accounts of monsters are
implicitly believed in.

Bestiary, as the following verbatim copy of the title-

which the writer thinks will tend to make mankind

Wren doth fight with an Eagle contending for
soueraignty ? Would it not make men to reverence a
good king set over them by God ? Seeing the bees
seek out their king if he loose himself, and by a most
sagacious smelling sence never cease untill he be
found out, and then beare him upon their bodies if he
be not able to fly, but if he die all forsake him. And
what king is not united to clemency and dehorted
from tyranny, seeing the king of the bees hath a sting
but never useth the same ? . . . . I have followed
D. Gesner as neer as I could, I do professe him my
author in most of my stories, yet I have gathered vp
that which he let fal, and added many pictures and
stories as may apeare by conference of both together.
In the names of the beasts I have not swarved from
him at all. He was a Protestant Physitian (a rare
thing to find any Religion in a Physitian) although
Saint Luke a Physitian were a writer of the
Gospell — Your Chaplaine in the Church of
Saint Buttolphe, Aldergate, Edward Topsell."
In the "Epistle to the Learned ReaJas'' he
gives "the Catalogue of the Authors which have
wrote of Beasts," viz., Hebrew, Greek, Latin, Ger-
man, Italian, French, and the following English
writers, Edward Wooton, William Turner, M.D.,
John Estwyck, John Falconer, M.D., Thomas
Bonham, M.D. Thomas Gybson, M. D.
The Rev. E. Topsell adopts a very simple arrange-
ment, viz., an alphabetical one, thus avoiding all the
troubles of orders, families, and genera. The first
animal he describes is the Antelope. "The Antalope
called in Latin Calopus, and of the Grecians
Analopos or Aptolos. Of this beast there is no
mention made among the auncient writers except
Suidas and the Epistle of Alexander to Aristotle,
interpreted by Cornelius Nepolius. The vertues of
this beast are vnknowne, and therefore Suidas saith
an Antalope is but good in part."
The woodcut represents the animal with slightly
curved horns conspicuously serrated on the upper
margins and a long tooth in the lower jaw.
The next beast described, according to the author's
arrangement, is the Ape, of which he remarks that it
"is held for subtell, ironical, rediculous, and un-
profitable beast, whose flesh is not good for meate
as a sheep, neither his backe for burthern as an asses,
nor yet commodious to keep house like a dog, but
of the Graecians termed Gelotopioon, made for
laughter.
And as the body of an Ape is ridiculous by reason
of an indecent likeness and imitation of man, so is his
soul or spirit ; for they are kept only in riche men's
houses to sport withall, being for that cause easily
tamed, following every action he seeth done, even to
his owne harm, without discretion."
The female, the writer tells us, "mostly has twins,
whereof they loue the one and hate the other ; that
which they loue they beare in their armes, the other
hangs at the dam's back, and for the most part she
killeth that which she loueth by pressing it to hard r
afterwards she setteth her whole delight upon the
other.
The male and female abide with the young one,
and if it want anything, the male, with fist and irefull
aspect, punisheth the female. When the moone is in
the waine they are heauy and sorrowful, but they
leap and rejoice at the change, for, as other beasts,
so do these feare the defect of the starres and planets.
They are full of desimmulations and imitation of
man ; they readiler folow the euile then the good
they see.
They loue conies very tenderly, for in England an
old ape (scarse able to goe) did defend conies from
the weasell, as Sir Thomas Moore reported. They
feare a shel-fish and a snaile very greatly, as appear-
eth by this history.
In Rome, a certaine boy put a snaile in his hat and
came to an Ape, who, as he was accustomed, leaps
upon his shoulder and took off his hat to kil lise in
his head, but, espying the snaile, it was a wonder to
see with what hast the Ape leaped from the boyes'
shoulder and in a trembling manner looked backe to
see if the snaile followed him.
A Lyon ruleth the beasts of the earth, and a
Dolphin the beasts of the sea. When the Dolphin is
in age and sicknes, she recovers by eating a sea-ape j
and so the Lyon by eating an ape of the earth, and
therefore, the Egyptians paint a Lyon eating an Ape
to signify a sicke man curing himself. The hart of
an ape, sod and dried, whereof the weight of a groat
drunk in a draught of stale Hunny sod in water,
called Mellicraion, strengthened the heart, embolden-
eth and driveth away the pulse and pusillanimity
thereof, sharpeneth ones understanding, and is
soueraigne against the falling euill."
The following is a list of Apes described by
Topsell : — Vulgar ape, monkey ape, marline ape,
callitriche ape, Persian ape, baboun ape, Tartarine ape,
satyre ape, monster ape, Norwegian ape, pan ape,
sphinx ape, Sagon ape, ape called beare ape, ape
called foxe ape. Figures are given of these forms.
We need scarcely say that they were in the majority
of cases evolved from the artist's inner conscious-
ness. As a specimen, we give a copy of the head of
the Sphingu or Sphinx ape. Of this species the writer
gives the following description: — "The Sphinx, or
Sphiiiga, is of the kind of Apes hauing his body
rough like Apes, but his breast, up to his necke, pilde
(bald) and smooth without hayre : the face very
round, yet sharp and picked, hauing the breasts of a
woman, and their fauor or visage much like them."
To the utter confusion of the anti-Darwinites, we
quote the following from the history of a Satyre ape,
clearly showing the existence of an intermediate form.
Topsell's authority for this is unimpeachable, for he
says: — " S. Ierom, in the life of Paul the Eremite,
reporteth there appeared to S. Antony an Hippo-
centaurc, such as the poets describe, and presently he

saw in a rocky valley, adjoining, a litle man hauing
croked nostrils, homes growing out of his forhed,
and the neather part of his body had goat's feet : the
holy man, not dismayed, taking the shield of faith
and the breast-plate of righteousnesse, like a good
souldior of Christ, preased toward him, which
brought him some fruites of palmes as pledges of his
peace, upon which he fed in the iourney, which same
Antony perceiving, he asked him who he was, and
received this answer : I am a mortall creature, one of
the inhabitants of this desart, whome the Gentiles
(deceued with error) doe worship and call Fauni,
Satyres, and Incubi. I am come in ambassage from
our flock, intreating that thou wouldst pray for vs
unto the common God who came to saue the world :
the which words were no sooner ended but he ran
away as fast as any foule could fly. And least this
should seame false, vnder Conslantine, at Alexandria,
there was such a man to be seene aliue, and was a
publike spectacle to all the world, the carcase
whereof, after his death, was kept from corruption by
heat through salt, and was carried to Antiochia that
the Emperor himself might see it."
" Satyres are very seldome seene, and taken with
great difficulty, as is before saide, for there were two
founde in the woods of Saxony, towards Dacra, in a
desart, the female whereof was killed by the darts of
the hunters and the biting of dogs ; but the male was
taken alive, being in the vpper parts like a man, and
in the neather parts like a goat, but all hairy through-
out : he was brought to be tame, and learned to go
vpright, and also to speak some wordes, but with a
voice like a goat, and of this kind there are store in
Ethiopia."
" Of the Asse. — Asses are of very foolish condicions
and slender capacity, but yet very tame, not refusing
any manner of burthen although it break his back.
Ammonianum was in such love with an asse, and
holding him of so great capacity, that he had one
continually to heare his lectures in Phylosophie.
Callen affermeth that an ass understandeth, genus
species et individuum ; because, if you shew him a
camell that never saw one before, he is terrified and
cannot endure his sight ; but if he have been accus-
tomed to such a sight, if you shew him never so
many he is not moved at them. In like sort hee
knoweth men in general, being not affraid of them ;
but if he see or heare his keeper he knoweth him for
his keeper or maister.
The asse being overcome with melancholy humour
naturally looketh for the hearbe Citterach, or Finger-
feme, to cure him. The asse is neuer at peace with
the cro, because he longeth for the asse'seyes ; likewise
the bird Salem, for when the asse commeth to the
thornes to rub himselfe where the same bird buildeth
her nest, the asse spoyleth it, wherefore the said bird
maketh continual assault vppon him. In like sort
the Colota, or Stellio, for it sleepeth in the mangers,
and creepeth up unto the asse's nose to hinder him
from eating. The woolfe is also an enemy to the
asse, for he loveth his flesh, and with small force
doeth he compasse the destruction of an asse ; for
the blockish asse when he seeth a woolfe layeth his
head on his side that so he might not see, thinking
that because he seeth not the woolfe the woolfe can-
not see him ; but the woolfe vpon this advantage
setteth vppon the beast on the blind side and easily
destroyeth the courageless asse.
Another argument of an asse's stupidity is that he
careth not for his own life, but will with quietnesse
starve if meal be not laid before him. Wherefore it
is apparent that when a dull scholler not apt to
learne is bid to sell an asse to signifie his blockishnes,
is no vaine sentence ; therefore they which resemble
asses in their head, round forehead, or great face,
are said to be blockish ; in their fleshy face, fear-
full ; in broad or great eies, simple, and like to be
mad ; in thick lips and the vpper hanging over the
nether, fooles ; and in their voyce contumelius and
disdainfull. . . . The Ieiaish people, who like asses,
could not understand the evident truth of Christ in
the plaine text of Scripture, wherefore our Saviour
secretly vpbraided their dulnes when he rode upon
an asse.
Touching such medicinall vermes as have been
tried and found to be in the several parts of asses in
learned and approved writers, now in this history
they shall be briefly remembred, and so this narration
finished."
These remedies would occupy more space than the
editor would grant me, an example must therefore
suffice. "If any be hurt by the starres wash them in
asses stale mingled with Spiknard, the same force has
it against comes and all hardness or thicknesse of
skinne."
" Of the Indian Asses. — It is questionable whether
the Monoceros, commonly called a Vnicorne, the
Rhinoceros, the Oryx, and the Indian asse be one
beast, or diuers ; for the Vnicorne and Rhinoceros
haue the same things attribvted to them in stories,
and differ in verie few reports, both Aristotle, Pliny,
and ^Ehanus coyntly agree that they differ from
all other whole-footed beasts, because they haue one
home in the forehead, and so have also the Rhinoceros,
Monoceros, and Orix, but the Indians cal a Vnicorne
Cartagono ; and the home so highly prized at this day
is thought to be of the Rhinoceros, but ^Ehanus and
Philes acknowledge no other Vnicorne, but the Indian
Asse, who in bignes equalleth a horse among the
Indians, being all white on the body, but purple-
headed or red (as some say), black eyes, but Volatter-
ranus saith blew, hauing one home in the forehead,
a cubit-and-a-halfe long, whose upper part is red or
bay, the middle black, and the neather part white,
wherein the kings and mighty men of India vse to
drink, adorning it for that purpose with sundry
bracelets, precious stones, and works of gold holding
for truth that all those which drinken in those homes

shall be freed from annoyance of incurable diseases,
as conuulsions, the falling euile and deadly poi-
sions."
We find two other species of asses described in this
veracious history, viz. , the Alborach and Axis ; the
former is, the author says, "the animal whereupon the
Turkish priestes and blasphemous idolaters perswade
the silly pilgrims of Media that Mahomet was
carried up to heaven."
Of the Badger, otherwise called a Brocke, a Gray,
or a Bauson. — The Rev. E. Topsell most unkindly
exposes the ignorance of this animal ; he commences
his description by saying, " The Badger could neuer
find aGreeke name. The Italians call a Badger Tasso ;
the Rhetians, Tasch ; the French, Tausson, Taixen,
Tasso//, Tesson, and sometimes Grisart (for her colour),
sometimes Blareau (now Bla/rea/i), and at Parris
Bedo/io ; the Spaniardes, Tasugo, Texon; the Ger-
mans, Tachs, orDaxs; the Illyrians, Gezweez. Badgers
are plentiful in Naples, Sicilly, Lucano, and in the
Alpine and Heluitian coasts ; so are they also in
England. In Italy and Germany they eate grayes
flesh, and boil it with peares, which maketh the flesh
tast like the flesh of a Porcupine. The flesh is best
in September, if it be fat."

AN EDITOR'S HOLIDAY IN THE WEST
OF IRELAND.
ONE of the most bewilderingly lovely drives or
walks in the West of Ireland is that from
Westport to Cliefden. The distance is something over
forty miles, and the road is tolerably good, although in
many places chequered by acclivities and declivities.
If walking, we should recommend the pedestrian to do
the first eighteen miles to Leenane, which is, in our
opinion, the most beautiful spot we visited. The road
thereto lies over the mountains, and, after gradually as-
cending three or four miles from Westport, we traverse
the surface of a table-land, everywhere boggy and wet,
and with pretty loughs or lakes studding its surface.
Some of these loughs are very paradises of water-
plants, and their margins are covered with the cool
green leaves and exquisite white blossoms of the
common water-lily. All round this table-land there
rises a panorama of hills. Some of them may be
called mountains, for they are three thousand feet in
height, and their tops stretch upwards into the sky,
so that the cloud scenery is mapped and patterned by
their presence, and presents quite a different appear-
ance to cloud-land in our own parts of the country.
They have a riven and a weird look, these ancient
hills, for they are composed of the very hardest rocks
known to geologists— namely, the metamorphic rocks.
The Silurian sandstones and slates and limestones, most
of which once contained fossil remains, have been so
completely altered by heat that scarcely a trace now
remains of a fossil, and yet their geological map
— for this country has been geologically surveyed
by some of our ablest men — shows the whole region
in a variously coloured pattern which indicates how
different is the variety of rocks. The white lines on
the map, which represent faults or vertical crackings
and slippings of the solid rock, are exceedingly
numerous. Along the line of some of these faults
the valleys now extend, for they have proved the
weak places where weathering action could be best
exerted. The outlines of these grand old hills
have been sculptured by Father Time. They are
amongst the oldest of our British mountains, and no
country in the world has such ancient mountains as
Great Britain and Ireland ! For millions of years
the storms of different climates have gathered around
these ancient peaks, and have spent their fury upon
them not in vain, for it is chiefly to the combined
and continued action of the weather that their very
shapes are now due.
Fig. 196. Terraced Limestone Hills, Glen Colombkill.
From the table-land we have mentioned, a peaty
stream called the Erive makes its appearance, at
first so small that a boy could jump across it easily.
As we pass along the uneven road, the stream
gathers strength from its numerous tributaries, all of
them after a rainy night seaming the sides of hills
like silver threads ; and anon it gains in violence and
volume and brawls over its rocky bed, which latter
widens as well as deepens as the stream descends to-
wards the sea. Here and there it throws its volume
of seething water over some rocky terrace as a water-
fall or cataract, and occasionally its restlessness seems
to be checked by some deep pool which the brown,
peaty-coloured water causes to appear of unfathom-
able depth. Everywhere, however, along the route
of the stream, even in these elevated regions, there was
growing such a wild luxuriance of that most magni-
ficent of all British and even exotic ferns— the Royal
Flowering fern (Osmunda regalis) — as we have-
never before seen, except perhaps once along the
HARD WICKE'S SCIENCE- G OSSIP.

southern side of Barton Broad, in Norfolk. The
tall fronds rise to a height of five and six feet, with
their brown spore-bearing branches rustling to and
fro in the mountain wind. As we passed along the
road we saw numbers of ordinary marsh plants, but
we were on the outlook for one particular flower
which occurs nowhere else in the British Islands,
except these western coasts of Ireland. It is
one of the heaths, known as St. Dabeoc's (named
after an Irish saint), and formerly christened by
botanists Dabeocia polifolia, although now, in honour
of a Scotchman, its generic name has been unmu-
sically changed to that of Mcuzicsia. By and by we
came in view of this lovely heath. Great was our
joy, for we had never seen it before except in the
pages of Sowerby. The reader may well pardon the
delight of an ardent botanist at the first sight of this
plant, growing in luxuriance in its wild abodes, for
its beauty is not exceeded even by the magnificent
heaths which have been imported into our green-
the primitive village and capital inn of Leenane is
situated. No better spot for the tourist to rest a few
days could be selected than this. Along one moun-
tain pass he can proceed to Kylemore Lough, which
is, perhaps, the loveliest in Ireland, with the excep-
tion of one of the lakes of Killarney, for Kylemore
Lough has not only rugged and bare mountains rising
around it on every hand, but these are softened down
near the margin of the lake by rounded bosses,
festooned with honeysuckle, and bramble, and wild
rose, the haunt of a thousand plants dear to the
botanist, and now bright with three or four species of
heath, including an abundance of our prized Dabeocia.
Shrubberies of hazel bush, willows, alder, and larch
come down to the very edge of the water, while
above them stand stately groups of Scotch fir, whose
rough stems gather 'all the light that is in the sky
and reflect it in the very warmest of colours. Rarely
have we been more pleased with a situation than that
of Kylemore. At one end stands the magnificent

houses from the Cape of Good Hope and Australia.
Its rose-coloured, bell-like flowers are about three
times the size of those of our English heaths, which
latter grow side by side with it, as if for the sake of
comparison.
After some miles of tramping, the pedestrian will
discover that he has passed the highest point of the
water-shed, for the streams are now flowing in a
different direction. The mountain scenery becomes
grander as he proceeds, the mountains appearing to
present themselves one after another like the billows
of a stormy sea. At length a glimmer of light
appears between the hills where the valley ought to
be, and we gradually approach Killery Bay. This
is a fiord like Clew Bay, extending from the sea
sinuously into this mountain land for a distance of
twelve or fifteen miles, the mountains rising in some
places quite steeply from the water. Various moun-
tain streams pour themselves into it at the head where
seat of Mr. Mitchell-Henry, M.P. for Galway, who
has done good work in the neighbourhood by in-
ducing the peasantry on his estate to drain the bog
lands, so that they are being rapidly^converted into
fertile fields.
From Leenane there are beautiful roads to Delphi,
through Glen Fee, and to the Pass of Saal Ruck, a
walk of about six or seven miles after having crossed
Killery Bay. The bay is full of fish, especially
mackerel and whiting, and this delicate food can be
obtained in almost unlimited quantity. From Leenane
to Cliefden is about twenty-four miles, and Kylemore
Lough may be taken on the road. Towards Letter-
frack we were particularly struck by the signs the
landscape presents of the influence which moving
ice has exerted in this region. During all our
journeyings we had been beset by the strongest evi-
dence of this kind, but nowhere is it more plainly
seen than at Letterfrack. Husre hillocks of refuse
230
HARD WICKE'S SCIENCE- G OS SIP.
are composed of fragments of rocks of almost eveiy
size of bigness and smallness, each fragment polished
and scratched by the ancient ice-sheet which long ago
disappeared. Low rounded bosses of rock, called
roches moutonnk, had been seen on each side of the
road all the way from Westport, many of the latter
covered with scorings and strice, all of them con-
verging in the direction of the valleys. There can
be little question that, before these bays or fiords were
filled with salt water, they had been filled with ice,
and had very probably been deepened by the mechani-
cal erosion of the moving ice-sheets towards those
deeper and lower parts now covered by the waters of
the Atlantic.
Near Letterfrack we came upon some limestones
which had been altered by heat until they assumed
the appearance of loaf-sugar. Some of the lime-
stones have been coloured green, and the well-known
"green marbles" of Connemaraare obtained from this
deposit. Of them many exquisite ornaments are
manufactured and sold at Clifden, the deposit crop-
ping out along the hillsides. A grander country for
the geologist, and especially for the physical geologist,
could hardly be selected than this, for there are so
many varieties of rock formations, particularly of the
older and more primitive rocks, that at every few
hundred yards the student comes upon a new stratum
on which he feels forced to exercise his hammering
abilities. Perhaps none of them struck us more than
the outcrop of what had once been a Lower Silurian
conglomerate, that is to say, a shingle or gravel bed,
which had accumulated as such in one of the earliest
geological periods. The pebbles of this bed were
formed of various kinds of granite, and they had been
cemented together in a sandy and clayeykind of matrix,
until the entire stratum had become solid. Then this
bed had been exposed to the influence of heat and the
enormous pressure of overlying masses, so that both
the pebbles and the material in which they had been
imbedded had been metamorphosed together. No
more instructive illustration of the great changes
effected upon the configuration of the earth's surface
by the agency of heat could have been afforded. The
only drawback to the geologist whilst studying these
rocks is the absence of a donkey-cart and a good
strong donkey, for his knapsack soon gets full and his
pockets weighed down, and, worst of all, he is
obliged to leave specimens behind him that he would
otherwise gladly carry away to gloat over and study
during the winter months.
We reached Cliefden late in the evening, when the
dusk was falling around us, and the neighbouring
hills were gradually shading off into immaterial
obscurity. We rose early next morning in order
to catch the eight o'clock mail-car for Galway.
Punctually to the moment, a lumbering old car, with
two Irish horses harnessed thereto, made its appear-
ance at the hotel door, an Irishman perched as
if lie were on the top of a chimney-pot in front of the
machine. The first part of our way led us by the
side of the well-known and much-talked-of Twelve
Pins or Bens, both the word "Pin" and "Ben"
(which is common in Scotland) meaning head or peak
in the Celtic language. The names, in this instance,
have reference to a group of twelve tall mountains
which stand clustered together in the wildest part of
Connemara. The road to Galway winds in and out
of the valleys formed by and along the base of the
mountains, so that we had magnificent mountain
scenery on the left-hand side, whilst, on the right,
there extend, for miles, a series of lakes like "pearls
on a string. " Some of these lakes, as, for instance,
Lough Inagh and Glenda Lough, are of considerable
size, and have islands in their midst upon which are
the ruins of many an old castle or keep. At Ballyna-
hinch, in one of the largest of these islands, we
behold one of the finest of these castles, that of
the Martins, an Irish family which once possessed
almost regal power in this part of the country, and
owned no fewer than 200,000 acres of land. At
Recess there is a capital hotel, much frequented by
salmon and trout fishers, their prey being abundant
in the lakes and rivers of the neighbourhood. Here,
too, the scenery becomes more wooded ; but the drive
from Recess to a village called Oughterard is one of
the wildest and most dismal that it is possible to
imagine. We saw it under characteristic conditions.
There was a drizzling rain descending from the
mountain clouds all the way, and it seemed to bring
out the misery and the sloppiness and the bogginess
of the low grounds in all their intensity.
As we approach Galway the country becomes more
cultivated. The roadsides and walls are perfect para-
dises of ferns, among which Scolopendrium vidgare,
Asplenium trichomanes, and Ceierach officinarum,
are most abundant. There are signs of greater
wealth, and here and there mansions make their
appearance with rich woods around them. Lake
Corrib stretches away to the very heart of the Twelve
Pins, some forty miles away, and a steamer plies
up and down the water during the summer months.
At Galway bridge we could see from the parapets
the salmon in scores, three or four thick, lying at the
bottom of the stream, waiting for the freshets, so that
they could pass up the salmon leap and through the
loughs into the mountain streams above. A day or
two may be agreeably spent in Galway, especially in
exploring that outlying suburb called the " Claddagh,"
where the Spanish settlers of 300 years ago still live
apart from their Irish brethren, with a mayor of
their own, elected every seven years, and governed
by their own unwritten laws (which are obeyed
much more strictly than the written laws of the Saxon
in Galway town).
We left Galway by the steamer which crosses the
bay to Ballyvaughan. The day was intensely hot,
and the atmosphere seemed full of light. Hence the
white limestone-terraced hills of the Burren would

have been unbearable for one's eye to gaze upon had
it not been for the oases of greenery here and there.
We think there can be little doubt that these rock-
terraces are due to weathering, and that they do not
represent successive sea-beaches, as some imagine.
The terraces appear to coincide with the outcrop of
the limestone beds, and the terraces are most pro-
nounced towards the tops of the hills, the debris
lying along the bases having greatly protected the
lower strata from meteorological erosion. The rain-
fall hereabout is 54 inches in a year, and as it mostly
descends in a fine drizzle, nearly every drop must tell
upon the limestone, and its weathering action must
therefore be almost complete.
We stayed a few clays at Lisdoonvarna, a pleasant
green country, richly undulated, where the
Yoredale shales abut against the Carboniferous
limestones, and the water percolating through the
former dissolves away its iron pyrites, so as thus to
form "Spas" of notable benefit. Dr. Westropp, the
kind and genial physician of the place, has made a
remarkable living collection of all the varieties of the
Hart's-tongue ferns found growing in the fissures and
joints of the Carboniferous limestone near Black-
head. These joints are very numerous, and in each of
them we saw growing a wonderful luxuriance of
Maiden-hair (A. capittus-veneris} and other ferns ;
while on the cliffs the surface was matted with Dryas
octopetala (still in flower) ; and patches of Statice
spathitlata grew here and there, close by denser tufts of
Aspleniiini marinum. Near Mohr Cliffs we found
Lastrea recurva completely covering a bank for a
short distance. These Cliffs are a magnificent
spectacle, rising quite perpendicularly for nearly 600
feet out of the sea. They are formed of Lower
Carboniferous rocks, the thin flagstones of which
are completely covered with worm or molluscan
tracks. We should be delighted to convey to our
readers even a faint idea of the pleasure we enjoyed
from the detailed exploration of the limestone rock-
gardens, surely unknown the whole world else-
where, and of the loveliness of the green western
Irish land, and of its balmy atmosphere, which one
can almost taste !
The Carboniferous limestone underlies the whole
country hereabout — a land bare, almost as a wooden
table, of grass, and yet richly feeding numbers of
sheep. The real reason why sheep are able to feed
over the limestone tract of the Burren hills, is that
the rocks are so much fissured with the vertical
cracks, in which grow the loveliest of wild plants,
many of them rare to the botanist, and a profusion
of such ferns as the Hart's-tongue, the Maiden-hair
{Adiantum capilhis-veneris), the Ceterach, and many
others. Various species of grass also grow in these
chinks, and it is upon the latter that the sheep
browse, and so the spectator is presented with the
peculiar appearance of sheep grazing on what appears
to be a region of the poorest and the baldest rock.
MICROSCOPY,
" New Forms of Animal Life ! ! " [vide Times
report of Sir W. C. Thompson's paper on the official
report of the Challejiger Expedition, August 21,
1878).—" Sir W. Thompson says that Mr. Holdich is
illustrating most of the pelagic genera, these plates re-
presenting several remarkable forms of 'shizopods/
to which they have given the name of Challengerida,
as they seem to have hitherto escaped observation.
Professor Hatchel is about to publish a splendid
memoir of the Radiolari. Any one acquainted with
Hatchel's classical work, ' Die Radiolariem,' would
have some idea of what may be expected of that
memoir. Mr. Moseby is at work on a most remark-
able little series of coralloid forms of the Hydrogor,
which he has named Hydrocorotmal, and on their
strictures and relations Mr. Moseby's careful work,
during the voyage and since their return [query, of
the Hydrocorotmal '], had thrown quite an un-
expected light. Professor Hatchel would describe
the medusce. The Peliatozo would be described by
himself (Sir W. Thompson). About twenty plates
were cut stone (these will make a heavy book)
illustrating the stalked crinoids. Professor Alexan-
drac Ligussis was going on rapidly/with the Echiniden.
Mr. Lyman was working at the Opherxides, and he
expected Mr. Phere, of Upsala, to come over to ex-
amine the Holtheridea, which he was going to describe
under the general superintendence of Professor
Lowe." A friend says I am mistaken, these are not new
names, and if the following corrections are made it
will be all right. For shizopod read rhizopod, Radio-
lariem read Radiolarien, for Hydrogor read Hydrozoa
(I still adhere to it that Hydrocorotmal is new),
Opherxides is the same as OpIiiitridcF, and HoltJuridce
is identical with Holoihuridce, and Professor Hatchel
is vulgarly known as Haeckel. — F. K.
Highbury Microscopical Society. — We are
pleased to state that a Highbury Microscopical So-
ciety has just been formed under the presidency of
Dr. Alabone. Applications for membership should
be addressed to the hon. secretary, Mr. R. B. Brind-
ley, 37, Highbury Park, N. The opening meeting
of the society will take place on Thursday, October
10th, at Harecourt Hall, St. Paul's Road, High-
bury, with an exhibition of objects of a scientific
nature, principally shown by the microscope.
Tickets free on application.
Measuring with the Microscope. — A very
simple arrangement for measuring microscopic ob-
jects has been invented by Mr. G. J. Burch, and
fully described in the "Transactions of the Quekett
Club," for July, 1878. It is as follows :— The body
of the microscope is placed in a vertical position,
and one of the forms of " Beales's " Neutral Tint
Camera Lucida, placed as usual over the eyepiece,
attached to the tube of the Camera, and at right

angles to it is a light rod, 'of any convenient
length, upon which a graduated scale slides opposite
to the thin glass in the Camera. On looking through
the latter the object will appear to have the scale
laid upon it, and its size can be easily determined.
The rod upon which the scale is clamped should be
graduated in order that the magnifying power of the
objective may be ascertained and registered : this is
ascertained in the following manner : — the divisions
on the scale are adjusted to those seen on the stage
micrometer, and its position noted for future reference.
It is necessary the figures on the scale should be
reversed. A goniometer scale for the measurement of
angles can be easily substituted for the ordinary scale.
The Miniature Microscope Lamp. -We have
recently tried the above-mentioned lamp, just intro-
duced by Messrs. How & Co., St. Bride-street,
Ludgate Circus, London, and find that, although very
much smaller than those hitherto
in use, it affords a pure white
light sufficient for all micro-
scopic purposes. One of the
advantages of its small size is
the much less heat given off, a
somewhat important matter,
when a dozen or more lamps
are burning simultaneously. It
is fitted with the Improved
"Hailes" shade; this in its
original form, as most of our
readers are aware, was that of
a porcelain cylinder, with an
aperture at the lower part, the
rest of the light being obscured ;
it was supported by a brass ring
sliding on the upright rod of
the lamp. One fault in this
form of shade was that a great
amount of light was visible
above it, and generally on a
level with the eye of the ob-
server. In the new shade this
has been obviated by the upper
part being made dome-shaped, the eyes being thus
effectually protected from glare. The shade is sup-
ported by a "gallery" just below the burner; it
is therefore always in position. The lamp, when
not in use, is packed in a japanned tin case, about
3 inches in diameter, and 9 inches in height, and
weighs under two pounds.
The Painted Lady. — Have you ever observed
a kind of metallic sound when this insect is on the
wing? I also fancy it has a partiality for sandy
patches on hedge-banks, especially under the shade
of trees. It flies later in the evening than some other
species, and is a bold insect — returning to the spot
where an attempt has been made to capture it.

