ACBTANILIDE IX HYDROGEN PEROXIDE. 159 



I. Round the outer edge small globules of amoi-phous sulphur had 

 been fii-st deposited. 



II. Within the deposit of globules monoclinic sulphur had crystal- 

 lised, the needles radiating from centres toward the centre of the 

 ■watch glass. 



IIJ. In the middle of the watch glass octahedral sulphur had been 

 deposited, the number of crystals being comparatively small. Around 

 each crystal or group of crystals was a clear space, and where an 

 octahedral ciystal had been deposited among the monoclinic crystals, a 

 clear space surrounded the crystal, indicating that the more stable 

 foj-m was growing at the expense of the less stable, the octahedral form 

 being at ordinary temperatures less soluble than the prismatic variety. 

 The watch glass with the deposit of sulphur crystals is capable of 

 being used as a lantern slide, giving a good lecture illustration of 

 the fact that the different phases of sulphur can be thus obtained from 

 the same solution.
