Elements of chemistry ... n the apparatus is ready, and the iron tube is at awhite heat, the stopper a is to be removed, and pieces ofsulphur dropped in, and the stopper instantly returned toits place.

The sulphuret of carbon, being condensed by the coldtube, flows along into the flask, and sinks in the water itcontains. 405. A more simple method of producing the sulphuretof carbon, where it is designed to make it in quantities, isthe following: CARBON AND SULPHUR. 221 A cast iron cylinder is procured, having a cover throughwhich pass the tubes b, c, Fig. 74. The cylinder is to becoated with clay in the manner above described for the irontube, and then filled with charcoal, the tube b, being in itsplace as shown by the figure. The cylinder is then to beplaced in a furnace, and heated to redness, and then the Fig. sulphur introduced through the tube, 5, the aperture ofwhich must be immediately closed. The melted sulphur,passing down the tube to the bottom of the cylinder, isthere converted into vapor, and passing through the ignitedcharcoal combines with it, and rises by the iron tube c, intothe glass tube, e, along which it is condensed. The tube dleads from a cistern of water, which is allowed in smallquantities to run in a trough containing the glass tube, andfrom which it is conducted by the string h, to the dish sulphuret as it is formed, passes down the tube f intothe vessel n, this being half filled with pounded ice. Thewaste pipe m, conducts away any superfluous gas which isgenerated during the process. Whenever all is prepared, as above described, the intro-duction of small quantities of sulphur by the tube b, willinsure the production of the compound in question, so longas any charcoal remains in the cylinder. It is apt, how-ever, to contain some impu