ZOOLOGY.
The Black-Throated Stonechat in Lanca-
shire (Saxicola stapazina). — It is a pleasing duty
to me to record the taking of a very beautiful
specimen of what I consider an exceedingly rare bird
in our neighbourhood {Saxicola stapazina). The
specimen was shot by a friend of mine about the
middle of May this year on the margin of the Bury
and Radcliffe Reservoir ; and, though very mangled
with shot, having a goodly number of 6's, it has been
very well mounted indeed by my friend Johnson, of
Prestwich. Considering the condition it was in from
being killed with such large shot, I really doubted at
one time whether it could be mounted ; however, it
has been, and a valuable addition to our list of birds
it is. We naturally ask ourselves now, if this bird
is no native what is it doing here, and how came
it to visit us? The most probable solution to this is,
the Stonechat family are migratory, leaving us for
more southern and western countries about the begin-
ning or middle of September, returning to us in large
flocks about the end of April or beginning of May ; and
likely enough this specimen, being of the same habits
as our Wheatear, has travelled along with a flock
and reached our shores, whence he would drive
inland in search of a mate. I have sought many works
on British birds, but failed to find its mention ; and
the only description I can find is in Cassell's "Book
of Birds," vol. ii., p. 199. The bird I have is
a male bird, in fine mature plumage, and in very
good condition when shot. Its habits when alive,
as noticed by several parties for a few days prior
to its being captured, were very active, vigilant, and
shy. It seemed to hoid itself aloof from any of
the same order (Saxicola cenanthe). Cassell's de-
scription of these birds in their native home is very
interesting, and I here give an extract : — "Though
they by no means avoid fruitful tracts or cultivated
districts, these birds very decidedly prefer to take up
their abode in mountainous or stony regions ; and
are for this reason particularly numerous in Sweden,
Southern Germany, and Switzerland ; in the latter
country they are popularly known as Mountain Night-
ingales, from the height to which they often ascend.
Even the icy and rugged tracts of Scandinavia and
Lapland seem to suit their requirements, and we have
often seen them hopping nimbly over the glaciers in
situations where no other living objects were dis-
cernible. Individuals inhabiting more southern lati-
tudes display the same liking for barren grounds, and
are usually seen in localities so sterile and arid as to
appear totally incapable of affording them a sufficient
supply of the insects upon which they subsist ; their
disposition is lively, restless, and very unsocial ; only
during their winter migrations do they seem to com-
mingle with others of their species, even when cir-
cumstances compel a certain amount of neighbourship ;
each bird lives for itself, without appearing to have
HARD WICKE'S SCIENCE- G OSS IP.
233
the slightest interest in the proceedings of others in the
vicinity." In order to more clearly identify this spe-
cimen from our Wheatear {Saxicola cenantke), I have
had a male specimen of the latter mounted along with
it, from which it will be seen there is a very wide
difference ; the colours of S. stapazina are, on the
head, nape, and back, white, slightly tinged with
rust yellow ; on the belly and breast dulled white ; the
throat and cheeks, from above the eyelids, including
the ear-coverts, are jet black, quite as much or more
than the Pied Wagtail (Motacilla Yarellii) ; the upper
and under tail-coverts are white ; the two outer tail
feathers on each side are white, slightly edged and
tipped with black ; while the three next on each side
are white, slightly edged (but not tipped) with black,
the middle tail feathers are entirely black, the wings
are a beautiful glossy black, as are also the legs and
toes. I did not take the dimensions of the bird when
dead, but it is a trifle smaller than S. iinanthe, as
will be seen on comparison. I have shown the
specimen to several very able naturalists, and not
one remembers having seen the species before. —

Animal Stupidity. — In studying the intellects
of the lower animals it is no less important to note
their mental shortcomings than the cases in which
they reason correctly. Early this year I observed
a singular piece of irrationality on the part of a large
black retriever. The animal lived in the last house
of a "terrace," in one of the northern suburbs of
London, separated from the next terrace by a walled
alley. Finding itself one day locked out, and being
unable to effect an entrance either by the front door
or by a side door leading into the alley, it made its
way into the front garden of the end house of the
next terrace, and made most persevering but fruitless
attempts to leap over the wall. Had it succeeded it
would, of course, only have landed in the alley
which it could enter from the street. After a short
time it left the garden, and ran round into the street
and the alley, but still returned again and again to its
endeavours to jump the wall until its master came
home.— J. IV. Slater.
Cannibalism among Caterpillars. — Receiving
two half-grown larvae of the Goat Moth, I put them
into a tin box and left them for a short time. On re-
opening the box I found that one caterpillar had en-
tirely devoured the other except the hard case of the
head and a portion of the skin and prolegs. At first
sight I thought that the larva; had assumed the chrysalis
state, or had thrown off its skin, but a careful exami-
nation failed to discover the chrysalis, and the box was
too securely fastened to allow of the caterpillar's
escape ; so the conclusion that one larva had devoured
the other was the only one I could satisfactorily come
at.— C. C.
Parasite of the Linnet.— I am induced to
write the few following remarks to Science-Gossip
under the belief that this parasite is not well known.
I shall be glad to hear if any subscriber has a similar
specimen. Figure 199 shows this parasite magnified
50 diameters, and figure 200 shows one foot magnified
280 diameters. It is evidently a P/iysostomnm and
not unlike Physostomum mystax, said by Mr. Denny

to infest the chaffinch. The head is large and
devoid of antennce and trabecular The legs are long,
the femora thick, the first joint of the tarsus has a
pulvellus. The mesothorax is wanting and the
metathorax is continuous with the abdomen, which
consists of 9 segments. The colour of this parasite
is brownish yellow with a dark band down each
side. It can move with great rapidity among the
feathers of its host. — IV. A. Hyslop.
The Colorado Potato-Beetle. — The appear-
ance of the Colorado Beetle at Jaratschervo, in the
district of Schrimm, in the Prussian province of
Posen, has been officially reported.
The Habits of the Field Vole. — At the
British Association Meeting, Sir Walter Elliott
made a few observations on the annual increase
of the common vole {Arz'ieola agrestis) of late years.
In the spring of 1876 they appeared in such numbers
in the hill pasture farms of the Border districts
between England and Scotland, and parts of York-
shire and Wensleydale, as to destroy the grazing
ground on which the sheep depended in spring,
causing serious loss to the fanners by impoverishment
and death of stock. The shepherds destroyed as many
as they could without sensibly diminishing their
numbers, although assisted by birds and beasts of
prey — hawks, buzzards, owls, weasels, foxes, &c. At
the same time that the vole was doing such mischief,
another species {Arvieola arvah's), not known in
234
HARD Wl CKE 'S S CI EN CE-GO SSIP.
England, made its appearance in Hungary, and
attacked the corn-fields, which it had done to a less
degree in two or three previous years, and this year
they had attacked the wheat-fields of Moldavia, as
appears by a late paragraph in the Times newspaper.
Many instances are recorded of great damage being
done by them, both in England and Scotland, by
destroying plantations, of which Mr. Jesse described
a notable instance in New Forest and Dean Forest
some time ago. These examples prove that they do
not confine their attacks to pastures and woods, and
it is possible that they might, under favourable circum-
stances, betake themselves to our corn-fields. It is
therefore worth consideration whether our game-
preservers should not be more forbearing towards the
hawks, owls, and weasels, which are nearly extermi-
nated in many places, although they live almost entirely
on these and other small creatures. Sir Walter
inquired whether anything similar had been seen in
Ireland ; also whether, as moles and hedgehogs were
the natural enemies of the vole, they should not be
spared ; and with reference to a statement in " Bell's
Histoiy of British Quadrupeds " (last edition) that the
hedgehog was not found in Ireland, whether this was
really the case ? Several speakers said that the hedge-
hog was very plentiful in all parts of Ireland.
Dr. Scl.vter on Specific Names. — In answer
to Robin Goodfellow, in Science-Gossip, p. 189, I
would observe, that it is a great error to suppose that
specific names must necessarily be adjectives. In
many cases they are substantives, and may then be of
a different gender from the generic name, e.g. Turdiis
merula, and Cervus damn. This is the case with
the now scientific name of the common robin,
which has puzzled R. G.'s little boy, and which is
correctly written Erithacus rubecula, rubecula being
a substantive like Erithacus, and standing in appo-
sition with it. In the same way Linnceus called the
Kestrel Falco Tiniutnculus, the Bell Falcon, from
its bell-like cry. But a recent systematist, under the
same misapprehension as R. G., has proposed to
alter Tinnunculus into Tiununada ( !) because the
genus to which he referred it, Cerchneis, is feminine.
— P. L. Sdater.
The Earth-worm. — Professor Paley has added a
great many interesting facts to the little-known habits
of the earth-worm, but he has not exhausted the
subject, and I shall only be too glad if I can add
an item to what has been recorded. After some
very wet days in the month of last June, I spent
several hours in the dusk of evening carefully
noting their actions, my great object being to discover
by what means earth-worms dragged leaves, string,
twigs, &c, along the ground into their holes. I
knew, for I had often seen them clasp objects by
their prehensile heads, twining their finely-pointed
heads firmly round the object, and so draw it towards
their hole, but I had reason to suspect that this, No. 1,
was their ordinary but not their only method. Very
carefully and quietly placing a candle on the earth
where a number of large worms were foraging round
their holes, I look care to place decayed leaves, Sic,
within the radius of the circle swept by their opera-
tions. The objects placed within their reach were,
however, too much the colour of the soil accurately
and distinctly to be sure of the modus operandi, the
thought suddenly occurred to me to try white paper.
Tearing up little strips about three inches long, I
gave them a single fold, and placed one within the
reach of a foraging worm. Very soon its elongated
head came in contact with the paper, and instead of
twining its head round the paper I saw it put its head
underneath. Carefully watching, I saw a lip on each
side of the paper, which being compressed between
the two, the paper was held firmly as in a vice, and
so dragged to its hole. Continuing the experiments
with my paper bait, I saw distinctly that the worm
can compress and almost flatten its head as easily as
it can elongate it. When the head is rendered obtuse,
it can extend it on each side of the mouth so as to
form two large distinct lips, between which it took
hold of the papers and dragged them to the hole ; but
this is only method No. 2. There is yet another,
which at first I could scarcely understand. Observing
a worm place its head under the white paper, so that
its operation was invisible, I saw the paper, without
any apparent means of motion, slowly, ghost-like
moving along the dark ground to the hole of the
worm. Its head was not round it, nor did its lips
enclose any part of the paper, and yet it moved.
Quietly and carefully, by candle-light, continuing for
hours my observations, I saw that when it suited the
creature's purpose best, it had yet a third method of
attaching itself to its baits. The worm having retracted
its head in the same way as when forming its lips,
firmly pressed it for a moment on to the paper, and
then apparently forming a sucker of its mouth, the
paper was firmly attached to it, and so without being
held, except as the leathern toy attaches itself by
exhaustion of air to the stone, the paper followed the
retreating worm and was dragged to its hole. I am
perfectly satisfied as the result of my patient and
tiring watching therefore, that the earth-worm can
secure its object just according to which method best
suits the thing it desires to obtain, either by encircling
a part of it with its prehensile head, by pressing it
between two expansions of the head-like lips, or by
attaching its head and mouth in the way of a sucker.

Notes of Great Tit. — Gilbert White, in his
" Selborne," says the curious notes, resembling the
whetting of a saw, are the early spring song of the

inform me to which of these birds the song belongs ?

BOTANY,
Arum italicum. — This plant is mentioned in
Hooker's "Flora" as occurring in the Isle of
Wight ; but Bentham says the white-veined variety
of A. maculatum from the Isle of Wight is some-
times mistaken for A. italicum. I have a quantity of
tubers of what I believe to be the true variety at the
disposal of those readers of Science-Gossip who
would like to naturalize them, by planting some in
any situation where A. maculatum is established, in
any shady lane or hedge-row, or in their own garden.
I will forward one or more on receipt of stamped
envelope. Larger tubers or extra number will re-
quire two stamps for postage. — Dr. Morton, New
Brompton, Kent.
Mould in Herbaria. — May I suggest a plan
that I have found to answer when a plant that has
been insufficiently dried is attacked by mould. Let
the sheet be taken out of herbarium and placed be-
tween two thick pieces of blotting-paper. Then iron
well with hot iron, changing paper until quite dry.
By that time mould will have entirely disappeared. —

How to Preserve Colours of Dried Plants.
— In the July part (p. 165) a correspondent inquired
for a method of preserving the colour of Primula
vulgaris and Primula elatior for the herbarium. If
the dried plant is painted all over with a mixture of
■one part of nitric acid to about twenty parts of spirits
of wine it will retain its colour. I have a specimen
of each treated in this manner, and though they have
been mounted a long time, both petals and leaves are
of the freshest colour. — Fred. W.E.$.
Flowers of Hollyhock.— On reading what I
wrote about the hollyhock, I perceive an ambiguity,
arising probably from an error on my part in writing.
From seeds proceeding from the same flower, in fact,
I have nine plants, four whose flowers have been
crimson, one light red, one of darker, richer colour,
and one white, which has opened its flowers since I
wrote to you last, besides two plants which have not
flowered yet at all. Of the plants with white flowers,
which came from seeds borne on a branch of the same
parent plant and flowered last year, two have blos-
somed again this year with white flowers as before ;
another, a smaller plant, growing between those two,
had not flowered this year till a few days ago, when I
was startled by the sight of a crimson flower on a plant
whose flowers last year had been white. Here is
variability indeed. — yohn Gibbs.
Verbascum blattaria. — I have found the
Moth Mullein ( Verbascum blattaria) in a waste place,
near Luton, Beds. It was discovered on a hill-side,
above chalk, with flints, by Mr. F. Wiseman, who
brought it to me for identification. That you may be
assured of its authenticity I enclose one blossom.
I would send you more, but after the most careful re-
examination of the locality we can find no other
specimens of it. — y. Saunders.
Botany of Derbyshire. — The Rev. W. H.
Painter desires us to say that he is engaged in editing

Sugar in the Nectar of Flowers.— This was
the subject of a most interesting paper read before
the recent meeting of the British Association, by Mr.
A. S. Wilson, M.A., of Glasgow. Nectar, he said,
is the sweet-tasted fluid secreted within the cups of
flowers, and is intended to provide an inducement to
cause insects to visit the flowers. These insects
confer great benefit on the flowers by assuring their
cross fertilization, bringing pollen from other plants
and depositing it on their stigmas. The result of
this is that the plant is enabled to produce seeds of
much greater vigour than it otherwise would. The
saccharine fluid is usually contained in the most
secluded part of the flower, in order that it may be
protected from rain, for, owing to the solubility and
the diffusibility of sugar, were it not so protected it
would speedily be transferred to parts of the plant
where it could be obtained by the insects without
their serving the plant in the way of cross fertiliza-
tion. The colour, odour, and marking of flowers
enable insects to find the nectar more easily. The
importance of these insects will be apparent from the
smallness of the amounts of sugar found in the flowers
experimented on by Mr. Wilson. Flowers of fuchsia
yielded a total of 7*59 m.m.g. of sugar ; 1*69 of this
was fruit sugar, and 5*9 apparently cane sugar. Of
red clover each head gave a total of 7*93 m.m.g.,
fruit 5 '95' apparent cane sugar 1 "98. On each head
of clover there are nearly 60 distinct florets. Calcu-
lating from these results there was the astonishing
industry of the bee brought out in an extraordinary
manner, for in order to obtain the kilo of sugar
7,500,000 distinct flowers must be sucked. As
honey contained roughly about 75 per cent, of sugar,
a bee has then to make two and a half millions of
visits in order to collect a pound of honey. It was
rather a curious fact that nectar should contain cane
sugar, seeing that honey never did ; indeed, were a
vendor to sell honey containing cane sugar he would
probably be prosecuted under the Adulteration Act.
A change must therefore take place while the sugar
is in the bee's possession — possibly through the action
of the juices with which it comes in contact while in
the honey-bag. As nectar is acid in its reaction it is,
however, possible that the process of inversion may
take place spontaneously.
Proposed Experimental Garden. — Mr. Lax-
ton, Fellow and late Member of the Scientific
Committee of the Royal Horticultural Society,
236
HARDWICKE'S SCIENCE -GOSSIP.
proposes to establish in a central locality and within
easy access of London, an Experimental Garden, for
the purpose of hybridising, cross-breeding, and
selecting fruits, vegetables, flowers, ornamental and
economic plants (chiefly hardy and half-hardy), for
the raising and propagating of useful and choice
novelties, scarce and little known plants of beauty
and utility, and for the trial of new fruits, vegetables,
flowers, &c. It is intended that all experiments shall
as far as practicable be thoroughly and crucially
conducted, and that each experiment with its results,
whether apparently successes or failures shall be
carefully and systematically recorded. The ad-
vancement of Horticulture will be the chief desider-
atum, but scientific and botanical considerations will
be kept in view, and should available means and
space be obtained, the improvement of cereals,
forage, and other agricultural plants will also be
sought. Amongst incidental objects will be that of
testing the adaptability of introduced plants, &c, to
the climate and soil of the district.
GEOLOGY,
The Extinction of the Mammoth. — Mr.
H. H. Howorth read a paper on this subject, in
which he examined the mode in which the Mammoth
had become extinct in Siberia. His conclusion was
that there had been a sudden and violent change
of climate in that country, which had frozen the
previously soft ground, and had also preserved the
Mammoths as in a huge meat safe.
The Pikermi and Sewalik Deposits.— Mr.
W. T. Blandford, F.R.S., has recently published
his reasons for concluding that the above deposits
are of Pliocene, and not of Miocene age, as they have
hitherto been held to be by most geologists. The
nature of the marine shells at the base of the
Pikermi bone-beds attests a Pliocene age. One
mammal (Bos palieimiiais) found in the Upper
Sewalik ^deposits occurs also in the Nerbudda
alluvium, where it is associated with paleolithic
implements. ♦
Carboniferous Amphibia and Fishes. — Mr.
W. H. Baily, F.G.S., Paleontologist to the Irish
Geological Survey, read a paper before the Geolo-
gical Section of the British Association on the
above subject, in which he showed that the remains
of amphibians and fishes were impressed on the true
coal, in a coal-seam, 3 feet thick, at Jarrow colliery,
near Castleconner, county Kilkenny. All the
remains were turned into carbon, one of the fishes
{Megalichthys Hibberti) being over 3 feet in length.
New Species of Star-fish.— Mr. W. PI. Baily
has described a new species of Star-fish from the
Lower Silurian Caradoc beds of county Wexford,
Ireland, under the name of Palasterina Kinahani.
A Permian Fauna in North America. — At
the British Association meeting Prof. Cope described
the remains of a fauna characteristic of the period
which in North America succeeded the Carboniferous.
It occurs in Illinois, and the remains were referred
to Reptilia and Batrachia. In one genus, Clepsydrops,
almost the entire skeleton was discovered. This
was a clawed Lizard, with large canine teeth, and
several incisors.

are so well known and often well authenticated, that
the fact can hardly be doubted. The article by Mr.
Downes in your last number would seem to offer a
good explanation of the phenomena. Any one who
has observed the way in which the so-called " petri-
" fying wells " at Matlock and other places deposit
thick crusts on any articles placed in them, will easily
perceive how the working up of a toad in a rock may
be a question not of years but of months. We must
remember, too, that though the independent testimony
of quarrymen from many places remote from each
other ought not to be set down as mere invention, yet
exaggeration with regard to the thickness or solidity
of the rock is very likely to take place. A short while
ago, however, a curious story was told me about a
toad having been found in the heart of an oak-tree.
The toad was an enormously large one, and the
impression of its body was plainly to be seen. When
I saw the article in your last number, I wrote for
further particulars, and have to-day received a reply-
to the following effect, — that the time was thirty or
forty years ago, that the tree was a large oak in
Pignell Wood in the New Forest, that it was cut in
the spring of the year. The three men who cut the
tree are dead, but my informant, who is getting an
old man, well remembered the circumstances, and, I
believe, was on the spot a short time after the tree
was cut and saw the impression ; at any rate, the
circumstance seems to be well remembered by him.
I give the fact on its own merits, hoping that it may
call forth an answer in explanation or otherwise. —
IV. IV. Fowler, Repton, Burton-on-Trent.
Toads in Rocks. — To those interested in the
subject of the frog and toad living without food,
the following may be interesting : — In the Spring of
1876 I had occasion to go down a well, at Lewisham,
to examine some pumps. Looking round for a place
to put a few tools, I took out a loose brick from' the
side of the well, and, while putting my tools into the
hole, felt something soft and cold, which turned out
to be a frog : it was very thin and weak. I took it
to the surface and carefully put it in a suitable place.
The next day it had breathed its last ; it was nothing
but skin and bone. On making inquiries, I ascer-
tained that during the Spring of 1875, while the
pumps were being repaired, the frog had fallen down
the well, and had been picked up and imprisoned,
thus having been buried forty feet from the surface
about twelve months. Its death, no doubt, was
accelerated by the exertions it made to procure food.
Shortly after this I was at Crayford Water-works,
and mentioning the above circumstance to one of the
turncocks, he told me that about twenty years
previously he had put a toad into the hollow column
of a drilling-machine he was helping to put up at a
works at New Cross. I obtained permission to look

237
into the column of this drill-machine, and there, sure
enough, was the remains of the toad, nothing now
but a few bones and dirt. By its side was the wick
of a tallow candle, but no trace of the tallow was left ;
possibly the toad had eaten the tallow, or, perhaps,
the tallow had decomposed. I should state that the
column was perfectly air-tight, and, as far as I could
learn, had never been opened. It was about four
feet high and seven or eight inches in diameter in-
side. The air inside was foul, as a light would not
burn. Without comment, I leave these two instances
to speak for themselves. — ill. O. Hay don.
The Longevity of Toads. — I have read in
the last number of Science-Gossip, the account,
by Mr. W. Downes, of a live toad having been
found in limestone rock. I believe there are
several well-authenticated instances of that nature,
one of which I now send you. My informant is a
personal friend, and a well-known mining-engineer of
great celebrity. About two years ago, in a Yorkshire
coal-seam 600 yards below the surface, a live toad
was found in the middle of a block of coal. My in-
formant was not present at the moment, but within
half an hour he saw the toad, then dead, and the hole
out of which it came. He had no doubt whatever as
to the truth of the collier's statement that the toad
was in the hole alive at the time he broke the lump
with his pick, and came out apparently unhurt, but
lived only about twenty minutes. I believe my
friend has the toad in his possession. — y. D.

Teratology of Leaves, &c. — I think the en-
closed leaves as curious as the Cabbage-leaf of your
last number of Science-Gossip. We received from
South Africa some seeds of Cobicr. Capensis and some
of Mimosa. We conclude, from the result, that a
seed of each was set in one pot, as two distinct plants,
yet united at the bottom of" the stem, came up, and,
as you see, there is a second freak in the union of the
two plants. Can you tell me if this is only a freak of
nature, or is there a plant that is always so ? — B. H.
Kirby.
Goat Caterpillars. — Can any of the readers of
Science-Gossip say whether there are any means of
saving trees which have become infested by these
caterpillars, and of preventing their spread to others in
the same garden, other than cutting down and de-
stroying the tree? If any know of a remedy, and
would state it, it would greatly oblige, and save some
valuable trees in this neighbourhood. — A. Warner,
Hoddesdon.
Behaviour of Lightning during Thunder-
storms.— A friend and myself were talking of
thunderstorms, apropos of the late ones, when he
spoke of the lightning as having been observed by him
leaving the earth and shooting up towards the sky.
This, I replied, was owing to the position of the
clouds, as electric fluid never left the earth in that
manner during a storm, but might be seen darting
from cloud to cloud. He, however, affirmed that it
did so, and referred me to a work by Captain Snow
Harris for confirmation of what he had seen. He
also said that when trees or buildings were struck the
injury was often done by the electric fluid leaving the
earth, not, as I always supposed, attracted to it, and
that the nature of its track displayed the fact. As I
still doubt whether it be so or no, will you kindly
settle the dispute ?— y. H. G.
Roots of the Palm-Tree. — Two sermons have
been preached lately in our neighbourhood on Psalm
xcii. 12, " The righteous shall flourish like the palm-
tree." In the first sermon special mention was made
of, and a lesson was drawn from, the tap-root which
we were told a palm-tree possessed. The second
preacher, ignorant of the previous sermon, told us
that a palm-tree had no tap-root like most other trees,
and drew a lesson from its absence. " Where doctors
differ disciples disagree." We should be greatly
obliged if any correspondent of Science-Gossip
could tell us whether palm-trees have tap-roots or
not— A. B.
Preserving Animals. — The whole of the
"modus operandi" of Waterton's method, most
exactly described, may be found in the end of his
" Wanderings in America." The early editions of
this work are scarce, but I am happy to say a new
one has lately been issued, price 3/6, and may be
obtained of any bookseller, from the London houses.
W. Bairett-Rowe, Bristol.
Preserving Slugs. — In "Rambles in Search of
Shells," and also in the article on " Land and Fresh-
water Shells" in the "Notes on Collecting and
Preserving Natural History Objects," the following
receipt is given for preserving slugs. " Make a cold
saturated solution of corrosive sublimate ; put it in a
deep wide-mouthed jar or bottle, then take a slug you
wish to preserve and let it crawl on a long slip of card.
When the tentacles are fully expanded, plunge it
suddenly into the solution ; in a few minutes it will
die with the tentacles extended in the most lifelike
manner, so much so, indeed, that if taken out of the
fluid it would be difficult to say whether it were alive
or dead." I have tried this repeatedly, and have
never yet succeeded in obtaining one specimen with
the tentacles extended. In most cases the head of
the slug, when it is dead, protrudes a little outside
the mantle, but there is no sign of a tentacle in any of
them. I should be glad if any of the readers of
Science-Gossip would give me information about
the preservation of slugs, as I am anxious to obtain
them for my collection of land and fresh-water shells.
In the same books it is also stated that the best
mounting fluid is glycerine and water in the propor-
tions of one to one and one-half. But I find that the
fluid becomes coloured a deep yellowish brown soon
after the slug is put into it. — B. E. Smith.
Grey Lag. — In answer to "G. L. 's" inquiry con-
cerning " Grey Lag," as applied to the goose, I beg
to draw attention to the Cumbrian word laghter, brood
of chickens, setting of eggs, which is from the A. S.
I leegan to lay (eggs). The Grey Lag may therefore be
the Grey Egg- Amy-. — y. C. Clongh.
Green Hastings. — This cry undoubtedly is a
corruption of Green " Hasties," for Coghan, in "The
Hauen of Health," black letter edition of 1584, says,
" There be three sortes of Pease common among us
in Englande, — the first garden pease or hastie pease.
The seconde sorte is called graie pease. The thirde
greene pease, both growing in the fieldes." He then
gives the cooking of them at that time, and states
that " The two first sortes are used to bee eaten greene
before they be full ripe. First they are sodden, then
buttered, salted, and peppered. But if any student
list to eate greene Beanes or greene pease, let him
spare no pepper upon them, for this is a generall rule
in Galen for meates that be windie." Also it appears
at that day bread was made from peas, as further on
he says, "If pease be unwholesome, then the bread
which is made of them is unwholesome ; yet it is much
used in Lecestershire. But I leave it to Rustickes,

