Behaviour of Borax towards Zinc Salts in Aqueous Solution.-Friedrich Borchers. - When cold saturated borax solutions are precipitated with zinc salts (sulphate or chloride) the amount of boric acid entering into the pre- cipitate increases with the concentration of the substances. The best yields of zinc borate are obtained if the solution of zinc salt is poured into the borax solution, and the borax is present in slight excess. Zinc sulphate or chloride must be used in as concentrated a form as possible, or in the solid state. From cold saturated solutions of borax the highest percentage of borax precipitated as zinc borate was 38.6 per cent. With supersaturated borax solution or with solid borax, zinc borate precipitates containing up to 83 per cent of the boric acid in the solution can be obtained. For pure borax solutions an excess of the precipitating reagent causes a diminished yield of zinc borate. Thus zinc borate is soluble in zinc sulphate, complex salts being formed. Other salts also act as solvents; e.g., sodium chloride and magnesium chloride. Manganese chloride and sulphate also precipitate boric acid. By the addition of caustic soda OH-ions were introduced; these lowered the H-ion concentration of the zinc sulphate, and thus raised the borate concentration, but at the most only 70 per cent of the borax in the solution could be pre- cipitated. If the zinc borate is removed by filtration and the filtrate is neutralised with caustic soda, and again pre- cipitated with zinc salt solution, by repeating the process several times 94 per cent of the borax can be separated from the solution. Only very little borate is formed when free carbon dioxide is present in the cold saturated borax solution; if sodium carbonate is present the amount of precipitate is increased, but does not reach that obtained with an equivalent quantity of caustic soda. If caustic soda is added to solutions containing soda the solvent action of the zinc carbonate is diminished, and the tion of borate is increased. In borax solutions containing other salts, e.g., NaCl and Na2SO4, besides Na2CO3, an excess of zinc salt is necessary in order to precipitate the greatest possible amount of borate.
regarded as dissolved water and tremolite as a solid solution. A diopside from altered limestone contained I per cent of water, and behaved in practically the same way. Kupferrite and a specimen of beryl contained 3.8 and 2.5 per cent of water, which they gave up only very slowly at a comparatively high temperature (400-800°) without losing their homogeneity. It was not found possible to remove the water altogether. All these minerals show important resemblances to zeoliths, but differ from them in one way, viz., they do not give true equilibrium with water vapour at a low temperature. Fresh analyses show that all amphiboles contain water and also hornblendes, though in smaller quantity. Probably the amphiboles contain dissolved water as a characteristic constituent, and are
Quartz as a Geological Thermometer.-Fred Eugene Wright and Esper S. Larsen.-Quartz is capable of giving at least one, and possibly two, points for the geological thermometer scale, for when heated to 575° it undergoes an enantiotropic transformation into a second phaseMugge's 3 quartz-while at 800° it is no longer stable at the ordinary pressure, but passes over into cristoballite. The transition-point of and 3 quartz is determined by observing the sudden change of double refraction, circular polarisation, and coefficient of expansion at this temperature. The most accurate optical determinations fix the transition temperature at 575° ±2. Crystallographic experiments enable a quartz which has been heated above 575° to be distinguished from one which has never reached this temperature.
Binary System of Alumina with Silicic Acid, Lime, and Magnesia.-E. S. Shepherd and G. A. Rankin.— Thermic experiments show that there is only one compour.d of aluminium and silicic acid (Al2SiO5) which is stable in contact with the melt; this is the mineral sillimanite. forma-Andalusite and cyanite both go slowly over into sillimanite at 1300°. Four different compounds of aluminium and lime exist, viz. :-3CaO.Al2O3, 5ČaO.3Al2O3 of melting-point 1383°, CaO.Al2O3 of melting-point 1592°, and 3CaO.5Al2O3. The first and last of these have no true melting-point, but the former is completely fused at 1555° and the latter at about 1730°. Two of these compounds, 5CaO.3Al2O3 and 3Ca0.5Al2O3, have each an unstable form, while 3CaO.Al2O3, and probably 3Ca0.5Al2O3, are unstable at the melting-point. It is probable that only 3CaO.Al2O3 and 5Ca0.3Al2O3 are present in Portland cement. Only one compound of alumina and magnesia exists, viz., MgO.Al2O3. Probably in the system MgO-CaO no compounds are present.
Silver-sodium Alloys.-E. Quercigh.-From the study of the solidification curves of silver sodium alloys it is found that the two metals are miscible in all proportions in the liquid state. No compound is formed. There is a eutectic situated quite close to the sodium axis. The shape of the curve of the primary crystallisation shows that there is a tendency to form a compound, but when formed it must dissociate in the melt. Silver can dissolve up to 13 atoms per cent of sodium in the solid state.
Phosphorus Oxychloride as a Cryoscopic Solvent. -P. Walden.-Determinations of the freezing-point of pure phosphorus oxychloride show that this constant is incorrectly stated even in the standard text-books; it is neither 1782° nor -15°, but lies above o°. By fractional distillation and crystallisation a melting-point of +125° can easily be reached. Its cryoscopic constant is K = 76.8 (as compared with 69 given by Oddo). Using these new constants the molecular weights of iodine chloride, iodine cyanide, nitric acid anhydride, perchloric acid anhydride, and perosmic acid anhydride (osmium tetroxide) were

Rôle of Water in Tremolite and some other Minerals.-E. T. Allen and J. K.

Thus the WEDNESDAY, 4th.-Royal Society of Arts, 5. water is not chemically bound, although the powdered mineral is not completely dehydrated at 900°. It must be
