It parts with its third ducing the change can be further tested, so atom as in the mercury experiment, and thus as to render it certain that ozone only has loses its distinctive peculiarity. Thus we been at work. If air which colours the test- might be led to anticipate the results which papers can be found to lose the property come next to be considered. after being heated, the change can only be due to ozone, because nitrous and nitric acid (which have the power of colouring the test-papers) would not be removed by the heat, whereas ozone is changed by heat into

Oxygen.

Once we are certain that ozone exists in the air, we must recognize the fact, that its presence cannot fail to have an important bearing on our health and comfort; for ozone is an exceedingly active agent, and cannot exist anywhere without setting busily to its own proper work. What that work is, and whether it is beneficial or deleterious to ourselves, remains to be considered.

In the first place, ozone has immense power as a disinfectant. It decomposes the products emanating from putrefying matter more effectually than any other known element. Perhaps the most striking proof ever given of its qualities in this respect is that afforded by an experiment conducted by Dr. Richardson a few years ago.

[ocr errors]

He placed a pint of blood taken from an ox in a large wide-mouthed bottle. The blood had then coagulated, and it was left exposed to the air until it had become entirely redissolved by the effects of decomposition. At the end of a year the blood was put in a stoppered bottle, and set aside .for seven years. The bottle was then taken from its hiding-place," says Dr. Richardson, "and an ounce of the blood was withdrawn. The fluid was so offensive as to produce nausea when the gases evolved from it were inhaled. It was subjected by Dr. Wood and myself to a current of ozone. For a few minutes the odour of ozone was destroyed by the odour of the gases from the blood; gradually the offensive smell passed away; then the fluid mass became quite sweet, and at last a faint odour of ozone was detected, whereupon the current was stopped. The blood was thus entirely deodorized; but another and most singular phenomenon was observed. The dead blood coagulated as the products of decomposition were removed, and this so perfectly, that from the new clot that was formed serum exuded. Before the experiment commenced, I had predicted on theoretical grounds that secondary coagulation would follow on purification; and this experiment, as well as several others afterwards performed, verified the truth of the prediction."

It will of course be understood that ozone in thus acting as a disinfectant is trans

Oxone has certain work to do, and in doing that work is transmuted into oxygen. It follows, then, that where there has been much work for ozone to do, there we shall find little ozone left in the air. Hence, in open spaces where there is little decomposing matter, we should expect to find more ozone than in towns or cities. This accords with what is actually observed. And not only is it found that country air contains more ozone than town air, but it is found that air which has come from the sea bas more ozone than even the country air, while air in the crowded parts of large cities has no ozone at all, nor has the air of inhabited rooms.

So far as we have gone, we might be disposed to speak unhesitatingly in favour of the effects produced by ozone. We see it purifying the air which would otherwise be loaded by the products of decomposing matter, we find it present in the sea-air and the country air, which we know to be so bracing and health-restoring after a long residence in town, and we find it absent just in those places which we look upon as the most unhealthy.

Again, we find further evidence of the good effects of ozone in the fact, that cholera and other epidemics never make their dreaded appearance in the land when the air is well supplied with ozone- or in what the the meteorologists call the r ozone-periods." And though we cannot yet explain the circumstance quite satisfactorily, we yet seem justified in ascribing to the purifying and disinfecting qualities of ozone our freedom at those times from epidemics to which cleanliness and good sanitary regulations are notedly inimical.

But there is a reverse side to the picture. And as we described an experiment illustrating the disinfecting qualities of ozone before describing the good effects of the element, we shall describe an experiment illustrating certain less pleasing qualities of ozone before discussing the deleterious influences which it seems capable of exerting.