Strange Friends. — In my parish, Lordington
(Sussex), dwells a pretty little chestnut pony, of ad-
vanced years, who has been turned out to end his days
exempt from toil; and in the same park is a white
goose who has gone round the world with the British
fleet. Between these dissimilar animals a friendship
has sprung up. When any stranger approaches the
goose, it waddles off cackling towards the pony,
apparently for protection. The goose was, doubtless,
a great pet with the sailors. Has any one observed
a like anserine attachment ?- F. IV. Arnold.
Migrating Birds. — On dark nights from August
all through the autumn I often hear birds passing
over here. They make a constant whistling or piping
noise, and begin to come over as soon as it is dark.
They appear to fly in a westerly or south-westerly
direction. I have never seen any of them, because it
is only on dark nights that we hear these birds. Some-
times they seem quite close, just above the house-tops.
At the end of August in 1875, several letters appeared
in the Times about this migration. One correspondent
said, "Soon after eight o'clock on the evening of
Saturday, the 28th instant, my attention was drawn
to a strange noise over my house. It was raining in
torrents at the time, but I could distinctly hear, above
the .pelting of the storm, shrill cries, somewhat
resembling the note of the Sandpiper, and the flapping
of innumerable wings. This continued with scarcely
any intermission for hours, at any rate until after
twelve o'clock." This was eighteen or twenty miles
from Maidstone. Another correspondent said, "These
birds are frequently heard at Dover, and generally on
' dirty nights.'" I heard them here, for the first time
this year, on Friday, the 2nd of August, and again
on the following Sunday night, about ten o'clock.
Are they Curlews and Sandpipers, and how far does
their migration extend ? Perhaps some of your
readers could inform me. — Henry Lamb, Maidstone.
Colours of Dried Primroses. — A lady friend
has been very successful in preserving the colour of
the petals of Primula vulgaris by adopting the
following simple method. As soon as possible after
being gathered, the plant must be killed by washing
the roots for two or three minutes in boiling water,
then dried with a soft cloth, and immediately trans-
ferred to the drying papers, which should be well
warmed at the fire, and changed frequently, until
the plant is perfectly dry. The corollas of a number
of specimens she has treated in this way have preserved
all their original beauty of colour, and the leaves have
also retained their natural appearance. Some I my-
self dried, without first subjecting them to the hot
water treatment, lost their natural colour, and changed
to the bright green, which has annoyed so many
collectors. I have been very successful in drying
Orchids, by following the instructions given on page
88 of Science-Gossip for 1873, where it is recommen-
ded to clip the root and leaves in boiling water for a
few minutes previously to putting the specimens in the
press. — R. Standen, Goosnargh, Lancashire.
Geology of North Devon. — If " W. Downes "
would kindly give a few particulars as to his " finds "
in this district, and a few hints as to localities, he
would greatly oblige a native, who is now an occasional
visitor, and would be glad to make the most of his
time at his next visit. — IV. G.
Sea Anemones. — I should be obliged if "C. A.
Crimes" would kindly state in the next number of
Science-Gossip how he feeds the baby sea anemones,
as I find it an utter impossibility to make them take
the food. After their birth does he leave them where
they are or move them ? I should also like to know
whether he has any peculiar treatment for his B anodes
gemmacea, as I have been most unfortunate with mine.
Within a few days of placing them in the tank they
have a decomposed appearance, the colour fades, and
they are covered with a sort of slime. Sagartia venusta
I have succeeded very well with, and also Sagartia
bellis, but the " gem " invariably dies directly. We
once kept a Tealia crassicornis for three years, but
this also seems a very difficult one to manage.
— C. E. R.
Protection from Forest Flies. — Having
received personal benefit from the remarks in Science-
Gossip on the Harvest Bug, I send a perfectly trust-
worthy recipe for the protection of horses from the
Forest Fly. Smear the face and flanks well with
parafin oil. I have been here nearly three weeks with
my two young ponies ; they are not foresters, and one
cannot stand the fly at all without the oil. — Catherine
Middleton, Z yndh nrst.
Birds' Eggs in Wrong Nests. — The communi-
cations of Messrs. C. H. Sharp and A. F. Griffith on
the above subject brings to my recollection an incident
which happened in the north of Aberdeenshire, in
1865. When walking along the banks of a stream
which ran through a wood, my cousin disturbed a wild
cluck sitting on, and attempting to cover, eleven wild,
ducks and thirteen pheasant's eggs, which were all
crowded together in the same nest. — A. M., M'c A.,
Stoke-on-Trent.
Wild and Tame Ducks. — A pair of wild ducks
located themselves on a moat surrounding the house
of a friend of mine last October. During the severe
weather they came to the feeding-place of the domes-
tic ones, but otherwise kept themselves separate. In
the spring, a tame duck hatched a brood of young
ones near the haunt of the wild ducks, which now it
is supposed were destroyed by them. Soon after-
wards, the tame duck, whose brood was lost, was
caught in the act of drowning the progeny of the
wild duck, and succeeded in killing five of them before
being discovered. She was at once sent off to another
farm. In the same moat, several moor hens have
reared their young for years, taking their departure
regularly every winter. — J. Wiggin.
Barbots. — I enclose the following cutting from a
newspaper, and shall be glad if any of the readers of
Science-Gossip can tell me more of these insects (?).
The name is quite new to me. Are they only to be
found there ? Galignani states that a terrible accident
has just taken place at Biarritz. Miss Gordon, who
had passed the winter in Paris, was drowned while
out on an excursion. She attempted, without a guide,
to go along the cliffs far beyond the point marked by
the authorities as the limit for the public to go safely.
She reached a place known as the Falaise de la Mort,
and in stooping to pick a flower, her foot slipped,
and she was precipitated into a hole known as the
Barbots, a spot said to have this peculiarity, that at
the end of forty-eight hours nothing more than the
skeleton remains of any beings which fall into it. It
contains millions of small insects which devour the
body, and which are called by the inhabitants of the
district barbots, and are by them held in especial
horror. The Duke de Frias met his death under-
similar circumstances a few years ago.

Birds Singing at Midnight. — Extract from the
Standard, Feb. 22, 1878.— "W. F. E.," writing on
the above subject, mentions something much more
remarkable in the history of our singing-birds which
has occurred in the immediate neighbourhood of
Little Chart Rectory, Charing, Kent, within the last
few days. Between the hours of eleven and twelve
•o'clock on the night of Friday last, the 15th inst., on
Saturday night, and again on Sunday night, at the
same hour, the blackbirds and thrushes were singing,
whilst the smaller birds in the hedgerows were
chirruping and twittering just as you hear them in
the early morning in summer. He himself listened
to them with open door and window, and he has
been told by several who were out on those nights—
the neighbouring doctor amongst the number — that
they heard with wonder this, at such an hour, unusual
melody."
Birds Singing at Midnight. — The singing of
thrushes, robins, and other birds for several nights in
succession, during February last — although, doubtless,
accounted for by the singular beauty of the weather
about that time — is such an unusual occurrence, that
I should be very glad to hear of it prevailing generally
in the country. — X.
Brotherly Love in a Guinea-pig. — Some
years ago I possessed a guinea-pig which had never
shown any more wisdom than the rest of its species.
One day a friend gave me a young rabbit which he
had caught in a neighbouring warren, and I put it
into the guinea-pig's cage. I was somewhat aston-
ished to see the guinea-pig feed the rabbit "with
clover and other vegetables provided for its own
nourishment. It also gave up to it the snuggest part
of the cage. The guinea-pig continued these atten-
tions till the rabbit was sent back to its native warren,
when the unfortunate guinea-pig expressed its
anguish in most pitiful cries. — Anna Ward, Belfast.
Phosphorus in Salt Water. — I have observed
that when thunder is prevalent, the flashes of light

Ranunculus repens. — J have never heard the
name " Devil's-claw " applied to this plant. In this
part of Somerset it goes by the name of " Ram's-

to the rakers in the hay-field. — W. Herridge, Cack-
lington.

To -Correspondents and Exchangers. — As we now
publish Science-Gossip a week earlier than heretofore, we
cannot possibly insert in the following number any communi-
cations which reach us later than the 9th of the previous

E. H. (London). — No. 1. Everlasting Pea [Lathyrus sylves-
tris, L.) ; No. 2. Erigeron, sp. ; No. 3. It is difficult to name
a species from leaves only, but we believe your example to be
Oxalis acetosella, L.

Mountain Willow-herb {Epilobium montanum) ; No. 3.
Meadow Pea {Lathyrus pratensis, L.) ; No. 4. Common
Valerian {Valeriana officinalis); No. 5. Restharrow {Ononis
spinosa) ; No. 6. Bedstraw {Galium verutn) ; No. 7. Anagallis

No. 9. Red Dead Nettle [Lamium purpureum) ; No. 10. A
very curious and remarkable monstrosity of No. 5 ; we hope to
figure it in our columns shortly ; No. 11. Dead Nettle (Lamium
amplcxicaule) ; No. 12. Lesser Spearwort {Ranunculus Jtam-
muta).
Q. Q. (Elie Fife). — Unfortunately your example came to
hand in a poor state to determine ; it was partly decayed ; it
may prove to be Lycium barbarum ; have you another speci-
men ?
B. D. (Newport). — It is Cirsium oleraceuni. We cannot tell
why it is so named. Some of our thistles are edible.
E. W. (Bristol). — The Carex you send is Carex paludosa ; it
is nearly allied to C. riparia.
J. C. W. (Salterton, Devon). — No. 1 and No. 2 are both
Lotus tenuis, Kit. According to Hooker a sub-species of L. cor-
niculatus, L. ; but it is readily distinguished from that species
by its filiform and often shrubby stems.
G. W. Bell. — See article in Science-Gossip for July, 1877,
by Mr. J. Young, F.G.S., on " How to Clean Fossil Polyzoa."
A Subscriber. — The best book on British Butterflies and
Moths is unquestionably that of E. Newman. There you will
find illustrations of every species except the Micro-lepidoptera.
Morris's "British Moths" contains coloured plates, but they
are not so faithful as Newman's woodcuts.
W. G. Piper. — The lias, both at Lyme Regis and in the
neighbourhood of Whitby, is full of fossils. A capital hunting-
ground may be found at Aust Cliff, on the Severn, near New
Passage, where there is an abundance of Rhoetic fossils. The
carboniferous limestone at Castleton, Derbyshire, is a splendid
fossil locality. The tertiary beds in the Isle of Wight are also
exceedingly fossiliferous.
C. E. R. — You can purchase Sea-Anemones of Mr. King,
Seahorse House, Portland-road, London.
F. W. E. S. — Your article will appear shortly in our pages.
J. W. S. (Sheffield). — Your exchange exceeds the three lines
allowed gratis, and would have to be charged as an advertise-
ment.
Essex. — The insect you trod upon which gave forth a phos-
phorescent light was most probably Geophilus ellctricus, one of
the Millipedes.
J. R. Murdoch. — Your Mosses are : — No. 1. Hypnum
Sendtueri ; 2, Hypnum purum ; 3. Hypnum tamariscinum ;
4. Hypnum loreum ; 5. Hypnum piliferum ; 6. Hypnum

7111m myosuroides ; 13. Bartramia fontana ; 14, Homalia tri-
chomanoides. Hepaticae : 9. Madotheca platyphylla ; i$.PZa-
giochila asplenioides ; 16. Scapauia nemorosa.
A. Cole. — Your Mosses are : — No. 1. Sphagnum Jimbria-
tum ; 2. Sphagnum acutifolium : 3. Sphagnum subsecundum
(var. contortum) ; 4. Sphagnum cymblfolium (var. squarrosu-
lum) ; 11. Sphagnum cuspidatum ; 5. Hypnum Jlagellare ; 6.
Dicranum scoparium (young); 7. Hypnum rivulare ; 8. Ce-
ratodon purpureas ; 9. B>yum caspiticium ; 10. Hypnum ser-
pens ; 12. Hypnum sericeum.
A Beginner. — The insect you describe was most probably
one of the Hornet Clear-wings, a moth which simulates the
appearance of the true Hornet in a remarkable degree. See
Newman's " British Moths."
A. W. A. — 1 here is a capital old-established Naturalists' Field
Club in Liverpool, whose subscription is low, that would suit you
and such as you, and we feel certain it would welcome artisan-
naturalists. The president is the Rev. H. H. Higgins.
C. H. G. — The caterpillar of your moth had been attacked
during life by an ichneumon (a not uncommon thing), and the
ichneumon had deposited its eggs in the tissues of the caterpillar.
These subsequently hatched into the condition you found them
in, at the expense of their host.
X.— Your packet contained some of the purifying lime used
in gas-works.
J. Kirkham. — The six ivory slides are very heterogeneous
as to objects, and old-fashioned. No. 1 contains a piece of Red
Seaweed {Plocamium) and of a Sea-fir {Sertularia argentea) ;
No. 2 shows wings, legs, &c. of some orthopterous insects ; No.
3, Fish-skin. Feather-barbule, &c. ; No. 4, pieces of Snake-
skin and part of a Beetle ; No. 5, Coral-sand, portion of
Diamond Beetle, of Sea-mat (Flustra), &c. ; No. 6, piece of
Cora Una officinalis (a Sea-weed), of Flustra, and a group of
Foraminifera (Gtobigerina). Please send us your address, as
we have mislaid it.

limestone. On mentioning this to Mr. Lonsdale, he
at once adopted the suggestion, and named a species
of the Silurian strata Fenestella Milleri (Lonsd.).* In
1 841 Phillips himself adopted this term.
This more expressive generic term has since been
adopted by nearly all writers on Palceozoic Polyzoa ;
and Lonsdale gave as a description of the genus,
characters altogether different from Retepora, and
more in accordance with known facts. It is impos-
sible for me to give the exact description as given by
* Phillips's " Palaeozoic Fossils of Cornwall, &C." Through
the kindness of Mr. Plant, curator and librarian of the Peel
Park Museum, Manchester, I have been allowed to extract
whatever I required, and trace the original figures of specimens
from this rare volume.

Lonsdale — not having his works at hand to refer to —
but the following is taken from M 'Coy's " Palaeozoic
Fossils " : — " Polypidom calcareous, cellular, forming
a conical or fan-shape expansion of radiating branches,
interstices connected by transverse dissepiments ;
exterior surface of branches rounded, covered by
tlense minutely porous layers ; inner surface with a
keel along the middle, separating two rows of mouths
of short tubular cells, which extend a variable length
obliquely downwards and inwards into the interior of
the branch : dissepiments usually without cells,
occasionally a row of small cells on the mesial keel.
Non-celluliferous side formed internally of a layer of
vertical capillary tubes." This genus was placed by
M'Coy among his Family, Group Myriaporid.'E, a

group which embraced the genus Retcpora of
Lamarck ; the Elasmopora of King ; the Glanconome
of Goldfuss restricted by Lonsdale ; the Penniretopora
of Prodomas ; the Acanthocladia of King ; together
with the sub-genera Fcncstdlina and Reteporifia of
D'Orbigny.
The first recorded appearance of this genus is in
the Bala beds of the Lower Silurian series. In Morris's
Catalogue, and also in Jukes's " Student's Manual,"
1857, it is recorded as appearing in the Upper
Silurian, in company with many other forms of
Polyzoa. In the later edition of the Manual this
may have been corrected, but I have not seen it.
But in Morris's earlier Catalogue, which he began in
the 1st volume of the Geologist, Fencstella snbantiqna,
D'Orb., and F. Milleri, Lonsdale, are given with the
Lingula, Llandello, and Caradoc or Bala Bed fossils.
From either the figures or even the specimens, it is
very difficult to make out the true character of
F. Milleri. The habit of the species as impressed
upon the Bala shale is peculiar and characteristic.
It is partially flabelliform, but not universally so, as
some of the branches cross and recross the under ones ;
thus obliterating the true character. The interstices
are thin, and according to the description, the dissepi-
ments are narrow and slender, and two lines apart.
The fenestrules are five or six times longer than wide,
with about twelve pores to the fenestrules.
If this be a true description of the species,
F. Milleri is a marvellous specimen of the
earlier Fenestella group. Fenestella Lons-
dalei, D'Orb., is figured in Sihtria, and is
given by Morris in the earliest, as in the
latter catalogue. It is found in the Dudley
limestone as well as in the lower beds,
and if the synonyms be true, the species
had a very wide range, as it is figured as
an American species as F. prisca, and
Morris, in his catalogue, gives F. prisca
as a synonym of the species. The figure
before me is cup-shape, attached by a
broad base to some foreign object. The
outline of the margin of the cup-like form
is entire, and the poriferous face will be
on the inside, like modern species of
Retepora and Hornera. It seems to be a
good species, and habit alone would be a
sufficient character. F.snb-antiqna, D'Orb.,
is another Silurian Fenestella ; but among
synonyms of this are given F. antiqna,
Lonsdale, Retepora antiqna, Goldfuss, and
R. membranacca, Phillips : it may be a frag-
ment of some larger specimen of F. prisca.
D'Orbigny's species, as recorded and de-
scribed in his Palaeozoic Fossils, has a
corallum very slender, with straight inter-
stices, seven or eight of these measuring
only two lines ; the dissepiments are thick,
and the fenestrules are rectangular or
oblong, about three lines longer than wide. The
pores are small, thick, with prominent edges, their
own diameter apart, and six or seven to the length of
the fenestrules. F. reticulata, Lonsdale, is a species
that has been often confounded with Hisinger's
Retepora, so much so, that M'Coy draws attention to
the fact, acknowledging that it is scarcely possible to
determine the specific character, as no information is
given relative to the pores. Yet, as his species of
Retepora Ilisingeri ? agrees in some particulars with
the original, he would even add confusion to the con-
fusion, and name it R. retifonnis, even though Mr.
250
HARD WICKE'S SCIENCE- G OSSIP.
Lonsdale had applied the term to "a very similar
corallum, which he, however, places with the genus
Fenestella, and figures with only the two rows of
pores usual in that genus."
F. pat ida, M'Coy, and F. rigidula, M'Coy, are
good forms and very well described. The corallum
of F. patula is small and semicircular, about half an
inch in diameter. The interstices are broad, strongly
carinate, slightly flexuous ; the dissepiments are
strong, and the fenestrules are a little wider than the
interstices ; the pores are large and prominent, about
3 or 4 to length of fenestrule. Its general features
and character are very much like some of the smaller
species of the Carboniferous limestone. The figure
of F. rigidula is peculiar and striking, and it much
resembles some of the Devonian species of Nicholson.
The following, however, is M 'Coy's note on the
synonyms of the several species :—
"Fenestella antiqua, Lonsdale = F. subantiqua,
D'Orb.
F. antiqua, Goldfuss, is a distinct Devonian form.
F.prisca, Goldfuss, Silurian = F. rigidula, M'Coy.
F. elegans, Hall, Silurian = F. rigidula, M'Coy.
F. assimilis, Lonsdale, Silurian."
My list contains the names of three other forms.
Dawson describes one by the name F. Lyelli, and
Hall figures and describes two other species from the
Clinton series of America,—^, aibosa and F. tenui-
ceps. There are figures of these species, I believe, in
Dana's Manual.
I could not pretend to give anything'like exactness
to my review of the Silurian species of Fenestella.
To say that the whole of the descriptions are very
foggy, would be perhaps vulgar denunciation, but it
would be nevertheless a fact. And before altering
my formerly written paragraph, which was less
sweeping than this, I have gone over again the whole
of M 'Coy's figures and descriptions. These are
good so far as they go, but they do not come up to a
proper analysis of the specific characters of the genus
which modern biological, or even palreontological
studies demand. Too much dependence has been
placed upon the isolated fragments, which give only
a partial view of the true ideal of specific type. In
reviewing the Carboniferous Fenestella I shall be able
to make this more clear.

HOLIDAY RAMBLES IN ST. OUEN'S BAY'
" Q HALL it be Scotland or Jersey? " was the ques-
O tion put when arranging for a botanical tour;
and though the flora of Clova, Glen Isla, Braemar,
and the Grampians is sufficient in itself to make a
holiday enjoyable, but when the additional advantages
of lovely scenery and health-giving mountain breezes
are added, it must indeed be a rich and peculiar flora
to outweigh them ; but possibly it was the long
monotonous spring, with its absence of sun, that
caused the Channel Islands to exert a spell so mag-
netic that not even the presence of the "silvery
streak " was sufficient to break or neutralize its in-
fluence. So, having prepared for work by spending
a day among the oaks of Whittlebury Forest, whose
natural history has yet to be written, and glorying in
another at Kew, we proceeded with considerable
misgivings to cross from Southampton by a passage
whose horrors had been sufficiently dwelt upon by
candid friends ; but, thanks to the soporific effect of
the daily literature we had assimilated, we slept a
dreamless sleep as we passed through the Solent and
the chops of the Channel. Arriving at St. Helier's,
in Jersey, we noticed the slopes of Fort Regent were
brilliant with Medicago maculata, Silene Angli:a,
Linum angustifolium, Tragopogon porrifolius, Sedum
Anglicum, and two or three specimens of Gladiolus,
which had established themselves there. But it would
be wearisome to give in detail the various plants seen
on the different days spent in Jersey ; sufficient to
say, that, having beautiful weather we visited the
rocky Corbieres, home of the seabirds, enjoyed the
delightful breezes on the samphire-covered cliffs of
Pleinmont, the only Jersey locality for A. ca pill us
veneris, admired the ivy-covered castle of Mont
Orgueil, the shady lanes of St. Saviour's, home of
Arum Italicum and Sibthorpia, and had taken the
rather noisy coach-rides by Beauly Bay, with its view
of sunny France, and the romantic gardens of Rozel,
not to speak of the sea-bathing, which the firm sands
and clear water render so pleasant, and the entomolo-
gical hunts after Thecla rubi, Cinxia, Edusa, Cardui,
and Daplidice, on the hot slopes of Noirmont Point
and Greve de Lecq ; while the enormous cow-cab-
bages, the fig-trees, and extensive vineries had been
properly inspected. So, in order to give some idea
of the peculiarly rich and extensive flora of Jersey,
one day shall be used as a sample, comprising, as it
did, some of the best and most typical plants. Its
route may be shortly given as follows : from St. He-
lier's to Beaumont, thence to St. Ouen's on to L'Etac,
returning by St. Ouen's Bay to La Moye and St. Bre-
lade's. The distance walked would be from 24 to 26
miles. The success of the day was owing to the
company of Mr. Piquet, who is compiling a new flora
of Jersey, and the previous reading up of Babington's
"Flora Samicrc." Shortly after leaving the nau-
tical-looking station of St. Helier's, the rail, which
HARD WICKE'S SCIENCE- G OSS IP.
251
runs round St. Aubyn's Bay, was bordered with
Borago and Anchusa sempervirens, common viatical
plants in Jersey, followed by great quantities of
CEnotJiera odorata. Dismounting at Beaumont, and
walking to Bel Royal we found Alyssum maritimum,
and then visited St. Peter's Marsh, where Ranunculus
cphioglossifolius, Cyperus fuscus, and Isnardia palus-
tris, formerly grew, but with the drainage of the
marsh and its subsequent cultivation these rarities
have disappeared. Mr. Piquet, however, pointed
out the exact spot where he had last gathered the
Ranunculus. At Bel Royal, in Professor Babington's
locality, we gathered Hemiaria snbciliata, growing
in straggling dark green patches, not unlike Thymus
Serpyllum. Near it we also found Allium sphero-
cephalum and vineale, Silene conica, whose prettiness
is lost by drying, and CEnolhera in great plenty.
Passing through one of the shady lanes we gathered
Scrophitlaria Scarodonia, which takes the place of our
nodosa and aquatica, the two latter being rare in
Jersey. On emerging into the bright sunlight we
noticed the pretty Lotus hispidus and Sednm An-
glicum, while the gardens of the nice little villas
were blazing with Jlfesembryanthemum and Gazonia.
Nearing St. Peter's, on a shady wall we came upon
the Jersey Fern, Gymnogramma lentophylla, in abun-
dant fruit, but losing its colour, May being the month
for it in perfection. On the way to St. Ouen's Manor,
about Vinchelez, where we had previously caught a
fine specimen of the Jersey Lizard, Lacerta viridis,
before it threw off its tail, as did another we caught
near St. Brelade's. In these oak-shaded lanes ento-
mologists possibly would have been pleased by the
strong odour emitted from hundreds of the goat
caterpillars which infect and destroy many of the
trees about here ; but to us the smell of Allium trique-
trum that haunted our vasculi was deemed preferable.
Gratefully accepting the invitation to visit the Manor
H ouse, we went over one of the ancient homes of
Jersey, — the ancestral seat of the Carterets ; and had
we been archaeologists, we might have reported upon
the quaint oak carvings and mullioned gables ; but
being only botanists, we most enjoyed the view over
the island, down the well-wooded valley to the coast
of St. Ouen's wide-stretching bay, and the pond,
dear to botanists, the ultima Thule of our journey :
while, above us, the grand old chimneys, covered with
white and pink snapdragons, and the thatch-roofed
outhouses, covered with such profusion of Cotyledon,
surpassing any previously noticed, — not excepting
Pandy Mill, delight of artists, the rocky lanes of Car-
marthen, or the peat-topped walls of county Mayo.
Leaving St. Ouen's we came upon a marshy piece of
ground, where Lythrum hyssopifolium was plentifully
growing, though, of course, not in flower. Ranun-
culus hirsutus, Orchis latifolia, Bartsia viscosa, and
Hypericum elodes, also occurred. Nearing L'Etac,
the roadsides were bordered with Siuapis incana, and
a. wet meadow was adorned with the rich purple
Orchis laxifiora. Chenopodium muralc occurred in
the village, Atriplex Halitnus being used as a
hedge-plant.
St. Ouen's Bay is about six miles long, and is bor-
dered with sandy tracts cultivated wherever possible,
in some cases potatoes being planted in the actual
sand, where Carex arenaria and Festuca rubra are
agrarian weeds ; but the uncultivated portions shone
as a field of gold with Raphanus, Brassica, Cheiran-
thus, Sinapis incana, and other Crucifene. The road-
sides yielded Lotus diffusus, Allium vineale, Silene
conica anglica, Trifolium striatum and subterraneum,
with stems iS in. high ; while, growing among the
silvery abundance of the long-awned Bromus maximus
and Festuca unigiumis, appeared Medicago minima
and Armeria plautaginea, with other sand-loving
plants.
On the hot toilsome walk across fields of small
dimensions enclosed by stone walls of rickety struc-
ture, specimens of Orchis laxifiora, Bartsia viscosa,
Cyperus longus, and CEnanthe crocata were noticed.
An exploration [of the shingle was next attempted,
when a solitary specimen of Crambe, a very rare
Sarnian plant, was seen. Euphorbia Paralias was
frequent, and is occasionally frequented by the larvae
of Sphinx Eicphorbii. Diotis maritima was not
plentiful, but Atriplex arenaria, Salsola kali, and
cakile were very common. Standing by the shingle,
and looking over to the sand dunes, a beautiful sight
was presented by the great quantities of Matthiola
sinuata in magnificent bloom, growing with the
glaucous Eryngium and glaring golden Brassica.
By the second Martello tower a nice patch of Lagurus
cvalus occurred, and plenty of Orobanche amelhystea,
while here and there might be seen bleached skeletons
of Mibora minima. Between the sea and the hills
appeared great patches of Ceutaurea aspera, the lower
flowers of which were only in bloom. On i-eaching
the hill slopes, a complete mass of beauties presented
themselves, so that the exclamations of admiration,
which had been popping off at no distant intervals
all day, now came by volleys ; and down we lay
among thousands of Dianthus prolifer, Linum angus-
tifolium, Orobanche ccerulea, Centaurea aspera, Cen-
taurea paniculata, and Scabiosa maritima. Next came
a descent to St. Ouen's Pond, where, having seen
Cladium Mariscus, we came upon Scirpus Tabernce-
montana, followed by its rarer relative pungens, and
eventually maritimus and pa uciflorus ; then came the
prettily-veined leaves of Potamogeton plantaginens
and the fugacious flowered Alisma ranunculoides ;
after which a long search was made for the leaves, —
it was too early for the flowers, — of Spiranthes a>sti-
valis and Epipactis palustris. On the road to the
Corbieres, Kaleria cristata, near albescens, Coryne-
phonts canescens, Radiola milligrana, Trifolium
arvense, Lepturus filiforme, Convolvulus Soldanella,
Bromus Lloydianus, and Schlerochloa loliacea were
found, but Solatium mittialum searched for without

success. On the hill-slope below La Moye came a
tract of ground covered with Sarothamnus prostratus,
on which grew some fine Orobanchc major. About
here Mr. Piquet had a week previously found Linaria
Pdisseriana in plenty, but as we had searched with-
out success a few days after, were not very sanguine
about adding it to our store ; but, however, we care-
fully searched among the Cusitela-covered Ulex and
prickly Ritscus, and then, as these became less fre-
quent where the hill-side was purple with Echium
violaceum, and then higher still among myriads of
Sedum Anglicum, yuncus capitatus, Trichonema
columnce in fruit, Radiola milligrana, Helian-
t/iemum guttatum surrounded with its quickly-
falling petals, Sikne conica, Lotus angustissimus,
Aira pnvcox, and Euphorbia Portlandica, but no
Linaria. Some Jersey cows were browsing
eagerly about the gorse clumps ; and as Mr.
Piquet said they are very fond of the Linaria, its
disappearance was at once laid to their charge.
As no ready means of revenge presented itself,
another search was made, this time rewarded with
Asparagus prostratus and Aspknium lanceolatum,
and at last, with the real Simon pure in fruit.
Having mercy upon it, we selected only a scrap
or two, and, elated, set off at a fast rate for St.
Brelade's, where suddenly we had to halt to avoid
the desecration of trampling upon a few hundreds
of Trifolium strictum growing some 10 in. high. De-
scending to St. Brelade's, Silene nutans, Silene quinque-
vulnera, Scdum dasyphyllum, and Delphinium Ajacis
were picked. The road to St. Aubyn's was bordered
with Silene nutans and Scrophularia Scarodonia ;
while, with vasculi, hats, books, and hands full of
specimens, we trudged along up the sandy road,
scarcely deigning to notice Polycarpon tetraphyllum,
Oxalis stricta, Epilobium lanceolatum, and Hie-
racim pilosis si mum, reaching St. Aubyn's in time for
the train to bear us round the beautiful bay to St.
Helier's, where something more solidly sustaining
than cocoa had to be discussed previously to putting
in press our numerous and rich collection.

