38 Gaemann, II. C., Frontheim, Norway —Producer.Specimens of chromate of iron, raw and purified by
washing and stamping.
[Chromate of iron occurs as a native ore in several partsof the world, and forms the only available source for theelimination of the important element chromium—in com-
bination generally with potash for the purposes of com-merce. The ore is reduced by being crushed, and after-wards mixed with nitrate of potash and calcined.Chemical combination between the potash and chromicacid then takes place, and the bichromate of potash isseparated from the mass by washing in water, in which itis very soluble. On .evaporation of the solution most bril-liant crystals are developed. This substance is largely em-ployed in the arts of dyeing and calico printing.—R. E.]

Safety spring window, requiring no lines or weights.
[This fastening, while it is perfectly secure against thepossibility of persons from without opening up the sashfor the purpose of entering the house, has also the addi-tional advantage of presenting such an obstacle to childrenopening the window on the inside as to make it a valuableaddition to the windows of nurseries. It is, at the sametime, easily opened by grown persons. It consists of ®spring which is fitted into a recess made in the edge ofthe style of the sash ; the freo end of the spring has con-nected to it a projecting piece which takes into a catchformed in the window frame, by which the sash is im-moveably fixed until the projecting piece is pressed orlifted out of the catch, for winch purpose the end of thespring projects a small distance beyond the surface of thesash-frame, so that by applying the finger to that pro-jection the sash-frame is then free to be moved either upor down as the case may be.]
