A black out- discovered that the leading principles of art are universal, line upon the edges of the shadow injures them very much ; it that they are not confined to one particular branch to the exdestroys the harmony of tone, and, what is very objectionable, clusion of others; but from the moment we take up the pencil the eye is attracted by it. We are obliged to make use of a to commence the outline, the essential beginning of every subline to determine the extent of the part, and its subdivisions ject, we start upon principles which are absolute, and which which contain the extent of tone or colour, and we must have must have their influence in directing us.

In order to understand understood to be a rapid dashing manner, a fatal mistake clearly the extent of these shadows, and to decide where the in hundreds of cases where study and experience have had half-tint commences, and the depth and proportion of all other but little influence. Bold drawing is done with few lines and minor tones, the pupil must look at his copy or model for a seemingly little effort, in a quiet, deliberate, and steady manner, moment or two with half-closed eyes; he will very soon see the producing a resemblance which is recognised, felt, and admired advantage of doing so, as he will thereby be able to say which by all who are interested in it.

Properties.—Sulphur is a brittle solid without taste or smell. When rubbed it emits a peculiar odour, and becomes negatively electrified. It is a very bad conductor of heat, and when a stick of brimstone is held in the hand in contact with the ear it crackles and frequently falls to pieces from the unequal expansion. It is quite insoluble in water, as may be easily seen by examining a piece of brimstone which has been for years in a vessel of water from which a lady's lap-dog drinks. The edges of the roll will be found as sharp as the day when it was first put into the water. Alcohol and ether have but a slight solvent action upon it, but the bisulphide of carbon, CS,, dissolves it freely. Sulphur exists in three modifications. The sulphur which appears in nature when crystallised, is in rhombic octohedra. This same shape is assumed when the bisulphide of carbon, which holds sulphur in solution, is evaporated. These latter crystals, however, are transparent. To procure the second modification, sulphur is melted, and when it is covered with a film
w on cooling, a hole is broken through the crust, and the sulphur which is still liquid is poured out; the under surface of the film and the sides of the crucible will be found covered with long needleshaped transparent crystals belonging to the oblique prismatic form, and having a specific gravity of 1.98, whereas that of th3 native sulphur is 2.07. These crystals soon become opaque, and when touched crumble into powder, the particles of which are found to be crystals similar to those of native sulphur. Thus sulphur is “ dimorphous," or capable of crystallising in two different systems. The third and more remarkable variety is produced by heat. At 1150 sulphur begins to melt, forming a pale yellow mobile liquid. Upon raising the temperature its colour

Sulphuric Trioxide (symbol, so, ; combining weight, 80; density, 40).—This substance may be prepared by passing a mistare of sulphurous acid gas and oxygen through a tube containing spongy platinum heated to 180° Cent. In the pores of the platinum the sulphurous gas becomes oxidised into sog, which passes out of the tube in white vapours, and condenses in a receiver into fine silky needles.
This substance possesses no acid properties until it combines with water, which it does with violence, forming sulphuric acid.
When the vapour of sulphuric trioxide is passed through a red-hot tube it is decomposed into 2 volumes of sulphic dioxide and 1 of oxygen, thus-So, = SO + 0.