AN AUTUMN RAMBLE IN
EPPING FOREST.
Part I.
By Dr. De Cresitgny.
TO procure specimens of a late-flowering and
uncommon Chenopod (C. nrbicum) from a
locality on the borders of Epping Forest, we had
lately occasion to make an excursion in that direction,
when the opportunity was taken advantage of for a
ramble through the shaded dells and broken uplands
of the forest in search of fungi, which are always to
be found there on the setting in of the autumnal
rains, in great variety and abundance. Many clearances
have been made of late years in the neighbourhood
of Walthamstow and Wanstead ; consequently,
although there are still many unenclosed patches of
woodland thereabouts, of which the most consider-
able extends southwards of Wanstead, we can hardly
consider ourselves fairly within the precincts of the
forest proper until we have left Woodford behind us.
Traversing, then, one of these detached woods — that
which lies between this place and Walthamstow, — we

turndown the Chingford road into the hollow below,
where a lane, right, leads into a copse bordered by
a rill and a narrow strip of pasturage ; beyond, left,
is the warren and farmhouse, well known to ex-
cursionists as Queen Elizabeth's Lodge ; onwards, a
footpath to High Beech Hill. Forcing our way in
this direction, at one time with difficulty through

pollard oak and hornbeam, where bramble and
blackthorn scrub gave place to an undergrowth of
bracken, and where progress was easier and less
irksome, we gathered as we went anything and every-
thing in the shape of fungus we could see, retaining,
however, only two or three specimens of each kind.
From the "King's Oak," near High Beech, the high
road to Epping traverses the very heart of the forest :
hence it is not far from an ancient intrenchment,
called " Amesbury Banks," and whence we retraced
our steps through dense thickets and interminable
groves of lopped beech and other trees, until we
reached the picturesque slope which rises behind
Loughton.
As anticipated, the heavy rains of August had
i produced a more than usual abundant crop of fungi ;

and on sitting down next day to examine and sort
the contents of our pockets, hat, and vasculum, we
felt fairly bewildered at the sight of the spoils, and
hurried multitudinous entries in our note-book.
To take them scientifically, and in proper order of
sequence, let us commence with the Agaricini ;
those with a gilled or plated hymenium : these, of
course, were the most numerous, and were easy to
separate from the rest. Referring to " Berkeley's
British Fungology," we find that they are all included
in fifteen genera, of which some three or four are
rare, or have but few representatives in England ; on
the other hand, the Agarics proper are so numerous
as to comprise twenty-seven sub-genera, arranged in
five sections, according as the colour of the spores
is white, salmon-coloured, tawny or ferruginous,
purplish or brown, and black. The characteristics
254
HARD WICKE >S S CIE NCE - G O SSIE.
of the genus are persistent membranous gills and a
filamentous trama continuous with the pileus ; but
those of the sub-genera are very miscellaneous and
confused : differences in the character of the velum
or veil, whether present or present only in the form of
an annulus, or wanting entirely in any shape ; con-
fluence or otherwise of the hymenophorum with the
stem ; decurrence or other peculiarity of the lamella; ;
peculiarities of the stem, of the pileus, of its margin ;
presence of a volva or absence thereof. In one sub-
genus there is no stem — Pleitrotus. Of this we gathered
a specimen from the dead trunk of a tree : the gills
•are narrow, and margin of the pileus remarkably in-
curved. Illustrative of the scaly-cuticled sub-genus
Lepiota we found a few specimens of L. rachoides
growing singly in a hedge ; besides this peculiarity, it
has a stem furnished with an annulus, and is alto-
gether a pretty little plant. Not unfrequently A.
{Amanita) riibescens was met with, rather a hand-
some fungus with a brownish warty cuticle and white
gills, bulbous and ringed stem : the rubescent cha-
racter is not very decided, sufficiently so, perhaps, to
warrant the use of the term ; the bulb and stem when
broken exhibited this characteristic more clearly than
the pileus : edible.
Less frequent was another, — not edible as this, but
very poisonous species, A. {Amanita) plialloides, with
stem strongly ringed, and a bulb furnished with a
volva free above ; white, except the upper part of the
pileus, which has a yellowish tinge. A ringless but
bulbous fistulose-stemmed Amanita we found in A.
Cecilia, also furnished with a volva, and with a pileus
more persistently waited than that of A. rubescens.
It is a much smaller species, and the brownish colour
of the pileus is of a colder shade, greyish or mouse-
coloured. A. {Tricholoma) nudus we observed only
in one place, a handsome, but probably very dan-
gerous mushroom : there was one small patch of it,
three or four growing closely together (fig. 206).
Pileus obtuse, moist, pale violet shaded with brown ;
gills and short, thick bulbous stem of a beautiful
violet throughout. The warted scarlet pileus oi A.
muscarius we looked for in vain, — one of the hand-
somest, at the same time one of the most poisonous of
its tribe. ( Tricholoma) A. ptrsonatus is more frequent,
but grows singly, here and there, in open grassy
places : the pileus is convex, obtuse even, moist and
of a pale ochre-colour; gills dirty white, stem ring-
less, firm, and covered with a stain of pale violet.
On the stumps of decayed or felled trees was the
well-known A. (ITyplioloma) fascicularis, with its
dull rufous-coloured pileus, passing into yellow at the
borders, yellow fistulous stems, and greenish-grey
gills : and in many parts of the forest growing in
patches, often of a circular- form, H. sublaterilius,
much like the preceding species.
Examples of a section of Agarics (among our
specimens), characterized as having pilei clothed with
fibrillose scales, usually umbonate (a), or sub-
umbonate [b), and fibrillose stems, we have in two
kinds of Hebeloma ; the colour of the cuticle in a is
golden brown : and in A. (Clitocybe) laccatus we have
a pileus the very reverse of umbonate, viz., the umbi-
licate form : it grows on dead leaves abundantly in
the forest ; colour variable, from flesh-coloured to
cinereous grey and pale cobalt. Clitocybe candicans
is also plentiful. On the margin of a pond, not far
from the "Wake Arms," we obtained several fine
specimens of A. (Pholiota) aitreus, a mushroom re-
markable for its pileus brilliantly coloured of a golden
tawny hue, and, examined with a lens, sprinkled with
closely adpressed or innate hairy scales of an orange
colour, which impart no doubt a brilliancy to the
plant in its living state, but which fades away when
no longer fresh.
Last, and not by any means least of the Agarics,
is a tall species of Collybia (C. radicatus), plentiful in
the wood behind Loughton. It is furnished with a
long tap-root, the stems at least six inches long,
slender, and tapering upwards ; pileus of a greyish
brown, smooth, moist, plane, and umbonate.
(To be continued.)
A GOSSIP ABOUT NEW BOOKS.
ON nothing does a "war fever" leave its mark
more impressively than scientific literature.
The tide of true progress is then stemmed, if not
rolled back. The literary history of the last two
years proves how few important works of science
have issued from the press. And yet that period has
been marked by scientific discoveries of the most
important and even sensational character. It is the
epoch of the Telephone, the Microphone, and Phono-
graph ; of the Radiometer, Otheoscope, and other
instruments, which revealed to us the molecular mys-
teries of matter.
It is with much pleasure that we turn to a short
notice of a few books which have for the last month
or two been accumulating on our library table. The
short space at our disposal does not enable us to do
that justice to some of them which they require.
"Tropical Nature," by Alfred R. Wallace (London :
McMillan & Co.), deserves a leading place in any
notice of new books. The volume consists of a series
of essays, chiefly relating to animal and plant life in
equatorial regions, speculations as to the colours of
birds and animals, flowers and fruits, and how they
have arisen through the process of natural selection.
All are written in that delightsome manner which
characterizes Mr. Wallace's other books. The chapter
on humming-birds is one of the most charming ever
penned by its original writer. That on the distribution
of animals as indicating geographical changes is a re-
markably clear piece of philosophical generalization.
By this time most readers of natural history will have
read " Tropical Nature," and our advice to those who
have not yet had the opportunity is that they should

read it as soon as possible. " West Yorkshire ; an
Account of its Geology, Physical Geography, Clima-
tology, and Botany," by Messrs. James W. Davies
and F. Arnold Lees (London : L. Reeve & Co. ). This
book contains much valuable work. Few counties
are more interesting geologically than Yorkshire, and
many books and papers have been written upon it.
All of these have here been duly arranged chrono-
logically, and the authors always refer to such of their
literary predecessors as have furnished them with
material. The geological portion is written by Mr.
James W. Davies, the hon. sec. of, the Yorkshire
Geological Society, and all geologists will acknow-
ledge that he has done his work conscientiously and
well. The second part, devoted to physical geo-
graphy and botanical topography, is the joint work
of Messrs. Davies and Lees. The arrangement of
the material is most excellent, and so clear and sug-
gestive that the reader is enlightened instead of being
perplexed by its abundance. Numerous maps and
engraved sections assist the text, and these are of
excellent execution. The geological structure of York-
shire is treated of in detail, from the Lower Silurian
beds to the Glacial series. The physical geography
and topographical botany then follow in order, and
one sees almost at a glance the relation between plant
distribution and the physical geography of the valleys
in which they occur, or the geological structure of the
underlying rocks. A handsomely got-up volume of
upwards of 400 pages thus represents a most creditable
scientific industry on the part of the authors.
The new term of Physiography (as Physical Geo-
graphy is now called) has called forth a series of
"manuals" devoted to its exposition. How import-
ant is even an outline knowledge of nature has been
shown by the success of Huxley's little book on this
subject. There is always the danger of causing
shallow-minded students to imagine they have nothing
more to learn when they have acquired a well-defined
idea of natural phenomena as a whole ; and on that
account we object to ' ' physiography." But if books
have to be written on this subject, they may as well
be in good hands ; and we are therefore pleased to
notice " The Physical System of the Universe," by
S.J. Skertchley, F.G.S. (London: Daldy, Isbister,
& Co.), which is intended as a manual of physio-
graphy. It is a book, however, which will delight
those who do not intend "going in for examination"
more than those who do, for it is a well-written and
very clear outline of the universe as a whole, and of
the unity of natural forces. We know of few recent
books which comprehend so much in so limited a
space. All the recent discoveries in physical, natural,
and geological science are included in Mr. Skertchley's
book. It is a work which we hope will be read with the
same pleasure that we have ourselves derived from it.
"A Science Primer," by the Rev. Dr. Macvicar
(London : W. Blackwood & Sons), although a
small book in comparison with those above men-
tioned, is a remarkable one in many respects. It
professes to deal with "the nature of things." Its
author is a man possessed of great ability, extensive
reading, and a brilliant power of speculating. There
are many subjects briefly discussed, especially those
relating to molecular physics, which strongly impress
us by the undoubted ability and originality of view
with which they have been treated. Our readers will
not always agree with the author, but few will come
away from this suggestive little book unimpressed
with new ideas.
" The History of Glanville's Wootton," by C. W.
Dale (London : Hatchard, Piccadilly), is a detailed
account of the archaeology, zoology, and botany
of a district in Dorset, after the manner of White's
" Selborne," only arranged in chapters, instead of
being given to the world in the form of letters. The
book is very well got up, with capital paper and in
clear type, and the few photographs which illustrate
it are excellent. As for the rest, the work consists of
lists of animals, vertebrate and invertebrate, and of
plants, phanerogamous and cryptogamous, which have
been found in the district of Glanville's Wootton.
Mr. Dale has devoted much time and careful labour
to his task, and as a consequence has given a very
valuable little monograph to the world.
" A Handbook for England and Wales " (London :
John Murray), which should give, alphabetically ar-
ranged, a short and trustworthy account of every town,
village, and place of importance, with all relating
to them of archaeological, geological, botanical, or
geographical interest, was a happy idea. A handier
book of reference could hardly have been prepared
than has been now compiled. All depended, how-
ever, upon the author and his ability to select just
such material as would be valuable to the traveller,
tourist, or student. We are happy to say that this
has been done in the present work, and that, having
tested, from personal knowledge of numerous places
referred to, the pains taken by the author to insure
accuracy, we believe it to be one of the best books of
its kind which the well-known publishers have issued.
"Holmes's Botanical Note Book," by E. M.
Holmes, F.L.S. (London : Christy & Co.), may be
utilized by the student as a means of acquiring a
practical knowledge of botany. It contains diagrams
showing the parts of flowering plants, directions for
examining plants, the microscopical examination of
plants, directions for describing plants in schedules,
and a glossary. The schedules, however, form the
principal part of the work, and these may be obtained
separately of the publishers. The printed head-lines
oblige the student to note down every feature of a
plant, and in this way he will soon learn to look out
for particulars which are too frequently shunned,
because deemed troublesome to detail. We are
much pleased with Mr. Holmes's note-book, and
heartily recommend it to students.
"A First Catechism of Botany," by John Gibbs
256
HARD WICKE'S SCIENCE- G OSSIP.
(London: Simpkin, Marshall, & Co.). This is
a new and enlarged edition of a very noteworthy
little book, written by a botanist who is a fre-
quent contributor to our pages. We have before
expressed our liking for the book, and are glad to
see it revised and enlarged. All young botanists
would do well to get it. " The Creation of Moses
and Science in Harmony," by Dr. Alex. Stewart
(London : Elliot Stock), is another of those laboured
productions in which so much intellectual force is
thrown away in attempting to harmonize what have
never been disturbed, except by men themselves.
They frequently consist of bad geology and weakened
theology, and are usually unsatisfactory. Correct
science needs no harmonizing : incorrect science soon
gets corrected. Meantime the great truths which
theology has in its keeping have a sphere entirely
apart from scientific investigation. As might be
expected, the greater part of the book under notice
is devoted to demolishing the theory of evolution.
Would that such writers were wise in time ! No
" reconciliations " would then be needed.
To turn from these unsatisfactory subjects to note
the appearance of the ninth edition of Proctor's
"Half-Hours with the Stars " (London : Hardwicke
& Bogue), is a pleasant change. The twelve plates
of the maps are new, and in bolder execution, so
that the astronomical student is considerably aided
thereby. It augurs well for the spread of astro-
nomical science when books of this class are so well
received and largely circulated.
A capital little book on human physiology, simply
but attractively written, is Mrs. F. Fenwick Miller's
"House of Life" (London: Chatto & Windus).
It is a work which should be in every family library,
not to lie idly on the shelves but to be read by every
member. "The Sight, and how to Preserve it," by
Dr. H. C. Angell (London : Hardwicke ik Bogue),
is another work of a similar kind, bringing within
intelligent knowledge those parts of our own frames
about which we have hitherto been in such culpable
ignorance. Perhaps no sense is so much valued by
us as that of sight, and there is scarcely any other so
abused. Take one hundred people whom nobody
would call other than educated, and let them answer a
few questions as to the structure of the eye and the
nature of vision, and perhaps not five would pass the
examination entitled to an elementary certificate !
This ought not to be ; and it is pleasant to see the
leading medical specialists devoting what little spare
time they have to popularly instructing the masses in
the subjects to which the former have devoted long and
useful lives. Nothing could be more understandable,
more practical, or more useful, than Dr. Angell's re-
marks on " The Sight and how to Preserve it," and
everybody with eyes ought to read them.
"Nutrition in Health and Disease," by J. H.
Bennet, M.D. (London, J. & A. Churchill).
This is the third edition of a valuable work,
chiefly written for public rather than special
readers, but which the latter cannot fail to estimate
very highly. The title is a very happy one, and
rightly expresses the character of the work. Its
aim is the same as that of the two little works just
mentioned, — the endeavour to make people acquainted
with their own bodies, and what is taking place in
them every hour of the day under the name of
"nutrition." " Phosphates in Nutrition." by M.
F. Anderson (London : Bailliere, Tindall, & Cox), is a
work of a similar important nature. Its endeavour is
to show the importance of certain inorganic materials
in the food, and their functions in the tissues. In
this way the author's views lead him to some novel
explanations of the causes of certain diseases hitherto
but little understood. The chapter on the "Mineral
Theory of Wasting Diseases " is especially noteworthy.
"English Folk-Lore," by the Rev. T. T. Dyer,
M. A. (London: Hardwicke & Bogue), cannot
fail to be a popular and widely-read book. " Folk-
Lore," or the wisdom of the common people, as
expressed in their proverbial and other sayings, has
of late years been a fruitful study. All of us are
acquainted with some of these sayings, and their
quaint utterance frequently carries us back to the days
of our childhood. There are scarcely any natural
phenomena which have not been thus noticed ; whilst
the pages of our best poets frequently sparkle with the
richest and quaintest of these gems of folk-lore.
Mr. Dyer's book is a very attractive-looking volume,
both outside and inside, for it has been given to the
world in a handsome cover and good paper and
print,— the very auxiliaries to make such a work
successful. The author is very happy in his style,
for it is light and airy without being flippant. Evi-
dently he is interested to his subject, as he sometimes
rises almost to enthusiasm. We have chapters on
the folk-lore of plants, birds, animals, insects, and
reptiles ; the moon (a fruitful source of old-world
sayings) ; besides half a volume relating to birth,
death, marriage, &c.
MICROSCOPY.
The Congress of Microscopists, held at
Indianapolis, Ind., August 14th, 15th, 16th, and
17th, was a great success as regards numbers pre-
sent and results arrived at. Delegates were in
attendance from all parts of the Union, sixteen
societies being represented by delegates. Many
papers of value to the working microscopist were
read. Amateurs had ample opportunity to profit by
the work of older workers. Results were compared,
and many delightful acquaintances formed. Dr. R. H.
Ward, of Troy, N.Y., was elected President, and Mr.
II. F. Atwood, of Chicago, Secretary. One evening
was devoted to a "conversazione," at which the
public attended, and were duly pleased with the
popular slides which were chosen for their entertain-
HARDWICKE'S SCIENCE-GOSSIP.
■57
ment. Perhaps the most enjoyable part of the meet-
ing were the "seances," held each evening in the
various rooms in the hotel. No such gathering of
microscopists could come together and not bring
about a discussion on "Angular Aperture"; high
and low angles were both well represented, the former
by such well-known authorities as Prof. J. Edwards
Smith and Dr. Geo. E. Blackham, while Prof.
Romyn Hitchcock, of New York, supported the
latter. While the question will remain an open one
for long time yet to come, it is but fair to say that
many gentlemen who had always used low-angled
lenses prior to the meeting, went away essentially
high-angled men. Several of the American dealers
made fine displays of microscopes and objectives.
Of the English manufacturers, Beck & Crouch were
fully represented through their respective American
agents. Before the congress adjourned, the " Ame-
rican Society of Microscopists " was formed, Pres.,
Dr. R. H. Ward, Troy, N.Y. ; Sec, Henry
Jameson, Indianapolis, Ind. ; Treas., H. F. Atwood,
Chicago, 111. The next meeting of the new society
is to be held in August, 1879, at Buffalo, N.Y., and
from its auspicious beginning, and the enthusiasm
manifested by its members, it is fair to predict that
the future meetings will be of more than ordinary
interest.
Microscopical Society of Liverpool. — The
seventh ordinary meeting of this society was held at
the Royal Institution, on Friday, the I Ith October.
After the ordinary preliminary business, a paper was
lead on "The Life History of a hitherto Unrecorded
Septic Organism"; with drawings from life; illus-
trated by means of the Oxy-hydrogen Lantern, by
Rev. W. II. Dallinger, F.I?. M.S. At the conclu-
sion of the meeting a conversazione was held, when
the following subjects were illustrated : — "Alga?,
Marine," T. C. Ryley ; "Carchesium Polypinum,"
natural state, mounted, Isaac C. Thompson; "Dia-
toms," Charles Symes, Ph. D. ; " Durio Zibetha-
rinus, — decolorized leaf of from Borneo," polari-
scope, the President; " Oscillatoria," mounted slides
and alive, the President; "Polyxenes lagurus," Rev.
W. H. Dallinger, F.R.M.S. ; "Pond Life," George
Thomas; " Section of Wigan Coal," John H. Day ;
" Spores of Fungi," Rev. W. Bannister.
A Remarkable Photograph. — The "American
Journal of Microscopy" for August, 1878, describes
a marvel of photographic manipulation in the form
of a micro-photo of the Lord's Prayer. Our readers
are well acquainted with the ordinary micro-photo-
graphs of engravings, &c, and for which a power of
30 diameters is usually the extreme limit of amplifi-
cation which can be used effectively, the higher
powers destroying the sharpness of the outline. The
above-mentioned photo is only y^ of an inch square,
01" tttuotx °f a square inch (one of the squares in
Maltwood's finder would contain it four times), and
will bear inspection with \ objective and B ocular-
These slides are the production of Mr. Langenhcim
(of New York ?).
ZOOLOGY.
Marine Dredging. —I have collected for years
on the Lancashire and North Welch coasts, and I
thought I should like to try a fresh locality. Know-
ing the ruggedness of the coast scenery of the Isle of
Man, I proposed making that place the theatre of
my operations, and I can certainly say I never saw
happier hunting-grounds for the naturalist. Ane-
mones by thousands, Algce, Red, Brown, and Green,
in wonderful profusion ; in fact, almost every depart-
ment of Marine Zoology is well represented. I was
enchanted, and determined that next year, if spared,
I should devote a week or so to collecting. A friend
of mine who brought some anemones back with him,
sent for me to name them for him. Among a lot of
Actinia mesembryanthemum, Tcalia crassicornis,
Aiilhea cercus, &c., I found one I had not previously
seen, but which I had no difficulty in recognizing as
Bnnodes gonmacea (the Gem Pimplet of Gosse). It
is a charming animal, well worthy of its name. It is
still alive and healthy, having had two feeds of
mussel. The only locality Gosse gives for this
anemone is "the south-western and southern shores
of England and Ireland, on exposed rocks and shallow
pools between tide-marks." If this locality is new, I
gladly record it for the benefit of brother naturalists.
It is not uncommon even in Douglas Bay. In answer
to " C. E. R.," I may say this anemone requires no
peculiar treatment. It is easy to keep alive if the
aquarium is in good condition ; also, the best method
of feeding baby anemones is to let them feed them-
selves, and they'll not starve. In fact, none of the
animals in a large tank I had were fed for twelve
months, and I can aver that there were no deaths,
and the whole affair required less looking after. I am
much obliged to " H. C. C. M." for description and
figure of Tangle-dredge. I have no doubt it will be
a very useful instrument to the marine zoologist. I
was very sorry to hear of his want of success, but can
readily divine the cause. Since the establishment of
public aquaria there has sprung up at various parts of
the coast quite an army of collectors. The locality
he mentions is very familiar to me, having collected
on its shores and dredged in its deep waters many
times. The channel in the straits (north entrance) is
very narrow, and runs close to the Anglesea shore,
but my boatman took me to dredge on the low banks
of mud, which I knew were exposed every tide, and
it was only on showing him I knew better that I got
my dredge down on prolific ground. I have tried
many times to procure a "Ball's Naturalists' Dredge,"
but have as yet been unsuccessful ; none of the
London fishing-tackle-makers know anything about

it. Could you or any of your numerous readers tell
me where I could get it ? — J. E. Lord, Rawtenstall.
A Seal in a Trap. — A seal has recently been
engaged in exploring the interior of Suffolk. It
ventured up a dyke near Leistbn, in Suffolk, and was
shot whilst lying there. As one might have expected,
it was a young animal, weighing just thirty pounds,
and measuring forty-one inches in absolute length.
Living Beetles as Female Ornaments. —
We hope the attempts to introduce living exotic beetles
as female ornaments will fail, if only in the interest of
the animals themselves. We read in a fashionable
newspaper of one which has been adorning a lady's
shoulders for six weeks, and subsisting for that period
without food ! The lady did not know (and probably
did not care) how long it had been without food
before she had it ; and as it came from central America,
it may have been some time. Are we so hard up for
ornaments that we must resort to these aboriginal
customs ? They are understandable in the case of
those African beauties who are obliged to dispense
with any other dress, but we have not quite retro-
graded to that condition.
" Science Made Easy." — Under this title Mr.
Thomas Twining has issued a series of six familiar lec-
tures on all kinds of scientific subjects, but chiefly those
bearing on economic industries. They are issued
in shilling parts by Hardwicke & Bogue, 192, Picca-
dilly. The type is large, and pleasant to the reader's
eyes ; the illustrations of the very best and most
effective kind. Science teachers and others interested
in the spread of scientific education will find these
"Lectures " invaluable. We should like to see them
used in every Board School in the kingdom, and we
would strongly advise such of our readers as are con-
nected with those institutions, either as managers or
committee, at once to obtain copies of these lectures,
and endeavour by their means to lay that foundation
of scientific instruction which to England, more than
any other country, is absolutely indispensable.
Popular Science. — The Popular Science Revieio
for October contains articles on "The Sand and
Brittle Stars," by Professor Martin Duncan ; " Coal
and Colliery Accidents," by Mr. C. De Ranee,
F. G. S. ; " The Radiolaria as an order of Protozoans,"
by Dr. Wallich ; "The Eucalyptus globulus," by
M. Betham Edwards ; and on "The Extinct British
Wolf," by J. E. Harting, F.Z.S.
Rare Birds. — From various paragraphs in last
month's Zoologist we gather that the Hoopoe has been
unusually abundant this year on the south and south-
western coasts. Observers mention it as being seen
at Chichester, in the Isle of Wight, and near the
Land's End. It has also been seen near Gloucester.
As one might expect, in most places the beautiful
stranger was shot! Perhaps in time natural selection
will endow rare birds with more sense than to approach
the English coasts.
Provincial Natural History. — We have re-
ceived a copy of Part 4, vol. ii., of the " Transactions
of the Norfolk and Norwich Naturalists' Society,"
containing a most able address by the President, Mr.
F. W. Harmer, F.G. S., which deals chiefly with the
difficulties of the Darwinian theory, and is a capital
defence of it against some recent attacks. It also
contains papers on the Norwich crag, by Mr. Harmer ;
a list of plants found near Cromer, by Professor
Babington ; letters relating to the Natural History of
Norfolk, by Mrs. R. Lubbock and Professor A.
Newton ; on William Arderon, an old Norwich
Naturalist, by F. Kitton ; notes on Norfolk Mam-
malia, by F. Norgate ; Meteorological Notes, by
John Quinton, jun. ; Ornithological Notes, by H.
Stevenson ; and Heteroptera and Homoptera of
Norfolk, by J. Edwards. The "Report of Proceed-
ings" of the Norwich " Science Gossip Club " has
also been forwarded to us, containing an abstract of
all the papers read last winter, embracing a variety
of scientific subjects, all ably and intelligently
treated, together with the Address of the President,
Mr. S. C. Sothern. This is a very popular society;
and one which those young naturalists would do well
to correspond with who wish to found an unpretending
science club. Part 10 of vol. i. of the " Transactions
of the Watford Natural History Society " is also to
hand, containing index, list of members, Sec.
The Kingfisher in London. — On Monday,
30th September, when crossing Westminster Bridge,
I was surprised to see a kingfisher fly across the
Thames from the Houses of Parliament towards St.
Thomas's Hospital, and then cross the bridge and
fly down the river. It seemed at a loss to know
where to settle. I see by the Standard it has been
noticed lately in the Serpentine. — J. L. Hawkins.
The Bottle-head Whale. — On the 31st August
I wrote a letter to the editor of Chambers's Journal
respecting the capture of a cetacean. It happened
on the 22nd ult. near Nice. He advised me to for-
ward to you the drawing and description of the
same. As to external appearance, this cetacean had
a great likeness to the Bottle-head, of which a de-
scription is given in Chambers's " Encyclopcedia,"
except that the surface of the body was all over
covered with narrow irregular white stripes ; but
when I went on the spot (three days after the capture)
they had almost disappeared. A more remarkable
difference between the two specimens lies in the skull,.
as you can judge from the adjoining drawing. Would
not this induce us to establish a new species ot Hyper-
obdon, contrary to the general opinion that there
exists one species only ? The total length of this
cetacean was 570 metres. It was driven ashore
alive, and was condemned to total destruction had I
not interfered. The skeleton has been so preserved
and brought to Nice. A similar, but not quite
identical specimen, was caught many years ago on
HARD W I CKE ' S S CI EN CE-GO SSI P.
259
our coast, and described by our naturalist Risso.
There were stripes on the body, as in the present one,
but the forehead was even more flat, and the dorsal
fin trapezoidal instead of triangular ; so, at any rate,
it was represented by a drawing. No description
was given of the skeleton. — Hippolyte de Pierlas, Nice.
BOTANY,
Alpine Flowers. — Hermann Midler writes to
Nature to say that in the Alps he has found some
instances of different forms of flowers in plants of
the same species, which, as far as he knows, have
been hitherto undescribed ; of which he gives a short
notice as follows : — Geranium sylvaticum is in one
locality near the Albula Pass gynodioecious, with
large-flowered hermaphrodite, and small-flowered
female stems. Veratmm album, Dryas oetopetala,
and Geum reptans are in all the localities where he
has examined them androdicecious. Astrantia minor
offers a quite peculiar sort of androdioecium, some
stems bearing, as in other Umbelliferce, in the same
umbel hermaphrodite flowers and male ones, other
stems producing solely male flowers. Dianthus
superbus seems at first sight to exist in three forms :
(1) Stems with hermaphrodite flowers, being per-
fectly proterandrous and producing a moderate quan-
tity of whitish pollen ; (2) stems with female flowers
containing very conspicuous rudiments of stamens,
but pollenless anthers ; (3) stems with pistils remain-
ing imperfectly developed, and with anthers con-
taining abundance of a brown powder. At first
sight H. Midler thought their flowers to be male, and
the brown powder to be pollen- grains ; but under
the microscope the latter proved to consist of grains,
the diameter of which is only about one-eighth of
that of the pollen-grains of the hermaphrodite flowers.
He supposes, therefore, these grains to be the spores
of some species of fungus, and Dianthus superbus
to be gynodioecious.
Vegetable Teratology. — The state of Plantago
.lanceolata in which the spike is replaced, surrounded
■or surmounted by a tuft of leaves, appears to be very
plentiful this season, as I gathered no less than
thirteen such specimens, all growing in different
places, when taking a walk on August 16th. In
several of these the spike is surmounted by from two
to five leaves, while in others a second spike springs
from the centre of the leafy tuft. In one specimen
the rosette of leaves surmounting the stem is pretty
large, and ten spikes spring from its base, their stems
varying from half an inch to four inches in length,
and the whole forming a sort of irregular umbel.
The dry summer, succeeded by showers at the end of
July and beginning of August, has probably some-
thing to do with the unusual abundance of these
■curious aberrations. — D. Douglas, Leith.
Beeches and Hollies ; Oaks and Haw-
thorns.— A friend of mine tells me that about the
middle of September he was in the New Forest,
where he noticed that beneath the large beech-trees
there was an abundant under-growth of hollies, but
no hawthorns, whereas under the oaks there was an
abundant growth of hawthorns, but no hollies. I
should be glad to have an explanation of this. — R. H.
Alcock.
" Flowerless Plants." — Under this title Dr.
Franklin Parsons has contributed two most readable
articles in the recent numbers of The Naturalist,
which, as our readers are aware, is the journal of the
Yorkshire Naturalists' Union, and their general field
club record. Some time ago we heard a whisper
that The Naturalist would have to be discontinued
for lack of support. We sincerely hope our York-
shire friends will not allow such a stigma to fall on
their hearty and generous county.
Vegetable Moth-trap. — Mr. W. Simpson, of
Dartmouth, has described a large plant of Physianthus
albicans, belonging to the Asclepiadce, which flowers
there in the autumn very profusely. He says it is
one of the most deadly moth-traps he knows. Many
days running he found from two to eight Humming-
bird Hawk-moths caught by their probosces in the
flowers, where they died in about two minutes.
Other insects were also found dead in the flowers.
The plant is of trailing habits, and easily trained
over porches. Have any of our correspondents
noticed its insecticide habits ?
European Fungi. — All botanists will be rejoiced
to hear that Dr. M. C. Cooke, A.L.S., and Mons.
L. Quelet, M.D., have written conjointly a work,
entitled " Clavis Synoptica Hymenomycetum Euro-
preum," which has been just published as a handsome
little volume by Messrs. Hardwicke & Bogue at 7s. 6d.
In this book every species of fungus heretofore found
in Europe is described in brief but excellent and
easily understandable Latin ; so that it is a work
which thus requests a world-wide circulation. The
high reputation of its authors as fungologists must
make the present work a hand-book to all botanists.
Double Flowers. — A few days ago we examined
the flowers of the common Petunia, and found the
stamens had developed into petals. Each, so-formed
petal was distinct, so that the internal structure was
thus polypetalous. We have noticed that whenever
the stamens are thus modified in gamopetalous flowers,
the newly-formed petals do not cohere. Does not
this indicate that polypetalous corollas must have
preceded the gamopetalous in the order of floral
evolution ?
"The Herefordshire Pomona." — Under this
title the first part, price 15s., has just been issued by
Messrs. Hardwicke & Bogue, of a most magnificent
work, containing coloured figures and descriptions of
the most esteemed kinds of apples and pears.

