The daylight is not sufficiently intense; we cannot focus it so as to be passed through the galleries of mines. In your opinion, would the experiment be better conducted by placing the light above the shaft, or at the bottom of the shaft-It would depend on the depth and size of the shaft.

Assume 200 yards in deptn?—In such ease above; you get at the materials and apparatus for forming the light better; the distance of 200 yards has very little effect in diminishing the light; reflected light does not obey the same laws as radiated light; radiated light diminishes as the squares of the distances, but reflected light does not; this is contrary to received opinions, but I am satisfied it is corect, from the observations I have lately made.

You have not supposed any difficulties in the application of this light, beyond those already stated, which the Committee understand to be the interruptions occasioned by stoppings or trap-doors in the mines, or the extreme sub-division of the reflected light? I have: there are others, but I think of

minor importance, which can only be justly appreciated in practice.

The shafts of the mines are placed at right angles, that is, they are driven along, and they begin at the further end, and then work upwards; is there any difficulty in transmitting the light at right angles?-Not any difficulty whatever; you may transmit the light in any angle you please; it may first be thrown down a shaft, and then sent into any angle, upwards or downwards, or on one side or on another.

Suppose there be a space of two or three feet left on one side, or both sides, of the carriages conveying the minerals along the galleries, the light might be transmitted independently of the space occupied by the carriages?—Certainly.

The atmosphere which surrounds our earth is the first object to which our attention should be directed. This is the vehicle of the moisture, which, whether it fall in the form of rain or dew, run in streams or issue from springs, is absolutely essential to the success of the farmer's labor. It is also, as we shall presently see, important to him on other accounts.

The greater part of the atmosphere is made up of a mixture of substances, each of which has the same mechanical properties as the whole mass. These air-like name of Gases. substances are known to chemists by the

Of these gases, two make up by far the greater portion of atmospheric air, and exist in it in the proportion of about 4 to 1.That which is the largest in quantity and makes up nearly 4-5ths of the whole atinosphere, is called, in the Essay of M. Puvis, by the name of Azot, but is more usually gen. known in English by the name of Nitro

This substance, although in the largest proportion, is the least important of the gases in its chemical effects. It does not aid in supporting the life of animals, nor in maintaining the burning (combustion) of inflammable bodies.

The part of the atmosphere which is abcalled by the name of oxygen, and nearly solutely necessary for these purposes, is makes up the remaining fifth part of atmospheric air. In its support of life it al

Carbonic acid is always found in small quantities in the atmosphere, to which it is furnished by the breath of animals and the fumes of burning bodies. It is, when in considerable quantities, fatal to the life of animals, but is prevented from accumulating to an injurious extent in consequence of its being taken up by water; it is therefore dissolved, in proportions about equal to those in which it is formed by rivers, lakes, the ocean, and the moisture of the soil.

Lime is familiarly known by the same name that is generally used by chemists.It is obtained by the aid of heat from rocks which go by the name of limestones.These are combinations of lime with carbonic acid, which is fixed in them by chemical attraction, but which, when driven off by heat, takes the same form as the air of the atmosphere, or becomes a gas. This gas from this circumstance has been called fixed air, by which name it is often known when causing the sparkling and froth of cider and beer. The principal part of lime stone is therefore called by chemists carbonate of lime. Carbonate of lime is also found in shells, both those of living animals and those which exist in the ground in a fossil state. In the former it is mixed with animal matter which is more or less sepa

Water exists in the atmosphere in the form of vapour. The great source of this vapour is the extended surface of the ocean, and it is governed by a mechanical law, by which it is continually tending to distribute itselt uniformly over the whole surface of the earth. It may thus exist in as large quantities over the surface of the dryest land as over that of the ocean itself. The tendency to equal distribution is continually counteracted by the changes in the sensible heat (temperature) of the at-cessary to know the names of two, namely, mosphere, and of the surface of the earth, which follow the alternations of day and night, and the vissitndes of the seasons.By these alternations and changes, the va pour is caused to fall (precipitated) in the form of rain, snow, hail, dew, or white frost, according to circumstances. Assuch The earth which the chemists call by the changes of temperature are more frequent name of silex or silica, is found almost pure on the land than on the ocean, the water in flint and rock chrystal; it is also almost which falls on the former in either of these pure in sharp colourless sands, and is by far forms is greater in quantity than that the larger part of sands of every description. which falls on equal surfaces of the latter.

rivers.

Water has been found by chemists to be a compound substance, made up of two elements. One of these, which forms 8-9ths of its weight, is the gas already mentioned under the name of oxygen; the other, a peculiar gas, known by the name of hydrogen.

Lime is a substance very different in its characters from the two earths we have previously spoken. When prepared by heat from any of the original forms of its carbonate, it retains their shape unaltered, but may have its color changed, and always loses considerable in weight. It is now acrid, caustic and corrosive, and allkaline. Of these the most important is, that it unites with acids to form compounds included in the general class of salts.
