A _regulus_ is a compound of one or more of the metals with sulphur; it is usually brittle, often crystalline, and of a dull somewhat greasy lustre. It is essential that the slag, when solid, shall be so much more brittle than the regulus, that it shall be easy to crumble, and remove it without breaking the latter; and it must not be basic. The effect of fusing a regulus with a basic slag is well seen when _sulphide of lead_ is fused with _carbonate of soda_; the result is a button of metal (more or less pure), and a slag containing sulphides of lead and sodium; and again, if sulphide of lead be fused with an excess of oxide of lead, a button of lead will be got, and a slag which is simply oxide of lead (with whatever it may have taken up from the crucible), or if a sufficient excess has not been used, oxide of lead mixed with some sulphide. When (as is most frequently the case) the desire is to prevent the formation of regulus, these reactions may be taken advantage of, but otherwise the use of a flux having any such tendency must be avoided. A good slag (from which a regulus may be easily separated) may be obtained by fusing, say, 20 grams of ore with borax 15 grams, powdered glass 15 grams, fluor spar, 20 grams, and lime 20 grams; by quenching the slag in water as soon as it has solidified, it is rendered very brittle.

ASSCHE, AMELIE VAN. Portrait painter and court painter to Queen Louise Marie of Belgium. She was born in 1804, and was the daughter of Henri Jean van Assche. Her first teachers were Mlle. F. Lagarenine and D' Antissier; she later went to Paris, where she spent some time as a pupil of Millet. She made her debut at Ghent in 1820, and in Brussels in 1821, with water-colors and pastels, and some of her miniatures figured in the various exhibitions at Brussels between 1830 and 1848, and in Ghent between 1835 and 1838. Her portraits, which are thought to be very good likenesses, are also admirable in color, drawing, and modelling; and her portrait of Leopold I., which she painted in 1839, won for her the appointment at court.

And now at the present time we have twenty or more individuals of this Neanderthal type to compare. The latest discoveries are perhaps the most interesting, because in two and perhaps other cases the man has been properly buried. Thus at La Chapelle-aux-Saints, in the French department of Correze, a skeleton, which in its head-form closely recalls the Gibraltar example, was found in a pit dug in the floor of a low grotto. It lay on its back, head to the west, with one arm bent towards the head, the other outstretched, and the legs drawn up. Some bison bones lay in the grave as if a food-offering had been made. Hard by were flint implements of a well-marked Mousterian type. In the shelter of Le Moustier itself a similar burial was discovered. The body lay on its right side, with the right arm bent so as to support the head upon a carefully arranged pillow of flints; whilst the left arm was stretched out, so that the hand might be near a magnificent oval stone-weapon chipped on both faces, evidently laid there by design. So much for these men of the Neanderthal type, denizens of the mid-palaeolithic world at the very latest. Ape-like they doubtless are in their head-form up to a certain point, though almost all their separate features occur here and there amongst modern Australian natives. And yet they were men enough, had brains enough, to believe in a life after death. There is something to think about in that.