HARDWICKE'S SCIENCE -GOSSIP.
coloured plates are of the very highest degree of
excellence, and it is long since we have seen illustra-
tions of natural-history books so artistically executed.
There can be no doubt that this artistic superiority
will of itself give this much-needed work an extensive
circulation. It is edited by Dr. Robert Hogg, F.L.S.,
and is chaperoned, we believe, by the well-known
and energetic Woolhope Naturalists' Field Club.
The letter-press contains outline woodcuts of every
variety of apple aud pear in cultivation, besides other
engravings of high merit.

Monstrosity in the Daisy. — The above is an
illustration of median prolification occurring in a
specimen of the common Daisy [Bellis perennis) found
at Cobham. It occurs frequently in gamosepalous
and gamopetalous flowers, when it is known under
the term of "hose in hose," but we have never seen
it before in a composite flower.
GEOLOGY.
The late Mr. Thomas Celt, F.G.S. — It is
with much regret that we have to announce the death
of Mr. Thomas Belt, F.G.S., one of the most dis-
tinguished of the younger school of naturalists, who
died after a short illness, of rheumatic fever, at
Denver, United States, in the 46th year of his age.
He was a frequent and valued contributor to our
columns, and only a few weeks ago sent us the
account of his discovery of a human skull at Denver,
under circumstances indicating high antiquity. He
was the author of several works on natural history,
the best known of which is the "Naturalist in
Nicaragua."
What are Conodonts? — At a recent meeting
of the Natural History Society of Glasgow, Mr. John
Young, F.G.S., read some notes on a group of fossil
organisms termed Conodonts, which have recently
been discovered in the Carboniferous limestones of the
Ayrshire coal-field by Mr. John Smith, of the Eglintoia
Ironworks, Kilwinning. These organisms are minute,
slender, conical, tooth-like bodies of varying forms,
of a brownish colour, and having a glistening or
enamelled appearance ; few of them exceed an eighth
of an inch in length, many of them being much
smaller ; they are mostly of a comb-like form, being
serrated along one of the sides with a row of teeth,
often of unequal length and stoutness. Conodonts
were first brought under the notice of geologists by
Dr. Pander in 1856, in a work descriptive of the
fossil fishes of the Silurian formation in Russia, in
which country they are found ranging in strata from
the Upper Cambrian to the Carboniferous deposits.
In America they have also been discovered in the
Devonian and Carboniferous formations ; Professor
Newberry having figured and described a number of
Carboniferous forms in his work on the palaeontology
of Ohio. But until this discovery of Mr. Smith's, no
remains of Conodonts seem to have been noticed in the
strata of the several formations in Britain. Mr. Young
stated that he had recently the opportunity of sub-
mitting Mr. Smith's specimens to a Canadian palae-
ontologist, Mr. Jennings Hinde, while on a visit to
this country, and he stated that they were closely
related to the American forms, especially to those
described by Prof. Newberry. Although Conodonts
have now been known to palaeontologists for more
than twenty years, great doubts still exist as to what
group of animals these curious teeth-like organisms
belong. Dr. Pander, their first discoverer, thought
they were the teeth of a group of cyclostomatous
fishes allied to the present lampreys. Professor Owen
doubts their fish affinities very much, and says some
of them may be the dentated claws of small Crustacea ;
others may be the teeth booklets or denticle; of naked
mollusca or annelides. Professor Newberry thinks
Dr. Pander is right in referring them to fishes ; if so,
fish-life will have to be carried forward to a much
earlier period in the history of our globe (namely, the
Cambrian), no undoubted fish-remains being at present
recorded from strata older than the Upper Silurian.
These Conodonts are found in both the upper and
lower limestones of the Ayrshire coalfields; upwards
of thirty forms have already been discovered, and it
is probable the number may be increased by further
researches in the deposits. Along with the Cono-
donts, Mr. Smith has also found a new group of fossil
sponges, different from those of Hyalonema, which
he discovered last year in the Lower Limestone series
at Cunningham Pedland, near Dairy. The silicious
spicules of this new group of sponges from the Upper
Limestone are of various types, and Mr. Young stated
that at present the forms were being examined by
Professor Voting and himself, and they intended
bringing them up fit a future meeting. The same
deposit also contains an interesting group of small
forms of mollusca, in a fine state of preservation, many
of the univalve or spiral shells, having their mouths

quite entire, and several of them being of species not
formerly recorded from the Carboniferous strata of
the West of Scotland.
Perpendicular Holes in Rocks. — In a sec-
tion of what is, I believe, inferior oolite, underlying
sand at Manton Warren, near Kirton-in-Lindsey,
Lincolnshire, there are exposed to view perpendicular
holes of some ten inches in diameter, passing through
the successive layers of stones, and through the stones
themselves, as if bored. A depth of 5 ft. is exposed
to view, but how much deeper they go I do not know.
I observed three within a few feet of each other.
The diameter does not appear to decrease with the
depth. Will any one state the probable origin ?
Are they "pot-holes"? The stone obtained has been
broken up for roads. The warren is elevated above
the surrounding country. — J. Ar. £>., Tuxford.
A New Eocene Mammal. — A new genus of
pachydermatous mammals, nearly allied in its denti-
tion to Pakeotherinm, has been recently found in the
Lower Eocene beds of Transylvania. The fearful
generic name of Brachydiastematherium has been
given to this extinct creature.
A New Oolitic Pterodactyle. — Hitherto
no Pterodactyle remains have been found in America
of older date than the Cretaceous period. News
comes to us, however, of a species of Pterodactyle
which has just been found in the Oolitic rocks of
Wyoming, whose outspread wings must have been
five feet from tip to tip. It has been named P. mon-
tanns.
Geology of the American Lake Region.—
Mr. George Maw, F.G.S., writes as follows on this
subject : — " We must set aside the view that the
chain of large lochs is due to glacial excavation ; for
Ontario, the deepest of the lakes, running east and
west, is in lower latitude than Huron, the bottom of
which is 510 feet above that of Ontario ; and there is
no high ground about Ontario from which ice could
have originated as a preponderating mass, capable of
excavating Ontario 600 feet deep ; nor is there any mass
of debris anywhere to be seen about the lake as would
represent such an excavation."
NOTES AND QUERIES,
Water-Boatman. — Your readers, who are no
doubt familiar with the very savage instinct of this
insect, may be interested to learn my experience of
him. He really appears to be quite shark-like in his
nature. A few weeks since, whilst staying with some
friends in Cambridgeshire, to amuse the children I
collected from several ditches various Sticklebacks,
Whirligigs, Newts, a Frog, &c, and three Water-
Boatmen. These I thought might possibly make a
nice little "happy family"; but my hopes were
doomed, as the boatmen soon proved themselves to
be most formidable. Theyj attacked each of the
animals before-mentioned except the Whirligigs, whose
movements were too quick for them. After killing
the insects and Sticklebacks, one fastened himself to
the frog's leg.—//. Hall.
Laburnum Flowers.— Laburnum trees are in
blossom here now (September). Is not this an unu-
sual phenomenon? — R. II. Nisbet Browne, Folkestone.
Palm Roots. — With reference to the question
propounded in your issue for October, as to whether
palm-trees have tap-roots or not, 1 find, on consulting
the highest authorities in the library of the Linna:an
Society, that the roots are fibrous masses. Stephen
Endlicher, in his "Genera Plantarum," published in
1836-40, writes thus : — " Palm re Plantre liques-
centes, acrobryje habitu peculiari. Radix palaris,
mox evanida ; radicular plurima;, cylindrical, sim-
plices et ramose, fibrillosre, in inolem conicam saape
ex parte hypogream dense compactce." Loudon, in
his " Encyclopaedia of Plants," writes: — "The lofty
stems of palms are supported by a mass of fibrous
roots, which frequently cross along the surface of the
ground." In the " Horuis Indicus Malabaricus," by
Henry Van Rheede, published in 1628, the author
states that the Palm diffuses its root-fibres widely in a
transverse direction. With regard to the interpre-
tation of the verse of Psalm xcii., where the righteous
are compared to the vigour of the Palm-tree, it would
be presumptuous in me, as a layman, to offer an
opinion or discuss it in a theological point of view.
Canon Tristram, in his "Natural History of the
Bible," alludes to the 12th verse of the above Psalm :
' ' Here the life of the righteous may be compared to
the Palm-tree for many reasons. It flourishes in a
barren soil ; it requires constant moisture ; it is a
lofty tree, a straight tree ; it is always growing so
long as it lives, and it is always green, and always
bears fruit as far as possible from earth, and as near
as possible to heaven. We may add, too, the elas-
ticity and upward growth of its fibre, even when
loaded with weight." The following is extracted
from Mr. Hooker's translation of Le Maout et
Decaisne: — " Palms, perennial woody plants, elegant
or majestic in habit. Primary root decaying early
and replaced by numerous adventitious roots, which
are developed at the base of the trunk, and form a
compact conical mass, often very voluminous and
rising more or less above the soil, and in certain
cases raising the trunk and supporting it like the
shrouds of a ship." The Palm-trees with which I was
most familiar in India were the Cocoa-nut and Date.
Neither had tap-roots. Professor Bentley, in his
"Manual of Botany," writes: "The true or pri-
mary root, from its being formed by a direct elongation
of the radicle, generally continues to grow downwards
for some time at least, and hence forms a main trunk
or axis from which the branches are given off. Such
a root is termed a tap-root, and may be commonly
observed in dicotyledonous plants. On the contrary,
the roots of monocotyledonous and acotyledonous
plants, wbich are adventitious, are usually of nearly
equal size, and given off in variable numbers from
the radicle." The above remarks will, I think, show
that the palms do not possess tap-roots. — John
Colebrook.
Roots of Palm-tree. — There are several kinds
of trees called Palm, and the first question to be
settled should be, Which is the Palm-tree of the
Bible ? Many are of opinion that it is the Phcvnix
doxtylifera, or Date-palm, which affords food to
both man and animals ; and I will, therefore, give
you a short description of the Palm met with by
Bonar in the desert of Sinai. He says : " The roots
262
HARD JVI CKE'S S C1ENCE- G O SSI P.
are unlike any other tree-roots we had seen, and
peculiarly fitted to absorb every drop of moisture
that the sand contains. In general form and structure
they put us in mind of the Dahlia and Ranunculus,
consisting of long fleshy strings or ropes, shooting
straight down into the soil in numbers quite beyond
our reckoning, and extending over a large circle,
whose width we could not ascertain." Again, the
same writer observes: "What an apparatus for
drawing up the moisture of the desert." The roots
of all the Palmacea are described as fibrous : no
matter what the form may be, or the size of the
stem, it is invariably woody, and the roots fibrous.
This is the sum and substance of all I have been able
to call to mind as having read of the Palm-tree ; but
many who are better versed in the matter will reply
to "A. B.'s" question. — Helen E. Watney.
Cat and Rabbits. — A curious case of the adop-
tion by a cat of some rabbits has come under my
notice. The mother of the rabbits died, and the
kittens having been destroyed, the cat suckled the
rabbits and brought them up. This occurred in a
small village in Surrey. May not this throw some
light on the story of Romulus and Remus being
suckled by a wolf, supposed by historical research
to be fabulous ? — H. P. Barclay.
Egg Drills. — Beta will be able to obtain the
instruments described in my article on collecting
birds' eggs, of Mr. J. Everard, surgical instrument
maker, 34, Berners-street, W. — T. Southwell.
Marsh Tit. — In answer to " C. C.'s" question
(Science-Gossip, page 234) "as to whether the
curious note, resembling the whetting of a saw,
belongs to the Marsh Tit," it is certainly not the
Marsh Tit, Parus palnstris, because that peculiar
note is heard in situations where the Marsh Tit is
not found. We believe the note to belong to the
Great Tit, Parus major. The song is heard as
early as January, often from the top of a high tree.
The bird is very remarkable from the similarity of
the simple note to the sound made in filing a saw.
Hence, in Staffordshire, the bird is commonly called
" Saw-whetter. " — Elizabeth Edwards.
Migrating Birds. — Last Sunday I heard, about
eight o'clock p.m. the whistling of innumerable
birds, passing over Northallerton in a south-westerly
direction. I presume them to have been a flock of
plovers. They continued to pass over until eleven
o'clock. Are these birds regular migrators, or does the
present case betoken the approach of a severe winter ?
—J. A. Wheldon.
Sea Anemones.— " C. E. R." will be glad to
learn that I kept two of Bitnodes gemmacea for the
greater part of a year, and might have done so for a
longer period, as they were still in first-rate condition
when the accident occurred which caused their death.
I kept them in a glass bottle of about six inches
diameter, with a loosely-fitting stopper always on,
and they were fed twice a week with bits of shrimp,
such as one buys at the fishmonger's. I find that small
and delicate sorts do well in these bottles ; the glass
stopper prevents evaporation. Small plants appear
quickly all over the sides, and altogether they are
the most self-compensating aquaria which I know.
I have kept them for long periods without diminution
of the contents, and consequently without having the
water more dense than at first. Will " C. E. R." be
good enough to describe his treatment of Tealia crassi-
cornis ? I have read, and have been told on good
authority, that it is impossible to keep it. My
attempts have always failed ; but, owing to circum-
stances, I have been unable to obtain one of which I
could say with certainty that the base had not been
injured. — IV. G. H. C, Frome.
Zoological Notes. — There was shot on theTees^
on the 30th September a female Great Northern
Diver {Co/ymbits artiais), also a Stormy Petrel (P/ocel-
laria pelaqica). Two swans were also shot, and are
now in the hands of Mr. Richardson, of this town,
for preservation. During the last fortnight large
flocks of Wild Duck, Teal, Widgeon, &c, have been
passing on their autumnal migration; several large flocks-
of geese have been seen passing over the Cleveland
Hills. A Death's-head Moth was also captured at
the end of September. — George Simpson, Middlesbro',
October 6th.
The Song Thrush and Blackbird Pairing.
— In confirmation of Mr. Robert Holland's article in
Science-Gossip of June, on "Remarkable Nests,"
it might be well to insert the following well-authen-
ticated instance. In the island of Howth my
daughter saw a cock blackbird sitting on a nest where
previously a hen thrush had been sitting. There
were young ones in the nest, which was not lined.
There can be no doubt as to identity, as it was re-
marked by others. — S. A. Brenan, Clk., Allan Rock,
Co. Tyrone.
Songs of Birds, &c. — A work on the songs of
birds and other animals as related to human music,
and as furnishing a basis for a theory of melody, has
occupied me two years. The chief impediment is the
lack of received observations. I should be most
grateful if you kindly assist me in any of these ways,
viz. : — I. Reference to books, &c, containing songs of
birds or other animals in musical notation. (Cqpies
of these would be still more valuable.) 2. Results of
your observations on bird or other songs. 3. Is
there noticed with any frequency in these songs the
occurrence of any fundamental intervals of human
music, — as the octave, fifth, fourth, and third ? '
4. (A question only seemingly irrelevant) — If sing-
ing in the ears has ever happened to you, have
any of the fundamental intervals above mentioned
been observed between the minute tones ? 5. Any
information that may occur to you as bearing on these
subjects. All contributions will be acknowledged,
and the results sent to you on publication. — 916,
Washington Street, San Erancisco, Cal.
Parasites on Birds. — Are there any means of
destroying the parasites on fantail pigeons ? The fan-
tails are kept in a large open room at the top of the
house, with the window constantly open, so that they
fly in and out at pleasure. The parasite which most
infests them is about the eighth of an inch long, dark
in colour, very slender in proportion to its length, so
that to an ordinary observer it hardly appears to be
an insect ; there is also another, round in shape,
perhaps one-sixteenth of an inch in diameter, and
pinky in colour. The birds have fresh water every
day for bathing. Is there any danger of the creatures-
forsaking the bird for the human habitants of the
house, as the pigeons are very tame, and perch on
head or shoulder ? And will the Editor kindly tell
Mrs. Geveke if there is any sensible reason why
pigeon feathers should not be used for stuffing pillows,
&C.—AI. G.
Palms at Shanghai (page 178). — Your corre-
spondent, Mr. Nelson, calls attention to the fact ot
Palms enduring frost and snow at Shanghai with im-
punity. Judging from the short and negative descrip-
tion which he gives, viz., that they are not "as
HA R D WI CA'E' S S CTENCE - G 0 SSIP.
263
graceful as the lofty Cocoa-nut trees of Ceylon, or
the Sago-palm of Borneo," I am inclined to think
that the species to which he alludes is Fortune's
Chamrerops, which is an inhabitant of the cooler
portions of China, and one or two specimens of
which might be seen, a few years ago, growing in the
open air at Kew. But the general question of
acclimatization is one well deserving the attention of
botanists and florists. If all plants that are uninjured
by frost or snow in their own country could be
guaranteed to be equally hardy in England, the
matter of acclimatization would be very simple. Our
shrubberies, and heaths, and hedgerows would be
enlivened with many a bright gem from Canada,
Switzerland, and the mountainous portions of hotter
lands. I have lately returned from a sojourn in
Tasmania, and there, every winter, the lovely Fern-
trees, which abound in the mountain gullies, are
weighed down with snow ; and quaint Gums
{Eucalypti) and feathery Wattles {Acacia) nourish in
a temperature rivalling in coolness that found in many
parts of England. But nothing is more certain than
that neither Fern-tree, Gum, nor Wattle will exist in
Great Britain, except in one or two favoured situa-
tions. The reason of this apparent paradox is not
far to seek. The incapability of these foreigners
to bear the severity of an English winter is simply
due to the difference between their respective sum-
mers. In the countries named, during the summer
months, there is an almost continuous outpouring of
the sun's actinic rays, thoroughly ripening the wood,
and giving life and vigour to the contained fluids,
while, at the same time, the atmosphere is com-
paratively dry, and the air is not eternally loaded
with superabundant moisture. We all know how
different from this is the normal condition of the
English summer. We certainly get the advantage in
the greenness of our meadows and the fresh appear-
ance of our vegetation, aspects for the most part
unknown in the countries alluded to ; but the in-
cessant humidity, and the general absence of sunlight,
are fatal to the well-being of plants which in other
lands, thanks to the summer solar ray, can defy the
frost and snow of winter. A very careful selection
might add a few foreign names to our native species ;
but before Palms and Fern-trees grace our land-
scapes, the theory of "heredity" must be worked
out patiently and slowly, and then possibly the
"survival of the fittest" may take place. — IV. W.
Spicer.
Clams. — I have tasted clam soup in America.
It is somewhat like oyster soup, but I believe it is
made, not from the giant-clam, Claina gigas, but
from the soft clam of the northern shores, the Mya
arenaria, which is very much used in America as an
article of food. It is found in great abundance on
the coast of New England, and makes good bait in
cod and haddock fishing. The shells are dug up
from thin beds at low water. They are found a foot or
so deep below the surface, their siphon-tube projecting
upward in the hole by which they communicate with
the water at high tide. They are " shucked," that is
taken out of their shells, and salted for the fisheries.
As many as five thousand barrels a season are thus
consigned. Clams are often mentioned in the early
history of the Plymouth colony; and judging from
scalloped clams, roasted clams, and clam soup, I
have no doubt but what Mr. W. A. Cairns will find
preserved clams very fair eating for persons who
rejoice in a good digestion. — H. E. Watney.
A Mysterious Gift. — An account of the first
ascent of the Peter Botte Mountain is given in the
Penny I\ fa gazine for 1833, which is probably the one
referred to by your

fraga stellaris.
Young Muscologist.— Get Hobkirk's " Synopsis of British
Mosses," price 10s. 6d., published by Lovell Reeve.
A. Bernard. — The curious monstrosity of the stems of the
Malva moschata (which we are much obliged to you for
sending us) is described by Dr. Masters in his " Vegetable
Teratology" by the name oi fasciculation. It is caused by
the abnormal growing together of branches, just as the normal
substance we call "horn" is due to the agglutination of hairs.
J. Sims. — Of course we are obliged to trust to the honour
of those who use our exchange column, and we cannot be
expected to guarantee good faith. We shall always feel
obliged if " exchangers " will notify to us any breach of faith.
We shall then take good care to exclude the offenders for the
future.
A Young Geologist. — Your fossils are : — 1. Pcctunculus
glycimeris (young specimen) ; 2. Fragment of Natica ; 3.
Purpura lapillus. The crystals are selenite, or sulphate of
lime, derived from the London clay. See chapter in Taylor's
" Geological Stories," entitled " Story of the Crags."
J. K. (Yarmouth). — Trimmer's "Flora of Norfolk" is a
well-known and highly esteemed work. (2) We have not heard
of any recent numbers of Donkin's " British Diatomacese "
being issued ; nor can we guess the cause of the delay, unless
it be the author's professional engagements. Your plants are
named correctly in the parcel sent us.
J. Kirdy. — You may get the materials mentioned in Dr.
Woodward's process for staining muscular tissues from any
first-rate chemist.
W. J. R. — Write to Mr. Van Voorst, publisher, who has (we
believe) published lists for labelling, such as you require.
J. Anderson, jun. — The Fuchsia with the calyx segment
transformed into a green veined leaf is very curious, and very
instructive as an illustration of reversion.
J. W. N. — The slide contains elytra, &c. of the female of
the common water-beetle {Dyticus margi?ialis). The female
is so unlike the male in appearance that it was formerly re-
garded as a different species.
A. Wheldon. —Thanks for your monstrosity of Plantago
lanceolatum, showing three heads on one stalk.
K. D. — Will you kindly send us your query again, as we
have mislaid it.
G. R. Redgrave. — The malformed rose with mass of
petals arranged around the stem beneath the main mass is a

FEW years ago, being
anxious to apply Mr.
Sorby's method to the
granites and granitoid
rocks of the lake-
country, I examined a
number of slices of the
granite rocks, and mea-
sured nearly fivehundred
cases of liquid-cavities,
ascertaining the relative
size of the vacuity (or bubble) to the liquid-cavity. My
method of proceeding I will describe directly, but I
will at once state that the result arrived at in the
case of the Skiddaw granite, for example, was, that
its consolidation took place under a pressure of rather
more than an equivalent of 51,000 ft. of rock, and
that the mean pressure under which all the principal
granitic and granitoid rocks were consolidated was
equivalent to that of 44,000 ft. of rock.
My experiences in the course of this investigation
may be of interest to some who wish to undertake
original work of a similar kind. (For the Memoir
containing the investigation as a whole see Quar-
terly Journal of the Geological Society, vol. xxxi.,
p. 568.)
The object-glass generally used was a i-in. (of
Collins), with a C eye-piece, the combination magni-
fying 665 times. When I first began my measure-
ments I used a neutral-tint glass reflector, and traced
on paper all the best-defined fluid-cavities, making a
note by the side of those in which the vacuities
showed a constant spontaneous movement. I soon
found, however, that on a comparison of a consider-
able number of drawings, the fixed bubbles were
almost invariably relatively larger than those which
showed this free movement. Hence I was led al-
together to reject from my measurements all cases in
which the bubble was fixed, and in which it would
seem either that gas had been primarily entrapped,
No. 1 68.
or that in the making of the thin slice leakage had
occurred in the cavity. This last case must neces-
sarily often occur in the making of thin slices, espe-
cially as the liquid-bearing cavities are frequently so
irregular in shape and prolonged into horns and
fine points. I then gave up tracing the outlines of
cavities on paper, and measured the relative size
of bubble and liquid-cavity directly by means of a
Jackson's micrometer, with divisions equal to Too00th
of an inch. This micrometer being placed in the
eye-piece, the fine divisions could be brought over
the bubble and liquid-cavity, and their relative size
at once estimated with tolerable accuracy. But a
little consideration will make it evident that measure-
ment of a liquid-cavity in one plane would be of
little use unless the cavity be exceedingly shallow
and lie along that plane. Hence it became neces-
sary to take this further precaution, viz., to rely only
upon the measurements of those cases in which the
tiny bubble (or vacuity) moved freely into all parts ot
the liquid-cavity without going out of focus ; this
would imply that the cavity was of tolerably uniform
depth, but little more than the depth of the diameter
of the bubble. And it was found that, when I
restricted my measurements to these cases, there was
a fairly-marked uniformity in the ratio between
vacuities and liquid-cavities occurring in the quartz of
the same rock.
Thus, take as an example two different rock-slices
of the same granite