Dr. Richardson found that when the air of a room was so loaded with ozone as to be only respirable with difficulty, animals placed in the room were affected in a very singular manner. "In the first place," he says, "all the symptoms of nasal catarrh and of irritation of the mucous membranes of the nose, the mouth, and the throat were rapidly induced. Then followed free se

other similar diseases seem peculiarly associated with the ozone-periods, insomuch that eighty per cent. of the deaths occurring from them take place on days when ozone is present in the air in larger quantities than usual. Catarrh, influenza, and affections of the bronchial tubes, also affect the ozoneperiods.

The breathing was certain diseases, bring with them their own greatly quickened, and the action of the forms of disease. Apoplexy, epilepsy, and heart increased in proportion." When the animals were suffered to remain yet longer within the room, congestion of the lungs followed, and the disease called by physicians "congestive bronchitis " was set up. A very singular circumstance was noticed also as to the effects of ozone on the different orders of animals. The above-mentioned effects, and others which accompa- We see, then, that we have yet much to nied them, the description of which would learn respecting ozone before we can probe out of place in these pages, were devel-nounce definitely whether it is more to be oped more freely in carnivorous than in her- welcomed or dreaded. We must wait unbivorous animals. Rats, for example, were til the researches which are in progress have much more easily influenced by ozone than been carried out to their conclusion, and rabbits were. perhaps even further modes of inquiry will have to be pursued before we can form a definite opinion.

The results of Dr. Richardson's experiments prepare us to hear that ozone-peri

A LARK'S FLIGHT.

IN the quiet city park,

Between the dawn and the dark,

Loud and clear,

That all may hear,

Sings the lark.

Beyond the low black line

Of trees the dawn peeps red;
Clouds blow woolly and fine
In the blue lift overhead;
Out of their is shaken

A fresh and glistening dew,
And the city begins to waken,

And tremble through and through.
See! (while through street and lane
The people pour again,

And lane and alley and street
Grow hoarse to a sound of feet),
Here and there

A human shape comes, dark.
Against the cool white air,
Fitting across the park;

While over the dew-drench'd green,
Singing his "Hark, oh! hark!"
Hovering, hovering, dimly seen,
Rises the lark.

"Mystery! O mystery!"

Clear he sings to lightening day. "Mystery! O mystery! Up into the air with me;

Come away, come away!"

Who is she that, wan and white,
Shivering in the chilly light,
Shadeth weary eyes to see
Him who makes the melody?

[merged small][merged small][ocr errors]

Who is he, the stooping one,
Smiling coldly in the sun;
Arms behind him lightly thrown,
Pacing up and down alone?
'Tis the great philosopher,
Smoothly wrapt in coat of fur,
Soothly pondering, manwit wise,
At his morning exercise.

He has weigh'd the winds and floods;
He is rich in gather'd goods;
He is crafty, and can prove

God is Brahma, Christ, nor Jove;
He is mighty, and his soul
Flits about from pole to pole,
Chasing signs of God about,
In a pleasant kind of doubt,—
What, to help the mystery,
Sings the lark to such as he?

The lark cries,

"Praise to Nature's plan!
Year on year she plies
Her toil of sun and skies,

Till the beast flowers up in man;

Palid and proud stalks he,

Lord of effect and cause,

Till the voice in the cloud cries, 'Pause!'

And he pauses bitterly

On the verge of the mystery."

O, loud and clear, that all may hear,

Rising higher with "Hark, oh! hark!" Higher, higher, higher, higher, Quivering as the dull red fire

Of dawn grows brighter, cries the lark;
And they who listen there while he
Singeth loud of mystery,
Interpret him in undertone
With a meaning of their own,
Measuring his melody
By their own soul's quality.

Tall and stately, fair and sweet,
Walketh maiden Marguerite,
Musing there on maid and man,
In pale mood patrician,

To all she sees her eyes impart
The colour of a maiden heart;
Heart's chastity is on her face;

She scents the air with nameless grace,
And where she goes, with heart astir,
Colour and motion follow her.

What should the singer sing

Unto so sweet a thing,

But

"Oh! my love loves me!

