To bring the richer and poorer materials under the same conditions for the assay, a small weight, say 1 gram of the richer, and a larger weight (5 or 10 grams) of the poorer, substance is weighed up. A method is then adopted which will concentrate the whole of the metal (either during or after solution) in a product which need not necessarily be pure. The work on this product is comparatively easy. In separating small quantities of a substance from a large bulk of impurities, the group separations must not as a rule be too much relied on. Very large precipitates carry down small quantities of bodies not belonging to the group, more especially when there is a tendency to form weak double compounds. The re-dissolving and re-precipitating of bulky precipitates should be avoided. |
MY DEAR MISS BROOKE,--I have your guardian's permission to address you on a subject than which I have none more at heart. I am not, I trust, mistaken in the recognition of some deeper correspondence than that of date in the fact that a consciousness of need in my own life had arisen contemporaneously with the possibility of my becoming acquainted with you. For in the first hour of meeting you, I had an impression of your eminent and perhaps exclusive fitness to supply that need (connected, I may say, with such activity of the affections as even the preoccupations of a work too special to be abdicated could not uninterruptedly dissimulate); and each succeeding opportunity for observation has given the impression an added depth by convincing me more emphatically of that fitness which I had preconceived, and thus evoking more decisively those affections to which I have but now referred. |

Just as the gaseous nebulae radiate heat into space and condense, so must the stars, with this difference: the nebulae are highly rarified bodies, with surfaces enormously large in proportion to the heat contents; and the radiation from them must be relatively rapid. In fact, some of the nebulae seem to be so highly rarified that radiation may take place from their interiors almost as well as from their surfaces. The radiation from a star just formed must occur at a much slower rate. The continued condensation of the star, following the loss of heat, must lead to a change of physical condition, which will be apparent in the spectrum. It should pass from the so-called helium group, to the hydrogen, or Class A group, not suddenly but by insensible gradations of spectrum. In the Class A stars the hydrogen lines are the most prominent features. The helium lines have disappeared, except in a few stars where faint helium remnants are in evidence. The magnesium lines have become prominent and the calcium lines are growing rapidly in strength. The so-called metallic lines, usually beginning with iron and titanium lines, which have a few extremely faint representatives in the last of the helium stars, become visible here and there in the Class A spectra, but they are not conspicuous. | ||