HARD WICKE 'S SCTENCE-G OSSIP.
In No. I there are five cases in which the whole
liquid-cavity is 6J times the size of the vacuity, one
case in which it is six times the size, and two cases in
which it is only 5J times. The mean '162 is pro-
bably not far from the truth.
It maybe difficult to realize the size of these liquid-
cavities and their contained bubbles. Those reliable
for measurement are extremely small, sometimes less
^th of an inch in diameter. Much larger
than T
cavities generally occur in plenty ; but these seldom
exceed the -j-oWth of an inch in length, and in them
the bubbles either have no movement, or but a very
slight or sluggish one. In fact, such is the minuteness
of these cavities and their number, in many cases,
that more than a thousand million might be contained
easily within a cubic inch of quartz, and sometimes
the contained water must make up at least 5 per cent,
of the volume of the containing quartz. In some
cases the liquid-cavities are much arranged along
lines, as in the quartz crystals occurring in the
ArmbothDyke. Occasionally, however, liquid-cavi-
ties are met with in quartz crystals of veiy considerable
size, such that the movement of the bubble can even
be recognized by the naked eye. Having accumu-
lated a sufficient number of reliable measurements,
and struck the mean for any one rock, such as the
Skiddaw granite, the calculation of the pressure
under which the granite was formed is proceeded upon
by mathematical formulae furnished by Mr. Sorby's
investigations, the temperature of a dull red heat
visible in the dark (68o° F.) being assumed as the
probable temperature of consolidation. The result,
in the case of the Skiddaw granite, is that a pressure
equivalent to 52,000 ft. of rock must have been
necessary to compress the liquid so that it would fill
the cavities at a temperature of dull red heat.
The next question bearing upon this result is one
for the field-geologist alone to determine. What is
the greatest thickness of rock which can have been
removed from over the mass of the Skiddaw granite
as we now see it exposed ? Geological investigation
cf the whole district leads me to infer that at one
time the granite must have been covered by some
30,000 feet of rock — including Skiddaw slates, vol-
canic series, and Upper Silurians. But we have seen
that the calculated pressure is equivalent to 52,000 ft.,
hence the pressure to which the consolidating granite
(and therefore quartz) was subject was greater than
what could be due to the mere weight of overlying
rocks. How, then, was this pressure applied ? We
have seen that the condensed liquid confined within
the quartz has remained as a registering thermometer,
to show the existence and amount of the pressure,
and geological examination of the district further
informs us that the overlying 30,000 ft. of rock was
in some way elevated and contorted, — being also
slowly removed by denudation. Thus we have
physical evidence, from two different sources, of the
existence of great pressure exerted upon the granite-
forming mass ; evidence derived from the liquid-
cavities and their contained bubbles, and evidence in
the rocks overlying the granite of such pressure having
produced elevation, contortion, cleavage, and general
metamorphism. It is further interesting to notice
what would be the probable heat at a depth of
30,000 ft. according to our estimates of known
increase on descending through the crust of our globe.
If we take that increase as 1° F. for every 49 ft.
(Mr. R. W. Fox, Brit. Assoc. Report, 1857, p. 91),
we find that at a depth of 30,900 ft. the temperature
would be 3600 C. (6800 F.), or that of a dull red heat
visible in the dark, and just the temperature at which
we were supposing the granite was formed. Thus,
to sum up our results in the case of the Skiddaw
granite : —
1st. It is probable from geological evidence that
this granite was consolidated at a depth of about
30,000 ft.
2nd. An increase of i° for every 49 ft. on descend-
ing gives a temperature of 3600 C. (6800 F.) at a
depth of 30,900 ft.
3rd. Microscopic evidence, deduced from examina-
tion of the liquid- cavities in the quartz, gives a
calculated pressure under which the quartz was con-
solidated at a temperature of 3600 C. (6800 F.),
equivalent to 52,000 ft. of rock.
4th. As the calculated pressure thus far exceeds
(by 22,000 ft.) that due to the estimated thickness of
overlying beds, or, what is the same thing, to the
estimated depth at which the granite formation took
place, it follows that there must have been a great
amount of available pressure to be exerted upon the
rocky crust around, and hence we find evidences of
folding and contortion of the rocks, and of their up-
heaval and general metamorphism around the granitic
area.
The case of the Skiddaw granite will suffice as an
example of this mode of treatment. I have elsewhere
{Quart. Joum. Geol. Soc, vol. xxxi., p. 568) treated
all the other granitoid rocks of the Lake District in
the same way, and with very similar general results.
There are yet, however, one or two points I should
like to call attention to.
The first of these~is the general absence among the
liquid-cavities in the quartz of Lake District rocks of
crystals of various salts, such as have been found in
plenty in some other districts. Are we to infer from
this that the liquid enclosed at the period of the for-
mation of the granites was less saline than in some
other cases ? Or is impossible that a more extended
investigation would make it appear otherwise ?
Another thing worth noting is the general absence,
as far as I have been able'to judge, of cavities in the
quartz containing, not water, but liquid carbonic
acid, which in some other rocks and other districts
are not infrequent.
While thus calling attention to various points con-
nected with the formation of quartz-be aring rocks of
HARD Wl CKE 'S S CIENCE - G OSSIP.

the district, I am far from claiming to have examined
into the question exhaustively, and would gladly see
other workers take up the subjectmore completely,and
either prove or disprove the results already obtained.
It is evident that microscopic examination throws
light not only upon the origin of such quartz-bearing
rocks as granite, but also upon that of quartz as an
accidental and accessory mineral among rocks, and
upon the mode of formation of quartz veins. We
are, in fact, led to see that heated water containing
silica in solution has played a most important part in
geological history, that such water has sometimes
been diffused through a rocky magma at a dull red
heat, under enormous pressure, and finally become
entrapped in millions of minute cavities in the solidi-
fied rock ; sometimes it has worked its way up along
cracks and fissures, and deposited quartz in those
fissures, forming veins ; sometimes circulating
throughout the mass of a rock, it has deposited the
quartz in all irregular cavities or vesicles, at a less
degree of temperature ; and finally we recognise the
same heated water fully charged with silica rising to
the surface in the form of the geysers of Iceland, and
playing a large part in all volcanic outbursts. Surely
there can be few thoughts more surprising than this,
that every piece of granite we pick up contains in its
quartz particles thousands of minute liquid-cavities,
and, moreover, that every such liquid-cavity in-
cludes a tiny vacuous bubble in constant tremor or
active motion, such motion, it would seem, having
been kept up for the countless ages since the granite
was first solidified deep down in the bowels of the
earth. Truly, we learn great things from study of
the most minute.
NATURAL HISTORY IN THE
SEVENTEENTH CENTURY.
By F. Kitton, Hon. F.R.1VLS., &c.
Part III.
THE first part of the treatise is devoted to hunting-
dogs — CanesVenatici. "But because we English
men make a difference between hunting and fowling,
for they are called by these seuerall words Venati and
Aucnpium, so they term the dog who they vse in these
sundry games by divers names, as those which serue
for the beast are called Venatici, the other which are
vsed for the fowl are called Anciipat&rij. The first
called Venatici I deuide into fiue sorts, the first in
perfect smelling, the second in quicke spying, the
third in swiftnes and quicknes, the fourth in smelling
and nimblenes, the fift in subtility and deceitfulnes,
herein these fiue sorts excelleth."
The description of each kind of dog is preceded by
the derivation of its name, of which we give some
examples.
"Of the Dogge called a Terrar, in
Latine Terrarius.
" Those whom we call Terrars, because they (after
the maner and custom of Ferrets in searching for
Connies) creep into the" ground, and by that meanes
make afraid, nippe, and bite the Foxe and the Badger
in such sort that they either teare them in peeces with
their teeth, being in the bosom of the earth .... or at
least through conceived feare drive them out of their
hollowe harbours, in so much that they are compelled
to prepare speedy flight, and being desirous of the
next (albeit not the safest refuge), are at leisvre taken
and intrapped with snares and nets laide ouer holes
to the same purpose.
" Of gentle Dogges semitig the hauke and first
of the Spaniell called in Latine Hispaniolus.
' ' The common sort of people call them by one gene-
ral word, namely Spaniels, as though these kind of
dogs came originally and first out of Spaine.
" There is also at this day among vs a new kinde of
Dog brought out of France (for we Englishmen are
marueilous greedy gaping gluttons after noueltiesand
couetous cormarants of thinges that be seldome, rare,
strange, and hard to get.) And they be speckled
al ouer with white and black, which mingled
coulores incline to a marble bleu, which beautifieth
their skins and affordeth a seemely show of comlinesse.
These are French dogs, as is aboue declared already."
The treatise concludes with remarks on the diseases
of dogs and their remedies, of which one specimen
will suffice.
" If a dog grow lean, and not through want of meat,
it is good to fill him, twice or thrice with Butter ;.
and if that does not recouer him, then it is a signe
that the wonne vnder his tongue annoieth him
(which must be presently pulled out by some Naule
or Needle), & if that satisfie not, he cannot liue,
but will in a short time perish. . . . Dogs are also
many times bewitched by the onely sight of inchanters>
euen as infants, Lambes, and other creatures, accord-
ing to Virgils verse —
Nescio quis teneros oculns mihi fascinat agnos.
For the bewitching spirit entereth by the eie into
the hart of the party bewitched : for remedy whereof
they hang about the neck a chain of corall, as for
holy hearbs I hold them vnprofitable. "
Scepticism is said to be the great fault of scientific
men of the present day. This sin cannot be laid to
the charge of the writers on natural history in former
times, and least of all to the Rev. E. Topsell ; in
proof of which we gave a copy of ' ' the true picture
of the Lamia."
" This word Lamia hath many significations, being
taken some-times for a beast of Lybia, sometimes for
a fish, and sometimes for a Spectre or apparition of
women called Phairies. And from hence some haue
ignorantly affirmed that either there were no such
beastes at all, or else that it was a compounded
monster of a beast and a fish. "
Our author quotes a whole host of Greek and
Latin writers who had heard of some such monster ;
N 2
268
HARD Wl CKE 'S S CIE NCE - G 0 SSI P.
but as their descriptions are very vague, he thinks
they have mixed up a good deal of fable with them.
To leave, therefore, these fables, and come to the
true description of the Lamia, we have in hand : —
"In the foure and thirty chapter of Esay [Isaiah]
we do find this beast called Lilith in the Haebrew,
and translated by the auncients Lamia, which is there
threatned to possesse Babell. Likewise in the fourth
chapter of the Lamentations, where it is said in our
English translation that the Dragons lay forth their
brests. In Hrebrew they are called Eihannm, which
by the confession of the best interpreters cannot sig.
nify Dragons, but sea calues being a general word for
strange wild beasts. How be it, the matter being wel
examined, it shall appeare that it must needes be this
Lamia, because of her great breastes, which are not
competible either to the Dragon or Sea calues, so
then we will take it for graunted by the testimony of
holy Scripture that there is such a beast as this.
Crisostimus Dion also writeth that there are such
beasts in some part of Libia, having a womans face
and very beautifull, also very large and comely shapes
on their breasts, such as cannot be counterfeited by
the art of any painter, hauing a very excellent colour
in their fore parts, without wings, and no other voice
but hissing like dragons. . . . The hinder parts of
this beaste are like unto a Goate, his fore legs like a
Beares, his vpper parte to a woman, the body scaled
all ouer like a Dragon,* as some have affirmed by
the obseruation of their bodies, when Probits the
Emperor brought them forth in publike spectacle."
Gesenius in his Commentary" on Isaiah, says :
" Lilith is, in the popular belief of the Hebrews, a
female spectre in the shape of a finely dressed woman,
which in particular lies in wait for and kills children,
like the Lamise and Striges of the Romans."
In his "Anatomy of Melancholy " Burton remarks
that "The Talmudists say that Adam had a wife
called Lilis before he married Eve, and of her he
begat nothing but demons. "
One of the most remarkable animals figured in this
veracious history is the Mantichora. ' ' A beast, or
rather monster (as Ctesias writeth), is bred among
the Indians, hauing a treble row of teeth below and
aboue, whose grealnesse, roughnesse, and feete are
like a Lyons, his face and eares like vnto a mans,
his eies gray and collour red, hiss taile like the taile
of a Scorpion of the earth, armed with a sting, casting
forth sharp pointed quils, his voice like the voice of
a small trumpet or pipe."
A long chapter is devoted to the Unicorn, in
which he discusses the probabilities of the existence
of such a beast, " whereof diuers people in every age
of the worlde haue made great question."
The Rev. E. Topsell, however, is quite satisfied of
its existence, and he silences his opponents with the
following unanswerable arguments : —
* It is from this description that the artist has evolved the
drawing, of which we gave a copy last month, omitting the
well developed avopuov aiColoy.
" David, in the 92 Psalm, says, ' My horn shall
bee lifted vp like the horn of a Vnicorne,' whereupon
all Divines that ever wrote have not only collected
that there is a Vnicorne, but also affirme the similitude
to be betwixt the kingdome of Dauid and the home
of the Unicorne, that as the home of the Unicorne
is wholesome to all beasts and creatures, so should
the kingdom of Dauid be in the generation of Christ.
And do we think that Dauid would compare the
vertue of his kingdom and the redemption of the
world unto a thing that is not, or is vncertain and
fantastical. The Lord speaketh in this manner to
lob, Will the Vnicorne rest and serue, or tarry beside
thy cratches (Mangers, from this word is derived the
name of the childs game of scratch cradle, properly
cratch cradle or manger-cradle, in allusion to the
manger at Bethlehem), canst thou bind the Vnicorne
with a halter to thy plough to make furrows, or will
he make plaine the clots of the vallies ? Likewise
the prophecy of Esay, the 34 chap., and in many
other places of Scripture, whereby God himselfe
must needs be traduced if there be no Vnicorne in
the world."
Among the varieties of sheep described, he includes
one of somewhat doubtful existence, viz. the Musmon
or Musimon of Latin authors, and which was sup-
posed to be a cross between a ram and a goat.
"Pliny makes mention of a beast called Ophion,*
and he saith hee found the remembrance of in the
Grecian books, but he thinketh that in his time
there was none of them to be found in the worlde ;
heerein he speaketh like a man that did not knowe
God, for it is not to be thought that hee which
created so many kindes of beasts at the beginning,
and consented of every kind two, male and female,
at the generall deluge, would not afterward permit
them to be destroyed till the worldes end, nor then
neither, for seeing it is apparent by holy scriptures
that after the world ended al Creatures and beastes
shall remain vpon earth as the monuments of the
first six daies worke of Almighty God for the further
manifestation of his glory, wisedome, and goodnes,
it is unreasonable to imagine that any of them shall
perish in general in this world." If this theory be
true, naturalists may reasonably hope to find the
Dodo and great Auk still existing.
Many of our readers will, we fear, be inclined to
ask the use of rescuing from oblivion the errors and
fallacies published centuries ago. From a scientific
stand-point the answer must, perhaps, be in the
negative ; but may it not be worth our while occa-
sionally to take a retrospective glance, if only to
ascertain the progress" that has been made ? And it
ought also to teach us to avoid dogmatizing — one of
the greatest faults a scientific mind can be guilty of,
Apart from its scientific merits or demerits, this book
is of considerable interest to the student of English,

particularly with regard to its orthography. Many
peculiarities will be noticed in the extracts we have
given ; for example, the indifferent use of v and u ;
the occasional reduplication of the final consonants in
nouns, to which an e is sometimes added ; the termi-
nation ness, with only one s ; and the omission of

A FEW WORDS ABOUT A LITTLE GNAT.
ON the 1st July a friend gave me two ounces of
Thames water, which had been drawn from the
cistern supplying his house ; and this small quantity
contained more than thirty worm-shaped creatures,
which, upon examination, I found to be the larvae of
some kind of gnat : the largest were about a quarter
of an inch long.
V-
Fig. 224. — Larva of Gnat, natural size j-inch.
The larva of this species has a brown head, with
the eyes, mandibles, and a fine line round the neck,
dark brown; the thorax and the abdomen pale greer.
Two prolegs project from the under side of the
prothorax, and two from the last segment of the
abdomen, which has also, at its extremity, three
270
HARDWICKE'S SCIENCE-GOSSIP.
appendages, and on the top two pencils of hair, each
pencil being supported on a short stalk.
I put my specimens into a small glass vessel.
After some hours I found several tubes of cobweb-
like texture, open at both ends, and slightly tapering,
attached to the sides of it, and in each tube a larva,
which, holding on by the anal prolegs, gave to its
body a vertical serpentine motion, which made a
current of water to flow through the tube. About
once a minute it would contract itself, and then,
pressing its head against the sides of the tube, collect
with its conspicuous mandibles and devour such of
those solid particles which had been drawn in by the
current and were entangled in the tube, as suited its
taste, and occasionally it would turn about and collect
at the narrow end, but it always brought its head
back to its old position at the larger end before it
commenced pumping again.
This larva does not come to the surface of the
water to breathe, neither does the pupa, which also
lives in a tube, and makes the water flow through it
by the undulations of its body, just as the larva did, in
order, I presume, to bring the air contained in the
water into contact with the hairy fringes which border
the segments of its abdomen ; certainly not to obtain
food, for it does not eat. It has no hairs on the
thorax like those represented in the figures of Chiro-
nonius fliimosus.
I was amused to see that each of my pupae kept its
old head under its body, where it rocked to and fro
with each wave of its abdomen ; there it was, with
its dark jaws, its little eyes, and neat brown collar,
and with the same comical, Japanese kind of expres-
sion that it had when it was in its old place. When
the pupae were about three days old they left their
tubes, and after swimming, or rather throwing them-
selves about with the most violent contortions for
three hours or so, and now frequently coming to the
surface, they remained there for a little while, and
then the transformation took place.
Although I watched my captives pretty closely,
many of them changed their state unobserved. Once,
when I went away for two minutes only, I found
on my return the gnat creeping up the side of the
vessel. At last I was fortunate enough to see one
come out. It did not free itself in a careful, delibe-
rate manner, like the common gnat, which, sailing
about in its pupa skin, gently extracts its anterior
legs, and, after carefully placing these on the water,
proceeds to liberate the next pair, and so on ; but it
came forth as though it were being steadily squeezed
out, and then immediately flew away, the whole
operation occupying just fifteen seconds !
I had previously placed a pupa on the stage of my
microscope in order to examine it ; but before I had
time to do so, the skin parted, the head appeared, and
in about eighteen seconds the whole imago was out.
My specimens lived a month as larvae, and from
three to four days as pupa;. I am sorry that I have
been unable to obtain the name of this insect. I
think it is allied, if it does not belong, to the genus
Chironomus. The imago is 1^ line long. The two
anterior legs are distant from the others, and the rost.
rum is short.
The female is yellow, and has short antennae, of
few joints, the terminal one being the largest ; the
male is darker, with the abdomen greenish-brown ;
the tibiae and tarsi dusky ; the antennae plumose, of
many moniliform joints, with the terminal one cylin-
drical, and very long. — Edzvard Cox, Brixton.
A TOUR IN SEARCH OF FOSSILS.
THE experiences of a collector during a run from
Edinburgh to Bristol, and a stay of twelve
days at the latter place, may, perhaps, be interesting
to the readers of Science-Gossip.
The first halting-place was Settle, in Yorkshire,
classic ground to the brachiopodist, mainly through
the labours of Mr. John Burrow. Mr. Burrow was
the son of a doctor of independent means, and spent
his life in working out the palaeontology of his dis-
trict. He was known to all of the inhabitants of the
town to whom I spoke, and an intelligent shoemaker,
who occasionally accompanied him on his rounds,
gave me what information he could, as to his habits
and excursions. He described him as "rather dull-
looking " as a lad, and as one from whose after-life
no great things were to be expected. From what I
had known of his work I was curious to find out as
much as I could about him, wondering, as so much
has recently been said of men in a humble grade of life
who have worked in pretty much the same groove,
what could be said of a man who was above them in
the social scale ; but I had not time to pursue such
inquiries very far ; the sum of what I learnt was that
he was a man who spent nearly the whole of his time
on the moors, that he worked hard, and, uniting
quickness of eye and intelligence with zeal, was able
to accomplish what he did. Mr. Davidson's mono-
graph of the British Carboniferous Brachiopoda bears
frequent testimony to his merits. His collection went
to the Woodwardian Museum, at Cambridge, fetch-
ing a sum which, as he himself said, paid him scarcely
at the rate of a halfpenny per hour for the time
during which he had been making it. He died
comparatively young.
A collector's first experience of Settle would pro-
bably be disappointing. It requires, above all things,
time to know what a locality can produce, and a very
considerable amount of patience and muscular activity
to successfully work a locality that is known. Al-
most in accordance with my expectation, I found
Settle exceedingly barren during the single day I was
able to spend there. A few common Brachiopods
only rewarded my labour, but these, with the beauti-
ful mineralisation characteristic of the limestone of
the district, were thought worthy of preservation. A

few good Productus striaius occasionally occurred on
window-sills and over porches. Many good things
were got when the new line between Settle and
Carlisle was being constructed. The quarries scarcely
repay a visit to the chance collector. The richer
beds are not always worked, and the quarrymen do
not seem to have much to offer. Fish remains, I
was told, occur in the Dent marbles, a few miles
further up the line, but I am not aware of any verte-
brate remains having been found in the carboniferous
limestones of the immediate vicinity.
The next halting-place was Dudley. The fossils,
with which every paleontologist is familiar, are got
at two places, the Wren's Nest and the Castle ;
neither place is far from the town. I spent a day at
the Wren's Nest, but hadn't time to visit the Castle.
The beds I saw were tilted at a sharp angle, and
good weathered fossils are to be found in the debris
at their base. The beds themselves are so crowded
with organic remains that they offer the finest study
possible of an important part of the world's ancient
life. These remains, however, are not easy to
transfer to the collecting-bag, and the geologist must
betake himself to the various places where the softer
shales have become disintegrated, and have yielded
up a part of their fossil contents. His first feeling
will be one of disappointment, even here, where he
is aware of an enormous profusion of organisms, and,
indeed, if his object be merely to secure fine cabinet-
specimens, his disappointment will be keen ; good
trilobites and shells are not easily to be picked up,
but if his object be of a more purely scientific kind,
especially if he has learnt to feel much interest in the
lower forms of animal life, he will not be dissatisfied
with his gatherings. Novelties are, of course, not
easy to find in a locality so long and often wrought
as Dudley ; but it appeared to me very probable,
from the almost inexhaustible abundance of material
to work upon, that something might even yet be
obtained, especially in groups that have not yet
received their full share of attention, as corals, poly-
zoa, sponges, &c. A week's good work would
probably yield some interesting results. Atrypa
reticularis seems to be the commonest fossil, and I
mention it because I found the mineralisation ex-
ceedingly favourable to the preservation of the spires.
Out of a handful thrown into acid, a large percentage
yielded the desired result. If one is at all anxious
to know whence all the good museum specimens have
come, and makes inquiry, he finds that there is
a band of men who make a business of collecting.
They get good fossils still, and an old man, in
particular, had quite recently made several valuable
finds. It is hopeless to attempt to compete with
such men, and the visitor who has thought of getting
them for himself had better give up the idea, and
make for the nearest dealer's shop. There are two
semi-professional dealers at Dudley, a druggist, Mr.
Hollier, and a herbalist, Mr. Fletcher. I only saw
a few of Mr. Hollier's things, but Mr. Fletcher
obligingly showed me what he had. He has some
good trilobites, but seemed unwilling to part with
them. I was told that there was a museum at the
Mechanics' Institute, but it was too late to see it.
The museum which was before it in date has become
defunct, and its collection is scattered.
The neighbourhood of Bristol is perhaps as good a
one for the paleontologist as any in the kingdom.
Several horizons are well represented, and many of
the best localities are easily accessible. I began work
upon the inferior Oolite at Dundry. To give an idea
of the richness of this locality, it may be mentioned
that the quarry is exceedingly small, being used
simply to obtain road-metal from, but that out of it
have come an enormous number of genera and species,
of which specimens occur in almost every museum and
private cabinet in the country. At the Bristol Museum
I counted from this locality 226 species distributed
amongst 67 genera, but a complete list of what it has
yielded would give a much higher figure. This great
abundance of organic remains was a treat to one
coming from the comparatively sterile horizons of
Mid-Lothian.
The chief excavation is near the top and on the
north side of Dundry-hill, close to the main road
leading from Bristol to Dundry, and is two or three
miles distant from the city. A little way down on
the south side is another and smaller quarry, which I
found rich in corals and large Rhynchoncllas, It is of
no use visiting the north quarry unless the workmen
have been getting out some road-material ; this they
get in rather large fragments, and for a small fee will
allow the visitor to set to work upon them, and
gather for himself what he can. In breaking up the
blocks for their own purposes, they put aside the
better specimens themselves, and generally have some
for sale. The sellers of minerals on the Clifton
Downs usually have a few Dundry fossils on their
stalls, in addition to a great many very beautiful
polished carboniferous corals and sponges, which
can be bought at a very cheap rate.
The well-known Rhcetic beds of Aust gave me
occupation for a day. The fish remains occur on the
surface of the Avicida contorta shales, and in bluish-
grey seams which run irregularly through a coarse,
pebbly-looking kind of rock. The beds are exhibited
well up on the face of the cliffs, and the collector is
dependent upon the crumbling away of the marl
beneath for material to work upon. After a high tide
with a strong westerly wind is the best time to visit
the locality. A good deal of material was strewn
about at the time when I was there, and a star-fish
and Ilybodus remains rewarded my search. To
extract good reptilian or fish remains the collector
must prepare himself for hard work, as the matrix is
very intractable, but with patience, and a heavy
hammer and sharp chisel, he will assuredly meet with
good success. Ichthyologists have lamented that
272
HARD WICKE'S SCIENCE- G OSSIP.
so few Ceratodus teeth have been obtained in recent
years. A partial explanation may be found in the fact
of the hard work required to extract them. That the
locality is rich in such remains is well known. The
Higgins Collection recently acquired by the Bristol
Museum is a striking proof of it. Many of the Ceratodus
teeth of this collection are figured in Mr. Miall's
monograph just published. If the visitor at Aust
wishes to spare himself trouble, he may sometimes
find a few things at one of the cottages in the village.
There does not seem to be any well-sustained effort in
any quarter at present at extracting the riches of the
locality.
At first view the limestones at Clifton seem barren,
but a little careful reseaixh soon opens up a better
prospect. Mr. Emery, a gatekeeper at the Suspen-
sion Bridge, obligingly rendered me very material
assistance. His knowledge of the carboniferous lime-
stone of his district is both accurate and extensive,
and he has made vthe aluable discoveiy of seams of
Rhcetic in the limestone of the Durdham Downs. The
upper shales I found exceedingly fossiliferous, and at no
greater distance than the new buildings on the Leigh
side there were beds exposed in which fine Brachio-
pods were abundant. The "Black-rock" quarry,
which has yielded such good fish remains, is unfortu-
nately closed. Wishing to examine the carboniferous
limestone of the Mendip Hills in Somerset, I found
myself, almost by accident, in Burrington Combe, a
glen produced apparently by the same causes as those
which have hollowed out the gorge of the Cheddar
Cliffs, with which it is in line, but on the opposite
slope of the hills. This combe is of considerable
interest both to the physical geologist and palaeonto-
logist. The section exposed is one of very considerable
thickness, and the fossil-bearing beds are accessible.
Brachiopods, lamellibranchs, gasteropods, and corals
were abundant. Good Psammodus teeth would
reward the diligent collector. A fine one fell to my
share. High up on the right-hand side, almost half-
way up the combe, I came upon some shales from
which the earth had fallen, and was delighted at the
display of organic remains. The clip of the beds was
about the same as that of Dudley, which I had just
seen, and the profusion of extinct life nearly as great.
The fossils I observed were chiefly referable to the
genera Chonetes and Spirifei'a, S. atspidata being
quite common. I am not aware that this locality has
been much wrought, but it would unquestionably
repay any good work spent upon it.
Two days upon the inferior Oolite of Bradford,
Wilts, and Minchinhampton, Gloucestershire, con-
cluded the field work of the excursion, and the short
time that remained was spent at the Bristol Museum.
There is evidence of good work in this museum,
especially on the part of the geologists and malaco-
logists. It possesses several very valuable type speci-
mens, and is, on the whole, well arranged for the
display of its collections. It has no funds for pur-
chases, and when the Higgins Collection was in the
market had to resort to the expedient of a public
subscription to secure it, but in spite of this draw-
back it has done exceedingly well, and has received
many valuable donations. The late Mr. Sanders
took great interest in it, Mr. Etheridge, palaeon-
tologist to the English Geological Survey, and many
others, have contributed largely to increase the number
and value of its specimens, and the zeal of the gentle-
man, recently its curator, and now of the Wood-
wardian Museum at Cambridge, has done much to
bring it to its present satisfactory state. It occupies
beautiful premises on a good site. The upper hall is
devoted to Mineralogy, Palaeontology, and recent
shells. The fossils are arranged in table-cases, in
stratigraphical order, and the light is all that could
be wished. A striking feature is the Ichthyosaurus,
completely extracted from the matrix, and suspended
from an iron support. This way of mounting, as
novel as instructive, arose out of a mistake. The
wrong faces of the blocks were, in some instances,
developed, rendering it necessary for the remains to
be entirely extracted, if the specimen was not to be
spoiled.
The lower hall is devoted to Ethnography and
recent Zoology. I was sorry and rather surprised to
hear that more use was not made of this part of the
Natural History collections. The attendance of
students is almost nil. No attempt seems to have
been yet made by those who have the direction of
what biological teaching exists at Bristol, to take
advantage of the facilities which the museum offers.

