DANIELL, Esq. F. R. S. M. R. I. THE resinous substance, the properties of which I shall en deavour to describe, was sent to me for examination by my friend Mr. H. B. Ker. Its history is this.-A lady brought from India a work-box that had been varnished; the var nish looked particularly clear, and had borne the heat of the climate without cracking or changing colour. Some distinguished artists saw it, and admired its peculiar beauty. The lady sent to the Rajah from whom she had originally procured it, and he remitted her an hamper full of stone bottles, containing the varnish, informing her that it was employed in all his ornamental work, and that it was used just as it was extracted from the tree from which it was procured, by incision. The name of the tree he unfortunately omitted to send. Its original consistence is that of cream, and when spread upon white paper, it dries quickly, is colourless, and of a brilliant polish, never cracking when exposed to the sun. She specimens which were sent over were put into the bottles upon being collected, and the precaution was taken of filling their necks with water. Notwithstanding this, their contents had become perfectly solid. In the state in which I received it the resin was opaque, except just at the exterior coat, which was slightly translucent, of a very pale green colour, conchoidal fracture, and of a lustre intermediate between resin and wax. It was tasteless, easily pulverized, and inodorous. It inflamed with violence, and deposited much carbonaceous matter whilst burning, and diffused a pleasant aromatic smell. Its specific gravity was 1033. Two hundred grains of it pulverized were boiled for three hours in half a pint of distilled water it was then allowed to stand for twelve hours. The resin, on being collected and dried, had lost in weight only 0.8 of a grain. The infusion was reduced by evaporation, and it then presented the following properties. Muriate of tin threw down a dark brown powder; solution of chlorine in water produced a yellow precipitate; and muriate of alumina, when boiled with it, became cloudy. These are the indications of extractive matter. It was then subjected to the action of cold alcohol. Much of it was dissolved, but an insoluble white powder remained, and did not decrease in quantity by boiling. The same white substance was left when the resin was acted upon by ether and spirits of turpentine. It was collected upon a filter well washed with alcohol, dried at a gentle heat, and then weighed 75 grains. : The alcoholic solution was colourless, and had a very peculiar smell, resembling that of the bruised stalks of green vegetables water instantly precipitated the resin. It was evaporated at a very gentle heat, and a light yellow transparent resin remained, which weighed 127 grains. The same resin was collected from the ethereal solution. The undissolved residue was inflammable, and burned with much smoke and a pleasant smell. It possessed no elasticity to the touch, but felt like powdered starch. It was not affected by any temperature under 360° of Fahrenheit's scale, when it began to fuse; and melted by a continuation of the heat into a deep brown transparent resin. The resin which had been dissolved by alcohol began to soften at 100°, and the original resin at 220°. The specific gravity of the most fusible was 932; of the least fusible 1000. |
