In the first number of the "Tonic Solfa Reporter" will be found a selection of hymns marked for "expression' on the plan here proposed. An analysis of those markings has elicited the following principles, which may be of use to the student:-Passages should be marked to be sung softly in which (1) any peculiarly solemn or awe-inspiring thought is expressed; (2) a change from praise to reflection, or (3) from reflection to prayer. Passages should be marked to be sung loudly which express (1) joyful praise, (2) strong desire, (3) ardent gratitude, (4) high resolve, or (5) some inspiring thought.

THE STANDARD SCALE.-A certain note "about midway between the highest and the lowest that can be perceived by the ear" is fixed on by musicians as the standard of PITCH, and the notes arranged upon it, according to the order of the "common mode" or scale already described, are called THE STANDARD SCALE. This note is called c. The second note of the scale is called D; the third ; the fourth F; the fifth o; the sixth A; the seventh B; and the replicate or octave o again. A note something less than half a tone higher than any one of these notes is said to be that note sharpened, as "a sharp." A note something less than half a tone lower than any one of these notes is said to be that note flattened as "B flat." M. Fetis (a wellknown French writer) truly observes that "a sound cannot be altered or substituted for another without ceasing to exist. Do (or c) sharp is no longer Do (or c). It is a mere error so to call it, and it is one of those errors which have tended to render music obscure." But so it is called and we must be content with this warning against the dangers of obscurity. The particular pitch assigned to this note c and consequently to the other notes of its scale is called "concert pitch." The moderns generally fix the sound of c as that which would be produced by 256 vibrations of a sonorous body. The accepted" concert pitch" has been gradually rising to this standard within the last few years, so that Handel's music (unless we lower the key) is sung nearly a tone higher than he meant it to be.

The pitch of the key-note may be given in the heading or title of a tune, thus "key A," "key a," "key в flat," &c. In

"pitching a tune" it is usual to take the upper c' of the standard scale from the TUNING FORK or the pitch pipe to descend to the pitch-note required, and then give its sound to the syllable DOH. Doн, thus fixed, establishes the relative position of all the other notes of a tune. Suppose the "pitch-note" required is D. Then you would take o' from the tuning fork, and run down till you come to D, which you would "swell out" a little, and then sing the same sound to DOH, taking the "chord" afterwards. Thus:| BAG F E : D | -DOH : -i DOH ME | SOH :

If you find any difficulty in singing your ABC backwards, remember that after sounding the c' you have only to spell the words BAG and FED. To pitch в flat, sing the c to the syllable soн, and striking FAH, which will be в flat, call it DOH. The upper c' is used in pitching because the higher sounds are found to be more distinctly and correctly appreciable by the Tuning forks can now be obtained for a shilling or eighteen pence. The wholesale price is 10s. a dozen. We mention this to stimulate our friends to the purchase of these useful instruments. With a small sized one in his pocket the good solfaer is ready to take up a tune-book and make out a tune without the need of any other instrument. After a time he will become, with a little practice to that end, quite inde pendent even of the tuning fork. He will soon learn to recall the pitch note c' at will.

In this summary view, many facts regarding gender, number, and case, are of necessity omitted. They may be found in the works to which reference has already been made. It seems, however, desirable to add, that grammarians recognise in Latin what is called a common gender. Those nouns are said to be of the common gender (c.), which may be applied indifferently, either to a male or a female. Such nouns are hospes, a guest; hostis, an enemy; incola, an inhabitant; parens, a parent; sacerdos, a priest or priestess; testis, a witness; bos, a bull or a cow; canis, a dog or a bitch; lepus, a hare; mus, a mouse, &c.

We wish to make our lessons so simple and plain, that you may thoroughly understand them. In treating of digestion, we showed you that the process begins with taking our food into the mouth. It is there masticated or chewed; in being chewed, it becomes mixed with the saliva of the mouth, until it takes on the character of a soft pulp. It is then swallowed; passes down the oesophagus into the stomach, where it comes in contact with the gastric juice. By the action of this fluid, it is converted into chyme. This chyme passes gradually into the duodenum, where it meets the bile and the pancreatic juice, undergoes a complete chemical change, and reappears in the form of a white milky liquid, known by the name of chyle. This is taken up by the lacteals, and by them poured into the thoracic duct or canal, which is in communication with the greater portion of the absorbent vessels of the body. In this canal the chyle becomes mixed with the lymph, and is thence conveyed into the vein which passes under the left clavicle, and mingling with the venous blood, is carried to the heart and lungs to receive its vital and life-giving properties.