AN AUTUMN RAMBLE IN EPPING
FOREST.
By Dr. De Crespigny.
Part II.
* I 'HE genus Coprinus has membranous gills, which
become black (with the black spores)* when fully
developed, and finally deliquescent. Coprinus contains
we gathered in a pasturage below the warren. It is a
singular-looking fungus, edible, and remarkable for
its scaly cuticle : the scales are seen in the figure as
tufted and revolute at their ends. In the same pas-
ture grew another and pretty little species called
C. plicatilis, with plicato-sulcate pileus and small
umbone. As it is a good example of this kind of
pileus, a figure in illustration is subjoined. A good
specimen of the genus Cortinarius we gathered in
Inoloma (C.)violaceus, said by Mr. Worthington Smith
to be one of the very best for esculent purposes.
Cortinarius has been subdivided into six sections ;
they have all persistent membranous gills and a
floccose trama ; a veil of arachnoid threads and rust-

found on dung-hills everywhere in A. (Copriiiarius or Pan-

coloured spores. When torn or otherwise dissipated,
the remains of the veil may be usually discerned as
stains upon the bulbous stipe ; but the violet tinge
upon the stipe is not constant, nor is the pileus
violet except when quite young. It is by no means
common.
Most of the smaller specimens of fungi, which
grew upon leaves or on the ground, were damaged.
We made out, however, that the subgenus Myxanim
is well represented.

Hygrophorus is characterized by its waxy hyme-
nium, hymenophorum continuous with the stem and
descending unchanged into the sharp-edged gills.
Specimens of H. psittacinus we obtained from a wet
pasturage : the colour of pileus, gills, and stem is of
a crocus yellow, tinged here and there, on the gills
especially, with grass-green in the young plants, the
stipes hollow and splitting ; the hymenium, too, has
■3. tendency to separate from the trama when dry.
Lactarius is well represented. L. subdulcis is ex-
tremely plentiful. The gills and flesh are milky in
this genus, the trama vesiculose, hymenophorum
confluent with the stem ; two or three of this species
which are of a rufous or cinnamon-brown colour are
much alike ; the milk of L. seriffutis, however, is
watery, and that of L. fuliginosus turns yellowish.
A specimen of Z. blcnnius, pileus greenish-grey,
gills white, was also gathered.

Equally abundant with Lactarius were species ot
Russula. The structural characteristics of this genus
are precisely the same as those of the preceding,
except that the flesh is not milky. Very common
was Russula heterophylla, pileus of all shades of dull
yellow, greenish, purplish, and dull red ; frequent
274
HARD Wl CKE 'S S CIE NCE - G 0 SSI P.
R. fragilis, red when young, but white and polished
afterwards, viscid. Another common species is Rus-
stila nigricans, dark greyish green or dingy olive,
becoming charred as well as the stem, when old ;
umbilicate, as are the Russulas generally, and with
the margins of the elevated borders inflected ; the
gills are white with a black border.
Cantharellits cibarius is sometimes plentiful in
Epping Forest. It may be known by its golden-
yellow colour, infundibuliform pileus, and gills re-
duced to mere folds or swollen veins. We could
obtain no specimen to illustrate this curious structure
of hymenium. The genus has a floccose trama ;
gills in other species thick, swollen, and obtuse.
Marasmins is another genus in which the trama is
floccose; the hymenophorum confluent with the
stem, although of different structure; not confined
to the lamellae, but spread over all the interstices.
M. Oreades is said to be good eating, grows on dry
pastures, generally in rings (the circle is rarely com-
plete) of from six to eight feet broad. The whole
plant is of a dirty cream-colour, pileus more or less
slightly stained with brown, and seldom more than an
inch or two in diameter. We found them on a com-
mon near Woodford.
Intermediate between the gillbearing Hymenomy-
cetes, and those with a porous hymenium, are the two
curious genera, Zeuzilesand D&dalea, both of common
occurrence in forests, and of which the former is
retained in the first-mentioned family, and Dadalea
in the latter ; but the fact is, when fully developed, it
is very difficult, out of a number of specimens, to
decide which is which. Nature is very unaccommo-
dating, and refuses to be tied hard and fast by laws
and rules, as laid down in the books which treat of her
phenomena. The lamellae of Dcedalea are indeed
sometimes so much broken up, in old plants, as to
resemble the toothed processes characteristic of the
hymenium of a Hydmim.

History of the Genus.
IN these papers I do not wish to discuss questions
that are purely geological. I wish to deal only with
one type of a class, out of many of the classes which
fall naturally into the divisional roll of the palaeon-
tologist. But while keeping this before me as a
guide, I cannot ignore the fact that in speaking of
formations it will be necessary to either enlarge or
restrict my meaning when I use certain terms. In
speaking of the Silurian System, this was not so
much needed, but in speaking of the Fenestella of the
Devonian system it will be necessaiy to limit my
meaning, as my remarks on the species will apply
more particularly to the typical Devonian rocks of
Devon and Cornwall.
In 1 84 1, Mr. John Phillips published his elaborate
work on the Geology of Cornwall, Devon, and West
Somersetshire. In this work there are numerous
plates of Fossils, with letterpress descriptions of the
same. Figures and descriptions are given of these
species of Fenestella, for in this work Phillips discards
the word Retepora, and uses Miller's more expressive
term. The specific character of F. laxa is similar to-
that given in his Geology of Yorkshire. ' ' The net-
work is extremely large and irregular, the obverse
bearing two rows of tubular pores, reverse granulously
striated," and the localities are S. Petherwin and
Croyde. Of the F. antiqua Goldfuss, Phillips gives
several very good figures, and his description is little
more precise. He says of one of his figures (35«),
F. antiqua var. that the specimen was sub-conical, and
that the celluliferous face was external. This is clearly
a mistake, for even from the figure it seems to give an
idea that the polyzoon was parasitic on some object.
The corallum was irregular, with thick, slightly
flexuous interstices, very obtusely carinated ; the
dissepiments were thick and short, and placed at
regular intervals ; the fenestrules were oblong, and
the pores were small, with slight prominent margins
about their own diameter apart, and usually
about three to the fenestrule. The species and
varieties are common in the Devonian Limestone of
Plymouth. This description applies to Goldfuss'
figure of Retepora antiqua, and not to Lonsdale's
F. antiqua of the Silurian System. F. anthritica is
another of the Devonian species, but it is not very
well described. The figures are very good, but I
cannot make much out of them. The Hemitrypa
oculata of South Devon seems to me to be clearly
a Fenestella. It is a thin laminar expansion in
a cup-formed mass. The external surface is wholly
covered with numerous round pores or cells radiating
from a centre, and associated in double rows, which
near the centre undergo frequent divisions, so as to
form two such rows. The figures seem to bear, in
some respect, the character of Hemitrypa Hibernica,
and also to the Fenestella {?) Sykesii of De Koninck.
One of Phillips's drawings, fig. 38 E., is decidedly
characteristic of the Fenestella type, and one would
have no hesitation in placing it with that group. I
have been rather more particular with Phillips's
Devonian Fenestella than I should have been had the
work been less scarce. As it is, I have done my best
to furnish the student with his specific characters in
this history of the Genus.
Several American Devonian species of Fenestella
have been figured and described by H. A. Nicholson,
Professor of Biology, in his work on ' ' Ontario," and in
the Geological Magazine for 1874-5. Some of these new
forms are very characteristic, and although they bear

different specific names, there is a tendency of some
to ally with Silurian, while others approach Carboni-
ferous species in character. But every fragment given
by Nicholson is well described — a property that adds
much to the value of his specimens. One of these,
Fenestella magnified, bears a close resemblance in its
non-poriferous aspect to F. laxa of Phillips. To this
particular point Nicholson himself draws the attention
of the reader. I do not, however, set a very high
value upon Phillips' F. laxa from the Carboniferous
or Devonian series. It is very loosely described, and
very loosely figured, both in his Palceozoic Fossils,
and in his Geology of Yorkshire. Nicholson's species,
then, has this advantage over the older description ;
it is well figured and well described. The poriferous
aspect is unknown. He says : " I have only seen a
single specimen of F. magnifiea, and that only exhibits
the reverse side of the ccenecium, but the general
character of the frond so distinctive, that I have no
hesitation in founding a distinct species for its recep-
tion. It is from the Carboniferous Limestone of Port
Colborne, Canada."*
F. marginalis (Nich.) is a very peculiar species.
It is described from a mere fragment, but the charac-
ter is distinct. The polyzoary was fan-shaped, but
of unknown dimensions.! In his critical remarks,
Nicholson says : "The specimen does not enable me
to affirm with certainty that the two marginal rows
of cells were separated by a medium keel, but it
appears highly probable that this was the case. In
the genus, or sub-genus, Fenestrellina (D'Orbigny),
the mesial keel, separating the two rows of large
lateral cells, carries a central row of minute cells. In
F. marginalis, however, the space between the lateral
rows of cells carries a series of minute crowded cells,
which are arranged in two, or sometimes in three,
alternating rows ; so that the central keel, if present,
must have exhibited the openings of two or three
rows of cells. This character, so far as I am
aware, has not hitherto been noticed in any species
of Fenestella, except F. rigidnla (M'Coy), and it
may, perhaps, afford a ground of sub-generic dis-
tinction. "J
Fenestella filiformis (Nicholson) is the most
beautiful and delicate Fenestella that I have ever
seen. It is finer in the branches than the finest and
most delicate of any of my Carboniferous species.
The specimens are only in fragments, and the celluli-
ferous aspect is unknown. Of the branches, Nicholson
says, fifteen or sixteen of these occupy the space of
a quarter of an inch.
Another species from the Hamilton group of the
Devonians of America is figured and described by
Nicholson, which he dedicates to his friend David-
son. It is the Fenestella Davidsoni. From the
peculiar growth of the frond, it approaches nearest in
character to the F. Milkri, of Lonsdale, but both the
branches, fenestrules, and number and character of
cells are altogether different from that species. " In
the general aspect of the celluliferous surface and the
sinuous course of the branches, the species makes a
close approach to some of the species of the genus
Retepora ; but the presence of non-poriferous dissepi-
ments, and the existence of a keel separating two
rows of cells, seem to justify its reference to the genus
Fenestella."* In his "Ontario," Nicholson gives
another species, F. nervata, but having no access to
his work, I am unable to describe it.
There is a striking peculiarity, however, about the
Silurian and the Devonian Fenestella when com-
pared with the Carboniferous species, which marks
them as distinct. But there are no arbitrary lines
about any of the Palaeozoic group, except in the F.
rigidnla and F. marginalis. If the poriferous
character of the keel, or the place the keel should
occupy, has not been exaggerated, this is peculiar ;
but, as I have been myself very much deceived in the
apparently poriferous keel,f I merely record my
doubt, with all due respect to the describers of these
species. Some specimens, too, show this poriferous
keel ozitwardly, but when reduced to sections, the
real cells are contiguous, and all the keel that exists is
the thin, wavy line which separates the two rows of
cells, and even this apparent line is nothing more
than the impingement of the walls of the separate
cells one upon the other.
The Fenestella group seems to have reached its
climax in the Carboniferous seas. No fewer than
twenty-two species have been described by Phillips,
M'Coy, and others, to which Mr. Robert Etheridge,
jun., has added two others from the Scottish series
of Carboniferous shales. Many of these species are
fictitious ; the characters of some of them have been
described from fragments of other species. As, how-
ever, my friend G. W. Shrubsole, F.G.S., is engaged
on a complete revision of the Carboniferous Fenestella,
I will just here indicate the specific character of a
few only of the list. F. membranace, Phillips, is a well-
marked and characteristic species. It is elongate and
conical, bearing— generally — three small pores on each
side of the fenestrule ; it has, moreover, long, solid
non -poriferous roots. F. antiqua, Lonsdale, Retepora
antiqua, Goldfuss, and F. snb-antiqzia, D'Orb.,
are included with this species as synonyms.
F. flabellata, Phillips, vary very much in different
* Geo. Mag., May, 1874, p. 197.
t As the descriptions of these species are easily accessible to
the geological student, I do no more than draw his attention
to a few of the minute details of Nicholson— reference to the
larger description will well repay him for the trouble.

t " I believe that all that has been written about poriferous
keels on the Fenestella is wrong, and that these so-called pores
are only worn-down rows of tubercules. Like you, I have
sectioned specimens showing these worn tubercules, and find
they lead to nothing, and have no connection with the cells. —

localities. It is fan-shape in character; but the
branches of specimens from Richmond, in Yorkshire,
differ materially from those found in North Wales.
It often presents two different characters in well-
developed fronds— so much so that if a good frond was
broken and distributed to several Paleontologists,
asking them to identify the species, two sets of
opinions would be the result. F. frutex, M 'Coy, seems
to be a good species, so also are the F. polyporata,
and the F. wididata, of the same author; but
F. nodulosa, and F. temdfila, are somewhat doubtful.
The F. formosa, of M'Coy, is also doubtful in the
character of the poriferous dissepiment; but the
F. plebeia, F. quadradecemalis, and the F. carinata,
of the same author, have pretty constant characters.
The F. crassa, and F. ejuncida, are doubtful. The
F. hemispherica is a beautiful specimen, but may it
not be the young form of some of the larger specimens
described as species ? Besides these forms there are
several others in my list, but after having examined
many of the fine species gathered by Mr. Shrubsole
from the Halkyn Mountains of North Wales, I am
rather in favour of a reduction than of an extension
of species. My belief is that many of the so-called
species are the result of indiscriminate grouping. The
fault of the confusion, is not so much pressed home
upon the describer as upon the collector. It may be
that no Fenestella bands have been so well preserved as
are those of the Halkyn Mountain group ; and it may
be that collectors have been more careful for general,
than for particular fossils. Be that as it may, the
group well deserves revision, and having a sufficient
knowledge of the material at his disposal, I believe
the work will be well and honestly done by Mr.
Shrubsole.
The Fenestella of the Permian rocks are few in
number— both as regards species and individuals.
The form generally met with in collections is
F. reticularis, of Schlol. In Morris' Catalogue this
is given as F. retiformis, with the synonyms Kerato-
phytcs, Gorgonia infundibuliformis, Goldfuss, and
Rctcporajlustracea, Phillips, but as my own specimens
show only the non-poriferous side, I am unable to
give any minute details respecting the species. The
non-poriferous aspect bears a close resemblance to
some of the Carboniferous, and also of the Silurian
Fenestella ; dependence, however, upon this is unsafe
as a palseontological guide.
In space this genus had a remarkably wide range ;
it being tolerably abundant in the Paleozoic series of
America. In this country the foregoing remarks will
justify my assertion that it was also abundant with
us. De Koninck and others have shown how preva-
lent certain species are in the Bohemian and Belgian
series, some of the species belonging to the latter
extending as far east as India. In time the genus
ranged throughout the whole of the Paleozoic rocks,
becoming extinct, so far as is yet known, at the close
of the Permian era.
MICROSCOPY,
Varnish for Glycerine Mounts.— Some time
since I asked in Science-Gossip for some varnish
which would not be affected by glycerine jelly. No
satisfactory answer being given, I had to fall back on
my own experiments, and am glad to say I have at
last found a varnish, which, worked with others,
answers in the best possible manner. The varnish I
allude to is gold size, and I find the following method
of applying it answer best. Having mounted your
slide, and allowed time for the glycerine to set, go
carefully round the thin glass circle with a warm pen-
knife, then with a fine camel's-hair brush run a ring
of gold size round, by means of the turn-table ; allow
this to dry, then apply another layer, and when this
is dry a third ; lastly, run a ring of white lead varnish
over the gold size, and finish with a ring of green
varnish in the centre of the white if your object be
a vegetable preparation, or red, if it be animal. I
have mounted some dozens of slides in this way, and
in no case have I so far found the varnish to fail.
Let me recommend readers of Science- Gossip, who
like myself have had a difficulty in finding a stable
varnish, to give this method a fair trial. Dr. Car-
penter in his work, "The Microscope," it will be re-
membered, speaks highly of gold size as a varnish.
I consider, however, that without some varnish over
it, gold size does not make a very neat or a very
elegant appearance.— Charles F. W. T. Williams,

New Diatoms. — Melosira Barren (Grev.) var.

Diatoms in Coal.— It is, perhaps, in the recol-
lection of our readers, that about two years ago,.
Count Castracane announced the discovery of marine
and fresh-water diatoms in coal ashes. Professor
W. C. Williamson, at the Dublin meeting of the
British Association, doubted the accuracy of this, and
stated that Professor Roscoe had permitted one of
HARDWICKE'S SCIENCE-GOSSIP.

his ablest assistants to make analyses of various kinds
of coal, in accordance with Count Castracane's direc-
tions, and these ashes he (Professor Williamson)
had carefully examined, but had been unable to
detect any traces of diatomacese. I can confirm this,
having myself made many observations on the ashes
of various kinds of coal and coal shales ; many of the
latter were rich in the remains of equisetums and
ferns, and ought to have contained diatoms, if any
existed at that period. So acute an observer as
Count Castracane could not be mistaken as to the
presence of diatoms in the ashes he examined, and
we must, therefore, come to the conclusion that their
presence was accidental. I have examined very many
samples of chalk, not only from this country, but also
from various other localities, but have never seen any
valves of diatomacece. I should be glad to learn if
any other observer has been more successful. — F.

A Collecting Stick. — The following is a de-
scription of a collecting stick I have made, and found
very useful in collecting diatoms from the bottom of
streams, as it does not disturb the mud and sand, like
the ordinary collecting bottle. A is a bamboo-cane,

the glass-tube, and then by placing it near the object
you wish to get, and letting the ball expand, the
object is drawn up into the tube. On squeezing the
ball it is then forced out into the bottle. The stick
can be also used as an ordinary walking stick. —

ZOOLOGY.
How to Preserve Skins, &c. — I can give your
correspondent J. Y. a really good non-poisonous
receipt. It has stood the test of fifteen years, and can
be well relied on, viz. : — 1. Whiting or chalk, ii lb. ;
2. Soft-soap, lib.; 3. Chloride of lime, 2oz.
Boil Nos. 1 and 2 with about a pint of water, and add
No. 3 while hot. Before adiling the lime see that it
is finely powdered, or else it will not work smoothly.
Another good one is as follows : — Burnt alum, 1 lb. ;
saltpetre, 5 lb. ; pound and thoroughly mix. This is
especially for animals, as when well rubbed in it will
fix the fur and hair admirably, and penetrate the
thickest skin.- — Edward E. Evans.
Mimicry among Vertebrata. — Mr. Wallace,
in his work on "Natural Selection," by way of en-
forcing his arguments, quotes instances of mimicry
among snakes only. In the beginning of 1877, when
I was stationed at Shwaegyeng, in British Burmah, a
wild dog was brought to me, and on the first glance
I thought it was a young deer ! The resemblance
was striking in many ways ; colour, form, and mo-
tions of small deer were imitated in a wonderfully
deceptive manner. The head especially was remark-
able for its resemblance to the head of a doe, the
ears were long and very mobile, and could be thrown
back on to the neck in a way habitual to the female
of the common hog deer. These wild dogs are rare,
but they are to be found on the plains of Burmah, and,
as may be readily inferred, they prey upon the small
deer which abound in the grassy plains of that
country. I kept the animal for several days ; it was
a young one, and was very fierce. I sent it down to
Rangoon as an exhibit for the Phayre Museum and
Menagerie there, but the creature died on the way,
and the person in charge unfortunately threw away
the carcase, instead of preserving it. I hope shortly
to be able to get another of these animals, and shall
do my best to send it alive to England. — Arthur
Hough.
Pronunciation of Scientific Names. —
Mr. Browne (see July No.) is no doubt right in his
suggestion that the Latin qu was originally pro-
nounced like k. In the memoir prefixed to the " De
Natitris Rerum " of Alex. Necham (born 1 157) the
following anecdote is related. "Necham abandoned
his :;chool at Dunstable, and became desirous of
entering one of the monasteries, and he first turned
his eyes to the great Benedictine monastery in his
native town of St. Alban's. He accordingly addressed
an application to the Abbot in these terms, Si vis
veniam sin autem, &c, to which the Abbot, who
appears to have been somewhat of a wag, replied, Si
bonus es venias, si nequam nequaquam " (If you are
good, come ; if bad, by no means come). Nequam
of course being pronounced necham, this pun on his
name offended him, and he did not join the St.
Alban's monastery. — F. Kit ton.
The Alternate Generation of theEchino-
dermata.— Professor Haeckel has recently sent the
following to the San Francisco Microscopical Society :
— " The palingenetic development of the Echinoder-
mata, ordinarily known as metamorphosis, which
leads to important inferences as to their race history,
is to be considered as a genuine alternation of
generations, and especially for this reason, that the
two succeeding generations are destroyed in order to
make possible the change into one another by a
single transformation. The first generation, the
'Nurse,' or so-called larva, is a solitary, bilateral,
limbless individual or 'person,' which consists of only
one piece or antimera, and possesses the greatest
resemblance to true worm larvce. On the contrary,
the second generation, the perfected echinoderm, has
the ground-plan of a symmetrical, five-sided pyramid,
278
HARD WICKE'S S CI EN CE- G O SSI P.
and consists of five antimera or parts ; it forms a true
stock or cormus, which is composed of five articu-
lated, worm-like, bilateral persons. When this
cormus originates within the nurse by budding, a
multiplication of antimera occurs, whereby from one
antimera five arise. This origin can be interpreted
only as a non-sexual reproduction, not as a mere
transformation. The true nature of these genuine
alternate generations is clearly shown by those sea-
stars, in which the body remains free from the five
(or more) independent arms, and the central disk,
which barely unites the latter in the middle, exists
almost as an independent body. These are Ophidi-
aster, ChtTtaster, Brisinga, &c. Particularly inte-
resting in this relation are most species of the genus
OpJiidiaster, or Linckia, from which several specimens
are exhibited (0. diplax, O. ornithopus, O. multi-
formis, and 0. Ehrenbergii). Here the single arm,
which possesses the morphological value of an
articulate worm, is freely detached from the disk, and
every arm forms by regeneration both the central
disk and the four remaining arms. With numerous
specimens of the four species of Ophidiaster selected,
all the various stages of this reproduction process
were shown, and he discussed the significance which
these so-called comet forms of sea-stars possess for
the morphological interpretation of the same. There-
fore we should take as the oldest stem form of the
Echinodermata the Asteroidea, from which as di-
verging branches have developed Ophipridea, Crinoi-
dea, and Echiuoidea. In the last, the centralization
of the whole cormus is carried farthest, and from
them the Holothuroidea have arisen. Thus the Holo-
thuroidea stand most distant from the original form
of the Echinodermata — the Asteroidea."
BOTANY,
Cotoneaster vulgaris.— This plant still exists
in small quantities on the Orme's Head. I saw it
there in July last. — James Brittot.
Polypogon Littoralis.— This rare plant, which
does not appear to have been recorded for Glouces-
tershire, occurred this year in considerable quantity,
on marshy ground, near the north bank of the Avon
river at Bristol. On inquiry it seems that the soil
here has been taken from the river bank and bed
at places much nearer Clifton, when the river was
widened and the new dock-gates constructed, and
brought to this marsh to fill hollows from which the
clay had been dug for manufacturing purposes. Its
appearance is of interest, as furnishing another instance
of the occurrence of new plants when soil that has
been long buried is brought to the surface.
Lizard Orchis [Orchis kircina).—! had sent
to me last June a very fine specimen of the Lizard
Orchis {Orchis hircind). It was found in a chalk-
pit at Greenhithe. As I see from Hooker and
Arnott's "British Flora," published 1850, that the
plant " is very rare (perhaps now extinct)," it maybe
interesting to your readers to know it has been found
so recently. I enclose one dried blossom that you
may be sure of its authenticity. The plant was nearly
3 ft. high, the spike of blossom over 21 in. Per-
haps if it has been found by any other of your
readers they will let you know, as it must be a plea-
sure to know so handsome a plant is not yet extinct.
GEOLOGY,
A New Genus of Fossil Corals. — Mr. James
Thomson, F.G.S., who is well and widely known as
an enthusiastic student of carboniferous corals, has
just published a monogram on a new genus, which he
has named Albertia. He also gives us, in the same
elaborate paper, a short sketch by which it has been
attempted to delineate the internal structure of fossil
carboniferous corals during the last twenty years.
Most palaeontologists are aware that Mr. Thomson
has succeeded in causing thin sections of coral to
photograph themselves on sensitised copper-plates,
so that every line is truthfully portrayed. Mr.
Thomson, after a long account of failures that would
have damped the ardour of a less enthusiastic geolo-
gist, relates his triumph as follows : — "It would be
tedious to enumerate the various other unsuccessful
attempts I made in the way of obtaining casts fitted
for the accurate reproduction of structural details ;
but I may say, generally, that these attempts were
veiy numerous, that they occupied a large portion of
my leisure time for several years, and that they in-
volved a very considerable amount of expense. Out
of these laborious attempts, however, there finally
emerged the process which I now employ, and for
which I claim the merit of being applicable to the
accurate delineation of the minutest details of coral-
line structure, and of being comparatively inexpen-
sive. This process I have now used for two years for
the production of lithographic plates, and quite re-
cently I have succeeded in modifying it so as to pro-
duce electrotypes for use in the ordinary printing-
press. Of the first form of this process, I may say
that it consists in taking an impression of the struc-
ture upon a sensitised copper-plate, that this impres-
sion is then engraved upon the plate, and that a
transfer is thence taken and put upon a lithographic
stone. Of the second form of it, I may say that an
impression is taken upon a plate of sensitised copper,
that the plate is next engraved and etched very
slowly, but somewhat more deeply than in the first
case, that a cast in wax is taken from the plate, and
that from this again is produced an electrotype in the
ordinary way. The fact that the process which I
have now so far described is applicable not merely to
the delineation of structures presented in my own
HARD WICKES SCIENCE- G OSS IF.
279
favourite pursuits, but also to the delineation of the
minute structures which present themselves to the
anatomist, the physiologist, the pathologist, the
botanist, and many others, is, I conceive, one of its
chief merits."

