stances, it is readily acted upon by the gas. It loses its wax 

 character, becomes gum-like, and is ultimately converted into 

 a transparent resin; the substance becoming harder and harder 

 with the increase of the chlorine substituted, at length be- 

 coming extremely hard, and cracking in all directions, on 

 cooling, on the surface of the glass on which it has been melted. 

 The action goes on very slowly, but more rapidly with moist 

 than with dry gas. It was continued for several weeks, until 

 no more traces of hydrochloric acid formed could be observed. 



During the operation portions of the substance were taken 

 out at intervals and analysed. 



0*303 grm. of the first portion thus examined gave 0*3495

After an interval of about four days the substance was again 

 analysed. 



I. 0*376 grm. of the substance gave 0-4060 C(X and 0*9085 

 HO. 



II. 0-362 grm. of the substance gave 0*3915 C0 2 and 

 0*1005 HO.
