THINGS TALKED OF IN LONDON.

_May, 1852._

As May of last year was made memorable by the opening of the Great

Exhibition, so will the present month become famous for the pulling

down of the Crystal Palace. Parliament has decreed it, and there is an

end of the matter. If the people by and by find reason to complain of

the proceeding, they will have no one to blame but themselves;

because, had they spoken out as only a whole nation can speak, the

decision of the legislature would have been on the other side of the

question. We are promised, however, that it shall be re-erected on

some other site, and herein must solace ourselves for disappointment

at the removal, while waiting for the National Exhibition to be opened

at Cork, or that of the Arts and Manufactures of the Indian Empire

promised by the Society of Arts. Besides this, the present May will be

noteworthy in the annals of ocean steam-navigation: the steamers to

Australia are to commence their trips, as also those to Brazil and

Valparaiso. Who would have dreamed, twenty years ago, that the

redoubtable Cape Horn would, before a quarter century had expired, be

rounded by a steamer from an English port? Captain Denham is about to

sail in the _Herald_, to survey the islands of the great ocean, one

object being to find the best route and coaling-stations among the

islands for steamers from the Isthmus to Sydney. The vessel will carry

an interpreter, a supply of English seeds and plants, and a number of

articles, to serve as presents for the natives. Should this survey be

successful, and the United States' expedition to Japan produce the

effect anticipated, the vast solitudes of the Pacific will be erelong

continually echoing with the beat of paddle-wheels and the roar of

steam. Rapid intercommunication will bring about changes, whereat

politicians and ethnologists shall wonder. The Chinese still keep

pouring into California by shiploads of 200 or 300 at a time, where

they will perhaps learn that a year of Anglo-Saxondom is 'worth cycle

of Cathay.' We may regard as evidence of progress, that Loo-choo has

been visited by Captain Shadwell of the _Sphynx_; he was received with

great favour, and conducted to the royal city of Shooi, three miles

inland. Readers of Captain Basil Hall's pleasant account of the same

island will remember, that he was jealously forbidden to approach the

interior. Do the Loo-chooans want to conciliate an ally? If, as is

said, Japan is to become to the Americans what India is to us, we

shall have them for neighbours in the east, as we now have them in the

west. It will be an interesting event should England, America, and

Russia some day meet on the Asiatic continent.

One good effect of railways, as you know, has been to cheapen coal,

and excite activity in heretofore dormant mining districts--results

which tell upon the trade in sea-borne coals. To meet this emergency,

a scheme is on foot for sending coal from the Tyne to the Thames in

steam-colliers, which, by their short and regular passages, shall

compete successfully with the railways. The experiment is well worth

trying, and ought to pay, if properly managed: meantime, our railways

will extend their ramifications. Looking for a moment at what is doing

in other parts of the world, it appears that there are at present 2000

miles of railway in France, besides as much more which is to be

completed in four years. Portugal is only just beginning to think of

iron routes: a few wakeful people are trying to impress that backward

land with a sense of the advantages of rapid locomotion; and it is

shewn that, by a simple system of railways, Lisbon would be placed at

sixteen hours' distance from Madrid, forty-three from Paris,

fifty-three from Brussels, and fifty-seven from London. Would it not

be a comfort to be able to run away from the north-east monsoon, which

has so long afflicted us, to the orange groves on the banks of the

Tagus, in about two days and a half? A telegraph is about to

be carried from the Austrian States over the Splugen into

Switzerland--the Alps, it would appear, being no bar to the

thought-flasher. There is a project, too, for a regular and universal

dispatch of telegraph messages from all parts of the world. A mail and

telegraph route from the Mississippi across to San Francisco is talked

about. The proposer considers that post-houses might be erected at

every twenty miles across the American continent, in which companies

of twenty men of the United States' army might be stationed, to

protect and facilitate the intercommunication; news would then find

its way across in six or seven days. Should this scheme fail to be

realised, the Americans may content themselves with having nearly

11,000 miles of railway already open, and another 11,000 in progress.

A beginning is made towards the abolition of the duty on foreign books

imported. Government have consented that certain learned societies,

and a number of scientific individuals, shall receive, duty free, such

scientific publications as may be sent to them from abroad.

