| A substance best obtained by passing the vapour of bisulphide of carbon over pure alumina, at a bright red heat. |
| Now, when wool moist with bisulphide is heated, it invariably turns yellow. |
| Prepared in this way it contains a small quantity of the unaltered chloride, which can be removed by ether or carbon bisulphide. |
| They are detected by adding chlorine water to the suspected solution and shaking up with carbon bisulphide. |
| In the latter reaction various other compounds, such as carbon dioxide, carbon bisulphide and hydrocyanic acid, are produced. |
| Like the latter, it consisted of two substances, one of which was more soluble in benzine or in carbon bisulphide than the other. |
