ART. XLL— PREPARATION OF CARBURET OF SULPHUR. 
By G. F. MuLLER, Lecturer in the School of Medicine at Rotterdam. 
By the side of the orifice cut in an iron bottle make 
another similar opening. Into the first fit a copper tube 
having a diameter of Om. 01., curved twice at a right an- 
gle ; into the second is introduced a straight tube, having 
the same diameter. The bottle is filled with pieces of 
charcoal recently reddened and of suitable size, so as to 
pass through the tube. After the tubes are adapted, the 
bottle is placed in a furnace and heated, after having sur- 
rounded it by a stone cut in two, so as not to be too much 
inconvenienced by the ascending heat. To the curved copper 
tube is attached a Woulf 's apparatus half filled with water 
and surrounded with a frigorific mixture, and when the 
bottle is properly heated, fragments of sulphur are introduced 
through the straight tube, into which a stopper is immediately 
placed. The sulphur melts, descends, penetrates the fragments 
of charcoal, and when the sulphur is added a little at a time, 
a small amount of gas is obtained and much carburet of sul- 
phur. In this way I have obtained repeatedly, a considerable 
quantity of carburet of sulphur.
