2. In _moderate towns_, from 1-25 to 1-28.

3. In _small villages_ and the _open country_, from 1-35 or

1-40, to 1-50 or 1-60.

Thus, in London one person in 20 of the whole population dies annually;

while in the healthiest villages and open country, the rate of annual

mortality is not more than 1 in 55 or 60.

_Atmosphere of Theatres_.

Lavoisier, the French chemist, found, in a theatre, that, from the

commencement to the end of the play, the oxygen, or vital air, was

diminished in the proportion of from 27 to 21, or nearly one-fourth, and

was in the same proportion less fit for respiration than before.

_Butterflies_.

In June, 1826, a column of butterflies, from 10 to 15 feet broad, was

seen to pass over Neuchatel, in Switzerland. The passage lasted upwards

of two hours, without any interruption, from the moment when the

butterflies were first observed.--_Brewster's Journal_.

_Water Plant_.

A shrub has been discovered in our new Indian countries, from whose

stem, when divided, there issues a copious vegetable spring of limpid

and wholesome water. The natives know this well, and hence we rarely

meet with an entire plant. It is a powerful climber, and is quite new

and nondescript.--_Letter from India_.

_Malaria and Fevers_.

It is notorious, that, in the last autumn, the remittent fevers in

various parts of the country amounted to a species of pestilence, such

as has scarcely been known in England from this cause since the days of

Dr. Sydenham. Wherever ague had existed, or ever had been supposed

possible, in those places was this fever found; so that in all the

well-known tracts in Lincolnshire, Norfolk, Suffolk, Kent, Essex,

Sussex, Hampshire, &c. there was scarcely a house without one or more

inhabitants under fever, with a considerable mortality. In the parish of

Marston, in Lincolnshire, it amounted to 25 in 300 inhabitants. The same

fevers were extremely abundant in various parts of the outskirts of

London, as also in the villages or towns which are connected with it,

within a range of from six to ten miles. This was the case throughout

the range of streets or houses from Buckingham Gate to Chelsea; in which

long line, it is said, that almost every house had a patient or more

under this fever, though these were mistaken for typhus, or at least

thus misnamed. Then it was also about Vauxhall and Lambeth; and to a

great extent among all that scattered mixture of town and country which

follows from Whitechapel, from Bishopsgate, &c., and very particularly

along Ratcliffe-Highway to an indefinite range along the river. In

Lewisham there were in one house nine patients under this fever, which

proved mortal to one. We may also enumerate Dulwich, especially subject

to this disorder, Fulham, Ealing, and the several other villages along

the Thames, as far as Chertsey; and even Richmond, where, as at

Lewisham, there was one house where ten individuals at one time were

suffering under this disease. Whatever was the pestilence last year, it

promises to be much greater in the present one. This is easily judged

from the manner in which the season has set in, but still more decidedly

from the extraordinary prevalence of ague in the spring; since that

which was intermittent fever then, will be remittent in the autumn, or

rather, there will scarcely be a definite season of vernal intermittent,

but the remittent will commence immediately, increasing in extent and

severity as the summer advances, and promising to become, in the autumn,

the greatest season of disease that England has known for this century.

Dr. Macculloch attributes this alarming increase to _malaria_, on

the production and propagation of which he has recently published an

essay, the leading argument of which is, "that as the quantity of the

poison which any person can inspire is necessarily small, and as this

small quantity can be produced by a small marshy spot as well as a large

one, it is the same, as to the production of the disease, whether the

marsh is a foot square or a mile, provided the exposure be complete;

while also any piece of ground where vegetables decompose under the

action of water is virtually a marsh, or must produce _malaria_."

_Acclimatizing Plants_.

A Mr. Street, of Biel, in East Lothian, has recently made some

successful attempts at acclimatizing, or giving to exotic plants greater

powers of withstanding cold than they had when first introduced. By

planting in situations well drained from superfluous moisture, under

circumstances where rapid growth was rendered impracticable, and in a

garden admirably adapted to the object from its position, he has

succeeded in naturalizing, in latitude 56° N. plants which have not yet

been known to endure the winters even of the parallel of

London.--_Quarterly Journal of Science_.

In a table kept at Sydney by Major Goulburn, from May 1821 to April

1822, the thermometer never rose above 751/2° and never lower than 54° of

Fahrenheit.

_Bronzing Tin_.

To obtain complete success in bronzing medals of tin, the two following

solutions must be employed:--

The first, which is merely a wash, is composed of 1 part of iron, 1 part

of sulphate of copper, and 20 parts, by weight, of distilled water. The

second solution, or bronze, is composed of 4 parts of verdigris and 16

parts of white vinegar. The medals should be filed, and well cleaned

with a brush, earth, and water; and being well wiped, should have a

portion of the first solution passed slightly over their faces, by means

of a brush, and then be wiped; this gives a slight grey tint to the

surface, and causes the ready adhesion of the verdigris, &c. The second

solution is then to be rubbed over by means of a brush, until they have

acquired the deep red colour of copper; they are then to be left an hour

to dry, after which they are to be polished with a very soft brush and

rouge, or the red oxide of iron in fine powder. The polish is to be

completed by the brush alone, the medals being passed now and then over

the palm of the hand.--_Verly_.

_Culture of Celery_.

Mr. Knight, president of the Horticultural Society, has found that by

keeping the ground in which celery was planted, constantly wet, it grew

by the middle of September to the height of five feet, and its quality

was in proportion to its size. Mr. K. also recommends planting at

greater distances than is usually the case, and covering the beds, into

which the young seedlings are first removed, with half-rotten dung,

overspread to the depth of about two inches with mould; under which

circumstances, whenever the plants are removed, the dung will adhere

tenaciously to their roots, and it will not be necessary to deprive the

plants of any part of their leaves.--Mr. Wedgewood also states, that

good celery may be readily obtained by transplanting seedling plants

that have remained in the seed bed, till they had acquired a

considerable size.--_Quarterly Journal_.

_Dwarfs_.

Richard Gibson, the dwarf, married Anne Shepherd, another dwarf. Each of

them was only 3 feet 10 inches high. They had nine children, of whom

five lived to maturity, and were of a proper size. Richard, the father,

lived to the age of 75, his little widow to that of 89. It is

presumptive, that the dwarf size is only occasioned by some obstruction

during _utero_--gestation. The full size of the children proves

that nature does not perpetuate abortions.

_Cruelty and Epicurism_.

A sharp axe, on the principle of a punch, is used in _slaughtering

bullocks_, not to kill them at once, but to cut a circular hole in

the skull, into which a stick is introduced _to stir up the

brains_, for the purpose of making the meat more tender! The throat

is not attempted to be cut till after the infliction of this torture,

horrible even to think of, which instantly causes the most convulsive

agonies, such as are never seen in death of any other kind.

Lord Somerville's mode of _pithing_ animals, brought forward with

the most humane views, is a _horrible operation_. The body is

deprived of sensation, _while the living head rolls its eye in agony

on its tormentors_.--_Sir Everard Home_.