And the love I love best is guarding the nest,
While I cheer her merrily,

Come up high! come up high! to a cloud in the sky!

And sing of your soul with me!"

Elbows on the grassy green,
Scowling face his palms between,
Yonder gaunt thief meditates
Treason deep against his mates;
For his great hands itch to hold
Both the pardon and the gold.
Still he listens unaware,
Scowling round with sullen stare,
Gnawing at his under lip,
Pond'ring friends and fellowship,
Thinking of a friendly thing
Done to him in suffering,
And of happy days and free
Spent in that rough companie;
Till he seeks the bait no more,
And the lark is conqueror.

For the lark says plain,

"Who sells his friend is mean; Better hang than drain

The poison'd gold of the queenA whip for the rogue who'd tell The lives of his mates away Better the rope and the cell! Better the devils of hell!

Come away! come away!"

O lark! O lark!

Up, up! for it is light,

The souls stream out of the dark,
And the city's spires gleam bright;
The world, the word, is awake again,
Each wanders on his way,
The wonderful waters break again
In the white and perfect day.
Nay! nay! descend not yet,
But higher, higher, higher,
Up through the air, and whet
Thy wings in the solar fire!
There, hovering in ecstasy,
Sing, "Mystery, O mystery!'

O lark! Olark! hadst thou the might
Beyond the cloud to wing thy way,
To sing and soar in wondrous flight,
It might be well for men this day.
Beyond that cloud there is a zone,
And in that zone there is a land,
And in that land, upon a throne,
A mighty Spirit sits alone,

With musing cheek upon his hand.
And all is still and all is sweet
Around the silence of his seat, -
Beneath the waves of wonder flow, -
And coolly on his hands and feet

The years melt down as falling snow.

O lark! O lark!

Up! for thy wings are strong; While the day is breaking, And the city is waking,

Sing a song of wrong -
Sing of the weak man's tears,

Of the strong man's agony,
The passion, the hopes, the fears,
The heaped-up pain of the years,
The terrible mystery.

O lark! we might rejoice,

Couldst reach that distant land, For we cannot hear His voice,

And we often miss His hand;
And the heart of each is ice.

To the kiss of sister and brother;
And we see that one man's vice
Is the virtue of another;
Yea, each that hears thee sing
Translates thy song to speech,
And lo! the rendering

Is so different with each.
The gentle are oppressed,
The foul man fareth best,
Wherever we seek, our gain
Is bitter, and salt with pain.
In one soft note and long
Gather our sense of wrong
Rise up, O lark! from the clod,
Up, up, with soundless wings, -
Rise up to God! rise up, rise up, to God!
Tell Him these things!

Now, as noblest in rank of our Sun's great children, see,

Over dim waters and woods and hills, in the clear dark night-sky,

Jupiter hangs like a royal diamond, throbbing with flame.

Still in our starry heav'n the Pagan Gods have their station;

Only, in sooth, as words: and what were they ever but words?

Lo, mankind hath fashion'd its thoughts, its hopes, and its dreamings,

Fashion'd and named them thus and thus, by the voice of its bards,

Fashion'd them better or worse, from a shallower insight or deeper,

Names to abide for a season, in many mouths or in few;

Each and all in turn to give place, be it sooner or later.

SONNET.

W. A.

BY THE AUTHOR OF "LADY GRACE."

POOR drifted flower, which this unthinking sea
Sends where it will, to any passer's foot,
Do memories of sweet earth about thy root
Haunt thee? and when the salt spray shudders
thee,

Hast thou a thought of dew? and when the light

Slopes through thee to the cold unanswering sand,

Do thrills and mockeries of growth expand

Thy useless veins? Day moulders into Night As thou to nothing; but great Morn shall stand And quicken all the unforgetful land

With glory, and the ready sky with bliss, Thou only unconcerned beneath a kiss Which wakes the world; thou, like a homeless heart,

Movest no more, but diest where thou art!

Good Words.