Considering that the whole amount realised by the present customs'

charge is only L.8000, it is easy to believe that the authorities will

shortly have to abolish it altogether. Another question in which books

are concerned, is the dispute that has been going on for some time

among the fraternity of booksellers, as to whether a retailer shall be

allowed to sell books for any price he pleases, or not. Whether

'free-trade' or 'monopoly' is to prevail, will depend on the decision

of the arbitrators who have been chosen. Leaving out all the rest of

the kingdom, there are nearly 1000 booksellers in London; so the

subject is an important one. This number affords a notable datum for

comparison with other countries. In Germany, the number of booksellers

is 2651, of which 2200 are retailers, 400 publishers only, while 451

combine the two. They are distributed--36 in Frankfort, 56 in

Stuttgart, 52 in Vienna, 129 in Berlin, 145 in Leipsic. The figures

are suggestive. Another fact may be instanced: in 1851 the number of

visits to the British Museum for reading was 78,419--giving an average

of 269 per day, the room having been open during 292 days. The number

of books consulted was 424,851, or 1455 daily. This is an agreeable

view of what one part of society is doing; but there is a reverse to

the picture, as shewn in a recently published parliamentary report,

from which it appears that in 1849 the juvenile offenders in England

numbered 6849--in Wales, 73--of whom 167 were transported; in 1850,

the numbers were respectively 6988, 82, 184, shewing an increase under

each head. Of the whole number in confinement last November, 169 were

under thirteen years of age, and 568 under sixteen: 205 had been in

prison once before, 90 twice, 49 three times, 85 four times and

upwards; 329 had lost one parent, 103 both parents; 327 could not

read, and 554 had not been brought up to any settled employment. These

facts may be taken as demonstrative of the necessity for multiplying

reformatory agricultural schools, such as have been established in

various parts of the continent with the happiest effects.

Among the prizes just announced by the French Académie, is one for

'the best work on the state of pauperism in France, and the means of

remedying it,' to be adjudged in 1853. It is greatly to be wished that

some gifted mind would arise capable of taking a proper survey of so

grave a question, and bringing it to a practical and satisfactory

solution. Some people are beginning to ask, whether it would not be

better, with the proceeds of poor-rates, to send paupers to colonies

which are scant of labourers, rather than to expend the money in

keeping them at home. The Académie of Literature, too, has offered a

prize for an essay on the parliamentary eloquence of England--a

significant fact in a country where the legislature is not permitted

to be eloquent, and where forty-nine provincial papers have died since

the 2d of December. Coming again to science: the judicial _savants_

have awarded a medal to Mr Hind for his discovery of some two or three

of the minor planets--an acknowledgment of merit which will not fail

of good results in more ways than one.

Various scientific matters, which are deserving of a passing notice,

have come before the same learned body. Matteucci, who has been

steadily pursuing his electro-chemical labours, now states that with

certain liquids and a single metal he can form a pile, the

electro-magnetic and electro-chemical effects of which are much

greater than those obtained with the old piles of Volta and Wollaston,

and come nearer to those of the batteries of Bunsen and Grove. As yet,

he withholds the particulars, but they will shortly be forthcoming. M.

Dureau de la Malle, in remarks on the breeding of fish, a subject

which has of late occupied much attention in France, says, that he has

now discovered the reason 'why domestic servants in Holland and

Scotland, when taking a situation, stipulate that they shall not be

made to eat salmon more than three times a week;' it is, the insipid

taste of young salmon. It is safe to say, that however much M. de la

Malle may know about fish, he knows but little of the habits of the

countries to which he refers. M. Yvart mentions a fact that may be

useful to graziers--the breed of cattle has been improved in France by

the introduction of the Durham bull; but, as experience has shewn, it

is at the expense of certain qualities deemed essential on the other

side of the Channel. Here, we require meat as speedily as possible in

young animals for consumption in our great towns; there, the great

rural population use milk largely, and keep the animals longer before

they are killed. The quantity of milk, it appears, is materially

reduced in the Durham breed, and on this account M. Yvart suggests,

that it should not be too much encouraged. Then there is something

about dogs by Messrs Gruby and Delafond, who shew that the worms which

have long been known to exist in the larger blood-vessels of certain

dogs, are the parents of the almost innumerable _filaria_ or

microscopic worms, found circulating also in the veins. The number

generally in one dog is estimated at 52,000, though at times it is

more than 200,000; and being smaller than the blood-globules, the

creatures penetrate the minutest blood-vessels. They are met with on

the average in one dog in twenty-five, though most frequent in the

adult and old, and without distinction of sex or race. The examination

of the phenomenon is to be continued, with a view to ascertain whether

dogs infested with these blood-worms are subject to any peculiar

disease.

More interesting is the account of a successful case of transfusion of

blood in the human subject, performed in presence of the ablest

surgeons of Paris. A woman was taken to the Hôtel Dieu reduced by

hemorrhage to the last stage of weakness, unable to speak, to open her

eyes, or to draw back her tongue when put out. The basilic vein was

opened, and the point of a syringe, warmed to the proper temperature,

was introduced, charged with blood drawn from the same vein in the arm

of one of the assistants. The quantity, 180 grammes, was injected in

2-1/2 minutes, after which the wound was dressed, and the patient

placed in a comfortable position. Gradually, the beatings of the pulse

rose from 130 to 138, and became firmer; the action of the heart

increased in energy; the eyes opened with a look of intelligence; and

the tongue could be advanced and withdrawn with facility, and regained

its redness. On the following day, there was a little delirium, after

which the pulse fell to 90, the signs of vitality acquired strength,

and at the end of a week the woman left the hospital restored to

health. Cases of successful transfusion are so rare, that it is not

surprising the one here recorded should have excited attention among

our physiologists.