NOTES AND QUERIES.
Animal Ventriloquism. — Two very interesting
notices of Brazilian fauna occur in Mr. Rigg-Wither's
account of his work and wanderings in the forests and
prairies of Parana, the one of a frog, and the other
of a bird. The author does not give a description of
either sufficient for determining their species, but he
refers to both of them as possessing in high develop-
ment the special power of ventriloquism. This is
not only of much interest in itself, but as it is the
first instance I have met with of any animal lower
than man being gifted with this abnormal faculty, I
venture to ask room for the following condensed
abstracts from the "Pioneering in South Brazil," with
a few observations which the narration suggests. At
page 145 of vol. 1, Mr. Rigg- Wither, whilst camping
out near Porta Grossa, notes that ' ' a cry, like the
moaning of a sick child, came wailing on the ear,
apparently from only a few yards off ; the tone, how-
ever, was too musical for a child's cry. The vocalist
was a frog, and soon another from a more distant
spot took up the strain, and the two sang together,
now in solos, now in chorus. " The author " took a torch
and proceded to the spot from whence the sound
was (or seemed to be) proceeding." He " stooped to
search in the grass, when the music seemed to float away
to another place some yards distant, and on following
it, the sound still moved, but nowhere could he dis-
cover whence it came. The fact is, this frog is recog-
nised to be a ventriloquist of no common order " — a
property the author reasonably concludes to be "given
him as a protection against the numerous cranes and
other frog-enemies that would otherwise be guided by
the sound, and soon render the species extinct."
Again, in vol. 2, page 193, a bird, notable for its
shrieking voice, and known as the Bell-bird, is thus
referred to : " It is seldom seen in its wild state,
being, like the musical frog, a ventriloquist of very
high powers, and as a sun-loving bird, a frequenter
of the highest tree-tops, where its snow-white plumage
and transparent wings render it almost invisible, even
when in motion. In size it is but slightly bigger than
a starling, with a voice powerful as a peacock's." From
a description of this bird's performances in a cage, at
Antonia, its notes were heard in every quarter of the
town as well as beyond the outskirts, and seemed at
times " to come from the mountains at the back of
the town fully a quarter of a mile distant from where
the bird was actually encaged." Calling to mind the
peculiar cry of the Corn-crake (Crex pratensis), and
one's similar inability to trace the varying points from
which the sounds appear to proceed, I beg to add a
parallel extract from an account of the habits of this
eccentric vocalist of our own meadows. ' ' The crake,
crake, crake of the landrail may be heard during
May and June, resounding on every side, now close at
hand, as if the bird were not a yard distant, now far
off; while the voices of others in different parts are
unremittingly exerted. The note is the call of the
male to his mate. So shy and cunning is the bird
that it is seldom to be seen, and unless by means of a
dog accustomed to such work, it is almost impracti-
cable to force it to take wing. It seems to elude
pursuit as if by magic, and is here and there threading
its way through the long grass before its pursuer can
imagine it has even left the spot from which its call
had first resounded. Its swiftness and dexterity are
indeed almost incredible." (Knight's Museum of
Animated Nature.) It will be observed that no
attempt is here made to account for the sudden
changes of the cries heard, now near, and now far off.
It is taken for granted that the crake, by some sort
of superhuman speed of foot, can elude its pursuer as.
" if by magic," before it can be imagined to have left
the place from which its call first resounded. The
performances of a human ventriloquist afford the
aptest illustration, if not a credible and rational theory,
for all the conditions of the hypothesis accepted by
Mr. Rigg- Wither being fulfilled by the incidents he
records, and which are remarkably enforced by the man-
oeuvres described in the last extract, of " the sly and
cunning " Corn-crake. I am desirous to learn if any
naturalist has noticed similar phenomena in any other
bird or beast, and if so, whether the solution above
indicated has been referred to, if not recognised.
This marvellous faculty may possibly be a vestige
of a once more extended power conferred on the
animal creation, as a means of defence, by deluding
and so evading their enemies. Can any of your read-
ers assist me in these inquiries ? — A. H.B.
Preserving Animals. — I think Mr. Beaumont
will find the most complete information in Waterton's
"Wanderings in South America," published by B.
Fellowes, Ludgate-slreet, 1852. Further useful par-
ticulars are given in his first series of Essays on Natural
History, Longman, Brown, & Co., Paternoster-row,
price 8/-. An abridged account appears in a small
work on Taxidermy, by J. Gardner, 426, Oxford-
street, price 1/6. Another account is shown in
"Taxidermy," by M. Brown, Bazaar-office. If any
further information is required respecting the details
of the system I shall be glad to quote them from any
of the works named. — J. C. Carritt, King's Lynn.
Preserving Animals. — In answer to W. L.
Beaumont, I beg to furnish an outline of Waterton's
method of preserving animals : — "Wash the animal
well in soap and water with a hard brush. Then
skin the animal, taking out every bone to the last
joint of the toe next the claw, and proceed to pare
down from within the nose, the lips, and the soles of the
feet, and sew up the mouth from the inside, beginning
exactly in the front, and continuing the operation
each way to the end of the gape. Now immerse the
skin in a solution of corrosive sublimate in alcohol ;
take it out and fill it quite full of chaff, and proceed
to support it on the table by introducing into the
abdomen a machine made by joining two pieces of
wood in the shape of a carpenter's gimlet, and of
280

size corresponding to the size of the animal. Let the
shank of this machine hang down outside the skin,
just as though it were a fifth leg in the centre of the
body, and let it pass through a hole in the table, and
then be fastened at sufficient height by a couple of
wedges. Now touch the nose, lips, and orbits of the
skin with a mixture of one part of salad oil and three
parts spirits of turpentine, and repeat this touching
every day till the finish. Then with a penknife cut
small holes on the top of the head, behind the root
of each ear, under the jaws, others on the back, and
one under each foot. Now working through these
holes with a piece of iron, from the size of a large darning
needle to that of a ramrod, and shaped at one end
like a carpenter's pricker, push out every part of the
skin which ought to be pushed out, and reduce with
the end of the finger any part that may be too pro-
minent consistently with the expression and form
which the animal exhibited during life. The lips
must be reformed by means of two irons, one held in
either hand, and working in opposite directions
outside and inside. In due course of time, as the
skin stiffens, the artist will see (as the sculptor does)
the features gradually appear ; and at last the skin
will retain the slightest impression communicated to
it by the touch of the working iron. A slit must be
made in the crown of the head, or under the jaws,
to allow of the artificial eyes to be fixed with a little
putty or wax. Two or three weeks' practice is required
in order to become an adept at this mode of pre-
serving animals ; but of course there must also exist
a considerable native talent and taste for sculpture.
The foregoing account is condensed (perhaps too
much so) from an article on Museums in the first
edition (1838) of Waterton's "Essays on Natural
History." It will be observed that this process is
simply one of modelling : the softened skins of
animals being operated upon instead of the clay of
the modeller or sculptor. Various other methods of
preserving animals (especially birds) have been
described in the "Philosophical Transactions" for
1770, in "The Naturalist's and Traveller's Com-
panion," in the "Natural History of Guiana," in the
Amiens Acad., vol. ii., in the "Boy's Own Maga-
zine" for 1859, in the " Boy's Journal " for March,

Bark Bread. — In a note to page 528 of the Flora
Vectensis is the following : " Panis hie albus est due/is
et gratissimus, prsesertim recens. Usus hujus fa nit
primarius et receptissimus apud," &c. , &c. Linnaeus
says the bread is sweet and grateful, but he does not
say that it is composed solely of the roots of the
Calla ; but he does say, " hasc farina miscetur cum
farina" (he does not tell us in what proportion)
" Cerealium vel Pini, et exinde conficitur panis secun-
dum artem." The above quotation must have been
printed incorrectly, it should be, "Panis hie est albus,
et dulcis, et gratissimus " (this bread is white, sweet,
and very palatable). " Usus hujus panis primaris, et
receptissimus apud," &c. (This is the bread chiefly
used by Norwegians and Swedes, and they like it very
much. ) But the flour from the roots of Calla is first
mixed with rye or barley meal, and often with
powdered pine bark ; and of these the bread is made
in the ordinary manner. We may add, the mixed
bark of the pine is, even now, thus used. — J. F.
Robinson.
Wild Animals and Man. — An interesting lec-
ture was recently delivered at the Society of Arts,
by Sir J. Taylor, on the destruction of life by wild
animals in India. An extract or two may, perhaps,
be of interest. In 1876, 18,273 persons were killed
by wild animals ; out of these, 15,946 lost their lives
by snakes, 917 by tigers, 887 by wolves ; the remain-
der being by leopards, bears, hyamas, &c. In the
same year 54,430 cattle were destroyed. The num-
ber of wild animals killed during that time were
234,830, out of which snakes were 212,371. There
are several ways of compassing the tiger's death.
They are snared in pitfalls and traps, shot by spring
guns, poisoned by strychnine, and killed by sports-
men. The natives of India, especially the Hindoos,
hold the tiger, as they do the cobra, in superstitious
reverence; many would not kill him even if they
could, for they fear that he would haunt or do them
mischief after death. In one instance in the Central
Provinces a single tigress caused the desertion of
thirteen villages, and 250 square miles of country were
thrown out of cultivation. In 1869 one tigress killed
127 people and stopped a public road for many weeks,
until finally killed. The shark is a fierce and bold
creature ; he dashes in amongst the crowds bathing at
the ghats, and though he seldom, if ever, under these
circumstances, succeeds in carrying off his prey, yet
he inflicts a dangerous, often a mortal, wound. These
accidents appear to have become more common of
late years, since the practice of throwing bodies into
the river has been discontinued. — H. Budge.
"Sugaring." — In reply to your correspondent,
" W. W. Walter," I used to do a little in the gentle
art of sugaring, and as I was pretty successful, a few
hints of mine may be of use. The best mixture to
my knowledge is Jamaica foots sugar gently boiled
in stout or porter, care being taken not to bum it.
As most of the sugar known as "moist sugar" is
actually refined sugar, and not the raw material at all,
it is not good for the purpose. When made, a little
rum may be added just before using. Several sugges-
tions have been offered at times as to the advantage
of adding oil of anise seed, and other oils of a similar
nature, as powerful moth attractors, but I do not
think they are so potent as supposed, a great deal
depending on the weather chosen for a sugaring
expedition, which should be a moonless night with a
light south or south-west wind, a moonlight night or
east or north wind being quite enough to ensure an
empty bag. Although the autumn for numerous
reasons is the best time for sugaring, still, there are
other times of the year when lepidoptera are captured
at natural or artificial sugar. In the spring the
catkins of die willow or sallow are most killing traps
for the Tamiocampa?, and a sheet spread under a
willow in bloom will be almost sure to catch such
specimens as Stabilis, Munda, Cruda, Gothica, &c.,
on the branches being shaken. Reverting again to
sugaring, the mixture should be laid on with a brush
on the lee-side of trees, about 5 feet from the ground,
and I have found that exposed trees are the best, I
presume from the fact of the wind carrying the scent
better ; where there are no trees I have succeeded
with pieces of rag or fragments of bark or board,
either fastened on a bush, or in want of that, a post,
gate, or rock. — Edward Lovett, Croydon.
A Strange Place for Marsh Plants. — For
a considerable time operations have been in progress
for the construction of a new wet dock at Leith, and
for this purpose upwards of eighty acres of a low
sand-flat, known as Leith Sands, has been reclaimed
from the sea. The greater part of this being within
tidemark, was consequently covered and left dry
alternately with every tide, and no vegetation, ter-
restrial or marine, was apparent. But since the
reclamation wall was finished, and the salt water

281
excluded, alone; a muddy place on the sands a number
of marsh plants have sprung up, and some of the
species are growing in great abundance, many of
them being at this date (July 1st) in full flower. I
have observed the following : — Ranunculus sceleratus,
Nasturtium officinale, Stellaria uliginosa, Epilobium
hirsutum, Callitrichc verna, Veronica Anagaffis,
V. Beccabunga, Alisma Plant ago, J uncus glaucus,
y. lampocarpus, y. bufonius, Scirpus setaceiis,
Alopccurus gcniculatus, and Calabrosa aquatica. The
first and last-named species are both common on the
coast between Leith and Portobello, but the others
appear to be new. Now the question naturally
occurs, how do they happen to be springing up
there ? I am not aware of any satisfactory explana-
tion that can be given, and supposition will throw no
light on the subject. But as all who take an interest
in the matter will have their own opinions, the fol-
lowing is given as a possible, if not a very feasible,
one. We may suppose that a stream once entered
the frith at this place, that aquatic and marsh plants
grew in and around its margin, that its mouth was
gradually encroached upon and covered by the sea,
and the marsh plants disappeared. But their seeds
remained in the sand in a state of dormant vitality,
and withstood the action of salt-water and other
adverse influences, perhaps for many years, till now,
surrounded by conditions favourable to their develop-
ment, they are again springing up into life and
luxuriance. — D. Douglas, Leith.
A Day at Cliveden. — By the kind permission
of his Grace the Duke of Westminster, I was en-
abled, on Saturday, July 6th last, to take my class at
Westminster Hospital for a field-excursion through
the above grounds. The day was, in every sense,
favourable for such an excursion, and the result was
well worth the journey to Taplow. We were for-
tunate enough in the space of three hours to collect
some 119 different species, representing thirty-nine
natural orders. The walk from Taplow station to
Cliveden is one of the best to be found round London
for its abundance of flowers of all kinds, and the
gravel-pits en route are a storehouse of treasures to
the enthusiastic botanist, who will find himself amply
rewarded for any trouble taken by studies of many
of our most beautiful wild-flowers, from Verbascum
Thapsus, which grows in rare luxuriance, down to the
humble Fedia olitoria. The Hypericacese are well
represented, no fewer than eight species being seen,
and Boraginaceae, Dipsacea:, Solanacece (including
Atropa belladonna) and Onagracere form prominent
features in the neighbourhood. A longer search
would doubtless have only considerably raised the
number of orders represented, seeing that our in-
vestigations, hurried as they were, produced the above
number. — H. IV. S. Worsley-Benison.
Curious Places for Nests. — I dare say your
readers will be able to recall curious instances of the
choice birds have made in selecting a place for a nest,
but perhaps none more eccentric than the follow-
ing. A short time back a tomtit took possession of
a beehive, deserted by its proper inmates, and, having
cleared out the comb, filled the circumference of the
hive with wool and moss, in the centre of which it
built its nest and reared its young. And a friend
now sends me another curious instance. In his garden
were four inverted 12-inch pots. The titmouse
must have had curious stairs down to his nest, which
was budt on the ground in the last pot. — George
Dowker.
Hawks in Ireland. — Can you give me any infor-
mation about the various species of hawks to be
found in this locality, as we have observed four distinct
varieties, and have captured and trained two? The
one we have at present is ruddy-brown on back and
head, with black bars, tail also barred, eye black, full,
and encircled with yellow band of skin, beak with
tooth or notch in upper mandible, emarginated wing,
with notch or sinuosity situated near the end of the
quills, breast fawn-colour, with black markings
perpendicularly ; he has a moustache of black hairs on
the cheeks, head round and full. The first hawk we
had was quite different : he had a flattened head, with
projecting ledge over the eye, which gave him quite
a sinister expression ; back very dark brown, breast
white, with horizontal black bars, very long toes, and
curved claws. Both these birds were taken from the
nest and tamed. As I see natural monstrosities some-
times mentioned in your journal, I mention a deformed
chicken which was hatched here and preserved by me.
It has four legs, three of the legs being at one side,
and of these three legs two have the elbow-joints
reversed (and also the thigh-joint) ; there is but one
thigh-joint for the two superfluous legs, the third leg
at that side has a thigh-joint in the natural position ;
all the legs are perfect as to feet, claws, &c. This
bird chipped the shell, but died in coming out. It is
a Bramah.
Izaak Walton. — Perhaps some of the readers
of Science-Gossip may be interested to hear that a
marble bust has just been placed in St. Mary's
Church, Stafford, of Izaak Walton. The ceremony of
unveiling was performed by the Earl of Lichfield.
The bust has inscribed upon it, "Izaak Walton,
Piscator; born in the parish of Stafford, August 9th,
1593 ; baptized in St. Mary's Church, September
2 1st, 1593 ; buried in Winchester Cathedral, Decem-
ber 19th, 1683. Erected by public subscription,
1878." The bust was decorated by a Stafford lady
with various water and other plants, such as the
gentle old fisherman loved so well, and which still
grow luxuriantly among the bright streams, so plenti-
ful about his native town, where the author of the
"Complete Angler" first imbibed his love for angling,
and still greater love of nature. The poor of Stafford
receive still an annual benefit from the friend whose
bust they can now look at, and which will, in a
measure, enable them to realize their kind benefactor.
The "Complete Angler" has had its adverse critics,
but Charles Lamb, in a letter to Coleridge, the poet,
dated October, 1796, speaks of it in these words : "It
would sweeten a man's temper at any time to read it ;
it would Christianize every discordant angry passion :
pray make yourself master of it." The " Complete
Angler " has gone through well-nigh sixty editions in
this country alone. — E. Edwards.
Spider Instincts. — Seeing a paragraph in your
September number illustrating the possession of an
acute instinct in spiders encourages me to trouble you
with one or two observations of a like nature that have
come across myattention in watching spiders' motions.
I was watching recently the completion of a web, and
observing the apparent self-satisfaction with which
the spider at the finish settled down, after some
tightening and fortifying processes, in the centre.
It seemed to me that the spider in question settled
down as if in the full happiness of a domestic
establishment — say, house, pictures, and so on, and
the only remaining need would be the daily bread
that he would require. Reflecting thus, I wondered
how far he would resent any infringement or slight
disturbance upon his "castle;" to ascertain which,
I put a small curled-up leaf through, or partly so, one
of the interstices at the lower part of the web. I w.is
282
HARD WICKE 'S SCIENCE - G OSS I P.
astonished at the promptitude of Mr. Spider's observa-
tion : he was at once militant, and sallied forth, and
gradually one by one appeared to unhook the web
wherever it had hold of the upper part of the leaf, so
that being thus loosed the leaf rolled over until again
suspended at a lower level (i.e. just the breadth of the
curl of the leaf) by the film which had fastened to the
lower part originally, and which, of course, now
became the top part. Quicker than the time taken
to read this, the spider seemed in like manner to
unfasten the newly-placed upper part, and of course
the leaf rolled over again, and this method of
proceeding was continued until at last the leaf was
rolled beyond the limits of the web. Thus freed from
such an intrusion, the spider seemed to squat down
again comfortably enough in the centre. Surely,
thought I, another attempt will not be cruel, and so I
placed an angular bit of a leaf (about half an inch
square) in the upper part of the web. Immediately my
friend started forthagain. Takingstock of theinvading
leaf, he seemed to decide that a new method of attack
was necessary in this case, and so he speedily
unbuckled each entangled corner of the leaf, and
grasping the latter with the full expanse of all his
limbs, he seemed to take it out of the mesh, and by
a herculean feat to expel and throw it away outwardly
from all contiguity with the web, so that it at once
fell to the ground. After this, he returned to the
domestic hearth in the centre. I was singularly
struck by the apparent method pursued in face of
these difficulties, and did not again impose upon his
good nature for any further edification. On another
occasion, a very large spider had spun a web across
the frontage of some Virginian creeper leaves. I had
no experimental intention in disturbing the "animal,"
and so, I forget whether I destroyed the web or
merely commenced by teasing the spider. Which-
ever it was I however remember that he presently
beat a quick retreat beneath some of the curved
leaves, and from one place of refuge to another I
continued to fidget him. At last — perhaps he was
exhausted — he seemed to say, " I shall go no further,"
and the little twig (about a foot long) in my hand
with which I had teased him, failed to dislodge him
from his chosen refuge. He kicked out in reprisal
to my annoying him, and seemed to wince, so I
imagined, with great indignation. While this was
going on, I happened to pull my twig of branch
nearer to myself, and observed that the spider had
attached a line to the end of it, and that it was con-
tinuous and unbroken. It immediately struck me to
test the length to which, in the spider's wrath, I
might extend the film. Steadily and carefully I
carried my twig across a distance of about 9 or 10
paces of ground (about 22 feet) and fixed the free end
of the twig branch into the trunk of an adjacent tree.
I had therefore stretched a fine filamentous thread
across a distance I never expected, and although it
was so exceedingly fine and attenuated that it was only
by difficulty that I could trace its course, yet it was
apparently as continuous and intact as a telegraph
wire. To prove this, I picked up some blades of
grass, and by bending them into an angle I was
enabled to hang them ztpon the spider line. At
varying distances I placed a blade here and then a
blade there — only, by-the-by, in single blades, for I
was afraid of overtaxing the " line." If I remember
aright, I had hung up five of these blades ; but
the weight of the sixth proved to lie the straw
which broke the camel's back — my line broke. This
seemed an extraordinary case, for the spider seemed to
throw out an unlimited length of " wire,'' and seeing I
was enabled to put thereon five or six blades of grass —
each blade being probably of greater weight than
the whole length of film — he might perhaps have
allowed me to "runout" 30 feet or more of his
gossamer thread had I carried my twig that length
in the first place. My last observation of spider
instinct has been in the construction of the web itself,
but I fear to trespass further on your space just now,
however interesting and wonderful these phenomena
of nature and life may be. — J. F. S.
Engineering Skill of a Spider.— The follow-
ing specimen of the engineering skill possessed by a
spider may possibly interest your readers. It was
discovered in an office in this town (Omagh), and was
kindly shown to me by a gentleman connected with
the concern. A spider, desirous of making a web,
being either hard-up or taking a thoughtful view of
matters, appropriated a string for an outside border,
and that in a very curious manner. The string was
a stout one, and hung perpendicularly from a beam.
Moreover, it had a copper-wire hook attached to its
end. The spider must have crept clown the string,
and fixed the end of one of its own lines to the eye
of the copper hook, then ascended the string, carrying
its own line with it, walked along the beam as far as
nine inches, and then fixed the other end of its line.
It must then have pulled bit by bit at the line, till it
had drawn up the copper hook, and made the string
describe a curve; and considering the size of the
string and the size of the spider, it must have been a
rather arduous task, requiring plenty of patience and
perseverance. It then, by a few more lines cleverly
placed, managed to relieve the strain on the main
line, and complete the foundation. The web was
never completed, but was left in its present unfinished
condition. — Isaac Crawford.
Cat and Rabbit. — When living in Essex a few
years back I made the acquaintance of a splendid
cat, of a glossy black from the tips of his whiskers to
the end of his tail. In temper and disposition he
differed from most pussies, for he was a morose old
fellow, and seemed to have very little affection for
anything but cat's-meat. The cry of "meat " seemed
to electrify him, but after his " haporth " had been
duly disposed of he would retire within himself, and
take no further heed of temporal things. A more
unsociable old Turk could not well be imagined.
And yet — would you believe it?— this reserved old
character had a soul (or its equivalent) tucked away
somewhere under that black exterior, and this is what
brought it out. Another member was added to the
family in the shape of a glossy black and white rabbit,
which in a short time was leading a very ' ' free and
easy" life on the premises. Well, between this
pretty creature and the morose old "blacky" an
acquaintance sprang up which by degrees ripened
into a downright fancy for each other's society. Then
they took to romping and playing together, and
after a time the two oddly-matched animals might
be seen lying on the hearthrug together, pussy's sable
paws lovingly clasped round bunny's snowy neck. —

A Mysterious Gift. — I beg to draw P. A.
Allan's attention to the following paragraph, relating
to the wonderful power of sight possessed by M.
Fillifay. It is taken from awork entitled "Mauritius
or the Isle of France," by the Rev. F. P. Flemyng,
M.A., F.R.G.S. "It was from this station (viz. the
long Mountain) that the notable M. Fillifay, some
years ago, used to astonish the colonists, and indeed
the world, by the singular power of sight which he
possessed. His time for observation was usually at
dawn, and by directing his vision to the clear unclou-
ded sky (and not to the horizon), he could behold,
HARDWICKE'S SCIENCE-GOSSIP.
283
inverted (with the naked eye), any object within the
singular circuit of his sight. The accuracy of his
observations was verified when the British squadron
was assembling at Rodrigues (an island 300 miles
eastward of Mauritius), in the year 18 10, for the
attack upon the island. M. Fillifay stated so to the
French governor, and was, it is said, imprisoned for
raising false alarms. At another time he discerned
what he described as two ships joined together, or, if
there were such a thing, a four-masted vessel ; within
a few days a four-masted American schooner arrived
in Port Louis harbour. He also described a large
Indiaman dismasted when nearly 400 miles from the
island, and afterwards announced that he could see that
she was erecting jury-masts, and was steering for that
port. This proved to be the case. He was a pen-
sionnaire on the Treasury, and for years used to render
* his report ' at the Port-captain's office, which was
always written down by the officer as he laconically
announced it: A ship, N.E. 200 miles, nearly
becalmed ; a schooner, W., will make the land to-
morrow ; two brigs standing to the southward, &c.
It is a remarkable fact that, although this old man
visited Bourbon, Europe, and several other places, he
was unable to exercise this singular faculty of vision
anywhere but at Mauritius. This, most probably,
arose from the singular rarity of the atmosphere on
this island, which is certainly most remarkable. He
is since dead. He professed, at one period of his
life, to be able to teach this mode of vision, and even
obtained a fair and ambitious pupil, but he found
that a Power beyond his could alone impart this
wonderful gift." — J. Henry Maughan.
Have Palms Tap-roots ? — As a rule the radicle
of monocotyledonous seeds is little, if at all, developed ;
so that tap-roots are generally said not to occur in the ,
class. A true tap-root must be the direct prolongation
of the radicle. Palms seem, however, to be some-
what exceptional, to judge from the most readily
accessible account of their germination, viz., that in
Mr. W. B. Hemsley's papers on Garden Botany in
the Garden, vol. xiii. (187S), p. 288 (March 30),
from which I take the substance of what follows.
The radicle or primary root is very often vigorous in
seedlings, but it is stated that it is soon replaced by
succeeding roots which appear above its apex, i.e. are
lateral adventitious roots like those of bulbs. Whether
this is invariably the case is uncertain ; but the genus
Borassus is a good example of this replacement.
The stout tap-root of the young seedling in this genus
is soon surrounded by adventitious roots, to which it
surrenders its work, itself dying off. In another
genus, Sabal, however, the primary root seems to
be a lateral outgrowth of the embryo, the radicle
apparently not being at all developed. On the whole,
the preacher who said that palnW>ft?j had not tap-
roots was decidedly nearer the truth of the two. —

Hackney Microscopical and Natural His-
tory Society (194, Mare-street). — The members of
this society made another excursion on Saturday
afternoon, the 19th October, under the presidency of
one of the honorary members, Worthington Smith,
Esq., F.L.S., F.R.M.S. The place of assignation
was Chingford, from thence through the old forest to
High Beech, returning by way of Lough ton. The
special objects of research were "fungi," which are
found in this part of the forest in quantity and variety
sufficient to repay the labours of the numerous com-
pany assembled, though comprising entomologists,
microscopists, and students devoted to other branches
of natural history. The weather was fine, perhaps
rather too dry for the specific object in view ; the
forest was clothed in the varied tints of its autumnal
foliage. The way being led by such an authority on
" fungi " as the president for the occasion, gave to
the excursion an interest and charm peculiarly enjoy-
able ; and the instruction thus gained by an afternoon
spent in the investigation of this page of nature's
history will long be remembered by those who were
so fortunate as to be present. No fewer than thirty-
six species of fungi were collected and identified.
What was the "Fagus" of the Latins? —
Was the Rev. J. Mitford (formerly editor of the
Gentleman 's Magazine) right when he asserted that
"fagus" must mean the sweet chestnut? because
Caesar says the Britons had not the fagus. Landing
in Kent or Sussex, Cassar must have seen the beeches,
which love a chalky subsoil. The "Spanish c/iestmd,"
as it is often called, is no doubt an importation from
abroad. — W. H. Freeman, Reepham, Norwich.
Lapwing and Hawk. — Some five years ago
Mr. G. R. Bull, of Stafford (who related to me the
incident), was driving out one morning, a few miles
from Stafford, with, I believe, Dr. Day, when they
suddenly heard a confused rustling noise overhead,
and something then plumped down into the ditch by
the roadside. On alighting they found a hawk and
lapwing in deadly embrace, the hawk's talons em-
bedded in the lapwing's breast, the bird just expiring ;
the hawk already dead, from the beak of the lapwing
being fixed in the eye and brain of his enemy. As
the latter had made his fatal pounce, the intended
victim had made one supreme effort, and by a lucky
peck in the one vulnerable spot, avenged his own
death.— Alf. Freer.
Ornithological Instruments. — Where can
scissors for cutting the bones of the embryo in birds'
eggs, described in Prof. Newton's " Suggestions for
forming Collections of Birds' Eggs," be procured? also
German-silver blowpipes ? — Beta.
Arge Galatea. — Could any of your correspon-
dents inform me as to whether Arge Galatea has ever
been noticed near Bedford before ? I took a rather fine
specimen at the close of August this year. — W. E.
Fairbridge, Bedford.
" Bob-OWLERS." — It may interest those of your
readers who care to note the local names of plants,
insects, &c, to know that in Staffordshire the thick-
bodied moths are called " Bob-owlers." — K. D.,
Almondsbury.
NOTICES TO CORRESPONDENTS,
To Correspondents and Exchangers. — As we now-
publish Science-Gossip a week earlier than heretofore, we
cannot possibly insert in the following number any communi-
cations which reach us later than the 9th of the previous
month.
W. T. Horn.— Thanks for the specimen of Helichrysiott,.
which, unfortunately, was jumbled into an indistinguishable
mass when it reached us. Get Burbidge's " Cool Orchids and
How to Grow Them," with plates, published by Hardwicke &
Bogue, 192, Piccadilly, price 6s. It is the best work of the
kind we know.
A Young Beginner.— Mr. Collins has recently issued what
he calls a " Histological Microscope," at ^5. 10s., which
would answer all your requirements. It is a marvel of me-
chanical skill, and can be easily stowed away. It is sufficient
for all the requirements of a natural history student.
W. H. Jones.- The spikes of Plantago are the largest we
have seen.

HARDWICKE' S SCIENCE-GOSSIP.
E. E. Evans. — For details concerning the construction of an
Egg Cabinet see " Notes on Collecting and Preserving Natural
History Objects," price 3s. 6d., published by Hardwicke &
Bogue.
K. D. (Almondsbury). — Orbitoliiia. is a genus of fora-
7/iiui/crir.
G. O. Howell. — The calyx segment of the Bud of Fuchsia
you enclosed has reverted to the condition of a true leaf.
H. F. Rasell.— Get "Half-Hours with the Microscope,"
bv Dr. Lankester, with chapter on the " Polarisation of Light,"
by F. Kitton, published at 4s. by Hardwicke & Bogue, 192,
Piccadilly, London.
A. Smith. — Get Cooke's " Microscopic Fungi," (illustrated)
price 6s. London : Hardwicke & Bogue, 192, Piccadilly.
K. D. — Bentham's " Handbook of the British Flora," pub-
lished by L Reeve & Co. ; and the Second Edition of
" Hooker's Student's Flora of Great Britain," just out, pub-
lished by Macmillan.
R. Rattray. — Many thanks for your excellently mounted
slide of Licmophora flabellata.
M. Shaw. — Accept our thanks for seedlings of the Date
Palm.
W. H. Shrubsole. — "Banded-flints" were originally
formed by the filling-up of cavities in nodules, layer by layer.
Subsequently the nodules have been broken up, and the harder
banded parts liberated, and rolled into the shapes and appear-
ance in which you see them. (2). The boring appears to have
been made by some other mollusc than Teredo. (3). No doubt
the concretionary nodules, and the appearances you describe,
are due to the soft, decomposing, organic matter of the animals
whose hard parts usually form the nuclei, having caused
chemical segregation.
To Querists. — We are obliged to postpone the publication
of several answers until our next, on account of want of space.