If the food which we eat is thus at last converted into blood, and if it be the blood which builds up every individual part of the body, it is of great importance that our food should be good

and wholesome. The blood can contribute to growth and common egg-shell, which is nothing more than so many layer health only as it exists in a pure and healthy condition.

Or, again, animal structure, with their essential or peculiar properties. suppose a student in the course of dissection should prick his finger, the putri matter thus introduced may so effectually get into his system as to poison the blood and occasion death itself. It follows that a man may wilfully and knowingly induce disease, and injure his system. A drunkard is never a healthy man. Some men may more easily and for a longer period resist the effects of intemperance than others; but that the free use of ardent spirits is prejudicial to health is a truth which all the facts of physiology but too clearly demonstrate. An intemperate man does everything to contravene nature. He is working against God, and against the most beneficent laws of his universe. The great Creator has introduced into the blood all those elements which are adapted to preserve it pure and uncorrupt. What other end can we conceive to be inIvolved in the fact, that in the blood is to be found a certain portion of saline matter? The presence of such an agent in the circulating fluid must be regarded as a beautiful and beneficent provision to prevent its decomposition. Were the blood to decompose in the body, it would cease to possess any vital property; and, deprived of its vitality, it could no longer minister to the nutriment and growth of a single structure.

But the blood is not more dependant on the character of the food which we eat, than on the purity of the air which we breathe. The heart, from which the blood issues in a condition to nourish the body, is situated between the right and the left lung, and with the lungs fills up the whole cavity of the chest, as may be seen by the accompanying cut. Each lung is made up of a countless number of cells or vesicles, which

The blood is a liquid of a beautiful red colour, and of a peculiar odour. In some animals this odour is very marked. Take blood from a cow, and by the smell of the fluid you can tell from what animal it has been drawn. In its living state, the blood is a transparent liquid, Colding in suspension certain little bodies, of which some are colourless, but the greater portion of which have a red colour, and are known by the name of blood-globules. Now, to under. stand how these little bodies are adapted to nourish and build up the body of the strongest and most powerful, we shall try to set before you the compo. nent parts of this precious fluid. Let us open a globule. vein, and take from the body a portion of blood. If we allow it to remain at rest for ten or fifteen minutes, it begins to congeal and take on a more solid form like that of a soft jelly. The fluid has become a solid, and this is the only change which is yet palpable to our senses. After a few hours we and that the clot has a greater degree of consistence, and, as the effect of this contraction, is surrounded with a transparent yellow fluid, which is named serum. Now what is there in this blood to produce this coagulation? Why does it not remain in a fluid state, as when first drawn from the vein? There must be some peculiar law to account for this change. In itself, and as it is seen flowing in the veins of a living creature, it appears a colourless fluid, with minute red particles which give the blood its beautiful scarlet hue; and so long as it is in a fluid state it holds in solution a particular substance called fibrine, which, in its ultimate composition, differs little or nothing from albumen, or the white of an egg. This substance is distributed through the whole body, but is found chiefly in the blood, because the blood, in its course and flow, supplies to every individual part of the complex structure the materials of its growth and development. Take the blood from the living structure, and the fibrine remains no longer in solution. Instead of being diffused, it coagulates and contracts, till it has pressed out the serum by the mutual attraction of its own particles. Now if we look at this clot or congealed blood through a microscope, we shall find that it presents a peculiar arrangement. It is not a mere aggregation or promiscuous accumulation of particles, but a beautiful disposition of fibres crossing one another in every direction. This arrangement may be seen in the

are always full of air derived by inspirations from the atmo sphere which surrounds us. These cells communicate freely the one with the other; and it is in these air-cells of the lungs that the dark venous blood, by coming into contact with the oxygen, is converted into arterial. Impure air, therefore, cannot but be prejudicial to the quality of the blood; and in the degree in which the blood is affected, must the body, with all its peculiar functions, be more or less disordered. No one should sleep in a room into which air has no admission, for i is possible that during the night he may exhaust the whole of the vital air necessary for respiration contained in the apart ment, and the consequence must be suffocation. Nor should we leave our sleeping-room in the morning without throwing open the window and allowing a free current to pass through it. Not only is it important to eat food which is wholesome and easy of digestion, but to breathe the freest and the purest air. No one should choose a house in a crowded, confined, and thickly-peopled neighbourhood. The atmosphere of such a neighbourhood is always more or less impure. Every inspi ration which we take, or every breath which we draw, we take a portion of this air into the lungs, and the blood in its pas sage through the lungs so filled, must to a certain extent be come tainted, and may set up disease in the system. Hence the importance of daily exercise in the open air. The farther we can get away from the smoke, and dust, and surcharged atme