People inclined to corpulence may profit by M. Dancel's observations

on the development of fat. He says, that some of his patients, whose

obesity was a constant inconvenience and cause of disease, 'lost very

notably of their _embonpoint_ by a change in their alimentary

regimen--abstaining almost entirely from vegetables, feculent

substances, diminishing their quantity of drink, and increasing, when

necessary, their portion of meat.' On another, subject, M. Guérin

Méneville believes he has found a new cochineal insect (_Coccus fabæ_)

on the common bean, which grows wild in the south of France, and in

such abundance, that a considerable quantity may be collected in a

short time. The yield of colouring matter is of such amount, that a

project is talked of for cultivating the plant extensively.

A communication has been made to the Geological Society at Paris by M.

de Hauslab, on a subject which has from time to time occupied the

thoughts of those who study the _physique_ of the planet on which we

live--namely, the origin of the present state of our globe, and its

crystal-like cleavage. After a few preliminary remarks about

mountains, rocks, dikes and their line of direction, he shews that the

globe presents the form approximately of a great octahedron

(eight-sided figure); and further, that the three axial planes which

such a form necessitates, may be described by existing circles round

the earth: the first being Himalaya and Chimborazo; starting from Cape

Finisterre, passing to India, Borneo, the eastern range of Australia,

New Zealand, across to South America, Caracas, the Azores, and so

round to Finisterre. The second runs in the opposite direction;

includes the Andes, Rocky Mountains, crosses Behring's Strait to

Siberia, thence to the Altaï, Hindostan, Madagascar, Cape Colony, and

ending again at the Andes of Brazil. The third, which cuts the two

former at right angles, proceeds from the Alps, traverses the

Mediterranean by Corsica and Sardinia to the mountains of Fezzan,

through Central Africa to the Cape, on to Kerguelen's Land, Blue

Mountains of Australia, Spitzbergen, Scandinavia, and completing

itself in the Alps, from whence it started. These circles shew the

limits of the faces of the huge crystal, and may be divided into

others, comprising forty-eight in the whole. The views thus set forth

exhibit much ingenuity; and when we consider that metals crystallise

in various forms, and native iron in the octahedral, there is much to

be said in their favour.

We shall probably not be long before hearing of another gold field,

for Dr Barth writes from the interior of Africa, that grains of the

precious metal have been found in two rivers which flow into Lake

Tchad, and that the mountains in the neighbourhood abound with it.

Should the first discovery be verified by further explorations, gold

will be more abundant than it now promises to be, and Africa perhaps

the richest source of supply. Apropos of this continent, a French

traveller is about to prove from the results of a journey from the

Cape towards the equator, that the Carthaginian discoveries had been

pushed much further towards the south than is commonly supposed.

Agassiz, who, as you know, has become a citizen of the United States,

has had the Cuvierian prize awarded to him for his great work on

fossil fishes--an honour approved by every lover of science. This

distinguished writer says, in his latest publications on fossil

zoology, that the number of fossil fishes distributed over the globe

is more than 25,000 species; of mammifera, over 3000; reptiles, over

4000; shells, more than 40,000; numbers which greatly exceed all

former calculation. Of other American items, there is one worthy the

notice of apiarians: some emigrants who sailed from Boston wished to

convey a hive of bees to the Sandwich Islands, where the industrious

insects have not as yet been introduced; all went well until the

vessel reached the tropics, and there the heat was so great as to melt

the wax of the combs, and consequently to destroy the bees.

Lieutenant Hunt, of the American Coast Survey, states that

copper-plate engravings may be copied on stone; specimens are to

appear in the forthcoming report. To quote his description: 'A

copper-plate being duly engraved, it is inked, and an impression taken

on transfer-paper. A good paper, which wetting does not expand, is

needed, and a fatty coating is used in the process. The transfer-paper

impression is laid on the smooth stone, and run through a press. It is

then wetted, heated, and stripped off from the stone, leaving the ink

and fat on its face. The heated fat is softly brushed away, leaving

only the ink-lines. From this reversed impression on the stone, the

printing is performed just as in ordinary lithography. A good transfer

produces from 3000 to 5000 copies. Thus prints from a single

copper-plate can be infinitely multiplied, the printing being,

moreover, much cheaper than copper-plate.'
